Abstract: 712,273. Cold-cathode tubes. BENDIX AVIATION CORPORATION. June 26, 1952 [Aug. 3, 1951], No. 16136/52. Class 39(1) A cold-cathode gas-filled D.C. voltage regulator tube comprises a cylindrical envelope 1 of conducting material such as nickel-iron which functions as the anode, sealed at one end by a pinch weld 2 and at the other end by a lead-glass seal 9. A rod cathode comprises a portion 5 of nickeliron alloy which is secured in the seal 9 and forms an external terminal, and a portion 7 of platinum. A cylindrical extension 11 of the seal 9 serves to lengthen the leakage path between cathode portion 5 and the envelope.

Title: Hydraulic telescopic lifting cylinder
IPC: B66F3/28
Filed: 1978-12-05
Abstract: In a telescopic hydraulic lifting cylinder comprising a hollow piston 14 slidable in an outer cylinder 1 and forming the cylinder for a piston 3, the latter if desired in turn acting as a cylinder for a further piston and so on, and wherein the annular space(s) 6 between the cylinders is/are filled with liquid whereby extension of all the pistons and cylinders occurs when liquid is supplied to the outer cylinder's pressure chamber 4 through a port 5, a differential piston 18 slidable in the piston 14 moves to allow fluid to flow from the pressure chamber 4 to the spaces 6, 9 in the event of leakage of fluid from the latter. If leakage has occurred retraction of the piston 14 produces an abnormally low pressure in the spaces 6, 9 which causes the differential piston 18 to lift against the counteracting force resulting from a rarefied space 15 beneath the piston 20. This lifting allows fluid to pass from chamber 4 through a port 17, past a ball 28 and through a duct 19 with a spring loaded ball 31 into the spaces 6, 9. <IMAGE>

Title: Apparatus for determining the stiffness of timber and method of grading timber
IPC: G01N3/20
Filed: 1980-01-30
Abstract: In order to measure its stiffness, an item of timber L has a known deflection imparted to it by means of an adjustably positionable roller 9 disposed between two pairs of rollers 1,2 and 3,4 and the load necessary to produce this deflection is detected by means of a load cell 12.

Title: Hovercraft propulsion unit with thrust reverser
IPC: B60V1/14
Filed: 1980-02-05
Abstract: Ducted propulsion unit 18 of a hovercraft has a thrust reverser comprising a deflector 32 within the duct 22 and an outwardly openable door 48 for a side wall aperture 46. The deflector 32 moves between an inoperative position in an axial plane of duct 22 and an operative deflecting position extending obliquely across duct 22. Door 48 is coupled to deflector 32 by a link 60 so that it opens as the deflector moves to its operative position. Air driven down the duct by fan 26 is then deflected through aperture 46 and by the open door 48, to produce a rearward thrust component. With two propulsion units symmetrically arranged, selective operation of the thrust reverser of one or both units produces either a turning effect or a braking effect. For a single propulsion unit apertures 46 and doors 48 can be provided at both sides of the duct and the deflector can comprise independently operable pivoted flaps (Fig. 7, not shown) for selectively deflecting the air to one selected side for turning or to both sides for braking. <IMAGE>

Title: Piston anti-knock back assemblies
IPC: F16D65/18
Filed: 1980-07-10
Abstract: A brake actuator 10 comprising a piston 12 slidably mounted within a cylinder bore 14 comprises an anti- knock back assembly 30 comprising an expanded resilient split ring 32 in frictional contact with a main portion 26 of bore 14 and loosely axially located in an annular groove 28 adjacent a conical head portion 22 of piston 12. The resilient ring 32, when unexpanded, is a sliding fit within the main portion 26 of bore 14, and the resilient ring is provided with abutment spacer means (shaped frustum or leg portion) which, when the ring is placed into contact with an end wall 20 of the cylinder bore 14, the plane of the ring is spaced far enough from wall 20 to allow insertion of the conical head 22 within the ring so as to expand the resilient ring over conical head portion 22 until it snaps into position in said annular groove 28. This gives frictional grip of ring 32 with bore 26, and ring also acts to adjust for friction surface wear to provide constant retraction distance (w-t). <IMAGE>
