Abstract: 743,552. Endless belt conveyer driving gear. BABCOCK & WILCOX, Ltd. June 23, 1954 [June 23, 1953], No. 17393/53. Addition to 619,075. Class 78 (1). The conveyer belt drive of the parent Specification is modified in that each hydraulic coupling is of a form such that, with its input shaft driven at constant speed, its output torque may, during starting, be gradually increased. As shown, two driving drums 2, 4 located in the return run at the discharge end of the belt 18 are driven separately by squirrel cage motors through hydraulic couplings of the scoop type, wherein the scoops may be adjusted to vary the fluid contents of the couplings and therefore their torques, 30 and 32 being snub rollers. Roller 32 is adjustable for take-up as may also roller 52 at the feed end of the belt. A weighted vertically slidable roller 38 between the driving drums and the feed end on the return run regulates the tension drop across the driving drums so preventing slip occurring. Preferably to avoid slip during starting a further driving drum 48 driven through a hydraulic coupling of the traction type is located in the return run adjacent the feed end of the belt a take-up roller 50 and a weighted roller assembly 51 being interposed between it and the feed end. Alternatively as shown in Fig. 4 the feed end roller 53 may be driven through a hydraulic coupling of the traction type and the drive and roller assembly may be slidable as a unit so that tension may be applied to the belt by a weight 54. For a reversible belt conveyer all weighted roller tensioning devices and the further driving drums are duplicated on each side of the unit comprising the drums 2, 4 which is located half way along the return run, means being provided for energizing the motor only of that further driving drum which for that particular direction of movement is located at or adjacent the feed end of the belt. Stops are provided for limiting the upward movement of the weighted tension rollers on each side of the drums 2, 4.

[Also in Division B6] The tip 36, Fig. 6, of a ball point pen is made by the deformation under pressure of a billet of ductile material. The latter may be of electrolytic copper, aluminium, tin alloy or silver, or a billet may be plated with silver so that the plating appears on both the inside and outside of the pressed tip; non-metallic materials may also be used. A cold hollow billet is pressed preferably with impact by a punch 17, Fig. 4, within a hollow die 12 closed at one end by an abutment 14 carrying a core pin 13 which shapes the inside or cup of the tip 36. The rim 29 is formed by direct extrusion and the tubes 27, 28 by backward extrusion. A billet locating pin 18 within the hollow punch 17 is withdrawn as the backward extrusion proceeds. Depressions 25 in the pin 13 form spaced mounds 32, Fig. 13 (not shown), which are depressed subsequently to spherical shape by the inserted ball 35 or by a ball tool to provide a spherical seat therefor with intermediate ink passages. The extremity of the tip is also deformed around the ball. An ink reservoir 37 may be secured within the tube 28 by drawing through a die 39. In another embodiment, Figs. 7-12 (not shown), a solid cylindrical billet is used and in further embodiments, Figs. 13-24 (not shown), solid spherical billets are used. In both these cases a central wad is punched out after the extrusion. Specifications 564,172 and 609,817 are referred to.

Abstract: 595,937. Copying-telegraphy. FINCH, W. G. H. July 10, 1945, No. 17569. Convention date, March 25, 1944. [Class 40 (iii)] In a facsimile receiver signal-modulated light is obtained from an electron ray tube of the "tuning-eye" type. A mask 92 (Fig. 2) has a perforation 93 covering one half of the no-signal shadow area of an electron ray tube. Received picture signals are applied to the triode grid of the tube to cause the fluorescent area 16 to increase. Thus the edge 118 of the fluorescence moves into the area of the aperture 93, and the illuminated area visible varies in accordance with the received signal. The no-signal shadow area may be restricted by suitable biassing of the triode grid to the. size of the aperture 93 so that received signals cause both edges of the fluorescent area to enter the aperture. The aperture 93 is optically focussed on to a photographic recording sheet 45 and in order that the light spot on the film may not consist of a dark area together with one or two illuminated areas, the lens system 102 (Fig. 1) may be arranged slightly out of focus. The electronray tube is mounted in a box 51, having the optical system 96 screwed into a tapped hole 95 in its front plate, and this hole covered by the mask 92. The recording film 45 is mounted on a drum 31, rotated by motor 22 which also drives a worm shaft 41 to cause the scanning system 51 to traverse the drum longitudinally. At the end of its traverse, half-nut 53 pivots on a pin 52 and the scanning system may be returned manually or automatically to its start position ready to scan another line.
