Title: A method and means for the detection of cobble in continuous rolling mills
IPC: B21B33/00
Filed: 1960-09-01
Abstract: 932,587. Rolling. SOUTH AFRICAN IRON & STEEL INDUSTRIAL CORPORATION Ltd. Sept. 1, 1960 [Sept. 15, 1959], No. 30128/60. Class 83 (4). Means for detecting cobble in a continuous rolling mill comprises a pair of detectors CD, DP, Fig. 1, such as photo-cells, flap devices or electric contacts arranged to detect the arrival of the material at two different points and to give a warning signal if the material does not arrive at the second point DP within a predetermined time after its arrival at the first point CD. The warnings ignal may merely operate a warning lamp C1, but is preferably used to operate flying shears FS to cut the remainder of the following material to scrap and thereby prevent the build-up of cobble. The first detector CD may comprise an induction coil as described in Specification 932,587 and which is normally used to initiate operation of the control FSC of the flying shears FS for cropping the leading end of the material. The detector CD in this case also initiates operation of a time delay relay TU through switch A and which after a preset time set by rheostat TA operates through a triode valve V1 to close the solenoid switch B in the warning signal circuit of lamp C1 and of a control FSSC for initiating continuous scrap cutting by the shears FS. The second detector DP comprises an electrically insulated guide tube for the finished material which when connected to earth by the moving material closes a circuit through solenoid RC to open switch C in the warning signal circuit. When the material arrives at DP within the preset time of the delay unit TU, the warning signal circuit is thereby prevented from operating.

Abstract: 602,943. Augers. CLARK, R. H. Nov. 12, 1945, No. 30209. Convention date, Dec. 6, 1944. [Class 83 (iii)] An adjustable auger comprises a body 10, a shank 26 sweated in a central hole 25 in the body and projecting at the bottom to form a feed screw 14 and a main cutter 12 projecting laterally from the body and adjustably secured thereto by a clamping plate 34 which also forms a core cutter. The cutter 12 is of triangular section with a cutting edge 30 hollow ground on the face 31 above it and a depending cutting lip 39; it is fitted in a V-shaped groove in the lower end of the body, tilted so as to afford cutting clearance behind the edge 30, and bears a scale on the rear face co-operating with the intersection of the groove with the outer surface of the body. The clamping plate 34 is secured to the body by a screw 35 and has formed on it a cutting edge 51 and cutting lip 52 diametrically opposed to each other. During cutting the clamp plate bears in the bore formed by the lip 52 and steadies the tool. To clear shavings, the clamp plate is cut away at 70 and the body has a flat side 23. The feed screw 14 is tapered over the lower portion and the extreme tip is shaped to have several small plane faces to prevent injury to the tip. In a modification, Fig. 7, the clamp plate 34a is a flat plate with a part turned to form a blade 50a; it may also have a depending cutting lip.

Title: Doppler V.O.R. Systems
Inventor: EARP CHARLES WILLIAM
IPC: G01S1/40
Filed: 1966-07-08
Abstract: 1,183,318. Radio beacons. STANDARD TELEPHONES & CABLES Ltd. 7 July, 1967 [8 July, 1966], No. 30757/66. Heading H4D. Specification relates to a Doppler VOR beacon system wherein to improve the phase accuracy of the 30 c/s. reference signal at the receiver a harmonic of the reference signal is transmitted with the bearing signal. The beacon of Fig. 2 comprises 50 antennµ 21 evenly arranged in a circle and a central reference antenna a51. Commutating means simultaneously convey the respective outputs of amplifiers 24 and 25 to diametrically opposite antennµ in the circular array. The commutating means are rotated at 30 c/s. by means of motor 23 synchronously energized by the output of "by n" divider 26, which is fed in turn by the 30n c/s. output of generator 212. The 30 c/s. output of divider 26 also amplitude modulates the carrier output of generator 27 in modulator 214, the output of which is used, via amplifier 218, to feed reference antenna a51. The output of 9960 c/s. generator 216 amplitude modulates the carrier in modulator 213 and the resulting upper and lower sidebands are respectively separated out by filters 211 and 210 for feeding as carriers to modulators 29 and 28. The modulating signals for 29 and 28 are antiphase signals at 30n c/s. from phase shifter 215 and generator 212. The thus modulated sideband signals are fed via amplifiers 25 and 24 to the commutating means. At the receiver. Fig. 4, the bearing and 30 c/s. reference signals are derived from the detected received signal in the normal manner (i.e. the 30 c/s. bearing signal from the 9960 c/s. filter, frequency discriminator and 30 c/s. filter, and the reference signal from the 30 c/s. filter). The additional modulation on the bearing signal at 30n c/s. (690 c/s. in this example) is derived from the I.F. signal by means of frequency discriminator 43 and 690 c/s. filter 44. Squaring and differentiating circuits 45 and 47 convert the 690 c/s. signal and the 30 c/s. reference signal to corresponding pulse signals, which are fed to a pulse gate circuit 46 wherein the phase of the 30 pps. reference pulses are corrected by means of the 690 pps. pulses. In the beacon of Fig. 3, the 30n c/s. signal amplitude modulates the 9960 c/s. signal at 31 and the resulting modulated signal is used to amplitude modulate the carrier at 213. The 90n c/s. or 690 c/s. is then separated out at the receiver, Fig. 5 (not shown), by means of amplitude detecting the output of the 9960 c/s. filter in the bearing signal chain. As an alternative to the pulse gate circuit 46 a phase shifting arrangement, Fig. 6, may be used to correct the phase of the 30 c/s. reference signal, the phase shifter 63 being controlled by the detected difference output of a sum and difference detector 61 fed with the 690 c/s. and the corrected 30 c/s. reference signal. The output of detector 62 is positive or negative and controls the action of diodes 77 or 78, Fig. 7, in the phase shifter, respectively enabling phase advance (73/74) or phase retard (75)76) loops.
