Patent DE-3327543-A1 (DE)
Title: Conical ring/double stud/steel tube support
Inventor: STRAHL GERHARD
IPC: E04G25/04
Filed: 1983-07-30
Abstract: A telescopic support which consists of two steel tubes which can be displaced in one another and can be extended. It is used for supporting structural parts, trench walls, and general supporting purposes. Steel studs in the form of internal wedges are welded in an opposite double row on the upper tube. The lower tube of the support is constructed at one tube end to form a tapered tube connecting piece, which is approximately 50 mm long and through which the upper tube can slide with only a small amount of play. A simple-spiral conical ring is stamped out of the upper edge of the tube connecting piece, milled, which conical ring has in each case one penetrating slot for the steel studs on the upper tube at its lowest point and at the central level of the conical ring, which studs can engage by means of their internal wedge-shaped construction around the upper edge of the conical ring, can be adjusted in height on the ring, and can be wedged firmly. This novel support can be extended and fixed in the operating position in a few seconds, and hence considerably faster than conventional supports. This support has no more moving parts, has no thread lock, and no holes in the upper tube, which in consequence retains its full mode capability. It is produced from only commercially available tubes and profile parts and has no forged parts.

Title: Method for the manufacture of a solid cage for a ball bearing
Inventor: ELGES HELMUT
IPC: F16C33/38
Filed: 1983-09-06
Abstract: A solid cage for a ball bearing comprising two races (1 and 2) which can be axially joined together is to be manufactured in such a way that the ball pockets, in which the balls (5) are mounted, have a perfect surface quality and do not exhibit any misalignment in the area of the parting line (7) between the two races (1 and 2). This is achieved in that the two races (1 and 2) are initially joined together with an accurate fit, then fixed in relation to one another and in the fixed state are provided both with axial bores for fixing rivets, and bores running radially into which the ball pockets for the balls (5) are then milled by means of a cherry. Since the two races (1 and 2) are machined complete in their joined state, no division defects of any kind occur. The surface quality of the ball pockets is on the whole very uniform, since a cherry is used, the axis of rotation of which is radial to the two races (1 and 2). <IMAGE>

Title: Electronic circuit arrangement for converting the duration of a pulse into a proportional voltage
Inventor: DREYER ADOLF DIPL ING
IPC: H03K9/08
Filed: 1983-10-19
Abstract: An electronic circuit arrangement is proposed for converting the duration of a pulse into a proportional voltage which is used for conditioning information contained in the duration of the pulses in a suitable manner such that the information can be supplied to an analog/digital converter and from there to a microcomputer. For this purpose, the output current of a voltage-controlled power source is integrated in an integrator over the duration of the pulse and, after receiving the information, the integrator is initialised by the microcomputer. Controlling the power source during the integration allows the control function of the power source to superimpose the integration result. <IMAGE>

Title: Mast collar
Inventor: RAFELD KARL
IPC: B63B35/79
Filed: 1984-03-02
Abstract: The invention relates to a mast collar as a connecting element between mast and wishbone boom of a rig for a surfboard, with a locking device which holds the mast collar, designed as a body at least partly surrounding the mast surface in an annular manner, in place on the mast. To avoid the need for special tools to secure the mast collar to the mast surface, to ensure that the mast collar is secured only at quite particular, specially designed locations and to substantially facilitate operation when the mast collar and thus the wishbone boom are being secured to the mast, it is proposed that the locking device consist of a wedge body which juts out beyond the top and bottom ends of the collar and is arranged in a longitudinally movable manner in a groove formed on the inside of the collar, extending approximately in the longitudinal direction of the mast and opening towards the surface of the mast, and that the collar can be moved into and out of clamping contact with the mast surface by displacing the wedge body in the groove.

Patent DE-3419741-A1 (DE)
Title: High-pressure piston pump
Inventor: WIMMER OTTO
IPC: F04B1/04
Filed: 1984-05-26
Abstract: The invention relates to a high-pressure piston pump, preferably having a plurality of pump units, each piston being driven by a drive member, and hydraulic pressure medium being drawn in by each piston and being conveyed to the high-pressure consumption point. The object of the invention is to reduce considerably the surface forces and frictional forces arising between the elements of the pump, in order to make it possible to use the pump on units having extremely high operating pressures (up to 700 bar) while employing acceptable motive forces. This object is achieved, according to the invention, in that between the drive member and the piston an intermediate member is interposed, which is made of a material having very good antifriction properties and which has concave indentations on both sides, the indentation formed on one side being engaged by the convex-shaped end of the piston and the indentation situated on the other side being engaged by the convex-shaped peripheral part of the drive member. <IMAGE>
Patent DE-3419779-A1 (DE)
Title: Method and circuit arrangement for controlling the access of subscriber stations to a data transmission channel of a data transmission system
Inventor: SCHEINERT STEFAN DIPL ING
IPC: H04L12/413
Filed: 1984-05-26
Abstract: In data transmission systems with local control, subscriber stations can access the data transmission channel independently of one another. Each subscriber station wishing to access the data transmission channel checks, for example by means of a message identification circuit, whether the data transmission channel is free or not. The probability of access collisions occurring increases if there are a multiplicity of subscriber stations within the data transmission system. To avoid access collisions of this type, subscriber stations seeking access transmit an access signal with a specific priority at the end of the message and, during the transmission of the access signal, check whether a higher-priority access signal is being transmitted via the data transmission channel. The subscriber station with the highest priority transmits the message, while lower-priority subscriber stations wait for the end of this message before instigating further access to the data transmission channel.
