摘要:
There is provided a block, segmented or graft copolymer having polyorganosiloxane segments and self-associating hard segments, which copolymer is capable of forming a solid, generally non-tacky release coating without the requirement of curing. The release coating comprises the polyorganosiloxane copolymer admixed with an MQ resin wherein the amount of MQ resin is generally between 1 and 30 weight percent of the polyorganosiloxane content preferably 1 to 20 weight percent. The MQ resin modifies the copolymer release material to have a higher release than the copolymer itself, generally at least 10 percent and preferable at least 20 percent up to 50 percent or higher with the readhesion values decreasing by 50 percent or less, preferably 40 percent or less.
摘要:
An intermeshable electrical connector comprises a flexible electrically conductive member having electrically conductive elements along an outer surface for forming electrical connections with a rigid member having electrically conductive elements along an outer surface, these elements being correspondingly configured to the elements on the flexible member. The rigid member may be intermeshed with the flexible member at a desired location in a releasable engagement, forming the electrical connections, while allowing for subsequent release and reconnection without stripping, damaging or penetrating the electrically conductive elements of the flexible member.

摘要:
A method for the production of poly(vinyl trifluoroacetate) and copolymers thereof with vinyl esters is described. Poly(vinyl trifluoroacetate) (PVTFA) is obtained in essentially quantitative yield under mild conditions by using non-chlorofluorocarbon solvents comprising siloxanes or perfluorinated fluid. Hexamethyl disiloxane is a particularly useful example of such solvents. Synthesis of syndiotactic PVTFA on a commercial scale without the use of environmentally-harmful solvents is made possible by the invention, which provides a convenient commercial route to syndiotactic polyvinyl alcohol.
摘要:
An apparatus for locating obscured conduits, such as buried cables, employs a novel signal processing technique to increase the sensitivity of the apparatus, particularly in congested areas. The cable locating apparatus is similar to prior art dual-peak detection devices which compare signals from two parallel induction coils, but a phase shift is introduced into one of the signals prior to the comparison. This phase shift serves to minimize the effects of side minima in the response curve of prior art dual-peak devices. This effect is enhanced by adding a gain mismatch to the two detected signals. The locator preferably operates with analog signals to reduce expense.
摘要:
A detector for detecting electrostatic discharge events in an electronic component, assembly or system and including a display element which produces an immediate indication on exposure to a change in voltage level, an electrostatic discharge sensor, and circuit means for connecting said sensor to said display element. In one embodiment, the detector and the board or other device to be monitored are mounted in a housing having a visual access window with the display element of the detector viewable through the access window and with the detector positioned at the electronic device being monitored.
摘要:
The present invention provides a discontinuous metal/polymer composite, with a metal layer, formed from a plurality of fine metal strands, which may be used, for example, in static or EMI shielding. The metal layer comprises a plurality of fine metal strands provided on the substrate, the metal strands individually having a cross-section with an area of about 100 to 100,000 .mu.m.sup.2 and the cross-section of the individual metal strands having a flat portion and an arcuate portion. The metal and polymer may be selected so that the composite is capable of being thermoformed without loss of electrical conductivity or transparency.
摘要:
This invention provides improved prosthetic devices for the replacement of a ligament or a tendon. The tension borne by the prosthetic ligament or tendon can be readily increased or decreased without disturbing the attachment of the device to bone and without removal of the prosthetic ligament or tendon from the other components of the device.
摘要:
A continuous horizontal road-marking tape is described. The road-marking tape includes Light Emitting Diodes (LEDs) or high intensity microlamps, solar cells and retroreflecting elements. The LEDs may be double and focused for better visibility, their light is pulsing at a regular speed or at an emergency fast speed. The road-marking tape balances the solar energy captured by its solar cells with the emitted light employed to signal or warn motorists. Also described is the use of an emergency fast pulsing for signalling an emergency or the presence of ice, and the use of the tape for controlling situations where a single lane of roadway must alternatively pass traffic from two different directions. Activation of the light emitting sources is by sensing light from headlights of oncoming cars or by traffic lights.
