Pumping-machines.-A wet vacuum pumping-apparatus has a. horizontal tank A, for receiving the returns, connected to a forwardly extending tank D, to either or both sides of which a pumping unit F can be attached. Each unit has a water impeller K, Fig. 9, and air pump rotor I driven by an electric motor L. The electric motors driving the pumps are controlled by rise of liquid or of gas pressure in the tanks. The tank A has a strainer B at one end, a water gauge C at the other, and two feet a. The tank D rests on the ground and forms a third support. Two opposite sides of the tank D are each formed with passages 10, 11, Figs. 3 and 9, leading air from the tank to the pump I and from this, through a non-return valve Q, to an upper tank D<1> open to the atmosphere. The sides are also formed with separate or integral volutes E and connected by a dam O. When separated water rises in the tank D', the float R opens a valve and allows it to flow into the tank D. Each motor has a starter Y, Fig. 1, the switch of which is operated by the rise of a float T, Fig. 3, or of air pressure acting through a vacuum regulator, not shown, the floats preferably being arranged so that one unit starts first and the second only starts if the first cannot deal with the incoming water &c. fast enough. When only one unit is fitted the other opening in the tank D and the opening in the tank A for the float supports are closed by cover-plates. If a valve Q requires attention a cover 13 is removed. Specifications. 192,365, 200,150, and 280,779 are referred to.

Title: Improvements in or relating to the suspension of automobile and other vehicles
IPC: F16F9/24
Filed: 1922-10-21
Abstract: 189,754. Ram, G. H. E. de. Dec. 5, 1921, [Convention date]. Dash-pots. - A spring suspension for motorvehicles &c. comprises two springs of different flexibility, or a spring having two parts differing in flexibility, in combination with a brake or damping device of the liquid type which progressively suppresses that action of the weaker spring, or part thereof, so that the flexibility of the suspension decreases when the speed of the vehicle, and consequently the rapidity of the shocks, increases. In the application to a coiledspring suspension, shown in Fig. 3. a bell-crank lever 15, 16, secured to the axle 2 and pivoted to the chassis at 21, is connected by a link 17 to a disc 18 which moves in a fixed cylinder 22 against the action of springs 19, 19' separated by a piston or disc 20. The spring 19<1> is the weaker of the two, and that portion of the cylinder in which it is located constitutes the braking device. In the modification shown in Fig. 4, the springs 19, 19' are arranged in parallel between a pair of members 25, 26 pivoted respectively at 27, 28 to the lever 23 and chassis. In a further modification shown in Fig. 5, springs 33, 34, of which 33 is the weaker, are enclosed in a chamber secured to the chassis and are respectively acted upon by a floating piston 32 and a piston 31 connected to the axle. Rising movement of the axle causes liquid to flow from the space between the two pistons through a port in the piston 31 and a valve-controlled by-passage at the top of the chamber. If the movement is a slow one, it will be communicated by the spring 34 to the piston 32 and spring 33, the liquid in the chamber containing the spring 33 flowing substantially freely through a port in the piston 32. If the movement is more rapid, the action of the spring 33 is suppressed since the port in the piston 32 is not sufficiently large to permit passage of liquid at the required speed. At the commencement of the movement of the piston 32, the end portions for the left-hand end and centre portion of the chamber are in communication by means of a valve-controlled by-passage at the bottom of the chamber. The piston 31 may be arranged to slide in the piston 32.

Abstract: 305,499. Lynden, Robert Aernout, Baron van. Oct. 29, 1927. Fluid speed indicators.-In indicating-apparatus of the kind in which a swinging member is exposed to the action of two oppositely acting forces both of a dynamic nature and derived from fluid movement, the fluid movements are set up by a common originating movement or two independent originating movements, the arrangement being such that variations' in the originating movement or movements result in dissimilar variations in the two forces. The apparatus may be used as an aircraft turn indicator, or as a speed indicator. In the form shown in Fig. 1 fluid set in motion in a conduit A by a propeller B driven by the body the speed of which is to be measured, or set in motion by the movement of the apparatus through air or water, flows through conduits C, D. The former ends in a nozzle C<1>, and the latter is spaced from a conduit D<2> ending in a nozzle D<3>, the nozzles being opposite shaped flanges of members E, E<4> on the shaft of an indicating member. In a modification, the apparatus comprises conduits F<2>, F<3>, Fig. 2, differently spaced from the conduits G, G<1> ending in converging nozzles G<2> spaced from tubes ending in nozzles H<3>, H<4> opposite shaped members on the indicating shaft. In both forms, the fluid streams may be originated by a turbine disc and a smooth disc on a common shaft. In a further form, the two streams are originated by a turbine disc L<2>, Fig. 5, the first stream passing through openings M<1>, M<2> to act on a member N<1> on the indicator shaft and the second passing between a revolving drum L<3> and its enclosing casing and thence to an opening M<6> to act on a member N<2>. If desired, the fluid streams may be of an intermittent or pulsating character; the apparatus may then comprise a cam-operated vibrating member O<1>, Fig. 6, conduits P<3>, P<4> differently spaced from an annular chamber Q<3>, and a vane Q<4>.

[Class 40 (iv).] In a system employing code-translating register controllers, zone metering is effected in accordance with the position of a vertical wiper on the 1st code selector during conversation. Seizing and controlling 1st code selector. Line relay L starts a call finder which in known manner extends the call to the circuits of the 1st code selector in which 1L pulls up, followed by B, 1A, I, 1C, MG, the last interacting with the driving magnet RXM of the switch RXF until an idle registercontroller is found whereupon MG is shunted by the marking battery and 2K switches through, energizing the impulse relay of the register controller over the right-hand winding of B. When the 1st routing digit is received from the register-controller, 1A repeats it to the vertical magnet 1VM. Owing to the change-over of springs 1N1, 1C falls at the end of the digit and gives an impulse to the rotary magnet 1RM. If the upper trunk is busy, 1G pulls up at the end of the stroke over the upper test wiper, locks and releases the magnet, but if the lower trunk also is busy at once short-circuits itself over the lower test wiper. If the upper set finds an idle trunk, 1HA switches through, if the lower, 1HB switches through when 1G pulls up. Metering. Supervisory relay D starts the operation of " S " and "Z" relays DA, DB, the latter of which locks itself into the holding wire and connects J to a wire selected by the vertical wiper 1VW and carrying a characteristic number of metering impulses. At the end of the "Z" pulse, DA releases J which cannot be operated again. J repeats the metering impulses by connecting reverse battery to the 3rd wire. Between impulses, the meter is short-circuited. Release. When ground is removed from the holding wire there is a circuit via the meter for energizing the windings of cut-off relay K in opposition.

Title: Braking control apparatus
IPC: B60L7/24
Filed: 1972-06-21
Abstract: 1412451 Vehicle braking systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 8 June 1973 [21 June 1972] 29177/72 Heading F2F A braking control apparatus for a rail vehicle comprises a blending valve 6 responsive to both a D.C. signal from a rectifier 9 having input terminals connected to receive an A.C. signal indicative of the degree of electrodynamic braking and an output braking demand signal from a digital or analogue control valve apparatus 4 whereby the blending valve 6 output pressure signal represents the braking force required to achieve the demanded retardation with the amount of electric braking produced being subtracted from it. In operation, signals appearing in lines 1, 2 and 3 running the length of the train are converted into a pneumatic pressure in a conduit 5 fed to blending valve 6 which also receives a pressure from an electropneumatic converter 8 receiving the D.C. signal. The circuit in Fig. 3 represents rectifier 9. When electrodynamic braking starts an A.C. input is produced at terminals 11, 12 and an e.m.f. appears in windings 17, 15 of a transformer provided with a core 16. A rectifier bridge 18 is caused to conduit to energize transistors 22, 23 whereby current is supplied to converter 8 via terminals 20, 21. A capacitor 30 is also charged and transistor 24 switched on thereby switching off transistors 25, 23, 22. Since the number of turns of winding 17 is half that of winding 15 a doubled output current appears at terminals 20, 21. Thus the amplified dynamic brake signal results in a boosted signal in conduit 7 thereby holding back the rise of pneumatic braking. After a time interval determined by the time constant of capacitor 30 and a resistor 32 the base current to a transistor 24 ceases, the latter then being turned off. Consequently, transistors 25, 23, 22 are rendered conducting and the current supply to terminals 20, 21 is therefore halved. Current produced by a current transformer 13 is rectified via a diode bridge 38 and charges capacitors 42, 40. Thus when the input current at terminals 11, 12 decreases at the end of dynamic braking capacitor 40 discharges via a transistor 27 the latter becoming conducting to render a transistor 26 conducting to carry a current whose magnitude is determined by a Zener diode 36. Transistor 26 thereby becomes a constant current device causing a predetermined amount of current to be diverted from terminals 20, 21. Hence the pneumatic brake is caused to respond more rapidly. A circuit is described, Fig. 4 (not shown), which ensures that the boost circuit does not operate when subjected to a sharp rise in dynamic braking when a smaller value of dynamic brake load resistance is selected by a cam controller controlling the braking current.
