Patent DE-3146653-A1 (DE)
Title: Spark plug for internal combustion engines
Inventor: ESPER FRIEDRICH DR
IPC: F02B3/06
Filed: 1981-11-25
Abstract: The invention relates to a spark plug for internal combustion engines, in particular for internal combustion engines without externally supplied ignition. The spark plug comprises a thin-walled ceramic tube in the longitudinal bore of its metal housing, which tube is closed off on the combustion space side with a floor; a layer-shaped heating element which is electrically connected, via conductor tracks, to the terminal-side end section of the ceramic tube is mounted on the outside and/or inside of the ceramic tube floor. The heating element is constructed in a wave shape or as a constriction of the terminal conductor tracks and is preferably covered with a gas-tight protection layer. A porous ceramic intermediate layer can be arranged between the heating element and ceramic tube floor; in the case of very small-surface heating elements, a heat-conducting layer is also required between the intermediate layer and the ceramic tube floor. Spark plugs according to the invention reach the temperatures required for ignition of the fuel vapour/air mixtures in less than two seconds and can be easily equipped with an optoelectric combustion space sensor. <IMAGE>

Title: Process and device for the testing and sorting out of knurled coins
Inventor: LUDWIG MAX
IPC: G07D3/14
Filed: 1981-11-27
Abstract: The invention relates to a process for testing and sorting out coins knurled in the edge region in a coin-testing device. The object of the invention is the detection and sorting out of the knurled coins. The object is achieved in that sufficient kinetic energy is taken from a rolling knurled coin (1), guided in a coin channel, by a catching lever (5) projecting into the coin channel and acting on the edge region of the coin to ensure that the coin does not overcome a hurdle (7) arranged at the end of the coin channel and falls into the sorting-out channel. <IMAGE>

Patent DE-3151389-A1 (DE)
Title: Expeller
Inventor: TWELE HORST ING GRAD
IPC: F25B33/00
Filed: 1981-12-24
Abstract: An expeller, in particular for an absorption heat pump, has a boiler pipe arrangement which is acted upon with heat by a burner and into which solution rich in refrigerating medium enters at an inlet connection piece and from which evaporated refrigerating medium emerges at an outlet connection piece situated at the top. In order to achieve, with low constructional outlay, an extensive expulsion of the refrigerating medium, the boiler pipe is formed by a pipe coil (10) which has an uninterrupted gradient from the inlet connection piece (12) to the outlet connection piece (14) of the solution which is low in refrigerating medium. The flow cross-section (D) of the pipe coil (10) is so large that the refrigerating medium solution flowing through the pipe coil (10) only fills the same to a level (N) which is lower than the flow cross-section (D). <IMAGE>

Title: Cleaning device for electrophotographic copiers
Inventor: HOCHBERG HELMUT
IPC: G03G21/00
Filed: 1982-01-22
Abstract: In a cleaning device for electrophotographic copiers, a flexible cleaning blade (2), the rear edge (2b) of which is enclosed by the U-shaped groove (3a) of a leaf holder (3), bears with its cleaning edge (2a) against the surface of an electrophotographic recording medium (1). In order to join the cleaning blade (2) permanently to the blade holder (3) in a simple way, without impairing the flexibility of the blade, its rear edge (2b) is joined to the base (3b) of the U-shaped groove (3a) of the blade holder (3) by means of an adhesive tape (4) coated on both sides with a contact adhesive. The use of the adhesive tape also dispenses with the crosslinking time required for a liquid adhesive if such an adhesive is used. <IMAGE>
Patent DE-3203020-A1 (DE)
Title: Automatic headlight adjustment on motor vehicles when the level of the chassis is changed after loading of the boot or after travelling over bumpy ground
Inventor: WAGNER DIETER KARL
IPC: B60Q1/11
Filed: 1982-01-29
Abstract: The present idea ensures that the headlights adjust themselves automatically to the position with respect to the carriageway which has been set in the state of rest of the vehicle, when position changes of the chassis due to oscillations or loading of the boot change the setting of the headlights with respect to the carriageway. In each case a cam attached to the oscillation element controls a hydraulic cylinder connected to the chassis. The control is dependent on the oscillation of the chassis which changes the position of the headlights and the position of the oscillation elements. The displacement distance of the oscillation of each oscillation element is reduced via the cam and transmitted to the cylinder. With the pressure piston, a second cylinder, which is connected to the corresponding headlight, is actuated via a rigid tube system and initiates the correction of the swivellably mounted headlight. By means of corresponding positioning (diagonal arrangement, front with respect to the rear) and changing the mode of operation (opposed operation of individual cylinders), each type of oscillation of the vehicle is included in the control system.

Title: Vibrator device
Inventor: STEINBACH LEONHARD
IPC: B06B1/16
Filed: 1982-03-05
Abstract: A vibrator device has a rotatably mounted and driven vibrator shaft (1) with coaxial cylinder space (2). At least one mass element (5) penetrates the cylinder space and is guided in shaft slots (3, 4) parallel to the axis. The mass element contains approximately in the centre a guide opening (6) which is inclined at an angle with respect to the axis (14) and to which a likewise inclined guide pin (7) of a control element (9) engages. The control element is axially adjusted in the cylinder space (2). The adjustment takes place advantageously via a fixed hydraulic cylinder (12) whose piston rod (11) is connected rotatably to the control element (9) without play. Further mass elements are adjustable in a similar manner in the cylinder space (2) via a connection to the other end (22) of the guide pin (7). In one position of the control element (9), the mass element (5) has a position with respect to the vibrator shaft (1) in which the latter is free of unbalance. In another position a maximum degree of unbalance is obtained. <IMAGE>

Patent DE-3228430-A1 (DE)
Title: Continuously adjustable two-way built-in valve
Inventor: KURZ MANFRED DIPL PHYS
IPC: F16K31/40
Filed: 1982-07-30
Abstract: The invention relates to a continuously adjustable two-way built-in valve, the control member of which is loaded by a restoring spring located in a spring space and is pilot-controlled by a hydraulic follow-up system. The invention is to make possible a change in the direction of flow in the valve, is to reduce the consumption of control oil and is to improve the dynamic behaviour of valves of this type. The object of the invention is to provide such a valve without the use of a constant restrictor, in which valve the oil can flow in both directions and external discharge of the control oil is possible. This is achieved by virtue of the fact that the control member or a cylinder piece connected to it has a control space connected to the spring space and that the control space, by a follow-up piston, guided by the control member or the cylinder piece, inside the control member or the cylinder piece or on the circumference of the cylinder piece, can be connected to an inflow line or an outflow line via two control edges on the follow-up piston.

Title: Wheel suspension for motor vehicles
Inventor: STOTZ ERICH
IPC: B60G7/02
Filed: 1982-11-20
Abstract: The wheel suspension, especially of semi-trailing arm construction, comprises an inner and an outer control arm. Both control arms are held on the vehicle body by way of joints, the inner control arm being additionally pivoted by way of a control oscillating link. The joints are arranged in such a way that one wheel steering origin is formed outside the track width and behind the vertical wheel centre transverse plane in relation to the direction of travel. The body-side joints of the control arms and the control oscillating links are designed in such a way that in the event of forces acting on the wheel when braking and when cornering the wheel suspension element and hence the wheel is adjusted. This wheel adjustment occurs in the toe-in direction and, for compensation of wheel position variations, in the toe-out direction.
