Title: Improvements in and relating to combined moving picture and sound reproducing machines
IPC: G03B31/00
Filed: 1927-11-21
Abstract: 310,295. Cortella, A. Nov. 21, 1927. Phonographs associated with kinematographs; multiple record machines.-A combined picture taking or projecting apparatus and sound recording or reproducing apparatus is constructed with two or more units each comprising a turntable, motor and associated picture taker or projector, and the motors are connected by an electric circuit controlled from the units whereby after predetermined times one motor and its associated machines is automatically cut out and the motor of another unit started. The controlling means described are commutators on various shafts of each unit connected in series and designed so that after the necessary time for playing a record on the turntable a circuit is completed to effect the change over to another unit. Fig. 1 shows two turntables 14, 15 on spindles 12, 13 controlled by governors 20, 19 and geared with shafts 6, 7 actuating the picture taking or projecting apparatus 8, 9 so that the shafts 6, 7 make one revolution for each revolution of the turntables. These shafts carry commutator discs 25, 26 and are geared with vertical shafts 28 carrying commutator discs 32, 33 so that these rotate once for twenty revolutions of the turntable. The shafts 28 are geared with horizontal shafts carrying commutator discs 42, 43 so that these make one revolution for 360 revolutions of the turntable equivalent to complete playing of a record thereon. The commutator discs each comprise an insulator disc 43a, Fig. 3, and a conducting disc 44 having a projection 45 overlying the insulator disc so that when this part is carried below brushes 46 they are electrically connected. Fig. 4 is a wiring circuit showing a driving motor 54 for the turntable 14 and the associated commutator discs 25, 32, 42, and a driving motor 57 for the turntable 15 and the associated commutator discs 26, 33, 43. With the switch lever 55 in the position shown the motor 57 is connected with the supply circuit 47, 48 and drives the turntable 15 until after 360 revolutions a circuit is completed through tha brushes of the discs 26, 33, 43 connected in series and through a relay coil B which moves the switch 55 to break the circuit to the motor 57 and complete, that to the motor 54 of the turntable 14. A record on turntable 14 will now be played until after 360 revolutions a circuit is completed through the commutator discs 25, 32, 42 and relay coil A to move the switch 55 again. Continuous reproduction is thus obtained through the pick-ups 60, 65 connected respectively to amplifiers 59, 64 and a loud speaker 61. The pointer for the amplifiers is supplied from the main 47, 48.

Abstract: 1,142,786. Yarn-entraining device. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 July, 1966 [22 July, 1965], No. 31247/65. Heading DID and D1F. A device for entraining a yarn or filament away from the position where it is being processed, severing an unwanted portion and passing it to a waste disposal system, while maintaining the tension in the rest of the yarn, is such that when it is brought near the material in lengthwise movement, a part of the material is acted upon by at least one stream of fluid so that the material suddenly becomes fully enclosed within a cavity communicating with a disposal pipe, the material within the cavity simultaneously becoming acted upon by at least one stream of fluid so as to apply to the material a force in the direction away from the feed source of the material, the material being simultaneously severed by means attached to the device, and entrained and directed down the disposal pipe. As shown, a tube 6 surrounded by a jacket 5 has a narrow slot 10 at its front. Along the length of the slot near its edges are provided inwardly and downwardly directed apertures communicating through the jacket with pressure-air admitted through a pipe 9. At the lower end of the slot are cutting blades 12, 13 and at the end of the tube, a disposal device 7. The device is brought near the material with the slot either parallel to it or at an angle to it. In the latter case, part of the yarn is first entrained in the top of the slot: the rest of the yarn follows when the device is pivoted about its top to bring the slot parallel to the material. To ensure a clean cut and avoid damaging the yarn, a check device is provided to impede the movement of the yarn towards the cutter, until an appropriate force acts on the yarn near the cutter.

A lifting platform 1, adapted to be raised by projections 30 on rods 7 suspended from a cross-member 29 on the piston rod 28<SP>1</SP> of a hydraulic ram 28, is supported in its uppermost position, Fig. 1, by pawls 2, 2<SP>1</SP> engaging notches 6, 6<SP>1</SP> in the platform and may be supported in other positions by engagement of the pawls with projections on the rods 7. Further pawls 23, 23<SP>1</SP> are adapted to engage notches 24, 24<SP>1</SP> in the platform in its uppermost position if the pawls 2, 2<SP>1</SP> fail to function correctly. The pawls 2, 2<SP>1</SP> are mounted, together with cams 3, 3<SP>1</SP> and toothed sectors 4 on rotatable shafts 5, 5<SP>1</SP> and, in their inoperative position shown in Fig. 2, a pressurized ram 8 maintains, through a bell-crank lever 15 and link 14, a Z-shaped member 13, pivotally mounted at 13<SP>1</SP>, in the position shown in which it prevents rotation of the cams 3, 3<SP>1</SP> through the action of a link 12 and a weight 9 on a lever 10 which tends to rotate in a counterclockwise direction about a stop 11 on the platform 1 when the platform is in its uppermost position. On releasing the pressure in the ram 8, the lever 10 is free to pivot about the stop 11 and to rotate the pawls 2, 2<SP>1</SP> into engagement with the notches 6, 6<SP>1</SP>. The pawls are disengaged from the notches by applying pressure to the ram 8. Simultaneously with the operation of the pawls 2, 2<SP>1</SP>, pawls 23, 23<SP>1</SP> are swung outwardly into notches 24, 24<SP>1</SP> on the platform by means of a weight 17, a bell-crank lever 18 and a rod 19 which acts on levers 20, 21, Fig. 5, and drivers 22. A space is provided between the pawls 23, 23<SP>1</SP> and the notches 24, 241 whereby the pawls are effective only on failure of the pawls 2, 2<SP>1</SP>. The pawls 23, 23<SP>1</SP> are released from the notches 24, 24<SP>1</SP> by applying pressure to a hydraulic ram.25.  In positions other than the topmost position, the platform 1 is supported by the rods 7 and when the platform is lowered, together with the stop 11, the weight 9 causes a lever 10<SP>1</SP> to bear against a fixed stop 16, and rotates the cam 3 and pawl 2 in a counterclockwise direction to engage the pawl with the rod 7, provided the pressure is released from the ram 8. In operation, in the event of a failure in a ram 28, when the ram is lowered in relation to other lifting rams, the entire installation is halted through electrical control devices (not shown), whereby the ram 8 is automatically relieved of pressure and the weight 9 causes locking of the pawls 2, 2<SP>1</SP> with the rods 7.

A three-position control valve 11 for a double-acting motor 12, for raising and lowering the bucket-carrying boom 13 of a loader, has inlet and exhaust ports 14 and 16 which are connected to a reservoir 17 and a bore encircled by seven annular chambers 21-27. Chambers 23 and 25 are connected to the inlet port 14 via passage 28 in which is a relief valve 32, chambers 21, 24 and 27 are connected to the exhaust port via manifold 29 and chambers 22 and 26 are connected with the motor ports. Chamber 22 has a longitudinal extension 31. A hollow valve closure member 33 has two annular grooves 34 and 35 with three lands 36-38; and two axial bores 39 and 41 extend into the member 33 from either end, whilst radial bores 44, 45 and 47, 48 extend from each bore, each bore also containing a check valve 46, 49. Plugs 42, 43, close the outer ends of the bores. The end faces of lands 36, 38 contain conical undercuts 51, 52, intersected by radial passages 53, 54, whilst a check valve 50 seats on the end of 1 and 36 and encircles the member 33. In the neutral position of the plunger, 1 and 36 and 38 isolate chambers 22, 26, and so hydraulically lock the motor, and fluid from pump 15 passes through passage 28, chambers 23, 25, grooves 34, 35, chamber 24 and manifold 29 to reservoir 17. To raise the boom 13, the member 33 is moved to the right to interrupt communication between ports 14, 16, and connect passages 44, 45, 48 and 47, with chambers 22, 23, 26 and 27 and passage 53 with chamber 24. Port 22 is connected to the pump 15 by means of passage 28, annular chamber 23, radial passages 45, bore 39, check valve 46, radial passages 44. Fluid then passes along conduit 18 to the rod end of the motor whilst fluid from the head end is discharged by conduit 19 to the reservoir 17. The boom 13 is locked into position by moving the member 33 into its neutral position. To lower the boom 13 the member 33 is moved to the left and the head end of the motor is connected to the pump 15 similarly to before, whilst the rod end discharges fluid to the supply passage 28 and through check valve 50 to the reservoir 17. When the boom has passed through its vertical position in any one movement, the pressure required to continue this movement lessens, but stability of the fluid is maintained by the check valve which is kept shut by its spring on raising the boom and is opened to release discharged fluid to the reservoir 17 on lowering the boom. To prevent cavitation, a second valve 55 and extension 31 may be fitted adjacent the undercut 52 and the groove 26 respectively. Specification 812,490 is referred to.
