Patent DE-2839257-A1 (DE)
Title: Thin fabric transfer mechanism - has needles on a frame together with a plate for accurate positioning
Inventor: CRAWFORD DOUGLAS J
IPC: B65G59/02
Filed: 1978-09-09
Abstract: The equipment to handle and transfer thin fabrics from station to station, such as in garment making, has a frame with spaced needles on the under side, pointing downwards. A plate ranges under the frame horizontally. The plate is moved with the thin fabric, and is fitted with holes to accept the needles, which are also moved to pass through the material and the plate. There is a limit to determine the degree of needle penetration and a mechanism to hold the plate and the needles in a given position while the fabric is being moved from one station to another, and to detach the plate on arrival at the new station, and separate the plate from the frame. The needles are withdrawn from the fabric, so that the material is peeled off and laid in its new position. The design ensures accurate positioning of the fabric during transfer and during dwell times between working stations, without damage to the fabric by the positioning and holding needles.

Abstract: In this coin-operated gaming machine, for the purpose of reducing the number of mechanical or electromechanical constructional parts subject to wear, all the symbols of a playing field (16) which are assigned to an address memory are successively activated via electronic components by means of a microprocessor. At the same time, different sequence times can be preselected for each of the individual symbol sequences (11-15). A predetermined program generates random numbers for each symbol sequence (11-15), the individual symbols of each symbol sequence being activated intermittently. The symbol corresponding to the random number determined is successively stored in a microprocessor for the individual symbol sequences (11-15) and is held optically on the playing field (16). At the end of play, if a win combination is present, the win corresponding to this is added in the credit unit and the amount spent for playing the game is subtracted. Preferably, each symbol sequence (11-15) is represented on the playing field (16) by an annular series of luminous symbols, only one of which lights up at a time. As a result of the intermittent activation of the symbols of each symbol series, the lit-up symbol appears to rotate, different rotation times being preselectable for the various symbol sequences. <IMAGE>

Title: Electronic device for curing stable vices of horses - has remotely controlled impulse generator strapped to neck of horse
Inventor: SCHECKER ROLF
IPC: A01K13/00
Filed: 1979-09-28
Abstract: Stable vices of horses are difficult to cure and various restraints such as neck straps and tar oaint on surrounding woodwork are usually ineffective. The appts. aims at curing horses of bad habits without applying physical restraints. This is achieved by fitting two remotely controlled impulse generators to the neck of the horse. Two spring contacts transfer the electric shock produced by the generator to the neck muscles of the horse. When a remote high frequency transmitter is operated, the local receiver turns on a transistor which causes a capacitor to discharge through the primary of a step-up transformer. The secondary winding is connected to the electrodes. Amplitude and pulse repetition rate are adjusted so as to be effective without being injurious.
