Title: High mast winch arrangements
IPC: B66D1/04
Filed: 1974-10-11
Abstract: 1504880 Winches GENERAL ELECTRIC CO Ltd 10 Oct 1975 [11 Oct 1974] 44105/74 Heading B8B A winch having primary 1 and secondary 2 drums for winding a pair of ropes simultaneously in normal usage, comprises a turning handle 29 for operating the primary drum shaft 8 and a sleeve 12 which through a chain 13 drives the secondary drum shaft 9, and latch bars 17, 21, 25 associated with the sleeve 12 and drum shafts 8, 9 facilitating either rotary drive of the primary drum only for rope balancing purposes, or rotary drive of both drums. The latch bar 21, pivoted to a fixed shaft 22, includes a slot 20 gravitationally engageable with pins 19 projecting from the primary shaft 8, this bar 21 being connected by a flexible link 27 to a similar latch bar 25 engaging pins 23 on the secondary shaft 9, whereby the bar 25 is lifted clear of the pin 23 as the bar 21 is lifted clear of the pins 19 by the chamfered end of a tubular sleeve 30 of the handle 29 as it is pushed over the shaft 8. Slots 31 in the handle sleeve 30 receive the pins 19 whereby rotation of the handle is transmitted only to the shaft 8 or drum 1. As the sleeve is pushed further, it slides over the sleeve 12, freely rotatable on the shaft 8, and raises the latch bar 17 free from pins 15 on the sleeve which pins are received in the handle slots 31 to be rotatable thereby. Rotation of the handle in this position rotates the primary drum 1 and also the secondary drum 2 through the sleeve 12, chain 13 and shaft 9 which has previously had its latch bar lifted. The handle may be replaced by a motor drive. In another embodiment, Fig. 3 (not shown), the secondary shaft is driven through a manually selectable clutch, directly from the primary shaft.

Abstract: 1441297 False twister SKF KUGELLAGERFABRIKEN GmbH 2 Oct 1973 [7 Oct 1972] 46019/73 Heading D1D In a false-twister, a plate carrying twist tube drive and support means is pivotally mounted at one of two pivoting points enabling the drive means to be spring-biased against opposite sides of a drive belt to reverse tube rotation. As shown, Fig. 1 (left hand), plate 1 carries magnet 6 urging twist tube 7 against plate-mounted rolls 4, 5 having wharves 8, 9. Plate 1 is pivoted on fixed carrier 12 about pivot 11, 17a and is urged clockwise by spring 18 so that wharve 8 engages belt 10, which is also engaged by carrier-mounted roller 23. To disengage wharve 8 the plate is manually pivoted anti-clockwise and spring 18 moves over-centre to urge the plate against wall 16. To reverse the rotation of tube 7, Fig. 2, the plate is repositioned to pivot about pivot 11, 7b, and spring 18 is repositioned to pivot the plate anti-clockwise so that wharve 9 engages the opposite side of the belt. Roller 23 is repositioned on the other side of the belt. Angle α never exceeds 80‹ to allow access to the tube support. In a modification (Figs. 4 and 5 not shown) two adjacent plates 1 are linked so that they may be pivoted in unison. Alternatively, Fig. 6 two plates 1 are pivotally mounted on arms 13a, b of common carrier 13 on opposite sides of the belt, so that their tubes are rotated in opposite directions. The plates are pivotally connected by link 7 so as to be capable of movement in unison, in opposite directions, to and from the beltengaging position. Link 27 may be loosely connected to pins 28, the resulting backlash in motion allowing the springs to act independently on their plates. Plates mounted on separate carriers may be similarly linked.

Abstract: 1332366 Polypropylene compositions GENERAL ELECTRIC CO 29 Sept 1970 [29 Sept 1969] 46359/70 Heading C3P [Also in Division H1] Polypropylene film for use as a capacitor dielectric is manufactured by mixing particulate polypropylene resin with a liquid dielectric impregnant which is a halogenated. diphenyl, castor oil or mineral oil and forming one mixture into a film. Further impregnation after assembly of the capacitor is thus facilitated or obviated. Preferably a film comprising 1 to 20% by weight of impregnant is made by adding, e.g. trichlorodiphenyl to the resin in flake form and agitating in a blender to obtain a free-flowing powder which is dry to the touch. The film may be prepared by hot-pressing, extruding or the blown tube process. The impregnated powder may also include an epoxide stabilizer. The capacitor may be further impregnated by known methods and heated to achieve the "substantially complete impregnation" forming the subject of Specification 1,169,038. Optionally the capacitor roll may include a "widening" strip of porous material. Instead of polypropylene, a blend thereof with another polymer, or a copolymer of propylene and another monomer, may be used.

[Also in Division H3] In a pulse generator for spark erosion equipment, a thyratron or silicon controlled rectifier (SCR) 5 is triggered by pulses from 7 so as to initiate breakdown of erosion gap 6. SCR5 is quenched by triggering SCR8 which discharges capacitor 10 in the reverse direction through SCR5 and recharges capacitor 10 via diode 13 with reversed polarity until SCR8 becomes self-quenched. The next pulse from 7 simultaneously triggers SCR's 5, 9, initiating another pulse across gap 6 and allowing the charge on capacitor 10 to be reversed by inductor 11. In Fig. 1 (not shown) components 8, 10 are connected across SCR5, capacitor 10 recharging via a resistor connected across the gap 6. In Fig. 3 (not shown), SCR9 is replaced by an uncontrolled rectifier and a further inductor (not mutually coupled to inductor 11) is included in series with SCR5. The gap 6 may be operated under water.

The apparatus shown in Figs. 1, 2 and 3 is substantially the same as that described in U.K. Specification 1,119,965. The assembly 38 comprises depending pusher finger 48, 50, Figs. 4 and 5, to engage standard couplers 56 of the rotary type. When the fingers are engaged with the couplers 56, the assembly 40 which is formed of pivotal arm couplers 42, 44, are in folded stored and inclined positions, Figs. 5 and 6. When the cars of the train are of the type which have non-rotary couplers and have to be uncoupled before entering the dumper, the arm 14 is moved to a downwardly inclined position, Fig. 8 (not shown), with the arm couplers 42, 44 manually pivoted to oppositely directed positions, Fig. 9 (not shown) for engaging couplers of cars which are uncoupled and spaced by the carriage 15.
