Title: Apparatus for forming strips into batches
Inventor: STUBBINS DEREK
IPC: B65G17/46
Filed: 1966-09-23
Abstract: 1,185,981. Stacking apparatus; conveyers. DAVY & UNITED ENG. CO. Ltd. 22 Sep t ., 1967 [23 Sept., 1966], No. 42536/66. Headings B8A and B8C. A device for stacking hot steel strip into batches for annealing purposes comprises a pivotable arm having movable along it a stop. The arm receives the strips while inclined to the vertical, the strips building up one at the time against the stop which descends as the stack accumulates. The arm then pivots down with the completed stack to deposit it on a conveyer for slow transit during which cooling occurs. Stacking and conveying.-Rotary members 13 sweep the incoming strips, travelling in the direction of their length transversely onto an incline 60, 61, the lower portion 61 of which is pivotable about a shaft 63 to adjust the gap between its lower edge and the surface of the arm. Similar members 13<SP>1</SP> sweep off material in a direction away from the arm. The latter comprises supports 38 spaced along a shaft 32, bars 47 forming the stop and being slidable along the supports by hydraulic devices. The gap between the incline and shaft is just sufficient to enable strips to fall onto the bars 47 which descend progressively. Hydraulic means 53 lowers the supports, when a stack is complete, until the stack rests on plates 19 on a spaced series of conveyer chains 30. Dogs 15 pick up the stack 29 which is moved intermittently up an incline. Unstacking and restocking.-At the peak of the incline, the strips slip one by one down a slope 16 onto a shuffle-bar arrangement 17 (not detailed). They are moved transversely to their length onto one of two halves of a roller-table 18, a layer being formed on the first half and then stops 29 rising so that a layer is formed on the second. The two layers so formed are fed lengthwise by the rollers simultaneously to shears extending across the full width of both layers (not shown). The double width layers of sheared lengths are fed, still lengthwise, by opposed rollers onto one half of a moveable stacking table, Figs. 4-6 (not shown). As each layer is deposited, so the table half descends until a desired stack is formed. The table then moves transversely to the length of the strips to present its other half to the incoming layers to form a second stack. The stacks may be raised for removal by jacks on the table (not detailed) or by a crane etc.

Abstract: 1,021,983. Nozzles. C. E. J. NYBERG. Oct. 19, 1964 [Oct. 17, 1963], No. 42588/64. Heading B2F. [Also in Division F2] A pressure fluid blow pistol with a fluid inlet 3 and an outlet pipe 1 is operated by a spring- loaded handle 10, a projection 12 of which acts eccentrically upon the enlarged head 13a of a plunger 13 causing an elastic diaphragm 8 to move into and out of contact with a parted seat 7. An annular chamber 6, coaxial with said seat is connected to the inlet whilst the port in the seat is connected to the outlet. On moving the handle against its spring 11, the plunger is released and the fluid acting on the diaphragm in chamber 6 causes the diaphragm to be depressed to permit fluid flow. Since the plunger 13 is a loose fit in its sleeve 9, due to the eccentric action of the projection 12, the plunger is tilted slightly relative to the sleeve, causing the port in the seat to be initially open diametrically opposite the projection 12.

Abstract: 1,099,310. Selecting records. NATIONAL CASH REGISTER CO. Sept. 27, 1966 [Nov. 5, 1965], No. 42993/66. Heading G4M. In a card random access memory of the type disclosed in Specification 889,788, the gating rods 20, which normally engage notches in the sides of the strips suspended in the magazine, are provided with a damping device to reduce the force of impact on the notches when the gating rods are returned from the disengaged to the engaged position.

When solenoids 51 are de-energized, springs 48 return racks 47 and rods 20 towards the engaging position, the initial movement being rapid, but since racks 47 are coupled to dashpots 56, the speed of movement is greatly diminished by the time the rods 20 engage the retaining notches in the strips. The dashpots 56 comprise a cylinder 57 having a small aperture 58 and a piston 59 coupled to racks 47 by a rod 61 and a bracket 62. A partial vacuum is formed in cylinder 57 as piston 59 is moved downwards on return of the rods 20 to the engaging position.

Abstract: 1474836 Rotary heat exchanger UNICE MACHINE CO 24 Oct 1975 [25 Oct 1974] 43928/75 Heading F4S A heat exchanger (e.g. for crystallization processing of sugar massecuites) comprises tubing fixed on a shaft 17 which rotates in a container 16. The tubing forms sectors A-D of circles. The tubing of each sector comprises two hollow arms 30, Fig. 2, joined by arcuate portions 31, 32, 33 with flow through the tubing being as indicated in section A by arrows. Each such sector of tubing is named an element. As shown in Fig. 2, four elements form a planar set of elements. As shown in Fig. 1, there are fifteen sets of elements 1-15. The elements of adjacent sets of elements are connected by channels 34. Cold water flows through inlet 42, Fig. 1, into the end of hollow shaft 17 and then through holes 35, Fig. 2, (the shaft being blocked at 36) to the elements of the first set of elements and thence is transmitted by the channels 34 to the second set of elements. The water passes from the element in sector A of set 1 (namely element Al) to the element in sector B of set 2 (namely element B2). It then passes in sequence through elements C3, D4 &c. to C15. This forms one water conduit. Another conduit is through elements B1, C2, D3 &c. Other conduits are through elements C1, D2 &c. and through elements D1, A2 &c. From the last set of elements 15, the water passes into the other end of the hollow shaft 17 and thence through outlet 43. While the cooling water passes through the elements, the sugar massecuites to be cooled passes from an inlet (not shown) at the right hand side of Fig. 1 to an overflow and outlet channel 47. The member built up from the shaft 17 and elements has paddles 48 and is rotated in the direction of arrow 46. The apparatus has flanges 26 whereby a part of each element can be detached for repair. Arrangements could be made for supplying hot (instead of cold) water to part of the elements for reheating purposes when required.

Preferably the particles are themselves made of or coated with the metal e.g. on a refractory core. The rotating drum may be either immersed in Fig. 1 or itself hold the electrolyte (Fig. 2) within which is arranged at least one anode 4. Electrolyte may be removed, preferably via a hollow and perforated anode 4 (Fig. 2), from the anode region for treatment and regeneration via tubes 5, pH control unit 6, pump 7, filter 8 and heat exchanger 9, to return via tube 9A. For example, the drum may be charged with carbonyl Ni shperes and the bath filled with electrolyte comprising NiSO 4 , Na 2 SO 4  and H 3 BO 3 , or with Cu grain and pieces of cut Cu wire, (Fig. 2) with electrolyte comprising CuSO 4  and H 2 SO 4 . The anode(s) may be of the metal being deposited e.g. Ni or inert, e.g. Pb or Pt coated Ti. The bodies produced may be discharged automatically, e.g. by inclining the drum, to roll through sorting, washing and drying stations, finally being stored in a hopper for automatic weighing and bagging. The drum may include internal vanes to assist in the agitation.
