Abstract: 983,846. Printed circuits. ROGERS CORPORATION. Sept. 29, 1961, No. 35186/61. Heading H1R. [Also in Division H2] A printed circuit assembly is produced by the steps of applying a thin conductive metal foil on a flexible synthetic fabric sheet of insulating material, placing the foil and flexible sheet assembly on a resilient base member, die stamping the foil to provide a circuit pattern on the insulating sheet without interrupting the continuous surface of the insulating sheet, and removing the unwanted foil from the insulating sheet. A thin dielectoic film or sheet 12 comprising a plastic sheet 16 including a synthetic fabric and having a coating 18 of phenolic resin on both faces has a conductive foil 15 die stamped on to the resin surface. During the stamping process the film 12 is placed on a resilient die base member 34 so that when the upper die member 24 cuts into the sheet of metal foil 15 secured on the surface of the sheet 12 the latter is depressed and is not turn during the cutting process, Fig. 5. After the stamping operation, film and conductive pattern are adhesively secured to a permanent rigid insulating base member of fibrous material impregnated with a curable resin. In another embodiment the film 12 and conductive metal foil may be placed directly on and secured to a permanent resilient insulating base member 34, Fig. 10, such that during the stamping process the film 12 bottoms in the depressions formed in the base member 34 and after moulding the resulting circuit 14 is formed flush with the surface. A plurality of dielectric films bearing conductive patterns may be taken from a roll, Fig. 11 (not shown) and mounted on a rigid insulating base to provide a multicircuit structure, Fig. 12 (not shown). Fig. 16 shows how the circuit patterns at different levels in a multicircuit unit may be interconnected. Six different circuit carrying sheets are superimposed on a base member 120 and typical connections are as shown at 170 where a portion 172 of the uppermost circuit is soldered at it edge to a portion 174 of an underlying circuit. Other underlying circuits may be interconnected by using apertures in the various circuit carrying sheets. For example circuit 176 is exposed by apertures 182, 183 in sheets 175, 184 and circuit 177 exposed by aperture 185 in sheet 186 with the result that a solder connection can be made between circuits 176 and 177. The conductors of two superimposed circuit carrying sheets, Figs. 13, 14 (not shown) may be connected to one another by rotor shorting elements of a rotary switch.

Abstract: 1,230,599. Biaxially stretching polyamide films. NIPPON RAYON K.K. 25 July, 1968 [25 July, 1967], No. 35590/68. Heading B5B. A process for drawing a substantially amorphous polyamide film comprises treating the film with water whereby from 1 to 6% of water by weight (based upon the weight of the film) is absorbed by the film, passing the film through a preheating zone, the temperature of the preheating zone and the period of residence of the film in the preheating zone being such that the water content in the surface layer of the film is substantially lower than the water content of the interior of the film and thereafter drawing the film simultaneously in the longitudinal and transverse direction at a temperature of at least 5‹ C. above the temperature of the preheated film and at least 30‹ C. below the melting point of the film. The film may consist of poly-#-caproamide, polyhexamethylene adipamide or sebacamide, poly-11-aminoundecanamide, polylaurinamide, or a polyamide copolymer. If the film consists of polyhexamethylene sebacamide the treating of the film with water may be effected in such a manner that the average water content of the film is 1 to 5% by weight. The film may be preheated to a temperature of from 60‹ to 30‹ C. below the melting point of the film. The film may be drawn at a speed of from 6000 to 100,000% per minute. The ratio of the longitudinal and transverse draw speeds may range from 2 : 1 to 0À5 : 1. The draw ratio at which the film is drawn simultaneously in the longitudinal and transverse directions may range from 16 : 1 to 4 : 1. The drawn film may be heat-set at a temperature not higher than 10‹ C. below the melting point of the film with the film maintained under tension such that its width remains constant. The temperature of the preheating zone and the period of residence of the film in this zone may be such as to provide a steep downward gradient in water content in a traverse from the interior of the film to its surface as shown by a curve obtained when the water content of successive layers of the film from the central layer to one or other of the surfaces of the film is plotted against the distance of the layer from the film surface. The expressions " draw speed ", "ratio of draw speeds " and " draw ratio " have the meanings specified in Specification 1,111,305.

Abstract: 1,220,892. Pulse radar. DECCA Ltd. 15 July, 1969 [25 July, 1968], No. 35617/68. Heading H4D. In a radar P.P.I. display system, means superimpose at least one marker line adjustable in position and direction and having a series of equally spaced marks along the line, means controlling the spacing of the marks is calibrated in terms of speed such that a craft would take a time t to travel between the positions represented by two adjacent marks and delay means gradually shifts the marks along the line such that each mark moves a distance equal to the spacing between marks in the time t. In the embodiment sawtooth generators 12, 13 each having a rate control input produce a marker line on a true-motion P.P.I., and each such input is fed with respective D.C. sine and cosine voltages from an adjustable potentiometer 15 energized by an adjustable potentiometer 16. The sawtooth voltages are fed via respective current generators to fixed orthogonal deflection coils 20, 21. The timebase produced is triggered to begin during an interscan period from a unit 23. To adjust the starting point of the trace D.C. voltages are produced in potentiometers 26, 27 which may be controlled by a rolling ball. The marker trace (which may be invisible) is modulated by brightening pulses from a fixed frequency oscillator 28 and a gate 29 provides for only a predetermined number of marker pulses each time the oscillator is operative; the gate is delayed relative to the start of the marker line by an adjustable pulse width delay circuit 30 (e.g. controlled by clockwork 31) to move the markers in the required manner. Switches 32, 33 enable a marker line to be displayed only when required; a circular marker is provided, controlled in position by potentiometers 26, 27 so that its position corresponds to the end of a line, when switches 32, 33 are closed. Several marker lines may be provided for. Fig. 2 shows the position of the radar-equipped craft at O, the position of a target at P, and respective marker dots such as 41, 42. If the new position, i.e. at a later time, of the target is at P<SP>1</SP>, and not coinciding with Q, the position to which the first marker dot has moved in the interval, potentiometer 15 is adjusted to bring the marker line through P<SP>1</SP> and potentiometer 16 is varied to bring Q and P<SP>1</SP> into coincidence; the direction of the true target track may then be read from a calibrated scale on potentiometer 15. Potentiometer 16 may carry a speed scale. After making similar settings corresponding to the markers for the radar-equipped craft, the display indicates future craft and target positions and the collision risk. Prediction of future position cannot be made if a craft is changing course, but the latter can be detected.

Abstract: 429,291. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Hathaway, J. L.; 711, 5th Avenue, New York, U.S.A.) Dec. 18, 1933, No. 35620. Convention date, Dec. 16, 1932. [Class 40 (v)] A multi-stage screen-grid pushpull amplifier is characterized by the use of reaction obtained by coupling the cathodes of the valves to the input circuit. As shown in Fig. 1, the two cathodes of the first push-pull stage V, V are connected to adjustable tappings on the input coil L1, which is centre-tapped to an earth-lead 16, the output coil L3 being similarly earthed through a centre-tapping 12 and the high-tension battery B. The pulsating screen-grid current through the condenser C3 assists regeneration, as well as variations in the anode current. The second stage VI, V1 is similarly arranged, except that the grid leaks R2 are in the grid circuit instead of in the cathode connection. In a modified arrangement a single " driver " feeds two push - pull stages in cascade. The valves of the last stage are directly heated through leads which form part of, or are threaded through the hollow coils of the input inductance L1, as shown in Fig. 3. According to the Specification as open to inspection under Sect. 91, the invention is applied to single-stage amplifiers. As shown in Fig. 1 (Cancelled) a coil L2, which is common both to the grid-cathode and anode-cathode circuits, and also to the screening-grid and cathode circuit, provides an inductive backcoupling through the coil L1, and also reacts on the control-grid directly through the voltage due to the anode or screen-grid current. The extent of reaction is controlled by a shunt resistance R1, whilst a grid-bias resistance R2 is shunted across a condenser C2. This subject-matter does not appear in the Specification as accepted.
