Title: Improvements in or relating to radio receivers
IPC: H03G3/26
Filed: 1933-10-06
Abstract: 411,351. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Starrett, J. S. ; Burnet Hill Road, Living- ston, New Jersey, U.S.A.) Oct. 6, 1933, No. 27570. Convention date, Nov. 1, 1932. [Class 40 (v).] Quiet automatic gain control is effected by a noise suppressor valve controlled by direct current variations in a gain control valve and controlling the operation of an audio-frequency amplifier. The grid bias of a low frequency amplifying valve 20 is, in the absence of signals, sufficiently great to prevent amplification owing to the current flowing through the noise suppressor valve 27 and the resistance R2 which is included in the grid circuit of valve 20. When a signal is being received this current no longer flows owing to the grid of valve 27 being biassed to cut-off by the current flowing in resistance R in the plate circuit of a gain control valve 26, which resistance is also in the grid circuit of valve 27. The control grid of valve 26 is fed with the output from an intermediate frequency amplifier 5 through a condenser 30 and potentials across the resistance R in its anode circuit are also used to control the gain of high frequency amplifiers, intermediate frequency amplifiers 5 and second detector 15. In the absence of signals, the valve 26 is biassed to cut-off and no current flows in the resistance R. Anode and screen-grid potentials for valves 5, 15, 20, 26 and 27 and grid bias for valve 26 are supplied from a potential divider as shown while a steady bias for the control grids of valves 20 and 27 is provided by cathode lead resistances 24 and R1 respectively, all of said valves being pentodes with a suppressor grid connected to the cathode.

Title: Process for the production of thickened oil with addition of wood oil and means therefor
Filed: 1930-09-17
Abstract: <PICT:0362545/III/1> Stand oil composed of a mixture of polymerized wood oil and polymerized linseed or like oil is obtained by dispersing wood oil preheated to near the point of polymerization in hot polymerized linseed &c. oil; gelatinization is thus prevented. For example, 5-30 gallons of wood oil preheated in a pot C are forced by a pump B into 100 gallons of hot polymerized linseed oil in a pot A may be through an immersed ejector nozzle.  The mixture is then circulated for the time desired through the pipe E, nozzles or perforated coils on a pipe F in the pot C, pipe D, pump B, and pot A and is finally discharged through a pipe N.  Advantageously carbon dioxide or other inert gas is supplied to the pots, e.g. to the pot A by a pipe S ending in a coil K.  Fumes are exhausted through an oil trap P on a pipe O dipping into a catchpot R.  The pot C is heated by the flue gases from the furnace K below the pot A.  The pump B may be replaced by an injector type of circulator operated by inert gas; or the oil may be blown from either pot to an overhead tank by inert gas, and allowed to flow by gravity to the other pot.

Abstract: 777,438. Electric igniters for fuzes. AKTIEBOLAGET BOFORS. Sept. 30, 1955 [Oct. 11, 1954], No. 27910/55. Class 9 (1). Electric igniters for ammunition fuzes comprise two conductors around the free ends of which an insulating body is cast with the bare ends connected by an electrically conducting coating on the body. To make the igniters, an electric conductor 15 having an insulating coating is wound around two overlapping plates 7, 8, Figs. 2, 4, so that the conductor passes through grooves 7a, 8a in opposed edges of the plates, the overlap being adjusted by screws 11, 12 extending through slots 9, 10. After winding, the screws are loosened and plate 7 is moved until the plates coincide leaving exposed loops 16, Fig. 4, which are then passed over hooks 17 of a wire-winding apparatus. Each hook has a gear wheel 19 meshing with intermediate gears 20, the end gear 19 of the apparatus being in mesh with a gear 21 rotatable by a crank 22 to twist the loops. After twisting, the upper end of each loop is cut off, the plates are inverted and the twisted parts are dipped in an insulating liquid 24, Fig. 5, to form beads. Each turn of the conductor 15 is then severed at the upper edges of the plates and the resulting igniters are placed in semi-spherical recesses in a plate of insulating material, as in Specification 777,437 where the beads are then planed off and finished. Finally, an explosive coating such as silver acetylide is applied to the beads.

[Also in Division G1] Apparatus for sensing vehicle speed comprises sensing means producing a signal of duration dependent on the time taken for the vehicle to travel a predetermined distance. As described, with reference to Fig. 2, the passage of a vehicle passing a detector of the electromagnetic or treadle type produces a pulse which energizes relay 22 changing over contacts 23 to allow capacitor 24 to charge to a potential dependent on the time the vehicle wheel takes to pass the detector. At the end of the time period relay 29 is operated by the differentiated pulse to discharge capacitor 24 into capacitor 31. The voltage across capacitor 31 is then indicative of the mean traffic speed. Relay 22 is a slow release relay to allow capacitor 31 time to change. In an alternative, Fig. 3, a transfer capacitor 41 is first charged from capacitor 24 and then used to charge capacitor 31. In a further embodiment, Fig. 4, two spaced sensing devices 51, 52 are used producing different amplitude pulses. Pulses from the first set a bi-stable circuit 59 which controls relay 22, and pulses from the second reset the bi-stable circuit and operate relay 29. A delayed reset device 60 is also provided to reset the bi-stable circuit in the event of the second sensing device not operating.

Title: Improvements in or relating to hydraulic shock absorbers
IPC: F16F9/26
Filed: 1929-09-20
Abstract: 338,653. White, A. E., (Delco Products Corporation). Sept. 20, 1929. Fluid-friction vibration - dampers. - An hydraulic shockabsorber for vehicles &c. comprises a casing 20, Fig. 2, having a fluid reservoir 26 and two cylindrical compression chambers 27, 28 containing respectively the head portions 44, 43 of a compound piston 42 adapted to be reciprocated by an arm 41 on a rock-shaft 32, the movement being controlled by pressure-relief valves in ducts affording communication between the chambers 27, 28, and is characterized in that each pressure-relief valve is provided with multiple springs so arranged that the restricted flow of fluid is varied according to the pressure in the compression chambers. A duct 70, Fig. 5, from the chamber 27 communicates through a relief valve 90, valve chamber 72 and passage 76 with a duct 71 from the chamber 28, the duct 71 in turn communicating through a relief valve 82, valve chamber 73 and passage 77 with the duct 70. Each relief valve 82 or 90 is slidably mounted on a pin 80, Fig. 6, and is normally acted upon by an inner spring 83, the end of an outer stronger spring 84 being spaced from the valve flange, so as to come into action only after an initial displacement of the valve. A reduced part 85 of the valve moves out of the duct 71 after the valve flange has engaged the outer spring 84, the fluid flow space being thus increased. The piston heads 43, 44 are each provided with a through passage controlled by a spring-pressed ball check valve 55, whereby the fluid in the compression chambers 27, 28 is replenished through passages 49, 50 from the reservoir 26, in order to compensate for leakage. The outer ends of the springs 56 of the check valves 55 may be adapted to snap into annular grooves in the interior of valve cages 53. The arm 41 engages wear members 47, 48 which are slidably mounted in the piston heads and are maintained in engagement with the arm by springs 68, 58.

Abstract: 392,222. Enamelling ; glazing ; glass manufacture. BOX, E. R., 78, Hatton Garden, London, WHITE, N. W., Sneyd Works, Burslem, Staffordshire, and JOHNSON, MATTHEY, & CO., Ltd., 78, Hatton Garden, London. July 13, 1932, No. 28807. [Class 56.] A process for the production of mottled or marbled effects on ceramic ware, glass, enamelled iron ware, or the like consists in using enamels or glazes which comprise either (a) a mixture of a finely-ground portion and a more coarsely-ground portion, the fusibilities and colours of the two portions being preferably different, or (b) a single powder the particles of which are uniform and are coarser than 0À02 millimetre in diameter, or (c) a mixture of graded powders of one or more colours. The enamel may be applied by dipping, spraying, or dusting, or by means of transfers. The article is then fired at a temperature at which the more readily fusible constituent runs freely, and the less readily fusible constituent then spreads in streaks and blotches. The required effect may also be obtained by using a relatively coarsely-grained material which has been sieved with a 40-mesh and a 100-mesh screen. When the material is fired at a relatively low temperature, a veined or " crinkled " effect is obtained. If fired at a high temperature, a smooth, dense, uniform colour is obtained. In either case, the material may be applied to the article by means of transfers. Specification 385,221 is referred to.
