Abstract: 1,130,168. Making spools; shearing; punching; jointing by forging ; chaplets; double heading. RUMANIA, MINISTRY OF LIGHT INDUSTRY. 28 Oct., 1965, No. 45749/65. Headings B3A, B3F, B3H, B3U and B3W. An apparatus for making spools or chaplets comprises means to feed a pair of strips 30 to a punching machine where holes are punched in the strip and discs each with a hole at their centre are punched from the strip, means to feed wire B to a cutter 23 where lengths are cut-off and means to position the cut-off length between a pair of the discs which are riveted on to the length. The strips are fed through straightening rollers by reciprocating feed grippers, Fig. 3 (not shown), which comprise a pair of opposed housings (41) each with a roller (42) which co-operates with the opposed roller to grip the strip in one direction of reciprocation and roll over the strip on the return stoke. A separate gripper is provided to prevent retrograde movement of the strip. Holes are punched in each strip by piercing punches (51), Fig. 5 and the holes are centresunk. A disc (a) is then blanked out of each strip by further punches (52). A pair of punches (51), (52) are mounted on a common housing (31), Fig. 1b (not shown), and reciprocated by a cam (32). Simultaneously the wire is fed by a reciprocating gripper 20 through dies 36 with which the cutter blade 23 cooperates. The cut-off wire is fed to a disc 27 which moves the wire between the discs blanked from the strip. The blanking punch (52), in addition to blanking the disc, also rivets the ends of the cut-off wire (b) to each disc, Fig. 5C (not shown). A beam 34 is moved by a cam to hold the wire in a groove on the disc 27 during the riveting. The formed spools or chaplets 38, Fig. 4 (not shown), are removed from the disc 27 by a fork. The waste strip material is coiled on a drum (40).

Abstract: 458,246. Starting. CROSSLEY-PREMIER ENGINES, Ltd., and YEATES, A. C., Sandiacre, near Nottingham. July 23, 1936, No. 20390. [Class 7 (v)] For starting a multicylinder engine, a compressed-air or electric motor g, controlled from a distance by a valve or switch, drives through worm gearing h, i a cam k which actuates a valve m for the supply of starting air to the engine cylinders, valves n, o for passing compressed air to means for relieving cylinder compression, a valve t controlling the flow of engine cooling water, and a trip device u for bringing the motor to rest, for example by turning off a compressed-air valve v. The valves n, o may each control compression in half the cylinders of the engine, by admitting compressed air to pistons operating parts which hold the exhaust valves open. On rotation of the cam k by the motor g, a cam surface p allows a lever r to fall to open the water valve t and the cam opens the valves w, n, o to effect starting. The valves o, n close in succession, allowing full compression to be restored in the two halves of the engine in turn, the starting-air valve m then closes, and finally the trip member u turns off the valve v and stops the motor. For priming the lubricating system of the engine, an oil pump is driven from an extension of the worm shaft h. The worm gearing and cam can be reset after a starting operation by means of a hand wheel w.

Abstract: Electrostatic flocking apparatus is characterised in that the base of a flock supply container comprises a series of clothed rollers arranged side by side in resilient contact with each other, all the rollers being driven in the same direction of rotation.  The rollers may conveniently be clothed with bristles or a soft elastic material e.g. a foam material, and the distance between the axes of rotation of adjacent rollers may be varied. The rollers may be of differing diameters and the height of each rollers may be adjusted relative to the adjacent rollers.  In a preferred embodiment the material to be flocked is passed over an earthed supporting track and a sieve at high tension potential is disposed intermediate the base of the flock container and the supporting track, Fig. 1 (not shown).  In an alternative embodiment, Fig. 2 (not shown), the series of rollers is arranged to pivot about a substantially horizontal axis parallel to the axes of rotation of the rollers, and to be locked in an inclined position.  The same effect may be achieved by arranging the series of rollers with progressively increasing diameters from one end of the series to the other.  In a further embodiment, Fig. 3 (not shown), an intermediate series of rollers, at a high tension potential, is disposed between the base of the flock container and the sieve.
