Title: Hydrolytic decomposition of starch in agricultural prods. - by steam heating batches of an aq. mash of the prod., then cooling, using the heat extracted to heat the next batch
IPC: C13K1/06
Filed: 1979-09-15
Abstract: In a process for hydrolytic degradation of starch in agricultural prods. by pressure steaming individual charges of heated process water and the prods., the mash is heated to the desired temp. and maintained at this for a period which depends on the temp. achieved, to promote the hydrolysis reaction. Before releasing the material to atmospheric press., it is subjected to a cooling phase, during which the hydrolysis is continued. The heat extracted by the cooling is used to heat the process water for the next charge of mash. The process is useful for conversion of starch in cereals, potatoes, root crops, etc., into dextrins, e.g. for subsequent conversion into alcohol. The present process reduces the hydrolysis time and reduces energy consumption by utilizing the heat from one batch to heat process water for the next.

Title: Continuous bar pattern transverse motion measurement - detecting analogue signal using offset alternating signal transducer outputs differentiated and logically combined
Inventor: STECHER HELMUT DIPL ING
IPC: G01D5/245
Filed: 1980-01-11
Abstract: The method and arrangement are for the measurement of transverse movement of bar patterns and involve the use of two pattern scanning transducers giving output signals of constant alternating amplitude mutually offset in the direction of transverse motion. An analogue approach is used which results in approximately continuous transverse measurement. This is achieved without time delays and with directional dependency. The transducer output signals A and B are combined into logical parameters V1 and V2 by addition, subtraction, differentiation, and multiplication. V1= (A+B).d(A-B)/dt V2= (A-B).d(A+B)/dt The logical parameters can be integrated against time to produce a parameter proportional to the transverse motion amplitude. Alternatively they can be differenced to produce a parameter proportional to the speed of the motion.
Patent DE-3005328-A1 (DE)
Title: Video recorder with static head assembly - uses one head for each direction of tape movement
Inventor: WELLHAUSEN HANS
IPC: G11B5/008
Filed: 1980-02-13
Abstract: In order to simplify the mechanics of video recorders an arrangement is used where the video tape which is multi tracked is moved at the full speed of about 20 m/sec as many times forward and backwards as there are recording tracks. The difficulty of obtaining a near-instantaneous inversion of tape movement is solved by the provision of two heads one for each direction of tape movement mutually offset by one track pitch. The capstan wheels are hollow and tiny holes pass air suction or air pressure to the active surface enabling a rapid change-over of pulling action. The capstans rotate in opposite directions. Acceleration forces are buffered by spring loaded idler rollers. The system functions correctly when during the transitional period the tape opposite one head passes at the same velocity in one direction as the tape opposite the other head passes in the opposite direction. During this phase which lasts only a very short time the electronic connection to the heads is switched over, after which the tape at the disconnected head looses its capstan drive, and unidirectional tape speed is restored.

Abstract: Pressbutton sections (D) are marked on the top layer (1) insulating cover of the key pad switch which has a rigid insulating material support (2) under it. The support material (2) has a shouldered cut-out at each press button position (D) to accommodate a rigid insulating material (3) shouldered piece on the top layer underside. The insulator (3) can be pressed down (D) until the shoulders meet (4,10) on the press button insulator (3) and rigid underlayer support material (2). The switch contact layer of the sandwich comprises an insulating layer (5) under the rigid insulator sections (2,3) with a contact material (6) at the press button positions (D) on its underside. These are above the base material (8) contacts (7) with which they make. A foam separator insulating material (9) maintains the spacing between contacts (6,7) in the 'off' position and collapses at the edges when a press button is operated. The feature is the shouldered stop (4,10) incorporated in the top sandwich.

The two units are connected to one another and to the gas generator by gas lines. For ignition of the combustion chamber of the gas generator and for actuation of the compressor and a valve an electrical line runs from the ignition unit of the motor vehicle to the gas generator, to a thermostat in the gas generator, to the compressor and to the valve. The gas line and the electrical line are laid in a common line from the motor vehicle consumer or ignition unit to the trailer which can be separated by a coupling in the area of the trailer coupling. <IMAGE>
