Patent GB-192140-A (GB)
Abstract: 192,140. Donisthorpe, H. St. J. de A. Oct. 24, 1921. Vacuum tubes.-A helical grid, interposed between a filament cathode and an anode, is energized by passage of current, so as to produce magnetic fields which counteract the effect of mutual repulsion on the electrons emitted from the ends of the filament, and prevent the escape cf these electrons through the open ends of the anode. In one arrangement, both ends of a grid are connected to the positive terminal of a battery, and the middle point is connected through a resistance with the negative terminal, so that each half of the helix produces a magnetic field. In another arrangement, one half of the grid is wound in one direction, and the other half in the other direction, the ends of the grid being con. nected with a battery through. a resistance.

Abstract: 859,779. Washing gases. WAAGNERBIRO A.G. June 19, 1957, No. 19306/57. Drawings to Specification. Class 55 (2). [Also in Groups XIII and XXVIII] Water or a freezing solution at a temperature of about 100‹ C. below that of a fine solid or liquid particle-laden gas stream traversing a duct is trickled over sintered metal or ceramic bodies located within and extending across the duct and serves to increase the molecular concentration of the carrier gas adjacent said bodies thereby resulting in separation from the gas of particles. The cold liquid flow also removes separated particles deposited on said bodies.

Title: Process and apparatus for optimizing the penetration speed of a drilling tool driven by a motor whose torque decreases with increased speed
Inventor: GOSSELIN JEAN CHARLES
IPC: E21B44/04
Filed: 1970-04-22
Abstract: 1284149 Boring earth INSTITUT FRANCATS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 22 April 1970 [30 April 1969] 19307/70 Heading E1F An earth drill has automatic control of the weight applied to the drill bit to maintain the weight for maximum drilling speed. The drill may be driven by a down-the-hole motor 6 e.g. a hydraulic turbine on a flexible drill string, as shown, or by a rotary pipe string (Fig. 2A not shown). In the former case the weight is controlled by an endless track clamping arrangement 9 driven by a motor 10, and in the latter case, the pipe string is suspended in a derrick on a cable connected to a winch similarly driven by a motor. Followers 16, 20 monitor respectively the length of the drill string (L) and the speed of advance (Vd) at the surface, and a transducer 15 produces a signal indicating the tensile stress (T) in the drill bit. The speed of advance (Va) at the drill bit is calculated by a computer 13 from the equation: where α is a measure of the elasticity of the drill string, and #T is the increase in load during the time interval #t between successive computer operations. The computer also derives the quotient #Va/#T where #Va is the   increase in Va during the interval #t, and generates a signal on line 12 to engage or disengage the clutch 11 to maintain the ratio #Va/#T within limits near the maximum value of Va. The computer may also generate a limit speed when the motor speed or drill load reaches a predetermined safety limit, and may read out the value of the penetration speed Va at 27.

Title: Manufacture and use of wetting preparations
IPC: D06M11/38
Filed: 1931-07-06
Abstract: The wetting properties of mercerizing lyes are improved by addition of terpineol or pine oil together with a cresol or a xylenol (or mixtures thereof) and a soap-forming fatty acid or a soap.  The said substances may be added separately to the lye, or they may first be mixed together and the mixture added as such. The relative proportions taken are cresol and (or) xylenol 85-95, terpineol or pine oil at least 4, and fatty acid or soap at least about 1 per cent, and the mixture may be added to the lye to the extent of 2 per cent.  In the examples, (1) a mixture of cresylic acid and commercial xylenol is mixed with terpineol and oleic acid, and the mixture added to caustic soda mercerizing lye; (2) as in example 1, but with pine oil instead of terpineol; (3) commercial xylenol, pine oil, and oleic acid are mixed, and the mixture added to caustic soda mercerizing lye.

Abstract: 1,162,621. Welding or cutting by fusion. AIR REDUCTION CO. Inc. 24 April, 1968 [24 April, 1967], No. 19483/68. Headings B3R and B3V. [Also in Division G3] In gas-shielded pulsed arc welding or cutting, the varying arc current is obtained by periodically varying the composition of the shielding gas. The varying composition may be achieved by varying the supply of the constituents of a gas mixture, alternately connecting supplies of different gases or using a pair of concentric gas shields and intermittently cutting off the gas forming the inner shield. The arc current may be pulsed at 10 cycles/sec. for tungsten inert gas shielded arc welding or at 45 or 60 cycles/ sec. for metal inert gas shielded arc welding. The welding supply may be A.C. or D.C. of either polarity or a 3-phase supply may be used to provide a superimposed 360-cycle ripple. In consumable electrode arc welding, argon with or without 2% oxygen is fed through inlet 30 to provide an outer shield and carbon dioxide or helium is fed from a gas oscillator 38 through inlet 32 to provide an intermittent inner shield. The pulsed current may be such as to produce intermittent spray transfer.
