Title: Improvements in or relating to the production of lubricating oils form crude oils and the like by treatment with hydrogen at high temperatures and pressures
IPC: C10G47/00
Filed: 1930-08-13
Abstract: <PICT:0352775/III/1> Lubricating oils are produced from heavy oils by passing the latter and gases rich in hydrogen in opposite directions through a deep bed of catalytic material at a temperature in excess of 700 DEG  F. and under a pressure considerably in excess of atmospheric, and separately withdrawing liquid oil and gas from the catalytic bed. Heavy oil is passed rapidly through a heating coil 4 into the top of a vertical reaction drum packed with catalytic material while gas rich in hydrogen is forced through a heating coil 6 into the base of the drum which is maintained at the desired temperature by the heat of the incoming materials or may be heated internally. Gas and such light oil vapours as are formed are withdrawn through a line 8, heat exchanger 9, condenser 16 to a separator 11 from which the gases are returned to the system through a line 13, exchanger 9, purifier 14 and pump 15.  The liquid oil is withdrawn with reduction of pressure through a pipe 18 and heat exchanger 19 to a flash tower 21 provided with heating coils 25, 24 and cooling coil 26.  The vapours evolved are condensed in a condenser 28 and separated from gases in a separator 29, while the residual oil is evacuated through a heat exchanger 36 and cooler 37 to storage.  The crude oil is preheated by passage through the heat exchangers 19, 36 and coil 26.  The catalyst comprises preferably chromium and molybdenum oxides compressed in lump form or carried on resistant materials, e.g. kaolin in brick form.  Formation of low boiling products is restricted to 5-20 per cent of the feed and temperatures of 700-825 DEG  F. and pressures of 50-200 atmospheres are specified.

Abstract: 1343640 Drying vegetable material INSTITUT DE RECHERCHES APPLIQUEES AUX BOISSONS and BUREAU ETUDES RECHERCHES EXPLOITATION DE BREVETS 19 April 1971 [27 Feb 1970 (2)] 24324/71 Heading F4G [Also in Division A2] A vegetable material in liquid or pulp form comprising 50-85% of solids in water, is dehydrated by heating by means of an ultrahigh frequency electric field of frequency greater than or equal to 850 MHz (preferably 2450 MHz), at a pressure of 1 to 20 mm. Hg. A thickener or gas may be added to the vegetable material to produce foaming of the material. The high-frequency field is produced by a water-cooled magnetron connected to an antenna radiating through a plastics window into a stainless steel oven in the form of a horizontal cylinder. The vegetable material may be an infusion, decoction, juice, pulp, or essential oil of strawberry, raspberry, blackcurrent, granadilla, orange, lemon, grapefruit, mandarin orange, clementine, coffee, aniseed, mint, verbena, camomile, balm mint or linden material. The thickener may be a carbohydrate, glucide, sucroglyceride carragheen, gum arabic. pectinate, methylcellulose, carboxymethylcellulose, or a protein (e.g. albumin), or mixtures. The liquid may be initially concentrated to increase its viscosity by means of freezing or inverse osmosis or adding dried material. The continuous or intermittent heating lasts for between 4 and 30 minutes, and is succeeded by a period in which the vacuum is maintained. The vacuum is released by introducing nitrogen into the oven and the material is cooled, broken up and packaged. The heating under vacuum may be in two stages, i.e. at below 30‹ C. and at below 50‹ C.

A fastener for use in securing together the parts of an assembly, e.g. an aircraft spinnernose, comprises a tube 3 closed at its outer-end by a cap 4, and having its open inner-end mounted on a part of the assembly with a spring 4 and screwed-bolt 5 therein, the head of the bolt being urged by the spring to force the shank of the bolt through the open-end of the tube, a nut 7 fixed in the other part of the assembly and having a helical-coil insert 8 for receiving the screwedshank of the bolt, the shank having a toolreceiving-recess 17 whereby rotation of the bolt in the nut by a tool will secure the parts of the assembly together. The tube is secured to one of the parts of the spinner by rivets 14a which pass through a seat 6 secured to the bottom of the tube. The spring 4 surrounds a guide 1 secured to the cap. When the bolt is fully engaged with the nut, its bottom is flush with the surface of the assembly. When the bolt has been unscrewed from the nut it can be pushed longitudinally against the spring until two opposite-flats 18 on the bolt-head pass beyond detents 19 on each side of the tube; whereupon a quarter-turn of the bolt causes the head to engage the detents to retain the bolt in its retracted position.

Abstract: 156,881. Pollak, J. E., (Utreclatsche Machinefabriek o.d. F. Smulders). Oct. 8, 1919. Accumulators.-Relates to quick-acting reversing trip gear operated by a reciprocating body at the ends of its stroke stated to be applicable generally and described in connection with hydraulic accumulators. The pump suction valve is operated by a counterweight 19 connected to lever 10 having a rod 13 passing freely through a hole in a lug 14 formed in a weight 8 heavier than the counterweight 19 and terminating in a head 15. A headed rod 6 mounted in the weight 8 is connected by a cord to a weight 1 which moves in unison with the moving part of the accumulator. As the weight 1 descends from the position shown in Fig 1, the rod 6 is raised. Before its head 7 contacts with and raises the weight 8, a pawl 21 is moved by a cam-surface on the weight 1, so that its end 23 engages the upper surface of a projection 24 on the lever 10. The weight 8, while being raised, slides on the rod 13. When the accumulator ram reaches its extreme position, the cam-surface on the weight 1 moves the pawl 21 out of engagement with the lever 10, and the counterweight 19 raises the lever to its upper position as shown in Fig. 3. During the return, the weight 8 is lowered, the pawl 21 being caused to lock the lever 10 in its upper position before the weight has come into contact with the head 15 of the rod 13. At the end of the motion the pawl is disengaged, and the heavier weight 8 returns the lever 10 and counterweight 19 to the position shown in Fig. 1. The projections 23 and 24 may be stepped.

Abstract: 449,059. Bobbin cradles for yarn &c. winding machines. HOLT, H., Atlas Iron Works, Whitworth Road, Rochdale. Sept. 9, 1935, No. 24997. [Class 120 (ii)] In machines for winding yarns or threads, filaments, or like materials in which the tube is driven by surface contact with a drum or in which the tube is carried by a spindle driven by surface contact with a disc or pulley, the cradle carrying the winding-spindle is adapted to be moved so as to withhold the tube or driving disc from the drum or pulley to facilitate removal of a wound package or the free turning of the package for finding and piecing a broken end, by means of a strut or arm r carrying a block s co-operating with a slot y<1> in such manner that it may prevent or permit the return of the cradle. As shown, the parts are in the stop-position, the frame e being turned about its pivot f to separate a package from its driving-drum a and to operate a package-brake k. The cradle b is pivoted at g on the frame e and is controlled by a spring l, and the slot y<1> is formed in a bracket y secured to the frame e. In normal working the block s moves freely in the straight and parallel part of the slot. The slot is formed with surfaces y<3>, y<4>, y<5> so arranged relatively to the rectangular block s that initial movement of the cradle b in the direction of the arrow A turns the block so that, in conjunction with the surfaco y<3> it acts as a stop, and further movement in the same direction effects, in conjunction with the surface y<4>, a further turning of the block s thus permitting free re-entry into the straight part of the slot y<1>. A resilient washer is fitted to prevent the strut from being moved too freely.
