IPC: G01G13/00
Abstract: 133,801. Avery, W. & T., and Parnall, T. St. J. B. Oct. 30, 1918. Automatic - feed weighers. - In automatic or semi-automatic weighing-apparatus provided with shaker feed supply mechanism operated by power-controlled means synchronized with the operations of the weighing - apparatus, the feed supply mechanism being prevented from restarting until the weigh-hopper discharge door is closed, the synchronizing mechanism comprises a cam on a power driven spindle operating a clutch lever so that the reciprocation of the feed plate ceases at a predetermined point. The discharge door is provided with locking means which, when the door is open, holds the clutch device in its disengaged position. These modifications are applicable to the weighing-apparatus described in Specifications 4935/05, 13544/06, 15690/09 and 103,707. As shown, the feed hopper 4, Fig. 1, is provided with a horizontal reciprocating feed-plate 5 the movement of which discharges the coal, coke, ore, potatoes, or other material through an adjustable lateral opening 6 into the weigh hopper 7. The feed-plate is reciprocated through a rod 8 and a crank-disk 9 rotated through a spur and pinion from a shaft 35, Fig. 2. in clutch connexion with a driven shaft 10, the shaft 10 being in clutch connexion with the operating mechanism of the weighing-apparatus. The clutch connecting the shafts 10, 35 is adapted to be engaged and disengaged by a spring and by levers 13, 15, the latter of which carries a roller engaging a cam driven from the mechanism controlling the traverse of the poise weight. An arm 22 mounted on the cam spindle serves to break the toggle-joint locking mechanism of the discharge door. A rod 14 connecting the levers 13, 15 carries a roller 25 which is normally in the path of a pivotally mounted segment 26 forming part of the discharge door locking mechanism. When the clutch is disengaged, the roller is moved out of the path of the segment, and the discharge door is free to be opened on the next motion of the arm 22 to break the locking mechanism. The segment then assumes a position which prevents the roller 25 from returning, and consequently prevents the clutch from re-engaging and the feed from restarting until the discharge door is again closed.

Title: Improved process for inhibiting the formation of undesirable colour in animal or vegetable oils or fats and the oils or fats produced thereby
IPC: C11B5/00
Filed: 1932-08-18
Abstract: Discolouring of animal or vegetable oils or fats on exposure to air and light is prevented by incorporating not more than 0,05 per cent of colloidal copper, cobalt, cadmium or silver, or of carbonate of cobalt, copper, lithium, manganese, cadmium, barium, bismuth, nitrate of calcium, beryllium, lithium, acetate of sodium, copper, manganese, hydrate of cobalt, beryllium, copper, thorium, or of a mixture of cobaltous carbonate and copper carbonate with or without bismuth subcarbonate.  Usually 0,00025--0,00050 per cent is used, determined to give the same weight of metal as is contained in the proportion of copper carbonate not colouring the oil or fat green but sufficient to enable the oil to transmit white light substantially without selection of the different frequencies.  Lard cottonseed, china wood and linseed oils are specified for treatment.  The Specification as open to inspection under Sect. 91 describes the treatment of natural oils or fats with up to 0,05 per cent of a metal or metallic salt. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in automatic clutches for power transmission systems
IPC: F16D45/00
Filed: 1947-05-20
Abstract: 626,788. One-way clutches; friction clutches. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and WATSON, K. May 20, 1947, No. 13545. [Class 80 (ii)] A friction clutch is arranged in parallel with a one-way clutch, the latter having speed responsive engaging means, and a second one-way clutch is arranged in series with the friction clutch to permit overrunning of the driven member. In a drive for a helicopter rotor a driving member 6 carries fixed and sliding friction clutch plates 7, 8 respectively, the plate 8 being moved by centrifugal weights 18, above a speed determined by an opposing spring 20, to engage a driven clutch plate 9. The plate 9 is rigid with a sleeve 10 forming the outer member of a jamming roller clutch whose rollers 13 are carried in a cage 14 biassed in the direction of rotation by springs 16 anchored to the driven shaft 12. The driving member 6 is also formed at 21 as the outer race of a jamming roller clutch having rollers 23 carried in a cage 24 of which extending lugs 28 are engaged by a weighted lever 26. Centrifugal force on the weight of the lever engages this clutch when sufficient to overcome the opposing force of a spring. In operation the friction clutch is engaged at a relatively low speed by the weights 18 and drives through the one-way clutch 10, 13 until at a relatively high speed the one-way clutch 21, 23 engages to take the torque over and above that transmitted by the friction clutch. In a modification the rockers 19 carrying the weights 18 may be locked in the inoperative position by spring loaded trip levers carried by the driving member 6 and engageable by a displaceable roller mounted in the clutch housing to trip the levers and release the weights. This modification may be interconnected to a brake holding the driven shaft so that simultanous engagement of clutch and brake is prevented.

Filed: 1935-05-13
Abstract: 456,737. Force - feed lubricating. LUCAS, Ltd., J., Great King Street, Birming- ham.-(Bijur Lubricating Corporation; 22, 43rd Avenue, Long Island City, New York, U.S.A.) May 13, 1935, No. 13955. [Class 12 (iii] In a lubricating system, lubricant is pumped intermittently into and discharged from an accumulator, the admission and discharge of the lubricant from the accumulator being controlled by one or more spring-urged valves actuated once during each revolution of a member which is driven through reduction gearing from a rotary driving member. As applied to an automobile chassis lubricating system, a valve 80 is held normally by a spring 84 so that lubricant in an air vessel K is discharged through a passage 103 and passages in the valve 80 leading to distributing lines which are fitted at the terminals with drip plug or resistance fittings. The valve is moved against the reaction of the spring 84 by a rotating arm 75 to cut off the discharge of lubricant and open the air bell K to a supply of lubricant under pressure admitted at the nipple L. The arm 75 is driven from a shaft 40 through a reduction gear 46 .. 65 and ratchet teeth 67, 68. The spindle 56 carrying the arm 75 has a handle 131 which can be operated manually to enable a discharge of lubricant to be made when desired, suitable indicia being provided on the handle 131. The driving shaft 40 may be rotated by any part of the engine, or it may be driven by a wheel rotated by air or lubricant pressure or by any available source of energy. A spring-controlled piston, sylphon, or diaphragm device, with or without an adjustable stroke, may replace the air-bell K. Instead of using a sliding valve 80, the admission and discharge passages of the accumulator K may be controlled by separate spring- controlled valves actuated by a single or by independent cam devices. The supply of lubricant may be from the engine lubricating pump at the normal or at a higher pressure, or a separate oil pump, which may draw from an oil supply independent of the engine oil, may be provided. In a modification in which the device is driven from the speedometer shaft, the oil supply leads from the engine oil pressure gauge piping, and actuation of the accumulator is indicated by momentary fluctuation of the gauge needle. In another modification, a driven cam 323, Fig. 24, actuates a spring-urged ball valve 314 between an oil supply pipe 312 and a measuring chamber 327 containing a loose piston 328 pressed by a spring 336. When the valve 314 is open, oil from the pipe 312 flows into the chamber 327 and forces the piston 328 to the right to eject oil in the right hand end of the chamber 327 through a non-return valve 331 to the distributing pipes. When the valve 314 closes, the piston 328 moves to the left and the right hand end of the chamber 327 is recharged.
