Title: Improvements in or relating to ceramic dielectric materials
IPC: C04B35/626
Filed: 1964-08-19
Abstract: A dielectric material is obtained by forming a solution of (1) a hydrated oxide, alkoxide or a hydroxy-carboxylate of titanium, niobium or zirconium; (2) an aliphatic hydroxy mono- or poly-carboxylic acid; (3) a polyol which is liquid below 100 DEG  C., dissolving an oxide, hydroxide, carbonate or alkoxide of lead or an alkaline earth metal, evaporating to leave a resin intermediate and calcining to remove the organic portion of the resin. Mixtures of different component solutions can also be used to give mixed dielectrics.  Citric, lactic and glycol are the preferred acids.

Title: Tracer tangential velocity control system
IPC: B23Q35/14
Filed: 1972-07-20
Abstract: 1402616 Automatic electric control of template tracer stylus velocity GETTYS Mfg CO Inc 20 July 1972 34061/72 Heading G3N In a template tracing system the stylus velocity is controlled by co-ordinate control voltages produced by stylus deflection and these voltages are modified to make the tangential velocity (tracing speed) of the stylus equal a predetermined value. As shown, the stylus deflection signals are applied to a motor control circuit 12 to control the co-ordinate drive motors 10A, 10B in the usual way. A multiplier is included within the control circuit where the control signals are multiplied by the tangential velocity correction signal M. Tachometers 14A, 14B provide signals representing the co-ordinate velocity signals VA, VB in magnitude and these D.C. signals are modulated at a reference frequency, e.g. 1000 Hz, in modulators 17A, 17B with the output of modulator 17A phase shifted by 90 degrees. These signals V'A, VB are added at 22 to produce velocity vector V which is filtered at 23. Demodulator 24 is supplied with an A.C. signal representative of the actual deflection of the stylus P so that a D.C. signal output is produced which is proportional to the magnitude of the tangential velocity (Vt) of the stylus. This voltage is compared in comparator 27 with a signal representing the desired tracing speed to provide an error signal which after integration, by a capacitor or by a motor driven potentiometer arrangement, is used to modify the motor control signals.

Title: Process for converting methanol into a gas of high methane content
IPC: C10L3/08
Filed: 1974-08-01
Abstract: 1469140 High methane content gas METALLGESELLSCHAFT AG 1 Aug 1974 [16 Aug 1973] 34078/74 Heading C5E A gas of high methane content is produced by cracking methanol vapour in one or more stages at a pressure greater than atmospheric pressure, e.g. 5 to 100 kg./sq.cm. (absolute), and at an elevated temperature, e.g. 250‹ to 550‹ C. in contact with a methanol-cracking catalyst in the presence of steam, the weight ratio of steam to methanol in the gas mixture in contact with the catalyst being at least 0À7 : 1, and in the presence of a methane-containing gas having a higher methane concentration than a gas produced by the cracking of methanol alone, the product gas from the cracking is catalytically methanized in at least one methanization stage and part of the methanized gas is added to the feedstock to be converted as the methane-containing gas. The methane-containing gas may contain 75 to 100% by volume of methane. The weight ratio of fresh steam added from outside the system to methanol is below 4 : 1. The methanol-cracking catalyst may contain 25 to 75% by wt. of nickel; the maximum particle size of the nickel in the fresh catalyst is 300 Angstroms and the most frequent particle size is in the range 50 to 150 Angstroms; the fresh catalyst has a hydrogen absorption above 3 ml./gm. The gas produced by cracking methanol is passed through at least one methanization stage and then through a carbon dioxide scrubber, and a partial stream of the methanized gas which is substantially free of carbon dioxide is recycled to the methanol-cracking stage as the methane-containing gas. Alternatively, the methanized gas is passed through a cooler where it is directly contacted with trickling cold water to cool the gas and condense some of its water vapour, whereafter carbon dioxide is scrubbed out of the cooled gas, and a partial stream of the treated gas is saturated with water vapour by being directly contacted with water and condensate withdrawn from a sump of the cooler and is recycled to the methanol-cracking stage as the methane-containing gas.

[Classes 72 and 82 (i)] [Also in Group III] A closed metal vessel, the annular wall of which forms the secondary winding of a transformer with a closed iron path, is partly filled with an oxide of a metal or non-metal, for example iron ore, and is rotated during the heating of the charge by currents induced in the vessel wall, hydrogen being supplied to the vessel during rotation to reduce the oxide, and the resultant water vapour being conducted away. The hydrogen is supplied through the shaft supporting the vessel to a preheating pipe located in the vessel and leading to valves which are periodically immersed in the charge and are under electromagnetic control so that hydrogen is fed to the charge when the valve is immersed therein and water vapour flows to a condenser when the valve is uncovered. Hydrogen carried over to the condenser by the water vapour is returned to the furnace. In a modification, hydrogen inlets are mounted on the supporting shaft and the water vapour passes through cam-actuated valves to a dustcollecting chamber containing preheating coils for the hydrogen. The furnace forms the subject-matter of Specification 507,532, [Group XI].
