IPC: C14B1/02
Filed: 1930-04-16
Abstract: 352,565. Pelt-shearing machines. VEREINIGTE HUTSTOFFWERKE BLOCH & HIRSCH C. F. DONNER GES., Niederrad, Frankfort-on-Main, Germany. April 16, 1930, No. 12078. Convention date, April 16, 1929. [Class 76.] A machine for removing hair from pelts by means of a rotary cutter co-operating with a ledger blade and arranged so that as the hair is cut from the skin the latter is cut into strips, is provided with means for producing a blast of air at the cutting point directed oppositely to the movement of the rotary cutter blade, a conveyer belt to which the cut hair is caused to adhere by suction, and a device for removing the hair from the conveyer belt in a reversed position. The cutter comprises an inner drum to which are secured helically curved cutter blades 8, and an outer cover 9 through slots in which the blades project. The cutter is supported by end bearings and rotates around an inner tube having a longitudinal slot a extending the width of the cutter and supplied with compressed air through a pipe 11. The inner drum is provided with slots b, c which are curved in the axial direction in parallelism with the blades and so arranged as to provide alternate tangential and radial blasts of air as they come into alignment with the slot a. The ledger blade 12 is supported by slide members adjustably mounted in the machine frame. The pelts are fed between rolls 19, 31, the roll 31 being carried by counterbalanced arms 32. The pelts pass from these rolls between a roll 20 and a guide roll 37 retractable by movement of the arms 32 and serving to support the conveyer belt 36. The pelts pass to the cutter through a slot between the blade 12 and a plate 62. The belt 36 is of material permeable by air and surrounds a tank 61 connected to a suction tube 45 and open at the upper end adjacent to the cutting point so that the sliver cut off and carried away from the cutter by the air blast is attached to the belt by suction and carried downwards on its upper surface. A receptacle 47 covered by a perforated plate 48 and connected to the interior of the tank 61 is pivotally mounted below the belt and is periodically turned to overlie the sliver resting on the belt and remove it therefrom by suction. Casings 58, 59 are provided around the cutter to receive the strips of skin cut off from the pelt.

Abstract: 1,256,271. Modified PVC. GAYLORD ASSOCIATES Inc. 7 March, 1969 [11 March 1968], No. 12275/69. Headings C3G and C3P. Polyvinyl chloride is grafted with butadiene or modified with polybutadiene such that the polybutadiene has a cis-1,4 content of at least 35%. The graft polymer is formed by reacting the PVC with butadiene in the presence of a dialkyl aluminium halide (which may be formed in situ) and a cobalt compound, preferably with the PVC suspended in an inert diluent e.g. chlorobenzene. The reaction of PVC with polybutadiene is effected similarly but the use of the cobalt compound is optional. Up to 10% based on the PVC of butadiene or polybutadiene is used and the product is a mixture of PVC and modified PVC which is more thermally stable than the PVC.

Abstract: 1500964 Welding pipes BOC Ltd 27 March 1975 [11 April 1974 13 March 1975] 12865/75 Heading B3R  Welding apparatus for forming continuously welded pipe-line from successive lengths of pipe by butt welding the lengths of pipe end-toend comprises a platform 12 displaceably mounted longitudinally on rails 14 in a sea going or land transporter means, the platform carrying a clamping device 22 for supporting and securing the end of the pipe-line 8 with respect to the platform and which also carries a pipe length mounting device 20 adjacent the welding station and a head stock 18 movable relative to the platform 12 and which carries a centering device 40 for the pipe length and which through the action of the head stock by way of the hydraulic jacks 34, urges the pipe length into abutment with the fixed pipe-line. A laser 16 mounted on the platform 12 cants a beam coaxial or parallel to the axis of the pipe-line and by way of suitably mounted reflecting surfaces 44, 42, 52, and 60 the beam is arranged to impinge on the abutting ends of the pipe, either radially inwardly or outwardly so as to weld the pipe length to the pipe-line by fusion from either inside or outside, or with the aid of a further laser simultaneously from both inside and outside. Various means are described for ensuring the alignment and abutment between the pipe and pipe-line. In Fig. 3 there is shown an internal coupling means 64 which may be in the form of a pneumatic bag holding the two portions in coaxial alignment. In Fig. 5 (not shown) an external clamping ring (92) is used. Figs. 8 and 10 (not shown) relate to internal and external radially located fluid pressure members respectively in separate devices one in each pipe portion. The latter devices may also be used for correcting deformity of the pipe ends to ensure a substantially circular joint. The laser used in the welding operation is of the gas shielded, carbon dioxide laser medium type using the infra-red portion of the spectrum. In order to permit visual alignment, the laser or any laser of the apparatus is supplemented by an auxiliary laser which produces radiation in the visible spectrum and projects its beam along the beam of the carbon dioxide laser. In addition to the use of the laser internal welding of the pipe sections the external welds could be carried out by MIG or TIG welding processes or by unshielded (open) arc. The apparatus may additionally include means 24 for crack detecting in the finished weld and further means 26 may be provided for coating the finished welded pipe as it is layed subsequent to the welding of the respective pipes. In the embodiment shown in Fig. 12 the laser beam 48 is directed in a plane transverse to the axis of the pipe-line and offset from said axis and the beam is subsequently directed on to the pipe joint region by a series of mirrors one associated with each of four slideways 120 located in said plane and surrounding the pipe, the mirrors being displaceable and pivotable to direct the beam in four successive stages on to the pipe joint to form the weld.
