Title: Improvements in and relating to the testing and adjusting of internal combustion engines and/or their carburetters
IPC: F02M1/00
Filed: 1933-11-16
Abstract: 433,695. Spray carburetters. NEESEN, A., 40A, Cecilienstrasse, Zehlendorf-Mitte, Berlin. Nov. 16, 1933, No. 32024. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 28, 1934]. Application for addition to 429,260. [Class 7 (iii)] The parent Specification describes a method of testing a carburetter in which a nozzle similar to a fuel nozzle, is introduced into the mixing chamber adjacent the nozzle to measure the vacuum and from the measurement obtained the quantity of fuel discharged is calculated and compared with that known to be necessary, and the carburetter is adjusted until these quantities agree. If the values of the vacua measured vary, turbulence is present, and the carburetter has to be adjusted until the vacuum is constant. According to the invention, after eliminating turbulence, the output of the engine is investigated as to constancy to test the uniformity of atomization of the fuel. If the output varies the fuel is imperfectly atomized and further adjustment of the carburetter is necessary. This adjustment may consist in (1) varying the temperature of the air, (2) regulating the velocity of the air at the nozzle by altering the cross-section of the mixing chamber at the nozzle or the resistance factors in the air conduit, (3) altering the shape, dimensions position or number of the fuel nozzles, or (4) altering the amount of suction.

Abstract: 670,335. Winding yarn. ZBROJOVKA BRNO NARODNI PODNIK. Dec. 13, 1948 [Dec. 13,1947], No. 32172/48. Class 120(ii) A device for holding bobbin &c. during wind ing and replacing full bobbins by empty bobbins in automatic yarn winding machines the full bobbin on completion of the winding operation being removed by a turning move ment of the device from the winding position and an empty bobbin be ing simultaneously brought to the winding position is characterized in that driving- an< counter - head plates 4, 23 for the bobbins are mounted on a shaft 2 which is axially movable with respect to a driving spindle 11. The cop 22 being wound is gripped between conical elements 5, 30 held in the respective plates 4, 23, the cop being driven by the spindle 11 through a gripping device 6 of dished form. The element 30, during winding is supported by a reciprocable counterspindle 31 spring-pressed at 32. The empty cop-tube 21 carried between heads 5<SP>1</SP>, 30<SP>1</SP> on the plates 4, 23, and fed into position from a pivotable magazine (not shown), is held in place by spring- pressure and ready to be forwarded to the winding position when the holder is rotated, through a one-way clutch 13, by rack and pinion mechanism 15, 18. While winding is in progress a stop 17 presses against the shaft 2 and a further stop 35 against the plate 23. When the cop 22 is completed, mechanism (not shown) withdraws the spindle 31 against the spring 32 and withdraws the stop 17. The spring 16 then moves the shaft 2 together with the plates 4, 23 to remove the head 5 from the driving spindle 11. As the plate 23 moves away from the stop 35, the spring 28 moves the plate about the pivot 25. The movement of the plate 4 removes it from the action of bars 38, which prevented rotation of the holder during winding, and a lug 37 on the traversing drum 36 contacts an arm 39<SP>11</SP> at the end of a wind, to move a locking projection 39<SP>1</SP> from the plate 4 to allow the rack and pinion mechanism 15, 18 to rotate the holder through 180 degrees into contact with a plate 41 to bring the tube 21 into winding position and allow removal of the full bobbin. The stop 17 now moves upwardly to lift the shaft 2 and force the head 5<SP>1</SP> towards the driving spindle 11, and the spindle 31 is moved against the element 30<SP>1</SP>. The traversing drum has returned to its initial position so that the yarn is caught up by the gripper and winding begins afresh.
