Title: The coating of metal surfaces with polythene or polythene compositions
IPC: B05D1/30
Filed: 1944-01-31
Abstract: <PICT:0574309/IV/1> Polythene sheets, containers and removable liners are produced by first coating a rigid and impervious surface with a separating agent such as a high melting point grease, aluminium stearate, sodium silicate or a detergent, and then covering with a composition comprising normally solid polythene by positioning said surface at an angle to the horizontal, heating the surface to a temperature between 30 DEG  C. below the melting point of the composition and 210 DEG  C., allowing said composition in the molten state to flow over said surface and cooling the surface to convert the composition to the solid state.  According to the preferred method of operating, the surface of a drum 1 is coated with a separating agent and, together with a polythene-charged distributer 2, is placed in an air oven at 140 DEG  C.  The polythene melts and flows evenly down the sides of the drum, leaving a coating which, after cooling, is stripped off.  Plain metal surfaces may be treated in a similar manner.  Compositions consisting of polythene and 5 to 50 per cent polyisobutylene are particularly suitable. Specifications 551,339 and 566,745, [both in Group III], are referred to.

Patent GB-927364-A (GB)
Title: Improvements in or relating to package irradiation systems
Inventor: JEFFERSON SIDNEY
IPC: G21K5/02
Filed: 1960-01-20
Abstract: 927,364. Irradiation apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 12, 1961 [Jan. 20, 1960], No. 2155/60. Class 98 (1). In apparatus for irradiating packages, the packages are conveyed in pairs, one above the other, past the faces of a plate-like radiation source, the position of the packages in each pair reversed, and then conveyed again past the source. Fig. 3 illustrates the principle, each package-pair 3a, 3b being conveyed past a plate-like radiation source 1. The parts a, b of the packages thus receive most radiation, and the parts c, d least. If the position of the packages in each pair is now reversed, so that the parts c, d are now nearest to the source, these receive most radiation, and parts a, b least. Thus if the packages are traversed past the source first in one position and then in the other, the dosage received by every package will tend to be uniformly distributed, at the same time utilizing a large part of the solid 4# angle of radiation from the source. In Fig. 5, the packages are pivotally mounted at each end of a double-armed lever 5, mounted at its centre point on a hanger 6. This depends from a wheel 7, enabling it to be run along a rail 8. The position of the upper and lower packages can be reversed as shown in dotted lines. Fig. 6 (not shown) illustrates an alternative reversal method. The carrying rail 8 enters the radiation cell 9 through a sinuous passage 10a, and leaves through a similar passage 10b, making a number of passes 11-20 parallel to two plate-like radiation sources 1a, 1b. It will be seen that these two sources will irradiate opposite sides of the containers. After one circuit through the cell, the packages are switched to a return rail 8a, the packages reversed as above described at a station 21, and then sent a further circuit through the cell. In order to operate a continuous (as distinct from a batch-wise) process, untreated packages are intercalated with partially irradiated packages; thus at switch-point 24 those packages which have made only one circuit through the cell are switched to the return rail 8a, while those which have made two circuits are switched to the delivery point 25. The sources 1a, 1b may be racks containing vertical tiers of horizontal cobalt 60 pencils, and capable of being lowered into water-filled pits in the floor when not in use. Specification 779,134 is referred to.

Filed: 1928-01-23
Abstract: 284,328. Gilbert Co., A. C., (Assignees of Anketell, E. N.). Jan. 2R, 1927, [Convention date]. Model machines; mechanical constructions, details for building up.-A toy hoisting-mechanism comprises a pair of rotatably mounted winding- drums having a common driving shaft that is fixed to one of the drums and is axially movable relative to its mounting and to the other drum to connect and disconnect the one drum to and from the other. As shown in Fig. 1, a toy crane comprises a jib 23 pivoted at its lower end to a platform 11 rotatably mounted on a wheeled base 10. The jib is controlled by a cord 32 attached at one end to the head of the jib and wound at the other around a shaft 33, one end of which is cranked to form a handle and carries a toothed wheel 36 normally engaged by a locking pawl 39. The crane operates a grab, Figs. 1 and 6, comprising two jaws 41, 42 pivotally mounted on a shaft 43 carrying two pulleys 48, 49, and a pivoted weight 50. The jaws are connected by pivoted links 44, 45 to a frame 46 carrying a third pulley 47. The grab is supported by two cords 51, 52 passing over pulleys 27 on the head of the jib. The cord 52 is attached directly to the frame 46 while the cord 51 passes around the pulleys 48, 47, 49 in the order named and is then attached to the frame. The other ends of the cords are wound on drums 54, 55, Fig. 3, both mounted on a shaft 56 one end of which is cranked to form a handle 61. The drum 54-is secured to the shaft. The drum 55 is freely mounted on the shaft but is rotated with the drum 54 by the engagement of teeth 72, 73 formed on the adjacent flanges of the drums. The drums are disengaged by an axial movement of the shaft. The drum 55 is prevented from moving when disengaged, by a brake comprising a resilient member 77, Fig. 9, secured to the frame and engaging the groove in a pulley 75 secured to the drum. A plate 78 enters the groove in the pulley 75 to prevent axial movement of the drum 55. By manipulation of the handle 61, the grab may be opened or closed and raised or lowered in either condition. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification, Fig. 12, (Cancelled) in which three drums 90, 91, 92 are provided. The jib-control cord 32 is wound on the drum 90 and the hoisting and control cords 51, 52 for the grab on drums 92, 91, respectively. Gear wheels 115, 124 are mounted on the spindles of drums 91, 92 and are engaged by a pinion 129 on an axially-slidable operating shaft 126, the arrangement being such that the pinion is continuously in engagement with the wheel 124 but may be moved with the shaft into and out of engagement with the wheel 115. The drum 91 is provided with a brake similar to that shown in Fig. 9. The plates 96, 97 are provided with regularly positioned holes to receive the spindles and for attachment to a base-plate. The hoisting-mechanism may be applied to any toy in which such a device.is required. This subject-matter does not appear in the Specification as accepted.

Patent GB-870356-A (GB)
Title: Preparation of polyvinyl alcohol
IPC: C08F18/08
Filed: 1959-01-21
Abstract: Polyvinyl alcohol of high viscosity e.g. 100 to 300 centipoises, is prepared by polymerizing vinyl acetate at the reflux temperature of the vinyl acetate reaction mixture in the presence of a low concentration, preferably between 0,0035 and 0,0055 weight per cent based on the weight of vinyl acetate, of an alkyl peroxydicarbonate ester catalyst to convert not more than 77% of the vinyl acetate to polyvinyl acetate, and hydrolysing the polyvinyl acetate until at least 75% of its acetyl groups has been converted to hydroxyl groups. Lower viscosity polyvinyl alcohol, e.g. of 25 to 75 centipoises, is produced by polymerizing the vinyl acetate in the presence of a small amount of acetaldehyde, preferably between 8 to 30 c.c. thereof per 20 pounds of vinyl acetate.  The peroxydicarbonate ester catalysts have the formula:  <FORM:0870356/IV (a)/1> where R1 and R2 are alkyl radicals such as those each containing up to 18 carbon atoms, e.g. methyl, ethyl, isopropyl, n-propyl, isobutyl and n-butyl. Polymerization is by suspension or bead techniques in which vinyl acetate is reacted in aqueous medium in the presence of protective colloids, e.g. small quantities of polyvinyl alcohol.  The catalyst is added to a reaction mixture refluxing at between 65 DEG C. and 75 DEG C. where a vinyl acetate conversion of 50% to 77% is required. Acetaldehyde, if employed, is added to the reaction mixture prior to, or together with, the catalyst.  Hydrolysis is defined as including alcoholysis, e.g. with an alkanol of 1 to 4 carbon atoms such as methanol or ethanol, as well as acid hydrolysis using sulphuric or phosphoric acid as a strong acid catalyst.  In alcoholysis alkali metal alkoxides may be used as catalysts, employing between 0,5% and 5% by weight thereof based on the polyvinyl acetate. Hydrolysis may be continued until 95% conversion of acetyl groups is achieved. Specification 596,779 is referred to.
