Title: Improvements in or relating to thread rolling heads
IPC: B21H3/04
Filed: 1963-07-01
Abstract: 985,852. Rolling screw threads. NARADI NARODNI PODNIK PRAHA. July 1, 1963 [July 16, 1962], No. 264045/63. Heading B3M. A thread rolling head comprises thread rollers which are eccentrically mounted on shafts which can be adjusted for angle of skew, the rollers being automatically disengaged from a workpiece after a predetermined length of thread has been rolled. Each of three rollers 15 is mounted on an eccentric portion of a shaft 10 which is supported by part spherical bearings 6 in plates 1 and 12, Fig. 3a. The curved ends of each shaft are restrained by plates 2 and 21. Rotation of plate 1 relative to plate 12, after loosening clamping screws 4, alters the angle of skew of the rollers. The plate 21, which includes an annular outer portion, is rotatable on the body of the rolling head, but is normally prevented from rotation by projections on a ring 31 which engage grooves in a member 30 which is bolted to the plate 21. During rolling, in which the head is attached by a flange 22 to a rotating machine spindle, a workpiece is gradually fed between the rollers and eventually contacts an adjustable stop 42. The stop is axially shifted and moves the ring 31 out of engagement with the ring 30, thus allowing a spiral spring 29 to rotate the plate 21. Each shaft is thereby rotated and the rollers are moved radially from the workpiece. A lever 18 on each shaft is turned by a pin 20 which is either attached to the plate 21, or to the lever 18 itself, Fig. 4a. A brake 33 rotatably mounted on the ring 30 has a lining 34 and can be shifted by an operating fork, not shown, to disengage the rings 30 and 31 and thus cause the rollers to move apart. A handle mounted on the outside of plate 21 is used to manually reset the rolling head.

Title: Improvements in or relating to locking mechanism for automobile trunk compartments
IPC: E05B65/19
Filed: 1939-09-18
Abstract: 534,840. Multiple bolt fastenings. BASSICK CO. Sept. 18, 1939, No. 26095. Convention date, Sept. 21, 1938. [Class 44] A bolt fastening particularly for the lid of an automobile trunk compartment comprises two oppositely directed bolts 38 pivotally connected at 39 to a central rotatable bar 36 operable by a handle 34 to shoot and retract the bolts. To allow for curvature of the lid 12 the bolts are curved or angularly bent as at 58, the outer ends being straight and parallel to the line of movement of the bolts. The operating mechanism is carried by a mounting plate 20 riveted at 21 to a stamped up central part 19 of a frame member 17 secured to the lid for stiffening purposes and provided with off-set portions 18 which carry guides 62 for the bolts. The bolts are of channel section to give rigidity, the guides 62 being bent to conform to the channel section. The ends of the bolts engage behind channels 11 around the edges of the fixed frame 10, the free edges seating on a rubber packing 15 carried by the lid. The bolt ends are bevelled by being bent at an angle or, as shown in Fig. 3, by bending the base of the channel section as at 66 and closing the side flanges at 67 over a filling piece 68. The ends of bar 36 are spaced away from plate 20, against which transverse beadings 35 bear at opposite sides of a raised resilient portion 23 of the plate defined by slots 25 of which the mid-portions are arcuate as shown. A bushing 26 secured in an aperture in the bar 36 by swaging is pivotally mounted in the resilient part 23 so that slight axial displacement of the bushing on handle spindle 33 is permitted. An H-form bowed spring 49 carried by spindle 33 below a cotter 51 bears against bar 36 and holds the handle 34 against an escutcheon having a curved flange 53 enclosing a rubber sealing ring bearing against the outer face of lid 12, the escutcheon being secured in the door by stamped up spring tongues 57 which snap into engagement with the inner face of the lid when the escutcheon is inserted. Movement of bar 36 in both directions is limited by the edges 41, 42 of a rectangular stop 40 struck up from plate 20. Bar 36 is retained in its extreme position by engaging by resilience of part 23 behind the rounded edge walls 44 and 48 or 45 and 47 of rectangular raised portions of plate 20 over which the bar rides in moving from one position to the other. An L-shaped lever 69 pivoted at 70 is held by spring 71 so that its longer arm, guided under a strap 72, is normally held in the path of arm 36. as shown, Fig. 7, to prevent clockwise movement of the arm to retract the bolts, but can be moved by a pivoted cam 75 operable by a barrel lock 80 to clear the arm and allow retraction of the bolts. This construction allows the cam to be placed in locking position when the bolts are still retracted, the lever arm yielding to allow the arm 36 to be subsequently moved to shoot the bolts, the lever arm then springing back into locking positions.

Title: Improvements in dynamo-electric generators for electric welding
IPC: B23K9/067
Filed: 1922-09-29
Abstract: 208,268. Mawdsley, J. H. St. H. Sept. 29, 1922. Exciting.-A dynamo 1, Fig. 1, for electric welding supplies continuous current to the electrodes 3, 4 and, by means of slip-rings 2, it also supplies alternating current to the electrodes through a transformer 5 until the arc is struck. The welding current is steadied by a reactance 7, which may be in two parts a, b, the part b being short-circuited by the switch 6 when this switch is opened to disconnect the alternating supply after the arc has been struck. In the form shown in Fig 2, the commutator of the machine 1 excites a continuous-current machine 9 which is connected to the electrodes, to which the sliprings are also connected directly. A transformer may alternatively be used in the alternating- current circuit as in Fig. 1. When a number of electrodes is used, each set of electrodes has a set of reactances and automatic switches.

Title: Aircraft radar receiver
IPC: G01S13/70
Filed: 1972-06-06
Abstract: 1391682 Pulse radar ELECTRONIQUE MARCEL DASSAULT 6 June 1972 [8 June 1971] 26342/72 Heading H4D  In an automatic ranging airborne pulse radar utilizing a search phase preceding the tracking phase, false operation may arise in low flying due to ground echoes when a target is beyond a range corresponding to the altitude of the aircraft. According to the invention this problem is ameliorated by desensitizing the receiver at this range. In an embodiment, the gain of the I.F. amplifier in unit 12 is controlled by the output of a pulse shaper 25 Fig. 5 (not shown): the output of a radio altimeter affords a pulse, Figs. 2, 4 (neither shown) from a generator 20 to actuate a gate 18 to allow video to pass to peak detector 17 and thence to shaper 25 whereby the amplifier is desensitized according to the design of the shaper. Switch 27 is thus not switched to "tracking", position 29. Target tracking is not interrupted when the target is at a range equal to the altitude, as switch 27 is in position 29. The maximum amplitude of the desensitizing pulse is dependent on the peak amplitude of the altitude echo; thus the range within which target searching is ineffective is limited. An indication may be given to the pilot when the target is at a range corresponding to the altitude.
