Abstract: A process for making a smooth perforated contoured resilient panel of a type suitable for use as a decorative headliner in the passenger compartment of vehicles or the like. A thermoplastic composite laminar sheet comprising a pair of films tenaciously bonded to the opposed faces of an intervening thermoplastic foam core having closed cells containing air and residual blowing agent is perforated in flat sheet form whereafter it is heated to an elevated temperature to effect heat softening and expansion of the foam core resulting in localized dimpled recesses in the faces adjacent to the apertures or perforations. The heated expanded sheet is thereafter thermoformed between appropriately contoured mold surfaces to effect a contouring and compaction of the sheet to a thickness substantially equal to or less than the thickness of the dimpled or recessed sections forming a contoured sheet having substantially smooth exterior surfaces. The compacted and contoured smooth sheet thereafter is cooled to effect rigidification and retention of the contoured configuration thereof. The process further contemplates the application of a decorative layer to the sheet prior to or subsequent to the heating and molding operation.

Abstract: A magnetic tape drive system for a video cassette recorder comprises a flip-over magnetic tape cassette having side-by-side reel hubs, each hub having a disc-shaped centering and drive member in the center of the hub with a central centering aperture and one or more drive apertures at some radial distance from the centering aperture, and a drive arrangement with drive spindles having a centering pin for the centering aperture in the reel hub, and at least one resiliently depressable drive pin which engages a drive aperture. To ensure correct positioning and drive of the spools and an excellent lace-up, and prevent undesired variations in the tensile stress in the magnetic tape and thus variations of the stretch of the magnetic tape, the reel hubs are resiliently urged onto stop surface which rotate with the drive spindles. The resilient urging devices and drive apertures are arranged to prevent disturbing forces on the reel hub.

Abstract: 2<n> memory locations M are addressed via logical operations between binary short addresses sha with k < n bits and base addresses, each of which defines a number of memory locations comprising memory segments and each of which constitutes the lowest of consecutively increasing binary memory addresses ma with n bits, by means of which the memory locations of the particular segment are addressed. The short addresses are divided into groups of consecutively increasing short addresses. The groups are each defined by their own k-bit group address, which is stored in buffer memory. Periodically designated memory segments and corresponding base addresses are each associated with at least one short address group, which comprises at least identical numbers of short addresses as the particular segment contains memory locations. The address differences D1 ... D4 of the designated base addresses in relation to each lowest address within the groups of associated short addresses are saved in buffer memory. To expand a short address into a memory address, a selection signal ss1 ... ss5 is generated by means of said group addresses, which indicates the group that includes the short address. Furthermore, a n-bit sum address is generated, which constitutes the memory address, by adding the short address to the address difference pertaining to the group of short addresses indicated by the selection signal. <IMAGE>

Abstract: A blade for a fluid flow engine, especially a gas turbine, has a protective coating against injurious attack by the propellant or working medium. A metal blade having a diffusion layer or a sprayed coating for inhibiting corrosion is known. Such coating renders the blade highly resistant against heavily erosive and corrosive attack, especially by pulverized coal combustion gas or similar agents. The present blade is made of ceramic material, especially a dense ceramic material with a surface layer of at least one of the following materials: TiN, TiC, B4C, BN and titanium carbon nitride. These materials are easy to apply and provide a good bond with the ceramic material. If the ceramic materials are silicon carbide (SiC) or silicon nitride (Si3N4) an especially good bond is achieved. This coating strongly resists removal, as it does oxidation and heat. Local removal down to the ceramic material, as it may result from rather long service, is recognizable immediately. These coating materials can be applied to give adequate quality and satisfactory repeatability by using the known CVD (chemically vapor deposited) or the PVD (physical vapor deposited) process.

Abstract: The present specification discloses an apparatus for washing a rubber blanket cylinder of a printing machine. The apparatus comprises a cleaning cloth which extends between a supply roll and a take-up roll, with control and drive means adapted to rotate the take-up roll in a step-wise manner to thus take up uniform lengths of cleaning cloth. A rotatable guide roller is arranged to press the cleaning cloth between said rolls, against the rubber blanket cylinder, the rotatatable guide roller having a resiliently deformable outer surface across which the cleaning cloth is guided. A reversible brush roller is located upstream of the rotatable guide roller in the direction of rotation of the rubber blanket cylinder, and is in contact with said cylinder, and a cleaning agent supply and a water supply are arranged to feed said brush roller. Said control and drive means comprises a crank which acts upon a lever via a connecting rod, said lever being connected to a take-up shaft, in which the take-up roll is mounted, by way of a one-way clutch. The point at which the connecting rod acts upon said lever is variable dependent upon the quantity of cleaning cloth taken up by said take-up roll. The width of the cleaning cloth corresponds only to a portion of the length of the cylinder, and guide and operating means are provided for moving the apparatus transversely along the entire length of the cylinder.

Abstract: A semi-conducting structure delimits two quantal wells (CP1, CP2) connected across a barrier layer (CB). The application of an electric field to the structure makes possible the transfer of electrons from one of the wells to the other. The electron-hole pairs are created by a wave-pump, or by the doping of one of the wells. This makes possible, in particular, a dual control by means of the wave-pump and the electric field, thus creating an "AND"-function modulator.
