Since liquid enters the slots from the high pressure port 13 across the tips of the gear teeth, Figs.4 and 6 (not shown) the velocity of the liquid issuing from the low-pressure ends of the slots is insufficient to cause erosion. It is indicated that adjacent bushes may be combined in a single piece, separate bushes to support the gears may be provided and communication between the highpressure side and each slot may be through a flowrestrictor in a duct formed in the casing or respective bush. The invention is said to be applicable to other axially pressure-balanced rotary positivedisplacement hydraulic machines having meshing rotors.

Abstract: 1,262,923. Coating pipes. CONTARDO S.p.A. 30 Jan., 1969 [31 Jan., 1968], No. 5172/ 69. Heading B2L. [Also in Division F2] A double acting piston 21, Fig. 3, slidable upon a fixed pin 22 within a cylinder 20, has a hollow ended stem slidable within a fixed sleeve 24 formed at its outer end with apertures 23 which are closed by the stem of the piston 21 when the latter is shifted to its left hand end position by the admission of fluid into cylinder 20 through port 28. The end of a tube 26 is then positioned on pipe 22 within the hollow end of the stem of piston 21 and the latter is then moved rightwards by fluid admitted through post 31. The apertures 23 are thereby uncovered and adhesive passes therethrough from the annular space 29, fed under pressure by pipe 30, on to pipe 26 where it is spread to a desired thickness by a ring member 25 when the pipe is withdrawn. For coating the internal surface of a pipe the adhesive is supplied through a stem 34, Fig. 2, over which the piston slides and the end of which, carrying a spreader 37, is inserted in the pipe. Movement of the piston to the right opens windows 36 in the stem through which the adhesive flows on to the pipe surface, on which it is spread by spreader 37 when the pipe is withdrawn. The apparatus is used for coating the exterior surfaces of two ends of a U-pipe and the internal surfaces of straight pipes to be joined together by the U-pipe, the latter being held by a block and hammered into position.

Patent GB-703491-A (GB)
Title: Improvements in or relating to production of oxygenated compounds from olefins
IPC: C07C29/16
Filed: 1951-03-06
Abstract: Oxygenated products comprising aldehydes are obtained by contacting olefinic compounds, carbon monoxide, water, and hydrogen in an initial reaction zone with an iron group preferably a cobalt carbonylation catalyst at elevated temperature and pressure, passing the reaction mixture via a cooling zone to a gas-liquid high pressure separating zone where water and water-soluble cobalt compounds are separated from other liquid products and uncondensed gases, recycling at least a part of said water and water-soluble cobalt compounds to said initial zone thus maintaining a high concentration of active catalyst there and providing cooling, and passing the other aldehyde-containing liquid products to a decobalting zone where the cobalt catalyst is converted by heat treatment to insoluble cobalt compound and separated.  Water is initially injected into said zone, but the flow of extraneous water may be cut back as reaction proceeds.  The recycled water containing cobalt catalyst may be injected into the initial zone in the vicinity of the olefinic compound injection point and also at a plurality of points spaced in the direction of flow of said reaction products through said zone. In one modification, the cooled product stream, after separation only of uncondensed gases, may be passed to the lower portion of a liquid-liquid separating zone of which water fills at least the lower half, where water-soluble cobalt compounds are scrubbed out, and water from this zone is recycled to the initial zone.  In a further modification the whole liquid product may be passed to a decobalter where the conditions are such that the cobalt catalyst in both phases is converted at least in part to other water-soluble cobalt compounds, e.g. cobalt formate, followed by separation of water and other liquid products.  The usual olefines and catalysts are referred to.

Abstract: 1300822 Making combustible gas CONSOLIDATED NATURAL GAS SERVICE CO Inc 5 Feb 1970 [11 Feb 1969] 5522/70 Heading C5E [Also in Division C1] A continuous steam-iron process for making a fuel gas containing hydrogen and methane comprises contacting a generally downwardly moving stream of particulate iron oxides with a similar stream of carbonaceous solids in a reduction zone in the absence of molecular oxygen-containing gases, so that the iron oxides are reduced and the carbonaceous solids partially depleted in carbon. The reduction zone is heated by partially burning the partially carbon-depleted solids in a combustion zone, and returning the solids to the reduction zone to supply the heat required for reduction. Carbonaceous solids are added to replace those consumed in the process. The reduced iron oxides are then reacted with steam in an oxidation zone to produce hydrogen and methane and oxidized iron oxides are recycled to the reduction zone. The reduced iron oxides and the carbon-depleted carbonaceous solids from the reduction zone may be separated in a separation zone. The oxidation zone may comprise one or two fluidized beds.
