Title: Production of electrical resistive elements
IPC: H01C17/00
Filed: 1973-06-27
Abstract: 1410876 Depositing carbon SIEMENS A G 27 June 1973 [20 Nov 1972] 30708/73 Heading C7F [Also in Division H1] A resistance element is formed by pyrolytically depositing a film of carbon from a reaction gas containing an unfluorinated carbon compound on to an insulating silicon-containing inorganic substrate which, immediately prior to or at the commencement of the deposition of the film, is etched by the thermal decomposition products of a fluorine-containing carbon compound. The carbonizing agent, which may be C3H8, C 7 H 16 , C 7 H 14  or isopropyl alcohol, may be fed to the reaction vessel at the same time as or after the etching agent, which may be CF4, C 5 F 10 , C 6 F 14  or C 7 F 14 . One or both of the agents may be initially in liquid form in which case they are evaporated from a storage vessel. Nitrogen may be used as a carrier gas. When the agents are supplied at the same time, the etching reaction can be caused to occur first by altering the temperature and/or the pressure of the reaction gas and, when liquids are being evaporated deficiencies in mixing, differing specific gravities and/or azeotropic distillation can be utilized. After deposition of the carbon film electric terminals are applied to its ends.

Title: Improvements relating to the production of metal castings
IPC: B22D7/04
Filed: 1938-10-26
Abstract: 520,598. Casting processes. BAILEY, R. W., METROPOLITAN-VICKERS ELECTRICAL CO., Ltd., and ENGLISH STEEL CORPORATION, Ltd. Oct. 26, 1938, No. 31004. [Class 83 (i)] Cores ; moulds ; casting composite articles.-In the casting of hollow articles, e.g., hollow steel ingots, segregation is reduced by cooling the core 3 internally by a removable solid body 8 arranged therein, and this body when hot is replaced by a cool body of the same or a different shape. Cooling may be assisted by the passage of air or other fluid through the core and this may be assisted by a jet of air, steam, &c. at 6. The core may include a shell 21, Fig. 2, arranged about the hollow core 3 to which its lower edge may be welded. The shell 21 may be longitudinally corrugated and is thin enough to soften, after solidifying a layer of the cast metal, or otherwise yield easily as the ingot shrinks. The shell may become bonded to the casting or this may be prevented by a suitable coating. The space 29, between the shell 21 and core 3, or 59, between the core and body 8, may be filled, progressively or otherwise, with lead or other metal, alloy, or salt having a low melting-point, e.g., by means of an electrically heated pipe 32, a melting pot 30, and compressed gas in a container 35. Whether the space 59 is filled with lead &c. or not its radial dimension may vary at different points along the length of the core to vary the rate of cooling. An insulating sleeve 28, Fig. 2, may be arranged in a recess in the core to reduce the rate of cooling in the head 4 and an insert sleeve 27, to be cast into the head of the ingot, may be placed on the upper end of the core. The shell 21 may comprise a thin sheet wrapped so that its sides overlap and tacked or joined, e.g., by welding. Specification 360,980, is referred to.

Title: Nuclear power plant with co cooling
IPC: G21D5/06
Filed: 1967-07-05
Abstract: 1,130,740. Nuclear power plant. SIEMENS A.G. 5 July, 1967 [9 July, 1966], No. 31060/67. Heading G6C. In a nuclear reactor power plant, the gas, CO 2 , flows in a closed path through the reactor, compressor and turbine, the latter driving both the compressor and the generator. In order to reduce the space requirements of the compressor, the gas density is raised, by cooling, prior to entry to the compressor. The cooling is effected in the primary of a regenerative heatexchanger followed by a condenser. After compression, the gas flows through the secondary of the exchanger where it is heated and then admitted to the turbine. The gas returns to the reactor from the turbine exhaust. A heavy water moderated reactor or a fast breeder may be used and in the latter case xenon poisoning phenomena do not restrict the speed of plant output regulation. The containment enclosure C surrounds the pressure vessel DK in which the reactor R, heat-exchanger W and condenser K are mounted. The turbine T, compressor V and fuel element decay tank B are disposed between C and DK.

A flame-resistant craft, e.g. a ship's lifeboat, having personnel accommodation space totally covered by a canopy adapted to be sealed to the structure of the craft in such a way as to substantially prevent the ingress of ambient atmosphere into the space, has means for continuously flooding with cooling liquid both the canopy and the entire skin of the body or hull, at least above the water line of the latter. In one embodiment the boat has a canopy of flexible waterproof material supported by a ridge pole 6 and columns 9 which also serve as conduits to supply water to the sprinklers 7, carried by the pole 6, and provided to flood the outer surface of the canopy and the hull. The water is drawn by a pump 8 from below the water surface through an intake 11 and passed to the members 6 and 9 as well as sparge pipes 10, at the bow and stern, which flood the outer surfaces of those parts of the vessel. The canopy 5 is secured to the boat by e.g., quick release catches. The canopy may be of rigid sheet material, e.g. steel, aluminium resin-bonded glass fibre, which may be lined with heat insulating material and which has sealable access openings. The canopy and hull may be formed with inner and outer skins defining water jackets through which water may be pumped to be released through vents where often it floods the outer surface of the boat.

Abstract: 1482186 Labelling MONARCH MARKING SYSTEMS Inc 15 July 1974 [18 July 1973 14 Sept 1973 5 June 1974 (3)] 31327/74 Heading B8F In apparatus for printing and applying pressure sensitive labels carried on a web of supporting material, a print head, which moves into and out of printing co-operation with a platen before web feed, is driven by a lever secured to one of a pair of meshing gears, the other of the pair being driven. As shown, a hand held label applicator comprises plastics frame parts 52, 53, 54 and a metal subframe 55. The label supply spool is mounted on spring hub 113 on the subframe, and the supply web 30 passes under roller 117 which brakes the web by pressing it against abutment 118 when the print head 63 is in its rearmost position, round roller 71, over platen 69, round delaminator edge 70 to release a label 36, and the supporting web 32 then passes round roller 72, roller 64a and the web feed roller 64, and over discharge guide 77. Roller 64 has teeth 64<SP>1</SP> which rupture web 32 at places of weakness to engage and drive the web, roller 64a being spring biased to hold the web against the roller where the rupturing occurs. A printing and applying cycle is caused by operation of a finger lever 81 pivoted on shaft 78 and having a gear sector 82 meshing with gear 66 mounted coaxially with the feed wheel 64 and formed with a lever 67 having a pin-and-slot coupling 87, 89 with the print head, whereby actuation of lever 81 causes printing of a label on platen 69 and releases braking roller 117. The return stroke of levers 81 effected by spring box 82<SP>1</SP> operates the feed wheel through pawl 83 and ratchet wheel 65. The print head is mounted by tracks 92, 93, ball strips 96, 97, and tracks 94, 95 secured in a window in subframe 55. Actuation of the head causes an inking roll 107 to move across the type faces 98, 99. The feed roll periphery is toothed so as to reduce the surface contacting the supporting web which may bear adhesive remnants, and may have a silicone release agent coating. For loading the applicator, roll 64a may be moved to a position where its biasing spring holds it off feed roll 64, and lever 81 is partially actuated to release braking roller 117.
