Abstract: 382,280. Spray-producers. DENSTON, W. J., 21, Masshouse Lane, Birmingham. July 15, 1931, No. 20280. [Classes 69 (iii) and 135.] A nozzle for hose &c. of the kind in which the nozzle must be held in the hand to allow liquid to flow through it and the flow ceases automatically when the hand is removed comprises two members having relative movement of first sliding and then a alight rotation. The nozzle comprises a body a provided at one end with a chamber for a ball valve c which engages an annular seating a<3>, its travel being limited by a bar a<4>. From the point a<4> the body is reduced to form a sleeve a<5> which fits a hollow plunger d<1> screwed into a nozzle member e and carrying a pin d<3> engaging a cam slot a7 in the sleeve a<5>.

Alternatively, the strip may be segmental, or may be divided by the slot B into halves which may be segmental, or the blocks A may be separate, or each block may be integral with an adjacent block in the other row.
Patent GB-203416-A (GB)
Abstract: 203,416. Beldam Packing & Rubber Co., Ltd., and Robinson, G. H. June 13, 1922. Materials, special.- A rubber or like disc valve is made by extruding a strip of the material and forming the valve therefrom, the whole being subsequently vulcanized so that contiguous parts are united. Reinforcing materials may be used in the extruded strip. A rubber strip a provided with wire, cotton, fibre or other reinforcing material is extruded in such a manner that the latter forms a core surrounded by rubber. This strip, is coiled upon a mandrel spirally so as to form a flat disc, the ends b, c being scarfed to give a circular outline. The whole disc is then vulcanized. The strip may be treated or coated before being wound.

Title: Improvements in or relating to radio-receiving circuits comprising means for automatic gain control
IPC: H03G3/22
Filed: 1954-07-12
Abstract: 785,031. Automatic gain control; muting; limiters. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 12, 1954 [July 10 1953], No. 20384/54. Class 40 (5). Automatic gain control. Intermediatefrequency signals are fed from the primary 3 of the I.F. transformer 3, 4, to an A.G.C. diode 9. The diode 9 is shunted with a load resistor 10 and its cathode is connected to a potentiometer, comprising resistor 12 and gas-discharge tube 23, across the H.T. supply. The A.G.C. voltage is applied to earlier stages in the receiver via high-value resistors 13, 14 and resistor 16, delay being provided by a diode 15 the anode of which is connected to the join of resistors 14, 16. A negative bias is applied to the cathode of the diode 15; it constitutes the initial bias for the gain-controlled stages and may be obtained by rectification from the A.C. heater supply. The delay voltage, substantially that across gas-discharge tube 23, is made large, as is also the gain of the preceding I.F. amplifier 2, the signal detector 5 being tapped well down the secondary 4 of the I.F. transformer 3, 4. In this way a load 6 of relatively low impedance may be used. Muting and noise limiting. Rectified audio signal from the load 6 is applied via a blocking condenser 17 to the cathode of a diode 7, the anode of which is connected to one of the output terminals 8 via a further blocking condenser. The cathode of the diode 7 is connected to a potentiometer comprising resistors 19, 20 across the H.T. supply; its anode is connected to a further potentiometer comprising resistor 21 and the anode-cathode path of a valve 18, across the H.T. supply. The grid of the valve 18 is connected, via a series resistor 24, to the join of resistors 13, 14. In the absence of a signal, a positive potential is applied to the grid of the valve 18, grid current occurs and the anode potential is low, thereby rendering diode 7 non-conductive. When the potential on the A.G.C. line becomes sufficiently negative, the valve 18 is cut off, the anode potential rising and rendering the diode 7 conductive. A condenser 22 in shunt with the valve 18 prevents the anode potential of the diode 7 following the cathode potential on positively-going noise impulses, which are thereby limited.

Title: Pneumatic tyre and wheel assemblies
IPC: B60C3/00
Filed: 1972-05-03
Abstract: 1435915 Lubricants DUNLOP Ltd 27 April 1973 [3 May 1972 2 Sept 1972] 20502/72 Addition to 1359461 Heading C5F [Also in Division B7] In a pneumatic tyre and wheel assembly means are provided which enclose at least one ingredient of a lubricant composition, and the remaining ingredient or ingredients of the composition are located directly in the inflation chamber of the assembly without any enclosing means, the enclosing means being adapted to automatically release the or each ingredient contained therein into the inflation chamber upon deflation of the tyre during running, thereby to enable all the ingredients to mix and form the composition so that the latter can lubricate contacting parts of the interior surface of the tyre thus preventing tyre destruction and enabling continued running the deflated state. An enclosed ingredient of the lubricant composition may be a volatile liquid which will evaporate during running of the deflated tyre so as to partially reinflate the tyre, or alternatively a substance, e.g. an acid, which will react with an ingredient, e.g. calcium carbonate, not in the enclosing means to produce a gas to partially reinflate the tyre. In one embodiment water as a volatile liquid is contained in the enclosing means and a solid gelling agent for the water, e.g. a cellulose derivative or a carboxyvinyl polymer is either carried loose in the inflation chamber or applied as a coating to the surface of the inflation chamber. In another embodiment a gel formed of non-volatile ingredients, e.g. including a poly(oxyalkylene)- glycol, is applied as a coating to the interior surface of the tyre beneath its tread, and the enclosing means contain volatile ingredients and also a dilatant for breaking down the gel. Numerous other suitable ingredients and formulations for the lubricant composition are given in the Specification. Reference has been directed by the Comptroller to Specifications 1,359,467 and 1,359,468.
