Title: Improvements in the manufacture of moulded bodies
Inventor: LUMBECK PETER
IPC: C01D1/44
Filed: 1967-02-10
Abstract: A moulded body of alkali-metal hydroxide is produced by compacting solid alkali-metal hydroxide at a pressure of at least 100 kg./cm.2, with concomitant shaping.  Preferably the compacting pressure is from 250 to 750 kg./cm.2 and the alkali-metal hydroxide is in the form of flakes.  It is preferred to compact the alkali-metal hydroxide in a mould, which is heated to at least 80 DEG  C. and preferably to 100-120 DEG  C., to give a smooth surface to the moulded body.  The surfaces of the tools are preferably treated with an antiadhesive agent, e.g. polytetrafluoroethylene.  Prior to compacting, binding agents, e.g. the corresponding alkali-metal salts of long-chain saturated and unsaturated fatty acids, and of homopolymerized or copolymerized unsaturated monocarboxylic or dicarboxylic acids, may be added to the alkali-metal hydroxides, as may other additives, e.g. hydrophobing agents and dyestuffs.

Title: Improvements in or relating to the hydrodealkylation of alkylated phenols
IPC: C07C37/50
Filed: 1957-02-28
Abstract: Alkylated phenols are dealkylated in the presence of a hydrogen-containing gas at elevated temperature and pressure by carrying out the reaction in the presence of more than sufficient alkali to neutralise the phenols.  Alkylated aromatic hydrocarbons present in the mixture may be dealkylated at the same time.  The reaction may be carried out at between 350 DEG  and 550 DEG  C. and at between 7 and 150 atmospheres pressure.  The alkali may be present in quantities ranging from 1,1 to 4,4 equivalents per phenolic hydroxyl and alkalies such as sodium and calcium hydroxide are preferred.  The phenolic compounds mentioned are o-cresol, cresylic acid (a mixture of isomeric cresols) and phenolic material derived from coal.  Aromatic compounds such as methyl naphthalenes, tetramethyl benzenes and ethyl toluenes may also be present with the phenols.  The process may be carried out batchwise or continuously and a flow sheet is given together with a detailed description of the continuous process.  In examples (1)-(6) o-cresol is dealkylated under various conditions using 1,1 to 4,4 equivalents of sodium hydroxide, temperatures of 400 DEG -450 DEG C. and at various hydrogen pressures and reaction times ; (7) a cresylic acid containing 92% phenols and 8% alkaryl hydrocarbons is treated with hydrogen under pressure at 460 DEG C. and in the presence of calcium oxide to yield phenol and aromatic hydrocarbons which are removed by steam stripping.

Title: Improvements in or relating to the continuous casting of materials
IPC: B22D11/06
Filed: 1952-03-17
Abstract: 736,401. Casting processes. BRENNAN, J. B. March 17, 1952, No. 6847/52. Class 83 (1). [Also in Groups V and XXIII] In a continuous-casting process a part of the strip cast is induction-heated and another cooled during its passage through the die. The metal is fed from a crucible 1, kept at a constant level by hand ladling, to a die 6. Heating and cooling coils 5, 8 respectively are set at an angle to give a tapered cooling. effect to the strip. Alternatively, multiple cooling coils of decreasing effect may be used. Rolls 9 assist in finishing and withdrawing the strip. The strip is cooled and lubricated at the exit end by molten lead passing through a porous tungsten mass 14. In a modification, the tapered cooling effect is achieved by passing the metal round a roll 10, Fig. 4, which is cooled by water jets 16 while the opposite side is cooled gradually by coils 5, 5a and 8. In a further apparatus, the strip is drawn through a die 4 by rolls 9. The end of the die may be of porous graphite, tungsten, aluminium oxide, &c., so that molten lead or other lubricant may be passed around the strip. The apparatus may be used for glass and thermoplastics. For a multiple-sided strip there may be several alternate hot and cold areas around the strip induced by lengthwise heating elements. The use of the process results in a fine-grain structure in the metal.

Title: Auxiliary device for use with sparking plugs
IPC: F02P11/04
Filed: 1920-03-06
Abstract: 168,342. Kirkham, J. March 6, 1920. S t a r t i n g , preventing unauthorized.-Spare plugs, corresponding in number to those in the engine, are separately mounted in insulated holders 1. These holders are rotatable and have contacts arranged so that the plugs therein may be either in parallel or in series with the engine plugs, may short-circuit the engine plugs or may be in neutral position. A central rod 16 carries a locking disc, the rotation of which brings a projecting portion into engagement with a pin on each holder. Adjustment of the holder is thereby prevented, and if it has been locked so that the ignition is short-circuited, the engine, is secured against unauthorized starting. In actuating the locking device the head 29 is pressed; its spindle releases rods from the locking disc and at the same time another rod projecting from the head engages the disc and allows it to be turned. When the head is released the first-mentioned rods re-engage different holes in the disc and hold it in the locking position. The withdrawal of the head 29 also allows a spring contact 32 to make electrical connection with the rod 16, the contact 32 being connected to the magneto contact-breaker. Normally the contact rests on insulation.
