Title: Three-way pilot-control valve closed only in the rest position
Inventor: NEFF JAMES AUGUST
IPC: F16K31/06
Filed: 1981-08-04
Abstract: A three-way pilot-control valve (10) closed only in the rest position for supplying a fluid-flow control valve, for example a four-, three-, two-way directional control valve or the like, with operating compressed air for adjusting the main control spool of such valves has a valve housing (11) with an inlet port (13) for operating compressed air, a cylinder connection (21) and an outlet port (28). The inlet port is connected via a first channel (groove 14, bore 15, passages 19, groove 20) to the cylinder connection (21), which is connected to the outlet port (28) via a second channel (bore 24, passages 25, outlet chamber 26, channel 27). In the valve housing (11), a disc control slide (39) is movably arranged between a rest position in which it blocks the first channel (14, 15, 19, 20) and a working position in which it opens the first channel (14, 15, 19, 20) and blocks the second channel (24, 25, 26, 27). The disc control slide (39) can be put back into the rest position by a resetting device (resetting spring 41, air channel 42) acting by spring force with air assistance and can be moved into the working position by an electromagnet. The disc control slide (39) is provided with only one dynamic sealing member (50). The pilot-control valve (10) has two sharp-edged valve seats (47, 48) arranged at a distance apart in the longitudinal direction on which two annular valve closure members (45, 46) arranged at a distance apart in the longitudinal direction can be brought to bear alternately against the disc control slide (39) when the disc control slide (39) is moved between the working and rest positions. <IMAGE>

Title: Mixer, preferably for liquid components
Inventor: LAGEMAN HUBERT R PROF DR
IPC: B01F5/06
Filed: 1981-09-29
Abstract: Known mixers are stirred mixers (only batchwise operation is possible) and static mixers (high transfer pressures are required). It is the object of the invention to eliminate the above disadvantages in mixers for liquid components. The object is achieved when the liquid components flow through a three-dimensionally moving mixer element arrangement. Figure 1 shows that the components enter an inlet part (1) which is at rest, then flow through an elastic adaptor (4), are subsequently mixed by the mixer elements (5), flow in the mixed state through a further elastic adaptor (4) and leave through an outlet part (7) which is at rest. The mixer elements (5) and, on one side, the elastic adaptors (4) are rigidly coupled to the vibrating plate (2) by means of two holding rings (3) and a spacer ring (6). The vibrating plate (2) is driven by one unit or a plurality of units in such a way that all parts of the mixer elements (5), through which the liquid components flow, execute the same exact three-dimensional motion. <IMAGE>

Title: Armchair with foot support
Inventor: MEYER HELMUT
IPC: A47C1/034
Filed: 1981-10-02
Abstract: In armchairs with pivotable foot supports, formally satisfactory solutions have not previously been disclosed. The known adjustment mechanisms for foot supports are voluminous and complicated. The multipurpose character of known reclining armchairs can often be seen even when the foot support is folded away. When the foot support is opened out, the lever mechanism is always an interference. In the armchair according to the invention, a very simple actuating linkage is provided which is attached in the centre below the pivotably hinged foot support and consists of one actuating lever (9) which couples the lower end of the inclinable backrest (3) to the foot support (10). <IMAGE>

Title: Centring device for compactly stackable pallets for receiving drums preferably containing radioactive waste
Inventor: HEMPELMANN WILHELM
IPC: B65D19/08
Filed: 1981-11-28
Abstract: The invention relates to a centring device for compactly stackable pallets for receiving drums or containers of radioactive waste, having a frame for receiving the drums and at least one stanchion attached thereto for stacking the pallets one above the other. The purpose of the invention is to provide a pallet, in which simple positioning of two pallets one above the other is allowed by a special centring device. For this purpose, the stanchion or one of the stanchions has a greater length than the height of the drum and than the length of the other stanchions. Mounted on the underside of the pallet below the one stanchion and central thereto is a funnel-shaped conical stacking recess with an opening which is widened at the bottom, the upper inside diameter of the stacking recess corresponding to the outside diameter of the stanchion for receiving it. Inserted between the stacking recess belonging to the stanchion and the lower end of the stanchion is a hollow cylindrical transition piece, whose length corresponds to the stanchion elevation and in whose inside diameter the stanchion just fits with its elevation. It is advantageous in the present invention that, when stacking two pallets one above the other or placing the upper pallet on the lower pallet, the driver, for example of a fork lift truck or a crane, only has to pay attention to the centring of the upper longer stanchion. He allows the pallet to be placed on top to be lowered onto the longer stanchion of the lower pallet and turns it until it has assumed the correct position for stacking.

Title: Machine for setting up pins on a pin deck, in particular in the case of skittle or bowling alleys
Inventor: WAGNER KARL-HEINZ
IPC: A63D5/08
Filed: 1982-04-21
Abstract: In the case of a machine for setting up pins on a pin deck, in particular in the case of skittle or bowling alleys, after each throw the pin deck is completely cleared; then pins corresponding to the pins remaining standing are set up on the pin deck. For this purpose, the pins originally remaining standing are determined, in particular by an ultrasonic measurement. For this purpose, an acoustic transducer for each pin is aligned with it. A filling device for refilling the magazine has a device which contactlessly determines the actual value of the transfer location of the filling device. For this purpose, at the displaceable element of which the actual value is to be determined, an induction element is arranged continuously inclined outside an induction coil alongside the latter. The frequency of an LC circuit, in which the induction coil is connected in a frequency-determining manner, serves as a measure of the actual value. <IMAGE>

Title: Method for regulating drying processes
Inventor: HEINZE CHRISTOPH
IPC: F26B25/22
Filed: 1982-04-29
Abstract: A method for regulating and controlling drying processes is described, in which a water-containing finely divided solid is brought into contact with a heated drying gas in co-current flow. The temperature, the relative humidity and the quantity of the drying gas before heating, as well as the specific humidity of the solid to be dried and the pressure in the drying zone are measured, the temperature and relative humidity of the drying gas as well as the required specific humidity of the dried solid are specified, from these values the quantity of the dried solid and the temperature of the drying gas on entering the drying zone are calculated, and, using the calculated values, the supply of moist goods and energy to the drying zone is controlled. The energy consumption required per kilogram of evaporated water is also calculated and optimised by changing the specified values. The method results in uniform product quality and favourable energy consumption in spite of fluctuating operating parameters.

Title: Position sensor for determining the position of linearly displaceable machine parts
Inventor: UEMANN GERHARD
IPC: G01D5/245
Filed: 1982-11-27
Abstract: Incremental position sensors for determining the position of linearly displaceable machine parts having a coding element and an associated scanning device which move relative to one another as a function of the displacement path of the relevant machine part are known. A fixed point in the displacement path for the absolute determination of the path must be provided in this case by additional devices. In order to shift the fixed point of the displacement path in the position sensor itself, the coding element and the scanning device are coupled to a second coding unit, comprising a coding element and scanning device that can be moved relative to one another in such a way that the second coding element and thus its marking along the displacement path are scanned only a single time.
