Filed: 1926-07-31
Abstract: 274,285. Whiting, R. O. July 31, 1926. Multiple-movement apparatus.-Apparatus for indicating average speed comprises a disc 8 which is rotated through an angle proportional to the logarithm of the distance travelled, and a disc 9 which is mounted upon the first disc to rotate with it, but is at the same time independently rotated reversely through an angle proportional to the logarithm of the time. The resultant movement of the disc 9 relative to the fixed casing 1 is proportional to the logarithm of the quotient, and a scale of average speeds may be provided on the disc to be read against a fixed pointer. Automatic mechanism is provided to reduce the speed ratio of each disc by ten to one after each complete revolution. In the arrangement shown in Figs. 1 and 3, a shaft 2 driven by a road wheel of the vehicle rotates the disc 8 through worm 6, gear, 10, reducing gears 11 - - 16, change speed mechanism 18 - - 26, and a long pinion 28 which meshes with a logarithmic rack 29 on the under side of the disc. The automatic change speed device comprises a slotted cylinder 47, Fig. 5, the slot of which is engaged by a. pin 50 carried by a loosely mounted sleeve 49. Two pins 52 carried by the double gear 25, 26 embrace the pin 50 and cause it to travel round the slot. After one revolution corresponding to ten miles, the pin is moved sideways by the slot and shifts the gear 25 axially to mesh with the pinion 19 to give the reduced speed for the second revolution. The speed ratio is again reduced after the second revolution corresponding to 100 miles, for the third revolution, at the end of which the gear 25 is pushed into the space between the gears 20, 21 and the device ceases to function. The upper spindle 3 is connected to the vehicle driven spindle by a friction clutch 4, 5 and its speed is kept constant by an escapement (not shown). It rotates the upper disc 9 through worm 7, reducing gears 30, 31, change speed mechanism 33 - - 40, and a long pinion 43 which meshes with a logarithmic rack 44 on the under side of the disc. The automatic change speed mechanism which operates at the completion of each revolution of the disc 9 is similar to that provided for the disc 8. The change preferably takes place at one end of 30, 300, and 3000 minutes respectiviely. The time mechanism stops when the vehicle stops. Knobs 53, 58 are provided for resetting the mechanism.

Title: Improvements in and relating to preserving perishables such as fruits, vegetables and the like in their natural condition
IPC: A23B7/148
Filed: 1932-07-07
Abstract: 395,508. Preserving fruit, vegetables, &c. UNITED FRUIT CO., 1, Federal Street, Boston, U.S.A. July 7, 1932, No. 19282. Convention date, April 8. [Class 49.] In preserving perishable materials such as fruit, vegetables, &c., in natural fresh condition by passing cooling air over them, drying of the materials is prevented by depositing a film of moisture on the surface of the materials, e.g. by spraying fresh water thereon, whereby a source of moisture is made available to the circulating air. In the construction described, the perishables, e.g. bananas, are disposed in a ship's hold A, Fig. 1, to which water is supplied as a spray from nozzles 20. The water is fed to a tank 22 from a supply pipe 21 controlled bv a ball float valve 23 and is forced from tank 22 by a pump 25 through pipe 24, strainers 30, pipe 26, valve 32 and pipes 34 .. 37 to the nozzles 20, the pipe 37 being connected as a return to the tank 22. Compressed air is supplied to the nozzles 20 from a compressor 50, through a purifier 53, which removes oil particles, a valve 56<1> and pipes 54 .. 57. Each nozzle 20 comprises a casing 60 having threaded portions 61, 62 for connection to the air and water pipes. The water enters, through bores 70, 71 and a narrow orifice 73, an annular chamber 76 formed between the casing 60 and a cap 75 screwed thereon and communicating with a chamber 78 having a recessed portion 79 from which extends radially four spray apertures 81. Compressed air is supplied to the chamber 78 through bores 67, 65 and an orifice 63. The bores 65, 71 are closed at their upper ends by removable plugs 64, 72. The amount of water supplied to the hold may be reduced by increasing the supply of compressed air to the nozzles 20 by opening the valve 56<1>. After the fruit has been moistened, cooled air is supplied to the hold through side ducts 13, Fig. 1, which enclose deflector members which curve down in a longitudinal direction to direct the air to various parts of the bottom whence it passes upwardly through the floor grating 14. The air is drawn from the hold A by fans 10 which force it through refrigerating coils 12 to the ducts 13. Water is precipitated from the moist air on the coils 12 and is conducted by draining devices 40, Fig. 5, to the pipe 41 which conducts it, with the water draining from the hold through drains 43, to the tank 22. The air is introduced into the hold at a comparatively high velocity to reduce quickly the initial high temperature of the fruit and the spray water can be cut down. When the desired low temperature is reached the air supply and the water spray can be diminished.

Abstract: 194,635. Haddan, A. J. H., (National Cash Register Co.). Oct. 4, 1921. Line - spicing mechanism ; web-feeding arrangements.- In a machine wherein the items, date, &c. an printed upon a record strip means are provided for shifting the strip so as to bring the last imprint from the printing line tea point adjacent a writing slot to enable autographic entries to be made below the imprint and at the next operation of the machine, the strip is shifted back again before printing, line - spacing manually variable in extent being then imposed before impression occurs. The record-strip 348 passes from a spool 349 around rollers 352, 354, over a roller 357 beneath a platen 362 over guide bars 363, 364, along a writing plate 375 to a roller 366 and thence around roller 367 to the receiving- spool 370. The platen and writing-plate are mounted between the arms of a frame. 360 pivoted at 358 and the plate is situated below a slot in a transparent sheet covering the last few entries on the record-strip. The rollers 354, 367 are carried by a lever 356 which by means of cam mechanism is rocked during the operation of the machine, first counter-clockwise so as to bring the next line on the strip from the writing-plate to the printing position and then, after impression has been effected clock-wise to bring the space immediately succeeding the imprint, into register with the writing slot. Between these two movements of the strip and prior to the printing operation the strip is fed forward for line-spacing by means of a friction pawl lever 383 rocked by a cam to rotate the receiving-spool to the necessary degree. The amount of this feed may be varied by shifting a hand-lever 405 so as to cause a stop-pin carried by an arm 396 to limit more or less the forward non-feeding travel of the pawl lever 383. Reference has been directed by the Comptroller to Specification 157,824.

Abstract: 910,390. Moving coil instruments. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 11, 1959 [June 14, 1958], No. 20045/59. Class 40 (4). A coil stuck by one of its faces on to a diaphragm, comprises a plurality of layers, each comprising a plurality of substantially plane windings (the transition from a winding in one plane to a winding in the next taking place over a small angular distance), the ends of the coil being adjacent the diaphragm and being formed by windings of the two outermost layers, the outermost of these windings 18, Fig. 3, not forming a complete turn, the space α not being used by this latter turn being used to accommodate the extended end 21 of the other turn which is bent back on itself. By this means the coil presents a substantially flat face to the diaphragm to facilitate its sticking thereto. The angle α is preferably made equal to 180 degrees so that the connections 23, 21<SP>1</SP> load the diaphragm symmetrically. As shown, Fig. 1a, the wire is drawn through a slot 5 in a flange 3 of the winding mandrel 1 and led by a finger (not shown) moved step-wise at position 11 to produce plane windings for the inner coil. When sufficient windings have been put on, the flange 9 is fixed into position, Fig. 1b and the wire now moves into the position of the outer coil in the recess 15. After a length α of this turn has been completed the wire rises on to the shoulder 13 and then continues to complete the outer coil, the operation terminating at position 11, to allow room for the bent-back part of the beginning of the coil which is now removed from the slot 5 for this purpose. The coil may consist of more than two layers, Fig. 4 (not shown).
