Title: Improvements in and relating to signal means for hat formers
IPC: A42C1/02
Filed: 1927-06-14
Abstract: 275,135. Robinson, J. S. June 14, 1927. Bodies, forming. - Relates to hat-forming machines of the kind in which the material is wrapped on a former, and consists in means for giving a signal to the operator when sufficient material has been wound comprising a member engaging the material being wound and rocked to operate a signal when a predetermined thickness has been reached. A strip of material A taken from a carding machine is wound, in the known manner, on a double cone 4 supported on rollers 3. Adjacent to the bases of the cones are a pair of wings 14 carried by an arm 10 fixed to a sleeve rotatable about a fixed shaft 5, the sleeve also carrying an arm 8 secured to a weight 9. Wheels are rotatable about the two ends of the shaft 5, one a ratchet wheel having an arm 18 adjacent to the under side of the arm 10, urged clockwise by a spring 19, but normally prevented from movement by a pawl 24. The other wheel 29 is normally held by a spring 32 so that an arm 31 mounted on the wheel is below the arm 8. To the arm 8 is adjustably secured an arm 27 carrying a pin 26 projecting into an eye 25 on the tail of the pawl 24. The arm 10 normally rests on a stop 36 which is adjusted to give a predetermined clearance between the cones and the wings 14. In operation, when, during the winding, the material on the cones engages the wings and pushes these outwards until the pin 26 releases the pawl 24, the arm 18 on the ratchet wheel lifts the arm 10 and causes the arm 8 to ring a bell 21, signalling that sufficient material has been wound for one pair of hats. Before restarting the machine to wind another pair, the mechanism is reset by the operator pulling on a handle secured to a cable 33, which rotates the wheel 29 to lift the arm 8, the wheel 29 then being returned to normal position by the spring 32.

Title: Thermoplastic gas-expanded material
IPC: C08J9/00
Filed: 1962-04-26
Abstract: A closed cell thermoplastic gas-expanded material comprises a vulcanized intimate uniform mixture of (A) a blend of a polyvinyl chloride resin and butadiene-acrylonitrile copolymer rubber, and (B) an ABS polymer. Portion (A) may comprise 20 to 80% of polyvinyl chloride resin and preferably 40%. The polyvinyl chloride resin may be polyvinyl chloride itself or a copolymer with e.g. vinyl acetate, vinylidene chloride or diethyl maleate or a mixture of polyvinyl chloride with polyvinyl acetate.  The copolymer rubber may be partly or entirely cross-linked or high-gel rubber.  The ABS polymer generally contains 15 to 30% acrylonitrile, 15 to 40% butadiene and 40 to 60% styrene. It may be a graft polymer of acrylonitrile and styrene or polybutadiene to which additional amounts of styrene-acrylonitrile resin and butadiene-acrylonitril copolymer may be added. Portion (B) may alternatively consist of a physical blend of acrylonitrile-styrene and butadiene acrylonitrile copolymers. A preferred material for (B) is a latex blend of divinylbenzene cross-linked butadiene-acrylonitrile copolymer, a graft copolymer of styrene and acrylonitrile on polybutadiene and a styrene-acrylonitrile resin. Dioctyl phthalate plasticizer may be added. Azodicarbonamide, p,p1-oxybis (benzene-sulphonyl hydraxide) and dinitrosopentamethylene tetramine are suitable blowing agents. Expanded material is obtained by effecting partial cure at 275 DEG to 305 DEG F., sulphur or sulphur-donating agents being present, and then heating forther at 310 DEG  to 360 DEG F. to complete the cure and to decompose the blowing agent. Usually this heating is carried out while the material is being calendered into a sheet, e.g. by two passes through a floating platen sponge press, antioxidants and stabilizers e.g. nonyl phenyl phosphite and cadmium stearate may also be added to the mixture. In an example the sheet obtained is heated and moulded to form a baseball cap.ALSO:A baseball cap is obtained by moulding or vacuum-forming a sheet of closed-cell thermoplastic gas-expanded material which comprises a vulcanized intimate uniform mixture of (A) a blend of a polyvinyl chloride resin and butadiene-acrylonitrile copolymer rubber and (B) an ABS polymer (see Division C3).  The expanded material retains its cellular structure.

Title: Improvements in or relating to radio receivers
IPC: H03G3/26
Filed: 1934-05-30
Abstract: 440,483. Valve circuits for wireless reception. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. May 30, 1934, Nos. 16188 and 16189. Convention dates, May 30, 1933 and Aug. 17, 1933. [Class 40 (v)] The grid of a high-frequency amplifying valve 1 is, in the absence of signals, positively biassed by a battery B through the resistances R, R <1> and the tuned circuit L, C, the latter being damped by the flow of grid current and hence of small amplification. Signals are applied to the circuit L, C and a circuit L<1>, C<1>, the latter feeding a diode rectifier 2 with load resistance R which produces a delay voltage on the anode of the diode due to the flow of the grid current therethrough. As the signal strength increases, the D.C. potential developed across R opposes that due to the battery B and the amplification of the valve 1 rises until its grid begins to become increasingly negative for the purpose of automatic volume control. The normal muting action may be counteracted by opposing the grid bias due to the battery B with a potential due to a cathode resistance R<111> which is normally short-circuited by a switch D. The switch D may be coupled to a wave-change switch so that the muting is ineffective on short waves.

Title: Barbed wire machine
IPC: B21F25/00
Filed: 1967-04-10
Abstract: 1,144,870. Making barbed wire; rolling. AMERICAN ENG. CO. Ltd. 10 April, 1967 [19 April, 1966], No. 16224/67. Headings B3E and B3M. A machine for making single strand barbed wire having a main strand and barbs wound thereon comprises a pair of wire forming rollers, means intermittently driving said rollers to advance and form the main strand of wire, and means for winding barbs on the main strand, the rollers at all times engaging the main strand to advance and precisely position it in relation to the barb winding means, the rollers also functioning to flatten the main strand at those places on which the barbs are to be wound. A line wire strand 56 is flattened to oval cross-section by intermittent feed rollers 52, 53, grooves 58, Fig. 14, in the rollers 52, 53 being interrupted by pairs of notches 59 to leave portions 60, Fig. 11, of the wire of circular cross-section separated by oval section portions 61 around which the barbs are wound. Three pairs of notches 59 are spaced around each roll 52, 53 and the rolls are rotated 120 degrees at a time by crank, link and braked ratchet means, Figs. 5-8 (not shown), from a main drive shaft 15. Barb forming wire 67 is fed to the wire 56 from two sides thereof by roller assemblies 70 and through guides 71 to a barb winding head 72 and barb cut-off knives 73. The roller assemblies 70 each includes a pair of rollers intermittently driven by eccentric, connecting rod and ratchet means, Fig. 16 (not shown), driven from the main shaft 15. The rollers serve also to flatten that side of the barb wire 67 which is to contact the strand wire 56 about which it is wound. The winding head 72 includes, Fig. 19, a hollow bar 145, through which the strand wire 56 passes, carrying axially projecting fingers 146 and rotated by a gear 135, driven from the main shaft 15, to wind the barbs from the wires 69. The bar 145 and thus the fingers 146 are suitably projected and retracted by a face cam 136 on the gear 135. The barbs are cut off after winding by the knives 73 which are moved forward by an eccentric, Fig. 20 (not shown). The completed barbed wire 56 passes over a pulley 180 on a spring-urged pivoted arm 181 to take up slack, around a driven pulley 176, over an axially reciprocated pulley 160 and on to a reel 163 rotated through a slip clutch. The arm carrying the pulley 180 may be positively oscillated by cam means, Figs. 24, 25 (not shown), for high-speed operation.

Title: Receiver system with anti-jamming device
IPC: H03G3/34
Filed: 1964-04-20
Abstract: 1,062,433. Interference suppression in radio receivers; pulse radar. COMPAGNIE FRANCAISE THOMSON-HOUSTON. April 20, 1964 [April 18, 1963], No. 16360/64. Headings H4D and H4L. In a pulse radar receiver the gain of the main channel is varied by a voltage derived from two control channels, different time delays are imported to the signals in the three channels, and means ensure that the main channel gain control is effective only when an interfering signal is present. A higher wanted signal-tointerference ratio ensues and there is a constant false alarm ratio. In the embodiments the wanted pulse of duration t is jammed by an interfering pulse of duration T > t, the main channel (3, Fig. 1) incorporates a signal delay t (delay line 8), the first control channel (1) affords no delay and the second control channel (2) incorporates a signal delay 2t (delay line 9). Signals at I.F. pass via a filter (5) of bandwidth corresponding to pulse duration t and a linear amplifier (4) of wide dynamic range (the amplifier incorporating a limitor to restrict the input signal level to that below which the amplifier is linear), to the three channels. The main channel (3) comprises a set of n controlled amplifiers (A3 1  ... A3 n ), each being of similar circuitry to one amplifier (A3 1 ) which comprises an amplifier (13 1 ) feeding a stage (16 1 ) controlled by an output voltage (VR 1 ) via a switch (15 1 ), the control being such that there is no output current if the output voltage is less than a predetermined value and the stage operating in class B for no-signal input and in class C when there is a signal input, and the output voltage being obtained from voltages (ŒV1 1 , ŒV2 2  from corresponding sections (A1, A2) of the first and second control channels respectively. The first control channel comprises similar sections (A1 1  . . . A1 n ) preceded by a swept-gain amplifier (7); the first section (A1 1 ) incorporates a non-linear amplifier (12 1 ) feeding the following section and producing voltages (ŒV 1 ) which are proportional to the signal level in that section multiplied by a coefficient such coefficient being adjustable. The second control channel sections (A2 1  ... A2 n ) are similar. Switches (15 n ) are controlled by the output of an OR circuit (50) fed with the outputs of similar units (31, 41) in the main and first control channels; one such unit (31) includes (Fig. 3) a detector (33), a " slicing " circuit (34) controlled by upper (36) and lower (35) level threshold voltages and a subtraction circuit (39) fed directly and also fed via a " double time-constant " differentiator (38). It is stated that a switch (15 n ) causes the duration of the gain control voltage (VR 1 ) to coincide with that of the jamming signal in the corresponding section (A3 n ). In another embodiment (Fig. 4) the control channels each comprise one section only, the gain control voltages for the amplifiers (A3 1  ... A3 n ) being the same.

Abstract: A composition having improved toughness, i.e. greater impact strength, higher elongation and greater flexibility than polystyrene comprises polystyrene having an intrinsic viscosity greater than 10 and a rubber-methyl methacrylate graft copolymer containing a major proportion of rubber.  The graft copolymer is obtained by polymerizing methyl methacrylate in the presence of rubber, in solution or emulsion.  For example, a non-ionic emulsifier is added to an ammonia-stabilized rubber latex, methyl methacrylate added and the mixture polymerized at room temperature in the presence of a cumene hydroperoxide-polyamine redox system. The graft copolymer may be separated by fractional precipitation. The composition may be prepared by mixing the solids on heated rollers, e.g. at 160 DEG  C., by mixing emulsions or solutions, or by dispersing the finely-divided graft copolymer in monomeric styrene which is then polymerized.ALSO:A composition having improved toughness, i.e. greater impact strength, higher elongation and greater flexibility than polystyrene comprises polystyrene having an intrinsic viscosity greater than 10 and a rubber-methyl methacrylate graft copolymer containing a major proportion of rubber.

Title: Improvements relating to projectile fuzes
IPC: F42C1/06
Filed: 1940-11-12
Abstract: 577,935. Projectile fuzes. SMITH, W. H. Nov. 12, 1940, No. 16402. [Class 9 (i)] The case of an " Allways " fuze for projectiles is made of sheet metal, in two parts c, m, seamed together, the part c having a lateral recess h in which is housed the conical spring g by which the safety cross-pin f is ejected. The cross-pin is normally locked by an inertia-actuated device which releases the pin when the gun is fired. As shown, the firing-pin d is supported on a light spring q in a primer-carrying cylinder p, and is traversed by the cross-pin f. The pin f is normally retained by a pin on a resilient member k struck up from a ring l which is clamped in the seam of the casing. A hand withdrawn bar o prevents accidental release of the pin j. Alternatively, the cross-pin f is secured by an ordinary split-pin passed through the end of the cross-pin. According to the Provisional Specification, the inertia-operated arming device is a spring band encircling the fuze casing and engaging the head of the pin f.
