Inventor: WALKER R A
IPC: B25B23/145
Filed: 1975-09-18
Abstract: A tightening system and method and a fastener assembly usable therewith are disclosed in this specification. According to the method a fastener assembly is provided that causes a change in the slope of the torque-rotation curve which could be plotted while the joint is being tightened, which change occurs at a known load. While tightening the joint, the torque applied to the fastener assembly when the slope of the torque-rotation curve changes is noted and is used to calculate the torque necessary to induce a desired load in the joint. Additional torque is applied to the fastener until the actual torque being applied substantially equals the calculated torque. The tightening system includes a wrench for tightening the joint and a control system associated with the wrench including a system responsive to the change in slope of the torque-rotation curve for calculating the torque corresponding to the desired load to be induced in the fastener assembly and for shutting off the tool when the actual torque corresponds to the calculated torque.

Abstract: A gate valve structure for use in large diameter mains carrying fluids under high pressure, the gate valve structure being provided with an improved annular resilient seal for engaging a valve seat of the type where the valve seat provides for a face-seal and an edge-seal with intermediate sections making both a face-seal and an edge-seal. The annular resilient seal member is provided with a pair of arcuate bulges oppositely disposed thereon at positions to engage the face-seat surface of the valve seat adjacent the face-seat surface's minimum radial thicknesses to provide an increased contact in this area when the gate member is in the closed position. Additionally, the improved gate valve structure utilizes opposed ribs in the elongated chamber of the casing, the ribs being received in guideways or recesses in the periphery of the gate member so as to guide the gate member during opening and closing. Such an arrangement permits the use of smaller and lighter valve casings for large diameter mains.

Title: Magneto-mechanical converter for control relays - has soft iron core mounted between two like pole pieces and attracted by altering field strengths (HU 27.2.82)
Inventor: VEISZ GYORGY
IPC: H01H50/16
Filed: 1982-01-15
Abstract: The magneto mechanical converter allows relays to be made simpler and cheaper with straight forward manufacture using standard equipment. Such relays may be used over a wide range of parameters from milli amps and milli volts to kilo amps and kilo volts. They may be operated by direct current or alternating current at any frequency. For a well defined value of exitation current the elements of the converter can be adjusted to change position relative to each other very precisely in either action or reset. When the action current is reached it produces a movement with a large starting torque which may be used not only for opening and closing contacts but also for transmitting mechanical forces. Operation of the relay is not orientation dependent and a wide range of applications is envisaged in situations where control relays are used. The converter consists of a soft iron core with a permeability greater than 1.2 which is not energised, held on a flexible support between two like poles of two magnets which face each other and produce a variable magnetic field. In the rest position the core is held close to one pole piece and there is a null field in the centre of the pole gap. As the field strength of the one magnet is increased the null moves towards the core and the other pole piece, the core is demagnetised and remagnetised to be attracted towards the other pole. The field strength corresponding to the change of direction can be determined with great precision. Practical realisation of the device contain permanent and electromagnets with adjustable pole pieces and preconstrained springs.

Abstract: Device for the parallel guidance of an elongated luminaire along a support, in particular a drawing board, the luminaire being mounted pivotably and displaceably on both sides via means in each case of a bent-back arm at a bearing point arranged on the reverse of the support.

Abstract: In order to produce mineralic bodies of high porosity, usable inter alia as adsorbers, purifiers and catalyst carriers, a predominantly mineralic mass with organic admixtures-both preferably obtained from industrial waste products-are subjected to a three-phase treatment. In a first phase, the mass is heated in an inert or reducing atmosphere to a sintering temperature between about 1000 DEG  C. and 1350 DEG  C. whereby the organic constituents are carbonized and partly penetrate the consolidating mineralic structure. In a second phase, still under the same nonoxidizing atmosphere and at the sintering temperature referred to, the mineralic structure is sintered into a coherent matrix. In a third phase, with reduction of the temperature to a lower level between about 600 DEG  and 1000 DEG C. and exposure to the atmosphere, the carbonaceous substances occluded in the mineralic skeleton are burned off to increase its porosity.
