Title: A safety valve to prevent accidents on trailing hose pipes under pressure, and subject to excessive tension
IPC: F16K17/36
Filed: 1941-03-26
Abstract: 546,917. Valves. FISHER, O., BULLOCK, J. A. BROOK, sen., G. S., and BROOK, jun., G. S. March 26, 1941, No. 4040. [Class 135] A safety cut-off valve 'for inserting in the trailing supply line to a travelling machine is adapted to close automatically in the event of the tension in the supply line increasing due to accidents preventing the supply pipe trailing. The main casing A has a threaded nipple D for attachment to the mobile machine. The other end of the casing is closed by a screwed plug E formed with a stuffing box H for the tubular valve B and provided with a coupling for attachment to the trailing supply line. The valve member has ports K and is closed at the inner end by a flanged part acted on by a spring C. Normally the ports K are above the plug E but in the event of the tension in the pipe line increasing the ports are masked by the stuffing box and the supply is cut off.

Abstract: 815,855. Mounting printing surfaces. BARTON, J. Feb. 6, 1958 [Feb. 6, 1957], No. 4102/57. Class 100(2) A mount for a printing block includes two plates 1, 2 secured together by a bolt 3 and nut 6 so as to be capable of limited movement with respect to each other while in face contact, but which can be locked in a desired relative position by the nut 6 which is located in a recess 5 in the plate 2. The recess 5 opens to one side of the plate 2 so that a key or rod' 8 can be inserted into the recess edgewise of the plate and into engagement with depression 7 on the edge of the nut 6 thereby to permit the nut to be tightened or loosened and the relative positions of the plate to be adjusted. The plate may be of wood and the printing block is fixed to plate 1. If it is desired to change the position of the block when in the printing frame, e.g. for correct registration in multi-colour printing, the nut 6 is loosened and plate 1 adjusted to the new position, the plate 2 remaining in its original position in the frame. The nut 6 is then tightened.

Title: Protective systems for alternating current circuits
IPC: H04B3/46
Filed: 1922-02-13
Abstract: 199,068. McColl, A. E., Garrard, C. C., Wilson, W., and Railing, A. H. Feb. 13, 1922. Protective arrangements for alternating-current circuits employing split conductors, of which one portion forming the main conductor surrounds another smaller portion in parallel therewith and constituting a subsidiary conductor, as described for example in Specification 29984/13, provide for balancing the conductors against one another, for protection on the percentage biassed principle for faults on either conductor. Fig. 1 shows the adaptation to the present invention of the arrangement described with reference to Fig. 3 of Specification 119,937. Current transformers C, D arer inserted with main and subsidiary conductors A, B at each end and their outputs are arranged to be equal with normal current flow. Their secondaries are so connected that their output is circulated from each through one another and through the coils E, F of a dynamometer or induction relay and through a shunting resistance R. On the occurrence of a fault on either conductor the current in one or other of the coils E, F is reversed and the point at which the reversal takes place in relation to the excess current in the faulty conductor is determined by the value of the resistance R, as described in Specification 119,937. A relay of the mechanicallybalanced type may be used instead of a dynamometer or induction type relay.

Title: Improvements in or relating to synthesis of oxygenated organic compounds
IPC: B01J27/19
Filed: 1950-02-23
Abstract: Hydrogenation of oxygenated products obtained in the first stage of the oxo-synthesis is effected in the presence of a catalyst consisting essentially of a major proportion of charcoal supporting a minor proportion of molybdenum sulphide, there having been added during the preparation of the said catalyst and prior to sulphidation a minor proportion, based on molybdenum sulphide, of a phosphorus oxide or oxy-acid.  This catalyst has high mechanical strength and sulphur-containing feed-stocks may be used.  Specified hydrogen reaction conditions are temperatures of about 400-500 DEG  F., preferably 425-500 DEG  F., pressures of about 300-3,500, preferably about 2,500-3,000 p.s.i., oxygenated product feed rates of about 0.2-1.0, preferably 0.3-1.0 v/v/hrs., and hydrogen feed rates of about 3,000-15,000, preferably about 5,000-15,000 cu. ft. per barrel of liquid feed. The catalyst may contain 5-15 per cent of molybdenum calculated as MoO3 and about 0.01-0.3, preferably about 0.03-0.1 per cent of phosphorus oxide or oxy-acid calculated as P2O5.  The preparation of the catalyst is described in Group III.  Olefines containing 6-8 carbon atoms per molecule are preferred synthesis feed stocks and metal carbonyls may be removed from the oxygenated products before hydrogenation, e.g. by the process of Specification 629,915.  Two examples illustrate the beneficial effect in activity and selectivity of the addition of the phosphorus compounds to a molybdenum sulphide on charcoal catalyst.ALSO:A catalyst used in the hydrogenation stage of the oxo synthesis essentially comprises a major proportion of charcoal supporting a minor proportion of molybdenum sulphide there having been added during its preparation and prior to sulphidation a minor proportion, based on molybdenum sulphide, of a phosphorus oxide or oxy-acid.  Preparation may be effected by impregnating activated charcoal with an aqueous solution of ammonium molybdate containing a minor proportion of phosphorus oxide or oxy-acid, preferably the pentoxide, until the desired amounts of materials are absorbed, drying, heating to about 200-400 DEG F. and sulphiding with a gaseous sulphiding agent, e.g. hydrogen sulphide or carbon disulphide, at about 700 DEG F. in the presence of hydrogen at about 3,000 p.s.i.g.  Alternatively a minor proportion of the said phosphorus compounds and molybdenum oxide are dissolved in ammonium sulphide, the charcoal impregnated and molybdenum sulphide deposited thereon by heating.  Quantities specified by weight of total catalyst are 5-15 per cent of molybdenum calculated as MoO3 and about 0.01-0.3, preferably 0.03-0.1 per cent of the phosphorus compound.

Abstract: Alkylated 3 : 6-diaminoacridinium compounds are obtained by mixing 3 : 6-diaminoacridine with an alkylating agent and heating the mixture to 90-120 DEG  C.  Dialkyl sulphates or alkyl esters of aryl sulphonic acids may be used and an inorganic salt such as sodium chloride may be added, but no solvent is needed.  The compounds appear to contain an alkyl substituent on the ring nitrogen atom and also on one of the amino groups; they have high bactericidal power and dye tanninmordanted cotton and leather orange shades.  In an example the methyl ester of p-toluene sulphonic acid is employed as alkylating agent; the product gives the reactions of an acridinium compound and when diazotized, turns to claret-red and couples with azo-components, whereas the 3 : 6-diaminoacridine gives violet diazo compounds.  It also differs from the 3 : 6-diaminomethylacridinium compound (produced by methylation and hydrolysis of the 3 : 6-diacetaminoacridine) which dyes tannin-mordanted cotton yellow shades.  The Specification as open to inspection under Sect. 91 (3) (a) relates to the above alkylation treatment applied to an aminoacridine compound of the general formula <FORM:0344627/IV/1> wherein x indicates hydrogen or an acyl group, and contains additional examples in which 3 : 6-bisacetaminoacridine is alkylated with dimethyl- and diethyl-sulphate, or with the methyl ester of p-toluene-sulphonic acid in the presence and absence of sodium chloride; this subject-matter does not appear in the Specification as accepted.
