Title: Improvements in aerial ropeway transporters and the like
IPC: E01B25/18
Filed: 1919-08-28
Abstract: 154,972. Hoyle, J. K. Aug. 28, 1919. Rope railways.-Terminal or intermediate angle frames have a rope sheave supported centrally at the apex of an A-shaped or triangular frame with ground anchorage. The frame may be constructed as a flat panel, Fig. 1, with bracing-members and connected by links o to a post u attached by links p and stirrup-bar s to a grillage r. The links p and bar s may be replaced by a rope block, in which case the panel is arranged to slide so as to adjust the tension of the ropeway. The sheave f is driven by a pinion n and is mounted on an eccentric bush g, Fig. 4a. The post E may be connected to the grillage by a tension bar D, Fig. 6, and to the frame by blocks and falls, or by a tension bar C; in the latter case, the bar C may carry a pinion H driven by a shaft J and wheel K. In a reversible ropeway, Fig. 9, the tension bars C are replaced by parallel bars O, and the sheave has rim teeth engaged by pinions N.

Abstract: 627,461. Wheel arrangements. BAIRD, O., and LEES, D. M. Aug. 7, 1947, No. 21633. [Class 108(ii)] A trolley or the like is provided with supporting wheels each having a periphery notched at intervals to straddle a rope and wherein each wheel is provided with a device for pushing the rope in front of the notched wheel until a notch is positioned to straddle the rope. In the arrangement shown, a trolley frame is supported by a pair of wheels b. The tyre d of each wheel b is provided with notches e, each notch being divergent at both sides of the wheel to enable the latter to pass over a rope, such as an aircraft arrester wire f, at various angles to the rope. Pairs of levers h are pivotally mounted on the frame a at the front and rear of wheel b and the front and rear pairs are connected together at their lower ends by link bars g having shoulders g<SP>1</SP> by which the rope is encountered before entering a notch in the wheel b. The link bars are connected together to the front and rear of the wheel b by bars g<SP>2</SP>. The outer levers h of each pair normally bear against plungers j slidable in a tube k between limits determined by screw stops m projecting through the tube k into grooves on the plungers. The plungers are loaded by a single coil-spring l. Inward movement of the plungers is prevented by a bell-crank, one arm n<SP>1</SP> of which normally projects into a gap in the tube k whilst the other arm n<SP>2</SP>, Fig. 2, is loaded by a leaf-spring o and bears on a sliding pin p which rests on a camwheel q rigid with the wheel b. The cam-wheel is so disposed relative to the notches on the wheel b that the pin p is raised to rock the bellcrank and withdraw the arm n<SP>1</SP> to free the plungers whenever a notch e becomes positioned to straddle the rope. The link bar and levers h may be provided on only one side of each wheel b, and the link bar may be in sections, as shown, or comprise a single bar. Also the link bar and levers may be operative in one direction only of travel of the trolley and the notches e may be inclined transversely of the tyre d in one direction only. According to the Provisional Specification the levers are connected by a second link bar in which a lug on a spring-urged plunger engages in a notch thereon to lock the levers when the lower link bar encounters a rope. The plunger is mounted in a guide on the trolley frame and is actuated by a cam-wheel rigid with the trolley-wheel. The levers are connected above their pivots by a link rod having a collar held thereon between two helical compression springs which serve to centre the linkage, comprised by the link bars and levers, so that it may be locked by the plunger after the wheel has passed over the rope.

Title: Improvements in or relating to the manufacture of sliding clasp fasteners
IPC: B21D53/50
Filed: 1947-08-07
Abstract: 630,177. Sliding-clasp fasteners. SILVERMAN, D. Aug. 7, 1947, No. 21641. Convention date, Sept 23, 1944. [Class 44] In a process for manufacturing sliding clasp fasteners, a metal strip of uniform crosssection is advanced in steps towards a tape and passes beneath reciprocating tools adapted to form the projections and recesses on opposite sides of the strip, and a cutting tool to sever fastener elements from the end of the strip, leaving jaws for clamping engagement with the tape. The operations are performed in the following order (a) indenting the projections and recesses 368, Fig. 66, (b) advancing the strip 12 into contact with the tape 172 and clamping the jaws thereon, Figs. 66, 67, and (c) cutting off the portion of the strip secured to the tape to form a completed fastener element, Fig. 68. The shape of the severing cut is such as to leave extra metal in two projections 554 near the roots of the jaws to be swaged into the metal of the element by lateral pressure as shown in Fig. 69. The machine for making the fasteners comprises a base in the form of an oil container through which passes a shaft carrying two eccentrics coupled by connecting rods to the ends of a crosshead secured to a reciprocating ram. A third eccentric on the shaft is connected to the tape feeding means and a cam on the end of the shaft operates the wire feeding mechanism through a lever carrying a ratchet.' A punch block 314, Fig. 64, carried on the ram 272 holds a punch 324 co-operating, with a die 366 to form the projections and recesses, and a cutter 322 co-operating with a shearing block 456. The tools 324, 322 are retained in the block 314 by a clamp plate 326 and the die part is clamped by a block 408 so that all parts can readily be removed for repair. The tools 322, 324 are vertically adjustable by screws 336, 338. A spring actuated lifting plunger 468 is disposed in the die block to lift the wire after the end has been severed so that the wire may be advanced for the next cycle of operations. Transversely sliding jaws 540, Figs. 31, 32 spring loaded apart and actuated by inclined cam surfaces on the ram are adapted to clamp the jaws of an element 546 together on the tape and carry upward extensions 560 to swage the corners 554 of the elements to form flat sides on the preceding element 548. The strip is fed horizontally through the machine by rollers engaging the strip above and below and a ratchet feed for the rollers synchronised with the reciprocation of the ram. The ratchet feed may be rendered inoperative at intervals to produce spaces along the fastener tapes where they are cut to form separate fasteners.

Title: Method of and means for the rapid approximate quantitative estimation of chloride concentration in liquids
IPC: G01N31/22
Filed: 1950-09-05
Abstract: An indicator for the quantitative estimation of chloride concentration in aqueous liquids, e.g. urine, comprises a water-absorbent cellulosic material, e.g., paper or string, impregnated with such an amount of silver chromate that it is bleached within a period of between 5 and 6 seconds when immersed in a 0.3 per cent W/V solution of sodium chloride.  In using the indicator, the time taken to bleach it is measured and compared with a time calibration of the indicator relative to sodium chloride solutions of known different concentrations.  The indicator is made by impregnating the cellulosic material with an ammoniacal solution of silver chromate, the silver chromate then being precipitated by treatment with a dilute acid free of chloride.
