Abstract: 1375065 Draughting machines KEUFFEL & ESSER CO 6 March 1972 [9 March 1971] 10403/72 Heading G1X A draughting device comprises a flat, magnetically attractable board 20 on which a magnetized cylindrical roller 11 is supported, the roller slideably supporting a yoke member 14 to which is attached a drawing element 16. The roller 11, which may comprise a tube or rod 12 to which is attached, by adhesive or by a nut and bolt arrangement, a plurality of axially aligned magnetized discs 13, Fig. 3 (not shown), spaced from one another by soft iron discs 35, is arranged on the board 20 parallel to an up-turned lip 21 defining one edge of the board so that the roller 11 is able to move relative to the board 20 only by rolling in a direction perpendicular to the lip 21. This movement together with the sliding engagement of the yoke member 14 on the roller 11 provides two perpendicular directions of movement of the drawing element 16 over the board 20. The drawing element 16 may comprise a triangular member provided with graduations along one edge and along a slot 17 and also with a rotatably mounted protractor 18 in a cut-out of the triangular member. The yoke member 14 which surrounds a major portion of the circumference of the roller 11 may be provided with bearing surfaces (26. 26<SP>1</SP>) Fig. 2 (not shown), matching the curvature of the roller 11 and coated with a solid lubricant such as P.T.F.E.

Abstract: 376,312. Carburetting apparatus for internal-combustion engines. SALE, B., Hall Green, Tean, Stoke-on-Trent. April 8, 1931, No. 10405. [Class 7 (iii).]. An automatic apparatus for minimizing and extinguishing fires in vehicles using internalcombustion engines, comprises in combination means for cutting off the fuel supply and the ignition, means for withdrawing the fuel already in the induction system, and means for releasing extinguishing materials for spraying the engine. As shown, cylinders M, L are provided, a vacuum being maintained in the cylinder M, and cylinder L being charged with extinguishing liquid. A rotary cock Y is held by a wire G against the action of a spring K, so that passages B, C in it connect the fuel pipe A with the induction system D, E. The wire G is retained by a fusible plug F. When the latter melts, the cock rotates, moving the passage B away from pipe A and bringing passages Q, C into communication with the cylinder M. Fuel already in the induction system is thereupon sucked into the cylinder M. Simultaneously, a passage P in the cock connects the cylinder L to spray pipes R, S, and the operating arm H of the cock closes a switch J to cut out the ignition. The wire G may also be released, in the event of an accident to the vehicle, by a slide W<1> operated by a lever X arranged in an exposed position on the vehicle.

Abstract: 1292224 Extruding P.T.F.E. FARBWERKE HOECHST AG 4 March 1970 [5 March 1969] 10419/70 Heading B5A [Also in Division H5] An electrical heating conductor comprises a conductive core 9 of a mixture of graphite, and/ or soot with polytetrafluoroethylene (P.T.F.E.), the weight ratio of graphite and/or soot to P.T.F.E. being from 0À1 : 1 to 2 : 1, and an insulating covering 10 of P.T.F.E. The heater is preformed in a mould, Figs. 1, 2 (not shown), and then extruded through a die 8 having, for example, a circular orifice. The core and covering may include a lubricant, such as white spirit, which is removed by heating, after extrusion, in a continuous heating furnace. The extrudate is then sintered and solidified. Alternatively, a rod-shaped extrudate made without the covering 10 is wound with a non-sintered P.T.F.E. tape and then sintered, or is provided with an extruded covering separately. The heating conductors are of circular or rectangular cross-section, Figs. 4, 5 (not shown).

Title: Turret lathes
IPC: B23Q16/06
Filed: 1928-04-05
Abstract: 288,339. Potter & Johnston Machine Co., (Assignees of Curtis, M. S.). April 7, 1927, [Convention date]. Turning.-In a lathe having a turret mounted on a slide, the slide is reciprocated by a rotating member which also actuates the turret indexing mechanism through constantly engaged gear connection. The turret 10 is rotatable on a central pillar 12 on the slide 11 and is clamped to the latter by a nut 15 at the lower end of the pillar. The slide is reciprocated by a cam-drum (not shown) carrying a gear wheel engaging an elongated pinion 18, Fig. 5, rotatably mounted on the lathe bed and meshing with a gear wheel 20 splined on a shaft 21, the gear wheel 20 being moved with the slide by arms 22 thereon. A bevel pinion 23 on the shaft 21 drives a bevel gear 24 rotatably mounted on the slide and carrying a roller 26 which engages radial slots 27 in a disc 28 attached to the turret and thus constitutes a Geneva mechanism for rotating the turret. An index bolt 34 is withdrawn from one of the recesses 35 in the disc 28, prior to the engagement of the roller 26 in one of the slots 27, by a cam 31 on the gear 24 acting on a roller 32 attached to a lever 33 connected to the bolt and simultaneously a cam 36 on the gear 24 rotates a lever 37 to unscrew the nut 15. After the turret has been rotated the bolt 34 is returned to one of the recesses 35 by a spring (not shown) and a cam 38 on the gear 24 acts on a lever 39 to rotate the nut 15 and clamp the turret. Reference has been directed by the Comptroller to Specifications 10638/98, 8136/99, 27226/10, 14596/11, and 125,909.

Insertion of the earth pin moves the slide against a spring 29 and disengages projection 26 from the shutter which is then free to be actuated by the live pins. The shutter may be of the kind described in Specification 605,500.
Patent GB-1219711-A (GB)
Title: Ink drop printing systems
IPC: B41J2/075
Filed: 1969-02-27
Abstract: 1,219,711. Printing. A. B. DICK CO. 27 Feb., 1969 [28 Feb., 1968], No. 10511/69. Heading B6F.  In a printing system wherein ink drops in a stream are variably charged in dependence upon electrical video-representative signals and are subsequently deflected in an electric field by an amount depending on the charge on each drop and then caused to impinge on a printing medium, means are provided whereby each drop charged by a signal is preceded and followed by one or more drops to which no charge is applied. To this end a known ink-drop printing system, Fig. 1 (not shown), is provided with gate means in the connections between the source of video signals and a nozzle and charging tunnel producing and charging the drops, the gate being connected to a frequency divider connected to a source of synchronizing signals. If the frequency divider is a bi-stable circuit, the gate allows a video signal to pass upon the occurrence of every other drop, the intermediate drops not being charged. A frequency divider which divides by three produces two uncharged drops between two charged drops. The effects of repulsion between adjacent charged drops are thus avoided. The uncharged drops are caught by a trough (38, Fig. 1).

The mixture of lubricating substance may be dissolved in a fairly volatile organic solvent such as a petroleum distillate having a boiling range of 150‹ to 170‹ C. The filaments may be contacted with the aqueous bath and the non-aqueous bath by passing them over two rotating carborundum rollers dipping respectively into the two baths. The stretch ratio used in the stretching step may be about 5À5 and the stretching may be effected using a snubbing pin maintained at 160‹ C.

Abstract: 611,250. Resistance coatings and deposits. JOHNSON, MATTHEY, & CO., Ltd., and WYETH, E. J. April 9, 1946, No. 10877. [Class 37] A resistor comprises an insulating tube having on its inner surface a metal layer formed partly or wholly as a continuous spiral. In a preferred method of manufacturing such a resistor, the tube 1 is of glass or porcelain and the layer is formed by applying a solution of a sulphurresinate or resinate of a precious metal, such as gold, silver or platinum in essential oils, and subsequently firing at such a temperature that the organic matter is burned away and the previous metal is left firmly adhering to the inner surface of the tube 1, Fig. 1 (not shown). A spiral groove 3 is then cut in the metal layer either by securing the tube 1 and rotating a pointed tool around the coated surface or rotating the tube and maintaining the cutting tool stationary. The pitch of the resistance spiral 4 thus formed throughout the length of the tube 1, Fig. 2 (not shown), may be varied according to the resistance value required. The tube 1 may be of glazed porcelain or glazed earthenware and the metal layer a precious metal alloy.
