Patent CA-2052129-C (CA)
Inventor: IQBAL MOHAMMAD
IPC: B41M5/52
Filed: 1991-09-24
Granted: 2002-07-02
Abstract: This invention relates to a recording sheet, more particularly, a transparent recording sheet suitable for use with ink-jet printers. Transparencies for use with overhead projectors can be produced by imagewise deposition of liquid ink of various colors onto thin, flexible, transparent polymeric sheets. In the case of imaging onto polymeric film, some means of absorbing aqueous liquids is needed if satisfactory drying of the image is to occur. Because simple polymeric systems are generally either limited in absorbency or in structural integrity, compositions useful as transparent liquid absorbent materials have been formed by blending a liquid-insoluble or low absorbent material with a liquid-soluble, or high absorbent material. A problem that frequently arises in the formulation of polymer blends is the incompatibility of the polymers being blended. When attempts are made to blend polymers that are incompatible, phase separation occurs, resulting in haze, lack of transparency, and other forms of inhomogeneity. This invention provides a transparent recording sheet suitable for ink-jet printers comprising a transparent support bearing on at least one major surface thereof a light transmissive ink-receptive layer containing a hydrophilic polymer crosslinked by polyfunctional aziridine. The recording sheet remains transparent even after ink is absorbed and provides a fast drying, durable, non-tacky transparency suitable for use with an overhead projector.

Title: Switch-adjunct integration arrangement
Inventor: APPLEGATE RANDY LEE
IPC: H04M3/537
Filed: 1991-12-30
Granted: 1996-07-30
Abstract: A switch-adjunct integration device uses multiple line appearances of one or more digital telephone lines to gather information on calls destined for an adjunct voice-mail system, to transfer the calls to analog phone lines leading to the voice-mail system, and to detect call completions. Call completion is detected by bridging some of the line appearances to the analog phone lines and monitoring the bridged line appearances for call status reported thereon by the switch. Call-related information, including call completion, is reported from the integration device to the voice mail system over a control link. The analog phone lines are connected to the voice mail system through switch relays on the integration device. The integration device momentarily opens a relay when it detects call completion on the connected analog line to further enhance call-completion signaling.

Title: Float valve for container-filling systems, in particular systems for filling electric drive batteries
Inventor: ROVER DANIEL
IPC: H01M50/609
Filed: 1991-05-02
Granted: 2005-04-12
Abstract: The invention relates to a float valve (3) for container filling systems, especially for electrical traction battery filling systems, comprising a valve housing (10) that accommodates a valve chamber (11) and a valve head (31), the valve chamber being provided with a filling medium supply inlet (16) and an outlet (17) leading to a container, the valve head (31) being connected to the float via a stem and a float rod (35, 36, 37) and being movably disposed in a valve chamber (11) to open the inlet and the outlet (16, 17) and shut off the outlet (17).      To guarantee quick closing action also with low liquid pressures and to prevent dripping in the closed position it is proposed according to the invention that the filling medium be introduced first in a distribution chamber from where it flows into the valve chamber in a manner that it enters the valve chamber in the bottom area of the latter along the entire surface of the side walls and flows uniformly through the valve chamber. The valve head (31) rests in a recess (13) in the bottom of the valve chamber (11) and is for the most part outside the flow during the filling process. Only when it is lifted out of the recess (13) by the float, the valve head (31) is pushed into the closing position by the flow forces.

Title: Battery saver for a tdm system
Inventor: MOORE MORRIS A
IPC: H04L7/10
Filed: 1990-08-13
Granted: 1996-03-19
Abstract: A power saving method and apparatus in a time division multiplexed system (10) capable of providing a synchronous full duplex communication between a telephone network (12) and a plurality of remote communication units (18). A communication resource controller (14) provides system synchronization, by periodically transmitting synchronization messages through one or more remote sites (11). The communication units (18) attempt to acquire synchronization during a synchronization acquisition in-terval. If synchronization is acquired, the communication units (18) enter a synchronous battery saving mode (515). In the syn-chronous battery saving mode (515), the communication units (18) can detect a call request either to their own address or to the address of another communication unit. If no call request is detected, the communication units (18) reduce power consumption for a synchronous power saving time interval, and thereafter merely verify synchronization. However, if synchronization is not acquired, the communication units enter an asynchronous power saving mode (525), wherein they reduce power consumption for an asynchronous power saving interval.

Title: Flexible suction valve retainer
Inventor: GANNAWAY EDWIN L
IPC: F04B39/00
Filed: 1992-07-23
Granted: 1994-11-08
Abstract: ABSTRACT A flexible valve retainer for a piston and suction valve assembly of a reciprocating piston hermetic compressor assembly. In the compressor assembly, the suction valve opens as a result of the fluid pressure generated by the reciprocating movement of the piston in the cylinder.  As it opens, the suction valve is axially displaced from a closed position on the top surface of the piston to an open position a fixed distance therefrom, whereupon further axial movement is prevented as the suction valve strikes the valve retainer.  The radially outer portion of the valve retainer deflects as a result of the impact with the suction valve.  This deflection of the valve retainer lessens the detrimental effects caused by repeated impact between the suction valve and retainer.  The valve retainer is formed from a flexible material such as spring steel or Swedish steel.  The valve retainer comprises at least one washer coaxial with the suction valve, and spaced said fixed distance therefrom.  In a preferred embodiment, the valve retainer comprises two or three washers stacked one atop another.  The stiffness of the valve retainer is less than about 331,000 lbf/in, and the thickness of the valve retainer is preferably between about 0.028 and 0.060 inch.

Title: Computer system security method and apparatus having program authorization information data structures
Inventor: FISCHER ADDISON M
IPC: G06F12/14
Filed: 1993-04-28
Granted: 1999-06-01
Abstract: Method and apparatus are disclosed including a system monitor which limits the ability of a program about to be executed to the use of predefined resources (e.g., data files, disk writing capabilities, etc.).  The system monitor processes a data structure including a set of authorities defining that which a program is permitted to do and/or that which the program is precluded from doing.  The set of authorities and/or restrictions assigned to a program to be executed are referred to as "program authorization information" (or "PAI"). Once defined, the program authorization information is thereafter associated with at least one program to be executed to thereby delineate the resources and functions that the program is allowed to utilize and/or is not allowed to utilize.  The PAI associated with a particular program may be assigned by a computer system owner/user or by someone who the computer system owner/user implicitly trusts.  The PAI permits an associated program to access what has been authorized and nothing else.  The program may be regarded as being placed in a program capability limiting "safety box".  This "safety box" is thereafter associated with the program such that when the system monitor runs the program, the PAI for that program is likewise loaded and monitored.  When the program is to perform a function or access a resource, the associated PAI is monitored to confirm that the operation is within the defined program limits.   The program is prevented from doing anything outside the authorized limits.

Title: Ice dispenser
Inventor: BEACH SAMMIE C JR
IPC: F25C5/00
Filed: 1993-12-22
Granted: 1996-01-30
Abstract: An ice dispenser provides a storage bin in which ice cubes manufactured by an ice maker are stored until used.  A powered agitator within the bin operates to move cubes to an exit end where they enter a lifting and metering drum.  From the lifting and metering drum the ice cubes, in one embodiment, pass through an adjustable ice crusher which functions to crush the ice into particles the size of which can be changed by adjustment of the crusher. In one position, the crusher can be adjusted so that uncrushed cubes pass through the crusher.          In a second embodiment, a deflector is provided to allow the ice cubes to bypass the crusher when uncrushed cubes are required.  The deflector is moveable to a position to cause the cubes to pass through the crusher and for delivery of crushed ice.  The lifting and metering drum operates at a lower speed than the agitator or crusher and is driven by gearing connecting the lifting and metering drum with the agitator.  Similarly, the crusher is driven by gearing connecting the crusher with the agitator.  Speed of the agitators is substantially greater than the speed of the lifting and metering drum.
