Abstract: Combinations of an active compound selected from the class outstanding of hydantoin and thiohydantoin derivatives and their salts together with a phosphodiesterase inhibitor. Such combinations have pharmacological effects related to those of the active compound alone but these effects (other than vasodilatory effects) are potentiated by the phosphodiesterase inhibitor whilst the vasodilatory effect is not so potentiated. The combination may be used in medicine either along or in a formulation, for example in the treatment of thrombosis.

Abstract: A piston-and-cyiinder actuator for a tilting cab on a vehi- de has a main piston (38) with a piston rod (40) extendable by application of hydraulic pressure to push port (28) and retractable by hydraulic pressure applied to pull port (30). During retraction return of fluid from expansion chamber (34) is not possible through one-way supply valve (78) but is controlled by poppet valve (68). Valve (68) is spring biassed but can be opened by a combination of differential pressure across the valve and the movement of a pilot piston (66) acted upon by the pressure at the pull port (30). The return path to the push port (28) is by way of a passage (52) in the poppet valve (68). In a modification the pilot piston (66) first acts by way of a floating rod to open a valve in the passage (52). 
     The actuator provides smooth movement with a minimum of bouncing because it prevents the weight of the cab driving the piston rapidly after the cab passes the balanced position.

Abstract: A pilot valve is described for control of a pulse valve for e.g. production of pulses of compressed air. The pilot valve comprises a housing having an inlet (20) and an outlet (10), a movable valve element (12) disposed inside the housing, and means (4,16) for switching said valve element between a closed and an open position, said inlet and outlet communicating in the open position. At least a portion of the interior of the housing presents in one plane a circular shape, the outlet being formed as a radial slot from this portion around at least a part of the periphery. The valve element is designed as a flexible disc which in the closed position is located in said plane to seal the slot with its outer edge at the inner side of the housing. Said means are arranged to switch the valve element to the open position by giving the disc a curved shape so that the outer edge no longer covers the slot.

Abstract: This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base. Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention. The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base. 
     Such coated product has extended service life at temperatures above about 450°F (232°C) and when restored to room temperature possesses a high degree of ductility.

Abstract: A method of manufacturing a one-transistor memory cell using the single silicon gate technique, using a bit line of doped material and a metal word line. Such memory cells have the disadvantage that increasing integration density is accompanied by transit time effects which undesirably reduce the working speed of the device. To avoid this disadvantage, the invention envisages that, after the gate oxidation, an implantation of electricity carriers of one polarity is carried out in the subsequent source and drain region of the selection transistor and of the storage capacitor and this implantation is completed either by an implantation or a diffusion of electricity carriers of the same polarity as in the first implantation in the course of a subsequent process step in the drain and source region. During the application of the silicon layer, contact is made to the doped bit line region with a polysilicon strip. The invention can be applied in memories having a high integration density such as, for example, in 262 kbit memories. <IMAGE>

Abstract: An acidic gas (e.g. CO2) is removed from a gas mixture containing it by contacting the gas mixture with an absorbing solution in an absorption tower (10) of a scrubbing system. The absorbing solution comprises a basic alkali metal compound and a hindered amine activator some of which is converted to a cyclic urea. Acid gas is recovered (in 28) by passing absorbing solution recovered from the absorption tower (10) to a desorption tower (20) of the scrubbing system operated at a lower pressure and / or higher temperature than the absorption tower (10), and part of the regenerated absorbing solution is returned to the absorption tower (10) for re-use. Another part of the regenerated absorbing solution is circulated to a thermal conversion zone (40) wherein it is retained for an adequate residence time and at an elevated temperature to convert at least some of the cyclic urea to hindered amine activator, whereafter the thermally treated absorbing liquid is returned from the thermal conversion zone (40) to the scrubbing system.
