In a system for driving an alternator 2 at a constant speed from a variable speed shaft 1 by means of an eddy-current coupling 3, the operating speed range is extended by a changespeed gear 4 selected by a magnetic powder clutch 7. At low speeds, the drive is through the magnetic powder clutch, but at a predetermined speed, switch 8 de-energizes this clutch to permit drive through a freewheel 34 at a lower gear ratio. The switch 8 is preferably operated from an impulse generator 28, 29, 30 through a high-pass filter. The powder clutch consists of a fixed field member 7a and two rotatable members 7b, 7c, member 7b being driven by the input shaft 1 and 7c driving the high ratio gear-set 31 through hollow shaft 25. The free-wheel 34 drives the low-ratio gear-set 32 through shaft 17. The magnetic powder is retained in the air-gap between 7b and 7c by steel baffles 26, 27. Specification 853,977 is referred to.

Abstract: 845,933. Lubricating. CAVALLINI, S. Dec. 27, 1957 [March 15, 1957], No. 40172/57. Class 12 (3). [Also in Group XXVIII] An installation for automatically lubricating a knitting-machine, particularly a machine for making stockings, comprises a transparent oil container 1 which has a cover-plate 3 and houses a pump 4 consisting of a piston 10 working within a transparent cylinder 5. An oil filter 8 is removably attached to a rose 6 which is secured to the lower end of the cylinder 5 and accommodates a suction valve 7, a compression-spring 91 being constrained between the rose 6 and the piston 5. The latter has a non-return valve 13 located in its upper end and a central bore 12, the upper end of which is connected by radial bores with an annular space 14 communicating with a conduit 15 which is formed in a boss 27 in the coverplate 3 and is connected to a pipe for delivering the oil under pressure to an external distributer 16. The latter has distribution nozzles 17 and a nozzle 171 connected to a pipe 23 which returns any excess of oil delivered to the distributer back to the container 1. The machine to be lubricated acts at intervals on a pawl 19 which at each impulse received causes the rotation of a cam 22, bearing upon the upper end of a rod 18 which passes through the cover 3, and a packing 20 therein, and which is connected to the upper end of the piston 30. As the cam 22 rotates the piston 10 is urged downward against the spring 9<SP>1</SP> so that oil in the cylinder 5 is forced up through the bore 12, past the valve 13, and into the annular space 14. When the cam 22 has executed a full revolution a step in the cam allows the spring 9<SP>1</SP> rapidly to raise the piston 10 so that the oil in the annular space is suddenly pumped out to the distributer 16, replacement oil being sucked into the bottom of the cylinder through the valve opening 7. The cover 3 has an oil filling opening 31 and bosses 28, 29, for connection to a stationary support 30, a sealing gasket 3<SP>1</SP> being interposed between the cover 3 and the container 1.

Abstract: 1409113 Providing spoken indications of measured values MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 6 Sept 1972 [9 Sept 1971] 41312/72 Headings G1J and G1W [Also in Division G5] A measuring device includes playback apparatus which provides a spoken indication of the value of an analogue variable (e.g. speed, weight, length) and which comprises a record carrier 16 having a plurality of tracks 20 corresponding to discrete values of the variable, a carriage 32 displaceable transverse to the tracks by an amount proportional to the value of the variable, and a head 42 resiliently connected 36 to the carriage 32 to permit displacement of the head 42 relative thereto by up to one track spacing, in order to position the head on a track which is then played back on movement of the record carrier. This rounding-off always takes place in the same direction. As shown, a talking speedometer includes a cylinder 16 with spaced magnetic tracks 20 containing speech recordings of certain speeds. A shaft 53 rotates at a speed proportional to the speed to be indicated, and through a rotor 54 causes an endless belt 60 to move by one track spacing for each corresponding change in speed. The carriage 32 is secured to the belt 60. A head support 34 is located against a stop pin 38 of the carriage 32 by spring 36, both the carriage 32 and the support 34 being slidable along bars 30, 31. A depending portion of the head support 34 includes a knife edge 86 co-operable with teeth 85 on a member 64 which is pivotable about, and slidable along, a shaft 62. The teeth 85 each have a vertical and a sloping surface, and are spaced by an amount equal to the track spacing. When a reading is required, a motor 24 is energized to rotate a shaft 14 and the cylinder 16. Cam 98 and lever 92 pivot the member 64 to engage the teeth 85 with the knife edge 86. Cam 82, lever 76 and cord 70 then pull member 64 along the shaft 62 by a distance equal to one tooth spacing. Unless the knife edge 86 is initially positioned at a tooth apex, when head 42 is correctly positioned over a track 20, the knife edge 86 will at some point be engaged by a vertical tooth surface and moved until head 42 is correctly positioned. At the end of one revolution of the shaft 14, cam 98 causes a switch 100 to be actuated to de-energize the motor 24, and member 64 also returns to its initial position. The record carrier may be in the form of a magnetic disc (200), Fig. 2 (not shown), a gramophone disc with concentric grooves, or other sheets or tapes.
