Title: Improvements in and relating to apparatus for indicating rate of acceleration and retardation
IPC: G01P15/08
Filed: 1935-04-26
Abstract: 455,861. Electric signalling systems. NEW, C. E., 20, Bucklersbury, Wallbrook, and ROSE, S. A. M., 111, Gray's Inn Road, both in London. April 26, 1935, No. 12579. [Class 40 (i)] Apparatus for the direct indication of the rate of change, acceleration or retardation in the physical variables pressure, speed and temperature comprises a moving member actuated directly or indirectly by the physical variable which operates an electrical generator the current from which is measured by an electrical instrument to show the rate of change of the variable and whether it is rising or falling. Fig. 1 shows the invention applied to the measurement of rate of change of pressure. The pressure acts on a piston 1 adapted to move against the influence of springs 3. The piston rod 5 is connected through a multiplying gear 6, 6, 6 on the last shaft of which is mounted an armature 7 rotating in a magnetic field 8 and supplying current to a moving coil instrument 9. When the pressure is steady the instrument reads zero, but when the piston is moving the instrument reads to one side or the other of zero according as to whether the pressure is rising or falling. In a modification, the rod 5 is connected to the core of a solenoid connected in circuit with the indicating instrument. In a second modification, the final spindle of the gear 6, 6, 6 rotates a magnet near a copper disc carrying a pointer and adapted to rotate about the axis of the final shaft against the influence of a hair spring which maintains the pointer at zero when the variable is steady. In a further form adapted to measure variations of speed, the needle of the speedometer has mounted upon its spindle an armature rotating in a magnetic field and connected to an electrical instrument indicating acceleration or retardation. Visible or audible signals as shown in Fig. 6 may be combined with the above devices. A disc 34 driven by the gear 6, 6, 6 has on its circumference cams 36 which actuate an impulse current transmitter 37. A friction change-over switch 38 is mounted on the spindle 35 and is adapted to rock between two contacts 39, 40 thus closing circuit 41 or 42 and causing lamps 43 and 44 of different colour to light up or gongs 45, 46 of different tone to be sounded. A light sensitive cell 47 may be substituted for the impulse transmitter 37, one or more apertures 48 being provided in the disc to come between a lamp and the cell. The impulses originated by the movement of the disc 34 may be used to energize solenoids and through ratchet gear to move a valve controlling for instance the fuel supply to a boiler.

Title: Improvements in and relating to motor vehicles
IPC: F16H61/56
Filed: 1936-05-05
Abstract: 454,914. Controlling motor vehicles ; hydraulic transmission. SOC. ANON. A. SAURER, Arbon, Switzerland. May 5, 1936, No. 12672. Convention date, May 21, 1935. [Class 79 (v)] [See also Group XXIX] A hand-operated lever 1 controls the fuel supply of the engine from idle running to a maximum during one part AB of its range, and controls the vanes of a hydro-dynamic transmission gear driving the road wheels during the remainder BC of its range. In the construction shown the lever 1 operates a sliding rod 7 having a collar 8 abutted, in the mid position shown of the lever, by bellcranks 11, 12, controlled by springs 17, 18 and connected respectively to the fuel pump 23 of a Diesel engine and the pivoted vanes 27 of an hydraulic transformer. Adjustable stops 19, 20 limit the movements of the bellcranks. In the position shown the fuel supply, or the throttle opening, is at a maximum, and the vanes 27 are fully open. If the lever 1 is moved in the range BC, the collar 8 moves away from the bell-crank 11, leaving the fuel supply at its maximum, and rotates the bellcrank 12 and the vanes 27 to reduce the cross-sectional area through the vanes thereby increasing the vehicle speed. When the lever 1 is moved from the mid position in the range BA the collar 8 moves away from the bell-crank 12, leaving the vanes fully open, and rotates the bell-crank 11 to reduce the fuel supply to the idle running condition of the engine.

Title: Improvements in Vehicle Suspensions
Inventor: MOULTON ALEXANDER ERIC
IPC: B60G11/62
Filed: 1967-03-17
Abstract: 1,192,082. Vehicle suspensions. MOULTON DEVELOPMENTS Ltd. 17 June, 1968 [17 March, 1967], No. 12706/67. Heading B7D. A wheel suspension system in which a diaphragm type displacer unit is individually associated with the wheel, is characterized in that the displacer unit housing 1 is carried in a casing 4 which is pivotally mounted on a journal shaft 5, which in turn is fixed to the sprung structure 8 through flexible mounting bush 9, the piston 2 of the displacer unit being connected to the wheel 13 through a linkage 6, 12 so arranged that wheel movements, due to road surface inequalities, on being transmitted to the displacer unit, tend to cause pivotal movement of the casing 4 about the journal shaft 5, the pivotal movement being absorbed by a flexible mounting 15 arranged between the sprung structure 8 and either the casing 4, or the displacer unit housing 1 or some other element rigidly associated with the casing or housing. As shown the piston 2 bears, through a piston strut 2a and a ball-and-socket joint 10, on an arm 6, the free end of which bears on a wheel supporting member 12 e.g. a "king post" through a ball-and-socket joint 11. Vertical movements of the wheel will transmit force to the piston 2 through the arm 6 and strut 2a, and also to the journal shaft 5, in which ease the flexible mountings 9 will absorb the thrust. The movement communicated to the piston 2 will cause fluid to be displaced to or from chamber 14 and will also produce thrusts which tend to cause the casing to pivot about journal 5, such forces being absorbed by flexible mountings 15 between the casing and the sprung structure 8. In a modification for trailing arm suspensions, Figs. 3 and 4 (not shown) the trailing arm is pivotally mounted on a journal shaft, and is provided adjacent the mounting with a short, upwardly extending crank abutment, which acts on the displacer piston through a piston strut and a ball-and-socket joint.

Title: Improvements in the manufacture of felt
IPC: D04H1/74
Filed: 1943-08-09
Abstract: 568,950. Felt making. WHITEHEAD & BROS., Ltd., R. R., and PORRITT, C. P. Aug. 9, 1943, No. 12799. [Class 42 (ii)] A batt of felt is formed by feeding a continuous web of fibre upon a conveyer, moving parallel with the fibres, the speed of feed being greater than the speed of the conveyer, the web of fibre being formed into a plurality of layers 39 which are then compressed to form the batt of felt. The machine is driven by an electric motor &c. through a master variable speed gear 1A which turns the shaft 12 and hence the shaft 2 of a variable speed gear-box which drives the doffer 7 to take the web of fibres from the swift 1 and lead it to the conveyer 8, 9 which passes it to downwardly moving belts 14, 15, the lower ends of which are mounted on a reciprocating carriage 16. The drive for the carriage is taken from variable speed gears 43, 49 through reduction gears and pulleys, with open and crossed belts 47, 48, driving fast pulleys on the shaft 24 which turns the sprocket 18 which, through a chain 17, operates the carriage. The belts 47, 48 are shifted by means of a fork moved by stops 31, 32 on a rod 30 upon contact of the carriage 16 therewith. Beneath the carriage is a conveyer 33 driven by chains 56, 57 from a reduction unit 54 driven by a variable speed gear 55 from the shaft 34, the speed of the conveyer 33 being less than the speed of the feed belts 14, 15. By reason of the reciprocation of the carriage 16 and the movement of the conveyer 33, the web of fibres is laid as at 39, Fig. 2. The folded batt is compressed by rolls 36, 37 and delivered at 38. A covering web may be overlaid thereon, such web being folded to and fro across the batt as at 40, Fig. 3.

Title: Improvements in or relating to loading chutes
IPC: B65D90/58
Filed: 1936-05-06
Abstract: 464,883. Shoots. NYBORG, T. G., and MINING ENGINEERING CO., Ltd. May 6, 1936, No. 12804. [Class 78 (i)] In shoots providec with a closing door operated by the moving material, a member is provided which lies be low or substantially ir line with the bottom of the shoot when in the idle position and can be moved up into the line of flow of the material to be operated thereby to - close the door. Swinging the handle 9 clockwise, rotates the crank 10 about the pivot 6 and lifts the link 11, thus turning the pivoted flap 7 to a position at right-angles to the flow of the material. The flap is pivoted at 8 to the door 4 and when the impact of the material moves the raised flap bodily, it causes the main door to close by swinging clockwise about the pivot 6. When the flap is turned back parallel to the flow of the material, the door re-opens partly by gravity and partly by pressure of the material. The operating handle during the latter part of each movement abuts against stops on the door and thus can be used to give positive assistance in the opening and closing.

Filed: 1975-03-27
Abstract: 1502822 Applying tapes to packages VEREENIGDE METAALVERPAKKING EN HECHTDRAAD INDUSTRIE BV MVM-ENDRA 27 March 1975 13046/75 Heading B8C A method of applying a tape around an object or stack of objects 10, Fig. 1, comprises passing a tape, consisting of two tapes 9 emanating from supply reels 6 and having their ends interconnected, about the stack 10 in U-shaped fashion; forcing towards one another the portions of the tapes extending between the supply reels and the stack; clamping each said tape portion at a given distance from the other tape portion at two places spaced apart by about twice said given distance in a direction normal to the stack; cutting one said tape portion midway between its clamping places; directing the tape ends thus formed towards the other tape portion; cutting the other tape portion midway between its clamping places; bending the thus formed tape ends against the first tape ends and joining them thereto; and releasing the clamped portions, so that the stack is surrounded by a closed tape, and a tape extends again between the supply reels. As described, a stack of objects 10 on a pallet 3 is pushed against tapes 9 extending between four pairs of supply reels 6. Once the position shown in Fig. 1 is reached tape strainers 8, Fig. 3, are advanced to force the tape portions together, and a stop member 13 carried by one strainer 8 is pivoted by a fixed cam 15 to a position between the ends of the two strainers 8 so that when the strainers are fully advanced the tape portions 9, Fig. 4, are clamped between clamping faces 17, and 20, on the strainers 8 and faces 22, 23, respectively, on the member 13. A piston 27 in one strainer 8 is then advanced to cause a knife 28 to sever one tape portion 9 and then to cause a member 25 to advance to bend the severed tape ends against faces 24 of the member 13, before the knife advances into a groove 31 to sever the other tape portion. A piston 29 then advances a member 30 which folds the second pair of severed tape ends against the first pair on the surfaces 24 and also forces back the member 25 which causes glue to pass from a cavity 33 via passages 32 on to the tape ends to secure them together in pairs. Heat may also be applied, or instead of glueing, welding or fusing may be effected. The member 30 is then retracted, and the strainers 8 withdrawn to leave a taped stack and a tape extending again between the supply reels 6.

Title: Improvements in and relating to Multi-Stage Pump Units and Pump Turbine Units of Radial Flow Construction in Pumped Storage Power Stations
Inventor: WALLER HEINZ
IPC: F03B13/06
Filed: 1967-03-21
Abstract: 1,184,824. Starting centrifugal pumps. SULZER BROS. Ltd. March 21, 1967 [March 24, 1966], No.13120/67. Heading F1C. A multi-stage pump or pump-turbine of radial flow type with fixed impeller blades in a pumped storage power plant includes means for admitting compressed air to the machine to drive out water, and at least one opening upstream of the first impeller relative to the direction of flow to the inlet of the machine for the release of air from the machine, the opening leading to flow control means including a throttle for controlling flow through the opening. Water is driven out of the machine shown in Fig. 3, prior to starting it as a pump, by admitting compressed air from a line 21 via a shut-off valve 23, a pipe 20, an annular manifold 19 and openings 18. The machine is then accelerated by an auxiliary machine to the synchronous speed of the main electrical machine, which is already connected to the mains. The valve 23 is then closed and a shut-off valve 25 is opened to allow the compressed air to escape via the openings 18, the pipe 20 and a line 22. The rate of escape is controlled by an adjustable throttling diaphragm 24 so that the rate of increase of power consumption as the air is replaced by water does not exceed 5% of the full output per second, whereby a sudden large increase of power consumption is avoided. It is found that the compressed air escapes not continuously but in surges, apparently due to the openings 18 being temporarily at least partially closed by the water flowing into the machine from the inlet line 17. When the machine has been filled with water, a shut-off valve 15 in the delivery line is opened and pumping commences. The time taken to fill the machine can be reduced by opening a shut-off valve 27 at the same time as the valve 25 so that water from a line 26 can also flow into the machine downstream of the first impeller 4 under the control of an adjustable throttling diaphragm 31. The valves 23, 25, 27 and 15 may be controlled automatically in accordance with a predetermined programme, and the automatic control means may receive an input signal from a device sensitive to the speed of the shaft 1 or to synchronization of the main electrical machine. The pump or pump-turbine may be of double-entry type and may have a vertical shaft. The manifold 19 and openings 18 may be located upstream of the inlet volute 29.
