Title: Well tool
IPC: E21B33/1295
Filed: 1967-09-12
Abstract: A retrievable bridge plug for a well bore has expanding grips for the bore wall which are urged against the wall by a pressure differential across the seal in either direction. The plug has a body 10 with a central bore 11 communicating with ports 12 (at the bottom) and 17 (near the top) in the body which facilitates sinking the plug in a liquid filled well. The plug is lowered by a tube string which engages a socket 14 and sleeve valve 20 for the port 17 at the top of the plug. Expandable grips 70 are resiliently mounted on a cage 50 mounted by buttressthreaded split nuts 57, 58 on the body 10. Further wall grips 53 hold the cage against rotation so that the body can be rotated to release the nut 57, the nut 58 then engaging threads 63 (Fig. 5B, not shown so that on continued rotation, the body is screwed down inside the cage and the grips 70 are pressed against the wall by a conical skirt 73 of a piston 36, and at the same time the plug seal ring 31 is compressed between the piston 36 and an abutment 27 on the body, and squeezed against the wall. When the tube string is disconnected from the socket 14 it also lifts the sleeve valve 20 to close the port 17, which would otherwise by-pass the seal 31. The top of the piston 36 is in communication with the bore below the seal 31, and the bottom of the piston is in communication, via bores 80, 81, 82 with the bore above the seal. Thus, if the pressure below the seal is greater than that above it, the piston will be urged downwardly and through the conical skirt 73, will increase the force on the grips 70. If the pressure above the seal is greater, then the pressure on the seal is transmitted by abutment with the flange 30 to the piston 36, and the resultant force is downwards. That is, the top of piston 36 is effectively always subjected to the greater of the two pressures, and partial areas beneath the piston are subject to each of the pressures, so that the resultant force is always downwards. In a modification, (Fig. 6, not shown), the flange 46 below the piston 36 is replaced by a free piston.

Patent ES-348631-A1 (ES)
Title: Improved Hydraulic Lifting Jack
IPC: B66F3/42
Filed: 1967-12-26
Abstract: An hydraulic lifting jack comprises a base 2 with a hollow cover 1, a mounting plate 4 fixed on the base 2 with two spaced bores 4A, 4B respectively mounting an upstanding cylinder 5 and a housing 6. A ram 5A is movably mounted in the cylinder 5 and carries an extension screw 5C in a threaded bore 5B. An operating plunger 6A is slidably mounted in the housing 6. Space 8E below the ram 5A is in communication with the interior of the housing 6 through passage 4C in the plate 4, slots 9A, 9B respectively in the cylinder 5 and housing 6 being provided for this purpose. The cover 1 forms a reservoir for hydraulic fluid, the normal level being indicated by the dot-dash line in Fig. 5. Fluid is drawn from the reservoir through a suction valve body 13A when the plunger 6A is raised by raising a handle 19 inserted into a handle socket 16 pivoted on a pin 16B in a bracket 17 pivoted on a pin 16D on the cover 1. The handle 19 has a cut-out flat 22 normally arranged over the top of the plunger 6A so that the latter clears a spring-loaded ball 11 at the bottom of its normal stroke. On reciprocation of the plunger 6A fluid is forced past the ball 11 under the ram 5A to raise the latter. To release pressure and lower the jack the handle 19 in the down position shown is rotated axially when the full diameter of the handle 19 engages the top of the plunger 6A. This produces over-riding of the non-return action of the ball 11 allowing fluid to flow from under the ram 5A via slot 9A, passage 4C, slot 9B past the ball 11 and through a slot 14 in the plunger 6A and a part 12A back into the reservoir.

Title: Improvements in or relating to harvesting machines
IPC: A01D57/04
Filed: 1969-06-26
Abstract: A harvesting machine has means for vertical and longitudinal adjustment of the crop pick-up means, as shown the pick-up reel of a combine harvester, the adjustment in both directions being by a common drive means, e.g. jacks 31 operated electrically, pneumatically, or hydraulically. The reel shaft 16 is journalled at each end in a bearing 17 attached to a sleeve 18 slidably mounted on an arm 19. The other ends of arms 19 are respectively attached to tubes 21 rotatably mounted on a transverse tubular shaft 22 which itself is free to rotate in support brackets attached to frame 1. Welded to each end of shaft 22 is a triangular plate 28 which has pivotally mounted at two of its apices respectively a rod 33 pivotally attached to the sleeve 18 and the piston rod 30 of the ram 31. In the lowered position the arms 19 engage rest supports 20. In energizing the rams, rotation of the plates 28 produces longitudinal movement of the reel as the sleeves 18 slide along the arms 19 until abutments on the sleeves contact adjustable stops 27 on the arms 19 when further extension of the rams results in a predominantly vertical movement of the reel as the arms 19 rotate about the transverse tube 22. After extending the rams springs 35 attached respectively between rods 33 and arms 19 are tensioned and thereby effect the return of the reel to its rest position as the rams are de-energized. Alternatively a double acting ram may be used to obviate the necessity of the springs.

Title: Method of making a nipple-electrode joint
IPC: H05B7/14
Filed: 1972-02-03
Abstract: The invention relates to nipple-electrode assemblies and joints, such as those used in electric arc furnaces, and to a means of distributing thread clearance throughout the assembly and/or joint. These means include the pre-positioning of the nipple in the socket of the electrode section into which the nipple is threaded so as to provide a clearance between the non-load bearing flanks of the threads of said threaded nipple and said threaded electrode socket and the placing within the space between the base of the nipple and the bottom of the socket of the electrode section a hot, non-gaseous fluid, carbonizable material which solidifies upon cooling, thereby preparing a preassembly wherein the nipple is fixed in the electrode section, thereby maintaining the aforedescribed pre-positioning and thread clearance and thereby also providing room for thermal expansion of the threads of the connection. The hot, carbonizable material is introduced into the space between the base of the nipple and the bottom of the socket, while in a hot, fluid condition, through a hole in the nipple after the nipple has been threaded into the electrode socket, after which the carbonizable material solidifies. Upon connection of the projecting end of the nipple into a socket of an electrode section and use in a column of electrodes in an electric arc furnace, the solidified carbonizable material again becomes heated, melts and some of it flows downwardly through the hole into the corresponding space in the socket of the electrode section of the column and then becomes solid and carbonizes due to the heat encountered, thereby locking the nipple in the sockets of both electrode sections joined.
