Patent DE-3739992-A1 (DE)
Inventor: TAMURA YASUYUKI
IPC: B41J35/16
Filed: 1987-11-25
Abstract: A thermal transfer material is provided by disposing a first ink layer having a yellow color and a second ink layer of another color on a support. In transfer recording, the second layer alone or both the first and second ink layers are imagewise transferred depending on the time the material and a recording medium are in contact, onto the recording medium such as plain paper. If the second ink layer is blue or silver, the combination of the first and second ink layers provides a transferred image in green or gold. When the thermal transfer material is used in combination with another similar transfer material, a multi-color transfer recording in three or four colors is effectively accomplished.

Patent DE-3803666-A1 (DE)
Inventor: BOEDER DIETER DIPL ING
IPC: F42B23/24
Filed: 1988-02-06
Abstract: The invention concerns a device for ensuring self-righting and correct positioning of bomb-type objects such as anti-tank mines. It has been found that when exposed to impact due to the detonation of nearly mines or to the firing of guns in the vicinity of a mine, the latter may be overturned due to the elasticity of its self-righting device. In a self-righting device (10) for a bomb-type object (12), the wire frame (24) which serves to right said object is reinforced by a strut (34) so that said object remains securely positioned even when exposed to detonation. The strut (34) associated with each wire frame (24) is hinged by a first hinge joint (32) to the bomb-type object (12) and by a second hinge joint (42) to a sliding clip (36) which slides longitudinally on the wire frame (24). When the wire frame (24) swings away completely from the bomb-type object (12), the sliding clip (36) of each wire frame (24) is locked in position, thereby preventing the wire frame (24) from swinging back.

Title: Device for selecting objects via a display on a cash register which can be operated by electronic or mechanical push-button selection
IPC: G07G1/12
Filed: 1988-04-22
Abstract: Device for selecting objects or the like via a display (3) on a cash register which can be operated by electronic or mechanical push-button selection by a customer. Illumination (14) and a control button (3) are allocated to each object which can be selected. Actuation of the button (3) causes the order which has been activated by the customer to be displayed on the operator's side in the number-of-items space (9) and in the article space (10). When the customer has actuated the "order total" key (6), the automatic locking mechanism (11) on the operator's side is disengaged, allowing sales personnel access to the money compartment.   A second option is also available in addition, which permits customers to pay the total sum themselves using cards or cash. This makes embezzlement by sales personnel impossible. <IMAGE>

Patent DE-3816105-A1 (DE)
Inventor: BOECKER ALBERT
IPC: E06C7/12
Filed: 1988-05-11
Abstract: The invention relates to an inclined lift comprising several telescopic elements, the individual telescopic elements consisting of guide rails which are connected like a ladder and are guided on one another. The essential feature of the invention consists in the fact that, in addition to the guide rails guided on one another, a further guide rail is arranged in particular in the top area of the inclined lift, i.e. on the last telescopic guide rail. The further guide rail is arranged as a narrow track between the external guide rails of the last (top) telescopic element and is guided in a sliding manner on the latter. The load-lifting member (slide) is provided with additional roller equipment for guidance on the narrow track. The narrow track forms a so-called integrated ridge bend piece on which the slide is positively guided in the ridge area and on the opposite side of the roof. <IMAGE>

Title: Unit for increasing the charge pressure on supercharged internal combustion engines in the partial load and lower engine speed range
Inventor: WIMMER JOHANN
IPC: F02B37/20
Filed: 1988-05-28
Abstract: In order to extend the effective range of use of an exhaust turbine on an internal combustion engine, the supercharger is combined with a bypass system. By dividing and reheating the bypass flow, it is possible on the one hand to keep the temperature level upstream of the turbine high and on the other to achieve a higher rate of flow, so as to maintain the high efficiency of the supercharger even at partial load and slower engine speeds. As a result, depending on the design embodiment, improvements can be obtained in consumption, in torque, in load adjustment and in the exhaust emission.

IPC: B22D41/50
Filed: 1988-06-23
Abstract: The intention is to improve a casting device for metal melts with a pouring nozzle (30), in particular a pouring spout and nozzle, and a deflector (40) which is arranged downstream of the latter and, with the pouring nozzle (30), defines a flow gap (38). To this end, the deflector is designed as a baffle (40) with a surface (41) that slopes relative to the axis of the pouring nozzle (30) and the said surface defines, with a zone of the internal surface of the pouring nozzle, the flow gap (38). In addition, the baffle (40) is to be displaceable relative to the pouring nozzle (30), along the axis (M) of the latter. A flow model which serves to determine operating conditions at pouring nozzles has a bulge (15) with a surface (16) that matches the metal-specific solidus line. <IMAGE>

Title: Differential with a multi-plate clutch as a lock-up clutch
Inventor: GAZYAKAN UENAL
IPC: F16H48/30
Filed: 1988-09-01
Abstract: A differential case (1) drives two output gears (6, 7) via at least one differential gear (5) on a differential pin (4). The differential case (1) is supported via two taper-roller bearings (9) in an axle case (10). The differential case (1) forms an outer-plate carrier and an output gear (6) forms an inner-plate carrier. With the outer plates (13) and the inner plates (14), the plate carriers form the multi-plate clutch (16) as the lock-up clutch of the differential. Pressurised fluid in an actuating chamber (19) between a stationary part (17) and a working part (18) of a locking cylinder (20) presses a plate assembly (15) of the multi-plate clutch (16), via the working part (18), a thrust bearing (25) and a pressure ring (24), against an end face (39) of the differential case (1) axially in front of the differential pin (4), pulls on a retaining ring (28) on a bearing neck (29) of the differential case (1) via the differential case (1) and, via a back-up ring (27) and a counterbearing (26), exerts a reaction on the stationary part (17) of the lock cylinder (20). Return springs (23) between the thrust ring (24) and the differential case (1) press the working part (18) against the stationary part (17) via the thrust ring (24) and the thrust bearing (25) and open the multi-plate clutch (16) completely. <IMAGE>
