Patent GB-437755-A (GB)
Title: Process for providing tubes with an internal protective covering
IPC: B05D1/00
Filed: 1934-05-08
Abstract: Cylindrical tubes are lined by causing a hot liquid coating material to flow within the tube by slow rotation thereof, resulting in a peripheral movement of from 1 to 7 metres per minute, until the coating, while cooling and hardening, has been distributed in a uniformly thick layer within the tube. Bituminous materials are suitable for the lining, and the rotational speed of the tube is preferably reduced as the liquid grows colder and more viscous. Cooling may be accelerated by blowing a stream of air through the tube, or by the application of water or of compressed air to the external surface of the tube.  According to the Specification as open to inspection under Sect. 91, shortly before the lining has completely solidified, the speed of rotation of the tube may be increased to give a peripheral speed of about 45 meters per minute, to adjust any very small irregularities in the thickness of the lining, but this subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specification 274,565, [Class 99 (ii)].ALSO:Cylindrical tubes are lined by causing a hot liquid coating material to flow within the tube by slow rotation thereof, resulting in a peripheral movement of from 1 to 7 metres per minute, until the coating, while cooling and hardening, has been distributed in a uniformly thick layer within the tube.

A mainspring winding device for a clock mounted in a tachograph comprises a ratchet wheel 12 mounted for rotation with an arbor 6, a winding lever 15, a feed-pawl 17 which is movable in response to winding movement of the lever to drive the ratchet wheel and a detent 20 to prevent reverse rotation of the ratchet wheel. The pawl 17 is secured to a plate 14 by a pin 18, the plate and the lever 15 being mounted on a hub 13 on the arbor 6. The pawls 17, 20 are biased by springs 19, 22 towards the ratchet wheel which they engage at points defining an angle #. A reciprocating rotation of the lever 15 similarly rotates the plate 14 and therefore causes the pawl 17 to rotate the ratchet wheel thereby winding the spring 11 when the pawl moves in one direction. A spring (23), Fig.3 (not shown), returns the plate each time to an initial position defined by the abutment of the pin 18 with a plate 8. During the initial movement of the pawl 17 the plate 14 is not subjected to the restoring force of the spring (23) so that the pawl is freely slidable along the surface of the tooth with which it is in engagement until it abuts the edge of the next tooth whereupon it drives the ratchet wheel, the plate 14 then being subjected to the restoring force of the spring. The clock housing 5 ispivotally mounted in the tachograph housing.

Abstract: 611,615. Grinding-machines. SOC. D'APPAREILS DE CONTROLE ET D'EQUIPEMENT DES MOTEURS S.A.C.E.M. June 5, 1945, No. 14135. Convention date, Aug. 14, 1943. [Class 60] [Also in Group XXII] A machine tool is characterised in that the relative movement between a tool and a work-piece to be machined is obtained, on the one hand, by the usual feed mechanism of the machine and, on the other hand, by a reduced finishing feed, which is independent of the normal feed mechanism and is obtained by the resilient deformation in the direction of its feed movement, of a part of the machine partaking of the movement of the member (tool or work-piece) to be moved, by the action of an adjustable constraint applied to the said part. As applied to a grinding machine with a main frame 1, Fig. 1, carrying a work-holder 7 and a grinding wheel carriage 2, with wheel 3, given a normal feed by a screwed rod 4, the finish-feed stressing means comprises a lever 8 pivoted, at its upper end to a horizontal rod 10 connected to the carriage 2, and at its lower end to the main frame 1, and acted on by a rod 12 screwed by a hand-wheel 11 against the action of a stressing spring 14, into a knuckle 13 in the said lever 8. The deformation produced by a definite amount of stressing is measured either by apparatus 15 or by reading the experimentally graduated hand-wheel 11 or by a pneumatic measuring apparatus. In operation the grinding wheel 3 is first given a normal feed by means of the rod 4, the hand-wheel 11 is then turned a predetermined amount to compress the spring 14 and apply a stress to the carriage 2 which stress will deform the carriage towards the work, thus giving the required finishing feed. As applied to a centreless grinder with a grinding wheel 19, Fig. 2, and driving wheel 20, the finish feed stressing means comprises a threaded rod 25, screwed into a socket 27 adjustably fixed in a main frame 18, and extending through a driving wheel carriage 21 between which and a shoulder on the rod on one side, and a handwheel 26 on the other side, two springs 29, 30 are provided so that stress can be imposed in either direction.
