Abstract: 288,495. Arnold, C., (Oster Manufacturing Co.). Oct. 18, 1927. Stocks and dies; chasers.-In a screwcutting die-stock the chasers are mounted in radial housings on a plate which is rotatably adjustable on the body of the stock, the outer ends of the chasers having inclined surfaces which abut against axially arranged d pins secured to the body. In a. stock for cutting parallel threads, a turret body 1, Fig. 1, has pairs of aligned openings 4, 5, one of each pair receiving a work-guiding bush 6 and the other having mounted adjacent thereto a, plate 8 carrying housings 9 for the chasers 7. The plate is slotted to receive locking bolts 16 and permit rotary adjustment so that the chasers may be made to cut slightly over or under size through their inclined ends engaging pins 12 secured in bosses 13 on the body 1. Alternatively, a single die and bush may be provided on the body. In a stock for cutting taper threads, the body 20, Fig. 7, is provided with a lead-screw 23 engaging a sleeve 24 carrying jaws 25 adjusted by a scroll plate 26 to grip the work. The sleeve carries a rotatably mounted collar 33 to which are secured four pins 34 engaging the outer ends of the chasers 21 radially slidable in housings 39 on the plate 37. Radial adjustment is effected by rotating the plate 37 and the taper is produced by the chasers sliding along inclined surfaces 34a on the pins, the surfaces being rounded transversely to ensure line contact only with the chasers. The chasers are prevented from falling out of their housings by spring-pressed balls 43 in the body, and axial movement of the body is limited by flanges 36 on the pins. A bush 27 attached to the sleeve 24 protects the internal threads on the latter.

Title: Method of forming lens blanks
IPC: C03B23/22
Filed: 1960-08-10
Abstract: 893,651. Glass manufacture. PITTSBURGH PLATE GLASS CO. Aug. 10, 1960 [Aug. 17, 1959], No. 27682/60. Addition to 891,822. Class 56. A method of manufacturing a multifocal lens blank comprises placing a blank 10 of glass having a ground and polished countersink 12 formed therein below a previously sheared stream of glass issuing from an orifice O, causing the rate of flow across the cross-section of the orifice to vary in an asymmetrical pattern, directing the stream of glass on the supported blank 10 so that the initial shear mark 56 impinges upon the blank adjacent and outside an edge of the countersink 12, flowing the deposited glass across at least a portion of the countersink 12 to fuse thereto, providing relative radial movement between the blank 10 and the axis of the stream, while continuing the flow thereon, to assist the flow of glass across the countersink 12, stopping the relative movement and shearing the stream at 56<SP>1</SP>, so that the resulting gob of glass flows over and fills any remaining unfused surface of the countersink whereby the shear marks 56, 56<SP>1</SP> on the gob are positioned outside the countersink 12. The blanks 10 are mounted on support blocks 20 so that the countersink 12 is directed downwardly to one side of the block 20 and centrally of a groove 26 by which the block 20 is mounted on complementary lugs 24 on a conveyer 18 for passage through a tunnel lehr L to preheat the blanks, the blocks 20 being aligned against a stop 28. The heated blank 10 emerges from the lehr L under the orifice O of a melting tank MT, the orifice O being provided with a spreader tube 50 as disclosed in the parent Specification. The glass stream, which has been cut by shears 32 to leave a shear mark 56, descends to contact the countersink 12 as in Fig. 6 with the mark 56 outside the countersink. After a short period while the glass spreads across the blank 10, the block 20 is moved radially of the orifice O by a pusher device 36 from the dotted to the full line position of Fig. 8 and after a further short period of time the glass is sheared by the shears 32 to leave a mark 56<SP>1</SP> which is on the outer surface of the glass, both marks 56, 56<SP>1</SP> being removed in subsequent operations to form the lens. The pusher 36 then operates again to move the block 20 on to a transfer belt 34 from which it is pushed by a pusher device 38 on to the conveyer belt 40 of an annealing lehr A, the timing of the operations being controlled by a timer T. The blank 10 may be of glass with the following composition in percentages by weight: SiO 2  70.4; Na 2 O 8.4; K 2 O 7.7; CaO 11.9; Na 2 SO 4  0.4; Al 2 O 3  0.1; Sb 2 O 5  1.1 and the minor segment of the following composition: SiO 2  45.0; PbO 46.0; Na 2 O 2.1; K 2 O 6.4; Sb 2 O 5  0.5. The glass for the minor segment is rolled into flat sheets which are annealed before breaking to form cullet. The cullet is melted in a platinum-lined furnace and passes to a refining chamber at about 2550‹F. and then to a stirring chamber at about 2250‹F. Specification 749,169 also is referred to.

As described the casing is formed from a thin outer sleeve 6 extruded onto the wall of the borehole and a thicker inner tube 8 extruded onto the outer sleeve 6, both of which are formed by moulding apparatus carried by a body 10. A motor 1, e.g. a turbine or an electric motor, which drives a drill tool 2, is mounted at the lower end of the body 10 and the upper end of the body 10 is connected, via a control unit 9, to a flexible hose 3 inside which are fitted all the circuits required to supply the motor, to supply the oil circuits, for mud circulation and for supply of the moulding materials. The sleeve 6 and tube 8 are formed from thermosetting materials, a resin base and a hardener being supplied through separate circuits to a static mixer in the control unit for each of the sleeve 6 and tube 8. The supply of hardener can be cut off by a valve (not shown) and, when the mixer has been drained of hardener, supply of resin to the moulding apparatus can be cut off by a second valve. The sleeve 6 is formed of a material which will polymerise in water, e.g. a silicone elastomer resin, and is extruded from a zone 20, an inflatable sealing ring 22 preventing debris from the drilling from mixing with the resin. The resin is cured by heaters 18 in an inflatable mandrel 16. The tube 8 may be formed from an epoxy resin and is extruded from a zone 19. The resin is cured by heaters 17 in an inflatable mandrel 15, a cooling ring, 21 preventing polymerization of the resin in zone 19. The body 10 is moved downwardly stepwise as moulding and drilling progresses by an arrangement including a first inflatable sleeve 11 fixed to the body 10 and a second inflatable sleeve 12 fixed to a cylinder 42 which can slide over a piston 40 formed on the body 10. To lower the body 10 sleeve 11 is deflated, sleeve 12 is inflated and oil is supplied to the top half of cylinder 42 as shown in Fig. 3. At the end of the stroke sleeve 11 is inflated to hold the body 10, sleeve 12 is deflated and oil is supplied to the lower half of cylinder 42 to move the cylinder 42 together with sleeve 12 down the body 10. At the end of this stroke sleeve 12 is inflated, sleeve 11 is deflated and the cycle is repeated.

Title: Improvements in process for distilling carbonaceous material
IPC: C10B27/02
Filed: 1920-09-30
Abstract: 172,173. Wallace, G. W. Sept. 30, 1920. Coking processes. - In a process for distilling carbonaceous material by subjecting a continuous body of the material to heat in a closed chamber in such a manner that the material becomes coked progressively, the evolved gases and vapours are withdrawn through unobstructed passageways in the barrier of solidifying material in the coking- zone which is at a temperature of from 650‹ to 750‹ F. The apparatus comprises an externally heated retort A having a central gas-outlet duct C in which are screwed radially-disposed slotted ducts E projecting through the coking zone X and the thin barrier Y of solidifying material that separates the molten mass from the already formed coke Z, whereby the gases generated are withdrawn without disrupting the barrier Y. A flange 3 on the duct C supports the coke which is withdrawn upwards through the retort and the ducts E serve to hold the coked residue to the duct C while the mass is conveyed away. Specification 129,997 is referred to.

Title: Apparatus and processes for cooling heatable fused salt melts
IPC: F28C3/08
Filed: 1975-07-04
Abstract: 1487807 Agitating and circulating liquids CARL CANZLER 4 July 1975 [12 July 1974] 28168/75 Heading B1C [Also in Division F4] A hot salt melt in a vessel 1 is cooled by passing water through a heat exchange coil 14 where the water is at least partially evaporated to form steam or a fine mist. Thereafter, the at least partially evaporated water is passed through openings 4a, into contact with melt within a pipe 4 to agitate the melt. Any remaining water then evaporates. The melt rises through the pipe 4 to a separator vessel 5 from which steam passes through a duct 7 and melt passes through a pipe 6. Pipe 6 opens tangentially into the vessel 1 at 6a and, thereby causes returned cooled melt to circulate and mix with hotter melt in the vessel 1. The steam passes from duct 7 to a condenser 8 which is cooled by medium from a cooling tower 18. The condensate passes via duct 9, vessels 10, pump 11, duct 12 and regulating valve 13 to the heat exchanger 14. The salt melt may be used for heat treatment objects. The objects are immersed in the salt melt in vessel 1 and thereafter dipped in water in the vessels 10 to wash salt therefrom. This removed salt is thus recycled with the water to the vessel 1. When the objects being heat-treated are hotter than the heat treating temperature of the melt, the melt is cooled as indicated. When the objects are cooler than the melt, the melt can be heated by an induction heater 2. In modified apparatus, the heat exchange coil 14 is replaced by a duct (19), Fig. 2 (not shown). which coaxially surrounds the pipe 4. The cooling water is guided spirally downwardly through the annulus between the duct (19) and pipe 4. The melt may be at a temperature within the range 400-550C.
