Patent DE-3117399-A1 (DE)
Inventor: HUSCHKE BRUNO ING GRAD
IPC: B01D35/14
Filed: 1981-05-02
Abstract: A filter testing device has a filter housing which has an air inlet and outlet and receives the filter. An inlet line is connected to the air inlet. An inlet valve for the inlet line is controlled to produce a continuous and evenly increasing air pressure therein and an electronic pressure sensor monitors the air pressure therein. An electronic evaluating and control circuit has a time switch, an adjustable threshold device and a peak pressure detector, and controls the inlet valve, a vent valve connected to the inlet line, and a recording mechanism. The air pressure in the inlet line is increased until it reaches a preset pressure. The inlet valve is then closed for the time period set on the time switch. Thereafter, air is again supplied to the inlet line until no further pressure increases are detected by the peak pressure sensor.

Title: Method and system for detecting an aerosol, such as smoke, in a gaseous medium
Inventor: MALINOWSKI WILLIAM J
IPC: G01N21/27
Filed: 1981-05-05
Abstract: The invention relates to a self-calibrating dimming smoke detector and to a method of operating such a detector. In this case, a light source and a photodetector are arranged in a spatial relationship to one another. The output signal of the photodetector is a function of the quantity of light which the detector detects from the light source. The analog output signal of the photodetector is converted with the aid of an analog-to-digital converter into digital signals which are then transmitted into a digital processor which is capable of periodically calibrating the detector and of carrying out the operations of taking samples or scanning between calibrations. Other sensing devices can be connected to the system, in which case the automatic self-calibrating properties are referred thereto. The use of two photodetector cells which detect the light directly from two separate light sources or indirectly from a single source produces a thermally stable system in which one cell supplies a reference output signal for the other cell.

Title: Bracing apparatus for sheet-metal parts, in particular cutlery
Inventor: WALTER KONRAD ING GRAD
IPC: B24B41/06
Filed: 1981-08-21
Abstract: The invention relates to a bracing apparatus for sheet-metal parts, in particular pressed, stamped and/or forged cutlery parts, which are to be machined on their contour. The apparatus has at least one workpiece rest and at least one clamping device which presses the workpieces against said rest and has at leat one retaining part to be placed onto the workpieces. The object of the invention is to provide an apparatus, of the type described in the introduction, which, in a cost-effective manner, permits the contours of a multiplicity of stamped, pressed or forged workpieces to be machined correctly and simultaneously. The invention achieves this object in that the workpiece rest and/or the retaining part have, for the purpose of simultaneous bracing of a multiplicity of workpieces to be machined simultaneously, a corresponding number of spaced-apart individual grooves in which a workpiece is to be placed in an upended manner in each case. The grooves of the workpiece rest permit a "spaced apart block formation" of a multiplicity of identical workpieces. These can thus be aligned such that their contours are parallel and be machined on their edge in a single operation. <IMAGE>

Patent DE-3147787-A1 (DE)
Title: Combined locking and differential steering
Inventor: FREY HELMUT DIPL ING
IPC: B62D11/24
Filed: 1981-12-03
Abstract: In order to save space for the locking wheels of armoured wheeled vehicles having more than two axles, a combined steering is proposed in which only a part of the wheels is slightly locked. As a result, bends with a large radius can be travelled round in a conventional manner for wheeled vehicles. In tighter bends, the vehicle is steered with a steering gear, as is customary in track-laying vehicles, by means of different speeds of revolution of the wheels on the two sides of the vehicle. The lateral space which is saved permits the useful space to be increased or the vehicle width to be reduced. An embodiment of the steering for the example of a multi-axle vehicle is illustrated in the figure. <IMAGE>

The first piston (15) is provided on the inside with an axial drainage duct, one end of which is connected to the first non-return valve and the other end of which is connected in the operating position to the filling element of the hydraulic unit to be filled. In addition the pump has an inlet orifice (28) with a second non-return valve (32), which is attached to the end of the low pressure cylinder chamber (30) remote from the first piston. The high pressure cylinder chamber (18) is formed inside the first piston (12). Into this high pressure cylinder chamber (18), at its end remote from the low pressure cylinder, a second piston (46), fixed in relation to the cylinder and arranged parallel to the axis of the first piston, is introduced. Both pistons (12, 48) are designed as plunger pistons. In the case of this pressure-increasing piston pump provision has to be made for a friction seal only on the one end of the high pressure cylinder. The high pressure cylinder, moreover, requires finish-machining only on one short section. <IMAGE>

Title: Method, arrangement and circuits for nondestructive testing of the wheel treads of railway wheels by means of ultrasonic surface waves
Inventor: SALZBURGER H JUERGEN DIPL ING
IPC: G01N29/24
Filed: 1982-05-15
Abstract: Nondestructive testing of the wheel treads of railway wheels without disassembling the wheel sets is served by ultrasonic surface waves which, emanating from test heads integrated in the rail heads, propagates as the wheel rolls over along the wheel tread thereof and after passing through the wheel circumference or after reflection on the propagation path, e.g. at a crack, are received by the test heads and subsequently evaluated. The test heads consist of electromagnetic ultrasonic transducers having premagnetisation and radio-frequency coils, accommodated in recesses in the rail heads, for exciting the surface waves, without the use of coupling means, in the over-rolling wheel and for receiving the waves which have passed round or been reflected. A plurality of power transistors each operating in push-pull B operation, serve to generate the RF pulses. Located in the receiving path is a logarithmic wide-band amplifier, in which a plurality of logarithmic stages are driven in a stepped fashion by limiters, amplifiers and attenuators and are interconnected on the outward side by a summer.

Patent DE-3303080-A1 (DE)
Title: Grinding bowl drive and mounting
Inventor: FISCHER HELMUT ING GRAD
IPC: B02C15/00
Filed: 1983-01-28
Abstract: The invention relates to the drive and the mounting of the grinding bowls of roller mills with a vertical axis of rotation. In contrast to the conventional construction, the drive gears and the mounting of the grinding bowl form separate units. The mounting of the grinding bowl, with the particularly strongly constructed axial bearing, rests on its own support structure intended for this purpose. The drive gears serve only as the drive of the grinding bowl and must not receive any outside forces. Hence, they can be specially designed for this task, so that they can be kept small enough for there to be space for them within the support structure. As a result of the separate formation of the support structure for the mounting of the grinding bowl and gears, each individual unit is simpler, and thus correspondingly lighter, per se. Transport and mounting are thus simplified. <IMAGE>
