Title: Improved means for winding paper or other webs into rolls
IPC: B65H18/16
Filed: 1926-06-30
Abstract: 278,084. Marks, E. C. R., (Cameron Machine Co.). June 30, 1926. Winding webs.- In a web-winding apparatus, particularly for winding paper as it is delivered from a paper-making machine, means is provided whereby the winding-shaft is caused, owing to the accumulation of material upon it, to travel over the surface of the winding-drum into a delivery position in which it is out of contact with the drum. Means may be provided for automatically feeding a new winding-shaft into engagement with the winding-means. In one form, Fig. 1, the ends of the winding-shaft 2 are mounted in guides 3 having hinged portions 4 to allow of the insertion of the shaft and the guides are so shaped that the roll during winding travels over the surface of the winding-drum 1. When the shaft reaches the upper ends of the guides 3. it enters open bearings 8 in a pair of arms 6 mounted on pivots 7 and is retained therein by weighted latches 9 pivoted on the :arms 6. As the material continues to accumulate on the shaft 2, the arms 6 move about their pivots and carry the roll over the surface of the drum until the arms 6 pass the vertical position when they fall over into contact with a stop 15 and deliver the roll on to a support 13. During this movement the latches 9 are released by contact with fixed cams 14. After the web is severed and attached to a new winding-shaft previously placed in the guides 3, and the full roll removed, the arms 6 are returned to normal position by hand or by the action of weights 12. In a modification, Fig. 3, spare winding-shafts are mounted in a magazine 17 and held by a detent 18 on a shaft 19 carrying an arm 20 coacting with a pin 22 on one of the arms 6, When the arms have moved sufficiently to take the pin 22 clear of the arm 20, the detent 18 falls and allows a winding-shaft to engage the drum 1. Specifications 276,778 and 278,083 are referred to,

The condensers and rectifiers are arranged in a Liebenow-Greinacher circuit, the output terminal 15 of which is connected to the output socket 25 of the power pack through a pair of damping resistors 18 which, in association with a mains-operated earthing switch 26, 27, also serve to discharge the condensers when the pack is switched off. The tank, which may be provided with a cooling pipe 28, may also contain auxiliary transformers, such as 22. The tubular condensers are of rectangular crosssection.

[Also in Divisions D1, E1 and H1] A metallic felt for use as a filter comprises staple metal fibres having a fracture free, unmachined and unburnished outer surface and a mean transverse diameter of less than 50 microns held by frictional engagement of the said surfaces. The pore sizes of the layers of a laminated filter may decrease progressively in the direction of fluid flow. Metal rods are supported in a matrix of e.g. monel metal to form a billet which is drawn till the filaments attain the required diameter. The fibres are then cut preferably while supported in the matrix or tensilely broken after removal of the matrix. The fibres, in the range ¢ to 6 inches, may be crimped. The fibres are then picked and carded, and after possible laminating and annealing are compacted or creped.

Title: Improvements relating to electrical regulating arrangements
IPC: G05F1/32
Filed: 1947-06-26
Abstract: 637,664. Automatic regulation. HARMER, H, M. June 26,1947, No. 16884. [Class 38 (iv)] In a regulating device comprising a saturated and an unsaturated inductance in series across an A.C. source, the load voltage is stabilized against variations in source frequency by the provision, in parallel with the saturable inductance, of an impedance, the value of which varies as the supply frequency. As shown in Figs. 1 and 2, the regulating arrangements described in Specifications 493,362 and 524,565 are modified by the connection of a series LCR circuit across part of the saturable reactor 2. The series circuit is tuned to resonate at the lowest supply frequency and changes in the supply frequency are accompanied by changes in the relative phases of the voltage vectors at the impedances 1, 2 and the source Vs which counteracts the tendency of the load voltage at 3 to rise due to the increase in the rate of change of flux in 1 and 2. Specifications 515,207, 522,314, [Group XIX], and 554,467 also are referred to.

Abstract: 816,932. Escapement mechanism. GLEASON WORKS. May 28, 1957 [June 29, 1956], No. 16952/57. Class 80 (1). [Also in Groups XXII, XXIII and XXXVIII]  A machine for forming and testing clutch and other toothed parts comprises a power-operated indexing means for intermittently rotating a work-spindle 22, on a support movable between a forming and a testing position and means operable by the index drive for moving a bracket carrying a pair of gauges to engage them with a tooth of the workpiece when in the testing position, (see Group XXII). A motor 27, Fig. 3, through change gears 29, drives an index-drive shaft 36. Once every two revolutions of the shaft 36, a cam 53 rocks a lever 50 to engage a slotted disc 47 with a roller 46 on a disc 45. The roller 46 at first enters a slot 48<SP>1</SP>, Fig. 4, and quickly accelerates the disc 47. As it leaves the slot, a gear segment 51 engages. a gear 52 and the disc 47 is rotated at a constant speed until the segment disengages from the gear and the roller enters a second slot 48<SP>11</SP> to decelerate the disc 47 to a stop, at which time the cam 53 withdraws the disc from the roller. The movement of the disc 47 is transmitted to the work through index change gears 58 and a worm 59. The index gearing is locked by a plunger (not shown) engaging a disc 61 and operated by a cam 62.

In an electrostatic powder sprayer in which the powder drops from a trough-like receptacle 4, Fig. 6 through an elatrostatic field established between two parallel pivotally mounted discharge tubes 80,81 the powder discharge is metered by making the bottom of the receptacle in the form of a rotating roller 11 contacted tangentially by a flexible steel sealing strip 43 and a flexible steel wiping blade 23. The strip and the blade may each be laterally deformed by screws 22 so that they become relatively rigid and substantially straight in a longitudinal direction.

An apparatus for orientating tapered tubes 7 comprises two horizontal parallel spaced endless belts 6, on to which the horizontally positioned tubes 7 which lay longitudinal of the belts, are delivered from a shoot 5, the space between the belts 6 being equal to the diameter of the tubes 7 at about a third their length from the large diameter end, whereupon the thinner end of each tube 7 gravitates through the space and the tubes become vertical. The horizontal randomly spaced tubes 7 are fed to the shoot 5 by endless horizontal belts 1, 2 and an inclined belt 3 having laths 4, the speed of each successive belt being greater than the previous to effect spacing of the tubes. At the downstream end of the spaced belts 6, a further endless belt passes around the downstream pulley of the belts 6 and between the belts 6 whereby each tube 7 is conveyed out of the space and into a horizontal position on the further belt from which it is diverted further downstream by an inclined plate.

Glass is conditioned in a furnace which has two vertical columns 2, 11 which as shown are concentric and which must be in good heattransfer relationship and are connected at the top by a chamber 13 in which a reduced pressure is established by pumps 17, 21, the glass being heated during displacement up the column 2. The heating of the furnace is arranged so that the hottest part of each column is at the top and thus the glass descending the inner column 11 (the conditioning column) is heated by the ascending stream in the outer column 2. Raw materials are added at 25 and finished glass drawn off at 29. The difference in level in these two tanks enables the apparatus to function as a siphon. A probe 32 operates, on contact with the glass, a servo-mechanism 33 which controls a valve 38 to connect the cooling unit 19 for pump 17 to the air. In a modification (not shown) the glass rises in an inner column and is conditioned in the outer column and glass is drawn upwardly from both sides of the draw-off tank to form sheet glass in conventional manner.
