Abstract: 911,036. Pipe couplings. GRESSEL A.G., Edm. April 24, 1961 [April 22, 1960], No. 14729/61. Class 99(1). In a tube coupling, a clamping collar 1 adapted to be disposed about a tube 2 has an external diameter which is reduced in step form to provide an annular stop F adapted to be engaged by the bore 3e of a coupling sleeve 3 so as to limit the degree of axial movement of the sleeve over the collar and thereby limit the deformation of the bore portion of the collar caused by such movement; prior to deformation, the bore of the collar is cylindrical and serves to maintain a concentric relationship between the tube, the collar, and the sleeve prior to and during deformation of the collar. The stop face F and the free end of the collar portion 1a may be bevelled on the peripheral surfaces thereof, and the conical surface 3e of the sleeve may include a radial shoulder.

Abstract: 290,984. Soc. de Recherches et de Perfectionnements Industriels. May 19, 1927, [Convention date]. Electrically vibrated keyboard instruments.- Beams of light passing through a rotating slotted disc 8, Fig. 1, sweep over a photoelectric cell 5 (connected to an amplifier 6 and loud-speaker 7) after passing through screens 10 of which the transparency varies in the path of the beam, as shown in Fig. 2 or Fig. 3. The width of the cell 5 is such that, but for the screens 10, the illumination of the cell produced by the successive. slots 8 would be constant. A potassium or other cell having no electrical inertia is employed, the character of the notes produced depending on the character of the shading of the replaceable screens 10, and the pitch of the notes depending on the pitch and speed of the disc 8 combined with the pitch of the screens 10. The disc 8 has twelve concentric series of slots (one series for each semitone of an octave), and is driven at a speed corresponding to the lowest octave. The light beams may be controlled by mirrors 3 or prisms on the keys 4, the volume of sound depending on the amount of depression, of the keys which thus more or less completely illuminates the slots 8. According to the Specification as open to inspection under Sect. 91 (3) (a), the light may fall directly through a rotating slotted or variably transparent disc or cylinder on to the cell, being controlled by key-operated shutters; and a. tremolo may be provided. This subject-matter does not appear in the Specification as accepted.

Title: Process for the removal of carbon monoxide from olefine-containing gas mixtures
IPC: C10K1/10
Filed: 1957-05-15
Abstract: Carbon monoxide is removed from olefine containing gases by passage of the gas through a solution containing cuprous and cupric salts. Atmospheric pressure is preferred at temperatures of 60-100 DEG C., but higher pressures can be used.  Aqueous solutions containing 70-10% of the copper as cupric and 30-90% as cuprous are preferred; solutions containing smaller amounts of cuprous can be used at lower gas velocities.  A catalytic amount of a salt of a noble metal of Group VIII may be present in the solution, e.g. 0,2-0,5 gram (per 100 grams of copper) of palladium chloride p  or nitrite.  Chlorine ions are preferably present, while solutions in hydrochloric acid, ammonia or amines or hydroxyalkylamines can be used.  Gases containing small or large amounts of olefines can be treated.  In a typical example, a gas containing 92,4% by volume ethylene and 4,4% carbon monoxide is treated at 80 DEG C. counter-currently at the rate of 75 litres per hour with 400 c.c.s. per hour of a solution containing per litre 48 grams of copper as cuprous chloride and 72 grams of copper as cupric chloride, to which solution has been added 2 c.c. of a palladium chloride solution containing 10% of palladium.  The treated gas contained no detectable carbon monoxide.

Class 39(i) In an electric discharge appara tus, such as a fluorescent lamp having a filling of mercury vapour and having a reservoir 9 of liquid mercury to replenish the filling as it is used up during operation, the reservoir is confined by a partition 10 which is of a material impervious to liquid mercury and mercury vapour but may have one or more apertures impervious only to liquid mercury such as for the passage of current lead 8, and the partition is secured along its periphery to the envelope 1 during manufacture to allow mercury vapour but not liquid mercury to pass around the periphery during operation by heating the envelope locally in the vicinity of the partition and deforming it by external pressure, or letting it be self-deformed, against the periphery of the partition. The partition 10 is preferably a pile of mica discs and the envelope 1 of soft glass or hard glass known under the Registered Trade Mark " Pyrex '' so that a seal cannot form therebetween. In the arrangement shown the pile of mica discs 10 is compressed between two glass discs 4, 11 sealed to the glass coating 5 of the lead 8. The envelope has fillets 2 and 3 formed during the above mentioned heating operation which assist in preventing the passage of liquid mercury and in holding the partition 10 in place. The tube may or may not be operated in a vertical position and may for example be reversed end for end. In manufacture the lead 8 is coated with glass 5, the glass disc 11 sealed thereto, the mica discs 10 and glass disc 4 slipped over the coated lead and the disc 4 sealed to the coating 5 while keeping a suitable pressure on the mica discs, the assembly then being inserted in the envelope 1 and the coated lead sealed thereto at 7. The envelope is then heated to deform it against mica discs 10 as above described, the mercury 9 introduced through exhaust tube 6 which is then sealed off, and the device is pumped and filled with rare gas through a second exhaust tube at the other end of the device. The envelope may be sealed to the partition over a small part of its periphery, and may be of oval cross-section.
