Filed: 1952-07-24
Abstract: 707,128. Filleting fiat fish. DYEKJAER, J. C. C. July 24, 1952, No. 18805/52. Class 28(2) In shaving fillets off the bone of flatfish both sides at once by pulling the fish tail first between two pairs of closely spaced rotating filleting knives 1 whereby the bone passes clear through the knife spacings, the fish is presented close to the knives by pairs of guide fingers 2 which are spring urged towards each other to press on the top and underside of the fish. To allow the tail clamp 3 to pass, the pairs of knives and their corresponding guides 2 are swung horizontally apart away from the centre line of the machine. This is done by a cam frame 17 preceding the tail clamp 3 and forcing apart cam rollers 15, 16 and attached arms 10, 11 which carry the knives 1, the arms thereby pivoting apart about centres 5 and 5<1>. The brackets 12 carrying the guides 2 are coupled thereto to partake of this movement apart. After the clamp has passed a spring 18 pulls the knives and guides respectively towards each other until they are stopped at their correct spacing by stops 25. The knives remain geared together through gears 6, 7, 8 and 9 to rotate continuously. The guides 2 can yield apart vertically to accommodate the thickness of the fish. Springs 24 for each top and bottom guides geared together at 19, Fig. 5, allow this yield and keep the guide pressing on the upper and lower flats of the fish.

Title: Improvements relating to gear generating machines and index mechanism therefor
IPC: B23F23/08
Filed: 1965-05-07
Abstract: 1,068,785. Indexing. GLEASON WORKS. May 7, 1965 [June 8, 1964], No. 19386/65. Heading B3B and B3L. An index mechanism comprises a pawl 52 to engage equally spaced formations in an indexing plate 51, and reversible drive means for driving the plate in one direction only, the means enabling a fraction of a turn or several turns to be made and being co-ordinated with movement of the pawl. The mechanism is part of a gear-cutting machine having a tool cradle 2 and a work-spindle 5 as described in Specification 1,066,692. A driven shaft 7 carries a cam 8 to actuate the generating train, a cam 13 to feed the work and a cam 9 to actuate a reversing valve 11 controlling the indexing mechanism. The generating train includes ratio-of-roll change gears 26 and differential gears 31-33. The pawl 52 is axially adjustable on a bellcrank 54 to enable different plates 51 to be fitted, the pawl then being held clear by an eccentric 64. The pawl is engaged by a spring 57 and released by a piston 58. The plate 51 is rotated by a fluid-pressure motor 66 driving through a toothed belt 69 and a threaded shaft 71. When the cam 9 operates the valve 11, the pawl 52 is withdrawn, the motor 66 starts to rotate and a clutch 73, 75 is engaged by a spring 83 on release of fluid-pressure from a piston 81. The plate 51 is thus rotated at a rapid rate until a nut 86, now travelling along the screwed shaft 71, operates a valve 98 to restrict exhaust from the motor 66 to flow through a throttle 103. The nut 86 continues to move slowly until a dog thereon engages a dog on the clutch part 75 to cause the motor 66 to stall. The travel of the nut, which can be adjusted, thus determines the degree of rotation imparted to the plate 51. The pawl is then engaged with the plate, movement of the pawl enabling fluid to be supplied to disengage the clutch 73, 75.
Patent GB-685726-A (GB)
Title: Improvements relating to processes for the manufacture of aqueous ammonium nitrite solutions
IPC: C01B21/50
Filed: 1950-08-03
Abstract: Aqueous ammonium nitrite is produced by absorbing gases containing approximately equimolecular proportions of NO and NO2 in a concentrated aqueous solution, i.e. a solution the concentration of which on the CO2 content corresponds at least to a saturated bicarbonate solution, of ammonium carbonate-bicarbonate, the concentration of the solution being maintained during the absorption. Nitrous gases, from the combustion of 11 per cent by volume gaseous ammonia and air at about 700 DEG C over a platinum-rhodium catalyst, are passed in contact with a saturated absorbing solution, with stirring, at about 0 DEG C, while the concentration is maintained by having solid bicarbonate in the bottom of the container.  The resulting solution is evaporated at below 30 DEG C to give concentrated ammonium nitrite.  A suitable mixed solution contains 10-50 per cent bicarbonate and 90-50 per cent carbonate and has a pH 8.3-8.9.  A continuous absorption may be carried out by continuous addition of concentrated carbonate-bicarbonate solution, which may contain free ammonia, to the absorbing solution.
