Title: Improvements in and relating to bituminous compositions
IPC: C08L95/00
Filed: 1949-03-22
Abstract: An organic nitrogenous base containing at least one basic nitrogen group, for use in aqueous solution as a primer for a solid to be coated with a bituminous material containing an oleophilic organic acid to produce a composition resistant to the action of water (see Group V), is obtained by hydrogenating a polyamino condensation product of an unsaturated aldehyde such as acrolein or its homologues with ammonia or an amine.  In an example, 22 parts by weight of acrolein are mixed at - 60 DEG  to - 70 DEG  C. with 90 parts of anhydrous liquid ammonia, and the excess ammonia is allowed to evaporate.  The residue is dispersed in alcohol, 5 parts of Raney nickel catalyst are added, and the mixture is treated for an hour with hydrogen under a pressure of 1000 lbs. per square inch at 100 DEG  C., low-boiling material being subsequently removed under reduced pressure.ALSO:A bituminous composition resistant to the action of water, is made by priming a solid, such as wood, cement, glass, metal, or mineral aggregate for road making, either basic such as limestone, neutral, or acidic such as granite or rhyolite, with an aqueous solution or dispersion of an organic nitrogenous base and then applying a coat of a bituminous material containing an oleophilic organic acid, so as to form in situ a reaction product at the interface between the solid and the bitumen.  The bitumen may be a pyrogenous or an air-blown bitumen, or a naturally-occurring asphalt or asphaltite.  The oleophilic organic acid is preferably a fatty acid having at least 12 C atoms in the alkyl group directly attached to the carboxyl group, e.g. stearic, polymeric oleic, linoleic, or linolenic acids or mixtures thereof obtained by the hydrolysis of fats or oils such as linseed or soyabean oil; alternatively, naphthenic acids of a molecular weight above 220 can be used.  The acid is present in an amount between 0.2 and 2.0 per cent of the bituminous material.  The base must have at least one basic nitrogen group, e.g. amines, especially polyamines such as triethylene tetramine, heterocyclic bases such as pyridine and its homologues, water-dispersible proteins such as egg albumin, casein, pectin, or gelatine, or a hydrogenated polyamino condensation product of an unsaturated aldehyde such as acrolein or its homologues with ammonia or an amine (see Group IV (b)). The base is used as a 0.01-0.1 molar solution which is applied to the solid in an amount equal to 1-5 per cent.

Title: Improvements in or relating to frequency discriminator circuits
IPC: H03D3/08
Filed: 1945-03-30
Abstract: 603,437. Frequency modulation ; automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 30, 1945, No. 8078. Convention date, April 1, 1944. [Class 40 (v)] A frequency discriminator circuit comprises a parallel resonant circuit tuned to a predetermined frequency, and, coupled to it, a second resonant circuit, tuned to the same frequency and comprising two condensers connected in series across a coil, the junction of the condensers being connected to one side of the first tuned circuit and the inductances in the tuned circuits being separately adjustable. The primary circuit 1, 2, Fig. 1, is connected in the anode circuit of the final intermediate frequency amplifier or the amplitude limiter of a superheterodyne frequency-modulated receiver. The secondary coil 2 is magnetically coupled to coil 1, and has two condensers 4, 5 connected in series across it. The inductances 1, 21 are varied by movable cones, and circuits 1, 2 and 21, 4, 5 are tuned to the I.F. The inductance of coil 2<1> is approximately twice that of coil 1, the condensers 2, 4, 5 being equal. The junction of condensers 4, 5 is connected to the high potential side of the primary circuit 1, 2. The anodes of two diode rectifiers 9, 10, which may have a common envelope, are connected to the terminals of the secondary circuit, while their cathodes are connected by a byepass condenser 13. The load resistances 14, 15 of the rectifiers 9, 10 are connected directly across the electrodes, the cathode end of load 15 being connected to earth. The audio-frequency is taken from the cathode end of resistance 14 through a coupling condenser 16, which may be followed by a de-emphasis network, or the condenser 13 may be made sufficiently large to provide the necessary de-emphasis. An automatic frequency control voltage may in addition be taken from the cathode end of resistance 14. In a modification, Fig. 2, the primary and secondary circuits 1, 2 and 2<1>, C1, C2 are coupled by the lead connecting the junction of condensers C1 and C2 to one side of circuit 1, 2 and if the condensers C1, C2 are not quite balanced, capacity coupling will also exist between the circuits 1, 2 and 2<1>, C1, C2, so that if the damping is small the necessary coupling will be secured with a very small unbalance. This is stated to alter the discriminator action by an unimportant amount. Specification 489,094 is referred to.

Filed: 1972-02-23
Abstract: 1377165 Data processing SIEMENS AG 23 Feb 1972 [7 April 1971] 8232/72 Heading G4A A programme controlled data processing system, e.g. for telecommunications includes two or more processor units VE1 and two or more memory units SP1, e.g. core stores, the units being duplicated so that, in case of an error, another unit can take over from the erroneous unit. If a processor unit VE1 wishes to connect with the storage units it transmits a static signal BE (i.e. of constant value), and a dynamic signal VH (i.e. voltage continuously changing between two values), either automatically or from a keyboard operated control panel GBF. If a memory unit is ready it emits a static signal BA and, on receipt of signals BE and VH, sends a dynamic signal VB to the processor unit which establishes the connection and a lamp 123 lights up. The unit VE1 normally connects to two storage units simultaneously using the same procedure, unless one storage unit is faulty. Blockage of a connection can be initiated by the processor units (automatically by stopping the BE signal or by a key TVS), and by the memory units (by stopping the BA signal or manually by keys TSp), and the result is indicated on lamps L7. If a connection is made to only one store when both stores are available then the connection is broken since the two stores are supposed to be in synchronism. To reconnect a storage unit which has previously been disconnected, a static signal is transmitted from that unit to all the processor units. Data is transmitted from the connected storage unit to the disconnected one before reconnection to ensure synchronism.

IPC: A43D8/04
Filed: 1962-03-02
Abstract: 1,031,292. Footwear making machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. Feb. 28, 1963 [March 2, 1962], No. 8293/62. Addition to 931,796. Heading A3B. The machine for shaping end portions of shoe uppers described in the parent Specification is modified in that clamping members 360, which press the uppers during moulding firmly against the front portion 302 of the mould, are mounted on a carrier, e.g. a swingable arm 356, so that they can be raised up clear of the mould while the upper is being fitted to it. In operation with both the mould and arm raised, Fig. 2, an upper is positioned on a work supporting inner mould or form 300 having a front portion 302 and movable rear portion 304. The arm 356 is then pulled down so that a pin 352 thereon contacts an abutment 310 and the mould 300, and casting block 306 on which it is mounted, are urged down against a spring-loaded plunger 412 to the operative position, Fig. 2, determined by a stop screw 414 (in a bar 320). At the same time a pre-set gauge 400 on the arm engages the top-line of the upper and depresses it to its correct position heightwise relative to the inner mould 300. If desired a gauge 430, Fig. 3, having adjustable arms 435 and suitable for use when different upper top-line heights are required at either side of the upper may be fitted to the arm 356. A power cycle of operations is then initiated as described in the parent Specification by the depression of a treadle causing among other operations the advance and closing of outer forming members 9 to clamp the upper against a plate 308, Fig. 1, and the admission of compressed air to a cylinder/piston device 368 causing the clamp members 360 to press and hold the forward part of the upper against the inner mould portion 302. The marginal flange forming members 71 act at the same time and pressure fluid is admitted via an inlet 328 to a piston/cylinder device 322 which operates a bell-crank lever 330 to push a hollow rod 334 sliding in bores in the portion 302 and casting 306 to engage the portion 304 at 340 and push it rearwardly to tension and mould the end portion of the upper. An electrical element 305 heats the portion 304. Finally the arm 356 is raised and the shaped upper removed from the inner mould 300. The machine includes screw/rod adjustment means 315, 313 for the initial position of mould portion 302, the rods 313 carrying an adjustable bridge member 408 over and against which the forward part of the upper is drawn and pressed by the operator. The casting 306 is pivoted at 314 so that mould 300 can be swung completely clear for replacement. Both clamps 360 and gauge 400 (or 430) are adjustably mounted on the arm 356.
