IPC: B22D13/10
Filed: 1919-08-22
Abstract: 138,445. Green, F. W., and Green & Son, E. Aug. 22, 1919. Flasks; moulding - machines.-In a vertical pipe mould in which the bulb J for pressing the sand B in the flask A is guided in its upward movement by a central stem F, which may be detachably secured to the flask A by a conical collar D and cotter pin H, the bulb J is raised by a tubular stem K surrounding the stem F and having a hole L for attaching a rope or chain.

Title: Improvements in or relating to circular looms
Inventor: LOW ROBERT NORRIE
IPC: D03D37/00
Filed: 1952-02-22
Abstract: 718,447. Shuttles for circular looms. FAIRWEST (U.K.), Ltd. Feb. 23. 1953 [Feb. 22, 1952], No. 4721/52. Class 142(2) A shuttle carries an additional weft that is laid when the normal weft fails and until the shuttle comes to rest upon operation of a weft stop-motion. The additional weft g is laid by a needle f carried by a block e sliding on two rods d on the end of the shuttle stem. In one construction, the needle f and the block e are normally held in a retracted position by a latch that engages a projection h on the block. Upon weft failure, a centrifugal switch r causes the loom to stop and an electromagnet k is energized. The latch j is thereby withdrawn and the pressure of the warp on the block causes the block to slide along the rods d and the needle f to lay the additional weft in the crossing warp threads. In an alternative construction, the needle m is connected to an armature n of an electromagnet p fxed to the rods d. When the electromagnet is energized, upon weft falure, the armature is moved against a spring q and the needle is projected into the closing warp threads. The centrifugal switch may be as described in Specification 716,717.

Syrup overflowing from the cans &c. during filling falls through a screen 9 into a tank 7. In the construction shown in Fig. 8 the conveyer is totally disposed above the tank 7 and screen 9, so that the screen can be removed without disturbing the conveyer.

Title: Improvements in or relating to electric water heaters or geysers
IPC: F24H9/20
Filed: 1926-02-20
Abstract: 269,704. Benham & Sons, Ltd., and Hicks, C. E. Feb. 20, 1926. Heating by electricity.- In an electric water heater the water supply is controlled by a disc valve g so connected to the switch b that when the valve is open the switch is closed and conversely, and a second valve is also provided whereby the supply of water can be controlled but not entirely cut off. For this purpose the valve g is operated by a lever d connected to the switch by a link e and in the supply pipe a is arranged a plug-cock on the spindle i of which are a handle k and arms l. When the valve g is opened the cock can be closed to an amount determined by an adjustable stop m on the lever d against which the arm l strikes, the arm n preventing closing of the cock by turning in the other direction. When the valve g is closed the stop m strikes against the arm l and opens the cock fully so that the supply is always fully turned on when the switch is first closed.

Abstract: 398,802. Supply and control systems for consuming-devices ; rectifying alternating current. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. - (Assignees of Morack, M. M. ; 900, Union Street, Schenectady, New York, U.S.A.) Feb. 19, 1932, No. 5027. Convention date, Feb. 19, 1931. [Classes 38 (ii) and 38 (iv).] An arrangement for generating low-frequency intermittent current impulses comprises a three electrode discharge tube, which may be of the vapour type, the anode of which is supplied with A.C. in series with a load 11, the control grid being connected to a resistance-capacity discharge system supplied from a battery 17 for periodically rendering the grid positive so that the valve conducts. The grid is normally biased negatively by a battery 16 through resistances 15, 14 and the condenser charging circuit 17, 18, 19, 15 is such that the charging current of the condenser 18 applies a P.D. on the resistance 15 which opposes that of the battery 16 and reduces the negative bias on.the grid. When the condenser is charged to a predetermined voltage it is discharged through a glow discharge tube 21 and variable resistance 20. The negative grid bias is only reduced appreciably during the early stages of the condenser charging when the P.D. across the resistance 15 is sufficiently large. The duration and 'frequency of the current impulses in the load circuit is determined by the values of the condenser 18 and resistances 19, 20. The device may be used in flashing electric lights for sign lighting, traffic beacon flashing, &c.

[Class 40 (v).] An oscillation generator for producing alternating current of rectangular wave form comprises two relaxation oscillation circuits I, II fed from tapped portions of a battery 5, these circuits including resistances 8, 12 which are in the circuit of an additional discharge device 14. The voltage applied to the device 14 from the battery 5 is intermediate its ignition and extinction voltages and the resistances 8, 12 are of such a value that current impulses in the circuits I, II respectively raise the voltage across the device 14 above its ignition voltage and lower it below its extinction voltage, so that the device 14 is rendered periodically conducting and non-conducting. The circuits I, II are maintained in synchronism by means of an A.C. control voltage which is applied to the electrodes 15, 16 of the devices 9, 13 through phase-shifting means. By adjusting the phase of the current impulses in the circuits I, II the period of conduction of the device 14 can be varied.
