Title: Improvements in and relating to electric regulating apparatus
IPC: H02P9/20
Filed: 1930-09-06
Abstract: 355,532. Automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Thompson, L. W. ; 53, Baker Avenue, Schenectady, New York, U.S.A.) Sept. 6, 1930, No. 26680. Convention date, Sept. 6, 1929. [Classes 35 and 38 (iv).] Exciting.-A carbon-pile rheostat is automatically operated by a fluid-pressure actuated piston controlled by a pilot valve subject to electro-expansive means for effecting regulation. A cam actuated by the piston operates link mechanism connected to the pilot valve and to the electro-responsive means to restore the valve to a desired position and prevent hunting. Means are provided to maintain the pressure on the carbon pile if the fluid pressure falls below a given value. The regulating range of the carbon pile rheostat may be adjusted by a variable resistance in parallel therewith. Fig. 1 shows a system for a three-phase generator 1 in which a dynamo-electric device 24 such as is described in Specification 296,402, [Class 38 (iv), Electric supply and transmission systems &c.], operates through link mechanism a pilot valve 19 controlling the position of a piston 12 and cam 52. The piston varies the compression on a carbon-pile rheostat 8 in shunt with a resistance 9 in the field circuit of the alternator and the cam 52 operates through a roller 57 and spring- controlled element to restore the pilot valve to closed positions whatever be the direction of movement of the piston. A dashpot device 42 damps the action of the device 24 but permits rapid initial movement. An excess current coil 39 modifies the operation when a given current is exceeded. A pawl 56 is placed in engagement with a rack 58 to maintain the pressure on the carbon pile when the fluid pressure in an expansion loop 54 falls below a given value. A generator operating a three-wire d.c. system is shown in Fig. 2 and the carbon-pile rheostat 73 is in series with an adjustable resistance 72 across the outers. The field winding 69 of a motor 67 giving a back electromotive force in the shunt field circuit of the generator 60 is in parallel with the rheostat 73. The motor has a constant field 70. The strength of the field 69 is varied in accordance with the resistance of the carbon pile 73 and the generator field correspondingly varied in an inverse sense by fluid-pressure means similar to those in the arrangement just described but controlled by a coil 92 responsive to the voltage across the outers and an under compounding coil 95 to facilitate parallel running. Coils 99, 104 responsive to the currents in positive and negative sides of the system effect a decrease in the excitation of the generator on excessive current on either side of the system. The antihunting means comprises a dashpot 111 controlled by the cam 112 attached to the piston 75, and coupled to the pilot valve 80 through springs 109.

Title: Improvements in time measuring apparatus with a synchronous motor and an auxiliary movement for the driving of time controlled apparatus, such as clocks and time switches
IPC: G04C23/06
Filed: 1936-10-02
Abstract: 461,548. Electric clocks. LANDIS & GYR AKT.-GES. Oct. 2, 1936, No. 26805. Convention date, Oct. 5, 1935. [Class 139] In a clock, time switch or other time-controlled apparatus, driven by synchronous motor and provided with an auxiliary spring driven movement for taking over the drive when the current fails, a secondary escapement is provided between the auxiliary main spring and the time-controlled apparatus whereby when the auxiliary spring is operative the clock &c. is advanced intermittently at fairly long intervals permitting a comparatively small auxiliary mainspring to be used. The synchronous motor 4 normally drives a twenty-four dial 21 of a time switch &c. through gearing 2, 3, a double ratchet or overrunning device 1 and gearing 20, and winds the auxiliary spring in barrel 10 in known manner. When the current fails, the auxiliary spring barrel 10 drives the dial 21 through gearing 9, 8, 7, the ratchet 1 and gearing 20 under the control of a secondary escapement 5. The escapement 5 comprises a detent or escaping member 11 rigid with shaft 71 and a releasing member 19 notched at 17, 18 and driven by a maintaining spring 14 through gearing 12, 13, 15 under the control of the usual escapement 16, which, in known manner, is normally locked and released automatically when the current supply fails. When the releasing member 19 reaches the position shown, the detent 11 passes through the notch 18 and the dial 21 is advanced rapidly by the auxiliary spring 10 until the other arm of detent 11 abuts against the releasing member 19 where it is held until released by notch 17. The spring 14 is rewound at each advance of the detent 11, overwinding being prevented by a frictional connection between spring 14 and the gear-wheel 12. The intermittent advance of the dial 21 in this way permits a comparatively small spring 10 to be used where the power required is fairly large.

Abstract: 1,037,459. Assembling barrels. WILLIAM GRANT & SONS Ltd. June 9, 1965 [June 30, 1964]. No. 26941/64. Heading B8D. Casks are assembled in apparatus comprising a cradle 4 which is vertically adjustable and rotatable, end plates 3 movable inwards on rails 2 by means of ram mechanism 7, and a clamping band 10, 13, Fig. 4 (not shown), the lower half 10 of which is placed in the cradle 4 before the staves forming the lower part of the cask are placed in position within the cradle. The end plates 3 carry curved ledges 11, on which the staves of the upper part of the cask are supported, and guides 12 for holding the intermediate staves in position. The part 13 of the clamping band is then applied and engaged at its ends, with the part 10 of the band. Overlapping portions of the part 13 of the band are tightened by means of a device 18. The rams 7 withdraw the end plates 3, and the cradle 4 is rotated through 90 degrees by means of a turn-table 6. Cables 19, Fig. 2 (not shown), are looped round the ends of the staves and tightened by means of rams 21 to draw the stave ends together and allow truss hoops to be applied. The cables 19 are then slackened and the cradle returned to its initial position, where the plates 3 are used to press the hoops further on to the cask by means of members 22, Fig. 5 (not shown), carried by the plates 3. The part 13 of the clamp is unfastened, the plates 3 are withdrawn, and the cask is again turned through 90 degrees, enabling it to be removed to further apparatus (not shown) comprising steaming heads for softening and swelling the wood. The croze is machine cut at each end of the cask, head pieces are fitted, the truss hoops are removed, and normal hoops are fitted in their place. The upper part of the clamp may be suspended by means of a cable from pulleys supported above the apparatus, the opposite end of the cable carrying a counterweight 28 (see drawing with Complete Specification). The clamp may be tightened by hydraulic means 30-32.

Title: Means for cutting off measured lengths of materials
IPC: B23D33/00
Filed: 1963-07-09
Abstract: 1,020,994. Shearing. L.S. WALLIS. June 5, 1964 [July 9, 1963], No. 27066/63. Heading B3W. Apparatus for cutting off measured lengths of material comprises power-driven feeding means connected to feed drive rolls through a variablethrow crank and adapted to feed material under the control of a counter or equivalent device which, when a pre-set length of material has been fed, stops the feed means and starts a power-operated cut-off means to sever the length. The apparatus comprises a crankshaft, driven by a pulley 16 to which is attached a calibrated variable-throw crank 11 having a rack bar 12 which via a one-way key clutch drives the lower of a pair of feed rolls 14, 15. A pawl 22, Fig. 4 (not shown), having a throwout cam portion 25 is pivoted to a boss 23 and spring biased into engagement with a notch 21 in the circumference of a hardened ring 16a mounted inside the pulley 16. De-energization of a solenoid 27, Fig. 2 (not shown), releases a spring-biased pin 26 which withdraws the pawl from the notch and disengages the clutch. The guillotine comprises a blade 28 eccentrically driven via a one-revolution clutch the actuation pin of which is controlled by a spring-loaded rocker controlled by a solenoid 34, Fig. 3 (not shown). In operation a switch is operated to energize the solenoid 27 which retracts the pin 26 and engages the clutch 17 to drive the feed rollers. A counter 37 actuated by a cam 35 via a leaf spring 36 at each revolution of the crankshaft, operates a switch which breaks the circuit to disengage the feed clutch when the desired length of material has been fed and energizes the solenoid 34 to operate the guillotine. A finger 40 on the guillotine slide operates a mechanism 39 to reset the counter and operate the switch for a further cycle. A limit switch operated by the guillotine ensures that it is stationary before further feeding occurs. The guillotine and feed means are driven by a constantly rotating flywheel.

Title: Improvements in switching mechanisms for automatic telephone systems and the like
IPC: H01H67/12
Filed: 1925-10-29
Abstract: 264,268. Siemens Bros. & Co., Ltd., and Caswell, A. E. Oct. 29, 1925. Automatic exchange systems and selectors.-A selector comprises a number of notched discs or cylinders 7 - - 9 which are rotated by numerical or hunting impulses, and a number of pivoted bars 3 which are normally held out of engagement with the discs by a cam 21. When the discs have been set the cam is rotated and the bar that finds notches for all its projections 4 - - 6 falls, bringing the end of a pivoted member 16 opposite an insulating member on a spring 18. Further rotation of the cam forces a group of contact members such as 17 against the wires of the wanted line. The member 19 may be supported by one of the contact springs as shown in Fig. 5 and the arrangement is preferably such that the spring in the test circuit makes contact first. When the selector is used as a group selector the cylinders 7, 8 are set by numerical impulses and the normal position of the cylinder 9 is such that when cam 21 is rotated the first line of the group is engaged. If it is busy the cam takes a full rotation and pauses while the disc is given a step whereupon the second line is tested and so on. With the above selector the multiple wires are arranged in one plane. In a modification, Fig. 6 they are arranged in breadth and depth. The selector comprises a thousand units like that shown in the figure, a particular one being selected as before by the combined setting of cylinders 41 - - 43. Rotation of cam 45 brings a rack 31 carrying wipers 36, 37, and one or more further wipers on its opposite face into engagement with a pinion 46 on the same shaft as the cam and which is rotated by numerical or hunting impulses. At the end of the call the cam is rotated to normal and the wiper rack is restored by the weight 39 acting on the flexible cable by which connection is made to the wipers. One or more of the notched cylinders may be omitted. The selectors may be used in systems in which the selectors are controlled by forward or reverting impulses or in which they hunt for terminals marked by a register. In cases where there are two or more cam cylinders, two or more digits may be received simultaneously since no switching takes place until all the cylinders have been set. The numbering of the lines may be altered by altering the positions of the cylinders instead of the connections to the multiple. The selector shown in Fig. 6 is of special utility where it is necessary in response to three digits to select a line to a distant office. In this case there would only be as many units in the selector as there are offices. According to the Provisional Specification, the bars 3 are mounted on knife edges and the cam 21 may be shaped like a ratchet wheel so that connection with the multiple may be effected in two or more stages. A switch like that shown in Fig. 6 may be used for hunting through large groups by making the arrival of the first set of wipers on its final terminals start up the second set and so on.

Abstract: 1395620 Dyeing textiles CARRINGTON VIYELLA Ltd 5 June 1973 [12 June 1972] 27300/72 Heading D1L In a dyeing process which comprises passing the material through a dye bath wherein the amount of dye liquor absorbed is in excess of the amount the material can hold and introducing the dyed material into a heated curing chamber wherein the excess of liquor is shed and collected in a reservoir, controlling the composition of the used dyestuff liquor by withdrawing dye liquor from the reservoir at the same rate as it collects, subjecting samples of this withdrawn liquor to spectrographic analysis in a comparative analysis unit, directing the remainder of the liquor withdrawn to a make-up apparatus controlled by the analysis unit wherein the dye liquor is reconstituted according to signals from the analysis unit, mixed with additional fresh new liquor, and returned to the dye bath. The material dyed may be blankets, felts, heavy textiles and carpets in continuous lengths. As shown in the flow diagram carpet 3 is dyed in bath 1 and introduced into steaming chamber 2 from which excess liquor via a manifold system 13 is collected in tank 4 after passing through filter 14, from where after passing through another filter unit 16 the liquor flows into cooler 5 controlled thermostatically and then into an averaging tank 6 fitted with a mixer 26 and liquid level control device 27. From this tank via regulator valve 32 the liquor flows through a sampling point 7, and a flow meter 8 to make-up apparatus 9. The sample of dye liquor withdrawn at 7 is subjected to spectrographic analysis in unit 10 and compared with that of a fresh dye liquor sample. Resulting signals from the unit are fed to apparatus 9 where dye components from tanks 35 and 36 are injected by metering pumps 37 and 38 into an injection manifold 39 to mix with flowing liquor in pipe 33. Before mixing with fresh dye liquor the composition of the made-up liquor is further tested in cell 34, and if unsuitable is discarded via valves 40 and 41.

Title: Improvements in or relating to bearings
IPC: F16C19/12
Filed: 1934-09-25
Abstract: 431,544. Universal joints. AKTIEBOLAGET NOMY, Ulvsunda, Stockholm. Sept. 25, 1934, No. 27497. Convention date, Sept. 29, 1933. [Class 80 (ii)] [See also Groups XXXIV, XXV, and XXXV] In a gas or air lubricated bearing having relatively rotatable sliding surfaces 17, 17a of sufficiently large diameter to ensure the formation of the necessary air film, parallelism of the surfaces under all conditions is ensured by universally supporting at least one of these surfaces by cardan-like members having a high-rigidity in the radial direction to withstand radial loads. The spinning spindle 11, Fig. 1, carries a hollow pulley 16 the inside of which is spaced from a non-rotatable sleeve 22 universally mounted with respect to a stationary sleeve 18 by the air pressure generated solely by the rotation of the pulley. Similar air-lubricated bearing surfaces 17a are provided at the bottom of the spindle but in this case, the universally mounted sleeve 22a is rotatable with a sleeve 13 on the spindle. The cardan devices, Fig. 2, for the sleeves 22, 22a comprise an integral or laminated resilient ring 20 engaged by flanged pins 19, 21 engaging the sleeves 18, 22 respectively. A modified form of cardan device comprises a series of thin annular discs 30, Fig. 7, with projections 31, 32 spaced 90‹ apart which are clamped between rings 33 ..36, Fig. 6, held in place by screwed or force fitted rings 37, 38. The ring 38 has a projection 38a to limit the tilting of the sleeve 22. Projections on the outer and inner clamping rings 34, 35 extending more than half the thickness of the rings prevent their relative circumferential movement. A single disc 30 may however be used. The surfaces 17, 17a are formed of moisture-resisting material such as nickel or chromium steel, or the artificial resin known under the Registered Trade Mark " Bakelite," or the cellulose product known under the Registered Trade Mark " Cellon." The whirl of air between the conical parts 16b, 25b prevents the entry of dust &c. into the bearing. In a modified form of spinning spindle fitted with the universal mountings shown in Figs. 6 and 7, the sleeve 18 is integral with the bracket 25 which is secured to the housing 23 through an intermediate sleeve, and the pulley 16 is made in two parts.

Abstract: 809,872. Haymaking machines. GOODALL, C., and GOODALL, M. Sept. 4, 1957 [Sept. 10, 1956], No. 27573/56. Class 6(3). Relates to a machine, such as a rake-wheel type of hay-rake, wherein a frame carries one or more tined rotary tools each suspended by a pivoted arm on the frame. According to the invention the tool is balanced by a combination of a weight and a spring so that in one limit position of the arm the counterbalancing depends wholly on the spring and in the other, the weight only is operative. As shown, the rake-wheel 6 is suspended from the frame 5 by a crank 8 pivoted at 10, the outer end of the arm carrying a standard 13 to which is attached a spring 14, the rear ends of all the springs being anchored to a rod 15 movable longitudinally on the frame. The crank 8 is integral with an arm 11 carrying a weight 12 which is normally vertically above the pivot 10 so that counter balancing is effected by the spring ; when the crank 8 rises to its upper limit, the spring becomes slack and counterbalancing is effected by the weight 12. A cable or chain may extend parallel to the spring to prevent overstretching and a stop 16 contacts the arm 11 to prevent excessive downward movement of the rakewheel. The arrangement may be used upsidedown so that the functions of spring and weight are reversed.
