Title: Hinged covers for openings in motor-vehicle bodies or the like
Inventor: HOELZER EBERHARD
IPC: E05D11/10
Filed: 1981-05-08
Abstract: The invention relates to hinged covers for openings in motor-vehicle bodies, which, for example, contain the tank filler neck. The previous hinge and spring devices for hinged covers of this type are not only complex in terms of parts but also require a relatively large amount of installation space and height, so that appropriately large and deep openings in the body are required. In order to simplify the hinge and spring devices for these hinged covers and to construct them flatter, the invention proposes to provide hinge parts (11), fastened to the hinged cover (10), with at least two intersecting surfaces (14; 43) of which at least one forms a stop surface which fixes the closing position of the hinged cover (10) under the influence of at least one resilient part (33) on the hinge plate (31). The resilient part (33) of the hinge plate (31) furthermore fixes, in cooperation with the hinge parts (11) of the hinged cover (10), the opened position of said cover too by holding the hinged cover (10) against a stop (35) on the hinge plate (31). By virtue of this combination of the hinge arrangement together with a spring device, a parts-saving, low construction is possible and, as a result, the openings in the body can be kept correspondingly flatter. Passenger cars constitute the main area of application of the invention. <IMAGE>

Title: Control circuit for a printer
Inventor: MERTGEN MANFRED DIPL ING
IPC: G06K15/00
Filed: 1981-07-27
Abstract: If characters are to be printed by a printer, the control characters and data characters required for this are transferred from a central processing unit (ZE) to the control circuit of the printer. The control circuit contains a microprocessor (MP) which decodes the control characters coming from the central processing unit (ZE) and controls their execution. When the microprocessor (MP) determines that a data transmission command is present, it starts a sequencer control (DMA) which carries out the data transmission from the central processing unit (ZE) to a memory (MM). For this purpose, the sequencer control (DMA) accepts the data characters, initiates their recoding with the aid of a recoding table and stores the recoded characters in a page memory which is contained in the memory (MM). The recoded characters are than used for activating a character generator. The sequencer control consists of a sequencer, a microprogram memory and registers in which the data characters, the recoded characters and the addresses for the recoding table and the page memory are contained. By using the sequencer control (DMA), a very high data transmission rate from the central processing unit (ZE) to the page memory in the memory (MM) can be achieved. <IMAGE>

Title: Process and apparatus for producing and filling containers from thermoformable and sealable or weldable film webs of plastics material
Inventor: MILDNER EBERHARD
IPC: B29C49/00
Filed: 1981-10-16
Abstract: The invention relates to the producing and filling of containers with liquid free-flowing or solid products. For this purpose, the film webs are heated to plastication temperature between their upper and lower outer zones and fed to a moulding and sealing station. In the latter, the film webs are brought into contact and sealed to each other, with the exception of the regions in which the containers and filling channels in connection with them are thermoformed. During the sealing operation, moulding tubes enter into the filling channels to be formed and introduce a pressure medium or create pressure equalisation when a negative pressure is applied to the station. Subsequently, the containers are filled via the filling channels, which are subsequently closed. <IMAGE>

Title: Arrangement for controlling the air-fuel ratio of an internal combustion engine
Inventor: SUZUKI HITOSHI
IPC: F02D41/14
Filed: 1981-10-27
Abstract: An arrangement for controlling the air-fuel ratio of an internal combustion engine has an emission control system with a three-way catalytic converter for controlling the air-fuel ratio as a function of the operation of the engine. A transitional state sensor detects the opening state of the throttle valve of the engine following an idling sequence. A feedback control loop sets the air-fuel ratio to the stoichiometric ratio. Control circuits are actuated by the output signal of the transitional state sensor for a predetermined period in order to increase the amplification of the feedback control loop, thereby rapidly adjusting the air-fuel ratio to the stoichiometric ratio in the transitional state. <IMAGE>
Patent DE-3142713-A1 (DE)
Title: Method for controlling stepped transmissions in motor vehicles
Inventor: ESCHRICH GERHARD
IPC: B60W30/18
Filed: 1981-10-28
Abstract: A method is proposed for controlling a stepped transmission connected downstream of a drive motor in motor vehicles with pressure-controlled friction elements, in which transmission parts have to be accelerated during a shifting sequence and in which the transmission input speed is simultaneously reduced, preferably by influencing of the moment delivered by the drive motor. At the same time the fall in the moment on the transmission output which occurs due to the speed gradient in conjunction with the inert mass of the transmission parts to be accelerated is compensated for. The compensation is produced by increasing the pressure in the friction elements whilst influencing of the drive motor takes effect or by reducing the pressure at the end of the shift sequence. <IMAGE>

Title: Cylindrical rotor for choppers
Inventor: KOLB LOTHAR
IPC: B27L11/00
Filed: 1982-01-20
Abstract: The invention relates to a cylindrical rotor for choppers for crushing wood waste or wood-like plant components to form chopped shreds. Choppers with cylindrical rotor generally have a chopping rotor with the shred outlet in front of the chopping blade, viewed in the direction of rotation. The invention achieves the object by means of a cylindrical rotor for choppers with output of shreds in the cutting direction behind the chopping blade through channels which continuously widen approximately in a wedge shape from the shred inlet to the shred outlet and which are divided off transversely with respect to the rotor axis by a plurality of plates or "sheet metal rosettes" arranged in the cross-sectional plane. The latter plates which divide off the abovementioned channels are to have at the shred inlet right inside the blade cutter a cutter which runs perpendicular with respect to the latter and is made of wear-resistant cutting material. On the other hand, on the shred outlet these plates which divide off the channels are to taper off, continuing the rotor circumference, as far as the shred inlet of the following blade. In front of each chopper blade in the direction of rotation and parallel to the blade, an interchangeable wear strip is to be arranged at the shred inlet in front of the gap in the channels provided for this purpose.

Title: Brake disc for disc brakes, in particular for motor vehicles
Inventor: NAEUMANN EMIL
IPC: F16D65/10
Filed: 1982-03-30
Abstract: In the case of a brake disc for disc brakes, in particular of motor vehicles, with a pot-shaped disc hub which is formed integrally on one disc side and forms a brake drum which accommodates the brake shoes of an internal shoe brake designed, in particular, as a parking brake, the brake shoes are assigned a stop, preferably in the form of a radial annular shoulder formed integrally on the periphery of the drum. This annular shoulder is provided at a short distance from that longitudinal side of the brake shoe which faces the disc hub base. If braking operations are carried out exclusively with the parking brake, the disc hub expands conically in the direction of its front wall under the action of the frictional heat which arises, for which reason the brake shoes have a tendency to drift in the direction of the disc-hub front wall. They are prevented from moving to a damaging extent in this way by the fact that they run up against the stop.
