IPC: H03M1/10
Filed: 1967-08-01
Granted: 1968-08-09
Abstract: 1,172,830. Calibrating digital voltmeters. SOLARTRON ELECTRONIC GROUP Ltd. 26 July, 1967 [2 Aug., 1966], No. 34646/66. Heading G4H. A digital instrument 10, e.g. a voltmeter is automatically calibrated for a given value in response to a command input signal applied to a bi-stable 11 by testing the output of the instrument in a logic gate 14 to determine whether it is equal to or differs from the given value, the output of the gate 14 being used to adjust the instrument until it gives the correct output and thereupon to reset the bi-stable 11 so that the instrument is set for normal operation or a further calibration operation is initiated. As described, the given value is zero, the input terminals of the voltmeter being short-circuited and the gate 14 being set to respond when all the inputs are "0." If any of the inputs are " 1 " the inverter 15 passes a signal to gate 16 to signify that a correction is necessary. Another input is from bi-stable 11 and the third from the " adjust-command " output 25 of the voltmeter 10 through capacitor 26 and delay 17. Gate 16 passes a pulse to gates 18, 19, one of which is open according to the sign of the reading of the voltmeter. A motor 20 is controlled by the open gate to move a step in the appropriate direction adjusting potentiometer 21 to reduce the error. The meter gives a succession of command signals, one at each change of reading, until the gate 14 indicates that all the inputs are " 0." At this moment gate 23 is enabled and the next command signal resets bi-stable 11 so that normal operation can take place. Or if calibration at another value is to be made this is initiated by the resetting of bi-stable 11.

Title: Improvements in methods of working materials made from metal powder
Inventor: WHYBROW PETER JOHN LEONARD
IPC: B23K35/32
Filed: 1955-01-14
Abstract: 804,733. Casting processes; welding by pressure. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 11, 1956 [Jan. 14, 1956], No. 1183/55. Classes 83 (1) and 83 (4). In a method of working or welding metallic materials comprising metal powder particles and a non-metal constituent insoluble in the metal and present as a film on the surface of the metal particles or as particles mixed with the metal particles, or both, the material is heated to, or slightly above, the melting temperature of the metal, the temperature and heating period being governed so that collapse or excessive cracking of the material does not occur and the non-metal constituent remains substantially intact to act as a skeletal support for the heated material, the heated material then being worked or welded by pressure. An aluminium billet 3 made by cold-compacting and extrusion of aluminium flakes with an oxide coating constituting from 2-15 per cent by weight, is rapidly heated by induction in a cylinder 2 to 650‹ C., then further briefly heated to more than 660‹ C., so that the surface of the billet is slightly hotter than the remainder. A support 11 is then withdrawn and the billet forced by a ram 1 into a split die 8. Additional heating coils 12, 13 are provided at the neck of the die. For metals which shrink during solidification, a flow of material at working temperature is maintained towards the solidification front, by e.g. a composite ram, parts of which are capable of independent movement to maintain pressure on different zones of the material as it shrinks, or by a pocket of high-pressure gas generated between the ram and the material, as by means of a combustible pellet, e.g. of cordite or wax stuck to the face of the ram. In a welding process the edge portions of the members to be joined are raised to the appropriate temperature and brought together under pressure. Dies or the like may be used to maintain the shape of the welded portions. Examples using Zn plus carbon black powder or alumina, and solder plus alumina, are quoted.

Title: Improvements in or relating to Shaping or Forming Devices for Operating on a Moving Web
IPC: B65B9/06
Filed: 1967-01-10
Abstract: 1,177,241. Making bags. CLOUD MACHINE CORP. 10 Jan., 1967 [28 July, 1966], No. 1294/67. Heading B5D. [Also in Division B8] A web of material such as plastic, paper, cloth, or metal foil, is fed to a shaping or forming device, e.g. a device for folding the web along its centre line, the device being moved transversely of the web path in accordance with transverse movements of the web by the engagement of the web edges with guide means on the device so as to maintain a predetermined transverse relationship between the web and the device, i.e. so that the fold line is maintained in a predetermined position. The fold may be a U-shaped fold or a creased fold. As described, the device is employed in a machine for making packages containing, e.g. salt. The web 13 is fed from a roll 14 by feed-rollers 19-22, suitable braking means being incorporated to maintain the web under tension. The web edges are engaged by transversely-adjustable rollers 46-49 on shafts 40, 43 mounted on a frame 38 attached to and extending rearwardly of the folding device 23. The latter comprises a base-plate carried by a vertically-adjustable pivot shaft 26, and a wedge-shaped folding- head 50 tapering to a forming edge 51, mounted on the base-plate. Two approximately rectangular-sectioned blocks 61, 62 fixed to the base-plate provide edges 66, 67 adjacent to the edge 51 for guiding the folded web. A bracket 54 is screwed to the blocks 61, 62. Bolts 55, 56 attached to the folding head 50 engage slots 57, 58 in the bracket 54 to permit of vertical and longitudinal adjustment of the head. The engagement of the web edges with the rollers 46-49 causes the folding head 50 to be moved about the pivot 26 in accordance with transverse movements of the web to maintain the fold line centrally of the web. After leaving the folding device, the web 13 passes between rollers 73, 74 and around a heated seamer 76, projections 77 on which cause vertical seams to be formed in the web at spaced intervals. Rollers 83 then feed the web around a filling station 84 comprising circumferentiallyscalloped surfaces 85 and a similar number of funnel-shaped depressions 86. The pockets formed by the seams are maintained against the surfaces 85 by suction, and are opened by air streams. As each pocket passes beneath a hopper 88, a given quantity of material such as salt is released into the funnel-shaped depressions 86 and passes through openings 89 into the pockets. Subsequently the web is operated upon by a heat-sealer 91 to close the filled pockets, and by a cutter 95 for severing the separate pockets. Unfilled pockets, pockets with open tops, or a number of pockets in long lengths may be produced by disconnecting parts of the filling &c., apparatus.
