Patent DE-2924636-A1 (DE)
Inventor: FISCHER HERMANN
IPC: B41F21/10
Filed: 1979-06-19
Abstract: By means of an optical scanning device, automatic control of the axial displacement of a sheet gripper device is undertaken, said sheet gripper device being fastened on leaf spring-like supports on a back-pressure cylinder, transfer unit or pre-gripper. By means of two photosensitive elements (73, 75), the side edge of a printed sheet (77) is scanned with reference to a fixed reference line (71) and from this scanning a correction signal is produced which is processed in a servo-control circuit (65). Via an adjusting motor (59), the servo-control circuit (65) controls the axial displacement of the sheet gripper device in the desired direction and by the desired amount, thus resulting in precise alignment of a fed-in printed sheet (77). <IMAGE>

Title: High resolution weighing system - has inductive distance sensor and facilitates digital display and reduction in numbers of mechanical parts
Inventor: MAHR JOACHIM
IPC: G01G7/02
Filed: 1979-08-22
Abstract: A high resolution balance with an electronic digital display and an inductive distance sensor with associated drive and evaluation circuits is esp. for letter and parcel weighing but is also suitable for personal and domestic weighing machines. The sensor operates without contact and can be fitted without difficulty in any existing balance. For balances designed to incorporate it, large economies can be made in mechanical components. The electrical loading on the inductive distance sensor is so low that nonlinearities normally associated with coil heating are negligible over long period of operation. Linearity, resolution, and temp. stability far exceed the requirements of the systems involved. Mfr. and adjustment of balances based on the sensor are simplified compared to conventional balances. They are suitable for large scale production.

Inventor: PEREGO AMBROGIO
IPC: B23P11/02
Filed: 1979-08-27
Abstract: To improve known draw-off devices in which only a radial expansion of the part to be forced off is effected, it is proposed to create a draw-off device in which, together with a radial expansion of the part to be forced off, an axial component acting on it at the same time permits reliable forcing-off, which is achieved by a pressure piston (10) being arranged in an axially displaceable manner in a guide cylinder (9) provided with a fastening device (6), the guide cylinder (9) being provided with a mechanically operable pressure sleeve (12). Furthermore, the fastening device (6) can be screwed in a sealing manner into the part (2) to be released, in such a way that a pressure pocket (16) is formed between the pressure piston (10) and the shaft (1). By the arrangement of an abutment (14) in the guide cylinder (9), the draw-off device according to the invention can also be used, by means of the pressure piston (10), as a mechanical device without the use of a pressure medium. <IMAGE>

Title: Change dispenser for vending machine - has mechanical interlock to control transfer of coins through return mechanism
Inventor: GRUENIG DIETER
IPC: G07F11/18
Filed: 1979-04-21
Abstract: A vending machine avoids damage to the coin return mechanism due to undue force in operation. In a cigarette packet dispenser several containers have a common interlock bar linked to a coin-actuated mechanism. Coins are entered through a slot and pass through a coin checking stage. The coins build up in a transfer passage formed between two plates. A number of interlock latches are tripped by the number of coins entered. The bottom coin in the series operates a lever to release the operating mechanism. When the slide drawer is released the coins are transmitted into the magazine.
