Patent GB-579022-A (GB)
Title: Improvements in or relating to films consisting essentially of normally solid ethylene polymers
IPC: B32B37/00
Filed: 1944-09-01
Abstract: A clear film of a normally solid ethylene polymer is obtained by forming a molten film of the polymer, cooling the film until substantially maximum haze formation has occurred, and thereafter heating the film until the haze disappears.  A film of the desired thickness may be cast or extruded from a melt of the polymer on to a support, and may be permitted to solidify and cool until maximum haze appears.  The film is then heated until the haze just disappears, the temperature of <PICT:0579022/IV/1> clarity being usually below the melting point of the polymer, and the film is then cooled again. Instead of casting from a melt, the film may be cast from a solution in an organic solvent or from a dispersion.  The solvent or dispersing medium is evaporated and the film is heated to a temperature above the melting point, cooled until maximum haze appears, and then further heated as in the treatment of a melt-cast film.  As shown, film 40 is cast from solution or extruded from a melt upon an endless belt 6 of chromium-plated steel.  Solvent if present is evaporated in the region 1.  If the film is cast from solution, the polymer is brought to the melting point by a heater 37 which may be omitted if the polymer is extruded from a melt.  Nozzles 9 direct a cooling fluid against the underside of belt 6, and the film is cooled, haze formation occurring in the region 2.  The film is heated in region 3 by means of the device 12 and the haze is removed.  Nozzles 14 direct a cooling fluid against the belt 6 and the film is cooled sufficiently for stripping.  The film is wound up on roll 17.  The ethylene polymer may be derived from ethylene only, or from ethylene in admixture with another polymerizable unsaturated organic compound.  In an example, a solution of ethylene polymer, of molecular weight 9000, in xylene is cast on to a metal plate enclosed in an air-tight casing.  The film is heated and warm air is passed over it to remove the xylene. Heating is continued till the film has melted.  The film is cooled until haze formation is complete and then reheated till it is clear.  It is then cooled to room temperature and stripped. Specifications 471,590, 474,426 and 497,643 are referred to.

Title: Improvements in or relating to Speed Indicators.
IPC: G01P3/06
Filed: 1916-11-21
Abstract: 102,611. Soc. Aera. Dec. 4, 1915, [Con vention date]. Differential speed indicators; transmission mechanism. - In apparatus having a roller, mounted on a variablespeed screwed shaft, engaging a constant-speed revolving disk and operating an indicating-hand, the constant drive for the disk is obtained from the variable shaft through a slipping clutch controlled by a centrifugal braking- device. A unidirectional drive is obtained from the main shaft bv loose bevelwheels 3, 3<1>, Fig. 2, which are engaged by a bevel-pinion 2 and bear grooved desks 5. Springs 6 passing round the disks tend to force pawls 7, Fig. 5, into oppositely-directed ratchet grooves in a shaft 4. A shaft 10, Fig. 4, driven from the shaft 4 has mounted thereon a wheel 15 connected to the shaft by a spiral spring 13, one end of which is secured to the shaft, and the other is in frictional engagement with a casing 14 carried by the wheel. Secured to the wheel 15 by a sleeve 18 carried by a ball bearing 17 is a friction disk 19. Movement of the wheel, and thus of the disk 19, is rendered constant by centrifugal members 33, Figs. 6 and 7, pivoted to a plate 24' on a shaft 24 driven by multiplying-gear from the wheel 15. Outward movement of the members 33 against an adjustable spiral spring 26 causes brake pins 35 to engage a fixed casing 36, and slipping to occur between the spring 13 and the wheel 15. A wheel 11 on the shaft 10 drives, through a crown-wheel 37, Fig. 3, a screwed shaft 39, on which is mounted a sleeve bearing a roller 40 engaging the disk 19. Movement of the roller due to change of speed of the shaft 39 causes a plate 41 connected thereto to move along rods 42 and operate pointers 46, 52 through rack-andpinion gearing, the pointer 52 being arranged to show higher speeds.

Title: Apparatus for collecting liquids in measured volumes
IPC: G01F23/292
Filed: 1949-06-24
Abstract: 665,901. Photo-electric liquid level controls. WELLS, R. A., SETTATREE, A. A., KEM. BER, N. F., and YARDLEY, V. A. June 23, 1950 [June 24, 1949], No. 16826/49. Class 40 (iii). Containers are conveyed in succession to a liquid dispensing position and, when the liquid reaches a predetermined level in the operative container, a photo-electric control device steps the conveyer. The liquid supply may also be shut off by the same control device during stepping of the conveyer. As shown, flasks 7 are adjustably and detachably secured at spaced positions to the periphery of a turntable 6 adapted to be driven through a slipping clutch by an electric motor 20. When a flask is advanced to the dispensing position, shown in Fig. 1, light from a fixed lamp 30 is focussed by a fixed lens system 33 on to a point coincidental with the desired level in the flask and passes to a photo-cell 34 without interruption. When the liquid being dispensed reaches the desired level the beam is interrupted first by refraction and then by internal reflection within the liquid whereupon the cell output, amplified at 50, Fig. 4, actuates the change-over relay 51 to switch the turntable drive motor 20 into circuit and deenergize a locking magnet 46 to release the turntable which is then advanced by the motor. The beam is kept interrupted by a screen 39 forming a part of the turntable periphery until the next dispensing position is reached when the beam passes through a corresponding aperture 40 in the screen and through the flask now in dispensing position to the photo-cell which changes over the relay 51 to stop the motor and energize the locking magnet 46 which rocks a detent 43 into a corresponding notch 44 in a gear-wheel 45 on the turntable spindle 4 to lock the latter. The slipping clutch caters for any over-run of the motor. The detent 43 also actuates contacts 63 to energize a solenoid 61 in the energized position of the locking magnet 46, the solenoid 61 when so operated opening a valve in the liquid supply pipe to commence filling of the new operative container. Further apertures 40 are provided in the screen 39 corresponding to a further notch or notches 44a of smaller depth than notches 44 provided at points around the gear-wheel 45 which do not correspond to a dispensing position but to a zero position where the turntable is locked and the motor stopped as above described, but the throw of the detent 43 is insufficient to close contacts 63. The fluid supply therefore remains cut-off at these positions which will occur at the end of a filling sequence. The light beam may be interrupted alternatively by an opaque float in each flask as it is filled.
