Title: Refining of hydrocarbon oils
Inventor: SCHUMAN SEYMOUR CYRUS
IPC: B01J8/22
Filed: 1961-08-10
Abstract: A sulphur-containing heavy oil containing at least 10 vol percent of hydrocarbons boiling above 900 DEG  F. is refined by subjecting the oil whilst substantially in the liquid phase, and in the presence of hydrogen, to cracking to convert at least 25 vol. per cent of the hydrocarbons boiling above 900 DEG  F. to those boiling below 900 DEG F., separating the residual high boiling hydrocarbons, and reacting the remainder of the cracked oil, whilst substantially in the liquid phase, with hydrogen, in the presence of a particulate sulphur-resistant hydrogenation catalyst, to effect desulphurization. The process is preferably carried out at at least 800 p.s.i.g., especially 800-3000 p.s.i.g.  The cracking is preferably effected below 1000 DEG  F., and the desulphurization at 750-830 DEG  F.  The cracking is preferably effected by passing the oil upwardly through a mass of substantially non-catalytic particles, for example sand, alumina, clay, or bauxite, such that an ebullated bed is formed.  The desulphurization may also be effected in an ebullated bed.  The separation of the hydrocarbons boiling above 900 DEG  F. may be effected by separating the cracked effluent into gaseous and liquid phases, without substantial decrease of temperature and pressure, cooling the gaseous phase, for example by indirect heat exchange with the feed entering the cracking zone, to partially condense the cracked hydrocarbons, and passing the so-cooled phase to the desulphurization stage.  The liquid phase may be fractionated and material boiling below 900 DEG  F. passed to the desulphurization stage.  Residual material may be recycled to the cracking stage. Suitable desulphurization catalysts include cobalt molybdate deposited on alumina, tungsten sulphide, and the mixed oxides of iron and chromium. Specification 884,752 and U.S.A. Specification 2,910,433 are referred to.

Title: Improvements in or relating to directional aerial systems
Inventor: MORAN MICHAEL JAMES
IPC: H01Q13/02
Filed: 1959-08-25
Abstract: 894,342. Aerials. DECCA RECORD CO. Ltd. Nov. 23, 1960 [Aug. 25, 1959], No. 29122/59. Class 40(7). A directional aerial system comprises a length of rectangular waveguide containing a series of slots in each of two opposite faces and means for guiding the radiation from each series of slots into a radiating aperture extending along the waveguide in a plane perpendicular to said faces so that the components of radiation polarized parallel to the longitudinal axis of the waveguide are combined additively whilst those polarized transversely are combined subtractively. A rectangular waveguide 10 in which energy is propagated in the H 01  mode contains slots 11, Fig. 1, in its narrow faces inclined to planes perpendicular to the longitudinal axis of the waveguide which radiate components 12 parallel to the axis and transverse components 13. If the slots radiate in anti-phase (i.e. adjacent slots radiate in anti-phase relative to each other if fed in phase) as do those illustrated, the components 12 result in directional beams in a plane parallel to the broad face of the waveguide with side-lobes produced by the components 13. A beam highly directional in a horizontal plane without sidelobes due to this cause is stated to arise from the mounting of such a slotted waveguide with its longitudinal axis horizontal and its narrow faces 21, Fig. 3, at the top and bottom of the waveguide, with reflecting plates 23 and 24 to guide the radiation around curved paths to the throat 25 of a horn with radiating aperture 27. The longitudinal polarized components of radiation (corresponding to 12, Fig. 1) have their E vectors normal to the paper and combine additively at the throat whilst the transversely polarized components from corresponding slots in the opposite faces 21 have their E vectors in the direction shown by the arrows 22 and are in opposition at the throat. The slots may radiate in-phase, may be spaced in any desired manner, and the aerial may comprise two apertures (one for each series of slots) or may act as a feeder for a reflector.

Title: Improvements in article dispensing apparatus
IPC: G07F11/06
Filed: 1968-06-20
Abstract: 1,202,815. Dispensing articles. U.M.C. INDUSTRIES Inc. 20 June, 1968, No. 29407/68. Heading A4T. Each column of an article dispensing apparatus has shelves 11 pivoted on a support 5 about horizontal arms from a latched horizontal article-supporting position, with successive release of shelves from the bottom up. Each shelf has a latch 25 and a trip 27 mounted on a pivot pin 49, a torsion spring (65, Fig.3) biasing latch 25 clockwise, Fig. 9, so that a latch hook 55 can engage a wire element 43b on the shelf to maintain the latter latched. Ends 45 of the wire element provide pivots for the shelf. A part (65a, Fig. 3) of the spring biases trip 27 anticlockwise so that a trip finger 71 is biased towards a latch hook 61, but for each shelf, except the lowermost, the trip finger 71 is held spaced from latch hook 61, by a lug 31l on the shelf below engaging a trip arm 69. This holds the trips in retractive positions in which cam followers 77 on arms 69 are out of the path of movement of tripoperating fingers (79, Fig. 3) of a vertically reciprocable release bar (81). The lowermost trip is in an operative position in which its follower 77 is in line with the lower most finger of the bar. To release the lowermost shelf, a rod (93, Fig. 1) is pulled against a spring and released to raise and lower bar (81) through a linkage comprising a pivoted lever (89) carrying a roller (99, Fig. 2) lying between flanges (101, 103, Fig. 14) on a pivoted crank arm (105), and a link (111, Fig. 13). As bar (81) is raised, the lowermost finger (79) engages the lowermost follower 77 causing trip arm 69 and latch hook 55 to swing upwards so that the latter disengages from element 43b. The lowermost shelf swings down to an inclined position (Fig.11) in which element 43b is caught by latch hook 61. As bar (81) is lowered, spring (65) biases the latch and trip to swing down and hook 61 clears element 43b so that the shelf swings down to the depending dispensing position (Fig. 12). As this occurs, the lug 311 on this shelf moves out of engagement with trip arm 69 of the second shelf, and the spring part (65a) of the second shelf moves the trip from the retractive into the operative position. When the top shelf has been released, it allows a lever (123, Fig. 1) to pivot, thus allowing through a wire (133) a latch (115, Fig. 1) to slide down into blocking engagement with lever (89). The lowermost shelf is raised for reloading by pivoting a lever (139, Fig.1) down, lever (139) being connected by a wire (143, Fig.14) to a fixed lever (135) having a roller (145) engaging underneath the bottom shelf. The remaining shelves are raised manually.

Title: Clutch and brake assembly
IPC: F16D13/02
Filed: 1973-06-21
Abstract: 1384497 Friction clutches; clutch/brake combinations; band brakes; one-way brakes CARL G PETERSON CO 21 June 1973 [25 Aug 1972] 29425/73 Headings F2C F2L and F2E A helical spring clutch and brake combination comprises a driving pulley 38, a driven collar 32 fixed to a driven shaft 20 and a fixed hub 48 between which a portion 46 of the pulley 38 is an annular gap, a continuation of an annular groove 34 of the driven collar 32, through which groove and gap extends a helical spring 60 connected at one end to the collar 32 and at the other to a control cam 66. The control cam 66 has a plurality of magnets 76 mounted in it and  is held against rotation in the clutch-disengaged, brake-engaged, condition by a solenoid 82 controlled latch 78 which abuts a shoulder 72 of cam 66 under the bias of a spring 90. The spring 60 is here wound around fixed hub 48 to hold collar 32 and shaft 20 stationary. On release of latch 78 by actuation of solenoid 82 the cam 66 starts to rotate with the closely adjacent pulley 38, 78 through the effect of magnets 76 and this unwinds the spring 60 to cause it to engage the outer part of gap 34 and so engage the clutch. The de-energization of solenoid 82 allows the latch 78 to halt the cam 66 and reverse this action. The shock of the sudden engagement of the brake is absorbed by a spring 58 which allows movement of an arm 50 holding the hub 48 stationary. A one-way bearing 30 which mounts the shaft 20 and a drag brake 104, 108 acting on this shaft help to prevent any reverse rotation of this shaft. The clutch-brake combination may be used in presses.

Abstract: 785,291. Making plaster &c. moulds. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Jan. 27, 1955 [Oct. 27, 1953], No. 29652/53. Class 87(2). [Also in Group XXII] A method of moulding or casting a body having a curved or twisted surface includes setting up in spaced relationship two or more correctly profiled templates and stretching a sheet of pliable material in contact with the profiled edges of the templates and casting material against the sheet to form the body. The sheet may then be removed and the curved or twisted surface of the body used as a mould by casting an article, e.g. a model for a copying machine against said surface. In one embodiment, Figs. 1-3, templates, 3 having convex knife edges complementary to the profile of the concave surface of the blade which is to be copied from the cast model are adjustably mounted on a baseplate 1, and a rubber or neoprene sheet 7 is tensioned across the templates and held by clamps 8, 14. Plaster is then poured between the templates and into contact with the sheet 7 through holes 16 in the baseplate. The plaster cast, with inset templates on baseplate 1, is then mounted between side and end walls 17, 18 and the metal model cast in the mould thus formed. The model is preferably cast oversize to allow cleaning up, and the plaster is therefore scraped away to leave the templates a few thousandths of an inch proud of the plaster surface, thus producing reference lines 19 on the cast model. For models having a convex surface, the templates then having concave profiles, the sheet may be integral with, or constrained against the templates by, an inflatable cushion. In a modification, Fig. 4, a length 27, or overlapping strips, of pliable material such as linen backed tape is tensioned across the concave knife edges of the templates 3 and secured by adhesive to the end templates. Plaster is then introduced between the templates and above and in contact with the tape, the tape is removed and the metal poured into the tunnel formation of plaster and templates through a runner 30.
