Title: Improvements in vibratory feeders
Inventor: FORMAN ARTHUR WALTER
IPC: B65G27/00
Filed: 1968-03-19
Abstract: 1,256,225. Vibratory conveyers. DRIVER SOUTHALL Ltd. 11 March, 1969 [19 March, 1968], No. 13152/68. Heading B8A. [Also in Division G1] As shown in Fig. 1 material from a hopper 22 is discharged by a trough 23 into a trough 15. The trough 15 is carried from an intermediate mass 12 by torsion links 16. The mass 12 carries the trough 23 and is carried from a reaction base 11 by torsion links 13, the base 11 being mounted on springs 24. The links 13 and 16 are normally positioned at right angles to each other. The two troughs 15, 23 are vibrated by electromagnetic vibrator 10 vibrating in direction 14 and the rate of flow of powder through the trough 15 is controlled by an element 19 secured to the trough 15 and spaced from an element 21 secured to the base 11. The elements 19, 21 form a condenser in the control circuit which controls vibrator 10. Excessive material flowing in trough 15 displaces the links 16 relative to mass 12 to cause a change in the capacitance of the elements 19, 21. This change influences vibrator 10 to cause the flow to diminish in this way the flow of material is maintained stable. In the embodiment of Fig. 4, material from a hopper 422 is conveyed by a vibrating trough 444 to a vibrating trough 415 and then it passes on to a vibrating trough 446. Part of the material being conveyed along the trough 446 falls on to a coarse feed trough 447 which feeds it on to a coarse feed trough 449, the fine feed trough 446 conveying material on to a fine feed trough 448, the two flows of material passing into a weigh hopper 450. The trough 444 is vibrated by an independent vibrator 445. The trough 415 is carried from an intermediate mass 412 by links 416 which are counter-weighted at 443 and the mass 412 is carried by links 413 and vibrated by a rigid lever 440 from an hydraulic vibrator 410. The trough 448 is connected to link 413 and vibrates with it. Additionally a link 416 is provided with bellows 456, Fig. 5 (not shown), the trough 415 carries an element 458 which partially obstructs lamps 464 which shine on a photo-electric cell included in the vibrator circuit. In this way excessive material on trough 415 causes depression thereof and operates the photo-electric cell to influence the vibrator unit and thus to reduce the flow.  Operation.-When the weigh hopper 450 registers the required weight of material, magnet 452 moves along a reed switch 453 and operates the latter. This causes the vibrators to stop and operate a trap blade 454 to catch any material falling from the fine feed trough 448. Other transducer devices may be used such as a magnet co-operating with a reed switch or a bleed valve.

Filed: 1940-08-23
Abstract: 541,438. Telephone &c. transmission. STANDARD TELEPHONES & CABLES, Ltd. Aug. 23, 1940, No. 13397. Convention date, Dec. 13, 1939. [Class 40 (iv)] [Also in Group XL] A section E for matching the impedance of an open-wire line OL which may have various characteristic impedances to a lead-in cable LC which may have various lengths is applied between the end of the cable LC and the filter 6 and includes an adjustable series inductance L and adjustable condensers CA, CB. In the case of longer cables, a fixed impedance matching section G is added between a cable and the open-wire line. The system is particularly applicable to disc-insulated lead-in cables, which have a relatively high inductance and low capacity, and to a broad-band carrier system in which twelve carrier channels lying between 36 and 142 kc/sec. are separated by a filter 6 from channels lying below 31 kc/sec. It is concerned with impedance-matching designed to reduce cross-talk arising from reflection of the higher frequencies at the ends of the line. The section E is designed for a standard length of 125 ft. of cable LC whose capacity of 585 micromicrofarads forms one shunt arm of this section. For matching shorter lengths of cable a shunt condenser CA and a series air-core variometer L are adjusted to build out the inductance and capacity of the cable. The impedance of the filter is matched by an additional adjustable unit 5 in combination with a further shunt condenser CB for lead-in cables of intermediate length (up to 150 ft.) the condensers CA, CB are set to different values so that the section E is asymmetrical. For long lead-in cables (up to 330 ft.) a fixed section G adapted to the impedance of the open-wire line OL is added between the cable LC and the line OL, and a fixed shunt condenser C'A may be added to the section E. The section E may be provided with calibrated dials.
