Abstract: 614,953. Pneumatic conveyers; screw conveyers. SMIDTH & CO., AKTIESELSKABET, F. L. July 1, 1946, No. 19637. Convention date, Oct. 20, 1943. [Class 78 (i)] In conveying apparatus of the kind to which pulverulent material is fed by air, a device responsive to the level of the material that is being conveyed is operatively connected with a device for controlling the amount of air employed so as to reduce the supply of material to the conveyer whenever the said level exceeds a predetermined height. An excess flow of pulverulent material along the screw conveyer 1, Figs. 1 and 3, causes one or more of a plurality of pivoted vanes 4 to rock and operate one or more of the associated ball valves 9, Fig. 2, which allow air to flow through one or more of the branch circuits such as that formed by pipes 14, 15, 16. The pipe 16, together with pipes 17, 18, is operatively connected to the master valve 21 in such manner that a flow of air through any one of the branch lines stops the main flow of air along pipes 13, 19 leading to the extracting devices 3, which transfer material from the silos 2 to the common conveyer 1, said master valve 21 being actuated by a member consisting of a plurality of diaphragms (one for each branch line), each of which has a centrally-disposed stem 26 at its underside and the upper diaphragm has, in addition, an upstanding stem 27 which actuates the head of the master valve 21 when pressure is applied to any one of the diaphragms 25 through any one of the associated branch lines 16, 17 or 18.

Filed: 1923-08-01
Abstract: 216,395. Watts & Son, Ltd., E. R., and Watts, G. W. Aug. 1, 1923. Angle-measuring instruments. - In a differential-screw fine-adjustment mechanism for scientific instruments the axially moved member acting on the telescope &c. is prevented from turning by a clamp secured to it and having a laterally projecting arm carrying a guide pin working in a hole &c. in the fixed bracket carrying the mechanism. The rotary operating member d having external and internal threads of different pitches engages externally with a bush b secured in the fixed bracket a, and internally with the screw f which is thus moved axially by rotation of the member d. A split collar h is clamped to the plain end of the screw f by a screw l and is formed with an arm m carrying a pin n engaging in a hole o in the bracket a. A plate p secured to the collar by screws r carries a knife edge q on which the telescope &c. bears. The holes for the screws r are slotted to allow adjustment of the knife edge in relation to the axis of the telescope. The milled head c of the member d frictionally engages a graduated drum g reading against a scale s. To bring the instrument to a desired zero position the drum is set to zero and the collar h then unclamped so that the instrument can be set to the desired position by turning the screw f.

Abstract: 516,706. Treating sewage and foul waters. SAMUEL, J. O., and UNIFLOC REAGENTS, Ltd. July 5, 1938, No. 19934. [Class III] A mixture of calcium sulphate with ferric chloride and/or aluminium chloride is used as a flocculating agent in treating sewage suspension or other similar aqueous suspensions of organic matter. The agent may be prepared by mixing a concentrated solution of calcium chloride with a concentrated solution of ferric sulphate and/or aluminium sulphate. The product is obtained as a thick paste or in solid form according to the temperatures of the concentrated solutions and the temperature at which the mixture is maintained during the reaction. Ferrous sulphate may be used instead of ferric sulphate, the ferrous chloride obtained in the mixture being subsequently converted into ferric chloride. A process is described in which sewage sludge is first treated with a starch-salt flocculating gel as described in Specification 435,126, part of the water being then removed and the thickened suspension treated with the flocculating agent of the present invention and filtered. Alternatively the two flocculating agents may be added simultaneously.

A conducting surface e. g. metal strip is electrocoated with a polymeric material deposited from an aqueous dispersion of the material containing a fixed dispersant, e.g. comprising polycarboxylic acid resin solubilized by alkali metal ion, which is reconstituted by mixing at least a portion of the dispersion with make-up polymer dispersed with a separable e.g. volatile dispersant such as ammonia or amine to enrich the polymeric content of the dispersion, and separating, e.g. vaporizing using a vacuum pump, the separable (volatile) dispersant from the dispersion while maintaining the fixed dispersant therein in sufficient amount to stabilize the polymeric content. The aqueous dispersion preferably includes pigment particles, e.g. of TiO 2 , C black, Fe oxide, silicous material or PbCrO 4 .

Title: Control operating circuits for the selective control of plural function electrical apparatus
IPC: G04G5/00
Filed: 1975-05-14
Abstract: The circuit arrangement comprises an operation control circuit (7) in a time-measuring instrument, which can be switched over by an actuator which can be operated by hand and has a plurality of switch positions. The operation control circuit (7) is assigned a protective control circuit for generating during the movement of the actuator from one switch position to an adjacent one a switchover delay time which can be given a fixed setting. In this case, a delay time signal is generated which is of a prescribed length and which preferably lasts beyond the normal switching time, in order to suppress instantaneous maloperations, without in the process having to accept an unnecessarily long delay to the start of functioning of the operation control circuit. <IMAGE>
