Abstract: 1,026,731. Continuous moulding. ROCMA ANSTALT. Aug. 23, 1963 [Sept. 10, 1962], No. 33469/63. Heading B5A. Apparatus for the continuous production of slab-like members of plastic material, e.g. thermoplastic foam, comprises a frame 1, 2, 3, two endless band means 5 defining a narrow vertical mould cavity, having for example a width of one decimeter, means for synchronously driving said band means and means for feeding mouldable composition into the inlet end of said cavity. The bands 5 may consist of an endless series of strip-like elements as shown or sheets of flexible material, gaps being provided between the interpivoted strip-like members and perforations in the flexible sheets, to allow the escape of excess pressure or material during moulding. The width of the mould may be varied by displacing one of the endless bands 5 relative to the other on the frame by manually operated screw mechanisms. Temperature control means may be provided by electric heating elements or by a fluid heating or cooling medium in the band elements or adjacent thereto. Removable separator wall elements may be inserted at desired intervals between the bands 5 to form slabs of a desired length. Concurrently with the introduction of the plastic material into the mould continuous sheets of a flexible material may be fed into the mould, adjacent to the bands 5, to supplement the action of a mould-stripping agent applied to the active surfaces of the bands. A horizontal bottom wall may be provided for the mould cavity by an endless belt or a strip of expendable material driven in synchronism with the vertical bands. The active surfaces of the mould may be cleaned during their return movement and the bands may have patterns or relief on their active surfaces to imprint patterns or corrugations on the moulded slabs. A cover having an exhaust conduit 11 is provided in order that gas and vapour generated during moulding may be drawn off. The invention may be applied to the continuous moulding of non-cellular plastic slabs or sheets, e.g. polyvinyl sheet, compressed wood-dust, plaster and concrete slabs and cake, biscuits and the like.

Title: Gasdynamic lasers
IPC: H01S3/223
Filed: 1973-07-16
Abstract: 1432400 Lasers OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 16 July 1973 [17 July 1972 16 March 1973] 33790/73 Heading H1C A CO or CO 2  gas dynamic laser comprises a chamber into which at least one pressurized gas, including nitrogen, is introduced and heated, and a convergent-divergent supersonic expansion nozzle connecting the chamber to a lasing region defined by resonator mirrors, an injector being located symmetrically in the throat of the nozzle which introduces at least one further gas flowing parallel to, and mixing with, the gas stream passing from the chamber to the lasing region. CO lasers.-A mixture of N 2  and CO at a temperature of 2500 K. or above is produced in a stainless steel, graphite-lined, and optionally cooled chamber 30, Fig. 1, by the reaction of inlet gases NO 2  and C 2 N 2  introduced through respective ducts 31, 32. Other suitable inlet gas combinations involve N 2 O with C, C 2 - (CN) 4 , CNN 3  or C 2 N 2 , or NO 2  with C, C 2 (CN) 4  or CNN 3 . The excited mixture of N 2  and CO passes from the chamber through a duct 33 and a convergent-divergent expansion nozzle 34 to a lasing region defined by spherical and planar resonator mirrors 28, 29, the planar mirror being partially transmissive. The nozzle is formed by copper blocks 50, Fig. 2, and its throat is provided with graphite insets 51. A copper injector 40 is positioned symmetrically within the nozzle throat for introducing a monoatomic gas additive such as He or Ar into the excited gas stream, the injector being formed with coolant and gas additive ducts 41, 42 of which the latter communicated with the downstream edge 54 of the injector through alternately offset injection holes 53, 53<SP>1</SP>. Injection of the monoatomic gas reduces the temperature of the combined gases by thermal conduction to the constraining walls, the combined gases being at ambient temperature in the lasing region and having a high vibrational level state due to nitrogen-carbon monoxide collisions within the chamber. CO 2  lasers.-Nitrogen is introduced under pressure in a water cooled chamber, Fig. 4, formed by coaxial copper tubes 11, 12 and end plates 13, 14. The nitrogen is excited to a temperature of between 2500 K. and 3000 K. by an electric discharge between the concentric tubes which form electrodes; and passes through a convergent-divergent nozzle 18 to a lasing region defined by resonator mirrors 28, 29. An injector, Fig. 5 (not shown), similar to that of Fig. 2, is used to introduce CO 2  and a monoatomic gas additive, such as He, into the excited nitrogen at the throat of the nozzle, the CO 2  gas attaining a high vibrational level state by collisions with the nitrogen. Water may be used as an optional additive in either embodiment.

Abstract: 764,202. Moulding-machines. AKTIEBOLAGET WESTIN & BACKLUND. Nov. 29, 1954 [Dec. 2, 1953], No. 34529/54. Class 83 (1). In a moulding-machine having a series of stations including a jolting-station, and wherein a pattern-plate is pushed forward by engagement with a succeeding pattern-plate in a series of such plates from the jolt-station to the next treatment-station, a movable dog co-operates with the pattern-plate 1 or a part associated therewith while it is being jolted, to maintain it spaced from the next succeeding pattern-plate 1a which has been jolted and is being treated in the next treatment-station, and after completion of the jolting, releases the first-mentioned pattern-plate to allow its transfer to the next treatment-station. The pattern-plates are supported on wear-strips 3, 9 on an extension 6a of the jolt-piston 10. A cylinder 19 is formed within the jolt-piston 10 and carries a plunger 20 having attached thereto a centring-pin 22 which passes through a guideway 23 which closes the upper end of the cylinder 19. The pin terminates in a conical portion 24 which, when the plunger 20 moves upwards, co-operates with a roller 25 secured to the pattern-plate, to thereby move said pattern-plate to the left, as shown in Fig. 1, to leave a gap between it and the pattern-plate la. The end 24 also enters a locating-recess 27 in the plate. The plunger 20 is raised when jolting commences, by pressureair entering the chamber 19, and is maintained raised until jolting is stopped, since the chamber 19 is in communication with the air inlet 13, through one of the passages 17, 17a, 17b as the jolt piston 10 reciprocates. When the air supply to the inlet 13 is cut off, the plunger 20 and pin 22 return to their bottom position under the action of a spring 28 so that the plate 1 may be moved to the next treatment-station by the following pattern-plate. The plate 1 may be spaced from the plate 1a by moving it to a different level.
