Abstract: ABSTRACT A circuit for controlling the speed of electric drives, whose output produces alternating current at a voltage and frequency appropriate to the particular drive for best efficiency, comprises an inverter driven from a variable d.c. supply (typically derived from the A.C. mains power).  A desired input value, which may be a voltage or a frequency signal, controls a store containing the control values for the d.c. supply, which are output in accordance with the value of the input signal, to control the voltage output of the inverter.  The desired input value signal also controls a further store whose read out speed is dependent upon the input value signal, and which thus determines the frequency of output of the inverter.  Selection means allow only certain of the stored values to be used as appropriate to the drive which the inverter is to feed.  The store for the d.c. supply feeds a digital to analogue circuit so that analogue control signals are fed to the d.c. supply.

Abstract: ABSTRACT          DEVICE FOR TRANSPORTING AND/OR SPREADING LIQUIDS.      A manure spreader comprises a tank (1) for receiving liquid manure from a pit (61). The manure enters the tank (1) through a conduit (60) temporarily connected to an inlet (2) by a coupling device (46).          To spread the manure, a distribution member (16) is fitted to the inlet (2) (which then serves as an outlet). A valve (3) is provided for shutting off the inlet (2) from the tank (1). A control linkage (21) is provided for operating the coupling device (46), the distribution member (16) and the valve (3).  The control linkage (21) in construct -ed so that the valve (3) only opens when the inlet (2) is connected to the conduit (60) or the distribution member (16) to avoid the unpleasant effects of accidental manure spillage.

Abstract: ABSTRACT OF THE DISCLOSURE A foam extrusion die assembly includes a die body and a pair of spaced cantilevered lip members having opposed lips defining an elongated, arcuate die orifice through which extrudate moves both laterally and axially outwardly relative to the lip members. Each lip member further has an axially extending flexible leg and a foot at the end of the leg opposite the lip. Each foot is adjustably and sealingly clamped to the die body by a retainer bar whereas each leg is free to flex to pivot the lips with respect to each other. Adjustment screws journaled in the die body vary the spacing between the feet of the lip members and pivot the lips about the flexible legs to produce a desired die orifice size and shape.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a method and an apparatus for the mass separation of a liquid mixture through fractional crystallization, wherein the crystal layer is crystallized on the indirectly cooled wall of the crystallization zone.  The mass transfer occurs in thin boundary layers which are produced by rising gas bubbles which glide as closely as possible along the heat-dissipating surfaces.  The method is well suited for products which form only a soft crystal layer with a rough surface.  It is carried out in a vertical pipe heat exchanger into the pipes of which     there extend into the lower part thereof gas-inlet pipes     which are mounted in the middle and are secured with centering pins       The maximum inside diameter of the pipes is dependent upon the optimum thickness of the crystal layer and of the concentration of the crystallizable component in the feedstock.

Abstract: ABSTRACT      An improved battery utilizing a hydrogen rechargeable anode of a disordered non-equilibrium multicomponent material including one or more elements forming a host matrix and at least one modifier element incorporated therein.  The anode is capable of electrochemically absorbing hydrogen from an electrolyte during application of a charg-ing current thereto.  The hydrogen is stored in the anode bulk until discharge is initiated, where-upon an electrical current is produced when the hydrogen is released.  The superior battery of the invention has attained high density energy stor-age, efficient reversibility, high electrical efficiency, bulk hydrogen storage without struc-tural change or poisoning and hence long cycle life and deep discharge capability.
