Title: Automatic depth control for ground-working implements
IPC: A01B63/112
Filed: 1945-12-05
Abstract: 617,166. Agricultural implements. FERGUSON, Inc., H. Dec. 5, 1945. No. 32867. Convention date, Jan. 10, 1945. [Class 6 (i)] In an automatic depth control for tractor operated ground working implements of the type described in Specification 470,069, comprising a hydraulic unit for operating the implement, an upper and lower link means for carrying the implement, and means for controlling the power unit to maintain the implement at a predetermined depth, a balance means such as a spring 30 is adapted to resist either compressive or tensile force in the link means, for example an upper link 1 to enable effective depth control of the implement even at depths where the predominating force in the link means is that due to the overhanging implement weight. As shown a control rod 4, pivoted on a pin 2a on which pivots the upper link 1, is screwed into a sleeve 5 which is provided with grooves so that it may be locked on rod 4 by a pin 7. The sleeve 5 slides in a collar 8 which is adjustably screwed into a partition wall 9. The end of the rod 4 fits into a bore provided in the base of a yoke 13 which connects the rod to a valve operating lever 14. The spring 30 has at each end collars 33, 34 which are slidably mounted on rod 4. Collar 34 is contacted by abutment 34a on rod 4 and collar 33 is contacted by adjustable sleeve 5. Hence any draft load reacting as a compressive force through upper link 1 is communicated to control spring 30 through abutment 34a and collar 34. To operate the hydraulic system a. compressive force is necessary to operate lever 14 and when the draft load is so light, as when a cultivator is used that a force in tension is present in the upper link 1 due to the overhanging weight of the implement, the control spring is loaded and assists the draft load in balancing the overhanging implement weight.

Title: Improvements in the production of articles and structures
Inventor: JONES EDWARD RICHARD STANLEY
IPC: B29C65/00
Filed: 1955-11-21
Abstract: Articles and structures are produced by forming a thin coating of polythene on a metal surface, oxidizing this coating by baking it at a temperature above its melting-point, contacting the coating with molten high-density polythene, i.e. polythene of a density not less than 0.94 gm./cc., and causing or allowing the high-density polythene to solidify by cooling.  The initial coating may be applied by dipping the metal in a solution or gel of polythene, or spreading a gel on the surface; by dipping in a dispersion or in molten polythene; by coating the surface with polythene powder and fusing; by flame spraying; or by covering the surface with a pre-formed film of polythene which is subsequently melted.  Oxidation catalysts such as di-tert-butyl peroxide, tert-butyl hydroperoxide, ferric linoleate, cobalt naphthenate or zinc chloride may be added.  More than one coating may be applied and oxidized before the high-density polythene is applied.  The process may be applied to any metal, e.g. aluminium and steel, and forms a particularly good bond with copper; other metals or other materials may be copper plated before coating. The high-density polythene is applied by extrusion moulding, calendering, casting or like method.  The method may be applied to the production of electrical goods such as insulators, generator stators, condensers, plugs and sockets and valve bases and the like.ALSO:Articles and structures are produced by forming a thin coating of polythene on a metal surface, oxidising this coating by baking it at a temperature above its melting-point, contacting the coating with molten high density polythene, i.e. polythene of a density not less than 0,94 gm. cc., and causing or allowing the high density polythene to solidify by cooling.

Abstract: 408,552. Printing-machines. WULF. G., 10, Bonifatiusplatz, Hanover, Germany, Nov. 29, 1933, No. 33507. [Class 100 (ii).] Printing processes ; inking - apparatus.- Paper or textile strips are printed so as to obtain shaded coloured surfaces in a single operation by varying periodically the pressure between the rollers conveying colour to the strip in accordance with the movement of the strip a. The strip a is printed by a plain or patterned roller c co-operating with an impression roller b and receiving colour from a roller d in contact with an immersion roller e. The roller d is mounted in bearings g, and is pressed towards the roller c by a cam k which varies the pressure of the roller d on the roller c periodically and so produces shaded impressions. Instead of a cam k with a continuously changing contour, a cam k formed of four quadrants of circles with slightly differing radii may be used. In a further modification the roller d may be mounted in fixed bearings, and be formed of a number of eccentric portions d<1>, d<2>, d<3>, d<4>, Fig. 4, which are displaced axially with respect to each other. The rollers d may be mounted in rotatable eccentric bearings, and instead of varying the pressure between the rollers c, d, the variation may occur between the roller d and a further roller arranged between the rollers d and e. In this case the shading effect in the printed impression is less marked.

Title: Electric circuit breaker
IPC: H01H1/18
Filed: 1955-11-23
Abstract: 812,622. Automatic circuit-breakers. C.T. ELECTRICAL CONTROLS Ltd. Nov. 23, 1955 [Jan. 27, 1955], No. 33541/55. Class 38 (5). A double pole circuit-breaker has a pair of current-responsive bimetallic strips 23 acting on the ends of a transverse bar 20, the middle of the bar being connected to a pivoted ambient temperature compensating bimetallic strip 52. In the event of overload, either or each of the strips 23 flexes upwardly and presses on an adjusting screw 24 so raising the centre of the bar 20 to an extent dependent on the mean elevation of the two ends of the bar. The movement of the centre of the bar 20 causes the upward movement of the upwardly bent end 53 of the compensating strip 52 to release a pivoted latch 72 from abutting engagement with a step 76 formed on a cam-like member 77 as shown in Fig. 7. The member 77 moves slightly in an anti-clockwise direction and breaks the overset toggle formed by the operating member 10 and links 89, a spring 84 rotating the member 10. A spring 36 returns the contact carrying bar 33 and a slidable frame 67 on which the parts 72, 77 are pivoted to the off position. The insulating base 11 is moulded to form cavities 16, 17 on the upper side of the base to house the current-responsive strips 23 and a central cavity 15 on the underside of the base to house the compensating strip 52 so as to limit heat transfer from the strips 23 to the strip 52. A passage 19 interconnecting the cavities 16, 17 accommodates the bar 20. The arrangement of the fixed and moving contacts is that described in the divided Specification 812,626.

Title: Electrolytic removal of work material
IPC: B23H3/00
Filed: 1960-09-30
Abstract: An electrolytic tool 26, Fig. 2, for removing work material has a face 50 of insulating material 48 supplied with electrolyte under pressure through tubes 46 which are conductive and also supply the electrolysing current, the tubes being positioned slightly behind the face 50 to prevent electrical shorting with the workpiece.  The electrolyte and current are supplied to the tubes via a chamber 44 by a pipe 40.  The tool is insulated and also has a grounded metallic sheath 52.  In making the face 50, the end of the tool is ground to a smooth flat, concave, convex or other shape and then brought close to a forming tool 56, Figs. 2 and 3, and the ends of the tubes 46 electrolytically eroded until they have receded by a few thousandths of an inch.  In a further embodiment, Fig. 5, electrolyte passages to the working face are formed by brazing together a flat and a corrugated metal sheet 80, 82, units so formed being placed together and the intervening spaces between units being filled by insulating material 83 such as aluminium oxide loaded epoxy resin.  The ends of the metal sheets are electrolytically eroded to leave projecting buttons of the insulating material. Instead of wholly filling the spaces between units with the insulating material 83, strips 100, Fig. 7, may be filled with solder to better distribute the electrolysing current through the stack of units.  Fig. 17 shows an electrode 102 having a surrounding synthetic rubber tube 104 preventing free flow of electrolyte away from the electrode and thus preventing a sharp pressure drop across the interface with the workpiece.  Air blasts may be arranged to blow the electrolyte from <PICT:0969957/C6-C7/1> <PICT:0969957/C6-C7/2> <PICT:0969957/C6-C7/3> <PICT:0969957/C6-C7/4> <PICT:0969957/C6-C7/5> the work face as soon as it has passed the edge of the electrode. The electrode may be hand held. Alternatively, it may be mounted so that it is kept moving over the surface of a workpiece by means of a motor, chain and sprocket mechanism, Fig. 19 (not shown).  A tool, having an arrangement of flat and corrugated plates, Figs. 20 and 21 (not shown), provides for both supplying and removing electrolyte to and from the interface of the tool with a workpiece. Specification 943,101 is referred to.
