Title: Capacitive Discharge Ignition System with Self-Triggering Solid State Switch
Inventor: DOLMOVICH BRUCE E
IPC: F02P3/08
Filed: 1993-09-09
Abstract: A capacitive discharge ignition system is described that incorporates a two-terminal passive network for controlling the discharge of a capacitive energy storage device into an igniter plug, wherein the network comprises a solid-state switch for alternately providing high and low ohmic paths between the two terminals in order to selectively connect the capacitive energy storage device to the igniter plug.  The passive network includes means  responsive to a predetermined value of a voltage differential between the two terminals for effecting the switching of the path between the two terminals provided by the solid-state switch from a high ohmic value to a low ohmic value, thereby controllably discharging the capacitive energy storage device into the igniter plug. In the illustrated embodiment, the solid-state switch is a series of SCRs, each of whose anode is connected to the trigger input of the SCR by way of a breakover diode.

Title: One step pcr for detection of rare rna and dna
Inventor: VIERLING JOHN M
IPC: C12Q1/68
Filed: 1993-09-29
Abstract: A one step PCR technique for the detection of rare RNA and a combined one step PCR technique for the simultaneous detection of DNA  and RNA is provided which offers several important advantages over traditional PCR. The simplified procedure of the one step RNA  PCR and the combined one step PCR technique for the simultaneous detection of DNA and RNA and elimination of the potential for contamination with repeated opening of the reaction tubes reduces both labor intensity and the risk of false-positive results. In addition, the RT-PCR incubation program can be substantially shortened in the one step method and the combined one step PCR technique for the simultaneous detection of DNA and RNA. The increased intensity of reaction products using specimens containing both plus and minus stranded HCV RNA also favors the one step method. Thus, the one step RNA PCR is an attractive alternative to traditional RNA PCR for the detection of HCV RNA. And the combined one step PCR technique for the simultaneous detection of DNA and RNA is an attractive alternative to the separate use of traditional RNA  PCR and DNA PCR for the detection of HCV RNA and HBV DNA. The reduced risk of contamination and time required for each assay make these techniques particularly well suited for testing of multiple clinical specimens.
Patent CA-2126503-A1 (CA)
Inventor: CROWTHER WILLIAM R
IPC: H04L29/06
Filed: 1994-06-22
Abstract: ABSTRACT OF THE DISCLOSURE    The classifier device disclosed herein analyzes message headers of the type which comprise a sequence of bit groups presented successively.  The device employs a read/write memory for storing at a multiplicity of addresses, an alterable parse graph of instructions.  The parse graph instructions include node instructions which comprise opcodes in association with respective next address characterizing data and terminator instructions which comprise identifying data for previously characterized header types.  A logical processor responds to a node instruction read from memory either by initiating another memory read at a next address  which, given the current state of the processor, is determinable from the current node instruction and the current header bit group or by outputting data indicating recognition failure if no next address is determinable.  The logical processor responds to a terminator instruction by outputting respective header identifying data.  Accordingly, for a previously characterized header type, a corresponding pattern of node instruction and a terminator instruction can be written into memory thereby enabling the device to identify the respective header type in a time which is essentially proportional to the length of the header and thus also to the time of presentation of the header.  The parse graph can be updated dynamically during the operation of the classifier.

Patent CA-2135243-A1 (CA)
Title: Patient care system
Inventor: FERRAND ROBERT J
IPC: A47C20/04
Filed: 1994-11-07
Abstract: A bed comprises an inflatable mattress supported on a platform of articulable links by a support system mounted on a weigh frame.  The weigh frame is supported on a base frame supported relative to a floor. A pneumatic system includes a platform-mounted blower directing air through passageways in the articulable links.  An exhaust passageway parallels the pressure passageway for exhausting opposite the blower. Air flow into and out of air cells in the mattress are controlled by valves coupling the pressurized air chamber and exhaust chamber to cell ports.   A connector assembly is used to couple the cells to the platform, to adjacent cells, and to tubes connected to other cells.  An alternative pneumatic system includes fans distributed on the platform in association with sets of mattress cells.  A footboard assembly is formed as two gates that swing out from the foot of the bed.  Each gate has a storable tray that is positionable on either side of the gate. A headboard has a removable central panel for providing emergency patient access.   Additionally,  each corner of the headboard has a telescoping equipment support post positionable at a variety of heights and having equipment supports that automatically drop into place upon removal from storage in the headboard.  A three-point weight sensing system tracks patient weight and generates pre-exit and exit alarms based on sensed movement of the patient on the mattress.  A portable control unit wraps around a guard rail to provide both patient and nurse controls, and uses a unitary membrane to cover exposed faces of the controls and resiliently wrap around the guard rail.   Selectively engageable guide or fifth wheels are mounted to the base frame to provide direction stability during bed movement.   The platform is articulable to allow a patient to enter or exit the bed in a standing position.  An adjustable stand up board is selectively positionable at the foot of the bed to take the patient's weight during this process. A vertically telescoping guard rail elevation system provides energy storage to resist lowering and assist raising the guard rail.  A brace is provided for seating the platform on the weigh frame when the bed is in a low position and to assist in movement of the bed longitudinally when in the low position.  An expanding joint between panels allows the panels  to  separate with increasing angle between the panels.   A hydraulic valve produces linear changes in fluid flow with linear changes in a valve plunger.

Patent CA-2139860-A1 (CA)
Inventor: WERNER HEINZ
IPC: B23C5/20
Filed: 1994-05-25
Abstract: A cutting insert intended to be fixed in a milling cutter is circle-round to an extent of about 3/4. The remaining fourth comprises two mutually substantially perpendicular side surfaces (4 and 5), whereby a part (6) of one of the two side surfaces adjacent to the corner between them forms a parallel land and is inclined so that it forms an obtuse angle with both said surfaces. By this rounded construction, the angle of the parallel land (the angle between the parallel land cutting edge (11) and the machined surface) can be adjusted very accurately, which results in smooth surfaces, without changing the preset clamping force of the cutting insert.

Title: Method of operating a voltage converter, and a voltage converter and its application
Inventor: OHMS FRANZ
IPC: H02M3/337
Filed: 1993-10-04
Abstract: In a voltage converter for switching mode,  for example a push-pull voltage converter  (GW),  during a starting  operation  the  switching-on  pulses  for  the switching elements  (S1,  S2)  are dimensioned to be of different length,  specifically in such a way that the mean value  of  the  energy-consuming current does  not exceed a prescribed limiting value.        By contrast with conventional methods, there is no  regulation  of  the  switching-on  pulses,  but  the different switching-on times in a plurality of subphases are prescribed in a fixed fashion as a function of the inductance (LS) of the DC/DC voltage converter (GW).        The method according to the invention ensures that the mean value of the inrush current cannot become substantially higher than a prescribed nominal value. This is advantageous, in particular, for the power supply of travelling wave amplifiers.
