Title: Hydraulic reversing device for reciprocating part of a machine
IPC: F01L25/02
Filed: 1969-06-06
Abstract: 1,245,703. Hydraulic reciprocating motors. HYDREL A.G. June 6, 1969 [June 19, 1968], No.28786/69. Heading F1A. The distributing valve 6 controlling the alternate supply and exhaust of oil through lines 9a, 9b to the cylinder chambers 10a, 10b of a receprocating piston motor is caused to changeover by oil displaced by plungers 13b, 14b depressed at the end of each stroke by cams 11a, 12a movable with the piston 10d. Each plunger 13b or 14b is slidable in a respective cylinder having an overflow pipe 15, 16 cut-off on depression of its plunger, so that oil in the cylinder-is displaced through a line 17 or 18 to cause the distributing valve 6 to changeover. Oil displaced through, say, line 17, passes to a chamber 6h in the valve 6 causing movement of valve spool 6l to the right. This movement progressively decreases the output from a pump 3 passing through the line 9b to the motor. When the valve spool reaches a position uncovering a chamber 6f, the spool is moved fully to the right by pump pressure communicated thereto through throttle 22 and line 23. The chambers 6f , 6g are permanently connected to pump pressure through lines 23, 24 whereby their respective lines 17, 18 when in communication therewith are flushed with oil. An auxiliary pump (29) feeding through a second changeover valve (31) may be provided, Fig.4 (not shown) whereby slow speed operation may be effected with the valve 6 and the pump 3 inoperative.

Abstract: 862,307. Salting fish; injection apparatus. DYEKJAER, J. C. C. Dec. 7, 1959 [Sept. 8, 1958], No. 28807/58. Class 49. A machine for salting fish (Fig. 3) comprises a pump 11 which carries supersaturated salt solution from a storage tank 12 having a stirrer 16, through a filter 10, a threeway valve 9, a conduit 8 and a tube 7 to a distributing chamber 1 equipped with stirrers 3 and having cannula needles 2, with acute-angled ends, located in its base which penetrate and inject the salt solution into fish placed upon a perforated conveyer belt 21 located between the needles 2 and a support 18 provided with wheels 19 running on rails 20. The distributing chamber, needle assembly and a motor 6, which drives the stirrer 3 through a belt 5 and pulley 4, are together pivotally suspended on a shaft 17 mounted on the support 18 and in operation are lowered so that the needles 2 penetrate the fish, the assembly moving at constant speed along with the conveyer belt 21 and being thereafter lifted and returned to inject a fresh batch of fish placed on the conveyer belt 21 in the meantime. A scraper 23 actuated by springs 24 prevents fish being lifted from the conveyer belt and whilst the assembly is being lifted and returned, the salt solution is bypassed through the valve 9 and a pipe 13 to the storage tank 12; or, alternatively, the distributing chamber on return may be adapted to inject fishes on a conveyer belt moving in a direction opposite to the first. The apparatus may also comprise several distributing chambers. In the embodiment shown (Fig. 5), the distributing chamber consists of a rotatably mounted cylinder 30 the whole surface of which is provided with needles 2 which penetrate and inject fish placed on a conveyer belt 38 which advances at a speed equal to the peripheral speed of the cylinder 30.

Abstract: 1,185,576. Phenolic resins; compositions. KOPPERS CO. Inc. 17 June, 1968 [23 June, 1967], No. 28834/68. Heading C3R. A fusible, water soluble phenolic resin is made from phenolic material consisting of 50 to 90 mole per cent of phenol and 50-5 mole per cent of resorcinol and 0À55 to 0À75 moles of formaldehyde per mole of phenolic material by (a) reacting the phenol with the formaldehyde at an initial pH of 8À5 to 9À0 in the presence of 0À04 to 0À09 moles of an alkali metal sulphite or bisulphite per mole of formaldehyde, (b) refluxing the reaction mixture to a constant viscosity of 22À7 to 50 poise at 23 C., (c) adding to the reaction mixture the resorcinol and 0À006 to 0À060 moles per mole of formaldehyde of CaO, Ca(OH) 2 , or CaCO 3  and (d) continuing reflux to a constant viscosity of 200 to 400 Gardner seconds. The alkali metal sulphite may be sodium sulphite. An adhesive resin may be prepared by diluting the product to 3À0-4À3 poise viscosity and 40 to 60% solids content, adjusting the pH to 7À5 to 8À9 with aqueous caustic soda and optionally adding a filler. Diluents specified are mixtures of methanol, ethanol, ethyl acetate, ethylene glycol, aviation gasoline and water. The resin may be cured with paraformaldehyde or alpha- or beta-polyoxymethylene prepared by heating paraformaldehyde in the presence of a Lewis acid, e.g. oxalic acid, and colloidal silica. Sufficient curing agent is used that in total 1 to 2 moles of formaldehyde residues are present in the cured resin per mole of phenolic material. In examples the resin is prepared in a vessel fitted with a stirrer and recirculation pump (I), the Ca(OH) 2  is added slurried with water (I) and the fillers are wood flour and walnut shell flour (II). The adhesives are used to laminate Douglas Fir and Southern Pine into plywood.

Title: Means for sampling and delivery of gas
IPC: G01N1/22
Filed: 1925-11-17
Abstract: 243,028. Trade, Board of, and Boys, C. V. Nov. 17, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Holders.-In apparatus for testing the calorific value of gases the gas bell is counter-balanced and provided with time-governed mechanism controlling the rate of flow of gas to the bell. The bell b is supported in an annular water trough formed by an outer cylinder r which covers the bell and an inner cylinder a closed by a plate j. The bell is counterbalanced by a main weight c and subsidiary weights c<1> and by making the chain d of mass proportional to the buoyancy of the bell wall. An overflow trough f receives water through holes h. The volume of the gas is measured by a scale s and the temperature by a thermometer t. When the gas is allowed to flow from the bell to the burner under pressure the bell is suspended from a pair of weights by a chain passing over a pulley v loosely mounted on a shaft y turned by a wheel 3 of the clock mechanism. The pulley is provided with clutch mechanism, e.g. a clutch star 4 and balls 5, 6 and has a rachet engaged by a three-armed detent lever 11, Fig. 2, one arm of which is operated by a cam 10 on the clock arbor 9. A catch 13 permits the lever 11 to be held free from the ratchet teeth. The rate of collection of the gas may be varied by mounting a pair of eccentric wheels between the clock and pulley shafts.
Patent GB-740619-A (GB)
Title: Method of preventing delay in boiling viscous liquids
IPC: B01J19/00
Filed: 1952-11-17
Abstract: Delayed ebullition is prevented in concentrating and sterilising viscous liquids by subjecting a restricted part of the liquid to local heating so as to produce vapour nuclei in the mass of the liquid without heating the mass of the liquid to its boiling point, the mass of liquid is then heated uniformly to produce ebullition. The vapour nuclei may be retained in the liquid for a long period (several hours) due to the viscosity of the liquid.  A liquid which is insufficiently viscous for the method to be carried out directly is thickened by evaporation of the solvent at a temperature below the boiling point.  The method may be used to prevent bumping during boiling viscous liquids in ampoules.  A gas flame is held to the ampoule for a brief time; and thereafter the ampoule is heated uniformly in a drying chamber.  This method may be used for the concentration of an aqueous solution of the sodium salt of N-methyl - cylohexanyl - methyl - barbituric acid whereby a loose foamy skeleton, rather than a powder, is obtained in the ampoules.  The treatment of a sugar solution and also of an aqueous solution of kallikrein stabilised with polyvinyl pyrrolidine, is referred to.ALSO:The circulation hormone kallikrein is stabilised by means of polyvinyl pyrrolidine during concentration or sterilisation of its aqueous solution.  Bumping of the solution is prevented during the treatment by holding a gas flame to the container for a brief time prior to raising the liquid to the boiling point, whereby vapour nuclei are formed in the mass of the liquid; the container is then heated uniformly in a drying chamber to produce ebullition.

As shown (Figs. 5, 6) a four-stage converter comprises a pressure vessel 21 in which a drum 24, divided by partitions 44 into a plurality of catalyst-containing compartments 43, is rotatably mounted, the vapours and regenerating medium being fed to and discharged from the vessel through a pair of stationary manifolds 22, 23 and sealing means indicated generally at 70 being provided to co-operate with the partitions and divide the drum and the manifolds into four gas-tight <PICT:0652835/III/1> <PICT:0652835/III/2> <PICT:0652835/III/3> chambers, three for a three-stage reaction and one for regeneration of the catalyst. Reactant vapours are passed through line 7 (Fig. 2), heater 2 and line 8 to the first reaction chamber, then through line 9, heater 3 and line 10 to the second reaction chamber, and then through line 11, heater 4 and line 12 to the third reaction chamber from which the reaction products are finally discharged.  Regenerating medium, e.g. air, is passed through heater 5 and line 14 to the regenerating chamber and is discharged through lines 15, 16 to the atmosphere or is recycled through heater 5.  Rotation of the drum brings each chamber successively into communication with the regenerating medium. Means are provided to permit equalization of pressure within the drum, manifolds and vessel.  Compression springs 62 (Fig. 5), serve to press the manifolds against the ends of the drum.  The catalyst containers comprise concentric tubular wire screens 47, 48 between which the catalyst is retained, reactant vapours passing from the outside 47 to the inside 48 and regenerating medium passing in the opposite direction.  The converter may be employed for cracking hydrocarbons employing an alumina on silica gel catalyst or for hydroforming and reforming reactions.
