Title: Improvements in or relating to a method of, and apparatus suitable for use in measuring any change in length of an optical path between a source of optical radiation and a primary image of the source
IPC: G01D5/30
Filed: 1967-09-21
Abstract: 1,207,174. Photo-electric measuring apparatus. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Sept. 21, 1967 [Sept.21, 1966; April 13, 1967], No.13632/70, Divided out of 1,207,173. Heading G1A. The measurement of any change in the length of an optical path between a light source 601 and an image thereof is carried out by the use of a rotating slotted disc 604 carrying on its front surface transparent members of known thickness 605, whereby the image is produced alternately in two positions, one in front of and the other behind the plane of the apertured disc and a photodetector detecting light passing therethrough. When the images are equally spaced in front of and behind the plane of the disc, equal intensities are received and any amplitude modulation superimposed on the chopper frequency in the detector output is thus indicative of a change in the optical path. The apparatus can be modified for detecting displacements of reflective surfaces, Figs.3, 4 (not shown) and used in the applications referred to in Specification 1, 207,173.

Title: Improvements in or relating to catalytic purifying processes for coke furnace gases
IPC: B01J23/96
Filed: 1965-03-31
Abstract: A process for reducing the C2H2 content of coke oven gas by hydrogenation over Pd catalysts, comprises passing the gas over two Pd catalysts in series, the first catalyst being the less active, each catalyst, between complete regenerations, being alternately subjected to at least one pseudo-regeneration, and at least one semi - regeneration.  The pseudo - regenaration comprises heating the catalyst to 175 DEG  to 225 DEG  C. for at least 48 hours, and the semi-regeneration comprises contacting the catalyst with superheated steam at 325 DEG  to 375 DEG  C. at a space velocity of 4500 to 5500 Nm3h. for at least 24 hours. Pseudo-regeneration may be carried out with the catalyst in use, but semi-regeneration requires the catalyst to be isolated. Suitable valved connections enable the gas to be led to the catalysts in the correct sequence.  Complete regeneration comprises treatment with steam, e.g. at 2 atmos., at 400 DEG  to 550 DEG  C. for at least 48 hours, the treatment continuing for a further 24 hours with an increasing proportion of air mixed with the steam, followed by cooling with air.  Five specific examples are described, which include the compositions of the gas to be purified.

Abstract: 1,014,942. Making radiators; metal working presses. AGA-PLATFORADLING A.B. April 8, 1963 [April 12, 1962], No. 13843/63. Headings B3A, B3H and B3R. A driving device for a plurality of working machines which together with a press form part of a continuous line for the manufacture of sheet-metal articles such as radiators and convectors comprises a separate hydraulic driving operated by a connection with a driving shaft of the press or with a device operating in synchronism therewith. The line comprises a press 7 for forming channels in strip material 5, 6 fed from reels 3, 4, an hydraulically actuated feeding device 8, welding machine 9 and cutting machine 10 which successively feed and spotweld the panel strips together and cut them from the strip. The hydraulic motors 23, 26, 29 of the machines are coupled to hydraulic cylinder assemblies 15, 17, 19, respectively, which are pivotally connected at their cylinder ends to a stand 14 and at their piston-rod ends 16, 18, 20 to a beam 13 pivotally mounted at 30 on the stand and which is vertically reciprocated by a connecting-rod 12 connected via an eccentric to the press driving shaft. The rod 16 is connected to the beam via an elongated slot 32 such that oil pressure fluctuations are only produced in the cylinder by the movement of the piston during the latter part of the beam stroke. The pressure produced actuates the motor 23 to effect rapid feeding of the strips whilst the press is open and resetting of the motor during the closing of the press. The rod 18 is selectively connected via holes 34 to the beam according to the length of stroke and hence the pressure required by the motor 26 to actuate the spot welder simultaneously with the closure of the press. The connecting-rod 12 is connected tc the beam by a pin 34a and the ends thereof extend into elongated slots 35 in the piston-rod 20 so that the reciprocating movement of the rod 12 is not transferred thereto. To effect operation of the cutting machine a pair of electromagnetically operated blocks 36 posi tioned adjacent to the slots are periodically triggered by a counter and moved therein tc effect a rigid coupling between the reciprocating rods 12 and the rod 20 and subsequent pres surizing of the motor system 29. The beam may be omitted and the press driving shaft con netted directly to the piston-rods of the machine driving cylinders. The cut-off radiator sections are subsequently circumferentially welded and inlet and outlet fittings connected thereto.

Abstract: 1,030,604. Welding by pressure. NEDERLANDSE ORGANISATIE VOOR TOEGEPAST - NATUURWETENSCHAPPELIJK ONDERZOEK TEN BEHOEVE VAN NIJVERHEID, HANDEL EN VERKEER. April 9, 1963 [April 10. 1962], No. 14150/63. Heading B3R. In explosive welding metal workpieces, intermediate metal or metals in powder, foil or coating form are provided between the pieces such that during welding ductile mixed crystals are formed with the intermediate metal or metals to provide a continuous ductile zone between the pieces. The quantity of intermediate metal or metals is such that after welding, the intermediate metal atoms are present only in the mixed crystals and so avoid inter-metallic compounds. A minimum thickness of 2 microns in the intermediate metal is necessary. The intermediate metal is applied as foil, powder mixed with binder or by electroplating or vapour deposition to the metal opposite that with which it forms the ductile crystals. In welding a sheet of 99.5% aluminium to a sheet of stainless steel containing 16À5-18À5% Cr, 10À5-12À5% Ni, 0À06% Co, 2-2À5% Mo and balance Fe, a layer of copper powder 20 microns thick is applied to the aluminium sheet and a sheet of pentrite explosive is ignited to pass a shock wave through a rubber buffer into the aluminium sheet, the steel sheet resting on a steel support. After welding a continuous ductile zone of mixed crystals of Ni, Fe, Cr and Cu is present between the steel and aluminium, with a lack of separate copper formation. Steel with a nickel content of less than 6% is provided with a nickel layer and the copper layer is provided on the aluminium. The two workpieces may be of the same metal and may be tubes. Parts of stainless steel comprising more than 6% Ni may be welded together using an intermediate copper layer. Manganese may replace the copper to provide mixed crystals of 50% Mn and 50% stainless steel when one of the parts is of another metal. Brass may be welded to austenitic stainless steel using a copper layer on the steel, niobium welded to aluminium using copper on the aluminium and nickel on the niobium and hard metal welded to steel using copper on the steel and nickel on the hard metal. Metal carbides may be similarly welded. Goldpalladium, silver-gold, silver-palladium, nickelgold and gold-platinum may be used as intermeniate metal

Abstract: 144,623. Pneumercator Co., (Assignees of Cornett, G., and Stancliffe, C. W.). June 7, 1919, [Convention date]. Indicators actuated by pressure of head of liquid.-In a gange of the manometer type having one limb open to the atmosphere an overflow chamber or trap is provided to prevent loss of the indicating liquid in the event of such liquid being expelled from said limb by the application of excessive pressure ; on normal pressure conditions being restored, the liquid flows back by gravity to the indicating tube. As shown in Fig. 2, the chamber 16 is put into communication with the upper end of the manometer tube 14 and is secured by a flange 19 and nipple 23 to a flange 20 on the indicating scale arm 21. The side walls of the chamber, which is sufficiently large to contain all the indicating liquid, are preferably convergent towards the bottom and one wall 24 is arranged in alinement with the bore of the tube 14. The top of the chamber is closed by a cover 17 provided with a vent 27, and a baffle 28 preferably integral with the cover 17 extends across the chamber for the purpose of deflecting the liquid away from the vent. The application of the apparatus for indicating the depth of liquid in a tank is shown in Fig. 1; the depth is measured by the air pressure, supplied by a pump 15, necessary to force the liquid down to the orifice 12 of a pipe 11 submerged in the liquid. The pipe 11 is connected to a chamber 18 which forms the other member of the manometer gauge. In the case of viscous fluids, excessive pressure may be required to expel the fluid from the pipe 11 and to prevent loss of pressure a branch pipe 29 provided with a cock 31 is connected at one end to the vent 27 and at the other to a point 30 on the pipe 11, said cock being constructed to permit the branch pipe 29 to be put into communication with the pipe 11 or the atmosphere. In the modification for the above-mentioned purpose, a loaded check valve is provided which is noimally open, but is adapted to close the vent on the application of excessive pressure.
