Title: The method of manufacturing light-gauge steel sheet, tin-plate and the like
IPC: B21B37/28
Filed: 1956-08-28
Abstract: 796,468. Rolling. INLAND STEEL CO. Aug. 28, 1956 [Jan. 26, 1956], No. 26264/56. Drawings to Specification. Class 83 (4). In a method of rolling light-gauge steel sheet, tin-plate, &c. at least one of the work rolls has a concave contour so that the sheet is formed with a convex cross-section having a crown of at least 0.0005 inches. The rolls are cooled as by water sprays directed over the portion contacted by the work to prevent loss of concavity due to expansion. In one example, slabs of about 0.7-1.0 inch thickness are reduced by about 75 to 95 per cent to about 0.19 inch thickness in three stages, the upper rolls in each stand being about 0.004-0.006 inch concave and the temperature being maintained at 1600-2000‹ F. The strip is subsequently reduced to 0.08-0.093 inches thickness by flat rolls and is finally cold rolled.

Title: Improvements relating to aerial ropeway transporters
IPC: B61B7/04
Filed: 1929-08-30
Abstract: 337,876. Voss, S. Aug. 30, 1929. Overhead travellers and transporters. -An aerial ropeway transporter has one end of the supporting rope fixed to the carrier and the other end passing over a pulley on the carrier and hanging down therefrom so as to support the hoisting device, a balance weight being arranged to counterbalance the weight of the carrier and through a sliding strut to transmit a downward thrust to the hoisting device. The supporting rope b passes over a pulley d or drum on the trestle c, and over a second pulley f on the trestle g. The carrier a has an upper pulley e resting on the upper run of the supporting rope, one end of the lower run being secured to the carrier and the other end passing over a second pulley h on the carrier and extending downwards therefrom and carrying the hoisting device i. The load can be traversed by means of the pulley d. The hoisting rope k passes from a winch m on the trestle c and round pulleys on the hoisting device to the trestle g. A balance weight r is suspended from a rope o passing over a pulley q on the trestle g and under pulleys n on the carrier so as to form a bight passing round a pulley p, the other end of the rope being fixed to the trestle c. The pulley p is mounted on a support s sliding through a guide t on the carrier and mounted on the hoisting device. Thus the balance weight relieves the supporting rope of part of the weight of the carrier and transmits the thrust to the hoisting device causing the hanging part of the supporting rope to be extended and so lessening the sag. The hoisting device may be in the form of a block and tackle.

Title: A phase-modulation transmitter
IPC: H04L27/26
Filed: 1964-06-26
Abstract: 1,079,244. Multiplex signalling. NIPPON ELECTRIC CO. Ltd. June 26, 1964 [June 28, 1963], No. 26503/64. Headings H4L and H4R. In a frequency-division multiplex system, a plurality of incoming pulse coded signals respectively phase-shift modulate a corresponding number of subcarriers in accordance with the pulse signals, the subcarriers being generated by frequency-multiplying the output of a clock pulse generator controlling the repetition frequency of the pulses in the coded pulse trains. As shown in Fig. 1, the incoming signals from a plurality of channels 201 are respectively converted into pulse code modulation at 21, 22 &c. under the control of clock pulses from a clock generator 31. The output of the clock generator, after appropriate frequency multiplying at 41, 42 &c. provides subcarriers separated by the basic clock frequency which are phase-shifted at 51, 52 &c. in accordance with the corresponding pulse coded signals and combined at 61, a local oscillator 63 and frequency-chamber 62 converting the output from 61 into the required frequency band. A receiver is described, Fig. 2 (not shown), in which after frequency-changing to the subcarrier frequency band, the resulting signal is demodulated by combining with the respective subcarriers which are locally generated by frequency multiplying the output of the local clock generator which is synchronized with that at the transmitter. In a modification of Fig. 1, the outputs of frequency-multipliers 41, 42 &c. are supplied via frequency-changers controlled by a common local oscillator to the respective modulators 51 &c. In a further modification, each subcarrier is arranged to have four possible phase shifts so that two incoming pulse code signals may be transmitted by each subcarrier.

Baffles and deflectors.-W a t e r tube boilers of the counter flow type comprise vertical tubes communicating with upper and lower drums and passing through a gas chamber at the upper part of which is a combustion gas inlet. The chamber is provided with deflecting baffles so that the gases pass right across the chamber and then move downward over the tubes. The feed water inlet is in the bottom drum so that water flow is entirely upward. The water tubes 5, Fig. 1, are expanded into dished plates 6 connected by a shell 7, which is surrounded by an outer case 8 also having dished ends 9, which form together an upper drum 11 and lower drum 12 with a free communication by the annular passage 10 and the tubes 5. The feed water inlet is at 33 and the steam outlet at 36. The tubes are grouped symmetrically around the axis with a free central part 13 and wedge shaped part 14, Fig. 2. Beneath the gas inlet 28 is a horizontal firebrick deflector 15, 16 carried by beams 17, 19, the beam 17 being supported on a pillar 21, beam 25, and pillar 26. Vertical gas deflectors 20 and a lower horizontal deflector 22 are also fitted. For facilitating assembly of the central shell, the upper part of the outer case is divided, the parts being secured by flanges 38. In the single set installation, the steel shells may be dispensed with and replaced by a brick casing. In a modification two sets of connected drums and lower headers connected bv vertical tubes are set in a common brick casing and are fed by a single upper gas inlet. The gas inlet may be coupled to a furnace of the kind described in Specifications 19623/12 and 208,607. Specification 8232/09, [Class 123 (ii), Steam generators], also is referred to.
