Title: Spark type metal polishing process - period of rectified pulses is limited by a discharge circuit
IPC: B23H3/02
Filed: 1974-04-16
Abstract: Metal removal rate is increased by raising the energy level and increasing the time delay between impulses, using mains supply frequency. The workpiece (2) is submerged in an aqueous electrolyte (3) which is slightly conductive and which is pumped (5) through a gap (6, 7) between the workpiece and electrode (1). Conduction across the gap (7) is through a mains transformer (8), a thyristor (9) and a rectifier bridge (10) which rectifies a small part of the transformer secondary current. The electrode is negative polarity. Rectified impulses are passed through a diode (11) to the thyristor trigger via a circuit (13) which limits its period of excitation.

Title: Locking joint for microscope support - has electromagnet acting on stack of spring washers to release or tighten friction grip to allow movement of coupling
Inventor: COEYTAUX GEORGES
IPC: F16M11/06
Filed: 1980-10-15
Abstract: The mechanism is used for a surgical microscope and controlled by an electromagnet to block rotation of the microscope about a vertical axis when it is in use. The movable arm (2) which is mounted on the vertical axis is gripped by a stack of curved washers (1). The curved spring washers normally provide enough friction to prevent rotation. An electromagnet (7) to one side of the axle is arranged to release the pressure which normally maintains the coupling in the locked state. The armature (7a) of the electromagnet is arranged to move vertically and is attached to a horizontal lever (8) pivoted (9) on top of a bracket (6) which is attached to the axle. When the electromagnet is energised, the lever acts on a peg (4) and stop (3) above the stack of spring washers in order to release them, and allow movement of the coupling.

Title: Method for simultaneously controlling and programming a plurality of transponders and device for implementing this method
IPC: G06K17/00
Filed: 1997-12-04
Abstract: The method involves using an external transmitter to transmit energy (1) to a group of read and write transponders. After a time delay (TRR) the transponders emit identification signals (2-3,4-5) through allocated time windows. An external receiver receives the signals during the first window and determines if there is dispersion. If there is dispersion the supply of transmitted energy is interrupted quickly enough to deactivate all the transponders. Energy transmission is resumed and if no transponder signal dispersion is now detected, a window of reception is used to send groups of data to the transponders which are simultaneously programmed into their memories.

Title: Process for producing raisins-marc brandy and filter store
Inventor: CSASZAR ANTAL
IPC: C12F3/08
Filed: 2001-02-08
Abstract: The fermented spent raisin containing liquid is distilled and purified to produce an alcoholic drink. At the start of the distillation process the product contains more oil and other contaminants, so it is discharged from the separator chamber. The discharged liquor is visually inspected and the discharge is stopped when it appears to be clear. It is expected that 2-3 litres of contaminated liquor will be discharged. As the process is continued, oil is retained in separator chamber. At the end of the distillation process the contents of the separator chamber are discharged. The contaminated liquid is routed to a closed waste-water treatment pit. Equipment is proposed comprising the following: A filter cabinet is provided with filter elements such that the inlet side of the filter cabinet is formed into a separator chamber. This chamber is provided with discharge pipe, complete with a stop valve and observation chamber. The volume of the separator chamber is 30-35% of the total volume of the filter cabinet. The separator chamber and the rest of the filter cabinet are separated by a wall which is provided with a transfer pipe having a discharge below the liquid level of the filter compartment. The transfer pipe is located 5-15mm below the top of the wall. The discharge of the separator chamber is normally connected to a waste-water treatment pit.
