Title: Chuck apparatus
IPC: B65B21/12
Filed: 1974-05-08
Abstract: 1467464 Conveying containers ANCHOR HOCKING CORP 8 May 1974 [10 May 1973 12 Oct 1973] 20370/74 Heading B8A [Also in Division CI] Glassware &c. containers 22 placed on holders 14 of a rotating turret 12 are lifted into engagement with a chuck 16 which is one of an endless series carried by a conveyer chain 46. They are then carried by this means through a coating station (not shown) and are returned to holders 14 on another turret. The chuck 16 comprises four gripping jaws 26 each pivoted at 48 on a fixed body portion 45a. A lip 49 on each jaw engages beneath a bead 54 of the finish portion 24 of the container 22 when the portion 24 has entered the jaws 26. The latter move to an open position under centrifugal force, by rotation of a suspension rod 34 of the chuck, brought about by the rod 34 engaging a fixed rail 80. The pivots of each jaw 26 may be arranged relative to the e.g. of the jaw so that the latter tend to hang in an open position. Alternatively they may be arranged to hang in a closed position. The containers 22 are lifted up to the chucks 26 by the action of a cam 32 (Fig. 1) as the conveyer chain runs into alignment with the path of the holders 14. A cam wheel 62 and track 66 (Fig. 2) on the turret, respective to each holder 14, co-operates to lift each successive chuck after the latter has been engaged by a forked member 68. This action also lifts a sleeve 53, a portion 52 of which normally engages the chuck jaws to keep them in the closed position. After the containers 22 have been conveyed through the coating station, they are deposited on another turret 12 by the above process in reverse. The chuck jaws are opened by cam action (Fig. 8, not shown) or by tilting of the container (Fig. 7, not shown). A modified form of chuck (Fig. 9, not shown) is described, for engaging containers having a reduced diameter finish portion.

Title: Improvements in and relating to coke ovens
IPC: C10B7/14
Filed: 1936-07-23
Abstract: 478,960. Carbonizing-apparatus. HELLMANN, O. July 23, 1936, No. 20443. [Glass 55 (i)] In an oven for coking fuel supported directly on a stationary heating surface in flat moulds without base plates and which are movable on the heating surface, the moulds traverse a closed path within the oven, adjacent stationary filling and emptying points being provided therein. The moulds may follow a circular track or a pair of forward and backward longitudinal tracks. A number of sector-shaped moulds e united to form a circular arrangement by means of an outer peripheral toothed ring, move over stationary circular heating surfaces, a number of such units being superimposed within the oven. The coked material is discharged through registering openings in the heating surfaces through a common delivery f on to a conveyer f<1>. The moulds are then ready for filling from a common hopper a which supplies the fuel to each of a number of corresponding loading boxes d by means of conveyers c. The outer toothed rings are driven by engagement with gear wheels g carried on a common shaft. The heating gases from the lowermost unit flow through the superimposed units with addition of fresh hot gas if desired. Cover plates s may be mounted over the moulds, movable in a vertical direction only, to inhibit dilation of the fuel and to insulate the upper parts of the moulds. In a modification of the invention, the circular tracks are replaced by superimposed tracks forming two sets of forward and backward longitudinal heating oven units b, a, Fig. 3, respectively. Movement of the moulds 1 from one track to its parallel track or along the track is effected by means of plungers actuated by external machines 12. The coked material is discharged through gaps in the units into a common delivery 10 by means of projections on the undersides of plates 9, Fig. 6, which strike the material in the moulds repeatedly. The moulds are then filled from a common hopper 5, Fig. 5, connected to a discontinuous shaft extending through all the units. Burners 16 and auxiliary burners 17 are provided to supply heating gases to the superimposed units. The fuel is preferably pre-heated to 100-250‹ C. before introduction into the moulds.

Abstract: 464,677. Seats. FITZMAURICE, D. F. H. July 18, 1935, No. 20457. [Class 52 (ii)] A seat frame of tubular metal has a seating portion a, Fig. 1, and a backrest portion b independently supported by a resilient frame or frames so arranged that upon yielding of the back-rest beyond a predetermined amount the back-rest frame abuts against a member of the seat frame and is partially supported thereby. Similarly, when the seat frame a yields beyond a predetermined amount it abuts against a member of the back-rest. As shown, the frames a and b of the seat and back-rest are connected by a slotted link d which allows independent yielding by either frame up to a definite amount; on further yielding the loaded frame is partially supported by the other frame. Fig. 5 shows a construction in which the seat frame c<1> passes through loops d<1> in the back frame e<1>. The frames may be secured together, or may be integral, where they are secured to the floor. In the forms shown in Figs. 1 and 4, the back-rest frame is pivoted at f so that it can be tilted forwardly ; the links d permit the tilting, but in this case the back rest frame does not assist in supporting the seat frame, on flexure of the latter. In a double seat, Fig. 4, the intermediate frame h may be spaced unequally from the ends. The upholstery may be of the hammock type, and may comprise pneumatic cushions.

Patent GB-734021-A (GB)
Title: A process for the synthesis of high boiling viscous hydrocarbon mixtures
IPC: C07C1/04
Filed: 1952-08-15
Abstract: Viscous, high-boiling hydrocarbons are produced by contacting a synthesis gas containing CO and H2 with a finely-divided, moving catalyst, the main constituent of which is a Group 8 metal and/or oxide, at superatmospheric pressure and at temperatures of 180-400 DEG  C., separating from the product a fraction boiling above 340 DEG C., and subjecting this to catalytic hydrogenation, preferably at a partial pressure of hydrogen of 20-50 kg./sq. cm. and 230-270 DEG C., especially 30 kg./sq. cm. and 250 DEG  C. Oxygen-containing groups and unsaturated bonds are thereby eliminated and cyclic compounds partially decyclized.  Prior to hydrogenation, the separated fraction may be diluted with hydrocarbons of 4-15 C atoms, especially C7-C9 hydrocarbons.  The hydrogenated product may be cooled to separate wax-like hydrocarbons, freed by distillation of products boiling up to 340 DEG  C., and solvent extracted, if desired, to give a lubricating oil.  The synthesis may be effected with fluidized catalysts, generally of above 0.25 mm. size, using 400-2000 g. per litre of fluidized catalyst layer or with suspended catalysts of 0.04-0.25 mm. size using 15-300 g. per litre of synthesis gas flowing at 50-13,000 cm./sec. or more.  The ratio CO : H2 may be from 1 : 1 to 1 : 3.  The catalyst may include iron, cobalt or nickel, non-reducible oxides as activators, and carriers.  The catalyst used for hydrogenating the separated fraction may be the synthesis catalyst or, for example, nickel - magnesia - kieselguhr, Raney nickel, molybdenum or tungsten sulphide.  In examples: (1) the product boiling above 340 DEG  C. prepared from CO+H2 at 325 DEG  C. and 17 atmos. using a suspended iron catalyst is autoclaved with a nickel-magnesia-kieselguhr catalyst and a 3 : 1 H2-N2 mixture at 250 DEG  C. and 50 atm., the product filtered, fractionated to separate hydrocarbons boiling up to 340 DEG  C., the residue mixed with dichlorethane, cooled to -25 DEG  C. and filtered to give a ceresin-like product and a lubricating oil; (2) a product boiling above 343 DEG  C. prepared as in (1) except that the temperature is 360 DEG  C., is similarly hydrogenated while mixed with a saturated C7 fraction of the synthesis product, cooled to -10 DEG  C., filtered, distilled to remove the C7 diluent, and then vacuum distilled to yield a fraction boiling at 100-340 DEG  C. which can be separated into gasoline and diesel oil, and a heavier residue of lubricating oil.

Title: Improvements in or relating to a sheet deliverer for printing machines
Inventor: WOLF HELMUT
IPC: B65H29/08
Filed: 1955-07-18
Abstract: 798,079. Sheet-delivery apparatus. VEB DRUCKAUTOMATENWERK. July 18, 1955, No. 20708/55. Class 100(1) In a sheet delivery device for removing a sheet from the impression cylinder of a printing machine the removal is effected by suckers 6 which are reciprocated between the removal point and a delivery point, and in addition the feet of the suckers are given a rotational movement such that they ride on the periphery of cylinder at substantially the same peripheral speed as the cylinder during the sheet removal. The suckers 6 are mounted on a bar 5 rotatably carried by a lever 11 which guides the bar 5 in a rail 13 between the points 7 and 8. The bar 5 is reciprocated by the bar 11 through a lever 14, pivoted at 15, bar 16 and crank 17. The crank 17 is rigidly connected to a cam disc 18, which, through cam follower 16 and linkage system 20, 21, 29 causes rotation of the bar 5 when it reaches the position 7 in such a manner that the feet of the suckers 6 rotate at substantially the same speed as the peripheral speed of the impression cylinder 4 to pick up the leading edge of a printed sheet and remove it tangentially from the cylinder. The linkage system 20, 21...29 is pivoted to the lever 14 at 24 and is arranged so that the point 30 of linkage system coincides with the pivot point 15 in the middle of the stroke of the lever 20. The rail 13 may be curved slightly or may be pivoted at 8 and the lower end given a slight oscillatory movement.

IPC: G01C19/36
Filed: 1954-07-16
Abstract: 772,090. Electric gyro compass systems. SMITH & SONS (ENGLAND), Ltd., S. July 14, 1955 [July 16, 1954], No. 20853/54. Class 40 (1). A compass system comprises a gyro controlling the angular position of a first shaft directly and a second shaft through a differential selsyn link which may be preset for a given craft bearing, the angular position of the second shaft being compared with the bearing as given by a magnetic compass, whereby any discrepancy may be used to process the gyro except when the rate of turn of the craft is excessive, or when the magnetic compass is unreliable. As shown, the heading of a craft as determined by the gyro 1 which positions the rotor of a selsyn device 3, is indicated by a shaft 5 attached to the energized rotor of a further selsyn 6, the stators of selsyns 3 and 6 being connected to a differential selsyn 8 whose windings are manually settable, so that any discrepancy between the angular positions of the rotors of 3 and 6 produces a signal in the rotor of selsyn 3 which is amplified at 9 to energize motor 7 to reposition shaft 5, and the rotor of selsyn 6 to eliminate the error signal. A further shaft 10 is also brought into positional agreement with shaft 5 by a selsyn 11 whose stator is connected to that of selsyn 6, error signals being amplified at 12 to energize motor 13 to drive the shaft 10 and rotor of selsyn 11 to eliminate the error signal. The heading of the craft is also determined by the magnetic detector 14, and is compared at 15 with the angular position of shaft 10, indicating the heading as determined by gyro 1, any discrepancy appearing as a signal, amplified at 16 and energizing torque motor 2 through switches 17, 18 to precess the gyro 1. When the rate of turn in azimuth exceeds a predetermined value, a rotation-sensitive switch 21 on shaft 10 closes contacts to energize relay 22 to open switch 18, and also energizes relay 23 which opens a switch 24 in an alarm circuit. The above system is duplicated at 100 and a selsyn 20 attached to each shaft 5 give a discrepancy signal when they disagree which is amplified at 28 to energize a relay 29 to close switch 30 in the alarm circuit. Switch 17 is manually operable to disconnect the magnetic detector 14 when unreliable, e.g. in polar regions. Specification 586,506 is referred to.

Abstract: 616,713. Control of two motors. HALVORSEN, K. R. July 12, 1946, No. 20884. Convention date, Oct. 11, 1944. [Class 38 (iii)] [Also in Group XXX] A control system for a grab hoist wherein two-wire grips are associated with separate hoisting and closing motors each having a separate controller, comprises a push-button 33 connected with switches 16 and 19 for automatically switching the hoisting motor on and off when the push-button is actuated and the hoisting controller 40 is in the " off " position, said switches being operated in accordance with the varying tension of the hoisting-wire. During lowering and loading of the grab means are provided to prevent excessive slackening of the hoisting-wire, so enabling the grab to penetrate the load. When the hoisting-line is taut a, weight 36 is in its upper position and switches 16 and 19 are closed to close a relay 38 and enable the hoist motor to be energized for lowering. As the hoisting-line slackens the weight 36 descends and the switch 16 opens but the relay 38 is maintained over contacts 23-26. Further slackening of the hoisting- wire opens switch 19 to stop the hoist motor which is re-started when the hoisting-wire has been tensioned sufficiently to allow the grips to hold the load safely. If the closing wire is slackened a weight 37 will drop to open a contactor 39 for the closing-motor, the closing- wire being again tensioned due to the lowering of the load by the hoist motor. The load may be allowed to overhaul by closing contacts 1-4 to remove an electromagnetic brake.
