Patent CA-2184076-A1 (CA)
Title: Improvements relating to pulsed droplet deposition apparatus
Inventor: TEMPLE STEPHEN
IPC: B41J2/045
Filed: 1995-03-16
Abstract: The selected ink channels of a drop-on-demand ink jet printer are caused to expand and then contract, ejecting ink droplets by the application of unipolar voltages first to selected channels and then to non-selected channels. Further unipolar voltages, delayed in time by 2L/c and scaled by a pressure wave reflection coefficient r of the nozzle, effect prompt cancellation of residual pressure waves so that adjacent channels are ready for actuation with minimum delay.

Title: Pacemaker with vasovagal syncope detection
Inventor: MARKOWITZ H TOBY
IPC: A61N1/365
Filed: 1995-03-08
Abstract: Pacemaker with improved detection methods for occurrence of vasovagal syncope episodes. Increased rate pacing followed by fallback to lower rate is a retained feature. The lower rate need not be related to the increased pacing rate. One alternative detects stable or persistent rate below a threshold rate after a rapid rate drop through the threshold rate. Another alternative detects a "top rate" as a highest persistent rate and compares the difference between it and the rate that follows a rate drop through a "drop rate" or other threshold level. Yet another alternative finds a persistent rate above a first threshold rate before initiating the rate drop detection function. Once initiated, this embodiment preferably detects a rate drop from above said first threshold to below a second threshold rate, and also preferably detects a stable rate below said second threshold rate. Adaptations to avoiding pacing activation during sleep and combinations of the various embodiments are discussed.

Title: One-piece dispensing device for the contamination-free administration of medicaments (cytostatica)
Inventor: LEIBITZKI HARRY
IPC: A61J1/00
Filed: 1995-04-25
Abstract: The invention concerns a one-piece dispensing device which can be used for the contamination-free administration of medicaments (cytostatica) and is particularly suitable for use in ambulant treatment.  The aim of the invention is to design a connector for connecting medicament (cytostatica) containers to the instruments by which the medicaments are administered, the connector being designed to prevent, without a complex apparatus, contamination of the medicament container surroundings during connection of the container and until its disposal.  This is achieved according to the invention by the provision of at least one coupling member (1) to create a non-releasable connection with a medicament container, said coupling member (1) having an insertion pin (2) and barbed surfaces (10) to accommodate the medicament container.  The coupling member (1) is non-releasably connected via a hose (3, 31) to a flexible container (4; 41) which can be filled exclusively with gas until the device is first used.  The container (4; 41) is non-releasably connected to a further tubular outlet (6) and a mechanically actuated stop valve (5, 7) is incorporated in each of the connecting ducts (3, 31, 6).

Title: Systems and methods for providing increased server performance in a communications network
Inventor: BLONDER GREG E
IPC: H04L29/06
Filed: 1997-06-19
Abstract: Systems and methods for automatically increasing server performance in a communications network are presented. Individual servers are provided with the capability to automatically reject incoming communications when a performance evaluation by the receiving server indicates that performance will be significantly, negatively affected by processing the new communication (i.e., the server will begin to be overloaded and performance will suffer). In rejecting the incoming communication, the server sends the received packet back to the sending server along with a rejected message and a secondary transmission address (i.e., an alternate end-server). The initial sending serverthen re-transmits the communication using the secondary address as the primary address. The techniques of the present invention are particularly applicable to servers used to provide toll free service -- where the dialed number is not the actual destination number. Other applications of the present invention are also disclosed.

Title: Camber adjustment assembly for a wheelchair
Inventor: PETERSON CHRISTOPHER J
IPC: A61G5/10
Filed: 1997-06-27
Abstract: The  present  invention  is  directed  to  a lightweight wheelchair having adjustable wheel camber, adjustable toe-in/toe-out positions,  and  front-to-rear adjustment of the wheel assembly relative to the frame. The wheel camber is changed by removable camber tubes having plugs  in opposite ends with different  angular relationships.  The camber tube is removed from an axle tube,  rotated through one hundred eighty degrees,  and reinserted to change the wheel camber.  The location of the angular recesses in the camber plugs addresses minor toe-in/toe-out adjustments while rotation of an axle tube provided with indicia assures that proper toe-in/toe-out adjustment   is   provided   for   larger  wheel   camber adjustments.   The front to rear location of the wheels relative  to  the  frame  can  be  adjusted  via  a  single fastener on each side.  Moreover, the track width of the rear wheels can be adjusted in response to the change in wheel camber.

IPC: F01N3/027
Filed: 1997-10-21
Abstract: A meshed plate-like heater is disposed between multi-layer cylindrical filters without contacting with the filters to constitute a DPF.  The heater has a form in which strip-like electric conduction paths are arranged and developed side by side horizontally, and then made cylindrical such that the different electric resistance are set for the inlet portion, the outlet portion and the center portion so as to constitute a DPF 100 for regenerating the particulates.  The regenerative heater realizes a uniform temperature distribution all over the regenerative heater within a range of from about 600°C which is the self-burning temperature of the particulates to 1,000°C which is the heat-resistance temperature of the filters, in 10 minutes after the start of regeneration.
