Title: Improvements relating to machines for digging and riddling root crops, more especially potatoes
IPC: A01D17/10
Filed: 1949-03-14
Abstract: 664,522. Root-crop harvesters. TIMMIS, J. April 24, 1950 [March 14, 1949], No.. 6854/49 Class 6(iii) A root-crop harvester comprises a share which penetrates the ground under the crop as the machine moves forwards and which guides the crop on to a plain imperforated elevator belt, the latter carrying the crop rearwardly and upwardly without riddling and delivering it to a separate riddle down which it moves by gravity. In the construction shown the frame 24 of the machine is fitted at the front with a draw-bar bracket 43, a pair of vertically adjustable wheels 41, and a pair of vertically and laterally adjustable ridge trimmers 39. The conveyer 31 is carried by rollers 32, 33, of which roller 32 is belt-driven from a pulley on a shaft 28 which is geared to the main axle 25. A rotary tinned member 35 breaks up any soil lifted with the crop and urges it rearwards on to the elevator. The riddle, the slope of which can be adjusted by mechanism connected to a handwheel 23; is composed of a number of bars 15, Fig. 3, each consisting of two rails 15a spaced apart by blocks 16, and a central rod 15c raised slightly with respect to the rails. There is very little clearance between adjacent bars. Eccentrics on shafts 17, which are driven from shaft 28, impart movements to the bars by engaging in holes in the blocks 16; the holes in the lower blocks are. slightly elongated so that only a rising and falling movement is imparted to the lower ends of the bars. The rails 15a are longer than the rods 15c to permit the haulms to discharge rearwards on to the ground while allowing the potatoes to fall into a hopper 11. The latter is tipped at intervals by a cam 13 driven from the ground wheels.

Abstract: 1535004 Extrusion WESTERN ELECTRIC CO Inc 18 Feb 1977 [8 March 1976] 06873/77 Heading B3P  A method of shaping an elongated workpiece or rod 17 comprises feeding the workpiece between a radially extending surface 13 of a rotor 11 and a co-operating driven moving surface 14 of a further rotor 12 such that pressure applied by the rotors 11, 12 is sufficient to transport the workpiece and force it against a deforming member or die 22 to produce continuous deformation of the workpiece. The rod 17 is coated with a viscous fluid, e.g. beeswax or polyethylene wax, and it is located in an annular groove 16 in the surface 13. The rotors 11, 12 are mounted eccentrically to each other and they are driven by fluid motors 57, 57 via meshing pinions and annular gears at slightly different speeds. The rotor 11 is tilted slightly relative to the rotor 12 and they are closest together where the greatest overlap occurs. The entry 68 to the die 22 is located at this point and the tangential speeds of the rotors are also substantially equal here. The rod 17 is extruded hydrostatically by means of the wax coating into a wire or wires 26, the extrudate being guided initially by a curved die stem 23. The rod may alternatively be extruded without wax or other lubricant in direct contact with the apparatus.

Title: An improved process of treating vegetable fibres
IPC: D06L4/10
Filed: 1930-03-03
Abstract: Natural impurities in cotton, linen, jute, &c., are removed by boiling the material in the presence of ordinary or true mahogany sulphonates.  The process may take place in aqueous solution at atmospheric pressure, the material being passed continuously through the solution.  With a solution containing 0,1 per cent to 2 per cent of sulphonate and 1 per cent sodium hydroxide, a boiling lasting 30 minutes suffices.  In an example, samples of duck &c. were boiled for an hour at atmospheric pressure in solutions containing from 0,25 per cent to 2 per cent of sodium hydroxide and the same proportions of sulphonates.  After rinsing they were immersed for a few minutes in a 2 DEG  Tw. bleaching powder solution and exposed to the air for an hour.  After rinsing and souring with 1 per cent hydrochloric acid they were rinsed and dried.  Specifications 247,940 and 252,051, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Improvements in or relating to contact converters
IPC: H02M7/40
Filed: 1955-03-10
Abstract: 769,362. Rectifying. SIEMENS-SCHUCKERTWERKE AKT.-GES. March 10, 1955 [March 10, 1954], No. 7108/55. 'Addition to 711,829. Class 38 (2). In a mechanical contact converter operating with circuit opening and circuit closing current steps produced by switching chokes having premagnetization comprising a constant component and a second component dependent upon the voltage across the switching choke during the current step as is disclosed in the parent Specification, 'the second component is divided into two portions. The first component has a value not substantially exceeding that of the static magnetization of the switching choke, the first portion of the second component is such that its resultant with the, first component is smaller than the main magnetization at the instant of contact closure, and the second portion which leads the supply voltage reduces the difference by said resultant and main magnetization. The switching choke 3,of each phase of a polyphase rectifier supplying a load. 5 has a winding 6 for. the constant premagnetization current and is tapped for the connection to it of the varying premagnetization circuits. The second component proportional to the switching choke voltage during the closing step is developed by rectifier 24 and resistor 23 connected in. series across rectifier contacts 4 and part of choke.3, and the third component is supplied from. an A.C. source through a transformer 37 having its secondary winding. connected in series with a rectifier. 25 and resistor. 38 across resistor 23. Transformer 37 is supplied with a voltage which is arranged to lead the main supply alternating voltage of the phase. The constant, component may be less than H 0  and of about the magnitude corresponding to the value of the magnetizing current, i c  when the switching choke voltage e D  is zero in 'the i c /e D  curve of the switching choke, Fig. 1, so that the constant component does not complete the closing stage before the contacts closing when this closing is retarded. The second component follows the chain-dotted line and the third component adds sufficient magnetization to bring the total for lower values of c D  to the solid straight line when continued back to the i c  axis. These two components are controlled by rectifier 24 to take effect just before contact closing. The invention is described as applied to a contact converter with contacts operated electromagnetically by an auxiliary winding as disclosed in Specification 716,905, Fig. 3 (not shown).
