Abstract: 1,168,760. Continuous emulsion polymerization. UNIROYAL Inc. 24 Sept., 1968 [16 Oct., 1967], No. 45348/68. Heading C3P. Monomers are continuously polymerized in aq. emulsion by continuously feeding a portion of the total monomers and the whole amount of emulsifier used to a first reactor together with water and polymerization catalyst, where the mixture is retained while partial polymerization takes place and is then continuously withdrawn and fed into a second reactor at a rate equal to the feed rate into the first reactor, the remainder of the monomer is fed directly to the second reactor where the resulting mixture is retained to allow a desired degree of polymerization to take place, and the resulting latex is continuously withdrawn from the second reactor at a rate equal to the total feed rate into the second reactor. In the example a mixture of styrene and acrylonitrile was polymerized in an aq. mixture of sodium rosin soaps, potassium persulphate and mixed tert. mercaptans. The Figure illustrates an apparatus used in the above process, wherein 10 and 11 are the first and second reactors and 30 is a holding or storage tank where adiabatic polymerization can occur.

Title: Charge transfer circuits
IPC: H04N5/217
Filed: 1972-10-03
Abstract: 1395569 Television, active delays RCA CORPORATION 3 Oct 1972 [4 Oct 1971] 45514/72 Headings H4F and H3U In a charge transfer circuit which employs a plurality of charge storage elements (e.g. capacitors 24, 25, 26, Fig. 2), arranged in a delay line configuration and operative to transfer charge from one element to the next under the control of differently phased clock signals (e.g. A and B clock signals of opposite phase), to obtain an output signal free of transitions due to the clock signals (i.e. an output signal which is not serrated at the clock signal frequency), a summing circuit 30 is arranged to sum the stored signals on a sequence of the storage elements (e.g. 25 and 26) corresponding to the number of differently phased clock signals so that the serrations due to the clock signals are "filled in" by repeating each stored signal. As shown the charge transfer (or bucket brigade) circuit includes MOSFET devices 20, 21, 22 and 23, and although shown as a delay line, these devices may be photo-sensitive thus converting the circuit into a sensing array, a plurality of such sensing arrays in parallel (Fig. 1, not shown), comprising an image pickup. Although the photo-sensitive elements may be photo-diodes, photo-transistors or photoconductors, photo-diodes are preferred since a reverse biased diode already exists in an integrated MOS structure. A displayed video signal produced by such image pick-up would, without the summing circuit 30, have a series of vertical bars corresponding to the serrations produced by the clock signals. A delay line operating by means of a current sampling technique is described (Fig. 4, not shown) and one operating with three phase clocking signals is described with reference to Figs. 5 and 6 (not shown) in which the circuit comprises an image pickup array.

Title: A method of producing layers, sheet or films of rubber and/or plastics
Inventor: HOLT JACK
IPC: B29C48/91
Filed: 1967-10-10
Abstract: 1,240,653. Coated sheet material. DURIE & MILLER (HOLDINGS) Ltd. 9 Oct., 1968 [10 Oct., 1967], No. 46314/67. Heading B2E. Rubber and/or plastics layer, sheet or film is produced by coating a substrate with a foam composition comprising the rubber and/ or plastics, gelling the coating to a form-stable state, drying or substantially drying the coating and then subjecting the entire coating to pressure to collapse the foam to form a substantially solid sheet. The rubber may be a natural or synthetic rubber and the foaming can be carried out either by mechanical means or chemical means or both. The substrate may be a plate or endless belt from which the finished sheet is to be removed, or may be a textile or other substrate which is to be coated with a sheet of rubber or plastics. The foam may be crushed by pressing through calender rollers which may be plain or patterned. After crushing the foam may be heated to a temperature sufficiently high to cure the rubber or plastics. In an Example, a latex comprising styrene-butadiene rubber, carboxylated styrenebutadiene rubber, natural rubber, potassium oleate, sulphur, accelerator, antioxidant, pigment, foam stabilizer and mineral filler is mechanically foamed, chilling agents blended into the foam, and the foam then sprayed onto a fabric substrate and passed beneath a bank of infra-red heaters which gelled the foam. The gelled foam is then passed into a heated oven for drying, and between calender rollers for crushing and finally through a second heated oven for final curing. The coated fabric can be taken off the calender rollers in an uncured state so that it can be cured in situ during the main fracture of end product.

Abstract: 1,025,892. Slide projectors. VOIGTLANDER A.G. Dec. 11,1962 [Dec. 11,1961], No. 46817/62. Headings G2E and G2J. [Also in Division G1] The adjustable iris diaphragm for the projection objective of a slide or cine projector is carried by a mount 3 separate from the objective mount 4 and longitudinally displaceable in the housing 1, the diaphragm being mounted directly behind the rear lens of the objective such that during longitudinal displacement of the objective mount 4, the relative positions of the diaphragm and mount 4 are unchanged. Iris mount 3 is spring urged against the rear face of objective mount 4, and outer iris ring 13 is controlled by stud 9 which projects through and moves longitudinally and laterally in slot 8 formed in support 2. Cylindrical iris adjusting member 18 may rotate on support 2 but is fixed longitudinally thereon by the engagement of screw 21 with annular slot 23. The end of stud 9 enters a narrow slot 24 in member 18 and is therefore allowed longitudinal movement without changing the iris setting as the objective is moved in focusing. The objective is focused by rotation of knurled ring 4a and the engagement of screw 6 in helical slot 7. This system allows interchangeability of the objectives. In a modification, focusing is by simple longitudinal non-rotating movement of the objective, a set screw in support 2 engaging a longitudinal slot in lens mount 4. Here the iris mounting is integral with a mount 30 in which the lens mount 4 can be moved and then locked by a set screw. In an automatic form, the construction is as in Fig. 1 but has no external control for member 18 which is here rotated by means of a gear ring engaged by a motor-driven pinion. The motor is driven in either direction according to the density of the transparency to be projected, the density being sensed by partially reflecting the transmitted light on to a photo-cell which actuates the motor through a bridge circuit as in Fig. 3 (not shown). Alternatively, the iris setting may be internally controlled by mechanical means associated with each transparency and preset according to its density.
