Title: Improvements relating to train brake control apparatus
IPC: B60T7/18
Filed: 1924-01-18
Abstract: 225,725. Haddan, R., (Regan, J. B.). Jan. 18, 1924. Fluid-pressure. - In a valve mechanism for track control of train brakes, including regulating-means on the exhaust from the brake control valve to limit the reduction of train pipe pressure, the regulating-means comprises a pair of diaphragms, subject respectively to train-pipe pressure, and either main reservoir pressure or a variable pressure, and an adjustble spring for regulating the pressure at which the exhaust of the train pipe ceases. When the mechanism is actuated by the de-energization of an electromagnet the main reservoir is cut off from the driver's valve. As shown in Fig. 1, the pipe 9 from the driver's valve is normally connected to the main reservoir by the pipe 8 through a valve 7, and the train pipe, connected at 14, is cut off from the exhaust pipe 15 by a valve 13, the underside of a diaphragm 18 being subject to main reservoir pressure through a pipe 22 and passages shown, a valve 20 being held open by an electromagnet 21. When, however, this magnet is de-energized, the valve 20 is closed, and the chamber 19 is opened to atmosphere at 25 by a valve 24, so that main reservoir pressure acting on a smaller diaphragm 17 closes the valve 7 and opens the valve 13 to connect the pipe 14 to the exhaust 15 and the regulating- valve B. This latter comprises diaphragms 27, 31 carried by a stem 30 provided with a valve 29 controlling the exhaust 28, the smaller diaphragm 31 being subject on its underside to main reservoir pressure through a pipe 33 and to the pressure of an adjustable spring 34. Normally the valve 29 is held closed, but when the pipes 14, 15 are connected, it is opened by trainpipe pressure acting on the 'arger diaphragm 27, and remains open to exhaust the train pipe until the combined upward pressures on the diaphragm 31 are sufficient to overcome the reduced trainpipe pressure on the diaphragm 27. In the modification shown in Fig. 2, wherein provision is made for a predetermined reduction of pressure irrespective of the train-pipe pressure, a diaphragm 37 controlling an exhaust valve 39 is subject on its upper face to the pressure in the pipe 15 and to the pressure of an adjustable spring 40, whilst a diaphragm 45 is subject on its under face to the pressure in the chamber 19 through a pipe 43 and carries a valve 47 controlling communication between chambers 48, 49, the latter of which is connected by the pipe 50 to the train pipe. In this form, the under side of the diaphragm 45 is normally subject to main reservoir pressure, and the valve 48 is held open, so that train-pipe pressure acting on the under side of the diaphragm 37 holds the valve 39 closed. When, however, the electromagnet 21 is de-energized and the chamber 19 exhausts the diaphragm 45 drops to close the valve 47, so that air at the initial train-pipe pressure is trapped in the chamber 48, and exhaust through the valve 39 will be effected to a degree determined solely by the setting of the spring 40.

Abstract: 596,310. Thermionic valves; sawtooth generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and ROGERS, D. C. Jan. 23, 1945, No. 1797. [Classes 39 (i) and 40 (v)] A thermionic valve comprises two pentode valve sections having separate unequal anodes 6, 7, Fig. 1, but the control grid 3, screen grid 4 and suppressor grid 5 being common to the two sections and interposed between the cathode 2 and the anodes 6, 7 and the electron collecting areas of the anodes 6, 7 are so proportioned that the anode currents and mutual conductances of the two sections are in a specified constant ratio while the control grid potential is varied over a specified range. Preferably, the currents collected by the anodes 7, 6 are in the ratio of 10 : 1 respectively. The cathode 2 may be in the form of a hollow metal cylinder containing a heater and is then surrounded by cylindrical wire-wound grids 3, 4, 5 and by a hollow anode cylinder which is divided into two unequal parts by a cut transverse to the axis, Figs. 3, 4 (not shown), an annular metal screen 8 being interposed between the two anode parts 6, 7 and electrically connected to the cathode 2. A " diode anode " 9 may be placed near the cathode 2 and connected to the suppressor grid 5. The valve may be used in a circuit for generating saw-tooth waves, as shown ; the circuit does not oscillate spontaneously, but has to be triggered by applying pulses of rectangular waveform between the terminals 18, 20. The current in the circuit connected to the smaller anode 6 is consequently of saw-tooth waveform and an amplified copy of this waveform is produced in the circuit connected to the larger anode 7, and may be applied to the deflecting coils 16 of a cathode-ray tube through an output transformer 15.

Title: Improvements in package feed devices in packaging machines
IPC: B65B43/54
Filed: 1961-01-06
Abstract: 910,633. Endless and rotary conveyers. HESSER, MASCHINENFABRIK-A.G., FR. Jan. 16, 1961 [Jan. 16, 1960], No. 1806/61. Class 78 (1). [Also in Group XVII] In a packaging machine an intermittently moving conveyer device has spaced package holders, each of said holders having walls or parts which define an open-ended package closure and are mounted for simultaneous movement away from the enclosed package, to release the same temporarily, at a station in the travel of the conveyer device. The device may be a rotary or a chain conveyer. In one embodiment, Figs. 1, 2 and 4, a horizontal disc 1 has pairs of holder walls 3 pivotally mounted on its underface. A rear wall 4 is mounted between each pair of walls 3 by means of bearing blocks 10 which allow it to move freely in a radial direction. Pairs of rollers 11 ensure by coacting with shoulders 28 that the walls 3 move apart to release the enclosed package simultaneously with inward radial movement of the wall 4. The packages 2 are moved over a fixed annular support plate 6 to a filling device at a station I, to a control weigher at a station II and thence past an ejecting station III. The filling device and the control weigher are of known construction. The packages are released temporarily for weighing at the station II by a cam 22 (Fig. 2) being rotated while the disc 1 is stationary and coacting with a roller 23 to cause inward radial movement of the rear wall 4 (Fig. 2). After weighing the package is re-gripped and moved on past the ejecting station at which packages of faulty weight are ejected. A control device which regulates the filling device in response to alterations in the weight of the packages is provided. The ejecting device (Fig. 4) comprises a block 29 radially movable by a solenoid 32. When the roller 23 enters a groove in the block solenoid 32 is operated to move the block 29 outwards this causing outward movement of the wall 4 which ejects the package. In a modification, a chain conveyer having package holders as shown in plan in Fig. 7 is used. These comprise angled plates 41, 42 mounted on bell-crank levers 43, 44 pivoted at 45, 46 to the chain and operatively connected to a bell-crank 47. This mechanism is held in the full-line position shown by means of a spring 49 and a stop 50, but rotation of the crank 47 in the direction a causes the plates 41, 42 to move to the chain dotted position to release the package. The rear wall forming portion of the plates are recessed to allow for the passage of an ejecting plunger (Fig. 8, not shown). This type of package holder may be used on a rotary conveyer.

Title: Production of useful combustible gas from caking bituminous fuels
IPC: C10J3/08
Filed: 1953-01-27
Abstract: A mixture of finely-divided coking coal and ore of a still finer grain size is coked and the metalliferous product, freed from fine grains which may be returned to the ovens, gasified in a low shaft furnace operated as a slagging producer with air or oxygen with or without steam, carbon dioxide, &c., metal and slag being separately withdrawn in fluid state.  Heavy mineral or tar oil, pitch, asphalt, &c., e.g. about 1-3 per cent by weight, may be added to the mixture to be coked.  If the coke is gasified with oxygen and preheated steam the gas may be carburetted or methanized to yield a town gas and mixed with the coke oven gas. Coals giving an insufficiently hard coke may be mixed with under 3 per cent of ore of the highest oxidation stage and heated to 10 DEG  C. or more before coking.  The air blast may be heated by the gas produced which may be used for underfiring the coke ovens, or, with a reduced demand for coke oven gas the total amount distilled may be compressed and freed from benzene, the proportion not required then being diverted to the ovens.  The coal with a grain size below 5 mm. and preferably below 2 mm. may amount to 50-80 per cent by weight of the mixture and the ore grains are preferably below 1 mm.  The coke may have an iron content of preferably about 30 per cent.  In an example, a gas-rich coal coked with iron ore contains 60 per cent of coke lumps of 60 mm. and 33 and 7 per cent respectively sized above and below 10 mm.  The largest sizes may be introduced into normal blast furnaces and the remainder above 10 mm. gasified in the producer.  Carbon dioxide may be supplied to the glowing coke in the oven to increase the quantity of gas released.
