Patent EP-0028603-A1 (EP)
Inventor: SCHINDLER ERNST
IPC: G01J1/46
Filed: 1980-11-17
Abstract: Un convertisseur (photo-diode 1) expose au rayonnement solaire (2) fournit un courant continu proportionnel au rayonnement, chargeant un condensateur de charge (3). Ce condensateur est relie a l'entree (11) d'un commutateur analogique-numerique (12) qui delivre une impulsion de sortie aussi longtemps que la tension aux bornes du condensateur depasse une valeur (U) predeterminee. L'impulsion de sortie commande un commutateur a semi-conducteur (5) de maniere que, pendant la duree de l'impulsion, le condensateur de charge (3) se decharge a travers ce commutateur (5). Etant donne que l'impulsion s'arreterait et que la decharge serait deja terminee lorsque la tension aux bornes du condensateur de charge descend en dessous de la valeur predeterminee, l'impulsion est prolongee. A cet effet et de preference, l'impulsion est ramenee par un condensateur (21) a l'entree (11) du commutateur analogique-numerique (12) tandis qu'une resistance (22) est branchee entre cette entree (11) et le condensateur de charge (3). Pour la mesure de l'energie du rayonnement on compte les impulsions (compteur 6) et pour la mesure de la puissance du rayonnement on utilise un compteur de la vitesse de comptage (7).

Abstract: In this method, the cavity of the hollow valve (1) is completely filled with relatively highly heated cavity filling material (2), in a fluid state, the gases and impurities being flushed out of the valve bore. Subsequently, the hollow valve with the cavity opening is sealed in a gasproof manner to a container (4) which is likewise completely filled with cavity filling material that is likewise relatively highly heated and is in a fluid state, in order then to cool the cavity filling material down corresponding to the required filling level, the particular filling level being determined by a filling level meter, temperature sensor, frequency meter or electrical resistance meter, and a signal to close the cavity opening being given on reaching the desired filling level. The hollow valve is sealed in a gasproof manner by means of a sealing stopper (3) which can be operated hydraulically, pneumatically, mechanically, electrically, or electromagnetically by means of a piston rod (5). Hollow valves produced according to this method are characterised by a high-percentage vacuum, even at high operating temperatures. <IMAGE>

Patent EP-0043947-A1 (EP)
Inventor: DRUTCHAS GILBERT HENRY
IPC: F04C2/00
Filed: 1981-06-24
Abstract: A pump has an inlet, an outlet, and a fluid displacement mechanism operable to pump fluid from the inlet to the outlet. A cheek plate (30) in the pump is movable to control a flow of fluid from the outlet back to the inlet and thereby to vary the fluid flow to a hydraulic system supplied by the pump. Acting on different and unequal surface areas of the cheek plate are two fluid pressure forces. One fluid pressure force is provided by fluid pressure in a cheek plate control chamber (35). The force acts with a spring (31) biasing force to bias the cheek plate into a position blocking the flow of fluid from the outlet back to the inlet. The second fluid pressure force acts on the cheek plate against the spring force and the first fluid pressure force. A first orifice communicates the pump outlet with the hydraulic system, a second orifice (70) communicates the system (63) with the control chamber, and a third orifice communicates the control chamber with the pump inlet. The second and third orifices are sized relative to each other to provide, at a predetermined rate of flow to the system, a fluid pressure in the control chamber (35) which has a ratio to system pressure generally equal to the ratio of (a) the area of the cheek plate surface on which the second fluid pressure force acts to (b) the area of the cheek plate surface on which the first fluid pressure force acts.

Abstract: A sliding vane type rotary compressor having a rotor (16), at least one vane (28-1, 28-2) slidably mounted on the rotor, a cylinder accomodating the rotor and the vane, and end plates fixed to both ends of the cylinder 
     so as to close vane chambers defined by the vane, the rotor and the cylinder at both sides of the vane chamber. The improvement comprises that the compressor is constructed to meet the following condition:     where, a is a value given by the following equation of:     
     8 represents the angle (radian) formed around the center of rotation of the rotor between the end of the vane closer to the cylinder and the cylinder top (27) where the distance between the inner peripheral surface of the cylinder and the outer peripheral surface of the rotor is smallest;   θ, represents the rotation angle θ (radian) at the instant of completion of the suction stroke;   Vo represents the volume (cc) of the vane chamber when the rotation angle θ is θ s ; and   a(θ) represents the effective area (cm 2 ) of the suction passage between an evaporator and the vane chamber. The refrigerating power is effectively suppressed in the high-speed operation without being accompanied by substantial reduction of refrigerating power in the low-speed operation.   
     The above is achieved by forming one or more grooves (18) on the suction side, extending to an angle along the periphery of the cylinder, whose cross sectional area is appropriately calculated in relation to the cross sectional area of the suction port (17).

Abstract: The metal content of complex sulphidic metal raw material is recovered therefrom by means of an autogenous flame-smelting process, preferably carried out in a vortex, with an oxygen-containing gas. The raw materials are smelted in a furnace in the presence of an excess of oxygen and together with an addition of an acid slag former, such as silica, to form a melt which is rich in metal-oxide silicate and poor in sulphur. Any metal phase formed in the furnace is separated from the silicate phase, and non-iron metals present in the silicate phase are recovered therefrom by selective reduction.

Abstract: A wide moving web 12 is coated on one side thereof by passing the web through an elongated pool 37 of non-Newtonian coating liquid. The pool is contained at its opposite ends by walls- or dams 51,52, these dams being spaced a distance less than the width of the web, such that the side edges of the web are not coated. The dams 51,52 are constructed and arranged such that the coating liquid approaches the adjacent web edge in an amount which increases as the depth of the pool of coating liquid increases. Monitoring means view the opposite side edges of the coated web. When the coating begins to retreat toward the centre of the web, pool replenishment is increased. When the coating begins to approach the edges of the web, pool replenishment is decreased. The sensor whose coating is closest to the web edge is in control of the pump. If the coating reaches an edge of the web, the coating apparatus is stopped.
