Title: Graft polymers on carboxyl-containing polyurethane graft bases, process for their preparation, and their use
Inventor: KROGGEL MATTHIAS
IPC: C08F8/12
Filed: 1991-10-07
Abstract: Abstract of the disclosure:            Graft polymers on carboxyl-containing polyurethane graft bases, process for their preparation, and their use.            Carboxyl-containing graft polymers in which vinyl car-boxylates and, if desired, further ethylenically unsatur-ated monomers are grafted polymerically onto carboxyl-containing polyurethane graft bases by means of free radical-initiated graft polymerization, and hydrolysis products and salts of these carboxyl-containing graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and,  if desired, further ethylenically  unsaturated  polymerizable  and,  where appropriate, copolymerizable monomers onto a carboxyl-containing polyurethane graft base containing at least two urethane groups in the molecule,  in amounts of, preferably,  from 10 to 95 % by weight, based on the carboxyl-containing  graft  polymer,  by  free  radical-initiated  graft polymerization,  and  subsequently,  if desired, hydrolyzing all or some of the vinyl ester units and any other hydrolyzable monomer units in the grafted-on polymer radicals of the graft polymers using water and/or an alcohol, or converting the carboxyl groups into salts. Preferred vinyl esters to be grafted on are vinyl acetate and/or vinyl propionate and, if desired, vinyl versatate.    The graft polymerization is preferably carried out in solution or without a solvent.            Unhydrolyzed graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives, and, in their water-soluble or water-dispersible salt forms, as dispersants. Fully or partially hydrolyzed graft polymers are suitable, inter alia, for the production of films. Depending on the carboxyl group content of the polyur-ethane graft base, the degree of grafting, the degree of hydrolysis and the type of grafted monomers, the graft polymers  have  significantly  improved  solubilities  in aqueous-alkaline media and reduced melting points com-pared with polyvinyl alcohol, so that they are advantage-ously suitable for the production of pressed and extruded films  under mild temperature  conditions  without  the additional use of organic plasticizers. Hydrolyzed graft polymers  are  furthermore  suitable,  inter  alia,  as adhesives, as dispersants in aqueous-alkaline media and as sizes and textile lubricants in textile processing.
Patent CA-2055267-A1 (CA)
Inventor: MOREAU CHRISTIAN
IPC: H05H1/00
Filed: 1991-11-12
Abstract: A method and an apparatus for monitoring simultaneously the temperature and the velocity of sprayed particles.  The system is comprised of a sensor head attached to the spray gun, an optical fibre transmitting the collected radiation to detection apparatus, and a protective detection cabinet having the detection apparatus that incorporates two detectors.  A two-slit or multiple-slit mask is located in the sensor head at the end of the optical fibre.  For the temperature measurements, the particle emitted radiation collected by the sensor head is transmitted to two photodetectors, filtered by interference filters at two adjacent wavelengths.  The particle temperature may be computed from the ratio of the detector outputs.  To measure the velocity, the two-slit system collects radiation emitted by the in-flight particles travelling in the sensor field of view, which generates a double peak light pulse transmitted through the optical fibre. The time delay between these two peaks may be evaluated automatically and the particle velocity computed knowing the distance between the two slit images.

Title: Apparatus and method for overlaying data on trunked radio
Inventor: SHPANTZER ISAAC
IPC: H04W84/08
Filed: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE        A data communications system is overlaid on a voice-based trunked radio system.  Digital data packets are transmitted over available radio channels, thereby enabling data communication between a host dispatch system and mobiles and a base station in the trunked radio system.  Radio channels associated with trunked channel groups are accessed when available by a communications controller.  The communications controller is configured to communicate with various mobile units of the trunked radio system over available radio channels through multiple radio communication links.  Radio channels are monitored to detect when the radio channels are presently unused for voice transmission and thereby accessible for data overlay.  In particular, when the data overlay system detects that the transmission of analog voice information ceases over a particular radio channel, the trunked channel group association of that particular radio channel is caused to be switched from a voice group to a data group.  Data packets are then transferred over the available radio channel.

Title: Tie-wire for concrete form
Inventor: JOHNSON KEVIN M
IPC: E04G17/075
Filed: 1993-04-19
Abstract: Abstract In construction panels used during the pouring of concrete for housing or commercial foundations, it is known that metal tie-wires are used to secure the panels in their proper position once the panel latches are engaged into the latch engagement areas at either end of each tie-wire.          There is a natural tendency, due to expansion, for the panels to move to the outermost portion of the latch engagement areas when placing each set of panels.  In this invention, the panels are held temporarily in their proper position by a frangible clip that is part of the latch engagement area on each tie-wire.  Therefore, when the panel latches are hammered into the latch engagement areas, the frangible clips are displaced from the tie-wire by the panel latches and the panel latches then secure the panels in their proper position.  This saves the worker from having to force the panels inward each time a panel latch is secured to a tie-wire.
