Patent CA-2221267-A1 (CA)
Inventor: LIU LIANG-JUNG
IPC: H01R13/453
Filed: 1997-12-09
Abstract: A safety socket for avoiding danger of shock due to insertion of alien article into the insertion hole. The socket is disposed with three spaced partitioning boards defining three apartments. The partitioning boards are arranged according to the direction of the arrangement of the insertion holes of the socket. Three wedge-shaped insulative slide boards are disposed on the partitioning boards, which are left and right slidable within the apartments. Three short leaf springs and three sets of leaf spring seats are respectively disposed in the apartments. A leaf spring extends from each leaf spring seat to contact with a corresponding short leaf spring.          The  slide  board  is  restricted  to  resiliently reciprocally slide within a slot  formed on the  leaf spring seat. By means of the leaf spring, when the plug is not inserted into the socket, the short leaf spring or the leaf spring always pushes the slide board in a direction reverse to the corresponding leaf spring, whereby the leaf spring is normally in an open state.          Reversely, when the plug is inserted into the socket, each two corresponding leaf springs contact with each other into a powered on state. When an alien article is inserted into one insertion hole, the alien article will push the slide board on one side to move, whereby the insertion hole on the other side is powered on, while the insertion hole on the insertion side is not powered on so as to avoid danger of shock.

Patent CA-2225083-A1 (CA)
Inventor: SHULL ANDREW G
IPC: F15B11/20
Filed: 1997-12-18
Abstract: An electrohydraulic control system for loading a bucket of a work machine includes sensors for producing signals representative of bucket position and forces. A command signal generator receives the signals and calculates a target angle on the basis of accumulated energy, and a force vector angle representing actual forces produced at an reference point on the bucket. Lift and tilt command signals are modified in response to differences between the target and actual angles, and used to controllably extend the lift cylinder to raise the bucket through the material, while racking the bucket at rates calculated to efficiently capture the material.

Title: Wet silica gels for aerogel and xerogel thermal insulation and processes for the wet gels
Inventor: STOVER LISA A
IPC: C01B33/155
Filed: 1998-02-06
Abstract: A wet silica gel can be prepared by a process comprising the steps of contacting a stable, aqueous, fluid silica system having a pH greater than 7.5 with an ion exchange resin which removes metal ions and replaces them with H+ ions and thereby reduces the pH to less than 5.0, adding an organic liquid to the aqueous silica system, providing, however, that the organic liquid added stays in one phase with the aqueous, silica system, and does not cause the silica to precipitate, and adding a base to the silica system so that the pH of the silica system is in the range of from about 5.0 to about 7.5, and allowing the wet silica gel to form. The wet silica gel formed by this process is characterized by its high organic solvent content and the low concentration of basic metal ions.

Patent CA-2233981-A1 (CA)
Title: Device for holding a fluidic component
Inventor: GESER JOHANNES
IPC: B05B1/00
Filed: 1996-10-04
Abstract: The mounting of a component subjected to pressure from a fluid requires special precautions if the component is made of wear resistant, hard and hence generally brittle material and may be destroyed by locally raised stresses.      A fluidic component of this kind, (e.g. made of silicon/glass) is arranged in an elastomeric shaped component, e.g. made of silicon rubber, the contours of which correspond to the outer contours of the component and to the inner contours of a holder.      Because of the "floating mounting" there are no unacceptable local pressure peaks and no deformation of the fluidic component. The device is particularly suitable for mounting a fluidic component made of glass or silicon, of miniature dimensions, subject to high pressure.

Patent CA-2242575-A1 (CA)
Title: Optical amplifiers providing high peak powers with high energy levels
Inventor: SCIFRES DONALD M
IPC: H01S3/10
Filed: 1997-01-10
Abstract: Two approaches are provided for achieving an optical amplifier system capable of producing high peak power, high energy pulse outputs while suppressing scattering noise. The first approach relates to an optical amplifier system which has at least one laser diode pulsed or cw pumped double clad fiber amplifier utilized for receiving a high frequency modulated injected signal pulse of short duration from the laser diode, via the fiber core, for amplification by coupling pump light into the inner cladding of the fiber. The average signal power is sufficient to saturate the gain of the fiber so as to minimize significant onset and buildup of forward and backward scattering noise. The duty cycle of the injected signal source pulse is chosen to allow adequate gain recovery in the fiber amplifier between pulses. The second approach relates to a cascaded optical amplifier system having at least two optical amplifying stages with two pulsed pump sources provided and two amplifying media, the first of which receives the injection and at least one pump signal wherein the injection pulsed signal is amplified to a first power and energy level. The second amplifying medium, optically coupled to the first, amplifies the first level signal to a second level amplified, injection pulsed signal. The duty cycle of the injection pulsed optical signal is synchronized with the first and second pulsed pump signals with the first pulsed pump signal having a different duration in the duty cycle than the second pulsed pump signal.
