Title: Improvements in rock drill feeding devices
IPC: E21B44/08
Filed: 1961-04-10
Abstract: 908,878. Rock drills. ATLAS COPCO A.B. April 10, 1961 [April 12, 1960], No. 12872/61. Class 124. [Also in Group XXIV] A rock drill feeding device comprises a support 19, a double-acting feed cylinder 12, reversing valve means 47 (Fig. 3) for supplying fluid to either side of the piston 69 for relative reciprocation of the piston and cylinder, unidirectional locking means 28 engaging the support, and means for connecting a rock drill 10 to the cylinder or the piston, the locking means being connected to the piston or the cylinder so that the drill is advanced step-bystep in one direction along the support during reciprocation of the piston. The drill is pivoted to a saddle 14 sliding on the support which has a centralizer 21 for the drill steel. The drill is connected to the cylinder so that fluid from a bore 22 and main valve 23 on the drill passes to a reduction valve 45 on the cylinder. The locking plate 28 which is pivoted to the pistonrod 13 at 27 is pressed in a clockwise direction by a ball 36 carried by a sleeve 30 (positioned as shown) so that the sides of slots 29 grip the support when the drill is advanced. The sleeve may be turned by a handle 32 through 180 degrees so that the plate is pressed in an anticlockwise direction during withdrawal of the drill. A similar locking plate 28<SP>1</SP> is fixed to the cylinder. As shown in Fig. 3, the valve 47 is held in its left-hand position by a spring- pressed ball 63 engaging a groove 62, the valve having been moved during the preceding leftward movement of the piston by means of an abutment 67 and the intermediary of a sleeve 66 and spring 72. In this left-hand valve position pressure fluid flows through duct 46, grooves 53, 50, 54 and duct 59 (Fig. 6) to the portion 60 of the cylinder, whilst the portion 58 of the cylinder communicates with the exhaust 56 through duct 57 and grooves 52, 49, 51 so that the piston moves to the right causing plate 28 to grip the support, and the cylinder to move to the left to advance the drill (the plate 28<SP>1</SP> sliding over the support). At the end of an advance movement of the drill an abutment 68 contacts a spring 73 to move the valve rapidly to the right, the stop engaging a groove 61. In this right-hand position of the valve pressure fluid is supplied to the portion 58 through duct 46, grooves 53, 49, 52 and duct 57, while the portion 60 is connected to the exhaust 56 by passage 59 and grooves 54, 50, 55, so that the piston moves to the left, the locking plates 28, 28<SP>1</SP> respectively freely sliding over, and gripping the support. In Fig. 6, the piston is shown as it nears the end of its leftward stroke just before the valve is rapidly moved by the abutment 67 for a new advance stroke. During continued operation of the piston the drill is fed along the support step by step. The drill is retracted by turning the sleeves 30, 30<SP>1</SP> to reverse the gripping directions of the plates 28, 28<SP>1</SP> and by operating the piston.

Abstract: 177,428. Steven, A. May 6, 1921. Mines, marine.-Relates to apparatus of the kind comprising a net supported by buoys and having air-chambers supporting bomb-chambers from which bombs are released when the net is encountered by a submarine. According to the invention, each bomb-chamber 4, Figs. 2 and 4, contains several bombs instead of only one as heretofore; and these bombs maintain the bombchamber 4 and its air-chamber 5 at a given depth. When the bombs are dropped by the release of a catch 6 by a pull from the net 2, the air-chamber 5 rises to the surface where its position is indicated by a pointer 7 projecting above water. The net 2 is made in sections attached to pairs of air and bomb chambers hung from surface buoys, Fig. 2, or supported by horizontal chains or wires 14, Fig. 3, between the buoys 1. This Figure shows a modification in which each bomb-chamber 8 is a drum divided into sections each containing one bomb. The drum is mounted on a spindle 10 carried by the air chamber 11, and is rotated by a pull from the net which opens the sections and drops the bombs one after another so long as the pull continues.

Title: Electric conductors for signalling purposes
IPC: H01B11/14
Filed: 1926-05-21
Abstract: 255,025. Felten & Guilleaume Carlswerk Akt.-Ges. July 9, 1925, [Convention date]. Drawings to Specification. Loading circuits to improve transmission.-In a cable having a layer of ferromagnetic loading material for the purpose of increasing self-inductance, the damping for a definite permeability is minimized by making the thickness of the layer such that the continuous current resistance of the cable is equal to 5p1 + p2 + #L tan #. p1 being the eddy current resistance of the layer, p2 the hysteresis resistance, w the angular - frequency, # the angle corresponding to the losses in the insulating material, and L the selfinductance. In practice, # can be substituted for tan #. Applying this rule for #=7000, which gives little distortion, and taking a mean value for the loss constants, it is found that a suitable thickness of layers is given by d=7u-2/3mm. for the usual sizes of telephone cables.

A rotary vacuum-pump 12 immersed in oil has suction pipes 22, 24 connected by a cylinder 20 for a spring-loaded spool-valve-member with a piston 26. When the pump is not operating the valve member abuts a stop 42 and the piston has to the right of a sealing ring 40 in engagement with another sealing ring 38 so as to first shut off the pipe 24 and then admit air above the oil to the pipe 22 through a small vent 34, thus preventing the oil entering the pump and the pipe 24. When pump is in operation an anxiliary vacuum pump 16 partially exhausts a space 21 to shift the valve member to the position shown. Alternatively, the piston may be controlled by either a solenoid energized directly or indirectly by a generator, Fig. 2 (not shown), or a centrifugal governor, Fig. 3 (not shown). As another alternative, the piston 26 is replaced by a piston 64 engaging with a fixed piston 70 with a hollow stem 71 connected to a hydraulic pump 60. When the pump 12 is inoperative air enters the pipe 22 through ports 74, 76, the piston 64 being shifted to the left by hydraulic pressure when the pump is operating. A vent 76 relieves pressure in the stem when the piston moves to the right. To prevent the piston 26 oscillating, the ring 40 may be replaced by two rings with an air vent there between, Fig. 5 (not shown).
