Filed: 1938-02-10
Abstract: 510,962. Change-giving apparatus. WESTINGHOUSE TICKET MACHINE CO., Ltd., and BURNETT, W. E. Feb. 10, 1938, No. 4253. [Class 27] In an automatic changegiving machine in which change coins are delivered from the lower end of a pile in a storage tube, a movable check member, serving to detect whether there are sufficient coins for a change-giving operation, is arranged to be operatively engaged by at least two spaced coins in the pile, and is so mounted that unless thus engaged by the two or more coins is automatically moved to a position in which operation of the delivery mechanism is prevented or an indicator actuated. If one of the two or more coins remains in engagement with the check member as the rest of the pile moves downwards, the check member is still effective to prevent delivery, or actuate the indicator, when insufficient coins are in the tube. The check member 7 has spaced coinengaging teeth 9 and 10, and is pivoted at 8 to a lever 5 pivoted at 6. Normally both teeth engage coins in the pile 4, and when the topmost coin passes below the upper tooth 9 the check member 7 and lever 5 rock inwardly allowing contacts 12 and 13 controlling the delivery mechanism or indicator to open. If, however, the uppermost coin remains in engagement with the tooth 9 the check member still moves inwardly to open the contacts when the uppermost coin of the remainder of the pile passes below the lower tooth 10. Stops 11 on the check member limit its rocking movements.

Abstract: 653,532. Transferring freight containers to and from vehicles. NATIONAL FITCH CORPORATION. Feb. 16, 1948, No. 4454. Convention date, May 28, 1942. [Class 78 (iv)] In equipment for transferring freight containers to and from a vehicle, the container is connected to each of the usual propelling chains 51, Figs. 10, 12 and 14, by means of a slide 52 driven by the chain and a bar 53 connected at one end to the container C and adapted at the other end to be connected to either end of the slide 52; thus by changing the connection between the bar 53 and the slide 52 the container may be driven through a greater distance than the run of the chain 51. The slide 52 comprises two plates 71, Fig. 9, spaced apart by welded cross-pieces 72, 73, 74, the lower portions 75 of which serve to engage driving lugs 66 on the chain 51. The plates 71 slide on angle irons 37, Fig. 7, at each side of an I-beam 36 which supports the upper run of the chain 51 and serves together with angle irons 31 to guide the slide. The cross-pieces 72, 73 are formed with pins 76 engaged by hooks 86 or 87 on the bar 53. To draw a container on to the vehicle the chain 51 is caused to drive the slide 52 to extend beyond the end of the chain and the bar 53 connected as shown in Fig. 10. The chain is then driven to pull the container partly on to the vehicle and the drive reversed so that the slide 52 dis. engages the hook 86 and travels beneath it as shown in Fig. 12 until the hook 86 drops behind the cross-piece 73. The container may then be pulled fully on to the vehicle by driving the chain until the slide 52 extends beyond it as shown in Fig. 14. To reverse the motion the bar 53 is inverted so that the hook 87 is positioned to engage the pins 76. The connection between the bar 53 and the container C is of the form described in U.S.A. Specification 2,099,684 which is referred to. The remainder of the equipment is as described in Specification 557,793 with the exception that the sprockets at both ends of the propelling chain may be moved to adjust the tension in the chain.

Title: Process and apparatus for the separation of isotopes by fractional distillation
IPC: B01D59/04
Filed: 1944-03-14
Abstract: <PICT:0822001/III/1> <PICT:0822001/III/2> <PICT:0822001/III/3> High-vacuum fractional distillation apparatus for the separation of liquid mixtures comprises a series of cells, through which the liquid flows in succession, each cell having a heated tray or trough, wherein the liquid is partially evaporated, and an inclined roof which acts as a condenser for the vapours evolved in the trough below, each roof being so arranged that the condensate flows down the under-surface of the roof and drips down into the liquid in the trough of the preceding cell.  The apparatus is particularly suitable for the separation of isotopes; the separation of HCl35 and HCl37 from an azeotropic solution of HCl in water, and the separation of the isotopes of mercury and of potassium, are referred to.  In the apparatus shown, the troughs are heated by an electrical element 9, and the condenser-roofs are cooled by refrigerating coils 10.  The condensate in cell A runs down roof 3, and drips into trough 2 in cell B; while liquid overflows from trough 2 into trough 1 via the opening 7 in wall 5.  Thus a counter-current movement is established, in which the more volatile or lighter components are transferred from cell A to cell B, while the less-volatile or heavier components pass from cell B to cell A.  The casing 11 is evacuated by pump 11a.  The liquid mixture may be introduced through inlet X; the lighter component is then withdrawn through outlet Z, and the heavier component is withdrawn through outlet Y.  If it is desired to concentrate the light fraction only, inlet X is shut-off and the lowest cell is connected to the reservoir containing the liquid to be separated.  If, on the other hand, it is desired to concentrate the heavier fraction, the liquid mixture is introduced into the uppermost cell.  In an alternative embodiment, the cells are all on the same horizontal level, and the liquid may flow through the troughs in the form of a film.  In a further embodiment, a concentric annular arrangement of the several stages is adopted.  In an example relating to the separation of the isotopes of mercury, the average distance between the evaporating and condensing surfaces was about 15 mm., the pressure of non-condensables was maintained at about 10-7 mm., the temperature of the liquid was about 75 DEG  C., and the condensing temperature was 0 DEG  C.
