Title: Improvements in or relating to earthenware conduits and their manufacture
Inventor: SMITH OSCAR HARRIS
IPC: B28B21/96
Filed: 1956-09-11
Abstract: 805,237. Conduits. HEPWORTH IRON CO. Ltd. Sept. 5, 1957 [Sept. 11, 1956], No. 27704/56. Class 33. An earthenware conduit is provided round the external surface of its spigot end and/or round the internal surface of its socket end with peripheral undercut grooving. Apparatus for doing so comprises a tool of generally dovetail form, means for advancing the tool into the conduit until the groove depth is reached, means for passing the tool round the conduit at that depth and means for withdrawing the tool from the conduit after at least one traverse of the conduit. In said apparatus a pair of tools 49 with tips 50 of generally dovetail form is attached to a bracket 48, carried by a lever 47 with a pivot 46 and having an arm 51 interacting with a plate 30 (screwed to an end of the sleeve 17) through an adjustable headed screw 53 upon advancing a finishing head 10 having blades 40, 42 for external and internal surface removal, respectively, in so doing. The head 10 is on a rotated shaft 11 driven through a key 12 connected to a pulley 13 having a double belt 14 to slide a distance X. The sleeve 17 is thus rotated and because of a pin 18 in a slot 19 in the shaft 11 the sleeve 17 can move axially a distance Y thereon against a compressed spring 20. The sleeve 17 moves on bearings 23, 24 in a sleeve 25 sliding axially in a liner 26 in the casing extension 27, a sleeve projection 28 being externally moved by means not shown to do so. The shaft 11 passes through the plate 30, a guard 32 being screwed to the extension 27. The pulley 13 has an integral pulley 35 which drives a trimming mechanism (not shown). Because of the rotation of the head 10 and parts thereon and tools 49 are held in the inoperative position and clear of the conduit by centrifugal force, Fig. 1, before advance of the head 10 by moving shaft 11 the distance X to engage spigot-end 37 with flange 45. After at least one revolution, when the blades 40, 42 will have acted, and the spigot-end 37 is engaged by the flange 45, the sleeves advance the distance Y. Plate 30 thus advances to rock the lever 47 and the tips of the tools 49 cut at the desired depth to form grooves. After the tools have traversed the spigot-end 37 at least once, the plate 30 is moved in a reverse direction the distance Y. The lever 47 is rocked so that the tips 50 come out of the grooves. Any ragged edges thereof are smoothed by the blade 40 operating all the time until the reverse movement is increased by the distance X, for the head to become inoperative. Simultaneously with the external grooving of the spigot-end 37, the inside of the socket-end of the conduit 38 may be grooved by a modified head in a similar manner. The grooving may be provided at one end only, the other end then having spaced depressions as described in Specification 805,238.

Title: Improvements in or relating to the manufacture of glass
Inventor: BUTLER KENNETH JAMES
IPC: F15B9/17
Filed: 1965-07-02
Abstract: <PICT:1093091/C1/1> In apparatus for treating a continuously advanced length of glass the treating device is controlled to travel in synchronism with the glass by a system in which pulses corresponding to the speed and position of the glass and the device respectively are compared. The invention is applied to the severing of constant lengths of tubing for fluorescent lights; the desired length is set on a counter 61 coupld to a pulse generator 30 actuated by the tubing 3 and at a predetermined count above zero a ring gas burner 13 is advanced by a servo-controlled hydraulic ram 36 to heat a local area of tubing which eventually meets a hinged metal chill block 6 and the prescribed length 7 breaks off due to its own weight and drops on to a conveyer.  The burner drives an endless chain 24 which operates a pulse generator 27; pulses from this and 30 are applied to a gate 60 which is enabled at the desired count to pass the pulses to a bi-directional counter 72, the resulting count above or below a datum number at any instant representing the positive or negative positional error of the burner relative to the tube.  This count is converted at 74 to an analogue current value which is amplified at 76 to operate the hydraulic control valve 45.  Velocity and acceleration terms derived in a differentiating unit 86, are added in the amplifier 76.  When the tube length counter 61 reaches zero a reset signal is generated and a circuit 79 initiates a burner return motion which is stopped by a signal from a magnetic detector 81.  The hydraulic, counting and electronic circuits are described in detail (see Divisions F1, G4, H3, respectively).
