Filed: 1983-11-08
Abstract: The invention relates to a secrecy switching device for initiating a switching process after successive operation of a plurality of previously defined push-buttons in a keypad of any design and size, and signalling in the event of operation of an <<incorrect>> push button. The circuit arrangement according to the invention consists of an input circuit having a window discriminator and two gates arranged downstream, and one or more state memories connected thereto. The voltage potential at the input to the one gate is below the threshold voltage of that gate, and the voltage potential at the input of the other gate is above the threshold voltage of that gate. The input of the window discriminator is connected to the make contacts of the push buttons. The outputs of the state memories are fed back to the mating contacts of the previously defined push buttons in order to initiate the switching process. The state changes of the state memories are used to initiate the switching process in a known manner. The signalling in the event of operation of an <<incorrect>> push button takes place by means of an output pulse from the gate which is not connected to the state memories. <IMAGE>

Title: Adjustable venturi carburettor
Inventor: YAMAMOTO TADAHIRO
IPC: F02M9/127
Filed: 1984-01-05
Abstract: An adjustable venturi carburettor comprises an additional intake air passage, an additional adjustable venturi section and a non-adjustable nozzle section in addition to an intake air main passage, an adjustable venturi main section and an adjustable nozzle section. When the amount of intake air is small, as in the case of idling operation of the internal combustion engine, the intake air passes mainly through the additional, adjustable venturi section in order to produce a vacuum which is sufficiently large to convey fuel through the non-adjustable nozzle section into the additional intake passage. When the amount of intake air is large as in the case when the internal combustion engine is operated at high load, the intake air passes mainly through the adjustable venturi main section. Since two venturi sections are formed, it is possible to increase the amount of fuel introduced into the intake passage constantly over a wide operating range of the internal combustion engine.

Patent DE-3415619-A1 (DE)
Title: Telescopic control handle
Inventor: FUKUDA KINSYO
IPC: B60N2/90
Filed: 1984-04-26
Abstract: A telescopic control handle for a lifting mechanism for a seat of a motor vehicle is disclosed, which mechanism has a helical spring which moves the shaft of the control handle into a through-bore of a holding housing in a sliding fashion and as a result moves it into a position of rest in which the shaft is pulled back into the holding housing; for the purpose of actuation, the shaft assumes a front position in which it protrudes from the holding housing; by virtue of its elasticity, the spring continuously acts on the shaft so as to move it into its position of rest. At least one radially outwardly pointing projection is formed on the shaft and at least one recess which receives the projection in a sliding fashion is provided in the through-bore of the holding housing. In this way, the restoring spring for pulling back the shaft of the handle by means of free and unimpeded rotation of the shaft can not be twisted and deformed in that the shaft is prevented from turning freely; in addition, the engagement section of the spring is thus prevented from disengaging with its attachment elements or being broken off.

Patent DE-3430871-A1 (DE)
Title: Mechanical belt-tightening device for safety belts
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/46
Filed: 1984-08-22
Abstract: The invention relates to a mechanical belt-tightening device for safety belts, which in an accident exploits the energy of the rotating cardan shaft or a corresponding drive shaft for tightening back of the belt above a predetermined deceleration, especially in the direction of travel. A coupling disc which is mounted concentrically relative to the cardan shaft, but without coming into contact with it, is carried along with the cardan shaft by means of positive locking and winds up a traction cable. This traction cable is connected to a conventional clamping roller coupling on the rolling up device, where the winding shaft is twisted in the belt retracting direction. Use of the latter device together with anti-locking braking systems, which prevent zero rotation of the wheels (and therefore of the cardan shaft) in any panic braking before an accident, guarantees the operational reliability of the device. <IMAGE>

Title: Piezo-drive having contact-pressure force deflection and oscillation-system guidance
Inventor: FURCHERT HANS-JUERGEN DR
IPC: H02N2/04
Filed: 1985-03-29
Abstract: The invention relates to a piezo-drive having contact-pressure force deflection and oscillation-system guidance, which can advantageously be used for positioning purposes in apparatus and automation technology since, using it, very small movement paths and good dynamics for small masses down to a few hundred grammes can be achieved. The essence of the invention is that an object-carrier part is guided on wear-resistant surfaces of piezo-oscillation contact-pressure systems and is moved in one coordinate when the piezo strips are suitably electrically energised. The object-carrier part is mechanical or optically connected to a measure embodiment or to an image-clarity analyser, such that the location signals produced via a position controller connected thereto allow the electrical energising of the piezo-strips to be controlled in accordance with the existing movement task. The position which is reached is secured by the existing friction without any drive effect, even under the influence of small opposing forces. <IMAGE>

Title: Hammer drill
Inventor: WANNER KARL DR ING
IPC: B25D11/06
Filed: 1985-03-29
Abstract: A hammer drill with a motor-driven air-cushion percussion mechanism is proposed in which a reciprocating striker delivers its energy to a tool guided in the hammer drill and/or to its holder and changes over into an idling position if the tool and/or its holder deflects due to a lack of working resistance in the percussion direction. To improve the idling behaviour, at least two intermediate anvils (34, 36) are arranged between the striker (27) and the member (tool 18 and/or its holder 6) absorbing the percussion energy of the striker (27). Subsequent striking when changing over from the working position into the idling position is thereby prevented. <IMAGE>
