Title: Process of hydrocracking hydrocarbon oils
IPC: C10G47/00
Filed: 1961-03-15
Abstract: In the hydrocracking of petroleum hydrocarbons, contaminated with naturally occuring nitrogen compounds, in the presence of a Group VIII metal on an acidic cracking catalyst support at 260 DEG -538 DEG C. and 34-204 atmospheres, the feed is first hydrofined to a nitrogen content of less than 1 p.p.m. by contact with excess hydrogen and a catalyst comprising a Group VI metal and an iron group metal supported on a refractory metal oxide at 315 DEG -482 DEG C. and 34-204 atmospheres and separating the ammonia formed. In the hydrofining suitable space velocities are 0,5-2 vol./vol./hr. Ammonia is removed by washing with acid or stripping with an inert gas, e.g. hydrogen, natural gas, carbon monoxide, nitrogen or flue gas ammonia is removed from the stripping gas and recycle gas by contact with acid. Cracking is effected in the liquid phase using 89-534 normal litres of hydrogen per litre of feed. The cracking catalyst preferably contains a platinum metal if an iron group metal is used molybdenum is preferably also present as the metal or as molybdate or thiomolybdate.

Patent ES-344961-A1 (ES)
Title: Wear compensating wedge for pivot joints
IPC: F16C11/06
Filed: 1967-09-12
Abstract: A wear compensating unit for pivot joint assemblies comprises, in one embodiment (Figs. 1 and 3), a wedge unit 25 consisting of a bearing member 26 and a wedge member 27, the bearing member having a stop face 28 with a concave portion 29 for seating the end 20 of a stud 13. The wedge member has shoulder portions 37 and 38 out of which extends two integral flexible arms 39 and 40, the arm 39, in the unloaded state, terminating radially inward from the arm 40. During assembly of the pivot joint 10, the wedge unit is installed in the housing 11 in its compressed state and, as the use of the joint creates wear, the spring arms 39 and 40 force the wedge member away from the back wall 32 of the bearing member and increase the height of the unit, to take up any looseness caused by wear. In a further embodiment (Figs. 5, 6 and 7, not shown), a coil spring is placed within a bore, the spring bearing against the back of the wedge member to supply force to push the wedge member away from the back of ithe bearing member. In another embodiment (Fig. 9 and Figs. 8 and 10), the wedge member 65 is formed integrally with a bearing member (66) through a relatively narrow resilient strap 67 with its inclined face 68 on one side of the strap, while the bearing member is formed with its seating face 69 on the either side of the strap. The wear compensating wedge unit 64 is assembled by bending the strap into a U-shape position (Fig. 10, not shown). In yet a further embodiment (Figs. 11 and 12, not shown), the bearing member is integrally connected with the wedge member by two resilient side legs.

Title: Ligating hemostat
IPC: A61B17/82
Filed: 1968-01-09
Abstract: A haemostat is loaded with a surgical ligating device in which a surgical ligature extends through openings in a locking member 1 to form a running noose 10 which can be closed around a severed blood vessel 60 by pulling on a draw portion 11 of the ligature, the haemostat comprising a pair of arms 12, 14 connected by a pivot 16 so as to provide jaws 18, 24 with gripping surfaces which can be closed about the blood vessel, there being a projection 54 extending from the haemostat and to which the noose of the ligature is secured, the draw portion 11 of the ligature passing through a passageway 32 in one of the jaws so as to extend between the locking member and the projection 54 around which the draw portion is also looped, the draw portion extending from the projection to anchoring means on one of the arms to form a loop, the noose being capable of being freed from the projection by pulling on the loop. As shown, projections (52), 54 are formed at each end of the pivot 16 and the end of the draw portion is secured within a sheath member 40 to the arm 14. In use, the haemostat is applied to clamp the blood vessel, and the draw portion 11 and the sheath 40 are then pulled (Figure 6, not shown) so that the noose 10 moves up and off the ends of the haemostat and is tightened around the blood vessel. The haemostat is of glass-filled polystyrene material and the passageway 32 in the gripping part 24 may be provided with a metallic insert 34 which may be used (Figure 7, not shown) to cutoff the draw portion after the noose has been tightened. The sheath member may be replaced by an adhesively applied coating.

Abstract: A method of electro-plating an object at least the surface of which consists of U, Pu, U-base alloy or Pu-base alloy (e.g. a rod or plate intended to serve as nuclear fuel) comprises the successive steps of electro-depositing a layer of a metal (e.g. Ni or Cu) which adheres to the surface of the object electro-depositing at least one layer of Sn, Zn, Pb or In mechanically surface flattening the surface whereby the pores and/or surface irregularities are closed, a smooth outer surface is obtained and the Sn, Zn, Pb or In is rendered impervious to outside agents, the total thickness of the plating after flattening being greater than 55 microns. In an example a plate of U-base alloy is (a) degreased and pickled by degreasing with trichloroethylene, electrolytic degreasing in a solution containing a wetting agent and 40 g/1 NaOH at 5 to 10 A/dm , pickling with HNO 3 , HCl and then HNO 3 (b) electrolytically plated with 40 to 50 microns of Ni by electrically connecting it as a negative pole followed by dipping it in a bath containing nickel sulphate and chloride and KA1(SO 4 ) 2 . 12H 2 O at 45 C. and at a pH of 3 0À25, the current density being progressively increased to 2À5 A/dm2 (c) washed, dried weighed, thickness measured and surface irregularities removed (d) heat-treated to enhance the adhesion of the Ni (e) retouched to fill in any flaws in the Ni layer by electrolytic "spot" deposition of Ni or Sn (f) prepared for Sn plating by electrolytic degreasing in an alkaline bath (g) electrolytically plated with 40 microns of Sn by dipping it at low voltage in a bath containing Na 2 SnO 3 .3H 2 O and NaOH at 70 degrees and increasing the current density to 2À5A/dm2 (h) washed, dried, surface irregularities removed by electrolytic spot deposition of Sn followed by buffing or polishing and (i) mechanically flattened by rotary brushing, the brush may contain a fine grit abrasive.

Title: Metal casting apparatus with electromagnetic nozzle
IPC: B01F33/40
Filed: 1972-10-10
Abstract: The fluid switch controls the flow of a liquid from a funnel shaped receptacle and causes mixing of the liquid when the switch is in a "closed" position. The switch includes an air nozzle which extends into the receptacle and opens at a point adjacent a bottom outlet opening of the receptacle. The nozzle is adapted to direct an air stream toward and through the outlet opening to pre-empt liquid flow therethrough. A greater amount of air than is necessary to pre-empt flow of liquid through the outlet opening may be directed at the outlet opening so that the excess air bubbles through the liquid causing turbulence and mixing of the liquid prior to the "opening" of the switch.
