Title: Improvements in gauges for measuring or comparing diameters of cylindrical bodies
IPC: G01B5/08
Filed: 1951-07-12
Abstract: 706,210. Linear-dimension gauges. RAE, J., and BLAXLAND RAE, PTY., Ltd. July 12, 1951 [July 14, 1950], No. 16586/51. Class 106 (2) A gauge for measuring and comparing internal or external diameters of cylindrical bodies comprises a ring having a contact diameter slightly larger than the diameter to be gauged, the ring having an arcuate work engaging face and having a substantial depth relative to its radial thickness so that it is flexible in its own plane and substantially inflexible in any other plane. Fig. 10 shows in cross section an example of a ring 26 for gauging bore holes, the ring having a known outer diameter that is slightly greater than the diameter of the bore hole. On forcing the ring into the bore hole the ring assumes an elliptical shape in a plane inclined at an angle to the plane normal to the longitudinal axis of the bore hole. This angle is a measure of the diameter of the bore hole. The ring 26, Fig. 7, may be rotatably held in a shouldered recess 30, Fig. 5, formed on the periphery of a disc shaped plate 31, by the heads of four screws (not shown) screwed into the holes 32. The circle joining the outer edges of the four screw heads is less than the external diameter of the ring 26. The diameter of the recess 30 is less than the undistorted internal diameter of the ring 26 to permit reduction in the ring diameter when distorted. A bubble vial V, Fig. 13, may be provided at the end of a handle 33 secured to the plate 31 for use in determining the angle of tilt of the ring 26 in the bore C. Fig. 11 shows in cross section an example of a ring 18 for gauging external diameters of cylinders, the ring having an internal diameter slightly greater than the diameter to be gauged. If the ring is caused to closely embrace the cylinder being gauged the ring will assume an elliptical form and the inclination of the plane of the ring to the plane that is normal to the axis of the cylinder is a measure of the diameter of the cylinder being gauged. Figs. 1 and 2 show a holder 15 for the ring 18. The ring 18, Fig. 3, is held in a recess 19 in the holder 15 by retaining washers on screws (not shown) located in threaded holes 20. The diameter of the groove 19 is greater than the undistorted external diameter of the ring 18 so as to accommodate the elliptical shape assumed by the ring when it is distorted. A bubble vial 17 is preferably mounted in a projection 16 of the holder 15 to assist in determining the inclination of the ring 18 when gauging the diameter of a cylinder.

Patent GB-168830-A (GB)
Abstract: 168,830. Shanklin, B. M. Feb. 10, 1920. Feeding webs. - In strip-feeding mechanism adapted to advance a perforated strip towards punching or marking apparatus having severing means, to ensure that the strip is accurately fed, main and supplementary feeding mechanisms are employed consisting respectively of feed rolls and pawls on a spring-controlled lever. The ticket strip passes from a roll 17 through a passage i' between plates i, 18, the second of which carries sets of punches 21 corresponding to the time, date, and transfer point. Selectively set parts for operating the punches are carried by a frame p, as described in Specification 166,458, [Class 106 (iii) Fares, &c.], and capable of downward movement against springs 30 on the rotation of a cam 93 carried by a shaft 92. Movement is imparted to the shaft 92, on the depression of the operating pedal, through a rod 79 and a lever 80 engaging a pin on an arm 82 carried by a spring- retracted shaft 83. A toothed sector 90 secured to the shaft 83, during its clockwise movement, rotates the shaft 92 through a pinion 94 and a one-way clutch and causes the cam 93 to depress the frame p. On the return of the sector 90 under the influence of its spring 86, movement is imparted to the lower feed-roll 96 through a pinion and a ratchet clutch, the upper roller 97 being carried by pivoted arms 108, Fig. 2, and held in the feeding position by springs 110. Toward the end of the driving movement of the sector 90 the feed-rolls are separated to allow the supplementary feeding means to come into operation by cams 117 on the ends of the shaft 98 of the lower feed-roller. Normally the lower feed-roll is locked by a lever 102 pivoted at 103 and provided with a notch which is held in engagement with a pin 104 on the roller by a spring 106, a cam 105 on theshaft 83 serving to remove it from the locking position. The supplementary feeding device comprise a series of spring-controlled pawls 120, Figs. 3 and 4, carried by a lever 119 pivoted at 118 and adapted to be forced forward by a bow spring 124 through a slotted link 122 connected to the upper end of the lever 119 and guided on the shaft 103. During the feeding movement of the roller 96, a cam 125 on the shaft 98 of the roller forces the pawl-bearing lever 119 to the rear and allows it to move forward when the upper feed-roller is raised, the pawls engaging the ticket perforaticns and feeding the strip, slowly at first and then more quickly, under the influence of the spring 124. Separation of the feed-rolls to allow manual adjustment of the strip is effected by means of a slide 115 which is connected by a wire 114 to a bell-crank lever 111 serving to raise the upper roller 97 through a link 113. Reference has been directed by the Comptroller to Specification 166,242, [Class 31 (i), Cutting and severing machines &c.].

Abstract: 470,300. Valve generating and amplifying circuits ; cathode - ray tubes. GENERAL ELECTRIC CO., Ltd., and DIPPY, R. J. June 18, 1936, No. 16978. [Classes 39 (i), 40 (iii), and 40 (v)] The ray of a cathode-ray tube is deflected by the magnetic field produced by coils in the output circuits of a pair of similar valves in pushpull connection, the coils being so constructed and located that under normal conditions no resultant magnetic field is producedto deflect the ray. Two windings, one on each side of the tube, may be provided in the circuit of each valve, and the windings from the two valves on the same side of the tube may be wound on a common former. As shown, windings 1 and 2 are in the output circuit of valve 4, and windings 1<1> and 21 in the output circuit of valve 4<1>. The pair 1 and 2 are arranged, in known manner, one on each side of the tube 3 to produce a uniform magnetic field within it, and so are the pair 1<1>, 2<1>. The windings being arranged so that when the normal current flows through them the field from one pair neutralized the field from the other pair. The coils 1, 1<1> are preferably wound together on the same former, and so are the coils 2, 2<1>. When a signal arrives the current in 1, 2 changes in one direction and that in 1<1>, 2<1> in the other so that the effects reinforce each other. If only one winding is provided for each valve, the two windings should be on the same side of the tube.
