Title: Improvements relating to the treatment of fabricated articles
IPC: B29C37/00
Filed: 1969-06-10
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.

Patent ES-449040-A1 (ES)
Title: Breathing apparatus
IPC: A62B7/00
Filed: 1976-06-10
Abstract: Breathing apparatus is disclosed in which a selected portion of each exhalation is returned to the inlet side for rebreathing. The percentage of each exhalation rebreathed varies from exhalation to exhalation and is determined in accordance with the detected magnitude of the preceding inhalation. Breathing mixture is withdrawn by the user from a reservoir which is in communication with a cylinder having a spring loaded piston therein. The pressure in the reservoir, and hence in said cylinder, at the end of each inhalation determines the position of the piston. A chamber receives the exhaled breath and expands to a degree dependant on the position of the piston. Once the chamber has expanded to the maximum extent permitted for that exhalation, the remainder of the exhalation is discharged from the apparatus.

Patent ES-480508-A1 (ES)
Title: Low noise and wear machine for forming lollies - has three-part cylindrical mould comprising a slotted rotating drum as lower half and blocks linked to form chain as upper half
IPC: B30B11/18
Filed: 1979-05-11
Abstract: Lollies are formed by compressing a piece of lolly-material in a cylindrical mould having 3 pts. Slots in the perimeter of a rotating drum form the half. Blocks linked together to form a chain form the upper half of the mould, each block contributing one quarter of the mould wall. The chain is in contact with the drum surface for a rotation of >=90 degrees of the drum about its axis. During this time a plunger mounted on the drum coaxially with the mould whose outer dia. corresponds to the inside of the mould is forced by a guide profile attached to the drum chassis into the mould. The lolly material is compressed to the shape of the lolly as defined by the head of the mould and the plunger head. At the same time another plunger mounted on the opposite side of the mould inserts the lolly-stick into the lolly. The two plungers are then returned and, as the chain leaves the drum, the finished lolly is easily removed from the drum either mechanically or by hand. The lolly material is fed in a continuous band onto the drum surface moving in the same direction as the drum. As the chain descends onto the drum surface the leading edge of the block cuts off a piece of the material and encloses it in the mould. The drum is driven by a motor. The continuous chain is driven by the engagement of the mould blocks with the plunger. The machine is quiet and, since all the parts move in the same direction and the mould closes gradually, there is minimal wear.
