Title: Process and apparatus for cooling thermoplastic sheets or films
IPC: B29C48/10
Filed: 1966-12-21
Abstract: 1,123,318. Cooling thermoplastic films. ZELLSTOFFABRIK WALDHOF. 21 Dec., 1966 [23 Dec., 1965], No. 57156/66. Headings B5A and B5B. Thermoplastic films or sheets made by a blow moulding process, are cooled with a gaseous media enriched with a mist-like atomized liquid, immediately after extrusion from a tubular die and before drawing off. The film may be cooled on its inside or outside surface. Air enriched with a fine spray of atomized liquid is supplied to a lower cooling ring 8 through pipes 11. Baffles 12, in the annular space 13 effect uniform distribution of the pressure ratio by causing turbulence, thus directing the cooling medium coming from the air gap 14, under an adjustable lip 15, on to all sides of the outside wall of the tubular film 10, the cooling medium streaming upwards along the outside tube wall. Cooling ring 9 works in like manner, the cooling medium being directed downwards through air gap 19. The size of the liquid drops is at or less than 20 Á and the vaporization temperature of the atomized liquid is preferably below the setting point of the film. The amount of liquid coming into contact with the film is such that it vaporizes between the die and the draw-off device. The liquid may be blown off with heated air moving in the direction opposite to the film. Alternatively (Fig. 2), the cooling medium may be introduced into a mandrel head 20 through a pipe 23 passing upwards in the centre of housing head 21, the cooling medium being insulated from the temperature of the housing head by insulation means 27. A baffle 26 directs the cooling medium on to the inside wall of the film, the cooling medium also serving to blow the film. Air is removed through suction pipe 25. Additional cooling from the outside may be effected as above. Films with uniformly grained surfaces may be produced.

Abstract: 1419976 Systems of folding planes C B AROCA 13 Dec 1972 [14 Dec 1971] 57494/72 Heading E1W [Also in Division A4]  A structure of. folding planar elements for forming a reflecting surface or a roof or display area comprises a number of series of planar elements 8. These elements in any one series being joined by hinges 7 so as to fold into a zig-zag or concertina form and those adjacent series of elements linked by a pantographic framework of hinged arms 4, 5 which bring adjacent series of elements into opposed spaced relationship when folded. When in extended array elements in each and adjacent arrays abut at their edges. This abutment is effected by providing increasingly broader central spacing elements of each double hinge 7 in succeeding series of elements and correspondingly increasing projections 17 of each element beyond the hinge axis in succeeding arrays. A similar arrangement in the connection of the elements to the brackets 6 where they are mounted on the pantograph struts 4 provides similar abutment on the opposite edges. The junctions 4 of the pantograph framework 4 may be connected to a node of a folding supporting framework 13.

Abstract: 1,165,920. Fluid pressure control valves &c. PAN AMERICAN PETROLEUM CORP. 30 Dec., 1966, No. 58449/66. Heading F2V. A valve, for controlling fluid flow from a well, comprises a mandrel 12, a housing 16, removably fixed within it, and a sleeve 26 which carries a piston 33 and is slidably mounted within the housing, the mandrel, housing and sleeve being apertured as at 14, 22 and 29 respectively. A source of fluid pressure, controlled from outside the valve, is applied to the uppermost part of a solid portion 27 of the sleeve 26, thereby retaining the valve-components in the position shown in which fluid flows in the direction of the arrows from within the housing to a space enclosed between the mandrel and well tubing 11. Upon removal of this pressure source, pressure of the controlled fluid raises the sleeve 26, which thus closes ports 22 in the housing, and also piston 33 which then seats at 32, the arrangement being such that ports 22 are fully closed before the piston is seated. The upper end of the housing is provided with a series of longitudinal slots 17 circumferentially spaced thus allowing the outside diameter to be reduced by a force applied externally of the housing when it is desired to remove the latter.

Abstract: 1418649 Distilling solutions of waste solids HANOVER RESEARCH CORP 29 Dec 1972 60118/72 Heading B1B In a process for recovering clean water from dilute solution of waste solids, a relatively non- volatile oil is added to the concentrated solution, so that after further concentration by evaporation and condensing of the water vapour to obtain clean water the waste solid/ oil residue is fluid and pumpable. In one embodiment the initial dilute solution is heated to concentrate it before the addition of the oil, and the water vapour is condensed to obtain clean water. In another embodiment, as illustrated, the initial dilute solution 1 is centrifuged at 8 to provide a very dilute waste solids solution which is fed to tank 12, and a concentrated waste solids solution which is then mixed with the relatively non-volatile oil from 57 and fed to tank 10. The solution from tank 12 is pumped through line 14 to the first stage or fourth effect evaporator 15, for concentration in the associated multiple effect evaporator, the product clean water is collected from line 19, and concentrated waste solution is discharged via line 49 and mixed with the concentrated waste solids and oil mixture from tank 10 passing to the first stage 62 of a drying evaporator. Product clean water from the drying evaporator is collected at line 65, and the remaining slurry of waste solids in oil is withdrawn by pump 81, and passed to centrifuge 85 where oil is separated for recycling via line 57 to tank 10, and the remaining waste solid/oil is passed via line 89 for solid/liquid separation in press 90 and discharge.

With negative current on line i.e. D1 conductive transistors T1 and TEC will be blocked causing transistors TC, T4 to be conductive and transistor T5 to be blocked hence a capacitor C will not charge. In this condition there is no outputs on lines S, Sa. A positive start signal applied at EC blocks diode D1 hence the voltage across R1 renders transistors T1, TEC, T2, T4 conductive and T3, T5 will be blocked hence capacitor C will be charged and positive outputs will appear on lines S, Sa. Due to capacitor C, positive modulated current will not change this condition. On receipt of negative modulated current the transistors all change to the opposite state hence a positive output will appear on line S through T5 and a break down device ZN3 from line M but line Sa will not have an output. Capacitor C will become discharged. This is also the condition in the first 350 m.sec. after negative (line 3) current is restored. After 350 m.sec. when capacitor C has discharged the circuit reverts to its original state with no output on either S, Sa. The various conditions of operation are given in a table in the Specification. The device may be incorporated anywhere on a line i.e. at a receiver, a transmitter, or in an exchange.
