Title: Valve having an offset butterfly member
IPC: F16K1/226
Filed: 1973-02-27
Abstract: 1384353 Valves PONT-A-MOUSSON SA 27 Feb 1973 [22 March 1972] 9684/73 Heading F2V  In a butterfly valve having a valve disc laterally offset from the axis X-X of its trunnions 3 and co-operating with a downstream bead 14 on a resilient sleeve 4, the distance R between the axis X-X and the radial bearing surface 8 on the valve body is less than the distance L between the radial bearing surface 13 of the sleeve and the axis Y-Y of the trunnion receiving apertures 15 in the free state of the sleeve, and the diameter d of these apertures 15 in the free state of the sleeve is less than the diameter D of the trunnions. There is thus a greater sealing force f 2  between the trunnions and the sleeve on the downstream side than that force f 1  on the upstream side, these forces tending to equalize due to the pressure differential across the disc in valve closed position.

Title: Improvements in wheels for aeroplane undercarriages or other heavy vehicles
IPC: B64C25/36
Filed: 1939-03-28
Abstract: 527,034. Wheel brakes, SOC D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. March 28, 1939, No. 9732. Convention date, March 29, 1938. [Class 103 (i)] A wheel for aeroplane undercarriages &c. comprises two half wheels in each of which is a brake plate extended inwardly by two walls forming an annular space into which cooling air is introduced. The wheel is made in identical halves joined at the plane X-X, and each half comprises a ring 5 connected by radial arms 6 to a brake drum 7 connected by radial ribs to a rim 11. The fixed axle 1 is clamped between bearing bushes 2 through which pass bolts which secure the brake plate 16 carrying 'the brake shoes and operating cylinders 23, and fitted with the two walls 19, 20. Cooling air enters the space between the walls by a scoop 26 on the plate 16 and passes between arms 6 through a passage 36a formed by sheet metal members 14. Assembly of the two halves of the wheel is assisted by a ring 30. A cooling fluid under pressure may be supplied instead of air.

Title: Pressure operated servo-turbine in combination with control  means therefor
IPC: B23Q5/36
Filed: 1972-03-02
Abstract: 1386348 Machine tool control A MOOSMANN 2 March 1972 [8 March 1971] 9757/72 Heading B3B [Also in Division G3] A pressure operated servo-turbine drive, e.g. for a lead screw drive of a machine tool slide, has an output stub shaft 1 coupled to a differential drive 4, 9, 10, 11 which also receives an output shaft 8 from a stepping motor 6 which feeds in target positional value data so that any difference between the target value and the actual value produces a drive to a toothed cam 19 having a cam surface 20, the said cam surface moving a pin cam follower 32 to actuate a control vane 35 of a fluidic control device 36 which controls the direction and rate of rotation of the servo-turbine. The cam surface 20 has two levels separated by an edge (38) (Fig. 6, not shown) against which the cam follower 32 engages in the synchronous rotation of the shafts 1 and 8. If the turbine shaft 1 leads or lags the shaft 8 the cam 19 is rotated and the cam follower 32 moves to adjust the position of a slotted vane 35 in the fluidic control device 36. With synchronous rotation a control air jet passes through the slot in the vane and is divided equally by a splitting edge into two passages. In a non-synchronous rotation the vane 35 is moved to deflect the air jet to give a greater proportion of air to one of the passages which differentially controls the speed of the turbine until synchronous rotation is established.

Abstract: Method for discriminating between an internal arc and a circuit opening arc detected in a device contained in a metallic envelope having at least a set of busbars(1) and a interrupter switch(2) and fitted with a protection system(4) and a computer(5). The method detects the appearance of the arc(c) by means of a sensor(8) which generates an arc apparition signal(c) and transmits this signal to the computer(5) and determines the time lapse T = t0 - ta between the reception instant t0 of a trigger command(o) for the switch(2) transmitted to the computer(5) and the start instant ta of the acquisition of this signal by the computer(5). If the time lapse T is positive, the arc is deduced to be an internal arc. If the time lapse T is negative and the absolute value is less than or equal to 10ms, the arc is deduced to be an internal arc. If the signal presents a rupture point in the 500ms following its acquisition start, the arc is deduced to be an internal arc. If the signal does not present a rupture point in the 500ms following its acquisition start, the arc is deduced to be an rupturing arc.
