Title: Internal combustion engines
IPC: F02F1/42
Filed: 1965-04-09
Abstract: An air inlet duct, leading from a lateral surface 1 of a cylinder head, and a chamber 12, to which the duct leads, are shaped to promote swirl of the air admitted to the cylinder. At its downstream end the duct centre line 18 veers away from the extended cylinder radius 9, which is perpendicular to the line joining the inlet and exhaust valve axes 4 and 10 respectively, and passes the inlet valve axis 4 on the side thereof remote from the cylinder axis 6. The outer (with respect to the cylinder axis) wall 14 of the chamber 12 is a smooth continuation of the duct, and from this wall 14, the upper chamber wall 13 slopes helically to the inner side of the chamber and towards the cylinder. The cross-section of the duct, from its upstream end, is rectangular with rounded corners and decreasing in area in a downstream direction until on the line VII-VII it becomes that of a right-angled triangle with rounded corners. The inner wall of the downstream end of the duct intersects the chamber 12 between the inner wall thereof and the inlet valve axis 4. This line of intersection, which is helical, is tangential, at its end remote from the cylinder, to a bore 23 which receives the inlet valve guide 24. A combustion chamber, Fig. 3 (not shown), formed in the piston either concentrically or eccentrically therewith, receives a number of fuel streams 30 from an injector 31 located in the cylinder head either concentrically or eccentrically with the combustion chamber or the cylinder.

Title: Apparatus for effecting the harmonic analysis of a function
IPC: G06J1/00
Filed: 1965-04-22
Abstract: In an apparatus for carrying out the harmonic analysis of a function f(x) continuous over a range of interest -A to +A, values of the function are stored in a digital store forming part of function generator 4, which also includes a digital to analogue converter. A reference clock 5 produces control signals for sequentially reading out the store at a number of frequencies, related to the range A, determined by the frequency divider 7. Time varying functions F k (t) = f(tA/ K#o ) are thereby produced in sequence at the output of the function generator 4, where 1/2# o is the fundamental frequency of the function F 1 (t). These functions are sequentially passed through a filter 11 tuned to the frequency 1/2# o to derive the harmonics of the input function in sequence. The filter may be a synchronous demodulator.

Patent ES-354696-A1 (ES)
Title: Improvements relating to the treatment of fabricated articles
IPC: B23P17/02
Filed: 1968-06-05
Abstract: A manufactured article has burrs, flash or other objectional projections removed from its surface by placing the article in a gas-filled enclosure and generating a transient elevated temperature in the gas which serves to remove the projections and leave the rest of the article unaltered. The projections may be macroscopic, e.g. flash, or microscopic, e.g. surface irregularities. The article may be made of a plastics, metal, e.g. steel, copper, brass, aluminium, iron or alloys, glass, cermets or ceramics. The temperature rise may be produced by adiabatic compression, shock wave generation, or ignition of combustible gases. A heat mask may be provided in the form of a metal heat sink or a polythene coating over the parts not to be removed. In one embodiment for a steel article 10, the article is placed in a chamber 19, Fig. 4, and a hydrogen-oxygen mixture compressed therein by a piston 20 moved hydraulically, pneumatically or mechanically. A spark plug 27 is fired to ignite the mixture and the rise in temperature serves to remove flash 12a, 13a, 14a from bore holes 12, 13, 14. An oxide residue on the article is removed by hydrochloric acid. Alternatively the combustible gas is a mixture of Texas natural gas (90% methane) and oxygen. The same apparatus may be used for other materials using a lower temperature by using different gas mixtures and pressures. The chamber may have a fixed cover and a separate piston-cylinder assembly, Fig. 5 (not shown). The combustible mixtures are of oxidizable materials and oxidizer materials. The oxidizable materials are alkanes, alkenes or alkynes, ammonia, hydrazine, hydrogen sulphide, carbon monoxide, acetylene, ethylene oxide or cyanogen. Suitable oxidizer materials are oxygen, air, fluorine, chlorine, ozone, perchlorates or nitrogen oxides. The mixture may have an excess of oxidizing material particularly when used with ferrous articles. Alternatively the mixture may have an excess of reducing material when used with non-ferrous metals. The mixture may have glass, metal, ceramic or plastics beads which are violently disturbed by the combustion and serve to dislodge the flash. In a further embodiment the article 42, Fig. 7, forms part of the enclosure and a lower closure plate 45 has a gas inlet and a spark plug 46. The gas mixture may be ignited by the compression in the chamber or a shock wave produced by an explosive cartridge or electric arc may heat the gas. In a further embodiment the gas mixture is adiabatically compressed. Figs. 10-12 (not shown), by a piston 54 moved forward by hydraulic, pneumatic or mechanical means or by detonation of a gas mixture behind the piston The gas which is compressed is preferably inert. Alternatively the gas may be combustible and ignited by auto-ignition due to the compression.

Title: Improvements in and relating to Containers
IPC: G21F5/12
Filed: 1968-10-08
Abstract: A container for transporting spent fuel elements to a vessel 2 comprises a tube 3 closable at its lower end by flaps 11 pivoted to the tube at 12. The flaps 11 are normally held in the closed position, Fig. 1, by pins 14 engaging notches 15 formed in the pivoted ends of the flaps, these pins being carried by a sleeve 8 slidable on the tube 3. The container is carried by a tongs 1 which grips two half-shell members 7 each mounted on a cranked lever 21 pivoted to tube 3 at 5. One arm of each of the levers slidably extends through a bush 18 pivotally mounted on a sleeve 4 slidable on the tube 3. To load the container it is transported by the tongs 1 to a support 19 whereby on release of the tongs a plate 20 attached to the sleeve 4 causes the latter to move upwardly on the tube 3 and the members 7 are moved to the Fig. 2 position. After loading the container it is released from the support 19 so that the sleeve 4 moves down the tube 3 and the levers 21 bring together the members 7. The container is then lowered by the tongs 1 on to the vessel 2 whereby the top of the vessel raises a flange 9 attached to the sleeve 8 so that the pins 14 leave the notches 15 and the flaps 11 drop to the open position, Fig. 3. On subsequently lifting the container the flaps are reset in the closed position by the engagement of a lip 17 on the vessel with a protruding surface 16 on the flaps.
