Title: Cellular telephone with standard telephone set
Inventor: JOGLEKAR MANOHAR A
IPC: H04M11/00
Filed: 1990-04-04
Granted: 1994-11-08
Abstract: A unique cellular telephone (100) connects to a standard telephone set (101) for providing cellular telephone services to subscribers in remote locations not served by a landline telephone system. Cellular telephone (100) includes a cellular telephone transceiver (109), microcomputer (108) and circuitry (102-106) for interfacing the cellular telephone transceiver (109) to the telephone set (101). The interface circuitry (102-107) provides the audio, voltage and dial signal interface to the telephone set (101).

Patent CA-2033064-C (CA)
Inventor: OKADA OSAMU
IPC: H01M8/06
Filed: 1990-05-15
Granted: 1999-08-31
Abstract: Système de production d'énergie par pile à combustible utilisant un gaz combustible qui contient de l'hydrogène en tant que composant principal et que l'on obtient en désulfurisant les combustibles de départ, tels que le naphte, le LPG, le gaz de ville, etc., et en soumettant le gaz résultant à reformage de vapeur. L'invention se rapporte également à un procédé de production de gaz combustible, dans lequel les combustibles de départ sont désulfurisés grâce à l'utilisation d'un agent désulfurisant à base de cuivre-zinc. Lesdits combustibles de départ sont fortement désulfurisés pour empêcher la dégradation du catalyseur de reformage de vapeur. Il en résulte que cette pile à combustible peut fonctionner de manière stable pendant longtemps, et dès lors que le rapport S/C (le nombre molaire de vapeur par mole de carbone d'hydrocarbures dans le combustible de départ) peut être réduit pendant le reformage de vapeur, la teneur en hydrogène du gaz combustible peut être accrue, ce qui améliore le rendement énergétique de la pile à combustible.

Title: Hot gas defrost refrigeration system
Inventor: LAMMERT PAUL F
IPC: F25D21/06
Filed: 1991-02-25
Granted: 2001-12-18
Abstract: A hot gas defrost refrigeration sys-tem has a compressor, a condenser, and an evaporator, interconnected by fluid passage means and incorporating valve means to cause refrigerant to flow se-quentially through the compressor, con-denser, and evaporator to the compressor during the refrigeration cycle. Refriger-ant flow during the defrost cycle is from compressor to evaporator through the condenser to the compressor. The refri-geration system includes defrost passage means, including valve means, connect-ing the evaporator outlet to the condenser inlet and connecting the condenser outlet to the compressor inlet. A vessel is pro-vided which combines the functions of receiver during refrigeration and super-heater during defrost. During refrigera-tion liquid refrigerant flows from the condenser through the superheater/re-ceiver to the evaporator. During defrost, the defrost passage means directs vapo-rous refrigerant from the evaporator through the superheater/receiver to the compressor. The compressor discharge passage to the evaporator includes a superheat passage in heat exchange relationship with the superheater for transferring heat from com-pressor discharge refrigerant to compressor suction refrigerant during the defrost cycle. The condenser is utilized as a reevapora-tor during defrost and the superheater/receiver exchanges heat between compressor inlet and suction refrigerant to enhance sys-tem operation during the defrost cycle.

Title: Efficient feeding frequency
Inventor: HODGE DEAN E
IPC: A23K50/10
Filed: 1992-12-07
Granted: 1998-04-21
Abstract: Ruminant animals, as herbivores, survive and produce while feeding chiefly on grass or other roughage consisting of large amounts of cellulose   Ruminants which have been consuming primarily diets high in cellulose must gradually be adjusted to high grain rations.  When the attempt is made to adapt and feed ruminants diets containing no roughage, metabolic problems surface.  The increase in lactic acid and accompanying fall in rumen pH resulting from roughage or cellulose withdrawal leads not only to the destruction of cellulolytic bacteria which digest cellulose), but to the destruction of lactate utilizing organisms, resulting in acidosis and its attendant adverse effects, which results in less than optimal cattle performance.  Herein roughage can be eliminated allowing ruminants to consume an all grain, properly balanced diet without these adverse reactions.  A roughage free diet for ruminants is provided which alters the eating behavior of cattle.  The diet incorporates ingredients which modify feed consumption patterns of cattle consuming a roughage free diet.

Abstract: Composition de nettoyage aqueuse épaissie qui est visco-élastique et est utile en tant que composition de débouchage de tuyaux ou en tant que nettoyant de surfaces dures, demeurant suffisamment longtemps sur des surfaces non horizontales pour fournir un nettoyage efficace. Dans un mode de réalisation, ladite composition comprend une substance active de nettoyage, un composé d'ammonium quaternaire et un contre-ion organique. Dans un autre mode de réalisation, la propriété visco-élastique de la composition est utilisée avantageusement pour déboucher des tuyaux parce que ladite composition pénètre rapidement dans l'eau stagnante et avec une dilution minimale afin d'acheminer les substances actives jusqu'aux matières obstruantes. Dans ces modes de réalisation et dans les procédés d'utilisation correspondants, une amine libre est limitée par rapport à la quantité de composé d'ammonium quaternaire présent dans la composition, afin de maintenir la stabilité de phase et de conférer à ladite composition des propriétés rhéologiques et esthétiques encore améliorées.

Title: Vehicle shape determination system
Inventor: COACHWORTH SIMON
IPC: G01S11/14
Filed: 1992-08-14
Granted: 2004-02-03
Abstract: A vehicle measure system involves an array of microphones (18) and a spark emitter (24, 46) mounted on a vehicle. Spark ing produces sound bursts which travels to the microphones (18). From detection of transmission times, the position of the emitter (24. 46) is found. Sound velocities arc determined in various directions to ensure the air is homogeneous, else corrections for Sound speed variations are applied or data is rejected. Position data determined from various microphones (18) are compared to ensure repeated measurement accuracy. The apparatus includes simple circuitry with fewer received signal processing channels than microphones (18) and intelligent selection of active microphones in consequence. An emitter can be connected to the upper vehicle body via a bent coupler (78), which can pass around a wing for example. This allows the system, which is ground based, to be used for measurements of the upper vehicle body. The positions of microphones (18) are determined precisely before use of the system, using a calibration jig (124). Errors in microphone positioning are then corrected for in the measurements.

Abstract: A sheet of paper is impregnated with a fluorescein-based dye and a strong organic acid together with a humectant In the presence of the strong organic acid, the normally colored fluorescein-based dye remains colorless on the paper. When a basic gas dissolved in the moisture held by the humectant turns the pH of the paper to the alkaline side, fluorescein-based dye takes on color in accordance with the hydrogen ion concentration. The concentration of the basic gas can be determined by measuring the degree of this coloration.
