IPC: B29C45/77
Filed: 1988-11-11
Abstract: In the production of mouldings from crosslinking moulding materials, in particular by the injection-moulding process, reproducible filling of the mould is problematical. Overfilling, with the consequence of flash formation, or underfilling, with the consequence that rejects are produced, frequently take place. In the case of the method proposed, the degree of mould filling is controlled with the aid of the pressures measured in the mould. The method makes use of the fact that crosslinking moulding materials are generally introduced into a mould which is of a higher temperature than the moulding material. After filling the mould, the moulding material is heated up in order to start the crosslinking reactions. The heating up causes a volume expansion. If the mould is completely filled, the expansion is prevented and a pressure increase occurs. If the mould is underfilled, expansion completely or partially takes place. The pressure increase is then less or there is no pressure increase. With suitable boundary conditions, these pressure signals characterise the mould filling level. The method provides mould filling control which acts from shot to shot. The reference variable for the control loop is the mould cavity pressure. The correcting variable for the control is, in the case of injection moulding, the metering stroke. In the case of other processes, the metering weight or the metering volume may be used. <IMAGE>

Abstract: Provided is an optical information recording medium and a method of recording information thereon. The information layer of the recording medium comprises an anthracyanine or phenanthra­cyanine chromophore compound. In a preferred embodiment, the chromophore is substituted with at least one substituent confer­ring film forming properties to the chromophore, e.g., a monomer or oligomeric substituent comprised of acid, amide or ester units. The resulting information layer exhibits strong absorp­tion in the range of from about 780-850 nm. Employing an anthracyanine or phenanthracyanine chromophore substituted with a film forming substituent further offers the advantages of a single component material exhibiting good thermomechanical properties.

Abstract: A central tire inflation system for a vehicle is disclosed 10 including a controller 222 for preselecting one of several desired air pressures for the tires 12 by actuating one of the push buttons 226, 228 or 230. The system 10 will adjust the tire pressure to the preselected pressure. Should the operator sense enemy fire or believes combat is eminent, the "run flat" button 234 is actuated which causes the electronic timer of the control unit 237 to cause the automatic measurement of tire pressure every few seconds instead of several times an hour. Should one of the tires 12 be damaged while the button 234 is actuated, the damaged tire will be immediately identified and the system 10 will assume the inflate mode and supply air to the damaged tire so long as the leakage rate does not exceed the capacity of the source 138 of pressurized air.

Abstract: The disclosure relates to a method and apparatus for manufacturing lenses including the use of a wafer in conjunction with liquid monomer to provide a molded plastic lens. In the molding process, a first mold form (14) is sealingly secured to a gasket (12) to form a part of a mold for receiving liquid monomer. The liquid monomer is poured into the first mold form and the wafer (33) material which can be tinted or have a different index of refraction is then placed in contiguous relationship with the liquid monomer. A second mold form (16) is then secured into the gasket (12) in sealing relationship therewith and spaced from the wafer to form a cavity (28) therebetween. Liquid monomer is then introduced into the cavity to fill all the voids. The mold with the material to be molded is then placed in the oven and cured. After the curing process is completed, the mold is removed and the formed lens extracted. An alternative includes the use of a mold form which is of the same material as the monomer such that it ultimately forms part of the lens. In this instance, the mold form is consumed during the molding process as it becomes bonded by intermolecular action with the liquid monomer.

Abstract: An arrangement providing a simple, rapid and flexible identification of the modules within a computer system during the initialization and identification phase subsequent to startup. A pre-defined, that is, previous to startup, configuration is implemented during initialization and identification phase without significant additional hardware costs. Each of up to 32 modules is connected to a different lead of a 32-bit wide parallel bus. During initialization, starting with the least significant bit position and progressing to the most significant bit position, one and only one position of the 32-bit parallel bus is driven to logic 1. The module exclusively connected to that bus bit position lead is selected to receive its pre-defined identification and configuration storage. Thus, when all modules have in turn been supplied with the initialization information, the next phase can begin.

Abstract: An optical body (20) having light reflecting properties is located in the luminaire housing (10) between the lamp (11) and the lower light outlet opening (12). The width of the optical body (20) is dimensioned such that the screening angle of the optical body - referred to the lamp (11) - is essentially equal to the free light emission of the luminaire housing. The optical body (20) consists of a compact block, the top side and underside of which each have at most one single concave break line. The direct radiation passing through the optical body (20) is deflected by refraction, in order to obtain suitable light distribution. Given precise maintenance of the desired directing of the light, the luminaire has high efficiency, because the reflections required for directing the light are limited to a minimum. <IMAGE>
