Title: Improvements in or relating to television cameras and the like
Inventor: WHITE NORMAN WILLIAM
IPC: H04N5/235
Filed: 1962-06-20
Abstract: 974,441. Cathode-ray tube circuits; television; automatic gain control. MARCONI INSTRUMENTS Ltd. Feb. 21, 1963 [June 20, 1962], No. 23737/62. Headings H3Q, H4F and H4T. The intensity of the scanning beam of a charge-storage type image signal generating tube is maintained at the optimum value for the brightness of the subject " viewed " by controlling its intensity in accordance with a signal dependent on the maximum peak video output signal integrated over a period of time which is long relative to the time required to scan one storage element of the target. The invention is concerned with eliminating the " peeling " effect (i.e. loss of video information at and near bright areas) when image tubes of the charge storage type are required to " view " subjects of widely differing brightness levels such as are encountered in closed circuit industrial television systems and particularly in systems in which the subject is an X-ray screen presentation " viewed " either directly or via an intermediate image intensifier tube. Fig. 3 shows the arrangement utilized for carrying out the invention in which a peak-to-peak rectifier and integrating circuit 5 fed with the video output of tube 1 via amplifier 2 and a manuallyadjustable variable gain amplifier 4 supplies a signal via a cathode-follower 6 which effectively amplitude modulates line frequency synchronizing pulses fed to the grid of valve 7 to provide a control signal which, after peak-to-peak rectification in 11 operates to vary the intensity of the scanning beam of tube 1. The circuit 5 has a time constant equal to the time taken to scan 10 to 20 fields and the whole arrangement is such that the gain around the loop exceeds unity for that part of the tube characteristic relating output signal to beam intensity (see Fig. 1), which is " below " the optimum operating point X in the knee K but is less than unity over the part adjacent to and beyond the knee. The control signal fed to rectifier 11 is also utilized after rectification in 12 as an automatic gain control signal for amplifier 3 feeding the picture reproducing tube. Additionally, a shaping circuit comprising the elements 9, 10, 13 is provided to modify the control signal in order to compensate for the non-linear relationship, as shown by the full line curve in Fig. 2, between the tube output signal RO and the brightness of the subject RI when the tube operates with optimum beam current for different values of brightness. The effect of the shaping circuit produces a control signal characteristic following that shown by the broken line graph and therefore results in an overall linear response.

Copper or nickel phthalocyanine pigments are prepared by reacting a 1,3-diimino-isoindoline with a copper or nickel salt in a polyhydric alcohol in the presence of an optionally substituted benzyl cyanide at a temperature below 190‹ C. The benzyl cyanide may be a 3- or 4- chloro, 3- or 4-bromo or 3- or 4-nitro derivative and is added in an amount of from 3-10% by weight based on the amount of diimino-isoindoline. The copper or nickel salt is advantageously the chloride, bromide or sulphate or a salt of an aliphatic or aromatic mono- or dicarboxylic acid e.g. acetate, phthalate or oxalate. The amount of diimino-isoindoline to metal salt is in the molar ratio of 4À5 : 1 to 3À5; 1. Suitable polyhydric alcohols are e.g. ethylene glycol or glycerol and a single solvent or a mixture of such solvents may be employed. For copper-phthalocyanine pigments the reaction is carried out at 110-140‹ C. and for nickel pigments at 140- 180‹ C. The produced pigments are stable to aromatic solvents and may be used for pigmenting lacquers, inks and natural, regenerated or artificial fibres on which they give blue shades.

Title: Container and safety closure construction
IPC: B65D50/04
Filed: 1971-04-19
Abstract: 1344371 Safety closures EYELET SPECIALTY CO 19 April 1971 [10 March 1970] 24366/71 Heading B8T A safety closure consists of a screw cap 17, which engages with the thread 12 on a bottle neck, and a sleeve 21, e.g. of a resilient plastics material, in which are slits 26 enabling the sleeve to be radially deformed. If the unscrewing of the cap is attempted, the interengagement of flange 19 with abutments 24 and of abutment 22 with bead 14 will prevent the cap from being completely removed. If, however, while the cap is fully screwed down, the sleeve is depressed (using flange 25), the camming engagement of the sleeve portion 30 with the frusto-conical portion of the bottle neck moves the abutments 24 radially outwards, and hence no engagement takes place between the flange 19 and abutments 24 when the cap is unscrewed, so that removal of the cap is possible. Optionally the cap 17 may have a seal (34), Figs. 7 and 8 (not shown), such that due to the resilience of the metal feet (37) the seal is effective for all positions of the cap possible without the sleeve being depressed. Alternatively the sleeve may serve the same purpose by having a telescoping action, Fig. 9 (not shown).
