Title: Apparatus and method for orienting and case packing eared containers
IPC: B65B5/08
Filed: 1974-06-25
Abstract: 1462817 Packaging eared containers in cartons; endless conveyers R A HEISLER 25 June 1974 [26 June 1973] 28180/74 Headings B8C and B8A A container or containers is/are fed into each end of a carton by pushers 116 having fingers 122, 123 and arms 128, 129 to engage and hold ears 33 which support or are for supporting bails on the containers. In the embodiment shown, as a pair of containers are pushed into an end of the carton the edges of the container move under pressed plates causing the containers to rotate so that an ear on each container moves under the end of a pivotally mounted finger 122 or 123 and engages an arm 128 or 129 which slides over the container surface. There is a separate container feed conveyer on each side of the carton. Containers may be guided from a single supply conveyer to the feed conveyers by a rail which engage the bails extending vertically upwards from the container, a diverter (80, Fig. 6, not shown) being swung by each container as it enters one feed conveyer to deflect the bail of the next container along the other conveyer. Alternatively each feed conveyer may have its own bail attaching apparatus and have a rub rail to rotate each container until an ear on the container engages a stop rail. In this case then is a single finger on each pusher arranged to be positioned between the ears of a pair of container and the arms clamp the ears against the finger. If only one container is pushed into each end of a carton half the pusher shown in Fig. 8 is used. Suction grippers feed a carton blank from a magazine and erect it. Following container insertion glue is applied to end flaps after they have been folded in and a pneumatic actuator (187, Fig. 19, not shown) then pivots further arms (195, 196) to fold in the remaining end flaps. The flaps may be stapled instead of being glued.

Abstract: 646,834. Gear.wheel pumps. WILMOTBREEDEN, Ltd., STEPHENSON, C. H., and DE LA RUE, W. A. Oct. 30, 1948, No. 28221. [Class 110(ii)] [Also in Group XXIX] A reversible pump is pivotably mounted and may be rocked in either direction to be driven by a fly-wheel of a vehicle engine, or other source of motion. As shown, a jack p is supplied with liquid by a pump having gears a with external pulleys, one of which pulleys is moved into contact with a flywheel g, or other rotor, by working a bracket e about a pivot f. Pipes c, d act as supply and return lines to the jack cylinder and liquid may be drawn from a tank r, or returned thereto, under control of a shuttle valve s. If c is the delivery line, liquid pressure moves the valve s to the left. A rod i may be moved to rock the bracket e, spring k holding the rod in its neutral position until the jack is required. The rocking motion is assisted by pressure liquid forcing out one of the plungers n into contact with an abutment o. The jack may be used to move a motor-car hood, or to lift the vehicle.

Title: Improved watering device
Inventor: MURPHY JAMES
IPC: B05B3/04
Filed: 1957-09-09
Abstract: 889,869. Rotary sprayers. BRITISH OVERHEAD IRRIGATION Ltd. Dec. 8, 1958 [Sept. 9, 1957], No. 28385/57. Class 69 (3). A rotary spray head with nozzles 20 has a tube 30 extending into a chamber 24 of a stationary hollow body 14, and the tube is flanged at 32 and has lugs 36, Fig. 3, extending therefrom. A turbine wheel 40, Fig. 4, is loosely carried in the chamber 24 and has vanes 42 by which it is rotated, and lugs 44 for engaging the lugs of the spray head when water under pressure is supplied to the sprayer at 26. In operation, water is forced through the body via passages in a flow-controlling element 52, Fig. 5, and passes through the tube 30 to the nozzles; water pressure forces the flange 32 upwardly against a cap 28 of the body, and also causes the turbine wheel to loosely engage the lugs of the spray head. The wheel rotates at a comparatively high speed, and the faces of its lugs knock against the faces of the spray head lugs to rotate the head relatively slowly. The jets 20, and a passageway element 57 in the element 52 may be replaced by others of different size. In the embodiment of Fig. 6, a turbine wheel 86 is a loose fit on a tubular portion 78 of the spray head, and rests on a star wheel 88 secured to the tubular portion extending into the chamber 81. The wheel is rotated by its raked vanes 90, Fig. 9, and has inclined faces 94 which, in operation, knock repeatedly against the lobes 89 of the star wheel to thereby drive the spray head relatively slowly. Water passes through opposed passages 100, 102 and against the vanes of the turbine wheel, and a valve 98 controls the flow of water to the chamber 81. A number of such devices may be fed from a supply pipe located below ground level, with the nozzles arranged just above the ground; the chamber 81 and the tubular part 78 are longer so that, in operation, water pressure raises the spray head above ground level. When inoperative, each head is housed in a cup carried from the main body of the device and a disc carried by the head provides a cover for the cup.

[Also in Groups XX and XXIV] In linkwork ensuring that a device, such as a camera, lamp, lens, pen or windscreen wiper, carried by a bracket 26 moves only in a straight line and remains parallel to itself, the bracket 26 is supported from a bracket 18 on a fixed stand 19 by two pairs of equal length parallel rods 15, 16 and 24, 25 pivoted on an intermediate member 21, the rods 16, 24 being coupled by means such as gear segments 29 so that they move through equal angles in opposite directions. Alternatively or additionally the rods 15, 25 may be similarly coupled. A spring 31 may be provided between rods 15, 25 to counterbalance the member 21. Alternatively counterweights or frictional joints may be employed. As shown, the bracket 17 is fixed to a tube 18 clamped to the stand 19, and the bracket 26 has a tube 27 for carrying a lens. Alternatively the bracket 18 may be rotatable on the stand 19 and rest against an adjustable collar thereon so that the lens may be traversed in a plane parallel to a surface 30 to be examined. To avoid interference between the rods when brought together the line joining the pivots on the bracket 17 is is inclined to the vertical. The two pairs of rods may be in different planes to allow them to pass one another. In a modification, the gear segments 29 are replaced by discs 37, 38, Fig. 4, on the ends of the rods 16, 24, the two discs being coupled by a strip of material or by intermeshing nylon threads 39, 42 attached to and wrapped around the discs. In a further modification dispensing with the gear segments 29 the rods 16, 24, Fig. 3, have a common pivot 34 on the member 21 and are coupled by links 36, 35, respectively, parallel to the rods. Means may be provided to reciprocate the bracket 26.

Abstract: 680,451. Materials for making coke. BURSTLEIN, W. M., and SOC. DES ACIERIES DE LONGWY. Nov. 8, 1949 [Dec. 27, 1948], No. 28622/49. Class 55 (ii) [Also in Group II] In the manufacture of metallurgical cokes from poorly coking coals, mineral and organic concentrates are formed and some at least of those rich in ashforming compounds or sulphur and phosphorus are removed. The vitrain concentrates are separated and the durain finely ground, a coking blend of the required petrographic composition being prepared by mixing predetermined proportions of other organic concentrates with the ground durain suitably adjusted as to size distribution. In a modification concentrates rich in vitrain and clarain are mixed and carbonized after removal of mineral constituents. Crushed coal or fines is subjected to separation on superposed vibrating screens a, b, c, d to obtain five graded fractions. The finest dust passing screen d and comprising fusain and oxidized coal is burnt in boiler furnaces C. Fraction c-d comprising vitrain and clarain is passed to a cleaner E<SP>3</SP> to remove sedimentary minerals and then to a coking oven F. Fraction b-c comprising vitrain, clarain and durain is similarly passed through cleaner E<SP>2</SP> and a mixer V, or it may be ground more finely in a mill B and passed through a final separating screen sf before being coked. Fractions a-b consisting of durain is passed through cleaner E<SP>1</SP> and then to mill B. The oversize of screen a comprising the natural conglomerate is shattered in a disintegrator D yielding on secondary screens e, f, g, h fractions treated similarly to those of the primary separation. The cleaners may comprise pneumatic tables or effect removal of shale &c. by dense or moving liquids. The middlings may be sent by a conveyer M to the boilers. In a modification each of the concentrates from the separator screens may be separately cleaned. An existing plant with two grinding mills may be adapted by one of the mills being operated at reduced speed to effect the disintegration, three separating stages with or without a cleaning stage being provided. Or a plant with a single separator and grinding mill may be utilised. Specification 665,313, [Group II], is referred to.
