Title: Process for Producing Composite Metal Article
IPC: B23K20/04
Filed: 1967-05-05
Abstract: 1,176,563. Making composite strip; jointing by rolling. OLIN MATHIESON CHEMICAL CORP. 5 May, 1967 [11 May, 1966], No. 21051/67. Headings B3A and B3M. A composite article comprising a core clad with a dissimilar metal is made by rolling together the core and the cladding to form a green-bond therebetween, i.e. a bond which requires a peeling force of less than 40 pounds for a ¥ in. width strip to separate the layers, and thereafter cold rolling the composite to effect a reduction at least 5% in excess of the reduction which produces the maximum hardness of the core. The core material is preferably copper, iron or aluminium or base alloys thereof many of which are named. In the case of a copper core a reduction of 60-78% produces the green bond and an additional coldrolling reduction of at least 18% is necessary to give a total reduction of 75% and produce a strong bond. In a preferred example a copper alloy containing 99À9% copper was clad with a copper base alloy containing 75% copper and 25% nickel. The core is cleaned in alkaline detergent, e.g. carbon tetrachloride or trichloroethylene, and dried and the surface of the core and cladding abraded. The initial rolling is between rolls with a speed in excess of 20 ft./  min., e.g. 40-150 ft./min. The reduction after one pass is 70% and the cladding is arranged so that it first contacts the core in the nip of the rolls by arranging an angle between the core and the claddings of 5 to 22 degrees, preferably 6 degrees. The copper composite is subsequently cold-rolled with a reduction of 5% greater than the reduction which produces maximum hardness of the core, i.e. 20% in the Figure. In aluminium and iron core composites the initial reduction is 40-65%. The cladding material may be any material dissimilar to the core, i.e. a material having different physical properties such as grain size. Examples are high purity tin, copper, lead, nickel, zinc, iron, silver, aluminium or base alloys of these materials. A large number of typical alloying materials are given. The core material should be less than ¢ inch thick and the cladding less than “ inch thick. The lowest gauge being about 0À001 inch. The core may be clad on one or both sides.

Abstract: 480,303. Coin freed article - delivery apparatus. PARNALL & SONS, Ltd. (Wistoft, S.) July 31, 1937, No. 21276. [Class 27] In a coin-freed vending-machine in which a number of compartments or drawers are all released by the insertion of a coin, the opening of a selected drawer or compartment causing all the others to be locked, each drawer or compartment is associated with a control member 2, pivoted at 1 and having a pin 3 engaging a slot 4 in the drawer so that when the drawer is pulled out the corresponding member 2 is rotated clockwise. Each member 2 has an open-ended slot 6 operating in conjunction with a pin 8 on a rail 7 common to all the drawers and freed for movement by the insertion of a coin. When a selected drawer 5 is pulled out, in its first movement a face 2a on the member 2 is moved up against the corresponding pin 8 of the rail 7 which is moved to the right by the face 2a and then a curved surface 2b acts on the pin 8. During the first movement of the drawer, a pin 9 on the member 2 passes between a pair of a series of plates 10 slidable in pins 1, 12. The plates can move just sufficiently to allow one pin 9 to pass so that all the other drawers are locked against movement. When the pin 9 has passed through and released the plates 10, the rail 7 has been moved so far that the remaining pins 8 thereon have moved along the slots 6 other control members 2 and locked the corresponding drawers. The members 2 have curved toothed portions 13a co-operating with spring-controlled pawls 14 to ensure a full stroke of the selected drawer at each actuation.

Title: Improvements in and relating to apparatus for chlorinating water

Filed: 1943-12-20
Abstract: 577,582. Chlorinating water. BELL, N. M., and CHILDS, W. C. Dec. 20, 1943, Nos. 21334/43 and 12178/44. Addition to 551,634. [Class 46] [Also in Group II] In a modification of the apparatus described in the parent Specification, the container 22, Fig. 4, for chlorinating solution is inverted over a vessel 12a in an outer vessel 12 into which the siphon tube 23 enters. The container 22 has a stopper provided with a tube 19 the inner end of which -is adapted to be closed by a valve 71 on a stem 70. The other end of the stem has a rubber plug 72. Before the container is to be turned from its upright position to the inverted position, the valve 71 is lifted to prevent leakage of liquid. When the container is brought into the position of use the valve is opened by the pressure on the plug 72 of the bottom of vessel 12a. Liquid discharged into this vessel flows through a small hole into the vessel 12. Flow of liquid from the container 22 ceases when liquid in vessel 12a covers the outlet from tube 19. The siphon tube 23 may be adjusted as described in the parent Specification or by any of the arrangements shown in Figs. 1, 2 and 3. The invention also comprises these arrangements for adjustment of the siphon tube, in the apparatus described in the parent Specification. As shown in Fig. 1, the siphon tube 23 is supported by arod 43 attached at one end to a counterweighted lever 40 and at the other end to a trough 44 in the water supply.tank 45. As the water fills the tank under control of a ball valve 46 a small quantity is diverted to the trough 44, whereby eventually the lever 40 is overbalanced and the rod 43 is lowered together with the siphon tube 23, so that chlorinating solution is fed therethrough to the tank 45. When the ball valve 46 closes the trough 44 empties through a small leak-hole, allowing the lever 40 to return the tube 23 to the raised position. In a modification shown in Fig. 2, the rod 43 is in two parts connected by an adjusting sleeve 43b and the lower part is connected to the arm 48 of the ball valve 46. In the arrangement shown in Fig. 3, the lever 40 is connected to a slidablymounted tube 52 closed at the lower end and carrying an outlet tube 55 which supports the siphon tube 23. Water is fed from the mains to the tube 52 by a pipe 56 and when sufficient has accumulated the lever 40 is overbalanced whereby the siphon tube is lowered and chlorinating solution is discharged therethrough. When the supply of water to pipe 56 ceases, the water in tube 52 leaks away through a hole 57 and eventually the lever 40 operates to raise the siphon tube to the inoperative position.

Abstract: 1326135 Tamper-proof closures V WASSILIEFF 19 April 1971 [11 Feb 1970] 21532/71 Heading B8T In tamper-proof plastics closure, an outer skirt 3, which is connected to a screw cap 1 or a push-on cap by frangible filaments 10, has to be removed prior to the removal of the cap. The closure is applied to a container by abutting faces 5 and 9, initial removal requiring the successive breaking of the filaments 10. In modifications, the filaments may be radially disposed, breaking simultaneously, or the projections 4, 8 may be replaced by tooth-shaped projections. Further, when a container having an external screw-thread above an external ring is used, the screw-thread of the closure may terminate at its lower end in a tapered portion thereby facilitating locking. In a further embodiment, the closure comprises a snap-on cap, axial ribs being attached to a step in the outer skirt along their upper, radial, surfaces, and to the inner skirt along their axial lengths. Closure removal requires the initial severing of the ribs along their radial surfaces allowing removal of the outer skirt. In a modification, (Fig. 9), prior to closure application the skirt 25 is rotated in the direction of the arrow S thereby placing projections 27 above projections 29, projections 28, 30 then being in contact. During push-on closure application projections 27 push on projections 29. Closure removal requires the initial removal of the skirt 25 by the severance of the filaments 31.
