Title: Device for the electro-hydraulic actuation of a clutch locking a power-dividing differential of a motor vehicle
Inventor: GIERER GEORG
IPC: B60K23/08
Filed: 1988-11-25
Abstract: In a device for the electro-hydraulic actuation of a clutch for the purpose of locking a power-dividing differential, an actuating piston (23) is acted upon by a pressure medium as a function of the position of a pressure control valve (11), the said pressure control valve (11) when actuated diverting unpressurised pressure medium to the tank. The power-dividing differential (31) is connected to an automatic transmission on the output side. In order to reduce the design cost, the main control line (4) of the device is connected to the main pressure system (2) of a control (3) for the automatic transmission. Faulty shifting of the clutch (30), which may be caused by system pressure fluctuations and natural oscillations of the pressure control valve (11) are prevented in that a clutch valve (13) in the main control line is connected to the actuating piston (23) on the upstream side, which valve is actuated by a pilot control line (7), which is reduced to a constant reduced pressure by a pressure-reducing valve (5), the pressure control valve (11) and a damping device (20) being arranged in the said pilot control line (7). <IMAGE>

Title: Pick arrangement, consisting of pick and pick holder, in particular for crushing rolls
Inventor: THOMAS PETER
IPC: E21C35/19
Filed: 1988-12-30
Abstract: The invention relates to a round-shank pick with a pick holder which has a cylindrical locating bore for the pick shank as well as additional locking bores passing secantally through the locating bore. The essence of the invention lies in the fact that the locking bore or locking bores are arranged at an angle ( alpha ) relative to the axis of symmetry of the pick holder. This permits reliable mounting of the pick in the pick holder, especially when the pick is loaded axially against its driving-in direction (Fig. 2). <IMAGE>

Title: Piston engine operating method - has silencer chamber containing overlapping pipes forming heat accumulator to maintain exhaust temperature
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N1/08
Filed: 1989-09-06
Abstract: The operating method is for a normally-aspirated multi-cylinder piston engine having intake and exhaust systems increasing the kinetic energy and the degree of oxygen-charging. The final silencer system has a large central chamber (56) containing sets of pipes (541-543) overlapping each other and the outlet pipe (57). These form a sound-dampening structure and a heat-accumulator, so that the incoming exhaust gas in a lengthwise pipe (50) maintains its temperature. At speeds between 4000 and 6000 rpm this causes the exhaust temperature in the manifold to exceed those measured in the individual exhaust branches. ADVANTAGE - Reduced pollution and improved silencing.

Title: Drive, e.g. for sewing machine treadle - has two cables round capstan cable drum as freewheels operated by hand levers
Inventor: SEELIGER KLAUS DIPL ING
IPC: A61G5/02
Filed: 1990-01-12
Abstract: Gearing transmission for a foot pedal or hand lever drive, e.g. sewing machine treadle or a wheelchair drive lever system, has two controllable freewheels. The freewheel control is coupled to the gearing input to be moved. as appropriate. Pref., the freewheels are formed by cables and a cable drum (4), working together on a capstan gearing principle. The same cables (10,11) are used for the drives in opposing freewheel directions. Alternate tautening and loosening actions on the cables (10,11) control the freewheels by (un)winding the cables (10,11) round a rotating tube (12). The upper level tube extension (20) of the winding tube (12) has a cross swing movement to automatically tighten and relax cables (10,11), and the movement of the tube extension (20) to either side gives the forward or reverse drive. If two gearings are fitted, e.g. to a vehicle or wheelchair, an inwards swing of the extension tubes (20) gives a forwards drive and outwards for reverse, while a left and right swing to the levers (20) gives the steering. The hand grip (21) for the tube extension (20) can be pivoted to apply the steering to the wheels through couplings. The cable drum (4) is also used as the braking drum of a drum brake, as the braking is applied by tightening the cables (10,11). ADVANTAGE - System gives a double action freewheel gearing, without a reverse lock, operated by mounting of the drive lever.

Patent DE-4017616-A1 (DE)
Inventor: TUDA NOBUHIRO
IPC: G11C29/24
Filed: 1990-05-31
Abstract: Same test data is written into corresponding memory cells of each subarray of a memory cell array to be read out. A comparing and determining circuit determines whether the data read out from each memory cell has the same logic or not, and the data proves defective when any one of the data has different logic. An output of the comparing and determining circuit is stored in a register to be externally outputted through a predetermined pin (e.g. output enable pin). Timing in which the register accepts the data stored in the comparing and determining circuit is controlled by a switching controlling signal generating circuit disposed in a semiconductor memory device. As the above, all signals necessary for a test are generated in the semiconductor memory device, and the test result is outputted through an existing pin, so that it is structured by the same number of pins as that of a standard semiconductor memory device without a testing function.

Title: Propeller shaft for motor vehicle transmission system - has middle portion of increased dia. to give required natural frequency
Inventor: GREULICH KLAUS DR
IPC: F16F15/32
Filed: 1990-08-29
Abstract: The propeller shaft of a motor vehicle is made in one piece and is of tubular form. The OD of the middle portion (13) is increased with a corresp. increase in tube wall thickness. This has the effect of changing the natural frequencies of torsional and flexural vibration. By varying the length and dia. of the middle portion (13) the natural frequencies can be held within a narrow band, resulting in a redn. of the noise and vibration of the shaft during the operation of the vehicle. USE/ADVANTAGE - Redn. in noise and vibration.

Title: Adsorptive sepn. using microporous adsorbent - esp. travelling strip through which medium flows, useful for immuno:complex formation
Inventor: DEMMER WOLFGANG DIPL BIOL DR
IPC: B01J47/12
Filed: 1990-09-06
Abstract: (A) Adsorptive sepn. is carried out with a flat micro-porous adsorbent which is transported relative to the medium to be sepd., the novelty being that the medium flows through the adsorbent. (B) In adsorptive sepn appts. esp for carrying out process (A), the adsorbent is in the form of a strip which is conveyed over drums while the medium to be sepd is fed by gravity or pressure through the adsorbent. USE/ADVANTAGE: The process is used esp. for adsorption from liq. phases by various (combined) mechanisms such as ionm exchange, hydrophobic interaction, chelate formation and specific interactions such as affinity, chromatography and immuno-complex formation, e.g. for reversible binding of certain enzymes (e.g. malate dehydrosenase) to dyes immobilised on a solid matrix and for heavy metal removal from waste waters.  The process gives high sepn. efficiency since connective material transport occurs within the micropores resulting in accelerated adsorption and desorption compared with the diffusion-limited exchange kinetics of granular adsorbents.
