Patent CA-2043712-A1 (CA)
Title: Food storage
Inventor: FRENCH MADELINE S
IPC: A23B7/154
Filed: 1991-05-31
Abstract: ABSTRACT Food Storage To an increasing extent, vegetative foodstuffs such as vegetables and salads are not prepared freshly at the point of use but are prepared remotely and distributed to catering establishments or via the retail trade.   It is desirable to disinfect such pre-prepared foodstuffs, but the use of an aqueous solution of an organic peracid can reduce the shelf life of the foodstuff by causing or exacerbating discolouration and/or decrisping.    The problem is ameliorated by subsequently contacting the disinfected foodstuff with a neutralising solution of thiosulphate.  The process is particularly suitable for potatoes, beansprouts and leaf vegetables such as cabbages and lettuces.     143xp-cs

Title: Game apparatus and memory cartridge used therefor
Inventor: YAMAMOTO MASAO
IPC: A63F13/52
Filed: 1991-06-20
Abstract: A player initially sets the degree of difficulty of a display type game, and if desired, more than one player may participate with each player selecting an associated level of difficulty. First and second objects having different shapes, e.g. capsules and viruses, and different characteristics, e.g. different colours or shadings, are displayed in a predefined display area. First objects are generated based on random number data stored in a ROM and displayed as "falling" in a vertical direction across the predefined display area. Coordinate positions of the first objects on the display are changed by a player operating a controller. Second objects are displayed at arbitrary positions in the display area based on random number data.      If a prescribed number of at least a portion of first objects and/or second objects having the same type characteristics are detected as being continuously aligned in a vertical or lateral direction, those continuously aligned objects are erased. Remaining portions of first objects (or remaining first objects) previously supported by erased objects are displayed as falling in the vertical direction to the lower region of the prescribed display area. When all second objects are erased, the game is successfully completed.

Title: Electric device of hydrogenated amorphous silicon and method of manufacture
Inventor: KANBARA TERUHISA
IPC: H01L31/0224
Filed: 1991-06-28
Abstract: ABSTRACT OF THE DISCLOSURE      Electro-migration of electrode metal takes place under  an elevated  temperature condition in amorphous silicon devices having conventional PI-type, NI-type, or PIN-type  hydrogenated  amorphous  silicon  layered structures, which substantially degrades the electrical characteristics of the device.  This problem is solved by forming a chemically inactive layer consisting mainly of amorphous  silicon oxide  on the surface of amorphous silicon layer by a washing  and drying process,  to establish  electrical  contact  through  the chemically inactive layer between the hydrogenated amorphous silicon layer and either a collector electrode or a transparent electrode.  This structure not only substantially prevents such electromigration of electrode metal, but it also allows greater freedom in choosing a material for the collector electrode.

Abstract: Methods are provided for chemically consolidating subterranean formations around wells using resins.      Resins are forced into the formations by high pressures instantaneously applied when perforations are formed in casing in wells or when pressures are released from tubing in wells. Perforating, explosives or gas generators may be used in addition to the high pressures for driving resins into formations.

Filed: 1991-02-13
Abstract: A method and system for the biological disposal of oxalate is described in which a biological reactor (10) having an alkalo-philic oxalate-degrading aerobic micro-organism in aqueous solution is employed. The biological reactor (10) comprises a vessel (12) containing the aqueous solution and having an input (14) for receiving dissolved oxalate from dissolver tank (24). Sodium oxalate (1), as a by-product of the Bayer process in an alumina refinery, can be introduced into the dissolver tank (24) in solid form together with trace elements and nutrients (3) for biological growth. The system operates as a continuous feed process with dissolved oxalate being pumped from tank (24) into vessel (12) continuously in a controlled manner. The biological reactor (10) further comprises an aerator (18), including an oxygen probe (20) for monitoring the level of dissolved oxygen in solution. Bio-logical degradation of the sodium oxalate in a highly alkaline solution occurs in the biological reactor with sodium carbonate and bicarbonate formed as end products in the effluent. The effluent is then pumped to causticiser reaction tank (28) and settler tank (34) for converting the sodium carbonate and bicarbonate in the effluent to useful sodium hydroxide which can be recycled in the Bayer process. A novel alkalophilic oxalate-degrading aerobic micro-organism of the Bacillus species is also described.

Abstract: MULTIPLE PARTICIPANT MOVING   VEHICLE SHOOTING GALLERY                                       ABSTRACT An interactive system that employs moving vehicles in which participants ride and from which they engage computer-generated pop-up and prepositioned simulatedtargets using simulated weapons. The vehicle carries the participants a predetermined distance using a track or trough-guidance mechanism through a covered and darkened path as they engage the simulated targets. Each participant operates independently of the others and engages targets that are displayed during travel along the track. The participants occupy seats having safety restraints, and operate a fixed, swivel-based simulated weapon and sight it to fixed targets having predetermined locations and to the targets generated by a computer in accordance with a preselected scenario. Each vehicle has a transponder that provides continual broadcasts of location and game data. This coordinated data specifically locates a moving eyepoint so that the portrayed scenes can be made geometrically correct. This also gives the illusion of 3-D depth through perspective and parallax effects.
