Title: Improvements in or relating to electrical recording apparatus
Inventor: WATT JAMES
IPC: G01D15/06
Filed: 1952-08-15
Abstract: 711,323. Recording apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 1, 1953 [Aug. 15, 1952], No. 20625/52. Class 106 (4). [Also in Group XXXVIII] An electro-sensitive recording apparatus suitable for use in conjunction with echo sounders and other cyclically operated devices includes means for automatically changing in successive cycles of operation the effective sensitivity of the recorder, the changes of effective sensitivity being themselves repeated cyclically. It is stated that dry electro-sensitive recording paper will give a density of indication proportional to the applied current over a range of about 6db other factors being constant but that graduations in density corresponding to current variations of 14 db or more are desirable for echo sounding records. The present invention is arranged to provide a greater range than the normal 6 db and the embodiment described comprises a recorder whose sensitivity is changed between two values at the end of each cycle of operation. It is shown with reference to the graphs of Figs. 1 and 2 (not shown) that the apparent mark density can be made proportional to the applied current over a greater range by this means. A stylus. on the end of an arm 4 is rotated to pass across the slowly moving recording paper 5 once during each cycle and contacts 3 operated by cam 2 on the driving shaft are arranged to trigger the echo sounding transmitter of equivalent device when the stylus crosses the zero line on the paper. Shaft 1 drives through gearing 7, 8, a shaft 9 rotating at half speed and carrying a cam 10 which closes contacts 11 for one rotation of the stylus and opens them for the next. When closed the contacts short circuit resistor 12 in the cathode circuit of variable Á amplifying valve 14 in the echo sounding receiver. The change of gain should preferably be made equal to the tone range of the paper that is about 6 db.

Abstract: A method of heat treating high alloy tool or die steels comprises maintaining the steel at a temperature within the range in which its eutectic constituent undergoes a phase reaction in which the continuous carbide network is transformed to isolated carbide particles in the matrix and for such time that the reaction is complete before the steel is cooled.  The steel may contain from 0.5 to 2.5% C and at least one of the following elements: 0-25% W, 0-12% Mo, 0-5% V, 0-14% Cr and 0-15% Co or 1.2-2.5% C, 10-14% Cr and if desired up to 5% of each or all of W, V, Mo, or Co.  The temperature is dependent on the analysis of the steel being treated and ranges from 1230 DEG C. to 1330 DEG C.  The steel may cast and the cooling arrested at the required temperature, or the casting may be cooled and reheated to the required temperature or it may be cooled annealed and the temperature then raised to the required temperature.  After the necessary time at the required temperature the steel may be quenched, cooled slowly, hot worked, or subjected to an isothermal transformation.

Patent GB-210542-A (GB)
Abstract: 210,542. Ferguson, J. Nov. 7, 1922. Jigs; washing-apparatus with screens.-In a coal washing machine of the pulsating-plunger type, the sieves are inclined downwardly towards the plungers and water under pressure is admitted above the plungers, so as to diminish their sucking action when moving upwards and thereby increase the pulsations of the water. The particles of pyrites are then separated from the washed coal by means of a conveyer. As shown in Fig. 1, the sieves 12, 13 are inclined downwardly towards the plungers 4, 5 and carry each a feldspar bed 14 of uniform thickness and coal 14a of gradually decreasing thickness away from the plungers, so that the largest part of coal to be washed is located next the plungers. According to one Provisional Specification, to provide the plunger with antifriction means, the cylinder is lined annularly with steel, and the rod is mounted eccentrically to the plunger. Pipes 16, 17 admit water under pressure above the plungers. A regulating stopvalve 19 is supplied. The heavier incombustible material is drawn off at 15. A pyrites extractor comprises two layers of perforated plates 24, 25, the lower being of copper and of finer mesh. These are traversed by an endless chain conveyer 32 revolving on hexagonal drums 28, one of which is adjustable by means of a screw 33. The chain is formed of flat iron bars 34 having rounded ends to receive apertured links 37, and serves to convey the coal to the funnel 41. Water from nozzles 39 sprays the moving coal and washes the pyrites through the plates 24 on to the plates 25 and thence into the substructure 26. The coal residues on the plates 25 are conveyed by the chain to a shoot 42. An adjustable gatevalve 43 conveys the coal from the plates 24 either to the funnel 41 or to the plates 25, according to its position.

Title: Improvements in modified epoxy ester compostions
IPC: C09D163/00
Filed: 1964-05-22
Abstract: Coating compositions comprise an epoxy resin ester containing 30-60 weight per cent drying oil acids, and 10-50 weight per cent of an unsaturated hydrocarbon resin, the epoxy resin ester and the hydrocarbon resin having been heat-reacted to a viscosity, measured in centipoises at 50 weight per cent solids solution in xylene, which is at least four times the initial viscosity of the epoxy esterhydrocarbon resin mixture.  The viscosities are all measured at 25 DEG C.  Hydrocarbon resins specified are made by polymerizing coal-tar fractions containing indene or petroleum fractions containing cyclopentadiene or piperylene or copolymerizing such fractions with, e.g. ethylene, isobutylene and styrene, or by polymerizing a vinylcyclohexene.  The heat reaction may also be performed by mixing the epoxy resin, the drying oil acids and the hydrocarbon resin, heat reacting the epoxy resin and the acids and then raising the temperature to react the ester and the hydrocarbon resin. A sodium benzoate catalyst may be used for the esterification reaction.  The compositions may also be solvents, pigments, metallic driers, surfactants and aminoplast resins.  In comparative examples heat-bodied epoxy esters are used with and without admixed but unreacted unsaturated hydrocarbon resins and epoxy resin ester-hydrocarbon resins reaction products derived from non-oxidizing hydrocarbon resins are used.ALSO:Cold rolled steel panels are coated by spraying with a zinc welding primer containing the heat reaction product of a dehydrated castor oil acid-epoxy resin ester and a substituted vinyl cyclohexane resin, zinc dust, silica, calcium oxide, lesithin, a butylated melamine-formaldehyde resin, xylene and butanol.  The coatings are cured at 350 DEG F.
