Abstract: 617,201. Hydraulic motors. BRITISH CELANESE, Ltd. July 3, 1946, No. 19900. Convention date, July 4, 1945. (Class 69 (ii)] [Also in Group IX] Hydraulic means are included in a yarn twisting and winding machine for reciprocating the horizontal traversing bar that effects the vertical reciprocation of the traverse means for a series of vertical spindles. Oil from supply 48 is delivered by a constant-displacement type pump 52, driven by a separate motor 53 or by an element of the twisting machine, to the ports 35 of the cylinder of a distributing valve 28, the piston 33 of which is reciprocated by airpressure supplied through pipes 41, 42, the air supply being governed by an oscillating valve 37 moved by rack-and-pinion mechanism from the plunger 19 of the hydraulic cylinder 17, the oil distributed by the valve 38 entering the cylinder 17 through pipes 36. The other end of the plunger 19 oscillates through rack-and-pinion mechanism a cam 79 which reciprocates a rod 45 to oscillate levers 67 'about their pivots 68 to latch, or trip, dogs 63 so that the piston 33 is latched at each end of its stroke. The reciprocating rod 45 is operated by the cam 79 through a free-wheel device 76 including an eccentric sleeve, so that the latching of the distributing valve piston 33 is changed by small amounts, first in one direction and then in the other, so to prevent piling of yarn at the ends of the traverse. Eccentrically pivoted spur wheels 27, also oscillated by the rack-andpinion mechanisms at both ends of the hydraulic plunger, move chains 88 attached thereto to reciprocate the horizontal bar 89 which in turn moves chains 91 attached to lifter rods 93 to reciprocate the two ring rails 12, 13, the arrangement being such that one rail is rising whilst the other is falling. Specification 594,552 is referred to.

[Also in Division H2] In a hand tool, similar to those described in Specifications 1,026,970 and 1,008,673, for making electrical connections, a clip pusher 34 engages the leading terminal clip 2<SP>1</SP> of a strip of terminals by means of the inwardly turned ends (42) of a pair of arms (41) mounted in a recess of the clip pusher 34 (Fig. 7, not shown). Forward movement of the pusher moves the strip forwards and the leading clip 2<SP>1</SP> is severed therefrom, movement of the strip being prevented by abutment with a stop 74. The clip 2<SP>1</SP> moves against a wire 12 and drags it over the upper surface of a mandrel 46 and a scraper 82, which removes part of the insulating film on the wire. The tool is applied to a terminal post (14a) (Fig. 4, not shown) with a shoulder 51 on the mandrel disposed against the top of the post. The tool is pushed against the post to bring about a further movement of the pusher 34 relative to the mandrel 46 and the clip is driven to the lower end of the post. The tool is reset and a suitable length of wire is pulled from a spool (90) (Fig. 1, not shown) thereby allowing a number of posts (14a, 14b, 14c, 14d) to be interconnected by applying the tool to them in succession. When using wire having relatively thick insulation, the wire is bared at the required locations before the terminals are applied.
