Title: Improvements in or relating to Consumable Electrode Control Systems
IPC: H05B7/109
Filed: 1967-10-17
Abstract: 1,167,580. Automatic arc furnace control. ALLEGHENY LUDLUM STEEL CORP. Oct.17, 1967 [Oct. 17, 1966], No. 47329/67. Heading G3R. In a system for maintaining constant arc length in a consumable electrode melting furnace, first pulses are produced, dependent on some electrical characteristic of the arc, e. g. arc voltage or impedance, to which are added delayed pulses, so that if the pulses cease, which would normally cause the electrode driving motor to stop, the delayed pulses at a decreasing rate cause the electrode motion to continue downwardly, temporarily. The first pulses are passed to a circuit which generates second pulses proportional to the first pulse rate over a selected period, which first and second pulses are totalled. Means are provided for integrating the totalled pulses, also for integrating the second pulses to produce first and second signals, the difference between which controls movement of the electrode. The electrode motor may be controlled by arc voltage which is compared with a reference voltage, the error controlling a voltage to frequency converter 34 of the field effect unijunction transistor type. An alternative control, selected by a switch 40, comprises a filter 36 connected to a voltage discontinuity "hash" sensing circuit producing a pulse rate proportional to such discontinuities which may be fed to a mixer 48. The output is fed to a comparator 50 which compares pulses from the mixer 48 with those from a generator 52 - initially zero - and passes the sum through generator 52 to be added to the pulses selected by switch 40 to control the motor. On cessation of an input to mixer 48 from switch 40, the pulses from generator 52 decrease degeneratively, the run down time being longer than the expected gap in input. The delayed pulses may comprise 80% of the total.

Abstract: 474,321. Fume - confining hoods. BYRNE, E. L. W. (American Smelting & Refining Co.) Nov. 13, 1936, No. 31078. [Class 8 (ii)] [Also in Group XII] Contamination of the atmosphere by fumes &c., escaping through the open working aperture 30 of a cupel furnace is prevented by use of an exhaust hood 60 having slot like inlet apertures 84 so disposed that an upwardly flowing U- shaped curtain of air is formed in front of the working-aperture. The hood forms the lower part of a counterweight telescoping tube 61 connected to a suction duct 62, and the front and rear walls are cut away at their lower ends to provide openings 70, 71, of which the latter fits around a shield 33 projecting from the working aperture.

Title: Voltage Regulating Circuit Arrangement
IPC: H02M1/00
Filed: 1966-10-24
Abstract: 1,169,016. Automatic voltage control systems. EICHNER-ORGANISATION G.m.b.H. Oct.24, 1966 [Oct. 23, 1965], No.47729/66. Heading G3R. In an automatic voltage control system wherein D.C. at terminals 3, 4 is normally maintained at a predetermined value by intermittent operation of a switch 11 to charge a capacitor 12 from a transformer-rectifier circuit 5, 7, 8, the comparator 14 controlling the switch 11 also controls a silicon controlled rectifier 17 so that if the voltage of capacitor 12 falls considerably below the predetermined value closure of switch 11 is prevented and the capacitor is re-charged through the rectifier 17. The switch 11 is thus protected from excess current surges and the rectifier 17 is maintained non-conductive during normal voltage variations around the predetermined value. The member 11 may be a semi-conductor switch such as a transistor.

Abstract: 1,182,949. Fluid fuel burners. BRITISH PETROLEUM CO. Ltd. 13 Dec., 1968 [24 Oct., 1967], No. 48283/67. Heading F4T. A burner for fluid fuels comprises a ceramic block pierced by air passages 10 for conveying combustion air to a combustion zone, and traversed by a system of interconnected fuel channels 11, which pass between the air passages and, during the use of the burner, convey fuel into the combustion zone. As shown, the fuel channels 11 have a linear configuration and comprise two sets, the channels of each set being mutually parallel and the two sets intersecting to give, in plan view, a pattern of squares. As shown in Figure 2, the fuel is supplied by a pipe from below the channels and, in the case of liquid fuel, the channels are open to the combustion zone so that, in use, heat from the combustion zone vaporises fuel into this zone. In the embodiment employing gaseous fuel, Fig. 6, the fuel channels 11 are separated from the combustion zone by a partition 12 containing ducts 13.

Title: Barstock heading and trimming method and machine
Inventor: JOUANNET FRANK LIONEL
IPC: B21K1/44
Filed: 1966-11-01
Abstract: 1,122,726. Heading; shearing. AUTO BOLT & NUT CO. 1 Nov., 1966, No. 48961/66. Headings B3H and B3W.  In the manufacture of headed products with polygonal heads, workpieces W of bar stock are gripped between jaws 52, 53, headed to provide fillister heads and, whilst the workpiece is still gripped, the heads are sheared to polygonal shape. The operation is performed cold. Stock workpieces W are fed between adjustable guide rails 56, 57, to transfer mechanism 60, 61, 62 which moves the bottom workpiece transversely to gripping fingers (82), Fig. 4 (not shown), mounted on a vertical slide 87. The transfer mechanism is actuated by linkage 69-72 from a cam 13 on shaft 10, and the vertical slide 87 is actuated by adjustable linkage 91, 93, 94 from a cam 17 on shaft 10. The latter is driven through gearing 11 from the main crank-shaft 5 which operates the header slide 21. The gripping fingers (82) hold the workpiece W whilst it is positioned axially by stops (101), (102), on a locating mechanism (96), Fig. 5 (not shown), actuated through linkage 97 by a cam 15. Workpiece W is then moved downwardly between the fixed jaw 52 and movable jaw 53 actuated through linkage 54 and a toggle mechanism from cam 14. Header slide 21 carries a vertically slidable tool holder 25 actuated through linkage 31-34 from cam 16. Three tools (26), (27), (28), Fig. 1 (not shown), mounted on the tool-holder 25 perform successive operations on the workpiece whilst it is gripped between the jaws 52, 53. The tool holder is locked vertically during the working stroke by a wedge mechanism 49 actuated through linkage 45-48 by fixed axial cam 44. Tool (26) first upsets a conical head (109), Fig. 6 (not shown); tool (27) further upsets the head into fillister shape (110), Fig. 7 (not shown), and shearing die (28) then shapes the head into hexagonal form, Fig. 8 (not shown). This operation produces flash (120) on the underside of the head. This flash is removed by slightly releasing jaw 53 and knocking the workpiece forwardly into the die cavity of die (28), Fig. 9 (not shown), by a kicker bar 125 actuated from the cam-shaft 10. The gripping jaws close whilst the head is retracted and then open to release the workpiece on to a conveyer 130.

Abstract: 1492887 Improving wear-resistance of offset plates CIBA-GEIGY AG 28 Nov 1975  [4 Dec 1974] 48973/75 Heading G2M Offset printing plates, especially when the image is formed by a silver complex diffusion process on to a metal plate, are provided with a hydrophobic lacquer in the printing areas by the use of an ethylenically unsaturated photopolymerizable monomer and/or prepolymer in combination with a photo-initiator on the printing areas which is then exposed to actinic irradiation. The polymerizer producer provides increased wear resistance for the image areas. Either prior to, or together with, the application of the photopolymer, a hydrophilic colloid, e.g. gum arabic, and a non- photopolymerizable hydrophobic agent, e.g. a mercapto compound are also applied over the entire imaged plate. Many examples of photopolymerizing systems are provided, preferred components being acrylic compounds e.g. acrylic or methacrylic acids or esters, pentaerythritol trisacrylate and tris (methylol) propane trisacrylate. The lacquer is applied with a sponge or cotton wool pad, any present on non-printing areas or the excess on printing areas being wiped away with absorbent material prior to exposure of the plate overall to e. g. U.V. radiation.

In the embodiment described the component sensed is oxygen and additional air is added when serially connected switches 64, 66 are closed. One switch is responsive to low vehicle speed and the other to a closed condition of the throttle. When both switches are closed the electromagnetic valve 58 operates to connect chamber 52 to the inlet manifold so that the vacuum can cause valve 40 to open and thus admit air, through one way check valve 70, to the exhaust passage 22. When the engine is operating under load the chamber 52 is connected to atmosphere so that spring 54 will close the valve 40.
