Title: Improvements in or relating to echo sounders
Inventor: WILLIAMS WILLIAM PETER
IPC: G01S7/60
Filed: 1965-01-28
Abstract: 1,091,773. Echo-sounders. MARCONI SOUNDING DEVICE CO. Ltd. Dec. 8, 1965 [Jan. 28, 1965], No. 3821/65. Heading H4D. In an echo-sounder in which an echo-indicating member repeatedly traverses a depth scale, multiple ranges are provided by differently advancing the time of transmission of an acoustic pulse with respect to the time of commencement of traverse of the scale, and by preventing indication of received echoes during selected regularly recurring traverses of the scale. In the embodiment illustrated, in the Provisional drawing, echo signals are applied to a stylus 1 carried by an endless belt 2 and traversing electro-sensitive paper 3. For recording from overlapping depth ranges nominally of 0-30, 30-60, and 60-90 fathoms, the transmission of an acoustic pulse is initiated at the instant a magnet 5 on belt 2 passes coils 6A, 6B and 6C respectively. The appropriate coil (selected by a switch 7) provides a trigger pulse for a circuit BS which, with switch 8 (ganged to switch 7) on an m contact, acts as a monostable circuit and provides a short duration positive-going pulse for triggering a transmission generator 10 and blanking a receiver 12 during the transmission. For recording from depth ranges nominally of 90-120, 120-150, 150-180 fathoms, trigger pulses are provided by coils 6A, 6B, 6C respectively but switch 8 rests on a b contact so that circuit BS acts as a bi-stable circuit. Transmission generator 10 is triggered by the leading edges of positivegoing pulses of the resulting square-wave output of circuit BS, but receiver 12 is blanked for the duration of each positive-going pulse, and hence echoes will be recorded only during alternate intervals between the trigger pulses applied to circuit BS. In various modifications (not shown), the number of depth ranges may be extended by providing further monostable/ bistable circuits in cascade with circuit BS, stylus 1 may be carried by a lever system instead of by belt 2, and the transmitted pulse may be recorded by passing a signal from the transmission generator to stylus 1.

Title: Prestressed universal rolling mill
IPC: B21B31/04
Filed: 1975-01-29
Abstract: 1445955 Universal rolling stand NIPPON KOKAN KK 29 Jan 1975 [18 Feb 1974] 3865/75 Heading B3M A prestressed universal rolling mill has horizontal rolls 1 and 2 and vertical rolls supported in an intermediate frame 6, upper and lower cross-beams 5 and 7, and tie rods 12 which prestress the parts together. Each rod incorporates an inner bar 64 which stretches the rod when hydraulic fluid is introduced into a cylinder 65 near the base of the rod. In use, the rods are initially stretched hydraulically, nuts 15 at the tops of the rods are tightened and the hydraulic pressure is released, thereby leaving the mill prestressed. To adjust the spacing of the horizontal rolls, the prestressing is released and the rods are rotated in unison by a common motor. The motor rotates worms 33 which cause internally splined worm-wheels 30 to rotate the rods. Rotation of the rods causes sleeves 20 and 23 which are keyed to the rods to rotate in fixed nuts 21 and 24 having threads of different hand. This results in relative movement in opposite senses of the beams 5 and 7 relative to the intermediate frame 6. An upper sleeve 14 and co-operating nut 15 have threads of twice the pitch of those of the other components, to accommodate the adjusting movement.

Abstract: <PICT:0709772/III/1> A process for the wet purification of gas, e.g. coal distillation gas, of the type wherein an alkaline and preferably ammoniacal washing liquid comprising an aqueous solution of sulphur compounds, e.g. thio-sulphate and a water soluble oxygen carrier, e.g. hydroxy benzene, is regenerated by oxidation in a tower-like vessel is characterized in that, the fouled liquid enters the upper part of the oxidation vessel and is regenerated as it passes to the bottom of the vessel for withdrawal whilst the activating air is introduced into the base of the oxidation vessel and escapes from the top of the liquid column leaving behind the sulphur in the form of foam.  The fouled liquid enters the vessel at a point below the liquid level therein.  The raw gas to be treated passes through a pipe 1 into a washer 2 fitted with fillers, e.g. Raschig rings, the purified gas being withdrawn through a pipe 5.  The washing liquid enters the washer 2 through a distributer 4 and contacts the gas over the surface of the fillers, the washing solution, laden with impurities, e.g. hydrogen sulphide, being withdrawn from the base 6 of the washer 2 and passed through a pipe 7 to a pump 8 which raises it through a pipe 9 for discharge at 10 into an oxidation tower 11. Compressed air is introduced into the base of the tower at 12.  The sulphur foam is deposited in a channel-shaped chamber 16 from which it is withdrawn by means of pipe 17.  The regenerated washing solution passes from the bottom of the tower 11 through a pipe 19, to an p  overflow vessel 20, whose height determines the level of the liquid in the tower 11, the washing solution then being returned through a pipe 21 to the distributer 4.
