Filed: 1922-05-02
Abstract: A catalytic material for the partial oxidation of organic compounds consists of boric or phosphoric acid or their salts. The materials are preferably mounted on a carrier; thus, clay, firebrick or magnesia is soaked with boric or phosphoric acid, or silica, kieselguhr, or a metallic oxide, carbonate or nitrate is introduced into molten boric acid.  Mixed catalysts, obtained by adding boric or phosphoric acid to molten metal salts such as nitrates, may be used.ALSO:The partial oxidation of organic compounds is effected by passing the compound in the gaseous or vapour phase, in admixture with an oxygen-containing gas, over boric or phosphoric acid or their salts.  The catalytic materials are preferably mounted on a carrier; thus clay, firebrick or magnesia is soaked with boric or phosphoric acid, or silica, Kieselguhr, a metallic oxide, carbonate or nitrate is introduced into molten boric acid. Mixed catalysts obtained by adding boric or phosphoric acid to molten metal salts such as nitrates, may be used.  According to the examples, (1) formaldehyde is produced by passing ethylene and oxygen over boric or phosphoric acid or their salts mounted on burnt clay or diatomaceous earth; the gases may circulate over the contact mass, the formaldehyde being absorbed in water and further ethylene and oxygen being introduced continuously or at intervals; methane, acetone, ethyl alcohol and cyclohexanone may also be oxidized to formaldehyde in a similar way; (2) anthracene and air passed over the catalytic material yield anthraquinone, benzyl alcohol gives benzaldehyde and ethyl alcohol produces acetaldehyde.

Title: Shift register
IPC: H04L9/34
Filed: 1973-03-15
Abstract: 1356918 Digital transmission; ciphering INTERNATIONAL BUSINESS MACHINES CORP 15 March 1973 [2 June 1972] 12471/73 Heading H4P [Also in Division G4] In an n stage shift register each stage can either have data stored in it or be by-passed. As described when control and address means 12 (Fig. 1) sets all control flip-flops CCF to their "one" state, the apparatus operates as a conventional shift register in which first AND gates A1 are enabled to transfer data stored in each flip-flop FF2 via gates G4 to flip-flop FF1 of the next stage and then AND gates A2 are enabled to transfer the data in flip-flop FF1 via gates G3 to flip-flops FF2. If however the control flip-flop of for example the jth stage is in its "zero" state, gates G2, A1, A2 of the associated stage are inhibited so that data is transferred from the j-1th stage via enabled gate G1 of the jth stage directly to the j+ 1th stage. The shift register may consequently be used for scrambling data by selectively setting the control flip-flop so that for example the first bits of data are entered into the first stages, gates G1 in these stages then being enabled to transfer the succeeding bits of data into the next stages. Data compaction may also be effected by additional gating (not shown) connected to the output terminals of gates G4 so that undesired digits may be eliminated by closing the additional gates of the associated stages.

Title: Improvements in holders for thermionic valves
IPC: H01R33/76
Filed: 1925-05-14
Abstract: 249,357. Braun, L. F. May 14, 1925. Vacuum tubes.-A thermionic valve-holder comprises four arms of conducting material, each carrying at one end a socket for a valve pin and, at the other end, means for attaching it to the panel or other supporting-device in such a manner that the socket is held freely in space. In the construction shown in Fig. 1. the arms are stiff strips 6 of metal and they are attached to the upper surface of a ring 5 of ebonite or other suitable insulating material. Metal sockets 7 for the valve pins are secured to the inner ends of the arms, and terminals 8 are secured to the outer ends. The sockets 7 may be surrounded by sleeves of insulating material, and these sleeves may be suitably coloured for identification purposes. In the construction shown in Fig. 2, the arms are formed in the known manner of springy material, and the sockets 7 have extensions which pass through apertures 11 in a plate 12 formed in one with the outer ring 5. Stops 13 are secured to the lower ends of the sockets, and the plate 12 and a disc 15 of felt or rubber form abutments for the stops 13 to limit the movements of the sockets in both directions. The arms 6 are thus prevented from being bent or broken when a valve is inserted or removed from the holder.

Abstract: 399,588. Turning-gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. May 2, 1932, No. 12553. Convention date, May 2, 1931. Addition to 388,489. [Class 7 (v).] In an electric starter in which the pinion 37 is threaded on a sleeve 16 sliding on splines 13 on the shaft 10 of the starting motor, and axial movement of the sleeve is resisted initially by a weak spring 21 and afterwards by a stronger spring 20, a sufficient axial movement of the pinion relative to the sleeve disengages the threaded connection between them and allows their relative rotation. As shown, the spring 20 bears against a thrust washer 22 and a thimble 26 arranged between the springs limits the compression of the weaker spring 21. At the inner end of the shaft 10, the sleeve 16 abuts against a thimble 29 bearing against a stop collar 32. The threaded sleeve 16 and the bore of the pinion have smooth non-threaded portions 42, 41, so that they are only slightly interengaged in the idle position shown, and are completely disengaged by a predetermined backward movement of the pinion against the pressure of the spring 21, for example on the sudden starting of the engine. A thrust washer 33 and a light spring 34 prevent drift of the pinion into engagement with the engine member 38.

Filed: 1969-03-11
Abstract: 1,204,830. Inert batteries. ESB Inc. 11 March, 1969, No. 12779/69. Heading H1B. Electrolyte entering an inert battery through a filling port in the top is directed through the electrode-separator assembly before reaching the space between the assembly and the container side by a deflector which, with the assembly and the container side, defines a space to accommodate air displaced from between the electrodes. As shown in Fig. 6, conical deflector 32 secured to the wrapping 22 around the assembly of electrodes 10, 15 of an Mg-Agbl/Ag battery ensures that the electrolyte passes through the spiral assembly before entering the peripheral space. With electrolyte passing gap 33 between the deflector 32 and cell top 31 the deflector 33 acts as a Venturi to suck air out of the peripheral space and electrode assembly. In other embodiments (Figs. 4 and 5, not shown) the deflector is fastened also to the top 31 or merely contacts the sidewall 23. In the latter case air is vented from the peripheral space when the pressure rises.

Title: Apparatus and method for fractionating of gaseous mixtures
IPC: C01B33/46
Filed: 1961-04-11
Abstract: 965,566. Separating gaseous mixtures. ESSO RESEARCH & ENGINEERING CO. April 11, 1961 [April 29, 1960], No. 12993/61. Heading B1L. A mixture of gases is separated by passing them under pressure through a bed of adsorbent which preferentially adsorbs at least one component of the mixture, and collecting the product gases remaining, in an accumulator chamber where a predetermined high pressure is built up, and from which the product is taken continuously at a relatively low pressure. The adsorbed components are desorbed by releasing the pressure at the inlet end and preferably also by allowing some product gas to backwash through the bed, and then repeating the cycle. The gas mixture is sucked in through filter 16 into compressor 10 driven by motor 12. It passes through trap 20, valve 24 and into adsorption zone 32 containing an adsorbent 36. Product gas leaves through conduits 50 and 54, through throttle valve 62 and check valve 64 into accumulator chamber 56. From here it is extracted through conduit 66, check valve 68 and throttle valve 70, conduit 72 being a bleed outlet. When a preselected relatively high pressure is reached, pressure sensitive switch 100 opens, cutting off the current supply to solenoids 40 and 86. This causes the position shown in Fig. 2 to be reached, with adsorption vessel 32 open to a region of relatively low pressure, e.g. the atmosphere, by means of conduit 38. This allows desorption to take place. When a preselected pressure difference across relief valve 60 is reached, it opens and allows some product gas in chamber 56 to backwash through the adsorbent. This continues until another preselected smaller pressure difference exists across valve 60, when it closes, and prevents further backwash. All this time, product is being slowly withdrawn through conduit 66. When a preselected low pressure exists in chamber 56, pressure sensitive switch 100 closes and allows the current to flow again, and the position reverts from that in Fig. 2 back to Fig. 1 for another adsorption cycle. The product gas can be arranged to contain any amount of the component adsorbed below its original content down to essentially zero content. For complete removal, the essential condition is F R #F T (P D /P A ) and for controlled removal F T (P D /P A )>F R >O where F T  is the total volumetric flow of feedstream, F R  is the total volumetric flow of backwash product gas adjusted to the same temperature and pressure as F T , P A  is the absolute pressure of the feed stream, P D  is the absolute pressure of the backwash stream entering the body of adsorbent averaged throughout the body. In an alternative arrangement, some or all of the other apparatus may be contained inside the accumulator chamber. Separations possible include the drying of air, using e.g. silica gel, removal of hydrocarbons from air, using e.g. activated carbon, removal of oxygen from air using e.g. molecular sieve 4Š, removal of nitrogen from air, using e.g. molecular sieve 5Š or 13Š. Specifications 850,443 and 965,565 are referred to.
