Title: Improvements in or relating to potato and like planting machines
IPC: A01C9/00
Filed: 1933-07-11
Abstract: 422,356. Planting-machines. FERGUSON, C. S. R., 119, Dudley Road, Whalley Range, Manchester. July 11, 1933, No. 19587. [Class 6 (i)] A machine for planting potatoes &c. comprises a wheeled frame carrying a container having a rotary floor to arrange the tubers in line and deliver them through one or more outlets each leading to an oscillating or other conveyer along which the tubers are fed to a pivotally movable trap which delivers them into separate pockets in a rotary wheel or moving conveyer leading to the ground. The main wheels of the machine may be laterally adjustable and may have V-shaped rims to run on ridges. A shaft 10 driven from the wheels by chain gearing is mounted on a fixed support or table 11 and is geared by a chain 14 to another shaft 16 connected by bevel gearing with a tubular spindle 19 carrying a circular tray or table 20 on which is mounted the conical bottom 22 of a hopper or container 21. The rotary bottom 22 passes the potatoes singly through an aperture 26 in the lower cylindrical part of the container and they fall down the outwardly flared part 27 of the hopper on to a tray 28 revolving with the bottom 22. The inclined floor of the tray 28 is corrugated and delivers the potatoes singly to inclined shoots 31 in compartments on the tray 20. The shoots 31 are oscillated by the engagement of spring-controlled rods 37 with a pivoted tongue 54 adjustably mounted on a stationary carrier 48, the tongue bearing against a spring-controlled plunger 50 engaging the serrated periphery of a rotary block 52 attached to the tray 20. Linked to the ends of the rods 37 are flaps or traps 42 pivoted on the shoots 31 and having raised parts 44 against which the potatoes come to rest. The traps deliver the potatoes on to pivoted cups 45 which, as they are carried round, are moved by engagement with rotatable cams 55 so as to discharge the potatoes into the buckets 56 of an endless conveyer 57 leading down to the furrow. The wheel carrying the lower end of the conveyer 57 is carried by a pivoted part supporting a plough for making the furrow. This pivoted part may be raised by a lever, and furrow-closing discs may also be raised by the same lever. The apertures 26, 30 in the hopper may be closed by a door 72 moved by means of a lever 73. The tongue 54 and carrier 48 may be dispensed with and the rods 37 actuated by a cam. Two or more conveyers 57 may be provided. Stationary conveyers may be employed. Fertilizer from a hopper may flow on to the pockets of the conveyer or down a pipe to the furrow.

Title: Improvements relating to articulated stands with locking means
IPC: F16M11/12
Filed: 1954-07-05
Abstract: 751,823. Adjustable brackets. WAIBEL, E. July 5, 1954 [July 8, 1953], No. 19639/54. Class 52(5). An articulated stand for laboratory equipment, camera, electric lamp or other device has a vertical column 1 on which is rotatably mounted a sleeve 4 carrying a spindle 7 on which rotates a holder 5 carrying a bevel gear 6 which can be urged by a cam 8 against a spring 10 to engage bevel gears 2, 3 fixed to the column 1 and thus prevent rotation about either axis. In a modification, Fig. 2, a holder 14 is carried on a stirrup 15 on a spindle 16 rotatably mounted in a column 12, spur wheels 18, 19 engaging a rim gear 13 on the column. A spring-urged lever 20 engages the teeth of wheel 18 to lock the assembly. In another modification the legs of the stirrup are resilient and are urged together by a cam to lock the assembly, gears, 13, 18, 19 being replaced by bevel gears. In other modifications the rotatable pinions have two sets of teeth, one set engaged by spring- urged levers to lock the assembly and the holder carries the article through a third articulation which can be locked with the others, a single button 37, Fig. 5, operating both locking mechanisms. In a further modification, Fig. 7, the stirrup arms carry half spindles 16 with extensions 16<SP>1</SP> bearing against a truncated cone 39 integral with column 40, the spindles carrying truncated cone members 41, 42 disposed inside an envelope 45 which is vertically movable. Actuation of a nut 46 moves the envelope against spring 48, downward movement of the envelope causing members 41, 42 to be pushed outwardly and be wedged in the end portions of envelope 46 to lock the assembly by friction.

Title: Manufacture of 2,2,3,3-tetrachloro-1,4-butanediol
IPC: C07C31/34
Filed: 1957-06-24
Abstract: The invention comprises 1 : 4-diacyloxy-2 : 2 : 3 : 3 :-tetrachlorobutanes and a process for the preparation of 2 : 2 : 3 : 3-tetrachlorobutane-1 : 4 -diol by treating 2-butyne-1 : 4-diol with an acylating agent under esterifying conditions to produce a 1 : 4-diacyloxy-2-butyne, treating this with sufficient chlorine to produce a 1 : 4-diacyloxy-2 : 2 : 3 : 3-tetrachlorobutane and hydrolysing this to give the desired product.  The three steps of the process may be carried out consecutively in the same vessel or the process may start at the second step.  The esterification step may be carried out using a carboxylic acid, acid chloride or acid anhydride and formic, acetic, propionic lauric, stearic, palmitic, benzoic, naphthoic, 0-, m-and p-methylbenzoic, phenylacetic, phenylpropionic, furoic and nicotinic acids are mentioned.  The reaction is preferably carried out in the presence of an inert solvent such as benzene, toluene, chlorobenzene or dichlorobenzene and an esterification catalyst such as p-toluenesulphonic, benzene sulphonic, sulphuric or hydrochloric acids.  The chlorination step is carried out with molecular chlorine in an organic diluent of the type used in the esterification and the product is hydrolysed by heating with dilute acid, e.g. sulphuric or hydrochloric acid.  The product may be isolated at any point in the process.  In examples 2-butyne-1, 4-diol is esterified with acetic anhydride, lauric acid, benzoic acid and furoic acid and the resulting diesters are chlorinated to the corresponding tetrachloro derivative and then hydrolysed to the tetrachlorodiol.  Specification 803,058 is referred to.

Title: Improvements in or relating to permanent magnets
IPC: H01F13/00
Filed: 1950-08-10
Abstract: 668,057. Permanent magnets. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 10, 1950 [July 4, 1950], No. 19918/50. Class 35. A unitary anisotropic permanent magnet unit has a series of poles whose length is great compared with their spacing, and the magnetic preferential direction of the entire body is parallel to the direction of the pole limbs. The invention is shown in a straight pole unit, e.g. for magnetic separators, but annular pole-members in which the poles are radial or axial, e.g. for cycle dynamos, are also described. The magnet body is hardened in the direction 11 between magnetic poles 9, 10. It is stated that although the flux 3 in the transverse connection between the poles is at right angles to the magnetic preferential direction, the reluctance is not substantial, probably due to flux scatter, as shown at 12. The connecting yoke part is made thicker than is theoretically necessary such that the excess material used is not greater than 30 per cent of the volume of a pair of poles. Final magnetization is effected by turns of wire round the individual poles.

Title: Method of obtaining construction materials for roads embedded in an organic binder
IPC: E01C7/18
Filed: 1937-07-24
Abstract: Separating or filling material, e.g. powdered tale, stone or coal, is applied to road making material comprising stone or like fragments coated with an organic binder such as bitumen tar &c., to render it capable of being stored and transported without agglomerating, by treating the coated stone &c. with a suspension of a filler in water or other liquid which is substantially a non-solvent for the binder and the filler, whereby a layer of separating material is deposited on each fragment.  The suspension is suitably of 5-15 per cent concentration.  The stone after being coated either by hot molten bitumen or by an aqueous emulsion may be fed directly to the separating bath, removed and dried.  When coated by a hot treatment, it may retain sufficient heat to effect the drying.
