Title: Improved apparatus for making ice blocks
IPC: F25C1/04
Filed: 1955-01-21
Abstract: 765,860. Ice making. GENERAL MOTORS CORPORATION. Jan. 21, 1955 [Feb. 1, 1954], No. 1967/55. Class 29 An ice tray 28 is pivotally mounted and movable relative to a flexible grid 22 which, consequent on such movement is distorted in order to eject ice blocks. The tray 28 (Figs. 1, 8) is mounted to pivot about a rod 18 by means of brackets 29 and has end pieces 38 pivotally attaching it to the links 36, and a bracket 47 presenting a convex face at 48 to the tray. Brackets 19 suspend the grid from the rod 18. A rod 31 is connected to a driving rod 42 by the links 33 and 41 and the stud 34, and at the ends of the grid are earpieces 24. Cam brackets 16 are fixed to the supporting structure and a wheel 45 is mounted to engage the convex face 48. In operation the rod 42 is turned in such a direction that the face 48 passes over the wheel 45 stretching the tray laterally and disengaging the ice blocks from the tray which then swings clear. At the same time the earpieces 24 on the grid engage the cams 16, being held firmly against them by the links 33, and, as turning of 42 continues the grid is stretched as the earpieces slide along the cams (Fig. 8) until finally both the tray and grid return to their original position, the ice blocks having dropped clear. A modification is the provision (Figs. 9, 13) of a stud 50d on one of the cams 16<SP>1</SP> and a stop arm 50c at.the other end of the support together with cams 50a, 50b at the ends of rod 31<SP>1</SP> and metal tabs 50g secured to the walls of the tray 28<SP>1</SP> in order to strike the ice blocks adhering to the grid. The stud 50d and stop arm 50c are so arranged as to allow one end of the grid a greater arc of travel than the other, thus twisting the grid. Tabs 50h may also be provided to cause the ice to adhere firmly to the grid while freezing. The invention is described for use in the freezing compartment of a domestic refrigerator cabinet and may be controlled by a motor giving a continuous batch supply of ice blocks or single freezings, a change of water being automatically fed to the tray at the end of each cycle.

Filed: 1971-01-18
Abstract: 1336029 Reverse osmosis membranes CANADIAN PATENTS & DEVELOPMENTS Ltd 18 Jan 1971 [26 Feb 1970] 2272/71 Heading B5B Reverse osmosis membranes of a cellulose ester or ether are prepared by a process in which a solution of the film forming cellulosic compound and a water soluble pore producing compound (e.g. magnesium perchlorate or formamide) in a volatile organic solvent (e.g. acetone) is cast to form a membrane of substantially uniform thickness, a portion of the solvent is evaporated and the membrane is immersed in cold water to effect gelation and removal of the pore producing compound therefrom, the casting step being performed with the casting surface maintained at the same temperature as the casting solution and in a substantially still atmosphere which is maintained at a temperature sufficiently different from the temperature of the casting solution on the casting surface to adjust the evaporation rate of the solvent from the cast membrane to produce a membrane having a higher product rate at the same separation factor than would be formed by casting the same solution in an atmosphere maintained at the same temperature as the solution. Preferably the atmosphere into which the membrane is cast initially contains vapour of the organic solvent, the atmosphere is maintained during casting at a temperature up to 27 C. higher than the temperature of the casting solution and surface, and the casting solution is at least at 0 C. and contains not more than 20 wt. per cent of the cellulose film-forming compound. After casting and gelation the resultant membrane may be heated in water at a temperature of 60-90 C. to reduce its pore size and then subjected to a water pressure treatment before being used in a reverse osmosis process. In examples acetone solutions of cellulose acetate containing water and either magnesium perchlorate or formamide are cast on to glass plates at temperatures of 0 C. and -10 C. in atmospheres maintained at 25 C. to 0 C. some of which initially contained acetone vapour. After partial evaporation of the solvent the membranes are immersed in cold water, heated in hot water and subjected to a water pressure treatment before being used in reverse osmosis water desalination processes. Reference has been directed by the Comptroller to Specifications 1,056,636 and 1,009,172.

Filed: 1919-01-30
Abstract: 142,197. Smith, F. A. Jan. 30, 1919. Regulating. - In engines in which a small charge is admitted separately and is ignited, then firing the main charge, the igniting-charge passes through a pipe FSC past a valve FSV to a box B separated from the cylinder by a suction-actuated valve) DV. The two valves are mounted on the same stem, so that one opens as the other shuts, the effect being that the engine acts only on the charge accumulated in the box B between the suction strokes. Instead of the valve FSV, the supply pipe FSC may be constricted. Fig. 4 shows a modification applied to a multicylinder engine, in which the supply of the charges to the boxes B is controlled by a piston valve FSP, operated by a suction-actuated piston P working in a chamber connected by a pipe sp to the induction pipe of the engine. The box B communicates with the engine cylinder through a plurality of chambers 1, 2, &c. increasing in size towards the cylinder. The main charge may be cut off, the engine then running on the igniting-charge only.

Bottles of polythene, cellulose esters, polyvinyl chloride or polystyrene are blow-moulded in two-part moulds 6 by extruding tubes 4, 5 through nozzles 2, 3 gripping them in. grooves 13, 14 in a pivoted gripping member 11, and moving the member 11 downwardly by an air cylinder 31 at a faster rate than the rate of extrusion to vary the wall thickness of the tubes, e.g. such that the thickest part of the tube forms the bottom and the thinnest part the neck of the bottle. In operation, the moulds are lowered and operate a switch causing actuation of the cylinder 31, moving a rod 30 downwardly, rocking a lever 26, and moving a rod 23 downwardly to cause a conical member 16 to close the grooves 13, 14 about the tubes. The rod 30 then moves the member 11 down at the desired rates, until an adjustable stop 36 engages a fixed stop 37, and an adjustable member 38 actuates a switch 35 to commence the upward movement of the rod 30. This causes anticlockwise rotation of the lever 26, while the rod 23 moves upwardly to free (under spring (15)-pressure) the tubes from the grooves 13, 14, and when an adjustable stop 28 engages a carriage 18, the member 11 is moved upwardly. The moulds are then moved upwardly and closed about the tubes, and the articles blown. A safety switch Fig. 3A, (not shown) prevents the moulds from closing until the grippers return to a datum position.
