[Also in Groups XXII and XXIII] A tool assembly for. use in a machine for generating or measuring bevel gears comprises at least one pair of broaches having identically shaped and dimensioned cutting edges 59 or measuring elements. Four such broaches, each having sets of identical teeth, are clamped in position by one or more bars 6 on a tool-carrier 4. The carrier is mounted on a slide 1 which is reciprocated for operative cutting strokes in each direction by gearing 47, 48 as described in Specification 749,901. The broaches cut alternately on the down and up strokes and are indexed by rollers 14, 14<SP>1</SP> on spring-pressed carriers 15, 15<SP>1</SP>, the rollers engaging a cam 13 at the end of each stroke to rotate the carrier 90 degrees. The carriers are locked in position by plungers 24 which are released at the end of each stroke by plungers 33, 33<SP>1</SP> and linkage 29, 30. The broaches cut only one tooth flank on each stroke and it is therefore necessary alternately to oscillate the gear blank 8 by adding a rotary component of motion in a clockwise and an anti-clockwise direction to position it correctly in relation to the broach. The machine may be used for gauging tooth surfaces by replacing the cutting tools by teeth having feelers which can be deflected against resilient means when they engage an inaccurate portion of a flank. Modifying tooth form.-In the Provisional Specification it is stated that tip or root relief or crowning may be imparted to the teeth as in Specification 718,101.

Abstract: 746,269. Geiger counters. TEXACO DEVELOPMENT CORPORATION. May 8,1952, No. 20396/55. Divided out of 746,172. Class 39 (1). In a plate-type radiation detector as described in Specification 612,899 comprising a plurality of cathode plates 22 and an anode wire 24 extending through aligned apertures 25 in the cathode plates, travel of the ion sheath along the anode wire is limited by means of conducting plates 23 mounted between groups of cathode plates. The plates 23 are of the order of two to three times the thickness of the cathode plates and are of slightly less diameter. The anode wire 24 is maintained at the operating potential E<SP>1</SP> of the counter and extends through aligned apertures 26 in the plates 23, these apertures being of less diameter than the apertures 25 in the cathode plates. A bus-bar 27 connected to the plates 23 and passing through apertures in the cathode plates maintains the plates 23 at a potential E<SP>2</SP> such that the field strength in the apertures 26 is insufficient to sustain ionization along the anode wire and will thus block the travel of the ion sheath. The period during which the detector is insensitive is thus reduced so that high counting rates are possible. The counter is filled with gas at a low pressure, for example a mixture of argon and alcohol at a pressure of 5-20 inches of mercury. The invention is applicable to detectors of the plural anode type as described in the parent Specification.
