Title: Improvements in or relating to lathes
Inventor: ARMAND MAURICE
IPC: B23B5/38
Filed: 1955-12-10
Abstract: 800,921. Lathe details. SPEEDY & EYNON (1951), Ltd. Dec. 5, 1956 [Dec. 10, 1955], No. 35542/55. Class 83 (3). A lathe or lathe-attachment for taper-turning comprises means attachable to the saddle 4 for driving the feed-screw (not shown), of the crossslide 5 from a pinion 12 engaging the rack 9 provided on the lathe-bed for traversing the saddle, the cross-slide thus being fed by the rotating pinion as the saddle is traversed along the rack. The saddle may be traversed by a hand wheel 10 or by a feed-shaft 7 driving the pinion 12 or another pinion. The pinion-shaft 15 is splined to a sliding-gear 17 in the casing 11 of the attachment, the gear being moved into engagement with a gear 22, for taper-turning, by a fork 19 on a shaft 20 provided at one end with an operating-handle 21 and at the other with a lever 28 interlocking with a controllever 8 to prevent the latter from engaging the direct feed from the feed-shaft to the cross-slide while the gears 17, 22 are in mesh. A shaft 23, supporting the gear 22 and a hand wheel 24, drives the cross-slide feed-screw, or a shaft connected to the screw, through a gear 25 in mesh with a gear on the screw or shaft. Changegear-wheels may be included to vary the angle of taper. The Provisional Specification refers also to the use of intermediate gears between the gears 17, 22 and a tumbler-gear if both internal and external tapers are to be turned.

Title: Process for the manufacture of sheet glass
IPC: C03B5/26
Filed: 1965-08-19
Abstract: In the manufacture of sheet glass by flowing molten glass 1 on to the surface of a molten metal bath 5 the thickness of the glass is controlled by a vertically movable damper 4 projecting below the level of glass on the upstream side of the damper and the damper or that part adjacent the glass is made of porous <PICT:1112969/C1/1> <PICT:1112969/C1/2> graphite or other refractory through which gas flows to prevent surface to surface contact between the glass and the damper.  The gas may be combustible and burn at the glass surface, thus providing a fire polish.  The gas may be preheated.  To prevent erosion of a graphite damper an enclosure around the damper may be provided and supplied with inert gas.  The lower surface at least of the damper is preferably of arcuate form and the damper may be a roller.  Passages for the insulation of cooling water may be provided in the damper.  The formed sheet of glass 9 may be progressively cooled at 12, 13, 14 while in contact with metal or may be air-cooled by upwardly directed air jets from a perforated bed 15 (Fig. 8), the air jets also supporting the glass sheet as it moves to the conveyer 11. The regulator 6 controlling the flow of molten glass from the furnace 2 may also be of porous refractory, as described in Specification 1,112,607.

Title: Improvements in or relating to microwave devices
Inventor: CLOUSER PAUL LEE
IPC: H03B9/14
Filed: 1968-07-26
Abstract: 1,242,228. Oscillators. WESTERN ELECTRIC CO. Inc. 26 July, 1968 [27 July, 1967], No. 35713/68. Heading H3T. An oscillator has a negative resistance active element (a tunnel diode 11) disposed in energy transferring relationship to a waveguide 10, a shunt inductive element 12 being arranged close to the diode 11 to suppress oscillations below the cut-off frequency of the wavepath, thereby ensuring that oscillation at a frequency not less than the cut-off frequency is produced at the output. The spacing 11-12 is preferably a quarter of a wavelength and transverse to the direction of propagation. The waveguide 10 is tapered to match its impedance to that of the diode, to which a phase-locking input is connected by an isolator 15. The inductive element 12 is adjustable in position by a portion 13 thereof which extends through a slit 14 in the wall of the waveguide. In a second embodiment (Fig. 3, not shown) the tunnel diode (31) is arranged in an inductive iris formed by two elements (32), the frequency being adjusted by a piston (37). The microwave power is supplied by way of a circulator (38). The tunnel diode in both embodiments could be replaced by a Gunn effect or L.S.A. device. The effect of the inductive element 12(32) is explained in terms of the frequency dependent capacitive impedance curve of the diode (1, Fig. 2A, not shown) which is crossed, in the absence of the element 12, by the circuit inductive impedance curves at two points (A,B) respectively above and blow the cut-off frequency, oscillation tending to occur at the lower frequency (A). In the presence of the inductive element 12 the circuit inductive impedance curves are modified (Fig. 2B, not shown) so that a cross-over occurs only at a frequency above the cut-off frequency; and oscillation therefore occurs at this frequency (C).

Column stills and rectifiers; evaporators, and condensers in structural combination.-Apparatus for distilling liquids which can be evaporated under high vacuum without spitting or formation of bubbles, e.g. oils, paraffin-wax, " Vaseline," &c. comprises a chamber adapted to be highly evacuated having a tray or trays therein heated by a heat vehicle which does not come into communication with the space within the chamber, and a condensing surface arranged above each tray in close proximity thereto so that substantially the whole of the vapour leaving the surface of the liquid impinges directly thereon. The condensing surface is so arranged that the con. densate clings thereon and does not return to the liquid and is maintained at the required temperature by a cooling fluid which does not come into communication with the space within the chamber. This apparatus is the same as that described with reference to Fig. 3 of Specification 303,078.

[Class 100 (iii)] Clamping matrices-The clamping face of a vice-jaw is wiped by a wiper mounted on the jaw and actuated by a periodically operated organ of the machine, such as the first elevator. The wiper comprises an arm 3 pivoted in a recess in the jaw 1 and normally pulled upwardly against a stop by a spring 5. The free end of the arm carries a roller 6 and a pivoted member 7, one end of which constitutes the wiper, and the other end of which is acted on by a spring plunger 8 to press the member 7 against the face of the jaw. The first elevator, in its descent, strikes the roller 6 and moves the arm 3 down. When the elevator ascends, the spring 5 raises the arm, and the jaw is wiped by the member 7. When the jaws 1, 10 close, for example, when blank slugs are being cast, a projection 13 on the right-hand jaw 10 strikes an extension 12 of the arm 3, and moves the wiper away from the jaw 1.
