Title: Image transfer element
IPC: G03F7/00
Filed: 1975-10-28
Abstract: The sheet consists of a thin, flexible, transparent support foil, a release agent layer located thereon and a light-sensitive layer on the release agent layer. The light-sensitive layer contains (a) one or more addition-polymerisable, olefinically unsaturated compounds having at least one terminal double bond, for example acrylates or methacrylates, (b) a photopolymerisation initiator forming free radicals and (c) a binder. After imagewise exposure and development, i.e. removal of not photopolymerised substance, this gives a "finished" transfer sheet, whose image elements can be transferred by rubbing and pressing from the back of the sheet to another substrate. The elements are detached at the release agent/support interface or release agent/element interface, or else in the release agent layer.

Abstract: 956,798. Magnetic switches. PHILCO CORPORATION. Dec. 29, 1960 [Dec. 29, 1959], No. 44590/60. Heading H2B. [Also in Division G3] A movable magnet which actuates a plurality of magnetic contact devices as it moves past them in turn is mounted on a resilient arm so that the attraction between the magnet and the armature of an operated contact device retains the magnet until sufficient force is applied to the other end of the arm to cause snap-action movement of the magnet to its next switching position. In Fig. 1, the arm 27 is part of a U-shaped ambient temperature compensated bi-metal surrounded by a heater 28 and secured at 25 to a fixing bracket 26. The magnet 21 moves along an arcuate path as the bi-metal 27 is heated and it attracts spring steel members 17 in turn, each member 17 having a contact 18 which engages a non-magnetic plate 15 which may be of copper or stainless steel or of plastic insulating material with printed circuit contacts and connections. In an alternative arrangement (Fig. 2, not shown), the arm is controlled by two spiral bi-metals and carries a horseshoe magnet. In Fig. 3, the resilient arm 62 is driven by a motor through reduction gearing 64 and the time of closure of the switch devices 69, 70, 73 ... 75, is controlled by the angular extent of their armatures (e.g. 68) and by the proximity to the path of the magnet (e.g. 72). The switch devices may be encased in a dust-free enclosure.

Abstract: 1,150,017. MHD power plant. CENTRAL ELECTRICITY GENERATING BOARD. 2 Oct., 1967 [7 Oct., 1966], No. 45005/66. Heading H2A. In an open-cycle MHD power plant wherein fossil fuel is burnt to provide combustion gases which are passed through a generating duct at sub-atmospheric pressure, the seed material is ionized before mixing with the combustion gases. The potassium or caesium seed material is fed in as a vapour, possibly with a small amount of carrier gas, at an inlet 25 and is ionized by an alternating or direct potential applied between electrodes 27 before being injected into the combustion gases through a nozzle 24. To minimize the decrease in ionization occurring as the seeded combustion gases pass through the generator duct 14 it is necessary to have a strong magnetic field and a low static gas pressure. For the latter reason, the combustion gases are passed through a convergent-divergent accelerating nozzle 13 to increase the velocity and reduce the pressure below atmospheric. The pressure is brought back to atmospheric by means of a convergent-divergent nozzle 20 and a compressor 22 before the gases are discharged at 23. The seed may be ionized by other means, e.g. an electron beam or thermal means such as an electric arc or a separate very high temperature combustion system.

The brush-holder comprises a tubular housing 1, of insulating material, having a rim 3, 4, of which the portion 4 is higher than the remainder, and has a slot 5. A brush 9 is slidably mounted in the housing 1, and is separated from a metal plate 7 by a compression spring 10. The plate 7 is retained by two projections 6 extending inwards from the rim 3, but it has two recesses in its edge so that by rotation the recesses may be aligned with the projections and the plate may be lifted past the projections. The plate 7 has a radially-projecting tag 11 which is frictionally gripped between the limbs of a bifurcated terminal 12, extending through the slot 5 and attached to a current supply wire 13. The slot 5 has a width only slightly greater than that of the terminal 12, and is located so that the plate 7 is locked when 11 and 12 are connected, so that the terminal 12, and hence the current supply, must be disconnected from the plate 7 before the plate can be removed from housing 1. It is thus impossible to remove plate 7 and brush 9 while current is flowing through them. As a further protection, a flexible insulating cap 14 is provided, having an extension 15 in which the terminal 12 is a tight fit. To gain access to the plate 7 (for renewal of brush 9), the left-hand side of cap 14 is raised until it is free of rim 3, and then the extension 15 is pulled to detach terminal 12 from tag 11. The liveterminal 12 remains inside cap 14. Reference has been directed by the Comptroller to Specification 958,198.
