Lethbridge Herald, The (Newspaper) - November 21, 1974, Lethbridge, Alberta Thursday, 21, THE LETHBRIDGE HERALD Video revolution goes Underground I Seaway freighter sinks KUMONTON (CP) The "video which has spread to many Alberta schools, businesses and social agencies, may be going un- derground Techno Audio-Video Serv- ices Ltd. has designed a video camera which could be pulled through sewer and water mains to examine the pipes, says John de Vries, president The custom-made camera was designed in response to a request by the city of Edmon- ton for tenders on an in- spection system for the under- ground lines, and is the latest of the four-year-old com- pany's video innovations. Video cameras and video tape include a camera and an audio unit to record pictures and sound for projection through a tele- vision caught on in almost every sector of Ca- nadian society. Techno Audio-Video, which has taken advantage of the trend, has a small staff of two technicians and four sales- persons, but it brings in 000 to a month selling, servicing and renting equip- ment throughout Alberta, Sas- katchewan and the Northwest Territories. CAN PLAY BACK While filming is a photo- graphic process, video taping is a magnetic process, ex- plained Mr. de Vries Whereas film must be processed before it can be seen, videotape can be played back immediately. The single largest user of video tape equipment is the educational sector, he said. Of about half-mch-tape video tape recorders (VTR) in the province, about are found in the schools. Canada's first video tape dubbing centre was estab- lished in Edmonton four years ago by the provincial educa- tion department. Since then, the centre has distributed countless copies of videotaped programs from Canadian, American and British tele- vision sources, educational in- Calgary professor develops new oxygen extraction method CALGARY (CP) Five years ago. Dr. Robert A. Rit- ter, then dean of engineering at the University of Calgary, was trying to develop a chem- ical process with commercial applications and stumbled upon a simple method of pro- ducing near-pure oxygen from ordinary air. Dr. Ritter. now president of Ritter Engineering Ltd., and his long-time assistant, David G. Turnbull, were studying a process called adsorption chromatography as a possible method of producing poly- styrene, a common plastic used in the manufacture of a wide variety of products. They decided by sheer chance to test the process, which uses the ability of cer- tain molecules to attract and hold other molecules, on air before trying it on ethyl ben- zene, the raw material from which styrene was to be ex- tracted. After a few tests they dis- covered they had found some- thing they weren't looking easy way to produce an almost pure oxygen. They developed an adsor- bant or molecular sieve to hold nitrogen, which con- stitutes 78 per cent of atmos- pheric air, while permitting oxygen to pass through. 95 95 PER CENT PURE The adsorbant, consisting of aluminum silicate and cal- cium cations, is capable of producing oxygen of up to 95- per-cent purity. To provide a continuous flow of oxygen, two sieves are used in each separator unit, with one producing oxygen while the other, under the in- fluence of a vacuum, cleans itself of nitrogen. The sieves alternate their functions at two-minute intervals. With the exception of pre- cision metal-cutting, which requires 100-per-cent pure oxygen. Dr. Ritter said the oxygen produced by the separation process can replace bottled oxygen produced by conventional methods in almost all medical, commercial and in- dustrial applications. Confident that they had an invention of commercial sig- nificance, Dr. Ritter and Mr Turnbull resigned from the university last summer to de- vote full time to Ritter Engi- neering, which holds the pat- ent rights for the process. Mr. Turnbull is vice-president of Ritter Engineering. The first Ritter Engineering model is the Reox 2500 sys- tem, designed for m-home use by patients who need to breathe oxygen due to dis- eases such as emphysema, chronic bronchitis, asthma, bronchiectasis and cystic fibr- osis. AIDED BY GOVERNMENT The Alberta government, which helped Dr. Ritter start his company through a grant and loans, placed the first or- der for 30 Reox 2500 models. The health department loans the units to patients for use at home on a trial basis. One of the patients using the unit is Irene Kettner. 45. a Calgary housewife who was previously hooked to an oxy- gen bottle, spent a lot of time in hospital and was unable to do much exercise or work. Mrs. Kettner. an oil-com- pany librarian until two years ago when she developed a heart condition which com- plicated a breathing problem she has had since her left lung was removed when she was 17. is full of praise for the machine. "This unit gives me mobil- ity which I didn't have with the oxygen bottle." she said. "It's easy to operate, safer to MELROE BOBCAT Skid-steer Loader That "Puts It All Together C J EQUIPMENT Sales Service 1410 ZndAve.S. -Phone 327-2922 use and much cheaper It takes away the depression I had with the oxygen bottle Dr Ritter said the average cost of operating a Reox 2500 is a month, compared with more than for bottled ox- ygen. But the bigger savings are in hospital bills, about per patient day in Alberta. Other advantages of the ox- ygen separator include eliminates the pos- sibility of explosion of bottled security of sup- ply, as all the unit needs is household electric current and air. Dr. Ritter said it is econom- ically viable to produce Reox systems with a capacity of up to 10 tons of oxygen a day Above that capacity con- ventional methods are pre- ferred. There have been inquiries from hospitals and nursing homes about using Reox sys- tems as a central source of ox- ygen. Dr Ritter said the process promises wide applications in other fields, such as cutting and welding, on ships and air- planes, chemical manufac- turing and "whenever there is a need for a small quantity of oxygen." MAY PRODUCE HELIUM "It can be applied in the separation of other gases and liquids Dr. Ritter said one area he is seriously looking into is the production of helium from natural gas. Helium, a rare gaseous ele- ment which is lighter than air and does not burn, is irrepla- ceable because once it is lost it escapes to the upper atmos- phere. Used in balloons and other lighter-than-air appli- cations, helium is so ex- pensive to reclaim by known methods that it is being wasted Dr. Ritter estimates that about S25 million worth of he- lium is being lost in natural gas production in Alberta an- nually Dr Ritter. 43. was born in Regina and received his de- grees in chemical engineering from University of Saskatche- wan and University of Al- berta. He taught at University of Alberta and University of Calgary for 19 years Mr. Turnbull. 45. was born in England and came to Can- ada in 1952.

"They show individuals who have gone through the pro- gram and give testimonials WOMEN GET GRANT In Calgary, a group called Videowomen obtained a Local Initiatives Program grant to express themselves through taped productions.

"Video tape recorders are as easy to use as a vacuum cleaner but much more fun." said a spokesman for the group The Alberta Native Commu- nications Society has video- taped a series of programs on native history and current events, which have been aired by cable television com- panies.
