Title: Hydraulic booster valve, especially for a motor vehicle hydraulic brake system
Inventor: LEINEWEBER GUENTER
IPC: B60T13/12
Filed: 1985-11-28
Abstract: The invention relates to a hydraulic booster valve for a motor vehicle hydraulic brake system, in which only the pedal-side end section of the booster piston projects into the valve housing and a pressure line connection and a return line connection are arranged in that section of the booster piston constantly projecting from the valve housing. In order to reduce the technical manufacturing cost and the axial space required, the valve housing is essentially of sheet metal construction and joined together from a plurality of individual elements, preferably drawn sheet metal parts, a coaxial inner cylindrical sleeve being arranged inside an outer, rotationally symmetrical and approximately pot-shaped housing shell at a radial interval from the latter and extending at least over virtually its entire length, the pedal-side end of which inner cylindrical sleeve is connected to the pedal-side end of the housing shell in such a way that between its outer circumferential surface and the housing shell an annular chamber, closed pressure-tight at the pedal-side end, is formed, into which the pedal-side end section of the booster piston, designed as a cylindrical tube open at the pedal side, is introduced so that it is axially displaceable. <IMAGE>
Patent DE-3542872-A1 (DE)
Title: Loudspeaker enclosure having bent acoustic pipes
Inventor: SCHAEFER DIETMAR
IPC: H04R1/28
Filed: 1985-12-04
Abstract: The invention consists of a number of symmetrically arranged acoustic pipes which are bent away to the rear and which increase the sound pressure in the low-frequency range and widen the frequency range. These are installed in an enclosure which is open at the rear and, due to their arrangement, result in equalised pressure conditions at the rear of the diaphragm and in little generation of standing waves.   This prevents distortion and ensures accurate reproduction quality in accordance with the hi-fi standard. <IMAGE>

Filed: 1986-03-10
Abstract: The invention relates to a mincing machine with a heating and/or cooling device for producing sausage products, in the case of which the sausage meat is cooked in the bowl during the mincing process. The aim is to produce a mincing machine, in which the heating and/or cooling medium is used in a more optimum fashion to reduce heating and cooling times, to improve the quality of the sausage meat and to reduce the outlay on construction. The object is to feed the heating and cooling medium to the material to be processed in such a way that a rapid cooking process is initiated, to permit this to be followed by a rapid cooling process and to optimize the exchange of heating and cooling media. According to the invention, the object has been achieved in that the mincing machine bowl above is designed to be double-walled and the cavity formed in this fashion is divided by ribs into a plurality of chambers, at least two chambers being connected to one another by means of an overflow channel in the ribs. The drive shaft of the mincing machine bowl is composed of a hollow flange for accommodating the feeding and discharging pipes of the heating and cooling media, which flange takes the form of a slide-in part. <IMAGE>

Title: Particulate filter, regenerable by externally applied means, for the exhaust system of a diesel internal combustion engine
Inventor: FINSTERWALDER GERHARD
IPC: F02B3/06
Filed: 1986-11-08
Abstract: The invention relates to a particulate (soot) filter for the exhaust system of a diesel internal combustion engine, the said filter comprising an electrically nonconductive material such as ceramic. In order to ensure the ability to function of a particulate filter, the soot which has been deposited on it must be burnt off at regular intervals. This purpose is served, according to the invention, by connecting to the particulate filter (1) at least one high-voltage electrode (2), associated with which, at a distance, is at least one earth electrode (3) connected to the particulate filter (1). A pulsed high-voltage DC current is applied to the high-voltage electrode, giving rise to spark gaps between the electrodes, the sparks of which burn off the deposited soot and thus regenerate the filter. <IMAGE>

Title: Process for disposing of waste from fat separator units
Inventor: TRAENKLE REINHOLD DIPL ING
IPC: E03F5/16
Filed: 1986-11-29
Abstract: A novel process is presented for disposing of waste from fat separator units, which is characterised in that the separated layer is removed by mechanical means from the waste water surface and then discharged from the separator vessel. Essentially water-free sink and float materials are obtained as a result. The mechanical means can be constructed as a screen grid or flexible link belt. The fat is isolated by pushing off or allowing it to slide off. The still liquid or reliquefied fat can also be absorbed by oleophilic nonwoven webs which are then removed from the separator.

Title: Bush for shafts driven axially with an alternating motion
Inventor: SANTIS GENNARO DE
IPC: F16N31/00
Filed: 1987-02-16
Abstract: A description is given of a bush which comprises a fixed body (2), through which there passes a bore (3) in which there slides a shaft (5) driven with a rectilinear alternating motion. The inner cylindrical surface (4) bounded by the bore (3) has an annular groove (6) at one end (2a) of the fixed body (2). The groove (6) is bounded by two frustoconical surfaces (7a), (7b) which, with the axis of the bore (3), form an acute angle whose apex faces the opposite end to that (2a) mentioned above. The edge formed by the frustoconical surface (7b) with the inner cylindrical surface provides an oil scraper capable of preventing the oil distributed on the shaft (5) to lubricate it from escaping from the bush (1) at the end (2a). A drain hole (8) is formed in the fixed body (2) and through this hole the oil collected in the groove (6) can be drained off. <IMAGE>

Title: Method for reducing a digital noise signal in a digital input signal and circuit arrangement to carry out this method
Inventor: BILLMANN LOTHAR DR
IPC: H03H17/02
Filed: 1987-03-26
Abstract: The invention relates to a method for reducing a digital noise signal and a digital circuit arrangement to carry out this method. A sequence of low-pass-filtered signal values, which are derived from low-pass-filtered signal values determined earlier, and in which values are used which are buffer-stored at a sampling time, is generated from a digital input signal (Xe), comprising a digital useful signal and the digital noise signal. The low-pass-filtered signal (Xr) is used as the output signal (Xa) if the amount of the difference between the input signal (Xe) and the low-pass-filtered signal (Xr) lies within a pre-defined range (G). If the aforementioned amount lies outside the range (G), the input signal (Xe) is used as the output signal (Xa) and all temporarily stored values are replaced by the last input signal value. <IMAGE>
Patent DE-3714523-A1 (DE)
Title: Laser diode having a buried active layer and lateral current limiting, and a method for its production
Inventor: THULKE WOLFGANG DR RER NAT
IPC: H01S5/227
Filed: 1987-04-30
Abstract: In the case of laser diodes having lateral current limiting by means of barrier p-n junctions, the problem arises at high powers that leakage currents make the thyristor structure permeable on the sides of the active layer (4). This problem is solved by the layer sequence of the thyristor structure being partially interrupted by lateral layers (5) consisting of a different material. The material of the lateral layers (5) is selected such that it has a lower energy band separation than the other layers (3, 6, 7, 8, 9) and thus dissipates the leakage currents before they trigger the thyristor. <IMAGE>
