Abstract: 569,145. Fluid-pressure servomotorcontrol systems. LIVERPOOL BORAX CO., Ltd., BANNISTER, H. W., and PARKER, E. B. Aug. 26, 1943, No. 13901. [Class 135] [Also in Group XXVIII] For cleaning a pipe system, particularly for conveying liquids having solids in suspension, a valve controlling the supply of flushing liquid to the system is automatically operated on cessation of flow of liquid in the system. Means for cutting off the flushing liquid auto - matically after a predetermined time are provided. A flow detector 2 may be a vane within the pipe-line actuating a switch of the kind known under the Registered Trade Mark " Mercoid " in the circuit of a motor 8 operating a valve in the fiushing liquid supply pipe 4, connected through a check valve 6 to the pipe-line. The timing device may comprise a float 10 in a chamber 11 which drains at a slower rate than it is supplied from the branch 12 of the supply pipe 4, the float actuating a switch 9 to cause the motor to close the valve. The operating time is controlled by adjusting a valve 13. In another arrangement, an electromagnetic valve is energized in response to the flow-detector, at the same time starting a small motor geared to a cam adapted to break the valve circuit and close the valve when desired. In a further arrangement, the flow-detector controls the admission of compressed air to a diaphragm-operated supply valve and the timing device comprises a meter in the supply pipe arranged to reduce the pressure acting on the diaphragm after a given quantity of flushing liquid has been discharged into the pipe-line.

Title: Improvements in or relating to insecticidal compositions
Inventor: GEROLT PHILIP
IPC: A01N25/08
Filed: 1956-05-07
Abstract: Insecticidal compositions comprise aldrin, dieldrin, endrin or isodrin in intimate contact with a solid solvent, i.e. a solid substance which (1) in bulk or in particulate form will dissolve at least part of the insecticidal substance in contact therewith, or (2) will form a solid solution of the insecticidal substance on cooling a molten mixture of the solid substance and the insecticidal substance or (3) will form a solid solution of the insecticidal substance on removing the liquid solvent from a mixture of the two components in solution.  Preferably, the solid solvent is a hard, brittle grindable substance preferably having no definite crystal lattice and can be liquefied by heat, suitably at a temperature in the range 50 DEG  to 250 DEG  C.  Specified solid solvents are the naturally occurring resins such as colophony, wood rosins, copal, dammar and kauri gum, synthetic resins such as phenol aldehyde resins, particularly the phenol formaldehyde resins known as resols and novolaks, alkyd resins such as those derived by condensation of maleic anhydride and rosin, the glyceryl phthalate resins and pentaerythrityl resins, oxidized rosins, coumarone and coumaroneindene resins, petroleum resins solid polychlorinated polyphenyls, sulphur, asphaltic bitumens, petroleum and coal tar pitches and naturally occurring asphaltites.  Intimate contact between the insecticidal substance and the solid solvent is obtained by milling together the insecticide and solid solvent or by evaporating to dryness a solution of the two components in a mutual organic solvent and comminuting the solid residue or by spray drying the solution. Other insecticidal, acaricidal and bactericidal compounds may be incorporated.  Specification 772,193 is referred to.

Title: Improvements in push-pull switches
IPC: H01H15/02
Filed: 1943-08-31
Abstract: 564,887. Retractive switches. ARROW ELECTRIC SWITCHES, Ltd. Aug. 31, 1943, No. 14173. Convention date, April 9, 1943. [Class 38 (v)] In a switch of the kind in which a movable bridging contact 34 slidable on the stem 18 of a manuallyoperable plunger 14, can be raised or lowered to engage contacts 42 or 44 by pulley or pushing the plunger, the intermediate position is maintained by a pair of springs, of which one, 24, bearing on a washer.26, urges the plunger upwards, while the other, 32, bearing on a part 28 of the base, urges the contact downwards. The latter movement is resisted by a further spring 46 bearing on washers fixed to the stem-foot and on a sleeve 54 slidable on the stem 18 and bearing on the contact 34. When the plunger is pushed, spring 24 is compressed and spring 32 expands and presses 34 against contacts 44. When released, the plunger is restored by spring 24 and a sleeve 30 slidable on stem 18 is urged by contact 34 to abut on washer 26 and prevent overshooting of the contact 34. When the plunger is pulled, spring 32 is compressed by the force transmitted to contact 34 through the spring 46, which, however, accommodates excessive upward movement of the plunger and serves as an indication to the operator.

Filed: 1928-05-15
Abstract: 290,671. Soc. d'Expansion Technique. May 19, 1927, [Convention date]. Centrifugal machines. -A plurality of vertical rotating moulds 1, each with its electric motor 10, is carried by a turret 2 intermittently rotated by a motor 55 and driving-wheel 58. The molten material is supplied from a pot 48 by a valve 50 and tilting trough 46 which in one position supplies good material to the mould and in the other discharges cold or dirty material into a receiver 52. The material falls through a funnel 44 into a rotating deflector 15 arranged in the top of a rotating mould, the deflector falling gradually to the bottom under control of an hydraulic cylinder 26 and valve 39, during casting. The movements of the deflector and mould are started by controls actuated by the tilting of the trough 46 and when the deflector reaches its lowest position, shown in Fig. 1, it actuates switches to stop the motors rotating the mould and deflector and to start the motor 55 thus rotating the turret 2 to bring the next mould 1<a>, Fig. 3, into casting-position and the charged mould 1 into position for lowering the casting C away by a support 63 after the socketcore 61, Fig. 1, has been removed by hand. The empty mould 1<b>, Fig. 3, is cooled by a water spray 65 or by a current of air. The moulds are supported nad rotated by friction or toothed wheels 4, 5, Fig. 1, and are also supported by rollers 11 which can be interchanged to allow different sized moulds to be used.
