Title: Support system for laterally removable sash
Inventor: BATTEN THOMAS F
IPC: E05F1/00
Filed: 1998-02-12
Abstract: A support system for a heavy sash that is laterally removable from between opposed window jambs includes a pair of sash support arms pivotally mounted on each sash stile and counterbalance shoes that engage the support arms to uphold the sash. The support arms, in inwardly dependent positions, can engage the shoes as a sash is lowered onto the shoes; and the support arms, in outwardly extending positions, support the weight of the sash on the shoes.

Title: Method and apparatus for direct shingling of cut sheets at the cutoff knife
Inventor: HARTER RICHARD W
IPC: B65H35/08
Filed: 1998-04-09
Abstract: Shingling of paperboard sheets cut from a web with a helical blade cutoff knife utilizes the downward deflection of the trailing edge of the cut sheet and simultaneous lifting of the leading edge of the web to position the sheets for shingling immediately downstream of the knife.  A vacuum outfeed conveyor takes advantage of the initial downward deflection of the sheet caused by cutting to pull the trailing edge of the sheet onto the vacuum conveyor which is simultaneously slowed  relative to the lead edge of the advancing web.  In the preferred embodiment, vacuum is continuously applied and the conveyor is accelerated back to line speed as soon as the leading end of the web is pulled onto the vacuum conveyor.

IPC: F02D43/00
Filed: 1996-07-21
Abstract: The control operates on an energy-storage injector with an electromagnetic piston pump (11) drawing fuel from the tank (12) and accelerating it into a pressure line (14) through an electromagnetic stop valve (16). The pump has a coil (21) surrounding an armature (22) with a compression spring (24) behind the piston (26).

Title: Method and apparatus for producing dual view displays
Inventor: BORGWARDT STEPHEN P
IPC: G09F19/14
Filed: 1998-05-21
Abstract: A dual view display is described which displays two images, but wherein each image is visible to the exclusion of the other when the display is viewed from particular angles. A sheetlike picture insert bearing interleaved sections of the two images is situated between two transparent frame members having an accordion folded or "zig-zag" configuration. The frame members are thus each formed of an array of planar sections wherein each planar section is at an angle to adjacent planar sections, and wherein every other planar section is parallel to a common viewing plane. When the display is viewed from a line of sight normal to one of the two viewing planes, the viewer sees only a single image, whereas image sections from both images are visible if the viewer sees the display from intermediate lines of sight.

Title: Feature to facilitate numeric passcode entry
Inventor: BRENNAN PAUL MICHAEL
IPC: G06F21/00
Filed: 1998-05-11
Abstract: Information systems which provide access over a variety of devices (e.g. telephones, automated banking machines, computers) typically require that passcodes be numeric to allow entry on all device types. Alphabetic characters are associated with the numeric digits on both telephones and automated banking machines, allowing users to use mnemonic words to remember their numeric passcodes. Computer terminals do not have this association, creating user difficulties. The invention translates text entry on a computer keyboard into the equivalent numeric digits according to an appropriate mapping.

Filed: 1996-12-11
Abstract: L'invention se rapporte à un procédé visant à déterminer si un composé candidat est un agoniste non peptidique d'un récepteur d'hormone peptidique. Dans ce procédé, un composé candidat est exposé à une forme de récepteur d'hormone peptidique présentant une meilleure capacité à intensifier l'activité intrinsèque d'un agoniste non peptidique. L'activité signalant un second messager du récepteur à capacité améliorée est mesurée en présence d'un composé candidat et comparée à l'activité signalant un second messager du récepteur à capacité améliorée mesurée en l'absence du composé candidat. Une modification de l'activité signalant un second messager indique que le composé candidat est un agoniste. Une augmentation de l'activité signalant un second messager indique que le composé est soit un agoniste complet, soit un agoniste partiel; une diminution de l'activité signalant un second messager indique que le composé est un agoniste inverse.

Patent CA-2250789-A1 (CA)
Title: Packet telephone system
Inventor: FRASER ALEXANDER GIBSON
IPC: H04L12/56
Filed: 1997-03-20
Abstract: A packet telephone system which employs a packet network that provides virtual circuits. The packet telephone system employs short packets containing compressed speech. The use of the short packets makes possible compression and decompression times and bounded delays in the virtual circuits which are together short enough to permit toll-quality telephone service. The packet telephone system employs an intelligent network interface unit to interface between the packet network and standard telephone devices. The network interface unit does the speech compression and decompression and also responds to control packets from the packet network. Consequently, many telephone system features can be implemented in the network interface unit instead of in the switches. The network interface unit may also be used to provide data connections to devices attached to it. The combination of virtual circuits, with bounded delays, short packets, rapid compression and decompression, and intelligent network interface units makes it possible to build a telephone system with fewer and cheaper switches and fewer links for a given volume of traffic than heretofore possible and also permits substantial savings in provisioning and maintaining the system.

Abstract: An implantable antitachyarrhythmia device having the capability of detecting multiple tachyarrhythmias, such as ventricular tachycardia and ventricular fibrillation and capable of delivering multiple therapies, such as antitachycardis pacing, cardioversion and defibrillation, In order to assist the physician in understanding the progress of the device toward detecting a tachyarrhythmia and to better understand the operation of the therapy provided by the device, the device transmits information related to these functions on a beat by beat basis, as a supplement to markers signals associated with paced and sensed heart events. The information telemetry regarding detection allows the physician to determine how the particular R-R interval preceding the telemetry has affected the internal counts or order diagnostic parameters required to accomplish tachyarrhythmia detection. Similarly, in conjuction with stimulus pulses, the device transmits information indicative of which of the available therapy regiments is presently in effect.

Title: Clamp for handling different stacked loads
Inventor: SEABERG RICHARD D
IPC: B25J15/00
Filed: 1999-02-12
Abstract: A load clamp has two selectively openable and closable opposing clamping assemblies, one of which comprises at least a pair of clamp arms movable sepa-rately from each other toward and away from the other clamping assembly. Separate actuators for the respective clamp arms are controlled automatically by a regulator in such a way that the respective closure movements of the arms are simultaneous. A selective adjuster assembly enables the operator to select alternate different maxi-mum magnitudes of clamping force to be imposed by the clamp arms on different loads. An override assembly overrides the regulator to permit nonsimultaneous clamp arm movement, automatically in response to resistance to closure by one of the clamp arms, independently of selective variation of such adjuster assembly. Such independence is achieved by overriding the regulator automatically in delayed response to a magnitude of clamping force which is less than the different maximum magnitudes selectable by the adjuster assembly, the delay in response being sufficient to enable such different magnitudes to be attained in accordance with the operator's selection.
