IPC: C10G49/00
Filed: 1968-09-20
Abstract: 1,213,335. Hydrogenation of oils. RALPH M. PARSONS CO. 20 Sept., 1968 [22 Sept., 1967], No. 44741/68. Heading C5E. In a high-pressure hydrogen consuming process, hydrocarbon feed material is introduced into a hydrogen consuming reactor circuit and converted to form a reactor effluent stream containing reactor products with the conversion occurring in the presence of hydrogen from a vapour stream, the process comprising the steps of (a) producing a hydrocarbon diluent from the reactor effluent; (b) combining the diluent with hydrogen at a pressure lower than the reactor pressure to form a resultant stream having an average molecular weight which enables compression of such stream by centrifugal compression to an introduction pressure which is sufficient for the resultant stream to enter the hydrogen consuming reactor circuit; (c) compressing the resultant stream by centrifugal compression to the introduction pressure; (d) introducing the compressed resultant stream into the hydrogen consuming reactor circuit; (e) separating a substantial amount of the diluent from the hydrogen; and (f) introducing the hydrogen into the vapour stream. The process illustrated in the Specification is hydrocracking but the invention is also applicable to other hydrogenation processes for treating hydrocarbons.

Abstract: 1280705 Turret lathes; indexing J L JEANNERET 11 Sept 1969 [27 Sept 1968] 44792/69 Headings B3B and B3T In a machine tool such as a turret lathe means is provided to sequentially effect the traverse, indexing and locking of a tool turret in a programmed cycle of operation. The turret assembly 1 is movable on a slide 2 by an hydraulic piston and cylinder unit 7, 14, the turret 33 being rotatably indexable in a housing on the slide 2. In operation, at the commencement of the feed stroke the piston and cylinder unit moves the turret housing on the slide 2 causing a lever 63 therein to engage a fixed cam member 72 and pivot to engage a roller plunger 47, 48 in one of the cam grooves 45a in a cam drum which is coaxial with turret shaft members 42, 32. At the same time a further lever 94 engages a further fixed cam member 105 and is pivoted to effect retraction of the turret locking bar 75. Continued movement of the assembly effects rotary indexing of the turret due to relative movement between the roller plunger and the drum groove. At the end of the feed movement the levers 63 and 94 disengage from the cams 72 and 105 respectively whereby the plunger roller is removed from the groove in the cam drum and the locking bar is urged by spring 88 into engagement with a recess in the turret to locate it in its required indexed position. The movement of the housing relative to the slide 2 is now terminated and the infeed of the cutting tool carried by the turret is effected with the lathe carriage. After machining the carriage is withdrawn and the turret assembly is returned to its initial position by the piston and cylinder unit in in readiness for the next operation. The control of the machine tool is effected from a programme and the whole sequence of operation is automatic.

In the clutch-brake shown, a rotatable shaft 11 is mounted within a stationary housing (12) and a driving flywheel 13 belt-driven from a motor. Brake and clutch discs 19, 19a are engageable with friction rings 28, 28a respectively provided on the housing and the flywheel. Chambers 27, 27a bounded by the discs 19, 19a and the housing and the flywheel, respectively, form brake and clutch vacuum-energized servomotors. The gaps between the discs 19, 19a and the friction rings 28, 28a provide for cooling air flow. The servomotors 27, 27a are in communication respectively directly, and through a bore 30 in the flywheel, with ports 29 opening, via notches 46 in rings 44, into brake and clutch valves 14, 14a mounted in the housing. Each valve comprises a valve chamber 41 provided with the servomotor-connected port 29, a vacuum source-connected port 43, and a vent port 37; a coil and core 35, 36 forming an electromagnet surrounding said vent port 37; and an iron or steel freely-floating armature disc 42 which is movable by energization of said electromagnet from a venting position in which it closes, and is held by vacuum at, the port 43 and establishes communication between the ports 29, 37, to a servo-energizing position in which closes the vent port and establishes communication between the ports 29, 43. The vacuum force acting on the disc 42 may be preselected by determining the effective opening area of the port 43 by means of the ring 44. The disc 42 may be frusto-conical to maximize magnetic flux. A passageway 16 in the housing permits lubrication of the shaft bearings and aids heat dissipation. A hard rubber lipped ring seal 25 is provided between the housing and the flywheel. Shaft bearings 24, 26 of porous bronze provide additional air sealing. Separate manually actuated switches may be used for the valves, but preferably a conventional switch simultaneously energizes the brake valve 14 and de-energizes the clutch valve 14a and vice versa. In Fig. 4 (not shown), a single valve and disc arrangement is provided for braking a loaded freely rotatable shaft.

Abstract: 1,092,909. Plywood; laminates. BORDON CHEMICAL CO. (U.K.) Ltd. Nov. 16, 1964 [Nov. 25, 1963], No. 46535/63. Headings B5L and B5N. A method for the production of laminated sheet material, such as plywood, comprises applying separately and successively to one or both of the surfaces to be bonded first a liquid resinous component and secondly a comminuted, fusible solid resinous or potentially resinous component, bringing the surfaces to be bonded together, and curing the resinous material of the combined coating under heat and pressure, both the liquid and solid components being potentially thermosetting at least in the presence of one another. The term " liquid resinous component " covers a condensation product of an aldehyde with urea or thiourea, or with a phenol which is unsubstituted in those portions of the ring which are reactive towards formaldehyde, such phenols being phenol, metacresol, 3.5-xylenol and resorcinol. The term " solid resinous component " covers products which are resinous or become resinous when heated or upon reaction with one or more of the ingredients of the liquid resinous component and are thermosetting when heated alone or in conjunction with the liquid component, e.g. condensation products of aldehyde with urea, melamine or thiourea, phenol, meta-cresol, 3.5-xylenol and resorcinol which are solid at room temperature. Preferably, both liquid and solid components are condensation products of phenol with formaldehyde, the phenol being of the resole type produced by 1 mol. of phenol with 1 mol. of aldehyde under alkaline conditions, or of the novolak type. When phenolic novolak resin or tannin extracts, such as mimosa, quebracho and wattle bark powders, are used as the powdered component, an aldehyde donor, such as hexamine or paraformaldehyde may be incorporated. In operation, the sheet material, such as wood veneer, is conveyed past a station whereat a film of the liquid resinous component is deposited by brushing, rolling, spraying or by a curtain coater in which the liquid is fed through a slot of adjustable width. The sheets are then conveyed past a second station whereat the solid resinous component is deposited by brushing, spraying or by a second curtain coater having a vibrator. If the solid component is sprayed, the particles may be electrostatically charged. Thereafter the sheets are assembled to form a laminate with the grains in adjacent veneers at right-angles and the assembly lightly pressed for 30 minutes before being placed in a press at a temperature of 115‹ C. and a pressure of 200 lb. per square inch for 6 minutes. The Specification includes a number of examples giving the quantities of constituents used in the liquid and solid components.
