Title: A Machine for Dyeing Yarn in the Form of Skeins.
Inventor: KILBURN BERTRAM EDWARD DUNBAR
IPC: D06B3/08
Filed: 1916-08-12
Abstract: 105,015. Kilburn, B. E. D., (Sulzer frÞres Soc. Anon.). Aug. 12, 1916. Hank type.-Skeins of yarn are hung in a dye-vat on reels 26, which are reciprocated vertically and at the same time rotated by the engagement of disks 25 on the reels with eccentrics 20, which are rotated first in one direction and then in the other. Each reel is mounted on a vertical bar 41 adapted to be raised for discharge. Rollers 44 between fixed columns 42 serve to guide the reels. A shaft 12, Fig. 1, is clutched alternately to one or other of two oppositely-rotated pulleys mounted on it, by an automatic clutch operated by one of the pulleys. The motion of the shaft 12 is transmitted to intermeshing wheels 21 on the shafts of the eccentrics 20. To raise the reels, a shaft 31, Fig. 1, continuously rotated from one of the pulleys, carries a friction roller 40 rotating in contact with each vertical bar 41, and a loose lever 32 carrying a friction roller 39 rotated by gearing from the shaft 31. The lever 32, normally held in a raised position by a latch 46, is depressed to grip the bar 41 between the rotating friction rollers and to raise the bar and the reel. In a modification, the bar 41, Fig. 5, is formed with a rack engaging a toothed wheel 48 on a lever 32a pivoted at 49 and held in a raised position by a latch 52. To raise the bar, the lever is depressed and the wheel 48 is rotated by engagement with a wheel 51 on a shaft 31. The descent of the bar may be retarded by pressing the wheel 48 against a brake jaw 53.

Title: Improvements in or relating to a process for the extraction of cadium
IPC: C22B17/02
Filed: 1936-04-23
Abstract: 466,534. Precipitating and refining cadmium. BERZELIUS METALLHUTTEN GES. April 23, 1936, No. 11594. Convention date, April 25, 1935. [Class 82 (i)] Cadmium sponge is treated to remove part of the water contained therein and is then melted down in a caustic alkali melt to remove the excess of precipitating metal and impurities such as sulphur, arsenic, antimony, iron, copper, and ceramics. The melting may be effected in an iron crucible 2 heated in a furnace 10, the sponge, in small pieces, being contained in a perforated iron container 1 immersed periodically in the alkali melt 3 by operation of a hand wheel 12. Lead, if present in the raw material, is removed in the manufacture of the sponge by dissolving the raw material in dilute sulphuric acid, clarifying the solution, and precipitating the cadmium by means of refined zinc ; if free of lead, the precipitation may be effected without complete solution of the raw material. Precipitation may be effected in lead tanks 9 lined at 5 with masonry and provided with an agitator 6. Water may be removed from the sponge by pressing or centrifuging. Instead of zinc, aluminium, magnesium or iron may be used as the precipitating metal. The solidified regulus 4 is washed, dried and remelted in paraffin and the alkali melt 3 may be dissolved in water to extract any pellets of cadmium remaining therein and the zinc sulphate, tin, &c. contained therein may be recovered. Any cadmium pellets extracted may be united to form a regulus by further treatment with alkali.

Title: Status system
IPC: G06Q10/02
Filed: 1971-04-27
Abstract: 1344738 Selective signalling VARIAN ASSOCIATES 27 April 1971 [4 May 1970] 11603/71 Heading G4H In a system for monitoring the statuses of a plurality of similar-type objects, the identity and status of one of the objects is signalled, the status being displayed adjacent an indication of the identity of the object, there being means for indicating an inconsistency between the currently reported status of an object and the last reported status of the object. In a room status signalling system for a hotel, room status can be entered on push-buttons at any of a plurality of maid terminals. At a central station, a scan ring scans the maid terminals in turn and when one is reached at which a button has been pushed, the ring stops and the push-button states and the states of dials, used for entering the room number the status relates to, are encoded and transmitted to the central station where they are decoded to control a main status display and a housekeeper's status display. Incompatible successive statuses are recognized by logic to cause a display and print-out of the type of incompatibility and the room number for a clerk who has a control panel from which he can alter the status display like a maid terminal. Counts of numbers of room (e.g. number occupied &c.) are automatically maintained and displayed, at the clerk's panel, and are also subject to count up, count down and reset under the clerk's direct control. Lamps can be lit beside all rooms of a selected type on the main display under manual control to select the type. A cashier's terminal can also affect the status display, having priority over the other terminals for transfer of information. The telephone system may be used for information transfer, using frequency coding. Other applications are mentioned.

Title: Fluid pressure motors
IPC: F01B17/02
Filed: 1946-04-16
Abstract: 623,387. Fluid pressure motors. TRIGGS, W. W. (Gilbert & Barker Manufacturing Co.). April 16, 1946, No. 11627. [Class 122(ii)] [Also in Group XXVIII] A valve 77 is controlled by a valve yoke 81 sliding in its guide 83 and actuated by a rod 82 reciprocating in a hole 108 in the piston rod 10 of a pump for dispensing grease from a container 3 and actuated by a fluid motor which rests on wall of a wheeled cabinet. Toggle links 95 are inter connected with arms 94 of a plate 93 mounted on the cylinder head 44, both links having knife edges 96 and 100 fixed to their ends with a spring 98 between. The inner ends of the toggle links 95 will be raised by the yoke 81 until they cross the horizontal plane in which the fulcrums on arms 94 are located, whereupon the springs 98 will force the yoke rapidly upward to move the valve 77 and to allow recess 78 in the valve to cover passages 59 and 58 in the cylindrical valve seat member 56. A spring 88 encompassing a hub 89 on a pressure plate 87 forces the valve 77 against the valve seat 56. An axial passage 79 in the valve 77 allows pressure fluid to pass from one recess 78 to the other in order to maintain balance of pressure and a hole 90 allows pressure on opposite sides of the plate 87 to be approximately balanced. Pressure fluid enters through a cylinder 31, passage 73, tube 72, passages, (not shown), to passage 58 and through the valve recess 78 into passage 60 and thence by passages 71, 70 and passages, (not shown), into the lower end of cylinder 48, the grease being expelled through the outlet 30 by way of passages 29, 28, 27 and 26.

Title: Improvements in and relating to supply circuits for electric motors
Inventor: KEMP HENRY
IPC: H02P5/50
Filed: 1960-04-01
Abstract: 915,096. Control of several D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 4, 1961 [April 1, 1960], No.11641/60. Class 38 (3). [Also in Group XXXV] A motor M is associated with a grid-controlled rectifier R and inverter I, and, in order to afford smooth transition from motoring to braking with no idling period between the two, a small current is circulated between the rectifier and inverter. A servo amplifier A1 compares the armature voltage of the motor with a reference voltage and supplies an output signal through limiter L1 to current servo-amplifier A2 which also receives a feed-back signal from coil CC. The amplifier A2 supplies a control voltage for the grid control circuit GCR of the rectifier. The inverter is similarly controlled by limiter L2, amplifier A3, and grid control circuit GCI. When the motor is being accelerated, the limiter L1 restricts the input to amplifier A2, the feedback signal from coil CC remaining constant until the motor reaches full speed, whereupon it decreases. When full-speed is approached, the output of amplifier A1 is reduced and the limiter L1 no longer restricts the input to amplifier A2. During the accelerating period and during fullspeed operation, the limiter L2 passes a circulating current reference voltage to amplifier A3, the inverter being controlled to pass a small current. When the motor is being decelerated, the limiter L2 restricts the input to amplifier A3, and the limiter L1 still applies a low current reference to amplifier A2, a circulating current again flowing in the same direction as before. The system is applied to two series-connected motors associated with two series-connected rectifiers and a single inverter. Each motor drives a tachometer generator for controlling the speed relationship of the machines, Fig. 3 (not shown).

Title: Centrifugal amalgamator and method of obtaining metal from ore
IPC: C22B11/10
Filed: 1919-05-09
Abstract: 143,383. Musser, S. G. May 9, 1919. Density separators; mixing-apparatus. - In a centrifugal amalgamator, passages 20, 23, 38 are formed between a fixed shell 19 and a rotating shell 31. The outer shell 26 of the shell 19 is provided with shoulders 24, 25, and the passage 20 is reduced in diameter towards its lower end. The requisite amount of mercury is run into the passage 20, and crushed ore is fed into this passage by a pipe 8. The shell 31 is then rotated, and, during rotation, the mercury forms an annular column in the passage 20 between the shoulders 24, 25, and the ore a downwardly-moving tubular column filling the space in the mercury column. The metal particles of the ore are caused by centrifugal action to occupy the periphery of the ore column, and are thus forced into contact with the inner wall of the mercury column, where amalgamation takes place. The tailings flow through the passage 38 provided with reduced ends 39, Fig. 3, forming nozzles, and are discharged into a helical passage 3 with an outlet 4 in a direction opposite to the direction of the rotation of the shell advocated bv the arrow b. At the lower part 22, Fig. 4, of the passage 20, the wall 26 of the shell 19 is provided with ports 46 fitted with plugs 47 having heads' 48 and provided with threaded sleeves 49 engaging the reduced portions 5) of nipples 51 formed on the wall 26. To remove the amalgam from the passage 20, the machine is stopped, and pipes a are screwed on to the nipples 51 and the plugs 47 removed, the amalgam lowing by the pipes a into a container.

Abstract: 642,276. Builders' hoists. BARTON, C. W. G. April 28, 1948, No. 11677. [Classes 78 (iii) and 78 (v)] In a hoist of the kind comprising four main units, viz. a power-operated winch, a travelling load carrier, a mast on which the load carrier runs and which carries the head gear for the hoisting rope, and a mast platform unit to receive the foot of the mast, the last-mentioned unit has means thereon co-operating with means on the winch unit whereby these units may readily be brought into correct mutual relationship, this relationship being maintained during operation by forces derived from the tension of the hoisting rope. The handles 26, by which the winch unit a is manipulated, are adapted to bear against cut-away parts 43 at the ends of an angle-member 33 of the mast platform unit b, thereby locating these units in correct relationship. The parts are maintained in this position by the hoisting rope 32 which passes from a winding drum 3 on the unit a beneath a sheave 31 on the unit b to a similar sheave at the mast head from whence it passes down and around a sheave 42 on the load carrier unit d to an anchorage at the mast-head. The unit a is provided with a pair of wheels 16 mounted on arms 17 fast on a shaft 18. The forked end 19 of a lever 20 is pivoted at 21 to this shaft, and this lever is normally held in horizontal position by the engagement of a spring-pressed collar 22 with an aperture in a bracket 23. When the collar is released, the lever is swung outwards to clear the member 13 and is then rotated about the axis of the shaft 18 to lower the wheels with respect to the frame. In this position the lever is locked by the engagement of the collar with another fixed bracket (not shown). The shaft 4 of the drum 3 is mounted eccentrically and non- rotatably in bearings 5, each of which is drilled at 14 for the attachment of a weighted operating lever 15. A wheel 9 rigid with the drum is free on the shaft 4 and is engaged also by a brake pad 10 secured to a carrier 11 mounted on a spindle 12 having eccentric parts whereby the clearance between the pad and wheel may be varied. The sheave 13 is mounted in a swivel head 30 pivoted at 37 to a turntable 28 which is mounted in a plate 27 in the unit b. The table 28 is provided with four upstanding pins 29 to engage the lower angle posts 34 of the mast which are arranged as shown in Fig. 2. The load carrier unit d has a pair of flanged wheels 38 which engage the inner faces of the flanges of either adjacent pair of posts. Each wheel is mounted on an arm 39 which projects from the uprights 40 and is adapted to straddle the pair of flanges engaged by the wheels. A pair of rollers 41 mounted on the lower part of the carrier engages the outer faces of the flanges. Pads 45 of compressed fibre are fitted to angle members 46 attached to part of the unit d.
