Title: Supplementary coding on inductive debit cards and reading process
Inventor: CALCAVARA ENIO JR
IPC: G06K19/00
Filed: 1995-05-11
Abstract: Supplementary coding on inductive debit cards and reading process refers to supplementary information regarding variables such as date of issue and country in which the card is valid, which are included without any change in the number of credits on the card by using the front and back handling strips (17, 18). Such an encoding comprises the division of said strips, in a number of segments or tracks (41, 42, ... 49) equal to the number of cell columns on the card, coinciding the center of said tracks with the axes (31, 32, ... 39) of said columns; the metallized tracks correspond to bit "1" and the nonmetallized tracks to bit "0", the four tracks located at the corners of the card (41, 49, 41', 49') being always metallized. The reading of the information on the card is carded out during the insertion of the card (30) into the reading head by the row of sensors (64) the farthest away from the entrance slot (69). On detecting the presence of a pair of metallized tracks on the corner of the card, the bits contained in either strip are read and stored in a temporary register for a later interpretation.

Title: Cdma air interface for radio local loop system
Inventor: GORDON MALCOLM
IPC: H04B1/707
Filed: 1996-11-07
Abstract: The capacity of a code division multiple-access (CDMA) net used for a radio local loop system can be increased by exploiting the fixed nature of subscriber stations (3). Orthogonal spreading codes are used for both the forward (12,16) and reverse links (17) and the transmissions from the subscriber stations (3) are adjusted so thatsignals received at the base station (1) from the subscriber stations (3) are synchronised with respect to their spreading codes to within a chip period. Accurate synchrinisation, time control and carrier frequency error compensation of the code division multiple access transmission from multiple subscriber stations (3) reduces the level of multiple access interference experience on the reverse link (17) (from subscriber to base station) which is normally the principal limiting factor on the capacity of a system employing CDMA.

IPC: F16K31/68
Filed: 1992-03-13
Abstract: A  thermostatically  controlled  mixing  valve  having  a modular cartridge  mounted  in  a  housing.   The  cartridge comprises a tubular sleeve having rotatably disposed therein a hollow cylindrical housing.   The bottom of the cylindrical housing has  a volume control valve plate attached against rotational movement thereto.  The volume control valve plate cooperates with a fixed valve plate with which it is in surface-to-surface  contact  to control  the volume  of water flowing into the cartridge.  The fixed valve plate is affixed against rotational movement to a nose piece which is fixedly attached  to  the  bottom  of  the  tubular  sleeve.   An  inner housing is disposed within the hollow cylindrical housing and defines therewith cold and hot water inlet passageways which are in communication with a mixing chamber in the interior of the inner housing through hot and cold water supply openings.          A  thermostat  construction  responsive  to  the  mixed  water temperature is axially movably disposed in the mixing chamber and is operably connected to valving means adapted to open and close the hot water  supply opening and cold water  supply opening.   The  valving  means  comprise  a  cylinder  fixedly mounted on the top of the inner housing with the bottom of the cylinder and the top of the inner housing defining the hot water  supply  opening,  and  with  the  top  of  the  cylinder defining with an inner shoulder in the cylindrical housing the cold water supply opening, and a piston operably connected to said thermostat construction and axially slidably disposed in said cylinder.  Upward movement of the piston in the cylinder serves  to  close  off  the  cold  water  supply  opening  while downward movement of the piston serves to close off the hot water  supply  opening.   An  increase  in  the  mixed  water temperature in the mixing chamber results in axially downward movement of the thermostatic element with consequent downward movement of the piston thereby resulting in restriction or closure of the hot water supply opening.  A decrease in the mixed  water  temperature  in  the mixing  chamber  results  in axially  upward  movement  of  the  thermostatic  element  with consequent upward movement of the piston thereby resulting in restriction  or  closure  of  the  cold  water  supply  opening thereby maintaining a preselected water temperature in the mixing chamber.

Abstract: Methods for preparing low-fat and/or fat-free viscous dressings, especially low-fat and/or fat-free mayonnaise products, containing inulin as a fat mimetic are provided. These low-fat and/or fat free viscous dressings generally have excellent organoleptic properties and shelf-stability. The low-fat and/or fat-free viscous dressings are prepared from aqueous xanthan solutions, non-creamy and non-gelled inulin solutions or slurries, and aqueous cooked starch solutions. The aqueous xanthan solution (and sometimes the inulin solution) is exposed to high shear to form a non-gelled premix. The non-gelled premix is then mixed with either (1) the aqueous cooked starch solution (if the inulin is contained in the premix) or (2) the aqueous cooked starch solution and the aqueous non-gelled inulin solution or slurry (if the inulin is not contained in the premix). The mixing with the premix is generally under low shear conditions. The so-produced viscous dressing reaches the desired texture in 3 to 12 days.

Patent CA-2207745-A1 (CA)
Inventor: KORNFELD RICHARD K
IPC: H04B1/7075
Filed: 1995-12-11
Abstract: The method and apparatus of the present invention improve the immunity to interference of a radio receiver. The power level of a received signal is detected. If the power level meets or exceeds a predetermined power threshold, the low noise amplifier (703) is by-passed (730), thus increasing the intercept point of the receiver components. Alternative embodiments include the use of an RF power detector (105) to control the front-end gain (110) as a function of jammer power. In lieu of a switchable RF gain block (730), several methods of continuous gain control are proposed. Continuous gain control allows the interference suppression and sensitivity of the receiver to be adjusted at lower signal levels than the switchable gain block. A method of the present invention adjusts the input gain by a predetermined amount (1601). The receiver processing measures the gain change in the IF signal power (1605). If the change is less than the predetermined amount (1610), the CDMA signal and jammers are below the noise floor and, therefore, the gain is increased (1615). If the IF signal power change is greater than the predetermined amount, the interference is evident and the gain is reduced to reduce the intermodulation products (1620). This process is used until the receiver is operating at the best compromise between interference and noise figure.

Abstract: Tungsten carbide cobalt and tungsten-containing materials are recycled using a single high-temperature oxidation with standard dilution chemistry. The scrap material is ground, oxidized, and subjected to an acid digestion, preferably in hydrochloric acid. This causes the cobalt to form cobalt chloride while the tungsten remains insoluble. The pH is then increased to about 7.0 which causes the cobalt chloride to form cobalt hydroxide which precipitates out of solution. The cobalt and tungsten are separated and dissolved in a high-pH ammonia solution which can then be spray dried to form a precursor powder for subsequent carburization to form tungsten carbide-cobalt powders.
