Non-amorphous (i.e. Crystalline, Semi-Crystalline or Fibrous) Cenium (IV) Phosphate is produced by reacting a solution of a Ce (IV) salt with phosphoric acid, the molar ratio of PO 4  to Ce in solution being at least 1À5, the precipitation temperature being between 35‹ C. and the boiling temperature of the solution obtained. The precipitated product is preferably left to digest at above 35‹ C. for such a time that crystalline Cenium (IV) phosphate is formed. In an example 0À025 M Ce(SO 4 ) 2 .4H 2 O in sulphuric acid is reacted with 6 M Phosphoric acid (i.e. PO 4 /Ce= 240) in sulphuric acid. The factors involved in obtaining an ordered structure in the precipitated product are (a) Temperature, (b) Digestion Time, (c) PO 4 /Ce ratio in solution, these factors being inter-related. The Cenium (IV) Phosphate of ordered structure obtained in the process shows greater ion-exchange capacity, and less tendency to hydrolyse, than amorphous Ce (IV) phosphate.

Abstract: 1289171 Powdered block and graft polymers DUNLOP HOLDINGS Ltd 19 May 1970 [23 May 1969] 26352/69 Headings C3G and C3P A powder is produced from an elastomeric block copolymer or an elastomeric graft copolymer, said copolymer having one or more amorphous non-elastomeric polymer blocks and one or more elastomeric polymer blocks, by contacting the block or graft copolymer with a dispersing liquid which is a non-solvent for at least one of the elastomeric polymer blocks and which is a very poor solvent for at least one of the amorphous non-elastomeric polymer blocks, at a temperature below the glass-transition temperature of the amorphous non-elastomeric polymeric block or blocks. The dispersing liquid may be acetone, acetaldehyde or an acetoacetic ester. The dispersions of copolymer may be stabilized by addition of a liquid non-solvent for the copolymer e.g. methanol and/or water; by addition of a non-elastomeric homopolymer having the same monomer units as the amorphous non-elastomeric polymer block e.g. polystyrene, and then admixture with a liquid non- solvent for the polymer; or by the addition of a surface active agent e.g. stearic acid, and a liquid non-solvent for the polymer. The examples relate to the following block copolymers:-styrene/isoprene/ethylene episulphide, styrene/butadiene, styrene/isoprene and acrylonitrile/isoprene; and to a graft copolymer of styrene and isoprene.

Abstract: 1289615 Advancing and shutter mechanism MINNESOTA MINING & MFG CO 6 Feb 1970 [7 Feb 1969] 5880/70 Heading G2A A camera has a shutter-actuating slide 34 which can be moved against a spring 37 to a tensioned position, and a film-advancing slide 41 which can be moved against a spring 43 to a tensioned position. As shown, the two slides are mounted above and below a base plate 32 mounted on the bottom wall of the camera by slot-and-stud arrangements. When the shutter release button 13 is pressed downwards, it acts via a lever 48 to engage slide 41 and push it to the right from the rest position of Fig.1. A lug 53 on slide 41 extends through an opening 54 in the base plate and an opening 55 in slide 34 to engage an edge 56 thereof. Thus as slide 41 moves to the right it takes slide 34 with it. Riveted to slide 34 is a resilient and flexible striker plate 58, which has a flanged front edge 63 and a downwardly depending arm 61. When the two slides are together, either at rest or moving, arm 61 is engagement with a cam edge 62a of slide 41, which causes it to take the flexed position shown in Fig. 2. This brings it clear of an arm 19 extending from the single-blade impact shutter 15. As the slides move to the right, a second lug 66 on slide 41 comes into engagement with a sloping edge 67 of opening 54, so causing the leading edge 65 of slide 41 to be flexed downwards, as in Fig. 6. This disengages lug 53 from slide 34, which is thus freed to be pulled back to its rest position by spring 37. Striker plate 58 is also no longer flexed out of its normal position, so that during this return movement its flange 63 strikes arm 19 and causes shutter blade 15 to pivot momentarily to its "open" position, Fig. 6. Slide 41 remains in its tensioned position as long as button 13 remains pressed. When the button is released, slide 41 is also released to be pulled back to its rest position by spring 43. As end 65 is now flexed downwards, it engages a lever 29 and rotates it in the direction of the arrow 30. This disengages a locking pin on lever 29 from a film take-up spool 27, and allows it to rotate clockwise under the action of an internal spring, and so winds on the film. As end 65 disengages from lever 29, this returns to its original position under spring action, and so locks spool 27 once more against rotation.

Abstract: 1310109 Holography PLESSEY CO Ltd 6 May 1970 [19 May 1969] 25489/69 Heading G2J [Also in Division G4] The invention relates to a photographic memory. Data in analogue form or as a binary dot matrix is stored in a photographic film in the form of small holograms. A plurality of uniformly spaced films or plates are arranged around the periphery of a disc rotated at high speed. A beam from a laser 4 is passed through a polarizer 6, an electro optical switch 5, a further polarizer 9 and reaches the disc 2. A reconstructed image is focused by lens 13 on a photo sensor arrangement consisting of an array of photo-diodes, which may be scanned to produce a digital signal, or to a vacuum camera tube which is sensitive to laser light, the tube then being scanned. Alternatively the beam may fall on a moving photo-sensitive plate or film if characters stored are to be printed. The laser beam is pulsed to coincide with the same photograph during each rotation of the disc and is synchronized by detecting a marker pulse on the disc by a photo-cell 10 or by magnetic means, amplifying the pulse in amplifier 11, supplying the pulse to a delay 12 and controlling a high tension source 8 coupled to the switch. The delay is variable to allow read-out of all the photographs. The switch 5 may comprise plates 7 producing a field causing rotationof the plane of polarisation of the beam or may comprise acousto-optical deflectors; piezo-electrically or mechanically operated mirror systems may be used and several tracks may be provided on the disc. The photographs may alternatively be arranged in tracks on a stationary plate scanned by the beam under the control of a plane mirror spinning about an axis passing through the tracks or on a strip of film wound round a hollow drum.
