Patent GB-656291-A (GB)
Title: Improvements in automatic control systems for aircraft
IPC: G05D1/04
Filed: 1945-04-16
Abstract: 656,291. Automatic control systems for aircraft. SPERRY GYROSCOPE CO., Inc. April 16, 1945, No. 9525. Convention date, April 15, 1944. Drawings to Specification. [Class 38 (iv)] In an aircraft automatic piloting system a D.C. signal corresponding to a set rate of turn is smoothed or integrated and controls banking of the craft. The following modifications of the automatic aircraft piloting arrangement described in Specification 626,287 are described: (a) In Fig. 1 (not shown) instead of deriving, for the purpose of banking the craft during a turn, an A.C. signal dependent on the setting of the rate-of-turn control knob, a D.C. signal is derived from a reversing potentiometer mechanically coupled to the rate-of-turn knob and supplied from a constant D.C. source. This signal is applied to the grid circuit of a balanced valve modulator giving an A.C. output, the magnitude and phase of which corresponds to the magnitude and polarity of the D.C. input. This.output is combined with the output, at the same frequency, from the bank pick-off associated with the gyro vertical and constitutes the input to the aileron servoamplifier. Instead of deriving the signal for correcting side slip from the output of the rudder servo-amplifier, a pendulum, having its axis parallel to the fore-and-aft axis of the craft, detects side slip and operates a second reversing potentiometer, supplied from a constant D.C. source, the output of which is also applied to the grid circuit of the balanced modulator. The outputs of both potentiometers are connected to the modulator grid circuit through resistance-capacity integrating circuits to smooth out transient effects. In this manner the necessity for byepassing the differentiating portion of the aileron servo-amplifier in the application of the banking and side-slipcorrecting signals is avoided. Biassed diodes limit the input to the balanced modulator. (b) In Fig. 2 (not shown) D.C. banking and sideslip-correcting signals are applied to a balanced valve modulator through integrating circuits as at (a) above, but the banking signal is obtained by rectifying the output of a constant frequency generator driven by an A.C. motor, the speed of which is controlled by the amplified output of a reversing potentiometer supplied from a constant A.C. source and mechanically coupled to the rate-of-turn knob. The A.C. motor serves also to rotate, through reduction gearing, the Selsyn rotor causing turn of the craft. Feedback is provided from the generator to the input of the amplifier controlling the motor. In this arrangement the side -slip -correcting signal is obtained from the output of the rudder servo-amplifier as in Specification 626,287. Specifications 612,804 and 656,329 also are referred to.

Title: Improvements in or relating to draught excluders for doors and the like
IPC: E06B7/16
Filed: 1954-04-01
Abstract: 764,538. Draught excluders. MIDDLETON, A. June 28, 1955 [April 1, 1954], No. 9532/54. Class 20(3)  A draught excluder 1, Fig. 2, adapted to be fixed to the threshold 7 comprises an L-shaped base 2 providing an abutment 4 for the door 5, an upstanding resilient strip 3 being provided on the base 2 parallel to and spaced from the abutment 4, the strip 3 engaging the underside of the door when the latter is closed. As shown, a wooden or metal base 2 has a slot 10 in which the rubber strip 3 is held. The draught excluder 1 is secured by screws 6 to the threshold 7 and may have its under surface recessed to form a shoulder against which a concrete projection on the threshold may engage. The upper surface of base 2 slopes downwardly towards the exterior to provide drainage, water passing away through holes 11 in abutment 4. In a modification the strip 3 is held within the slot by means of a fillet and spaced screws. The strip may be L-shaped, the base of the strip lying against the base of a rebate in the draught excluder and being covered and held by a detachable fillet. In a further modification, Fig. 6, spaced projections 20 on the strip engage the undercut faces of a slot 19. In a further form the projections and undercut slot are continuous. In another construction the strip 3, abutment 4 and base 2 are formed as an integral rubber moulding held in a trough-shaped metal base secured to the threshold.

Title: An improved roller conveyer
IPC: B65G13/00
Filed: 1935-03-27
Abstract: 445,445. Roller - conveyers for vehicle - washing plant. PIQUEREZ, E., 4, Avenue de la Pommeraie, Saint Cloud, France. March 27, 1935, No. 9627. Convention date, Oct. 31, 1934. [Class 78 (i)] A roller conveyer for use in washing and cleaning vehicles comprises a series of driven rollers and a series of idle rollers prevented from rotation in the direction contrary to that of the driven rollers, the arrangement being such that a vehicle transported on the driven rollers is delivered to the idle rollers and can then leave the latter under its own power. In the construction shown, two lines of driven rollers are used, each of which carry the wheels at one side of the vehicle. Each driven roller is mounted between a pair of channel beams 1, being fixed to an axle 7 mounted in water-proof ball-bearings 10 fixed to the beams. One end of the axle carries a chain-wheel 15, all the chain wheels being driven by a common chain 16, Fig. 4, which is deflected by guides 19 so as to engage several teeth on each wheel. The non-driving return run of the chain is guided on the lower flange of the beam without engaging the chain wheels, and is tensioned by a sprocket 31, Fig. 6, carried by a guided frame 27 adjustable by screw-mechanism 34. A water-proof casing 36 encloses the chain wheels and the chain. At the end of the conveyer, the vehicle is delivered to idle rollers fitted with ratchet gear so that it can be run off them under its own power. On the conveyer the driven rollers are spaced sufficiently to oscillate the vehicle during its passage thereover, thus assisting drainage and removal of mud. The conveyer may also be formed by several sections in tandem, each of which can be separately driven, or each section may drive the succeeding section, all the chain wheels of each section then being driven by a common chain. Clutches may be fitted to interrupt the drive of any particular section at will.

Title: Improvements in fluidtight closing means for butterfly valves having a continuous outline
IPC: F16K1/228
Filed: 1959-03-23
Abstract: 879,522. Valves. HENRION, M. C. E. March 23, 1959 [Dec. 3, 1958; Feb. 23, 1959], No. 9954/59. Class 135. In a butterfly valve of the kind in which the valve disc 1 is supported by a spindle that does not pass through the seating area in the valve body so that a continuous, peripheral seal is obtained around the disc when closed the body is formed with an annular recess 7b closed by a sleeve 7a that is welded in position to provide a smooth surface continuous with the bore in the body, and means is provided for applying fluid pressure to the recess when the valve is closed to press the sleeve 7a into contact with the disc. As shown, the valve is actuated by a shaft 9 connected to the disc by an arm 9a and link 9b and is driven by a gear sector (not shown) meshing with a worm 3 mounted on a spindle 2a carrying a hand wheel 2. When the sector engages a stop (not shown) corresponding to closure of the valve continued rotation of the hand wheel causes axial displacement of the spindle 2a against a spring 5 due to the action of the worm. Such displacement is transmitted to a piston 4 which pressurizes a liquid-filled system 6, 6a communicating with the recess 7b. In a modification, the valve is actuated by a nut which moves axially on a rotatable, threaded spindle and is connected to the valve disc by linkage. Displacement of the piston 4 takes place by engagement of the nut with an amplifying lever connected to the piston as the valve disc reaches its closed position. Since, in this embodiment, the threaded spindle does not move axially the hand wheel may be replaced by, e.g. a transmission pulley.
