Abstract: 1,037,714. Semi-conductor circuits; stereophonic radio signal receivers. RADIO CORPORATION OF AMERICA. May 29, 1964 [June 19, 1963], No. 22314/64. Headings H3T and H4L. An electronic switching circuit comprises an insulated-gate field-effect transistor having a rectifier coupled between the gate and source electrodes and arranged to provide a low impedance path for signals of a polarity tending to decrease the source-drain resistance of the transistor. Synchronous detectors.-Fig. 4 shows a circuit for demodulating the suppressed carrier signals in a stereophonic radio receiver, under control of pilot carrier signals at 51. Rectifiers 55, 56 become conductive during the respective positive half-cycles of the push-pull pilot signal, so as to charge capacitors 53, 54 in such a way that the insulated-gate field-effect transistors 43, 44 become conductive only during the respective peaks of the pilot signal and hence charge capacitor 64 to the instantaneous value of the modulated wave fed to transformer 60. In Figs. 6, 7 (not shown), the capacitors 53, 54 are replaced by resistors so that the detector operates on average instead of peak values. Fig. 9 (not shown) relates to a synchronous detector similar to one half of Fig. 4 but having the suppressed carrier signal supplied to the source electrode 45. Fig. 10 (not shown) relates to a synchronous detector in which the suppressed carrier signal is fed in parallel to the two drain electrodes of transistors 43, 44, the demodulation being controlled by a half-frequency pilot carrier fed in push-pull to the gate electrodes.

Title: Bore concentricity gauge

Filed: 1963-06-06
Abstract: 1,021,211. Concentricity gauges. A. EISELE. June 6, 1963, No. 22519/63. Heading G1M. A bore concentricity gauge comprises a measuring pin 106 reciprocable in a transverse bore in a member 16 and having a bevelled surface 128 which engages an inclined transversely curved lip 132 on a rod 134 which moves in a longitudinal bore 136 and thus transmits movement of pin 106 to dial indicator 14. The axes of the pin 106 and rod 134 are not quite perpendicular to facilitate motion. In use the member 16 is inserted in the bore to be measured and an enlarged portion 110 engages a counterbore. The gauge is then rotated and movement of pin 106 is caused if the bore and counterbore are not concentric. The member 16 is interchangeable for different bore sizes.

Title: A new or improved stapling mechanism
IPC: B27F7/23
Filed: 1938-07-28
Abstract: 517,453. Stapling. QUICK, C. G., and FOWLES, R. W. July 28, 1938, No. 22520. Addition to 492,891. [Class 89 (iii)] The rotary stapling mechanism of the parent Specification is modified in that the male stapleforming member is given an angular movement relatively to the radius of its cylinder, so that it may remain in engagement with the female member for an extended period, and the staple driving plunger is caused to recede as the male member enters the female member. The male members 7, 8 are carried by crankpins 67, 68 on planet gears 73, 74 which are rotated, as the cylinder 1 rotates, by a sun gear 75. The radial, staple-forming, movements of the members thus effected are supplemented by a swinging movement caused by arms 77, 78 mounted on the crank pins and controlled by slots 79, 80 and studs 81, 82. Thus, each member, as it enters the female member 28 or 29, is maintained substantially radial to the cylinder 2 for an extended period. The cylinder 2 is recessed to accommodate the arms and studs. The staple-driving plungers 92, 93 are controlled by links 96, 97, bell--crank levers 98, 99 and cam surfaces 105, 106, 107 so that they recede as the members 7, 8 enter the female members, are then held from movement, and finally are moved outwardly to drive the staples through the web W against the clenching anvils 45. The cylinder 1 comprises two cheek plates between which the crank pins and arms are accommodated.

Abstract: 404,748. Sockets. BATES, F., and BATES, T., Trukut Works, Hazelwell Lane, Stirchley, Birmingham. Aug. 13, 1932, No. 22764. [Class 83 (iii).] A centre-drill &c. is provided with one or more spiral grooves, independent of the usual flutes, for engagement with a plunger projecting into the bore of a socket. One or more spiral grooves 14 are provided in the cylindrical body 10 of the drill extending from one conical end 11 to the other, for engagement with a plunger 18 by means of a combined axial and rotary movement of the drill in the socket 15. The plunger may be attached to a part circular spring 19 embracing the socket, as described in Specification 404,735, and exerts sufficient force against the sides of the groove to drive the drill under normal conditions but permits the drill to yield under excessive torque. Any tendency of the drill to rotate in the socket, within the limits of strength of the spring 19, forces the conical end of the drill into contact with a similar seat 17 in the socket. The grooves 14 are preferably formed in the stock from which the drills are subsequently cut off, by milling, grinding &c. or by rolling or drawing during the final finishing operation. The plunger 18 may be replaced by a ball or plunger pressed by a spiral spring into the bore of the socket, or one or more fixed or integral projections may be disposed in the bore.

In an embodiment, the hole in the plate 10, Fig. 3, is provided with a countersunk end 12 and the tube 11 is inserted into the hole with its end flush with the plate surface after which the tube end is swaged into the countersunk portion 12. A welding electrode 15, Fig. 4, having a conical contact surface 16 and a pilot guiding section 18 fits within the countersunk portion and is applied with a strong pressure so that a ring weld 14 Fig. 3, is formed. For a tube of 0.25 inch outside diameter, radial thickness 0.010 inch, chamfer 45 degrees and 0.050 inch chamfer length a pressure of 100-200 lbs. is suitable. The electrode may have a part spherical surface to provide a ring weld intermediate the ends of the shaped portion. In an alternative embodiment the side is not countersunk but is parallel sided, the tube end being flared and positioned slightly above the plate surface to be thrust into the hole and welded by an electrode having an end 19, Fig. 6, tapered in a curve. The method is applied to the manufacture of a heat exchanger for a marine turbine plant comprising tubes of austenitic stainless steel secured to header plates also of austenitic stainless steel.
