Title: Load-related brake pressure regulator
Inventor: SCHOPPER BERND ING GRAD
IPC: B60T8/18
Filed: 1981-10-22
Abstract: The load-related brake pressure regulator according to Fig.1 has two control pistons (2, 2') displaceably arranged in a housing (1) fixed to the vehicle body with control valves assigned to these in a twin arrangement. A two-armed transmission lever (5) is supported on the ends of the control pistons (2, 2'); a control spring (7) in the form of a helical tension spring (8) supported on and fixed to the housing acts on one end of the lever arm and a transmission linkage (9), which is movable as a function of the load acts on the other end of the lever arm. Owing to the load-related movement of the transmission lever (5) a control force determined by means of the helical tension spring (8) and the lever geometry is applied to the control pistons (2, 2') thereby determining the regulating behaviour. In the event of a failure of the transmission linkage (9) the transmission lever (5) strikes a stop (14) fixed to the housing owing to the force exerted by the helical tension spring (8). The residual pretension of the helical tension spring (8) present in this position defines a minimum switching pressure, which is also assured even in the event of malfunctioning of the transmission linkage (9). <IMAGE>

Title: Method for generating a calibrated clock circuit, and clock circuit calibrated in accordance with the method
IPC: G04F5/06
Filed: 1982-02-13
Abstract: The aim of the method and of a clock circuit (1) calibrated in accordance with this method is an inexpensive method product which can be installed directly into a clock mechanism. For this purpose, integrated calibration capacitors are connected, at the base of the integrated circuit (19) on conductor frames (18), to the integrated oscillator, as determined by the size and distribution of the deviation from natural resonance of a ready-to-install batch of stored crystal resonators (7) which are later inserted into a recess (5) of an injection-moulded body (2) where they are connected to the conductor frames (18), in such a manner that the circuit oscillators have approximately the same deviations from the operating frequency required later as the frequency of the ready-to-install frequency-classified crystal resonators (7), but with the opposite sign from these. Finally, each circuit (19) is equipped with the crystal resonator (7) of opposite frequency deviation. This provides a series of circuits (1) which are permanently calibrated to the operating frequency without further calibration requirements and without having to maintain a costly store with types of defined natural resonance for the crystal resonators (7). The circuit (1) thus calibrated can be inserted directly, that is to say without requiring a separate circuit board to be installed due to the lack of external calibration components, into a clock mechanism and mounted on a suitable clock mechanism component. <IMAGE>

Patent DE-3301483-A1 (DE)
Title: Enlarging device having continuous focusing in conjunction with variation of the image size by means of a lens controlled via a bridge circuit and an amplifier
Inventor: BOEHME RUDOLF
IPC: G03B27/34
Filed: 1983-01-18
Abstract: Enlarging device, in particular for photographic purposes, having electrical control of the lens for the purpose of continuous, automatic focusing. By converting the optical dimensions of image distance, subject distance and lens focal length into equivalent electrical values such as, for example, resistances with the aid of sensors of fixed and/or adjustable resistors, which are parts of a bridge circuit, a control signal is transmitted via an amplifier in the event of detuning of the bridge to a servomotor which adjusts both the sensor and the lens holder with the lens to balance the bridge, and thus also adjusts the focusing of the lens. The difficulties and disadvantages of direct measurement of the image distance from the lens are eliminated due to the fact that apart from measuring the subject distance the sensor also simultaneously measures in conjunction with the adjustment of the lens the change thereby caused in the image distance and adds this measured value to the measured value of the sensor for the height adjustment of the projection head.

Title: Percussion drilling machine with percussion rate independent of rotary speed
Inventor: CUNEO GUISEPPE
IPC: B25D16/00
Filed: 1983-04-27
Abstract: In a percussion drilling machine, the percussion mechanism contains two toothed ratchets (19, 20) which are rotatable relative to one another. The drilling spindle (11) can be driven at least at two different speeds. One ratchet (19) is formed on one side of a first gear (13) which is located in a freely rotatable manner on the drilling spindle (11) and is rotated at constant speed irrespective of the speed of the drilling spindle (11). A second gear (14) preferably rotates with the drilling spindle (11) and can be moved axially along the latter between a first position and a second position. In its first position, the second gear (14) rotates in synchronism with the first gear (13), whereas in its second position it is in such a drive connection that it drives the drilling spindle (11) independently of the first gear (13). The percussion rate is advantageously kept constant at different speeds of the drilling spindle (11). <IMAGE>

Title: Combined gas turbine-steam turbine system or gas turbine system
Inventor: WIESER RUDOLF DR
IPC: F02C1/04
Filed: 1983-11-30
Abstract: The invention relates to a combined gas turbine-steam turbine system with a waste heat steam generator, supercharged on the flue gas side and - preferably - not fired, or a pure gas turbine system with a recuperator supercharged on the flue gas side, which have a high efficiency at rated load, improved partial load efficiency and reduced system costs and an increased power limit. For improvement of the efficiency of the combined process a modified steam circuit is proposed with 180-250 bar pressure, fresh steam superheating, recuperative pre-heating of the feed water to approximately 200 DEG C and double moisture separation from the working steam between the housings of the steam turbine. Reduction of the system costs is achieved by a reduction of the heating surfaces of the waste heat steam generator or the recuperator, which is possible because the steam generator or recuperator are at excess pressure on the flue gas side during operation. (This amounts to approximately 4 bar at rated load). Improved partial load efficiency levels are made possible by a reduction of the gas throughput weight through the gas turbine by means of a reduction of the speed of the low-temperature gas turbine set. Finally an increased power limit is obtained by multiple arrangement of low-temperature gas turbine sets. <IMAGE>
