Title: Improvements relating to the recovery of sulphur from gas mixtures containing hydrocarbons
IPC: C01B17/04
Filed: 1951-04-20
Abstract: Sulphur is obtained from a gas containing hydrogen sulphide, sulphur dioxide and hydrocarbons without burning or cracking the latter by passing the gas through a porous bed of contact material at 120 DEG to 160 DEG C, molten sulphur formed by the reaction between the hydrogen sulphide and the sulphur dioxide being withdrawn continuously from the bed.  When the gas to be treated, for example natural gas, petroleum refinery gas or flue gas, does not contain hydrogen sulphide and sulphur dioxide in the reaction proportions of two volumes to one volume, pure hydrogen sulphide or a sulphur dioxide-nitrogen mixture prepared by burning sulphur in air, is added as required.  The preferred contact material is granular, activated alumina or bauxite, although any porous mass, e.g. quartz chippings, capable of carrying the liquid sulphur so as to expose a large surface of the sulphur to the gas may be used.

IPC: C03B9/14
Filed: 1918-06-08
Abstract: 124,118. Sykes & Sugden, and Jackson, T. June 8, 1918. Blowing.-Relates to the type of turnover machines in which both parison and finishing moulds rotate about a central column, and consists of means for controlling the valves through which suction acts to draw the glass into the neck ring. In the arrangement shown, three turnover heads and three corresponding finishing moulds are employed. The column 1 has a chamber 8 connected by a pipe 9 to a pump or other suction apparatus. The chamber 8 communicates through three sets of pipes 10, 16 (one only being shown) with the parison moulds 5, the pipes being fitted with joints 14, 15 to allow the turnover action. The turnover axis is provided with a valve which is only open when the parison is upright, and each pipe 10 is fitted with a valve 11, the arm 20 of which is connected by a link 21 and post 22 to a. slide 6 carrying the opposite finishing mould. When the parison is being charged, the valve 11 is open, but it is closed when the slide is pushed inwards at the next station to bring the finishing mould under the turnover head. At the third station, the slide is drawn out to allow removal of the bottle &c. and thus re-opens the valve 11. Fig. 3 shows the nozzle connected with the parison mould. The air is drawn through recesses 23 in a liner 24 fitting in the nozzle 19 and surrounding the punch 25.
Patent GB-1118211-A (GB)
Title: Brake control systems
Inventor: LAWRIE WILLIAM DAVID
IPC: B60T8/32
Filed: 1965-03-05
Abstract: 1,118,211. Brake control system. GIRLING Ltd. 15 Feb., 1966 [5 March, 1965], No. 9472/65. Addition to 1,027,782. Heading F2F. [Also in Division G1] Brake applying force in a vehicle braking system is opposed by a force proportional to the deceleration of the braked wheel or wheels, the opposing force being generated by a solenoid 13 in response to an electrical signal supplied by a transducer 11 at the wheel or wheels to a deceleration sensing circuit 12. The force produced by the solenoid 13 opposes the force applied by a pedal 1 through a lever 3 and rod 5 to an air valve 7 in the vacuum circuit of a brake actuator 10. Under normal conditions of brake application the rod 5 acts as a fulcrum for the lever 3 which pushes on a rod 4 to cause a master cylinder 6 to apply fluid pressure to the brake slave-cylinders 8. Thereafter, as long as the wheels are rolling above a certain speed and the electric power and the vacuum are both working, the rod 5 is caused by lever 8 to open the valve 7 to let air into the actuator system so that it generates an hydraulic output which is fed to the slave-cylinders 8 through a safety valve 9 which also seals at the master cylinder output path. If the wheels slow below a predetermined speed or the supply voltage or the vacuum fall below predetermined levels the safety valve 9 isolates the actuator hydraulic output and opens the master cylinder output path. A switch (not shown) ensures that the transducer system is only energized when pedal 1 is depressed. In another embodiment (Fig. 3, not shown) the deceleration device (12) puts out an electrical signal which is amplified and combined with an electrical signal representing the position of the pedal (1), the pedal in this case acting against a spring (15) whereby the electrical signal also represents the brake applying force. The resultant signal obtained from a control device (16) controls the current flowing in a solenoid (18) which operates a shuttle valve (7) controlling the supply of air to the actuator (10). In an alternative pneumatic braking system (Fig. 4, not shown), the decelerationsensitive device (12) is driven mechanically from the wheel to actuate a solenoid (25) controlling a valve (24) which admits pressure air to oppose the pedal pressure applied to a main air valve (31, 32) which controls brake pressure in the system.

Title: Improved manufacture of phenol-formaldehyde resins
IPC: C08G8/28
Filed: 1925-04-09
Abstract: 259,046. Walker, E. E. April 9, 1925. Phenol-formaldehyde condensation products, which are light-coloured, are prepared by reacting on one molecular proportion of phenol with rather more than one molecular proportion of formaldehyde in the presence of an alkaline condensing agent until the viscosity lies between certain limits, and then precipitating the resin by the addition of an acid or other agent which leaves the liquid from which the precipitation occurs with a PH value between 3.2 and 7. The lower viscosity limit is such that 50 ccs. of the mixture take not leas than 2¢ minutes to pass at 25‹ C, through a standard Redwood viscometer, whilst the upper limit is such that the viscosity is not too great to prevent the separation of the aqueous layer; within these limits the resin is just short of precipitation from the solution. The hydrion concentration, after adjustment by the addition of acid or alkali and in the presence or absence of buffer substances, should be measured by the indicators bromphenol blue, methyl red or bromcresol purple. Alkaline condensing agents specified are alkali sulphite and hydroxide, and the formaldehyde employed is preferably neutral. The products are hardened by heat &c. and are then not only light in colour but also mechanically strong, resistant to water and chemical reagents, and not affected by exposure to light and air; they are useful for making or coating dentures. Examples are given of the preparation of resins from phenol, m-cresol and cresylic acid. Resins may also be made from phenol mixed with cresols, or unhardened phenol resins mav be mixed with unhardened cresol resins; modifying agents, clarifying agents, pigments, colouring matters or filling materials may be added.

Abstract: 1,201,674. Friction clutches. FICHTEL & SACHS A.G. 28 Feb., 1968 [3 March, 1967], No. 9593/68. Heading F2C. A diaphragm spring type clutch has the outer periphery of the spring 40 reacting against a clutch cover 20, an intermediate part bearing against a rib 46 of a presser plate, and the inner periphery engaged in a groove 56 of the outer race 58 of a clutch release bearing which is shifted to the left to disengage the clutch. The presser plate is connected to the cover 20 by tangential spring straps. The cover is secured by bolts 22 to a flywheel 16, and when the cover is detached from the flywheel the displacement of the presser plate under the action of the diaphragm spring is limited by the heads of bolts which are secured to the cover and pass through clearance holes in the presser plate. The limiting position is such that the inner periphery of the diaphragm spring remains engaged in the groove of the release bearing. Other forms of stop memher may be used to limit the movement of the presser plate. Assembly of the clutch, particularly is space is restricted, is thereby facilitated as the cover, presser plate, diaphragm spring and release bearing are fitted as a unit.
