Title: Apparatus for forming stacks of articles for packaging
IPC: B65G57/00
Filed: 1965-07-19
Abstract: 1,112,364. Packaging-machines; endless conveyers. AZIONARIA COSTRUZIONI MACCHINE AUTOMATICHE ACMA S.p.A. 19 July, 1965 [18 July, 1964], No. 30507/65. Headings B8A and B8C. Apparatus for forming progressively piles of biscuits &c. preparatory to wrapping, comprises conveyer means receiving parallel rows of biscuits, e.g. from an oven and stacking them in magazines, from the bases of which they are fed into compartments moving along the line of magazines to each receive biscuits from each magazine, the number of biscuits fed at a time from each magazine being capable of variation as between one feeding operation and the next. The biscuits are progressed from the oven by parallel belts 3, diverging channels 2 and further parallel belts 1, 5, the latter being separated by gaps V to permit faulty biscuits to fall down a shoot 7 into a receiver 8. In the event of a hold up beyond the belts 1, the latter may swing downwards and the shoot 7 pivot to divert the oven output to a receiver 12 (see also Fig. 1a, not shown). The biscuits pile up in a row of magazines 6, the base of which is formed by a common support 13 in the form of a series of fingers. A comb-like common pusher 14 operates through the gaps between the fingers to discharge biscuits into compartments 15 on a chain conveyer 16 as these move past the magazines. The support 13 is adjusted vertically for each pusher stroke, its upper limit being determined by a cam 17 and its lower limit, i.e. that controlling the number of biscuits to be fed on the next stroke, depending upon a programming cam 19. Thus each of the entire group of hoppers may distribute at one stroke say, two biscuits and at the next three and so on as required. As each compartment fills, so its base 15a is lowered by a cam track 35, Figs. 2, 3 (latter not shown). Feelers 36, 37 monitor the compartments (see again Figs. 2, 3) to enable the number of biscuits to be made up or reduced by horizontal feeders 38, 39. Finally, as the conveyer passes round the end sprockets, a transverse pusher empties each charge into a pocket on a further conveyer 40, lined with wrapping material by a vertically reciprocatng former. In an alternative embodiment, Fig. 7 (not shown), groups of three magazines each feed a compartment 15 to produce in it, three stacks side by side. An alternative means for producing cyclical variations of the height of the support 13 includes linkage means having variable pivot points formed by arcuate slot connections, Fig. 4 (not shown). A pin wheel having axially projecting radially arranged and manually withdrawable pins may replace the cam 19 in a further arrangement, Figs. 8, 9 (not shown). The compartments may be continuously movable, the magazines and feeding device moving with them during the feeding stroke (not shown or detailed).
Patent GB-747201-A (GB)
Title: Improvements in or relating to hydraulic tipping gear for load carrying vehicles
IPC: B60P1/16
Filed: 1953-11-05
Abstract: 747,201. Hydraulic control systems. PILOT WORKS, Ltd., and THISTLETHWAITE, K. Oct. 27, 1954 [Nov. 5, 1953], No. 30561/53. Class 69 (2). A tipping vehicle is provided with an hydraulic assembly for raising the body and agitating it when it is in its inclined position. For this purpose a pump 2 pumps oil from a reservoir 5 to ram cylinders 1 for raising the body. The flow from the pump 2 is through a valve unit mounted in the reservoir and which comprises a spring-loaded conical valve 21 which normally closes an opening 22b communicating a through bore 23 in the pump line to the ram cylinders with holes 29 venting into the reservoir. Also connected to the pump line to the cylinders 1 is a further connection 11 leading to the remote end 17 of the valve unit and in which line is incorporated a valve 12 actuated by the body of the tipping vehicle when it reaches the desired inclination. Actuation of the valve 12 allows pressure oil to enter the cylinder 15 of the unit and to force a piston 16 to move so that a projection 20 engages the end of the conical valve 21 and opens the bore 23 to the vent holes 29, whereby the pressure oil from the pump and cylinders vents to the reservoir. The relief of pressure oil to the cylinders causes the body of the vehicle to fall slightly, thereby closing valve 12. The spring 26 engaging the conical valve 21 then urges the piston 16 in the reverse direction, it being permitted to so move by the provision of a bleed valve 18, and the valve 21 closes the opening 22b preventing the venting of the pressure oil. The body of the vehicle is therefore further raised and the sequence repeated, thereby causing agitation of the body.

Title: Improvements in electric rheostats
IPC: H01C10/18
Filed: 1924-12-19
Abstract: 242,807. Crompton & Co., Ltd., and Jones, W. F. Dec. 19, 1924. Variable resistances.-- Electric contact is made with the periphery of a convolution of a helically wound wire, by means of a grooved ring A, Fig. 1, having spring means for keeping it in contact with the wire. The ring is provided with flanges C coupled together by a screw D fitted with a spring washer F. The flanges may be integral with or separate from the ring and the washer F may be omitted if the spring in the flanges is sufficient. The ring may be of any section and may he turned from a tube or plate or may consist of a piece of wire bent to shape on a former. A rheostat, Fig. 10, comprises a porcelain cylinder L provided with a helically wound wire N and mounted on a spindle J fitted with a hand wheel K and carried in bearings H, Y on a base plate G. A grooved contact ring A engages one turn of the wire and is guided longitudinally, when the hand wheel is operated to vary the resistance, by a bar W carrying one of the supply terminals. A second grooved contact ring A. secured to a terminal V, engages a metal disc Q to which one end of the wire N is secured. In a modification comprising two parallel resistance cylinders the bar W is omitted, the rings A embracing the wires N being interconnected. The disc Q may be omitted if the wire N be connected to the spider M. The baseplate may then function as a terminal if the handwheel and bar W be insulated. Alternatively, the bearing Y may be used as a terminal if it be insulated from the base-plate. In this case the spindle J is not continuous or is fitted with an insulating section. Specifications 4573/78 and 161,746 are referred to.

Filed: 1950-12-18
Abstract: 709,203. Cigarette-making machines. MOLINS, D. W.. RUAU, F. F., JACKSON, N. W., and MOLINS MACHINE CO., Ltd. Dec. 18, 1951 [Dec. 18, 1950], No. 30796/50. Class 130 An adjusting element 22a, which enters the path of a composite filler, consisting of alternate mouthpiece stubs and tobacco sections, behind a stub and moves forward faster than the stub to ensure correct positioning thereof, comprises a thin bladelike element which can pass through at least some of the tobacco in its movement towards the stub. A tobacco filler, formed on a conveyer 2, is cut by a knife 7 into sections which are spaced apart by a cigarette paper web 20 moving faster than the conveyer 2, a cam-shaped member 17 helping to accelerate the tobacco sections up to the speed of the web 20. The stubs are removed from a fluted wheel 15 by cam-actuated fingers 12 projecting from a transfer wheel 9 which deposits the stubs in the spaces between the tobacco sections, a scraper shoe 18' preventing tobacco or stubs from being lifted by the wheel, which wheel has a peripheral speed slightly greater than that of the web 20 to cause such stubs to abut against the preceding tobacco section. The composite filler passes beneath the garniture tongue 21 through a slot in which the fingers 22a pass into the path of the filler. Each thin' finger 22a, Figs. 1 and 3, fixed to a rotary wheel 22, moves at a greater speed than the filler and is associated with a thick tobaccoadvancing finger 22b. The finger 22a enters the filler a short distance behind a stub and moves through the tobacco without advancing the tobacco until it contacts the stub which it then correctly positions. The finger 22b enters the filler behind the finger 22a and advances some tobacco to close up any gap between a tobacco section and the preceding plug. The composite filler then passes to the usual wrapping and cutting mechanism. An intermittently operating blower 27 blows tobacco dust from the spaces between the tobacco sections before insertion of the stubs, the dust being collected by a suction nozzle 28. Specifications 669,559, 685,761, 709,197 and 709,198 are referred to.

Abstract: 912,294. Toy guns and cartridges. RYAN, J. W. Sept. 11, 1959 [March 9, 1959], No. 31103/59. Class 132 (3). [Also in Group XXI] A toy cartridge comprises a case 11 of metal or plastic, having an inwardly-projecting shoulder at its open end, which engages hooks on a releasable retainer on the plastic pellet 12. A propelling coil-spring within the case presses against a solid or bifurcated stem 32 on the pellet. The shoulder may be interrupted so that relative rotation between the case and pellet releases the hooks but, as shown, when the gun is loaded a small clearance is left between the mouth of the breech and the rear flange of the cartridge, so that on firing the firing hammer forces the cartridge further into the chamber and outwardly-extending cam faces on the releasable retainer engage an annular shoulder 59 in the cartridge chamber, which squeezes the retainer inwardly and thereby disengages the hooks from the case. The cartridge may have a percussive cap struck by the firing hammer. Specifications 912,295 and 912,296 are referred to.

Filed: 1953-11-11
Abstract: 759,514. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., and KESTELL, T. A. Nov. 10, 1954 [Nov. 11, 1953], No. 31195/53. Class 89 (3). In a fastening inserting machine, for example an insole tacking machine, a driver 1 operated by a spring 34 is cocked and released by an actuating member 46 which is rocked to and fro as desired by depressing a treadle so as to couple it to a continuously rocking member 88 driven from a shaft 98. The member 88 carries a fixed catch plate 100 and a spring-pressed catch plate 102 (not shown) rockable about a pivot 110 which co-operate respectively with spring-pressed pawls 82, 84 pivoted at 78 on a lever 80 which is coupled by a link 54 with the actuating member 46. The pawl 82 and, through a pin 118, the pawl 84 are normally held out of engagement with the catch plates by a release lever 120 engaging the tail 134 of the pawl 82, but are released when the lever 120 is moved clockwise against a spring 126 by means of latches 146, 148 pivoted on a treadle arm 138. The latch 148 is disengaged from the lever 120 after a single operation of the driver 1 by a stop screw 160 on the lever 80. If, however, the latch 148 is moved to an inoperative position by adjusting an eccentric 166, the latch 146 becomes operative and the driver 1 will continue to operate until the treadle is released. The driver 1 is mounted on a bar 6 and is operated by the adjustable spring 34 through a lever 19 and a strut 18 held in position between the lever 19 and bar 6 by springs 22 connected to an adjustable head 8. When the actuating member 46 is rocked clockwise, a lug 56 co-operating with a lug 58 rocks the lever 19 which is then held cocked by a spring-pressed pivoted latch 64 engaging with a downwardly extending lug 72 of the lever 19. When the actuating member 46 returns to its original position, it engages an arm 66 on the latch 64 to disengage it and permit operation of the driver. Specification 29224/06, [Class 17], is referred to.

A fastener for holding the cranked-end 36 of a shaft 35 within an aperture 42 in a member 41, so that the member may pivot about the crank while relative axial-movement of the crank and member is prevented, consists of a U-shaped spring-clip 28 having a web 29 and two limbs, each of which is bifurcated to form a pair of snap-engaging-arms 30, 31. In use, the crank 36 is passed through the aperture 42 and this assembly is forced laterally into the clip, the crank-parts at each side of the aperture entering lead-in-gaps 32 so that the arms 30, 31, spring apart to allow the crank to enter between arcuate portions 33, 34, which are of smaller radius than the crank. The arms then snap together, the pointed prongs 37, 40, at the ends of the arcuate portions gripping the crank to prevent radial movement thereof with respect to the member 41. Each bifurcation of the snapengaging-arms extends into the web 29, so that the latter acts as a leaf-spring, increasing the engaging-force of the arms.

Title: Separation of sec-butyl ether from butylene codimers by distillation
IPC: C07C41/42
Filed: 1956-10-15
Abstract: <PICT:0826260/III/1> Secondary butyl ether, obtained as a byproduct in the synthesis of secondary butanol by the catalytic hydration of butylene, is separated from butylene codimers, i.e. various trimethylpentenes, by submitting the mixture to fractional distillation at a pressure of 5 to 40 atmospheres, preferably about 10 to 20 atmospheres, whereby the codimers are obtained as distillate and the purified ether is obtained as bottoms fraction.  Crude secondary butanol, obtained by the hydration of butylene is introduced through pipe 1 into distillation tower 2; and "butyl heads," comprising secondary butyl ether, secondary butanol, butylene codimers and butylene, are taken off via line 3.  The vapours are scrubbed with water in scrubber 4.  The aqueous alcohol so obtained is passed to tower 2 via line 5.  Crude butanol-water mixture is withdrawn from the base of tower 2, and is led to a purification unit.  The washed butyl heads, withdrawn from the scrubber, are passed through pipe 7 into fractionating column 8, wherein the mixture is fractionated under the pressure of 10 to 20 atmospheres. The codimers are taken off overhead, employing a reflux ratio of about 3 to 1.  The purified ether is withdrawn via pipe 10.
