Abstract: ABSTRACT                    DC-DC Converter A switched mode power supply in which the power switch (TR1) is modulated by a resistance-capacitance oscillator (COM, R1-R5, CT).  During each on-period of the switch (TR1) a secondary winding (WS) of a sense transformer (TX2) develops a unipolar sense voltage which is applied to a capacitor (CT) in the oscillator while it is charging so as to vary the charging time and hence the on-period, the off-period of the switch  (TR1) being constant.

Abstract: ABSTRACT         In pumping of liquid or suspension containing gas with a centrifugal pump, problems can arise in that a gas bubble, which can spoil the pump function, is formed at the pump wheel central parts.  Through the invention, the gas bubble periphery is given a wave shape and current-detecting electrodes are inserted at different distances from the pump shaft.  Through the wave form the electrodes enter partly in current conducting contact with liquid or suspension and partly in non-current contact with gas, whereby a registerable pulse train arises.  The gas bubble size can be regulated by controlled discharge of gas, so that the pump gives the desired pressure head and volume capacity.  Through the wave shape also the pump speed of revolution and power consumption can be controlled, so that the highest possible operating efficiency is obtained.

Abstract: A Device for Locking a Container Abstract of the Invention Medium-size containers with corner fittings (21) that are not in accordance with ISO specifications may be locked to ISO locking elements (25) of the type provided on loading areas of container transport vehicles by means of locking plates (10) movably disposed inside the hollow frame elements (11) of the containers, provided the container frame has a corresponding width. The locking plate (10) has an overall width that corresponds to the clear diagonal dimension of the frame element (11) and is provided on its outer longi-tudinal edge with cut-outs (12, 13) in the region of which the remaining width of the locking plate corresponds to the clear width of the frame element (11). For locking the container, the locking plate (10) is adapted to be moved so that one (16) of the webs defined by the cut-outs (12, 13) extends outwards through an edge hole (22) that may be formed in the frame element (11) and a further web (18) extends outwards through a corner opening (28) of the corner fitting (21). In this locking position the locking plate (10) is pivoted from its diagonal rest position so as to lie flat on the bottom of the frame element (11) and the cut-out (13) is in engagement about the locking member (25).

Abstract: SLUDGE REMOVER AND PROCESSOR              ABSTRACT OF THE INVENTION A sludge remover and processor includes a first vessel holding cleaning liquid and a second, phase separating vessel.  Cleaning liquid from the first vessel is sprayed against a dirty surface.  A vacuum pump keeps the second vessel upper region at a partial vacuum so cleaning liquid and dislodged matter from the dirty surface is sucked into the second vessel.  Solids and liquid are pumped from the second vessel into a solids separator where the larger solids are removed for dis-posal and liquid is pumped into a centrifuge which re-moves fine solid particles.  The fine particles are mixed with a bulk solidification medium for disposal. Oil collection in the vessels is enhanced by the partial vacuum which lowers the boiling point so tiny bubbles are formed to aid separation of the oily and non-oily phases.  Passing the liquid through a centrifuge also aids separation of the oily and non-oily phases in the first vessel.

Abstract: ABSTRACT OF THE DISCLOSURE   A duplexer for use in a feed network for a satellite communications antenna is made in waveguide form and comprises two plate halves each with a pattern of channels on one surface, the pattern on one half being the mirror image of the pattern on the other.  When the two halves are assembled with the patterned faces juxtaposed, a receive filter and a transmit filter with receive, transmit and common ports are obtained. Each filter has a main waveguide and several short-circuited half wavelength stubs in serial con-nection to the main waveguide.  The joint between the two halves bisects the waveguide broadwall and is, therefore, of no electrical significance.  The simplicity of the design lends itself to fabrication as part of a bigger integral assembly consisting of duplexers and other feed components.  After manufacture, no further tuning is necessary.

Abstract: Polyfumaramides with short recurring units of the formula -(CO-CH=CH-COX)-m, where this group has the trans configuration, and where X is the residue of (substituted) piperazine, hexahydropyrimidine or hexahydropyridazine, are prepared by reacting a fumaryl dihalide with an amine. The polymers have high molecular weight, with an inherent viscosity of > 0.2 dl/g (as a solution of 0.5g of polymer/100 cc. of solvent at 30 deg.C). They are generally white solids with a melting point 280 deg.C. They are usually soluble in the normal solvents, and in strong acids, and the solutions are stable over long periods. The polymers can be obtained as fibres or films from their solutions.
