Title: Colour television cameras
IPC: H04N9/077
Filed: 1971-03-24
Abstract: 1386595 Colour television camera EMI Ltd 13 March 1972 [24 March 1971] 7861/71 Heading H4F [Also in Division H1] The spatial colour encoding filter of a single pick-up tube type colour television camera comprises a repeating series of red, green and blue filter strips with an opaque strip disposed between adjacent colour filter strips, all of the colour and opaque strips having the same width. Alternatively the opaque strips may be formed on a separate filter or on the front of the pick-up tube, or the opaque strips may be simulated in manufacture of the pick-up tube, its target being formed with alternate strips of responsive and non-response material, or responsive and no material. The strips are preferably arranged at right angles to the scanning lines of the pick-up tube, although they may be arranged at an angle thereto, e.g. 45 degrees. The video output signal of the pick-up tube has a reference frequency, and the red, green and blue video signals are derived therefrom by dividing this reference frequency by three and using it to sample the output signal directly and via 120 degrees and 240 degrees phase shifters. The encoding filter may include coding strips at its edge for generating colour phase identifying signals at the beginning of each scanned line. The filter may be inside the pick-up tube or it may be coupled to the pick-up tube by fibre optics or a relay lens. A second pick-up tube may be provided for producing a luminance signal.

Abstract: 807,597. Ice making. LOCATOR, S. A. March 11, 1957 [March 29, 1956], No 7978/57. Class 29 An ice cream freezer comprises a cream tank 2 and a freezing cylinder 14, equipped with a refrigerating device 33 and a rotatable mixing member 17 axially displaceable in the cylinder, and is characterized by the tank 2 being housed above the cylinder 14 and having an outlet valve 4 equipped with a control member 5 operable to deliver a predetermined amount of cream from the tank, and by having a mould 36, with which the cylinder communicates, for a single portion of ice cream. The mixer 17 occupies substantially the whole cross-section area of cylinder 14 and is keyed to a shaft 15 rotated by a motor driven spindle 12. The shaft 15 is fixed longitudinally relative to a bearing 20 supported on trunnions 22 attached to arms 22 carried by a foot 25 sliding in a channel member 26 located parallel to the spindle 12. The foot 25 carries a rod 40 and is connected to a lever 29. On pulling the lever the foot 25 is moved along a channel 26 against a spring 31, and thus mixer 17 is moved along cylinder 14. The rod 40 first actuates switches 6 and 9, opening valve 4 and energizing the motor, then switch 7 closing valve 4 and finally switch 10 de-energizing the motor when the mixer reaches the end of cylinder 14 the frozen cream is forced into mould 36. The operation of the freezer may be made automatic and several tanks and freezing cylinders may be mounted in parallel for cooling by a single installation.

Title: Improvements in antioxidants
IPC: C08K5/18
Filed: 1943-05-20
Abstract: Rubber and allied gums and turpentine are preserved from oxidation by the incorporation therewith of a cycloalkoxy-diarylamine having at least four carbon atoms in the closed ring of the cycloalkoxy group. The compounds are prepared by the interaction of the corresponding hydroxy-diarylamine with a cycloalkoxy halide.  The anti-oxidants have the general formula R-NH-R1-O-Y, where R is aryl or substituted aryl, R1 is arylene, and Y is a cycloalkoxy group.  Examples of the method of preparation of the anti-oxidants which are stated to be of general application are: (1) the preparation of 4-cyclohexyloxy-diphenylamine by refluxing a solution of 4-hydroxy-diphenylamine in n-amyl alcohol containing dissolved metallic sodium for 24 hours with cyclohexyl chloride; (2) the preparation of 4-cyclohexyloxy-phenyl beta naphthylamine by refluxing cyclohexyl chloride with 4-hydroxy-phenyl beta naphthylamine under the same conditions as example (1).  Examples of the efficiency of the antioxidants are given with respect to the use of the compounds prepared in examples (1) and (2) above in a rubber mix and in turpentine, using the method of Howland and Hart.ALSO:Rubber and allied gums are preserved from oxidation by the incorporation therewith of a cycloalkoxy-diarylamine having at least four carbon atoms in the closed ring of the cycloalkoxy group.

Abstract: 1,175,151. Multiple fastenings. G. K. N. SANKEY (PTY) Ltd. 20 Feb., 1967 [21 Feb., 1966], No. 8014/67. Heading E2A. A filing cabinet has a plurality of drawers arranged above one another, each drawer being provided with a fastening mechanism, means being provided interconnecting the fastening mechanisms, the arrangement being such that the opening of any one drawer operates each of the interconnected fastening mechanisms to fasten the unopened drawers against being opened. In the construction shown the interconnecting means consists of a bar 12 slidable vertically in the cabinet and rigidly attached to the bar 12 is a number of locking plates 13 one for each drawer, the plates 13 each being provided with a slot 14 for the reception of a respective pin 9. For each drawer the pin 9 is carried by a plate 4 which is attached to the filing cabinet by a pivot 5 and which has a slot which coacts with a pin 3 carried by the drawer; the plate 4 is biassed by a spring 8 which is connected between the pin 9 and an anchoring point 10 on the filing cabinet and the arrangement is such that the spring holds the bolt in alternative positions, the pin 3 entering the slot during opening and closing movement of the drawer to move the plate 4 between its two positions; when the drawer is closed the plate 4 holds the drawer in the closed position by the engagement of the pin 3 with the plate 4 but pulling of the drawer pivots the plate 4 to. release it; the movement of the plate 4 causes .the pin 9 to describe an arc and the opening movement of the drawer causes the pin 9 to engage the upper wall of a slot 14 in the respective plate 13 so raising the plate 13 for the other drawers the other plates 13 are then positioned so that a blocking surface 15 moves into the path of the pin 9 so that the other drawers cannot be opened. The bar 12 is also connected to a lock and key mechanism which can raise it further than it is raised by the pin 9 so that all the drawers. are locked by a single key in the closed position.
