Filed: 1950-07-11
Abstract: 678,061. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 15, 1951 [July 11, 1950], No. 17373/50. Class 40 (vi). In an amplifier which may exhibit substantially zero output impedance and infinite inputimpedance, the input is applied to the anode of a first valve 2 and the cathode of a second valve 4, the load being connected between the cathode and anode respectively. An amplified or attenuated signal derived from the input is applied between the grid of valve 2 and cathode of valve 4 while a similar signal is applied between the anode of the valve 2 and the grid of valve 4. It is shown mathematically that by suitable choice of the co-efficients K1, K2 the output impedance may be made zero, the input impedance being negative. By the use of a positive shunt-resistance equal in value to the negative resistance the input resistance may be made infinite with a shunt negative reactance. The valves may be shunted with resistors.

Filed: 1939-12-17
Abstract: 542,263. Gauging apparatus. MAAG, M. Dec. 17, 1940, No. 17792. [Class 106 (ii)] In instruments of the kind in which axial movement of a conical part moves radial gauging elements against the wall of the bore to be measured, one or more rows of cylindrical gauging pins 35 uniformly distributed about the cone 4 and radially movable in a head 3 have their inner ends machined according to the surface of the cone and their outer ends in accordante with the cylindrical surface of the bore 40 to be measured. The head 3 is screwed on to the reduced part 2 of a casing 1. The cone 4 is carried by a shaft 5 arranged with clearance in the bore of the casing so that it can "float," The rear end 5a of the shaft is reduced and surrounded by a spring 7 which abuts between a shoulder 8 on the shaft and a ring 9 secured in the casing 1. A tube 11 passes through slots in the casing 1 and shaft 5 and has secured to it handles 13, 14 which also pass through a sleeve 17 adapted to slide on the casing. The end of the shaft 5 carries a stud 20 adapted to abut against another stud 21 fixed to a micrometer screw 22 having a graduated thimble 27 reading against a mark on a drum sleeve 9 fixed to the casing. In use the micrometer screw is screwed back a pin 33 engaging a flange 32 to prevent excess movement, and the handles 13, 14 used between the fingers to draw the tube 11 to the right. The cone 4 leaves the pins which only have a radial movement limited by screws 36. The head is placed in the bore and the handles 13, 14 released so that the pins engage the surface of the bore. The clearance between the shaft 5 and casing 1 allows the gauge to align properly. The micrometer is now screwed up until the studs 20, 21 engage and the reading read off. If several measurements are to be taken within a lopg bore, an extension piece is inserted between the casing 1 and the head 3. Guiding rings and a scale may be placed along the casing with its zero in the plane of the centre lines of the gauging pins. The second row of pins may guide only and the cone in engagement with these is of slightly less diameter than the cone engaging the gauging pins. A stepped pin 4 having cones of different angle may also be used for gauging ball races. A pivoted stop may be provided to retain the sleeve 17 with the spring compressed. In a further modification a dial gauge is substituted for the micrometer head.
