IPC: F41A21/30
Abstract: 106,851. Wilson, G. C. June 2, 1916. Machine guns; sound of discharge, modifying.- Relates to means for silencing the discharge of machine guns, rifles, &c., and for concealing the flash, of the kind comprising a casing divided by apertured partitions into compartments through which the gases pass following the passage of the bullet, and a spring-controlled flap or shutter which closes a straight path through the casing, thereby cutting off the flame and diverting the gases. The invention comprises an arrangement embodying a central chamber having partitions with central apertures, movable spring-controlled flaps or shutters between the partitions operated by the pressure of the discharge gases acting upon a disk or cone, and an outer casing divided by longitudinal partitions arranged to form a zigzag path for the gases. As shown in Figs. 2 and 3, the device comprises a box or outer casing A of flattened oval section with funnel-shaped ends A<1>, A<2>, the end A<2> being clamped at A<3> to the muzzle B of the gun. An inner chamber C formed by two side plates C' is provided, and is divided into compartments by partitions M having central apertures M<1> permitting passage of the bullet. Flaps or shutters F, pivoted at F' in longitudinal channels E, are controlled by a pair of slidable bars D slotted at D<1> to receive the stems of the flaps. The bars D are secured at the inlet end of the casing, to a cone G combined with a plate H controlled by springs J in order normally to keep the flaps open, as shown. When the weapon is fired, the bullet passes through the various apertures provided, whilst the pressure of the discharge gases acts upon the plate H and cone G, forcing the bars D to the left, thereby closing the flaps F, as shown in broken lines at F<2> in Fig. 3, and cutting off the flame and gases. These are deflected into zigzag passages formed by longitudinal partitions N leading to side outlets A<5>, thus reducing the pressure and velocity of the gases and eliminating the flame. The device is detachable and may be taken to pieces in order to replace damaged parts.

Title: Safety means for electrically heated appliances
Inventor: KAY ARTHUR SELWYN
IPC: H01H37/00
Filed: 1964-03-17
Abstract: 1,095,264. Thermal switches; fusible cutouts. JOSEPH LUCAS (INDUSTRIES) Ltd. March 12, 1965 [March 17, 1964], No. 11165/64. Headings H2B and H2G. A safety device for use in electrically heated appliances comprises an electrically conducting wire link connected in series with a thermostatic switch, on which it is mounted. The wire link is of such dimensions as to offer negligible resistance to the passage of current in the heating circuit but is formed of a material which will melt to break the circuit when it reaches a predetermined temperature which is substantially higher than that at which the thermostatic switch should operate but lower than the temperature at which damage to the appliance would occur. It thus melts and breaks the circuit if the thermostat fails to operate and prevents damage to the appliance.

Title: Improvements in card clothing for rollers of textile machines
Inventor: GOODALL JEFFREY
IPC: D01G15/84
Filed: 1963-03-21
Abstract: 1,009,139. Card clothing. JOSEPH SELLERS & SON Ltd. May 8, 1964 [March 21, 1963], No. 11207/63. Heading D1N. Card clothing has wire teeth that project above a foundation at a forward angle to produce the best stripping action and with front edges inclined to form faces at an angle providing the best carding action, these faces being produced by shearing or cropping the teeth so as to give the faces a surface roughness while leaving the rear edges of the teeth comparatively smooth. The rough forward faces 4 improve the holding properties of the wire during carding, but the other smooth surfaces, such as 5, allow the stripping properties to be unimpaired. The wire is preferably of rectangular section with a front-to-rear dimension approximately three times that of the width. A "knee" may be formed in the wire or it may be straight. Owing to the teeth lying at a sharp angle in the foundation the crowns project beyond its undersurface and a layer of sponge rubber or other material may be applied to the underface.

Title: Improvements in or relating to electronic valve circuits
Inventor: GILLESPIE ARTHUR BLACKLEY
IPC: G01S7/282
Filed: 1948-04-23
Abstract: 639,815. Pulsing carrier frequencies; valve circuits. MINISTER OF SUPPLY. April 23, 1948, No. 11208. [Classes 40 (v) and 40 (vi)] The normal damping of a tuned circuit, set in oscillation by shock excitation, is neutralized by connecting it to a negative resistance tube having a load resistance shunted by a capacity in its cathode lead. As shown, the tuned circuit 13, 14 is connected in the anode circuit of a valve 7 which is normally conducting, but is blocked when a negative pulse is applied at 6 to its control grid. The circuit 13, 14 is also connected to the control grid of a valve 17 arranged as a cathode follower and having a capacity 18 shunted across its cathode resistor 19. When the valve 7 is blocked, an oscillation appears in the circuit 13, 14 and damping is neutralized by the negative resistance effect of the valve 17, regulated by the variable screen resistance 20. When the valve 7 is blocked, a valve 8 coupled to it by a common cathode resistor 28 is opened. The back coupling afforded by the condenser 11 maintains the valve 7 blocked until the charge on the condenser 11 leaks away, whereupon the valves 7, 8 revert to their former condition and the oscillation in the circuit 13, 14 is damped out by the conductivity of the valve 7. Anode supply to the valves 7, 8 is taken from the cathode of a valve 16 connected across the supply source in series with resistors, the grid of the valve 16 being connected to a voltage divider also connected across the supply source. The frequency of the tuned circuit 13, 14 is initially adjusted.to agree with that of a quartz crystal 22 by throwing the switches 9, 21 into the dotted position. The switch 9 then applies a more positive bias to the valve 8, causing this valve to pass current and the valve 7 to be blocked. The tuned circuit is maintained in continuous oscillation by the negative-resistance valve 17, which passes the oscillations from its anode through the crystal 22 to a rectifier 23, the load resistor of which is associated with a magic eye indicator 24. The condenser 14 is then adjusted until the indicator shows a maximum.

Title: A method of treating keratinic fibres to improve their resistance to felting
IPC: D06M13/364
Filed: 1963-03-21
Abstract: Keratinic fibres, e.g. wool, are felt-proofed by treating them with an aqueous solution of an alkali metal salt of N-dichloroisocyanuric acid having a pH of 6.5-9 continuously while maintaining them in motion in the solution.  The treating solution may contain 20-100 g per litre of the alkali metal salt of N-dichloroisocyanuric acid and is preferably maintained at a temperature of 5-35 DEG C.  The solution may also contain an anionic, nonionic or cationic surface active agent, e.g. a condensate of ethylene oxide with buryl alcohol. The fibres may subsequently be treated with acidifying, dechlorinating, rinsing and softening baths in any order, the liquid taken up by the fibres in passing through one bath being at least partly removed before passage through the next bath, e.g. by the use of wringers or suction apparatus.  The acidifying bath may be an aqueous solution of a mineral or organic acid, e.g. hydrochloric acid, having a concentration such that the solution has a pH of 1.5-5.  Suitable reagents for use in the dechlorinating bath are sodium bisulphite and sodium hydrosulphite and the softening agent may be a quaternary ammonium halide or an anionic or nonionic compound. The speed of passage of the fibres through the different baths may be between 0.5 and 15 metres per minute.  The process may be carried out in a smoothing machine comprising a series of tanks in which the fibres circulate to become impregnated with the liquid contained therein, each tank containing a perforated drum partly immersed in the liquid and rotating about its axis against which the fibres are applied, complete and homogeneous impregnation of the fibres being ensured by drawing the treatment liquid into the perforated drum and discharging it at the upper part of the tank. The keratinic fibres may be treated in the form of combed or carded yarn, raw wool, skeins, woven or knitted fabrics or ready to wear articles.

Title: Improvements in or relating to photographic developing apparatus
IPC: G03D5/00
Filed: 1964-03-18
Abstract: 1,034,563. Photographic developing apparatus. W. ZINDLER. March 18,1964 [April 1, 1963], No. 11455/64. Heading G2A. [Also in Division G1] A photographic developing apparatus has means for guiding a photographic sheet along the liquid surface so that only one side is wetted, the apparatus also having a constant liquid level arrangement comprising a supply container connected to both the bath of liquid and to a reserve tank. In the form shown, the bath 1 containing the developing liquid has a number of web members 6 extending across its lower part. The generally flat upper edges 15 of these webs define the position of the liquid surface. Photographic sheets to be developed are fed into an inlet 2, whence they are guided across webs 6 so that they are wetted on their under side only. They are then guided out of the apparatus through an outlet 3 and between transport rollers 4, 5. If a transfer process is to be effected, a second inlet 28 is provided, through which a copy sheet can be inserted and passed below the bath 1, so that it has a completely dry path until it meets the negative and they are pressed together between rollers 4, 5. A supply container 8 is provided within the bath 1, its walls 9, 10, 11 being parallel to the bath and web members. A short pipe 12 extends downwards from the base 11 to below the liquid level in the bath. Another pipe 13 extends downwards to just above the edges 15 of the web members, and upwards into the supply container 8 almost to its top wall 17. A much wider pipe 19 connects the lower part of the container 8 to a reserve tank 20 situated below the apparatus. A connecting pipe 26 joins pipe 19 directly to the bath. Tank 20 is flexible, and can be compressed by a movable plate 23. When plate 23 is raised, tank 20 is compressed and the liquid forced upwards into both container 8 and bath 1. As soon as the liquid level in the bath reaches the bottom of pipe 13 it can rise no further. During use, if the liquid level of the bath falls slightly due to the amount carried away by the passage of the film sheets, it is automatically restored by replenishing liquid from the full supply container 8. When use of the apparatus is no longer required, plate 23 is lowered again, and the liquid flows back into tank 20 through both pipes 19 and 26, so that container 8 and bath 1 are both completely empty.
