Abstract: 660,802. Making cupped articles. OLIN INDUSTRIES, Inc. Aug. 10, 1948 [Aug. 19, 1947], No. 21081/48. Classes 83 (ii) and 83 (iv). Cupping; extruding.-A method of making a closed end metal tube for example for making cartridge cases comprises preparing a tubular blank with a saw-toothed edge, as by cupping a polygonal blank, then extruding the blank by pressure applied against the saw-toothed edge and the opposite end of the annular side wall. A die comprising a cylindrical aperture 28 with a flared upper end 27 and containing in its lower half a member 24a with an inwardly extending flange 30 co-operates with a plunger comprising a tapered former or plug 33 below an outwardly extending flange 34 of a size to fit the aperture 28. In operation a polygonal blank 8 is placed centrally over the top of the die aperture 28 and the plunger is forced down. The tapered end 33 first pushes the blank into the upper part of the aperture 28 to form a cupped member with an upper saw-toothed edge 12, as shown in Fig. 2. On further downward movement of the plunger the blank is extruded through the annular opening between the plug 33 and the flange 30 to form an elongated cylindrical member 14. The scrap ring left between the sloping surfaces 29 and 35 of the flanges 30 and 34 is then severed by a trimming-punch 36, Fig. 6. In a modification, Fig. 8, a composite plunger is used, comprising a central arbor 43 with a tapered cupping former 45, and a concentric sleeve 44 with a flange 46 which forms the extrusion ram. If desired, the blank may first be cupped and then extruded in a separate operation.

Title: Multicomponent infra-red gas analyser
IPC: G01N21/37
Filed: 1949-08-13
Abstract: 683,952. Infra-red gas analysis. DISTILLERS CO., Ltd., and MUNDAY, C. W. Aug. 4, 1950 [Aug. 13, 1949], No. 21116/49. Class 20 (iii). A radiation absorbtion gas analyser is provided with a filter unit comprising at least two filter cells, any one of which may be rotated into position in the radiation beam. As shown, a single beam of radiation from a source 19 is reflected from a concave mirror 21 through a cell 22 containing the gas mixture to be analysed. The beam then passes through one of a number of filters 23 mounted in a rotatable holder 31. Each filter contains all but one of the constituents of the gas 21, this constituent being the one it is desired to determine. The beam is then split into two parts by a cylinder 25 with slots on its surface, the arrangement being such that the beams are blocked alternately. The two separate beams are then each directed to one of the two halves of a split cell 26 a number of such cells being mounted in a holder 32 mechanically coupled to the filter holder. A plan of the split cells is shown in Fig. 4. One half of each cell is filled with a standard gas such as oxygen and the other half with the component of the mixture being tested for. The two beams are received alternately after reflection from a concave mirror on the radiation detector 29. A screwadjusted balancing shutter may be mounted on each filter. In the arrangement according to Fig. 8 (not shown), a further slot is provided in the cylinder interrupting 25 which interrupts a reference radiation beam reaching a photocell to provide a reference voltage. This voltage is compared with the voltage difference produced at detector 29 by each of the two beams and a phase sensitive amplifier feeds a servo-motor which adjusts a shutter in one beam. The servo-motor also adjusts a recorder. In the arrangement according to Fig. 1, filed with the Provisional Specification, two radiation beams are each interrupted by a rotating shutter 3. Each beam passes through one of a pair of cells 5, 6, one of which contains the gas under analysis and the other a test gas. The filter holders 15, 16 are coupled together and may be rotated after an adequate period has been allowed to make a reading with each pair of filters in position. The filters again contain all but one of the constituents of the gas in chamber 5 while chambers 10 and 11 contain all the constituents of the gas under test. Unbalance of the two radiation beams due to absorption in chamber 5 of the substance to be detected results in uneven expansion of the gases in chambers 10 and 11. The pressure pulses are detected by a diaphragm condenser 12 adjoining the chambers and indicated on a meter 14.

Abstract: 981,038. Rolling. MORGAN CONSTRUCTION CO. May 30, 1963 [July 19, 1962], No. 21651/63. Heading B3M. A vertical rolling mill with overhead drive comprises a pair of rolls mounted in a laterally movable housing which is detachably connected to a vertically adjustable platform, the platform preventing horizontal movement of the housing parallel to the pass line but allowing transverse removal of the housing when the overhead drive is disconnected. As shown, vertical rolls 76 and 78 are mounted in a housing 38 and are driven from a motor 14 through a gear-box 2, telescopic spindles 16 and 18, and couplings 28 and 30. The housing is clamped to a platform 102 by pivoted tie bolts 104, and the platform is supported at its corners by fixed screws 116, rotation of worm-driven nuts 118 by a motor 132 causing vertical motion of the platform and housing. A trough 110, integral with the platform, directs cooling water and scale into an inclined conduit 114. For renewing or changing the rolls the drive couplings are first disconnected, a cable 50 being actuated, for this purpose, by a lever to lift a rod 54, attached to the cable and guided in sleeves 58 and 60 attached to a protective shield 36, and hence lift a frame 64. The shield 36, having first been uncoupled from the housing at 40, is raised at the same time. The drive spindles 16 and 18 are raised by rollers on the frame 64 co-operating with collars 70 and 72 on the spindles. The housing is thus lowered by motordriven worms 118 until the top of the housing is level with transverse rails 158, the housing is uncoupled by bolts 104 from the platform, and the housing is shifted laterally on to the rails by a piston 160. Lateral movement of the platform is prevented by Watt-linkages 136 while vertical movement is permitted. A vertically adjustable work guide 82 is mounted on bars 88.
