Abstract: A cooling method using an adsorption agent is carried out in an apparatus including at least one reactor/adsorber embodied as a vessel for receiving the adsorption agent such as zeolite, at least one evaporator vessel receiving an evaporation agent such as water, and at least one line which connects the two vessels and which can be shut off with at least one shut-off member. The reactor/adsorber and the evaporator each have at least one orifice and are selectively connectable to a vacuum generator and to at least one condenser. The selective separation and connection of individual components and/or of component groups for carrying out regeneration and adsorption cycles take place in each case in a pressure-tight or vacuum-tight manner and with air being shut off.

Abstract: A method of fabricating a compound semiconductor device having an ohmic electrode of a low contact potential includes a first cleaning step of heating a compound semiconductor substrate containing a first conductivity type impurity in a temperature range of not more than 250° C. and etching its surface with hydrogen chloride at the temperature of not more than 250° C., and a second cleaning step of performing a radical hydrotreatment on the compound semiconductor substrate at a temperature not more than 250° C., after the first cleaning step. The first cleaning step removes an oxide film but leaves chlorine on the surface of the substrate. The second cleaning step removes the chlorine. The temperature of not more than 250° C. avoids damaging other layers such as an active layer on the opposite surface of the substrate.

Abstract: A hard carbon thin film formed on a substrate has a graded structure in which a ratio of sp2 to sp3 carbon-carbon bonding in the thin film decreases in its thickness direction from a thin film/substrate interface toward a surface of the thin film. A method of forming the thin film involves varying the film-forming ion species over time to produce the composition gradient or structural gradient in the thickness direction of the thin film.

Abstract: A diamond sintered body tool (20) having superior adhesion resistance, chipping resistance and high strength includes a tool base material (22) including a diamond sintered body, and a surface layer (21) formed on a surface of the tool base material (22). The surface layer (21) includes at least one of silicon, a silicon oxide, a silicon carbide, a silicon nitride and a solid solution thereof. The tool base material (22) has an inner portion (22b) including a first content of an iron group metal, and a surface portion (22a) surrounding the inner portion (22b ) and including a second content of the iron group metal lower than the first content.

Abstract: An angle of rotation of a camshaft relative to an angle of rotation of a crankshaft in internal combustion engines is adjusted for influencing the control times of a valve operation sequence. A wobble plate mechanism including a wobble drive realizes the adjustment. The wobble plate mechanism is arranged between camshaft and crankshaft, preferably between camshaft and a camshaft wheel.

Abstract: A control unit and two negative feedback branches limit the amplitudes of the output signal of an inverting differential amplifier. Each feedback branch includes a threshold value switch including a transistor as well as an adjustable current source and a resistor forming a voltage divider between a supply voltage and the amplifier output. The voltage divider output is connected to the transistor's base. The transistor selectively connects or disconnects the input of the amplifier with either the supply voltage or the amplifier output. The control unit controls the two current sources based on external programming commands, to establish two adjustable threshold values within which the negative and positive amplitudes of the output signal are limited, symmetrically or independently, in a hard or soft clipping manner. Even with small supply voltages, the limited output will not overdrive subsequent amplifier input stages and will not superimpose harmonics on the useful signal.

Abstract: A combined tool for edge-folding and trimming a rim of a panel includes a cutting blade rigidly secured to a tool holder frame, an edge-folding tool slidably received in the tool holder frame, and a biasing spring arranged in the tool holder frame to bias the edge-folding tool outwardly away from the holder frame. The tool is moved in a linear stamping direction, whereby the edge-folding tool folds back and then holds and compresses a margin of a panel workpiece. The tool holder frame and cutting blade are pushed farther in the linear stamping direction, while the edge-folding tool is pushed back into the tool holder frame and compresses the biasing spring, whereby the cutting blade cuts through and compresses the panel workpiece. This forms a back-folded, compressed, and trimmed rim of the finished panel in a single work step using an integrated edge-folding and cutting tool.

Abstract: A trim component (1) includes a substrate (2) and two different cover materials (3, 4), which are not spliced together but are independently adhesively bonded onto the substrate (2) by a hot-melt contact adhesion. The junction (7) is received in a valley (6) of the substrate that is pinched closed using a molding apparatus that includes a horizontally movable pinching stamp (13) which forms a pinching gap (16) relative to a protruding edge (11A) of a fixed mold tool (11). A tucking blade (22) cooperates with a counter-clamping blade (26) to clampingly hold and then press the substrate and junction of the cover sheets into the pinching gap. The tucking blade is then retracted while the pinching stamp pinches closed the pinching gap, to form a tightly closed valley in the substrate with the junction cleanly pinched therein.

Abstract: A recovery craft with a coupling arrangement captures, engages, and transports a defective or expended non-maneuverable spacecraft. The coupling arrangement includes a coupling mast (e.g. a telescoping pipe), a releasable rigid mount that secures one end of the coupling mast to the recovery craft, and spreader arms that are radially spreadable from the other end of the coupling mast. The spreader arms are initially radially inwardly retracted, and are inserted into an interface ring of the spacecraft. Then the spreader arms are radially outwardly extended to engage behind a protruding rim of the interface ring. A spring braces against the spacecraft. Next, the rigid mount is released and the coupling mast remains connected to the recovery craft only by a tension-transmitting cable. Thrusters of the recovery craft are activated to tow the spacecraft to a new target position, orbit, or trajectory.

Abstract: A female crimp terminal includes a tubular body, a leaf spring contact inside the body and integrally extending from the front part of the body, a neck having a U shape when seen in the longitudinal direction and integrally extending from the lower parts of both side walls and the bottom wall at the rear end of the body, and a barrel having a U shape when seen in the longitudinal direction, integrally extending from the neck and having retainers extending upward high above the neck. A notch is made in a rear edge of each side wall from the rear end of the body so as to divide the side wall into an upper part and a lower part. This isolates crimping forces of the barrel from the tubular body which houses the leaf spring contact.

Abstract: A composite laminate or layer structure includes a substrate (2) and a cover layer (4) bonded thereon. The substrate is made up of at least one layer (3) of fiber-reinforced synthetic material. The cover layer includes at least one layer (5) of metal fibers and/or threads (6), and a metal sheet (7) forming the outer surface skin (8) of the layer structure. The metal sheet is bonded by soldering or sintering onto the metal fibers and/or threads (6), while the layer of metal fibers and/or threads in turn is bonded to the underlying fiber-reinforced synthetic material (3) by being mutually and integrally permeated by a synthetic resin matrix and bonding material. Also, the metal fibers and/or threads (6) may be intermeshed with the fibers of the synthetic material (3).

Abstract: A child seat includes a seat body, a base, and a mechanism for simultaneously sliding the seat body forward as the seat body is rotated relative to the base. This rotation sliding mechanism includes a cam plate connected to the seat body and an abutting plate connected to the base. When the seat body is in a forward-facing position, one side of the cam plate is entirely abutted against the abutting plate. When the cam plate is rotated by 45°, the cam plate moves toward the front while a corner of the cam plate abuts against the abutting plate. With this structure, the child seat has enhanced securing stability relative to a vehicle seat and can facilitate in-vehicle handling.

Abstract: For producing a structural component of fiber-reinforced material by a resin transfer molding process, a preform unit is inserted in a form tool including upper and lower metal molds enclosing the perform unit therebetween, without a seal between the molds. The preform unit includes a resin-impregnatable and curable preform body of reinforcing fibers, and an envelope that encloses the preform body and includes an envelope sleeve and closures with valves at the two ends thereof. The sealed envelope is evacuated around the preform body through one valve, and resin is injected through the other valve. The envelope prevents resin discharge from the unsealed form tool during resin impregnation of the preform body.

Abstract: A device for controlling the driving movements of a tracked vehicle includes a control lever 2 which can pivot about at least one pin 3, and a magnet arrangement by which any manually established position of the control lever 2 can be magnetically fixed. The strength of the magnetic fixing force is selected so that the control lever can be manually moved to a new position while overcoming the magnetic fixing force, and then the control lever is again magnetically held at the new position.

Abstract: A double-walled pipe connection for an aircraft fuel line includes a first outer pipe surrounding a first inner pipe, a second outer pipe surrounding a second inner pipe, a pipe coupling joining the inner pipes together, a securing fixture on the first inner pipe, a sleeve-shaped outer pipe bushing bolted to the securing fixture by bolts oriented parallel to a radial direction, and an outer pipe sleeve that is axially slidable over the second outer pipe and onto the outer pipe bushing. The first outer pipe is plugged into the outer pipe bushing, which is plugged into the outer pipe sleeve, which seals onto the second outer pipe. The inner pipe coupling is covered or exposed by axially moving the outer pipe sleeve, while the outer pipe bushing remains bolted to the first inner pipe, and mechanically secured and electrically grounded to a metal structure.

Abstract: The invention relates to a method and an apparatus for the mass simulation of vehicle masses on a stationary roller test stand, wherein the simulation mass (msim) is determined from the test stand mass (mP) and from the mass (mRad h?) of the non-driven rotatable vehicle parts that are determined by measuring techniques, as well as from the mass (mRad h?) of the driven rotatable vehicle parts that are determined by measuring techniques, and with the aid of the translatory vehicle mass (mF), in an evaluating device (10) of the test stand.

Abstract: Harmful trailing vortices downstream of an aircraft wing are at least partly dissipated by a respective counteracting vortex for each trailing vortex at each wing. An auxiliary counteracting vortex generating flap, preferably in the form of at least part of a delta wing, is journaled to the respective wing in the area of the outer end of a landing flap. The counteracting vortex is imposed on the respective trailing vortex, whereby the trailing vortex is caused to vibrate. The vibration dissipates the trailing vortex at least partially.

Abstract: A T nut has a cap portion 45 integrally formed continuous from a tip end portion of a flarable portion 34. At a connecting region between flarable portion 34 and cap portion 45, an inner surface 44 of flarable portion 34 is formed recessed outward. With this structure, the T nut can be driven cleanly directly into a solid workpiece object, without the necessity of providing a receiving hole in advance. Also with this structure, a caulking force applied by a caulking counter tool to the tip end portion of the T nut separates the cap portion from the flarable portion and outwardly caulks and flares the flarable portion to secure the T nut to the workpiece.

Abstract: Thermoplastic products such as vehicle cargo area liners, floor mats, recreational and playground equipment, cargo pallets, and wet area walking surfaces are provided with an antislip surface treatment. The antislip surface is made up of individual non-interconnected asperities of an antislip polymer material, which do not form a continuous film over the surface of the thermoplastic product. The thermoplastic product is especially made of high density polyethylene. The antislip polymer is preferably a thermoset polymer, and most particularly is a polyurea/isocyanate polymer. The antislip polymer is preferably applied by spraying, and then the product is heat treated at a temperature in the range from 100 to 200° F., or is thermoformed at a temperature in the range from 250 to 550° F. The antislip asperities are durably bonded onto the thermoplastic base material, and provide a significantly increased coefficient of friction.
