Title: A machine for sinking wells, earth boring, mining and so forth
IPC: E21B27/00
Filed: 1936-12-08
Abstract: 491,777. Grab - buckets ; boring earth. SOLOMON, G. J. Dec. 8, 1936, No. 33613. [Class 78 (iv)] [Also in Group XXI] A machine for sinking wells &c. by extraction of earth and having non-rotary earth penetrating means is temporarily clamped to the walls of the hole or lining tubes while the penetrating means is being driven into the ground. The machine comprises a cylinder 1, Fig. 1, in which is movable a cylinder 6 provided with earth penetrating jaws 20. When the machine is lowered to the bottom of the well &c., compressed fluid is admitted through a tube 45 to drive outwardly pistons 35 working in cylinder 33 secured to the walls 1. These pistons clamp the machine to the walls of the well. Movements of the pistons uncover ports 32 so that the compressed fluid enters a chamber 43 to drive the cylinder 6 down and cause the jaws 20 to penetrate the earth. The movement of the cylinder 6 connects the chamber 43 with the interior of the cylinder 6, through a passage 9 and ports 18, 8, to raise a piston 47 in the cylinder 6. The piston rod 3 of this piston is connected to the jaws 20 which are thus closed to grab the earth. The pressure is then reduced and the pressure inside the cylinders 33 returns the pistons 35. The machine is then raised to the surface and a cock opened to connect the passage 9 to the atmosphere so that the piston 47 falls and the jaws 20 open to discharge the excavated earth. The cylinder 6 is connected to the body 1 by rods 40 having pistons or collars slidable in fixed cylinders 26 in which the air is compressed by the downward movement of the rods. For certain grounds, the jaws are replaced by a cylinder 51, Fig. 4, having forked brackets 44 which are mounted in the hinges 7 of the jaws. Holes 48 are provided to allow water to escape from the cylinder 51 as it sinks into the ground.

Abstract: 602,845. Cranes. ALLARD, P. J. M. T. Dec. 13, 1945, No. 33804. Convention date, Sept. 22, 1943. [Class 78 (iv)] In a crane for handling a grab bucket of the kind which is slued automatically when the weight of the full bucket in the raised position is transferred wholly or in part to an auxiliary cable 12 distinct from the hoisting cable 8, the auxiliary cable 12 is attached to the bucket opening head 18, is guided to lie adjacent the axis of the crane post 1 by pulleys 13, 14, passes round a guide pulley 15 carried by the jib extension 16 and is secured at its end 17 to the framework 5 so that when the bucket is suspended from the head 18 a couple is developed producing rotation of the jib 6. When the hoisting cable 8 is wound on the winch 10, the bucket first closes and then is hoisted until it is hooked up to the head 18. By giving slack the bucket remains suspended on the head 18 and exerts a pull on the cable 12 which slues the jib until it reaches the discharge position and by giving slack to the hoisting cable 8 the bucket is opened. The hoisting cable 8 is then pulled, the bucket remains open, the cable 12 loses its tension and the jib returns by gravity, on account of the inclination a of the axis of the pillar to the vertical, to the collecting position. The fixed points may be 17 or 17a to allow for slueing in either direction. In a modification, the bucket is raised by a cable 8 at the same time the auxiliary cable is wound on a drum under the action of a spring or counterweight. At the required height the drum is braked the cable 8 is slacked and the weight of the bucket is transferred to the auxiliary cable. Locking the jib in any slued position may be effected by braking a loose drum carried by the jib and on which is wound a cable, the ends of which are fixed.

Title: Improvements in alternating-current potentiometers
IPC: G01R1/28
Filed: 1927-12-20
Abstract: 294,053. Campbell, A. Dec. 20, 1927. Addition to 244,596. Potentiometers; calibrating instruments. - A variable mutual inductance as claimed in the parent Specification, is connected to resistances and current-measuring devices to form an alternating-current potentiometer, in which the residual frequency errors of the mutual inductance are compensated. In series with the primary winding of the mutual inductance M is a potentiometer slider resistance r and a current-measuring instrument A, a variable shunt resistance S being .arranged as shown. The voltage to be measured is balanced against the voltage v<2>, which is made up of the voltage drop over the tapped-off portion of the non-inductive resistance r and the voltage generated in the secondary winding of the mutual inductance M. The voltage v<2> is calculated from the known values of the resistances r, S, the mutual inductance M, and the current i, the ratio of the shunt resistance S to the resistance R of the branch BC being adjusted in accordance with the frequency. This adjustment is preferably made by a slider F, Fig. 2, which is so arranged that the sum of the resistance R and shunt S is maintained constant. Alternatively, or in addition, switches or plugs may be employed by which resistance can be cut out of R and an equal amount added to S. If the instrument A is inductive, a compensating mutual inductance q, Fig. 3, may be employed. The instrument A may be of the thermal type, for example a heater H, Fig. 4, a thermo-couple Th in series with a direct-current instrument G, a low-resistance shunt K being connected as shewn. In order to set the alternating current i<1> trough the instrument to the desired value, direct current of this value is sent through the heater H and the resistance K, which is adjusted until the galvanometer G gives a zero reading on account of the voltage drop across the resitance K being balanced by the voltage generated in the thermo-couple Th. The direct current is maintained at the same value through the resistance K and the alternating current i' is sent through the heater H and adjusted to maintain zero indication on the galvanometer G. Impurity in the mutual inductance may be compensated for by the arrangement shown in Fig. 5, in which the primary and secondary coils of the mutual inductance M are respectively connected in series with the primary coils of auxiliary mutual inductance m, u, their secondary coils being connected through an adjustable resistance, which may be shunted by a condenser, to form a loop circuit, and means for reversing one or both secondary coils being provided.
