Title: Mechanism for removing the rind from pineapples
IPC: A23N4/20
Filed: 1953-03-31
Abstract: 724,331. Endless and pneumatic conveyers. FOOD MACHINERY & CHEMICAL CORPORATION. March 31, 1953 [July 29, 1952], No. 8866/53. Class 78 (1). [Also in Group VI] Pineapples are pushed against the sharp edge 35a of a rotated tube to separate from the rind the edible core which passes into the tube and is ultimately blown out of the other end of the tube by compressed air admitted between that core and the core of the succeeding pineapple. Each pineapple placed in a bottom slotted trough 77, Fig. 8, is pushed against the knife by a pusher 69 on conveyer chains 61, the pusher being controlled by fixed cams to move the pineapple through spring centring fingers 80 into the tube 35, each pusher then tilting backwards to clear the tube on the conveyer chains round the sprocket 63. Compressed air from a manifold 48 enters the annular chamber between the extension of the tube 35 and the surrounding tube 30<SP>11</SP> and exits through holes 46a into the space between successive pineapple cores to force the cores out at the left hand end of the tube. As the fruit is blown along other air supply holes 46b &c. are uncovered to continue the delivery. The tubular cutter assembly comprising extensions of the inner and outer tubes is mounted within ball races 50a and 50b in the sides of the manifold 48 and is rotated by a belt pulley 20 from an electric motor. Slots 47 in the tubular jacket 30 allow compressed air from 48 to pass into the space between the tubes. A juice shield 45 is also provided on 30. The annular rind moving on to the tube 35 may be cut by a radial knife, not shown, so that it can fall away. Each core fruit is blown from the tube 25, Fig. 3, into one or other of receiving tubes 95, Fig. 5, mounted on a turret disc 91, rotated step-by-step in synchronism with the fruit core delivery and strikes against a buffer. 99 with air cushioning effect determined by the distance that the buffer 99 is spaced from the tube 95, whereby escape of air in front of the fruit core takes place between the buffer 99 and its tube 95. An adjustable collar band 102 is also provided to regulate the air escape between tubes 25-28 and 95. The fruit in the tubes 95 may be trimmed at each end by known stationary knives 120, 121 and the small hard core may also be removed in known manner. The fruit is then ejected by any suitable means into an inclined discharge trough (D, Fig. 2, not shown).

Title: Improvement in pneumatic comparator gages
IPC: G01B13/10
Filed: 1944-05-11
Abstract: 577,921. Gauging-apparatus. MOORE, C. B. May 11, 1944, No. 8996. 'Convention date, July 2, 1943. [Class 106 (ii)] A pneumatic comparator gauge comprises a body member 11 having a fluid space 18 therein, means 12 for supplying fluid to the space, means 22 for controlling discharge from the space in accordance with the dimensions of the work to be gauged, means 38 for indicating the pressure in the space 18 and cushioning means 29 interposed between the indicating means and the fluid space. Filtered air at constant pressure enters a passage 12 and passes through a pressure-reducing nozzle 17 to a space 18 which communicates with nozzles 22 in the gauging member 20. The increase in pressure in the space 18 caused when the air flow through nozzles 22 is restricted by the surface being gauged lifts a diaphragm 29, thereby operating the pressure gauge 36 through the medium of a fluid above the diaphragm. When the gauging member 20 is withdrawn from the work-piece, the air pressure in space 18 drops and the centre of the diaphragm 29 again covers the end of the passage 30. A cushioning effect is produced by air trapped in an annular groove 32, this air escaping slowly, however, through a radial slot 33.

Title: Improvements in centrifugal friction clutches
IPC: F16D43/18
Filed: 1925-04-08
Abstract: 245,323. Brown & Sons (Huddersfield), Ltd., D., and Merritt, H. E. April 8, 1925. Clutches, friction. - In centrifugal clutches comprising shoes carried in peripheral recesses in a driving-spider and coacting with a driven spider, the contact between the shoe and spider is such that the shoe, as it wears, turns about a virtual centre which lies in a line substantially at right angles to the radius through the centre of the shoe, and at a finite distance from the clutch axis. The distance of the virtual centre from the clutch axis determines the amount by which centrifugal force is augmented by a radial component of the driving-thrust on the shoe. As shown in Fig. 1, the driving-face b<1> of the spider a and coacting face c<1> of the shoe c are portions of a sphere centred at e in the line f-g. These surfaces may, however, be cylindrical and may, further, be interrupted. An interrupted cylindrical surface on the shoe may have two or more line contacts with surfaces of smaller radius on the spider, or an interrupted cylindrical surface on the spider may have line contacts with curved or plane surfaces on the shoe, the axis of the cylindrical surface in either case essentially intersecting the line f-g. Fig. 4 shows a form in which the drive is divided between pairs of faces b<2>, c<2> and b<3>, c<3> struck from the common axis e. In another modification, these pairs of surfaces are both on the same side of the axis of symmetry f-h of the shoe c. Another arrangement is described in which the drive is similarly divided between three pairs of surfaces. Faces b<1x>, c<1x>, Fig. 1, and b<2x>, c<2x>, b<3x>, c<3x>, Fig. 4, are provided for reverse drive.
