Abstract: ABSTRACT OF THE DISCLOSURE         The rotation side brake plates and the fixed side brake plates are pressed by way of the movement of the brake piston due to the supply of the hydraulic pressure, thereby braking the output shaft.  The guide rod is cantilever supported in the housing.  The guide rod is inserted into the hole in the projecting portion at the outer periphery of the piston.  The return spring is interposed between the flange portion at the end of the rod and the piston.  When the hydraulic pressure is drained, the brake piston is returned by means of the force of the return spring.

Abstract: SYSTEM FOR SEPARATING LIQUIDS  Abstract of the Disclosure A system for separating two immiscible liquids of different specific gravities, such as oil and water.  The system includes a gravity separator and oil-contaminated water is continually pumped into the separator tank by a main pump and is impinged against an inclined baffle which directs the water upwardly toward the top of the tank.  Larger droplets of oil are collected as a layer in the upper end of the tank, while the effluent is discharged from the lower end of the tank to a coalescer unit, where residual oil is removed from the water.  A liquid level sensor is located in the upper end of the separator tank and when the collected layer of oil reaches the level of the sensor, the sensor discontinues operation of the main pump and operates an oil pump to discharge the col-lected layer of oil from the separator tank to an oil recovery location.  The oil collected in the coalescer unit is recirculated and mixed with the oil-contaminated water being introduced into the separator tank.

Abstract: ABSTRACT OF THE DISCLOSURE         In a process for producing a polyarylene thioether having high stability by dehalogenation/sulfurization reaction of an alkali metal (M) sulfide such as sodium sulfide and a dihaloaromatic compound such as paradichlorobenzene in a polar organic solvent, the haloaromatic compound is used excessively in an appropriate range rather than the alkali metal sulfide and the latter stage of the reaction or all period of the reaction is conducted under a powerful stirring condition to a certain degree to obtain the polyarylene thioether wherein the concentration of -SM or -SH groups of the polymer terminal is lowered. The polyarylene thioether thus obtained suppresses the coloration in the processing with an apparatus made of ferrous material such as extruder. Furthermore, the resulting polyarylene thioether contains a very small amount of -SM or -SH groups and is useful for producing colorless and transparent articles by melt processing.

The catheter includes an elongated tubular member having a distal end for insertion into the body and a temperature-activated memory element in the distal end of the hollow tubular member.  The memory element has an initial shape and moves to assume a predetermined shape when heated to a predetermined temperature.  A control system is provided for selectively heating the memory element to the predetermined temperature so that the memory element is moved in a first direction to deflect the distal end of the tubular member and thereby steer or aim the catheter within the body.  A spring assembly is provided for yieldably urging the memory element in an opposite second direction to establish the initial shape and also to aid in returning the memory element to its initial shape when the temperature of the memory element is less than the predetermined temperature.  The spring assembly includes a core member for supporting the memory element and a resilient member.  Both the core member and resilient member are preformed to assume curved shapes and both move to assume a shape other than the preformed curved shapes in response to movements of the memory element in the first direction.

Abstract: ABSTRACT Supply circuit for supplying a smoothed direct current to a load impedance.           A supply circuit comprising an FET as a series element in series with the load resistance.  The supply circuit is fed from the mains network via a rectifier 54 and a smoother 52, causing a ripple voltage to be present on the input terminals 2-1 and 2-2.  The direct voltage component of the input voltage is present across load resistance 60, the alternating voltage component of this voltage being present across transistor 10.  With known supply voltage circuits the voltage drop across the series element is selected to be equal to the maximum peak-to-peak value of the alternating voltage component, causing unnecessary dissipation to be developed at a minor ripple amplitude. This will cause fast ageing of the series element.  The supply circuit in accordance with the invention comprises a comparator 42 comparing the voltage across transistor 10 to a threshold voltage. Comparator 42 controls the charge on the filter capacitors 30 and 32. Consequently, the overall voltage across transistor 10 will never exceed the sum of the threshold voltage and the peak-to-peak voltage of the voltage component of the input voltage. Figure 1.

Abstract: ROBOTIC OR REMOTELY CONTROLLED FLYING PLATFORM            Abstract of the Disclosure A flying platform, propelled by at least one ducted fan causing a vertically downwardly directed airstream in and through a cylindrical duct.  A vane system in the duct has two mutually perpendicular pairs of diametrically opposite first vanes, each extending in from the duct rim toward the center of the duct. Each pair of first vanes provides a pair of generally vertical walls parallel to a diametral line across the duct, and they define duct passages between the pairs of vanes and define quadrants between adjacent pairs.  Each first vane has an upper, fixed, rigid portion and a variable camber flap depending there-from.  A first servomotor with linkages vary the camber of each pair of flaps, so that the camber of the flaps of each pair is at all times the same amount but in opposite directions.  Preferably, there are also four second vanes, one bisecting each quadrant, and a symmetric pair of spoilers is mounted on each second vane. Each pair of spoilers is independently movable, as a pair con-tinuously between a position substantially blocking airflow through the outer portion of said quadrant and a position permitting substantially full airflow therethrough.  A second servomotor with linkages symmetrically varies the position of its spoilers. There may be a radio receiver responsive to remote control signals for actuating each servomotor and its linkages.
