Title: Improvements relating to winding or hoisting systems
IPC: B66B1/08
Filed: 1924-10-07
Abstract: 245,500. Raeburn, C. E., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 7, 1924. Stopping automatically at end of run.-The electric winding or hoisting system described in Specification 209,595 is modified by positively connecting the solenoid armature 21 and the bypass valve 15 in the cataract cylinder 3 which it controls in order that the load may be retarded rapidly at the end of the run irrespective of the speed. The control lever 19 of the valve 15 is connected positively to one arm of a bell crank lever 20, the other arm of which carries the core 21 of the solenoid. The arrangement is such that as long as the solenoid is energized the valve 15 is held in such a position that it restricts the flow of damping medium from one end to the other of the cylinder 3, and prevents rapid braking action. The solenoid is de-energized only when the switch 23 is opened by the depth indicator 14 near the end of the run. As a short interval occurs between the starting of the winding motor 7 and the excitation of the generator 24, the first few studs 27 of the rheostat 25 are short-circuited so that no resistances are switched into the circuit 22 during the interval.. The switch 18 may be capable of being coupled with a switch in the circuit 22 to permit rapid braking in case of emergency irrespective of the position of the load.

Abstract: 814,206. Hydrodynamic torque converters. BORG-WARNER CORPORATION. Aug. 3, 1956 [Aug. 22, 1955], No. 23972/56. Class 69 (2). A torque converter comprises an impeller 30, a turbine 31, a reactor 32 mounted on a stationary part by a one-way clutch, and floater elements 33, 34 which are rigidly interconnected and mounted so as to be freely rotatable. The floater elements function, under stall and relatively high torque multiplication conditions, to increase the load on the impeller to thereby enable the converter to absorb more torque and to deliver a greater output torque. Under conditions of relatively low torque multiplication, the floater elements decrease the load on the impeller to enable the driving engine and impeller to speed up and allow the engine to deliver more horse-power as the converter clutch point is approached. Also the clutch point occurs at a higher speed ratio (turbine: impeller) than with conventional converters, so that the range of torque conversion is increased. The floater elements, instead of being disposed on either side of the reactor may be disposed on either side of the impeller or turbine, or three interconnected elements may be provided disposed between the impeller, turbine and reactor. The turbine or/and impeller may be in two stages, with a floater element interposed between the stages.
