Abstract: A microwaveable exercise putty includes a borosiloxane or stannosiloxane reaction product. The resulting reaction product is mixed with a second polysiloxane, an internal lubricant such a monounsaturated fatty acid, and a particulate material which creates heating upon subjection to microwave energy. Precipitated silica is a particularly preferred particulate material. The exercise putty may be manipulated by patients, and at the same time is capable of delivering heat to the body part undergoing the manipulation.

Abstract: A process for mounting of an optical fiber (1) on a substrate (2) and for optical coupling between this fiber and an optical or optoelectronic element (17) or component such as a waveguide, a receiver or an emitter formed or carried on the front face (5) by the substrate, consisting in inserting the end of an optical fiber (1) into a through orifice (6) formed in the substrate (2) engaging it by the rear face of the substrate, in sealing the end of the optical fiber in said orifice, and in forming on the path of the optical wave a deflecting facet (18) such that the optical wave originating from the optical fiber is deflected by this facet towards said element or component (17), or vice versa.
Abstract: An improved drive head for use in transporting materials has a frame for mounting near a tubing orifice, a drive wheel and second wheel rotatably mounted on the frame. Each of the wheels are adaptable to receive a fluid entraining conveyor. The drive head causes the conveyor to move through a predetermined conveyor path on which the conveyor winds about the drive wheel through at least a majority of its surface, and preferably 330.degree.. The radius of a down-conveyor conveyor track of the second wheel is preferably slightly greater than the radius of the drive wheel conveyor track. Preferably, tires are provided which are mounted on wheel hubs of the drive and second wheels, and these tires may be made of an elastomer having a higher coefficient of friction than the preferably plastic drive and second wheel hubs. The preferred embodiment includes a third wheel which is disposed on the conveyor path to be closer to the orifice than the second wheel.

Abstract: Apparatus (10, 50) for removing frozen water from vehicle glass includes a cured, microwave-heatable layer (14, 64). The microwave-heatable layer (14, 64) may be formed from at least one elastomeric gum, a curing catalyst adaptable to cure the gum, and microwave-heatable particulate matter dispersed in the gum. In one embodiment, the apparatus (10) is a mitt including an insulative layer (42) which is positioned to be interposed between an inner surface (27) of the elastomeric pad (14) and the hand, such that the hand does not undergo temperature stress. The mitt (10) also preferably includes a visual marker (30) to indicate the temperature of the elastomeric pad (14).
Abstract: An improved wiper blade of the type used on a vehicle windshield having an indicator means painted on the wiper blade which indicates that the wiper blade should be replaced. The exposure to UV light of the indicator painted on the wiper blade causes it to change in color and thus communicate to the user that it is time to change. The indicator paint is a silicone resin paint and would be applied to a wiper blade made of a resilient elastomeric material which is degraded with exposure to UV light in the atmosphere.
Abstract: A windshield wiper blade capable of inexpensive manufacture and having good wipe quality comprises approximately 100 parts by weight of a vulcanizable elastomer including at least one silicone polymer, and about 75 to 220 parts by weight of a siliceous filler dispersed in the elastomer. The siliceous filler preferably includes a substantial portion of particles having a relatively large diameter in the range of 5 to 100 microns in order to lower the coefficient of friction of the wiper blade with respect to automotive windshield glass.
Abstract: A mobile modular foam fire suppression apparatus includes a movable platform. Supplies of foam concentrate and water are remote from the platform. A foam concentrate pump mounted on the platform pumps foam concentrate from a remote supply, such as a foam concentrate tank or tailer, to a water/foam proportioner on the platform. Water is provided under pressure from sources such as pumper trucks to a water inlet of the water/foam proportioner. The proportioner mixes the water and the foam concentrate to form a foam solution, which may then be applied to a fire with any of several foam solution discharge devices. Preferably, the apparatus also includes a foam concentrate return line which returns excess foam concentrate back to the remote supply of foam concentrate. This return line has a pressure regulator which regulates the pressure in a portion of the foam concentrate return line to a predetermined value.
Abstract: A method for facilitating call completions utilizing a call identification telephone number which is transmitted along with an incoming call. A user of the call processor of the invention can program a list of anticipated or preferred call identification telephone numbers, together with destinations to which it is desired to route the respective incoming calls. During an incoming call, the call processor matches the associated call identification telephone number with a preprogrammed number and thereby completes the call according to the programmed destination.
Abstract: A time slot interchange matrix is comprised of a plurality of matrix modules (50-56) each for receiving data on a plurality of channels and transmitting data on the same number of channels. Each of the modules consists of separate banks of random access memory that are interfaced with an intramatrix bus (70) for receiving data from each of the matrix modules in the system for storage therein during a collection frame. During a transmission frame, this information is randomly accessed in accordance with an interconnect pattern stored in a control RAM (122) for output from the digital matrix module. Each digital matrix module stores all of the information in the system such that the system is non-blocking for any given channel stored such that information is not impeded by the interconnect pattern of another digital matrix module. A digital bridge (80) is provided for collecting the information during a collection frame and then accumulating the information in a bridge IC circuit (137) as a conference.

Application of heat along seams (24) and (26) attach the ear loops (14) and (16) thereto in addition to securing the ends of the pleats (18-22). In this manner, internal fibers of the layer (12) are restrained from entering the surrounding environment.
Abstract: An arterial wrist support for supporting a patient's extremity for arterial or intravenous care includes a substantial rigid, unitary molded body (12) adapted to matingly engage the patient's hand, wrist and at least a portion of the patient's forearm. Body (12) is anatomically shaped to accommodate the contours of the patient's arm and to position the patient's wrist at the proper angle to expose the radial artery for accurate, efficient handling of the arterial puncture.
