Title: Method and arrangement for generating pixel signals
Inventor: LUX PETER DR
IPC: H04N19/60
Filed: 1981-03-11
Abstract: To reduce the amount of information during the transmission or storage of images, it is known that these can be transformed and the coefficients produced can be quantized. For the transformation, the images are split into subimages and multiplied by a transformation matrix. In orthogonal transformations using a fast transformation algorithm, this can be reduced by a successive multiplication with basic matrices. Starting with a sequence of the coefficients produced during this process, a method is described to generate inversely transformed images at a reduced scale, for example for simultaneously representing an overview of a number of images next to one another on a viewing area. For this purpose, only every second, fourth and so forth of the coefficents in the said sequence of coefficients is in each case used in accordance with the scale of reduction and the image is inversely transformed in a number of steps. As a result, each pixel in the inversely transformed image corresponds to the mean value of a number of pixels of the original image depending on the scale of reduction. <IMAGE>

Title: Auxiliary power steering system for motor vehicles
Inventor: ELSER DIETER ING GRAD
IPC: B62D5/30
Filed: 1981-03-14
Abstract: In an auxiliary power steering system having two steering circuits which are independent of one another, the first steering circuit (7) is connected to a small servo motor steering gear unit (6) and is supplied by means of a travel-dependent servo pump (5). The second steering circuit (9) is connected to a separate larger servo motor (12) which is connected to the steering gear, and the said steering circuit (9) is supplied by means of an engine-dependent servo pump (11). The build-up in pressure in the first steering circuit (7) takes place more rapidly than in the second steering circuit (9). The first steering circuit thus assumes the greater part of the steering work in the travel range with relatively low servo forces while the second steering circuit (9) is assigned to the parking and steering range with relatively high servo forces. <IMAGE>

Title: Pressure control valve for vehicle hydraulic brake systems
Inventor: REINARTZ HANS-DIETER
IPC: B60T11/34
Filed: 1981-03-24
Abstract: In a pressure control valve for vehicle hydraulic brake systems the sealing piece (19) is carried by a control piston (14), which is guided with one end through a ring packing (15) and in a bore (12) of a housing (4) and at the other end carries a support plate (16) for the action of a valve spring (17). The valve seat (20) is formed by the inner annular area of the rim of a torus (21), which is held elastically yielding between the housing (4) and the inner flange of a tubular body (10) fixed to the housing. An outer annular area (26) of the torus (21) bearing on the inner flange (25) forms a return flow valve (27). A thrust ring (29) axially displaceable by the support plate (16) presses on to the rim of the torus (21) between inner and outer annular area when the control piston (14) somewhat exceeds the normal closing stroke (b). In this way the return flow valve (27) can reliably open at a very early point when the inlet side pressure falls below the outlet side pressure. <IMAGE>
Patent DE-3119881-A1 (DE)
Inventor: BIERI HANS
IPC: B23D17/06
Filed: 1981-05-19
Abstract: In shears for rod-form material, especially in connection to roll trains, the problem exists of a space-saving construction, especially in the sidewise direction, in view of the multiple arrangements, as well as increased safety (reliability) of operation for the high-pressure hydraulic system of the cutting drive. The shear provided with two knife holders (MT1, MT2) and a fluid drive element (ZK) as well as a respective pressure feeding device (DS), is so designed, for this purpose, that the pressure work chambers (DA1, DA2) of the drive element, such as a double-acting cylinder-piston arrangement, and the elements carrying pressure fluid (high-pressure pumps, etc.) of the pressure feeding device (DS) are designed to be movable in common with a knife holder (MT1) which is movable in relation to the machine frame or a conduction (SF) of material to be cut, and preferably fixed in space with this latter (MT1).
Patent DE-3121849-A1 (DE)
Title: Plaster carrier/insulating panel
Inventor: REICHENBERGER MATHIAS
IPC: E04F13/00
Filed: 1981-06-02
Abstract: The currently conventional insulation for exterior walls with construction materials which have a high insulating capacity results, particularly in the case of the structural parts located on the sunny side, in a heat and diffusion accumulation which then often leads to damage to the plaster. The invention eliminates this shortcoming by configuring a multi-layer panel, e.g. a polystyrene or PU foam panel coated with a wood wool/cement mixture, such that ventilation ducts permitting the heat to escape run (Z1) immediately behind the plaster-carrier layer, which is even less effective in terms of insulation. With particularly high exposure to heat, the design according to Z5, in which smaller horizontally running ventilation ducts adjoin the vertically running ventilation ducts, is possible. If the ventilation ducts are to be used as hot-air supply for heat pumps, this being readily possible by combining the ventilation ducts at the upper masonry-work end by a pipeline running around them, then a corresponding, larger design of the ventilation ducts is expedient.   <IMAGE>

Title: Device for cutting off turned metal parts
Inventor: WIENEKE LORENZ
IPC: B23B29/04
Filed: 1981-06-24
Abstract: A thin cutter disc (4) with a basic circular shape and cutting teeth (5) projecting at the periphery is secured interchangeably in a holder (3) of the cut-off device. On the workpiece side, the holder (3) has a pitch-circle-shaped cut-out (7), in the area of which the cutter disc (4) is exposed with a cutting tooth (5) carrying out the cutting-off operation. In the process, the holder (3) with cutter disc (4) is displaced transversely to the axis of rotation of the workpiece (1) and the turned workpiece (1) is cut off from the material (2). The cutter disc (4) can be fixed in position by fixing pins (8) and centring collar (10) on both sides of the holder and is held on the holder (3) by an elastic, plate-like clamping disc (11) with threaded bolt (12) and nut (13). When the nut (13) is tightened, the clamping disc (11) acts on the cutter disc (4) with favourable clamping forces, which, especially in the area of the holder cut-out (7), avoid fluttering of the cutter disc (4) during the cutting-off. When a tooth (5) is worn, the cutter disc (4) can be adjusted (rotated) after slackening the nut (13) and clamping disc (11) and an unused tooth (5) comes into the holder cut-out (7). Due to the thin cutter disc (4), minimum material loss arises during the cutting-off, which results in exceptional cost-effectiveness and efficiency. <IMAGE>

Title: Shock absorber for the damping in conformity of wheel and body vibrations in vehicles
Inventor: HOEFER LOTHAR ING GRAD
IPC: B60G15/02
Filed: 1981-08-27
Abstract: The invention relates to an arrangement of shock absorber elements and springs, which are fitted between the body and the wheel suspension of vehicles. By means of this arrangement wheel and body vibrations, which usually have greatly differing natural frequencies, are each respectively damped in conformity. The transmission of road surface impacts is thereby reduced and the wheel contact with the road is improved. The arrangement basically comprises a damper element with a hard damper characteristic, which damps the body vibrations, and a damper element with soft damper characteristic, which is intended for the damping of wheel vibrations. The arrangement also includes a spring of suitable size, which is arranged in series with the harder damper element. Due to the action of the spring the harder damper element is virtually ineffective for higher frequency vibrations. The wheel vibrations have the higher frequencies and can be damped with a softer damper element. A compact construction of the three main elements (two shock absorbers and one spring) is possible. The design principle for this is indicated in the patent.

Title: Boiler draught regulator
Inventor: VOLLMER RUDOLF
IPC: F23N3/04
Filed: 1981-11-05
Abstract: To safeguard against excess temperatures, a boiler draught regulator is equipped with an additional safety thermostat in series with the actual control thermostat. Arranged in the control thermostat is a support pipe in order, in the event of failure thereof, to limit the length reduction. The safety thermostat is selected in such a manner that its working element only undergoes a displacement when the regulating range of the control thermostat is exceeded. Moreover, the safety thermostat has a very steep distance/temperature characteristic and its maximum travel is selected to be equal to or greater than the travel which an operative control thermostat carries out over the entire regulating range. Also provided is a locking device which, when the safety thermostat has been actuated, prevents the incoming air flap, which has been operated in the closing direction, being opened again.

Title: Electromagnetic relay for pulse operation
Inventor: KUPEC PETER DR
IPC: H01H51/22
Filed: 1981-11-05
Abstract: The pulse relay has a winding (3) whose volume is reduced in comparison with the winding volume which is required because of the maximum permissible heating when the coil is permanently energised. A predetermined pulse-pause ratio (a/b) is used to ensure that the permissible temperature of the coil is not exceeded during the pulsed heating. In a preferred embodiment, the small winding space of the relay permits the advantageous arrangement of the coil within a frame-shaped armature (6), polarised permanent magnets being arranged in the radial direction between the coil winding (3) and the armature (6). <IMAGE>

Title: Process for the colour reproduction of coloured originals
Inventor: MADER ARTUR DIPL CHEM
IPC: G03F3/08
Filed: 1981-11-17
Abstract: In a process for the colour reproduction of coloured originals, the original is photoelectrically scanned point-by-point and, after digitisation by a computer, the analogue signals obtained in this way are compared with corresponding values obtained by scanning a printed colour matrix. The data resulting from the comparison control a recording device which either produces directly one or more printing forms or exposes one or more colour separation negatives or positives. In this process a colour matrix is used whose coloured areas have been printed using not more than two of the three chromatic colours cyan, magenta and yellow and, optionally, black. The invention achieves the result that not more than three colour layers are printed one on top of the other in the subsequent printing process.
