Abstract: 1283390 Welding by fusion BABCOCK & WILCOX CO 30 Oct 1969 [31 Oct 1968] 53191/69 Heading B3R In submerged-are or gas-shielded welddeposition of one or more bands of cladding 14 on a workpiece 18 using a plurality of simultaneously operative consumable electrodes, e.g. 31-36, distributed widthwise of the band and moved relatively to the workpiece, an end electrode 36 is positioned so as to lag behind a line-abreast remainder of the electrodes to improve the junction of adjacent bands by avoiding the undesirable tendency of the cladding at the edge 15A to roll over above or overhang the adjacent workpiece surface. Side-by-side or helical bands may be deposited respectively on a flat or curved or on a cylindrical workpiece. For deposition of a first band only, the electrode 31 also may be disposed in a lagging position, using a displaceable or, as shown and in Fig. 3A (not shown), replacement welding head part. For deposition of subsequent bands, preferably, for further junction improvement, the electrode 31 is operated at reverse (+) polarity whilst the electrodes 32-36 are at straight (-) polarity; and preferably, also, the electrode 31 is positioned above, or to overlap, the edge of the previously deposited band. To avoid the necessity for alternative polarity connections for the electrode 31, the first band may be deposited using electrodes 32-36 only, the electrode 31 not being fed. Either the electrodes or the workpiece may be moved and automatic indexing means may be used for lateral positioning. The electrodes 31-36 may be laterally oscillated by means 50.

Filed: 1974-12-12
Abstract: 1495716 Filtering HOLSTEIN UND KAPPERT AG 12 Dec 1974 [19 Dec 1973] 53723/74 Heading BID A filter housing (Fig. 1 not shown) is divided by a transverse tube plate, from which depend inward-flow filter elements, into an inlet space (2) and a filtrate space (1), respectively connected to pipes 5 and 10 in the circuit shown, which includes a pump 7 capable of feeding unfiltered liquid and subsequently washing liquid to space (2) at a first flow rate and a pump 12 which then circulates the washing liquid in the reverse direction, into space (1) and out of space (2) at a second: flow rate, which is preferably at least double the first. Following filtration, compressed gas is delivered to inlet space (2) displacing the unfiltered liquid back through pipe 5 while holding the filter cake, which may include filter aid, on the elements. Space (2) is depressurised, then compressed gas is fed to space (1) washing the cake from the elements by reverse flow of residual filtrate, and a valve (13) at the bottom of the housing is opened to discharge the cake from space (2). The circuit of Fig. 2 is then used to clean the elements, either with mains water or with another washing liquid which is obtained from and later returned to a storage vessel. Pump 7 first fills the housing with the washing liquid, forcing it via pipe 8', valve 15, pipe 8, valve 9 and pipe 5 into space (2), from which it flows forwards through the elements to fill space (1). Valves are switched over and pump 12 started to circulate the liquid through valve 15, pipe 8, valves 9 and 21, pipe 10, through the filter elements in the reverse direction and out of space (2) via pipe 5, valve 16, pipe 11, valves 19 and 17 and pipe 18 back to pump 12. While pump 12 is running, pump 7 may be switched off or alternatively could continue to deliver liquid to the circuit via valve 15 to further enhance the reverse flow cleaning rate. Eventually the filter is emptied and filtering resumed.

Title: Coin counting machines
IPC: G07D9/04
Filed: 1972-11-23
Abstract: 1448198 Counting coins CONTROL SYSTEMS Ltd 22 Nov 1973 [23 Nov 1972] 54186/72 Heading G4D A coin counting apparatus has an. inclined path 1 down which coins of various denominations are slid; an array of photo-electric detectors 6 arranged to be selectively obscured by coins of different sizes ; and a logic circuit (Figs. 4A+4B) arranged to increment a counter 25a-25d by increments representative of values of the coins as indicated by their size. The detectors 6 may include photo-cells 8 and light guides 7; they are illuminated by a parallel beam from source 5. Each photo-cell 8 is coupled by an inverter 14 to a NAND gate 15; the lowest denomination cell 8 is coupled to the second input of each NAND gate 15. Each gate 15 provides an output, which sets a bistable 16, only if its cell and the cell of the lowest denomination is obscured; this reduces the sensitivity of the apparatus to random shadows. One output of each bi-stable 16 is connected to a respective NAND gate 18; the opposite output of each bi-stable is connected to a second input of the NAND gate 18 of the next lowest denomination; a third input of each NAND gate 18 is energized by a bi-stable 17 when the lowest denomination cell is uncovered; thus only the highest NAND gate, i.e. that corresponding to the coin, is enabled. The NAND gates 18 are connected via coding trees to a set of NAND gates 19 arranged in groups of three per decade: the lowest group represent 1, 2 and 4 tenths of units, the next 1, 2 and 4 units, 1,2 and 4 tens of units and so on. The outputs of the groups are parallelled into lines a, b, c feeding a full adder circuit 21. The decade groups are strobed by pulses 23 on five outputs 1-5 of an eight phase clock 26, 28, 29. A counter consists of four eight bit recycling shift registers 25a-25d which are shifted continuously by the clock; the corresponding stages of the registers represent the decades of the count in 1-2-4-8 code and due to the shifting the individual decades are presented one after the other to lines 25e in phase with the clock. The new value for that decade, on lines a, b, c is added to the current total on lines 25e by the adder 21 and returned to the shift registers which thus in the course of five clock pulses accumulate the value of the coin coded in gates 19. The sixth clock pulse resets the bi-stables 16 and the eighth enables gate 17a which readies the circuit for the next coin. The coin path is such that only one coin can be presented during one complete clock cycle. The values on lines 25e are decoded at 33 and applied to seven segment displays.

A gas laser is caused to lase in a restricted region of the active medium by directing sufficient pumping energy for laser action only into the desired region. The pumping energy may be in the form of an electron or ion beam and the main body of the gas may be pumped by a second pumping source to a level just below or just above the laser threshold. In the latter case the electron beam may be used to modulate the laser output in different regions. The laser tube 10 has an electron gun 12 near one end having annular accelerating electrodes 60, 62, focussing electrodes 54, 56, 58, control electrode 53, cathode 50 and heater 46. The beam has two cross-over points 90, 92 before finally coming to a focus at 94. Instead of or as well as the focussing electrodes a focussing coil 14 is provided, and a deflection coil 16 may be supplemented or replaced by deflection plates (not shown). A high resistance coating 28 of stannous chloride on tube 10 is connected to a collection electrode 26. The helium or helium-neon active gas is pumped towards the laser threshold by a D.C. discharge between electrodes 18, 20. The effect of deflecting the electron beam is to deflect the laser output beam transmitted through one of the resonator mirrors 36, 38. The tube may have Brewster angle windows 40, 42 or curved antireflective windows having a centre of curvature at the point 94 to which the electron beam is focussed.
