Title: Connecting plug for an electric courrent supply conduit
IPC: H01R25/14
Filed: 1972-09-04
Abstract: 1398317 Connection plugs for current supply rails OY NOKIA AB 4 Sept 1972 [6 Sept 1971] 40938/72 Heading H2E A plug comprises a casing 1 with contact fingers 4, 5 each comprising an arm supported at one end in the casing and carrying a contact at the other end adapted for engagement with conductors 9, 10 in a support rail, each contact finger being movable between a projected position in which it connects a conductor and a withdrawn position in which it is within the casing by means of displacing a plate-like slide 2 which moves over the arms with a camming effect. The track comprises an insulating strip 16 carrying the conductors 9, 10 and mounted in an aluminium support rail 11 fitted with an earth conductor 12. As well as the contact fingers 4, 5, the plug carries gripping fingers 3, (3<SP>1</SP>), 6, (6<SP>1</SP>) each comprising an arm 24, 25 for gripping edges of the rail to hold the plug therein. The fingers 4, 5, 3, (3<SP>1</SP>), 6, (6<SP>1</SP>) pass through a respective slot 22, (23), 19. (20), 18, (21) in the plate 2 and the arms are shaped such that as the plate 2 is moved from the full line position to the broken line position of Fig. 6, the slots bear against the arms to project the fingers for engagement with the track, the arms being resilient and unstressed in the withdrawn position. The contact and gripping fingers and earthing fingers 13, (13<SP>1</SP>) are all screw mounted to an insulating bar 17. Polarization is achieved by provision of assymetric projections (14, 15) on the plug. On inserting the plug into the track the earthing fingers make connection initially due to their own resilience, but this connection is enhanced by the gripping fingers which press against the earthing contacts as well as gripping the track.

Title: Governor valve mechanism

Filed: 1975-10-09
Abstract: 1483027 Change-speed control FORD MOTOR CO Ltd 9 Oct 1975 [29 Nov 1974] 41361/75 Heading F2D Two-stage governor pressure, for controlling ratio shift in an automatic transmission on a motor vehicle, is provided by a governor valve secured to the output shaft and having primary and secondary valve spools 22, 20, connected by a cross-over passage 50, in which, during a first stage, pressure modulated by the primary spool 22 acts radially inwards on the outer area 52 of the secondary spool 20, in opposition to centrifugal force, and a spring 40 and assisted by governor outlet pressure 38 acting inwards between differential lands of the secondary spool 20, regulating to exhaust 44, until, at a breakpoint, centrifugal force on the primary spool 22, opposed by a spring 58, and assisted by cross-over pressure 50 acting between differential lands, causes the primary spool 22 to bottom on a stop 62, fully exhausting the cross-over passage at 54, whereafter, during a second stage, the secondary spool 20 regulates at a lower parabolic rate unaffected by the primary spool 22. Independent shift point calibration in both stages is possible, and a pressure signal is possible at zero output speed. In Fig. 1 line pressure 36 is supplied to both spools through the passage 36 and a second cross-over passage 56. In Figs. 3 to 6, not shown, the second cross-over passage 56 is eliminated, the upper edge of the upper land (32<SP>1</SP>) of the secondary spool 20 metering line pressure 36 over the top of the spool into the single cross-over passage (50<SP>1</SP>) for regulation by the primary spool as in Fig. 1. In Figs. 7 to 9, not shown, the second cross-over passage (68) is retained, but is fed with outlet governor pressure instead of line pressure as in Fig. 1. Since the diameters of the various lands of the valve body diminish in steps from the lower end in Fig. 1 to the upper, the upper end of the bore can be blind, and the lands machined from the open lower end in one drilling.

Title: Improvements in driving arrangements of textile carding machines
Inventor: PRINCZ FERDINAND
IPC: D01G15/36
Filed: 1963-10-24
Abstract: 1,092,364. Carding engines. T. M. (RESEARCH) Ltd. Oct. 26, 1964 [Oct. 24, 1963], No. 42085/63. Heading DIN. In order that the doffer and feed members of a carding machine may run at lower than the normal operating speed to facilitate piecing, a change speed gear is interposed in the drive and is arranged to prevent an abrupt change in sliver thickness. The change speed gear consists of an infinitely variable speed unit controlled by a reversible motor that is started when a change of speed is required and stopped when a desired speed has been attained. Speed change may be initiated manually or automatically in response to a signal from a length measuring motion or from a stop motion, and upper and lower speeds are determined by stops mounted relative to a graduated disc and positioned to operate limit switches, Fig. 4 (not shown). The variable speed gear is of the kind in which a V-belt (Fig. 2, not shown), extends between members each consisting of conical half-pulley adjustable towards and away from each other. The adjustment is by pivoted levers connected by sleeves to a screwed shaft with opposed threads and driven by the reversible motor. The input side of the variable speed gear 16 is belt-driven from the taker-in 15, Fig. 1 and the output shaft 40 drives the doffer and burr-crushing arrangements 37. A side shaft 32 from the doffer drive carries the drive to the lap and feed rollers 34, 35 via worm gearing. An electromagnetic clutch and brake unit 23 is interposed between the output shaft 40 and the doffer for transmission of drive when energised. De-energision may be effected by a stop motion which is arranged not only to stop the doffer but to cause the control input of the variable speed gear to move to slow speed position so that on restarting the doffer it will rotate initially at slow speed. The length measuring motion may be caused to operate when a sliver can has been filled and is also arranged to move the variable speed gear to show speed position.

Abstract: 987,698. Fork attachments for tractors. J. F. WRIGHT. Dec. 5, 1962 [Dec. 5, 1961], No. 43596/61. Heading B8H. A A fork for mounting on a boom on a tractor or the like has tines 1 which are bolted to lugs 8 on a bar 4 and pass between sleeves 6 on a bar 3. The tines are prevented from pivoting by a bar 7 attached to end-plates 5 and by plates 9. A further bar 10 reinforced by an angle member 13 serves for pushing down trees and demolition work when the forks are suitably oriented. The fork is supported by pairs of arms 19, 23, Fig. 2, which are pivoted to pairs of plates 16 which interconnect the bars 3, 4. Abutments 24 prevent downward movement of the tines. Side plates may be provided to prevent the road falling off the tines. The fork may be rigidly attached to a boom instead of pivotally.

A jacking unit comprises a lifting post 10 formed with an external screw thread, two beams 11,12 with apertures 13,14 through which the lifting post 10 extends freely, two hydraulic jacks 17, 18 operatively connected between the beams 11, 12, two internally-threaded nuts 15, 16 engaged on the thread of the lifting beam 10, one against each beam and an electric motor (not shown) for rotating each of the nuts. The load, consisting of the preformed roof and floor of a building is secured to bolts 19 by nuts 20 which hold the load firmly against extensions 25 of the upper beam 11. Nut 16 is screwed up to beam 12 and the beam 11 raised by the jacks 17, 18, the nut 15 being rotated to follow the beam 11 so that on failure of the jacks the load is supported. Electrical circuits (not shown) ensure that the jacks can operate only when each nut 15, 16 is in contact with its associated beam 11, 12. After the jacks 17, 18 have completed their stroke the lower beam 12 is raised by driving the nut 16, thus retracting the jacks. The lifting post 10 may be raised by securing the load and rotating nut 16 in reverse so that it engages a plate 27 and then continuing the drive to screw the lifting post 10 upwardly, rotation of the post 10 being prevented by projections (not shown) on the beams 11, 12 engaging grooves 28 cut along the post 10 in diametrically-opposed positions.
