Title: Method and apparatus for rendering saline water potable
Inventor: ASHLEY CARLYLE MARTIN
IPC: C02F1/22
Filed: 1958-11-11
Abstract: 907,643. Purifying water by freezing. CARRIER CORPORATION. Nov. 11, 1958, No. 36246/58. Class 29. Potable water is obtained from saline solution, e.g. sea water, by spraying the solution into a vacuum freezing chamber 104 so that part is frozen, separating the ice from the concentrated solution in a column 113 and washing the ice with potable water. As shown, the ice being lighter rises in column 113 and is discharged by a slinger 121 into a surrounding trough 118. Water vapour is withdrawn from chamber 104 by a compressor 109 which exhausts into a hood 120 above the column 113, the vapour being in part condensed on an evaporator 123. This condensate passes through a perforated plate 121<SP>1</SP> on to the surface of the ice and percolates through it into the concentrated solution thus washing the ice. The remaining water vapour melts the ice in trough 118 from which potable water flows through pipe 142 for use. Solution is withdrawn from the bottom of column 113 through pipe 134 and an ejector 125 withdraws non-condensible gases from hood 120. The incoming sea water is pre-cooled in exchanger 131 by the potable water and the concentrated solution. Specification 907,645 is referred to.

Abstract: 434,479. Changing signs. LAYCOCK, A., 5, Geraldine Road, Wandsworth, London. Dec. 29, 1933, No. 36536. [Class 3 (i)] In destination indicators and like signs comprising a non-endless display band which is wound on and off two rollers by two clutches operated by a single driving spindle, the driving member of each clutch being mounted on the spindle in such a manner that the clutch members of one clutch are in engagement when the clutch members of the second clutch are disengaged, one part 18 of each clutch is formed in or on a collar or sleeve 17, Fig. 3, axially movable on the spindle 19, a pin and helical slot connection 25, 26 being provided for effecting engagement &c. of the clutches and a braking device 23 acting directly upon the pin or slot to retard rotary movement thereof during the engagement and disengagement of the clutch members. The sleeve 17 may carry the pin 26 and work in a slot in the casing 5, or the pin and slot may be part of the driving spindle and the sleeve respectively. In a modification the pin is located on a loose collar spring-pressed between two fixed collars surrounding the movable clutch sleeve. The brake may take the form of a plate spring partly embracing the sleeve, or of a padded ring fitted with a helical spring adjusted by a grub screw. Fig. 8 shows a form in which both the helical gear wheels 70 and the clutch members 72 are moved axially on the driving spindle 6. Loose collars 74 on the gear wheels are connected by a half-tube or a tube 75 held from rotation by pin and slot 76, 77. A helical slot 78 in the tube 75 receives a pin 79 on the spring-pressed collar 80 in which the spindle 6 can rotate. In a further modification the driving spindle is slidable, carrying with it the clutch members and a loose rotatable spring-pressed sleeve.

Title: Improvements in or relating to sausage filling machines
IPC: A22C11/06
Filed: 1954-12-28
Abstract: 755,210. Sausage filling. ALEXANDERWERK AKT.-GES. Dec. 28, 1954 [Dec. 28, 1953], No. 37492/54. Class 28(2). A shutter 6'in the outlet 5 from a hydraulic sausage filling piston 4, is operated by a hydraulic piston 8, the shutter and piston being both controlled by a single main control valve 9. Pressure oil from a pump 10 passes through the main control valve 9 which distributes the oil to the underside of the piston 8 and also to a driving piston 2 on which the filling piston 4 is mounted, An adjustable pre-loaded valve 16 interposed before the main valve 9 ensures that sufficient pressure is exerted on the shutter piston 8 to operate it even when the pressure for driving the filling piston 4 is kept low when forcing easily flowable fillings. A relief valve 30 permits oil to flow back from the shutter piston 8 without building up excess pressure while the filling piston 4 is stationary. The piston 8 is easily disconnected from its shutter 6 by a catch 31. A manually controlled valve 27 to the oil reservoir adjusts the forcing oil pressure in accordance with the fluidity of the sausage meat.

Title: Improvements in and relating to turbine blading

Filed: 1957-12-03
Abstract: 843,287. Turbine rotor blading. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. June 27, 1958 [Dec. 3, 1957], No. 37654/57. Class 110 (3). A turbine blade assembly comprises batches of rotor blades interconnected by binding wire in which adjacent batches are coupled by a member or associated members having pivotal engagement about radial axes with the adjacent batches whilst being able to transmit circumferential motion from batch to batch. In Fig. 2, a coupling member for two batches of blades C and D interconnected by binding wires 11, 12 respectively consists of a short piece of wire 6 loosely held in two aligned holes 7 and 8 in the last blade 9 of batch C and in the first blade 10 of batch D. The wire 6 is of such a length as to permit slight circumferential movement. In operation, the junction wire 6 is pressed by centrifugal force against the sides of the holes 7 and 8 permitting forces to be circumferentially transmitted by friction, between adjacent batches. The junction wire 6 can also pivot about radial axes through holes 7 and 8 and consequently will not transmit motion between batches in an axial direction. In a modification the coupling member comprises a short tube, the open ends of which engage loosely over circumferential projections on the end blades of adjacent batches. Fig. 4 shows a coupling member 18 which at one end has a recess 20, shaped to engage loosely over a projection 22 on a blade of one batch, and has at the opposite end a projection 19 of reduced diameter loosely engaged in a hole 21 in a blade of an adjacent batch. Another modification comprises a coupling member which has projections of reduced diameter at opposite ends thereof loosely engaged in holes in blades of adjacent batches or in the open ends of tubular shaped binding wires.
