A torque converter (11) with a lockup clutch (11a) is interposed between an engine (2) and a driven wheel, and the lockup clutch (11a) is coupled or uncoupled on the basis of a pre-determined lockup characteristic. When a slip value of the driven wheel against a road surface reaches a given value or higher, torque to be applied to the driven wheel is decreased to thereby perform slip control. Duri...

A control device for an automobile has at least one sensor (8) for detecting an operational state of the automobile. An output from the sensor is applied to a sample and hold circuit (11) which is adapted to provide a time displaced output to a hierarchical group of neural elements (13). The neural elements operate upon said time displaced signals by varying the weighting of the signals and/or thr...

A clutch is provided for transmitting power of an engine to either of the front or rear wheels of a motor vehicle. A brake switch is provided to be closed by depressing a brake pedal of the vehicle to produce a brake pedal, and a detector is provided for detecting operation of an anti-skid brake system and for producing an anti-skid signal. In response to the brake signal and to the anti-skid sign...

The infrared detector is composed of a projector which produces a double-modulated infrared pulse beam by modulating a modulated beam of a high frequency with a low frequency and a light receiver which receives the double-modulated infrared pulse beam. The projector (1) comprises a divide-by-N frequency dividing circuit (12) which divides by N the frequency of basic-frequency signals having a basi...

A method of structurally modifying a silica monomode optical fibre (4) by launching optical power into the fibre (4) from a Nd:YAG laser operating at 1.064um and raising the temperature of a portion of the fibre (4) by bringing a metal film (12) into contact with a polished half-coupler block (6) to absorb energy from the laser (2). A structural modification of the fibre is initiated which propaga...

The appts. incorporates several curved body pairs which are arranged in pairs, move in different directions and are equipped with spiral friction linings. Devices are provided for adjusting the friction force and fibre length in addition to yarn clamps. The unit features segment pairs (10,11) on both sides of the joining zone (1) as a friction surface. Each segment pair consists of two opposite in...

The at least one suction roller (5) is mounted in the paper-conveyor and driven by drive mechanisms (7) so that it is moved to-and-fro by a guide (6) to the machine operating rhythm. The suction roller has suction openings (5a) extending across the sheet widthwise across the direction of travel. At the start of the forward movement, the suction roller is placed against the front sheet in the stack...

A device for cleaning large quantities (3) of water from debris at overflow edges (2) has a separating surface (10) which is arranged in a stationary position and through which the quantity of water flows. The separating surface (10) is designed as a piece of a cylinder circumference (7) with an axis (8) lying parallel to the overflow edge (2). Allocated to the separating surface (10) is a receivi...

In apparatus for the cross-cutting of continuously fed material with the sheets that have been cut being briefly deflected by revolving braking elements 10 - said braking elements extending across the width of the signatures - and thus being decelerated, a first drive 3 drives cyclically operating, systems (roller 11 with deflection cams and cutting cylinder 13) said systems 11, 13 being operated ...

A process is for washing laundry through driving the washing solution guided in a circulation system through the washing at pressure. The pressure is produced by centrifugal force. The washing machine for operating the process is equipped with a container (8) for the washing. In the container (8), the washing is supplied with washing solution under pressure directed at a wall, which is equipped wi...

A washing machine is operable to perform at least two spinning cycles and a loosening cycle which is disposed therebetween and consists of a detaching phase for detaching of laundry from the inward wall of its drum and of a distribution phase, during which the drum is alternately stopped and driven at a predetermined rotational speed lower than the rotational speed of laying-on. The detaching phas...

The invention relates to a knife with interchangeable blades (M), having a housing (1) and a slide (4) which is guided longitudinally displaceably in the housing (1) and can be fixed at predetermined spacings of a catch (6) formed on the housing (1), and on which the blade (M) is interchangeably held by means of a pin (18, 19) engaging into a hole of the blade (M). To be able to use such a knife w...

To create a locked pipe connection, a locking device (5) bears upon an add-on ring (4) placed on a relief at the end (1) of one (A) of the elements to be joined. Half of the meridian section of at least a portion of this ring's external surface is in the shape of an L, the concavity of the L facing radially inwards. Application to automatic connections for cast-iron pipe systems.
