Patent GB-998332-A (GB)
Title: Improvements in electrical induction apparatus
IPC: C22C38/02
Filed: 1962-04-03
Abstract: The grain-oriented silicon steel laminations of the magnetic core of a transformer or dynamo have insulating coatings consisting essentially of beta calcium orthosilicate bonded to the surfaces of those parts only of the laminations in which the magnetic flux travels across the grain.  A coating of magnesium silicate may be bonded to the surfaces of those parts in which the flux travels along the grain.  The coating of beta calcium orthosilicate is formed by coating silicon steel sheets with a water slurry of calcium hydroxide and heating from about 900-1250 DEG C. for 2-8 hours.  The coating is said to decrease the core loss and the magnetostriction.  Two exemplary methods are described, details being given of the cross-grain magnetic properties of the lamination strips prepared thereby.

Title: Improved thread tensioning arrangements in winding machines
IPC: B65H59/38
Filed: 1939-04-29
Abstract: 524,490. Winding thread. UNITED STATES RUBBER CO. April 29, 1939, No. 12880. Convention date, May 12, 1938. [Class 120 (ii)] In a machine for winding thread from a supply by a power-driven take-up package the thread is pulled from the supply and delivered to the take up package at a substantially uniform tension by a snubbing drum around which the thread is looped for substantially a complete circle, the drum being driven at a surface speed in excess of the winding speed of the thread so that the tension in the thread controls the speed at which it is pulled from the supply by the snubbing drum. As shown an elastic thread T passes from a swift 39 to a booster pulley 42 around which it passes before being looped around the snubbing drum 43 by which it is delivered to the traversing guide 34 of the winding head 11. The thread-engaging portions of the pulley 42 and drum 43 are smooth and highly polished and have a surface speed of 10 or 20 times that of the travel of the thread and the drum is tapered to facilitate the spacing of the coil of thread looped around it. The pulley and drum are secured to shafts in a bracket 46 and the shafts carry discs 50, 53 engaging the periphery of a friction driving disc 54 driven by a belt from the shaft 19 ; the bracket 46 is supported for slight rocking movement on a pin 47 so that the discs 50, 53 may engage the disc 54 with substantially the same pressure. The bracket supporting pin 47 is -mounted in a housing 57 pivoted in a yoke bracket 59 and by grasping a hook 61 at the upper end of the housing the latter may be swung outwards to stop the rotation of the drum and pulley, a spring 62 normally urging the drum and pulley into driving positions; the housing is held in its outward position by a spring latch 64 engaging the bottom wall of the housing and the latch is disengaged from the housing to allow the spring 62 to move the housing so that the pulley and drum are driven, by depressing it with the foot. The shaft 19 is driven from a motor 20 and drives the winding spindle 12 by a belt 16 passing through a guide 17 and the traverse cam 28 is driven by a belt 26 from the spindle 12. The thread guide 34 and associated parts are mounted in a housing 30 pivotally mounted on the traverse cam shaft 27, a roller 32 rotatably mounted in the housing resting against the thread package and serving to smooth the coils and lead the thread downwards to the underside of the package. The winding head 11 is mounted on a pivot 35 and is normally held in the winding position by a lever 36 engaging a latch 38 on the head but when it is desired to stop winding the lever 31 is depressed so that the pulley 15 on the winding spindle is lowered and the'belt 16 slackened to stop the drive to the spindle 12. A slub catcher 44 is arranged between the pulley 42 and drum 43.
Patent GB-782162-A (GB)
Title: Electrostatic image developing apparatus and method
IPC: G03G15/08
Filed: 1954-05-04
Abstract: 782,162. Developing electrostatic images. HALOID CO. May 4, 1954 [May 7, 1953], No. 12908/54. Drawings to Specification. Class 98(2) To develop an electrostatic image on .a support with a charged gas suspension of powder, a gas suspension of fine powder is forced through tube so as to create turbulence whereby the particles become charged by frictional contact with the tube while simultaneously the formation of particle aggregates is avoided. In one form of apparatus, gas under pressure, e.g. air, carbon dioxide, fluoro-chloro-alkanes, passes frcm a reservoir into a powder container and the resulting dispersion passes through a capillary tube to be directed closely parallel to the electrostatic imagebearing plate which is supported face down in a grounded tray. In an alternative arrangement the gas, which is compressed by a pump and from which periodic pressure variations have not been completely eliminated issues in a flat jet and passes through a powder-impregnated ribbon mounted between a supply bobbin and a hand- or power-driven take up bobbin, the mouth of a capillary tube being close behind the ribbon. If desired the capilliary tube may pass into an enlarged tube having apertures whereby additional air is mixed with the suspension by a venturi effect, the suspension being directed perpendicularly against a margin of the plate. In a modification, the ribbon is backed by a number of tubes of different shape but of the same length directing the suspension across the plate from separated points along one margin. Preferably the capillary tube diameter is less than 0.050", typically 0.016-0.023", while the length of the tube may be from 0.1" for tubes of less than 0.01" diameter, and typically 4". The gas pressure may be from 10-50 lbs. per square inch, preferably 30-40 lbs. per square inch, while the particle size is not more than 1/10th of the tube diameter and is preferably 1Á. For developing for "direct positive" reproductions positively charged images, the particles are dark, e.g. carbon particles, and are charged negatively by using an earthed metal capillary tube, while for negative or "reversal" reproduction the particles which are deposited on the uncharged areas are positively charged by using a capillary tube of plastic suitably chosen with regard to the triboelectric series. If, as is less common, a negatively charged image is employed light-coloured positively charged particles, e.g. of dyed or pigmented powdered resins, are used to develope the image to a "reversal" picture. Apparatus suitable for use with particles charged to either polarity is one having two sets of capillary tubes, one set of earthed metal and the other set of plastic with means to open and close the sets as desired.

Title: A draught controlling or regulating devices
IPC: F24F13/10
Filed: 1931-05-01
Abstract: 369,050. Draught regulators. LEYS, P. C., 178, ChaussÚe d'Alsemberg, Brussels. May 1, 1931, No. 12917. Convention date, Oct. 22, 1930. [Class 51 (i).] A draught regulating device for chimneys and the like comprises a pair of double oscillation dampers 1, 2 mounted on a common axis and dividing the interior of a casing communicating with the chimney into compartments, two of which 22, 24 communicate by way of openings 26 with the atmosphere whilst the other two 23, 25 communicate with the chimney or flue by way of openings 27. In their normal position the dampers are approximately horizontal and vertical respectively and abut against flanges such as 20 within the casing to form a substantially airtightjoint. The damper 1 is supported by knife edges 3 attached to angle-pieces 8 and working in grooves 4 formed in supports 5 attached to the walls of the casing. The damper 2 comprises two members each having a flange 2<000> and a curved portion 2<00> secured to rings carrying knife edges 14. In operation, if the pressure in the chimney falls below a predetermined level, the dampers rotate and allow atmospheric air from the compartments 22, 24 to travel through the openings 27 into the chimney. The openings 27 are provided with perforated members 29 having perfotations of varying diameters and each damper is provided with an adjustably mounted counterbalance weight 11 by.which may be determined the minimum flue pressure for which the dampers will operate.

Title: Improvements in or relating to power operated hoists
Inventor: BURROWS ARTHUR THOMAS CHARLES
IPC: B66D3/26
Filed: 1949-05-16
Abstract: 668,639. Winding and paying-out apparatus. KING, Ltd., G. W. May 5, 1950. [May 16, 1949] No. 12999/49. Class 78 (v). In a hoist consisting of a load chain passed over a driven sprocket, of the kind having pivoted chain guards movable into and out of operative position, means are provided whereby movement of one of the chain guards from its operative position imparts rotational movement to a shaft which in turn controls the driving motor of the sprocket, whereby movement of the guard cuts off the drive to the sprocket. The load chain 11 is operated by the sprocket 10 which is driven from a motor which is controlled by rotation of a shaft 20 through a suitable switch mechanism. Chain guards 12 are pivoted one at either side of the sprocket and normally held adjacent the sprocket by means of a spring. To each of the guards is pivotally connected a slotted plate 13 or 14 respectively, the slots 15 and 16 thereof having at their adjacent ends enlargements 17, 18 respectively. Each slotted plate is slidable on a boss secured on the shaft 20 and provided with cams 21, 22, fixed in the planes of the plates 13, 14 respectively. One face of each cam is in line with the corresponding face of the other cam as shown. When these faces are horizontal the plates 13, 14 can slide freely. This corresponds to the "off" position of the switch controlling the driving motor. In operation, shaft 20 is turned by a lever 23 operated by hand to place one of the cams in the corresponding enlargement in the plate 13 or 14, corresponding to either forward or reverse drive. Upon engagement of a stop member 24 on the chain with the chain guard at the side of the chain being raised, the appropriate cam is forced out of the enlargement in the plate, turning shaft 20 to its initial "off" position. By means of a link 26 and lever 25 a brake may be operated simultaneously with the opening of the switch. The apparatus also functions to stop the drive when the chain jumps off the sprocket since this also displaces the guards. Specification 557,040 is referred to.

Title: Improvements in method and apparatus for treating films
IPC: G03C5/26
Filed: 1920-05-11
Abstract: 143,230. Mason, J. March 14,1919, [Convention date]. Coating materials in long lengths.- In order to coat one side of a film band and prevent the liquid having access to the other side, the film 6 is drawn by a sprocket 15 from a spool 13 over the surface of the liquid and supported in its passage by ledges or a series of supports 5 which are substantially on a level with the surface of the liquid. The surface tension of the liquid prevents it from flowing through the sprocket or other holes of the film or over the edges of the film. The method and apparatus is particularly adapted for developing or otherwise treating photographic double-coated films, both sides of which may be successively treated with different solutions by reversing the film through 180 degrees between successive baths. This also obviates the necessity for re-winding the films between successive treatments. Intermediate washing baths may be similarly used.

Abstract: 409,509. Sheet-delivery apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Shellmar Products Co. ; 3501, West 48th Place, Chicago, U.S.A.) May 4, 1933, No. 13062. [Class 100 (i).] Apparatus for delivering paper sheets, particularly from a printing and cutting machine, comprises hook-members 18 into the open ends of which the sheets are fed so as to be carried by the hooks over a pile table where stops 24 strip the sheets from the members 18. The sheets cut from a printed web by knives 54, 58 are received by tapes 70, 72 travelling at a higher speed than the web. A plate 82 supports the horizontal run of the tapes 70. Endless chains 12 moving slightly slower than the tapes 70, 72, and carrying the hookmembers 18, overlap the forward end of the tapes 70 so that the sheets are supported by the tape 5 at their rear ends when the forward ends are engaged in the hook members 18. The tapes 72 extend beyond the tapes 70 and co-operate with the members 18 to grip the sheets sufficiently to carry them over the pile table where stop 24 strips them from the members 18 so that they drop on to the table. For dealing with different-length sheets, the drive of the chains 12 is disconnected and the necessary adjustment of the position of the members 18 relatively to the knives, when a sheet is being cut, is made. The tapes 70, 72 and chains 12 are carried by a frame 112 adjustable laterally on the main frame 114 by a handwheel 118 and bevel-gearing so as to be situated centrally widthwise of the sheets. The pile table may consist of an endless-band 32 moving slowly in a transverse direction so that the sheets are delivered in overlapping formation. A pile-table 170, Fig. 5, may be employed and is carried by pinions 172 running on racks 174 and operated by bevel-gearing 178, 180 and ratchet-mechanism 186 actuated from a driven shaft 96. Where the band-delivery 32 is employed, the stops 24 are carried by a lever 140 controlled by a rotating snail cam 144 so that the sheets are delivered in staggered relationship to separate them into counted batches. Rotating members 160 may be provided to move the sheets downwardly on to the pile when released from the members 18.
