Title: Heat pump comprising piston type compressor and compressed air motor - uses air as working medium so that air compressed and cooled is expanded in piston type motor and compressor and motor are designed as separate sets
Inventor: RADEBOLD HELMUT
IPC: F25B9/00
Filed: 1992-03-29
Abstract: The separate sets are either mechanically or electrically coupled with each other with an electrical coupling. An electric motor can be provided for driving the compressor and the compressed air motor can drive an electrical generator. The control of the expansion in the motor takes place across rotating valves, which can be driven by a crankshaft across a timing belt, or by a separate motor. The valves provided for the inlet and outlet are adjustable independently of each other. The control of the compression in the compressor results in the same manner. ADVANTAGE - Gives optimum efficiency. Economic series fabrication. Facilitates reliable interference free drive and matching of different output ranges.

IPC: C08L23/08
Filed: 1992-04-04
Abstract: A foil or moulded body made of a thermoplastic material based on at least one partially crystalline polyalkene elastomer and/or elastomer mixture is composed of a multiphase alkene block copolymer with a determined proportion of a heterophase elastomer copolymer of a homopolymer and/or copolymer of an alkene, as well as a polymer modifier. The plastic material contains if required stabilisers, fillers, parting agents, colorants and other usual additives. This foil or moulded body is characterised in that the thermoplastic material contains a multiphase polypropylene block copolymer with about 51 to 85 % by weight ethylene propylene copolymer, with respect to 100 parts by weight polypropylene block copolymer. The thermoplastic material represents a thermoplastic elastomer and from about 70 to 30 parts by weight polypropylene block copolymer, about 30 to 70 parts by weight are constituted by a polymer modifier represented by a homopolymer and/or copolymer of ethylene.

Patent DE-4224753-A1 (DE)
Inventor: EBERT SIEGFRIED DIPL ING
IPC: F16H7/08
Filed: 1992-07-27
Abstract: The problem with prior art automatic tensioning and damping components is that back-distortion energy is wasted between the moving chain strands. The origin of this problem lies in its chain-speed-synchronous rolling movement. The novel tensioning and damping component is designed to waste less energy. The problem is solved by an elastically deformable automatic tensioning and damping component (3), pretensioned between the load strand (1) and the loose strand (2), and fully or partially matched in form on its outer surface with the chain. The novel automatic tensioning and damping component is slidingly retained in the bend in the loose strand and its distance from the chain wheels is thus self-adjusting. The invention is applicable to mechanical engineering.

Title: Electron beam accelerator for agricultural foodstuffs irradiation - comprises electron beams pulsed in hollow resonance zone in opposing phases on differing trajectories
Inventor: ETIEVANT CLAUDE
IPC: H05H7/06
Filed: 1992-11-17
Abstract: The assembly has hollow resonance zone(s) (48) with a unit (58) to form a second electron beam (60). The second beam is in pulses timed to coincide when the hollow zone (48) functions to brake the electrons of the second beam (60). The generator (54) for the first beam (56) delivers it in pulses, in an opposing phase to the second beam (60), and on a different trajectory into the hollow zone. The pref. pulse duration of the two electron beams (56,60), on generations, is max. ca. equal to one-tenth of the electromagnetic field period. The energy of the second beam (60) on transmission is higher than an energy threshold retained by the electrons caught in the hollow zone (48). Electrostatic accelerator tubes (76,70) form the two electron beams (56,60) with HT generator(s) (86) to give the first beam (56) an initial acceleration and to accelerate the second beam (60). The HT generator (86) is a Greinach (RTM) type electronic voltage multiplier. The hollow resonance zone (48) has an outer cylindrical conductor (50) and an inner cylindrical conductor (52) which is coaxial and has openings for a flow through it. The two electron beams are passed into and out of the zone. The accelerator also has electron deflector(s) (62) to deflect an electron beam which passes along the zone's dia. along another dia.. USE/ADVANTAGE - Used to irradiate agricultural foodstuffs directly by the electrons or by X-rays generated by conversion from a heavy metal beating plate. The assembly is simple, cost effective and reliable.
Patent DE-4240972-A1 (DE)
Inventor: ASMUS TORSTEN
IPC: H02P3/08
Filed: 1992-12-05
Abstract: A braking device for a series-wound commutator motor is proposed, which motor has an armature (10) and at least one field winding (11, 12) connected in series therewith, which are both acted on by a supply voltage (Uv) in the motor mode. In this case, a capacitor (20) can be charged, which is connected to the field winding (11) and can be discharged via the field winding (11) in the braking mode. In addition, a changeover device (15, 16) for the braking mode is provided, in which the poled field winding (11) forms a closed circuit with the armature (10), at least one pole of which closed circuit is isolated from the supply voltage. A controllable resistor (17) is used for limiting the current through the field winding (11) in the braking mode. To this end, this controllable resistor (17) is connected in parallel with the armature (10) and is switched off in the motor mode, while being switched on in the braking mode. In consequence, the braking current flowing via the carbon brushes is split into an excitation current through the field winding (11) and a short-circuit current through the controllable resistor (17), as a result of which the excitation field and the current flowing via the carbon brushes of the armature (10) are limited, and escalation of the excitation field and braking current is prevented. <IMAGE>

IPC: B21D5/02
Filed: 1993-05-19
Abstract: In an apparatus for bending sheet metal (13) by pressing the sheet metal (13) into an elongate die (8), rod-shaped rolls (9) are mounted as counter supports for the sheet metal (13) in recesses (10) of the die (8), with the surfaces of which the rolls (9) have a smaller coefficient of friction than with the sheet metal (13).

Date Feb. 16, 1995A felt-tip pen (1) for writing on posters or the like is inserted into an ink pot for refilling and keeping. In order to prevent the outer sides of the felt-tip pen from becoming soiled with ink, the felt-tip pen has an axial groove (12) parallel to the felt-tip (10) entered by a collar (22) that surrounds the opening (21) of the ink pot (20) when the felt-tip pen is inserted through the opening. This groove is designed in an intermediate piece (5) that bears the felt-tip and that is in turn inserted onto the cup-shaped end (3) of the handle with a second groove (11 ) of the same size as the first but oriented in the opposite direction. The felt-tip may thus be inserted on both sides onto the handle (2) and into the ink pot and at the same time it is well sealed in the ink pot.
