Patent GB-589292-A (GB)
Title: Improvements in and relating to the manufacture of formaldehyde
IPC: C07C45/38
Filed: 1944-08-02
Abstract: Formaldehyde is produced by reacting methanol vapour in the presence of a metal oxide catalyst with a gaseous mixture, containing not more than 10.9 per cent by volume of oxygen, in proportions which give a ratio by weight of mixed gas to methanol of from 5-14 : 1, and yield an exit gas containing at least 2 per cent by volume of oxygen.  The reaction products may be scrubbed with water, a part purged, and the remainder, e.g. 85 per cent, returned with additional methanol and oxygen-containing gas to give the necessary oxygen content.  Reaction temperatures are generally about 225-500 DEG  C.  Using molybdenum oxide promoted with vanadium oxide, the optimum is 325-400 DEG  C. Proportions of oxygen-containing gas to methanol may be 14, 10, 7 or 5 to 1.  The lower limit of the oxygen concentration is generally maintained between 2 and 5 per cent.  Mixtures of oxygen or air with inert gas such as nitrogen or boiler house gas may be used.  In continuous operation, an initial mixture of air and methanol in a ratio by weight of not less than 14 : 1 is passed over molybdenum and/or tungsten oxides promoted with vanadium or iron oxides and the scrubbed gases recycled until the oxygen content of the gases, other than methanol, is about 9 1/2 per cent by volume.  The methanol content is then increased to the desired value.  In examples, weight ratios of gas to methanol are 10, 12 and 14 : 1, inlet gases contain 7.88, 8.15 and 9 per cent oxygen, while purged and recycled gases contain 3.6, 6.4 and 5.1 per cent.  The water fed to the scrubber may be varied to yield 40-60 per cent formaldehyde solutions. Specifications 296,847, [Class 2 (iii)], and 539,488 are referred to.

Title: Improvements in poppet valves
IPC: F01L3/20
Filed: 1920-05-31
Abstract: 172,039. Brenner, L. W. May 31, 1920. Closure members, simple lift; rotating to ensure even wear; materials, special.-Relates to poppet valves, more particularly for internal-combustion engines, and consists primarily in so connecting the valve head to its spindle that during the movement of the valve in one direction the spindle rotates relatively to the head under the torsional action of the loading-spring, whilst during the movement in the opposite direction the valve head and spindle move in unison. This arrangement enables the valve to seat each time in a different angular position and thereby ensure uniform wear. For this purpose the valve member consists of a lower part 8 and an upper resilient flexed disc 10 enclosing a head 6 formed on the top of the valve spindle with upper and lower spherical surfaces of different curvature so that the valve head can tilt. The upper plate 10 may have apertures 12 so that the head 6 in the initial opening acts as a vent or balancing valve to facilitate opening. The valve member may be made of three and one-half per cent nickel steel, or of low carbon soft steel. For high temperatures in internal-combustion engines the resilient disc is made of steel alloys containing chromium or tungsten, and the stem of high carbon steel, or vanadium or chrome-vanadium steel. Reference has been directed by the Comptroller to Specification 5471/89.

Title: Improvements in or relating to x-ray apparatus
IPC: H05G1/54
Filed: 1955-05-26
Abstract: 769,063. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 26, 1955 [May 29, 1954], No. 15221/55. Class 98(1) In X-ray apparatus having a safety circuit to prevent the high voltage from being switched on in the event of a failure of' the filament current supply, the working contact of an electromagnetic relay is included in the control-circuit for high voltage and the energization of the relay is controlled by the sum of two voltages, which are approximately in phase opposition, one being a constant voltage and the other voltage varying with the filament current. As shown in Fig. 1, an auto-transformer 7 has tappings 8 whereby a variable voltage can be applied to the primary winding 6 of a high tension transformer 5, the secondary winding 4 of which is connected to the X-ray tube 1. Contacts 12, 13 of a high-voltage control relay 14 are included in the supply leads 9, 11. The autotransformer 7 also supplies the primary winding 20 of a filament transformer 19 through a fuse 22, a variable filamentcurrent resistor 21 and a variable resistor 23. A voltage proportional to the filament current is developed across the resistor 23, while a fixed voltage, approximately in phase therewith is developed across a part 24 of the winding of the transformer 7. These voltages are connected in opposition across a rectifier bridge 27. The output of the rectifier bridge is connected to the winding of a relay 26, having contacts 29 in series with the winding of relay 14. When the voltage derived from the filament current is substantially equal to the fixed voltage; relay 26 is not operated and contacts 29 are closed, so that relay 14'may be energized from a supply 16, 17 on closure of a switch 15. If desired, the rectifier bridge 27 may be omitted the voltages being connected in phase opposition to two windings of the differential relay. Alternatively, the voltage output from the rectifier bridge 27 may be applied to a switching valve such as a triode or a gas filled discharge tube. A condenser 36 may be connected in parallel with the primary winding of the filament transformer 19, in order to reduce the reactive component of its zero load current.
