Title: A process for lowering the olefin content of olefin-containing hydrocarbon fractions
IPC: C10G50/00
Filed: 1943-09-09
Abstract: Olefin-containing hydrocarbon fractions boiling substantially within the motor fuel range are treated to reduce their olefin content by contacting a stream thereof with a solid catalyst consisting of an acid-acting oxygen compound of phosphorus and a siliceous or aluminiferous carrier at about 125 DEG , preferably 175 DEG  to 325 DEG  C. and sufficient pressure to retain at least a substantial part of the fraction in the liquid phase, and at such a rate of flow within the range of about 0.5-10 : 1 by weight of hydrocarbons to catalyst per hour that the liquid product boiling below the end point of the initial fraction has a bromine number less than half that of said initial fraction.  Oxygen acids of phosphorus, particularly phosphoric acids of higher water content than the meta, such as the ortho and pyro acids, are preferred, but phosphorus pentoxide and copper and cadmium pyrophosphates are also specified.  Kieselguhr, pumice, bentonite and bauxite are specified carriers.  Granular or powdered catalysts may be used, and the latter may be suspended in the reactant stream.  The charging stock may be an olefinic naphtha or gasoline produced, for example, by catalytic or thermal cracking or reforming. Figures are given showing the effect of varying temperatures in the refining of a gasoline, obtained by catalytically cracking a gas oil, using a catalyst which is 60 per cent P2O5, 5 per cent water and balance kieselguhr.  Comparative figures when operating at low pressure in vapour phase are also given. Specifications 457,997, [Group III], 464,753 and 482,905, [Group III], are referred to.

Title: Improvements in or relating to valves for fluid pressure supply systems
IPC: F16K11/07
Filed: 1944-08-09
Abstract: 586,975. Fluid-actuated valves. BENDIX AVIATION CORPORATION. Aug. 9, 1944, No. 15177. Convention date, Oct. 20, 1943. [Class 135] In a fluid-actuated valve for dividing the flow of pressure fluid between a main outlet 52 and an auxiliary outlet 50 to maintain a predetermined flow through the main outlet, a valve member 64 is slidable in a bore 54 to control inversely the flow of fluid to them from two spaced passages 60, 62, each connected through a conduit 58 with the inlet 53, and the part of the conduit between the passages is formed with a constriction, the pressure drop across which is communicated to the valve to regulate its position. As shown, the conduit 58 is formed as a venturi tube, the throat of which communicates, via a passage 84, an annular cut-away 82 and a'passage 76 in the valve member, with a chamber 78 on the right of the valve member, whose other end 74 is coned to allow the fluid pressure in front of the venturi to act thereon at all times. The valve member 64 is normally urged to the left by a spring 70 to close the outlet 50 and open the outlet 52, but when the flow through the venturi is sufficiently great, the differential pressure between the two ends of the valve member moves it to the right to a position of balance, partially opening the outlet 50 and restricting the outlet 52. Further variations of flow rate within the range of operation of the valve will then react thereon to alter its position of balance and keep the flow through the outlet 52 constant. In Fig. 1 (not shown), the valve is applied to a motor vehicle fluid pressure system for the power operation of steering, brakes and other functions. Specification 568,921 is referred to.

A cylinder e.g. the impression cylinder of a printing-machine, comprises mechanism within its diameter for straining an impression blanket about the periphery of the cylinder and a number of grippers to grip a sheet and carry it around with the cylinder as it rotates, the grippers constituting a unit which is detachably secured to the cylinder so that the unit can be removed to expose the straining mechanism without disturbing the setting of the grippers. As shown, the cylinder 1 has recesses 2, 3 accommodating bars 4, 5 to which the ends of the blanket B are secured. The bars 4, 5 are rotatable to strain the blanket and are held in position by pawls and ratchets. The recess 2 is enlarged at 6 to receive the gripper unit which comprises a series of fingers 7 pivotally mounted on a spindle 8 secured to a supporting frame 9. The supporting frame 9 has a number of slots 12 which are engaged by bolts 10 screwing into the body of the cylinder at 11 for securing the frame to the cylinder. The fingers 7 are individually biased into contact with a seat 13 mounted on the frame 9 by springs 14 which react against brackets 14a secured to the spindle 8. Followers 16 are mounted on the rear ends of the fingers 7 and are engaged by tappets 17 for opening and closing the grippers. The tappets 17 are adjustably mounted in arms 18 secured to a spindle 19 which can oscillate in bearings in the recess 6. The spindle 19 is biased in one direction by a spring 19c and is oscillated by means of a cam follower on one end thereof which engages a cam track as the cylinder rotates. The gripper unit may be removed (the full line position, as shown) by slackening the bolts 10 and lifting the frame 9 away from the cylinder. The position of the frame 9 in the recess 6 may be adjusted so as to ensure that the outer face of the seat 13 is level with the outer surface of the blanket B by means of slides 21 which are movable substantially radially in the recess 6 by adjusting studs 22. The slides 21 have bevelled surfaces 20 which engage the inner end of the frame 9 so that movement of the slides 21 before the bolts 10 are tightened results in inward or outward movement of the frame. When the frame and seat 13 have been adjusted the bolts 10 are tightened and the slides 21 are locked by bolts 23 in a bar 24 which is secured to the cylinder and notched at intervals to receive the slides 21.

Abstract: 1,152,325. Grinding. H. I. BADAWI. 7 April, 1966, No. 15782/66. Heading B3D. [Also in Division C4] A buffing bar comprises at least two buffing compositions, each of said buffing compositions occupying one or more distinct regions of the bar, the buffing compositions comprising an abrasive material together with a fatty acid, fat, wax and/or grease. As described the abrasive material can be aluminium oxide, silica, calcium oxide, magnesium oxide, ferric oxide, tripoli powder or kieselguhr. The fatty acids, fats &c. can be stearic acid, oleic acid, palmitic acid, paraffin wax, sugar cane wax, carnauba wax, beeswax, cereals wax, fish fats, tallow or animal fats. The bar can be made by a method which comprises casting a first buffing composition into a mould and allowing the surface of said first buffing composition to solidify, casting a second buffing composition into said mould on to the solidified surface of said first buffing composition, and, if desired, casting further buffing compositions into the mould on to the solidified surfaces of the preceding buffing composition, each buffing composition being different from the preceding buffing composition. In an example 50 parts of a first buffing composition consisting of stearic acid, 20 parts; fatty acid from cotton seed oil, 7 parts; paraffin wax, 8 parts; and aluminium oxide 65 parts was cast as a layer into a metal mould and after allowing the surface to solidify 200 parts of a second buffing composition were cast as a layer on to the surface of the first composition; the second composition consisting of stearic acid, 14 parts; paraffin wax, 6 parts; animal fat, 10 parts; lubricating oil, 4 parts; aluminium oxide, 20 parts; and finely divided clay, 46 parts; all parts are by weight. Additional layers of the two compositions were then cast in turn into the mould until four layers of the first composition, separated by three layers of the second composition were provided. Two main shapes of the bars are described, one in the form of a truncated pyramid the base of which is rectangular and the other in the form of a cylinder. The different compositions can be arranged in the form of layers which in the case of the truncated pyramid form of bar can be parallel with the base, at right angles to the base, both, or in the form of wavy layers and which in the case of the cylindrical block can be parallel to the axis, at right angles to the axis or concentric with the axis. A cylindrical form is also described in which one composition is in the form of rods surrounded by another composition. In both forms one composition can be in the form of irregularly shaped particles surrounded by another composition.
