Title: Traffic detection apparatus
IPC: G01S13/87
Filed: 1945-07-20
Abstract: 616,534. Road signals for controlling traffic. AUTOMATIC SIGNAL CORPORATION. July 20, 1945, No. 18645. Convention date, June 29, 1944. [Class 118 (ii)] [Also in Group XL (c)] In a traffic control system ultra-highfrequency electromagnetic waves are periodically and sequentially directionally propagated via a plurality of wave-guides, the wave reflected from an approaching vehicle being utilized to operate traffic signal or control apparatus, warning signal devices or counting apparatus. A transmitter-receiver 10 (Fig. 2) generates frequency - modulated ultra - high - frequency waves which are transmitted by an antenna 16 along a wave-guide 11 which terminates in four flared horns HN, HS, HE, HW facing four traffic lanes. A suitable flare angle is said to be 50 degrees. A motor-driven switch 22 by means of a cam 20 sequentially operates gas discharge gating tubes TW, located one in each horn, three at a time, the ionization produced permitting transmission from only one horn at any instant. A vehicle in the lane served by the horn whose " gate " is open will reflect back the transmitted wave to the antenna 16, the resultant beat frequency, which is indicative of the distance of the reflecting vehicle, being amplified and passed to output leads 30, 31. Relay devices RE, RW, RS, RN are sequentially connected to the output leads 30, 31 by a cam 33 of the motordriven switch 22 during the period when a corresponding horn HE ... HN is transmitting. Thus when, say, horn HE is transmitting the beat frequency produced by a vehicle at a certain distance will operate the relay RE which in turn operates traffic signal or control apparatus, counting apparatus, or warning devices. The wave-guides 118 (Fig. 8) may branch into two guides 118A, 118B, each with its own gating device and each associated with a directional horn transmitting in two directions, E-W and N-S. In order to avoid transient effects, the relays RE ... RN are switched into circuit after their respective gate tubes are quenched, and switched out before the tubes are fired again. The mechanical switch 22 may be replaced by a multi-vibrator circuit.

Abstract: 789,181. Sharpening machine cutters in situ. FELLOWS GEAR SHAPER CO. June 18, 1956 [Aug. 4, 1955], No. 18775/56. Class 60. [Also in Group XXII] A gear shaper comprises a cutter-sharpening hone, abrasive tool or file 32 mounted on a support 30 and means for reciprocating the support in time with the cutter. The support 30 is movable transversely on a slide 29 movable vertically on a baseplate 27. In operation, with the cutter C mounted on its spindle, the baseplate 27 is secured to the cutter saddle by a bolt 26. A screw 38 is then adjusted so that its head 39 abuts the upper face of the cutter C. When the cutter moves downwardly, it carries with it the tool 32, the movement being assisted by a spring 46 acting on the slide 29. The support 30 is anchored by a link 50 to a pivot 51 on a rod 48 attached to the baseplate, so that, as the support is pushed downwardly, the tool 32 is moved transversely across the edge of the cutter C. At the same time, it is given a slight rotational movement by a pawl acting on a ratchet wheel 31. When the cutter moves upwardly, it abuts the head 39 to raise the slide 29 together with the tool 32. A spring 35 holds the tool in contact with the cutter, and the link 50 causes an opposite transverse movement across the cutter edge. A second pawl also gives the tool a further rotational movement. Specification 435,702 [Group XXII] is referred to.
