[Class 52 (v)] [Also in Groups XXV and X] A clip device for supporting articles such as pipes, miners' lamps, scaffolding members &c. on vertical prop-like supports and of the kind in which the weight of the supported article applied to one arm of a lever causes another arm to be pressed against the support has the body of the clip made in two parts 14 adapted to embrace the support and separable against spring action to allow the device to be applied laterally to the support. Fig. 6 shows the lever of simple V- form the arm 15 being provided with a hook, sling, aperture or other means not shown to receive the supported article, the other arm 19 being pressed against the support 10. This arm may be serrated or shaped as indicated in dotted lines to bite -into the support. The lever is shown mounted on a pivot pin 16 which is surrounded by the spring 17. The device may be single ended, adapted to be used with only one form of support, or as shown it may be doubleended with opposite ends 11, 13 shaped for use respectively with a flanged girder and a circular prop. Several ways of forming the lever are described, in one of which the arm 15 is horizontal to support a scaffolding member. Fig. 4 shows the lever in two parts which may be mounted on different pivots, or, as shown, on the same pivot, a projection 28 on one part engaging the edge of the other. With this form the lever arm 15 may be folded anticlockwise to lie alongside part 19 when the device is out of use. Fig. 8 shows a further form in which the lever is formed as a plate.

Title: Pressure vessel
Inventor: GREER EDWARD MAURICE
IPC: F15B1/16
Filed: 1962-01-12
Abstract: 930,900. Hydraulic accumulators. GREER HYDRAULICS Inc. Jan. 12, 1962, No. 1270/62. Class 69 (2). An hydraulic accumulator comprises an elongated container having an axial port 57, a curved end wall 13 and a substantially cylindrical side wall 12, a deformable bladder 45 having a mouth with a thickened rim 47, a flexible clamp plate 48 having an annular recess 51 for receiving the thickened rim and an opening 57 aligned with the axial port, and means 55 extending through the opening and port to secure the clamp plate against the end wall adjacent the port. The bladder when undistended is of less length than the container and a portion 65 of its wall adjacent the rim 47 is thicker than the remainder of the wall and engages a bent part 52 of the clamp plate and the junction of the end wall 13 and side wall 12 of the container. The means securing the plate to the container consists of a plug 55 which may be welded to the plate and is retained in position by a nut 61, a port 62 and valve 63 being provided in the plug for supplying gas to the accumulator. The cylindrical wall 12 of the container is welded to an end member 14 in which is a valve 22 for hydraulic fluid comprising a member 35 urged to a position opening ports 37 by a spring 43. The accumulator is assembled by first engaging the rim 47 on the recess 51 of the plate and securing the plate to the end wall 13 by the nut 61 and then welding the end member 14 to the wall 12. Gas is thereafter supplied through the valve 63 to the bladder which is extended to fill the container and press the clamp plate 48 into engagement with the end wall, the rim 47 of the bladder being deformed as shown in Fig. 2. When hydraulic fluid is supplied through the valve 22, the gas and bladder are compressed but because the region between the plate 48 and end wall 13 is at a lower pressure than the gas and liquid, the plate 48 is retained against the end wall to maintain the rim securely clamped. The thickened portion 65 of the bladder ensures that extension of the bladder occurs mainly in the less thick portion and reduces the tendency for the rim 47 being pulled from between the clamp plate and end wall.

Filed: 1929-01-16
Abstract: 326,921. Smith, C. S. Jan. 16, 1929. Controlling different functions by same lever; relay or power apparatus.-The magnet coil 3 on the driving-member of an electromagnetic friction clutch 4, 12 for road or rail vehicles &c. is energized from a generator 5, driven by the prime mover (not shown), when an adjustable switch 2 is allowed to close by depression of the throttle-pedal 1. The clutch becomes engaged only when the engines-speed is sufficiently high, and, if the clutch is designed to dissipate heat, the change-speed gear may be eliminated, the clutch slipping when the engine-speed is reduced by overload. A manual switch 8, coacting with a contact 9, may be placed in parallel with the switch 2 and, in the form shown, the switch 8 coacts also with a variable resistance 10 to switch in a storage battery 6, there being provided a cut-out 7 comprising series and shunt windings and a circuit-breaker to prevent current reversal. The battery is used to engage the clutch when the engine-starter acts therethrough, when re-engaging the clutch after coasting in order to turn the engine, and when it is desired to use the switched-off engine as a brake. Modifications are described in which no battery is provided, the switch 8 merely acting to short-circuit the switch 2 when the engine is to be used as a brake with the pedal 1 released. In one form, Fig. 2, (not shown), one pole of the generator 5 and one end of the coil 3 are " earthed " to the chassis &c., and in another form, Fig. 3 (not shown), the switches 2, 8 are arranged in the shunt field circuit of the generator. The Provisional Specification describes the driven member of the clutch as the excited member, and states that the coils may be energized from the external source.

IPC: B01D25/32
Filed: 1926-01-20
Abstract: 268,474. Alexander, H. M. Jan. 20, 1926. Filtering-media; filters having sheet filtering- materials.-Filtering-media, such as felt, paper or textile fabric, charged with oils or fats are cleansed by forcing therethrough a solvent for oils or fats which is of greater specific gravity than water, has a lower boiling point and specific heat than the oil or fat and is substantially non- inflammable. Halogen derivatives of hydrocarbons, particularly trichlorethylene, carbon tetrachloride, tetrachlorethane and dichlorethylene, are suitable solvents. The solvent is afterwards separated from the fat by distillation. The method can be applied to a filter having tubular elements without dismantling- the elements and without emptying the filter. Air or steam may be passed through the elements both before and after the solvent is passed, in the first case to loosen and partiallv remove the oil or fat and in the second case to remove any solvent retained by the filtering-medium.

Filed: 1973-01-12
Abstract: 1409372 Coated articles HOECHST AG 12 Jan 1973 [15 Jan 1972] 1832/73 Heading B2E [Also in Division B8] A shaped article of a light-degradable plastics material, has on at least one surface a layer capable of absorbing light of any wavelength which can degrade the plastics material, the layer being capable of being detached, or dissolved under the action of water. The plastics material may be inherently light-degradable or it may have been sensitised by incorporation of sensitisers. Suitable light-degradable plastics that are specified are sensitised polyethylene, polypropylene, polystyrene, and copolymers such as butadiene/acrylonitrile/styrene copolymers, polyacetals, polyesters, cellulose esters and halogen-containing polymers such as polyvinyl chloride. The article may be in the form of sheets, films and filaments. The absorbants may be non-transparent substances such as carbon black, clay, rock dust, chalk, iron oxide, titanium dioxide and metal bronzes. If a transparent layer is desired known UV absorbants can be employed such as the hydroxy-benzophenones and hydroxybenztriazoles. The absorbing substance may be applied as a film and suitable film-forming agents are dispersions such as are polyvinyl esters, polyethers or polyacetals, e.g. a copolymer of trioxane with 80% by weight or dioxolane. Polyvinylmethyl ethers, and cellulose ethers such as methyl, dihydroxyethyl or carboxymethyl cellulose may also be used. Wholly or partially hydrolised polyvinyl acetate having a residual acetyl content of less than 25% may also be used and films of polymers which are not directly soluble in water such as polyvinyl acetate may also be employed after having been rendered sensitive to the action of water by adding readily water-soluble polymers such as polyvinyl alcohol or polyacrylamide. Polyamides such as poly-D-glutamic acid methyl ester can be rendered watersoluble also. The thickness of the absorbant protected layer can vary and is generally of 10 to 1000 microns.
