Title: Improvements in or relating to the manufacture of fibres from plastic materials, such as glass, in the molten state
IPC: C03B37/06
Filed: 1949-11-04
Abstract: 665,802. Glass &c. fibres. ALGEMEENE KUNSTVEZEL MAATSCHAPPIJ N.V. Nov. 4, 1949 [Nov. 5, 1948], No. 28326/49. Class 56. Fibres are formed from plastic material such as glass, in the molten state, by causing streams of the molten material to flow into and be attenuated by a gaseous fluid under pressure in an expansion passage provided with at least one part in the form of a divergence of which the outlet forms the downflow end of the passage, the angle of divergence of the walls relative to the axis of the passage being less than 1 degree 30 minutes, and the ratio of the surface of the outlet and inlet of the divergence being less than 4. The crucible 1 lined with refractory material 2 and heated electrically has drawing orifices 3 at its lowest part and a cover 3 with an opening 5 through which glass &c. cullet or marbles is fed from pipe 6. The crucible is surrounded by a casing 8. The orifices 3 may be arranged in a circle and the expansion passage formed by a divergence 10 of circular section, as in Fig. 1, or arranged in straight rows and the expansion passage formed by a divergence of elongated rectangular section, as in Fig. 3. The gaseous fluid under pressure is introduced at 12 and expands in the divergence reducing the pressure at the neck 10a and assuming a high velocity which attenuates the filaments. The expansion passage may first converge and then diverge, and be of circular section, or, as in Fig. 6, of rectangular section at the upper end of the convergent and circular section at the lower end where it meets the divergence 10, see 16 in Figs. 5a, 6. The convergent preferably connects tangentially to the surface of the inlet of the divergence and to the face 11 of the casing 8. The crucible is heated through electrodes 17, 17a which have a fluid tight joint 21 with the casing. When the divergence is of elongated rectangular section the angle of divergence is preferably less than 1 degree and the ratio of the surfaces of the outlet and inlet less than 3. The space into which the divergence leads may be maintained at a pressure below atmospheric pressure.

Filed: 1956-11-09
Abstract: 854,084. Type-printing telegraphy. SMITHCORONA MARCHANT Inc. Nov. 9, 1956 [Nov. 16, 1955], No. 28451/59. Divided out of 854,083. Class 40(3). In a telegraph keyboard transmitter, depression of a key displaces horizontally five code bars 106-110 which operate through bell cranks to set up the mark-space code combination on five contacts (not shown). The depression also results in the movement to the right of a universal bar 111 which, when it is fully moved, disengages a block 132 from the top edge of a locking wedge 144 and allows it to move upwards under the action of spring 146 to engage in notches 128 or 129 in the lower edges of the code bars to lock the keyboard against further operation. The upward movement of wedge 144 also closes a contact S701 which initiates a cycle of operation in the transmitter circuit (see Specification 854,083) to cause, sequential transmission of the mark-space conditions set up on the code bar contacts. At the completion of the cycle of operation, a solenoid E701 is energized briefly to withdraw the locking wedge and free the keyboard for a subsequent operation. With this arrangement, if a key is held depressed, after each brief energization of the solenoid, the wedge would normally move upwards again fully and reclose contacts S701 and cause repetition of the transmission. In accordance with the invention, this is avoided by providing block 132 with a pivoted L-shaped member 135 which is biased anti-clockwise by a spring 139. When the universal bar is first moved, the locking wedge rises between block 132 and member 135, as shown in Fig. 4. Thereafter, when the wedge is withdrawn by energization of the solenoid E701, if the key is held depressed to keep the universal bar displaced to the right, the end 136 of member 135 is moved on to the top of the wedge, as shown in Fig. 5, under the action of spring 139. The wedge is thereby prevented from rising again to close contacts S701. The keyboard includes a space-bar mechanism, Fig. 1 and 2 (not shown), which operates on the underside of the code bars to displace them to set up the five contacts, and which operates a separate contact by-passing contact S701 so as to permit repeat transmission if space bar is held depressed.

Title: Improvements in or relating to fluid operated machine tools, such as grinding machines
IPC: B24B47/06
Filed: 1938-10-04
Abstract: 519,812. Grinding. CINCINNATI GRINDERS, Inc. Oct. 4, 1938, No. 28793. Convention date, October 4, 1937. [Class 60]. A machine tool such as a grinding-machine comprises valve controlled fluid-pressure mechanisms for clamping a work-piece, and for effecting relative approaching and withdrawal movements between the work-piece and a, grinding wheel, the movements being controlled by a manually-operated lever which operates the valves through a friction drive, to cause clamping of the work and rapid movement between work and wheel, the lever then causing feed up to a stop by means of a cam ; reverse movement of the lever causes withdrawal of the wheel and unclamping of the work. The machine comprises a bed 10 on which is adjustable a slide 12 carrying an angularly adjustable table 13 carrying a chuck for the work-piece 16, which is operated upon by a grinding-wheel mounted in a head 22 pivoted on the bed 10 at 21. The head 22 is moved about the pivot to move the wheel up to the work by means of a cylinder 24 in the head in which is a piston 26 on a plunger 25, this plunger resting on a second plunger 29, which, through a roller 30, engages a cam 31; fluid is supplied to and exhausted from the cylinder 24 by pipes 27, 28. The cam 31 is mounted on a shaft 32 oscillatable by a handle 33, thereby feeding' the wheel into the work, to an extent limited by a stop for limiting the size of the work ; a gauge or indicating device carried by a swinging bracket also may be provided. The fluid pressure operating means comprises a pump 41 supplying fluid from a reservoir through a line 42 to a valve casing 49 and, through a branch 44, to a valve casing 45. As shown in Fig. 3, the machine is in inoperative position, and fluid passes through the valve 54 in casing 49, a resistance 50, and a line 52, so as to move the valve 54 to pass the fluid to exhaust; the line 51 also is blocked. When the lever 33 is moved anti-clockwise, the valves 63, 81 are operated through a pin 78 engaging elongated notches 79, 80 in the valves and moved by an arm 72 frictionally held by clutch parts 73, 74 on the shaft 32 ; the first movement of the lever permits movement of the valve 63 by a tension spring 82 so as to admit fluid for example, compressed air, from a source 60 through a conduit 84 to move a piston 67 to clamp the work 16 on chuck members 70. Further movement of the lever 33 moves the valve 81 against a compression spring 83 thereby admitting fluid through the pipe 27 to the cylinder 24 to move the wheel up to the work, after which, continued movement of the lever causes no further movement of the valves, but brings the cam 31 into operation to feed the wheel into the work, the arm 72 slipping on the shaft 32. When the movement of the handle is reversed the valves are moved in reverse order, first to reverse the piston &c. 26 and then the piston 67. The gauging device is moved by a fluid motor 38 fed from the conduits to the work-holding device. U.S.A. Specification 2,025,885 is referred to.
