Abstract: A vehicle air compressor apparatus is provided for a heavy vehicle air braking system. The apparatus comprises a crankcase, and a cylinder head disposed on the crankcase. The cylinder head includes (i) an air inlet port through which air can be received for compression within the crankcase and the cylinder head, (ii) a discharge port through which compressed air can be delivered from the cylinder head, (iii) a first port through which compressed air can pass, and (iv) a second port through which cooled compressed air can pass. The apparatus further comprises a discharge air cooling jumper connected externally of the cylinder head between the first and second ports. The jumper is arranged to cool compressed air passing from the first port through a discharge air path of the jumper to the second port to provide cooler compressed air to be delivered from the cylinder head through the discharge port.

Abstract: In one embodiment, a system to compensate for misalignment between a drive shaft and a driven shaft includes a coupling device secured to the driven shaft, a bore in the drive shaft for receiving the coupling device, and a securing device to fasten the coupling device in the bore while permitting lateral movement of the coupling device within the bore to compensate for misalignment between the drive shaft and the driven shaft.

Abstract: An inlet control device includes a status valve and a reed valve. The status valve is positioned as a function of a status of a state of a compressor. Also, the reed valve delivers a reed output pressure to an inlet of the compressor as a function of a reed input pressure on an input side of the reed valve, the position of the status valve, and a rotational speed of the compressor.

Abstract: A new holder (1) for a disk-shaped information carrier, in particular for a compact disk, is described with a base support (2;21) and clamping elements (3; 17) arranged thereon and integrated therewith which extend into the central opening of the information carrier. The clamping elements (3; 17) in this arrangement are arranged surrounding a central support member (11; 18) and the clamping elements (3; 17) and support element (11; 18) are not higher than twice the thickness of the disk-shaped information carrier. Furthermore a plate-shaped support member (15) for a disk-shaped information carrier, in particular for a compact disk (32), is described which presents a recess in which a holder (1) is arranged which penetrates a central opening of the information carrier (32) detachably connecting the latter to the support member (15).

Abstract: Injection device for injecting fluid from a fluid container equipped with a piston, comprising an actuating device having a rod-shaped driven member having a structured surface, a control button being movable in axial direction, and a hollow cylindrical counter component having a structured internal sleeve, said counter component matching the rod-shaped driven member and being coaxially arranged in relation to said driven member.

Abstract: Modified polyurethanes containing perfluoroaliphatic groups which are obtained by reacting oligo(poly)urethanes containing free hydroxyl or isocyanate groups and perfluoroaliphatic groups with di/polyfunctional polysiloxanes at elevated temperatures with conversion of all the reactive groups of the urethane are used for the oil- and water-repellent finishing of fiber materials, conferring on these materials thus treated not only laundering- and drycleaning-stable effects but also in particular a very soft, full hand of very good surface smoothness, these excellent hand effects being further optimized by the addition of a polyethylene dispersion and/or of further customary textile assistants, in particular water-repellent fluorocarbon compounds.

Abstract: An aqueous finishing agent for providing fibrous materials with a soft water and oil repellent treatment is provided. The finishing agent comprisesA) 25 to 65% by weight of a perfluoroaliphatic group-bearing water/oil-repellent agent (at least 5% by weight fluorine) in dispersion,B) 10 to 35% by weight of a dispersion of an emulsifiable polyethylene (density at 20.degree. C. at least 0.92 g/cm.sup.3, acid number at least 5) andC) 25 to 40% by weight of a fluorine-free dispersion of a soft-hand extender based on a modified hydrogen alkyl polysiloxane. A process for providing fibrous materials with a soft water and oil repellent treatment is also provided. The finishing agent provides fibrous material with excellent properties which are resistant to washing and dry cleaning and a particularly smooth, soft hand.

Abstract: A closed-cycle breathing equipment and gas mask for operation under pressure with a pressurized air source for respiratory air and with an air bag being under prestress during the inspiration phase includes an arrangement where the prestress is decreased by a control element recognizing the expiratory phase and so as to support respiration during the expiration phase. A pneumatic control valve is used which can switch connections between the inspiration and the expiration phase and which is directly controlled by the difference between the exhalation pressure and the pressure in the air bag. The control valve connects the pressurized air source with the air bag during the inspiration phase and during the expiration phase it interrupts the connection due to the occurring dynamic pressure of the pressurized air from the pressurized air source and thus actuates a pneumatic adjusting element so that the mechanical prestress at the air bag is reduced.

Abstract: A chemical oxygen generator has a chemical mixture based on an alkali-metal chlorate (NaClO.sub.3) which constitutes the charge of a cartridge having an ignition device and an oxygen outlet. This oxygen generator is improved so that the charge is insensitive to shock and so that it can be configured in any desired outer form and size and that an advancing reaction zone is assured without a further assisting device. The charge includes a tight bed of chemical pellets which lie one against the other to form the smallest possible contact surfaces.

Abstract: A disc brake assembly (10) includes a rotor (12) having a pair of friction faces (14, 16) and a pair of friction elements (18, 20) disposed adjacent the friction faces. A caliper (32) is slidably mounted on a support member (22) by mounting mechanism (40). Mounting mechanism (40) includes a camming member (66) supported by the support member (22) and slidably engaged by the caliper (32) and a torsion spring (82) which yieldably rotates the camming member (66) into camming engagement with the caliper (32) and support member (22).

Abstract: A circuit is described which makes use of a mathematical transformation based solely on AND and OR connections for the purpose of recognizing patterns, and a process for localizing this pattern within a zone or range. By means of the direct connection of AND and OR gates, a completely parallel processing of each individual bit is achieved in the arithmetic and logic unit so implemented, which signifies a fraction of the processing time as compared to full adders. Simultaneously the equipment is capable of recognizing a specific pattern (object) from a multitude of mutually nested structures (neighborhood) and to localize it by a subsequent procedure.
