Title: Motor-operated hedge clippers
Inventor: ADE ERICH ING GRAD
IPC: A01G3/053
Filed: 1988-05-13
Abstract: In known hedge clippers, the excursion travels of two actuating members are utilised both for actuating the switch and for actuating a coupling arranged between the hedge clipper drive and the double eccentric which sets the clipper cutters in motion in the opposite direction. The coupling arrangements known for this purpose are relatively expensive and have to be made with maximum precision if the period of time from actuation of the coulping to standstill of the clipper cutters is to be as small as possible. The invention is to make it possible to achieve, with a minimum of outlay, an extraordinarily rapid standstill of the clipper cutters after triggering of the uncoupling process. The eccentric-side part of the coupling is designed as a driver plate (29, 29') which has a hollow hub (29'') which is provided with driver elements (30), to which counter-driver elements (32) mounted on a projection (31') of the double eccentric (31) correspond. The driver disc (29, 29') arranged turnably on an axle bolt (24) mounted firmly in the housing (34) can be brought into engagement with the drive-side part of the coupling by coupling elements (25, 25') influenced by the sliding member (20, 20'). <IMAGE>

Patent DE-3819882-A1 (DE)
Inventor: WAEBER RENE
IPC: D01G99/00
Filed: 1988-06-10
Abstract: The invention relates to a method of reducing the stickiness or tackiness of cotton flocks. For this purpose, cotton flocks delivered by any suitable conveyor mechanism are received in a flock chute and brought, by rolls or rollers, as a fiber batt between a number of heated rolls or rollers, in order to be heated such that the stickiness or tackiness of the honeydew on the cotton is thus reduced to an extend which no longer has an adverse effect on subsequent machinery. Downstream of the heated rolls or rollers the fiber batt is again opened into cotton flocks by an opening roll or roller and fed to a pneumatic conveyor line through which the cotton flocks are fed to the subsequent machine.

Title: Apparatus for securing a shoe on a bicycle pedal and bicycle pedal having such an apparatus
Inventor: ROMANO ANTONIO
IPC: B62M3/08
Filed: 1988-08-24
Abstract: The tread body of a bicycle pedal bears a plate which is connected to the tread body, in a manner pivotable about a vertical axis, at its front part relative to the direction of travel of the bicycle. A spring loads the plate in the direction of a closed position in which, together with the tread body of the pedal, it bounds a seat for receiving and locking an engagement element fastened on the sole of the shoe of the cyclist. By twisting the shoe about the said vertical axis, the plate can be moved into the opened position. When the opened position is reached, the plate is locked in this position by means of a locking element, so that the engagement element can be released from the seat in a longitudinally directed backward movement. By introducing the engagement element into the seat in an opposite direction of movement, the locking element can be automatically released.

Title: Device for decentralised data processing, and method of loading programs for it
Inventor: SEKIZAWA TOSHIHIKO
IPC: G06F9/445
Filed: 1989-01-27
Abstract: In a decentralised data processing system, in which a number of processors (101 to 108) are connected via a network, and in which programs can be exchanged among the processors, each of the processors monitors the state of its own programs, and the load on the other processors, as it is shown by a message (1) on the network, and according to its assessment outputs a message (2), which gives its own state, or contains a program with a content which is shown by a code in a received message. The processor which receives the message transmits a program which is held in it according to the program content code, corresponding to the load on the processors, etc., and the assessment of the content of the received message.

Title: Metal-encapsulated, gas-blast power circuit breaker (power switch) having connecting devices for the interrupter unit
Inventor: MEINHERZ MANFRED
IPC: H01H9/08
Filed: 1989-02-10
Abstract: In the case of a metal-encapsulated, gas-blast power circuit breaker (40) having a gas-filled housing (41) and an interrupter unit (42) which is supported in an insulated manner in the housing, it is intended to reduce the time penalty for removal of the interrupter unit (42) from the housing (41). Arranged between the interrupter unit (42) and at least one of the fixed-position connecting conductors (52) is an isolating contact device (51) whose operating direction runs essentially at right angles to the longitudinal axis (L) of the interrupter unit (42). A guide track with a protective bracket (48) results in it being possible for the interrupter unit (42) to carry out an axial movement for removal from the housing after interruption of the separation (isolation) of a casing piece (65) and a mating contact piece (66) (isolating contact device). The power circuit breaker described is particularly suitable for use in metal-encapsulated, gas-insulated, high-voltage switching installations. <IMAGE>

Abstract: A changeover switching device for a telephone device for the connection of two telephone stations (FE1, FE2) to a common telephone line (La, Lb). The changeover switching device has one bistable relay for each telephone station in whose two switching states a setting device (SV1, SV2) or a resetting device (RV1, RV2) is in each case activated. Make relay contacts (k2.1', k1.1') are in each case disposed in the legs (La1, La2) of the telephone line leading to the telephone stations when the setting circuits of a different telephone station are activated. The changeover switching device has a priority circuit (VR) which can be activated and de-activated, is connected to the resetting device (RV2) of the second telephone station (FE2) and generates a reset signal when the hook switch contact (GU1) of the first telephone station is closed, while the setting device (SV2) of the second telephone station is activated. When the setting device (SV2) of the second telephone station is activated, the priority switch (VR) is initially switched to a standby mode in which it is supplied with feed voltages and a blocking signal is applied to it along a conductor path routed via the a-connection (a1), the hook switch contact (GU1) and the w-connection (w1) of the first telephone station (FE1). <IMAGE>

Title: Locking device for a roof-hatch cover interlock
Inventor: STUEWE GUENTER
IPC: E05B63/18
Filed: 1989-03-17
Abstract: In the case of known roof hatch covers which are arranged on battle tank turrets, it is possible for the interlocking mechanism to be displaced while a roof hatch cover is open. In consequence, damage can occur, especially to the cover seal. In order to avoid such damage, the invention provides a locking device (8) on the roof hatch cover (1), which lock device (8) automatically prevents displacement of the interlock slide (3) from the "open" position to the "closed" position in the open roof hatch position. The locking device (8) is of simple and robust construction and consists of a piston/cylinder unit whose locking piston (9) always assumes a locked position (13) with respect to an interlock slide (3), under the force of a compression spring (45) in the open roof hatch position. This locking device (8) does not require any major modifications in order to install it on already existing assemblies of the roof hatch cover (1). Roof hatch covers (1) of battle tank turrets (2) which are already in service can therefore be retrofitted in a simple manner. <IMAGE>

IPC: A22C11/00
Filed: 1990-05-10
Abstract: In order to do away with the artificial skin, which has to be peeled off again, in the production of smoked sausages and to obtain sausages with a smooth surface, the sausage meat is put in tubular sleeves which are subsequently heated for long enough until the sausage meat has completely coagulated and the sausage has completed its maturing and reddening process. The sausages are then taken out of the tubular sleeves for smoking. Smoking can be performed with the sausages still warm: then, however, the sausages are vacuum-packed immediately after smoking. In another variant, the sausages are cooled in the tubular sleeves and smoked when cold.
