Filed: 1942-08-14
Abstract: 559,651. Root-crop harvesters. SHEPHERD, A. Aug. 14, 1942, No. 11374. [Class 6 (iii)] A machine for. harvesting root crops, particularly turnips, comprises a frame mounted on a single wheel I and carrying a topping mechanism Y guided by a member S, an inclined plate R for directing the roots against a tailing knife 1 and a horizontal roller, or belt, conveyer 13 for conveying the roots to a pair of inclined conveyer belts H from which the roots, assisted by a cleaning drum 14 with a helical blade 14a, pass to a lateral-delivery belt conveyer 15. A pivoted stop 16 is provided for regulating the point of delivery so that roots from several drills can be deposited.in a single row or the delivery side may be supported by a vehicle being loaded. The driving roller P of the belts H and the drum 14 are driven through gears N, O, J from the wheel I and the driving roller 21 of the belt 15 through skew gearing 22. The rollers 13 are driven by a chain 20 and sprockets from the roller G<SP>1</SP> of a belt H and a roller 38 through bevel gearing. The member 5 is carried by a cranked drop arm T, mounted in brackets U and having a squared portion 35 engaging a Y-shaped spring 34, so that it rides along the right-hand side of the roots in a drill and the topper Y is pivoted on a rod X carrying a spring 6 for holding the fixed knife Y' against the arm T so that it follows the member S. The movable knife Y<SP>2</SP> of the topper, Fig. 3, is closed on the knife Y<SP>1</SP> against the action of a spring 25 by a fixed cam 28 pressing cam followers 32 on a rotating plate 31 against a friction lining 27 of a collar 26 secured to the knife Y<SP>2</SP>. The topper is adjustable vertically by means of a handle 5 connected by a cable 4 to a lever 2 linked to a collar 18, resiliently mounted on the rotatable sleeve 3 and carrying the bracket for the topper. The tailing knife 1 is adjustable vertically through the cranked end of a connecting- rod 8, a link 9 and spring-pressed friction discs 11 from a handle 10. A sole plate 37 is provided.

Abstract: 907,881. Delivering measured quantities of liquids. WARD, L. T. April 3, 1959 [April 10, 1958; Sept. 24, 1958], No. 11448/59. Addition to 798,683. Class 106 (5). [Also in Group XXVIII]  A valve for dispensing a measured quantity of liquid from a pressurized container 10 comprises a measuring chamber 14 normally communicating with the interior of the container through an inlet aperture and a valve plunger 21 which, when depressed, connects the chamber 14 to a spray nozzle 35 through a port 20 and closes the inlet aperture, the latter being formed as a valve comprising a tubular resilient element 25 in sealing contact with the inlet aperture and a portion 23c on the plunger of greater diameter than at least part of the bore of the element 25; the part of the valve housing 13 surrounding the element 25 has an inner diameter greater than the outer diameter of the sealing portion 27 of the element 25 so that the latter is free to expand when the portion 23c of the valve enters it. The plunger may seal on a necked, reduced-bore portion 27 of the element and may itself have a necked portion 23b so that the container can be filled by replacing the spray head 31 with a filling head and depressing the plunger beyond the normal sealing position. Curved channels 24 prevent trapping of liquid disposed above the portion 27. The element 25 may be a separate element or part of the dip tube 25y. Modified forms of the element comprise a top-hot section with an aperture in the crown and a cup-shaped form 61, as shown in Fig. 7, which expands into the sealing bevel 47 provided on the walls of the measuring chamber.

Abstract: 893,956. Purifying gases. CLAYTON SON & CO. Ltd. April 15, 1958, No. 11884/58. Class 55 (2). Hydrogen sulphide is removed from fuel gases by saturating the gases with moisture at a temperature of 50‹ C. to 100‹ C. in a humidifier 5 and using them to fluidize a bed 3 of iron oxide or other purification material in a reaction vessel 1, the temperature being maintained between 50‹ and 100‹ C. by means of a heating or cooling element 6. The gases may be passed through cyclone separators 7, 7a to a similar reaction vessel, the gases finally passing through pipe 9 to a wet dust extractor and storage. The purification material may be revivified by air or oxygen admitted through line 11 and valves 11a. Fresh material may be passed from hopper 12 into the second reaction vessel 1, or last one in the case of a series of such vessels, and material passed from the vessel to a chamber 15 and thence through an ejector 14, supplied with purified gas or air, to a cyclone separator 17 and the previous reaction vessel. Gas or air from the separator 17 is returned to the last vessel 1. In a modification the purification material is transferred to a separate vessel in which revivification takes place with the admission of air, and is then passed back to the reaction vessel.

Abstract: 255,419. Automatische Fernsprech- Anlagen-Bau-Ges. July 20, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Order apparatus.-Lamps for indicating successively dialled digits are lit in turn as each digit is completed and remain lighted until the whole number is shown. The circuit illustrated is for enabling a telephone operator to check the number she sends. A key Tv is pressed at the commencement of sending to energize a relay C, and a contact i is closed at each impulse and a contact o throughout each digit. Relay C energizes relays H, G and magnet DS, which steps the switch S<1>, S<11> to its second position and short-circuits relay H, and G, DS also become de-energized. At the commencement of the first digit, relay B re-energizes H over the off-normal arc S", and the impulses are repeated over a, S<1> to the magnet Dr1 of the first register DW1, the relay P being energized also by the first impulse and locking itself. At the termination of the first digit the relapse of relay B energizes G over h1, b, h3, S". The switch S<1>, S" takes a second step, the relays H, G and magnet DS are de-energized as before, and the first-digit lamp is lit over q2, h2, c1. The second digit is similarly recorded on the register DW2, the relay Q being energized at the first impulse to keep the first-digit lamp burning and the second-digit lamp being lit as soon as the digit is finished, and so on. At the termination of the final digit the switch S<1>, S<11> steps to its normal position, and the key Tv is released to unlock relays P, Q &c. which close circuits for restoring the registers.
