Title: Improvements in or relating to secondary radar systems
IPC: H01Q21/29
Filed: 1955-02-18
Abstract: 811,496. Aerials; radar. LEVELL, D. A. Feb. 13, 1956 [Feb. 18, 1955; April 26, 1955], Nos. 4963/55 and 11967/55. Drawings to Specification. Class 40 (7). The invention relates to a secondary radar system of the type in which side-lobes of the main directional interrogating radiation pattern are prevented from actuating a co-operating responder because of disablement of the latter by conditioning pulses radiated prior to the interrogating pulses at a field strength in all significant directions intermediate that due to the main and side lobes of the directional aerial pattern. According to the invention such a system comprises a horizontally extending directional aerial and a second aerial comprising two or more components located on opposite sides of the directional aerial. Successively occurring conditioning pulses are applied to the two components of the second aerial respectively prior to radiation of an interrogating pulse from the directional aerial. In one embodiment the directional aerial comprise twenty-four vertical metal plates #/4 high and 0.6 A apart. These plates all lie in a common vertical plane and are arranged in pairs in housings having metal bottoms and backs, triangular metal ends and radiation transmissive fronts. A gap is left in the centre of the directional aerial and the second aerial components arranged in front of and behind the gap, facing outwardly in each case. These aerial components may comprise single plates similar to, and mounted in housings of the same type as, those of the directional aerial. In use, groups of four pulses may be radiated from the system, a reference pulse transmitted over the directional aerial, then, after a delay of (6) 6 Á seconds, a conditioning pulse radiated by the forward looking second aerial component closely followed by a similar pulse radiated by the other second aerial component, and finally the interrogating pulse 16 Á seconds after the reference pulse and also transmitted by the directional aerial. The operation of the co-operating responder is described with reference to Figs. 3 and 4 (not shown) and is similar to that described with respect to Fig. 6 of Specification 734,588.

Title: Insulating substrate with metallic coating and method for manufacturing same
IPC: H05K3/14
Filed: 1976-02-10
Abstract: 1493088 Ion plating SUMITOMO BAKELITE CO Ltd and T TAKAGI 10 Feb 1976 [12 Feb 1975 (2) 26 Feb 1975 (2) 5 March 1975 6 March 1975 25 March 1975 28 March 1975] 05090/76 Heading C7F An insulating film, sheet or plate is coated with metal by "cluster ion plating". In this method, the metal 12 is heated in crucible 7 to form vapour which leaves as a jet through a hole in the top of the crucible. On emerging from the crucible, the jet expands and forms a cluster which is ionized by collision with electrons generated by applying D.C. between ionizing electrode 9 and ionizing heater 10, the ionized cluster then being accelerated towards the substrate 6 (preferably moving) by a voltage applied between electrodes 9 and 5. The deposition apparatus is evacuated to 10<SP>-4</SP> - 10<SP>-7</SP>, the diameter of the hole is 1-30% of the crucible diameter, the voltage between 9 and 10 is 10-1000V and that between 9 and 5 is 10-10,000V. Preferred metals are Al, Cu, Au, Zn, Pb, Cr, Ni and Fe and the substrate may be of ceramics (e.g. Al 2 O 3 , steatite, forsterite, beryllia glass) or plastics (of which many examples are given, including reinforced resins). The coating may be followed by a vapour-deposition coating. In Examples, 2-7Á Cu is deposited on polyester (Ex 1 and 3) polythene (2 and 4) paperbase phenolic resin (5 and 7) glass-fabric base epoxy resin laminate (6), polyimide resin laminate (8) and steatite porcelain (10 and 12); 1Á Au is deposited on Al 2 O 3  (9 and 11); 500 Zn on polyethylene terephthalate (14); and 1,000 Al on polyester (13). Examples 15 and 16 disclose coating methacrylic resin with Al followed by a further layer of Al by vapour deposition (15) or ionized vapour deposition (16). The method may be used in the manufacture of printed circuit boards, using stencils (moving with the substrate) of stainless steel (Ex 3 and 11), Cr (8), or by coating, printing the circuit and etching (10). The substrate may be coated by two such cluster ion plating devices.

Title: Binary information transmission system
IPC: H04L27/12
Filed: 1963-02-08
Abstract: 1,013,163. Data transmission. STANDARD TELEPHONES & CABLES Ltd. Feb. 8, 1963 [Feb. 14, 1962], No. 5241/63. Heading H4P. In a data transmission system 1 and 0 bits are transmitted as discrete frequencies, the binary significance of the frequency being determined by reference to the preceding frequency. The three (or more) frequencies are regarded as forming a cyclic sequence ABCABC . . ., changes in one direction, e.g. A to B, representing binary 0 in the other direction, e.g. A'to C, binary 1. In the embodiment described the data controls the direction of rotation of a distributer which gates the frequency sources to the transmission line. Since there is a change of frequency at each bit, differentiation of the demodulated signals provides sync. signals for sampling the demodulated outputs. If adjacent received frequencies are not adjacent in the cyclic sequence a repetition requesting signal is sent to the transmitter.

Title: Improvements in or relating to control systems for polyphase alternating current electric motors
IPC: B66C13/26
Filed: 1944-03-21
Abstract: 583,820. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. March 21, 1944, No. 5279. Convention date, April 8, 1943. [Class 38 (iii)] In a control systen for a polyphase asynchronous motor for lowering widely vary - ing g loads, mean: are provided for unbalancing the stator circuits whereby the motor torque normally opposes the descent of said loads but at one setting tends to hoist a minimun load, at a torque sc small as to ensure against actual hoisting. The unbalancing of the stator is controlled by a tapped transformer T the connections of which to two stator terminals are changed by contactors operated by a drum controller, which also controls the main switch M, hoisting switch H, lowering switch D, the rotor circuits, and an electro-magnetic brake B, and has five "hoisting" and five "lowering" positions. In the first "lowering" position, position 1, Fig. 3, the motor tends to hoist an empty hook but the torque is too small to overhaul the gearing. In the second "lowering" position, reversal of torque is effected. With subsequent "lowering" positions a progressively closer approach to balance of the primary is obtained. The relay VR, having a delayed response to fall of rotor voltage, affords means for energizing the main switch M and the lowering switch D, following lowering operation, until the motor stops, thus supplementing the braking-action of the brake B by dynamic braking. At commencement of hoisting, one phase of the rotor winding is interrupted by the contacts b2 to afford low torque for taking up slack cable. In subsequent hoisting positions the interrupted rotor phase is completed and the resistances R2, R3, and R4 progressively excluded; the series relay SR affords delay in response of switch 2A, time-delay relays govern the energization of the switches 3A and 4A, and correct sequence of switching is ensured.

Abstract: 737,415. Coating with metals. ERIE RESISTOR CORPORATION. Feb. 25, 1953 [April 25, 1952], No. 5306/53. Class 82 (2). [Also in Groups XXXVI and XL (b)] Copper electrodes are deposited on barium titanate by gas plating- to form a condenser or a piezo-electric unit. A disc 1 of barium titanate is placed on a plate 14 in a chamber 13 the plate being maintained at a temperature of about 800‹ F. by electric heating elements 15. Inert gas, such as nitrogen, argon or carbon dioxide, is passed through the chamber from a container 6 via a regulator 7, a heater 8 (325‹ F. to 425‹ F.) and a valve 16. The gas removes absorbed oxygen from the titanate. By means of valves 16, 17 the flow of gas is then diverted through a carburetter 11, in which it picks up copper acetyl acetonate vapour, and a further heater 12. The vapour is kept below its decomposition temperature (455‹ F.) until it comes into contact with the titanate disc 1 on which the copper is deposited. Masks are used to confine the electrodes to the parts on which they are required.

Title: Improvements relating to heat-sensitive compositions
IPC: G03C1/498
Filed: 1960-02-15
Abstract: Solutions of copper salts of propionic, chloracetic, glycollic, and pyruvic acids free from extraneous ions are prepared by adding cupric hydroxide to an aqueous solution of the appropriate acid, diluting the slurry so formed, and clearing with an additional quantity of the acid.  Copper pyruvate decomposes on standing with evolution of a gas, producing a suspension.  A solution of copper trifluoroacetate was similarly prepared but no attempt was made to dissolve a small amount of undissolved cupric hydroxide.  Copper glycinate solution is prepared by adding cupric hydroxide to an aqueous solution of glycine, diluting the slurry, and adding a few drops of concentrated hydrochloric acid to clear the solution.  Suspensions containing cupric salts of malonic, a :a 1-oxydiacetic, or acetylsalicylic acid or copper formate are formed by adding commercial basic copper carbonate to aqueous solutions of the appropriate acid and heating gently to drive off carbon dioxide.  A solution of silver acetate is formed by slowly adding 10% acetic acid to a brown precipitate of silver oxide formed by adding aqueous sodium hydroxide solution to an aqueous silver nitrate solution.
