Title: Bearing for vertical hydro-extractors
IPC: B04B9/12
Filed: 1946-11-13
Abstract: 624,887. Bearings. RASMUSSEN, C. 0., (trading as SIMPLEX). Nov. 13, 1946, No. 33744. [Class 12 (i)] A bearing for a vertical hydro-extractor comprises a ball or pivot resting in a bowlshaped recess, which is formed in the top of a central pillar and has a greater horizontal extent than the ball or pivot, the upper end of the pillar being resilient to lateral stresses. In the bottom of the casing 1 of a hydro-extractor is a bearing 2 in which is removably inserted a rigid pillar 3, having its lower end resting in a rubber liner 10 and carrying at its top a bearing 4, the bearing surface of which consists of a concave recess 5 having all its radii of curvature greater than the radius of a ball 7 which is seated in the recess 5 and forms the sole support of the drum 6. The recess may be partspherical or may have a generatrix consisting of a concave curve, e.g. part of an ellipse. In operation the drum is rotated at great speed so that the ball 7 moves on a circular course; as a result of friction, slight lateral stresses are imparted by the ball to the bearing 4, which makes lateral oscillations in time with those of the ball, but of smaller magnitude, owing to the fact that the pillar 3 is resiliently supported with its natural frequency of vibration below the operating speed of the drum. Because of the resilient properties of the bearing 2 and pillar 3, the casing 1 is largely isolated from vibration. The ball 7 will not make everincreasing circular movements on the supporting surface, since the bearing 4 will exert a highly dampening reaction on the lateral movements of the ball. As the lower end of the pillar 3 will make circular movements on its base, the latter comprises a hardened steel plate 8 inserted into the bearing 2 from below, the lower end of the pillar being rounded and also of hardened steel. The bearing 2 is removable, being fitted in a bayonet socket 9.

In a roller conveyer furnace having rollers with stub shafts supported in flanged bearings outside the furnace, openings for removal of the rollers are arranged on alternate sides of the furnace, and the opposite openings have a smaller diameter. The first roller 5 is mounted on shafts 7, one passing through a small opening in the furnace wall 2 to engage a flanged bearing 13, and the other passing through an opening in the opposite wall 1 large enough to allow the withdrawal of the roller 5. The withdrawal opening for the next roller is formed in the wall 2. The reduction of alternate openings in each wall of the furnace allows the rollers to be more closely spaced.

In the embodiment shown, the fitting comprises a tipping cradle K pivotally mounted on the vehicle at L, and a counterweight A mounted on a' shaft B to which is secured an arm C, the weight being held in its raised position by a spring catch E. A bin to be emptied is lifted manually on to the cradle K where it is held by hooks K<2> and a projection K\ and the weight A then released by operating a handle J to withdraw the catch E through a rod H and bolt F. During the fall of the weight to its dotted line position, the arm C is rotated anticlockwise and its roller C<1> runs along a channel in the bottom of the cradle so as to tilt this and empty the contents of the bin. The Provisional Specification describes also an arrangement in which .the counterweight is attached to one end of a cable running over pulleys on the vehicle, and the fitting is connected to the other end of the cable. Alternatively, the counterweight is connected to the short arm of a lever, and the fitting connected to the long arm of the lever by a cable.

Abstract: 957,026. Cathode-ray storage tubes. RAYTHEON CO. Oct. 4, 1960 [Oct. 28, 1959], No. 34053/60. Heading H1D. [Also in Division H4] In a signal storage tube consisting of writing gun 3, storage electrode 4, secondary electron collector 5 and reading gun 2 in which the reading beam passes through the storage electrode to impinge on the collector 5 which also serves at the output electrode, the potential difference between electrodes 4 and 5 may be adjusted to effect complete or partial erasure of the charge pattern on the storage electrode. It is stated that the potential difference between electrodes 4 and 5 governs the number of elastically scattered primary electrons emitted from the collector electrode 5, these electrons having sufficient energy to reach the storage electrode 4 where they neutralize the charges of the charge pattern. Electrodes 6 and 7 are accelerating electrodes for the respective writing and reading beams. The tube may be used to convert a television picture received at one scan rate, e.g. 60 c/s., into an equivalent picture at another scan rate, e.g. 59.9 c/s., which may be, for example, in synchronism with a local power frequency. The tube may also be used in a radar system having a P.P.I. cathode-ray tube display in which it is desired to display target history to any convenient extent.

Title: Improvements in or relating to catalysts and the hydrogenation of unsaturated hydrocarbons using said catalysts
IPC: C07C7/163
Filed: 1959-10-13
Abstract: A catalyst which may be used for the hydrogenation of acetylenes is obtained by impregnating a porous catalyst base with a solution of a nickel compound which is decomposable by the action of heat to metallic nickel, and thereafter heating the impregnated porous support whereby metallic nickel is deposited on the support and sweeping out volatile decomposition products of the nickel compound by means of a stream of gas passed over the catalyst at a flow rate greater than 250 vol./vol./hours.  The nickel compound is preferably nickel formate and the carrier may be calcium oxide, barium oxide, strontium oxide, magnesium oxide, calcium carbonate, barium carbonate, strontium carbonate, magnesium carbonate, diatomaceous earths, charcoal, graphite, pumice, deactivated alumina or sepiolite. The gas for sweeping out volatiles preferably contains hydrogen or nitrogen but may also be carbon dioxide or methane.  The purification of ethylene or propylene containing acelytenes is effected by selective hydrogenation in the presence of the above catalyst at 0 DEG -200 DEG C. and 0-1,000 p.s.i.g.  Hydrogen is supplied as such or as a tail gas from reforming steam cracking, catalytic cracking or dehydrogenation.  Specification 899,652 is referred to.

Abstract: 301,730. De Forest Phonofilms, Ltd., (Assignees of Forest, L. de). Dec. 3, 1927, [Convention date]. Combined working of optical sound-recording apparatus with kinematographs ; film - feeding mechanism.-An optical soundrecording device is adapted to be attached to a kinematograph camera of ordinary type so that combined sound and picture records can be made on the same film when desired. In the apparatus shown, the motion-picture camera, which is not of itself novel, comprises a casing 1 having a film magazine 2 detachably secured thereto, a rotatable member 4 carrying a number of different lens systems 5 being mounted at one end of the casing 1 so that " shots " of different lengths can be taken. A motor 6 drives a sprocket wheel 10 and a take-up drum 7 which are connected by a belt or chain 8. The film 11 passes from a drum 12, and is fed by the sprocket 10 towards, and away from, the usual gate 13, where intermittent motion mechanism (not shown) is provided. After leaving the underside of the sprocket 10, the film passes through an aperture in the casing 1 into the casing 28 of a sound-recording device, detachably secured at 40, 41 to the picture camera. Within the casing 28 is mounted, between adjustable bearings, a large smooth roller 18, the film passing around it, but being held in contact only with flanges thereon by pressure rollers 21. These are mounted on a spring-pressed yoke 22 which can be pulled outwardly to enable, the film to be threaded on to or taken off the roller 18 when a door in the casing is opened. The member 22 also serves, when in the normal position, to press together contacts 30 in the motor circuit, so that the motor is automatically stopped when the part 22 is moved outwards for the removal of the film. An arm 26 carries a roller, bearing by gravity or by spring pressure on the film, after passing which roller the film re-engages the sprocket 10 and is fed to the drum 7. On the spindle of the roller 18 is a flywheel (not shown) which ensures that the movement, of the film, as it passes over and drives the roller, is uniform. A tube 32, attached to the casing 28, for example by a bayonet joint, holds between spring fingers 36 the sound-recording lamp 37, and supports a slit block 34 and a lens system 33 which focusses a reduced image of the slit upon the film.
