Abstract: 1314459 Riveting HUCK MFG CO 23 April 1971 [7 May 1970] 11184/71 Heading B3U A tool for torquing and crimping a nut 48 to a bolt 50 comprises an impacting assembly 24 and fluid motor 22 for torquing the nut to the bolt, and crimping jaws 32 which are reciprocated relative to an inclined surface 42 of a housing 38 by a piston 18 so that coaction of the surface 42 with the jaws produces radially inward and outward movement of the jaws. In operation balls 98, which engage helical grooves 100 of a drive member 78 and slots 102 of a collar 88, are moved axially by rotating the drive member by a shaft 86 of the motor 22. The axial movement of the balls 98 moves the collar 88 rearwardly until projections 96 on the collar disengage from teeth 94 on a flange 76 of a member 70. The load in a spring assembly 90 will then urge the collar 88 forward and the action of the balls 98 in the grooves 100 will result in the collar 88 rotating rapidly. The engagement of teeth 94 with the projections 96 provide the torque to the member 70 so as to torque the nut on to the bolt. The piston 18 is then moved rearwardly so that the coaction of the inclined surface 42 with the surfaces 44 of the jaws 32 will move the jaws 32 radially inwardly until teeth 46 engage and crimp the nut.

Title: Improvements in and relating to thickness gage
IPC: G01B5/06
Filed: 1935-04-12
Abstract: 445,812. Linear - dimension gauges. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Pratt & Whitney Co. ; 436, Capitol Avenue, Hartford, Connecticut, U.S.A.) April 12, 1935, No. 11346. [Class 106 (ii)] Comprises a construction of calliper gauge for continuously measuring the thickness of sheet material. A bracket 11 is adjustable laterally over a support 10 and carries by means of a parallel linkage 13, 14 a gauging head 12 which is counter-balanced by springs 15 attached to the bracket and link member 14 and may thus be moved vertically to accommodate itself to varying vertical positions of the strip W due to increasing thickness of the winding roller. An arm 16 pivotally mounted on an axis within the head 12 is acted upon by a spring 17 and carries at the free end a gauging roller 18 opposed to a similar roller 18 carried by the head, the sheet material W passing between the rollers. At one side of the head is mounted an anvil 21 movable vertically within small limits to vary the position of a flexibly supported armature located between two opposed coils within the casing 20. Opposite the anvil 21 is a screw adjusted anvil 24 mounted within the arm 16. A clamping screw 27 locks this anvil. On the head, adjacent the rollers 18 is a movable anvil 29 directly opposed to an anvil 30. The former is moved by rotating a graduated dial 31 past a fixed mark. The spindle carries a pointer 32 moving over a scale 33 indicating complete rotations of the spindle. A standard gauge block 35 is first placed between anvils 29, 30 and the disc 31 made to read zero. The rollers 18 should now be just in contact, if not, the spindle is adjusted to make them contact and the scales adjusted to zero. With the gauge block 35 in position, the spindle 29 is adjusted so that the rollers are separated by a gap corresponding to the thickness to be measured. The spindle 24 is then adjusted until the position of the armature is such that the instrument 36 reads zero, when the apparatus is ready for measuring departure from standard as the sheet is passed through. Specification 365,138 is referred to.

Abstract: 1,177,496. Control of D.C. motors. PARAMATIC DEVELOPMENT Ltd. 6 March, 1968 [11 March, 1967], No. 11603/67. Heading H2J. A member is caused to oscillate about a desired position (to overcome " stiction "), the magnitude of the oscillations being limited by " damping means " effective only when the oscillations are present. The member is the shaft of an electric motor M, which at a particular angular position engages contacts XY which control a transistor circuit to energize the motor to run in one or the other direction according to whether they are open or closed. Thus, the motor continuously oscillates about the mean position, the contacts XY opening and closing. The " damping " is provided by a resistor R11 in series with the motor and this is shunted by a transistor T10 held non-conducting by the charge on a capacitor C3 which is maintained by the output of a rectifier bridge B1 supplied alternately through capacitors C1 and C2 as XY opens and closes. Thus, when the oscillations cease when the member is driven to a new position the output from B 1 also ceases, the charge on C3 leaks away through R 10 and T10 conducts to supply full power to the motor so that it runs to a position at which oscillation again takes place. The contacts XY may be operated by a photo-electric cell arrangement, in which case, to prevent the motor assuming a stable position with the cell half obscured, a capacitor is connected to X and a suitable part of the transistor circuit to provide positive feedback. In Fig. 2 (not shown), the motor has a split field to provide reversals.
