Title: Improvements in display apparatus used in connection with the sale of oil cloth, linoleum and the like
IPC: A47F7/17
Filed: 1922-08-19
Abstract: 205,622. Taylor, L. Aug. 19, 1922. Roll holders.-In display apparatus for rolls of linoleum of the kind comprising a rotatable base support mounted on ball bearings and an upper support carried by a wall &c. bracket as described in Specification 123,274, the upper end of the roll is frictionally engaged by a spring controlled cone which acts to rewind the roll after it has been partly drawn out for display purposes, means being also provided for partly disengaging the cone to enable a greater length of the roll to be drawn off without overstraining the spring. The cone a frictionally engaging the upper end of the roll i, is provided with a cylindrical part e carrying a screw bolt or spindle b which is rotatably fitted in a fixed bracket c. Within a casing f secured to the bracket c, a spring d surrounds the cylindrical part e being attached to the cone at one end and at the other end to the bracket c so that when the roll is partly unwound the spring is stressed and rewinds it on release. To enable the cone to be partly disengaged from the roll when greater lengths are to be unwound, the arm of the bracket may be hinged at the angle j.

Abstract: 856,607. Reciprocating generators. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 2, 1959 [July 2, 1958], No. 22721/59. Class 35. An electrical pulse generator comprises a closed cylinder 12 having a fixed permanent magnet 14 which holds magnetically a further magnet 15, the latter being repelled by the approach of a control magnet 13 to pass through coil 17 giving a voltage pulse. To produce a current impulse the magnet 13 is pushed down through a push button 11 extending through cover plate 10 and when the repulsion of magnet 13 overcomes the attraction of magnet 14, the magnet 15 moves downward with a snap-action. In another embodiment two magnets 24, 27 are attached to a cylinder 25 passing through a soft iron body 26, the lower magnet being attached to the body by repulsion from a permanent magnet 28. On operation of the button 20 the repulsion of magnet 22 forces the cylinder down and a voltage pulse is generated in a pair of coils 23 which may be connected in series or may be separate. The control magnet 13 of Fig. 1 may be replaced by a spring connected between the push button 11 and magnet 15.

Car washing apparatus comprises a continuous rail loop 12 supported by beams 10, 11 and from a lower flange 12a of which is suspended by two pairs of rollers 14 a carriage 13, the carriage including a motor 23 which drives a pneumatic rubber traction wheel 25 engaging the outer face of the rail web and supporting a square-section pipe 33, formed of vertical and horizontal legs 33a and 33b, on which are mounted spinner jet units 34. The carriage comprises structural members 15 and 16 which rotatably mount the rollers 14 and stabilizing rollers 17. End-plates are welded to member 15 and a plate 21, vertically hinged at 20 to one of the end plates, mounts the motor 23. The plate 21 is biased towards a position parallel with member 15 by a spring-loaded bolt 29. A housing 26 surrounds motor 23 and traction wheel 25. The outer face of the rail web has stuck to it a foraminous aluminium strip 28. The jet units 34 are mounted on both legs of pipe 33 by means of an L-shaped fitting 36 which has a bore in communication with the interior of pipe 33, and which rotatably mounts in its outer end a pipe 39 connected via a T-piece 42 to two arms 43 terminating in nozzles 44.

Abstract: 1,145,105. Bayer process. REYNOLDS METALS CO. 24 May, 1966, No. 23072/66. Heading C1A. In the Bayer process a slurry of aluminous ore in a quantity of caustic soda between that stoichiometrically equivalent to the silicon and that equivalent to both the silicon and the alumina in the ore is predigested at 150-490 F. for a time sufficient to precipitate dissolved silica as an insoluble desilication product, which remains suspended in the slurry and does not scale the heat exchange and other plant, and thereafter the digestion is completed with additional caustic alkali. As shown in Fig. 2, bauxite is slurried with 12-35% of the caustic liquor (i.e. recycle liquor plus make-up caustic); and this slurry, containing 25-50 wt. per cent solids, is heated by indirect heat exchange, with live steam and/or flash steam from flash cooling the digested slurry, to the predigestion temperature. After predigestion for ¢ to 12 hrs. at a temperature close to its atmospheric boiling point, the slurry and the rest of the caustic digestion liquor are separately heated to the digestion temperature before being combined and passed to the digester. After digestion at 290-480 F. the digested slurry is flash cooled in the stages 13, 14 and 15 and passed to the usual Bayer process stages 20 to 28. According to Fig. 1 (not shown), the predigested slurry may be combined with the major part of the caustic before heating to the digestion temperature.

Abstract: 404,393. Reversal development of photographic films. UNIVERSAL PICTURES CORPORATION, Universal City, California, U.S.A. Aug. 18, 1932, No. 23205. Convention date, Oct. 16, 1931. [Class 98 (ii).] Relates to a device for producing positive photographic films, of the kind in which the film is drawn from a magazine through solutions in a series of elongated troughs and is then fed to another magazine, the operation being uninterrupted and continuous. According to the invention, some of the troughs have more than one compartment, and means are provided for directing the film from the compartment of one trough to the compartment of another trough before the film is returned by pulleys to the second compartment of the first trough. In the form shown in sectional elevation in Fig. 1 and diagrammatically in Fig. 2, three troughs are arranged one above the other. The exposed film from a magazine 17 enters the compartment 6 containing a developing solution, being guided therein by pulleys 23-26 and a pulley system 27 comprising three pulleys 28-30. Thence the film is directed by pulleys through compartments 8, 13, 12 and 16 containing stop, washing, reversing and washing solutions respectively. The film is then led under fogging lamps 18 and is then directed by pulleys through compartments 5, 11 and 15 containing clearing, developing and washing solutions. On leaving the compartment 15 the film passes between air jets 19, 20 which remove all surplus moisture, and is then passed in a circuitous path through a drying chamber 21, through which it is drawn by a take-up reel or magazine 22. In a modification, each trough is provided with several co-axial pulleys, so that a number of films can be treated simultaneously. Specification 360,082 is referred to.
