Title: Apparatus for dispensing measured quantities of substances in powder form
IPC: B65G65/48
Filed: 1963-08-14
Abstract: 1,037,310. Delivering measured quantities of granular material. W. PECHMANN. Aug. 14, 1963 [Aug. 16, 1962], No. 32115/63. Heading B8N. Apparatus for dispensing measured quantities of powder comprises a rotary member 10 having a line of measuring chambers 15a opening on to the periphery of the member and adapted to be connected to vacuum and pressure sources for filling. and emptying the chambers respectively, the member being formed with a sector-shaped cut-out 11. The chambers 15a are connected by a duct 18a which extends through an endplate 20 of the member 10 and is coupled, via a semi-circular groove 22a in a non-rotatable plate 21 urged by a spring into sealing contact with the plate 20, with a source of vacuum. A second row of measuring chambers 15b is formed in the rotary member and connected by a duct 18b which communicates, via a port 28 and pipe 29, with a source of air pressure. In operation, with the rotary member in the position shown, a vacuum is applied to the duct 18a thereby drawing powder from a hopper 12 into the chambers 15a. At the same time the powder in the lower chambers 15b is dispensed by feeding pressurized air to the duct 18b. The rotary member is then rotated, by means of a hand wheel 13 or a geared motor, in the direction of arrow 30, the duet 18a being in communication with the groove 22a thereby preventing the powder in the chambers 15a from falling out during their downward movement; the chambers 15b rise to the filling position and upon application of the vacuum and pressure, dispensing and filling is repeated. A second semi-circular groove 22b is formed in the plate 21 so that when the rotary member is reversed in the opposite direction, the powder in the chambers 15b is retained therein. In a modification, several rows of chambers are formed in each side of the cutout 11. The inner ends of the measuring chambers are closed by means of steel brushes 16, 17, Fig. 1, the brushes being adjustable in order to vary the capacity of the chambers.

In a magnetic recording apparatus the record tape 6 is carried on spools 3, 4 in a box 5 from which the tape 6 extends in a loop so that it may easily be inserted between a part 7 carrying a guide wheel 11 and feed roller 10, and another part 8 containing the transducer 9 and pressure roller 10. In one embodiment, Figs. 1 and 2, the transducer 9 and pressure roller- 10 are mounted on an arm 14 which is moved. during a recording operation to bring the transducer 9 into a position in which it presses the tape 6 against a spring-loaded support 16 carrying the guide wheel 11, and the pressure roller 10 presses the tape 6 against the feed roller 12. The support 16 carries an electrical contact arm 18 which breaks contact with a member 20 to stop the apparatus when excess tension occurs, such as may occur when the end of the tape is reached and the tape is attached to its spool. the movement of arm 14 may be controlled by a flexible cable control. The transducer 14 and pressure roller 10 may also be mounted on separate arms and separately controlled, so that the pressure roller 10 may be withdrawn, thereby interrupting the drive and leaving the transducer pressed against the tape, as may be required in a dictation machine.
