Filed: 1974-02-28
Abstract: 1442494 Shock absorbing devices COMMISSARIAT A L'ENERGIE ATOMIQUE 28 Feb 1974 [6 March 1973] 9039/74 Heading F2E A mechanical shock-absorbing device (e.g. for use in a nuclear reactor) is constituted by a plate of constant thickness pierced by circular orifices 14 spaced at uniform intervals, whereby the cross-sectional area of plate material available to absorb shock energy along any line parallel to the direction in which the load is applied is substantially constant. In the embodiment of Figs. 4, 5, the plate is a cylindrical ring 8 and the orifices are uniformly spaced on circles 16 of the ring. A top section plane 10 receives an object at the end of a free fall thereof and a plane 12 bears on the support to be protected against the object. In the direction of the generator lines, e.g. # 1 , # 2  of the cylinder there is a substantially constant quantity of empty space along all the generator lines or, put the other way, there is a constant quantity of material along each generator line. In the embodiment of Fig. 6 the plate 20 is flat and rectangular, and the force is applied to top edge 22. The holes 14 have substantially the same "length" in the vertical directions parallel to #. In a further embodiment the device is in the shape of an annular ring, whose external edge may, for example, be inserted in a stationary support while the bore of the ring is intended to receive the falling object for damping the falling motion thereof. There is the same quantity of material along each of the radii of the ring A number of devices may be used in series or parallel. The device may be made of mild steels, austenitic stainless steels, or annealed copper, silver, aluminium.
Patent GB-435200-A (GB)
Title: Improvements in the manufacture and production of trimethylamine
Filed: 1934-03-23
Abstract: Trimethylamine is recovered from mixtures containing it and a substantial amount of ammonia by adjusting the basicity of the mixture to effect incomplete neutralization, by addition of acid or alkali according as the free bases or their salts are present, and separating the trimethylamine, e.g. by fractional distillation under pressure.  It is preferred to adjust the conditions so that not all the ammonia is converted into its salt the bulk of the trimethylamine then remaining uncombined, the separation of the remaining ammonia being effected by the distillation.  By employing larger amounts of acid it may be arranged that the noncombined portion consists almost entirely of trimethylamine but in this case a proportion of the trimethylamine salt is also formed.  When operating according to the first and preferred method an azeotropic mixture of ammonia and trimethylamine distils over first which is further worked up by partial neutralization. Suitable acids for neutralization of a mixture of the bases are hydrochloric, hydrobromic, sulphuric, phosphoric, dodecane sulphonic and benzene sulphonic acids and carbon dioxide.  The treatment of the bases with acids may be effected by passing the gaseous bases into the acid, e.g. in a continuous manner in a trickling tower.  If a tower is employed an acidified concentrated solution of the ammonium salt of the acid used is passed in the hot state down the tower, part of the resulting solution being worked up and the rest recirculated in the tower with addition of fresh acid.  Examples describe the separation of the bases with the use of sulphuric acid and carbondioxide.  In the latter case calcium sulphate is placed in the autoclave in which the reaction is conducted and carbon dioxide is pumped into an amount almost sufficient to convert the calcium sulphate into carbonate.

Title: A process for the removal of carbon monoxide from mixtures thereof with hydrogen
IPC: C01B32/40
Filed: 1939-03-23
Abstract: 525,803. Separating mixtures of gases. AMERICAN MAGNESIUM METALS CORPORATION. March 23, 1939, No. 9206. Convention date, May 7, 1938. [Class 1 (i)] The removal of carbon monoxide from mixtures thereof with hydrogen is effected by its selective adsorption on active charcoal at low temperatures, leaving the unbound component one or more fractions enriched with hydrogen, containing for example 1 to 2 per cent. of carbon monoxide, through the saturation of the adsorptive charcoal being stopped well b efore the adsorption equilibrium is reached; the adsorbed gases are removed by a reduction of pressure releasing one or more fractions enriched in carbon monoxide. Absorbates still retained, for example water, are removed by heating and suction. The gaseous starting mixture in the gas holder 1 is pressed into a cooler 4 by means of a blower 3 and cooled to -50C., and then passed into an adsorption chamber 6 also at -50C. The unbound purified hydrogen passes through a conduit 7 into a gasometer 9. After a few minutes the starting mixture is directed into a second adsorption chamber whilst the adsorped gases in the first are sucked off by a pump 11 ; the first fraction obtained at pressures above 100 mms. is passed into the starting mixture via a conduit 13 and the subsequent gases are passed into a gasholder 16 by the conduit 14, and thence compressed into a converter 20 by a compressor 18, where the carbon monoxide is oxidized to carbon dioxide which is washed out. Whereupon the residual gases pass out of a pressure vessel 22 through a conduit 21 to the place of use. Specification 365,092 and U.S.A. Specification 1,896,916 are referred to.

Title: Improvements relating to lubricating systems
Inventor: ARMER CYRIL
IPC: F01D25/18
Filed: 1953-04-09
Abstract: 735,596. Lubricating systems. ROLLSROYCE, Ltd. April 9, 1954 [April 9, 1953], No. 9713/53. Class 12 (3). A lubricating system comprises a reservoir which is put under gas pressure to cause the lubricant therein to drive a rotary motor of the volumetric displacement type, the rotation of the motor being controlled by speed-governor means whereby the lubricant is volumetrically metered before delivery to one or more points. As shown, an annular reservoir 10 is formed at the leading edge of an air-intake duct 11 of a gas-turbine engine. The compressor of the engine is connected to supply heated air through a pipeline 12, annular member 13, duct 14, restricted orifice 15 and duct 16 to the interior of the reservoir. The lubricant flows through outlet duct 18, a filter element 21, a rotary motor 23, and pipeline 24 to the bearings of the engine rotor. The speed of rotation of the motor 23 is controlled by a centrifugal speed governor 25 which is driven by the motor and comprises a shaft 27 with a fixed collar 28 and a sliding collar 31 which are connected by leafspring elements 30 supporting weights 29. The weights engage an annular friction pad 32 within a stationary housing 33 whereby the relation of the shaft 27 is maintained as a predetermined speed. Flow of air from the compressor is controlled by means of a restriction 15 and a by-pass passage 35 closed by a valve device 36. The valve is connected to one side of a diaphragm 38 which at the other side is loaded by a spring 37 and is subjected to oil pressure through a passageway 39. If the oil is viscous such oil pressure is low and the valve 36 is opened due to the pressure of air in the duct 14 allowing an increased flow of air to the reservoir by way of the by-pass 35. Instead of the centrifugal governor a clock-type escapement mechanism may be used to control the speed of the motor.
