Patent DE-3834852-A1 (DE)
Inventor: ZVONKOVIC JOSIP
IPC: F02F3/00
Filed: 1988-10-13
Abstract: A cooled two-piece trunk piston for internal combustion engines has a cast or pressed upper part that contains the piston ring groove and the piston pin hub, as well as a rod hingedly connected to the upper part exclusively by means of a piston pin. The upper part (1) is provided with a radial cooling oil channel (3) closed on all sides by the base material of the upper part of the piston, inside the ring groove section, into which the cooling oil is introduced in any appropriate manner and from which it is evacuated through at least one cooling oil outlet (5, 6) arranged in the direction of the piston pin between the piston pin hubs of the upper part of the piston. The cooling oil outlet(s) (5, 6) open into the free inner space of the rod (2). An oil collector (7, 8) arranged underneath the cooling oil outlet(s) (5, 6) is formed in the upper area of the rod (2) and directs the oil coming out the outlet towards the centre of the bottom of the upper part (1) of the piston.

Title: Rotation control system for the charge cycle in engines working on the 4-stroke principle
Inventor: MICHL UWE
IPC: F02B75/02
Filed: 1988-11-17
Abstract: In 4-stroke engines the exhaust and refill have hitherto been performed by valves, problems such as flow losses, design and production cost, limited engine speed, susceptibility to wear and service costs having led to multiple variations in the position, number, actuation, material and cooling of the valves. The new control system is intended to minimise these disadvantages. A hollow shaft (1) with segmental cut-outs (2) controls the admission of fresh gases and discharge of exhaust gases according to the stroke by way of segmental cut-outs in the cylinder head (3) and at the same time serves as fresh and exhaust gas channel. In the said method the flow losses are lower, the design and manufacturing cost is reduced, the engine speed consistency is greater, the wear performance and the ease of servicing are better than in the valve timing system. The rotation control system, moreover, easily permits the use of ceramic materials in engine construction, which due to the reducible working temperature can lead to increased thermal efficiency and to the omission of conventional cooling. The rotation control system is suitable for all 4-stroke engines such as spark ignition and diesel engines. <IMAGE>

Patent DE-3840729-A1 (DE)
Inventor: MERKLE HANSJUERGEN
IPC: B42D25/43
Filed: 1988-12-02
Abstract: For multicolour marking of identity cards and the like, the multilayer identity card is provided with an outer coloured layer in a first colour and an inner coloured layer in a second colour. While the outer coloured layer absorbs virtually none of the laser light used for marking, the second, inner coloured layer absorbs the laser light. This causes the material in the second coloured layer to be thermally degraded, i.e. evaporated, sublimed or subjected to a chemical or physical reaction, during the marking operation, with the consequence that formation of pressure causes the first layer to be broken up into particles, causing the second coloured layer to become visible. The second coloured layer may also be replaced by a transparent coat of varnish having appropriate properties in order to expose, for example, a multicolour security printed image under this transparent coat of varnish.

Title: Valve arrangement for the control of a plurality of simultaneously operable hydraulic consumers independently of load
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F15B11/16
Filed: 1988-12-30
Abstract: In a valve arrangement for the control of a plurality of simultaneously operable hydraulic consumers independently of load, to which in each case a directional control valve for controlling the pressure-medium quantity and a pressure balance are allocated, the pressure balance is arranged between the consumer and a tank-side control edge of the directional control valve. Acting on the control piston of the pressure balance is the pressure difference between the pressure at the tank-side control edge in accordance with the pressure difference to the tank and in the opposite direction a pressure signal of a low-level external pressure source. According to the invention, not only pushed loads but also pushing loads can be levelled independently of load. Furthermore, the pump controller of a variable-displacement pump can also be influenced as a function of the consumers in order to influence the delivery flow of the pump in accordance with the requirements of the consumers.

Title: Centrifugal force switch for motor vehicles
Inventor: BROZIO GERARD
IPC: B60Q1/44
Filed: 1989-03-16
Abstract: Centrifugal force switch for motor vehicles for preventing rear-end collisions by virtue of the brake lights or flashing hazard warning lights being switched on promptly. The centrifugal force switch is switched on by the centrifugal forces occurring during a sudden braking process (rear-end collision). It then switches on the flashing hazard warning light system or the brake lights at intervals so that the driver behind is promptly warned of the hazard up ahead and can thus react promptly himself. The centrifugal force switch can be installed at relatively low cost in new vehicles and vehicles which are already in use and can prevent a large number of accidents.

Title: Adjusting continuous steel band press - longitudinal axis of one band can be turned about central vertical axis while applied pressure is briefly released during prodn.
Inventor: BIELFELDT FRIEDRICH BERND
IPC: B30B15/04
Filed: 1990-06-01
Abstract: In a continuous press, for the production of chipboard, hardboard, plywood etc., where the pressure is applied by flexible endless steel bands which carry the load through the press, the bands are guided along the longitudinal axis of the press. They pass over drive rollers and guide rollers round over the press top/bottom platen; with an adjustable press daylight, they are supported by rollers and bearings on both platens. The steel bands on the top/bottom platens are adjusted about the longitudinal axis of the press by turning the top platen horizontally, together with its drive and guide rollers; they are turned about a vertical axis at the centre of the press; shortly before this the short-stroke pressure cylinders in the high pressure area are released and remain so until the platen has been turned. ADVANTAGES - The method enables the top platen to be adjusted precisely in alignment with the bottom - platen in reference to their longitudinal axes., and to do this during production without straining the steel band.

Title: Optical monitor for cylindrical bodies - has upper mirror wedge and lower ring mirror to give reflected light for sensor
Inventor: BIRKLE GEBHARD
IPC: G01N21/952
Filed: 1990-07-05
Abstract: The assembly to give a continuous monitoring action for components which have a cylindrical cross-section, has a ring mirror (9) for the body to pass through, and an upper mirror structure (1) which has two mirrored surfacs as wedged surfaces (2,2') at an angle (delta) to each other. They have a longitudinal form with a symmetrical optical alignment to the mirror surface (11) of the ring mirror unit (9). The common edge (3) of the mirror wedge is centrally above the passage opening (10) of the ring mirror (9). The passage opening (4) through the mirror wedge passes symmetrically through one of the half sections (61,61') so that the focussed beam is divided into two part-beams (16,16') each to strike an angled surface. Further flat or refractive surfaces (5',6',7',8') face each other to deflect the part-beams to the half (61') of the mirror wedge opposite that with the opening passage. The part-beams are reunited into a single beam directed at the sensor (13). ADVANTAGE - The assembly can monitor the running of a relatively long test piece, over a number of zones along its length, to detect faults or irregularities.
