Title: Improvements in or relating to plants for storing and delivering inflammable liquids
IPC: B67D7/32
Filed: 1922-06-19
Abstract: 181,743. MauclÞre, P. A. P. V. June 20, 1921, [Convention date]. Addition to 166,551. Direct air-pressure apparatus, automatic; aircompressing devices, application of; raising by stages; measuring-devices, applications of; utilizing air repeatedly.-In plants in which an inert gas contained in a storage cylinder is used in a closed piping circuit and is successively admitted into and expelled from two auxiliary vessels in order to force liquid from one to the other a compressor is alternately in communication through a fourways tap with the first auxiliary vessel in connection with the main tank and with the second or measuring vessel and the supply pipe, which is on the piping providing for the passage of liquid between the two vessels. By putting pipes 12<a> and 14 and 12 and 14<a> respectively into communication, gas is withdrawn from the vessel 2<1> by the compressor 4, and compressed into the vessel 2<2> causing liquid to be drawn up from the tank 1 into the vessel 2<1>. Pipes 14 and 14<a> and 12 and 12<a> are then put into communication and gas is then drawn from vessel 2<2> into the vessel 2<1>, causing liquid to rise from the vessel 2' through the pipe 13 into the vessel 2<2>. The inter-connected taps 53, 54 are then turned to cause the pipes 12<a>, 14 and 14<a> to communicate and short-circuit the compressor. The liquid is drawn off from the vessel 2<2> by tap 37 with the compressor working whereby the vessel 2' is simultaneously filled from the tank 1. The vessel 2<2> when empty is again filled from the vessel 2<1> as above. Valve 59 allows automatic adjustment of the pressure on each side of the compressor. To put the apparatus in the non-operative position, pipes 14 and 14a and 12 are put into communication as shown in Fig. 5 and valve 51 opened and all liquid flows by gravity into the tank 1 when the pressure should become atmospheric. The apparatus is filled with inert gas before working, from cylinder 28, by special manipulation of the apparatus. Tap 58 is provided to adjust the pressure. The vessel 2<2> has a liquid level gauge 52.

Title: Processes for the preparation of aluminate of lime for the manufacture of pure alumina
IPC: C01F7/164
Filed: 1920-06-23
Abstract: Calcium aluminate is produced by heating coarsely crushed bauxite and limestone at a temperature such as not to cause fritting, for instance in a rotary furnace, and then fusing the mixture in a second furnace.  The fused product may be granulated in water.  The first heating may be effected by gases from the second furnace.  The Specification as open to inspection under Sect. 91 (3) (a) states that alternatively a blast furnace may be employed, the p  charge consisting of alternate layers of red bauxite (which may contain 32-35 per cent of ferric oxide) mixed with limestone and of coke. The aluminate is recovered as a liquid slag and the iron as pig iron. In another modification, a converter is employed. It is charged with pellets of a mixture of bauxite, limestone, and coke dust upon a bed of kindled coke.  An agglomerated mass of crude aluminate is obtained, which is discharged by tilting the converter.  This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for counting or examining optical interference rings or lines
IPC: G01B9/02
Filed: 1945-07-10
Abstract: 595,940. Interferometers utilising light sensitive cells. STULAND, T. July 10, 1945, No. 17580. [Class 40 (iii)] [Also in Group XX] Interference patterns are imaged on a mask constituted by an image (e.g. a photographic negative) of the pattern, so that any disturbance results in light passing through the mask to a photo-electric cell. In Fig. 1, the interference pattern is produced by light from a source S, reflected from fixed and movable reflectors M2, M3, and the cell PE actuates a counter C to count the production of bands as M3 is moved and thus indicating the extent of movement. To determine an unknown wavelength in terms of the light from S, a similar system is added using the other side of M3 as a reflector, so that a comparison of the two counters enables the wavelength to be compared, Fig. 3, not shown. By using equipment developing Newton rings, vibration can be detected, Fig. 3, not shown. The invention may also be applied to measure changes in refractive index.

Abstract: 402,502. Revolving cylinder pumps. THOMA, H., 9, Bachstrasse, Karlsruhe, Germany. June 22, 1932, No. 17654. [Class 102 (i).] In hydraulic motor and pump valve mechanism a ported cylinder block is arranged to rotate upon a ported distributer valve face, the contact faces being dished, stepped, or plane, and being provided with oil grooves to which oil can flow through throttling ducts from the main ports whereby a supply of oil is maintained between the surfaces which maintains the same in stable equilibrium with a small clearance between them so that the pressure between the rubbing surfaces of the valve face and cylinder block is balanced or relieved. In the distributer valve face shown in Fig. 1, the grooves 41 for containing oil are fed from the supply port 40 by means of small ducts 42. Where the contact surfaces are small the grooves 41 may be formed in extension surfaces which may be stepped, and where a soft alloy is used the ducts 42 may be formed in hard metal (bronze) bars let into the surface. Fig. 4 shows an arrangement in which oil laaks from the port 40 past raised annular faces 72, 73 which face packings 50, or both faces have the packings. Contact surfaces 76 inside and outside the packings, closed at the periphery by an annular rim 79, are formed with surfaces which are bevelled on the approach side to give a viscosity pump effect for developing lifting pressure when the surfaces come close together. Specification 12574/09, [Class 102 (i), Pumps &c.], is referred to.
