IPC: F16F9/34
Filed: 1952-05-28
Abstract: 699,949. Hydraulic dampers. GENERAL MOTORS CORPORATION. May 28, 1952 [June 29, 1951], No. 13485/52. Class 108 (iii] The valve mechanism between the reservoir and one of the working chambers of an hydraulic damper comprises three spring-loaded valves 55, 62, 66, liquid flow in one direction being established by the movement of all three valves as a unit, and in the other direction by three successively and differentially restricted flows, firstly through an orifice 57 in the valve 55, secondly by opening by the valve 66 of an orifice 65 in the valve 62, and thirdly by movement of the valve 62 relative to the valve 55 in which it is supported. The orifice 57 is constantly open, and, as shown, is provided by a notch formed in a liner 56. This liner may, however, be dispensed with. The orifice 57 is then formed by a notch cut in the seating of the valve 55. Movement of the valves as a unit in the upward direction is resisted by resilient fingers 76a integral with a ring 76. The damper piston (Fig. 1, not shown) is formed with inner and outer concentric series of ports controlled by two respective valves at opposite ends of the piston. At least one of the valves may have a constantly open orifice. Specification 661,479 is referred to.

Title: Method and apparatus for examining currency bank notes and tokens of value
IPC: G07D7/182
Filed: 1975-04-02
Abstract: 1509295 Bank note examining PITNEYBOWES Inc 2 April 1975 [2 April 1974] 13541/75 Heading G1A In a bank note or token examining system, light from a lamp 140, Fig. 8, and reflector 142 is passed through a note in an examining station 133 to be received by a photo-transistor 148 mounted in front of a parabolic reflective surface 146. The phototransistor 148's output signal is preamplified and fed to integrating means to integrate the transmissivity of the bill over the whole of the bill. If the integrating value is less than a predetermined value it is deemed to be "fit" (for continued use) and is directed by movable fingers 66a, 66b along a conveyer belt path to a collecting and stacking point 42. A "bill spacer" from a dispenser 58 is added to the stack of bills every hundred bills. If the bill is "unfit" it is directed to another similar collecting point 46 via a demonitizing unit 44 which prints a series of bars, Fig. 10 (not shown), on the notes (to prevent the notes being used). The system also has a series of photo-diodes 166 each within a sleeve 160 and behind a lens 164 designed to detect the presence of the "cancelled" bills with the bar markings, and to stop the machine if such cancelled bills are detected. The system is also designed to detect a very low transmissivity, thereby indicating that two bills are stuck together and to route the "double-bill" back to the operator. The system includes counting devices 77, 48, to count the number of bills passing to each stacking point 42 or 46 and a monitoring device 44, 45, checking that the demonitizing bars are being printed. The description includes extensive operational details of the conveyer belt system and an associated signal logic processing system.

Title: Improved Method of, and Apparatus for the Production of Weft Spools or Cops on Weft Spinning Machines.
Inventor: CHANE MAURICE
IPC: B65H54/14
Filed: 1916-09-28
Abstract: 109,242. Chane, M. Aug. 28, 1916, [Convention date]. Ring and traveller frames; driving-arrangements.-In the production of weft spools or cops on ring-spinning frames, the theoretical twist given to the yarn during the building of the first half or two-thirds of the cop bottom is greater than that given to the yarn during the building of the rest of the cop, in order that the actual twist may be substantially constant throughout the cop to facilitate unwinding in the loom shuttle. The alteration in the twist may be effected by increasing the speed of the gear 5, Fig. 1, through which the rollers are driven at the required stage of the building of the cop. The gear 5 is carried by a box 1 loose on the main shaft 2 and connected through pawl 3 to a ratchet-wheel 4 fast on the shaft 2. The slower drive is through the ratchet and pawls. The gear 5 also engages an equal gear 10 on a shaft 9 carrying a claw clutch 8, 8<1>, the loose part of the clutch being geared to a wheel 6 on the main shaft. When the clutch is closed, the gear 6 drives the box 1 through the shaft 9 at a speed greater than the ratchet 4, causing the pawl to slip over the ratchet teeth. The pawls are weighted to assist the centrifugal force to keep them out of contact with the ratchet teeth at the higher speed. An automatic arrangement to control the clutch 8, 8<1> comprises a lever 13, Fig. 4, held against the action of a spring 16 by a catch 17 and lever 19 until the rising ring-rail 21 engages the lever 19 and releases the catch. The lever 19 is returned by a spring 24 into position against a stop 23. A stop 25 limits the movement of the lever 13. The lever is returned to reopen the clutch 8, 8<1> at the end of the lift by a connexion with the handle which is used to raise the thread-guides.

Title: Improvements in and relating to hydraulic turbines and pumps
IPC: F03B15/00
Filed: 1964-04-03
Abstract: 995,520. Hydraulic turbines and pumps. SULZER BROS. Ltd. April 3, 1964 [April 5, 1963], No. 13890/64. Headings F1C and F1T. In a method of varying the flow through an hydraulic turbine or pump of the type having at least one surge chamber, a variation #Q of the flow is obtained by automatically adjusting the flow control member of the machine, over a period of time amounting to one period of the oscillation of the water level in the surge chamber, in two steps, viz., a first step in which the flow is varied by #Q/2 and, after the first half period, a second step in which the flow is again varied by #Q/2. The invention is described as applied to a storage power plant comprising a reversible hydraulic flow machine which can operate as a turbine or as a pump and is connected to a lower storage basin through a long tunnel, a surge chamber being provided between the tunnel and the machine. The machine is connected to the upper storage basin through a penstock which is connected to another surge chamber. When the machine is to be operated as a pump, a valve in the pump delivery line is opened. If the valve were fully opened, the water level in the intake system would drop far below the cavitation limit and the water level would continue to oscillate for a long time. Instead, the valve is initially opened to give half the full delivery, as shown by the chain-dotted line 1. Because of the inertia of the mass of water in the tunnel, most of the water flow is initially supplied from the surge chamber so that the water level in the surge chamber drops as shown by the sine curve 2. After a quarter of the period of oscillation the water level has reached its lowest point and the direction of flow in the surge chamber reverses and the water level starts to rise, reaching the original level at the end of half a period. If the valve were left at the same setting, the water level would continue to rise in the second half of the oscillation period as shown at 2a. Instead, the valve is now fully opened, thereby theoretically inducing a second oscillation in the surge chamber as shown at 3. The oscillations 2a and 3 cancel out, so that the water level remains steady as shown by the horizontal line 4. The curve 5 shows the flow from the tunnel. The opening of the valve is controlled either by a time-delay relay or by a device sensitive to the water level in the surge chamber.
Patent GB-682862-A (GB)
Title: Production of artificial resins from indole and aldehydes
IPC: C08G12/26
Filed: 1949-05-24
Abstract: Artificial resins are produced from indole and an aldehyde, particularly formaldehyde.  Acid, e.g. sulphuric acid or alkali, e.g. soda lye, can be used as condensation catalyst.  At room temperature chlorsulphonic or hydrochloric acid may be used. Indole-containing coal-tar portions may be employed.  Preferably they are enriched to 10 per cent indole.  Hydrocarbon solvents may be present during the reaction, stirring being then essential if aqueous formaldehyde be used.  The hydrocarbons are preferably those accompanying the indole in the coal-tar fraction. Preferably, the fraction is free from phenols.  In examples: (1) a phenol free tar-oil fraction containing about 20 per cent indole is heated with sulphuric acid and aqueous formaldehyde.  The oily reaction product is vacuum distilled to yield the resin as residue.  Example (2) uses a neutral washing oil fraction containing 5-10 per cent indole.  Example (3) uses a fraction with about 15 per cent indole with glacial acetic acid as catalyst.  Example (4) uses indole dissolved in a -methyl naphthalene with potash lye as a condensation catalyst.

Abstract: 627,019. Electric control systems. PAROLLE ELECTRICAL PLANT CO., Ltd., and ARCHBOLD, E. F. May 9, 1946, No. 14052. [Class 40 (i)] A correspondence control system includes a balanced relay which causes resistance in circuit with one of its coils to be adjusted to restore the balance following variation of another resistance in circuit with its other coil, the latter resistance being on a stationary disc engaged by a wiper arm rotated by a control shaft operated by a device controlled by the relay. As shown, 25 and 4 are the resistances in question, the former being varied as a coke guide trolley 26 moves along a row of ovens 24 while a duplicate apparatus operates similarly for a ram trolley 32 on the other side of the ovens. The operation of the unbalanced relay 28 energizes a coil 20 or 21 controlling one of a pair of ratchets to rotate arms 4, 9 and the relay 31 to enable the coke ram to operate becomes effective only when arms 9 are on aligned contacts which occurs when the two trolleys face the same oven. 2 and 3 are compensating resistances, also adjusted by the ratchets to avoid wide current variations in the circuits of relay coils 28a and b as the trolley resistances are varied. In a modification, the resistance 25, arranged along the row of ovens, is carried by the trolley and is varied as the trolley travels along.
