Title: Improvements in pumps
IPC: F04C2/107
Filed: 1963-12-23
Abstract: 1,047,769. Rotary pumps. SOCIETE GENERALE DE MECANIQUE ET DE METALLURGIE S.A. Dec. 23, 1963 [Dec. 28, 1962], No. 50718/63. Heading F1F. A rotary pump comprises a plurality of circular plates 6 (Figs. 1 to 4, not shown) lodged within a flexible tubular sheath 7, each plate being provided with a rectangular aperture 8 at its centre in sliding engagement with a rotatable helical driving-shaft 10. The body of the pump includes inlet and outlet chambers 2, 3 at opposite ends of a cylinder 1 whose inner surface has a profile in crosssection which comprises two semi-circular portions with two straight portions of length c therebetween, said length being equal to the eccentricity of the cross-section of the shaft 10. The diameter of each of said semi-circular portions is substantially equal to the outer diameter of the sheath 7 so as to effect sealing between the cylinder 1 and the sheath. The plates 6 are also provided with elongated apertures 9 which slidably engage with fixed rods 15 extending from one end of the pumpbody to the other whereby rotation of the shaft 10 causes the plates 6 and the sheath 7 to oscillate transversely of the cylinder 1 without rotation so as to displace fluid from the chamber 2 to the chamber 3. The helical pitch of the shaft 10 is rendered less than or equal to the length of the cylinder I to prevent direct communication between the chambers 2, 3. When the fluid to be pumped is compressible, the helical pitch of the shaft 10 may be non- uniform so as to effect compression of the fluid. Lubricant for the plates 6 and bearings 13 supporting the shaft 10 is supplied through a conduit 39. Alternatively, lubricating oil is circulated through a reservoir 42 (Fig. 5, not shown) at one end of the pump-body, and a plurality of apertures 41 in the plates 6. The shaft 10 may have a three-lobed profile in cross-section (Fig. 7, not shown); and the apertures 8 may be provided with a wearresistant lining 20 on opposite sides thereof. The plates 6 may be made of cotton-reinforced phenolic-resin material which is loaded with graphite; and the sheath 7 may be made of an oil-resistant elastomeric material with its radially outermost surface coated with a thin layer of a material e.g. P.T.F.E., chloro-sulphonated polyethylene, polytrifluoromonochloroethylene or a copolymer of fluorovinylidene and hexafluoropropylene, which is inert with respect to the fluid being pumped. The cylinder 1 may be provided with a semi-rigid lining made of e.g. hard rubber, to minimize leakage of fluid between the sheath 7 and the cylinder 1.

Title: Improvements in viscose spinning process
Inventor: BROWER PAUL VERNON
IPC: D01F2/06
Filed: 1963-12-23
Abstract: 1,069,499. Spinning viscose. BEAUNIT CORPORATION. Dec. 23, 1963, No. 50727/63. Heading B5B. Regenerated cellulose filaments, films &c. are produced by extruding a viscose to which has been added, in a proportion insufficient to cause coagulation of the viscose prior to extrusion, a soluble viscose-coagulating salt of a strong base and a weak acid into an inorganic acid spin bath containing the sodium and zinc salts of the acid in the presence of a sugar, a polyalkylene glycol having an average molecular weight of at least 400 (or an ether or ester derivative of such a glycol), and a water-soluble hydroxy fatty acid. The viscosecoagulating salt is preferably a soluble sulphide, but may be sodium acetate or sodium phosphate. Metal salts, especially alkali metal salts are preferred. The term " soluble " as applied to these salts refers to their being soluble in viscose, irrespective of their solubility in water. The glycol (or the derivative thereof) the hydroxy fatty acid and the sugar, may be added to the viscose, the spin bath or both. The sugar is preferably a hexose such as glucose. The hydroxy fatty acid preferably contains from 2 to about 6 carbon atoms in the molecule with the hydroxy group preferably in the alpha position. The salt point of the viscose is preferably about 7.5 to about 9À0. The concentration of zinc salt in the spin bath is preferably about 4 to 8% or more. The polyalkylene glycol may be polyethylene glycol, polypropylene glycol or mixed polyethylenepolypropylene glycol, said glycols having an average molecular weight of from 400 to about 9000. The viscose-coagulating salt may be sodium sulphide and the proportion of sodium sulphide in the viscose may be at least 2%.

Title: Improvements relating to the production of highly transparent flat film
IPC: B29C48/08
Filed: 1965-11-30
Abstract: 1,122,416. Melt extruding flat film. J. P. BEMBERG A.G. 30 Nov., 1965 [1 Dec., 1964], No. 50803/65. Heading B5B. In producing highly transparent flat film by melt extruding a synthetic organic polymeric material through a slot die on to an internally cooled cooling roll and contacting the film during its passage over the draw roll with a liquid coolant, the extrusion die and the draw roll are relatively so disposed that the length of the free path of travel of the film through the air from the extrusion die to the line at which the film first contacts the draw roll is short and the peripheral outer surface of the draw roll is continuously coated with a liquid coolant containing an anti-blocking agent either by arranging for the draw roll to be immersed to a shallow depth in a bath of the coolant in such a manner that both a portion of the peripheral surface of the draw roll covered by the film and a portion of the peripheral surface of the draw roll emerging from the bath and not covered by the film is immersed in the bath of coolant. Alternatively, the draw roll may be entirely surrounded by air and the liquid coolant sprayed on to a portion of the peripheral surface of the draw roll approaching the line of first contact of the film with the draw roll. In this case the film is caused to pass to a second draw roll over and in contact with which it travels in such a manner that the surface of the film which was exposed to the air during the passage of the film over the first draw roll is in contact with the peripheral surface of the second draw roll and liquid coolant is sprayed on to the surface of the second draw roll approaching the line of first contact of the film with the second draw roll. The liquid coolant may be water, the surface tension of which has been reduced by the addition of a wetting agent, an organic liquid which is a non-solvent for the film material (such as isopropanol) or an aqueous dispersion of a synthetic organic polymeric material. The coolant may contain an anti-static agent.

Title: Lighting Systems for Road Vehicles
Inventor: JONES KENNETH JAMES
IPC: B60Q1/14
Filed: 1966-11-14
Abstract: 1,190,010. Vehicle lighting system. JOSEPH LUCAS (INDUSTRIES) Ltd. Oct. 26, 1967 [Nov. 14, 1966], No. 50876/66. Heading G1A. A vehicle headlamp system in which a shutter is moved in front of the headlamp beam in response to the detection of light from an oncoming vehicle, is adapted for use both in countries having a left hand rule of the road and countries having a right hand rule of the road. Light from an oncoming vehicle is focussed by lens 19 into an aperture 22 and by lens 24 on to a photo-cell 25. The cell output is amplified and applied to the winding of a "milliammeter" in which the pointer is replaced by a pulley wheel. This is caused to pull a cable and move shutters 18, 18a across the aperture 15 in such a direction that one of the shutters cuts off part of the headlamp beam from filament 12. The direction is selected in dependence upon the rule of the road of the country in which the vehicle is being driven and is chosen by switching a reversing switch, connected between the photo-cell amplifier and the "milliammeter", into the appropriate one of two positions. As well as movement of shutters 18, 18a, shutters 27, 27a are moved in the same direction across the photocell field of view. Slight oscillation of both sets of shutters occurs before a final position is attained in which the light issuing from the headlamp is so directed as to prevent dazzling of the oncoming vehicle's driver. Eddy current damping of the movement of the shutters and damping of the "milliammeter" are also provided. The leading edge of a shutter 18, 18a is in advance of a shutter 27, 27a to ensure that the oncoming driver's eyes are always in shadow. To prevent shutter movement due to reflection of the headlamp beam from an oncoming vehicle, red and infra-red wavelengths may be filtered out of the spectrum of the headlamp beam and the photocell be principally sensitive to such wavelengths.
