Title: Improvements in or relating to apparatus for analysing gases
IPC: G01N7/04
Filed: 1931-10-01
Abstract: <PICT:0372221/III/1> In gas-analysis apparatus using a liquid absorbent, a sample of the gas is drawn into the barrel of a syringe 1, the nozzle 2 closed, and the syringe 1 placed in an upright position so that the barrel which is a sliding fit falls by its own weight over the plunger 4.  The level of the top plunger 4, or a meniscus of a liquid neutral to the gases to be treated, is measured on a scale 6.  Some suitable absorbing liquid is then drawn into the syringe 1 and, after absorption, the measuring operation is repeated, the difference in the readings being proportional to the amount of gas absorbed.  The instrument may be used in the reverse position, and the scale may also be marked upon the syringe 1 or the plunger 4. Register marks 14, 15 are provided so that the handle 5 may be inserted in a constant position in the metal shoe 13.

Abstract: 707,781. Conveyers. BASON & SONS, Ltd. Nov. 17, 1952 [Nov. 27, 1951], No. 27740/51. Class 78 (1) [Also in Group V] Bricks 6 are pushed endwise on their load bearing surfaces from a press 5 along a table 7 on to an endless belt conveyer 8. When the bricks reach an abutment (not shown), a pusher 14 reciprocated by a cam (24) operated bellcrank lever 21 pushes the bricks over the edge of the conveyer on to a conveyer 31 which carries them to a sanding machine. The drop from one conveyer to the other is such that each brick falls transversely of the conveyer and remains resting upon its side. The bricks may be controlled during their drop by a roller or other guide immediately below the edge of the conveyer. The speed of the conveyer 31 is such that each brick is carried clear before the next drops and preferably the parts of the apparatus are so timed that the bricks are deposited in a continuous row. The operative run of the conveyer 8 may be supported by guide plates. The pusher 14 is driven in timed relation with the press by driving the cam 24 from the main shaft of the press.

Abstract: 320,221. Hermann, F. G. Sept. 27, 1928. Thrashing-machines.-Dust-removing apparatus for thrashing-machines whereby dust is drawn out by suction from the machine, from behind the thrashing drum, from over the straw shakers, from behind the short straw outlet, &c., comprises a casing 2 mounted upon the thrashing box 1 and a suction tube 3 therefrom which leads to the short straw outlet or other part to be evacuated. A thrashing-drum is supported in front of a basket 6. A coarsely perforated plate or wide-meshed sieve frame 7 with suspended plates 8 and supported by a chain 10, is arranged behind the drum 5 to prevent corn therefrom being thrown backwards and yet permit the passage of dust laden air. The casing 2 comprises a box 11, with bottom circular apertures 13 over which rotate vane wheels driven by a pulley 15 and. bevel gearing. The wheels have sieves underneath, and foreign bodies collecting therein are thrown out by centrifugal force. Obliquely arranged underneath are wood strippers 20 with wire prongs which remove short stalks, &c. The suction tube 3 and a discharge to atmosphere are connected to the casing. The tube 3 ends in a device 4 which removes dust from the short straw chamber, and comprises a tube 22 rotated against a brush 28 which extends the breadth of the machine. The tube 22 consists of wire gauze or perforated or slotted sheet metal, with apertures. so fine as to permit only the exit of air. Flared tubes divide up the tube 22 to ensure uniform suction throughout its length. Guide plates may be arranged in the funnel-like expansions. Alternatively, a stationary tube 29 may be used in lieu of rotating the tube 22. Tube 29 carries nozzles or pipe unions 30 to which are secured by resilient means cylindrical sieves 32 which vibrate when 'the machine is working and prevent the settling of large particles. The sieve tubes and suction box may be applied to other parts of the machine.

Abstract: 949,037. Welding by fusion. BRITISH OXYGEN CO. Ltd. Aug. 11, 1960 [Aug. 14, 1959], No. 27944/59. Heading B3R. In a method of arc welding spaced in line butt joints in which relative movement between a welding head and the work is effected at welding speed during the welding operation and at the same or a faster speed between welding operations, and in which the relative movement is halted for predetermined periods at the beginning and end of each operation during which periods the arc is struck or extinguished, the periods occur when the welding head is over the work but spaced a short distance from the ends of the joint and weld metal is allowed to melt back or forward to the ends of the joint where it is supported until solidified. The movement may be controlled photo-electrically as described in Specification 935,586 or by a mechanically operated cam arrangement. In a machine for butt welding the projecting portions 107 of two castellated beam halves 105, 106 to form an I-beam, the joints are backed by a bar 113, e.g. copper, on which are positioned damming members 114 which may be recessed and which serve to retain granular flux 115 against the edges of the portions 107. When the welding head 100 dwells over the point X near the beginning of the joint the arc is struck using a high-frequency voltage and the weld melts back to the supporting flux 115. When the welding head 100 dwells over the point X near the end of the joint, feeding of the electrode is stopped and the electrode burns back before the welding current is interrupted. Meanwhile, the weld melts forward to the supporting flux 115. The flux 115 may be deposited before welding commences or where a submerged arc welding head is used, the flux is deposited from the flux nozzle 119 preceding the electrode.

[Also in Group XXIII] A work-holder for use with a surface-grinding machine or the like, comprises a base, a member rotatable in the base and means for clamping a workpiece to the member, such means and the workpiece being adjustable in more than one direction transverse to the axis of the member. The workpiece is held by a collet 45, Fig. 1, and centralized with the shaft 12 by slip-gauges between slides 20, 42 and faces 44. Shaft 12 is rotatably held and axially fixed in the base 10 by a lock-nut 14 abutting a shoulder 11 on the shaft 12, the shaft being provided with a set-screw 1 for locking against rotation. The centre of rotation of the workpiece can be varied by adjustment of the slides 20, 42, which can then be locked by screws 50, and the angle of rotation can be checked from the scales 33, 34, Fig. 2. Stops 30 lockable in slots 31 and a pin 32 in the flange 15 of the nut 14, may be used for restricting the rotation of the shaft 12. A punch 35 is finish ground by locating a face 37 parallel with the base of the work-holder and securing the punch in the collet. The face is ground and shaft 12 is moved through 180 degrees and the second face 37 is ground. The punch is then adjusted by moving slide 20 until centre C 1  is aligned with the shaft axes, and the shaft is rotated to allow the grinding wheel to finish radius R 1 . Radius R 2  is similarly finished with centre C 2  aligned with the shaft axis. A hexagonal workpiece may be produced or any required shape by indexing shaft 12 through the required angles.
