Title: Improvements in machines for cleaning beetroots and tubers
IPC: A23N12/00
Filed: 1926-02-22
Abstract: 270,835. Brochet, F. Feb. 22, 1926. Cleaning and peeling beetroots and tubers.- Machines for cleaning beetroots and tubers comprise rotating cylinders each constructed of longitudinal bars 4 mounted on discs 2 and carrying a helical line of points 5 adapted to scrape and forward the roots placed in contact with them. A pair of cylinders of different sizes may be used, the cylinders lying side by side and rotating in the same direction. Alternative arrangements comprise (1) a duplicated and symmetrical form of the above arrangement, (2) three cylinders side by side, one of the outer rollers being larger than the others, (3) a single cylinder of large diameter which may if desired be conical, the roots being delivered on to the smaller or the larger end according to the nature of the soil from which they are taken. The line of points 5 in the last construction may be interrupted in the centre of the cylinder and replaced by a circularly arranged points to increase the duration of the cleaning action. In a modified construction the cylinders are replaced by an endless metal band, mounted on a pair of rollers of different diameters, and provided with an oblique line of points.

Title: Improvements in liquid actuated friction clutches
IPC: F16D43/284
Filed: 1945-03-01
Abstract: 594,790. Friction clutches. MERCURY CLUTCH CORPORATION. March 1, 1945, No. 5155. Convention date, Feb. 24, 1944. [Class 80(ii)] In a friction clutch of the kind in which segmental shoes 27, carried in a chamber 16 secured to a driving shaft 3, are moved radially inwards into frictional engagement with a drum 21 on the driven shaft 4, by centrifugal pressure of a liquid, such as mercury, of greater specific gravity than the shoes, and carried in the rotating driving chamber 16, the chamber 16 is automatically drained to a fixed reservoir 42 below a predetermined speed, to disengage the clutch, by a centrifugally-loaded valve 38 carried by the driving chamber 16 and opened by a spring 39 below the required speed. To re-engage the clutch, the chamber 16 is filled from the reservoir 42, through a pipe 48, by a piston 43, diaphragm, or centrifugal pump, operated by a handle 45, or solenoid. The piston may be arranged vertically and have clearance in its housing so as to operate by displacing liquid vertically upwards past its face, Fig. 3 (not shown). The adjacent ends of the segmental friction shoes 27 are spaced in the driving casing 16 by abutments 18 and are recessed for expanding take-off springs 28. In Fig. 5, the centrifugal-valve 38 can also be controlled manually by a three-position cam 70b which is slidable axially in the driving shaft 3 under control of a manual lever acting through a thrust collar. In the first position, shown, free centrifugal closure and spring-opening of the valve 38, as in Fig. 1, are possible. In the second position of the cam a hump 81 overlies the end of the valve-stem to maintain the latter closed at all speeds thus preventing clutch disengagement under valve action. In the third position of the cam a fork 83 rides under and raises the head of the valve 38 to maintain the latter open at all speeds, thus disengaging the clutch. In Fig. 4 (not shown), the cam is a simple cone giving only positions 1 and 2 above. Specifications 558,546 and 559,778 and U.S.A. Specifications 1,972,741, 2,258,157, 2,283,267 and 2,307,797 are referred to.

Abstract: An article having a contoured surface is spray coated by electrostatic deposition of the coating material from a spray by means in which the article or its associated support comprises a collecting electrode and there is provided a spaced discharge electrode, said electrodes inducing an electrostatic field of high potential difference, and the discharge electrode being generally conformed in shape or arrangement to the contoured surface of the article.  A cylindrical article 10, Fig. 1, is conveyed through a spraying zone, into which a coating is sprayed from guns 11, by means of hangers 12 drawn by chains 13 along track 14.  Partially surrounding the line of travel of the articles is a discharge electrode 15 mounted on insulating legs 16 and between the supports 15 are longitudinally extending wires 17 connected to one terminal of a high voltage source 18.  The other terminal is earthed and so is the track and the article.  Thus an electrostatic field is produced by the electrode wires 17 and the articles.  The coating material is sprayed into this field and the particles are electrically attracted on to the article.  In the modification of Fig. 2 there are shown spray nozzles 111, discharge electrode 117, belt type conveyer 113 <PICT:0594564/III/1> <PICT:0594564/III/2> <PICT:0594564/III/3> <PICT:0594564/III/4> and carved articles 110.
