Title: Improvements in or relating to the manufacture of parchmentised or vulcanised fibre
IPC: D21H11/20
Filed: 1925-08-17
Abstract: 260,374. Arnot, R. Aug. 17, 1925. Boards; parchment paper; fireproof paper; paper, treating with special materials.-In the manufacture of parchmentized or vulcanized fibre by hydrolyzing-cellulose fibre such as paper with zinc chloride or other suitable salt or acid, the last traces of reagent are neutralized, and the corrosive tendency of the product overcome by the use of a medium or media which, while not injuriously aftecting the treated cellulose material will form with the remaining hydrolyzing agent an insoluble product, of an addition product, and thus render lengthy washing after parchmentizing unnecessary. These media may be added to the hydrolyzing liquid or they may be applied before or after treatment therewith. Where zinc chloride is the hydrolyzing agent used. the following media may be employed-a solution of an alkali, or of a salt of silicic or phosphoric acid or of sulphuric acid, an oleate, resinate, salt of casein or pyridine, an albuminate, an amine or other organic base. a solution of a salt which will give an insoluble chloride such as lead acetate, or silver nitrate, an oil such as Tungoil used alone or dissolved in acetone or like solvent, such material, as also soft soap, rendering the product flexible and waterproof. The use of an alkaline silicate such as sodium silicate yields a fireproof product. When zinc chloride is used, alkaline soap and some oils produce on the surface a coating of a very sticky zinc soap and may be used when it is desired to combine several sheets to form a solid plate or block under heat and pressure. Chinese wood oil produces a rubber like surface which needs to be treated with an oxidizing agent such as dilute chromic acid or a solution of iron chloride in acetone. Rubber latex or a drying oil such as Tung oil may be applied to the cellulose material before hydrolysis. Dyes may be added to the neutralizing agent or the product may be passed subsequently through a separate dye solution.

Abstract: 693,338. Supply meters. SANGAMO WESTON, Ltd. Aug. 31, 1951 [Nov. 14, 1950], No. 20631/51. Class 37. In a polyphase watt-hour meter a differentias form of torque balance adjustment device is provided. In Figs. 2, 4 and 5, torque adjustment is effected by operating a single adjustment screw 32 whereby a non-magnetic slider 20 carrying upper and lower pairs of oppositelytapered flux shunting shoes 27 moves across the driving electromagnets 2 with the flux shunting shoes 27 in bridging relation to leakage paths or gaps 18 in each electromagnet 2. The shoes 27 are so disposed that going from one adjustment extremity, Fig. 4, to the other, Fig. 5, the upper shoes are withdrawn from full to zero bridging of their gaps 18 and the lower shoes advanced from zero to full bridging of their gaps 18 whilst maintaining constant the total driving torque acting on rotors or discs (not shown) resident in slots or gaps 11. The slider 20 slides on a frame 21 clamped to the bases of the electro-magnets 2 and formed with phosphor-bronze side strips 24 aligned with the gaps 18 and thus constituting tracks for the shoes 27 which are pivotally suspended from resilient side strips 26 of the slider 20.

Abstract: 1513481 Blood circulation stimulator M KAWAGUCHI 19 May 1976 [14 June 1975] 20763/76 Heading A5R A blood circulation stimulator comprises an inflatable air bag 11 which is shaped to fit a portion of or all the body and is supplied with compressed air from a compressor 16 in a pipe 18 having an exhaust port 17 to atmosphere controlled by a valve 13 comprising a solenoid 20 acting on a closure plate 21, and an electric circuit, Fig. 1, which energises the solenoid to close the valve, detects the forced opening of the valve when air pressure in pipe 18 overcomes the magnetic force of the solenoid valve, deenergises the solenoid and then reenergises the solenoid after a predetermined time interval to reclose the valve. In operation the air is supplied by compressor 16 after start switch 24 is closed and inflates air bag 11, valve 13 being closed; at a pressure dependent on the current in the solenoid as determined by variable resistance 26 the closure plate 21 is forced open breaking contact 23 and by relay R1 the solenoid is deenergised; the decrease in pressure in air supply pipe 19 then causes an exhaust valve 14 to open to atmosphere and rapidly deflate the air bag; after a predetermined time delay relay R2, previously energised by relay R1, closes "make" contact 27 to reenergise the solenoid, close valve 13 and allow the cycle to start again. In an alternative embodiment, Fig. 3 (not shown), a timer (31) is used to determine the length of the cycle.

Abstract: 221,505. Maschinenfabrik Augsburg- N³rnberg Akt.-Ges. Sept. 6, 1923, [Convention date]. Photo-mechanical printing-surfaces. - Planographic printing plates are prepared by first producing a printed text or black and white pen inscriptions or drawings on transparent or semitransparent material such as paper, producing from this positive a negative on transparent or translucent lightsensitized material preferably sepia paper, and printing the negative on to the sensitive plate. Screen negatives of half tone pictures may be stripped from their support and transferred on to the paper negative of the type matter and copied therewith on to the plate, the stripping being preferably effected by means of a temporary support consisting of a thin sheet of flexible transluscent material, such as oiled or tracing paper or celluloid film, to which the screen negative adheres less strongly than to the paper negative. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the transfer of grained half-tone picture negatives on to the paper negative, the graining being preferably effected by using ammonia, dilute caustic alkali solution, and a bath of water and calcium chloride, and also the use of the process for transferring to the printing plate several pictures without letterpress which have been photographed on different plates. This subject-matter does not appear in the Specification as accepted.

Filed: 1936-07-28
Abstract: 464,556. Projectile fuzes. JUNGHANS, H. July 28, 1936, No. 20879. [Class 9 (i)] Relates to directaction percussion fuzes of the kind in which centrifugal safety jaws are provided for the striker and centrifugally operated clockwork mechanism delays the arming of the fuze. According to the invention, a centrifugally operated wheel mechanism controls a rotatable slotted annular casing co-operating with abutments on the centrifugal jaws so as to free these jaws after a given delay. In the form shown, a collar d, Fig. 1, on the striker c is locked by centrifugal jaws e<1> ... e<4>, Fig. 4, which are interlocked in known manner to swing out one after another. The jaw, which is to be the first to swing out, is provided with an abutment pin l, which bears against the inner wall of an annular casing k in one with a pinion i adapted to be rotated by a centrifugal toothed sector g, h, Fig. 3, when this is released by the set back of a spring catch n, n<1> by inertia when the projectile is discharged. The rotation of the casing is delayed by a centrifugal oscillation pawl o co-operating with teeth k<1> around the casing. After a given time, a slot m in the casing comes opposite the pin l and allows this to escape, whereupon the centrifugal jaws swing out and unlock the striker.
