Title: Device for feeding individual sheets from a hopper to the platen of an office machine
Inventor: STEINHILBER HELMUT
IPC: B41J13/10
Filed: 1982-09-29
Abstract: In a device for feeding individual sheets from a hopper (14) to the platen (10) of an office machine, in which the drive energy of the device is provided by the platen, the energy requirement fluctuates during the separation and feeding operation. In order to reduce the peak values of this energy requirement, according to the invention an energy store is provided which can be recharged by means of the drive energy provided by the platen (10) and discharges the stored energy to the device during the phases of the separation and feeding operation with the maximum energy requirement. A cam disc (28) is preferably provided, on whose circumference a follower lever (34) rests under the stress of a tension spring (38). The tension spring (38) is stressed by a rising cam part (30) while the stored energy is discharged again as drive energy to the cam disc (28) via a steeply dropping cam part (32). <IMAGE>

Title: Electronic recording, storage and reproduction device for displaying road maps and the like on CRT or plasma screens, e.g. in motor vehicles
IPC: G09B29/10
Filed: 1982-09-29
Abstract: The invention relates to the conversion of standard town plans and other road maps for reproduction in selectable sections on a CRT or plasma screen, primarily in motor vehicles. It includes the required combination of electrical engineering/electronic components for recording, storage and reproduction of the original (road map or the like). Since the recording and reproduction involve static image contents, no expensive equipment of the type used in commercial image data processing is required for the information conversion. The image contents may, for example, be stored on low-cost audio cassettes and can be transferred to the screen for example by means of modified audio cassette players or car radio/cassette players with the intermediate connection of an electronic conversion device.

Patent DE-3245518-A1 (DE)
Title: Drive arrangement for motor vehicles, in particular for a tractor
Inventor: BRAUN FRITZ DIPL ING
IPC: B60W30/18
Filed: 1982-12-09
Abstract: In order, in a motor vehicle with a hydrostatic transmission having a hydrostatic axial piston pump, to permit operation similar to that of a motor vehicle with conventional automatic transmission, a direction selector lever for determining the swivelling direction of the rocker of the axial piston pump, a foot lever fitted with a return spring on the left of the steering column of the vehicle for returning the rocker and finally a hand lever for limiting the absolute value of the rocker angle of inclination are provided. The transmission propels the vehicle forwards when the direction selector lever is swivelled forwards and the same applies analogously to reverse travel. If the hand lever is swivelled forwards, the inclination of the rocker and hence the speed of travel increases.
Patent DE-3246600-A1 (DE)
Title: Price sign for motor vehicles
IPC: G09F7/02
Filed: 1982-12-16
Abstract: A price sign, which is preferably to be used for labelling used vehicles, has below a holding device a detachable additional sign, on which appropriate details about the vehicle can be listed. Since this additional sign is exchangeable, the price sign can be used repeatedly for other vehicles. The numbers forming the price can also be exchangeable, which increases the possibilities of re-use of the price sign and adaptation to different vehicles. In this case, a closed loop, which can, however, be opened by bending it out of the plane of the sign, results in a stable suspension which can securely bear the entire sign with additional signs, for example on the rear-view mirror of a vehicle.

Title: Device and method for controlling the charging of alumina in a molten-salt electrolysis cell
Inventor: HEINZMANN ULRICH
IPC: C25C3/14
Filed: 1983-02-16
Abstract: The alumina is charged in a controlled manner using known means such as alumina feed pipes, daily storage hoppers, metering devices and/or downcomer pipes, in conjunction with a chisel (30) which can be moved up and down and which keeps at least one crust perforation open. Superimposed on the production current is an alternating current circuit which enables the chisel (30) to be raised immediately by means of an electronic process control system (36) if the chisel enters the electrolyte (14). The alternating current circuit comprises an alternating current source (32), an electronic relay (34) and two capacitors (40). If the alternating current circuit is not closed within a specified time after the chisel (30) has been lowered, the electronic process control system (36) triggers an increase in the pneumatic or hydraulic pressure on the chisel (30). <IMAGE>
Patent DE-3305347-A1 (DE)
Title: Vehicle headlamp
Inventor: ROEHLING WILHELM
IPC: F21V7/00
Filed: 1983-02-17
Abstract: The invention relates to an elliptical reflector for a vehicle headlamp which is constructed in accordance with the projection principle. In order to achieve a widely spread light distribution, the eccentricity of the reflector increases from the vertical axial longitudinal section to the horizontal axial longitudinal section, the inner focal points of each axial longitudinal section being congruent, in common with the associated vertices of the elliptical sections produced in this case. In one or more subregions, however, the reflector has a reflection surface that is rotationally ellipsoidal. The light emitted from this region ensures as large as possible a light intensity in the optical axis of the headlamp, and thus on the centre of the roadway.
Patent DE-3308451-A1 (DE)
Title: Vertical trough guide in circulating carriers for documents and other items
Inventor: RAMSAUER GEORG
IPC: B65G1/127
Filed: 1983-03-10
Abstract: To provide oscillation-proof trough guidance in circulating carriers of documents and other items, steering levers with track rollers which run in guideways (all-round guides) are used. Steering levers, which are inclined (approximately 45 DEG ), have hitherto mostly been used either on one side or, for better protection, on both sides in designs. Designs are also known which use a vertically arranged steering lever with a track roller respectively above and below the centre of rotation. A double guide path in the arcs of the circle is, however, required for a design of this sort. Line crossings necessitate openings or distributors which can give rise to malfunctions. To achieve a simple, safe solution the design submitted for patent is chosen, which uses a vertically downward pointing steering lever for oscillation protection, on whose lower end a sufficiently long horizontally arranged sliding lever is mounted near the track roller. The length of the sliding lever only has to cover a short section of the path in the region of the apexes (at the tops and bottoms of the arcs) when the track roller in this region is outside the guideway. Not so much during normal passage, but only when the cabinet is approached can the trough be twisted due to centrifugal force, with simultaneous loading on one side and a great deal of play in the guideway, in such a way that ...

Title: Method and device for thinning out
Inventor: EGGERT JENS
IPC: A01G23/093
Filed: 1984-04-06
Abstract: A method and device for thinning out wooded areas. The invention proceeds from the fact that the device is equipped both with a cable winch and with a chopping device which are both motor-driven. The essential steps of the method are in this case: the thinning-out device first draws itself under its own cable force towards the tree to be removed; the chopping device is subsequently set in operation and cuts up the tree starting at the trunk base and continuing to the crown. The possibility is afforded that bringing the device close to the tree also takes place by means of the telescopic arm of a tractor instead of by means of the cable winch.

Title: Direct DC converter with automatic field attenuation
Inventor: SARTOR GERHARD
IPC: H02P7/281
Filed: 1984-07-21
Abstract: This direct DC converter circuit serves to feed a direct current series-characteristic motor (8) of an electric vehicle, in particular short-distance vehicle, from a contact line system (3), automatic field attenuation being provided in travel mode and controlled field attenuation being provided in braking mode. In order to permit contactless changing between driving and braking operating mode, two electronic switches which can be activated and deactivated separately are present, one switch being connected as a travel valve (10) in series with the armature winding (7) of the motor and being switched periodically in travel mode and the other switch being connected as a brake valve (19) in series with the field winding (18) of the motor and being switched periodically in braking mode. In travel mode, a freewheeling field current is formed over two freewheeling field diodes (16, 17) and a composite resistor (15) when the travel valve (10) is conductive. When the travel valve (10) is blocked, a freewheeling armature current flows across a freewheeling armature diode (20) and the field winding (18). In braking mode, a field current which flows across the armature winding (7) is produced when the brake valve (19) is conductive whilst the freewheeling field current designated above is formed when the brake valve (19) is blocked. Optionally, pure mains feedback, mixed mains/resistor feed and pure resistor feed are possible, for which purpose a braking resistor (14) can be switched into the load circuit via a resistor brake valve (21). <IMAGE>
