Title: Improvements in thrust bearings
IPC: F16C17/06
Filed: 1920-02-09
Abstract: 138,884. Kingsbury, A. Jan. 9, 1915, [Convention date]. Lubricant conveyed by mechanical means; cooling lubricant.-The upper bearing-shoes of n thrust bearing of the pivoted-block type are lubricated by oil which is raised by the rotating shaft collar 11 and delivered laterally by inclined grooves 18, 19, Fig. 1, formed on the edge of the collar. If the shaft is intended to rotate in both directions the grooves have the form shown in Fig. 4. The collar is formed with an annular groove 17 and is closely surrounded by a cylindrical casing 16. The oil descends through the spaces 28 between the shoes and returns to a reservoir 15 through passages 32, 36<a>, 37<a>, 22. The hot oil issuing from the bearings mixes with the circulating oil and is cooled. Cooling means may be provided in the reservoir 15. The oil is kept at such a level that the lower part of the collar 11 is immersed. Fig. 6 shows a modification in which the oil is deflected from the surface of a plain collar 11 by shoulders 37 at the ends of a recess 35 in the upper part of the casing 16. The oil returns to the reservoir through openings 41. The bearing consists of two semi-annular shoes 38 on each side of the collar 11, mounted on spherical pivots 39. The central sectors of the shoes form the bearing-surfaces and the end portions are depressed.

Title: Improvements relating to electric control circuits
Inventor: BURROWS GODFREY
IPC: G01N30/86
Filed: 1956-03-27
Abstract: 818,704. Switching arrangements. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. March 15, 1957 [March 27, 1956], No. 3999/59. Divided out of 818,703, [Group III]. Class 38 (4). In vapour phase chromatographic apparatus as disclosed in co-pending Specification 818,703, a plurality of fluid control valves are provided, the apparatus in use requiring that the valves be operated sequentially in order that the separated fractions may be collected into the respective collectors. The fluid control valves are electromagnetically operated by operating coils V  1 , V 2 , V 3 , each operating coil having associated therewith an operating relay OR, a setting relay SR and a change-over relay ChR, the relays SR and ChR being of the type which have two stable states. Initially the first setting relay SR1 and the third change-over relay ChR3 are in the picked-up condition as shown in the Figure. Upon energization of the circuit AB a control relay CR will be energized to operate an injection pump relay PR causing the injection pump to operate to charge the chromatographic apparatus. When the first separated fraction reaches a detector 23 an output signal therefrom appears at terminals 24, 25 which causes energization of the first operating relay OR1 thereby causing its front contact f to close. Thereupon the first changeover relay ChRl is picked-up and the valve operating solenoid V1 energized to operate the first valve to collect the first separated fractions. When the first fraction has passed the signal from the detector 23 disappears and the operating relay OR1 is de-energized to close its contact b thereby dropping down the setting relay SR1 and the change-over relay ChR3 and picking up the second setting relay SR2. The dropping down of relay ChR3 de-energizes the control relay CR to de-energize the pump operating relay PR. At the same time the closing of the contact b of operating relay OR1  de-energizes the valve operating solenoid V1  whereby the first valve is closed. When now, the second separated fraction reaches the detector 23 a further signal appears at terminals 24, 25, the operating relay OR2 is picked-up to close its contact f, whereby the second valve operating solenoid V2 is energized with the subsequent collection of the second separated fraction. When the second fraction has passed relay OR2 drops down and the cycle is repeated until all the separated fractions have been collected.

Title: Improvements in or relating to treatment of finely divided powders
IPC: C09C1/60
Filed: 1937-02-10
Abstract: Fine powders, such as carbon black, lamp black and similar forms of carbon, precipitated magnesium carbonate, calcium carbonate, zinc oxide, sulphur, barium sulphate, clays and talcs, are agglomerated into granules having a high apparent density by continuously advancing the dry powder along a predetermined course, and lightly pressing, rolling and gently tumbling it during its passage.  The powder is fed by a screw conveyer 36 into a revolving drum 10 divided into a number of compartments 11, 12, 13, 14, 15 and 16. the partitions having central holes 53...57. The drum is supported on rollers (not shown) and is frictionally driven by wheels 41.  In the first two compartments are provided long light rollers 58 and 59, of wood, rubber-surfaced metal &c., which are free to roll about the inner surface of the drum.  The effect of the rollers is to remove entrained air.  Baffles 60 having apertures 61 may be provided to prevent clogging and also to prevent dust passng into the other compartments.  The next compartment 13 may have a similar solid roller, or a wire screen roller of half-inch mesh.  The remaining compartments do not contain rollers, and may be smooth surfaced or lined with wire screen material.  These compartments give a gentle tumbling action and facilitate the formation of particles of substantially uniform size.  The agglomerated particles emerge through opening 52 and are led to conveyer 75 for packing, or they may fall on shaker screens 65 and 66 of suitable mesh, e.g. 20 mesh and 65 mesh per inch, whereby particles which are too large or too small may be separated and returned for further treatment.  The drum should be rotated only at <PICT:0475847/III/1> such a speed that the material will roll down the inner surface of the compartments, e.g. at about 10 r.p.m. and the supply is preferably controlled so that each compartment is about half-full. The final product has an apparent density of 20 to 25 lb. per cubic foot.

Title: Installation for transferring articles from one station to another
IPC: B42C19/08
Filed: 1972-01-28
Abstract: 1354634 Transferring signatures between gatherer and binder conveyers HARRISINTERTYPE CORP 28 Jan 1972 [14 May 1971] 4113/72 Heading B8A Signatures (not shown) are fed from a gatherer 10 to a binder 12, by pins 20 of a gatherer conveyer 18, pins 28 of a transfer conveyer 14, and pins 24 of a binder conveyer 22. The conveyer 14 is normally driven by both the gatherer drive-shaft 16 (Fig. 3) and the binder drive-shaft 42 running in synchronism by having clutches 40, 54, and 56 engaged. If it is necessary to shut down the gatherer, the clutch 54 is opened, and conveyer 14 continues to run until the signatures still in transit have been transferred to the conveyer 22. The conveyer 14 is then shut down by the action of photo-electric means 77. On restarting, the pins 28 on the conveyer 14 are brought into synchronism with the pins 20 of the conveyer 18, by having clutch 54 open and closing a clutch 72 between an auxiliary motor 74 and the drive shaft 62 of the conveyer 14. A cam 80 coaxially rotatable on the shaft 62, has a single lobe, the position of which, in relation to the circumferemtial length of the cam 80, corresponds to the spacing between adjacent pins 28 of the conveyer 14. The cam 80 is connected rotationally with the drive shaft 44 of the gatherer 10, and it is adapted to operate a switch 78 carried by a member rigid with the shaft 62. The switch 78 is positioned to correspond with the spacing of the pins 20 on the conveyer 18, and when operated by the lobe of the cam 80, simultaneously disconnects the clutch 72 and engages the clutch 54. The conveyers 18 and 14 are thus stationary but in synchronism. They are then restarted and brought up to the speed of the binder, when clutches 56 and 40 are re-engaged, and the system is then running normally, once more. There may be two gatherers and respective conveyers 14 feeding a single binder. When one gatherer needs to be shut down, the procedure described above is followed, while the other gatherer carries on feeding the binder normally.

Title: Improvements in or relating to machines for forming pig tails and inserting them into glass rods of incandescent lamps or similar devices
IPC: H01K3/10
Filed: 1925-02-13
Abstract: 230,431. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. March 6, 1924, [Convention date]. Filaments, supports for; residual gases.-Conprises a machine wherein looped wire supports are formed and are transferred by grippers from the coilers to a zone where they are sealed into a glass rod. Wire is fed from a series of reels 53 by rollers 23, operated intermittently and simultaneously by a chain 32. This is operated by a cam on a main cam-shaft 21 through a link 43 and a one-way clutch 36. The wires are fed through guides to coilers 63, Fig. 10, which form loops around mandrels 65. One or two wires may be fed by each pair of rollers. Grippers 145, 146, Fig. 12, oscillating about horizontal axes 135 transfer the formed supports from the coilers to the sealing-in position 7, Fig. 1. When the coiled wires have been seized, thev are severed from the supply wires by cutters 116, Fig. 10, actuated by shafts 113, while the mandrels are simultaneously withdrawn from the coils by springs 94 when released from the pressure of fingers 97, 109, Fig. 1. These fingers are operated or carried by a chain of links 100 adapted to be reciprocated by a cam on the shaft 21. A rod projects through a hole 110 in each link 100 and is thereby moved to actuate the shaft 113 of the wire cutter. The grippers are oscillated by bevel-bearing 131, 132, Fig. 12, the wheel 132 being fixed on a sleeve 133 on which the carrier 140 of the grippers is frictionally held by a spring-pressed plunger 141. A wedge 138 is secured by arms 137 to the wheel 132. When the open grippers embrace a wire they are stopped, while their frictional connection with the sleeve 133 allows this to rotate farther and move the wedge 138 to allow the grippers to close, the reverse action occurring when the wires have to be released after being sealed in the glass stem. In the case where two wires are fed together to duplicate coilers, the grippers are also duplicated with a central jaw 145 common to both. The glass rods are mounted in grippers slidable vertically on rods 152, 158, Fig. 2, spaced around a rotatable carrier 8, the level of the grippers being determined by rollers running on a track 197. After the rods have been preliminarily heated and " jumped up " by a vertically acting pusher to start the formation of " knobs " for the insertion of the wire supports, in which operations a conical end is formed on the rods, they are brought into position above a conical cup 7, Figs. 1 and 2, and a section 198 of the track 197 is lowered to compress the rod and so complete the swelling out of the knob, whereby the wire supports become embedded in the knob. At the same time the end of the rod has a roughened swelling formed by the cup or die 7 to form a surface specially adapted to receive a " getter " in the finished lamp.

Title: Sampling device particularly suitable for filter tip cigarettes
IPC: A24C5/34
Filed: 1968-01-29
Abstract: 1,144,740. Cigarette sampling device. AMERICAN MACHINE & FOUNDRY CO. 29 Jan., 1968 [2 Feb., 1967], No. 4426/68. Heading A2C. An automatic sampling device for the periodical collection of cigarettes issuing from a cigarette-making machine as two sets S1, S2 on an endless conveyer 1 alternating as shown, comprises a rotating suction drum 4 by means of which one set S1 is transferred to one collecting box C1 and the other set S2 is transferred to another collecting box C2. The row of cigarettes S1 S2 may comprise the single row formed by bisecting double length cigarettes to form two rows, turning one of these two rows and interposing the cigarettes in the turned row between the cigarettes in the unturned row. Suction is fed to opening H1 in alternate flutes in the drum 4, controlled in conventional manner to apply suction over the sector A-B, to pick up cigarettes in set S1 and transport them to a suction transfer drum 14 which deposits them in the box C1 Similarly suction is applied to openings H2 over the sector A-D to transfer cigarettes of set S2 to the box C2, the position of D being adjustable by means of a valve sector 15. A valve piston 17, in one position, interrupts the supply of suction to the openings H1 H2 in the section A-L of the sectors A-B, A-D. The piston 17 is electromagnetically operated to successively open and close a suction intercepting valve (12) in response to actuation of a micro switch (30) by two cams (31, 32) mounted on the drum 4 and spaced 180 degrees apart. Thus, when suction is applied to the drum 4 for sampling, cigarettes are normally only picked up during a half revolution of the drum 4. By means of suitable control circuitry the number of cigarettes picked up may be varied, in multiples of the number picked up in one half revolution of the drum 4, by closing the valve (12) only after a predetermined number of pulses from the micro switch (30).

Title: Improvements in or relating to rebound checks for firearms
IPC: F41A3/70
Filed: 1943-03-18
Abstract: 579,196. Automatic firearms. BRITISH MANUFACTURE & RESEARCH CO., Ltd., and ASHWORTH, F. R. March 18, 1943, No. 4448. [Classes 92 (ii) and 119] A rebound check for a fast forwardly-moving part of an automatic gun, e.g. the unlocking plates of an Hispano gun or a breech-block, comprises an inertia member E mounted with endwise freedom in the part B, the rebound of which is to be checked when it makes contact with the end wall C<1> 1 of the casing, or other fixed part of the gun. The member E is recessed and provided with inclines K. A snubber J with mating inclines L is mounted in the recess and is transversely constrained by a slot S in the part B. When the part B strikes the abutment C<1> at the end of its forward movement, the inertia member E continues its movement and the inclines K, L coact and force the snubber J outwards into binding contact with the top wall of the receiver A, the part B being also thus forced downwards to engage frictionally with the breech-block N or casing A. Bounce is thus prevented, but the spring F reacts at once to re-set the member E and release the 'snubber. Extra weight may be added to the inertia member by fixing a mass G to it.
