1. Bolt and counterpiece, which can be connected by axial plugging together and subsequent radial turning with each other, the bolt (1) having toothing (5) on its jacket surface and the counterpiece (2) having countertoothing (11), which can be engaged with the toothing (5), in a recess (21) receiving the bolt (1), and the bolt (1) on its jacket surface and the recess on its inside surface having ...

For the recycling of electrical batteries, in particular of a mixture of high-power batteries for equipment of any chemical composition, and also of assembled printed circuit boards and electronic components, a pyrolysis of the unsorted mixture is carried out at a temperature between 450 DEG and 650 DEG , then an electrolysis of the pyrolysis slag is carried out and subsequently a separation of t...

The invention relates to a power supply circuit for an X-ray tube for converting direct current to high-frequency pulses and including at least two transistors (8, 9) whose collector-emitter circuits are controlled by means of a pulse-width modulator (5) through base control transformers (12) in a manner that transistors (8, 9) operate in push-pull fashion, one terminal (+) of a direct-current sou...

A spring compressor for large coil springs especially for motor vehicle axle springs comprises first and second disc-like pressure plates which are located at spaced locations along the axis of a cylindrical guide tube and each has a central bore opening. A threaded spindle has a spindle head with a key profile and it is rotatably mounted in an axial thrust bearing of the cylindrical guide tube. T...

The glove is predominantly leather with an inner surface which is plastic coated. The upper and lower parts of the fingers (excluding the thumb) are reinforced and have a plastic coating. The sides are of leather.

The circumference of the hose prior to insertion is made shorter than that which it is in the rest position. and also shorter than the pipe internal circumference. Between its two layers of elastic material are fitted two or more strips or wires of e.g. steel, in screw-line form and transversely. - The screw-lines have, in relation to the strip thickness, a suitable distance between each other, an...

Arrangement for heating and/or cooling elements consisting of an elongate support member 1 which supports pipes 13 which convey heating medium and/or cooling medium and which, by means of attachments 5, are arranged in heat-conducting contact with the support member, each attachment 5 consisting of two parts, a holder part 10 which fixes the pipe 13 and a connection part 14, and the two parts 10, ...

Two reception parts (5,6) working together as a pair, each handle its own radiation lobe or group of lobes. Photodetectors (5,6) within the two reception parts form part of an electrical signal initiation circuit (6,5,B). The circuit, dependent upon the reception by the receiving parts of radiation lobes, produces in time separately occurring electrical signals (P1,P2) corresp. to the different in...

In an arrangement for transmitting an optical pulse sequence 15, use is made of a laser diode 2 and a control circuit 3 connected thereto. Instead of using homogeneous pulses in the optical pulse sequence 15, a pulse train with two or more part pulses is used for each pulse. These part pulses are brought about by a laser diode 2 being activated and deactivated a number of times during the pulse ti...

Pulse transmission and reception are monitored, with the transmitter being connected to a register in which the transmitted pulses are represented during distance determn., and the receiver is connected to a second register for pulse reception. The second register receives and stores simultaneously all the pulses reflected from those in the first register. To both registers is connected a calculat...

The appts. incorporates target followers, distance measurement components and primary circuits which produce guide signals dependent upon the target following and distance measurements. A release signal is produced when a release distance is present between missile and target. Secondary circuits, using information from the target measurement an angle between the missile and target speed vectors. U...

The missile has a zone tube by which is detects a target at a predetermined distance, towards which it is flying.
