Title: Dehydrogenation catalysts of improved activity
IPC: C07C5/333
Filed: 1966-07-14
Abstract: An hydrocarbon feed comprising at least one hydrocarbon selected from aliphatic monoolefins having at least 4 C, alkylated aromatic hydrocarbons having an at least 2 C alkyl group, cycloaliphatic olefins having 5-8 C and cycloalkanes having 5-7 C is dehydrogenated in the presence of a catalyst comprising at least one Fe compound and a support of which at least 60% of the total pore volume is contributed by power having diameters in the range from 1000-8000 <\>rA.  Examples of dehydrogenations which may thus be effected are butenes 1 or 2 to butadiene, isoamylene to isoprene and ethylbenzene to styrene. Comparative examples describe the dehydrogenation of butene 1 and chromatographic data on the products.  The dehydrogenation of alkanes, e.g. butane to butenes and butadiene, in the presence of molecular oxygen may also be carried out in the presence of the above-mentioned catalyst.ALSO:A dehydrogenation catalyst contains at least one iron compound and a support, of which at least 60% of the total pore volume is contributed by pores having diameters in the range 1000 to 8000  .  Additionally the catalyst may contain Cr2O3.  The supports may be calcium phosphate, calcium nickel phosphate and magnesium phosphate.  The catalyst may be regenerated by passing a mixture of steam and air over the deactivated mass.  In examples the catalysts are used as 3/16 \yF x 3/16 \yF pellets.

Title: Apparatus for the removal of sludge from settling tanks
Inventor: RANDALL WILLIAM
IPC: B01D21/06
Filed: 1952-12-19
Abstract: 742,315. One-way brakes. NORTH THAMES GAS BOARD. Dec. 21, 1953 [Dec. 19, 1952], No. 32329/52. Addition to 707,410. Class 103 (1). [Also in Groups I and XXIX] In apparatus for the removal of sludge from a settling tank comprising a run-off pipe 1 moved intermittently around the tank by the alternate expansion and contraction of a bellows 3 (see Group I or Group XXIX) an anchor device 11 and spragging-mechanism 16 different from those disclosed in the parent Specification are provided. On contraction of the bellows its end-plate 6 moves to the left, whereupon nuts 8, 9 on a rod 7 attached to the plate move a strip 13 (supported at its inner end on the pipe 1) to the left, this in turn moving to the left a carriage 11 by contact with an anchor arm 10A on the carriage having one end close to the rail 12. Movement ceases when the arm 10A again comes into contact with a boss 15. Movement of the pipe 1 to the right during the bellows contraction is prevented by an arm 19 which through a bolt 19A having loose connection with an anchor arm 17A on a carriage 16 pulls the anchor arm to the right, thus jamming its inner end, and that of a similar lug 17B, against the rail 12. When the bellows expands, movement of the plate 6 to the right is prevented by engagement of the boss 15 with the anchor arm 10A which in co-operation with a lug 10B thereupon locks the carriage 11 against the rail 12. Accordingly, the end of the pipe 1 moves to the left, the arm 19 sliding the carriage 16 along by engagement of a rubber spring 20A upon it with the anchor arm 17A.

Title: Apparatus and method for analysing the dynamic deflection of tires
IPC: G01H3/00
Filed: 1954-11-09
Abstract: 760,458. Electric measuring systems. GOODYEAR TIRE & RUBBER CO. Nov. 9,1954 [June 10, 1954], No. 32365/54. Class 40 (1). An apparatus for locating and measuring the local changes in deflection characteristics of the side walls of tyres which cause tyre thump comprises means for rotatably supporting the tyre under load, means for rotating the tyre, means for rotating a support bearing deflectionresponsive electromechanical transducer means adjacent the sidewall at an angular speed close but not equal to the tyre speed and means for recording the transducer output. The tyre 1 is loaded and rotated about fixed axle 5 by pressing it against a rotating roller 65 (Fig. 5). The transducer, e.g. a Rochelle salt crystal 55, with a feeler 56 is mounted via conductive arms 54 on an extensible arm 47 biased towards the sidewall by spring 50. The arm is mounted on member 20 (Fig. 2), driven at a speed slightly above that of the wheel through step-up gearing generally designated as 12. The transducer output is fed through brush 58 and sliprings 59 to an amplifier 61 and a filter 62 passing primarily frequencies around the rotation frequency, the filter output being amplified at 63 and recorded by direct writing recorder 64. The record consists of pulses corresponding to successive passages of the pick-up past the tyre contact area. Since at succeeding passages different parts of the sidewall are adjacent the pick-up an analysis of a record corresponding to a complete rotation of the pick-up reveals increases in deflection characterizing any weak. nesses which caused tyre thump, the faults being distinguishable from those due to other irregularities by the relatively sharp increase in deflection. If the tyre was marked with the initial position of the pick-up the position of the fault is immediately obtained from the record; alternatively the test is repeated and the rotation stopped when the characteristic part of the record recurs. The step-up gearing comprises ring gears 37, 45 mounted on axle 5 and an extension 19 of member 20 respectively and a casing 28 driven by the wheel and in which are housed a pair 33, 34 of axial pinions and 38, 39 of the transverse pinions each pinion carrying a spur gear and worm. The spur gears on the axial pinions run round ring gear 37 and drive through their worms the spur gears on the transverse pinions. The ring gear 45 is driven off the worms carried by these latter pinions.

Abstract: 498,263. Photo-mechanical printiiigsurfaces. JACKSON, L. MELLERSH-. (Photo-Cylinder Corporation) Nov. 25, 1937, No. 32550. [Class 98 (ii)] Originals for producing etched intaglio printing-formes are produced by exposing a sensitive layer to the original using a halftone screen in conjunction with a stop in the shape of a regular figure, e.g. round or square and then exposing it to a uniformly lighted surface through a half-tone screen using a slotted diaphragm which produces a series! of lines in the parts of the negative correspondling to the darkest tones. The exposures may be made in reverse order. A positive is made from the resulting negative and is used to prepare the printing forme in known manner. The effect of the exposure with the round stop is to produce large overlapping dots a, Fig. 2, in the high lights, disconnected dots b in the intermediate tones, and very small widely spaced dots c in the dark tones. The second exposure produces lines which do not show in the high lights, connect the dots in the intermediate tones, and obliterate those in the dark tones as shown in Fig. 3. The resulting negative is printed by contact to form a positive which is again printed by contact on to a metal plate coated with sensitized asphaltum. The plate is afterwards etched giving recesses of uniform depth varying in size and separated by ribs which serve to support the doctor blade.
