Title: Laser alignment system for small arms
Inventor: PARIKH HIMANSHU N
IPC: F41A33/02
Filed: 1995-04-28
Abstract: An electro-mechanical fixture automatically aligns a laser transmitter bolte d to the stock of a rifle for subsequent use by a solder in war games. A recta ngular hollow case is horizontally oriented and a hinged end cover is swung upwardl y toreveal an LCD display and keypad of a control unit. A sliding rack is extended horizontally from a base unit inside the case. The barrel of the rifle is su pported on a weapon rest mounted to the base unit and the trigger guard or clip rece ptacle is mounted in a vise on the rack. The vise has knobs for adjusting the azimu th and elevation of the weapon, thereby permitting the soldier to aim at an ima ge of a target reticle. An optics unit is mounted on a forward portion of the base  unit and includes a lens and a beam splitter which is transparent to infrared lig ht from the laser transmitter but reflective to visible light. The illuminated targe t reticle is mounted inside the optics unit below the axis of the laser beam. The beam sp litter is positioned forward of the lens and is angled at forty-five degrees to pro ject the image of the target reticle through the lens at infinity. A position sensor detector in the optics unit receives the laser beam and generates an error signal representative of a displacement between a received location of the laser be am and the image of the target reticle. A circuit in the control unit is connected to an alignment head which is mechanically coupled with a rear end of the laser transmitter bolted to the rifle. The circuit causes the alignment head to re petitively trigger the laser in the laser transmitter. Utilizing the error signal, the circuit causes the alignment head to independently rotate wedge prisms in the laser transmitter to steer the laser beam in azimuth and elevation until the laser  beam is substantially aligned with a boresight of the weapon.
Patent CA-2193032-A1 (CA)
Inventor: HEINEMANN TORSTEN
IPC: C08F290/06
Filed: 1996-12-16
Abstract: A process is described for the production of stable agglomerate-free low-viscosity polymer polyols by free-radical polymerization of ethylenically unsaturated monomers, such as styrene and/or acrylonitrile, with polyol compounds. This process requires that prior to the start of the free-radical polymerization, an olefinically unsaturated compound which is capable of reacting with primary hydroxyl groups is added to a base polyol which contains at least 2 wt-% of a polyol containing primary hydroxyl end groups, and then, the free-radical polymerization is carried out. Suitable olefinically unsaturated compounds include unsaturated cyclic or acyclic anhydrides, unsaturated acid chlorides and/or unsaturated epoxides. Also, a process for the production of polyurethane plastics from the polyisocyanate polyaddition process is described wherein the isocyanate-reactive component comprises the polymer polyols produced from the above described process.

Title: Mechanical set anchor with slips pocket
Inventor: HEBERT JOSEPH V
IPC: E21B7/06
Filed: 1997-01-30
Abstract: A mechanical set anchor wherein a plunger extending from a base end of an anchor body activates a pin type trigger which releases a spring utilized to set multiple slips extending from the body of the anchor. Continued downward compressive forces fully sets the slips into the borehole pipe casing. The slips are maintained in their fully set position by a locking nut. Means are additionally provided to further set the slips into the pipe casing after slips are released from the anchor body. The anchor is mechanically released by an upward pull under tension of sufficient strength to shear release pins that release the compressed spring fully retracting the slips within the anchor body so that the anchor may be tripped from the borehole without interference from the previously engaged slips.

Title: Optical nxn wavelength crossconnect
Inventor: OEBERG MAGNUS GUNNAR
IPC: H04B10/27
Filed: 1995-09-26
Abstract: The present invention relates to optical coupling systems which include optical NxN wavelength cross-connectors where N is the number of inputs and outputs. The wavelength cross-connectors are used to connect together different nodes in the coupling system and are comprised of two different passive components: optical circulators and fibre gratings. A 2x2 wavelength cross-connector (OXC1) is formed by two circulators (C1, C2) which are connected together through the medium of a fibre grating (B1) connected to the intermediate ports of the circulators. To construct a 4x4 wavelength crossconnector (OXC), there is then used two 2x2 wavelength cross-connectors (OXC1, OXC2), wherein the outputs of the 2x2 wavelength cross-connectors are connected together in pairs by means of circulator-pairs (C5-C6, C7-C8) and a fibre grating (B3, B4). The fibre gratings (B1-B4) reflect certain of the wavelength channels (1; 1, 3; 1, 2; and 1, 4 respectively) in the input signals delivered to the inputs a-d and transmit remaining wavelength channels, thereby enabling each node to communicate with each other node. This enables wavelenth cross-connectors having N inputs and N outputs to be builtup. The cross-connection schedule in Figure 3b shows which wavelength channel shall be used to transmit from one node (A, B, C, D) to another node.

Inventor: ARTS GENE
IPC: A61B18/14
Filed: 1995-11-08
Abstract: A partially coated electrosurgical electrode has a portion of a medical grade metallic material as a substrate for energy application. Conductive sites of metallic material or alloys thereof pass energy through peaks that define valleys nearby. A partial coating in the valleys has a low surface free energy. A treated surface across the peaks and generally over the filled valleys is relatively smooth for non stick characteristics during application of electrosurgery to tissue and bodily fluids. Openings in the treated surface through the partial coating are at the peaks of conductive sites to expose the metallic material or alloys thereof. The partial coating is a fluorinated polymer. The treated surface is a relatively even level that is not flat. The metallic material substrate is an alloy of stainless steel or nickel chrome. A  mechanically deformed surface finish, plasma or vapor deposition on the substrate forms the conductive sites. A method of manufacturing the electrode has steps including preparing the metallic conductor, making it with the conductive material having peaks above the valleys as conductive sites, applying the partial coating to it and treating the surface across the peaks and generally over the filled valleys of the partially coated electrically conductive electrode. Locating the openings among the valleys is a step.  Treating may be mass finishing, such as vibratory or tumbling the partially coated electrodes with or without abrasive material media or polishing, buffing, surface grinding, abrasive belt grinding or sanding with abrasive material. Making the peaks and valleys can be by stamping, coining, burnishing, embossing, threading, tumbling, vibrating, shot peening, wire brushing, grit blasting, thermal spraying, with powder, with wire supplied to melt and be distributed, or with high velocity oxygen fuel and a nickel, cobalt alloy, stainless steel or a nickel chrome alloy. A manufacturing method for the electrode has coating a strip of metal with the low surface energy polymer and forming it in a stamping operation with a raw metal edge.

Title: Process for hydrophilicization of hydrophobic polymers
Inventor: DING NI
IPC: C08J7/056
Filed: 1996-01-15
Abstract: A process for rendering the surfaces of polymeric plastic or rubber materials, which are intrinsically non-polar or only slightly polar, and hydrophobic, polar or more polar, and hydrophilic, so that amine-containing functional groups, and ultimately, a durable tenaciously adhering, slippery polyurethane or polyurethane-urea hydrogel coating may subsequently be applied to the polymer surface, is disclosed.  The process involves dual plasma-treatment of a polymeric plastic or rubber substrate material; the first treatment being with an oxygen-containing plasma gas, to affix hydroxyl, carboxyl and carbonyl groups to the substrate surface, thereby rendering the surface more polar and activated; and the second treatment being with a nitrogen-containing plasma gas, to affix amine and amino groups to the substrate surface to make it more hydrophilic and reactive toward terminal isocyanate groups of a polyurethane or polyurethane/urea prepolymer adduct intermediate tie-coat which is subsequently applied to the substrate surface and then converted to a tenaciously adhering, slippery hydrogel coating. The process is especially suited to the hydrophilicization of intrinsically non-polar and hydrophobic polymeric plastic materials, such as polyethylenes, nylons-11 and nylons-12.
