Title: A light-resistant and weather resistant cadmium yellow pigment
IPC: C09C1/10
Filed: 1962-06-28
Abstract: A cadmium yellow pigment comprises cadmium sulphide into the lattice of which has been incorporated 1.5 to 9.0% by weight of selenium and 7.0 to 20% by weight of zinc, the percentages being based on the total weight of pigment. The pigment may be prepared by intimately mixing together powdered cadmium sulphide, zinc sulphide and cadmium sulphoselenide and heating, e.g. at 600 DEG  C.; or by treating an aqueous solution containing cadmium and zinc salts (e.g. CdSO4, Cd(NO3)2, CdCl2, ZnSO4, ZnCl2) with an alkali metal carbonate (e.g. Na2CO3) solution, and reacting the precipitated carbonates with an alkali metal (e.g. Na) sulphide solution which contains selenium, e.g. at 70 DEG C., and then filtering, washing, drying and heating the pigment; or by treating a solution containing cadmium chloride and zinc chloride directly with barium sulphide solution containing selenium.ALSO:A cadmium yellow pigment comprises cadmium sulphide into the lattice of which has been incorporated 1.5 to 9.0% by weight of selenium and 7.0 to 20% by weight of zinc, the percentages being based on the total weight of pigment.

Title: Error corrector for diphase modulation receiver
IPC: H04L1/24
Filed: 1966-06-03
Abstract: 1,115,700. Data transmission systems. RADIO CORPORATION OF AMERICA. 3 June, 1966 [22 June, 1965], No. 24938/66. Heading H4P. Errors are corrected in a digital transmission system using a code in which there is a change in polarity at the beginning of each bit. Diphase coding, i.e. coding in which there is one cycle per bit and in which the phase of one half-cycle in a bit interval is reversed to indicate a bit of a chosen state, is employed. By inspecting the polarity of the received waveform in the half-bit periods prior to and following the beginning of each bit it is determined whether an error has occurred. If an error is detected it is assumed that the half-bit having the greater amplitude is correct and the polarity of the other half-bit is reversed. The received signal D is squared up at 12 and passed to a sequence of bi-stable units 30, 34, 36 which, under the control of clock pulses F, G phased on the received signal, normally develop waveforms J, K, L, substantially similar to the squared signal. These waveforms are staggered in time. They pass as shown to first and second groups of gates, 60, 62, 64 and 40, 43, 44, fed also by delayed clock pulses. The second group develops a pulse when the half-bit polarities are alike, indicating an error. The received signal D also passes to a circuit 46, 48, 52, 50, 54 which enables one or the other of gates 56, 58 depending on which half-bit amplitude is the greater. The error-indicating pulse passes through the enabled gate and reverses the corresponding bi-stable unit, so correcting the waveforms J, K, L. The first group of gates 60, 62, 64 produces the corrected data in return to zero form.

Title: Improvements relating to the testing of gas meters

IPC: G01F25/00
Filed: 1950-10-23
Abstract: 688,072. Gas meters. WILSON GAS METERS, Ltd., G. Oct. 18,1951 [Oct. 23, 1950], No. 25733/50. Class 54. A method of testing a gas meter consists in passing through it a predetermined quantity of air or other gaseous fluid at a predetermined constant pressure and reading the meter indicator. Apparatus for carrying out the test includes a reciprocable bell 13 with its mouth immersed in a water chamber 11, adjustable stops 40, 44 tor limiting the movement of the bell and means for releasing surplus air when the bell has been fully charged. The means consists of an auxiliary bell 33 connected by a pipe 32 with the main bell and mounted in a holder 34. The auxiliary bell is loaded by weights on a platform 39 to exert a pressure of, say, 2.1 inches water gauge which is just in excess of the pressure extended by the main bell, the latter being partly balanced by a weight 16. To test a meter, a cock 29 is opened to admit compressed air to the bell 13 which rises until it engages the upper stop 40. A further supply of air now raises the pressure inside the bell and also in the pipe 32 so that the auxiliary bell is lifted until air escapes from its mouth into the holder 34 which communicates with the atmosphere. The cock 29 is now closed and excess air in the auxiliary bell passes back through the pipe 32 to the bell 13 so that the pressure within the latter corresponds to the loading on the auxiliary bell. The air is then discharged to the meter to be tested by opening a cock 31. The cock 29 may be arranged to be closed by a solenoid controlled by an electric switch actuated by the movement of the auxiliary bell. The chamber 11 is fitted with a drain cock 12 and the water level 25 is kept constant by passing the supply through a tank having an adjustable overflow pipe.

Title: A process for the production of hydrocarbons by the conversion of solid carbonaceousfuels
IPC: C10J3/46
Filed: 1951-11-02
Abstract: In the synthesis of hydrocarbons by gasification of solid carbonaceous fuels with steam to form a mixture containing CO and H2 which is catalytically converted, CO2 is removed from the exit gases of the conversion zone, indirectly heated to the temperature of gasification, e.g. 1150-1250 DEG  F., and then fed to the gasification zone.  Oxygen, equivalent, for example, to 10-15 per cent by volume of the CO2, may also be fed and is preferably preheated with the CO2 and steam to the gasification temperature. CO2 may also be removed from the synthesis gas prior to feeding said gas to the catalytic conversion zone, this CO2 also being preheated and fed to the gasification zone.  Part of the exit gases from the conversion zone may be recycled after scrubbing out the CO2.

IPC: C25B11/00
Filed: 1956-08-23
Abstract: A porous electrode for a fuel cell is made by dusting nickel powder of a particle size of 65 to 75 microns into a dish-shaped plate and sintering without pressure at a temperature between 1325 DEG C. and 1350 DEG C. for an hour in hydrogen or a mixture of hydrogen and nitrogen.  A second layer having finer pores is then produced on the first layer by painting on it a suspension in alcohol of nickel powder having a particle size of 4 to 5 microns and sintering at 1000 DEG C. for half an hour.  In an alternative method of making the first layer, nickel particles of size 7 to 9 microns or 4 to 5 microns are mixed with ammonium bicarbonate of 100-240 mesh in the proportion of 1 part by weight of the bicarbonate to 3 to 5 parts of nickel.  The mixture is pressed at 4,000 lbs. per square inch and then sintered at 1000 DEG C. to 1150 DEG C. for half an hour to 3 hours.  The Provisional Specification describes modifications of the sintering processes in one of which the temperature at which the coarser nickel particles of 65 to 75 microns are sintered is reduced to 1150 DEG C. by sintering in an atmosphere of hydrogen and nitrogen which has been passed through hydrochloric acid.
