As shown, each output device comprises a transfer gate 11 and a charge sensing node 12. In operation of the device, the applied bias potentials, which create a plane of maximum potential energy 23 between two depletion regions, can be adjusted to vary the spectral sensitivity of each photoelement 10. Alternatively, the thickness of layer 15 and/or the surface doping concentration can be varied to establish the position of layer 23. Colour information can be extracted from incident light by feeding the amplified signal from each of three detectors to three scaling amplifiers and then summing the blue, green and red signals from each scaling amplifier in three adding stages. An area array scanner, Fig. 5, may be constructed, comprising a multiplicity of sets of shift registers 71 with transparent electrodes, of which electrodes such as 72a or 72d are biased to serve as photoelements, 72t forms a transfer gate, and 72x is the electrode of a charge transfer node. Each shift register of the scanner is connected to one of three further shift registers 75, 76, 77 which transfer charge to detection amplifiers 28, 29, 30, prior to scaling and summation.

Abstract: 1407643 Continuous casting CONCAST AG 13 Aug 1973 [14 Aug 1972] 38314/73 Heading B3F [Also in Division G3] The short sides 2a, 2b of a rectangular continuous casting mould are positioned by electric actuators 3, 4 which operate sequentially in response to the difference between actual position signals and desired position signals from setting means 12. The latter comprise digital analogue convertors and provide for separately digitally setting the upper and lower spacing l+#l and l and also the initial lower spacing l 0 . The sequence is controlled by logic circuits 14, 15 (also Fig. 4, not shown) and is set out in Fig. 3 (not shown). The sides are actuated alternately first to get them upright, then at spacing l, then the top only to spacing l+#l. They are then centralized with respect to a guide apron by (manually) setting any discrepancy a on a transmitter 13 which causes the appropriate adjustment to be made to each side in turn. Comparison between desired and actual position signals is made at selsyn devices 11, which have stators connected to the desired position signal sources and rotors driven by the actuators. Output signals are fed to the logic circuits which distinguish between large and small descrepancies to produce high and low speed signals to motors 9 which drive screw- and nut actuators 3 directly and 4 via electromagnetic clutches 7.

Title: Impact resistant nitrile polymer films
IPC: C08K5/12
Filed: 1967-08-22
Abstract: 1,200,328. Nitrile polymer films. STANDARD OIL CO. 22 Aug., 1967 [6 Sept., 1966], No. 38632/67. Heading B5B. [Also in Division C3] Impact resistant nitrile polymer film is produced by forming a solution of a nitrile polymer in a mixture of a "primary solvent" and a "secondary solvent" into a film (particularly by casting), biaxially orientating the film thereby formed and drying the film so that it is substantially free of the "primary solvent". The nitrile polymer may be a homopolymer or a copolymer of a nitrile monomer having the general formula wherein R is a hydrocarbon group, hydrogen or halogen, the copolymer containing up to 10% by weight of a monomer copolymerizable with the nitrile monomer. The term "primary solvent" is defined as meaning a liquid organic compound which is a good solvent for nitrile polymers and which is sufficiently volatile to be substantially completely removable from the film by evaporation when the film is heated to a temperature below the melting-point of the film. The primary solvent is preferably dimethyl formamide. The term ''secondary solvent" is defined as meaning a lower alkyl ester of a polybasic carboxylic acid, the alkyl group containing 1 to 3 carbon atoms. The ester may be R-(-COOR<SP>1</SP>) n , wherein R is a hydrocarbon radical having from 5 to 8 carbon atoms, R<SP>1</SP> is an alkyl group having from 1 to 3 carbon atoms and n is 2 to 4. The nitrile monomer may be acrylonitrile, methacrylonitrile or alphachloro acrylonitrile. The secondary solvent may be dimethyl or diethyl phthalate, dimethyl sebacate or dimethyl isophthalate. About 1 to about 30%, preferably about 2 to about 5% by weight, based on the nitrile polymer, of the secondary solvent may be incorporated in the primary solvent used for dissolving the nitrile polymer. The monomers copolymerizable with the nitrile polymer may be monoalkenyl or polyalkenyl monomers. Examples of monoalkenyl monomers which may be used are esters of acrylic and methacrylic acids, vinyl esters such as vinyl acetate, vinyl aromatics such as styrene, vinyl amides such as acrylamide, vinyl halides, and the lower olefins. The film formed may be stretched longitudinally at about 145‹ to 180‹ F. and at a stretch ratio of from about 2: 1 to 4: 1, and stretched transversely at 145‹ to 180‹ F. at the same stretch ratio. It may then be heat set at about 250‹ to 485‹ F. for from a fraction of a second up to about 5 minutes, while being held to prevent either lateral or longitudinal shrinkage.

Title: Improvements in or relating to Rubber Tubes and Hoses
Inventor: BARKER REGINALD CHARLES
IPC: B29C53/30
Filed: 1965-09-14
Abstract: 1,166,452. Moulding corrugated tubes. AVON RUBBER CO. Ltd. 13 Sept., 1966 [14 Sept., 1965], No. 39258/65. Heading B5A. [Also in Division F2] Hoses or tubes of natural rubber, synthetic elastomer or blends thereof and which may be reinforced, are convoluted without thinning of the tube wall by mounting the unconvoluted tube 30, which is at least partially unvulcanized, on a rotated mandrel 10, on which it may be heated, which mandrel 10 is provided with a circumferential trough 18 and ribs 16, which may be of slightly larger diameter than that of the tube 30 when it is then slightly expanded, or is of equal or preferably smaller diameter, and towards which rotating mandrel 10 is gradually displaced a support 28 carrying a freely rotatable roller 20 which engages the wall of the tube 30 to form convexly and concavely shaped parts. The convoluted tube is placed on a cylindrical mandrel of the required final tube diameter and compressed to the required final length, for vulcanization, between end-pieces slidable on the mandrel. The ribs and troughs (16, 18), (Fig. 2, not shown), and (22, 24) on the rotated mandrel (10) and on the roller (20) may also be of regular undulating shape to form a sinuous parallel sided gap therebetween when brought together. When a greater number of troughs are required, a mandrel with a greater number of ribs and troughs may be used with a similarly configured roller or a roller with fewer registering troughs may be made to approach the mandrel more than once over adjoining portions thereof. The mandrel, if long, may be supported at both ends. The mandrel carrying the tube may alternatively be freely rotatable and be made to approach a rotated roller; the mandrel and roller may also both be rotated. In an alternative embodiment (Fig. 3, not shown), a rotated mandrel (10) provided with a plurality of ribs (16) and troughs (18) is in succession engaged by a plurality of freely rotatable rollers (36), each having a single disclike rib (38), which are each mounted on a separate push-rod (42) actuated in succession towards the mandrel by a cam-shaft (48) whereby the tube (30) is gradually drawn into the troughs to avoid excessive thinning of the tube wall; the rollers (36) could alternatively be displaced by air cylinders sequenced by a timing device. The convoluted tubes are suitable for connection between stationary and movable objects, e.g. for motor car radiators, The forming member in the displaceable mounting may also be displaceable along its own axis; freely rotatable rollers may also be provided to move towards the mandrel outwardly of the end ribs thereof to form completely convexly shaped elements about the end ribs.

Title: Improvements in Electrical Weighing Apparatus
Inventor: INSHAW MICHAEL WILLIAM
IPC: D07B3/00
Filed: 1965-09-15
Abstract: 1,154,911. Measuring weight electrically; voltage measurement. W. & T. AVERY Ltd. Sept.13, 1966 [Sept. 15, 1965], No.39300/65. Headings G1N and G1U. In an electrical weighing apparatus, the weight indicator, comprising two relatively movable parts, is provided at either end of one part with two range change actuating means for actuation by the second part when it moves beyond the limits of the indicator, the actuating means being connected to a relay system which changes the relationship between the weight indication and the electrical output from the weight sensor. As described, the output from a strain gauge load cell bridge 12 is compared with the voltage from a potentiometer 15 and fed via an error amplifier 11 to a servomotor 10 coupled to the slider 13 of the potentiometer. The slider is connected to the pointer 18 of a meter which moves over a fixed scale 17 and which closes one of two pairs of contacts 16, 19, arranged at either end of the scale, if the weight to be measured does not lie within the range of weights indicated by the scale. Closing of one of the pairs of contacts causes a control circuit to operate the appropriate one of a number of relays RL1-RL6 controlling switches RL1/1-RL1/6 to include or remove resistors in or from the load cell circuit to reduce or increase the voltage from this circuit and to thereby change the range of the scale 17. The control circuit also causes different numerals to be displayed on the meter by changing the illumination of neon digitating tubes dependent on the range of the scale in use. Predetermined time delays may be incorporated in the control circuit so that the switches RL1/1- RL6/1 are not operated merely because the pointer is temporarily swung off the end of the scale.
