Abstract: 1,200,479. Ornamenting. G. RITZERFELD. 6 Dec., 1967 [7 Dec., 1966], No. 55510/67. Heading B6G. [Also in Division B2] Manuscripts, printed matter, hectographic copies are mounted with foils carrying a layer of a thermoplastic adhesive to which is added an ultra-violet-absorber containing substituted benzophenone. The foil may be of heat-insensitive polyester. In Fig. 3 foil 15 carrying a layer 14 consisting of heat sealing adhesive and ultra-violet-absorber is placed together with the original matter 12 e.g. manuscript and its inscription 13 in a mounting holder 1 comprising a card 3 carrying on one side a silicone layer 2 and an infra-red-transparent gauze 4 fastened to it. No firm adhesion of the synthetic foil 15 through its heat-sealing adhesive to card 3 is possible when the synthetic foil 15 is not accurately registered with the original material 12 since card 3 carries the silicone layer 2. In Fig. 2 (not shown), a mounting holder comprises a card provided on one side with a layer of heat sealing adhesive, on which lies a sheet of paper coated with silicone layer and securely attached on its uncoated side to the layer of heat-sealing adhesive. An infra-red-transparent synthetic foil fastened to the paper serves during the mounting operation to cover the material to be mounted.

Abstract: 1323600 Discharge tubes EMIL HAEFELY & CIE AG 27 Nov 1970 [28 Nov 1969] 56379/70 Heading H1D Apparatus for removal of components from a high or low pressure encapsulated space comprises an airlock connected to the space by a removable pressure-tight seal and provided with a manipulating means extending into the airlock and operable from the surroundings. The airlock 6<SP>1</SP> is attached by screws 55 to a sealing lid 3 of the high pressure vessel 1 of an electron accelerator in which the rotatable cathode 29 is located in an evacuated cathode space 27 above the accelerator tube 31. A shutter 7 which can be opened and swung aside by the mechanism 8 allows access into the pressure vessel 1 for the manipulator 10 which is sealed to the airlock walls by a seal 11 permitting it to be thrust into the vessel 1, for example, to remove the cathode inserts 29 without disturbing the vacuum in the accelerator tube 31. The manipulator attachment portion 12 is attached to the head 48 of an operating column 33 such that movement of the column simultaneously closes valve 32 to isolate the cathode space 27, removes the cathode leads 44, disconnects the motor 37 which rotates the cathode, and the arm 49 moves to allow access to the attachment head 47 of a second operating column 52. The manipulator is then attached to the column 52, movement of which equalizes the pressures in the cathode space and the pressure vessel through valve 46 and simultaneously allows access of the manipulator to a third connected head 54. Bolts securing the cathode enclosure walls 36 to the accelerator tube are then removed and after attaching the manipulator to the head 54 the cathode and surrounding walls 36 can be withdrawn into the airlock. After closing the shutter 7 and equalizing the pressure inside the airlock with that of the surrounding atmosphere, the airlock can be removed by removing screws 55. In replacing the cathode, the airlock is first evacuated by pump 21, then the pressure inside is equalized with that in pressure vessel 1 by opening the valve 26 and then the cathode enclosure is attached to the accelerator tube. The cathode space 27 is evacuated by pump 21 which is connected by the flexible hose 15, a central bore 14 in the manipulator 10 and the bore 53 through the shaft of valve 46 to which the manipulator is attached. Movement of the manipulator is  observed through a viewing glass 23. The  apparatus may be used in other high voltage installations and more than one manipulator may be provided.

In operation the housing 11, 12 is secured to the conduit 16 and held axially by clamps 101 and rods 102, the cutter 87 being in the housing. The actuator assembly together with the housing 46 is assembled on the housing 11, 12 the cutter 87 being connected to the block 77 during this operation. The actuator means is then operated to force the cutter through the conduit 16 to shear out a section thereof and deposit it in the bottom half of the housing 11. The plug 82 is then axially aligned with the conduit and pressure fluid is admitted to the recess 81 so as to force the plug 82 into sealing contact with the end of the conduit. After repairs or other operations have been done on the conduit the plug 82 is released and the actuator operated so as to retract the cutter until it contacts the shoulder 97 of the aperture 47 to sealingly close the aperture through seal 99. The cutter is then locked in this position by screws 100 and the actuator assembly is removed the pins 92, 93 being withdrawn during this process. A cover (Fig. 5, not shown) can finally be secured over the aperture 47.

Abstract: 1463082 Liquid metal slip ring attachments GENERAL ELECTRIC CO Ltd 17 Dec 1974 [19 Dec 1973] 58730/73 Heading H2A In a dynamoelectric machine slip ring arrangement wherein a first annular member on the machine rotor is operationally in contact with a second non-rotating annular member via liquid metal, the second member is supported independently of the rotor from a stationary support via a linear bearing and is coupled to the rotor so as to move axially with the first member during any axial movement of the rotor. In the arrangement shown, currents are transferred between a set of non-rotating rings 10 and a set of rotating rings 9 on a rotor shaft 7 by means of rings of conductive liquid (not illustrated) centrifugally formed in annular grooves 18 in rings 10. The rings 10 are mounted on axially displaceable metal rods 12 in linear bearings 13 by means of insulating bodies 11 fixed on the rods 12, and a thrust collar 16 on the rotor shaft 7 co-operates with one of the bodies 11 to move the rings 10 the same axial amount as the rings 9 whenever the shaft 7 itself is displaced. Springs 17 keep the collar 16 in contact with the co-operating body 11, and seals 19, e.g. of resilient phosphor bronze prevent escape of liquid metal vapour. The rings 9, 10 may be of molybdenum, iron or stainless steel, and the liquid metal may be an indium/gallium alloy containing 23% indium. The surrounding space is pressurized with a gas such as hydrogen, helium, argon or sulphur hexafluoride. In the arrangement of Fig. 3 (not shown), a liquid metal ring (22) on the interior of a rotary ring (21) provides contact between the rotary ring (21) and a non- rotating ring (23). In the arrangement of Figs. 4, 5 (not shown), non-rotating rings (29) on axially displaceable rods (32) are axially displaced the same amount as rotary rings (24) on a shaft (7) (when the shaft is displaced) through the co-operation between annular permanent magnets and pole pieces (39, 40) on the rods (32) and yoke members (41) on the shaft. Ducts (47, 48) allow circulation of liquid metal and gas in operation. The various contact systems may be used in an A.C. generator (Fig. 1, not shown), having a superconducting stator field winding (1).
