Abstract: 683,092. Hay and corn harvesters. SPERRY CORPORATION. Nov. 2, 1950 .[Nov. 23, 1949], No. 26773/50. Class 6(iii) [Also in Group XXX] A machine for harvesting and chopping up forage crops, such as hay, maize, and sugar cane, comprises a frame 25 extending forwardly from a wheeled chassis about a transverse pivot axis 29 and carrying a conveyer 6 feeding to a comminuting unit 2, the frame being adapted to support a different harvesting unit for each crop so that each unit co-operates with the conveyer. The comminuting unit is conventional and is fed by a conveyer 6<SP>1</SP> which co-operates with the conveyer 6. A transverse shaft 15, journalled on the chassis, has integral arms 18, 19 pivotally supporting a frame 20 coupled to the frame 25 by links 32, 33. Further integral arms 16, 17 are connected respectively to a lifting cable 35 and to a counter-balancing spring 38. The cable is connected to a hand-lever 36, on the drawbar 4, for lifting the frame 20 and thereby the conveyer 6. In use, the conveyer is floatingly supported by the spring 38 with its lower end adjacent to the ground. For harvesting hay, a tined pick-up roller 41 is driven from the lower axle 64 of the conveyer 6, the tines being retractable during rotation. A paddle-roller 42 passes the hay on to the conveyer 6 where it is contained laterally by side screens 43, 44. The maize-harvesting attachment, Fig. 9, includes co-operating pairs of chain-conveyers A and B which travel at the same speed but diverge during upward movement so that the maize stalks are presented to the comminuter with the .butt-ends foremost. The conveyers A and B are also driven from the axle 64 by bevel wheels 65<SP>1</SP> and a shaft 66<SP>1</SP>. The comminuter and conveyer 6 are driven in series by a motor mounted on the chassis, Fig. 10 (not shown).

Patent GB-600746-A (GB)
Title: Improvements in or relating to calculating machines
IPC: G06C7/06
Filed: 1945-10-15
Abstract: 600,746. Cash registers. ALLEN-WALES ADDING MACHINE CORPORATION. Oct. 15, 1945, No. 26943. Convention date, Feb. 20, 1942. [Class 106 (i)] The mainshaft of a cash register is locked if no key in a special bank is depressed or if any of the keys are only half-depressed. As applied to a machine of the Wales type, when an entry is made on the keyboard properly, the mainshaft 1 is moved by a motor or by a crank 1a from the angular position A counterclockwise to position B, Fig. 5. A roller 11 on a full-stroke sector 2 releases a key-release lever 14 and an interlock lever 5 which move under spring action to their broken-line positions, the lever 14 withdrawing from the path of a latching bar 18, Fig. 10, which moves under spring action leftwards, and the tail 22 of the lever 5 descending to meet the zone 21 of the bar 18. The bar 18 rocks the usual locking strips 26, one to each row of keys, which engage above or below lugs 25 on the key stems according to whether the related keys are depressed or not. Depression of a key 24 in the special enforced designation group rocks a stop member 34 clockwise out of the path of a tongue 33 of a lever 29 pivoted at 30 and engaging a locking strip 26. The bar 18 is thus free to move to the left and the mainshaft 1 is free to move to position B from which it can be returned to position. A, the lever 14 restoring the bar 18 to its rightmost position. Entry into the totalizer and printing take place in known manner. A half-depression of any key 23 or 24 causes the abutment of its associated locking strip 26 against the key lug 25 and the bar 18 is prevented from moving to the left, whereupon the tail 22 of the lever 5 engages the zone 20 of the bar 18; preventing a nose 10 of the lever 5 withdrawing from engagement with a stop block 3 to limit the movement of the main shaft. If no key 24 is depressed, the related stop member 34 abuts the tongue 33 of the lever 29 and prevents movement of the bar 18 with a like result. More than one enforced designation group may be provided.

Title: Improvements in and connected with the filtration and clarification of water
IPC: C02F1/52
Filed: 1931-09-28
Abstract: 385,679. Purifying water ; filters. FILTRATION & WATER SOFTENING PROPRIETARY, Ltd., 395, Collins Street, Melbourne, Australia. Sept. 28, 1931, No. 26986. Convention date, Sept. 29, 1930. [Class 46.] Water which has been treated with coagulants, which render it acid, is subsequently, either before or after the removal of the coagulated impurities, brought into contact with alkaline material which is substantially insoluble in neutral water but soluble in acid water. Alums, aluminium sulphates, aluminoferric, ferrous and ferric sulphates and ferric chloride are mentioned as coagulants which render the water acid. Suitable alkaline materials are limestone, magnesite, dolomite, marble chips, burnt magnesite, alkali and alkaline earth silicates and calcium aluminate slags. When alkali silicates are used gelatinous silicic acid is formed which may be carried forward by the water under treatment to form a film on a filter through which the water is subsequently passed. An ammonium salt, such as the sulphate or chloride, may be added to the water between the treatment with coagulant and that with the alkaline material. Water may be passed upward in a casing 10, Fig. 1, from perforated pipes 15, through granular alkaline material 18 supported on a layer of gravel 17. Sand or other abrasive material may be mixed with the alkaline material. The velocity of the water is preferably sufficient to keep the alkaline material in partial suspension. Air may be admitted through pipes 20, 21 to assist in this and to aerate the liquid. To remove impurities which collect in the chambers the water therein is drawn off from below at intervals. The bed of alkaline material may be provided with mechanical agitating means. Fig. 3 shows apparatus in which a central core 25 and an annular column 26 of alkaline material are supported between plates 23, 24 in a casing 10, so that water flowing upwardly through the annular spaces 27, 28 comes into contact with their surfaces. The spaces 27, 28 preferably contain abrasive material. A byepass 29 and control valves 30, 31 permit of a regulated proportion only of the water being passed through the casing 10 and the remainder direct to a filter 121.

Abstract: 1509261 Positioning control system JAGENBERG-WERKE AG 27 June 1975 [11 July 1974] 27244/75 Heading G3N The mutual spacing of a row of cutting elements, e.g. pairs of circular cutters for slitting web material, is adjusted. Each pair of cutters has an associated stepping motor 1, 2, 3, each motor having the same speed and increment, and two limit switches 12, 13, 14, one limit switch sensing the rotation direction and the other sensing the zero position. The cutters are guided by carriages on rails and clamped on the rails during cutting. To change position, the cutters are rigidly interconnected and released on their rail using control box 4. Boxes 5-7 serve for other control functions, box 8 serves for repositioning, and the motors are controlled via computers 9-11 for the individual stepping motors. Boxes 15-17 have lamps for zero positions and push buttons for right or left steps. To reposition the cutting elements, box 8 is activated and the motors all travel leftwards at the same speed till motor 1 reaches its zero position when it moves to the right, its steps then being counted. When motor 2 reaches motor 1, the motor 2 then reverses and travels to the right. Similarly motor 3 moves right when it reaches motor 2. Alternatively the elements can be moved directly to their desired positions.

Title: Improvements relating to wing flaps of aircraft
IPC: B64C21/02
Filed: 1938-09-21
Abstract: 521,190. Controlling aircraft. BLACKBURN AIRCRAFT, Ltd., amd STIEGER, H. J. Sept. 21, 1938, No. 27565. [Class 4] An aircraft wing has a flap, the chord of which is large relative to the chord of the wing as a whole (e.g. 40 per cent. to 60 per cent.) when the flap is in neutral position, mounted for movement about an axis below the flap and behind its leading 'edge or otherwise movable downwardly and rearwardly to open a slot between the trailing edge of the final part of the wing and the leading edge of the flap. The outer ends of the flaps may be used as ailerons. Fig. 2 shows a flap 3 pivoted about a fixed axis 4 and tiltable into any of the positions shown, the flap acting as an air brake when in the upwardly tilted position. The lower edge 7a of the fixed part of the wing acts as an air seal for small downward angles of deflection, after which a convergent slot is opened. Fig. 3 shows a modification in which a fixed slat 8 on the flap divides the slot into separate passages. In this case the lower entrance to the slot is closed when the flap is in neutral position by a projection 10 on the fixed part of the wing. Other forms are described in which fixed slats on the flaps contact with the wing and form continuations of the upper surface as the flap is downwardly deflected. The parts used as ailerons in a form similar to that shown in Fig. 2 have the leading parts of the undersurface cut away to delay the entry of the leading edge into the airstream as the aileron is upwardly tilted. The trim of the craft is preserved, as the centre of pressure moves backwards, by the reaction of the deflected airstream upon the tail planes. The fixed slat 8 may be replaced by one connected by links to the trailing edge of the fixed wing or to the leading edge of the flap so as to open to the desired extent as the flap approaches its fully-down position. This applies also to the other fixed slats described. In another form a closure for the lower entrance to the slot may be withdrawable into the wing or be angularly movable or resilient to permit the flap to be upwardly tilted.
