Patent GB-624633-A (GB)
Title: Improvements in and relating to the treatment of fibrous material
IPC: D06B3/02
Filed: 1946-10-08
Abstract: <PICT:0624633/IV (c)/1> Loose fibrous material and a liquid reagent are fed continuously into a vertical conduit and the discharge of the material is retarded whilst the liquid is permitted unrestricted discharge except for the resistance offered by the fibrous material, so that the liquid flows continuously through the material.  The inlet of the conduit is arranged higher than the outlet so that a head of liquid is formed whereby the material is compacted. Apparatus comprises a substantially vertical conduit 10 and a substantially horizontal outlet 16 which leads into a duct 22, the angle of which may be adjusted to vary the resistance offered to the discharge of the material.  Liquid is fed with the material into the top of conduit 10 and the material is compacted in the conduit by the head of liquid 52.  The liquid flows freely through the material and after passing through a slot between the duct 22 and its cover 30, is caught in the basin 32 from which it is pumped through the heat exchanger 36 back to the top of the conduit 10.  The Specification as open to inspection under Sect. 91 refers also to the treatment of fibrous materials in rope form.  This subject-matter does not appear in the Specification as accepted.

Title: Filler valve for gas tank of a gas lighter and method of making the  same
IPC: F16L37/40
Filed: 1971-06-29
Abstract: 1359859 Filler valves for gas lighters A RACEK 29 June 1971 [1 July 1970] 30484/71 Heading F4F A filler valve for the tank of a gas-fuelled lighter comprises a valve member 4, a resilient valve seat ring 6 and a helical spring 3 guided in a bush 2 which is formed integrally with and extends into the fuel tank from its plastics wall 1 such that, in use, the spring biases the member 4 to make sealing tight contact with the resilient ring 6 while a shank of the member 4 extends through the ring into the entry aperture for a filling conduit 14 so that the valve can be opened by the end of the conduit 14 before the end actually bears in sealing-tight relationship on the seat ring thereby to allow improved venting of the tank during filling. The ring 6 which makes a tight seal with the wall 1 is retained in place by a shoulder 7 of the wall and a retaining ring 8 which in turn is held by a peripheral shoulder of the wall. A conical portion 9 of the bush wall serves to limit the displacement of the valve member 4 and grooves 10 are formed in the bush wall at this point and further grooves 11 are formed in the outer end of the shank of the valve member to increase the passage cross-sectional area. A method of making the valve is also described and Fig. 1 shows in its right half the starting condition and in its left half the finished condition. With the filler entry aperture uppermost the member 4, ring 6 and ring 8 are placed in the aperture and the periphery 12 of the wall bent inwardly to hold the assembly in place. Then the tank is inverted, the spring 3 inserted and the periphery 13 of the bush also bent inwardly so that by this method the member 4 does not have to be inserted against spring force. The tank wall may be transparent.

Title: Device for Measuring Inclination of a Surface
IPC: G01C9/18
Filed: 1967-07-03
Abstract: 1,185,245. Measuring inclination electrically; recording apparatus. TOKYO KOGAKU KIKAI K.K. July 3, 1967 [July 12, 1966], No.30517/67. Headings G1J and G1N. A device for measuring the variation from the level at intervals across a surface, e.g. the bed surface of a machine, comprises an inclinometer 101, Fig. 4, including a pendulum 102 which alters the coupling between an excitation coil 106 and two secondary coils 107, 108 by an amount dependent on the inclination. The coils are connected, with resistors 109, 110 in a bridge circuit whose out of balance voltage Vt, proportional to the inclination, is supplied, via amplifier 111, to a servomotor 112 whose shaft 201 is rotated by an amount dependent on Vt. To obtain this rotation the shaft is connected to the slider 114 of potentiometer 113 from which a voltage V p  is fed back to the amplifier 111 to balance the input voltage Vt from the bridge. The shaft is also connected via an electromagnetic clutch 200 to a thread wheel 205 of a pen recorder which is thereby moved transversely across a stationary sheet 307 by an amount dependent on the inclination measured. In operation the measuring cycle is automatically controlled by cams 406, 407, rotated through 360 degrees per cycle by a motor 403, which operate switches 408, 409, 410. At the beginning of a cycle the measuring bridge is short circuited. Immediately after a start switch 401 has been closed the clutch is energized to connect the motor shaft 201 to the wheel 205. The switch 410 short circuiting the bridge is opened so that the voltage Vt is supplied to the servomotor which then drives the pen to a corresponding position. The clutch is then de-energized and the bridge again short circuited so that the motor shaft returns to its 260 portion but the pen remains in its displaced portion. Finally rotation of the cam 406 causes a lever 411, carrying at its upper end a pawl 415, to be moved vertically upwards so that the pawl 415, latching with a ratchet wheel 308 on the shaft of roll 310 carrying the sheet 307, causes the sheet to be fed along for a given length, the pen making a longitudinal trace during this movement. The motor 402 is finally de-energized leaving the apparatus ready for the next cycle when the inclinometer has been moved to an adjacent position along the surface.

Abstract: 757,615. Bells. HARRIS, I. R. Feb. 4, 1955 [Nov. 7, 1953], No. 30882/53. Class 13 [Also in Group XXV] The double - acting striking mechanism of a cycle bell comprises a trigger lever 1 and a hammer lever 7 which are pivoted intermediately of their ends at 1a, 8 and are connected by a U-shaped wire or strip spring 9 to provide a toggle action, the spring being anchored at the end of the trigger lever adjacent the hammer lever and at the remote end of the hammer lever in such a way as to tend to force the points of anchorage apart. The trigger lever is associated with a return spring 6 and its movement is restricted by a slot 5 in a mounting plate 2. In operation, movement of the trigger lever causes compression of the spring 9 and the hammer lever is impelled to an alternative position with a velocity sufficient to overshoot a rest position and strike the bell. The same action takes place during the return movement of the trigger lever. A detachable clip for securing the bell to a handlebar is also described (see Group XXV).

As the join in the disc is turned into the gap the inductance of the choke rises suddenly. The rate of rise of inductance can be varied by tapering the join between the two materials as shown in Fig. 3a by varying the width of the poles 7 as shown in Fig. 3b or by having a gradual transition between the two materials by a mixture of iron powder and aluminium powder combined by an adhesive.

[Class 53] [Also in Group XL (a)] An electron beam tube for detecting infrared rays has a target comprising a multiplicity of physically discrete thermocouples T mounted on an electrically conductive base or signal plate P. Heat from the rays sets up potentials in the thermocouples which remain isolated until the circuit to earth is completed by the scanning beam and the resistance R<SP>1</SP>. In making the target the temporary support B, which is preferably of cellulose acetate, is first formed by forming a solution of the acetate in water and lowering the water level so that a film is formed on frame F<SP>1</SP>. When this film is dry the plate P is formed on B, for instance by evaporating in vacuo a film of gold, platinum or other non-oxidisable metal. A half-tone screen is then placed over P and the two layers Bi, Sb of different metals are deposited through the interstices of the mesh. The metals are preferably bismuth and antimony, but platinum, lead, tin, copper, gold, silver, zinc, or iron may be used. The mesh is removed and a second frame F<SP>2</SP> fitted over the bottom frame F<SP>1</SP> and clamped to it. The Specification as open to inspection under Sect. 91 illustrates the temporary support B in position in the tube as in Fig. 1, but actually it is removed before the target is placed in the tube, for example by dissolving it in amyl acetate.
