Abstract: 601,116. Hydromechanical variable-speed gear. McGILL, D. F. Nov. 8, 1944, No. 21970. Convention date, Oct. 26, 1943. [Class 80 (ii)] [Also in Group XXIX] A hydromechanical variable-speed gear comprises a reaction-housing 14, journalled on aligned input and output shafts 12, 13, and two three-element transmissions, each having first (reaction) elements secured to the housing, second.elements secured together on an aligned intermediate shaft 27, and third elements secured to the input shaft in the case of one transmission and the output shaft in the other. The two transmissions may comprise a hydrokinetic torque-converter in front of (Fig. 1) or behind (Fig. 10, not shown) a planetary gear-train. In Fig. 1, the impeller 23 of the converter is secured to the input shaft 12, its driven member 26 is secured to the intermediate shaft 27 carrying the driving sun 31 of the planetary train, whilst its reactionmember 25 is integral with the reactionhousing 14 carrying stepped planets 32, 34 of the train, the other sun 35 of which is secured to the final output shaft 13. Forward drive is through the stepped planets 32, 34, and reverse is by sliding a planetary idler 41, permanently meshing the driven sun 35, into mesh with a wheel 40 of a secondary stepped-planet pair 39, 40. In reverse the common reactionhousing 14 is held by a brake 48, and, in forward drive, either by the brake or by a one-way detent 19, which allows the reactionmember to rotate forwardly when conditions permit, the drive ultimately becoming one-toone. A spring-engaged friction-clutch 72, actuated through a collar 85, connects together the converter driving and reaction members 23, 25 for unit-ratio fluid-coupling drive. To prevent idle-drag, the converter has a flowarresting' ring-valve 81, operated through a collar 79. In Fig. 10 (not shown) the planetary train is arranged ahead of the converter, the driving and driven shafts in Fig. 1 being, in effect, interposed, and the clutch 72 and reverse are omitted. The planetary gear may impart speed increase or reduction to the converter impeller. Various modified torque-converters are shown, in some of which the driven member initially rotates in the reverse direction, the reverse idler 41, Fig. 1, then being used in forward drive. The Specification as open to inspection under Sect. 91 states also that the friction-clutch 72, for changing from converter to coupling drive, may be governor-controlled. This statement does not appear in the Specification as accepted.

Title: Improvements in methods of and devices for filling a flowable substance into containers
Inventor: STONESTREET GEORGE ALEC
IPC: B65B3/30
Filed: 1952-09-05
Abstract: 734,292. Filling paper bags &c. WALL & SONS, Ltd., T. Aug. 18, 1953 [Sept. 5, 1952], No. 22335/52. Class 94 (1). [Also in Group XVIII] A method of dispensing a flowable substance into a container 88, Fig. 3, e.g. a paper bag includes the steps of. withdrawing a predetermined volume of substance from a reservoir 18, transferring the withdrawn volume to a point vertically above the container to be filled and allowing the withdrawn volume to flow substantially vertically downwards into the container. In the preferred embodiment, rows of containers carried by an endless chain conveyer are filled simultaneously from a series of funnels 29, Fig. 2, of non-contaminating plastic material or metal alloy, a measured quantity being delivered into each funnel by a dipper assembly of non-contaminating plastic material. Each such assembly comprises a semicylindrical ladle a connected by a trough b to a funnel and is mounted on a hexagonal shaft 33 which oscillates it between the full and broken line positions of Fig. 3 to transfer the substance into the funnels 29 from the reservoir 18. The latter is driven in a closed path by four gimbals 74 ... 77 secured to chain drives 68 ... 71 which are driven by further chain drives 66, 67 and sprocket wheels 60, 63 from an electric motor. This movement of the reservoir is synchronized with the movement of the rows of containers 88 so that the latter accompany the reservoir on itsupward movement during the filling operation and is utilized to oscillate the shaft 33 which is provided with three levers 109, 110 and 111. As the reservoir moves downwards, the lever 111 engages a yoke plate 72 and the ladles are held below the surface of the substance until the lever 109 is engaged by a fixed pin 114 towards the end of such movement. During the upward movement, this pin causes the shaft 33 to rotate and hence tilt the ladles so that they discharge into the funnels 29. The lever 110 co-operates with a fixed pin 113 to ensure that the ladles are re-submerged in readiness for the next filling operation. A partition 21. divides the reservoir into a compartment 19, supplied by a pipe 17 and fitted with a baffle 24 which determines the depth of the substance, and a compartment 20 from which the substance drains through a conduit 28 into a rectangular funnel 46 for recirculation. The pipe 17 passes through a rectangular opening in a cover 35 and a baffle 27 ensures a tranquil flow. A pivoted drip catcher 31 which is closed by the approach of the containers before each filling operation is provided. Specifications 732,434, 734,290 and 734,291, [Group XXX], are referred to.
