Abstract: In a separator whose centrifugal drum consists of two, in particular, conical parts (1, 23) connected to one another in rotationally symmetrical fashion, the conical parts (1, 3) form in the region of their greatest diameter a changeable annular gap (4) for the discharge of the solids. In order to connect the rotationally symmetrical parts (1, 2, 3) of the centrifugal drum in a particularly simple, space-saving and cost- effective manner, the centrifugal drum parts (1, 2, 3) are connected to one another by means of bolts (9) which are arranged distributed uniformly in the peripheral region in the circumferential direction. <IMAGE>

Abstract: When using a multiple stage hydrocarbon conversion (e.g. reforming) system wherein a hydrogen-hydrocarbonaceous feedstock reaction mixture (10) is processed serially through a plurality of reaction zones (I-IV), each of which contains a particulate catalyst movable downwardly through the reaction zone, catalyst being withdrawn (31) from the last zone (IV) and fresh or regenerated catalyst introduced (28) into the first zone (I), and the effluent (11, 14, 17) from each reaction zone except the last is reheated (12,15, 18) before passage (13, 16, 19) to the next reaction zone, pinning of the catalyst particles is substantially alleviated by the device of charging only a portion (40-80 mole %) of the total hydrogen (2, 8, 10) to the first reaction zone (I), and charging the balance of the total hydrogen (4, 7) to a subsequent reaction zone (IV).

Abstract: The blocking voltage of an electron gun is corrected by periodically removing an input video signal and driving a cathode with a DC stabilizing voltage. A pulse perturbation is impressed upon a control grid and the cathode momentarily conducts more heavily to exceed a predetermined threshold corresponding to the limit of a black CRT picture. A feedback loop detects a response signal from the perturbation of cathode current and stores the response signal in a memory, the latter determining the corrected blocking voltage during normal operation of the gun.

Abstract: There is provided a power source circuit for use with an electric discharge machine which machines a work (W) by a discharge produced between an electrode (P) and the work (W). When an arc forms in a working gap defined between the electrode P and the work (W), the OFF period of a switching element (Q) inserted in a charging path of a capacitor (C) for storing a discharge energy is increased so that a current flowing across the working gap is cut off for a longer period of time than in the case of a normal operation, thereby quickly recovering insulation during arcing.

Abstract: in a master cylinder of the quick-fill type, communication between the quick-fill chamber (8) and the reservoir (131 is : controlled by a valve assembly comprising a pressure responsive valve which opens when the pressure in the quick-fill chamber (8) reaches a predetermined level, and a one-way valve (20, 22) which allows free flow of fluid from the reservoirto the quick-fill chamber. The valve member (20) and seat (15) of the pressure responsive valve have confronting surfaces which define between them, when the valve is closed, a restrictive passage for pressure equalisation purposes, and any dirt becoming trapped between the surfaces is washed away by the fluid flow on opening of the valve.

Abstract: A fully mounted variable width plow of the rollover type or not in which the tractor hitch links (8) are pivoted about generally vertical axes permitting the hitch limited movement in a horizontal plane, which will allow the adjusted plow to maintain correct alignment under the action of the soil. A forecarriage unit (7) is mounted on the rearward ends of the links in a manner such that slight pivotal movement about vertical axes is again permitted. An elongated plow beam (6) extends generally horizontally and inclines to the direction of forward travel and is pivotally attached to the forecarriage unit (7) about a generally vertical axis. A plurality of plow bottom assemblies are each pivotally attached by way of a support bracket (13) to the plow beam (16) and are equally spaced along the plow beam. An elongated coupling member (15) extends parallel to the plow beam and is pivotally connected to each of the support brackets (13) to interconnect the plow bottom assemblies for common pivotal movement. A coupling member (18) is pivotally attached at one end of the forecarriage unit and at the other end to the foremost plow bottom assembly. A double acting hydraulic cylinder 21 acts between the plow beam and the set of interconnected plow bottom assemblies such that actuation of the cylinder results in equal pivotal movement of each plow bottom assembly relative to the plow beam, as well as pivotal movement between the forecarriage unit and the plow beam about their pivotal connection.

Abstract: A clutch mechanism to alow the connection of drive between an operating member (12) having a handle (33) and a drive boss (11) adapted for mounting for instance on the rotatable stem (10) of a fluid flow control valve comprises an externally screw-threaded peg (13) engaged in a screw-threaded bore (26) in the operating member (12), which bore extends parallel to the operating member axis, and a recess (18) in the end face of the drive boss (11) which recess comes into and out of registration with the bore (26) on the operating member on relative rotation thereof. The peg (13) has a head (32) positioned within a counterbore (29) in the operating member, the head having coded projections (37) therearound such that the peg may be turned solely by means of an appropriate key (35). The key is externally screw-threaded and when used to drive the peg (13) into the recess (18) in the driving boss becomes interengaged with screw-threads formed in the counterbore (29); the key may thus be removed only when the peg is disengaged from the recess.
