Title: Improvements in the flameless reaction of gaseous hydrocarbons to form carbon monoxide and hydrogen
IPC: C01B3/40
Filed: 1956-12-21
Abstract: <PICT:0834595/III/1> In the flameless partial oxidation of a gaseous hydrocarbon, e.g. methane, optionally in the presence of water vapour and/or carbon dioxide, in two catalyst stages, a portion of the hydrocarbon being oxidized in the first stage to produce water vapour and carbon dioxide which is reacted in the second stage with the remaining gaseous hydrocarbon to produce synthesis gas, the catalyst for the first stage is platinum supported on a refractory inert granular carrier material, the platinum being in a proportion of 0.003-0.15%, preferably 0.01-0.1%.  The gas treated contains less than 30 m.g. of sulphur per normal cu.m. The second stage catalyst may be nickel supported on a refractory inert granular carrier material.  The carrier material may be magnesite, sillimanite, chamotte, or fire-concrete.  The oxidation catalyst may be prepared by impregnating a carrier with a hot or cold solution of platinum chloride and then decomposing the platinum chloride.  The oxygen for the oxidation reaction may be added as air.  Water vapour in a ratio to methane of 0.5-4:1 may be added.  An excess pressure of 0-30 atoms. may be employed. The temperature in the first stage may be 800-1400 DEG  C. and in the second stage 600-1100 DEG  C. 2000 normal cu.m. of dry synthesis gas may be produced per sq. m. of reaction surface per hour.  A final conversion of carbon monoxide to hydrogen may be effected. As shown, natural gas containing 98% methane is passed through a pipe 1, wherein it is admixed with steam from saturator 3 and pipe 7, and heatexchanger 5 to a chamber 9 where it is mixed with a mixture of air and oxygen which has passed through a pipe 2, wherein it is admixed with steam from saturator 4 and pipe 8, and heat-exchanger 6.  The gases are heated to 570 DEG  C. in the heat exchangers by exchange with the reaction product gas.  The mixed gas is passed first through a layer 11 of magnesite, then through a layer 12 of magnesite impregnated with 0.04% of platinum, and finally through a catalyst layer 13 of magnesite impregnated with nickel.

Title: Improvements in or relating to Electrical Intelligence Storage Equipment
Inventor: BRAY FREDERICK HARRY
IPC: H04Q11/04
Filed: 1967-08-24
Abstract: 1,186,416. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 24 Aug., 1967, No. 39051/67. Heading H4K. [Also in Division G4] In a data store having asscoiated read, write and processing circuitry, the latter is subjected to routine testing by: reading-out a word from a selected location in the store, storing the word in a temporary memory, processing the word, e.g. by inverting 0 and 1 bits and rewriting the modified word into the store at the originally selected location; reading-out the modified word and subjecting it to further processing whereby the word as originally read-out should be obtained, and writing this word back into the store; and finally reading-out the word once more, comparing it with the word stored in the temporary memory and then rewriting it again if all is well. The three stages of the test are performed during three successive access cycles of the store's address register. The test is applied whilst the store is in normal use but preferably just before a particular word location is required to be used. Alternatively the words can be tested successively during each word's "dead time ". More than one temporary memory together with additional logic can be used for processing the data words. Audible or visual alarms are given if a fault is found at any stage of the test. The invention is applicable to stores used in a general purpose computer (Fig. 1, not shown), to metering pulse stores in a telephone exchange where the processing circuitry consists in ADD 1 and SUBTRACT 1 logic (Fig. 2, not shown), or to the speech stores required at the intersections of highways in a PCM telephone system (Fig. 3, not shown). In the latter case testing takes three frames and the word location under test is busied against use by subscribers even if a conversation involving the use of this word location is in progress. Normally testing is not allowed to commence until the word location has been unused for a preset period and if the said period does not occur within a determined time testing of this location is abandoned and testing of the next location is commenced. The store may comprise a matrix of ferrite cores or be a thin film magnetic memory.

Title: A repetition device for setting co-ordinates of a machine tool
IPC: G05B19/06
Filed: 1963-10-03
Abstract: 1,003,375. Photo-electric position determination. WATAN-WERKE G.m.b.H. Oct. 3, 1963 [Oct. 19, 1962], No. 39078/63. Heading G1A. In a device for setting the position or positions at which it is required to stop a machine tool member performing repetitive operations the member is associated with a fixed programme carrier on which are eccentrically mounted for rotation one or more axially symmetrical pins. The machine member carries an optical system projecting a beam of light across the face of the carrier supporting the pins on to at least one pair of photo-cells arranged in a bridge circuit and giving zero output when a pin is in the beam and the member in a required position. The pins may be formed as illustrated in Fig.10 in which 7 is the part projecting from the carrier into the light beam and 24 the shank entry a suitable bore in the carrier. The knurled part 25 enables the pin to be turned for accurate positioning after which the shank may be secured by a set screw. The carrier may comprise a bar with holes to receive the pin shanks drilled at the required positions. Fig. 15a shows the optical system of one embodiment in which the light beam from source 1 is formed into a parallel beam and projected across the path of the pins 7. The two halves of the beam are then concentrated onto two photo-cells or two groups of photo-cells 34 35. In a modified optical system (Fig. 1, not shown) an image of the pin 7 is formed as a shadow on an image screen carrying the groups of photo-cells. In operation the member and optical system are moved at normal speed in a given direction until a pin is reached. It is preferred to use an extra photo-cell to detect the pin as it approaches the bridge-circuit cells. This extra cell reduces the speed of movement and prepares the control circuit to enable the drive to be stopped as soon as the bridge circuit output is reduced to a pre-set value. The illumination of the first cell obstructed is reduced and then begins to increase as that of the second cell is reduced, the output of the bridge tends towards zero as the illumination of the cells tends to equality. Before the position of equal cell illumination is reached however reduction of the output signal to a predetermined level switches off the drive. The switch off point is chosen so that the slight over-run carries the system exactly to balance point.

Title: Phosphorylated glyceride derivatives for use as emulsifying agents
Inventor: HARRIS THOMAS LANE
IPC: C07F9/10
Filed: 1962-10-18
Abstract: Viscosity-reducing emulsifying agents are prepared by subjecting an at least partially unsaturated triglyceride to glycerolysis and phosphorylation, a vacuum steam distillation being carried out between these two reactions at a temperature sufficiently high to remove the glycerol by-product, but not so high as to cause the reverse reaction to occur.  Suitable triglycerides are safflower oil, niger seed oil, ground nut oil, cocoa butter, soya oil, cottonseed oil, or rape seed oil, all of which may be unhardened or partially hardened; the preferred starting material is rape seed oil partially hardened to an Iodine Number of 70 to 80 and melting at 32 DEG  to 37 DEG  C.  Glycerolysis may be effected by refluxing under nitrogen or CO2 at atmospheric pressure and at 290 DEG  to 320 DEG  C., whereby water is expelled but glycerol returned, for about 3 hours, using more than 1 molecule of glycerol to 2 molecules of triglyceride. Catalysts such as NaOH or sodium glyceroxide may be included.  Excess glycerol may be stripped off by steam distillation at 190 DEG  to 220 DEG  C., below 2 inches absolute pressure of mercury. Phosphorylation may be effected with P2O5, or under vacuum with polyphosphoric or phosphoric acid; about 1/2 mole of P2O5 per 1 mole of glycerolysis product being used. Preferably the phosphorylated product is then neutralized, to a bromocresol purple colour change end point, with ammonia (gas or aqueous solution), ammonium carbonate, NaOH, or ethanolamine.  The product is for use as an additive to molten chocolate to reduce the viscosity, for which purpose it may first be diluted with cocoa butter, and mixed with lecithin.
