Patent DE-2635797-A1 (DE)
Title: Copying engraving machine with rotating table - has stepped pulley drive to provide different speeds of tool rotating about workpiece
Inventor: KIRSCHBAUM HEINRICH
IPC: B23Q35/10
Filed: 1976-08-09
Abstract: The copying engraving machine has a rotating table mounted on a slide which runs on guide bars. The rotating table is driven by a shaft which carries a stepped pulley. A belt passes around one of the grooves in the pulley and each end of the belt passes around a small pulley on a spindle fixed of the slide. The ends of the belt are fixed to the frame which supports the guide bars. This arangement of the belt causes the pulley to rotate as the slide moves on the guide bars. The pulley in turn drives the table so that the engraving tool describes a circle on the workpiece.

Title: Mechanically displaceable shaping body for textile workpieces - has extending thrust rod but overlapping segments to form closed surface even when fully extended
Inventor: MASSECK KLAUS
IPC: D06F59/02
Filed: 1976-10-22
Abstract: The mechanically displaceable moulding body for textile materials as in the production of peaked caps etc. contains at least one central thrust rod (13) which is mounted in the upward axial direction (27) wherein its axis remains fixed during any thrust movement whilst the rod (17) itself has translatory displacement along the axial direction. This to and fro movement of the rod (17) spreads out its attached leverage system (9 to 16) at right angles from the axis and back again, whereby spatially rounded pressing segments (1 to 8) attached to the ends of some of the levers are moved by same outwards and inwards in the same direction of movement. The first direction of movement forms the pressing direction against the adjoining inner surfaces of the cap to be processed with this mobility being defined by at least one stop.
Patent DE-2657754-A1 (DE)
Title: Air sifting appts. for separation of particulate material - uses strong air current displacing different particles to hoppers according to weight and size
Inventor: REIFF HERBERT
IPC: B07B4/02
Filed: 1976-12-20
Abstract: The air sifting plant is for separating material of various particle sizes and weights. It operates by feeding the material to be sorted at high speed through a strong gas current. This speeds up the movement of the different sized particles across the original direction of movement so that the materials are moved further away from the original direction of movement, the smaller their weight and size. The materials of different weight, with a similar flight path can be separated from each other by a vibrating sieve since there is a variation in particle size.

During transport and/or storage, the ring (1) is accommodated in the socket (4) of the pipe (6) in a position nearer the inner end of the socket than its position (7) for initial mounting, and from which it is rolled into the sealing position in the socket on assembly. The ring can be accommodated for transport and storage at the innermost end (2) of the socket, being held there by self-clamping action, or a radial recess can be provided at this point, for it.
Patent DE-2712338-A1 (DE)
Title: Particle separation from air stream - by rotating cone and twin annular slot (SW 25.4.77)
Inventor: APELSKOG ULF
IPC: B01D45/14
Filed: 1977-03-21
Abstract: Small particles are separated from an air flow by admitting the dust laden air at the top centre of a tank and by diverting it upwards by a revolving cone, parallel to an inner cone on the inlet pipe. A ring, fixed to the top of the tank near the wide end of the revolving cone forms an outer slot for the particles, which are collected in the conical bottom of the tank, and an inner slot for the clean air which is discharged through a pipe. Filter screens for the same purpose must be very fine and clog rapidly. The resulting downtimes and labour requirements are saved with the new design.

Title: Non-contact coin dia. determination device - employs two light bands interrupted and re-established by coin during natural movement
Inventor: WICHODIL KARLHEINZ
IPC: G07D5/00
Filed: 1977-06-02
Abstract: The dia. of a coin inserted into a ticket, vending or gaming machine is determined. The two bands of light which are interrupted by the coin originate from two light sources and strike two photoelectronic sensors. The output signals of the sensors set flipflops after being differentiated and pulse shaped. In the time between interruption of the first light band and interruption of the second light band a fixed oscillator frequency clocks a first counter. In the time between interruption and reestablishment of the first light band it clocks a second counter. The final state of the second counter is multiplied by a correction factor and is constantly compared with the instantaneous state of the first counter. If the compared quantities are equal a flip flop is set whose output gives an "accept" signal.

Title: Electronic alarm switching system - has multiple detectors scanned to cause flashing of station indicating number
Inventor: TESCH KLAUS
IPC: G09G3/14
Filed: 1977-07-14
Abstract: An alarm system for industrial processes allows the warning condition of a number of detectors to be indicated on a numerical segment display. Detector outputs are coupled over an interface that can trigger an interface to cause a thyristor stage to activate an alarm. At the same time a counter is continuously cycled by a clock generator and the output compared with the input interface status. A binary converter provides an output to cause activation of the display. Since the counter is continuously cycled the display flashes.

Title: Control method for stochastic processes - comparing each realised element with nominal value and correcting process when limit difference is reached
Inventor: MEHLER ULRICH
IPC: G05B13/02
Filed: 1977-08-30
Abstract: The stochastic processes are of Markov's chains type and controlled by following a known distribution function. After each sequential test process each realised element is continuously compared with a nominal value, and the difference between values above and below the nominal value is produced. The process is corrected when this difference reaches a specified limit. The correction size is derived from the number of elements realised up to the reaching of the limit value.
