Patent GB-111210-A (GB)
Title: An Improved Interleaving and Folding Machines of the Two-cylinder Type.
Inventor: BROWN HORACE PERCIVAL
IPC: B65H45/24
Filed: 1917-02-06
Abstract: 111,210. Brown, H. P., and Johnston, C. L. Feb. 6, 1917. Folding paper.- Sheets of paper for towels, toilet papers, &c. are cut from two webs and interfolded by a pair of co-operating inter-folding cylinders, from which thev are delivered in zigzag fashion by aid of stripping and controlling devices to endless carrierbands. One edge of each sheet is preferably folded to strengthen it, this fold coinciding with the fold at the middle of the next interleaved sheet. A mark may be made at intervals on the folded edge of a section, so that the delivered sections may be divided into batches of predetermined number for packing, &c. Fig. 4 shows a sectional view through the pair of cylinders 10, 11 to each of which a web 15 is fed, as shown, and is cut into sheets by blades 18 on revolving arms 19 cooperating with cutting-slots 20 on the cylinders 10, 11. In rear of each slot 20 is a set of impaling- pins 24 and a folding-blade 13. On the cylinders, midway between the two sets of pins 24 and blades 13, are folding-grippers 12 which nip the folds of the sheets as they are tucked into them by the blades 13 of the opposite cylinder. Near each gripper 12 is a set of impaling-pins 14 which operate to transfer the folded papers from one cylinder to the other so that they are delivered alternately from the cylinders in zigzag form as shown. The grippers 12 and pins 24, 14 are operated by cams so as to engage and release the paper at the required times. As the web of paper is cut by the blades 18 it is held by a rubber gripping-block 21 in front of each blade. In the rear of each blade IS is a spring-pressed block 22 which forces the severed end of the web down forward of the folding-blade 13 while the pins 24 pierce it. As the cuts are made forward of the blades 13, a sheet near its forward edge from one cylinder and the middle line of the next sheet from the other cylinder, are folded together into the grippers 12, as shown. The sheets are stripped from the cylinders by rocking fingers 44 entering grooves in the cylinders and acting to transfer the alternate folded edges to intermittently rotating tumblers 47 having longitudinal ribs or teeth which engage the folded edges and direct them on to the delivery bands 52, 67, 70. A mark is made as at x on the edge of a fold at the required intervals by a marking-block on a cylinder geared to the cylinder 11, the web 15 being passed round the marking cylinder as it is fed to the cylinder 11, and the marking block being timed by the driving-gear to co-operate with an opposed platen at every 25th revolution or as required.
Patent GB-766503-A (GB)
Title: Improvements in or relating to inflating device for tubeless tires
IPC: B60C25/14
Filed: 1955-01-21
Abstract: 766,503. Pneumatic tyres. FIRESTONE TIRE & RUBBER CO. Jan. 21, 1955 [Jan. 9, 1954], No. 1879/55. Classes 144 (1) and 144 (2). A tubeless tyre mounting device for facilitating inflation of the tyre 44 and correct seating of the tyre beads on the wheel rim bead seats comprises a closure means 27 to bridge and seal the opening between a wheel rim flange and the adjacent side of a tubeless tyre being mounted on the rim, the closure means 27 comprising an axially collapsible and expansible cylindrical body 27a having a thin, flexible, air-impervious convoluted wall, of for example, reinforced rubber, rendered radially inextensible by inextensible rings 32, 33, encircling the body within its convolutes. The body is sealed at one end 70 to a flange 71 of a rigid cylinder 37 and at its other end 36 terminates in an inextensibly beaded thin edge 31, 51 to seal against a tyre side wall. Alternatively the beaded end 36 may have a cellular rubber-like ring attached thereto which will permit a slow leakage of air. The cylinder 37 has a radially inwardly-extending flange 38 carrying a rubber ring 40 to seal against the edge of a wheel rim flange 41, and is integrally connected by spokes 4 with a hub 5 by which it can be bolted on a support frame 10 to overlie a ram 46. In operation, a wheel with a tubeless tyre loosely mounted thereon, as shown in Fig. 4, is mounted on a ram which is then operated to raise the wheel until the rim flange 41 and tyre side wall seal against the ring 40 and the body edge 51 respectively. Inflation of the tyre may then be effected either through the inflation valve 43 on the wheel rim or through an opening 90 in the rigid cylinder 37 of the closure means. In the former case, build-up of pressure within the tyre will cause the tyre bead 49 to engage and eventually snap on to its rim seat, and in the latter case removal of the air supply, thereby allowing sudden exhaust through the opening 90 will effect the correct seating of tyre bead 49. The closure means may be used as a bead-breaker by pressurizing it through the opening 90 to exert pressure on the outside of the bead of a deflated tyre. In alternative arrangements, the wheel and tyre assembly may be mounted on a support column and the closure means clamped thereover, or closure means 27 may be applied to both sides of an assembly which is supported with its axis horizontal. A portable closure means may comprise a rigid dished plate which can be bolted coaxially to a wheel so that the sealing ring 40 and expandable body 27a operatively engage the wheel rim and tyre.

Title: Improvements in color screen control
IPC: F21V17/02
Filed: 1932-01-22
Abstract: 385,761. Lantern screens. KLIEGL, J. H., 321, West 50th Street, New York, U.S.A. Jan. 22, 1932, No. 1971. [Class 75 (iv).] Colour screens for use with spot lights are moved into their operative positions by a control mechanism comprising magnetic control apparatus, which, when energized, moves the screen against the action of a spring. The action is such that the initial moving force is considerably greater than the maximum resistance encountered, and the screen is thereafter moved to its operative position by a smaller force. A series of screens 14 is mounted each on a concentric shaft 18, 20, 22, 24, and normally held in inoperative position by torque springs 42 and counterweights 28. The plungers 32 of four solenoids 30 are connected by links 34 to crank arms 36, one on each concentric shaft. The circuit is shown diagrammatically in Fig. 6. Each shaft carries a non- conducting collar 46 with conducting sections 50 out of contact with each other. When it is desired to move a screen into its operative position, the corresponding contact 54 is closed by depressing a key 52. The greater part of the current from a source 56 passes through a conductor 58, solenoid 30, spring blade 66, section 50, blade 68, and conductor 70, a smaller part passing through a conductor 60 and resistance 62. The solenoid plunger moves and begins to rotate its appropriate shaft, whentherotation has proceeded sufficiently for the section 50 to be in contact with one only of the spring blades, the loop 70 is cut out and, owing to the resistance 62, a reduced current passes through the solenoid. The effect is that the movement of the screen is started vigorously and continued gently. Padded rods to act as buffers for the screens are disposed at the limits of their movement.

Title: Improvements relating to the treatment of solid carbonaceous material, chiefly designed for the production of fuel gases
IPC: C10B49/22
Filed: 1944-02-04
Abstract: 586,391. Distilling and gasifying solid carbonaceous materials. ARNOLD, C. (Standard Oil Development Co.). Feb. 4, 1944, No. 2116. [Class 55 (i)] A process for obtaining fuel gas from coal, coke; peat, shale, tar sands &c. in so called fluidized suspension, i.e., dispersed pulverulent form in a fluid stream, comprises passing the stream through at least two chambers in which combustion and carbonization or gasification are respectively effected, heat for the second chamber being carried from the first by continuous streams of the fluidized solid. In apparatus including both carbonization and water gas generation chambers, finely ground coal dropping from a crusher 1 is dispersed in superheated steam introduced by a pipe 3 and carried into a carbonization chamber 5, solid products being blown thence through a pipe 8 into a combustion chamber 9 by air admitted through a pipe 10, and distillates passed through a cooler 13 and apparatus for recovery of tar, light oils, ammonia and fuel gas. A continuous stream of material from the combustion chamber returns to chamber 5 through a pipe 11 and another is discharged through a pipe 11<1> into a generator 18 which is also supplied with superheated steam through a pipe 19. Combustion products from chamber 9 pass to a dust separator 15 and cooler and waste heat boiler 16 and the water gas after treatment in a dust separator 21 and cooler 22 may be mixed with some or all of the distillation gases..Temperatures in chambers 5, 9, 18 may be 500-1200‹F, 1800-2400‹F., and 1400-2000‹F. respectively. The gasification step may be cut out by means of a valve in pipe 11<1> or coke as the raw material may be fed directly into pipe 8 and the carbonization chamber cut out. Some of the water gas generated may be treated catalytic.ally with steam and the carbon dioxide removed, the hydrogen being employed to hydrogenate the liquid distillation products from the original carbonization. Inert material such as sand may be added to the coal or accumulating ash serve as additional heat carrier; lime, magnesia &c. may be included to raise the ash melting point.

Title: Improvements in the method of, and apparatus for, winding yarn
IPC: B65H54/16
Filed: 1929-01-22
Abstract: 323,133. Hoffmann, A., and B÷rner, A. Jan. 22, 1929. Winding - machines; spindle - driving arrangements. -In a machine for winding yarn on coned bobbins the thread-guide is reciprocated parallel with the bobbin and is given a gain movement of the thread-guide due to the growth of the bobbin, the guide being maintained out of contact with the wound thread and its movement being caused by deflection of the yarn travelling from the guide to the bobbin. The traverse is such that the bobbin is closely wound when the thread-guide is ascending while the descending turns are widely spaced. The bobbin a, Fig. 1, is mounted on a spindle t driven by friction wheels b, b<1>, a chain d and sprocket wheel d<1>, driving a parallel spindle g the upper end g' of which is screwthreaded while the lower end has right- and lefthanded screw-threads h, h<1>, Fig. 4, to provide respectively the close and open windings. The thread-guide m is supported in a forked member n having a collar r and provided with a flat nut i engaging the threads g<1>. A braking bolt o is slidably mounted in the support n and is connected to a double-armed lever v carrying a thread-feeler v<1> and rotatable about a pin g. When winding on the smallest diameter of the bobbin the lever v is as shown in Fig. 3, and moves to the position shown in Fig. 5 when winding on the full diameter, the lever v then pressing the bolt o against and arresting the nut i, the support a moving upwardly on the threaded part g<1> until the nut i is released. The constant traverse is effected by the engagement of a - spring-pressed feeler w in the threads h, h<1>. When winding on the larger diameters the disc b<1> is braked by a block 2 actuated through a pin 6 on a lever 10 and through levers 5, 3 by the engagement of a knob g<11> on the spindle g' with a curved bar 8 depending from the free end of the lever 10.

Title: Improvements in the manufacture of nickel iron alloys
IPC: C22C1/04
Filed: 1930-01-22
Abstract: In the manufacture of alloy powders containing iron and nickel, suitable for the cores of loading coils, electromagnets and the like, by the reduction of the mixed oxides of the metals in a stream of gas, the reduced powder is sintered at a higher temperature than that of reduction.  Preferably the powder is washed in water or dilute acid before sintering.  The sintered material is pulverized and annealed, if necessary a fine refractory powder being mixed with it to prevent sintering.  In one method of procedure suitable weights of the oxides, mixed together in the dry condition, or in a colloid mill followed by filtration and drying, are reduced by hydrogen at 850 DEG C.  The pulverized reduced product is washed with a 5 per cent solution of hydrochloric acid at 50 DEG  C. followed by cold water and dried.  It is then sintered at 1000 DEG  C. in a reducing atmosphere for about 1 hour, cooled, ball-milled, mixed with about 2,5 per cent of talc powder, and annealed.  In the case of a nickel-iron alloy containing 80 per cent of nickel the annealing temperature is 900 DEG  C.  A suitable insulating coating is applied to the powder by heating it in a solution of chromic anhydride and a halogen acid or last to dryness after which it is formed into cores by pressing and annealing.  Specification 338,321, [Class 35, Dynamo-electric generators &c.], is referred to.

Title: Improvements in loud speakers and the like
IPC: H04R9/04
Filed: 1928-01-25
Abstract: 310,441. Lucas, 0. D. Jan. 25, 1928. Loud - speakers; diaphragms; magnetic instruments.- Sound-reproducing apparatus of the moving coil type has the coil and attached diaphragm suspended by one or more silk or like loops from an adjustable suspension. Each loop is provided with means whereby the suspension can be adjusted both vertically and laterally. In the construction shown in Figs. 1 and 2, a cone 2 carrying a coi] 20 has its outer periphery secured to an annulus 6 of rubber batiste &c. clamped between cardboard &c. washers by rings 31, 32. The ring 32 is carried on radial inclined arms 33, 34, 35 extending from a flange 36 which is secured to a flange 37 on a cylinder 38 carried by a standard 40 and secured to the cylinder 39 of the pot magnet. The inner end of the cone is supported by a silk &c. thread 41 having its ends' secured to a pin 42 as shown. The central portion 42a of the pin 42 is screwed horizontally in a vertically adjustable screw 43 carried by a plate 44 which is secured by a pin 45 to the flange 37. Back lash on the adjusting screws is prevented by providing the screw 43 with an extension 43<a> surrounded by a spring 43<b> and by mounting the screw' 42 in spring jaws 46<a> on a U-shaped plate 46 secured to the plate 44. The cone is preferably made of blotting or other soft paper covered internally with thin smooth paper and strengthened externally by radially arranged ribs of paper &c. In the modification, Fig. 3, the cone 2 is supported at its smaller and larger ends by adjustable loops 9, 8, the loop 8 being considerably longer than loop 9. The periphery 2b of the cone is attached to a bellows-like structure comprising an annulus 3 of sateen, rubbered silk, &c., the outer edge of which is attached to one edge of an annulus 4, the other edge of which is in turn mounted in a circular hole in a square piece of fabric 5 attached to a rigid frame 7. An exponential horn 2 is fitted to the frame 7. The movement of the cone 2 and coil 20 may be damped by superimposing a certain amount of steady current on the audio-frequency current passing through the coil. This may be done in the case of the transformer coupled system shown in Fig. 3 by bye-passing from the primary 21 to the secondary 22 of transformer 2, through a high variable resistance 23, a small percentage of the current from the high tension battery 24. Similarly, with the choke-capacity system shown in Fig. 4, a small amount of the high tension current from battery 24 is bye-passed through a variable resistance 23 placed across the coupling condenser 26. Alternatively, a steady current supplied through a controlling resistance 25, either from the high or low tension sources, may be passed through a secondary winding 30 of a smaller number of turns arranged on top of the winding 20. The Provisional Specification states that the free ends of the diaphragm supporting loop may be attached at a common point to any adjustable suspension.
