Title: Packaging machine for loading trays with articles
IPC: B65B5/06
Filed: 1975-07-18
Abstract: 1504711 Loading articles in trays; conveyers THURNE ENG CO Ltd 12 July 1976 [18 July 1975] 30286/75 Headings B8C and B8A A packaging machine for loading trays 8 with articles 1 comprises a conveyer 3 for feeding the articles 1 on to a pivotal plate 22 above which is mounted a stop 23 for locating articles on the plate 22 and a pusher 24, 25, the machine further including a mechanism, Fig. 4 (not shown), for moving the plate 22, the stop 23 and the pusher 24, 25 so that the plate 22 is tipped, the stop 23 is moved away from an article or articles on the plate and the pusher 24, 25 is moved to push the article or articles into a tray 8 located beneath the plate 22 on a conveyer 13. In operation the edge 26 of the plate 22 obstructs the passage of articles on to the plate 22 when the latter is in its tipped position. The conveyer 3 for the articles 1 and the conveyer 13 for the trays may move intermittently or continuously. The plate, stop and pusher moving mechanism is driven from the drive of the tray conveyer 13 and may include an over-ride control preventing movement of the plate, stop and pusher when a required number of articles is not present on the plate or when there is no tray located beneath the plate. Two of the above described machines 6, 6a may load trays conveyed by the conveyer 13 which is common to both machines. In such an arrangement the mechanisms of the two machines may be arranged so that either each tray receives a layer of articles from each of the machines or alternate trays receive a layer of articles from one of the machines and the intervening trays receive a layer of articles from the other machine. In the arrangement of two machines 6, 6a illustrated in Fig. 1, articles 1 are fed on to two conveyers 3 and 4, each of which has guides 5 for separating the articles into streams. The trays 8 are deposited from a stack 9, by a depositor 7, on to a conveyer 10 which includes a series of transverse flights 11 and a guide 12 for moving the trays transversely across the conveyer 10. The conveyer 13 which receives trays from the conveyer 10 is similar in construction to the conveyer 10 and delivers the filled trays on to a dead plate 15 from which they are moved on to a conveyer 16 which feeds a transfer unit 17. The trays are subsequently conveyed by a conveyer 21 from which they are taken to a shrink wrapping machine.

Title: Apparatus for detecting faulty synthetic filaments during the spinning process
IPC: D01D5/00
Filed: 1961-08-23
Abstract: 997,194. Faulty filament detecting device. FARBWERKE HOECHST A.G. Aug. 23, 1961 [Aug. 23, 19601, No. 30448/61. Heading B5B. [Also in Division H2] Apparatus for detecting thickenings in synthetic filaments during spinning comprises a movable feeler movable by thickenings in one or more travelling filaments against which the feeler rests, and electrical contact means operate by the said movement of the feeler to operate indicating and recording means. A resilient connection may be provided between the feeler and the electrical contact means, permitting the feeler to move beyond the position at which it operates the electrical contact means, which may be a contact arm movable by the feeler into contact with a fixed contact. The fixed contact is preferably adjustable so as to vary the extent of movement of of the feeler required to close the electrical contacts. The feeler may be a longitudinally rotatable and eccentrically mounted rod, balanced by a counter-weight, and resting against the filament or filaments travelling on the surface of a fixed rod. Desirably, the rotatable rod is resiliently urged towards the fixed rod by a spring. As shown, a casing 1 supports a fixed rod 2, on which the moving filament rests, in contact with the rod 3 which is fixed eccentrically to shaft 4. The rod 3 can be balanced in any position by a counterweight 5 adjustable radially about the shaft 4. A spiral spring 6 fixed at one end to the casing 1 and at the other to the shaft 4 urges rod 3 into its position of rest in contact with rod 2. A contact arm 7 is rotatably mounted on the shaft 4 but is held in position by a spring 8. A coacting contact 9 is adjustably fixed to the as ing 1 in the path of contact arm 7. By adjusting the fixed contact 9 the extent of movement of the feeler required to close the electrical contacts can be varied. When a thickening of the filaments passing between rods 2 and 3 pushes aside the rod 3, the shaft 4 rotates and the spring 8 pulls the contact arm 7 against a stop 11 on an arm 10 rigidly fixed to the shaft 4. Owing to the spring 8 connecting 7 and 10 the shaft 4 can rotate beyond the position at which contact arm 7 meets contact 9 (see Fig. 3), should a large thickening of the filaments occur, and the gap between rods 2 and 3 can open further. In this way thickenings can pass through the gap which are considerably larger than those of the minimum size for the detection of which the apparatus can be adjusted. The making of the electrical contact is utilized in a switching device of known type to produce the control voltage of a thermionic valve, which transmits the current and actuates a signalling device and a counting mechanism.

Filed: 1938-10-21
Abstract: 519,394. Tractor-drawn agricultural implements. BROWN & SONS (HUDDERSFIELD), Ltd., D., BROWN, D., and SYKES, A. Oct. 21, 1938, No. 30469. [Class 6 (i)] In a tractor-drawn agricultural implement, the depth of cut is controlled by a variable delivery pump which is regulated by the variations in the pull of the tractor or in the position of a ground-surface member relatively to the implement tool. The pump delivers to a ram which adjusts the depth of cut. A driven shaft a carries an eccentric b within another eccentric c surrounded by the strap (not shown) of a connecting rod for operating the pump. The eccentric b carries a pin b' on which is pivoted an arm d which is held by a spring e against an abutment c<1> on the cam c. A tapered boss f slides on the shaft a under control of a fork g on a rod h which moves either in accordance with the pull exerted by the tractor or with the position of a groundsurface member relatively to the implement tool, so that the eccentricity of the eccentric c is correspondingly varied. In a modification, the pump is driven by a crank of constant radius which oscillates a pivoted rod of variable length, an intermediate point in the rod being connected to the pump rod. In another modification, the crank pin may work in an angularly adjustable guide and be connected through a link to the pump plunger. The guide is adjusted by the tractor pull or the position of a groundsurface member. The pump delivery is normally that necessary to hold the ram in the predetermined position and is varied when necessary to restore the ram to that position.

Title: Improvements in methods of reducing metals and making alloys
IPC: C21C7/00
Filed: 1922-11-09
Abstract: 198,323. Hamilton, W. B., and Evans, T. A. May 23, 1922, [Convention date]. Metals and alloys. - A method of reducing metals and of forming alloys comprises the formation of a bath of molten metal in a furnace, the formation of a layer of slag thereon, and the addition to the slag of ore containing the oxide or other reducible compound of a metal and an exothermic reducing-agent such as aluminium, silicon or magnesium, whereupon the metal of the ore is reduced and passes into the molten bath. The process is applicable : (1) to the production of products other than iron-chromium alloys using aluminium as the reducing-agent; (2) to the production of iron-chromium alloys or other alloys or products using silicon, ferro-silicon, calcium silicon, or magnesium; (3) to the reduction of compounds such as chlorides and fluorides; and is distinguished from the process described in Specification 174,271 for the production of ironchromium alloys using aluminium as a reducing- agent. The production of alloys of iron with chromium, tungsten, nickel, manganese, or other metals, and of alloys of copper with aluminium or tin, is referred to. In the case of ironchromium alloys the slag may be formed from a mixture of limestone, mill-scale and fluorspar, and the molten bath from iron scrap or ferro-chrome. A single metal may be obtained by treating an ore consisting substantially of only one metal oxide and using a molten bath of the same metal. Heating may be continued for a short time after the reaction is complete to effect refining of the metal or alloy.
