Title: Rapid updating of invalid card number lists in transaction terminals - using central radio transmitter to send invalidated identification codes simultaneously to all terminals in network
IPC: G07F7/08
Filed: 1990-06-11
Abstract: An increasing number of financial transactions are made using plastic cards and automatic transaction terminals (e.g.  cash dispensers). To guard against unauthorised use of cards, terminals often have to request information from a central data bank. This process is slow and costly. If terminals are fitted with pre-tuned radio receivers,  information on invalidated card numbers can be broadcast simultaneously to all terminals from a central point. Terminals can also be equipped with radio transmitters to forward the information or to signal attempts at unauthorised card use. ADVANTAGE - Increased security against unauthorised transactions. Reduced validation delays during transactions.

Title: Call and feed voltage supply for PBX telephone appts. -  feeds DC potential in rest and call states to subscriber line pair via different paths, under microprocessor control
Inventor: NIJMOLEN GERRIT WILLEM
IPC: H04M19/02
Filed: 1990-08-29
Abstract: The PBX is microprocessor controlled, and the telephone appts has a series connection of a bell and a capacitor in rest and call states.

In the rest and call states, the potential of the feed DC voltage (U) is applied to one speech core (a) via a current source (SQ) and via a first current sink (SS1) the earth potential is linked to the other core (b). In the cell state, alos second current sink (SS2) is so controlled by the microprocessor (M) call pulses so that it disconnects the current source in the call pulse cycle. It connects the second core to the feed potential via an electronic switch (5), and the first core to the earth potential. ADVANTAGE - No need for relays and chokes for call signal disconnection.

Title: Rotary-type IC engine - incorporates combustion chamber in which fuel burns continuously
IPC: F01C1/344
Filed: 1990-09-11
Abstract: The rotor body (2) is rotatably located, displaced axially to the engine housing, and is provided with segments which are U-shaped and enclosed by sprung, wear-resistant U-shaped piston rings. Sealing of the segments in channels (5) is supported by pressure channels (10). In the chamber of the smallest volume between the segments, basic body (2) and housing (3) a flow channel is located in the air movement direction which allows compressed air from one or two adjoining compressors to flow into the combustion chamber. In the combustion chamber is an injection nozzle feeding fuel continuously, and which is so affected by the compressed air that a gas-air mixt. is produced, with combustion occurring in the expansion area, causing the engine system to be driven. USE/ADVANTAGE - For Otto or diesel engines, to convert combustion energy into rotary movement directly, to optimise compression of gas-air mixt. with combustion of the mixt. over a longer period, permitting better use of energy.

Title: Warp knitting needle - has function wire which clear lint in both directions to clean needle groove
Inventor: BOBE ANETTE DR ING
IPC: D04B35/06
Filed: 1991-03-22
Abstract: Cpd. needle wires are made from spring wire. Two arms are made, one forward to the needle point, and one to the rear. Arms are present to an angle, so that pressure is required to insert them into the groove of the needle. During assembly, the two arms of the control wire are pressed into the groove of the needle, so that they lie flat against the bottom of the groove. Arms are therefore at a spring tension, when the casting in which they are set, is fixed into position on the machine. Point of the rear arm is set at a sharper angle to the bend than the front point. Bend in the casting may be replaced by two adjacent straight parts, anchored into the casting by end formations on the separate wires. During knitting, the pointed end may leave the needle groove, but the arm is still supported in it. USE/ADVANTAGES -For warp knitting machine. Clearing of lint accumulation takes place in both directions, ensuring a clean groove.
