Title: Injection molding valve member actuating mechanism
Inventor: CHU SIMON
IPC: B29C45/28
Filed: 1999-02-08
Abstract: Valve gated multi-cavity injection molding apparatus. A number of valve pins extend forwardly from a valve pin plate, each in alignment with a gate leading to a cavity in the mold. A pair of cam bars extend beside a pair of actuator bars attached to the valve pin plate.  Rectangular slide blocks attached to each actuator bar fit in diagonal grooves in the adjacent cam bar, whereby longitudinal movement of the cam bars moves the valve pin plate and the valve pins forwardly and rearwardly. The cam bars are driven longitudinally by electromechanical or hydraulic actuating mechanism to simultaneously and accurately stop the valve pins in at least three different precise positions during each injection cycle.

Title: Crashworthy landing gear shock
Inventor: CARTER JAY W JR
IPC: E05D1/06
Filed: 1997-12-05
Abstract: A shock absorber optionally operable as a retractable landing gear actuator, includes a sealed cylinder divided by a cylinder head to define an upper chamber and a lower chamber, the lower chamber further divided by a piston having a piston rod passing in sealed manner through the lower cylinder end. The cylinder head includes one or more orifices, the effective opening of each orifice controlled by the valve, the valve having a stem attached to and passing through the upper cylinder end to the atmosphere, such that the pressure between the piston and the cylinder head is limited to a certain value above atmospheric pressure, regardless of the velocity or position of the piston.  The valve is forced toward the closed position by a spring such that it is always at least partially open. During hard or crash landings, high fluid pressure on the piston or in the upper chamber forces the valve further open.

Patent CA-2277804-A1 (CA)
Inventor: GALL JOSEPH G
IPC: C12Q1/6841
Filed: 1998-11-16
Abstract: A process for inducing a transcriptionally active chromosome (i.e., a "lampbrush" chromosome) from condensed chromatin or nucleus is disclosed. The condensed chromosome is contacted with the contents of a germinal vesicle.  Preferably, the nuclear envelope is disrupted or removed. Moreover, a heterologous system of chromosome and germinal vesicle derived from organisms of different species is preferred because it permits analysis of organisms that do not have lampbrush chromosomes or cannot be manipulated by other techniques. Such lampbrush chromosomes can be attached to a substrate, and then analyzed by a variety of molecular and cytological techniques such as, for example, antibody detection of chromosomal protein, autoradiography, electron and light microscopy, histochemistry, image analysis, immunofluorescence, in situ hybridization of nucleic acids, morphology, and the like.

Inventor: SAWYER ALBERT JOSEPH
IPC: H04W92/14
Filed: 1999-07-28
Abstract: This invention relates to methods and apparatus for transmitting packets from a source of such packets to one or more radio station sites so that the radio station sites can transmit the packets at the correct real time. Each radio site has an independent source of exact time based on the reception of signals derived from satellite inputs. Using the real time calculated by a base station, the base station calculates an offset between the time of arrival of a signal with a specified time marker, and the time that a signal with that specified time marker should have arrived in order to be transmitted in a timely fashion. The offset is sent back to the source of packets, and used by the source of packets to advance, or retard, the transmission of future packets. Advantageously, packets can be transmitted from each base station at the correct time, and if packets are being transmitted for a given call from several base stations, can be transmitted simultaneously, by these base stations.
Patent CA-2280165-A1 (CA)
Inventor: FOWLER JOHN J
IPC: H05B37/02
Filed: 1998-02-04
Abstract: A multiple sensing technology-based occupancy sensor. Ultrasonic and infrared sensors are used to produce first and second occupancy estimator signals that are combined using a fusion based detection algorithm to produce a combined estimator signal. The combined estimator is then used to switch electrical loads when the combined estimator signal is above a predetermined threshold.  The result is an occupancy sensor that has a very high probability of occupancy detection and a low probability of false tripping. In addition, infrared sensitivity is adjusted based upon an estimation of the background noise in order to minimize the occurrence of false tripping.
