Title: Vane test probe primarily for underwater use
IPC: E02D1/02
Filed: 1976-07-09
Abstract: 1492325 Measuring shear strength of soils SOIL INSTRUMENTS Ltd and GOLDER HOEK & ASSOCIATES Ltd 9 July 1976 [14 July 1975] 29467/75 Heading G1S A probe for measuring the shear strength of soils, particularly that of underwater sediments, comprises a casing 1 with one end defining a cylinder 3 having an open end and housing a piston 4, a coupling 9 for connection to a test vane 30, Fig.2, a drive housed in the casing for applying a torque through the coupling to the vane and means to move the piston 4 away from the open end of the casing whereby the vane and case are drawn into the soil by the suction created. Piston 4 is connected to piston 5 within a cylinder 8, the cylinder 8 being connected to hydraulic lines 6, 7 connected to supply lines A, B. A non-return valve 20 is included in line 7, and a bleed valve 21 is connected to the lower part of cylinder 8. The drive comprises a piston 15 slidable but non rotatable in cylinder 16, hydraulic lines 17, 18 coupling the cylinder 16 to lines A, B, a rotatable but axially immovable shaft 10 connected to coupling 9, a member 12 rigidly connected to shaft 10 and having a helical channel 13, and rollers (not shown) at 14 carried by piston 15 and engaging channel 13. Shaft 10 carries a strain gauge 19 for measuring the torque applied. In use, with pistons 4, 5 in their lower positions and piston 15 in its upper position, the probe is lowered down a borehole and the vane 30 penetrates the soil on impact. Hydraulic pressure applied to line A causes piston 5 and hence piston 4 to move to their upper positions, the suction induced in cylinder 3 causing the vane and casing to penetrate further into the soils. Hydraulic pressure is then applied to line B to cause piston 15 to move downwardly to apply torque to the vane, movement of pistons 4, 5 being prevented by non-return valve 20. In  the detailed construction shown in Fig.2, shaft 10 is hollow and carries wires 31 from strain gauge 19. The shaft 10 acts as the supply line A and includes ports 32, 33 for applying pressure to pistons 5 and 15. Supply line B applies pressure to piston 15  via coupling 34 and line 17, and conduit 6 extends through shaft 10 to a port 35. Piston 15 is restrained from rotation by pins 36A engaging a slot 36. Thrust bearings 37, 38 locate shaft 10 longitudinally.

A self-equalizing band-pass filter comprises a hybrid-T waveguide junction having a pair of conjugate arms terminated by resonant cavities of different loaded Q-factors, the other pair of arms forming input and output and containing waveguide resonant cavities. As shown, a magic-T junction 3 is provided with an E arm 5 matched to the junction by an iris 12, and an H arm 4 matched to the junction by a post 11. The arms are reflectively terminated by resonant cavities coupled to respective arms by posts 14, 13, these posts being of different diameters so that the cavities have different loaded Q-factors. The input and output arms 1, 2 comprise identical post-coupled cavities providing a band-pass filter. It is shown in the Specification that the construction shown is equivalent to a lattice network comprising resonant arms coupled to input and output band-pass networks. The Specification discusses in detail how the group delay and attenuation characteristics of such a network can be independently determined whereby a band-pass network having constant group delay may be realized. The lumped equivalent circuits (Figs. 5, 6, not shown) take no account of the finite lengths of waveguide between the junction and the coupling posts 15 of the band-pass filters or those between the junction and the coupling posts 13, 14 of the cavities in the H and E arms. It is shown that these lengths are critical. They are determined by experiment.

Title: Improvements in, or relating to, steam heated machines
IPC: F24D1/00
Filed: 1946-10-09
Abstract: 630,973. Ironing- - machines. SPIRAX MANUFACTURING CO., Ltd., and MILNES A. Oct. 9, 1946, No. 30101. [Class 138 (ii)] Each of a plurality of zones a in the bed of an ironing-machine is heated by being included, together with an inductor e, in a separate selfcontained steam-circulating system to which pressure steam is fed from a supply line b common to all the zones, the flow of pressure steam through the inductor being arranged to induce the circulation of steam through the system and the steam discharged from the zone being returned to the inductor. This arrangement has the effect that, for any given setting of the inductor and any given pressure in the steam supply, a maximum velocity is imparted to the steam flow through the zone so as to increase the tendency for any-heat-transfer film on the walls of the zone to change from the condition associated with stream-line flow to that associated with turbulent flow. Steam is fed to each inductor e from the main line b through a branch pipe c containing a valve d, and both the outlet and suction sides of each inductor are connected to the associated zone a. In the line f between the suction side of the inductor and the zone are included a condensate separator g and thermostatic air vent h, the separator discharging to a condensate main m through a strainer j and steam trap k. The steam outlet h<SP>2</SP> of the vent h is arranged at a lower level than the inlet h<SP>1</SP> and is controlled by a thermostatic valve; the lower part of the vent h comprises a chamber which is provided with an air outlet h<SP>3</SP> adapted to be closed by the thermostatic valve when the outlet h<SP>3</SP>, adapted to be closed by the thermostatic valve when the outlet h<SP>2</SP> is opened, and opened when the outlet h<SP>2</SP> is closed. The temperatures of the different zones may be so controlled as to provide a pre-determined temperature gradient throughout the machine. The invention is also described as applicable to steam-heated machines generally.
