Patent DE-4234961-A1 (DE)
Inventor: SCHMETZ KLAUS
IPC: B29C45/73
Filed: 1992-10-16
Abstract: In a temperature-controllable tool (11) or mould for producing plastic mouldings with at least one cavity (12) to accept the mould of the plastic moulding to be produced, at least one inlet or outlet aperture (13, 14) which are interconnected via channels (15) and form a temperature-control agent channel system for cooling or heating the mould cavity (12), the shot time (cycle time) is shortened, maintenance is made easier and higher quality injection-moulded components are obtained in that the run of the channels (15) is matched to the outer shape of the mould cavity (12) and the geometry of the channels (15) is matched to the temperature profile in the plastic moulding. A process for making such a tool or mould comprises the following steps: separating the tool or the mould in the planes of the channels to be produced; producing the channels in accordance with the desired cycle in at least one separating surface of the opened tool or mould by milling or the like; and joining the separated parts of the tool or mould together.
Patent DE-4238455-A1 (DE)
IPC: A47H13/00
Filed: 1992-11-13
Abstract: The invention relates to a device for mounting or taking down a curtain from a rail, the curtain having suspending elements with T-shaped sliding heads and the rail possessing, on its underside, a guide slot running in the longitudinal direction of the rail and intended for guiding through the suspending elements. The sliding heads are pivotable through 90@ against spring action and can then come out of the guide slot of the rail. A hang-up magazine with an entry channel for the suspending elements can be attached in the region of the guide slot. The hang-up magazine additionally has a control curve with a narrowing, such that the sliding heads of the entering suspending elements are turned through 90@ via a cam and can thus be transferred from the rail to the hang-up magazine, in which process the suspending elements are securely guided by guiding flanges in a guiding curve of the hang-up magazine. The hang-up magazine furthermore possesses a flexible magazine bar which eventually receives all suspending elements, so that the curtain in question can be taken out of the rail or conversely introduced into it again. The hang-up magazine can be folded up by virtue of the flexible magazine bar to form a package which is suitable for passing through openings of washing machines, with the result that the curtain can be washed together with the hang-up magazine. <IMAGE>

IPC: F16J15/12
Filed: 1992-12-03
Abstract: The surface shape of the seal has peaks (1) and troughs (2) coated with an elastic layer so that at least the high peaks are covered. When pressing against the surface to be sealed the covering elastic layer is forced both sides into the adjoining troughs and only a thin residual layer remains on the force-transferring tip.

The troughs and peaks can be parallel to each other side by side and in any shape. USE/ADVANTAGE - For cylinder head seals in IC engines. Reliable seal is provided which follows movements in sealing gap.

Patent DE-4312150-A1 (DE)
Title: Method for setting the delivery capacity (pumping capacity, pump horsepower) of a liquid recirculation pump (recirculating pump, return pump)
Inventor: HENNEL EWALD
IPC: F04D15/00
Filed: 1993-04-14
Abstract: A method is specified for setting the delivery capacity of a liquid recirculation pump which can be driven by a variable-speed electric motor and is arranged in the piping system (conduit system) of a heat treatment installation. The speed of the electric motor is controlled by a controller which is fed as input variable an electric voltage which is proportional to the flow velocity of a medium moving in the piping system of the heat treatment installation. As output variable for controlling the speed of the electric motor, the controller delivers electric voltage values which are higher for each flow velocity of the medium in the piping system than the voltage values which correspond to the impressed and calculated piping network characteristic of the heat treatment installation. The outside (external, ambient) temperature prevailing at the building in which the heat treatment installation is located is fed together with the feed temperature of the medium in the piping system as further controlled variable to the controller. In order to minimise the energy requirement, the feed temperature is continuously set by the controller to values for which the liquid recirculation pump is operated at optimum efficiency.
Patent DE-4316849-A1 (DE)
Title: Operation of torque converter by-pass coupling in car automatic gearbox - using control valves enabling rigid connection between impeller and runner in torque converter using working fluid pressure
Inventor: KRUSE GEORG DIPL ING
IPC: F16H61/14
Filed: 1993-05-19
Abstract: The procedure for the smooth activation of a torque converter by-pass coupling utilises a rigid connection between the impeller coupled to the engine crankshaft and the runner driving the gearbox. The connection is activated or de- activated by hydraulic pressure through control pistons and valves. The fluid pressure for all gearbox members (brakes and couplings) is the same as that for the by-pass coupling. The valves for the latter remain in their switched state until the control pressure has sunk from a load dependent normal pressure to a minimum threshold, at which point they change state and switch the coupling in or out. The coupling is a digitally switched electrical valve. ADVANTAGE - No need for expensive pressure modulator for  coupling.

Patent DE-4326340-A1 (DE)
Title: Pneumatic control valve
Inventor: PUSCH DIETER
IPC: F01N3/32
Filed: 1993-08-05
Abstract: In such a control valve the tightness is dependent upon the diaphragm size of the adjusting element. In order to achieve absolute tightness in the event of increased counter pressure without increasing the size of the diaphragm, it is proposed that in the closing and opening phases the adjusting element be reversibly subjectable to the intake pressure of the internal combustion engine and the atmospheric pressure respectively. The new control valve is thereby suitable for use in an internal combustion engine.

Title: Road vehicle front section - contains operating devices and accommodation for battery inclined at specific angle
Inventor: SCHULENBURG JENS DIPL ING
IPC: B62D21/15
Filed: 1993-09-20
Abstract: The front section contains deformation components for conversion of kinetic energy into deformation work in the event of a crash. The battery retainer (8) at least in the event of a crash is inclined by an angle (beta) forwards against the horizontal, which ensures by inertia the movement of the battery (7) out of its accommodation (8). Where the retainer (8) accommodates at least two batteries (6,7) arranged in the vehicle longitudinal direction, the retainer (8) is inclined forwards by an angle (beta) to the horizontal, which ensures by inertia the movement outwards of at least a rear battery (7). The retainer is located on pedestals supported on the vehicle side at the front and rear (12,13) in such a way that it adopts the inclination angle (beta) only in the event of a crash. USE/ADVANTAGE - To move a battery out of its location in the front section of a vehicle in the event of a crash.

Patent DE-4345035-A1 (DE)
Title: Picture-generating device
Inventor: KARASAWA KAZUNORI
IPC: G03G21/14
Filed: 1993-12-30
Abstract: In a picture-generating device a control unit controls the application of a bias voltage in order to ensure that unnecessary sticking of toner to a photosensitive element due to the formation of fog during the start of the operation of a photosensitive drum and during a termination of the operation of the photosensitive drum is prevented in the following manner: The photosensitive drum is started under the precondition that a positive developer bias voltage is applied during the start of an operation by an energy source to a first and a second developer roller and that a charger is switched on. The developer bias voltage, which is applied, is then changed from the positive to the regular developer bias voltage. Furthermore, a developer aid is switched on before a point in time at which a front edge part of a latent picture area reaches on the photosensitive element a position opposite the first roller. On the other hand, during the end of the operation of the drum and after the end edge part of the latent picture area has passed that position which is opposite a first roller, the developer aid is switched off as soon as possible. After a predetermined time has elapsed, the regular developer bias voltage is changed to a positive one, and the charger is switched off.
