Patent GB-837537-A (GB)
Title: Improvements in and relating to the production of acetylene
Inventor: LAHR PAUL HILLMON
IPC: C07C2/76
Filed: 1958-12-18
Abstract: Acetylene is produced by introducing a hydrocarbon charge into an elongated reaction vessel and passing a physical shock wave through the charge at supersonic velocity.  The shock may be produced by detonation or by expansion of a gas at higher pressure into the charge through a membrane which is ruptured.  In one embodiment detonation is produced in a tube separated from the reaction tube by a membrane which is ruptured by the detonation. The detonation may be produced for example from hydrogen or a hydrocarbon and oxygen.  The detonation chamber may be tapered to reduce the necessary volume, the wide end being the same diameter as the reaction tube.  Alternatively to avoid the use of a membrane, the charge and the detonation charge are flowed into a tube from opposite ends and vented through a common, central pipe, the flow of gases cut off, the exit sealed and the detonation charge detonated before the gases mix.  In a modification of this embodiment, an inert gas acting as a separating medium flows into the tube through the central pipe.  In producing the shock wave by the gas at higher pressure, the membrane may be ruptured by the pressure of the gas or by physical means.  The hydrocarbon charge may also contain oxygen, and specified charges are methane, ethane, propane, n-pentane, benzene, methane and oxygen, ethane and oxygen and methane and chlorine.  Where the shock wave is produced by expansion of a gas at higher pressure the charge may also contain argon or xenon.ALSO:Acetylene is produced by introducing a hydrocarbon charge into an elongated reaction vessel and passing a physical shock wave through the charge at supersonic velocity.

Title: Improvements in or relating to readily soluble sugar preparations
IPC: C13B50/00
Filed: 1959-12-08
Abstract: In making a sugar preparation which is readily soluble, without sitrring, in water and beverages such as tea and coffee and comprises ingredients which, in the presence of more than 8% of their dry weight of water, react to liberate a gas, an aqueous solution of sugar is intimately mixed with one or more gas-evolving substances and the mixture is dried, e.g. atomized, in a current of hot air, to form grains, which are then mixed with one or more acidic reagents. Alternatively, sugar is mixed with one or more gas-evolving substances, one or more acidic reagents and not more than 8% of water, based on the dry weight of the ingredients, and the mixture is granulated and dried, e.g. at 50 DEG  C.  The sugar preparation should, preferably, contain at least 5%, by weight, of the gas-evolving substance or substances based on its sugar content.  The amount of the acidic reagent or reagents may be at least the stoichiometric equivalent of the gas-evolving substance or substances.  Specified gas-evolving substances are: sodium bicarbonate, e.g. mixed with calcium carbonate, and sodium carbonate. Specified acidic reagents are phosphoric acid, an alkali metal pyrophosphate and a mixture of citric and tartaric acids.  The sugar preparation may comprise edible colouring matter and powdered flavouring and may be added to ice-water to form an effervescent beverage.

Abstract: 904,014. Electric selectivesignalling systems. PANELLIT Inc. Dec. 30. 1958, No. 42111/58. Class 40 (1). General.-In a monitoring system, output signals from a plurality of transducers (thermocouples) are continuously scanned at high speed by switch 6a, Fig. 2, if a sampled signal does not lie within a given range of values, an alarm 13 is operated by detector 9 and the scan is interrupted momentarily while the signal is measured and recorded on typewriter 4, Fig. 3, together with the time and the identity of the abnormal signal channel, then the high-speed scan is resumed. At predetermined intervals a complete recording scan is performed during which the following operations take place : (i) a first group of signals (1-75) is scanned at high speed by switch 6b to detect any abnormal signals, the results of the scan being stored at 17a, by relays, for example; (ii) the same group is then scanned slowly by switch 6c, each successive signal is measured and recorded on typewriter 2, Fig. 3, the corresponding stored information (i.e. normal or abnormal) being simultaneously supplied to the typewriter so that it prints in red for an abnormal signal or in black for a normal signal; (iii) a complete high-speed scan is made by switch 6a to detect and record all abnormal signals; (iv) steps (i)-(iii) are repeated for the next group (76-150) and all remaining groups (if any) by means of corresponding switches 6d, 6e and store 18a; (v) high-speed scanning is resumed by switch 6a. Measurement and recording operations.-Each thermocouple output is supplied to a selfbalancing bridge circuit 40 having output shafts 42, 44, 46 which position the wipers 51, 53, 57 of respective ten-position switches so as to represent the value of the signal in decimal code. The identity of an abnormal signal detected during a high-speed scan by switch 6a is supplied to typewriter 2 by means of a device 59, Fig. 2, which positions the wipers of tenposition switches 56a-56c, Fig. 3, so as to represent the angular position of the shaft of switch 6a in decimal code, and the time at which the abnormal signal is detected is supplied to typewriter 2 by means of a timing device 55 which drives the wipers of tenposition switches 55a-55d representing hours and minutes. The wipers of switches 55a- 55d, 56a-56c and wipers 51, 53, 57 are energized in succession of switch 58 to provide a serial train of operating signals for typewriter 2. In a recording scan, switch 88 repeatedly energizes wipers 51, 53, 57 in succession as it is stepped over contacts 1-226 in synchronism with the scan of the group of signals 1-75 or 76-150 by switch 6b or 6e respectively.

In this application the gyroscope is used as a two degree of freedom directional gyro. Alternatively the casing 10 may be transparent and marked with indicia lines for visual observation of the deviations of the element 32, and use of the gyroscope as a rate gyro.
