Title: Process for lining tube branches, consisting of welded tubes, with a protective internal coating
IPC: B05D7/22
Filed: 1930-11-29
Abstract: 355,148. Lining metal pipes. TRAUT, R., 69, Friedrichstrasse, M³lheim, Ruhr, Germany. Nov. 29, 1930, No. 35953. Convention date, Aug. 12. [Class 87 (ii).] Branched metal pipes, lined with a protective coating are made by almost wholly detaching the branch seat g from a plain pipe a, locating a confining ring d around the branch seat so as to have a margin round the curve of penetration, and placing a cover plate h over the partly detached branch seat. The main pipe a is then lined with protective coating in known manner, as by centrifugal action, after which the branch seat is removed and all lining cut away from the interior of the pipe as far as the ring d, which is also removed. The branch is then welded into the pipe preferably by an electrical welding process, damped pads being provided to prevent undue flow of heat along and around the pipe. A core o, Fig. 5, :is then inserted in the branch, to abut against a core m in the pipe and protective material is poured into the branch to line the branch and the bared margin around the branch seat. The curve of penetration around the branch seat may be completely cut through and the detached branch seat lightly welded back into position before the lining of the main pipe. Metal parts from which protective coating is to be removed are first brushed with milk of lime.

Abstract: 1,062,790. Testing container seals. EMHART CORPORATION. Aug. 24, 1965 [Aug. 25, 1964], No. 36264/65. Heading G1S. A testing apparatus for determining the capability of a container to be sealed at its open end comprises a sealing device engageable with the open end of the container 108 and with an interior surface of the container adjacent its open end to define a closed space 118 the volume of which is substantially less than the volume of the container, said sealing device having a conduit 98 for introducing fluid under pressure to said space, and a gauge 100 responding to pressure in said space to determine undesirable loss of pressure caused by leakage past said sealing device. In operation fluid under pressure is introduced into a chamber 4 above piston 20 (in position of Fig. 1 not shown) causing piston 20, and rods 22, 24, 54 to move downwardly until a coller 62 engages a shock pad 15. The gauge block assembly 32 continues to move downwardly compressing a toroidal seal 72 so that it forms a seal 116 against the inside of the container below the top edge thereof. The top edge of the container is engaged by a seal member 82, force being applied to the seal by a diaphragm 89. The closed space 118 is thus formed. Fluid under pressure is then introduced into the closed space through passage 96 and from a reading of the pressure therein, it can be ascertained whether the fluid is leaking past the seal 82. Fluid under pressure is then vented from above piston 20 and introduced below to return the rods and gauging block to their initial position.

Abstract: 368,791. Plucking poultry. BING- HAM, G. C., The Friary, Maldon, Essex. Dec. 11, 1930, No. 37448. [Class 28 (ii).] In a machine for plucking and stubbing birds of the type described in Specification 309,004, [Class 28 (ii), Kitchen and like appliances &c.], the deflection of the discs is effected by interposing projections 43 between the adjacent faces of the discs, the projections being arranged near the ends of a diameter, so that as the discs are engaged by guide members, e.g. rollers 49, the discs tilt on the projections and grip the feathers. The discs are carried loosely on a squared shaft 29 and the projections 43 are arranged at a different angular position on each disc. The projections are in the form of knobs and are arranged on one side of the disc and bear against wear strips 42 secured to the opposing face of the adjacent disc. Leather, rubber or like pads 44 may be secured on the gripping-zones of the discs. The rollers 49 are journalled in casings pivoted at 47 to the main casing and are adjustably pressed against the end discs by springs 51. The discs are driven by a motor connected by a belt to a pulley 22 on a shaft 23 carrying a fan 39 which sucks the feathers from the plucking-discs and delivers them to a bag (not shown) which is kept distended by a member 41. Two sets of plucking-discs, which may or may not have the features described above, may be arranged in one machine, one set being of large diameter to remove the feathers and the other being of small diameter to remove the stubs. The bird is placed against an aperture in the casing containing the plucking-discs and, in the case of the feather-plucking discs, the lower edge of the aperture acts as a plucking-bar, whilst in the case of the stub-plucking discs, the upper edge of the aperture serves for this purpose, the stub-disc moving upwardly at the gripping position. The discs may be sector-shaped instead of circular and they may be mounted on gymbals. Two sets of discs may be provided at one plucking position, the sets travelling in the same or opposite directions, or one set of discs reversible in direction may be used.
