Title: Insulated electrical conductor
IPC: H01B3/10
Filed: 1971-05-27
Abstract: 1342426 Coils for dynamo-electric machines ALLMANNA SVENSKA ELEKTRISKA AB 27 May 1971 [5 June 1970] 17465/71 Heading H2A [Also in Divisions H1 and H5] A varnish-insulated electrical conductor, for use in a coil of a dynamo-electric machine, is at least partly surrounded by a corona-resistant layer comprising one or two insulating tapes 13, 14 attached to the layer of varnish 11 and running in the longitudinal direction of the conductor. The tape is folded around the conductor, and several such conductors are then bundled together and surrounded by further insulation 25 to form the complete coil, which is placed in a core slot 38. Gaps, if any, between the edges of the tape(s) surrounding each conductor are arranged to overly those sides of the conductor which, in the assembled coil, face adjacent conductors. The corona-resistant tape 13, 14 comprises either (i) mica or glass flakes alone, or (ii) a mixture of such flakes with a linear polymer and/or fibres of cellulose and glass. The tape may be strengthened by (i) applying a glass fibre cloth to one side of the tape; (ii) impregnating the tape with a flexible resin; or (iii) applying a polymer film 26 to the outside of the tape. A resinous binder secures the tape 13, 14 to the varnish 11 and (when used) the film (iii) to the tape. The further insulation 25 surrounding the whole conductor bundle comprises: (i) tape wrapped around the bundle and formed of mica flakes on a paper or glass-cloth carrier, the tape either carrying or being subsequently impregnated with asphalt or an epoxy or polyester resin; or (ii) silicone rubber applied in tape or paste form. The further insulation may itself be wrapped in PTFE tape. Lists of the varnishes, polymers, resins, etc. that may be used are given.

Movement in the opposite direction allows fluid to return. Sleeve 50 is separated from the outer part 18 of the grip by resilient blocks 52, 54 which cut down vibration and heat transfer to the operator's hand.

Title: Device for killing whales and other animals by electric current
IPC: F42B30/14
Filed: 1930-06-11
Abstract: 352,678. Electrocuting whales. FROISLAND, A., 6, Inkognitogaten, Oslo, Norway. June 11, 1930, No. 17914, [Class 48.] Harpoons for electrocuting whales comprise a pointed cap 5 which carries a coiled electric conductor 7 and a body portion 1 which is provided with pivoted hooks 2, 3. The cap 5 is adapted to penetrate deep into the whale, while the body portion 1 is prevented from penetrating deeply by the hooks 2, 3. The killing current passes to the cap 5 through the conductors 12, 7 and thence back through the whale to the body portions 1 which is connected to the return conductor 11 by a contact 8. To provide a time interval between the hitting of the whale and the application of the killing current, a conductor 11 is connected to the body and to a contact 9 on the hook 3 and a conductor 12 is connected to the cap 5 through the conductor 7 and to a contact 10 on the hook 2. Before the harpoon penetrates the whale, contact 9, 10 is closed and a weak current passes from a battery 27 to energize a magnet 17 which supports a weight 25. On the harpoon entering the whale the hooks 2, 3 swing out and break contact 9, 10. The consequent de-energization of the magnet causes the weight 25 to fall and rock a lever 24 which breaks a contact 15, 16 in the weak current circuit and connects leads 20, 21 to heavy current leads 22, 23. The interval before the completion of the heavy current circuit can be varied by the fall of the weight 25.

Abstract: 315,971. Sarason, D. June 22, 1928. Addition to 278,498. No Patent granted (Sealing fee not paid). Heating and cooling appliances.-In a heating and cooling appliance for treating the vagina in which a thin rubber bladder b is inserted in the part to be treated and hot or cold water is then forced into the bladder from a water bag a, the neck b<1> of the bladder b is thickened so that it is held securely on a thick olive c<1> provided on a connection piece. The thickening may be obtained by dipping the neck into a rubber solution and allowing it to dry, the operations being repeated a number of times. A tube h for the introduction of the bladder b into the part to be treated and a smaller olive c<2> inserted into the end of a flexible tube i extending from the bag a are also provided on the extension piece. A clamp k or a cock on the tube i or on the olive c', serves to cut off the connection between the bag a and the bladder b.

Abstract: 1523429 Fuel injection pumps STANADYNE Inc 2 May 1977 [21 May 1976] 18289/77 Heading F1A [ Also in Division G3] In a fuel injection pump in which the injection timing is automatically controlled by a piston 46 subjected to engine speed dependent fluid pressure in a chamber 50 under the control of a servovalve piston 80, during starting the servovalve piston 80 is closed and the timing is advanced by the fluidpressure communicated to the chamber 50 through passages 54, 56, 58, 98, 100, 102, 60. Once a predetermined speed is reached after start-up a valve 92 is displaced by the fluid-pressure in a chamber 90 to a position which cuts off communication between passages 98, 102 whereby fluid in the chamber 50 can bleed away through an orifice 73 and thus retard the timing. At a higher speed the pressure reaches a valve in a chamber 84 which is sufficient to displace the servopiston 80 and direct fluid to the chamber 50 through passages 56, 78, 110, 86, 108, 106, 100, 102, 60. The servopiston 80 is loaded by a spring 82 the compression thereof being variable by a load sensing piston 114 actuated by pressure in a chamber 118 fed with fuel from a point downstream of a throttle valve (14, 16) in the feed line (116) to the pump working chamber.

Title: Improvements in compression rolling polymeric film
IPC: B29C69/02
Filed: 1961-05-19
Abstract: 982,703. Producing polymeric film. KODAK Ltd. May 19, 1961 [May 19, 1960], No. 18354/61. Drawings to Specification. Heading B5B. Transparent polymeric film (excepting poly- α-olefine film) is produced by forming a sheet of the polymeric material 1À05 to 10 times the desired thickness of the final film, and obtaining the final film from the sheet by passing the sheet between rollers under sufficient pressure to reduce the thickness of the sheet to the desired thickness, the surface of the film at the line of pressure being covered by a lubricant, which is defined as a liquid, a grease or a solid such as graphite or paraffin wax. Examples of lubricants that may be used are xylene, VMP naphtha, esters such as butyl acetate, alcohols such as butanol; ethers such as diethyl cellosolve, alcohol-ethers such as 2-ethoxyethanol, ketones such as methylisobutyl ketone, glycols such as ethylene and diethylene glycol, water with or without a wetting agent and low molecular weight polyethylene waxes. Paraffin wax, if used, may be in the form of an emulsion in a mixture of water and isopropanol, using " Aerosol OT " (an ester of a sulphonated dicarboxylic acid) as an emulsifying agent. A dilute aqueous solution of this agent alone may be used as a lubricant. The polymeric material of the film may be a polyester, such as polyethylene terephthalate, a polyamide, a polycarbonate, a chlorinated polyether, a polyacetal, a cellulose ester or a halogenated polyolefine such as polytetrafluoroethylene. The temperature of the pressure rollers depends upon the softening temperature of the polymer and for most polymers can be at room temperature, but it may be within the range of 40 to 300 C., depending upon the polymer. The polymer may first be formed by melt-extrusion or casting into a sheet having a thickness of 4 to 60 times that desired in the final film, and the sheet may then be stretched at 65 to 240 F. in a direction perpendicular to that in which the pressure rolling takes place to reduce the thickness by 100% to 500%. The sheet is then passed to the pressure rollers for its final reduction in thickness.
