Filed: 1921-04-12
Abstract: 179,788. Marks, E. C. R., (Toledo Scale Co.). April 12, 1921. Compound-lever and like apparatus; platform machines.-In a platform lever system comprising long and short levers 10, 11, Figs 1 and 2, each of the short levers is pivotally connected to a long lever by means of two relatively rotatable rings, one of which supports the nose pivots of the short lever while the other is supported from an intermediate pivot located in an aperture in the long lever. As applied to a scale for weighing loaded wagons &c. the platform 1 is hinged to bearings 8 pivotally supported upon the levers which are fulcrumed upon stands 6, the long levers being connected to a shelf-lever 47, which, in this case, is connected to automatic weighing- mechanism of the pendulum type. Within the apertures in the long levers are supported knifeedges 14, Figs. 3 and 6, carrying blocks 15 having depending arms 17, the lower ends of the arms being pivoted to blocks 19 supporting a pivot 25 which is secured to the underside of a plate 21 having posts 22 supporting a ring 23. Mounted loosely upon the ring 23 is a ring 26 formed with lugs 27, within which are pivoted blocks 28 supporting pivots 30 on the arms of the forked ends of the short levers. The bottoms of the grooves in the blocks 28 and the knife-edges 14 are arranged in the same planes. The end of one of the long levers is forked and supported upon blocks 36, Fig. 7, carried by a yoke 37 mounted loosely upon the rod 41 which is connected to the shelf-lever 47 and carries a swivelling-yoke 40 having blocks supporting the pivot 38 of the curved end of the other long lever. The shelflever is provided with an adjustable slide comprised of connected members 50, 51, Fig. 11, the upper member 50 carrying the pivot 56 which is supported in blocks carried by the levers 58. In a modification, the pivot is carried by the lower member of the slide. In another arrangement, the slide is replaced by a channel-sectioned slide open at one side.

Abstract: 1,218,077. Linkwork. INDUSTRIONICS CONTROLS Inc. 7 March, 1968 [15 March, 1967], No. 11104/68. Heading F2K. [Also in Division H1] A switch has an annular plate contact 36 normal to a longitudinal axis along which it is movable towards and from fixed ball contacts 48, 50 (52), the contacting portions of the ball contacts lying in a plane making an acute angle with the longitudinal axis. When fluid pressure in chamber 24 increases rubber diaphragm 20 flexes upwardly and causes plate 36 to engage the nearest contact 48, diaphragm 20 thereafter warping. Plate 36, and a hub 32 on which it rests, then rock about the point of contact (A) with the ball 48 until plate 36 engages the next nearest ball 50. Diaphragm 20 warps more and plate 36 and hub 32 rock about an axis (AB) connecting the points of contact of plate 36 with balls 48 and 50. This causes plate 36 to engage ball (52). The rocking movements of plate 36 produce a tangential force which rotates plate 36 about part 42 of hub 32 in an epicyclic manner in a clockwise direction (Fig. 2), this rotation cleaning the contacts and reducing wear. Plate 36 also has a limited transverse movement on part 42. A nylon or polytetrafluorethylene washer 38 is provided between parts 36, 32. The outer circumferential edge of hub 32 may extend up around plate 36. The balls are a snap fit in a holder 30. Springs 58, 60, respectively connect balls 48, 50 to conductors 88, 90, an electrical insulating washer 56 being provided. A spring 62 with an adjusting screw 76 bears on a pin 66 with a rounded surface 68 fitting into a socket 70 in hub 32 to provide a universal joint. Ball (52) may contact neither spring, or it may contact spring 58, ball 48 being dead. Plate 36 may have a sloping contact surface and the contacting portions (A, B, C) of the balls may be in a plane normal to the longitudinal axis.

Title: An improved apparatus for use in oil and like wells
IPC: E21B29/00
Filed: 1928-04-17
Abstract: 299,677. Ferguson, J. April 17, 1928 Milling - machines.-Superfluous lengths of oil-well casings are cut out and removed by means comprising a planetary milling-cutter with radial feed. The cutter is suspended in the well by a series of tubes 5 connected by screwed couplings each tube supporting a section of driving-shaft 4 by means of a ball race or washer at its upper end. The shaft sections are squared at their lower ends and formed with corresponding sockets at their upper ends, and the assembled shaft is driven from fast and loose pulleys through universal joints and a telescopic shaft 12 and bevel gearing 8 supported above the well. Reduction gearing is housed at 27. A further telescopic shaft transmits motion to the cutter 3 which is mounted in a slide in a slotted tube 21. A bar 35 slides in guides in the tube and is slotted to engage a pin 23b in the cutter slide. A screw 36 engages a nut secured to the bar 35 and is fixed to a guide frictionally engaging the well tube by contact pads 39<a> carried by spring arms. The screw 36 is thus held stationary during rotation of the tubes 5 and attached tube 21 causing the bar 35 to slide through its guides. The slot in the bar is of curved form to feed the cutter radially at a diminishing rate and return the cutter slide after the casing is severed without reversing the driving gear. Slow rotation of the tubes 5 to impart the orbital movement to the cutter is imparted by worm gearing 15 driven by ratchet gearing 32 from an adjustable throw crank on the end of the shaft 9. Two pawl carriers are provided one driving on the up stroke and the other on the down stroke and each pawl carrier has two pawls spaced to the effective pitch of the ratchet wheel in order to provide a fine adjustment for the rate of the orbital motion.. The ratchet wheel is secured to its shaft by a friction clutch to enable the motion to be disengaged. To adjust the radial position of the cutter slide to suit different diameters of casing a series of spaced holes for the pin 23<b> provide a coarse setting, the slide itself being in two parts bolted together with interposed shims for a fine setting. A second set of spring pads 19<a> engage the casing above the plane of the cut.

Title: Anodising selected areas of thin metal films
Inventor: DUCKWORTH ROGER GEORGE
IPC: C25D17/14
Filed: 1963-03-21
Abstract: A method of anodizing thin metal films in which the area to be anodized is restricted by using the capillary action of a wick to convey electrolyte to the anode.  The method can be used for adjusting the value of resistors, e.g. Tantalum resistors, by producing a selected thickness of oxide thereon. Since the colour of the metallic film is dependent upon the thickness of the oxide layer, metal films may be coloured for artistic purposes by using the wick in a painting action.
