Title: Improvements in the manufacture and production of valuable liquid products by the destructive hydrogenation of coal, tars, mineral oils and the like
IPC: C10G1/00
Filed: 1927-06-27
Abstract: 273,712. I. G. Farbenindustrie Akt.- Ges. June 29, 1926, [Convention date]. Hydrogenation, destructive.-Low boiling point oils are obtained from coals, oils, tars, bitumens &c. by first heating them under pressure of hydrogen or gases containing hydrogen and of catalysts which assist cracking and then heating the products produced with catalyst that assist hydrogenation. The catalyst used for the cracking reaction include elements of the 3rd and 4th groups, copper-iron mixtures, activated charcoals, hydrosilicates and silica. while those used for hydrogenation include cobalt, molybdenum, and tungsten. Brown coal-tar oil is heated in an aluminium lined reaction vessel in a counter current of hydrogen under 200 atmospheres pressure at 450‹ C. in the presence of active charcoal. The vapours produced are passed over a cobalt catalyst and a product containing 90 per cent benzine is obtained. Specification 272,194 is referred to.

Title: Improvements in or relating to materials having an asbestos fibre base
IPC: C04B28/26
Filed: 1964-04-27
Abstract: Materials such as paper or board have an asbestos-fibre base with silica distributed throughout the mass.  The superficial portions of the silica are amorphous and afford mechanical strength and imperviousness to water, and the remainder of the silica comprises hydrated silica with or without sodium silicate and forms a bond between the amorphous silica and each fibre and also among the fibres.  They may be made by impregnating an asbestos paper or board with a solution of sodium silicate in water, drying it, immersing it in a solution of ammonium chloride, and heating.  In an alternative method, asbestos fibre is slurried in a aqueous solution of sodium silicate, the slurry is formed to a desired shape, dried, and then treated with ammonium chloride and heated, as above.  The sheet may be corrugated before or after the treatment, and may be further waterproofed by immersion in a solution of bitumen in petroleum spirit.

Title: Improvements in or relating to methods and apparatus for converting small unidirectional e.m.f.'s into related alternating quantities
Inventor: AUGHTIE FRANK
IPC: G01R19/18
Filed: 1956-06-07
Abstract: 811,657. Oscillating motor generators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 30, 1957 [June 7, 1956], No. 17699/56. Class 35. An alternating E.M.F. is obtained from a unidirectional E.M.F. by applying the latter to a conductor which vibrates in an alternating field, and taking off the induced E.M.F. This E.M.F. may be induced in a unidirectional field separated from or superimposed upon the alternating field, or it may be of double frequency as induced in the alternating field. The conductor may be a bifilar wire 1 tensioned by spring 2 vibrating in the magnetic field of core 3 carrying coils 4, energized by A.C. The supply may be 50 cps. when the wire is damped mechanically or electrically, or from an oscillator when resonance is obtained between the natural frequency of the wire and the frequency of the field by control of oscillator frequency and wire tension. This control may be automatic, departure from resonance being detected by change in phase between E.M.F. induced in the wire and the field. Alternatively, the oscillator may comprise an oscillating wire similar to wire 1. To keep the proportionality of the device constant the damping may be mainly electromagnetic, or made as small as possible when the apparatus is used in a selfbalancing negative-feedback circuit. The D.C. input and A.C. output may be separated by filters, or by the arrangement of Fig. 3. Two wires W1, W2 vibrate in magnetic fields F1, F2 in phase quadrature so that when the D.C. is applied similarly to them the A.C. outputs are in opposition and are obtained at terminals A.C. through resistors Rl, R2. To avoid the losses in the resistors four similar wires may be used in bridge connection (Fig. 4, not shown).

Abstract: 953,718. Hydraulic apparatus. BWG BERGWERK-UND WALZWERK-MASCHINENBAU G.m.b.H. May 17, 1961, No. 17971/61. Heading F1P. [Also in Division F2] A hydraulic system for the actuation of hydraulic piston-and-cylinder devices 5 in brakes, circuit breakers, setting devices and the like, comprises a continuously-operable pump 2 for supplying fluid to the device, a cut-off valve 4 which, when the pressure liquid to the device reaches a predetermined pressure, changes the pump over to work within a circuit substantially without pressure, and a by-pass valve 6 which is closed by pressure from a resistance valve 3 upstream of the cut-off valve to prevent return flow of fluid from the device. The cut-off valve has a spool 9 which, when the pressure supplied to the device reaches the predetermined value, moves against a spring 10 to connect the supply from the pump through passages 11, 12 to a line 13 leading to a reservoir 8, a one-way valve in the spool 9 preventing flow from the device 5 through the valve 4. The resistance valve 3 provides a low pressure in a line 14 to move a spool 15 of the by-pass valve 6 to close a passage 16 and maintain the pressure supplied to the device. When the pump is stopped, the pressure in the device moves the spool 15 to the left to open the passage 16 so that fluid from the device is returned to the reservoir; a throttle 7 may control the rate of flow to the reservoir. As applied to a brake, the pressure from the pump supplied to the device 5 holds the blocks of the brake lifted from the disc when the pump is operative and springs or weights act to apply the blocks to the disc when the pump is inoperative. All the valves may be disposed in a common housing.
