Title: Rotary piston engine
IPC: F02B57/08
Filed: 1988-03-30
Abstract: The invention relates to internal combustion engines; subsumable concept: rotary piston engines. In the rotary piston engine described the cylinders are arranged radially and are accommodated in a rotor. In order to achieve uniform concentric running, 3 pistons or an odd number of pistons are employed. The elongated piston pins engage in guide stars fitted on each side, which are fixed to the housing. The rotor is set in rotation by the downwards movement of the piston. The guide star has 4 tdc and 4 bdc. 2 spark plugs, 2 inlet ports and 2 exhaust ports are located in the housing, see drawing, Fig. 1. The spark plugs are offset by 180@ in relation to one another. The tdc are offset by 90@ in relation to one another. Two working strokes are obtained for one revolution of the working shaft. The engine can be used for all internal combustion engines. <IMAGE>

Patent DE-3816875-A1 (DE)
Title: Self-moving fishing float
Inventor: HORN WALTER
IPC: A01K93/00
Filed: 1988-05-18
Abstract: Fishing floats conventional hitherto only permit inactive fishing bait to be offered at a predetermined depth. As a result of the present invention, the float automatically rises and falls under water at intervals. The float consists of a spindle-shaped hollow body (1, 2, 3) with flooding apertures in the bottom of the float and in the centre (4) and at the tip (5). The tip aperture is provided with an outlet valve (6, 7) which is controlled by a buoyancy body above the float (9). Accommodated in the lower part of the float is a perforated chemical container with a gas-generating propellant (11). When immersed in the water, the float fills and sinks (Fig. 2). When the float dips, the outlet valve closes. The chemical container produces gas as a result of the ingress of water. The gas forces water out of the housing and generates buoyancy. The float rises. On the surface of the water, the valve buoyancy body opens the valve, buoyancy gas escapes, the float is flooded and sinks. The process is repeated until the chemicals have been consumed (Fig. 3). The object of the invention is to make it possible for inactive fishing bait to rise and fall in order to give the target fish the illusion of live prey. <IMAGE>
Patent DE-3820135-A1 (DE)
Inventor: BRETTSCHNEIDER WOLFGANG DIPL I
IPC: B60C15/02
Filed: 1988-06-14
Abstract: The invention relates to a vehicle tyre having a carcase which is embraced by two bead cores, the bead cores consisting of rigidity carriers such as plastic filaments and/or metal wires and it being possible to turn up the beads. In order to improve the objects required of the beads without adversely affecting their facility to turn up, it is proposed that the surface of the rigidity carriers of the bead cores prevents adhesion to vulcanised rubber, at least when the rigidity carriers are moistened in the vulcanisation position of rubber, so that each rigidity carrier is individually rotatable about its longitudinal axis with respect to the surrounding bead rubber. <IMAGE>

Patent DE-3837956-A1 (DE)
Title: Apparatus for lateral sealing of press rolls
Inventor: EICHLER DIETRICH DR
IPC: B01D33/067
Filed: 1988-11-09
Abstract: The invention relates to an apparatus for lateral sealing of radially movable press rolls in equipment for solid-liquid separation of solids from liquids, for example for separating liquid manure (slurry) into a solid and liquid phase. The aim of the invention is simpler structural design of the lateral seal. The object is achieved according to the invention by utilizing the rubber casing vulcanised into the press roll for the generation of the necessary pretension of the seal. The axial elasticity is achieved by detaching the rubber casing from the supporting steel roll over a length of 5 to 8 cm, holding it with an axially movable support ring and improving its sliding behaviour by a lateral ring.

Inventor: KICHERER ROBERT ING GRAD
IPC: H01H37/36
Filed: 1988-12-31
Abstract: In an electric switching device (1), particularly constructed as a temperature regulator, the resilient switching arm (14) controlled by a hydraulic expansion cell (12) for operating a snap switch (5) is fixed by means of positively engaging snap connections (32) to plate-like support parts (20) of a sheet metal support body (3) of a body (2), the support parts (20) on either side of the switching arm (14) being at right angles to joint axis (25) of arm (14) as lateral bends to a base plate (30) of support body (3) and receive between them an end portion of an insulator (4) carrying the switch (5). This leads to an extremely favourable taking up of forces, so that the support body (3) can be made from extremely thin sheet metal as a relatively elastic component. It also leads to a very simple assembly of the switching arm (14).

Title: Method for determining atmospheric conditions by means of laser beams and device for carrying out the method
Inventor: SCHOTTELIUS HORST-ULF
IPC: G01N21/39
Filed: 1989-01-25
Abstract: A method and a device (10) for determining atmospheric conditions such as density fluctuations or contaminants by means of high-energy laser beams (22, 24, 26) are described, the laser beams being emitted by a transmitter (12) and picked up by a receiver (14) and being evaluated in an electronic device (38) of the receiver (14). In so doing, at least two laser beams (22, 24, 26) of different wavelengths are generated in the transmitter (12), are unified in a unification device (28) of the transmitter (12) into a laser main beam (30), which is directed towards the receiver (14). A detector (36) provided in the receiver (14) serves for the conversion of the laser main beam (30) into an electric signal, which is amplified by an amplifier and is compared with a reference signal (56) representing the frequency and/or phase position of the beam modulations of the laser main beam (30). <IMAGE>
Patent DE-3905105-A1 (DE)
Title: Cable feeder for a cable winch carried by a vehicle
Inventor: PFANZELT PAUL
IPC: A01G23/00
Filed: 1989-02-20
Abstract: Previously known, radio-operated cable feeders require careful attention on the part of the forestry worker, when the cable is being drawn out, in order to ensure that unnecessarily large quantities of cable which interfere with the work flow are not fed out. In order to guarantee immediate switching-off of the cable-feeding drive when the drawing-off of the cable (4) does not keep time with the feeding, a cable deflection roller (9) interacts with a force sensor which generates a trigger signal for the drive motor (16) only when a predetermined cable tensioning force is reached and in the opening direction of the drum coupling and brake of radio-controlled cable winch (2). This ensures that when the cable tensioning force slackens, for example when the forestry worker is stationary, the drive motor of the cable feeder is stopped, even when the forestry worker has given no radio command to this effect. <IMAGE>

Patent DE-3926705-A1 (DE)
Inventor: IDELCHIK MICHAEL SOLOMON
IPC: F02D41/26
Filed: 1989-08-12
Abstract: The control system has a first (12) and second (14) channel which simultaneously monitor and control engine operation. The first channel receives a set of inputs (22) and processes (26, 46, 32) the inputs to form a first rate signal (34). The second channel also receives the same set of inputs (22) and processes the inputs (56, 76, 62) to form a second rate signal (64). The first and second rate signal are coupled to a means (36) for combining the signals and the output is coupled to a common integrator (38) which activates an actuator (40) of the engine. The engine is monitored (42, 72) to provide monitor signals (44, 74) which are fed back to processors (46, 76) of the channels (12, 14). The sets of inputs (22) for the channels may be derived from respective duplicated sets of sensors. The system may be used to control a fuel metering valve, the position of which is monitored (at 42, 72). The provision of two control loops (12, 14) ensures against failure. <IMAGE>
