Abstract: 879,015. Drying grain. BRONSWERK N. V. June 1, 1960 [June 1, 1959], No. 19421/60. Class 34(2) A drying device, particularly for grain, comprises vertical drying shafts which widen out in a downward direction and which are connected at their upper ends to a supply hopper and at their lower ends to a discharge chamber for the dried grain, whilst air is introduced through the discharge chamber to flow in countercurrent to the grain through the shafts, each of which shafts being located between heating shafts connected at their upper ends to a heating medium source and at their lower ends to an exhaust. The grain falls by gravity from a hopper 32 into shafts 31 to a bunker 33 in countercurrent to a flow of drying air introduced by a fan 42 through louvres in the bunker walls, the shafts 31 being located between heating shafts 34 through which passes steam or hot moist air introduced thereto at the upper ends of the heating shafts through a common supply duct 35 and exhausted at the lower ends through a common outlet duct 36. The heating shaft walls have ribs (not shown) to increase heat transfer to the grain and the bunker has a hood of inverted V-shape, which is vertically reciprocal to effect uniform carriage of the grain from the bunker to a lower screw conveyer 39.

Title: Slave gauge control system for a rolling mill
IPC: B21B37/16
Filed: 1966-05-03
Abstract: 1,142,041. Automatic control of rolling. WESTINGHOUSE ELECTRIC CORP. May 3, 1966 [May 12, 1965], No. 19473/66. Heading G3R, In a multi-stand rolling mill, the force between the rolls at one stand is controlled by a signal, computed from the roll force and roll setting and representing error in thickness of the material leaving the stand, which is also applied to control the force between the rolls of the following stand. Fig.2 shows the third and fourth stands of a sixstand mill for rolling hot metal strip 18. A voltage dependent on the force between the rolls of the third stand is produced by a load cell 46 and applied through a filter 54 to an amplifier 58. An integrating amplifier 62 coupled to amplifier 58 through a contact 64 at the start of each rolling operation applies a signal corresponding to the initial force in reverse to the input of amplifier 58 so that a force deviation signal is thereafter applied through an amplifier 66 to a controller 34, e.g. a field controlled generator or thyristor, for operating a roll screwdown motor 22. The output of a tachometer generator 83 coupled to screwdown motor 22 is integrated by an amplifier 86 to produce signal, representative of change of screwdown position, which is also applied to amplifier 66. These two signals applied to amplifier 66 maintain a desired thickness of rolled material from the third stand which is modified as necessary by applying to amplifier 66 a third signal from a radiation gauge 38 to maintain a constant thickness at the output of the mill. A relay 100 controlled by the output of amplifier 66 ensures that only deviations above a predetermined minimum are corrected. Switches associated with a potentiometer 68 may be manually or automatically operated to obtain optimum system gain. A contact 92 re-sets integrator 86 after each rolling operation. A portion of the signal dependent on the change of force between the rolls at the third stand is applied through a potentiometer 106 and an amplifier 67 to a second controller 34 for operating a screwdown motor 22 associated with the fourth roll stand. Signals dependent on change of screwdown position at the fourth stand and change of thickness at the output of the mill are also applied to amplifier 67 to maintain a desired thickness of rolled material from the fourth stand. Signals compensating for acceleration, tension or tail end thickness variations may also be applied to amplifiers 66, 67. A control system similar to the above is applied to the fifth and sixth stands (not shown). Position detectors associated with hydraulic actuators forming loops in the material between stands control the speeds of motors driving one or more of the stands to maintain desired tensions in the strip along the length of the mill.

Title: Means for the deflection of fluid jets
Inventor: MEULIEN HENRY LOUIS PAUL
IPC: F02K1/32
Filed: 1953-07-14
Abstract: 750,621. Jet propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 14, 1953 [July 17, 1952], No. 19536/53. Addition to 691,302. Class 110(3) [Also in Group XXXIII] A modification of a device for deflecting a jet formed by a nozzle in accordance with the parent Specification comprises a body within the jet, having a movable member, said body being so designed that. in one position of said member, the body has a streamlined shape allowing substantially undisturbed flow of the jet past said body whereas a displacement of said member from said position exposes to the jet a fluid intercepting means adapted to deflect said jet, actuating means for displacing said member from said position and resilient means for returning said member to said position. The discharge nozzle 1, which may be rectangular or circular in cross-section carries a rigid transverse member 4 and a pair of profiled deflectors 5, 6 having adjoining faces so shaped that they may be free to rotate on shafts 7 and 8 respectively. The shafts are torsion bars fast at one end with the nozzle wall and each provided at their other end with a pinion 9, 10 respectively engaged by a double rack 11 operated by a cable 12. A conduit 24 formed with orifices 27 and 28, is located within the member 4 and is connected to a source of high pressure fluid such as a tapping from the compressor of a gas turbine. Normally the leading edges of the deflectors 5 and 6 abut and the trailing edges 15 and 16 abut the respective edges 17 and 18 of the member 4. When it is desired to deflect the gas stream the 'cable 12 is operated to displace the deflectors 5, 6 whereby a central part of the stream passes therebetween and is 'deflected outwardly by the member 4 into contact with the convex trailing edge 2 of the nozzle 1. Rotation of one of the torsion bars 7, 8 operates a valve (not shown) which admits pressure air to the conduit 24, the subsequent ejection through the nozzles 27, 28 assisting the deflection of the gas stream. Other embodiments are described. The deflectors 5, 6 may have their profiled faces in contact so that no gas passes therebetween, the pressure jets alone causing deflection of the gas stream (Fig. 6, not shown); the conduit 24 may be omitted and the forward face of the member 4 formed with a double concave wall (Figs. 1-3, not shown); or the deflectors may be replaced by a single or two rotatable elements formed with projecting edges adapted to be located within or projected beyond the external profile of a rigid deflecting member located in the position of member 4 (Figs. 7-11, not shown). Specifications 691,948, 696,088 [both in Group XXXIII] and 750,601 also are referred to.

Abstract: 743,362. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 12, 1954 [July 15, 1953], No. 19611/53. Class 40 (3). In a television receiver employing a " blackspotter " which supplies a blanking signal to the picture tube during the occurrence of interference signals the output circuit of the " blackspotter" valve is connected to the frame scanning circuit so that the voltage pulses which appear across the scanning circuit during frame " fly-back " periods are also effective to blank the beam of the picture tube. As shown in the drawing the "black-spotter" valve 9, the cathode of which is supplied with video signals from the output of the video amplifier 1 via elements 7, 10, 11, 12 supplies a signal to the control electrode of picture tube 7 when the video signal amplitude exceeds a value determined by the setting of potentiometer 14, this valve being such that the picture modulating signals fed to the cathode of tube 7 from amplifier 1 via elements 4, 5, 6, 8 are opposed by the signal from valve 9 so that the beam of tube 7 is "cut-off" (i.e. when the picture signals " whiter - than - white " signals). In accordance with the invention the output circuit of valve 9 is connected to the frame scanning circuit 19 so that the beam of tube 7 is also blanked out during frame " fly-back " periods by means of the voltage pulses which appear across circuit 19 during these periods.

Abstract: 720,018. Treatment of industrial effluents. SOUTH AFRICAN COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Aug. 21, 1951. [Aug. 25, 1950] No. 19693/51. Class 111. In a process for increasing the efficiency of a conventional anaerobic process for the treatment of an industrial effluent charged with organic matter, sewage sludge is fed along with industrial effluents to a separately maintained anaerobic digester which is used as an inoculation digester for the purpose of periodic reinoculation of the conventional digestion plant in which the industrial effluent is undergoing treatment. A process for treatment of wine distillery effluent is indicated by the flow diagram shown, in which the effluent is fed through conduit 3 to a digester 1 which is charged with digesting sewage solids, supernatant liquor, and asbestos or kieselguhr, and maintained with agitation at mesophilic or thermophilic temperature. The digester may comprise a number of units or compartments with circulation from one to another. The discharge from the digester is through conduit 4 to a sedimentation tank 2 from which the effluent is discharged through conduit 5. Part of the sludge and digester liquor is returned through conduit 7 to the digester 1, excess sludge being run to waste through conduit 6a. An inoculation digester 8 receives daily raw sewage solids through conduit 9 and a small amount of distillery effluent through conduit 10. Inoculum is passed periodically from the digester 8 to the main digester 1 through conduit 12 and previouslydigested liquor is passed from digester 1 to the digester 8 through conduit 11. The inoculum in digester 8 is prepared initially by digestion of raw sewage followed by gradual replacement of part of the sewage by distilling effluent.
