Title: Products and methods for custom dental impression trays
Inventor: FAKHRY ALI
IPC: A61C9/00
Filed: 1994-04-19
Abstract: Products and methods for custom dental impression trays Abstract This invention relates to separator plates for custom dental impression trays, having rod-shaped projections mounted on the plate and perpendicular or somewhat perpendicular thereto. The rod-shaped projections which are preferably cylinders, are spaced, preferably regularly spaced, on the plate. One of the methods for making a remov-able prosthetic for a human mouth, comprises: applying a dental polymerizable material to obtain a custom dental impression tray, to a wax separator plate for custom dental impression trays, while confin-ing the polymerizable material on the wax separator plate with a new pincer. Then the separator plate is applied over a preliminary cast.          After polymerization completion of the polymerizable material, the preliminary cast and the separator plate including the rod-shaped projections are removed, obtaining a custom dental impression tray with spaced, built-in, rod-shaped perforations therethrough.

Patent CA-2149096-A1 (CA)
Inventor: SAWAHASHI MAMORU
IPC: H04W52/24
Filed: 1995-05-10
Abstract: A transmission power control method of a mobile station in a CDMA (Code Division Multiple Access) system which primarily controls transmission power of the mobile station by using a closed loop control which enables high accuracy power control.          When the received power at the base station of a signal from the mobile station suddenly increases owing to the state of buildings surrounding the mobile station, the transmission power of the mobile station must be quickly reduced to prevent the interference to other mobile stations.  The mobile station measures an average value of the received power per transmission power control period of a desired signal from the base station, and detects the difference .DELTA.RSSI between the current average value and that of one of the previous transmission power control periods.  If .DELTA.RSSI exceeds a reference power difference .DELTA.Pth, transmission power PT corresponding to .DELTA.RSSI is set by using an open loop transmission power control to quickly reduce the transmission power of the mobile station.  If .DELTA.RSSI is lower than .DELTA.Pth, the transmission power PT is determined in accordance with the transmission power control bit sent from the base station.

Patent CA-2154802-A1 (CA)
Inventor: MASAKAZU SHOJI
IPC: H01L27/10
Filed: 1995-07-27
Abstract: The present invention comprises a novel memory circuit wherein a plurality of memory cells have passive impedance values representative of the information stored therein.  In the circuit, a signal source having a plurality of outputs is operable to provide a sequence of read signals, one signal per output.  Each of the plurality of outputs is connected to one of a plurality of memory cells.  Each memory cell comprises an impedance element, its impedance value representative of the data value stored therein.  All of the memory cells are thereafter connected to a sum line and a read out circuit. When the signal source provides one of the sequence signals to one of the memory cell impedance elements, it affects the signal on the sum line in a manner that is related to the impedance value of the memory cell.  By applying each signal in the sequence to a different impedance element, the voltage on the sum line is directly affected by each of the impedance elements in sequence. The read out circuit transforms the read out circuit voltage into a voltage level proportional or otherwise indicative of each impedance value, and thus the stored data, in sequence.

Title: Pressed body prepared from plant material by pelletization and device for preparing same
Inventor: HAIMER FRANZ
IPC: B30B11/28
Filed: 1994-06-21
Abstract: The present invention pertains to the problem of compressing biomass, e.g., ripe grain, into solid pressed bodies (1), which are suitable for use as fuel, despite differences in the harvesting conditions, and whose strength no longer depends on the moisture content in the biomass. It was found that this problem can be solved without an essential expense by imparting a wavy structure (6) to the pressed body (1). As a result, the outer surface of the pressed body (1) is compressed more strongly by the extrusion than is the middle cross section area, in which long-fibered parts of the mass are readily oriented in a wave shape (21) and lead to elasticity of the pressed bodies (1), which is favorable for handling.

Patent CA-2172748-A1 (CA)
Inventor: ARGADE PRAMOD VASANT
IPC: H04M1/663
Filed: 1996-03-27
Abstract: A telephone answering machine (104) and method of use utilizes speech recognition (106) to identify a caller from a pre-defined list (111) of possible callers. The list may be generated by various input techniques, including a spoken voice at the called party's location, and keyboard or graphical input techniques. If the caller is identified as being on the list (203), the machine allows the call to progress along a first sequence, which includes ringing the called phone (204). If the called phone does not answer (205), the first sequence may provide for responding with a customized message (212) for the calling party. If the caller is not identified as being on the list, the machine allows the call to progress along a second sequence, which includes responding with a standard recorded message (207). In either case, the caller is typically allowed to record a message for the called party (209). Additional pre-defined lists may be provided, as for determining the context of a call.

Title: Desferrioxamine oral delivery system
Inventor: MILSTEIN SAM J
IPC: C07C235/84
Filed: 1994-10-24
Abstract: Modified amino acids and methods for their preparation and use as oral delivery systems for pharmaceutical agents are described. The modified amino acids are preparable by reacting single amino acids or mixtures of two or more kinds of amino acids with an amino modifying agent such as benzene sulfonyl chloride, benzoyl chloride, and hippuryl chloride. The modified amino acids may form encapsulating microspheres in the presence of the active agent under sphere-forming conditions. Alternatively, the modified amino acids may be used as a carrier by simply mixing the amino acids with the active agent. The preferred acylated amino acid carrier is salicyloyl-phenylalanine. The modified amino acids are particularly useful in delivering biologically active agents, e.g., desferrioxamine, insulin or cromolyn sodium, or other agents which are sensitive to the denaturing conditions of the gastrointestinal tract.
