Title: Coaxial connector has metal rings in outer conductors - to compensate inner-conductor connectors inductance and to retain dielectric rings
Inventor: FRITSCHE HANS-ADOLF
IPC: H01R13/646
Filed: 1974-04-18
Abstract: The coaxial cables connector has the two outer conductors meeting end on and separated from the two inner conductors by dielectric rings to prevent short circuiting. The inner surfaces of the ends of the outer conductors have steps to accept two conducting rings. The rings have lips that hold the dielectric rings in place and act as capacitive compensation for the unwanted inductance caused by the connector assembly of the inner conductors. The halves of the connector are held together by an external collar which screws across both of them. The connector can be used to join together different types of standard connector terminals.

Title: Brick prodn. from clay with addition of petroleum coke fines - to decrease heat conductivity and increase strength
Inventor: MORANT MAX
IPC: C04B38/06
Filed: 1974-04-29
Abstract: Bricks are produced by mixing together clay (opt. with additives) and 1-3 wt. % (pref. 1.5-2 wt.%) of petroleum coke, moulding the mixt, e.g. by extrusion under press. and firing. The petroleum coke is pref. calcined. Peat coke or soot can be used instead of petroleum coke, being practically free of sulphur and fluorine. During the firing of the bricks, coke burns out thus increasing the porosity of the product. This results in a decrease of heat conductivity (up to about 10%). The strength of the prod. is increased. These advantages are due to the purity of petroleum coke, esp. when calcined (absence of S, F and other harmful impurities). Fines obtd. by coking of petroleum fractions for metallurgical purposes can be utilised.

Title: Snow grip clamps for pneumatic tyre - with cross piece and clamping jaws tensioned by central threaded spindle
Inventor: STRELLI ALBERT
IPC: B60C27/04
Filed: 1975-04-23

Title: Flat heater for household appliances - has wire lengths kept short by using two coplanar windings
Inventor: KRATOCHVIL HARALD
IPC: H05B3/16
Filed: 1975-06-18
Abstract: The flat heater, for household appliances like toasters, consists of an insulating plate with a row of central holes to allow the wires to be wound around it to give two coplanar flat heating surfaces. The advantage of the central row of holes lies in making the heating wires short, i.e. instead of one wire wound around the plate, two are used with correspondingly shorter lengths of wire. The wires are held in position both in the central holes and at the edges by steps and cutout sections. The finished heater is also rigid.

Title: Conductive layer attachment for printed circuit card - uses set of slots and resilient pressure tool in stamping system
Inventor: BAERTL RICHARD
IPC: H05K3/04
Filed: 1975-08-13
Abstract: A method of attaching conducting circuitry to cards uses a sticking and stamping technique together with patterns of suitably shaped slots in the cards. The method is suitable for automatic production of circuit boards, and is more rapid than existing printing and etching techniques. Basically, the card (1) has a number of shaped slots (3) cut in it, which define where the edges of the conductors are to be produced. The slots have one sharp and one rouned edge. A metallic layer (2) is then stuck to the card (1) over the slots, using an unspecified adhesive, and a rubber or plastics member then presses the layer into the slots, fracturing it along the sharp slot edge. This produces the conducting pattern required.

Title: Phase comparator circuit for television frame synchronisation - has controlled oscillator loop driven from mains supply
Inventor: FROEHLICH WALTER
IPC: H03L7/08
Filed: 1975-08-13
Abstract: The phase comparator circuit is used to synchronise the television frame frequency with the mains supply frequency. A rectifier connected across the secondary of a mains transformer (TR) supplies a DC feed to a stabiliser units (SF). The unit has three stable output voltages, two of which (U2, U3) are symmetrical about the third (U1). This third output is connected via a resistor (R1) to the AC side of the rectifier and two clipping diodes (D1, D2) are connected to the other two outputs. The resulting waveform is trapezoidal. The waveform is integrated (IN) and connected to a scan unit (AT) whose second input is driven from a frequency divider (FT) which, in turn, is driven from a frequency-controlled oscillator (OS). The oscillator frequency is therefore locked to the mains supply frequency and the divider output signal is the scan and deflection pulse for the equipment.
