Filed: 1974-05-21
Abstract: 1466883 Hooke's joints NADELLA and A PITNER 21 May 1974 [25 May 1973] 22619/74 Heading F2U [Also in Division B3] A method of forming a bearing surface 13 on a central portion of the end face 12 of at least one of the trunnions 1 of a metal universal joint cross member 2, the surface being formed at a desired distance b from a reference point 0 in the cross-member, comprises performing a pressing operation by a tool 21 on a cross-member blank having a central end portion at a distance a from the reference point, thereby cold upsetting the central end portion to form the bearing surface at the desired distance from the reference point. The trunnion 1 is capped by a coldformed sheet metal cup 3 enclosing needles 4 and a resilient washer 16 which includes a planar part 17 bearing against an annular ridge 18 on the cup. The planar part may alternatively be dished, Figs. 2, 3 (not shown), when it is of smaller diameter than the cup opening defined by a flange 9. The bearing surface may be formed by a convex end surface (53) of a spigot (55),-Figs. 5, 6 (not shown), and lubricating grooves (59) are formed in the surface (53). The press tools 21 are, in this case, provided with concave or hollowed out centre portions to shape the spigots (55) and the distance a is consequently less than the final distance b.

Abstract: 378,643. Recovering waste rubber. RUBBER REGENERATING CO., Naugatuck, Connecticut, U.S.A.-(Assignees of Bull, A. W. ; 253, Paulin Boulevard, Leonia, New Jersey, U.S.A.) Aug. 11, 1931, No. 22710. Convention date, Aug. 22, 1930. [Class 70.] A process for separating the rubber and fabric contents of waste materials such as tyres, comprises disintegrating the material in a dry state, removing loose rubber, diluting the remainder with liquid, beating and separating the rubber freed thereby, thickening the mass and further treating to separate the rubber and reduce the fabric to fibres. Material is cracked in a mill 1, and passes to a screen 2 through which the loose rubber is carried to a digester 4, while the fabric with adhering rubber is fed to a bin 6 and thence to a beater 7 where it is mixed with water, preferably water which has been used before and still contains some fibres. The beaten pulp passes to a storage tank 8 and thence to a dilution box 9 where more water is added. From here the pulp passes through a screen 11, for removing rubber particles which are conveyed to the digester 4, while the fibres pass to a thickener 14 where the bulk of the water is removed by a pump 10 and returned to the dilution box 9. The thickened pulp is fed to a second beater 18, and after treatment is again diluted in a box 21 fed with water from a pipe 22 and passed through a screen 24, which separates the rubber and passes it over another screen 25 to the digester 4, while the pulp is fed to a centrifuge 27 for removing more rubber. The pulp is then agitated with oils in a vessel 28 and again centrifuged, the rubber as before passing to the digester 4. The clean fibre is felted in a machine 30 and the water is removed by a pump 31 and is returned by a pipe line 22 for re-use in the process.

Abstract: 852,061. Automatic gramophones. HANSEN, H. C. Aug. 13, 1956 [Aug. 8, 1955], No. 22817/55. Class 40 (2). In a record-changing gramophone in which vertical and horizontal movements of the tonearm 14 are controlled by sets of tracks on a single-rotation cam disc 60, substantially as in Specification 788,053, an arm 74, carrying a cam-track follower 76 frictionally drives a spindle 15 carrying the pick-up, whose movements are limited by abutments. Fig. 4 is the playing state, where the follower 76 is free to move in the region 80 and the cam disc 60 is held stationary in a predetermined position. Entry of the stylus into the record cut-off groove engages a lever 70 with a lever 72 to actuate a trip-starter and the cam disc 60 rotates clockwise. Engagement of a wall 88 with the follower 76, in conjunction with the friction drive to the spindle 15 and a limiting abutment swings the pick-up clear of the turntable. As the follower 76 follows the track 92, the pick-up tends to swing inwardly again but is prevented from so doing by an abutment 40 engaging the edge of the lowermost of the stacked records awaiting play, if any and the follower 76 is accordingly directed along either a " stop " track 96 or a " gauge " track 98 by which gauging, feeding and playing are controlled, a track selector plate 100 in the Fig. 7 position steering the follower 76 past the entrance to track 96. The " stop " track swings the pick-up clear of the turntable where it is lowered on to a switch 24 (Fig. 1, not shown) forming a pick-up rest, which stops the machine. Specifications 757,303, 801,174, 852,062, 852,064 and 852,065 also are referred to.

Title: Improvements in or relating to the production of ink
IPC: B43L25/08
Filed: 1923-09-11
Abstract: 225,933. Goldsmith, B. B. Sept. 11, 1923. Ink; inkstands.-Ink is produced by passing a solvent, such as water, through passages in a cartridge formed of or containing ink-producing material. The cartridge may be composed entirely of solid ink-producing material, or of a neutral body coated with the material, or pieces of the material may be inserted in the passages. The cartridge may comprise a solid body having the passages formed therein, Figs. 1 and 5, or an assemblage of bodies spaced apart by separate or integral means, Figs. 8 and 15, and the passages may be so arranged that the solvent flows from the exterior into an interior space, which serves as a dipping-well. When the ink consists of a soluble colour and gum, or of constituents which unite to form a soluble ink, the constituents can be dissolved and the neutral body coated with the solution, or a paste can be made and pressed into shape. In the case of insoluble ink, such as iron-tannin inks which contain an iron salt, tannic acid or the like, a dye, gum, a substance to prevent precipitation, and a preservative, the materials are made into a paste with binding- medium, e.g. alcohol, in which not more than one of the reacting-substances is soluble, but which itself is soluble in the liquid added to produce the liquid ink. In another method, the reacting-ingredients are kept separate and different parts of the cartridge are coated with different ingredients. An inkstand for use with the cartridge is shown in Fig. 20, and comprises a reservoir 67 for the solvent detachably connected to a dipping-well 68 by a neck in which a removable cartridge 69 is placed.

Abstract: 1330045 Fluorescent discharge lamps MATSUSHITA ELECTRONICS CORP 19 April 1971 [3 March 1970] 22854/71 Heading H1D In a fluorescent discharge lamp having a rated lamp current of less than 125 mA the inside diameter B of at least one of the end tube portions which contains one of a pair of electrodes 3, 4 is between 8 and 13 mm. and the inside diameter A of the intermediate tube portion is between 6 and 8 mm. The electrodes 3 and 4 are coils containing an electron-emitting substance. Curves are provided (Figs. 2-5, not shown) showing the effect of the dimensions A and B on tube current, temperature at the closed end, relative brightness, light flux per unit length and relative light efficiency for lamps in which C = 15 mm. and l = 40 mm. Dimension B must be sufficiently large to prevent blackening of the envelope by oxides from the electrodes. The filling is mercury plus a rare gas at a pressure of several mm. Hg. and the tube wall should be maintained at a temperature of about 40‹ C. for optimumexcitation of the fluorescent coating 2. If the lamp is operated on D.C. only one electronemitting electrode is necessary and the other electrode may be a plain piece of metal. The dimension A is then maintained uniform to the end of the tube at which the latter electrode is located (Fig. 6, not shown).

Title: Improvements in and relating to electronic control circuits
IPC: H03F1/54
Filed: 1952-09-11
Abstract: 721,851. Pulse-generating circuits. GENERAL ELECTRIC CO. Sept. 11, 1952 [Sept. 11, 1951], No. 22857/ 52. Class 40 (6): In an arrangement in which a number of load circuits are recurrently energized from their respective storage circuits, changes in the impedance of a load are. reflected in the appropriate storage circuit to stop the energization of that load circuit. The invention is described as applied to a D.C. source feeding a number of delay lines, each being associated with a magnetron. A three-phase supply is fed over contactor 8 to transformer 10 and rectifiers 13 to give a D.C. supply at point 5. A pulse-forming network 3 is charged to twice this potential by means of a resonant inductor 15 and hold-off diode 16. Control pulses, fed in to cathode follower 17 fire thyratron 4 to discharge the network 3 through transformer 23 and hence energize magnetron 1. In the event of incorrect working, a residual negative charge remains on the network 3 so that diode 24 conducts and due to transformer 25, diode 27 conducts to establish a charge across the circuit 28. If the incorrect working continues, the rise in potential is ultimately sufficient to reverse the cathode-coupled flip-flop 30, 31 so that the anode potential of valve 31 rises causing thyratron 39 to fire and clamp the input to thyratron 4 thus preventing further firing. After a time determined by timeconstant circuit 34, 37 the flip-flop restores and thyratron 39 extinguishes to remove the clamp. Should the condition continue, capacitor 46 charges sufficiently for valve 48 to conduct and relay 49 to operate and open the circuit of contactor 8, 9. Contactor 8, 9 may have a locking contact to hold it in the open position until reset. Further magnetrons, such as 56, are provided with similar protective circuits, but it may be preferable for the valves 48 to operate relays 62 to cut off the triggering pulses to the appropriate cathode followers 17, 64. When a relay 62 is operated, it is held open by a locking contact until reset. Specification 692,405 is referred to.

Title: Fuel element
IPC: G21C3/32
Filed: 1971-04-19
Abstract: 1340577 Fuel elements KERNFORSCHUNG mbH GES FUER 19 April 1971 [7 March 1970] 22917/71 Heading G6C A fuel element for reactors with high and fast neutron flux, e.g. fast breeder reactors, comprises a prismatic fuel element box subdivided into compartments and containing a bundle of fuel pins, the compartments being located axially one behind the other and held together by tension members attached to the end compartments, or by fittings attached to the individual compartments. In the embodiment shown in Fig. 1, the ends of the compartments 4 are of reduced thickness and overlap, the gap between the overlapping parts being bridged by a cam integral with the respective inner part, the end of which is rounded. By this means, adjacent compartments 4 can tilt relative to each other. The compartments 4 are held together axially by tension bars 8 arranged along and around the longitudinal axis of the fuel element. The bars 8 are welded to fins 10 in the foot 9 of the fuel element, while in the head 11 they are flexibly anchored. The flexible anchoring serves to compensate for the differential elongation of the bars 8 resulting from material swelling, so that the stress distribution over the bars is uniform when the fuel element is withdrawn from the reactor core. A hinging effect is achieved by having the ends of the bars 8 bolted to an oscillating base-plate 12, the dishing 14 of which engages in a compensating element 15 to allow the plate 12 to be tilted relative to the element 15. The base-plate 12 is star-shaped in order to minimize the reduction in coolant flow. The element 15 is mounted on a spring 18 in a bore 17 at the centre of three fins 16 welded into the head 11. An alternative embodiment has no tension bars and the longitudinal forces are transmitted through the individual compartments of the fuel element box. In the regions of overlap, bolts welded to the outer parts engage with clearance in bores in the inner parts, there being a gap between the overlapping parts so that adjacent compartments can tilt relative to each other.

Title: Improved method and apparatus for treating sheet material
IPC: C14B1/40
Filed: 1960-06-30
Abstract: 895,028. Stretching sheet material such as leather. BLATZ, P. A. June 30, 1960, No. 23015/60. Class 76. Sheet material, the physical properties of which are improved by stretching, is stretched and suppled by the application of opposing forces which are laterally fixed relative to each other and to the sheet, these opposing forces being applied substantially perpendicularly to the sheet and upon opposite sides of it in spaced zones upon one side of the sheet and yieldably in a continuous zone upon the other side of the sheet in line with and in between the spaced zones, said opposing forces being strong enough to prevent any lateral movement of the sheet disposed in the path of said opposing forces which meet each other at said spaced zones and to force the length of the sheet disposed between said spaced zones out in the direction of the forces applied in the continuous zone to stretch said lengths. In an apparatus for carrying the invention into effect, a piece of leather 18 (Fig. 1) is drawn by the rotation of steel discs 14 which are from 3/16 to # inch in thickness into firm contact with the surface of an elastomeric body 12 which may be made from rubber of 10-50 durometer hardness. This body is firmly supported on a member 20 to apply a force which reacts against the contacting ends 13 of the discs 14 and the adjacent surfaces of body 12, thus causing the leather to be stretched and suppled at the same time. In a modification (Fig. 3) a substantially thick belt 12b of 30 durometer rubber about 4 to 5 feet in width is supported and rotated upon a pair of steel drums 34 which are mechanically rotated. Supporting drums 36 are rotatably mounted in contact with the lower surface 38 of the upper traverse of belt 12b. A series of rollers 40b, 42b and 44b successively repeated in that order are disposed along the upper surfaces of the upper traverse of the belt 126. Rollers 40b and 42b include spiral ribs 46b and 50b respectively which are of opposite hand one from the other to increase the suppling effect. Roller 44b is rotated by mechanically rotated pulley 52b and belt 54b at a peripheral speed higher than that of the belt 12b. Alternatively roller 44b may be allowed to rotate freely. In Fig. 9 a reciprocating projection means 60e is mounted above the surface of the rubber belt 12e, and a reciprocating means 64e is connected to a projection means 60e to move the projection means in and out of firm engagement. A series of projections 66e extend from the bottom of plate 62e and cause the leather (not shown) to be forced against the belt 12e which is itself supported by a force-resisting plate 68e. Compound rollers and rollers fitted with helical ribs set at 45 degrees may also be used.
