Title: Catalytic oxidation of organic compounds
IPC: B01J8/04
Filed: 1928-11-21
Abstract: 300,968. Selden Co., (Assignees of Jaeger, A. O.). Nov. 21, 1927, [Convention date]. Mineral and tar oils, purifying.- In a process for catalytically oxidizing organic compounds, applicable to the purification of crude light oil fractions by selective oxidation of impurities, the vapours of the organic compounds in admixture with oxidizing gases are passed through heat-exchanging elements at least partly embedded in a catalyst layer, the gas being in indirect heatexchanging relation with the catalyst; the flow is then reversed and the gas passed in direct heat-exchanging relation with the catalyst and with the incoming gas; and finally the gas passes after another reversal of flow through the catalyst layer. In the illustrated modification the gas passes down the tubes 9, up the surrounding tubes 11, and down through the catalyst layer. In other modifications the passages are in the form of concentric annuli instead of separate tubes. One ingredient or a portion of the reaction mixture may be directly admitted to the catalyst space, e.g. by the pipe 14. A part or all of the reaction product may be recirculated through the converter, either with or without previous separation of particular products or correction of its composition; in the illustrated apparatus a portion of reaction product withdrawn at 48 has its composition corrected by admission of gas at 51 and is recirculated to the inlet pipe 5 by the blower 52 in amounts controlled by the thermostat 58. The incoming gas may be preheated, e.g. by heat exchange with the reaction products, or cooled as required, and a cooler may be inserted in the recirculation system. The internal heat-exchange tubes may extend through the whole or only a part of the catalyst layer or may project into the gas space beyond it. Separate uncooled layers of catalyst may be provided subsequent to the main body. Additional means for cooling the catalyst or for equalizing its temperature may be employed; the figure shows heat-equalizing elements 55 embedded in the catalyst and either projecting above it or not. These may be solid rods of conducting material or tubes filled with liquid which may or may not vaporize under the conditions of use. Specification 283,887, [Class 1 (i), Chemical processes &c.] is referred to.

Title: Adsorption separation process
IPC: B01D53/047
Filed: 1963-09-02
Abstract: 1,067,177. Separating gases. UNION CARBIDE CORPORATION. Sept. 2, 1963 [Sept. 4, 1962]. No. 34515/63. Addition to 989,073. Heading B1L. A fluid feed stream is purified by contacting it with one end of an absorbent bed at a first higher pressure, continuing the adsorption process until the impurity adsorption front has reach a predetermined point within the bed, discontinuing the introduction of the feed, removing fluid trapped in voids in the bed and moving the impurity front further forward by concurrently depressurising the bed and then desorbing the absorbent, the absorbent bed comprising activated AL 2 O 3  alone or together with SiO 2  gel, activated C or a zeolitic molecular seive. The process may be used to treat gaseous mixtures containing H 2 , O 2 . N 2 . Ne, Ne, Ar, Kr, NH 3 , H 2 O, CO 2 , CO, SO 2 , H 2 S, CH 4 , C 2 H 8 , C 3 H 8 , C 4 H 10 . C 2 H 4 . C 3 H 6 , C 4 H 8 , C 2 H 2  and higher saturated and unsaturated hydrocarbons. A feed stream at 100‹F and 750 psig passes via line 10 and valve 12 to adsorber A containing first a layer of silica gel and then a layer of zeolitic molecular seive. The partially impurity depleted feed stream is fed via lines 14 and valves 16 and 18 to adsorber D containing a plurality of adsorbents including activated alumina, weak adsorbate impurities being adsorbed in adsorber D until the adsorption front reaches a predetermined point within the adsorber D, but the adsorption front in adsorber A is not stopped at a predetermined point. The product effluent from D passes through lines 20 and 34 via valve 22 a portion being diverted along line 21 to repressurise bed F whilst another portion cools bed C which has previously been heated and desorbed. The warm effluent from C is further warmed at 60 and passed via line 28 to bed B which has previously been used for adsorption, and is thereby desorbed and the desorbate vented through cooler 62. Bed D is depressurised cocurrently with valves 18 and 22 closed and valve 38 open, the void gas being passed to adsorber F. Adsorber E which has just completed a cocurrent depressurisation step, is desorbed by opening valve 42, thus allowing the weak adsorbate constituents to leave through conduit 52. In another embodiment (Figs. 1 and 2, not shown) four adsorbers are used in a continuous process wherein at any time, one bed is being used for adsorption whilst the others undergo the steps of co-current depressurisation, desorption and repressurisation respectively.

Title: Improvements in or relating to machines for conjointly lasting and stitching veldtschoen
IPC: A43D23/00
Filed: 1920-12-07
Abstract: 176,496. Ricks, F., Woodcock, R. B., and British United Shoe Machinery Co., Ltd. Dec. 7, 1920. Boot-sole stitching and lasting machines. -Veldtschoen work. The auxiliary positioning - means or sole - straightening tool described in Specification 20047/14 is driven through mechanism whereby it may be brought into and out of operation during work upon the shoe preferably by means of a lasting gripper control slide described in Specification 22110/13. The arm 5 actuating the auxiliary positioning-means is connected to the upper end of a link 19 pivoted to a cam-lever 21. A strut 23 is pivoted to the link and is supported by a pin 39 on a link 37 actuated by a cam-slot 47 in the slide M. In the position shown the link 19 oscillates about the pin 33 and the rod 5 is not actuated. By lowering the slide M, the rod 37 is lowered removing the support of the pin 39 and a cam-plate 31 is turned so as to force the link 19 to the right and permit the strut 23 to fall behind a stop 43. Thereafter, the strut provides a pivot for the link 19 and the motion of the pin 21 is transmitted by the link to the rod 5 and the auxiliary positioning-means. In the downward movement of the slide M, at the first stage, the lasting gripper is moved forward and given a short range of pulling action, at the next stage, the action of the gripper is unchanged but the auxiliary positioning-means is brought into action and, in the last stage, any movement of the slide increases the action of the gripper correspondingly. The close of the first stage is indicated by the resistance of a spring plunger which then comes into action. The field of oscillation of the auxiliary positioning- means is raised by means of an eccentric pivot connection at the forward end of the rod 5. The pivot may be turned by means of a finger-lever and is held by a spring catch.

Title: Improvements in and relating to methods of casting
IPC: B22C9/04
Filed: 1934-12-03
Abstract: 440,296. Moulding processes. AKERLUND, E. G., 7, Riddaregatan, and ELMQVIST, C., 5, Snickaregatan, both in Stockholm. Dec. 3, 1934, No. 34676. [Class 83 (i)] Patterns.-Metal castings are produced from a pattern by casting an elastic negative from glue material round the pattern, casting wax or other fusible material in the negative to form a hollow positive, casting a refractory core in the positive and a refractory mould about the positive, melting out the positive and replacing it by casting metal. The pattern 10 is first coated with a layer of clay 11 which is then surrounded by plaster of Paris 9 which may be removed in sections. The clay is removed and an elastic material is poured into the space between the pattern 10 and mould 9. The elastic material may comprise a mixture of glue or gelatine, glycerine and alum, in the proportions 93 per cent, 5 per cent, and 2 per cent by weight. The elastic negative is removed, if necessary by slitting, and is treated with alum, formic or tannic acid, &c. to toughen it. The negative is then replaced in the mould 9 and is coated internally with a material having a lower melting point than the negative. Thus wax may be poured into the negative and applied to the walls by rotation. The interior of the wax positive is filled with a fluid investment material 14, which hardens. A suitable material comprises plaster of Paris, pulverized quartz or sand, and aluminium silicate clay. The elastic negative is removed and supports 15 are inserted in the wax which is then encased in similar investment material 16. The entire assemblage is heated to 600‹ C., thus drying the investment and causing the wax to melt and run out through a vent 18. The space previously occupied by the wax is finally filled with molten metal and the investment removed. The supports 15 are pulled out and the surface of the cast is smoothed.

Title: Improvements in sheet registering mechanism
IPC: B41F21/10
Filed: 1946-11-22
Abstract: 628,996. Feeding sheets. HOE & CO., Ltd., R. Nov. 22, 1946, No. 34705. Convention date, Nov. 23, 1945. [Class 100 (i)] A sheet-feeding and registering mechanism for use with rotary printing-machines of the kind described in Specification 626,649, is constructed with a sheet-timing cylinder 11 which registers the sheets before being taken by the grippers 32 of a sheet-taking cylinder 12, the cylinder 11 being a half or other submultiple of the diameter of the cylinder 12 and being driven so as to have the same peripheral speed. The cylinder 11 is fitted with registering stops 38 which are projected through an aperture in the cylinder to engage a sheet forwarded by conveying mechanism similar to that in the prior Specification at a greater speed than the stops 38. The stops 38 are carried by a shaft 81 which is oscillated by a cam 46 engaging a roller 44 on a lever arm 79 pressed towards the cam by a spring- pressed rod 82. The cam 46 is rotated by planetary gears including a fixed sun wheel and the stops 38 are at their maximum amount of projection from the cylinder at about the time at which a sheet is advanced for its front edge to be engaged by grippers 32. The stops 38 move faster than registering stops 19 projecting from a gripper pad 35, and when the sheet is registered against the stops 19 the grippers 32 close on the sheet, and the stops 38 are accelerated and are moved inside the gap in the timing cylinder. At the next rotation of the cylinder 11 no sheet is fed to the stops 38 and they are retained in the gap. The feed chains 17 are fitted with two specially constructed links 101, 108. The link 101 is fitted with a registering stop 106 integral with a depending guide 107, and the link 108 is fitted with a sheet guide 112 which moves out of the path of the sheet as the link 108 moves around its pulley 41. The grippers 32 are pivoted to an outer shaft 22 carried by the cylinder 12 and are operated by rotation of an inner shaft 21 situated by engagement. of a cam roller 37 with a cam. Motion is transmitted from shaft 21 to the grippers 32 by means of a spring-controlled rod 24 fitted with a collar 27 engaging one end of a slot 28 in the shaft 21.

Title: Obtaining error analysis data for a system
IPC: G01R31/00
Filed: 1973-07-20
Abstract: 1399186 Fault detection INTERNATIONAL BUSINESS MACHINES CORP 20 July 1973 [12 Sept 1972] 34791/73 Heading G1U [Also in Divisions G4 and H4] Data relating to errors occuring during operation of a system comprising a number of units is obtained by generating in response to each detected error a number of error points for each unit which probably contributed to the error, the individual numbers being determined in accordance with the type of error, and counting the number of error points generated for each unit in the system. The arrangement is described in connection with intermittent errors occurring in an electronic data processing system although it is stated to be applicable to any data handling system consisting of a number of replaceable units. By analyzing the system involved it is possible to determine for each type of error which may occur a percentage probability for each unit in the system that the corresponding unit was responsible. The probability for each unit is determined in  accordance with the number and type of com-  ponents forming the unit. Each unit in the system has an associated counter which is fed with an appropriate number when an error occurs so that the counters accumulate a count which reflects the operational integrity of the associated unit. The total number of points distributed among the units for a single error may be varied according to the nature of the error, e.g. an error may not be caused by a unit failure, but may be consequent upon an earlier error in which case the total humber of points reflects the probability of the error being due to unit faults. The accumulated counts are used by maintainance staff to determine which units require repair or replacement.
