Title: Method and means of transportation by aerial ropeways
IPC: B66C21/00
Filed: 1920-11-18
Abstract: 174,256. Gorrie, J. A. Nov. 18, 1920. Overhead travellers and transporters.-A trolly 3 for an aerial ropeway 1, 2 is provided with means for hoisting the load through a multiple-block svstem, locking and supporting the fall-block 5 on the trolly whilst transporting, the supporting jaws being opened by direct contact with the fall block and closed automatically, and means for releasing the load to permit of lowering whilst the trolly is held at any predetermined point on the ropeway. As shown in Fig. 1, a bracket 6 is suspended from the trolly and carries pulleys 12, 13 forming a multipleblock system with the pullevs 14, 15 of the fallblock. The load is hoisted bv the cable 4, anchored at 4<a>, the fall-block 5 passes up between locking-jaws 19, 20, Fig. 3, on a frame 16 suspended from the bracket 6, and the jaws are then closed beneath the block by springs so that the weight of the load is supported from the trolly. The T-shaped arrangement of the pulleys ensures that the fall-block hangs vertically and in alignment with the supporting-jaws, but the frame 16 may have hinged guides for the block. When the toad is thus supported, the trolly is hauled towards the left by the cable 4 to the terminal or unloading point shown in Fig. 1, where it is held by pawls. In this position the locking-jaws 19 20 engage a collapsable wedge 26 on a frame 29 which is held vertical by an arm 30 engaging an arm 31 on the trolly. When the weight of the load is taken by the hoisting-cable, the wedge is expanded by a spring so as to release the jaws from beneath the fall-block. After lowering, a cap is placed on the fall-block to prevent its entering the jaws, and a light hauling-down rope is attached to the shackle of the block. The block is then raised, and the trolly is run out for the next load by means of the back rope 7. The bracket 6 may be fixed on the trolly, or the frame 16 may be pivoted directly to the carrier. In a modification, Fig. 5, the hoisting, locking, and supporting system comprises a fall-block 5 suspended from a multiple pulley-block 33, in which one member serves merely as a guide pulley, the end of the cable 4 being anchored horizontally. Pivoted on the block 33 are vertical jaws 36, 37 for supporting the fallblock in the raised position. The provision of a guide-pulley in the upper block ensures that the fall-block and the jaws are always in line at any inclination of the suspending-bracket 32. The jaws are held towards the closed position by a spring acting on toggle-levers 40, 41, and are released automatically by the cord 42. This cord is pulled by a spring on the trolly which is extended by a stop at the terminal station engaging a lever on the trolly.

Title: Dynamic binary counter circuit
IPC: H03K3/037
Filed: 1974-07-24
Abstract: 1434468 Transistor pulse circuits NIPPON ELECTRIC CO Ltd 24 July 1974 [24 July 1973] 32759/74 Heading H3T A divide-by-two circuit comprises : an inverter 3 with switches 5, 6 connected in series between its input and its outputs, the switches being controlled by an input signal at 14 such that when one is closed the other is open; a first storage capacitor 7 connected to the input of the inverter; and a second storage capacitor 8 connected to the junction points of the two switches. Assume that during the period t 0  to t 1  the output 16 is at a high level (V volts), that output 15 is at a low level (O volts), that switch 6 is closed, and that switch 5 is open. In this state capacitor 8 is charged to V volts. During the period t 1  to t 2  the input signal changes its state opening switch 6 and closing switch 5 so that the charge on capacitor 8 is applied to capacitor 7 making output 15 V volts, and consequently output 16 O volts. During the period t 2  to t 3  switch 5 is reopened and switch 6 reclosed, so that capacitor 8 discharges to the O volt level present on line 16. The levels on lines 15, 16 do not change during this period. During period t 3  to t 4  the states of the switches are again reversed and capacitor 7 discharges through switch 5 to O volts making output 15 O volts and output 16 V volts again. The cycle then repeats. In practical embodiments, the inverter comprises two series connected field effect transistors of opposite conductivity type, and the switches each comprise a further FET, Fig. 5 (not shown), or a pair of opposite conductivity FET's, Fig. 4 (not shown). The capacitors are constituted by the capacitances inherent in the circuit.

Title: Production of a hard metal coating of carbides on a ferrous mass
Inventor: NUSSBAUM LEON
IPC: C23C28/04
Filed: 1955-11-16
Abstract: A coating of at least one carbide of one or more of Ti, Zr, V, Cb, Ta, Mo and Cr is produced on a ferrous metal mass by applying successive layers of "asymmetric particles" of one or more of the said carbides with or without binder metal(s), and each time a layer is applied heating under non-oxidising conditions both the layer and the underlying surface to which the layer is applied, sufficiently to effect welding of the layer to the underlying surface but insufficient, at least in the case of the last layer(s), to alter materially the asymmetric nature of the carbide particles. "Asymmetric particles" are irregularly shaped incomplete crystals such as obtained by ball-milling.  The layers may be applied as pre-formed laminae, or as powder; heating may be by a gas welding torch or a shrouded arc using carton or tungsten electrodes.  The coating, while still plastic, may be shaped by pressure between metal or carbon formers.  In an Example, 85 per cent re-crystallized carbides (87 1/2 parts Ti C, 11 parts Cb C, 1 1/2 parts Ta C) and 15 per cent Ni-Cr binder alloy of particle size 3m  and less, the carbides being asymmetric, was mixed with 1 per cent of organic binder (20 per cent camphor in acetone) and mortared.  It was then compressed at about 1/2 ton p.s.i. while vibrated in a mould, then presintered at 1200 DEG C.  It was then cast to size, placed on a base of 0.5 per cent carbon steel which was partially immersed in water, and an arc struck with a tungsten electrode shrouded in nitrogen to weld the layer to the base.  This was repeated with two other similar compacted layers and finally with two containing no binder metal.  The hardness of successive layers increased.  In a second Example the powder of the first Example was projected through a nitrogen-shrouded arc struck between a tungsten electrode and the upper face of a 0.5 per cent carbon steel base cooled as before. Successive layers were added each about 1/16 in. thick, the last two being free from binder metal powder. Shaping of each of the above produced layers whilst plastic by means of a steel former using 20 tons p.s.i. maintained the hardness but gave increased shock resistance.

Abstract: 191,576. Ludford, W. C. G. Dec. 8, 1921. Direct air - pressure apparatus, non-automatic. -In an air-pressure liquidspraying apparatus of the kind having a single inlet for both air and liquid and a single pump, the container a has a false bottom d, to the lower side of which is attached a valve box e provided with inlet and outlet pipes h, l. The pump a<2> passes through the bottom d into the valve box. The container is first charged with air by means of the pump, the air being drawn in through the pipe h, and ball valve f, and forced through a disc valve j<r> and a float valve k<5> into the container. The pipe h is then connected to a source of liquid, and the pump forces liquid into the container, the float valve k<5> rising with the liquid level. At the end of the discharge of the liquid through the pipe l, the valve k<5> prevents the compressed air from escaping. The under side of the valve j<7> is open to the pressure in the container through passages j<5>, j<8> in the valve seat to facilitate the charging operation.

Filed: 1955-11-17
Abstract: 816,712. Temperature-sensitive resistors. GENERAL ELECTRIC CO. Nov. 17, 1955 [Nov. 29, 1954], No. 32995/55. Class 37. A temperaturesensitive element comprises a mass of electrolyte, the resistance of which changes discontinuously at a predetermined temperature, preferably formic or oxalic acid, sandwiched between and in electrical contact with a pair of spaced conductive plates, the edges of which are separated by insulation. As shown in Figs. 1 and 2, block 14 of solid electrolyte, preferably with slightly convex faces, is located in a matching aperture 20 in insulating plate 22 between tin foils 8, 10 bonded to the plate by material applied to either the foils as at 16, 18, to the plate, or to both. The overlapping ends of the plate are then folded back over foils 8, 10 respectively and mounting brackets 4, 6 are crimped about them to form respective terminals of the device. Such elements may be mass produced by feeding forward a continuous apertured insulating strip past stations at which blocks 14 are inserted in the apertures and foils applied about them, to a heated press which fuses the electrolyte to the foils and bonds them to the insulating strip. As the completed element leaves the press it is severed by a knife on the leading edge of the press as the latter descends to form the following element. The element may be used in circuits for operating alarms or switching off heaters when the temperature exceeds a certain value.

Title: Improved method of and apparatus for spectrochemical analysis
IPC: G01N21/31
Filed: 1954-11-15
Abstract: 763,556. Radiation analysis. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Nov. 15, 1954 [Nov. 17, 1953], No. 33068/54. Class 40 (3). The concentration of an element or an isotope in a substance is determined by passing a beam of radiation containing an atomic spectral line characteristic of the element or isotope through the substance in the form of an atomic vapour which emits radiation, detecting the radiation and eliminating or compensating the effect on the detector of radiation emitted by the vapour. As shown, Fig. 2, radiation from a source 11, the spectrum of which contains a spectral line at the wavelength required for a particular analysis is split by a pair of reflecting surfaces 13a, 13b into two beams interrupted in antiphase by choppers 14a, 14b. The beams are reflected by concave mirrors 15a, 15b respectively, the first passing through an atomic vapour 16 of the substance to be analysed and the second through an adjustable attenuator 17. The atomic vapour may be produced by spraying a solution of the substance into a flame or by heating the sub. stance in a small furnace sufficiently to vaporize. Mirrors 18a, 18b then direct the beams through a monochromator 19 where the spectral lines of interest are selected. Radiation from the monochromator falls on a photo-electric detector 20, is amplified and rectified at 21 and indicated at 22. The chopping of the incident beams ensures that light produced by the vapour itself does not affect the detector. The attenuator may be adjusted to bring the detector output to zero when the attenuator position indicates the concentration of the element. The attenuator may be omitted and the ratio of the two beams measured directly. A single beam arrangement also is described (Fig. 1, not shown) while in the arrangement of Fig. 3 (also not shown) a pair of detectors are provided, one only receiving the analysing beam while both receive light emitted by the vapour. The cells are connected in opposition so as to eliminate errors due to the vapour. Chopping of the beams is here unnecessary. In the arrangement of Fig. 4 (not shown), a number of sources each corresponding to different spectral lines is provided. All the sources are associated with a concave diffraction grating and are so arranged that a spectral line produced by each appears in a single slit. Thus the lines may be selected by switching off or blanking off all except one of the sources.

Title: Improvements in aircraft wheel braking systems
IPC: B64C25/48
Filed: 1931-12-02
Abstract: 397,895. Aircraft wheel braking systems. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, GOODYEAR, E. F., WRIGHT, J., and TREVASKIS, H., c/o Dunlop Rubber Co., Foleshill, Coventry. Dec. 2, 1931, No. 33370. [Class 4.] A wheel-braking system for aircraft comprises fluidpressure-actuated brakes to which fluid is admitted upon movement of a finger lever mounted on the main flying control lever, movement of the rudder bar causing a differential application of the brakes only when such finger lever is moved. The finger lever may be provided with a locking ratchet to hold the brakes on for parking purposes. A finger lever on the main control column actuates a Bowden cable 12, Fig. 7, to move a quadrant 14 having a spherical end 15 engaging a link in a guide 23 carried by a bracket 19. The link is connected to a pin 22, normally coaxial with the cable 12, from which links 21 extend to two sleeves 28 in radiating valve chambers 25. Normally the guide 23 makes equal angles with the two links 21, but by turning the bracket 19 about a ball bearing 17a the slide 23 and the quadrant 14, which is mounted between cheeks 16 on the bracket 19 are turned also, so that movement of the quadrant causes unequal movements of the links 21. Each sleeve 28 as it moves into the valve casing compresses a spring 31 to move a hollow stem 30 against a valve 35 to close an exhaust passage through the stem and open a valve 38 to admit pressure fluid from a pipe 5 to a chamber 37. As the pressure builds up it presses on a diaphragm 33 to close the valve 38 when the pressure equals the initial compression of the spring. The chambers 37 communicate through pipes 7, 8 with the brakes on the two sides of the machine. The bracket 19 has an arm 18, Fig. 6, connected to the rudder bar. The pipes 5, 7, 8 are compressed on to nipples by screwed rings 43, 44 having tapered parts compressing lead packing rings 45. Additional relays in parallel planes may be employed when more than two brakes are to be applied, by extending the pin 22 and duplicating associated parts. The valves and actuating gear are identical with those described in Specifications 397,896 and 397,897. According to the Provisional Specification, where a hand-wheel control is employed the brakes may be applied by a ring displaceable relatively to the wheel. A modified valve relay also is described wherein the inlet port comprises an orifice in the side of a closed tube entering the valve chamber at right-angles to its axis, the orifice being controlled by a conical valve actuated by a sleeve moved by the stem 30. Specification 397,890, [Group V], also is referred to.
