Title: Emulsified propellant compositions for foamed structures such as applicator pads and process
IPC: A61K8/81
Filed: 1972-07-24
Abstract: 1384267 Foamed polymeric cleansing pads BRISTOL MYERS CO 24 July 1972 [28 July 1971] 34483/72 Heading C5D [Also in Division C3] Cleansing compositions consist of a detergent within a polymeric foamed structure, e.g. an applicator pad, which is made from an oil-inwater emulsion comprising a continuous phase of water containing a foam-stabilizing agent and dispersed in the water, as a discontinuous phase, a solution of a film-forming synthetic polymer in a liquid propellant, i.e. a volatile organic compound boiling below 45‹ F. at atmospheric pressure and retained in the liquid phase at super-atmospheric pressure, and dispersed or dissolved in the emulsion a detergent which is deposited with the water phase in the cells and walls of the foamed structure produced when the propellant volatilizes and which can be removed from the cells of the structure. The emulsion can be formed into a foamed structure by expelling it from a closed container, e.g. an aerosol container, and volatilizing the propellant at atmospheric pressure and temperature so as to foam the synthetic polymer and form a foamed structure.  In Examples 1-11 cleansing pads were made by expelling from aerosol cans oil-in-water emulsions containing as the aqueous phase water with triethanolamine lauryl sulphate or polyoxyethylene lauryl ether and optionally isopropanol or ethyl alcohol and as the oil phase a solution of polymer (vinyl toluene-acrylate copolymer, polyvinyl acetate, cellulose acetate butyrate or polyisobutylmethacrylate and optionally oleyl alcohol) in propellant (trichlorofluoromethane dichlorodifluoromethane, 1- chloro-1,1-difluoroethane and/or 1,2-dichlorotetrafluoroethane).

Title: Improvements in or relating to the pressing of sheet metal or other material
Inventor: NORTH JOHN DUDLEY
IPC: B21D22/12
Filed: 1957-11-06
Abstract: 871,251. Hydraulic. presses. BOULTON PAUL AIRCRAFT Ltd. Nov. 5, 1958 [Nov. 6, 1957], No. 34573/57. Class 69 (2). [Also in Group XXII] An hydraulic system for operating a sheet metal working press includes an hydraulic ram 33 for reciprocating an upper pressure chamber 1 containing an elastic diaphragm 18, damper rams 17 for controlling the rate of descent of the chamber 1, a manually operable control valve 36 which supplies pressure fluid from an electrically driven pump assembly 57 via two check valves 43 and 44 to the ram cylinder and an hydraulic cylinder 32 for actuating locking means 29 for securing the chamber 1 to the lower platen 23 of the press which supports a die 24. The locking means are controlled by a valve 64 operated by a solenoid-actuated pilot valve 67 energized by a ram-operated limit switch 68 via a time-delay switch 70. The pressure chamber 1 is connected to a manifold 91 which communicates with a high-pressure solenoid-controlled switch-off valve 83 and thence via a conduit 71 through a medium pressure shut-off valve 75, actuated by a beam 11 on the ram 63, to tubular reservoirs 72. The reservoir assembly comprises two tubular members interconnected at their ends. At one end is arranged an air charging valve 98 and the other end houses a metal float 73 for sealing the conduit 71 from the pressure chamber 1 when the exit of fluid from the reservoir is completed. A second tubular reservoir 79 is arranged for injecting a supplementary supply of hydraulic fluid into the reservoir 72 when female tools 24 are being used. The pressure pump assembly 80 is of the spring-loaded swash plate type. An intensifier 84 is included in the system and manually operated valves 86 and 77 control the pressurization and intensification of the fluid in the chamber 1. In operation, when the chamber and lower die are brought together and the elastic diaphragm is distorted by engagement with the die the pressure inside the chamber rises and fluid is returned to the reservoirs 72. The chamber is pressurized by actuation of the control valve 77 and when a predetermined pressure is reached, e.g. 2000 p.s.i., a pressuresensitive switch operates a solenoid-controlled shut-off valve 83. If intensification of the pressure is required control valve 86 is operated to admit fluid pressure direct from the pump assembly to the intensifier 84, which supplies the required pressure fluid to the chamber to deform the workpiece.

Filed: 1922-12-20
Abstract: 212,008. British Thomson - Houston Co., Ltd., and Pollock, A. A. Dec. 20, 1922. Rotary transformers.-A machine for converting a variable voltage into a substantially constant voltage, more particularly for use on electric railways, comprises two armatures 1, 2 connected in series across the supply 7, the armature 2 having a magnetic circuit of low flux density, and the armature 1 a magnetic circuit of high flux density; the greater part of the variation in the supply voltage is taken up by the armature 2, so that the voltage of the armature 1 is approximately constant. If a voltage lower than that across the commutator 3 be required, an additional winding may be connected to a commutator 8. In the arrangement shown in Fig. 1 (Provisional), the field winding 6 is first excited at the full supply voltage, but as the arm of the rheostat 10 is moved to the right resistance is introduced and finally the field winding is excited from its own armature 2. Fig. 1 (Comp.) shows a set which can be started automatically without the rheostat, and in which the compounding coil 9 is placed in the supply circuit. A series starting coil 11 is arranged to be short-circuited by a contactor 12 which is normally held open by a spring, and closed, when the requisite voltage is reached, by a coil energized from the commutator 8. The winding 13 on the machine 2 acts in opposition to the field 6, and the combination produces a greater variation in the field strength. Compensating or commutating windings may also be employed.

Title: Improved dip coating process and apparatus
Inventor: BRESSERS LEOPOLD
IPC: B29C41/14
Filed: 1965-08-17
Abstract: 1,113,961. Coating by dipping. GLAVERBEL. 17 Aue.. 1965 [26 Aug., 1964; 25 May, 1965]. No. 35268/65. Headings B2K and B2L. In coating an object with liquid coating composition by dipping, the withdrawal of thc object is automatically controlled according to a speed/time programme either to give a uniform thickness of coating composition or a desired variation in thickness. The speed/ time programme can be established by one or more tests on a sample object or by continuous measurement or determination of the thickness of coating just above the bath surface as the object is withdrawn from the bath and, preferably, the programme includes a temporary reduction in speed over the period when the object first breaks the bath surface to avoid disturbance of the coating composition. The automatic control is preferably achieved by a hydraulic jack mechanism under the control of an optical or a magnetic or mechanical record. In the arrangement shown a sheet 13 e.g. of glass is supported above a dip tank I by cables 10 connected to hydraulic jack 6, a counter-weight 15 also being connected to jack 6. Movement of the jack 6 and hence the sheet 13, is achieved through hydraulic lines 21, 22 by pump 19 drawing and returning oil from and to tank 16 and through a reversing distributor 17. A bleed line 23 leads from the main feed line 18 and part of the oil delivered by pump 19 is diverted through line 23 and returned to tank 16 either through line 24 or line 25 via a distributor 26. The flow through lines 24 and 25 are respectively controlled by flow regulators 27, 28 which have different flow speed ranges and are respectively under the control of mechanical records 32, 31 of a pre-established speed/time programme. The effect is to move the jack according to the desired programme. To ensure synchronism between the jack 6 and the records 32. 31 the latter are driven, in relation to the jack position, through a servo mechanism 37. 36. 34, 35, 33. In another embodiment (Fig. 2, not shown) the hydraulic pump charges hydraulic accumulators which are used to feed oil to a jack arranged vertically above the dip tank. In one use glass sheets are dipped into a solution of the denier of methyl-ortho-silicic acid in alcohol (150 g. of denier to 300 c.c. of alcohol). Subsequent hydrolysis of the coating gives a transparent coating with good thermal insulation properties.

Abstract: 1,071,285. Thermally-insulated shell mould. HOWE SOUND CO. Aug. 18, 1965 [Sept. 4, 1964], No. 35431/65. Heading B5A. In the production of a refractory shell mould by successively coating a pattern (preferably fusible) with a slurry of a refractory and a binder, hardening the coating and then eliminating the pattern, particulate thermallydecomposable material is evenly embedded in one or more of the coatings subsequent to the first before hardening and subsequently decomposed by heating leaving voids throughout the shell wall, thereby thermally insulating the shell. This prevents defects in castings by reducing the cooling rate thereof. The thermally-decomposable material may be plastics, cork, sawdust, wood chips or corn chips and may be embedded in the layers by being distributed over the surface before hardening or by being dispersed in the slurry used for that coat (however, wood chips may not be used in the latter case). At least one layer excluding the inner layer may define at least part of a multiplicity of voids, the inner layer being free of voids, or alternate adjoining layers, excluding at least the inner two layers, define between them the voids, the remainder being free of voids. The refractory may be zirconium silicate, zirconia, alumina, or silica, and the binder may be hydrolysed ethyl silicate or isopropyl silicate.

Abstract: 460,470. Electromagnetic interrupters. OAK MANUFACTURING CO. Dec. 23, 1935, No. 35568. Convention date, Dec. 24, 1934. [Class 38 (v)] An electromagnetic interrupter which may be used in connection with the high tension supply units of motor car radio sets comprises a flat flexible reed member to which is secured an offset and substantially rigid arm carrying a contact adjacent its free end, this contact being arranged to engage a contact carried by a relatively stationary and substantially yielding member. As shown in Fig. 1, a flexible reed 20 is mounted at its lower end between the limbs of a U-shaped yoke 1 which carries at its upper end a core 3 and winding 5. The reed carries an armature 6 at its free end adjacent the laterally displaced polepiece 4 of the core 3 and carries an interrupter contact 22 and controlled or working contacts 26, 27. The latter are mounted on rigid arms 70, 71 riveted to the reed at their lower ends and bent so as to have offset upper contact-carrying portions. The contacts 28, 29 with which contacts 26, 27 co-operate during the vibration of the reed are carried by flexible springy arms 40. 41 which are, however, stiff enough to ensure that their natural frequency is substantially higher than that of the reed 20. Thus, during the vibration of the reed the contacts 26, 28 and 27, 29 remain in engagement until the mid-position is being passed when a quick-break is obtained. The interrupter contact 21 is carried on an upwardly extending arm formed in a cut-out portion of the reed. A rigid arm 74 riveted to the reed between contact arms 70, 71 bears against the arm carrying the contact 21 at one side so that a rapid break between it and the fixed adjustable contact 23 is obtained. The interrupter contacts are normally in engagement and owing to this and the lateral displacement of polepiece 4 the interrupter is self-starting. The interrupter structure is mounted on an insulating base formed with downwardlyextending plug members 85 and is surrounded by a metal casing 88. The upper end of the interrupter carries a soft rubber cap 100.
