Title: Hot fuel gas generator - has closed pressure vessel containing heat exchanger to simultaneously vaporise liq. fuel and water at high temp.
Inventor: HARPMAN WEBSTER B
IPC: F02M25/022
Filed: 1980-02-06
Abstract: The generator comprises a closed pressure vessel (10) having a heat exchanger (16) including an electric heating element (25) and fins (18) extending to the walls of the pressure vessel. Staggered openings in the fins form a passageway (51) for continuously injecting a predetermined amount of a liq. hydrocarbon into the pressure vessel. A valve (20) is positioned in an opening in the pressure vessel, and is in communication with the intake manifold of the I.C. engine. A linkage (45) moves the valve from a closed position to an open position in conjunction with the engine combustion air throttle. A predetermined amount of water is injected (50) into the pressure vessel, the steam/vaporised fuel mixt. passing via filter (22) to chamber (11a).

Title: Automatic temporary connection of cables and wires - uses stackable plastic housing contg. EM latches, and has buffer to actuate auxiliary contact
Inventor: RAPP KLAUS
IPC: G01R1/067
Filed: 1980-02-07
Abstract: The contact arrangement is for automatic temporary connection of cables and wires to a test device for electrical and electronic equipment. It can be operated rapidly using one hand and enables any number of contact positions to be served by choosing the number of elements used. The connection to a cable or wire takes place automatically. The wire is pushed past a contact housing (3) with a contact pin (4) until it presses against a plastic buffer (5). The buffer actuates an auxiliary contact via a spring (6). The auxiliary contact triggers a self-latching electrical circuit which connects the supply voltage to an electromagnet (10). The electromagnet pulls a soft iron lever (11) which presses the contact pin against the wire until the latching current is interrupted. The unit is in a stackable plastic housing (1).

Title: Lithographic printing plate mfr. - by forming protective hardened organo-polysiloxane layer on silicone layer, rendering unprotected areas oleophilic and removing protection
Inventor: TAKEUCHI SATOSHI
IPC: B41M1/08
Filed: 1980-04-22
Abstract: Process comprises (i) providing patterned protective layer, which is made of hardened layer of photohardening organopolysiloxane, on silicone layer coated on support; (ii) rendering specific areas of the silicone layer, where the protective layer is absent, oleophilic using active chemical species existing in plasma state; and (iii) peeling the protective layer off the silicone layer surface. Photohardening organopolysiloxane has surface tension of pref. 20-23 dyn/cm. Organopolysiloxane itself may have sensitive to light, or mixt. of silicone resin and light sensitive substance may be used for making protective layer. Thickness of protective layer is 1-5 mu m.

Patent DE-3033346-A1 (DE)
Title: Safety device for electrical lawn-mower - has on=off switch operated with two hands via pivoted bracket and push-button
Inventor: KOLB WALTER
IPC: A01D69/02
Filed: 1980-09-04
Abstract: A mechanical on/off switch (6) is located in the handle of the mower. The switch must be operated with two hands before it close and apply power to the cutter-motor. Accordingly the switch has two operating members: the first is a push-button (3) and the second a pivoted bracket (2). The latter is located below the handgrip (1) of the mower. When the bracket is pulled up towards the handgrip, an arm (12) moVes into a standby position in which the push-button can be operated to pivot the arm and operate a switching lever (9). When the bracket is released it returns to its original position. A snap-action spring (18) and a switch-off pin (11) cause the lever to return to its original position. If the snap-action spring fails to open the switch, the pin is operated by a safety cam (16) belonging to the arm in order to return a switching member (7) to its original, off position. The advantage lies in combining safety with comfort.

Title: Electric subunit
IPC: H01L23/367
Filed: 1981-07-18
Abstract: In this electric subunit, which is designed in particular as an overvoltage protector for a vehicle electrical system (network), an electronic subassembly such as a diode or Zener diode is provided. This Zener diode is assigned a heat-dissipating cooling plate.

Title: Large container
Inventor: RIEGER HERBERT
IPC: C12G1/024
Filed: 1981-08-21
Abstract: The invention relates to a large container, which can be used for treating crushed grapes, among other things, and on the floor of which there is arranged a motor-driven worm shaft for discharging the rape. The invention consists in the fact that the inside end of a juice outlet pipe (12) is arranged above a horizontal plane (19) which passes through the axis of the worm shaft (14). This ensures that when the juice has been let off, the worm shaft is still in the region of the residual juice and that therefore the rape in this region is still sufficiently loose for it to be discharged by the worm shaft without further treatment. <IMAGE>

Title: Method of producing a negative electrode current collector for alkaline primary cells
Inventor: GUGENBERGER THOROLF DIPL CHEM
IPC: H01M4/66
Filed: 1981-11-20
Abstract: As a precaution against hydrogen gassing in alkaline primary cells having negative zinc-electrodes, provision is made that the negative current collector, preferably in the form of a copper, brass or steel nail, is electrolessly zinc-plated before being pressed into the anode material. For this purpose, it is exposed for several days to the action of hot potassium hydroxide solution containing as a sediment a zinc powder bed in which the current collector is either immersed over a part of its length or to which it is connected in an electrically conducting manner. The section of the current collector, including the head end, coming within the sealing zone remains excluded from the zinc plating or the zinc is removed from it in a separate process step, while at least the zinc-plated part receives a protective paraffin coating.

Title: Mount for the vibration-insulating support of a vibrational unit on a substructure
Inventor: PECHHOLD WOLFGANG PROF
IPC: F16F3/093
Filed: 1981-12-24
Abstract: A mount is specified which is suitable in particular in automotive engineering for a vibration-insulating support of the engine on the chassis or the bodywork of a motor vehicle. The mount comprises, in mechanical series and/or parallel connection, an insulating element, which displays a rubber-elastic dynamic behaviour, and a damping element, which has a high damping in the frequency range of the mass system of the mount. In the case of a parallel connection of insulating element and damping element, the latter preferably consists of a material which is plastic in the static state and at low vibration frequencies and the glass transition process of which does not perceptibly occur until frequencies which are higher than 20 kHz. In the case of the mechanical series connection of insulating element and damping element, for the latter a material is used, for example polyisobutylene, of which the glass transition process is already in effect in the frequency range of the natural vibration of the mass system of the mount and imparts the desired damping.

Title: Pipeline compensator having six degrees of freedom
Inventor: KERZ KLAUS DIPL ING
IPC: F16L27/02
Filed: 1982-02-24
Abstract: A compensator for installation in pipelines which are stressed by thermal expansion. Such a pipeline consists of two parts (1, 2), the fluid circulating in them being able to escape via an annular gap (3) and being able to fill partially a hemispherical housing (35) until it is conveyed back into the main line via a return line (13). An inner intermediate piece (29) and an outer intermediate piece (34) are arranged between the upper part (2) of the vertically arranged pipeline and the housing (35). The inner intermediate piece (29) can rotate about the pipeline part (2) and can also move longitudinally with respect thereto. The two intermediate pieces can be twisted around the pipeline axis with respect to one another, and the outer intermediate piece is suspended on the housing (35). Thus three translational movements and three mutually perpendicular rotational movements of the pipeline parts with respect to one another are possible, the defined restrictor gaps (4, 5, 7) provided between the parts remaining unchanged in their magnitude. The space above the liquid level is filled with gas and is separated from the external atmosphere by pairs of seals (17 to 22). The annular spaces (23 to 25) remaining between the individual seals can be subjected to a barrier gas. <IMAGE>
