Title: Method and apparatus for Measuring Gas Pressure
Inventor: BLAKELY ROGER WOLCOTT JR
IPC: G01L13/02
Filed: 1968-01-19
Abstract: 1,160,054. Acoustic measurement of gas pressure. LITTON INDUSTRIES Inc. 19 Jan., 1968 [13 Feb., 1967], No. 3113/68. Heading H4D. Gas pressure is determined from the attenuation of acoustic waves transmitted through the gas, provision being made for dissipating that heat energy of the gas which results from conversion of acoustic wave energy. In the Fig. 2 embodiment the pressure measuring instrument comprises diaphragms 14, 16 with attached coils 26, 28 moving in the magnetic fields of structures 18, 30, 34 and 20, 32, 36. Coil 26 is energized by sine-wave source 60 so that diaphragm 14 acts as acoustic-wave transmitter: diaphragm 16 and coil 28 act as receiver. A porous mass 46 of sintered stainless steel particles constitutes a heat sink to absorb conversion heat which would otherwise affect the measurement accuracy. A housing 10 for the instrument communicates with the gas and defines a volume 11 which contains a substantially constant mass of the gas. A closed loop servo system 65 balances the output signal of coil 28 against a fraction of the source 60 signal tapped off by potentiometer 70, and motor 69 adjusts this fraction until the two signals are equal, whereby the motor shaft position provides an indication of the attenuation. It is shown mathematically that if the diaphragm 14 vibrations expand and contract the gas under isothermal conditions, and if the source 60 frequency is in a given relationship with the effective masses of the diaphragms and their spring constants, then the receiver output is proportional to the absolute gas pressure. The instrument may be used as an altimeter. In a second embodiment (Fig. 4) two identical instruments are provided in a common housing (100), the mechanical vibrations of the two transmitters are in anti-phase, and the outputs of the two receivers are added whereby output components due to extraneous external vibrations are cancelled. Instead of moving coil systems the transmitter and receiver may employ low mass capacitive transducers so that the sensitivity of the instrument to external vibrations is reduced.

Knitted-fabric sewing-machines-A machine for sewing together the two halves of a knitted web, as in closing the toe portion of a " seamless " stocking, comprises a ring 3, Fig. 2, having two semicircular rows of points 4, 4a, one preferably higher than the other as shown, to which the stitches m, m<1> are transferred from the knitting-machine. The ring is mounted on a rotatable cylinder 2. Supported on the base 1 is a semicircular member 5 fixed thereto and a semicircular member 5a hinged to the member 5 at 7. The member 5<a> carries two semicircular sliding members 9, 13<a> provided with transfer points 10 and strippers 14a respectively. In operation, the member 9 is pushed upwards by a rod 11 and the points 10 take the stitches m<1> from the points 4<a>. The member 5a is then swung about the hinge 7 to bring the points 10 above the points 4 and the strippers 14a are actuated to strip the stitches m<1> on to the points 4 along with the stitches m. The parts are then restored to their normal positions and the stitches m, m' are united by sewing-needles x, x<1> the feed being obtained by giving the cylinder a step-by-step rotation. In another construction, the ring 3 may be hinged and the points 4 caused to register with the transfer points 10, as shown in Fig. 5. The strippers are carried by the member 5a and the transfer points by the member 5. To hold up the points 10 during stitching, pivoted catches 21 are carried by an angled member 20 and caused to project under the member 9 by partial rotation of the member 20, In a further modification, Fig. 10, the transfer points are dispensed with, and the point ring, supporting cylinder, and the ring 5 are each made in halves 3, 3<a>, 2, 2<a>, 5, 5<a> respectively and the entire structure composed of the corresponding halves is swung on its pivot 7 over the other part. Fig. 12 shows another arrangement in which the point ring 3 is carried by a ring support 2<b> which is completely inverted to carry the points 4 over the points 10. The stripper 14<a> is mounted on the ring 3 as shown, and the transfer point carrier 9 is slidably mounted on a semicylindrical support 2<a>. When the point carrier is in halves, they may be arranged so as to place the double stitches alternately on either half so that a chain of sewing stitches can be made on each side of the join. The stitch-engaging members may be disposed in straight lines for doubling and uniting the stitches of flat webs.

Title: Process for the manufacture of water soluble products from lignite and similar fossil materials
IPC: C07C51/29
Filed: 1928-02-02
Abstract: 284,670. I. G. Farbenindustrie Akt.- Ges. Feb. 3, 1927, [Convention date]. Chlorine derivatives of lignite, and the Lilce.- Lignite and similar fossil materials, degraded by means of sulphite or by any other means are subjected to the action of chlorine in the presence of alkali, cape being taken to maintain a neutral or weakly alkaline reaction till towards the end of the process. Light coloured, water soluble products containing chlorine are obtained. The expression " degraded lignite or the like " means a lignite or similar fossil material which has been rendered soluble in water and dilute acetic acid and which cannot be re-precipitated from its aqueous solution. Such a product may be obtained bv heating lignite with an aqueous solution of sodium sulphite for 10 hours under a reflux condenser, the liquor being then diluted and a small quantity of caustic soda added, after which the sediment is removed. The clear solution of the degradation product is used as the initial material for the process of the invention. In an example lignite, degraded by means of sulphite, is dissolved in water and chlorinated in a closed vessel, caustic soda being added gradually at the same time. The reaction product is precipitated in a finely divided stabs due to increasing salt content, and on pressing and drying the free acids are obtained as a yellow powder which precipitates gelatine. From the filtrate a product can be isolated by extraction - which also precipitates gelatine but differs from the first product in that it is not precipitated from concentrated aqueous solution by strong .acids.

Title: Production of high quality lubricating oils
IPC: C10G21/02
Filed: 1940-02-24
Abstract: 539,191. Lubricants. OCON, E. A. Feb. 24, 1940, No. 3488. [Class 91] A lubricating oil stock which has been deasphaltized and de-waxed is extracted with a solvent, which removes the cyclic and unsaturated constituents, namely liquid sulphur dioxide, aniline, nitrobenzene, halogen hydrocarbons or phenol, leaving a more viscous paraffinic raffinate and the extract, after removal of the solvent, is treated with a second solvent: namely an organic liquid boiling below 400‹F, such as carbon tetrachloride, an alcohol having from four to eight carbon atoms or an ester thereof together with an auxiliary solvent comprising an aliphatic hydrocarbon fraction boiling between 400 and 650‹C. Anthracene, benzene, turpentine and acetone may also be present in the solvent used to extract the cyclic and unsaturated constituents in the first extraction process. A product suitable for use as an auxiliary solvent in the second extraction process may be obtained from the wax obtained in the dewaxing step by subjecting it to a slow heat treatment at 800-900‹F. at pressures of 5-20 atmospheres pressure. The cracking process may be effected in the presence of a de-hydrating catalyst and hydrogen. The lubricants obtained in the second extraction process may be added to the raffinate of the first extraction, or may first be subjected to a condensation process of the Friedel-Craft type. Naphthene base oils, asphalt base oils, paraffin base oils, especially fractions boiling above 700‹F., are suitable for treatment, and for the removal of asphaltic and resinous material from crude oils, hydrogenation, filtration through clay, asphalt precipitation and treatment with an asphalt absorbent solvent may be used. For solvent extraction of asphalt, liquid sulphur dioxide, aluminium chloride and aniline saturated with water are mentioned. A butane-propane fraction or ethylenedichloride is used as de-waxing agent. In the production of an auxiliary solvent from the wax, the latter is passed with steam and oxygen over pumice impregnated with phosphoric acid. A halogenating -de-halogenating process may also be used or chlorine may be passed into the wax during the cracking process and the resulting vapour passed over aluminium or zinc.
