Title: Improvements relating to television
Inventor: STILLWELL PETER FREDERICK THOM
Filed: 1957-05-07
Abstract: 907,540. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 1, 1958 [May 7, 1957], No. 14570/57. Class 40 (3). Television apparatus comprises a pick-up tube, means for scanning a strip of an image and means for causing the strip to alternate between two predetermined positions spaced relative to the tube in a direction transverse to the strip whereby a stereoscopic representation of an image moving in said direction relative to the tube may be formed in response to signals derived from the tube. In the Figure, a pick-up tube 1 is mounted in an aircraft moving in the direction of the arrow and a ground scene A 1  B 1  is focused on the tube; the frame scanning is produced by the movement of the aircraft, and the line scanning is performed at a frequency of double that necessary to scan the image exactly once each frame. A " frame " scanning is applied to the tube by coils to which is applied a square waveform of half the frequency of the line scanning so that one " line " of the scene is scanned at A 1  and a further " line " of the scene is scanned at B 1 ; thus when the tube is at the further position shown, an image of the scene line B 1  is again scanned but this time as a scene line A 2  so that the picture signals comprise alternate " lines " of information representing different portions of the image. At the receiver the alternate lines of the received picture signals may be separated by regenerating the square-wave from the linesynchronizing pulses and adding this regenerated waveform and its inverse to two separate picture signals before applying them to cathoderay tubes or other display.

Filed: 1945-06-11
Abstract: 593,308. Casting concrete in situ; column centering. HAMILTON, W. June 11, 1945, No. 14780. [Class 20 (ii)] Centering for concrete columns cast in situ comprises angle pieces 10 at the corners of the centering adjustably secured in spaced relationship by locking bars 15 formed at both ends with teeth which engage similar teeth on ledges 12 formed on the outer faces of the angle pieces. The space between the angles is fitted with rectangular panels 23 which may be secured by being clamped by their edges between the angles 10 and internal angle fillets 20 which form the corner moulding faces. The clamping action is obtained by diagonal bolts 19 secured to the angle of the fillets and passing through holes in the angle of the angle pieces 10 which are reinforced by bosses 18 at these points. The locking bars may be secured in place by wedging pieces 16 which engage between the bars and projections 14 on the angle pieces spaced at an appropriate distance from the toothed ledges 12. Several angle pieces may be aligned end to end by means of lugs 11. Opposite edges of the panels 23 may be recessed from opposite faces as at 25 so that adjacent panels may interengage. The overlap of the panels with the limbs of the angle pieces is variable and the difference of the two panel dimensions may be twice the tolerance of this overlap to provide maximum variability in size of column with one set of panels, the panels being turned round when the adjustment in one direction has been exhausted. The angle pieces and fillets may be of aluminium and the panels of light alloy metal frames 24 with plywood filling.

Title: Improvements in or relating to the treatment of artificial filaments, threads, ribbons, fabrics and like materials
IPC: D06M13/08
Filed: 1939-05-23
Abstract: 529,142. Artificial filaments &c. HADLEY, D. J., and JACKSON, T. May 23, 1939. No. 15298. [Class 2 (ii)] The extensibility of artificial filaments threads, yarns, ribbons, fabrics, and like materials made of or containing an organic derivative of cellulose, is increased by subjecting the materials in the absence of tension sufficient to stretch them to the action of methyl formate, ethyl formate, n- or i-propyl formate, methyl propionate, or propylene chloride. Preferably the materials are treated under no tension so that they are free to shrink. The treating agents may be used alone or in admixture with one another or with diluents, e.g. glycol, glycerol, benzene, toluene, xylene, benzine, petroleum ether, kerosene, carbon tetrachloride, perchlorethylene, tetra- or decahydronaphthalene. The treatment may be effected at raised temperature. Materials containing filaments of high tenacity, obtained by wet spinning or by stretching to a high degree in presence of hot water, wet steam, or swelling agents, may be treated by the process. Staple fibres become crinkled or crimped. Cellulose acetate or other cellulose ester or ether materials may be treated. In an example, cellulose acetate yarn which has been stretched in wet steam is immersed in hank form in a solution of ethyl formate and kerosene and allowed to shrink. It is washed in petroleum ether and dried in warm air. Specifications 380,504 and 389,283, [Group XXII], are referred to. The Provisional Specification describes also the treatment of cellulose derivative textile materials with other esters of lower fatty acids, including methyl acetate.

Title: Carton handling apparatus
IPC: B65B43/18
Filed: 1963-04-19
Abstract: 979,916. Setting up collapsed cartons. FMC CORPORATION. April 19, 1963 [May 7, 1962], No. 15459/63. Heading B8C. Blank cartons are unloaded singly from a stack S by three suction cups 59 mounted on a suction bracket 58 and simultaneously opened to form a tube and deposited on a conveyer 14 on which they are rigidly held in the open rectangular tube form to be carried away ready for filling. Pivotal motion of a carrier plate 52 imparts an arcuate motion to another attached shaft, its housing 54 and the attached suction cup bracket 58, which is oscillated between a position overlying the conveyer 14 and a position adjacent the stack S. At the same time the carrier plate 52 moves a rod 64 to cause a bell crank 62 to pivot and rotate the housing 54 and suction cup bracket 58. The bracket is thus subjected to a compound movement due to the arcuate motion of the shaft within the housing 54 and to the independent rotation of the housing 54 so that the suction cups face the carton blank when picking it up and face downwards when the blank is released on to the conveyer. While the blank is being transferred by the suction cups a pair of fingers 71 are rotated to engage a side panel 23 of the carton and so erect the blank into a rectangular tube. A vacuum switch 91 connecting the vacuum supply to the cups is operated periodically so that when the blank is lowered above the conveyer the supply line to the cups is vented to atmosphere and the carton falls. The deposited erected blank is engaged by one of a series of lugs 98 on the conveyer chain 82 and, guided by a pair of upwardly flared members 101, 102, travels along two support members 103, 104 on to a channelsection rail 111, the horizontal upper face 112 of which frictionally engages the upper end flaps of the carton while the vertical surface 113 serves as a back stop for articles to be inserted into the carton. A rounded edge 116 guides the lower end flap into a slot 118 formed between the rail 111 and a flange 116. The other end of the carton is prepared for filling at a filling station 16 with its lower end flap travelling below the support shelf 114 and the upper flap and tabs travelling along the top face of the shelf 114 so that articles may be slid from the shelf into the carton. The snug fit of the carton against the described parts of the rail 111, the shelf 114 and pushing lug 98 ensure that a true rectangular form is maintained. The suction cups comprise a thick body portion with a thin annular flange around the outer circumference of the body which is bent against the carton panel when the vacuum is applied, the body portion not deforming to any extent. The flange diameter is sufficiently large so that a small applied pressure flattens the flange for a good seal and supplies a relatively large gripping force.
