Title: Improvements in or relating to soldering irons
IPC: B23K3/06
Filed: 1949-06-25
Abstract: 675,973. Soldering and brazing. HERSEE, L. R. June 26, 1950 [June 25, 1949], No. 16915/49. Class 83 (iv). A soldering-iron has a trigger connected to solder gripping means constituted by two parts which embrace the solder and which are movable relatively with a controlled movement for gripping the solder so that complete penetration is avoided and means associated with the trigger engage the gripping means after the relative movement is completed to move the gripping means and the solder bodily to feed the solder towards the bit and means for withdrawing the solder from the bit during part of the return movement of the feed mechanism are provided. A member 15 provides guides 16, 17 for the solder 10 wound over a reel 37, and provides rails 13 and 14 (not shown) on which the gripping means 11 slide. The means 11 comprises a U-shaped saddle 21 within which the solder 10 is located above a cam 25 mounted on a pivot 24 extending between the legs of the U, and through pieces 22 and 23 (not shown) sliding in slots 18 in the member 15. A connecting-rod 28 pivoted at 27 to the cam 25 and at 29 to a trigger 8 supported at 30 on the casing and urged by a spring 35 into the inoperative positions, carries a lug 31 which in the inoperative position has clearance from the saddle 21. A spring 19 mounted on a rod 33 slidable in the guide 15 is attached at one end to the guide 15 and at the other end to a cylinder 32 sliding in the slots 18. In operation, the trigger 8 is pressed to push the rod 28 forward and rotate the cam 25 to grip the solder 10. The gripping of the solder 10 is completed when the lug 31 has moved sufficiently to engage the saddle 21. Further trigger pressure moves the saddle 21 and solder gripped therein forward until at about half the forward travel the cam 25 engages the cylinder 32 to compress the spring 19. On release of the trigger 8 the spring 19 initially prevents rotation of the cam 25 so that the solder is withdrawn during part of the return travel of the saddle 21. Finally the cam is allowed to rotate to release the solder 10 when the saddle 21 slides relative to the solder into the inoperative position. Specification 656,766 is referred to.

Title: Improved method of and apparatus for producing standard length bars for use in gauging and measuring lengths
IPC: B24B7/16
Filed: 1921-06-21
Abstract: 186,149. Brookes, A. J. C., and Imperial Trust for the Encouragement of Scientific & industrial Research. June 21, 1921. Disc apparatus.- Standard length-bars for use in gauging and measuring lengths are produced by setting the bar with its axis accurately parallel to a gravity line to the centre of the earth and lapping one end by means of a lapping-surface movable in a truly horizontal plane, and the n reversing the bar and lapping the other end. The lapping- plate having parallel surfaces rests freely on the upper surface of a table d. The table has a flat annular under surface e which is parallel to the upper surface and rests on a similar truly flat surface f of a support a. The upper surface of the table may be set truly horizontal by means of levelling-screws c, and thus, when the table is rotated, the lapping- surface moves in a truly horizontal plane; a central spigot g locates the table in relation to the support. The bar h to be lapped is supported by two spaced rings i, k carried by two collars i<1>, k' mounted for vertical or lateral adjustment, or both, on a bracket l<1> secured to a wall. The bar is held in the rings by three-point contact, one of such contacts being a frictional contact to permit rotation of the bar. The bar is set truly vertical by a clamp carrying a sensitive gravity level, which is supported on the bar, and by means of the adjusting-screws and the use of the level as a fiducial indicator. The bar is lapped until its length, as measured by the apparatus described in Specification 166,248, is correct to the required degree of accuracy. The pressure of the bar on the lap may be due to its own weight only, or may be due also to added weights. In a modification, the apparatus takes the form of a jig for use upon a bench or table.

Title: Computer-aided graphics system
IPC: G06F17/50
Filed: 1972-04-13
Abstract: 1382657 Digital processors CHEVRON RESEARCH CO 13 April 1972 [15 April 1971 19 May 1971] 17090/72 Heading G4A An axonometric layout of a pipe-line is provided as the output of a system which determines the layout and provides lists of materials, &c., required for the construction of the pipeline. The system employs a digital computer which is supplied with data which is in the form of a series of "workpoints". The workpoints, set up by the designer, identify elements which are required in the pipe-line. A workpoint defines a particular position in three dimensions relative to an associated workpoint and the workpoints are paired into overlapping sets so that the position of each is defined relative to the previous one of the series. In use a workpoint calls up data from a store to establish graphic functions dependent on, for example, a change of direction or the structural characteristics of the element to which the workpoint relates. The workpoints may also cause other information to be generated automatically; for example, if a valve is specified then automatically the mating flange is specified and consequent-dimensions are generated, no further workpoint being required. Other data fed to the computer relates to the techniques and materials to be used in the design of the pipe-line, taking account of the fluid to be handled and its temperature and pressure. Further data concerns material items numbers each related to a particular element. In operation the computer generates signals relating to the selection of elements to be used in forming the pipe-line and the true three dimensional co-ordinates of a series of workpoints related to the elements. Similar signals relating to other workpoints which can be implied from the series of workpoints (as in the case of the valve referred to above) are also generated. The system output comprises signals indicating the two-dimensional co-ordinates necessary to develop the axonometric layout as a visible display, and a list of materials and draughtsman's notes. The computer may operate to develop the best view of the pipe-line by determining the horizontal and vertical extent of the pipe-line as seen from four separate points, the view providing the largest extents being selected for display.

Patent GB-1006386-A (GB)
Title: Manufacture of pentachlorobenzene
IPC: C07C17/23
Filed: 1964-04-24
Abstract: Pentachlorobenzene is made by reacting a gaseous mixture of hexachlorobenzene and a hydrogen-containing substance at a temperature between 350 DEG  and 500 DEG  C.  Specified hydrogen-containing substances are hydrogen itself, ammonia, and hydrocarbons of up to 8 carbon atoms, e.g. methane, hexane or benzene.  The reaction is preferably effected in the absence of air or oxygen.  The reaction causes the deposition of a graphitic coating of the wall of the reaction vessel and this coating serves as a catalyst for the reaction, the velocity of which increases as the coating builds up.  The formation of the coating is promoted by increasing the surface of the reaction vessel, e.g. by a packing of graphite or metal gauge.  A part of the catalyst may be removed, when necessary, by passing air through the reaction vessel at about 300-350 DEG  C.  Examples are given of the treatment of hexachlorobenzene with hydrogen and ammonia to yield products containing pentachlorobenzene, some tetrachlorobenzene and unreacted hexachlorobenzene, from which hexachlorobenzene is removed by distillation and tetrachlorobenzene and pentachlorobenzene are then separated by crystallization from alcohol.
