Abstract: 1,234,183. Electron beam focusing apparatus. MINISTER OF TECHNOLOGY 13 Aug., 1968 [18 Aug., 1967], No. 38250/67. Heading HiD. A focusing lens for an electron probe microanalysis apparatus or the like comprises a coil 20 of frusto-conical shape, thereby increasing the angle # 2  within which may be placed a detector D for measuring X-rays emitted by the specimen 19. The coil may comprise a plurality (e.g. six) of separate concurrently laid lengths of conducting wire extending between conductive segments provided at each end of the cone (Fig. 1, not shown). A cooling block may be arranged within the coil (Fig. 4, not shown), and the coil may be surrounded by a sheath of material of high magnetic permeability (Fig. 5, not shown). The distance between points on the axis where the field of the coil is half the maximum field should be not less than twice the distance d, and the slant height of the coil should be at least five times its radial depth. The half-angle of the cone is preferably 45 degrees and should be between 20 and 85 degrees.

Abstract: 1,234,264. Valves. S. FUJIKI. 21 Oct., 1968 [19 Oct., 1967], No. 49938/68. Heading F2V. A valve comprises a closure member 24 slidable on a rod 7 and biased by a spring 23 towards a seat 15 between an inlet 2 and an outlet 17. A spring 27 biases the rod 7 away from the seat and is overcome by an actuating force on rod 3 in order to seat the closure member. When the closure member is seated a rise in pressure in outlet 17 can unseat the closure member when it is sufficient to overcome the bias of spring 23. The spring 27 bears against a piston 20 mounted on a tapered portion of rod 3 and provided with through passages 29. The rod 3 may be contacted by a member on a crane jib or a lifeboatraising davit to cut off supply of fluid to the operating motor.

Abstract: 1,252,355. Feeding sheets. INTERNATIONAL STANDARD ELECTRIC CORP. 30 Oct., 1969 [2 Nov., 1968], No. 53196/69. Heading B8R. [Also in Division G4] A punched card reader comprises a cassette 3, having a plurality of sections B, C, D, E, each of which can accommodate a stack of punched cards 5, and a slider 2 mounted for movement within a housing 1 upon which the cassette 3 is movably supported, the slider 2 being formed with a shallow recess 2a having a depth such as to receive a single card and being associated with sensing contacts 4a and an electromagnet 7. In operation with the cassette positioned as shown, the lowermost card 5a in section D is received by the recess in slider 2a which is then moved in the direction of arrow A so that the card passes the contacts 4a which sense the punched holes; with further movement, the sensed card 5a is placed below the stack of cards in section C when, upon receipt of a signal from an evaluating unit the electromagnet 7 is energized so that its armature 7a moves upwards through an aperture in the surface of the slider 2 (Fig. 2, not shown) to push the card 5a into the section C, whereupon the slider returns to its initial position to receive another card from section D. Each stack of cards is loaded with a weight 6 having a punched hole code in its bottom surface. Thus after the last card in section D has been properly transferred to the stack in section C the weight 6 drops into the recess 2a (Fig. 3, not shown) but a major portion remains within its section so that when the next feed movement of slider 2 commences the cassette itself is stepped on by one section division. At the same time the hole code of the weight 6 is sensed by the contacts 4a, thus informing the evaluating unit that the stack of cards in section D has been exhausted.

Abstract: 1301835 Stamping BRITISH ROPES Ltd 21 Jan 1970 [27 Jan 1969] 4486/69 Heading B3Q [Also in Division F2] A deformable tubular member (e.g. 1, Fig. 2) is placed over a rigid member 2 so as to overlay a peripheral groove 9 on the rigid member, the side walls of the groove 9 being perpendicular to the surface of the rigid member. An elastomeric ring 8 surrounding the tubular member 1 is then compressed axially by screwing up housing 4, 4a so as to cause it to expand radially inwardly to force part of the tubular member 1 into the groove 9. In the embodiment of Fig. 3 (not shown), the tubular member 1 bridges two pipe ends, each pipe end being provided with a groove 9. Two elastomeric rings are used (one for each groove 9) and the housing for compressing the rings comprises a centrally apertured radial web having a cylindrical extension 5 on either side. The rings are pressed against the central web by screw-on rings 4a as shown in Fig. 2. A permanently deformable sleeve 11 (e.g. of copper) may be interposed between the elastomeric ring and the tubular member 1 so that the elastomeric ring and the housing 4, 4a may be subsequently removed (Fig. 4), the washers 7 in this case being semicircular to allow removal.

The resulting hot, uncooled effluent from the hydrocracking zone is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a vapor stream containing hydrogen, hydrocarbonaceous compounds boiling at a temperature below the boiling range of the fresh feedstock, hydrogen sulfide and ammonia, and a liquid hydrocarbonaceous stream wherein at least a portion of this liquid stream is then passed to the denitrification and desulfurization reaction zone. At least another portion of the liquid stream is admixed with the subsequently cooled vapor stream to produce a hydrogen-rich recycle gas stream and a liquid hydrocarbonaceous stream containing hydrocarbonaceous compounds boiling at a temperature below the boiling range of the fresh feedstock.
