A portable crank-pin machining apparatus comprises an annular casing 5 in which is located an annular worm-wheel 2 which engages a worm 1 mounted in a housing on the periphery of the casing 5, an annular rotor 17 situated within the worm-wheel and connected thereto by a freely movable link 23, the rotor carrying equally angularly spaced crank-pin supporting elements 27 to 30 and a cutting tool and holders 31, 32. The casing, worm-wheel, and rotor are diametrically separable to facilitate the location of the apparatus on a crank-pin in situ. The support elements 27 and 28 are fixable in an adjustable position and elements 29, 30 are radially movable and biased by springs 48 whereby all support elements are retained in contact with the crank-pin surface during machining. The cutting tool 31 is radially adjustable in its holder to determine the depth of cut. The casing with the worm-wheel and rotor are supported in a frame 49 having members spaced axially and on each side of the casing and which are urged into abutment with opposite facing sides of the crank webs adjacent the crank-pin being machined by a jack 60. The frame carries rotatable lead screws 57 transversely spaced one on each side and extending through the casing and which are secured to the casing by a bolt 59 which engages the lead screw thread. In operation, the rotation of the worm 1 effects rotation of the rotor 17 with the tool 31 around the crank-pin on which the apparatus is assembled and the casing 5 with the tool 31 is traversable along the crank-pin by rotation of the feed screws 57. The latter traversing movement is only necessary in cases where the cutting tool length is less than the length of the crank-pin.

Title: Improvements in or relating to frictionless suspensions for the movable elements of measuring apparatus, relays or analogous apparatus
IPC: G01D11/18
Filed: 1945-11-14
Abstract: 613,044. Electrical measuring instruments; suspensions. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Nov. 14, 1945, No. 30488. Convention date, March 2, 1944. [Class 37] [Also in Group XIX and XXXVII] A suspension for the moving element of a measuring instrument or a relay, having slight flexibility in directions perpendicular to the axis of rotation, employs a torsion blade of star-shaped cross-section, one end of which is anchored to the frame of the instrument, and the other end to the moving element. The blade may be cruciform, Fig. 1, or may consist of a number of juxtaposed angular members 21, Figs. 4, 6, fixed together along their lengths and anchored at the ends by blocks 23, Fig. 6, fixed to the support 22 carried by the member to which the suspension is to be attached, or by prisms 25, Fig. 7, under the pressure of screws 26 passing through a ring-shaped support 22. In modifications, the blades 21 are held in position by trunco-conical prisms secured by a clamping ring, Fig. 8 (not shown), or by prisms secured by a deformed elastic ring 22, Fig. 9 (not shown), or by prisms held together by trunco-conical rollers within a ring, Fig 10 (not shown). Parts of the composite torsion blades may be mutually insulated to serve as current leads to the movable member. Dual torsion blades, Fig. 14, may suspend a moving frame 30 from supports 22, between the poles of a magnet 32, the centre of gravity of the moving element lying midway between the supports, while the anchorages may be rigid, or elastic with one or more degrees of freedom. In modifications, the frame 30 may be carried on a single torsion blade, prolongations of the frame being centred in openings in members to limit transverse deflection, Fig. 11 (not shown), or the frame may comprise dual elements between which the torsional blade is situated, transverse deflection being limited by prolongations of the frame moving in openings in a support and the magnetic core, Figs. 12, 12a (not shown). In a movement of the Meylan type, Figs. 13, 13a (not shown), the axis of rotation is a single torsion blade and employs a similar transverse deflection limiting device. Two torsion blades may be placed within the movable frame, Fig. 15 (not shown), and attached to an internal support.

Title: Improvements in or relating to hydraulic pressure boosters
IPC: F16D65/22
Filed: 1960-09-05
Abstract: 966,219. Fluid-pressure brakes. FIAT S.p.A., and P. S. BALDWIN. Sept. 5, 1960 [Sept. 5, 1959], No. 30527/60. Headings F2E and F2F. An hydraulic pressure booster cylinder for vehicle brakes comprises a cylindrical chamber 11 closed at one end by a wall 11a and at the other by a member 12, a connection 31 to a pressure liquid source being provided near the wall 11a, and a piston 13 slidably mounted in the chamber 11 adjacent the wall 11a so that its end wall face is subjected to the pressure liquid and it subdivides the chamber 11 into two chambers A and B interconnected by a passageway, the flow of liquid through which is controlled by a lift valve 26. A reaction spring 20 is interposed between the piston 13 and a washer 21 abutted by an expansible ring 22 carried by the cylinder casing. The valve interconnects the chambers A and B when the auxiliary piston 13 is near the wall 11a at the end of its stroke, but cuts them off after the auxiliary piston 13 is displaced against the spring 20 and prevents return of pressure liquid from the chamber A to the chamber B when the pressure in A exceeds that in B; the spring 20 being mounted under an initial load to allow displacement of the auxiliary piston 13 to occur only when the pressure in the cylinder reaches a predetermined value p1. As shown in Fig. 1, the member 12 is movable and actuates a brake pad whilst the space A is connected through opening 38 to an actuator for another brake pad. In modifications, the lift valve 26 is omitted and the connection between spaces A and B is interrupted by the closure of a passage by the piston itself or by a packing ring carried by the piston. The member 12 may be fired and the space A may be connected to actuators for the brake pads. Specifications 688,382 and 966,218 are referred to.

Abstract: 1313664 Measuring position INTERNATIONAL BUSINESS MACHINES CORP 25 June 1970 [30 June 1969 10 Sept 1969] 30802/70 Heading G4H [Also in Division H1] An electronic position transducing tablet comprises (Fig. 1) position sensing conductors 1 to 15, a corresponding number of capacitors each have one plate 21 to 35 connected to, as shown integral with, a respective one of conductors 1 to 15, means for applying a voltage to the other plate of each capacitor, the individual capacitors having a predetermined relationship one to the other. As shown the other plate of each capacitor is provided by a common conductive plate 17, the different areas of overlap providing the predetermined relationship. A fixed capacitance path to earth for each conductor is provided by plate 19. In this single direction arrangement the voltage appearing on the conductors increases in the X-direction, and may be made to vary linearly, or in any desired manner, e.g. by adjusting the areas of plates 21 to 35. In an arrangement for sensing position in X and Y directions employing phase shifting rather than voltage division, (Fig. 2) instead of plate 17 a pair of complementary X-drive plates 5 and 7 are provided, and a pair of redundant X-drive plates 9 and 10 provide balance and symmetry and ensure that if one of conductors 11 to 25 is broken both pairs continue to function. For sensing in the Y-direction pairs of drive plates 46, 47 and 48, 49 are provided. Electrodes at both ends of the conductors are separated from the corresponding drive plates by dielectric material, as are the X-direction and Y-direction conductors. Electrodes and conductors may be formed by deposition of copper on opposite sides of a polyethylene terephthalate sheet (1) (Fig. 4, not shown) and further layers of dielectric may cover the arrays of conductors. In use the X- and Y-drive plates are alternately driven and earthed. During the X-drive interval, plates 7 and 10 are energized, with plates 5 and 9 earthed, to give an output voltage on lines 11 to 25 which decreases to the left, position sensing being a function of the amplitude. Then all X-drive plates are energized to give a constant reference voltage. The sequence is repeated for the Y-drive plates.
