Title: Fluid flow dividing device
IPC: G05D11/02
Filed: 1957-06-19
Abstract: 838,428. Valves. NEW PRODUCTS CORPORATION. June 19, 1957 (Nov. 23, 1956], No. 19377/57. Class 135. A fluid-flow dividing device 10, Fig. 1, has an inlet 46 connected to an engine-driven pump 17 and two outlets 12, 13 through which fluid is supplied to cylinders 23, 29 for operating the lift mechanism of farm tools or earth-moving equipment and the steering mechanism of the associated vehicle, respectively. The device comprises a casing 33 in which is a sleeve 35 closed at one end by a plug 37 that has lugs 40 that define its position within the casing upon screwing in a fitting 11 forming the inlet 46 and embodying a flange 52 which is deformed by contact with the sleeve 35 to form a fluid-tight joint therewith. The sleeve 35 incorporates two sets of radial ports 59, 88 and an inwardly extending adjustable pin 60, whilst between the sleeve and casing two annular spaces 39, 44 are provided. Slidable within the sleeve is cup-shaped valve closure 47 with an inlet orifice 58, the closure being loaded to the position shown by a spring 57. The pin 60, which is adjusted so that it is contacted by closure 47 before ports 59 are closed, has a step ground on its end face. Space 44 which interconnects outlet 12 and ports 88 also leads to one end of a chamber 64 from which opens a vent outlet 14, the other chamber end being in communication with the other annular space 39. At each entry to the chamber 64 is a ball closure 68 and between this closure is a spring 73 prevented from buckling by a pin 74, and adjustable via a screw 69. The areas of the valve seats may be different to provide different limiting pressures for each fluid stream. In another form each annular space is connected to the vent 14, Fig. 3, by a separate lift valve 80 with a through bore 87 that prevents pressure build up behind the valve in a recess 84 that houses a spring 83; the valve operating point may be adjustable. Pressure fluid in the inlet 46, Fig. 1, moves the closure 47 to the right to commence uncovering ports 88 and closing ports 59; the greater the pressure in the inlet 46 and outlet 12 the greater is the restriction to flow brought about by nearness of the pin 60 to the orifice 58, but due to the step on the end of the pin 60 flow to the outlet 13 is never cut-off. The pressure also builds up in the closure 47 when the flow through the outlet 13 is substantially zero, the closure assuming a position wherein the fluid and spring forces acting on it are balanced. When the power steering is in operation, the pressure builds up in the closure 47 to move the latter leftwardly until it reaches a balanced position with the ports 88 partially closed and a greater flow taking place through ports 59. Specification 829,145 is referred to.

Title: Improvements in or relating to impulse circuits in railway axle-counting installations
IPC: B61L1/16
Filed: 1957-06-20
Abstract: 819,400. Counting-apparatus. SIEMENS & HALSKE A.G. June 20, 1957 [June 22, 1956], No. 19463/57. Class 106 (1). [Also in Group XXXIX] An impulse circuit in a railway axle-counting installation includes a choke whose core has an approximately rectangular magnetization loop, the choke having at least two windings to which impulse series generated by the passing of train axles and dependent for their time relationship upon the direction of motion of the axles can be applied in such manner that, as each axle passes, current is transmitted first to one winding to magnetize the choke to saturation, then to all windings when the effects of the impulses cancel one another out, and finally to another winding to magnetize the choke to saturation in the other direction, the voltage set up at the windings when a certain one of the impulses ceases serving to control the emission of a counting-in or counting-out impulse. In the circuit shown in Fig. 1, a passing axle causes the successive closure of contacts 1, 2 (or corresponding transistor switches) to cause current to flow through opposed windings 6, 7 of the choke 5. Fig. 2 indicates the potentials at correspondingly referenced points when an axle moves in such a direction as to close contacts 1 first at time t1 Assuming that choke 5 is in the negative saturation condition, the potential + U2 at point 3 causes current flow in winding 6 which changes the choke core to positive saturation thus inducing a pulse in winding 7 which reduces the potential at point 4 to - U2 and, through condenser 11 and resistance voltage divider 12, 13, produces at point 19 at the base of transistor 15 a negative pulse but of value U3 insufficient to cause the transistor to conduct. When contacts 2 close at time t3, the currents in 6, 7 cancel one another out and do not affect the core, but when contacts 1 subsequently re-open at t 4 , the current in 7 alone changes the core from positive to negative saturation thus taking point 3 from + U2 to - U2, and therefore produces at point 18 and the base of transistor 14 a negative pulse of value 2 U3, whereupon the transistor conducts and produces a positive counting-in pulse at terminal 20. If an axle passes in the opposite direction, a positive counting-out pulse will be similarly produced at terminal 21. In a modification (Fig. 3, not shown), the contacts associated with windings 6, 7 are normally closed and are opened by the passage of an axle, and the transistor base circuits comprise transformers and rectifier AND gates. Other modifications are referred to; e.g. the arrangements for evaluating the voltages set up at the choke windings may be omitted if the counting mechanism is such as will respond only to negative impulses > U3 at points 18, 19.
Patent GB-195058-A (GB)
Abstract: 195,058. Gauthier, E. W. March 17, 1922, [Convention date]. Timing devices; centrifugal actuation.-In interrupters provided with centrifugal means for automatically varying the point of ignition in accordance with the speed, a weighted arm 9 pivoted at 7 on the plate 1 swings outward against the action of the spring 10. The lever 9 has an arm 26 working in a slot 25 in an arc-shaped carrier 24 which moves between curved guides 23, 27 projecting from the plate 1. A member 21 passes transversely through the carrier 24 and through a guide slot 22 in the projection 23 and when depressed by relatively fixed cams during the rotation of the interrupter by acting on the tail 15 of the interrupter lever 12 pivoted at 8 causes interruption of the primary circuit at contacts 6, 13. Centrifugal outward movement of the arm 9 varies the point at which the member 21 is engaged by the fixed cams, so varying the ignition timing. In a modification, Figs. 3 and 4, the end 26 of the lever 9 acts directly on the lever 21 which when depressed by the fixed cams raises the blade-spring contact lever 30. The lever 21 has an elongated slot 33 loosely surrounding the sleeve 34 on the central securing bolt 3 to permit angular movement against the spring 36 for timing purposes and axial movement for operation of the contact breaker.

Abstract: 1,146,204. Laminates. STEPHENSON, MILLS Ltd. 27 April, 1967 [5 May, 1966], No. 19849/66. Heading B5N. [Also in Division D1] A method of producing a laminated fibre product comprises combing and distributing fibrous material consisting at least in part of animal hair to form a lap or batt 11, treating it with a bonding agent in one or more stages 14, 21, to permeate the thickness of the lap or batt and to bond adjacent fibres at points where one fibre crosses another, allowing partial curing or setting of the bonding agent to occur, e.g. by passing the lap through a heat treatment chamber 15, and then subjecting superimposed layers of the fibrous product, after cutting it into sheets, to pressure in a press to continue the curing and setting of the bonding agent. The fibres are preferably a blend of hog's hair and coconut fibre and the bonding agent, which is sprayed on the lap, is preferably a natural or synthetic rubber latex or other elastomeric dispersion with fillers. A phenolic resin may also be added. Organic and inorganic colouring pigments may be added. By varying the proportions of bonding medium from the sprays 14 and 21 and the pressure of application a migration of fibres may occur so that one side of the lap is denser than the other. In an embodiment, pressure is effected such that the laps or batts retain their separate identity and a pair thereof having varying density across their thickness are joined on their less dense surfaces 31.

Abstract: 1,095,130. Metal-vapour lamps. F. & M. SCIENTIFIC CORPORATION. May 12, 1965 [May 18, 1964], No. 19945/65. Heading H1D. The filling of a discharge tube for spectroscopic use includes a halogen of the metal whose spectrum is desired, together with mercury, the total pressure at the operating temperature being less than one atmosphere. To produce aluminium spectral lines, aluminium iodide, mercury-in an amount which is completely evaporated at the working temperature-and 5 torr. of argon, are employed, to give a total operating pressure of 32 torr. The restriction upon the operating pressure, together with use of a current limiting ballast resistor, prevents excessive broadening of the spectral lines. Spectral metals referred to, for introduction as a halide, include sodium, potassium, calcium, magnesium, and zinc. The envelope is initially outgassed by evacuation, gas torching of the interior, and a discharge in pure argon or neon at the highest current possible without melting the electrodes.

Title: Improvements in or relating to instruments for indicating or recording the relationship between variables
IPC: G01L7/00
Filed: 1943-12-01
Abstract: 575,008. Mechanical relay and follow - up devices. K.D.G. INSTRUMENTS, Ltd., and EVERINGTON, G. D. Dec. 1, 1943, No. 20101. [Class 118 (ii)]. [Also in Group XIX] A required relationship between variables is measured by an instrument comprising a pivoted lever, means responsive to each of the variables to produce forces proportional thereto, means for applying these to the lever to produce turning moments thereon, external adjusting means to vary one of the moments to balance the lever, and means for measuring the adjustment made. In An instrument for use in aircraft, for indicating the " Mach " number and comprising a lever 10 pivoted at 11, a sylphon bellows 40 acts directly on the lever and a sylphon bellows 41 acts indirectly thereon through levers 47, 13 pivoted at 48, 14. When the balance is upset, one or other of the contacts 59, 60 is made to produce rotation of the motor 58 in the required direction to move lever 13 longitudinally to restore the balance. The corresponding " Mach " number is read on scale 37. The interiors of bellows 40, 41 are subjected to air stream pressure P and a vacuum respectively. The exterior of the bellows is subjected to static air pressure S. The variables are therefore P-S and S. The ratio P-S/S varies in accordance with a function of the "Mach " number M and is approximately proportional to M<2>. The length of the lever 13 equals the distance between the end of lever 47 and the pivot 11. If y is the distance between the ends of levers 47 and 13 and pivots 14 and 11 respectively, then P-S/S is proportional to ye. Adjustments of 13 are therefore proportional to M.
