A grinding machine for externally grinding ring-shaped workpieces, e.g. ball-bearing races W, comprises two parallel power-driven spindles 1, 2 to drive the workpieces during grinding; a magazine disc 3 mounted on an indexing shaft 14 and having a plurality of workpiece recesses 8-11 to be brought successively into correctly disposed position relative to the spindles 1, 2 by rotation of the shaft 14, a workpiece loader 4 and a workpiece ejector 5, the recesses each having a peripheral opening 7 on one side to allow entry of a grinding stone 6. A workpiece mandrel 12, 13 is arranged coaxial with each spindle and is adapted to advance into the respective workpiece recess during grinding and to retract out of the recess during indexing. Each workpiece mandrel effects hydraulic pressure centring of a workpiece and carries a loose-fitting locating sleeve 15, also centred by hydraulic pressure, by which sleeve the workpiece is urged against the corresponding spindle during grinding. In the machine described, the mandrels 12, 13 are non-rotatably carried for axial reciprocation by tailstock sleeves 12a, 13a. In operation a workpiece W is loaded at station I and indexed to station II with the mandrels 12, 13 retracted. The sleeves 12a, 13a are then advanced so that the mandrels enter the workpieces and the workpieces are urged against spindles 1, 2 by sleeves 15. The workpieces are rotated and ground whilst they and the sleeves 15 are supported by hydraulic fluid, e.g. oil supplied via holes 27. After grinding the sleeves 12a, 13a are retracted, the mandrels withdrawn for indexing and the workpieces stripped off the mandrels by the sleeves 15 as the latter engage fixed collars 25 on the sleeve housings 26. After a pre-finish grinding at station II and a superfinishing at station III, the workpieces are ejected by ejector 5. The grinding stones may be oscillated during grinding.

Abstract: 1,265,823. Pulse radar. McDONNEL DOUGLAS CORP. 24 March, 1969, No. 15383/69. Heading H4D. In an aircraft collision avoidance system the radio signal is modulated by the output of an altitude encoder 22, Fig. 1, received signals are demodulated to compare " other " with " own "  aircraft altitude, frequency-sensitive means determine range rate between " other " and " own " aircraft and a reply signal generator responsive to the frequency-sensitive means transmits a reply signal at a precise instant relative to the receipt of the signal from the other aircraft whenever they are at substantially the same altitude and are closing. In the embodiment a relatively long pulse 28, Fig. 2, is followed by a pulse 30, the interval between the pulses being proportional to the altitude of the interrogating aircraft; a co-operating aircraft (provided that the altitude and closing conditions are met) replies with a modulated pulse after a delay: when the two aircraft remain the same distance apart (as evidenced by zero Doppler shift) there is an arbitrary delay T w  but for a closing range rate R and an arbitrary " warning " time T the reply pulse time position is given by T early  = 2RT/C, where C is the propagation constant. The modulation of the reply pulse is coded for identification and may also carry an instruction to climb or dive to the interrogating aircraft. The interval T A  = T w +2/C(R-RT), where R is the distance between the aircraft: a warning signal is generated only when T A <T W . All co-operating aircraft use the same carrier frequency, and the receipt at an aircraft of an interrogating signal may cause the transmission of an interrogating signal from it for a predetermined time, to prevent interference. The interval 2(RT - R)/C at the interrogating aircraft represents the estimated distance of the responding aircraft after time T.
