Title: Piston for an internal combustion engine
Inventor: MUELLER JOCHEN DIPL PHYS
IPC: F02B23/06
Filed: 1986-09-13
Abstract: A complete insulation of the combustion chamber by means of materials with a low thermal conductivity led to previously unexpected effects, that is to an undesirable increase of the fuel consumption and the NOx content of the exhaust gases. Since insulation, however, especially of the piston, brings advantages in terms of the heat to be dissipated, because the running characteristics are thereby improved, the piston according to the invention offers an optimum compromise with regard to the insulation.   The piston (1), which contains a combustion chamber recess (7), with the exception of the combustion chamber recess comprises at least one layer of material of low thermal conductivity (9, 11, 18) with a dense surface (Fig. 1). <IMAGE>

Title: Combination doubler
Inventor: DELLERT ROLAND
IPC: F03G7/06
Filed: 1986-10-14
Abstract: In the combination doubler use is made of the forces occurring in expansion and contraction, both longitudinal and also volume expansion/contraction. Due to the conversion of volume expansion into longitudinal expansion, which characterises the combination doubler, a much higher power output can be achieved compared to the doubler based on longitudinal expansion.  Advantages: Smaller construction, therefore cheaper  Adaptation of form, for example in vehicle construction  Higher power output than normal doubler  More rapid control of the stroke Many possible applications.i

Title: Method for impedance transformation
Inventor: ESPRESTER RALF DR ING
IPC: H03H7/40
Filed: 1986-12-24
Abstract: In a method for impedance transformation of a complex antenna impedance to a real impedance over a wide frequency range, test signals of adjustable frequency are generated in an adaption phase and the standing wave ratio is measured in each case. This results in mutually adjoining frequency intervals with uniform adjustment of the transformation elements of the adaption network interval by interval and VSWR values below a predetermined maximum value. Parameter records unambiguously characterising the initial frequencies of the intervals and the associated adjustment of the adaption network are stored. In the actual transmitting/receiving operation after termination of the adaption phase, a parameter record belonging to the instantaneous operating frequency or the next-lower stored frequency is read out of the memory for adjusting the adaption network.

Title: Device for controlling the angle of inclination of a wagon body for pneumatic spring bogies as a function of track bends
Inventor: MOHACSI SANDOR DR ING
IPC: B61F5/22
Filed: 1987-04-08
Abstract: In the device for controlling the angle of inclination of a wagon body as a function of bends in the track, it is intended that it will be possible to vary the height of the rolling pole independently of a structure once it has been set up. According to the invention, this is achieved in that the pneumatic spring bellows 2 of a secondary suspension are supported via vertical cylinders 3 on a longitudinal beam 4 of a bogie frame. These vertical cylinders can be actuated by a second control unit 24, a relief cylinder 27 with relief piston 28 and control piston 30 is connected between the pressure source 23 and the vertical cylinders 3 in order to relieve the hydraulic pressure source 23. Independently of the vertical cylinders 3, horizontal cylinders 15 are provided which can be actuated by a first control unit 20 and displace one rocker 9 (Figure 1) transversely with respect to the direction of travel, this rocker 9 being rigidly connected to lower rims 8 of the pneumatic spring bellows 2. By virtue of the movements, which are matched to one another, of the vertical and horizontal cylinders 3 and 15, the height of the rolling pole can be varied to a large extent. <IMAGE>
Patent DE-3714173-A1 (DE)
Inventor: BEINHOLD GEORG ING GRAD
IPC: H03K17/08
Filed: 1987-04-24
Abstract: To equalise the distribution of voltage at a series circuit of gate-controlled semiconductors (V1, V2) having turn-off times of different length, it is first determined by delivering the turn-off signals at the same time, with a low current flowing through the series circuit, which of the semiconductors (V1, V2) is the last one to turn off. Then the deliveries of the turn-off signals to the semiconductors (V1, V2) which previously turned off earlier are in each case delayed at higher currents until, finally, at full operating current, until these semiconductors turn off at the same time as the semiconductor with the longest turn-off time. This delay can be compensated via load-current-dependent correction elements (K1, K2) at the ratio of the instantaneous turn-off current values of two successive conductive phases of the series circuit. <IMAGE>

Patent DE-3735199-A1 (DE)
Title: Electrical switching arrangement, especially a mains voltage stabiliser
Inventor: SPITZENBERGER CARL
IPC: H02M5/458
Filed: 1987-10-17
Abstract: In the case of a circuit arrangement (for example a mains voltage stabiliser) for producing a stabilised output AC voltage from an input AC voltage, two AC voltage signals are produced in the input circuit of the circuit arrangement, which signals are each composed of a DC voltage component and an AC voltage component whose frequency is identical to the input AC voltage. One half-cycle of the AC voltage components is in each case used in normal operation to induce the output voltage by suitably driving a [lacuna] the current through a primary circuit of an output transformer whose secondary supplies the output AC voltage. The DC voltage component of the AC voltage signals provides a contribution to the output AC voltage when the input AC voltage falls below a predetermined nominal value or the output of the circuit arrangement is loaded more heavily than in normal operation. The DC voltage component of the AC voltage signals thus forms a voltage reserve, which can be used to compensate for any drops in the output AC voltage.

Title: Method for making fixing holes or valve holes in a disc or a rim of a wheel of a motor vehicle
Inventor: WINKLER HANS-HENNING DR ING
IPC: B23B41/00
Filed: 1987-10-23
Abstract: A method is used to make holes in wheels of motor vehicles, in particular to make fixing holes (14) in a disc (12) or valve holes in a rim of the wheels. The hole is provided, in the region of surfaces (35, 36) of the disc (12), with a larger diameter (D1, D3) than between the surfaces. To be able to countersink the wheels in a single clamping in the region of the hole also on the side facing away from the working side, use is made of a tool (60) which, at its underside, is constructed hook-like (62, 63, 64, 65) and can be pushed, with a radial offset, in the vertical direction (70) through the hole. The tool (60) is then brought back into a position in alignment with the axis (15) of the hole, drawn in and turned, so that a countersinking (44) of larger diameter is produced. By reversing the order of the steps, the tool (60) can be removed from the hole again (Fig. 4). <IMAGE>

Title: Fluid cooling system for an internal combustion engine with preheating of the oil
Inventor: HALLBAUER HANS-JOACHIM
IPC: F01P9/00
Filed: 1987-11-04
Abstract: In internal combustion engines with three-circuit cooling system and honeycomb cooling (2), the cold blockage within the tube of the oil cooler (3) prevents the flow of oil when the oil circuit is switched over from the short-circuit line (33) to the oil cooler (30). Preheating of the oil cooler by a heating component (9) attached thereto liquefies the cold oil within the oil cooler even during the start-up phase so that when the oil circuit is switched over to the oil cooler the oil can flow through unimpeded. The heating component (9) can optionally be integrated in the low-temperature circuit (21) and/or in the high-temperature circuit (11), either a partial amount of water or the entire amount of water of the respective circuit flowing through the latter by means of a flow rate control device (8). <IMAGE>

Title: Plastics moulding comprising a plurality of regions made of different polyurethane
Inventor: REUBER GERHARD
IPC: B29C31/10
Filed: 1988-02-13
Abstract: Polyurethane (PUR) allows a large number of properties, such as for example great low-temperature impact strength, great overall strength, fast demoulding time, low yield pressure and the like. However, generally it is only ever possible to achieve a number of these properties by corresponding adjustment and choice of the formulation of the PUR. At the same time, however, there is the desire to cast in a single mould moulded parts which are as large and extensive as possible and are intended to have different local sections of different properties, such as for instance varying colouration or different hardness or elasticity in spatially separate sections. The object of the invention is therefore to improve the suitability of PUR mouldings for different applications. In principle, the invention consists in building up even stretched-flat bodies within the casting mould from a plurality of polyurethanes of different formulations. This measure allows the effect to be achieved that individual sheet-like sections of the plastics moulding stretched in a sheet-like form have the desired technical properties. For this purpose, the layers preferably merge with one another in a wedge-shaped manner, so that a plurality of PUR layers of different properties are laid one over the other. <IMAGE>
