Abstract: 191,259. Smith, A. H. Dec. 12, 1921. Vehicles with removable bodies.-Relates to railway vehicles adapted to carry a number of receptacles for transporting goods without re-packing. The receptacles 13 are arranged in a lower series supported directly on the truck or vehicle body 2 and an upper series which is superposed on the first series and releasably locked thereto, whereby a lower and a superposed receptacle may be removed as a unit. The connecting means between an upper and lower receptacle preferably consists of a sliding bolt 22 and staple 23 on the upper receptacle co-operating with a hinged hasp 24 on the lower receptacle. The lower receptacle is positioned in the truck by means of projections 7 on the receptacle engaging guide-ways 5, Fig. 2, on the sides of the truck, which are also provided with supports 8 for preventing flexing of the central portions of the receptacles. The side-walls of the truck prevent opening of the doors of the lower receptacles during transit, while stops 16 on the doors of the receptacles engaging abutments 17 on the upper edges of the lower receptacles prevent opening of the doors of the upper receptacles. The walls of the receptacles are extended at 26 below the floor 25, for which supports 27 are provided on the tops of the lower receptacles. Gusset plates 10 with perforations 11 serve for attaching the chains of a crane.

Abstract: 1,115,856. Control systems for arc welding. SOCIETE INDUSTRIELLE DE COMBUSTIBLE NUCLEAIRE. 27 July, 1966 [28 July, 1965], No. 33724/66. Heading H2H. [Also in Division B3] In inert gas shielded non-consumable electrode arc welding, a seam is welded in two passes, the first using A.C. and the second using D.C. electrode negative. During the first 390 degrees of rotation of the work 27 by a motor 30, the welding torch 25 is supplied with A.C. from transformer 1. The motor 30 drives cams 35, 36, 37 at a third of the rotary speed of the work 27. Cam 37 increases the speed of the motor 30 during the first 500 degrees of rotation of the work 27 and then keeps it constant. When the work has rotated 390 degrees, cam 36 operates a switch 20 . . . 22 to connect rectifier 11 in the welding circuit to supply D.C. to the torch 25. After 780 degrees, cam 35 controls a motorized rheostat 10 to regulate the control current supplied to a device 5 which during the next 30 degrees reduces the welding current to 15 amps. The arc then extinguishes.

Abstract: 1,160,575. Nets. UNION CARBIDE CORP. 31 Aug., 1966, No. 38810/66. Heading D1R. A self-supporting network is formed by looping a plurality of strands 26, 27 alternately onto advancing support members 32 and 34, e.g. upstanding pins mounted on chain 33, to form a criss-cross network 33, supplying a plurality of extra adhesive strands 64, 65, 66 into contact with the non-adhesive strands and between the crossing points thereof and bonding the strands together. The extra adhesive strands 64, 65, 66 can be (a) supplied longitudinally on at least one face of the network, as shown, (b) in a common plane between the sets of parallel strands, see Figs. 2 and 8, not shown or (c) longitudinally on each side of the network but with the adhesive strands being laterally offset from each other see Figs: 7, 9 and 10 not shown. The adhesive strands can be coated or impregnated with a latex, emulsion solution or melt of polyester, epoxy resin, phenolic resin, silicone, acrylic resin, melamine resin, polymer or copolymer of vinyl chloride, e.g. copolymer with vinyl acetate or vinylidene chloride, polystyrene polyamide, polycarbonate, styrene-acrylonitrile copolymer or chloro- or fluoro-carbon or rubbery resins. The criss-crossed strands 26, 27 can be cotton, nylon or fibreglass. The strands can be pressed prior to setting the adhesive e.g. with rollers (29, 62, 143) see Figs. 63 and 5, not shown. The adhesive strands can be aligned by a grooved roller (76), see Fig. 1, or a comb or reed. The net can be spread as described in Specification 1112561. The mesh size of the network can 'be reduced; in the embodiment shown this is achieved by releasing the looped strands from the pins 34 and resecuring it using two sets of gripping discs and 'bands onto drum 93 with gripping bands 94, 95, 98 and 99 which pinch the network with the looped edges bent at right angles. The drum 93 can also be heated.

Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] In a rotary switch, the rotatable contactcarrying member carries a polygonal, e.g. a square-sectioned member 26 the sides of which are embraced by two jaws 27, 28 which are pressed towards each other by the two ends of an open spring 40, thereby determining the positions of the switch. The other ends of the jaws 27, 28 bear against opposite sides of a vertical support 35. The member 26 may, as shown, be U-shaped and the legs of the U may pass through a square hole in a cup 63 which rotates in a hole in a horizontallydisposed portion of the support 35. The legs of the U also guide the spindle 12 which is rotated by a handle (not shown). An additional quick-action may be given to the switch by a spring 19 mounted in two drums 20, 20a fixed respectively to the spindle 12 and the member 26. When the spindle 12 is rotated, the drum 20 moves with it and carries round one end of the spring 19, which is thereby strained. The other end of the spring 19 bears on the drum 20a and tries to rotate it and with it the member 26 and the contact member, but movement is prevented till the spring is sufficiently strained to force the member 26 round against the opposition of the spring-pressed jaws 27, 28.

A fluid control valve, Fig. 1 (not shown), for a brake mechanism in winding equipment, comprises an operating spindle (3) secured in a resilient bush (11) of bonded rubber by a seal (10) which is capable of being deformed in response to longitudinal movement of the spindle. The spindle (3) is mounted in the bush (11), and the bush (11) in the valve casing (2) by a further seal (9). In Fig. 1 the spindle (3) moves a valve member which is associated with the seat (5) to control fluid passing through the inlet (6) and outlet (7). In Fig. 2, (not shown,) the spindle (19) is operatively connected to a load-cell (12) having a pressure chamber (17) and low-pressure inlet (18) for a control fluid, preferably controlled by a valve similar to Fig. 1, to move the spindle against the action of a pre-set spring (22). The load-cell is mounted in a resilient bush (15) which can be pre-stressed to remove the need for a spring (22). A further embodiment describes a plurality of springs disposed on a pitch circle diameter around the spindle (19). Further embodiments describe a system of levers for actuating the valve of Fig. 1, comprising a hand or foot lever having a resiliently mounted cam to move a further lever operatively associated with the spindle (3).

As shown the adjustment of the metering opening width is achieved by adjustment of the relative axial positions of a frusto conical end plate 90 secured to the shaft and a ring-shaped member 96 secured to the housing. The intake end of the shaft 66 is mounted by a bearing assembly 58 in a hub portion 56 threadably engaged in the housing 14. Movement of arms 106 rotates the hub portion 56 to cause the plate 90 to be axially moved relative to the member 96.

The soy bean material is supplied to the intake opening 20 by a hopper (22), Fig. 1 (not shown), fed by an auger (24). The rate of rotation of the auger (24) is controlled by using a valve (28), Fig. 6 (not shown), to control the amount of fluid supplied to a hydraulic motor (26) driving the auger. The machine (10), Fig. 1 (not shown), includes a frame (12) having wheels and is intended to be pulled by a tractor. The shaft 66 is connected to the tractor power take-off shaft (84).
