Abstract: 1416186 Separation of solids from liquids MACHINEFABRIEK BV 13 Nov 1972 [1 Aug 1972] 52155/72 Heading B1D In a method and apparatus for filtering liquid from solid the mixture is applied to an endless filter belt 3, which can be moved above a subjacent suction box or boxes 9 which may be fixed or adapted to move parallel with the belt. When vacuum is applied the filter belt and suction boxes do not move relative to each other on restoration of atmospheric or superatmospheric pressure in the suction boxes a relative displacement of filter belt and suction box takes place. Each suction box is adapted to communicate with separately controllable suction means (e.g. vacuum tanks 10 coupled to vacuum pump 11) with individual control valves 8. Recycled filtrate or fresh wash liquor may be distributed onto the belt through 14 and 15. A belt washing spray pipe may be provided at 21, and a rotatable brush at 32. The filter belt may move continuously, or the boxes being moved in reciprocatory manner, possibly by a pneumatic cylinder. Alternatively the boxes are fixed and the belt moves intermittently. The belt may have its edges inclined upwards by guides to retain the mixture on the belt.

Abstract: 1,168,648. Making cables; drawing. GENERAL CABLE CORP. 23 Nov., 1966 [18 Feb., 1966], No. 52357/66. Headings B3A and B3P. [Also in Division H1] A coaxial cable has an outer conductor whose inner surface is roughened to tightly grip the core insulation. This roughening of the outer conductor is carried out at 15, preferably by sand blasting, before the conductor is formed in a forming die 16 around the cable core 10 and seam welded at 32 with a larger diameter than required, the cable then being drawn through a sinking die 42 to reduce the diameter of this conductor by 5 to 40% so that it squeezes on to the core insulation. The conductor thickness is not changed by the drawing operation. The cable is pulled continuously at uniform speed past the welding station and sinking die by a capstan 50. Annealed aluminium is used as the condutor material.

Abstract: 1528939 Automatic control SPERRY RAND CORP 22 Dec 1975 [23 Jan 1975] 52358/75 Heading G3N In a semi-automatic take-off control system for an aircraft a control column 10 provides pitch-up commands to a mechanical summing device 12 commanding an actuator 13 positioning an elevator 14. The device 12 also receives an input from an actuator 20 of an SCAS servo 15. The stick force in commanding a pitch manoeuvre is sensed by a transducer 24 providing a signal which in the takeoff mode is directly fed to a comparator 27. The comparator signal is maintained proportional up to a limit value and compared with an actual pitch-rate from a gyro 32 and applied to modify the operation of the SCAS 15. A decision logic 47, relating weight on landing gear, force on stick and pitch attitude, transfers control to a take-off and attitude command mode when the pitch attitude exceeds a set value 36. The attitude 36 is compared with the actual attitude from a gyro 42 and the limited difference applied to the comparator 27, in opposition to the signal from sensor 24, and integrated 45 and applied to a summing device 33 whereby the desired pitch attitude is attained asymptotically. When control column pressure is released the decision logic transfers control to attitude command mode the reference pitch for which is set in on a source 46.

Abstract: 1413313 Feeding and delivering sheets ADDRESSOGRAPH MULTIGRAPH CORP 21 Nov 1972 [22 Nov 1971] 53991/72 Heading B8R [Also in Division G2] The subject-matter of part of this Specification is identical with that of Specification 1,413,314 but the claims are concerned with controlled transport of documents from a pile 26 to the platen 14 of a copy machine. On initial activation of the copy machine, opening of a gate assembly 48 and driving of a belt 20 are effected temporarily to eject any document still on the platen. On depression of a manual feed switch, a feeder 64 and the transport belt 20 are driven and a time-out period commenced for shut-down if a document does not pass a sensor 107 within a given time. When a document does pass sensor 107, feeder 64 stops immediately and belt 20 stops and copying is initiated after an interval to allow the document to reach the platen. On completion of programmed copying (one or more times) gate assembly 48 is opened and belt 20 is driven again to eject the document and two time-out periods are commenced for shut-down if the leading or trailing edge of the document does not pass sensor 105. When the document does pass sensor 105, gate assembly 48 closes, the time-out period for shut-down recommences, and feeder 64 is driven again. After a jam, operation cannot be recommenced until a manual jam reset switch has been depressed.
