Title: Electropneumatic hammer with tool braking arrangement - formed by nitrile rubber sleeve acting on piston outside working zone
Inventor: BENEDIKT WILHELM DIPL ING
IPC: B25D17/24
Filed: 1979-07-19
Abstract: A clamping sleeve of an elastomeric material such as nitrile rubber grips the shaft of the tool or tool holder of an electropneumatic hammer, to prevent rebounding of the hammer piston. The elastic contact of the sleeve brakes the motion of the tool, and the sleeve has an end face which works with the end face of the piston, and acts as a direct or indirect stop for it. The tool is rotated by a carrier bush in which the profiled shaft slides and the bottom end of the clamping sleeve which is stretched on to the shaft works with an end face of the carrier bush also. The hammer has a more robust design and rebound hammering when the machine is at rest is prevented.

IPC: G02F1/133
Filed: 1980-03-05
Abstract: The display device using an integrated circuit, has a transparent outer layer (19) protecting an indicator layer (17) below which is an insulating layer (10) in which are embedded electrodes (51,50) spaced apart and insulated from each other. The indicator layer has its optical properties varied by altering the voltage across the electrodes, and is divided into zones. Behind these layers is the control circuit (11), remote from the indicator surface. An electric field is generated within this circuit, and applied to conductors (20,21) behind the insulating layer, to control the indicator layer. This field can be generated by a low frequency oscillation or a pulsating d.c. flow. A low frequency of between 1 and 10 Hz may be used, or a high frequency of 100 Hz or more. To prevent breakdown, further conductors (23) forming part of the printed circuit are included along another plane behind the plane of the other conductors.

Title: Roller bearing injection moulded as one piece - then rollers sheared from remainder and pushed axially onto pins
Inventor: ERTLE KARL ING GRAD
IPC: F16C33/52
Filed: 1980-04-28
Abstract: A method of making a roller bearing entirely from plastics is as follows. The individual rollers and the roller guide are injection moulded as a single component; when the injection mould is opened, the rollers are pushed axially (to the right), thus shearing off the connection between these rollers and the roller guide and the thin annular regions, so that the roller guide is entirely separate from the rollers. The rollers are then axially pushed onto the trunions intended for them, which form part of the roller guide. In particular (claimed) as a roller bearing for the wheels of a hand-pushed vehicle or cart. The entire assembly is made in one operation using one series of injection ducts.

Title: Velocity switching circuit for marine DC drive - selectively connects chemical energy cells in series or parallel configuration
Inventor: WAGENER PETER DIPL ING
IPC: H02P5/68
Filed: 1980-08-06
Abstract: The drive uses a DC shunt-wound motor supplied from a number of chemical energy cells. A velocity switching circuit controls the number of cells coupled to the armature of the motor and/or switches from series to parallel configuration or vice versa. The motor is over energised for a short interval to effect switching, with the armature disconnected from the energy cells at the current zero transition point. The configuration of the energy cells is adjusted and the excitation of the motor is altered to match the armature voltage to that of the energy cells before reconnecting the armature to the energy supply. Further velocity ranges are obtained by using partial motors mounted on a common shaft with armatures switched between series and parallel circuits.

Title: Wind-energy conversion plant - has controlled wind vanes mounted on rotation framework
Inventor: WUERTH GUSTAV DIPL KFM DR
IPC: F03D3/06
Filed: 1980-11-01
Abstract: The central part of the wind power plant is the stationary vertical post, around which is situated the rotation frame carrying the wind blades. The frame is rotatable, depending on wind direction, hydraulically, or electrically, and supports the shafts of the wind blades. The shafts are connected by a mechanical unit to the rotation frame in such a way, that the wind blades which are fixed to the shafts, always maintain the same angle to the frame work regardless of its position. The unit for maintaining this angle also rotates with the framework, depending on wind direction. The greater part of the wind energy is absorbed via the rotations of the framework and is fed directly to generators. The rotation frame can also be controlled against the wind by a wind vane.
