Title: Improvements in or relating to Tilling Apparatus.
Inventor: TONY BALLU
IPC: A01B3/56
Filed: 1918-09-04
Abstract: 119,034. Ballu, T. Sept. 13, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Power cultivation of land; motor implements; ploughs; adjusting parts of implements; frames. -A motor tilling-implement comprises a selfcontained chassis 1 supported on driving wheels 2, 3 and steering wheels 4, 5, which carries a symmetrical frame 11, 12 on which are mounted implements adapted for one-way tilling, the frame 11, 12 however being capable of division so that one set of tools may be removed, the other set then being used as in an ordinary tilling- machine. In the form shown, ploughs are clamped between two superposed plates 9 carried at the ends of the frames 11, 12, these plates being held together by bolts whereby the distance between them can be varied and ploughs removed or added. When the number of ploughs is increased the bar 12 of the main frame may be turned to the position shown in dotted lines in Fig. 2. The bars 11, 12 are provided with slots through which pass pins 13 projecting from the lower ends of vertical rods 15 supported by, and vertically adjustable relatively to, the chassis 1. The slots in the bars 11, 12 form an anti-balance device for the implement, the traction of the ploughs being effected through chains 23 attached to the axle of the driving wheels and to the plates 9. Stops 41 may limit the movement of the pins 13. The swing- ing of the ploughs at the headlands is accomplished by the winding of a cable 26 about a winch 24 around a pulley on which a belt 28 driven from a countershaft of the motor, loosely passes. The belt 28 may be tightened to cause the winch to be operated by pressing on a hand-lever 35 carrying two belt-engaging rolls 33, 34. The winch is locked in position by a pawl. To permit the removal of the tools at one side of the machine, the bars 11, 12 are made so that they can be divided into halves at their central link, which is made of double thickness for connecting the two halves together. The implement is moved either by towing cables passing round the drums 40 or by the direct tractive effect of the driving wheels.

Abstract: 1,224,115. Phosphating ferrous metal. AMCHEM PRODUCTS INC. March 19, 1969 [March 19, 1968], No.14418/69. Heading C7U. In a process of forming a phosphate conversion coating by the reverse roller coating technique on a moving ferrous surface by applying an acidic aqueous chlorate-accelerated "non-coating" phosphate coating solution thereto by means of a contrarotating roller whose surface is moving in a direction opposite to the direction of motion of the ferrous surface, the coating solution employed contains at least 5 grams of phosphate ion derived from phosphoric acid and/or alkali metal and/or ammonium phosphate(s) and/or monohydrogen and/or dihydrogen phosphate(s) per litre, and at least 3 grams of chlorate ion per litre, said solution having a pH within the range 1 to 3.5, so related to the concentrations of phosphate and chlorate in the solution as to form said conversion coating on said surface within a dwell time of up to half a minute, and excess coating solution is subsequently removed from the surface. The chlorate ion is provided by Na, K, or NH 4  chlorate, and the pH may be lowered or raised as necessary, the former by HC1, H 2 SO 4 , or HNO 3 ; the latter by soda-ash. The upper prefered limits for phosphate and chlorate are 20 g/1 and 12.5 g/l respectively, and surfactants may be added to the solution. Prior to coating, the metal may be heated, as by hot-water spraying, to 130-140‹F. After coating, the metal may be given a chromium-containing rinse. In the figure, strip S is coated on the upper face by liquid 3 and on the lower face by liquid 13, the rollers and strip moving as shown, and excess coating liquid is removed as by rollers 29, 30, into pan P.

Title: Improvements in automatic landing brakes for aeroplanes
IPC: B64C25/44
Filed: 1928-05-16
Abstract: 290,673. Soc. Anon. des Ateliers d'Aviation L. BrÚguÚt. May 19, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Applied by springs.- The wheel brakes of an aeroplane are applied in accordance with the pressure on the tail skid, and the braking pressure may also be influenced by the load on the wheels, in order to prevent them from skidding, or by the differential pressure on the wheels, to correct a swerve, or by both. In the simplest form of the apparatus the pressure on the tail skid tensions a spring which applies the brakes to the wheels, a device for lengthening or shortening the transmission enabling the pilot to release or reapply the brakes when required. By using band brakes passing over drums on the wheels which can move upwardly under load the braking pressure is varied with the load. Fig. 3 shows a brake 18 which is normally held off by a spring 31 but when the spring 31 is extended by pressure on the tail skid a spring 20 applies the brake. The pressure of the spring 20 is regulated by a nut 21 having a pinion 28 engaging a rack 29 on the axle guide so that as the axle rises the spring 20 is compressed. Fig. 7 shows brakes applied by springs similar to the spring 20 of Fig. 3, but as the wheels rise under load any unequal pressure causes a differential tensioning of two springs 40, 40<a> and a rod 37 is displaced to -compress one actuating spring and slacken the other by pressing against plates 35, 35<a>. To make the brake pressure also dependent on the total load in this form of apparatus the plates 35, 35<a> are connected to the ends of the rod 37 by inclined links.

Title: Improvements relating to the handling of plastic sheets and to apparatus for use in moving material in sheet form
IPC: B65G57/04
Filed: 1945-06-08
Abstract: 621,111. Stacking sheets. TURNERS ASBESTOS CEMENT CO., Ltd., and ROOKSBY, W. H. June 8, 1945, No. 14589. [Classes 100 (i) and 100 (ii)] [Also in Group XXX] An apparatus for forming a stack of sheets comprises a suction box 2 mounted to swing from a frame 3 which is itself mounted to rock about a horizontal axis 4 and serves to move the suction box from one side of the axis to the other, and means, e.g. levers 30, 31 by which the box is constrained to travel in a vertical path as it places a sheet on the stack, whereby the stack is built vertically. In the Figures suction box 2 is suspended freely from radial arms 17 (which are keyed to hollow rods 16) by cross-arms 18 and posts 23, the latter passing freely through blocks in the cross-arms so that the lost-motion permits the box to stack sheets as the pile grows higher. Rod 16 is journalled into frame-arms 14 keyed to shaft 4 and is fixed to links 30 which are pivoted to and guided by links 31 slotted at 32 so that links 31 may turn and slide about shaft 4 and, by means of rollers 33 rolling round cams 36, may constrain the box to move in a vertical path during the lower portion of its travel. Driving motor 40 also drives traveller 47 backwards and forwards on the threaded rod 48 between reversing switches 45, 44 (Fig. 3), so that the frame arms automatically swing over from side-to-side and back again. Switch 46 is actuated on the return swing of the apparatus and serves to bring the arms to rest near the vertical after each set of movements, before the motor is started again by a main switch. Suction is introduced to box 2 through pipe 13 and hollow rod 16 and is controlled by valves 80, 81 in pipes 82, 86 leading to suction and open-air respectively. The valves are shown in normal position to admit to the air but upon actuation of switch 44 solenoid 90 is energized to displace valve rod 89 and admit suction, so that the suction box seizes an asbestos sheet at the end of one swing and is caused by actuation of switch 45 to deposit it at the end of the next swing and then to return empty for the next sheet. Two such apparatus may be worked side-by-side so as to form an alternate pile of asbestos sheets and templates. The suction box may be pierced with holes at the bottom and covered with gauze and also with hessian, or may be open at the bottom and its periphery rimmed by rubber. The underside may correspond to any corrugated or other shaped sheet. The main switch may be manually or automatically operated by the passage of sheets along the supplying conveyer shown as in Specification 621,136, [Group XXX].
