Title: Improvements in or relating to reamers and screw taps
IPC: B23D77/04
Filed: 1952-10-23
Abstract: 712,083. Reamers; taps. OFFICINE MECCANICHE MAGAR SOC. R.L. Oct. 23, 1952 [Nov. 6, 1951; Feb. 22, 1952; Sept. 3, 1952], No. 26583/52. Class 83 (3). [Also in Group XXIII] A cutting tool, such as a reamer or tap for machining internal cylindrical surfaces, has a blade 9 with right-angled cutting edges 3, 4 and contacts the work by these edges and by a point 5 which is diametrically opposite the mid point of the line joining the edges, one edge cutting while the other acts as a guide, according to the direction of rotation of the tool. The blade may be integral with the body 1 or attached to it by radial screws as shown in Fig. 2 or by side screws or by wedges, adjustment of the cutting diameter being made by shims or by radial screws engaging the bottom of the blade. For reaming blind holes, the blade may extend to the end of the body. Fig. 10 shows a reamer in which the blade 9 is adjustable by a wedge 27 axially adjustable by screwed engagement with a graduated knob 24 ; after adjustment, the knob can be locked, by a screw 25 or screwed ring, to a boss 22 having handles 23. The blade may be held against the inclined plane 28 of the wedge by ring springs 60 or by leaf springs attached to the body and bearing on the ends of the blade. Since the radial adjustment of the blade displaces the centre of rotation of the tool by half the amount of adjustment, compensation for this in reamers intended for machine use may be obtained as shown in Fig. 12, where the wedge, adjusted by a screw 33, has a second inclined surface 28<SP>1</SP> of half the slope of the other surface 28, the surface 28<SP>1</SP> adjusting a rectangular shank 32 in a slot 31 in a sleeve 30 ; springs 35 urge the shank against the inclined surface and a pin-and-slot connection 37, 39 prevents axial displacement of the shank and sleeve. In a modification, the shank 50, Fig. 17, corresponding to the shank 32, is attached to a reamer, similar to that of Fig. 10, by arms 50<SP>1</SP> having surfaces slidably engaging . flats 51" on the reamer sleeve and adjustable on the flats by screws 56 on a ring 50" attached to the arms. In a non-rotating reamer for machining rotating work, the reamer is held in a bracket 40, Fig. 14, and the wedge 27 is adjustable by a lever 41 linked to it by a rod 43, the amount of adjustment being limited by a screw 44. The blades may be tapered to facilitate entry into the work or formed to ream conical or other shapes of hole and may be helically arranged. More than one blade may be arranged along the same axis or the cutting edge of a single blade may be interrupted along its length. For increasing the diameter of the reamer, a curved backing plate of hard metal can be attached in the region of the point 5. As applied to a finishing or tapered tap, a blade 69 arranged axially or helically may be secured by side screws 14, Fig. 24, or may be adjustable by a wedge 27, Fig. 26.

Abstract: 808,906. Treating waste waters. JONAS, V. Sept. 23, 1955 [Sept. 24, 1954], No. 27194/55. Class III. Industrial and town waste waters freed from matter harmful to a fermentation process are passed through a measuring apparatus 30, Fig. 1, to a continuously-operating fermentation device 1 to which are supplied air at 2 and, automatically according to the quantity of waste water, a fermentation agent at 18 and moulds, nutrition agents or the like at 19. The waste water is pumped at 4 to a clarifier 5 to which a clarifying agent, e.g. milk of lime, is supplied at 8 from a storage container 7. The clarified water overflows into a saturator 9 in which excess clarifying agent and other substances are precipitated by, e.g., carbon dioxide supplied at 10. The water rises from the saturator 9 to a discharge vessel 11 whence it flows to a sedimentation apparatus or filter 12. Clear treated water flows into a container 14 while sludge flows to a thickener 15, dryer 16 and container 17. Sludge free from precipitating agents may be obtained by inserting between the fermentation device 1 and the clarifier 5 a rotating suction filter 20, Fig. 2, from which the filtrate, collected at 21 by a vacuum pump 22, is pumped at 4 to the clarifier 5. Sludge including precipitating agents may be obtained by inserting the filter before the saturator 9. Instead of the filter 20 a flotation vessel 25, Fig. 3, to which air is supplied at 24 and from which sludge is withdrawn at 26, may be used. As a further alternative to either of the above a settling tank may be used either before the clarifier 5, Fig. 4 (not shown) or before the saturator 9, Fig. 8 (not shown). Sludge from the device 12 and water from the saturator 9 may be re-cycled to the clarifier 5. Water from the fermentation device 1 may be re-cycled to itself. Sludge from the flotation vessel 25 of Fig. 3 may be recycled to the fermentation device. Specifications 662,750 and 808,905 [Group VI] are referred to.

Abstract: 1,126,560. Laminates. SOC. RHODIACETA. 17 June, 1966 [18 June, 1965], No. 27271/66. Heading B5N. A fabric comprises a non-woven sheet 2 of continuous oriented synthetic organic filaments arranged at random in a non-parallel fashion across the sheet, and a non-woven sheet 1 of discontinuous staple fibres secured together by needle punching, the sheet 1 being secured to one face only of the sheet 2. The sheet 2 may comprise filaments of polyethylene terephthalate, isotactic polypropylene, polyamides, polyvinyl chloride, cellulose acetate, or polyvinyl alcohol, and the sheet 1 may be produced from staple fibres based on polyamides, polyesters, polyvinyl chloride or polyolefines, which are preferably crimped. The sheet 1 may be produced by carding, garnetting, or by pneumatic apparatus, and may be continuously deposited on the sheet 2. In one embodiment polyethylene terephthalate granules are fused in a single screw extruder and the fused mass is forced through a heated spinnaret to form filaments. The bundle of filaments is collected in a suction drawing tube spaced from the spinnaret so that filaments are oriented and air cooled and the filaments are then fed on to a moving endless belt in a random non-parallel manner by an oscillating deflector. The sheet so formed is calendered between heated rolls and constitutes the sheet 2. Two elementary webs produced on pneumatic apparatus from polyhexamethylene adipamide fibres dyed black are needle punched together to form the sheet 1 and this is then placed on the already formed sheet 2. The sheets 1, 2 are connected by further needle punching. The exposed face of the sheet 2 is then coated with an aqueous dispersion of polyvinyl acetate emulsion and dried in an oven. In other examples the coating which may be spread or sprayed on is of rubber, polyvinyl chloride, or polyvinyl acetate. The fabric produced may have a backing of polyamide 6/6 fibres glued to the sheet 2. The fabric produced is rot, damp, and mechanically resistant and may be used for floor covering.
