Title: Improved apparatus for cracking, dividing and otherwise treating nuts and the like
IPC: A23N5/00
Filed: 1923-08-29
Abstract: 213,500. Benedetto, A., and Cox, O. A. Aug. 29, 1923. Cracking nuts; crushers with vibrating jaws. - Apparatus for cracking, dividing, and otherwise treating nuts &c. comprises two or more rotary jaw-carriers with the jaws disposed in pairs opposed to each other, means to feed the nuts &c. successively between pairs of jaws, and means gradually to close the space between the jaws. The shaft 4 carries rotary cylindrical jaw - carriers 5, 6, 7. The central plate-like carrier 6 has a number of rigid jaws 8 with radially-arranged cutter - blades, while the outside carriers 5, 7 are coupled together by rods 15 passing through the carriers 6 and have detachable jaws 9 carried at the ends of plungers 10 which reciprocate in recesses 11 in the carriers. Rollers 14 at the ends of the plungers run on an inclined track 20 secured to a fixed disc 18. The track 20 has a gradual rise 21 and a sudden declivity 22; and the jaws 9 are advanced against the action of springs 16 which abut against the central carrier 6 at one end and against lugs 17 on the jaws 9 at the other end. The nuts pass from a container 24 down an inclined runway 25 on to an adjustable feeding- device 26. A bracket 29 for each pair of jaws is mounted on the carrier and supports a gripper comprising a back 31 which moves between the parallel frames of the feeder 26 and carries the nut up the curved end 30 of the feeder. The end 30 is eccentric to the travel of the gripper so that the nut is lowered on to the bottom springy finger 32 between the side prongs 3 which lie outside the two frames of the feeder and engage the nut near its ends. A jaw-cleaning device to remove any pieces of nut jammed into the jaw comprises a framework 35 carrying blades 34 which are spaced so as to just close the jaws 8, 9 when in their lowest position. A spring- controlled trip-roller 39 prevents the nuts from piling up on the feeder 26 and ensures that only one nut at a time is carried up the curved end 30. The cam tracks 20 may be undulating so as to impart to the jaws a series of progressive crackings. The cracked nuts fall on to a conveyer band 36. Instead of one fixed and one, reciprocating jaw, both jaws may reciprocate.

Abstract: 1,113,108. Abrading. CORNING GLASS WORKS. 24 May, 1965 [1 June, 1964], No. 21874/65. Heading B3D. A method for finishing a contoured surface of a frangible article, such as a TV panel, comprises rotating the article 65 to be finished about an axis perpendicular to a tangent centrally contacting the contour of the surface to be finished, and moving a contoured continuous work surface 26 over the rotating surface to be finished. The work surface may be in the form of a solid contoured rim or a plurality of liners of flexible material, such as neoprene, neoprene and cork or sizal, woven fabrics and rubber, felt on rubber, coated abrasives including diamondcoated mesh, or walrus hide, secured to the inner surface of a contoured rim 24 of a drum 23 mounted on a spindle 20 rotated by a belt drive 34, 37 from a variable-speed electric motor 33, the contour of the rim having a radius substantially equal to the radius of the drum. The article 65 is mounted on a workholder 64 supported by a shaft 63 connected by a rightangle drive unit 62 to a shaft 60 which is rotatable by a belt drive 57 from a motor 55 and is located at one end of a guide arm 58 rockable about a shaft 46 by a piston-and-cylinder device 69 connected by universal joints 67, 73 to the frame of the machine and the guide arm. The motor 55 and guide arm are mounted on a platform which is movable along the shaft 46 by a piston-and-cylinder device from an operating position, in which the article can be engaged with the work surface 26, to an inoperative position (indicated by dotted lines) in which the article can be mounted on the work holder 64. Pumicing or polishing slurry is supplied from a tank by a pump through a pipe to the interior of the drum and can pass through a slit 25 or other drainage openings in the drum into an outer shell 27 having a drainage opening leading to the tank, a mixer maintaining the slurry homogeneous. In another embodiment, the machine has three rotating workholders disposed within the rotating drum and indexable to bring the workholders successively to an unloading station wherein the tables can be retracted by piston-bellows arrangements and moved outwardly along slides. In a further embodiment, the rotatable work-holders are disposed within a frusto-hemispherical member and are mounted on a table which is indexable to bring the work-holders successively to an unloading position wherein they are slid inwardly along tracks.

Filed: 1976-08-17
Abstract: 1508002 Boring earth etc. CEMENTATION RESEARCH Ltd 17 Aug 1976 [21 May 1975] 22002/75 Heading E1F An elongate member G, such as a core sampling tube, or a tube containing measuring instruments, is driven into or extracted from the sea bed by means which grip and move the tube G, the gripping and moving means being mounted on a chamber J which is watertight apart from a porous surface Z in contact with the sea bed, water being sucked from the chamber whenever the gripping means is moved towards the sea bed to provide a reaction for the force exerted by the gripping means. The means for moving the tube G may be a conventional rotary or vibration drive (not shown) or may be an arrangement for thrusting the tube G into the sea bed. In a first embodiment (Fig. 1) the apparatus includes a cylindrical chamber J which is divided by an internal wall P into a lower reaction chamber having the porous surface Z and an upper drive chamber whose upper wall H is connected to the cylindrical wall J by a bellows F or telescoping device (not shown). The cylinder J is also provided with a skirt K which penetrates the sea bed. The tube G passes through a guide L mounted on members M and through clamps E, R in the walls H, P respectively, which seal against the tube G and which are capable of selectively gripping the tube G. The drive chamber has ports A, D with valves B, C; the reaction chamber has a port with valve S; and a port with valve N is provided in the wall P. In use the tube is driven into or extracted from the sea bed by operating clamp E and pumping water out of or into the drive chamber, thereby creating a differential pressure across wall H which causes it to move downwardly or upwardly. When moving downwardly water is pumped out of the reaction chamber, either through valve S or by opening valve N. In a second embodiment (Fig. 6) the tube G passes through a casing O in the cylinder J. The upper wall H of the drive chamber is formed as a piston and carries tube clamp E. The device operates as in the first embodiment. In a third embodiment (not shown) three reaction chambers and drive chambers are provided and are arranged at the corners of a triangle, the tube G being located at the centre of the triangle. In a fourth embodiment (not shown) the drive chambers are replaced by hydraulic jacks.

[Class 29] Compression machines.-In a totally enclosed refrigerating machine comprising a driving motor 4, gearing 5, compressor 6 and condenser 2 disposed within the refrigerating medium space enclosed by a casing 1, the oil in the lubricating system of the machine circulated by a pump 7 is cooled in a cooler 8 by condensate trickling from an auxiliary condenser 9 also disposed within the vapour space and above the cooler 8. The lubricant is stated to be always kept warmer than the vapour surrounding it thus preventing condensation of the vapour on the lubricated parts and consequent dilution of the lubricants. The auxiliary condenser may be cooled by water tapped from the supply pipe of the main condenser. The cooling condensate may be collected in vessels 11 and 12 and conveyed therefrom to other parts to be cooled, such as the gear casing and bearing casing.
