Title: Improvements in or relating to rotary engines, pumps and the like
IPC: F01C11/00
Filed: 1948-05-19
Abstract: 653,185. Rotary engines and pumps. GOODYEAR, J. W. May 19, 1948, No. 13493. [Class 110(ii)] In an engine of the worm and worm-wheel type the rotor vane 25 is of gradually varying inclination relatively to the axis of the rotor 11 the rotor being curved longitudinally to conform to the peripheral curvature of the abutment disc 17, the rotor being of increased diameter towards at least one end. The cross-sectional area of the working space 24 may be constant or vary towards one or both ends to give compression or expansion of a fluid. One of two relatively moving parts such as 29 may be of rubber or the like, or lined therewith. Fig. 1 shows a pump with inlet port 21 and outlet port 23, though the pump may be reversed. The apparatus may act as an engine. Sealing members 30, 31 isolate the working chamber from the disc chamber 16. Fig. 4 shows a compressor in which fluid flows from an inlet 21 through a working chamber to an outlet 23. The rotor may be reversed and the apparatus used as an engine. The vane 25 meshes with slots 26 in a disc 17 and, the vane tip runs closely to the casing periphery 27. In Fig. 5 a vaned rotor 11 meshes with a disc 17 and working fluid enters an inlet 27, Fig. 1, is compressed and fuel infected at 39. The gases expand to drive the rotor and are exhausted through a duct 23 after flowing between turbine blades 49, 50 on the rotor and fixed guide blades 52. In addition, inlet moving blades 48 co-act with fixed blades 51. The rotor may carry more than one vane, and a rotor may co-act with two or more discs. An engine drive may be taken off the disc shaft. In a modification two axially-displaced discs of different diameters, Fig. 14 (not shown), mesh with vanes on one rotor to form an internalcombustion engine. Fig. 15 shows a further form in which the rotor 11 is shaped as an annulus with a convolute vane 25 which operates in a working chamber 38 and meshes with a slotted wheel 17. A cone 42, on the shaft 10, maintains the crosssectional area of the discharge channel 23 constant from the end of the rotor. A modified engine has two rotors axially spaced on the same shaft, each meshing with a slotted disc, fluid entering the rotors from the ends and being discharged through a common central outlet, this arrangement balances end thrust on the shaft. In a final example there are four rotors on two shafts with two discs between the shafts each meshing with two rotors arranged diametrically opposite each other. The fluid flows through the four rotors in series.

Title: Improvements in electrodes for use in electrolysis
IPC: C25C7/02
Filed: 1920-05-17
Abstract: 157,871. Chile Exploration Co., (Assignees of Fink, C. G.). Jan. 21, 1920, [Convention date]. Alloys.-An electrolytic electrode is made of an alloy containing cobalt and silicon. There may also be added a metal, such as manganese, facilitating disengagement of the electrolytic oxygen, and a hardening-metal such as chromium, tungsten, molybdenum, or uranium. Sufficient carbon may be added to produce a slight formation of graphite. Good results are got with the following composition:-11.5 to 13 per cent of silicon, 4-6 per cent each of manganese and chromium, 0.8-1.2 per cent of carbon, and the rest cobalt. From 5 to 30 parts of the cobalt may however be replaced by manganese, 5-12 by chromium, or 5-8 by nickel. The cobalt used may contain 4-7 per cent of nickel and iron as impurities. Maximum bending strength is obtained with 12-15 per cent cf silicon. Carbon should generally be between 0.5 and 1.2 per cent, silicon between 7 and 20 per cent, manganese between 3 and 45 per cent, and chromium or its equivalent between 4 and 10 per cent. The carbon in the form of charcoal may be added to the molten cobalt, followed by silicon and manganese. together. The addition of silicon produces evolution of heat, and should be gradual; carbide of silicon may be used, or the silicon mav be first combined with a small proportion of cobalt. Alternatively, mixed oxides of cobalt, manganese, and chromium may be reduced. The final alloy is stated to consist of particles of an alloy of high conductivity but liable to corrosion, enclosed in a substance, probably cobalt silicide, or low conductivity but high resistance to corrosion. The anodes can be used in solutions containing nitrates and chlorides, and at temperature up to 60‹ C.

Patent GB-457170-A (GB)
Title: Improvements in telegraph, signalling, and like selective systems and apparatus
IPC: H04L17/06
Filed: 1935-05-16
Abstract: 457,170. Type-printing telegraphy. SIMS, V., 143, Park Road, Hendon, London. May 16, 1935, No. 13801/36. Divided out of 454,553. [Class 40 (iii)] The member whereby the transmitting contact is controlled in a key board or tape transmitter, particularly one of the kind described in Specification 454,553, is actuated by mechanism in which a single cam projection for each signal element acts in conjunction with a corresponding pair of abutments. In a keyboard transmitter the depression of each keybar 2, Fig. 2, shifts selected permutation bars 1 so as to bring one or other of two abutments 3 under the corresponding arm of a three-armed lever 6. The series of threearmed levers are lowered in turn during the transmission of an impulse-combination by cam projections 9, one for each impulse, acting upon arms 4 which carry the threearmed levers. Each of the latter, on being turned by an abutment 3, acts upon one or other of a pair of transverse bars 11, 12 ; these are common to all the levers and are mounted upon end plates 13 to which the motion is communicated so that a member 18, common to all the signal elements, sets a movable contact 19. For the start and stop impulses the end plates are rocked by the direct action of cams 9 on arms 21, 22. In a modification, Fig. 3, instead of a single lever 4 for each signal element, two levers 29 bearing abutments 28 are raised so as to engage one or other corresponding abutments on a contactsetting lever 25, according to the position of the latter as determined by the permutation bar 1. The lever 25 is thus rocked about its pivot 26 so as to set a contact 19. The Specification describes five further mechanisms, Figs. 4 to 8 (not shown), whereby the contact 19 is actuated jointly by the cams 9 and permutation bars 1. Instead of the contact 19, a contact spring 65, Fig. 9, may be clamped between two stiff flat springs 62 whose distance apart is adjusted by means of a set screw 63 so that the contact spring 65 is slightly buckled and remains in the position to which it has been set by studs 70 on a contact-actuating member 60. The spring makes contact with one or other of two resilient contacts 66, 67.

Title: Method and device for determining spontaneous cross sectional variations in textile material
IPC: B65H63/06
Filed: 1959-04-21
Abstract: 899,827. Photo-electric control systems. ZELLWEGER Ltd. April 21, 1959 [May 9, 1958], No. 13607/59. Class 40(3). In an arrangement for determining abrupt cross-sectional variations in a textile yarn the latter 9 (Fig. 1) is drawn through two adjacent light beams associated with respective photo-electric cells 5, 10 connected in different arms of a balanced bridge circuit, the arrangement being such that the passage of an abrupt variation through one of the beams upsets the balance of the bridge. A signal derived from the latter is then utilized to operate a cutting device (Fig. 9, not shown) which cuts the yarn at the faulty spot. The Specification includes a mathematical analysis of the operation of the invention which considers the diameters, b, of the light beams and the spacing a between them for various "wavelengths" (related to the staple lengths) of the variations in cross-sectional area of the yarn. A constructional form of the apparatus allowing the distance a between the beams to be varied is described with reference to Fig. 8 (not shown). The control circuit for the cutting device may employ transistors (Figs. 9 and 10, not shown).

Title: Improvements in and relating to fluid pressure braking apparatus
IPC: B60T13/36
Filed: 1919-06-02
Abstract: 145,953. Westinghouse Brake Co., (Westinghouse Air Brake Co.). June 2, 1919. Fluid-pressure.-Combined straight and automatic systems, in which a brake equipment is supplied at each end of a locomotive, have in each equipment a transfer valve device so arranged that when the driver's valve is applied at one end to supply fluid to that brake cylinder, some of the fluid is supplied through the transfer valve to the distributing-valve of the other equipment to operate the other brake cylinder. The cut-out cocks 32 in the positions shown make the left-hand half of the equipment responsive to the left-hand valves. Main reservoir 4 is thus connected both through feed-valve 5, automatic valve 24 and cock 32 to brake pipe 18, and also to chamber 30 and piston 29 of the transfer valve 7, whilst chamber 28 is exhausted through pipe 33 and cock 32. The piston 29 is thus retained in the position shown, where it connects the straight-air valve 27 through pipes 36, 38 with the usual distributing-valve 1. When the straight air valve 27 is operated. fluid from the reservoir 4 is supplied through a reducing-valve 6, valve 27, pipes 36, 38, to piston 8 which is then moved with the application valve 13 to supply fluid to the brake cylinder 3. Fluid is also supplied through pipes 12, 34 to the right-hand transfer valve 7. Owing to the position of the right-hand cock 32, chamber 28 is supplied with fluid which, with the spring 40, moves the piston 29 to connect pipe 34 with the right-hand distributing-valve 1. The fluid in pipe 34 thus operates this valve to supply train reservoir fluid direct to the other brake cylinder 3. When the valve 27 is turned to vent fluid from the lefthand valve 1 and left-hand cylinder 3, fluid is also vented from pipe 34 and right-hand valve 1, and thus from right-hand cylinder 3. Chokeplugs 44, 45 are inserted in the main reservoir pipe 15 and equalizing pipe 34 to prevent undue loss of fluid from the main reservoirs and brake cylinders, respectively, in the event of a parted hose connexion.
