Title: Page turning device
IPC: B42D9/04
Filed: 1976-08-27
Abstract: 1531834 Page turner F J WINTERTON 27 Aug 1976 [5 Sept 1975] 35833/76 Heading G5X A page turning device has a plunger 13 which reciprocates vertically relative to a publication mounted on a support 11 on the application of fluid pressure through a mouthpiece attached to a tube 19 and is arranged to raise a page 21 of the publication which is then turned by a second horizontal fluid operated plunger 29 on the application of fluid pressure through a mouthpiece attached to a tube 31. The plunger initially rests on the right hand edge of page 21 and, when suction is applied through the mouthpiece and tube 19, lifts the page past a retainer 23 which allows the page to rise but prevents it falling back. By blowing through the same or another mouthpiece and tube 31 plunger 29 which is normally spring biased into the retracted position is extended horizontally to turn the page. A retainer 33 holds the turned page down. The plunger mechanisms may be adjustable relative to the support 11.

Title: Improvements in the preparation of rubber-resin products from latex
IPC: C08L21/00
Filed: 1955-12-14
Abstract: An acid stabilized latex of natural or synthetic rubber is acidified, mixed with formaldehyde and a mixture of urea and melamine, and the resin components are then fully condensed in the latex; the rubber-resin product is separated and, if desired, vulcanized.  The vulcanized product may be suitable for the manufacture of motor-car tyres.  In examples the latices used are of natural rubber or of butadienestyrene copolymers, and they are stabilized by the addition of 10 per cent by volume of 20 per cent "Emulphor O" (Registered Trade Mark) solution.  The weight ratio of rubber to resin preferred is 70-75 to 30-25 and of urea to melamine 75 to 25.  In order to prevent premature condensation or coagulation, three separate solutions are prepared, a solution of melamine in formaldehyde of pH 10 and temperature 80-90 DEG  C., a solution of urea in formaldehyde of pH 7-8 and temperature 30-50 DEG  C., and an acid-stabilized latex of pH 3-7 and temperature not greater than 50 DEG  C.; these three solutions are then mixed and maintained at pH 3-4 and 80-85 DEG  C. for 2 hours. After being cooled, neutralized, washed and dried, the rubber-resin product may be vulcanized by such mixtures as zinc oxide, stearic acid, N-cyclo hexyl-2 benzothiazole-sulphenamide, and sulphur with Agerite Alba, phenyl-b -naphthylamine, or styphen V, for times ranging from 1/4 to 1 hour and at temperatures from 127 DEG  to 142 DEG  C.ALSO:An acid-stabilized latex of natural or synthetic rubber is acidified, mixed with formaldehyde and a mixture of urea and melamine, and the resin components are then fully condensed in the latex: the rubber-resin product is separated, and if desired, vulcanized.

Abstract: 828,032. Boring-machine details. BRINEY MANUFACTURING CO. Nov. 19, 1957, No. 35984/57. Class 83 (3). An axially and radially-adjustable coupling for connecting a boring-bar to a boring-machine comprises: a flanged housing 10 connectable to the machine spindle at 12 and having a bore 16; a sleeve 28 rotatable in bore 16 and having its external surface 32 slightly eccentric to its bore 30; and bearings 44, 45 fitting between the housing, the sleeve and the boring-bar. The ball-bearings are pre-stressed. In use, the boring-bar is connected to the coupling by a plug 54, which is screwed to the boring-bar and is keyed at 62 to the housing, so that the bar can be moved axially but not angularly, relatively to the housing. The sleeve, having a conicallocation surface 34, is urged towards an abutment 18 of the housing by springs 60, in recesses 58 of the plug 54. Axial adjustment is obtained by rotating a screwed collar 50 on a threaded portion 48 of the boring-bar, and radial adjustment by rotating the sleeve. The axial and radial adjustments are made independently, and locking is unnecessary due to the action of springs 60.

Abstract: 787,443. Harvesting beet. STOLL, W. Dec. 20, 1955 [Dec. 24, 1954], No. 36445/55. Class 6(3). A beet-harvesting machine is provided with shares arranged in V-fashion, the apex of the V extending rearwardly and downwardly. In one form shown, the shares 19, 20 are secured to stems 9, 10 which are mounted by U-bolts 12 on a cross-bar 11 so that the shares are adjustable vertically and transversely. The shares have rearwardly-extending parallel portions 23 at their rear ends which define a throat to accommodate the tails of the beets. Rods 24 extend rearwardly to a cleaning drum 25. On one side an inclined rotary spinner 26 replaces the rods 24. In a modification, the drum 25 extends laterally of the shares and the rods 24 are bent around in arcuate formation to deflect the beets through 90 degrees. The inner edges of the shares are rounded.

Title: Improvements in or relating to electrothermic indicating apparatus
IPC: G01K1/02
Filed: 1957-11-22
Abstract: 828,975. Electrothermic indicating apparatus. KALLE, K. T. Nov. 22, 1957 [Dec. 5, 1956], No. 36510/57. Class 40 (1). In a system in which one of a pair of thermally self-interrupting contacts 12, 11 is moved towards and away from the other by a variable to be measured such as temperature, pressure, position, so that the average current through the contacts represents the value of the variable, the contacts are kept clean by continuously vibrating one of them transversely electromagnetically. As shown, a Bourdon tube 26 actuated by a temperature-sensitive probe 24 determines the position of contact 12. That of contact 11 is determined by the length of a wire 19 heated by a coil 13 in series with the interrupter contacts and with a thermally operated indicator 22. The transverse vibration is imparted to the contact 12 by a magnetic plate 29 which as shown is mounted near to a groove in the magnetic circuit of the supply transformer. Alternatively, plate 29 may be arranged near to a gap in a magnetic circuit provided by magnetic extensions from the transformer core, Fig. 4 (not shown). To reduce sparking, the self-interrupting circuit is shunted by a resistor 10. As a further alternative, the interrupter contacts may be in the primary circuit of the transformer and the heater and indicator in the secondary circuit.

Filed: 1963-09-18
Abstract: 1,037,438. Spinnerets. E. I. DU PONT DE NEMOURS & CO. Sept. 18, 1963, No. 36810/63. Heading B5B. A spinneret plate for spinning filaments having a multi-lobal cross-section comprises a solid plate having at least one patterned orifice therethrough, having at least two straight arms extending outwardly and in an angular direction from a central portion, with the smallest angle between adjacent arms being less than 180 degrees, each arm intersecting the central. portion thereby providing communication from arm to arm, at least two of the arms being traversed by slots which intersect the arms at a position remote from the central portion and spaced from the extremities of the arms, each of the slot-traversed arms having a perimeterto-area ratio P/Q of at least 0À5. Where the units of measurement are thousandth of an inch the slots may intersect the arms (length L 0 ) at a distance D between 0À2 L 0  and 0À8 L 0  from the intersection of the arms and the central portion. The slots may be comprised of two fins of length L F  which is at least 1À5 W 0  (width of arms). The orifice may have four arms equispaced about a central point, two of the arms opposite each other being traversed by slots. The cross-section of filaments melt-spun through the orifices may be controlled by controlling the quenching conditions. Also the crosssection may be controlled by spinning through an adjustable orifice having movable slots. Since the material flowing through the orifices of the invention is forced to take a configuration having a high surface area/volume ratio, solidification of the material passing through the arms of the orifice is rapid, and the multilobal form of the filaments is achieved without use of extreme quench conditions.

The stem is normally pressed outwards by a spring 54 fitted between a washer 56 above the gasket 57 and a flange 52 on the stem, so that a port 50 establishes communication between the measuring chamber and the interior of the container. On depressing the stem, an outlet port 44 moves into the measuring chamber and the port 50 moves below a gasket 66. The capacity of the chamber may be varied by fitting plugs of differing inside diameter or by using estra washers in the chamber.
