Abstract: 1,077,935. Waste reducing by arrangement of blanks in sheets. GLAVERBEL. July 14, 1964 [July 15, 1963], No. 28988/64. Heading B3A. [Also in Divisions B4 and G4] Blank sheets of glass, metal, plastic, paper etc., are cut to various required sizes with a minimum waste of material, the position of each cut being determined by linear programming of a computer. The quantities of waste material are compared for various cutting procedures of longitudinal and transverse cuts of the blank and off-cut pieces, and the procedure with the minimum waste is chosen. Various procedures are described as follows:- (a) Geometric procedure.-The length and width of each required size is graphically represented at points P, Fig. 4, on a blank S 1 . Further points A, A 2  represent resultant offcuts after initial longitudinal or transverse cuts from which smaller sizes K n  (Fig. 2, not shown) may be cut by further longitudinal and/or transverse cuts. By programming the fulfilment of an order for required larger sizes by all the alternative cutting procedures, the procedure producing the greatest number of smaller required sizes may be selected. (b) Arithmetic procedure.-After programming alternative off-cut sizes and numbers from initial longitudinal and/or transverse cuts the resultant summed lengths of strips of off-cuts placed end-to-end are compared with the summed lengths of strips of required sizes having at least one dimension near to the width of the off-cut strips. Procedures producing the greatest number of smaller required sizes are then selected. The method may also be used to determine the most suitable initial blank dimensions to cut from continuous strip material to meet an order book of required sizes to be cut from the blanks.

Abstract: 392,438. Power meters ; phasedifference measurements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Mead, M. S. ; 1410, Regent Street, Schenectady, New York, U.S.A.) Oct. 17, 1932, No. 29019. Convention date, Oct. 16, 1931. [Class 37.] The product of two quantities is measured by applying a potential proportional to one quantity to the control grid'of a four-electrode valve and a potential proportional to the other quantity to the screen grid, the screen grid being so biased as to maintain a linear relationship between variations in screen grid voltage and mutual conductance. Under these conditions the plate current is proportional to the instantaneous product of the quantities to be measured. As shown applied to a wattmeter, the load 27 to be measured is connected in series with a current shunt 28 in a high-frequency circuit. In shunt with the load 27 is a voltage divider 29. Across the resistance 28 is the primary winding 30 of a current transformer 31, the secondary winding 32 of which is connected to the control grids 18, 19 of a pair of fourelectrode valves 11, 12 in push-pull connection. A tapping 34 on the voltage divider 29 is connected to the screen grids 20, 21. The anodes 16, 17 are connected to the ends of a resistance 22, the centre point 25 of which is connected through the plate battery 23 to the common terminal 24 of the cathodes 13, 14. Across the resistance 22 is connected a direct-current galvanometer 26, the indications of which are proportional to the product of the voltages e<1>, e2, i.e. to the true power. An alternating- current instrument, a relay, or an oscillograph may be employed instead of the galvanometer 26. By adjusting the grid voltages to a certain value for each reading, the direct-current galvanometer may be calibrated to read phaseangle instead of power. If the galvanometer 26 is replaced by an alternating-current instrument, its indications are proportional to the apparent power or volt-amperes consumed by the load 27. If the resistance shunt 28 is replaced by an inductive shunt, the galvanometer 26 will indicate the reactive component of the apparent power.

Abstract: 944,859. Type-bar-making machines. E. FELTHAM. Aug. 11, 1961, No. 29157/61. Heading B6W. Moulds.-A slug-casting mould comprises a body C and a cap B which is vertically movable in relation to the body. A number of sections A are mounted on the cap so as to be vertically movable in relation thereto and are spring- biased into engagement with the cap. The segments have lugs at the casting end which when aligned correspond to the lip on an orthodox mould cap. Length of line is obtained by a laterally adjustable ledge in the first elevator which, descending on to the lugs, depresses the required number of sections so that they make contact with the opposite casting face of the mould. Wedges on the first elevator engage correspondingly shaped recesses D on the cap B as the mould wheel advances so as to regulate the cap and those sections A not engaged by the adjustable ledge in relation to the body C; in this way the thickness of the slug can be controlled. The end member E of the mould is mounted on the body C for lateral movement towards and away therefrom and is spring- biased away from the body to allow free movement of the sections; it is locked against the segments before casting by means of a further wedge on the elevator engaging a correspondingly shaped recess F in the end member E.

Title: Method of and apparatus for electrically treating workpieces by means of an electrode
IPC: B23H7/28
Filed: 1961-08-26
Abstract: In a spark or arc erosion or deposition process, or an electrolytic machining or deposition process, an electrode 3 is used having the general shape 4 of the region 2 to be treated, and which is movable transversely into positions such as 4a, 4b during the process.  This enables, in the case of electro-erosion, a single electrode to be used for coarse and final shaping using sparks of differing intensity.  The invention is applicable to the formation of internal or external shapes, Fig. 2 (not shown), and for completely piercing a workpiece or forming a recess therein. In an apparatus for performing the process, Fig. 4, the elctrode holder 18 is mounted for transverse adjustment within a carrier 15c by eight micrometer screws P1-P8 which permit movement in eight radial directions, Fig. 3 (not shown). The carrier is mounted on the feed head of a spark erosion machine. In another embodiment, Fig. 7, the electrode holder 32 is mounted on a carrier 31, secured to the feed head, through two shaft assemblies 38, 40 and 39, 41 respectively.  These assemblies permit eccentric adjustment of the holder 32 on tis carrier by a micrometer screw 45 and are interconnected by toother gearing 38a, 42, 39a.  Eccentric adjustment is set by a gauge inserted between surfaces 67a, 68a. After adjustment the shafts 38, 39 are rotated by a motor 52, Fig. 8 (not shown), which provides an orbital movement for the electrode. In a modification, Fig. 12, the elctrode holder 111 is centred within its carrier sleeve 109 by sets of springs 130, 131, Fig. 13 (not shown), but can be moved transversely along guide balls 110 by an eccentric adjusting screw 119 in a drive shaft 105, 114.  The screw 119 has a <PICT:1002802/C6-C7/1> <PICT:1002802/C6-C7/2> <PICT:1002802/C6-C7/3> <PICT:1002802/C6-C7/4> differential thread 119a, 119b, Fig. 14 (not shown), to provide accurate adjustment. When shaft 105 is rotated by a motor 102, the holder 111 has an orbital movement.  The feed movement may be performed simultaneously with the transverse movement, Fig. 16 (not shown), or the electrode may have a feed movement only whilst workpiece is moved transversely by one or more adjustment devices K, K1, Fig. 17 (not shown).  The apparatus does not refer to the application of electrolytes.
