Abstract: Foamed or foamable vinyl-aromatic polymer resin compositions comprise a compound which exhibits a visible fluorescence under the influence of ultra-violet light.  These compositions are preferably made by polymerizing an aqueous emulsion of a vinyl-aromatic monomer, a blowing agent, the ultra-violet flourescent substance and optionally other additives such as flame retarding agents.  Polymerization catalysts such as dibenzoyl peroxide and emulsifiers such as polyvinyl-pyrrolidone may also be present in the emulsion.  According to an alternative embodiment of the invention the foamable resin composition may be obtained by coating particles of a foamable vinyl-aromatic resin with a surface layer which comprises the additives.  The preferred vinyl-aromatic resin is a styrene polymer. Homo-polymers of chlorostyrene, vinyl-toluene or a -methyl-styrene as well as copolymers of a vinyl-aromatic monomer with acrylonitrile, vinyl-chloride, vinyl-acetate, methyl acrylate, methyl methacrylate or ethyl acrylate may be used.  The ultra-violet fluorescent compound, which is preferably soluble in the vinyl-aromatic monomer, may be a derivative of 4,41-bis(triazinyl)-stilbene -2,21-di-sulphonic acid, 2,5-(di-benzimidazol - 21 - yl) - furan, a ,b  - di - (aryloxazol - 2 - yl) - ethylene or 2,5 - di - (benzoxazol - 21 - yl) - thiophene -particularly suitable is " Uvitex " (Registered Trade Mark) which is stated to be 2,5 - di - (41,51 - dimethyl - benzoxazol - 21 - yl) - 3,4 -dimethyl-thiophene and is added in a proportion amounting to 0.0001 to 0.1% by weight of the polymer.

Filed: 1974-12-03
Abstract: 1492566 Gripping tines A T VAN HUET 3 Dec 1974 52220/74 Heading B8H A loading fork for use in lifting articles such as stacks of bricks comprises a frame 1 for attachment to hoisting equipment such as the overhead trolley of a crane (not shown), a plurality of prongs 18 extending from the bottom of the frame 1 for engagement in gaps formed in the bottom layer of bricks of a stack, each prong 18 including spring gripping members which are laterally movable relative to the prong for gripping the bricks between themselves and the closed side of the adjacent prong. The prongs 18 are adjustably and detachably secured to a beam 15 which is mounted on a lower support member 3 of the frame 1, each prong 18 have a fastening plate 17 attached thereto which receives bolts (17d) which extend upwardly through a slot (16) in beam 15 and are fastened to a displaceable plate (17b) located in the beam 15, Fig. 4 (not shown). The spring gripping members comprise deformable leaf spring members 21, Fig. 5, mounted on a spring support 20, each such support 20 being movable transversely of its prong 18 from its retracted position of Fig. 5 to its extended operative position, Fig. 6 (not shown), by means of a shaft 27, the latter being movable in bearings 25 to effect movement of the spring supports 20. The leaf spring members 21 are releasably attached by means of screws 23 to the associated spring support 20, each spring support 20 being releasably attached to a connecting piece 30 which in turn is releasably attached to the shaft 27. In Fig. 5 four leaf spring members 21 are shown to be associated with each prong 18 but each prong may have just one leaf spring member associated therewith. In use of the loading fork, after the prongs 18 have been inserted into gaps formed in the lower layer of a stack of bricks to be lifted, the hoisting equipment which is connected to the lifting eye (105a) of a suspension mechanism 107 is operated, Fig. 2 (not shown), which causes the rotation of a beam 103 of the mechanism 107 which in turn causes upward movement of a lever 81, Fig. 1, and thus the anticlockwise rotation of a lever arrangement 54 which causes rightward movement of a lever 85 and thus the anticlockwise rotation of a lever 86 which is connected by a lever 90 to the shaft 27, so that the latter is moved leftwards in Fig. 1 to cause movement of the spring supports 20 and thus the movement of the leaf spring members 21 to their gripping positions. When the hoisting equipment again lowers the loading fork a spring 94 causes the return of the shaft 27 to its original position. The rightward movement of the lever 85 referred to above is accompanied by rightward and leftward movement of levers 91a, 91b respectively which cause side plates 50 to be moved into engagement with the sides of the stack of bricks.

Abstract: 1,200,690. Vehicle driving gear. EATON YALE & TOWNE Inc. 6 Nov., 1968 [30 Nov., 1967], No. 62684/68. Heading B7H. [Also in Division F2] In a vehicle transmission including, in the drive line of optionally driving front wheels, a double-acting one-way jamming roller clutch normally held out of engagement but automatically engaged upon a predetermined speed differential arising between the driving and driven members, e.g. when the main driving wheels slip, to give a four-wheel drive, a viscous shear fluid coupling 140 is mounted in parallel to the one-way clutch so that, when the drive line is disconnected from the prime mover for twowheel drive, the front wheels may drive the free shaft 37 through the coupling 140 without cyclic engagement/disengagement of the clutch, thus reducing the noise and wear. The coupling 140 comprises a disc (142), Fig. 6 (not shown), fast with a driven shaft 42 and extending into a narrow recess (143) in a flange 50 fast with shaft 37 and filled with silicone liquid. Although the transmitted torque is small, it is sufficient to rotate the free shaft 37, and hence prevent engagement of the clutch. As shown, the clutch comprises rollers 92 acting between an outer race 64 on the flange 50 and an inner polygonal member 76 on the shaft 42. The shaft 37 is driven by an engine (12), Fig. 1 (not shown), through a known transfer box (18), as is a shaft (21) driving the rear wheels. The rollers 92 are mounted on a cage 91 normally held by a spring arrangement 110 to prevent engagement of the clutch, the cage being moved to engage the clutch in the event of the predetermined speed differential arising. The cage has an end flange 101 extending into a recess 103 filled with the silicone liquid, the viscous shear drag of which at the predetermined speed differential overrides the spring arrangement 110 to move the cage to engage the clutch. The spring arrangement comprises four springs (115), (116), Fig. 5 (not shown), abutting seats (113), (114) on a member (111) fast with the shaft 42 and a member (112) fast with the cage 91. Again, Figs. 7 and 8 (not shown), the spring arrangement comprises a blade spring (151) riveted to the cage and having fingers (161) engaging in notches in a thrust washer (152) fast with shaft 42, relative rotation betweenthe cage and washer being opposed by the fingers which are cammed from the notches.

In a fluid container of the type in which the contents are discharged by expanding a bag within the container by fluid-pressure, the bag is arranged in a compartment, the interior of which is isolated from the interior of the container by a closure member which is arranged to be opened by the action of introducing the expanding fluid to the bag. As shown in Fig. 1 the collapsed bag 5 is housed in a compartment in the form of a piston 2 the end of the cylinder being closed by a cap 4. Fluid introduced at 3 causes the piston to displace the cap 4 and expands the bag which has a flexible pipe in its interior connected at one end to the piston 2 and having a restricted outlet at the other end so that the bag is projected into the container before expanding. In a modification, Fig. 7 (not shown), a piston 13 slidable on a rod 14 closes the end of a cylinder enclosing the collapsed bag which is attached to the piston and the end of the container so that fluid introduced into the bag forces the piston to the opposite end of the container; the bag is reinforced to ensure that this happens before it inflates. In a further modification, Fig. 8 (not shown), the bag is disposed between two pistons, initial movement of the first piston breaking sealing means around the second piston which is then forced along a guide rod to the opposite end of the container, movement of the first piston also controlling valve means for introducing fluid into the bag after the sealing means has been broken. A perforated and dimpled liner 10 is fitted inside the container.
