Title: Hard surfacing material
IPC: C22C29/00
Filed: 1962-02-20
Abstract: A hard surfacing material comprises particles of cast or cemented hard metal carbide having a major dimension between 0.045 and 0.400 inch bonded together by a matrix metal which melts between 1550  DEG F. and 2400  DEG F. and below the melting point of any cementing metal, wherein precipitated crystals of a hard metal carbide are substantially homogeneously distributed throughout the matrix metal. The particles and the precipitated crystals may be of tungsten carbide with or without small proportions of Ti, Ta or Nb carbides or diamond and the matrix metal may be a copper alloy such as a copper-nickel-tin alloy or an iron-nickel alloy.  The material may be made by dissolving finely divided carbide powder in the matrix metal and then infiltrating the carbide particles or the carbide powder may be mixed with the particles and then infiltrated with the matrix metal.  In the latter method 5-35% of powdered nickel is preferably added to the powdered carbide to promote wetting and some tungsten powder, to increase strength and hardness, may also be added.  The hard surfacing material may be used for drill bits.

Title: Improvements in or relating to mercury vapour lamps
IPC: H01J13/00
Filed: 1927-03-10
Abstract: 292,215. Aimer, G. C. March 10, 1927. Low-pressure metallic-vapour apparatus. - In mercury-vapour lamps of the type in which a mercury column between two electrodes is caused to strike an arc by the delivery of gas from a gas reservoir to a bent or constricted portion of the arc tube connecting the anode and cathode, the reservoir being heated by an electric heater in circuit with the lamp and short-circuited by the rise of mercury in a reservoir after the arc is struck, the reservoir is located adjacent the cathode and the heater is connected to the cathode and is short-circuited by the rise of the mercury in the cathode chamber or in a reservoir connected thereto. The reservoir may comprise a closed container filled with inert gas or a substance such as spongy platinum or palladium occluding inert gas which may be driven off by passing electric current through the platinum. A gas reservoir 35, Figs. 1 and 2, may be located at the side of an expansion chamber 43 near the cathode container 21 and may be connected by a passage 59 to a constriction 27 in the arc tube 25 nearer the cathode 21 than the anode. The reservoir 35 contains a heating coil 37 in series between the circuit lead 49 and a lead 31 to the cathode, the coil 37 expanding the gas and driving it through the passage 59 when the lamp circuit is closed and being short-circuited, when the arc starts, by mercury from the cathode passing up the capillary tube 41 into contact with a lead 45. The level of the mercury before the lamp is in use is shown at 75, Fig. 1, the remainder of the tube being filled with inert gas at less than atmospheric pressure An expansion chamber 63 with a diaphragm 67 is arranged at the anode. In a lamp for alternating current, a single cathode with the associated parts 27, 37, 43, 59 is associated with two arc tubes 25 and two anode reservoirs extending at rightangles from the sides of the tubes 25, the chambers 63 of the anodes being connected at the top by a pressure-equalizing tube. To prevent shortcircuiting the anodes, the junction of the arc tubes with the part 27 is provided with a web 87, Fig. 9. The web 87 at its lowest point and the orifice 89 into the part 27 are above the mercury level 75 but the orifice 89 has a channel 91 at one side of the web 87 below the level 75 so that, when the lamp is inoperative, the cathode is connected through the mercury to one anode and not to the other. The Provisional Specification describes lamps for polyphase current with a number of anodes corresponding to the number of phases and anodes of tungsten or other metal, also lamps in which the part 27 is at the level of the mercury in the cathode chamber and the gas reservoir is connected by a passage to the gas chamber.

Patent GB-726987-A (GB)
Title: Carboxylic acid derivatives
IPC: A61K49/04
Filed: 1953-03-12
Abstract: The invention comprises compounds of the formula <FORM:0726987/IV (b)/1> wherein R is hydrogen or a lower alkyl group having 1 or 2 carbon atoms, and non-toxic salts of such a compound.  Such compounds are obtained by heating a compound having the formula <FORM:0726987/IV (b)/2> in acid solution with an excess of iodine monochloride.  Salts mentioned are those of inorganic bases such as sodium, potassium or ammonium hydroxide and organic bases such as methylamine, ethylamine, and mono-, di-, and triethanolamines.  Such bases neutralize the carboxylic group, and the strong inorganic bases, in sufficient quantity, also neutralize the phenolic group, giving a di-salt.  The iodination may be effected in dilute acid medium, e.g. hydrochloric or acetic acid.  The m-hydroxyphenylalkanoic acid can be prepared by condensing m-hydroxybenzaldehyde, an acid anhydride (RCH2CO)2O and a salt of the acid RCH2COOH to produce a substituted cinnamic acid, m-HOC6H4CH=C(R)COOH followed by reduction of the double bond catalytically or with sodium amalgam.  The products are used as cholecystographic agents.  In examples: (1) m-hydroxybenzaldehyde, sodium acetate and acetic anhydride are reacted to give m-hydroxycinnamic acid which is reduced with sodium amalgam to b -(m-hydroxyphenyl)-propionic acid and the latter on iodination is converted to b  - (2,4,6 - triiodo - 3 - hydroxyphenyl)-propionic acid.  Similarly prepared are (2) a -methyl - b  - (2,4,6-triiodo - 3 - hydroxyphenyl)-propionic acid (a  - methyl - m - hydroxycinnamic acid and a -methyl-b -(m-hydroxyphenyl)-propionic acid being intermediates), and (3) a -ethyl-b -(2,4,6-triido-3-hydroxyphenyl) propionic acid (a -ethyl-m-hydroxycinnamic acid and a  - ethyl - a  - (m - hydroxyphenyl) - propionic acid being intermediates).

Abstract: 996,654. Spray coating apparatus. ATLAS COPCO A.B. Feb. 20, 1964 [March 11, 1963], No. 7085/64. Heading B2B. A high pressure spray-coating gun comprises a body 11, a valve-operating trigger 12 and a spray nozzle 35 and is provided with an internal chamber 24, Fig. 2 (not shown) to which high pressure coating liquid is supplied through a connection 29 and from which the liquid may escape through an orifice 23 upon the opening of a valve member 47. The valve member 47 seals the orifice 23 under pressure of spring 43 and is connected by a slender steel wire or stem 46 to a head 51 slidably mounted in a bore 15 in the body 11. A sleeve member 49 likewise slidably mounted in the bore 15 and normally spaced by pressure of spring 55 from the head 51 transmits movement of the trigger to the head 51 and thus operates the valve 47. Movement of the sleeve 49 is limited by means of an encircling ring 60, which, cooperating with grooves 62, 63 in the sleeve 49 also provides means to lock the valve in the open or closed positions. The liquid passing through the orifice 23 strikes a jet-spoiling member 211, Fig. 2 (not shown), before passing through two radially offset but converging passages towards the spray nozzle so that danger of a high velocity jet issuing directly from the gun is removed. The flat nature of the valve 47 and valve seat ensure that full flow is attained almost instantly on opening, thus eliminating danger of splash marks during opening or closing.

Abstract: 888,394. Controlling nuclear reactors. GENERAL ELECTRIC CO. Ltd. March 2, 1960 [March 2, 1959], No. 7242/59. Class 39(4) Shut-down rods of a reactor are supported by electromagnets with three windings, two of which must be de-energised before a rod can be released; this prevents shut-down due to electrical faults. The Figure shows electromagnet 1 with coils 2, each coil being in series with coils in two other electromagnets. Each series of coils is energised through a magnetic amplifier 3 by one phase of one of three three-phase supplies. A reactor fault will de-energise contactors 14, 15, 16 and cut off the current supply to the coils 2; failure of one contactor to open would still allow the rods to be released, but failure of one power supply would not cause release.
