Abstract: 1,088,762. Code markings on films. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 24, 1965 [May 22, 1964], No. 21373/64. Heading G2C. In a device for allowing radiation to fall on a sensitive film through an aperture, a number of shutters are so arranged so that any desired combination of them may be interposed in the aperture. The device is used for printing an identification coding mark on films which are to form part of film badges acting as radiation dosimeters. Six knurled wheels 9, each carrying engraved decimal digits Fig. 4 (not shown), are mounted at one end of a housing 8, and are each connected via a gear train to a pinion wheel 21. Each pinion 21 has secured to it a group of five cams 23. Each pinion 21 also meshes with another pinion 24, each pinion 24 also carrying a group of five cams 26. Each cam 26 is aligned with a corresponding cam 23, the two having complementary profiles. The profiles are such that the cams can have ten different angular positions, spaced 36‹ apart. Above the film 1 are disposed thirty shutters 6, arranged in six groups of five each. Each shutter is formed as a foot part of a lever 7, the other end of the lever having two surfaces 28 which bear on the surfaces of a pair of cams 23, 26. X-rays from a source 3 are collimated by a tube 4 and are directed through an aperture 2 on to the film 1. Each shutter 6 is controlled by the cams so that it either extends or does not extend into aperture 2. A "2 in 5" binary code is used, so that in each rotary position of the cams, three shutters are in one position and two in the other. Since there are thirty shutters, the coding mark on the film consists of thirty strips, along one short edge of the film, which are selectively blackened by X-ray exposure, and represent a six digit number in binary coded form, as set on the wheels 9.

Figs. 5, 6, and 7 show respectively a front elevation, sectional side elevation, and plan of a portion of the apparatus, the ring of lenses being omitted from Fig. 5. A toothed wheel 39 on the shaft 36 carrying the ring of lenses 37 meshes with a toothed wheel 34 on a shaft 32 which also carries a toothed wheel 33 meshing with a toothed wheel 25, all the wheels being of equal diameter and pitch. The wheel 39 is indirectly geared to the driving handle, and the shaft 19 carrying the wheel 25 carries also a disc 20 having teeth 21 which enter the perforations in the film and move the film lengthwise and edgewise. The shaft 36 is mounted in fixed bearings 35 but the bearings 18 for the shaft 19 are mounted on a slide 17 which can be moved vertically for film-centring 'by means of a screw 26 turned by means of a head 27. The shaft 32 is mounted in bearings on a plate 28 which is mounted on a fixed pivot 29 and connected by a slot and screw 30 to the slide 17, the axis of the pivot 29 passing through the meshing point of the wheels 34, 39 so that these wheels remain in mesh in all positions of the plate 17. The film is kept in engagement with the pins 21 by the flat surface 22 of a shoe 22a which is mounted on a flexible projection 18<a> from the bearing 18 and has an arm 23 enabling it to be pressed away from the pins when the film is being threaded &c. A bar 13 is pressed against the edge of the film by strip springs 15, the lower spring being engaged by an extension 54 of a guide piece 51 mounted on a pivot 52. The spindle 47 of a roller 48 carried by a rod 42 which can be pushed downwards in opposition to the action of a spring 45 projects into a vertical slot in the piece 51, and the bottom of the slot is sloped' so that as the spindle 47 moves downwards it passes out of the slot and presses the piece 51 against the lower spring 15 and lifts the bar 13 from the edge of the film. When the film loop between the gate and the lower sprocket shortens, it may be restored by first pressing on the arm 23 to lift the shoe 22<a> and then lowering the roller 48 so as to bear on the film and draw it through the gate. The lenses may each be held in a separate frame 40, Fig. 4, the frames being provided with slots 41 engaged bv screws which secure the frames to the disc 37 and permit their positions to be adjusted thereon.

Title: Process and apparatus for producing heat shrinkable tubing
IPC: B29C48/90
Filed: 1965-05-21
Abstract: 1,056,970. Heat shrinkable tubing. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 21, 1965 [May 22, 1964], No. 21595/65. Heading B5A. Heat shrinkable tubing is made by heating an extruded tube of crystalline polymeric material to at least its crystalline melting point at which temperature the material exhibits elastomeric properties, applying fluid under pressure to expand the tube to the required predetermined diameter as it is drawn through a die which extends through the heating and cooling chambers. The metal die 5 extends through a heating chamber 6 circulated by hot oil, a cooling chamber 7 and a rinsing chamber 8. Extruded tubing 2 of crystalline polymeric material, wrapped around by tape 4 from a reel 4a which acts as a carrier for the tubing, is continuously pulled through the metal tube 5 by a driven take-up reel 16 for the tape. Compressed air is applied to the tubing by a pump, one end of the tubing being attached to the pump while the other end is closed. In the heating chamber the tubing expands and since the internal pressure is maintained in the cooling and rinsing chambers the tubing sets at the expanded diameter, which is in fact equal to that of the metal tube minus the thickness of the carrier tape. The expanded tubing is coiled on a rotating table 11. The metal tube 5 is perforated so that hot oil enters it in the heating chamber to increase heat circulation, the oil being washed from the expanded tubing in the rinsing chamber. The tubing may be patterned by using a roughened or embossed carrier tape. The carrier tape may be in the form of an endless belt and may be of metal foil, fulric plastics or elastomeric coated material. The crystalline polymeric material may be produced by subjecting a crystalline polymer to irradiation, or may be chemically cross-linked polymers or mixtures of chemically cross-linked elastomers and crystalline polymers. Examples include P.T.F.E., polyethylene, polypropylene, P.V.C., P.V.D. and polyamides.

Title: Improvements in and relating to the production of phosphoric esters
IPC: C07F9/08
Filed: 1947-12-08
Abstract: Neutral esters of phosphoric acid are manufactured by reacting phosphorous pentoxide or an organic metaphosphate or pyrophosphate with excess of an organic ether free from polar substituents, at a temperature of 65-180 DEG  C. (preferably 140-180 DEG  C.).  The reaction may be carried out in the absence of a catalyst, but improved yields are obtained by the use of an esterification catalyst, e.g. iodine, ferric chloride, sulphuric acid, phosphoric acid or cobaltous acetate.  When using phosphorus pentoxide, the molar ratio of ether thereto is preferably between 3 : 1 and 10 : 1. The alternative starting materials may be, for example, ethyl metaphosphate or tetraethylpyrophosphate, or the residue from a previous reaction using phosphorus pentoxide.  The ether may be an alkyl ether (simple or mixed) or an aryl ether, e.g. diethyl, di-n-propyl or di-isobutyl ether, methyl ethyl ether (which yields a mixture of diethyl methyl and dimethyl ethyl phosphates), or diphenyl ether.  Examples describe the preparation of triphenyl and triethyl phosphates.  The products are useful as plasticizers, spinning lubricants, antistatic agents, catalysts or surface-active agents.
