Patent GB-648240-A (GB)
Title: Improvements in or relating to control systems
Inventor: MEREDITH FREDERICK WILLIAM
IPC: G05D1/08
Filed: 1947-08-25
Abstract: 648,240. Automatic control systems for aircraft. SMITH & SONS (ENGLAND), Ltd., S. Aug. 25, 1947, No. 23455. [Class 38 (iv)] [Also in Group XXXVIII] In an aircraft aileron control system the aileron servomotor is controlled by an amplifier supplied from the output of an integrator to the input of which is applied the difference between signals proportional to the rate of roll and rate of aileron movement plus a signal proportional to the magnitude of roll of the aircraft. As shown, the opposed signals from the rate of roll gyro 5 and the aileron signal generator 22 are applied with the output from cross-level indicator 7 to the stator winding 55 of the integrator motor 53 which therefore positions the tapping 48 of potentiometer 49 in accordance with the time integral of the applied difference signal. The outputs from 49, 5, 22 and the monitor 7 are in series and are amplified at 21 and energize the aileron servomotor. Specifications 576,248, 576,249, 576,351, 611,005, [Group XXXVIII], 617,240, 621,473 and 642,471, [Group XL (c)], are referred to.
Patent GB-958693-A (GB)
Title: Improvements in or relating to article transfer apparatus
IPC: B23Q7/14
Filed: 1961-06-28
Abstract: 958,693. Machine tool details. CESKE ZAVODY MOTOCYKLOVE NARODNI PODNIK. June 28, 1961 [June 30, 1960], No. 23464/61. Heading B3B. [Also in Division B8] A reciprocating bar 1 engages and moves a plurality of workcarrying carriages 19 by means of respective pins 18. Each pin 18 is carried by a slider 5 which slides in a slot 4 formed in the bar 1. The pin assumes the upper engaging or lower non-engaging position in accordance with the position of the slider; and the slider is held in its upper or lower position by the engagement of a catch 6 in a notch 23, the catch being carried by the slider. The bar 1 is reciprocably driven by driving means 2 and a rack 12 carried by the bar, the limits of movement being defined by stops 13. The slider is displaced upwards or downwards by the engagement with stop 14 or 15 of a bolt 8 carried by the catch 6, the engagement causing the catch to pivot about an axis 7 to release the catch from the notch 23 to free the slider for movement. The bar therefore performs a uniform reciprocating stroke whilst the carriages are thereby displaced, thereby differing distances in dependence on the position of stops 14 and 15. Second embodiment (Fig. 7).-The reciprocating bar carries a plurality of screws 26, each screw carrying a nut 27 and having a slot 32 which engages a pin 25 of a load-carrying carriage 19. As the bar advances, the nut advances, being prevented from rotation by the engagement of a pin 28 upon a rail 31. When the pin 28 passes beyond the rail 31 and bumps against a stop 14 or 15, the nut rotates to release the carriage. The setting of the stops 14 and 15 determines the displacement of the carriage.

Filed: 1939-08-15
Abstract: 533,641. Variable pitch airscrews. JACKSON, O. C., JACKSON, M., and BURNETT, N. R. Aug. 15, 1939, No. 23488. [Class 114] In a variable pitch air screw in which the pitch of the blades is related to engine speed through a governor and a hydraulic link, the hydraulic pistons 14, coupled by toggle links to the gear for controlling the pitch of the blades, work in cylinders 11 arranged at right angles to the airscrew shaft axis. The engine-driven pump 23 builds up pressure in the cylinders 11 against the action of centrifugal force. The slide valve 28 regulating the control in the system is controlled by the spider 29 from the bellcrank flyweight 30 and the spring-loaded governor the load on which is controlled through the Bowden wire 42. A cut-out valve is provided so that when closed communication between the pump 23 and the cylinder 11 is closed so that the airscrew pitch can be locked independently of the governor.

Abstract: 614,881. Supports for curtain rods ; brackets. LYNN, P. J. Aug. 10, 1946, No. 23733. [Class 52 (v)] A support for a curtain rod comprises a portion fixable to a wall, &c., and a movable portion for carrying the rod, the two portions having interengaging corrugations and one portion being adapted resiliently to embrace the other to prevent movement perpendicular to the general plane of the corrugated surface. The fixable portion is formed from a substantially rectangular strip of sheet material bent to form two limbs, one limb a of which is formed with corrugations b, the other limb c containing screw holes d. The movable portion, also formed of sheet material, has one end folded on itself at e to provide a clip, the two parts f, g of which are corrugated to grip the part a of the fixable portion, the remainder of the movable portion being bent at right angles to the parts f, g, and bent to form a tubular socket j to receive a curtain rod k. In a modification (Figs. 4 and 5, not shown) the movable portion has a spigot fitting into a tubular curtain rod, instead of the socket j.

Abstract: 501,146. Sawing; hydraulic machines. ROBINSON & SON, Ltd., T.; and ROBINSON, J. C. Sept. 4, 1937, No. 24170. [Class 145 (ii)] [Also in Group XXIX] Hydraulic apparatus having a differential piston for operating a cross cut saw provides means for admitting liquid on the larger area in stages to secure a variable forward speed at the beginning of the stroke, the liquid behind the piston being expelled on the return stroke at a constant rate. The differential piston 13 operating the saw works in a cylinder 6 provided at its back end with a fitting 7 having an inlet 8 from a pump 9 through a valve 17 automatically as well as manually controlled. The exhaust opening 12 is provided with a one-way spring-controlled valve 16 and the outlet opening 11 with an adjustable screwcontrolled valve. The opening 14 is uncovered by the piston only at the end of the stroke, while opening 15 is covered only as the piston passes it. These two openings are both adjusted by a screw opposite opening 14. To start a forward stroke, valve 17 is adjusted, as shown in Fig. 4, to admit liquid to both sides of the differential piston 13 which moves forward with increasing speed as the openings 14, 15 are uncovered. To effect the return stroke, valve 17 is adjusted to supply liquid to the left side of the piston only, the other side being connected to exhaust so that at first all the openings 11, 12, 14, 15 allow release of liquid. As openings 14, 15 are covered, the piston slows up and remains at rest with liquid circulating through opening 15 until valve 17 is adjusted to supply both ends, as in Fig. 4, when another forward stroke begins.

Abstract: 1476058 Recovering mercury SOLVAY & CIE SA 5 June 1975 [22 July 1974] 24261/75 Heading C7D Mercury is recovered from an aqueous suspension of Hg by passing through a filter, washing the filter periodically with water to entrain the Hg in suspension in the water, passing steam through the suspension, condensing the mixed vapour of water and Hg, and separating the Hg. In an example spent brine 1 from an electrolytic cell containing Hg as chloride is treated with Na 2 SO 3  at 2 to remove chlorine and oxygen, Hg is produced in the metallic state using FeSO 4  as reducing agent FeCl 2 , hydrazine or sodium borohydride may also be used at 3, and the aqueous suspension 4 is passed to filter 5. Periodically, e.g. every 2 days, the process is stopped and wash water 7 is passed up through the filter 5, the wash water 7 being preferably non-oxidizing to metallic Hg, the suspension 8 of Hg and other solids being fed to a settling tank 9 where the supernatant liquor is decanted off, the concentrated suspension 11 passing to a buffer vessel 12, from which a stream 13 of suspension is fed to column 14 into which steam at 180‹C is injected. A stream of mixed vapour of H 2 O and Hg 17 passes to condenser 18 and thence to decautation vessel 19 for separation. The discarded water, containing small amounts of Hg, 10 and 20 may be used as wash water 7 or added to 1 or 4. Electrolytic sludges containing metallic Hg may be added at 12.
