Title: Improvements in or relating to a method of and means for grinding track-rings for ball or roller-bearings
IPC: B24B19/06
Filed: 1920-10-16
Abstract: 152,612. Aktiebolaget Svenska Kullagerfabriken. Oct. 17, 1919, [Convention date]. Round holes, enlarging and trueing.-The internal spherical surface 2 of the track-ring 1 of a ball or roller bearing is ground by means of a grinding-disk 4, the axis of rotation 7 of which intersects that of the ring at the centre 0 of the spherical surface. The grinding-surface of the disk is spherical and has substantially the same curvature as that required for the surface in the ring, and the axis 7 of the disk is inclined to the axis 3 of the ring so that grinding is performed over an area equal to twice that corresponding to the projection a - e. The disk is fed in the direction of its axis; its surface retains its spherical shape as it wears. The grinding-disk may be stationary and the ring rotated about its own axis and that of the grinding-disk. Reference has been directed by the Comptroller to Specification 148,275.

Patent GB-927420-A (GB)
Title: Single lever engine throttle and clutch control
IPC: B63H21/22
Filed: 1961-08-15
Abstract: 927,420. Regulating. MORSE INSTRUMENT CO. Aug. 15, 1961 [Aug. 22, 1960], No. 29387/61. Class 7(6). A single lever engine control unit comprises a rotatable throttle control member 23, Fig. 1, and a rotatable clutch control member 54 operatively interconnected for simultaneous rotation through a driving connection 21, which is disengageable by axial movement of the throttle control member to permit throttle operation without clutch operation. A 30 degrees movement of lever 24 from the neutral position shown in Fig. 1 causes a 45 degrees counter rotation of clutch control member 54 through shaft 20, pin 39, and drive member 21 which acts through push rod 61 and cable 60 to fully engage the clutch whilst any slight displacement of push rod 43 and cable 46 is absorbed in the cable backlash, without opening the throttle.. Lever 24 is maintained in idle forward and idle reverse positions by detent notches 79, 80. Movement of lever 24 in either direction beyond 30 degrees progressively opens the throttle and causes disengagement of the teeth on drive member 33 and clutch control member 54, and engagement of arcuate surfaces 81 or 82 with circular edge 83 then maintains the arms 55, 56 in their 45 degrees position. Any movement of the clutch control member 54 from the neutral position causes wing plate 70, Fig. 2, to obstruct axial movement of the edge 37 of the throttle control member 23. When both control members are in the neutral position, the shaft 20 can be moved axially against spring 35 to disengage pin 39 from notch 40 in the drive member 21. The edge 37 then engages in a cut away portion 72 of wing piece 70 to prevent rotation of the clutch control arm 54 during throttle opening by lever 24. The open rear of housing 11 may co-operate with a control of opposite hand for twin control mounting. The lever 24 may be selectively positioned by means of splines 25 and the unit may have a push or pull throttle opening action. Spring washer 34 provides braking friction to drive member 21. The relative ratio of the geared members 33, 54 may be varied.

Title: Winding arrangement
IPC: B21C47/12
Filed: 1973-06-21
Abstract: 1380663 Preventing excessive build up at package ends SIEMENS AG 21 June 1973 [22 June 1972] 29630/73 Heading D1J A yarn traverse mechanism has control means that:-(a) determines the instant of reversal; (b) shortens the traverse length if humps appear at the ends of the traverse windings; and (c) reduces the compensatory effect of (b) the reduction being effected at  a rate which is a predetermined function of time.  In Fig. 1 a reversable motor 3 drives a threaded shaft 2 on which a traverse wheel 1 is threaded. As the wheel 1 is traversed to the right of the reel 5 exploring means 12 carried by the wheel 1 responds to the presence of the flange 7 to cause the motor 3 to reverse its direction. The wheel 1 then moves to the right of the reel 5 and when further exploring means 13 carried by the wheel 1 responds to the presence of the flange 8 the motor 3 is again caused to reverse its direction of motion. When lumps are formed adjacent the flanges 7, 8, the increased tension in the materiaal 14 at the reversal points causes a tension sensing device 15 to act on a potentiometer to shorten the traverse stroke. This is achieved by allowing the exploring means 12, 13 to have, under normal conditions, a delay time T between sensing a flange and reversing the motor 3. The tension sensing device 15 shortens this delay time T and so shortens the traverse length.  Thereafter the delay time T is gradually restored at a predetermined rate. The reel 5 is rotated by a motor 10 the speed of which is gradually diminished to give a constant wind-up speed. A detailed circuit diagram is included.

Title: Improvements in or relating to electric conversion systems
IPC: G05F1/32
Filed: 1945-11-09
Abstract: 602,692. Converting; automatic regulation. SHEPHERD, G. R. (Westinghouse Electric International Co.). Nov. 9, 1945, No. 29961. [Classes 38 (ii) and 38 (iv)] An electric conversion system comprises valves controlled by electrodes energized by impulses, the phase of which may be shifted by load responsive primary phase-shifting means having very accurate control over a relatively small phase angle, and also by secondary phase-shifting means controlled by the primary means to maintain the control point within the range of the primary means. A D.C. circuit 11 is supplied from a three-phase A.C. supply 10 through transformers 80, 12 and six rectifier valves of the make-alive type 1-6, each with an excitation electrode 16, supplied from transformer 21 with impulses generated by wave distorting networks 20. The primary phase-shifting means comprises a variable resistance 27 in the supply from transformer 21 through a rectifier 26 to D.C. control windings 25 on saturable chokes 22, 23, 24 associated with the wave distorter networks 20. Resistance 27 is varied by armature 35 moved according to the energization of coil 36 connected across a resistor 45, the voltage across which is proportional to the D.C. output voltage. In the extreme positions of armature 35, contact 32 carried by it engages one or other of a pair of fixed contacts to energize a servomotor 34 from transformer 31 through rectifier 33, so that rotary phase-shifter 30, the secondary phase-shifting means, is rotated in such a direction that the phase of the supply to the firing electrodes through the main windings on inductances 22, 23, 24 is shifted until resistance 27 and armature 35 operate again between the extreme limits. The D.C. voltage in circuit 11 may be selected by a drum controller 37, which varies the amount of a resistor 50 in series with resistor 45. Secondary phaseshifter 30 may be manually operated by switches 76 after movement of change-over switch 75. When the system supplies a D.C. motor 60, Fig. 2, the speed may be controlled by supplying coil 36 from a tachometer generator 61 driven by the motor. Also described is a system, similarly controlled, in which six bridgeconnected make-alive type of rectifiers supply a H.F. oscillator which supplies energy to an induction heating coil such as is used for ten reflowing. Operating coil 36 is energized from a photo-controller responsive to the furnace temperature which is maintained constant.
