Filed: 1934-11-14
Abstract: 447,282. Hydraulic transmission of power. SINCLAIR, H., 38, De Vere Gardens, Kensington, London. Nov. 14, 1934, No. 32824. [Class 69 (ii)] In an hydraulic coupling of the kinetic type, a slidable member for varying torque transmission capacity is drawn automatically into the circuit under the influence of a fluid pressure difference set up when the torque transmitted rises. As shown in Fig. 1, the member 11 disposed in a chamber 8 is carried by a hub 13 acted on by a spring 18 normally to hold it in the position shown. The chamber 8 communicates with the core space by ducts 21, 22, or ports 23, Fig. 5, are provided. A gland 7 is preferably of the diaphragm type described in Specification 400,741. In a modification, the member 11 is carried by a slidable rod 24, Fig. 2, having a pin 29 acted on by a spring 18a, the effect of the latter being varied by adjusting a collar 31. In another form, the throttling member 11b, Fig. 3, is normally accommodated in the core space and has a rib or ribs 35 engaging a guide recess or recesses 36. In a further form, the core member 20b is omitted. Specification 314,157, [Class 69 (ii)], also is referred to.

Title: Improvements in and relating to conveying apparatus
IPC: B65B35/44
Filed: 1963-08-21
Abstract: 993,998. Endless conveyers. SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT. Aug. 2 1963 [July 5, 1963], No. 33031/63. Heading B8A. Shoots 5 are maintained in alignment with a stream of biscuits 1 being fed from an endless conveyer belt 2 if the stream on the belt 2 should shift laterally for any reason. The shoots 5 are connected at their upper ends with a carriage 4 which is mounted by means of rollers 12 on a laterally disposed rail 11. The carriage 4 carries side members 16, 16. When the stream moves laterally on the belt 2, the outermost row of biscuits on one side engage the respective side member 16. A resilient clamp 15 associated with each member 16 engages the biscuits and presses them into frictional engagement with the belt. Thus the biscuits remain in position on the belt and tend to drag the carriage 4 away from its central position. The carriage 4 is re-centralized by the action of springs 21, with which a dashpot 22 is associated. The members 16 may be rigid with the carriage 4, as shown, or may be resiliently mounted thereon. The shoots 5 feed further endless conveyers 9, 10.

Title: Method for Testing Foundry Mould Materials
Inventor: HEIMGARTNER JULIUS
IPC: G01N33/38
Filed: 1967-07-19
Abstract: 1,191,699. Centrifugal casting. SULZER BROS Ltd. 19 July, 1967 [20 July, 1966], No. 33145/67. Heading B3F. In a method of testing foundry mould materials a rotatable mould 1 is formed with a cavity 2 the surface of which at least in part is formed by the material to be tested, the cavity then being filled with liquid metal and a test casting centrifugally cast to produce radially varying pressures on the cavity surface. The casting is removed from the mould and the surface of the casting is examined for signs of sintering or metal penetration. The mould 1 may be completely constructed of the foundry material (e.g. sand) to be tested and used only once; or it may be made as a two-part permanent mould, e.g. ceramic, graphite or steel, and have specimens 8 of the material to be tested inserted in the surface of the cavity 2. To produce a uniform flooding of all surfaces of the cavity the cavity may be shaped as a truncated hyperboloid, Fig. 4 (not shown), having a compensation space (13) to allow for the portion lost by truncation. The liquid metal is fed into the cavity by means of a duct (10) leading to the outer periphery of the cavity. To ascertain the effect of different pouring temperatures a number of identical moulds may be poured with the same liquid metal but at differing temperatures.

The semicircular edges of the openings 48 and the edges of the jaws between successive openings are sharpened. To gauge a wire the pliers are closed sufficiently to bring the stops 47 into abutment. To strip the wire it is inserted into the appropriate recess 48 and the pliers closed to bring the stops 47 into abutment. A gauge for measuring the length of the conductor to be stripped is provided on the other side of the tool. Circles 51 for gauging stud openings in tongues of electrical terminals are provided. In a modification, Fig. 6 (not shown), only one pair of crimping jaws is provided; the handle levers have their opposite sides lying in substantially the same plane, the wire cutter portions being bevelled from opposite sides.

Abstract: 1321497 Extruding CEFILAC 15 July 1971 [15 July 1970] 33235/71 Heading B3P In an extrusion process for rods or tubes the billet container 1 is retracted slightly away from the die 3 after extrusion so that the billet discard 8 is partially ejected from the container by the extrusion ram 5 which is kept stationary. The ram 5 is then retracted and the container 1 together with the discard 8 are retracted to allow the discard to be separated from the extrudate 7 by a circular saw (9), Fig. 4 (not shown). After separation the discard 8 is ejected by the ram 5. A viscous lubricant and a dummy block 6 may be used in the extrusion. When a mandrel 4 is used this is retracted through the stationary ram before the initial retraction of the container. The container is moved by a pair of symmetrically arranged jacks acting parallel to the press axis.

The main products are trihalovinyl alcohols of formula CX1X2=CX3-A-OH, but other products include diols of formula HO-A-CX1=CX3-A-OH, diene dehydration products of the alcohols CX1X2=CX3-A-OH, and, where the alcohol is ethanol, acetals of formula (CX1X2=CX3-A-O)2CHCH3. Temperatures from 400 to 700 DEG  C. may be used. A catalyst is optionally present, e.g. a surface active solid, noble metal, metal halide or free-radical catalyst.  An inert gaseous diluent may be present.  The products, preferably freed from hydrogen halide and unreacted starting materials, may be passed through a conventional dehydrating zone to increase the yield of dienes, or to form trienes from HO-A-CX1=CX3-A-OH. Numerous products of the types CX1X2=CX3-A-OH, HO-A-CX1=CX3-A-OH, (CX1X2=CX3-A-O-)2CHCH3 and the dienes and trienes formed by dehydration are specified and a number of the trihalovinyl alcohols are claimed per se.  The trihalovinyl alcohols may be reacted with phenyl isocyanate to give phenylurethane derivatives CX1X2=CX3-A-O-CONHC6H5\t or with O,O-dialkyl phosphoryl or thiophosphoryl chloride to give compounds of type (RO)2P(O or S)O-A-CX3=CX1X2.  Examples are given, the products being pesticides. CCl2=CCl-CH(CH3)OOCCH3 is prepared from acetychloride and 1,1,2 - trichloro - 1 - butene-3-ol.ALSO:Phenylurethanes of formulae CCl2 = CCl-CH(CH3)OCONH C6 H5 and CCl2 = CCl-C(CH3)2 OCONHC6H5 are used as pre-emergence herbicides.  Organophosphorus compounds of general formula (RO)2P(X)-OCR1 (CH3)CCl = CCl2, where R = CH3 or C2H5; R1 = H or CH3 and X = O or S, are used in aqueous dispersion to kill horseflies.
