Title: Improvements in or relating to pneumatic-hydraulic spring means
IPC: B60G17/04
Filed: 1957-10-01
Abstract: 816,786. Road vehicle spring suspensions; hydropneumatic springs. EHRENREICH & CIE, A. Oct. 1, 1957 [Oct. 12, 1956], No. 30684/57. Classes 108(2) and 108(3) In a hydro-pneumatic spring unit comprising a cylinder and a piston, one of which is connected with the underframe and the other with the wheel of a vehicle, one face of the piston acting through a column of liquid on a volume of gas which is compressed in a chamber of variable capacity and which acts on one end of the cylinder, the other face of the piston determines the volume of a chamber at the other end of the cylinder in such a way that the piston and this latter end of the cylinder co-operate to form a pump for the displacement of a hydraulic liquid in a pipe system which is in communication with the column of liquid, the unit being thus selflevelling. When the vehicle is stationary, pistons 9, 10 enclose a volume of oil which is determined by the setting of valve 24 which also determines the ground clearance b of the vehicle. Under load, gas cushion 11 is compressed and its volume reduced simultaneously, valve 24 opens to permit oil to flow from accumulator 19, which contains compressed gas in space 29, through channels 18, 25, 15 into chamber 12 until the original ground clearance is re-established, when valve 4 closes again. Wheel deflections of short duration do not cause changes in ground clearance to be made since valve 24 is not open long enough. If the rise and fall of the wheel is slow there will be transfer of oil from accumulator 19 to chamber 12 and back again. Reciprocations of piston 10 draw oil from sump 21 into chamber 13 through pipe 16 via non-return valve 20 and force it back through pipe 16, non-return valve 17 and pipe 18 to accumulator 19. Pipe 7 takes hydraulic fluid to other accessories requiring hydraulic power. Initial inflation takes place through valve 14. Adjustable non-return valve 22, preferably dashboard mounted, provides a means of adjusting the damping characteristics of the system by varying the oil pressure in the accumulator.

Title: Magnetic Recording and Reproducing Apparatus
Inventor: KOZU ISAO
IPC: G11B15/22
Filed: 1968-07-01
Abstract: 1,183,287. Magnetic recording and playback. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 1 July, 1968 [30 June, 1967], No. 31402/68. Heading G5R. A reel-to-reel tape transport includes means under the control of an operator which changes a magnetic head from a playback to a recording condition and simultaneously causes a displacement means to engage one of the reel carriers and start responding to the tape movement, the tape being later rewound (when recording has ended) until it reaches the point at which the operation of the displacement means was initiated, when the displacement means is disengaged from the reel carrier and the rewind drive is disabled. As described, a tutor's recordings on one track (201, Fig. 6) are played back by a corresponding head (196, Fig. 5), there being no erase head for this track. A student uses further heads (198, 200) to record, play back, and erase on a second track (203), during the gaps in the tutor's recording. When the student presses the " record " button 166. Fig. 2, a solenoid 162 is energized to bring a roller 112 into engagement with the supply reel carrier 12 which is rotating anti-clockwise, so that a disc 116 starts rotating clockwise, releasing an arm 146 to operate a switch 154 which holds the solenoid 162 energized and prepares a circuit for a second solenoid 96 (Fig. 8). On completion of his recording, the student releases the button 166, completing an energizing circuit for the second solenoid 96 which initiates fast rewind, freeing the heads 16, 18 and pinch roller 34 from the tape, releasing drive roller 62 from the take-up reel carrier 20, and applying drive roller 78 to the supply reel carrier 12. Roller 112 and disc 116 are driven backwards until, when the starting position is reached, the arm 146 opens the switch 154 to de-energize both solenoids so that the student's recording is then played back to him.

Title: Integrated fuel injection pump and ignition distributor assembly
IPC: F02M57/00
Filed: 1968-07-02
Abstract: 1,205,854. Speed governors. FORD MOTOR CO. Ltd. July 2, 1968 [July 3, 1967], No.31445/68. Heading G3B. [Also in Division F1]  In a fuel injection pump and ignition distributer integrated in a single unit, changes in fuel flow and spark advance are effected as functions of the engine speed and load by a mechanical governor and a throttle lever respectively. An axially movable drive-shaft 26, in a bore 25, is drivingly connected to an injection pump, an ignition drive shaft 22, and a governor assembly 18. Fuel flow to the pump is controlled by a helix 58 on a valve 60 rotatably mounted about the shaft 26, further sleeves 74, 76 being intermediate shaft 26 and valve 60. Drive-shaft 26 and valve 60 and sleeves 74 and 76 are connected by a pin 78 Figs. 5, 6, 7, 8, (not shown) a pin 120 connected valve 60 and sleeves 74 and 76 Figs.12, 13, 14, (not shown), and a pin 112 Figs.9, 10,11, (not shown) drivingly connects shafts 22 and 26, and the sleeves 74 and 76. The sleeve 76 rests against a ball bearing unit 100 of the governor assembly and is separated from sleeve 74 by a spring 88, a weaker spring abuts a flange 92 on sleeve 74 and a washer 94 on shaft 26, a further spring 96 is intermediate the washer 94 and part of the housing 1. On depressing a throttle lever 144 connected to the distributer drive-shaft 22, the shaft 22 is moved upwardly and a pin 128 moving in slot 130 Figs. 3 and 4 (not shown) causes rotation of the sleeve 132 relative to shaft 22 and the ignition timing is advanced. Simultaneously shaft 26, valve 60, and sleeves 74 and 76, and the governor are raised, and helix 58 blocks the pump inlet part 52 f or a maximum period to ensure maximum fuel delivery through an outlet valve 54. Release of the throttle, with the engine running, lowers the governor which then acts to maintain an idling speed, the governor forces sleeves 76, 74 and valve 60 downwards, against the action of spring 90 when the speed increases above the idling speed so allowing relatively more fuel to spill back into bore 24. Decrease in speed reverses the motion of the sleeves. The accelerator lever may be used to increase the engine speed above the idling speed. When the engine speed is such that sleeve 74 is fully bottomed against washer 94, the governor acts to overcome the spring 88 and forces sleeve 76 downward relative to sleeve 74, causing valve 60 to rotate relative to drive-shaft 26, by the action of pin 78, and so advance the timing of injection, simultaneously the distributer shaft 22 is rotated relative to shaft 26 by the action of pin 112 and advances the ignition timing.

Filed: 1970-06-30
Abstract: 1312378 Electrolytic furnaces MONTECATINI EDISON SpA and G DE VARDA 30 June 1970 [30 June 1969] 31513/70 Heading H5H To prevent freezing of the bath 6 of a multicell electrolytic aluminium furnace a cathode 3 extends into the aluminium collecting pit 2 in the furnace bottom so as to provide good thermal and electrical conductivity between the cathode 3 and the vat bottom through aluminium collecting in the pit 2. As shown the cathode 3 is provided centrally in a furnace with a stepped bottom between terminal anodes 8 and bipolar electrodes 5. The distance between the end of cathode 3 and pit bottom 9 is such that even immediately after tapping the residual aluminium engages the cathode. The cathode being of carbon is a good thermal conductor and therefore heats the aluminium in pit 2. If the lower layers of the bath 6 are subjected to cooling during electrode renewal, furnace starting or current interruption, the heating of cathode 3 is increased by disconnecting some of the iron current supply bars 10 by means of switches 11 from the cathode, so that the resistance of the iron-carbon interface increases and the cathode 3 and hence the aluminium in pit 2 is heated more.

Title: Improvements in pneumatic apparatus for raising and forcing liquids
IPC: F04F1/06
Filed: 1919-12-16
Abstract: 144,565. Janney, W. E., Fiscel, H. E., Miller, J. L., and Lemmon, G. M. Dec. 16, 1919. Direct air-pressure apparatus, automatic.-Relates to a double-chambered apparatus of the kind to which the liquid is supplied by gravity, and from which it is forced by compressed air, the air after the expulsion of the liquid being supplied to the suction end of the compressor. As shown in Fig. 1, the chambers 2, 2a are immersed in the liquid and, preferably, are of small diameter and considerable length. Liquid is supplied by gravity through non-return valves 4, as it rises lifts floats 5, and is ejected through non-return valves 9 to a delivery pipe 8. When either chamber has been discharged its float seats in the conical bottom 6 and prevents the escape of the compressed air. The air-connexions are controlled by a sliding cylindrical valve 11 in a casing 12, Figs. 1 and 2. When this valve is in the position shown in Fig. 2, air under pressure is passing from the compressor 10, through pipes 21, 23 to the vessel 2 and through a pipe 24 to the lefthand end of the valve-casing 12. At the same time the chamber 2a is in communication with the suction end of the compressor through pipes 26, 28, and the right-hand of the casing is exhausted through the pipes 27, 28. When the float 5 has sealed the chamber 2 the air pressure in the pipe 21 rises and opens a valve 44, which presses a locking-bar 40 clear of a projection on the valvespindle 33, allowing the air pressure on the lefthand end of the valve to move it to the right. The movement of the valve 44 vents the air pipe 21 through a port 49 in the valve-casing, so that the spring 48 can close the valve and allow a spring 43 to move the bar 40 to lock the valve in the new position. The air in the chamber 2 now escapes through the pipes 23, 30 and valve-port 20<a> to the suction pipe 28, and at the same time the left-hand end of the valve casing 12 is exhausted through the pipe 24, while air under pressure is supplied to the chamber 2a through the pipe 21, valve-port 20, and the pipes 25, 26, and to the right-hand end of the valve-casing 12 by the pipe 27. When the chamber 2a has been emptied, the pressure in the pipe 21 rises as before and the valve 11 is reversed. Air leakage is replaced through a non-return valve 31a.

Abstract: 160,129. White, A. E., (International De Lavaud Manufacturing Corporation, Ltd.). Dec. 12, 1919. Casting - machines; moulds; clamping and guiding moulds. - A mould for use on a centrifugal casting- machine is formed from a series of thin annuli 31 connected together by tie bolts 39 in such manner as to allow limited lateral flexibility and avoid distortion due to unequal heating. The mould rests upon rollers 32 by which it is driven and which assist in circulating cooling water in a bath 40. A telescopic supply pipe and a drain pipe 44 are provided. A detent ring 35 engages grooves in the rollers to prevent relative axial movement. The rings may be stamped from sheet metal and may be accurately machined before assembly. Rings for smaller moulds may be punched from the central discs thus reducing waste. The water penetrates to some extent between the laminations which also serve to vent the mould The level of the water in the bath is such as to prevent entry of metal to the interior of the mould. In a modificaion a series of laminae 56, Fig. 5, are united by fusion with the aid of added metal for example along grooves 57, to form sections that are afterwards machined and connected by tie bolts, registration between the sections being secured by means such as dowels 62. In the event of the laminae being united com. pletely round their circumference the tie bolts are made a loose fit in their holes to provide for venting.
