Patent CA-2041421-A1 (CA)
IPC: B25B7/22
Filed: 1991-04-29
Abstract: A folding utility tool has a handle consisting of a first side and a second side spaced apart by a plurality of spacers.  The area between the first side and the second side of the handle provides a first recess within the handle above the spacers and a second recess below the spacers.  A pair of pivots, one at each end of the handle, allow a plurality of tools to be pivoted from a nested position between the handles to an extended position beyond the handles.  The tools may include such conventional devices as knife blades and screwdriver-can opener blades.  At least one of the tools, however, is a pair of locking pliers having a first jaw and a second jaw pivotable about one of the pivots.  The first jaw is lockable in an extended position while the second jaw is adjustable and pivots about the same pivot point as the first jaw.  An actuation lever and a reaction member provide an over-center mechanism to allow the pair of pliers to be locked with one jaw in a given position relative to the other jaw.  The actuation lever has an adjustment mechanism which allows this relative position to be preadjusted for grasping various objects.
Patent CA-2045801-A1 (CA)
IPC: H04W4/16
Filed: 1991-06-27
Abstract: Downloading of number assignment module designation parameters into a memory circuit of a mobile data telephone set utilizes the built-in voice bandmodem of the set so that service authorization codes and activation can be entered remotely into the subscriber's set thereby initiating cellular service or changing the type of service provided. As described, a cellular mobile subscriber first calls a remote cellular service provider center to establish a voice communication channel between the set and the center. Next, the modem of the set is selectively bridged onto the voice communication channel to achieve data transfer between a source of data located at the remote center and the subscriber's modem. The foregoing enables the remote programming of subscriber's authorization and information into the memory circuit of the mobile data telephone set.

IPC: D05B23/00
Filed: 1991-08-20
Abstract: For selectively inverting flexible and limp planar workpieces (100) such as fabric, an apparatus includes a primary workpiece propeller (112) having a cylindrical means for contacting the workpiece (100) about a central rotating axis. A slot (160) of sufficient size to receive the workpiece (100) is positioned in a substantially vertical orientation beneath the primary propeller (112). The slot (160) preferably has a flared upper end positioned directly beneath and in contact or near contact with the propeller (112). The workpiece (100) is drawn into the slot (160) by the rotation of the propeller (112) and follows the contour of the flared open end of the slot (160). The workpiece (100) enters into the slot (160) until the trailing edge of the workpiece (100) is in contact with the primary propeller (112). The trailing edge of the workpiece (100) is drawn by the propeller (112) to the opposite side of the flared opening of the slot (160) and is subsequently pulled out of the slot (160). Collisions are prevented between workpieces by a control circuit (36) that instructs the apparatus when to eject the workpieces (100). <IMAGE>

IPC: C09K8/512
Filed: 1992-01-28
Abstract: Docket 900010 000 ABSTRACT OF THE DISCLOSURE     A conformance improvement treatment process is provided for reducing the permeability of a higher-permeability zone in a subterranean hydrocarbon-bearing formation which is in fluid communication with a lower-permeability zone of the formation The process includes preparing a gel precursor solution at the surface, injecting the solution into a wellbore penetrating the formation, placing the solution in the higher-permeability zone and gelling the solution therein. In situ gelation of the solution results in substantial permeability reduction to the higher-permeability zone. A specific gel precursor solution is utilized which contains a gelling agent and a polymer formed from at least two distinct monomers wherein the first monomer has a relatively faster, yet controlled, rate of hydrolysis and the second monomer has a relatively slower rate of hydrolysis. Gelation of the solution is delayed until a substantial number of carboxylate groups are formed in situ on the polymer. The gelling agent subsequently reacts with the carboxylate groups to effect gelation of the solution.           RFB

Title: Simulator using a neural network
Inventor: ONO KAZUTERU
IPC: G05B13/04
Filed: 1992-09-25
Abstract: A simulator includes a modelling simulate section in which properties of an apparatus to be controlled are modelled.  In addition, this simulator includes a neural network in which learning is performed depending on a real control quantity for the apparatus to be controlled.  A correction value relative to a simulation control quantity for the modeling simulate section is calculated in the neural network based on a process quantity output from a controlling unit.  Thereafter, the simulation control quantity is corrected depending on the calculated correction value.  In practice, learning is performed in the neural network by changing a synapse load based on a real quantity for the apparatus to be controlled.   As a result of the foregoing correction, the simulator can simulate the real apparatus more accurately.

Title: Protection circuit
Inventor: SHIGA NOBUO
IPC: H03F3/60
Filed: 1992-10-30
Abstract: ABSTRACT OF THE DISCLOSURE       The protection circuit includes a micro strip line whose length is equal to a fourth of the wavelength of an amplification signal frequency on a board and whose one side is connected to the input side of a low noise amplifier, a diode whose one side is connected to the other side of the micro strip line and whose other side is grounded, and a capacitor which is connected to the point where the micro strip line is connected to the diode and whose impedance is sufficiently small  at  the  amplification  signal  frequency.    In  this configuration,  the  diode  has  virtually no effect  to  the amplification signal component because the impedance of the protection  circuit  for the  amplification  signal  frequency viewed from the contact point becomes sufficiently high.  In addition,  for  static  electricity  charged  on  the  antenna connected  to  the  input  terminal,  the  diode  is  virtually connected directly to the input side of the low noise amplifier because the micro strip line is almost zero in resistance.
