The processor can be used for dough-kneading, shaping pasta into noodles etc., or for cutting fruit and vegetables into chips etc., all according to the processing matrix used.
Patent DE-2903559-A1 (DE)
Title: Automatic control circuit for solar cell output - has DC=DC converter between cell and load to maintain cell at optimum voltage point
Inventor: KIENSCHERF ECKHARD
IPC: H02J7/35
Filed: 1979-01-31
Abstract: Use is made of the characteristic of a solar cell which is that the optimum operating voltage for maximum power output has a constant value over a wide range of cell illumination. The solar cell voltage (U) and a reference (Uref) are applied to a differential amplifier whose output is used to adjust the operating point of a dc to dc converter. The load is connected to the converter output. The reference voltage is equal to the optimum cell voltage. Any error between reference and actual cell voltage thus gives an output from the differentail amplifier which adjusts the converter operating point to a position where the cell is again operating at its optimum voltage. Thus for fixed voltage output to the load the cell current can be adjusted to give optimum power output.

Title: Ultrasonic thin wire welding - by vibrating bonding tool with minimum reduced active mass
Inventor: BANSEMIR MANFRED DIPL ING
IPC: H01L21/60
Filed: 1979-07-18
Abstract: An appliance to join wires to modules on semiconductor devices by ultrasonic vibrations is fitted with a bonding arm on which the vibrator and the bonding tool are mounted. This is hinged to a parallel support arm carrying a magnet for the adjustment of wire tensioning clamps which are also mounted on it. This reduces considerably the mass of the parts, which act on the wire, reduced to the point of application of the bonding tool. The wire is not deformed and all joints are well reproducible. Thinner wire gauges can now be processed satisfactorily.

Title: Rough board cutting machine cross conveyor section - has additional offset capping jaw moving upwards ahead of fixed one
Inventor: BERTRAM DIETER
IPC: B27B5/22
Filed: 1979-08-24
Abstract: Boards or beams, with original rough edge, are conveyed from a sawing machine to an edge trimming device, with intermediate treatment on a transverse conveyor by a capping saw cutting off end pieces which protrude sideways from this section. The section (1) contains a further capping saw (8), in front of the stationary one (4) and offset inwards from it. This swivels up from a rest position below the wood support level (B) into an operative position for the wood lying on this. In this position it is movable against the transverse conveyor sections conveyance direction, at least across the max. width of the boards or beams. Operation at the board end is made easier, and the flow of material is accelerated.

Title: Removable in-line filter for piped liq. partic. milk
Inventor: BULLOCK GEORGE PETER
IPC: B01D29/96
Filed: 1979-09-08
Abstract: Filter comprises a hollow body with a slot into which a sliding member can be inserted and withdrawn. The sliding member is fitted with a filter element which is made operable by inserting the sliding member. The member is a push fit in the slot so that the assembly is made leakproof simply by insertion of the member. The member pref. has an O-ring on each of its opposite faces, around the element. The O-rings provide a leakproof seal between the sliding member and the filter body. When the sliding member is inserted in the body it pref. provides a restricted by-pass in parallel to the passage through the filter element. The body is pref. made of a transparent plastic such as nylon so that the element can be viewed through the body. Filter is used specifically to detect clots in milk flowing through a pipeline, esp. from a milking machine, so that clotting problems can be related to specific animals. It is easily fitted in individual lines of a milking machine. Clotting can be observed through the body without withdrawing the filter element. Milk can continue to flow even when the element is completely blocked.

Title: Thermoelement temp. sensing measurement circuit - compensates thermo-element variations from measurement of resistance as well as thermo-voltage
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G01K7/02
Filed: 1980-02-22
Abstract: The temp. measurement arrangement is associated with a thermoelement and a measurement circuit (3) and performs automatic measurement of and correction for the variations in characteristics of the thermoelement during operation. This is achieved without necessitating that one of the active measurement conductors of the thermoelement be wound as a coil. The arrangement ensures enhanced indication reliability by the use of redundant information, namely the thermal wire resistance as well as the thermovoltage. This is achieved by using a monitoring circuit (4a) connected to the thermal wires (1a,1b) of the thermoelement (1). The thermoelement wires are connected via a change-over switch (2) alternatively to the temp. measurement circuit (3) or the resistance measurement circuit (4a). The two measurement circuits (3,4a) are connected via an evaluation circuit (5) The direct or alternating current impedance may be monitored.

Title: Analogue channel switching unit - uses selectors addressed by computer to couple with single A=D converter
Inventor: RENNER PETER ING GRAD
IPC: G06F3/05
Filed: 1980-04-10
Abstract: An analogue switching system allows a large number of channels to be addressed and the signals processed by an A/D converter to provide an input to a computer. The system has several analogue channel switching stages (3,4), each receiving signals from a number of channels (9,10). The computer (1) has an address bus (7) that communicates with the analogue to digital converter (2), the channel selectors (3,4) and output stages (5,6).
