Title: Improvements in or relating to cleats
IPC: F16G11/10
Filed: 1961-03-24
Abstract: 943,969. Clamp fastenings. F. VON OPEL. March 9, 1962 [March 24, 1961], No. 10851/61. Heading E2B. A device for securing a rope, for example, a rope from a sail of a sailing vessel, comprises a pivotal plate on which is mounted a jam cleat, the pivotal plate being held against movement by means that can be triggered to release the plate such that the pull on the rope swings the plate upwardly to release the rope from the jam cleat. In Figs. 2 and 3, the cleat comprises two eccentrics 21 between which the rope can be clamped when pulled in the direction of the arrow 26, the eccentrics 21 being pivoted on a slidable plate 23 that is held in the position shown in Fig. 2 until released by a trip mechanism permitting the plate 23 to pivot about a shaft 27 to release the rope 25. The trip mechanism includes a shaft 36 having pins 37 that engage one end of the plate 23 in a manner preventing it from moving to the right, and a fixed lip 31 that engages the other end of the plate 23. When a pivoted lever 42 is turned clockwise it strikes an abutment 41 that releases a trigger element 38 from a catch 39. The trigger element is coupled to the shaft 36 via a trigger lever 35, and the release of the trigger element 38 means that the pins 37 can now be pushed away from their locking position by the force exerted by the rope 25 on the plate 23. As the plate 23 moves away from the lip 31 the pull of the rope 25 causes the plate 23, and the eccentrics 21 thereon, to rock upwardly about the shaft 27 and thus release the rope 25 from the eccentrics. The lever 42 carries an upper weight 45 which, if the cleat is mounted on a vessel that rolls too far to the right, can pass an upper dead centre whereafter it causes the lever 42 to strike the abutment 41 to release the rope 25. In Fig. 1, if the lever 10 swings from the full line position to the position shown in broken lines the arm 8 moves anticlockwise thus withdrawing a catch 9 from the plate 1. The plate 1, and the eccentrics 2 thereon, then pivot upwardly about the hinge 5 due to the pull on the rope 4 and this causes the rope 4 to be released.

A cylindrical conduit 32 located coaxially within the container 18 is closed at its lower end by a plate 68 and at its upper end by a deflector 66 which serves to direct heated liquid sodium &c. entering the pressure vessel through a diffuser conduit 64 into the annular space 34 between the conduit 32 and the container 18. The liquid sodium is maintained at a level 86 within the container 18 by regulating the pressure of inert gas admitted through an inlet 76 to fill the spaces 24, 26, 28. Water to be vaporized enters a header 52 from which tubes 54 convey it into the annular space 34 wherein the tubes are formed into a concentric series of helical coils 40, the generated steam flowing from the coils by way of pipes 58 to an outlet header 60. All the coils 40 are made from identical lengths of tube by increasing the coil pitch with the coil radius so that fluid passing through different coils receives the same amount of heat from the sodium &c. in which the coils are immersed.

IPC: C01B33/18
Filed: 1964-03-17
Abstract: Metal oxides and silica are prepared by a process comprising introducing streams of metal halide vapour and oxidizing gas separately into a fluidized bed through the base of a reactor containing the bed, there being at least one metal halide vapour stream and at least one oxidizing gas stream the directions of whose paths as they enter the bed intersect in the bed and whose velocities as they enter the bed are such that the two streams impinge upon each other within the bed.  The oxides may be titanium dioxide, alumina, ferric oxide, zirconia and silica.  The oxidizing gas may be oxygen or free-oxygen containing gases such as air, and also water, hydrogen peroxide or oxides of nitrogen. The bed may be of particles of size 50-2000 microns and may consist, of silica, alumina, zirconia, zircon sand, titanium dioxide or mixtures thereof.  Other gases, e.g. nitrogen may be employed to assist fluidization of the bed.  The bed may be heated with an external source such as by burning a fuel, e.g. propane within the bed or by preheating one or both of the reactants. The reactants are introduced at a velocity of at least five feet per second. Additives may be introduced with the reactants, e.g. in the case of titanium dioxide, aluminium halides, silicon halide, water vapour or a hydrogen-containing gas which is converted to water within the bed, zirconium halides, lower halides of titanium, a source of an alkali metal such as potassium, rubidium or caesium and/or thorium.  Particles of weight media crystal size below 0.25 microns or 0.20 microns may be produced.  The hot gases leaving the bed containing oxide particles are passed to an upper zone maintained at at least 600 DEG  C. into which additional amounts of the metal halide and/or oxidizing gas may be introduced as described in Specification 991,318.

Title: Improvements in the mechanical treatment of materials
IPC: B03B1/00
Filed: 1954-04-21
Abstract: In wire drawing, drilling, turning, milling, grinding, crushing or otherwise cutting or plastically deforming material, e.g. metals, silica or silicates, the operation is assisted by the supply of a vapour or aerosol of a substance facilitating the breaking up or alteration of the surface of the material, e.g. benzene, acetone, carboxylic acids, alcohols, amines and inorganic substances with complex molecules and a tendency to form polymolecular compounds such as phosphorus acids and sulphur compounds.  The use of active substances in vapour or aerosol form is said to avoid the use of wet working and the pretreatment of the work with a lubricant.  Where possible the vapour or aerosol is supplied so as to surround the material being worked e.g. in the form of a jet directed at the cutting operation or to the interior of a ball mill during a comminuting operation.  In an example, benzene or acetone is supplied at 80 DEG C. to a drum mill and recovered by passing the exhaust gases through water cooled separators.
