Title: Improvements in and relating to washing and centrifugal drying machines
IPC: D06F17/12
Filed: 1942-03-21
Abstract: 592,840. Centrifugal machines. RASMUSSEN, C. O. March 21, 1942, No. 3779. [Class 23] [Also in Groups VIII and XXIII] In a machine for washing and drying clothes and dishes of the kind including a centrifugal drum 8, Fig. 2, rotatable about a vertical shaft 39 within a cylindrical casing 1, and in which the drum is operatively connected to a vaned wheel 19 driven by the draught from a fan 5 in the upper part of the casing, the vaned wheel is formed as an independent unit also situated in the upper part of the machine, is detachably connected to the drum, and has a peripheral flange 29 which makes a fluid-tight joint with a washing bell during the washing operation. For drying, the washing-bell is removed and the clothes placed in the centrifugal drum which is rotatable on a ball-bearing 44 at the top of the shaft 39. The shaft is rockable about its pointed lower end in a holder 26 removably mounted in a bush 25 rigid with the bottom of the casing. Stabilizing-springs 22 control the gyratory motion of the shaft. The vaned wheel 19 is secured to the drum by pins 70 and a wing-nut 48. Upon energization of a motor in a cover 2, the fan 5 draws air up through an aperture 21 and expels it radially through the vaned wheel, thus causing the wheel and drum to rotate. A modified machine is shown in Fig. 3 with all the parts in the positions they occupy when the machine is not in use. In this embodiment, the centrifugal drum 8 is freely rotatable on a shaft 33 mounted in gimbals 67 supported by a removable fake bottom 64. The gyratory motion of the drum is stabilized by springs 68. The vaned wheel 19 is situated below the fan 5 and is provided with a sealing ring for seating on the drum and bell. The drum is brought to rest by camactuated braking blocks 51 mounted on leaf springs 61 and adapted to bear against a smooth conical or spherical surface 49 on the wheel 19. The brake-actuating handles 60 interlock with clamps 59 to ensure that the drum is stationary before the cover 2 can be removed.

Filed: 1945-02-15
Abstract: <PICT:0590214/III/1> An apparatus for dehydrating lubricating oil comprises a heated jacketed expansion chamber, with an upper discharge opening, and an oil heating device mounted therein provided with means for flashing the heated oil, introduced therein under pressure, into the expansion chamber on to the upper part of the jacketed wall. The moisture is flashed into steam which is discharged and the dehydrated oil falls to the bottom of the expansion chamber, condensation of the steam being avoided by the heated jacket.  The oil heating device preferably comprises a tubular heat exchanger. In one form of such apparatus a tubular heat exchanger 17 is mounted within a jacketed expansion chamber 1 having a steam discharge outlet 11, and is provided with a spring-urged poppet valve 39 mounted in a tubular extension 34 of the upper header of the heat exchanger.  Both the heat exchanger and jacket may be steam heated.  The tubes of the heat exchanger are provided with metal rope-like inserts 43 to facilitate heat conduction to the oil and to cause the latter to flow in thin helical streams.  To prevent the flow of the oil into the interior of the inserts, they may be capped with molten metal such as lead or solder, or alternatively a metal rope having a core of hemp or similar more plastic material may be used.  The flow path for the oil may be enlarged by removal of one or more metal strands of the rope.  A steam jet 15 for discharging a jet of steam just below the discharge outlet 11 may be provided to prevent influx of air; in a modification, a baffle below the opening is used for the same purpose and for preventing loss of entrained oil.

Title: Apparatus for attaching articles to a display card
IPC: B65B15/02
Filed: 1957-02-05
Abstract: 863,980. Attaching articles to display cards. BRADBEER, S. T. May 5, 1958 [Feb. 5, 1957], No. 3872/57. Class 94(1). Apparatus for attaching elongated articles to display cards comprises a support on which a card 1 is laid, and pairs of hooks 3 which project through apertures 2 to receive an elastic band 4. The hooks descend to pull the ends of the band through the apertures and separate to form loops through which the article 6 is thrust. The hooks of each pair then come together again and are disengaged from the band. The machine described cards a number of articles simultaneously. The hooks 3a, 3b, are carried on elongated slides 42, 43 respectively, the sliders operating in a vertically moveable member 35. The member 35 is carried by a frame 31 capable of ' horizontal reciprocating movement. The articles are placed in grooves 11 in the support at the top of the apparatus and are fed forward by a horizontally reciprocated bar 52 bearing groove engaging members 53. In operation, a card is placed on the support to receive the hooks and the bands are placed by hand on the latter. A hand crank 21 is then turned to drive the camshaft 25 causing motion of the members 31, 35, 52. Initially the member 35 descends, pulling the bands through the apertures, and during this descent, extensions of the slides 42, 43 engage cams 44, 45 to cause separation of the hooks. Before bottom dead centre, the members 53 feed the articles into the loops so formed and a final descending movement causes the sliders to clear the cams 44, 45 permitting their return and the closing together of the hooks. The frame 31 first moves in one horizontal direction, and then in the opposite direction to disengage first one pair then the other of each set of hooks from i the respective band. The member 35 may then rise again, cams 44, 45 pivoting upwards to clear the sliders. It is stated that the machine could be fully automatic and electrically or hydraulically operated (not detailed). The Provisional Specification describes a duplex machine in which articles are fed towards the card from two sides instead of one as above.

Title: Improvements in current-responsive thermally-tripped electrical switches
IPC: H01H73/30
Filed: 1951-02-19
Abstract: 690,772. Automatic circuit-breakers. GENERAL MOTORS CORPORATION. Feb. 19, 1951 [March 7, 1950], No. 3923/51. Class 38 (v) A thermally-tripped overload-responsive switch comprises a conducting spring arm 22 bifurcated at its free end to provide a pair of prongs 29, 30, the prong 30 carrying a contact 41, and a bimetallic strip 35 having a portion 37 carrying a contact 42 and a portion 40 which acts as a latch for the prong 29. The switch is closed by pressing in a plunger 50 so that an abutment 54 thereon moves the prong 29 up above the latch portion 40, the engagement of the prong 29 with the latch portion 40 holding the switch closed when the plunger is released. The stressing of the spring arm 22 during this movement brings the contact 41 into engagement with the contact 42. Under overload conditions, the current flowing in the bimetallic strip 35 heats it, causing it to deflect outwardly so that the latch portion 40 is moved aside. The prong 29 is released and both prongs 29 and 30 move downwards opening the contacts 41, 42.

Title: Improvements in or relating to Self-measuring or Automatic Measuring Pumps.
Inventor: MACLEOD ARTHUR WILLIAM
IPC: F04B9/14
Filed: 1917-03-21
Abstract: 112,857. Macleod, A. W. March 21, 1917. Rack-and-pinion actuated pumps; full-stroke devives ; stroke, varying; measuring devices. -A pump for delivering measured quantities of liquid comprises a rod D provided with a number of stops F, G, H, U arranged in grooves in a body E and adapted to engage a projection C on the pump-rod A to limit the movement of the piston. By turning the rod D by means of a handle s so as to bring different grooves into engagement with the projection C, the stroke of the piston may be varied. The body E can be rotated only when the piston is at the bottom of its stroke. Each stop may have a screw t for additional adjustment of the stroke. The pump-rod carries a rack B actuated by gear-wheels, and the shaft c of the pinion f carries two ratchet wheels g, h, one or other of which is always engaged by one of the pawls j, k carried by a sleeve loose on the shaft b and pressed towards the ratchet wheels by a spring piston m. The rod D is capable of slight longitudinal movement so that, when the toe C engages the stop, the rod is raised, and one of two cams r, r<1> thereon moves one of the arms p, g on the sleeve carrying the pawls, and thus disengages one pawl and engages the other with its ratchet wheel. This arrangement prevents reversal of the stroke before its completion. The ratchet wheels may be replaced by frictionally-operated free wheels or by oppositely notched straight racks fixed to the rack B.

Title: Improved polycarbonate process
Filed: 1960-02-05
Abstract: In a process for making a thermoplastic polycarbonate resin by reacting a dihydricphenol with phosgene in the presence of an alkali metal hydroxide, reproductibility of the process (i) is ensured by using an amount of alkali metal hydroxide sufficient to impart a pH of 10.5 to 11.55 (preferably, 10.8-11.3) to the reaction medium during the phosgenation period.  Preferably, the dihydric phenol together with an aqueous solution of an alkali metal hydroxide in an amount equivalent to 5-80% of the stoichiometric quantity required to react with the dihydric phenol and an organic solvent for the intermediate polymer (e.g. methylene chloride) is charged to a reaction vessel and phosgene and additional alkali metal are then added simultaneously in such a manner to maintain a pH of 10.5-11.55. Then phosgene alone is added until the pH has dropped to at least about 10 (preferably about 7) and the intermediate polymer is further polymerized by adding a further quantity of sodium hydroxide and a quarternary ammonium compound (e.g. benzyltrimethylammonium chloride) and stirring. Finally the high molecular weight polymer is neutralized with acid, washed, coagulated (e.g. by stirring with isoprosanol), filtered and dried.  The initial reaction mixture may also contain a chain-terminating agent (e.g. phenol or pphenyl phenol) and sodium hydrosulphite as an anti-oxidant.  Examples describe the preparation of polycarbonates of 2,2- (4,41\hE-dihydroxy diphenyl)-propane.

Title: An improved cold-cathode relay device
IPC: H01J17/04
Filed: 1950-02-21
Abstract: 757,781. Detecting smoke by radiation. ELECTRO-WATT ELECTRICAL & INDUSTRIAL MANAGEMENT CO., Ltd. Feb. 21, 1950 [Feb. 21, 1949], No. 4422/50. Class 40 (3). [Also in Groups XL (a) and XL (c)] A fire and smoke detecting arrangement comprises a cold cathode trigger tube B (see Group XL (a)) having an anode A, a cathode K and a starter anode Z forming with the cathode a control gap across which is connected a small condenser C. The tube construction is such that the control gap has a negative characteristic at very low current values and the tube will operate with a control current of the order of 10<SP>-7</SP> to 10<SP>-12</SP> A. The controlling elements are a photo-electric cell 1 connected in series with an open ionization chamber 4 containing a radioactive preparation 7. A resistance element 8 is connected in parallel with the cell 1 and may be another ionization chamber to compensate for the effect of changes in density on the potential of the starter anode Z as described in Specification 536,594, [Group XXXVI]. The conductivities of the ionization chamber 4, the resistance element 8 and the cell 1 are chosen so as to provide normally a potential on the starter anode Z which is insufficient to trigger the tube B. A beam of light 12 from a source 13 is directed near the cell 1 by a lens 14 and is diffracted by smoke in the air to strike the cell 1 and increase the conductivity thereof. In addition, the smoke interferes with the ionizing action of the radioactive preparation 7 in the chamber 4, as explained in the above-mentioned Specification, and the conductivity of the chamber is reduced. The potential on the starter anode Z is thus raised sufficiently to trigger the tube B and operate a relay R connected in series with the supply source D. Either the photoelectric cell 1 or the ionization chamber 4 may be omitted, and a deionizing chamber 9 may be provided in parallel with the cell 1 or may replace the cell. U.S.A. Specification 2,408,051 also is referred to.

Abstract: 625,470. Actuation of switches. JEFFREY MANUFACTURING CO. Feb. 18, 1947, No. 4642. Convention date, Sept. 12, 1945. [Class 38(v)] In a switch for indicating a particular level of material in a bin or container, a diaphragm 12, backed by a disc 33. is connected to a plate 19 pivoted at 20 to a fixed bracket 18. A disc 21, carrying a normally-open mercury switch 26, is adjustably pivoted at 22 to the plate 19, which also carries at 30 an adjustable counterweight 29. The parts 21 and 29 are pre-adjusted, so that the centre of gravity of the pivoted parts lies to the left of a vertical plane through the horizontal axis 20, so as normally to bias the diaphragm outwards. The switch may be arranged vertically (as shown), or horizontally, with suitable adjustment of the parts 21 and 29. The force required to close switch 26 may be adjusted by moving the centre of gravity and by increasing the angle through which the plate 19 must move to close switch 26.
