Title: Wire drawing machine and method
IPC: B21C1/14
Filed: 1961-06-19
Abstract: 908,252. Drawing wire; winding and reeling. VAUGHN MACHINERY CO. June 19, 1961 [March 24, 1960], No. 22113/61. Class 83 (4). A wire handling apparatus comprises a fixed head, a flier assembly journalled in said head, a first take-up block secured to said head, a second take-up block disposed axially adjacent to said first block, wire guide means on said flier assembly arranged to wrap wire around said first block and to unwrap wire from said first block on to said second block, wherefrom the wire convolutions are collected to form a package, and support means for said second block extending through said first block from the fixed head to the second block for orbiting of said wire guide means with respect to said blocks. The column 2 of the machine supports an overhanging head 1 disposed over a well 3 in which is a support structure 4 for pallet 5 on which a package C is formed. The support can be moved by a fluid cylinder 9 from the tilted position shown in Fig. 1 to a horizontal position, for removal of the pallet 5 and package C, and is arranged to rotate slowly to distribute the wire convolutions and form a package of the required shape and size. The wire is guided on to the pallet by rolls 7 and a funnel 63, below the funnel are fingers 65 which hold up the wire while a completed package is removed. The flier assembly 15 comprises a housing 34 and plate 35 mounted on a shaft 17 driven by a motor 26 through a speed reducer 23. Mounted on the plate 35 are three skewed sheaves 36, 37 and 38 and journalled in the housing 34 is a shaft 39 on which are mounted planet wheels 40 and 41. Fastened to the head 1 is block 48 which has a bevelled shoulder 53 and a sun-gear 45, and journalled on the lower end of the shaft 17 by bearings 51 and 52 is a block 47 to which is secured a sun-gear 46. The sun-gears and planet wheels are connected by gear-toothed belts so that as the flier rotates the block 47 is held stationary by the epicyclic action of the gear train. The wire W to be drawn and packaged passes through a bore 29 in the shaft 17, round a sheave 30, over the first skewed sheave 36, through a die 56 and straightening rolls 54 and on to the upper block 48. Due to the bevelled shoulder 53 wire is continuously pushed off the lower end of the block and passes over the sheaves 37 and 38 on to the lower part 47 of the block from which it falls on to the pallet 5. A pair of spring-loaded shoes 61 press on the wire on the lower block in order to build up a single layer of several turns on the block. To maintain the wire tightly round the upper block 48 the lower block 47 may be made of slightly larger diameter or the gearing may be arranged to slowly rotate the block 47 to wrap the wire W thereon at a rate greater than the rate of unwrapping from the part 48.

Title: Improvements in processes and apparatus for treating textile materials in roll form with liquids
IPC: D06B5/00
Filed: 1928-07-31
Abstract: 321,183. Roberts, G. P., and Roberts, G. R. July 31, 1928. Circulating or passing fluids through materials on perforated tubes and drums; piled and pocket materials, treating with fluids. - A number of rolls of textile materials such as yarns or fabrics wound on perforated tubes are carried step by step by a conveyer opposite a series of liquor supply-pipes to which when in position they are automatically coupled. After treatment in these successive positions, during which the rolls may if desired be rotated, a, web of material may be unwound and passed in piled form, on a conveyer vertically oscillated at one end, through a tank. In Fig. 1, cloth 46 is wound on a perforated tube 1 rotated by a contact roller 66. A handle 67 controls screw and nut mechanism by which the roll is lifted on to a pivoted platform 42 down which it rolls into forks 5 on a pair of endless chains 6 which convey it step by step along a guideway 4 into positions successively opposite nozzles 24, 25. During the intermittent motion of the chains, obtained from an intermittently driven shaft 11, the supplies of liquid from a main 35 are cut off by the ends 36 of sliding tubes 28 seating on parts 37 under the action of springs 30. During the treatment, a cam 32 by bell crank levers 31 and collars 29 causes the other ends of the sliding tubes 28 to make fluid-tight clutch-connections with the guide blocks 27 inserted in one end of the perforated tubes 1, and the valves 36 to open. The rolls may simultaneously be rotated by worm gearing at 28<a>. Pistons 62, for blanking off part of an end, may be provided in the tubes 1 to adapt them to fabrics of different width. The trough 41 collecting the percolating liquid, which may be pumped again to the feed-pipes, may be subdivided when the pipes are fed with different dyeing, scouring &c. liquids. On reaching the end of the guideway 4, the rolls pass down a pivoted table 2 to a position 47. Here the fabric is drawn off and passed over a feed roll 49 by which it is fed in loops to an open conveyer-band 50 passing at one end over fixed rolls 52, 53 in a washing bath 51. The roll 54 at the other end of the bath is alternately raised and immersed by a driving crank 55. A similarly moving band 50<a> may be provided above the fabric. The fabric, is finally received on a lifting conveyer band 59, which passes over the roll 54 and a sliding roll 60, and conveyed out of the apparatus. The band 50 may be replaced by a hinged inclined perforated trough with spray pipes above.

Title: Method of and apparatus for packing articles, for example tablets or the like, into containers
IPC: B65B5/10
Filed: 1959-06-29
Abstract: 875,852. Packaging ; applying closures. KRUSE, H., [trading as FETTE, W. [Firm of]]. June 29, 1959 [July 1, 1958], No. 22190/59. Classes 94(1) and 125(2). [Also in Group XXIV] A machine for filling tablets into phials comprises a conveyer and a series of tablet feed points, the conveyer carrying the phials open end downwards over the feed points so that each phial receives one or more tablets at each feed point, passing from one to the next until full, and finally receiving a stopper. The tablets pass from a hopper 22 to a vibratory feeder 26 and on to a shoot 28, a rotary agitator 29 at the end of the shoot directing the tablets into guideways 30. Each guideway leads the tablets to a recess 4 in a plate 1 over which the conveyer, consisting of an intermittently rotating notched wheel 33 and belt 35, or alternatively two opposed belts 15, carries the phials. The tops of the tablets form a continuous surface with the plate 1 and as each phial comes to rest in alignment with the tablets, plungers 9 on a bar 8 rise through apertures in the base of the recesses 4 to place the tablets in the phials. The plungers remain with their working faces level with the surface of the plate and the phials move on. During such movement and once the tablets in the phials are supported by the plate, the plungers 9 descend permitting tablets to enter the recesses 4 from the guideways in time to support the tablets in the phials as the latter again move over them. At the end of the tablet guideways, a shoot 20 delivers plug caps 18 over a plunger 17. A slide 15 supports the tablets and withdraws as the plunger rises with the cap so that the latter supports the tablets as it enters the phial. A rail 19, adjustable as to height to allow for different phial lengths, counters upwards thrust.

Title: Gyroscopic apparatus
IPC: G01C19/26
Filed: 1972-05-12
Abstract: 1436941 Caging mechanism for gyroscopes SPERRY RAND Ltd 14 May 1973 [12 May 1972] 22475/72 Heading G1C Gyroscopic apparatus comprises at least one two-degree-of-freedom gyroscope 1, 2 each having a sensitive element mounted in an inner gimbal rotatable about an axis 4, 5, an outer gimbal mounted about an axis 6, 7 orthogonal to the inner gimbal axis 4, 5 and a caging mechanism 8, for effecting simultaneous caging of the inner and outer gimbals, which comprises a plunger 35 releasably operable to engage a recess 62 on a member 63 on the inner gimbal axis 4, 5. The line of action of the plunger 35 passes through the inner gimbal axis 4, 5 and is parallel to the outer gimbal axis 6, 7 so that no precessional torques are applied to the gyroscope when mechanism 8 is disengaged. The plunger 35 is in the form of a slide mounted in a housing, on springs which are compressed in the caged position, for movement relative thereto, the movement being effected through a cam follower 32 by a cam. In the embodiment described, two gyroscopes 1, 2 are employed, the inner gimbal axes 4, 5 being coaxial, the outer gimbal axes 6, 7 being orthogonal thereby allowing three axis data to be generated. Two caging mechanisms 8 at right angles to each other are then employed, the cams being in the form of parallel connected wheels 19, 24, one wheel 19 comprising a worm wheel driven via a worm gear 18 by a single stepper motor 11. Thus when the gyroscopes 1, 2 are to be caged, they are torqued to within, preferably 1 degree of the caged positions of the gimbals. Mechanism 8 is then actuated by driving motor 11, the wheels 19, 24 rotating so that the respective cam followers 32 begin to follow constant rise portions in cam tracks 25, 26, the plungers 35 moving until they engage the respective recesses 63. Uncaging requires the followers 32 to overcome a step in the cam track, the springs in the plunger 35 then snapping the plungers 35 back to their caged position. A limit switch may be incorporated in the mechanism 8 so as to indicate when the gyroscopes 1, 2 are caged and uncaged.

Title: Process of and apparatus for winding thread on a succession of reels
IPC: B65H67/052
Filed: 1976-06-01
Abstract: 1506192 Continuous thread winding ETUDES ET FABRICATIONS 1 June 1976 [29 May 1975] 22549/76 Heading D1J This invention relates to a thread winding process and apparatus of the kind in which when one take-up reel is fully wound the thread being wound is transferred to an empty reel, the two reels being preferably in parallel side-by-side relationship. According to the invention there is an annulus 1, 2 supporting and rotating with each take-up reel, a single peripheral clamp member 7, 8 on each annulus, fixed anvils 14, 15 one for each annulus to cut the thread when a takeup reel has been filled to capacity, the switching-over of the thread from a filled reel to an empty reel being initiated after the detection of a predetermined angular position of the clamp member fixed on the annulus associated with the empty reel, this angular position being measured with respect to the anvil associated with the empty reel. The switching of the thread may be initiated as soon as the clamp member 8 has reached a predetermined angular position 8a situated down-stream from the anvil 15. A detector 17, Fig. 2, determines when the clamp member 8 has reached position 8a and the thread being wound is then transferred from the full reel to the empty reel so as to be caught by the clamp member 8 before the clamp member 8 again passes the anvil 15, preferably before the clamp member 8 reaches a maximal angular position represented by 8b in Fig. 1. The angle B is preferably about 15 degrees. Immediately after the gripping of the thread by the clamp member 8, the thread is cut by the anvil 15 and the filling of the new reel 9 begins. The detector 17 may be means responsive to a mark, blade or opening 22 rotating with the annulus 2. The detector may be inductive, capacitive, electromagnetic or mechanical.  Similar apparatus is associated with the annulus 1. The invention reduces the risk of the thread coming into an abutting engagement with the free end of the clamp member associated with the next reel to be wound.

Title: Improvements in or relating to apparatus for impressing and cutting dough
IPC: A21C11/10
Filed: 1955-08-06
Abstract: 815,741. Making biscuits &c. VICARS Ltd., T. & T., and GOFF, G. F. C. July 25, 1956, [Aug. 6, 1955], No. 22706/55. Class 87(2). An apparatus for impressing and cutting plastic sheet material, e.g. dough, in which the sheets on a conveyer, is passed successively between an impressing roller and a plain roller and a cutting roller and a plain roller, has the nip of each pair of rollers and the relative register of the impressing and cutting rollers on the sheet adjustable. In an example the sheet, on a conveyer belt 20, is passed between an impressing roller 12 and a plain roller 14 and a cutting roller 13 and a plain roller 19, the plain rollers 14, 19 being frictionally driven by the belt 20 and adjustable in the direction of the impressing and cutting rollers 12, 13 by bearings 14b, 19b slidable in the machine frame 11. The impressing roller 12 is directly driven by a gear wheel 27, meshing with a gear wheel 26 rigidly secured to a main drive shaft 22 which has a further freely rotatable gear wheel 28 and a driving sprocket 21. A countershaft 30 adjustably mounted above the main shaft 22 has two pinions 33a, 33b, keyed together but free to rotate on the cuntershaft. Pinion 33a meshes with the fixed gear wheel 26 and pinion 33b meshes with the freely rotatably gear wheel 28 which transmits its motion through a gear wheel 29 to the cutting roller 13. Movement of the countershaft 30 around the main shaft 22 by means of adjusting bolts 31 causes the pinion 33a to resolve on its own axis and to transmit its motion by the pinion 33b and gear wheels 28, 29, to the cutting roller 13, thus adjusting the relative register on the dough sheet of the impressing and cutting rollers 12, 13. In a modification the gear train is replaced by a chain and sprocket drive, Fig. 3 (not shown), where the adjustment of the relative register of the rollers 12, 13 is effected by the angular displacement of two sprockets about the axis of the roller 13, thus rotating the roller 13 relative to the roller 12. The rollers 14, 19 may be provided with a covering of resilient material.

Abstract: 796,293. Refrigerating. CARRIER ENGINEERING CO., Ltd. Aug. 9, 1955 [Jan. 27, 1955], No. 22975/55. Class 29 [Also in Group XXVI] In a refrigeration system comprising a centrifugal compressor, a condenser and an evaporator, means responsive to the rise in temperature of the gas as it passes through the compressor are provided for maintaining a predetermined volumetric flow of gaseous refrigerant at the inlet to the compressor. In the refrigeration plant shown, the vaporous refrigerant is compressed by a centrifugal compressor driven at constant speed by a motor 11. If the now of vapour from the evaporator 17 falls below that necessary to prevent surging, some of the compressed vapour is returned from the condenser 13 to the compressor inlet through a duct 21 under the control of a valve 22 actuated by a member 23 responsive to the temperature rise in the compressor, sensed by capsules 24, 25. A restriction 33 produces a pressure drop in the duct 21, and liquid refrigerant which passes from the condenser 13 through a pipe 34 to a point downstream of the restriction 33 evaporates as it enters the zone of lower pressure, creating a cooling effect. Thus, the pressure and temeprature of the vapour returned through the duct 21 is lowered to substantially the values at the compressor inlet. A damper 30 at the suction is actuated by a motor 31 in response to the temperature of the chilled water leaving a cooler coil 18, sensed by a capsule 32. Any vapour formed in an economizer 15 is passed through a duct 40 to an interstage point in the compressor. Float valves 14, 15<1> are provided.
