Title: Compressor for a gas turbine engine
Inventor: ROBINSON NORMAN ROBERT
IPC: F04D29/54
Filed: 1963-04-08
Abstract: 960,812. Axial-flow compressors; jet propulsion plant; compressor blade mounting. ROLLSROYCE Ltd. April 8, 1963, No. 13997/63. Headings F1C, F1J and FIT. A compressor 13, Figs. 1 and 2, for a gas turbine engine comprises a cylindrical outer casing 20 within which is secured an inner casing 21 which has a series of axially consecutive rings 23-30 each provided with at least one stage of stator blades 33, the series of rings comprising a number of axially consecutive unsplit rings 23-26 disposed at the upstream portion of the compressor and at least one ring 27-30 split substantially axially and arranged at the downstream portion of the compressor, the or each split ring 27-30 being provided with support means directly connected to the outer casing 20. The rings 27-30, having strengthening ribs 9, are split along a sinuous line 48, Fig. 3 (not shown), extending substantially axially between the stator blades 33. These rings are supported from the outer casing 20 by flanges 36 having rims 37 located in slots 38. Each flange 36 is provided with a number of slots 40 and holes 41, Fig. 4, to increase its resilience so that the rings 27-30 may conform to the shape of the casing 20 during cold start and hot shutdown conditions. The resilience of each of the adjacent flanges 36a is increased by cut outs (shown in dash lines) which are so arranged that each flange 36a closes the slots 40 of the associated flange 36 and thereby prevents recirculation of air between chambers 22a, 22b, 22c and 22d, which may be vented to the compressor 13 by small holes (not shown) for pressure balancing purposes. Air may be bled from the compressor 13 into a by-pass passage 16 of the engine through openings between the blades of the upstream stator stage of ring 28, the chamber 22b and a control valve 45. The upstream stator stage of ring 28 is made by welding or brazing together adjacent blade platforms. The remainder of the stator stages are formed by welding or brazing substantially elliptical platforms into correspondingly shaped slots in the respective ring 23-30, the radial thicknesses of the ring and platforms being substantially the same.

Title: Improvements in and relating to the treatment of coal tar distillates and to the production of phenols or tar acids of high boiling point
IPC: C10C1/20
Filed: 1940-09-18
Abstract: 545,461. Purifying coal tar distillates. YORKSHIRE TAR DISTILLERS, Ltd., and MILNER, D. W. Sept. 18, 1940. No. 14332. [Class 2 (iii)] Unsaturated olefinic compounds are removed from coal tar distillates by treating the distillates with a phenol at normal or elevated temperature in the presence of catalysts or condensing agents, known for promoting the alkylation of phenols with olefins. As catalysts there may be employed acids such as sulphuric acid, and phosphoric acid, sulphonic acids and particularly phenol sulphonic acids. Metal such as anhydrous aluminium chloride, 'ferric chloride and zinc chloride may also be used. The preferred phenols are monohydric phenols, although polyhydric phenols 'may also be used. The phenol is mixed with from 0.1 per cent. to 10 per cent. by weight of catalyst, and the proportion of phenol is adjusted to correspond with the amount of unsaturated compounds in the coal tar distillate. In examples (1) a mixture of phenol and 95 per cent. sulphuric acid is reacted with naphtha of boiling range 135‹ C.- 155‹ C., and the re-action product fractionated to give a naphtha free from unsaturated compounds and some high boiling tar acids. (2) naphtha is refluxed with ortho-cresol containing phosphoric acid. (3) Benzol front runnings is refluxed with xylenol containing 95 per cent. sulphuric acid. (4) Naphtha is refluxed with meta cresol and 95 per cent. sulphuric acid. Specifications 460,435 and 473,438 are referred to.
Patent GB-560166-A (GB)
Title: Improvements in or relating to the oxidation of unsaturated aldehydes
IPC: C07C51/25
Filed: 1940-09-21
Abstract: Acrylic acid is made by oxidizing acrolein with molecular oxygen in the presence of an acidic compound of vanadium at a temperature not above 45 DEG  C. and, if desired, in the presence of a water-miscible solvent such as acetic acid, acrylic acid, or acetone.  The recovery of the product from the reaction mixture may be effected without polymerization by adding a substance which will decompose the peroxide compounds present such as sulphur dioxide.  The oxidation may be effected under conditions which prevent saponification during the process and recovery stages in which case acrylic anhydride is obtained.  The acrylic acid in the reaction product may be esterified with acetylene or an alcohol, or an alcohol may be added initially so that esterification occurs during the oxidation.  Examples are given. The Provisional Specification includes the oxidation of alpha substituted acrolein such as methylacrolein and chloracrolein, and mentions other catalysts including compounds, preferably acidic compounds, of chromium, tungsten, molybdenum, osmium and uranium and polyacids of such metals such as phosphotungstic and phosphomolybdic acids.

Title: Machine including two coacting cylinders and a device for measuring the pressure setting between the cylinders
IPC: B41F33/02
Filed: 1975-04-10
Abstract: 1494786 Measuring forces photo-electrically ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER A G 10 April 1975 [10 April 1974] 14816/75 Heading G1A [Also in Division B6] The pressure between two cylinders, e.g. in a printing press, is measured by mounting a mirror 6, Fig. 1, on the end of one cylinder and reflecting light to and fro between this mirror and a further mirror 12; as the pressure changes, the cylinder bends and this causes the position of the reflected beam to vary relative to a detector 18. The beam position is measured either by placing the detector so that more or less of its surface is illuminated according to the position, or by using an array of detectors and counting the number illuminated as the beam moves across them, or by using a detector whose sensitivity varies along its length (either intrinsically or due to an associated filter); it is also possible to use one detector to count the number of reflected beam portions which pass over it as the cylinder bends.  The positions of the light source and detector are adjustable by screws 16, 19, while a screw 13 allows the mirror 12 to be placed parallel to, or at a small inclination to, mirror 6. Similarly, screws 7 allow mirror 6 to be pre-set normal to the cylinder axis. The source, detector and mirror 12 are mounted in a housing 10 which can be rotated so that the measurements are carried out in the plane of maximum bending.
