Title: Roller pressing-on system for paper in thermal printers
Inventor: KLUGE OLAF
IPC: B41J15/04
Filed: 1986-05-20
Abstract: The aim of the invention is to make the visibility and cleaning of the print head possible without demounting it. It is based on the object of providing a roller pressing-on system for paper, which system can adapt to different paper thicknesses, allows immediate readability of the information printed, avoids oblique running of the paper to be printed, and guarantees that the print head is pivoted away from the platen to a great extent. The object is achieved in that two leaf springs 23; 24 are provided, which are connected at one end to the print head carrier 3 and are bent laterally at the other end projecting beyond the print head carrier 3, such that the bent portions 25 are located approximately to the left and right of the line of heating elements, a hole 26 in each of the bent portions 25 accommodating an axle 27 which runs parallel to the platen 2 and on which a pressing-on roller 28 for the paper is mounted outside the bent portions 25. <IMAGE>

Title: Cold-pressure butt-welding machine
Inventor: BRENSCHEDE WOLF DIPL ING
IPC: B23K20/02
Filed: 1987-02-06
Abstract: The subject of the invention is a cold-pressure butt-welding machine with a clamping-jaw and upsetting device. A clamping stroke and upsetting stroke are induced by a single actuating device, the clamping jaws and the upsetting members being moved via an articulated-lever arrangement with angularly mounted articulated levers, and the clamping jaws being arranged on the pivotably mounted upsetting members. The articulated-lever arrangement works on the toggle-lever principle and leads to an increase in ratio of upsetting pressure to clamping pressure, with the result that optimum welding operations are achieved.
Patent DE-3707045-A1 (DE)
Title: Carpet knife
Inventor: PLATTE JUERGEN
IPC: B26B5/00
Filed: 1987-03-05
Abstract: Known carpet knives have the great disadvantage that cutting in corners is difficult for amateurs, as the cutting edge an the thin handle head must be freely guided, making precise cutting impossible, which leads to work which is not clean. The new carpet knife is to be designed in the region of the handle head and the cutting edge in such a way that amateurs, too, are able to cut fitted carpets precisely to size at wall edges without difficulty. In order to permit defect-free wall edge cutting, there are arranged on the handle head (1) two wings (9) which are at an angle to one another and form, on both sides of the cutting edge (5), guiding and contact surfaces (6) for the knife during cutting in the corner (7) formed by two surfaces (8) meeting at an angle (Fig. 3). The guides on the carpet knife make it a tool which is easy to use and which permits amateurs, too, without difficulty to cut fitted carpets precisely to size at wall edges. <IMAGE>

Patent DE-3713527-A1 (DE)
Inventor: BUEDENBENDER BERND
IPC: B23K26/24
Filed: 1987-04-22
Abstract: In order to obtain neat, tight and heavy-duty joints in the butt welding of thin plates or plastic panels, their flanks to be welded together are profiled in a preparatory operation in such a way that not only is stabilisation effected within a plane when joining together: a weld prepared in this way provides an additional positive-locking joint, and the durability of the joint obtained cannot be impaired by slight wandering of the beam of welding energy, since the beam of welding energy always strikes at least profiled elements of both panels to be joined even in the event of deviations.   <IMAGE>
Patent DE-3713911-A1 (DE)
Title: Adjustable valve timing
Inventor: NEUGEBAUER KLAUS JUERGEN
IPC: F01L1/348
Filed: 1987-04-25
Abstract: The control cross-section of the inlet valve after the bottom dead centre is fixed during operation. A large control cross-section of the inlet valve after "bdc" results in a high peak power in the upper speed range and a low torque at low engine speeds. A small control cross-section after "bdc" produces a high torque in the lower speed range for low power in the upper speed range. The new system adjusts the control cross-sections of the inlet valve during operation of the engine. For this purpose, the toothed belt (1), which connects the crankshaft to the camshaft, is lengthened. This toothed belt is also guided by two rollers (2), which are carried by a displaceable shaft (3). In the middle position, the mid points of the rollers, camshafts and crankshafts form the vertices of a rhombus. In a displacement of the shaft, the control cross-sections of the inlet valve are adjusted and the rhombus changes into a triangle. This device can be used in internal combustion engines and in controlling the start of injection in diesel engines. <IMAGE>

Abstract: In a process for the production of printing plates in which a screen film corresponding to the print pattern or the respective colour separation is copied onto the printing plate with a photosensitive coating, tonal value or colour value deviations in the copying operation and in the subsequent printing operation are compensated by masking the printing plate with a half-tone negative copy of the screen film during exposure.
Patent DE-3728110-A1 (DE)
Title: Antenna array
Inventor: SOLBACH KLAUS DR
IPC: H01Q21/22
Filed: 1987-08-22
Abstract: In the case of antenna arrays having regularly arranged aerial elements with individual phase and amplitude adjustment, grating lobes occur as a result of diffraction effects for waves which arrive at the antenna in planar fashion, primarily for frequencies above the operating frequency of the antenna. In order to reduce or overcome these grating lobes, the aerial elements are split into four parallel-connected individual aerials having a common supply point. While the cost of the antenna array is increased only insignificantly as a result of the constant number of individual supply points, half the aerial separation acts for incident waves, so that first grating lobes occur for the first time at double the frequency.

Patent DE-3805692-A1 (DE)
Title: Heat exchanger using oil as the heat dissipating medium
Inventor: KRAUSE HORST-HERBERT DR
IPC: F16N39/02
Filed: 1988-02-24
Abstract: In order to enhance the responsive behaviour and the cooling intensity of a heat exchanger, the oil-conducting channels are fitted with turbulence inserts, as a result of which the residence time of the oil inside the heat exchanger is lengthened and the transfer of heat to the cooling medium is increased. These turbulence inserts are, however, disadvantageous in the starting phase of the motor when the oil is still cold, since they promote the formation of "cold plugs" inside the heat exchanger and prevent the throughflow of oil. By completely or partially fitting the oil-conducting channels with turbulence elements made from materials which deform as a function of temperature (bimetal or memory alloy), the flow of oil is promoted in the cold state of the motor without having to dispense with a positive turbulence effect in the hot oil state, since the abovementioned turbulence elements project from their initial flat state due to heat and form the desired turbulence effect. The oil-conducting channels can be fitted completely or partially with turbulence elements of the abovementioned type in accordance with the ambient temperature of the heat exchanger. <IMAGE>

Title: Seat for motor vehicles, in particular passenger vehicles
Inventor: QUISTORF DIETER H DIPL ING
IPC: B60N2/06
Filed: 1988-03-07
Abstract: In the case of a seat for motor vehicles, in particular passenger vehicles, having a three-point support on the bottom section, all three support bearings lie on the side of the seat. They engage at one side on the vehicle tunnel and at the other side on the associated door sill. A three-point seat of this kind is distinguished in that it is affected to a lesser extent by vibrations of the floor pan, and the seat comfort and well-being of the vehicle passengers during the journey are hence substantially improved. Moreover, the mentioned features make it easier for passengers to get to the rear seats of the vehicle and ensure that the rear-seat passengers have more leg room. The seat under discussion can, moreover, be easily installed, and has a smooth-running adjustment mechanism and locking and release mechanism.
Patent DE-3814681-A1 (DE)
IPC: F04C9/00
Filed: 1988-04-30
Abstract: The device disclosed comprises a hollow cylinder connected to two pipe or hose connections. In known devices of this type, e.g. piston pump devices, air can enter the space behind the piston, which in many applications can result in incrustation formation due to contact with the medium to be dosed as well as in other undesirable side effects. To overcome these drawbacks, the hollow cylinder (1) of the new device is closed on one front face and has a sector-shaped rib (11) running from the cylinder wall to the centre of the cylinder. The height of the rib extends from the base to approximately the other end of the cylinder and a cylindrical component (12) is rigidly connected to the rib (11). A tightly sealing rotatable cover (22) with a sector-shaped rib (21) extending to the base (14) of the hollow cylinder is placed on the other end of the cylinder. The device is essentially an automatic suction, double-acting, closed dosing pump the interior of which is impenetrable to air.
