Patent DE-2552437-A1 (DE)
Title: Associative memory for character and voice recognition - has analogue memory cells for parallel or serial modes for statistical probability interpretation of distorted transmission signals
Inventor: WILLWACHER GERD DIPL ING
IPC: G06V30/194
Filed: 1975-11-22
Abstract: An associative memory system is based upon analogue modules and designed for both parallel and series modes of operation. It is intended for sample interpretation in automatic character and voice recognition systems. A point matrix of analogue cells generates the most probable output signal pattern in response to an input signal pattern. Each cell has a feedback loop with a transfer function and the sampling stage sums all outputs from the cells to generate a signal that is processed over two proportional amplifiers. The individual cells consist of an amplifier, a summing function, delay and PD stage. When parallel associative operation alone is called for, the PD stage is unnecessary.

Title: Fully enamelled IC engine exhaust gas silencer - is of absorption type and made in sections with peripheral flange connections
Inventor: BAUMANN WERNER DR ING
IPC: F01N13/18
Filed: 1975-12-20
Abstract: IC engine exhaust gas silencer is of the conventional absorption type but has the casing (3) made in at least 2 parts (11,12) with peripheral flanges (13,14) and embodying a length of the central pipe (7,8). The parts are completely enamelled, except for the end of the central pipe which is threaded externally to take a coupling sleeve (10). When the silencer is assembled a joint is made between the flanges in such a way as to avoid damage to the enamel, by rolling a sleeve (15), pref. of alloy steel, around the outside. Sealing can be improved by a layer of softer material, e.g. copper, between sleeve and flanges, or by a gasket of heat-and corrosion-resistant material between the flange faces. The faces of the flanges may be ground flat.

Title: Axial force transmission for rotating clamping tools - has workpieces clamped centrally in hollow shaft with thrust bearing and radial piston channels
Inventor: MOOSMANN JOSEF
IPC: B23B31/16
Filed: 1975-12-27
Abstract: The clamping arrangement consists of a number of stationary, axially-mounted air cylinder-piston units (1). The piston rods of these units exert a force against one side of a thrust bearing (3). The force is transmitted by the thrust bearing to a number of axially-mounted hydraulic cylinder-piston units mounted in a rotating frame. The fluid forced out of these cylinders flows via ring channel in the end of the cylinders to a number of radially-mounted piston-cylinder units (9) with which the work-piece is clamped. As all cylinders are interconnected, equal pressure is exerted on each piston.

Title: Externally controlled transistor DC converter - has pulse width controlled control transistor and converter delivering control signals from output voltage deviations
Inventor: NICOLAUS ROBERT
IPC: H02M3/335
Filed: 1976-01-28
Abstract: The externally controlled transistor d.c. converter has a pulse-width controlled control transistor. The converter has an LC filter circuit between the rectifier and output of the d.c. converter. A control converter converts the output voltage deviation into control signals. At the converter output a periodic test voltage is generated reproducing the rise of collector current. One of these voltages is compared with the actual value of output voltage, or a sum voltage proportional to the output voltage is compared with a nominal voltage. The comparator delivers signals for blocking the control transistor.

Title: Microphone cover for telephone instrument - consists of three discs with empty and closed surfaces, with middle disc rotatable
Inventor: PETER CLAUS JUERGEN
IPC: H04M1/19
Filed: 1976-06-25
Abstract: The adaptation relates to an additional cover plate to a telephone microphone container. The cover consists of three equal size disks permanently mounted on the microphone mouthpiece in order to prevent the other subscriber from hearing of speech or sounds in the first subscriber room. The lower and the middle disks have an evenr number of equal surfaces, of which each second is made of an impermeable material while the the surface in-between are empty. When the middle disk is rotated by a part of 360 deg., it moves the closed surfaces over the empty surfaces, thus cutting off the communication.

Abstract: Prepn. of mono- or poly-, symmetrical or asymmetrical tert-amines comprises reacting a prim. or sec. amine R1-NH-R2 (where R1 and R2 are each H, alkyl or cycloalkyl gps., opt. substd. by inert substs. which, in turn, may carry amino gps. -NHR1) with mono- or di-hydric prim. or sec. - alcohols. The reaction is catalysed by a hydrogenation/dehydrogenation catalyst, opt. in the presence of H2, and the amine is fed into the liq. reaction mixt. contg. the mixt. of alcohol required for the reaction and the proportion of water formed in the reaction is eliminated. High yields of tert-amines are obtd. with low amts. of prim- and sec-amine contamination. Since the alcohol reactant is completely consumed the sepn. of alcohol from tert-amine, which is usually difficult and energy-consuming, is avoided.

IPC: H01M10/637
Filed: 1976-09-29
Abstract: An attachment to an accumulator such as a starter battery automatically maintains a working temp. which is beneficial to the battery when the ambient temp. is low. An electric heater is in close contact with the battery. Its power supply from the battery is automatically controlled by a thermometer probe which senses the actual temp. of the battery. This facilitates car starting on cold mornings. The new system can be added to any existing conventional batteries. Specifically, the starter battery is put on a heater, consisting of a metal case, a hot-plate, two insulating foils and a heat insulating slab, pref. of polystyrene foam. A thermostat is attached to the battery wall to sense its temp. The system is controlled by a switch on the dashboard.

Title: Prodn. of lubricating oils and greases - using ferromagnetic particles in rotating magnetic field to disperse ingredients
Inventor: KAFAROV VIKTOR VJATSCHESLAVOVI
IPC: B01F13/08
Filed: 1976-12-07
Abstract: Prodn. of lubricating oils and greases by dispersing thickners, additives and fillers in base fluids is carried out by means of ferromagnetic particles which form a vortex under the influence of a rotating magnetic field. The ferromagnetic particles can be of a magnetically soft or hard material (e.g. carbon steel, Ni or Co/Ni alloys) with a ratio of max. to min dimension of 6-20:1. The particles are pref. protected by a polymer coating. In the case of dispersing thickeners (e.g. metal soaps), these can be formed in situ by reaction of appropriate starting materials. High quality products can be produced in treatment times of a few seconds. Energy consumption is low. The process can be operated continuously and is readily automated.

Title: Lock with axially sliding disc - has disc acting with latch and locked by pair of key operated discs with segmental cut=outs
Inventor: BUDACH HEINRICH
IPC: E05B37/00
Filed: 1977-06-24
Abstract: The lock comprises a pair of discs (7), with segmental recesses (76) in their edges, which are rotated independently by a key. The two discs overlap a third disc (67) which may slide axially when the angular setting of the first two discs is such that their segmental recesses correspond with the edge of the third disc. Axial movement of the third disc releases a sliding latch (5). Access to the key apertures is through holes (59) in the latch so arranged that only one of the discs may be tuned with the key at a time. Opening by manipulation is thus impossible. When locked, the latch may slide to a small extent to open one or other of the key holes.
Patent DE-2744468-A1 (DE)
Title: Heat storage system using heat accumulating material - contains transporting medium remaining liq. over entire temp. range
Inventor: MAHDJURI FARAMARZ DIPL PHYS DR
IPC: F28D20/02
Filed: 1977-10-03
Abstract: The heat storage system has one or more reservoirs containing material accumulating heat in the process of changing from the solid to the liquid state, and exchanging heat via a heat-transmitting wall of the reservoir. The latter also accommodates a heat transporting medium separated from the accumulating material by a movable and flexible partition. The partition (9) extends all over the surface of the heat-transmitting reservoir wall (2a) between the latter and the accumulating material (10). The heat-transporting medium is a heat-conductive material remaining in the liquid state over the entire working temp. range, and when the accumulating material sets and consequently shrinks, the medium completely fills any spaces between partition and reservoir wall.
