Title: Arrangement for compensating direction finding errors of a  twin path cathode ray tube direction finder
IPC: G01S3/14
Filed: 1971-08-04
Abstract: 1344547 Radio direction finders LICENTIA PATENT-VERWALTUNGS-GmbH 4 Aug 1971 [7 Aug 1970] 36661/71 Heading H4D In a twin path cathode ray tube direction finder amplitude or phase compensation for environmental influences on the antennae is provided in the paths which compensation is automatically adjusted as a function of the operating frequency. In a ship-mounted direction finder (DF) the effects of the superstructure are compensated by adjusting the relative gain of the loop channels 2, 3 by amplifiers 5 or attenuators 19 and in the sensing aerial channel by phase shifter 4. Since the directional and phase errors can be predetermined for particular operating conditions and frequencies the compensation is arranged to be automatic. Crossbar unit 16 receives binary coded inputs 14-16 from a frequency counter or an electronic frequency controller representing the operating frequency and band from which it produces sixty control signals 12 depending on the operating conditions. The signals 12 are received by two further cross-bar units 10, 11 which provide output signals 18 for the loop channels 2, 3 and signals 24 which are binary coded at 8 to drive phase shifter 4. The loop channel compensation provides for up to 34 degrees of error either in eighteen equal steps of 2 degrees or in 1 degree steps at lower errors and 3 degrees steps at higher errors. The phase compensator 4 provides 0-360 degrees of compensation in equal steps for 15 degrees from five elements combined in series as dictated by the coded signals 6. The cross-bar unit 13 may utilize soldered or plugged interconnections or may use photo-diodes or transistors and a light source illuminating the unit through a punched card, the card being programmed for particular operating conditions, e.g. loading of the ship.

Title: Process and apparatus for manufacturing single or multi-layer mats containing fibres and fluid
IPC: B28B1/52
Filed: 1974-08-22
Abstract: 1475747 Platens felting G SIEMPELKAMP & CO 22 Aug 1974 [22 Sept 1973 (2)] 36901/74 Heading D1R [Also in Division B5] Fibre sheets are made by subjecting single or multilayer mats containing fibres and fluid, e.g. wet asbestos cement mats, to compression between platens by (i) applying a pressure pulse to cause felting, and then (ii) applying a consolidation pressure to effect hardening by means of the upper platen, expressed fluid being led away before and/or during compression. The pressure pulse generates a pressure higher than the consolidation pressure and produces a shock-wave which reorients the fibres. If the mat is placed on the lower platen with the interposition of a perforated screen, a needling effect may be simulated. The pressure pulse may be produced by causing the upper platen 3 to fall freely on the mat or by the release of a pressure medium from a vessel to act on said platen; as shown, the upper platen 3 and tup 7 are driven by a piston and cylinder 8 which is actuated by a feeder 16 connected to an accumulator 15 to permit free fall. A return device 9 is provided. The pressure pulse may be so adjusted as to produce a dust layer on the surface of the compressed mat and so minimise tackiness. Moisture may be led away before and during the pulse. The compression pressure is preferably built up immediately after the pulse, if necessary before the collapse thereof. The mat may be held by vacuum on a moving screen 13 which is driven over the lower platen 2. As shown in Fig. 2, this platen is provided with a coarse web 10, a fabric 11 and a fine sieve 12. The screen 13 may be replaced by a filter cloth. The platens 2, 3 may be corrugated for producing shaped sheets.

Title: Remote electronic multiple control system
Inventor: ROBIN CLAUDE
IPC: A63H19/24
Filed: 1968-08-05
Abstract: 1,242,453. Electric selective signalling. C. ROBIN. 5 Aug., 1968 [8 Aug., 1967], No. 37194/68. Heading G4H. [Also in Divisions H3-H5] In a system of signalling over an A.C. mains supply to control one or more utilization devices on a. movable body a single frequency A.C. signal is superimposed on the A.C. mains to actuate a receiver which is responsive to the relationship between the signal and the instantaneous phase of the A.C. supply to determine the selected control function. Fig. 1 shows a basic version of the system in which power is supplied to a motor 16 from an alternating supply on lines 11 and 12 which are fed from terminals 5 via a transmitter 10 which superimposes high frequency signal currents on the supply. The signal currents are detected by a circuit including the capacitor 13 and transformer primary 14a which together resonate at the signal frequency, and the resulting voltage developed across the transformer secondary 14b causes transistor 15 to conduct to pass current through motor 16. Further actuators 17 and 17a are provided in the arms of the rectifier bridge feeding the motor 16 and transistor 15 and the current through these actuators may be differentially varied, whilst maintaining the current through motor 16 constant, by differentially varying the proportion of the positive and negative half cycles of the supply during which the high frequency signal is applied to the lines. Alternative forms of the receiver are described which include a reaction winding between the transistor collector and the motor, Fig. 2 (not shown), or an addition signal amplifier feeding the transistor 15, Fig. 4 (not shown), and incorporating rectification of the signal voltage for control, Figs. 5 and 6 (not shown). Also described is a circuit using a "Symistor" (Registered Trade Mark) which performs the function of both the feed bridge rectifiers and the control transistor 15.
