Abstract: ABSTRACT OF THE DISCLOSURE     A prevailing type torque nut, and method and apparatus for manufacturing such a nut.  The nut is formed with two locally deformed locking portions which are formed in such a way that the remainder of the threads extending between the locking portions is substantially continuous, uninterrupted and undeformed.  As a result, the nut offers greater control over the locking torque characteristics and permits a wider latitude of tolerances.  In accordance with the method of forming the nut, the nut is locally deformed by applying pressure to its outer surface so that the threads will be displaced radially inwardly at localized portions. Means cooperate with the threads intermediate the locking portions to internally support the intermediate thread portions and thereby preclude any substantial deformation thereof during the forming operation.  An apparatus for forming such lock nuts is disclosed which consists of an inner mandrel having a tapered outer section which corresponds in diameter to the crest diameter of the nut threads.  Two reliefs are formed in the mandrel and a cooperating crimping tool is provided which engaged the outer surface of the nut in alignment with the recesses for deforming the nut material into the recesses of the mandrel.

Abstract: ABSTRACT OF THE DISCLOSURE            THIS INVENTION relates to a method for cutting timber into multiple lengths using a power saw guide which includes an elongate support member for supporting a strip and an angle member extending laterally of the support member. The method also includes a power saw guide which comprises an elongate support member for supporting a guide strip and an angle member extending laterally of the support member. The construction and arrangement of the power saw guide is such that in use the guide strip may be supported by the support member with part thereof extending past the support and outwardly from one end thereon.  This enables a laterally extending part of a power saw to be placed adjacent an outwardly extending part of the guide" strip and to bear against an angle member whereby a workpiece comprising an elongate section of timber or other cuttable material may be located adjacent a support member with the angle member extending across thereon.  This enables a workpiece to be cut along a cutting line formed by a free end and the outwardly extending part of the guide strip and the guide point marked on the workpiece to be coincidental with the free end.

Abstract: PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS FROM COAL             ABSTRACT         The overall conversion of coal to synthesis gas by pressurised counter-current gasification is improved by steam reforming the methane values in the gas and heating the steam reformer by means of a fluidised bed combustor fuelled by the coal fines which are too small to be employed in the gasification step.  Coal can be crushed to increase the proportion of fines and/or conditions for gasification and/or steam reforming varied so as to consume lump coal and fines in the desired ratio.   The product gas may be used for methanol synthesis.

Abstract: ABSTRACT          An apparatus is disclosed for measuring the thickness of the corneas and for regulating the depth of a surgical blade in relation to the local corneal thickness.  Corneal thickness is measured by first directing ultrasonic pulses towards the cornea and timing the interval between reflected pulses.  The apparatus also includes a pulse stretcher for enlarging the width of the pulse representing the interval between pulses reflected from the inner and the outer surfaces of the cornea, so that the time between pulses can be accurately measured by a conventional, low-frequency electronic clock.  The invention further comprises electronic gating means for rejecting spurious pulses.

Abstract: Detection Means Abstract In the entranceway between an elevator car and a floor are two oppositely sliding doors.  The approach of these doors is controlled by a detection system that senses the presence of objects between the doors.  This system includes, on each door, a plurality of emitters which are vertically spaced apart the door edge, for radiating noncollimated light towards the edge of the other door.  At the top and bottom portions of each door edge there is a sensor which can receive the radiation from the emitters on the other door edge.  The emitters on each door edge are sequentially turned on and the sensors on the opposite door edge provide a corres-ponding signal as they are turned on, unless an obstruction is in the way, causing the detection system to generate a signal that thus indicates that an object is between the doors.

Abstract: Abstract The invention relates to an expanding means for removable fastening in a cylindric hole, consisting of an elastic cyl-inder, which is caused by axial contraction to expand and with the outer surface to engage with the cylindric hole, which cylinder is formed with a plurality of bars, which extend substantially in the axial direction of the cylinder. It is a   known problem that, when the expanding means is located within a hole in the form of a cylinder, problems may arise in carrying out the expanding proper of the expanding means, because it is difficult for the operator to control by a tool or the like the expanding proper of the expanding means. This problem is overcome in that the bars (7) extend from grooves (8) running in the direction of the bars in the outer surface of the cylinder (1) and outward outside the outer surface.
