Title: Combustion-operated pile extractor
IPC: E02D9/02
Filed: 1955-03-14
Abstract: 765,031. Direct-acting engines. DORNFELD, R., and DORNFELD, E., [trading as DELMAG-MASCHINENFABRIK DORNFELD, R.]. March 14, 1955 [April 1, 1954], No. 7440/55. Classes 7 (2) and 7 (3). [Also in Groups XXI and XXVIII] A pile extractor, working on the Diesel principle, of the kind in which a striking hammer 13 serving as the cylinder is guided on a tie rod 10 between an upper striking member 11 and a lower supporting member 12, compression in a combustion chamber 133 being produced by the kinetic energy of the freely falling hammer 13, is characterized in that the hammer 13 has a projection 134 which, when the hammer approaches its upper position, enters a corresponding recess 111 in the striking member 11, the air thus compressed within the recess 111 escaping downwards through grooves 101 on the outer surface of the upper end of the rod 10 to scavange the cylinder space 131 of the hammer 13. In an alternative arrangement a projection is formed on the striking member 11 and a corresponding recess is formed in the upper end of the hammer. The tie rod 10, suspended e.g. from a hoist, not shown, by a bolt 14, is connected at its lower end through a universal joint, part 15 only of which is shown, to tongs, not shown, for gripping the pile to be extracted. The striking member 11 and the supporting member 12 are interconnected by a guide rod 16 which extends through a guide eyelet 17 projecting from the side of the hammer 13. The bottom supporting member 12 is formed to a cone shape on its inner periphery and is mounted upon a split, internally threaded, conical member 152, 153, which is screwed on to the correspondingly threaded end of the rod 10. The split conical member 152, 153, is secured to the member 15 and to the underface of the supporting member 12 by screw bolts 24, additional nuts 25 being provided for withdrawing the member 152, 153. In operation the hammer 13, upon being released, from its upper position, Fig. 1, falls on to a co-operating cylinder portion 121 on the supporting member 12 and commences to compress the air within the cylinder 131. Towards the end of the stroke the hammer 13 strikes the upper end 32 of a fuel injection pump 22 housed in the supporting member 12, fuel being forced through a pressure line 23 and injection nozzle 21 and into a corresponding duct 132 leading to a combustion chamber 133 in the cylinder, or hammer 13. Combustion takes place in the chamber 133 and the expanding gases therein lift the hammer to its upper position where it imparts a blow to the striking member 11, the force being transferred through the rod 10, the universal coupling, and the tongs, to raise the pile. This repetitive procedure can be arrested by operating a cam member 31 to move a catch 30, resiliently mounted in the striking member 11, from a non-obstructing position to a position in which a detent 261 on a rod 26 projecting from the hammer will co-operate, as the latter rises, with a shoulder on the catch 30.

Abstract: 1,004,692. Liquid pressure engines. DOWTY TECHNICAL DEVELOPMENTS Ltd. June 4, 1962 [March 3, 1961], No. 7774/61. Heading F1A. A hydraulic motor, e.g. for actuating a rock drill, comprises pistons 1 and 18 each actuating a valve controlling the reversal of movement of the other. In the embodiment shown, when working piston 1 is in its upper position, pressure liquid passes from an inlet 9 to the lower face of piston 18 via passages 8, 14, 16 and 17. Piston 18 moves upwardly to connect the upper end 4 of piston 1 to pressure via passages 26, 25, 29 and 13. The effective area of the upper end of piston 1 is greater than its lower end so piston 1 is moved downwardly. In the lower position of piston 1 the lower face of piston 18 is connected to exhaust via passages 17, 15, 11 and 12. Since the upper face of piston 18 is of smaller area than its lower face and is continuously connected to pressure via passage 26 and grooves 27, piston 18 is moved downwardly to connect upper end 4 of piston 1 to exhaust via passages 13, 29, 23, 24, 11 and 12. A spring-loaded piston 31, open to inlet 9, acts to reduce inlet pressure fluctuations. Portion 33 is provided on piston 1 to increase its mass.

Abstract: 954,889. Sliding bolts. MINISTER OF PUBLIC BUILDING & WORKS. June 1, 1961 [March 7, 1960], No. 7943/60. Heading E2A. In a locking mechanism for doors of safes or the like in which a door bolt is retracted and advanced by a handle and is securable in the advanced position by a locking member, the handle is connected to the door bolt through an interposed member which is actuated operatively to disconnect the door bolt and the handle as the locking member is moved to lock the door bolt in its advanced position. As shown, a lock mechanism comprises a main bolt 4 and a two-part lever 5 pivotally mounted on a pin 6 on the door and on a bracket 8 formed as an extension of a locking bolt 2. The other end 9 of the lever 5 is provided with a circular hole 10 through which extends a spindle 11 for a door handle. A flanged ring 12 is located in the hole 10 for limited rotary movement and carries a pin 14 which is adapted to engage a recess 15 in a plate 16 carried by the spindle 11, the plate 16 fitting in a circular recess 17 formed in one face of an eccentric 18 freely rotatable on the spindle 11 and located between the bolt 4 and the lever 5. The recess 17 includes a groove 19 which opens at its ends into radial slots 20, 21 located diametrically of the recess. Rotational movement of the eccentric 18 is translated into straight line movement of the bolt 4 by a pair of rollers 22, 23 mounted on the bolt 4 and engaging the eccentric. The rear end of the bolt 4 is recessed for a stop 26 and the adjacent end of lever 5 supports an antiexplosive plate 27 which is interposed between the bolt recess and stop 26 when the bolt is in its shot position. In operation, the pin 14 engages the recess 15 and one or the slots 20 or 21 in the retracted position of bolt 4, so that the plate 16 and the eccentric 18 are keyed together to permit operation of the bolt to its shot position by the handle and locking of the bolt by the lock bolt 2, which action rocks the lever 5 and thereby moves the pin 14 clear of recess 15 to disconnect the main bolt 4 from the handle. At the same time the plate 27 is interposed between the bolt recess and the stop 26. If the door is forced by blowing the mechanism the lever 5 is further rocked to move the pin 14 further away from the plate 16.

IPC: G01S7/60
Filed: 1970-02-19
Abstract: 1287218 Echo sounding SIMRAD AS 19 Feb 1970 [21 Feb 1969] 8061/70 Heading H4D [Also in Division G1] Two categories of signals are recorded by associating each category with a different direction of electric current flow between electrodes EJ on opposite sides of a strip R of electrolytic paper. One category may be supplied by an echo signal receiver and the other by a signal generator producing scale, time or range marks or the categories may be different ranges of dynamic signal level. Applied to recording sea depth by echo sounding signals are supplied to an adjustable amplifier F and amplitude discriminator A and the amplified signals of one polarity or the other are passed by a polarity selector P to a recording pen electrode E so that current flows in one direction or the other between E and an earthed plate J supporting the paper R, which is moistened with an electrolyte. The amplitude discriminator supplies a switching signal to both the amplifier F and selector P whenever the received signal crosses a threshold value at which the marking intensity ceases to increase with the signal level. Below this level signals are recorded on one side of the paper in the usual way but above it the current is reversed so that signals are recorded on the other side and the amplification is reduced so as to double the dynamic signal recording range of the paper, which is made transparent so that the whole echo gram can be viewed from one side.
