Patent CA-2197194-A1 (CA)
Inventor: MALCHESKY PAUL S
IPC: A61L2/28
Filed: 1995-08-16
Abstract: A pigment such as crystal violet is iatpregnated in or otherwise affixed to a translucent plastic or porous member (14, 22). The color change material changes at least one of opacity or color with repeated exposure to a fluid sterilant, such as an oxidant solution. A  label (10, 24) is mounted behind the translucent plastic material and carries an indicia (12, 26). With repeated sterilizafions of the instrument, the color change material becomes progressively more translucent, allowing the indicia to be read through the translucent plastic material. When the indicia becomes visible, such as after about 7 sterilization cycles in Figure 3, the user is warned to discontinue use of the instrument, either discarding it or having it rebuilt. Rather than having a written indicia, a color scale (30) can be provided for comparison against the current color of the color change material. When the color changes to the discard color on the color scale, the user is again advised to discontinue use of or rebuild the instrument.

Title: Supported metallocene complex and process for its preparation
Inventor: PROTO ANTONIO
IPC: C07F17/00
Filed: 1997-04-22
Abstract: A supported metallocene complex of a metal M selected from Ti, Zr or Hf, is prepared by a process comprising, in a first step, the reaction of an inorganic carrier containing hydroxyl groups with a compound (II) containing a cyclopentadienyl group and at least one alkoxysilane group reactive with said hydroxyl groups so as to chemically bind said cyclopentadienyl group to said carrier; and in a second step the reaction with a complex of said metal M capable of reacting with said supported cyclopentadienyl group without carrying out any intermediate metallation of the latter. This process is simple and convenient, and enables high concentrations of metal stably bound to the carrier, to be reached. The complex thus obtained can be used as solid component of a catalyst active in the polymerization of .alpha.-olefins, in the presence of a suitable co-catalyst, preferably consisting of an organo-oxygenated derivative of aluminum.

Title: One bit digital quadrature vector modulator
Inventor: VARELAS THEODORE
IPC: H03M3/02
Filed: 1997-08-15
Abstract: A One Bit Digital Quadrature Vector Modulator (DQVM) and a method of generating single sideband output signals are useful for a wide range of radio frequency, signal processing and wireless applications. The DQVM simplifies the necessary digital multiplication by using noise shaped one bit versions of  both the baseband I B and Q B signals to be modulated and the I LO and Q LO modulating signals. The one bit DQVM enables a much faster digital implementation of the digital quadrature vector modulation function than can be achieved with conventional multi-bit digital techniques. Digital vector modulators are an improvement over conventional analog vector modulators as they are not subject to the amplitude and phase matching problems inherent in analog vector modulators.

Title: Three stage self-regulating gerotor pump
Inventor: COZENS ERIC R
IPC: F04C15/06
Filed: 1995-08-14
Abstract: A gerotor pump is described for use with non-compressible fluids such as automotive coolant or hydraulic oil. The pump includes three separate pump outlet ports, a bypass return passage, and an integral four position spool valve. Increasing back pressure from a downstream load is sensed by the spool valve which moves accordingly to restrict the fluid supplied. In the first position a full flow fluid is supplied to the load from all three ports. In the second position one port is vented to the bypass and the flow from the other two ports is directed to the load. In the third position two ports vent to bypass, and one port drives the load. In the fourth position all ports vent to bypass. In each case flow vented to bypass is not first compressed, permitting a smaller motor to be used.
