Title: Speed tracking circuit for multi-motor drive - has amplifier with controlled limiting characteristic in each motor control circuit with feedback to all speed control amplifiers
Inventor: GOLDE ERNST DIPL ING
IPC: H02P5/50
Filed: 1977-09-09
Abstract: Each motor has a tachometer speed feedback and a common speed reference connected to a speed regulating amplifier (3). Between this amplifier and a current regulator (5) is an additional amplifier (81) with a controlled (82) limiting characteristic corresponding to armature current limiting. The difference between the input and output of each of these amplifiers is applied to an amplifier (76) providing a common feedback path for all the regulating amplifiers. This feedback signal modifies the speed reference for all the machines. When the limiting feedback responds the input to all motors is restricted until the excessive individual input vanishes. The circuit allows the omission of separate overload protection and its coordination with the control.

Title: Lead recovery from sulphidic source - comprises halogenation, brine leaching and purification of leach soln. by redn., then oxidn.
Inventor: UM RICHARD TAE-SUNG TUCSON
IPC: C22B13/00
Filed: 1979-01-23
Abstract: The source is halogenated at elevated temp to form lead halide, and the product is washed prior to leaching with briner. The soln. is filtered to separate elemental sulphur and solid residue and is then treated with a reducing agent followed by filtration. The soln. is next treated with an oxidising agent and again filtered before being processed to recover lead. Pref. the reducing agent is lead sust, sodium sulphide or hydrogen sulphide and the oxidising agent is chlorine, hydrogen peroxide or air. Lead may be recovered by crystallising the halide from soln. followed by electrolysis in a fused salt bath, particularly NaCl-PbCl2. The process yields lead of purity higher than previously available by a process which eliminates the environmental pollution problems associated with pyrometallurgical processes.
Patent DE-2908019-A1 (DE)
Inventor: SIGLE ROLF
IPC: A43B7/22
Filed: 1979-03-01
Abstract: The invention relates to a foot-supporting insole of which the front bounding line (24) extends in front of the ball (28) of the little toe at the outside of the foot and behind the ball (27) of the big toe at the inside of the foot. To enable such an insole to be used in all conventionally marketed shoes and to ensure that correct adaptation to the foot of the wearer will not be necessary, it is suggested to make the insole (2) of resiliently elastic material of substantially constant thickness and to construct it so that it is curved upwardly at the inside (3) of the foot, the stiffness of the insole (2) at least at the outside zone of the foot being so high that the foot rotatingly rolls towards the big toe during walking. Preferably, the length of the insole (2) at the inside of the foot corresponds to a size which is several sizes smaller than the measurement corresponding to the length at the outside of the foot.
