Title: Process for obtaining tamarind seed jelose
IPC: A23L29/238
Filed: 1964-08-14
Abstract: In a process for obtaining tamarind seed jellose from an aqueous extract obtained by treating seeds of Tamarindus indica Linn. with hot water, one or more of sodium sulphate, ammonium sulphate, magnesium sulphate and aluminium sulphate is added to the extract, thereby coagulating the jellose, the resulting coagulate is separated, and jellose is recovered therefrom.  The aqueous extract of jellose may be obtained by blowing steam into an aqueous dispersion of ground, bleached seeds.  The sulphate may be added in solid form or as a concentrated aqueous solution, to the aqueous extract at 70 DEG  C.  The coagulated jellose may be separated by sieving, and occluded salt is preferably removed from the coagulate by washing with an aqueous lower aliphatic alcohol, e.g. ethanol alcohol concentration 20-40% by weight.  The salt-free coagulate may be centrifuged and dried.

Title: Rotary intermittent gear
IPC: F16H27/06
Filed: 1946-11-11
Abstract: 630,144. Intermittent toothed gearing. SCHWEIZ INDUSTRIE-GES., and LUGINBUHL, P. Nov. 11, 1946, No. 33476. [Class 80 (i)] An intermittent drive is obtained from a continuously rotating driving shaft 1 which is geared through a double gear 6 with a planet pinion 10 rotatably mounted on a carrier arm 14 secured to the driven shaft 22. On one end of the planet spindle 12 is a pin arm 16 of a Geneva mechanism, the co-operating wheel 19 of which is secured to a fixed part 20. The spindle 12 also carries a locking disc 18 adapted to co-operate with arcuate recesses 21 on the periphery of the wheel'19 but having a gap defined by shoulders 27, 29. The arrangement is such that the pin arm 16 and disc 18 is rotated by the shaft 1, whilst the disc 18 is in locking engagement with the wheel 19, without imparting movement to the carrier arm 14 on the driven shaft 22. On the pin 17 of the arm 16 engaging in one of the slots 28 of the wheel 19 the gap 27-29 of the disc 18 unlocks its engagement with the wheel and the carrier arm 14 rotates by reason of the engagement of pin 17 in the fixed slot of the Geneva wheel. This movement continues until the pin 17 disengages again and the disc 18 then locks into the next recess 21 of wheel 19. In a modified arrangement the Geneva wheel is secured to the planet spindle and the pin arm of the mechanism is fixed. In this case also the planet carrier arm is the driving member and a sun gear co-axial therewith is driven. In this arrangement when the Geneva mechanism is locked the carrier arm drives the sun gear direct but on engagement between the Geneva wheel and the fixed pin arm the rotation of the planet gear prevents rotation of the sun gear.

[Class 78 (i).] A conveyer for lump or granular material comprises a sectional framework in which is mounted an endless chain or belt having on one side of it a plurality of blades, which conduct the material on to the chain or belt. The conveyer is simultaneously moved towards or away from the material by projections on the chain or belt engaging sprockets which rotate screws, mounted on the framework, in stationary nuts. As shown, the chain b, Fig. 1, passing over power-driven tumblers f having driving-pieces g, is provided with blades c, d, Fig. 3, which conduct the material on to the chain to convey it to a discharge aperture y. Big lumps which do not fall through the aperture are removed by a plate z. Projections on the chain engage sprockets k on spindles k<1>, Fig. 13, to which are keyed pinions p meshing with pinions q, fixed on screws m mounted on the conveyer framework. These screws are mounted in nuts n, held rigidly in position by brackets o, so that as the screws rotate they move the framework towards the material. To reverse this movement handles x, Fig. 8, are operated to engage pinions p<1> with the pinions q, pinions p becoming disengaged. In a modification, Fig. 16, this lateral movement of the conveyer is obtained by mounting the framework on wheels A, driven by a bevel wheel B keyed to k<1> and meshing with one of wheels D, D<1>. These wheels are mounted on a shaft H with a clutch G between them, the shaft H being at 90‹ to the spindle k<1> and .connected to the wheels A by reduction gearing. The bevel wheel B may be replaced by worm gearing. The sections of the conveyer framework are connected by knuckle joints but may be rigidly connected. The blades may be adjusted so that the chain can be rotated in a reverse direction.

[Class 146 (ii).] A device for illustrating the real and apparent movements of the celestial bodies comprises a glass or celluloid sphere 1, Fig. 1, representing the heavens, rotatable on an axis 8, 10 and carrying mechanism for effecting the rotation of the representations of the planets. The sphere is rotated by a handle 5, and the internal mechanism is rotated relatively thereto by a handle 37. If the sphere be rotated and the handle 37 be held from rotation, a gear-wheel 15, inclined at 23¢‹ to the axis 8, 10, is caused to roll round a gear-wheel 16 and rotate, through a gear-wheel 19, a gear-wheel 20 to which is attached a carrier 21 for a representation of the sun, and a carrier 26 for the earth's shadow. The relative movements of the sun and sphere indicate the variations in height of the sun above the horizon during a year. The wheel 20 is connected to an internally-toothed wheel 24, which by means of gear-wheels 32, 33, 29 effects the timed rotation at the correct inclination of the moon-indicator 30. In order to indicate the movements of the planets relatively to the sun, the gear-wheel 27 is caused to mesh with the gear-wheel 15 so as to drive directly the shaft of the gearwheel 24, Figs. 4 and 4<a>. The wheel 24 is disconnected from the wheel 20 and is raised to permit the insertion of carriers 35, 36 for the representations of Jupiter and Mars connected to gear-wheels 351, 361 driven by gear-wheels 18, 17 on the shaft of the gear-wheel 15. The gear-wheel 29 is moved to the position shown in Fig. 4<a> and carries, on its axis, a representation of the earth and, slightly spaced from the axis, a representation of the moon. The gear-wheel 33 carries a representation of Mercury, and a pulley 42, loose on the shaft of the gear-wheel 33 and driven from a pulley on the shaft of the gear-wheel 32 carries a representation of Venus. The carrier 21 is employed to represent Saturn. By changing the positions of the gearwheels and pulleys, the movements according to the Copernican, Ptolemaic, and Tycho de Brahe systems can be illustrated.

Abstract: 467,414. Drilling. JONES & SHIPMAN, Ltd., A. A., and WILKINSON, J. H. Dec. 12, 1935, No. 34504. [Class 83 (iii)] In a rotatably adjustable depth stop device for a drilling or like machine where one part is secured to the usual cross-axle or feed shaft, and another part carrying a stop member is adapted to be adjustably locked to the first part and in a predetermined position with respect to an abutment on the machine, the device is characterized in that the locking arrangement consists of a ratchet mechanism. The part 6, Fig. 4, keyed to the pinion feed shaft of the machine, is connected to an adjacent part 7 carrying a stop pin 8 by a releasable ratchet device, the pawl 9 for which is adapted to be raised out of mesh with teeth on the member 6 by rotation of a rotatable setting member 12 provided with handles 15. In one direction of movement of the member 12, the pawl slips over the ratchet teeth against the effect of a spring 11, but in the opposite direction of travel the pawl is rotated by a pin 14 engaging the tailpiece 10 integral with the pawl until the pawl is free of the ratchet teeth. A pin 13 in the setting member then engages, after an amount of lost-motion necessary to raise the pawl, with the side of an opening 7c in the plate 7 to rotate this and thereby set the stop 8 relative to the abutment 21a provided in the casing 19. This casing may be capable of limited rotary adjustment by a screw 22a engaging a fixed abutment 23, Fig. 3. Indications viewed through a window 19e in the casing show the depth of the setting. A micrometer 30 may be substituted for the stop 21 to provide for further accurate adjustment, and in a modification ratchet mechanism of the friction type comprising balls or rollers held by springs and. adapted to be wedged between the two parts of the locking device, may replace the pawl and toothed disc.
