Patent GB-165422-A (GB)
Title: Improvements in fuel
IPC: C10L1/32
Filed: 1919-12-22
Abstract: In the production of fuel which is mobile and atomizable at the temperature of use and which consists of solid carbonaceous particles suspended in liquid hydrocarbon, stability of the suspension is promoted by causing the formation of a gel.  The method preferred is the addition of a larger quantity of protective agent, particularly lime-resin grease, than would be required to produce a stable liquid composite as described in Specification 149,306.  An amount adding 2 per cent or more of resin to the mixture is suitable.  Gel formation is also promoted in some cases by storage.  The carbonaceous substance is reduced until about and preferably more than 95 per cent passes through a screen of 100 mesh to the linear inch and 85 per cent through a screen of 200 mesh, and is then mixed with the liquid hydrocarbon by passage through a ball, tube, or paint mill, with or without heating; or the solid may be reduced in presence of the liquid. Suitable carbonaceous substances specified are anthracite, semi-anthracite, bituminous and semi-bituminous coals, lignites, peats, pressure still, smelting, and gas cokes and charcoals. Suitable liquids mentioned are fuel oils, pressure-still oil or tar, coal tar from coke ovens or gas works, and molasses.  One or more other measures promoting stability may also be employed, as described in Specification 149,306.

Title: Improvements relating to diazotype printing materials and processes
IPC: G03C1/62
Filed: 1950-04-03
Abstract: 682,614. Diazotype photography. KALLE & CO. AKT.-GES. April 3, 1950 [April 9, 1949], No. 8344/50. Class 98 (ii). A photo-sensitive material comprises a mono-diazo compound of a p-diamine of the benzene or naphthalene series, a non-photosensitive metallic salt and a primary or secondary amine which is free from other positive substituents; whereby, on exposure by ultraviolet light, the diazo compound may be decomposed to form a reducing agent which, when alkali is applied, produces a metallic deposit from the metallic salt, while diazo compound shielded from the ultra-violet light may, in the presence of the alkali, combine with the amine to produce an almost colourless, ultraviolet transmittant; diazo-amino or diazoimino compound. A layer of the material on a support such as paper or gelatine-coated acetate foil may thus be used to produce a positive from a negative, and such positive has particular use as a transition or master print whereby a number of diazo-type positives may be made from an original negative using ordinary diazo-type materials and with, if desired, ammonia development only. In example 1 the photo-sensitive material is made by coating a water solution containing the fluoboric acid salt of the diazo compound of p-amino-diethylaniline, citric acid, morpholine and silver nitrate on a support of the nature indicated above, and exposure of this through a negative by ultra-violet light, with ammonia development to make the transition print, and production of a positive re-print, is described. Further examples specify a variety of the coating solutions which include, as diazo compounds, the fluoboric complexes of diazotized p-amino- N : N - diethyl - meta - toluidine and pamino - diethyl - meta - toluidine; as amine, sarcosine, methyl-amino-ethane sulphonic acid, 4 - amino - 1 - methyl - benzene - 2 - sulphanilide, 1 - methyl - 2 - ethylamino - benzene - 4 - sulphonic acid, cyanamide and amino benzene; and as metal salt mercurous and thallous nitrates and silver sulphamate; and numerous other diazo compounds and amines are listed. Specifications 391,677 and 629,656 are referred to.

Abstract: 375,354. Bearings for weighing- apparatus. FEWSTER, T. H., National Physical Laboratory, Teddington, Middlesex. March 23, 1931, No. 8905. [Class 143.] In an oscillating pivot for delicate balances, of the kind in which flat springs in planes substantially radial to the axis of the pivot are arranged at angles to each other, the pivot being maintained in position by the inclined tensions in the springs and allowed to oscillate by flexure of the springs, the main spring which supports the resultant force on the pivot is connected to the pivot centrally in respect of the length thereof, and the other springs are connected to the outer portions of the pivot. The springs are preferably arranged in radial planes in three sets at 120‹; one or more of the springs is arranged at an angle to the radius to resist axial forces. The spindle A, which has eccentric extensions a for attachment to the oscillating part of the apparatus, is suspended from the bracket B by three sets of springs C, D, E, of which the main set C takes the vertical load and the auxiliary sets D, E are inclined to the radial direction to take any axial load. The spindle is cut away to its diameter at the required angles to present flat surfaces for attachment of the springs, and is further cut away to allow slight flexure of the free parts of the springs. The springs are attached to the spindle by being bent over keep plates J bolted to the spindle ; this construction allows them to be self-aligning and therefore uniformly stressed over their width. They are similarly attached to the bracket B, but the bolts attaching the springs E to the bracket are provided with eccentric bushes O to enable the system to be tightened up on assembly.
