Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 14, 1931]. Application for addition to 369,908. [Classes 69 (iii) and 135.] An apparatus as described in the parent Specification has the liquid outlet x formed in a resilient wall closed and opened by a needle valve l moved by a flexible diaphragm e which may be acted on by liquid pressure or controlled by hand. The diaphragm i s retained by a hemispherical cap a held by screws b on a chamber to which liquid is admitted through a pipe k. The movement of the needle l is limited by an adjusting plate r mounted on a screwed stem f engaged by a sleeve attached to a handle e. Rotation of the plate r is prevented by slots engaging fins d. The needle l passes through a sleeve m retained in position by a spring o, and carrying a cylindrical head t provided with inclined grooves u leading to a wheel chamber v closed by a centrally perforated soft rubber pad p against which the pointed end of the needle l presses. In a modification the screw g securing the needle l to the diaphragm passes therethrough and engages the stem f to allow hand operation of the valve.

Title: Improvements in artificial alternating-current networks
IPC: G06G7/63
Filed: 1956-11-12
Abstract: 838,880. Testing circuit breakers. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Nov. 12, 1956 [Nov. 17, 1955], No. 34525/56. Drawings to Specification. Class 37. In an artificial or model network for studying an actual A.C. network under laboratory conditions; a circuit is provided for measuring the transient oscillatory recovery voltage which occurs under fault conditions when a circuit breaker in the model is opened, the measuring circuit including a superimposed sinusoidal voltage which brings the transient recovery voltage into the same phase relationship with the interrupted fault current as occurs in the network represented by the model. This adjustment of the phase relationship between interruption voltage and fault current is necessary in the measuring circuit as the resistanceinductance relationship cannot be made the same in the model as in the actual network. The superimposed voltage is applied by a phase shifter so as to impart a quadrature relationship between recovery voltage and fault current. Alternatively the superimposed voltage may be displaced by 180 degrees to the recovery voltage for null measurement purposes.

Filed: 1930-11-18
Abstract: 367,043. Aircraft engine cooling. SIDDELEY, J. D., Crackley Hall, Kenilworth, Warwickshire. Nov. 18, 1930, No. 34682. [Class 4.] A concentric annular cowling is arranged in front of the cylinders of an air-cooled radial engine and is adapted to cause air to flow over the crank case and cylinder barrels. The Figure shows a ring 8 arranged with its front edge 10 immediately behind the spinner 7 of an air screw 6 and with its rear edge 11 immediately in front of the forward bank of cylinders of an engine 2, there being an annular gap between the rear edge of the spinner and the front edge of the cowling ring. Ring 8 is similarly shaped to a Townend ring with one of which it may be associated, in which case the latter may partially overlap the ring 8. Owing to the larger diameter of the Townend ring a substantial annular gap is left between the two rings through which the air passes to cool the cylinder heads and valve gear.

Title: Apparatus for the continuous liquid treatment of artificial thread and the like
IPC: D01D10/04
Filed: 1955-12-06
Abstract: <PICT:0796367/IV (a)/1> <PICT:0796367/IV (a)/2> An apparatus for the continuous liquid treatment of artificial thread comprises a cantilever thread-storing, thread-advancing reel having a periphery of a number of spaced interdigitating thread - supporting bar members to advance the thread in the form of a helix, a liquid-spreading member having a circular liquid-spreading periphery within the reel circumference supported by the reel at its free end and rotating therewith, and a stationary liquid supply for directing a stream of treating liquid on to the liquid-spreading member to enable the liquid to travel to the inner surface of the reel and envelop the thread helix.  As shown in Fig. 1, a reel 10 comprises two rigid reel members 11, 12 each having a periphery of longitudinally extending bar members 13, 14 respectively.  The reel members are arranged in an interleaved relation and each reel member rotates about its own individual axis (not shown).  The reel member 11 is concentrically mounted on a shaft 15 shown extending through a hub 17 so as to rotate therewith, The end of the shaft 15 has a bolt 18 which holds a washer 19 against the hub 17 to prevent displacement of the reel member 11.  Since the reel members 11, 12 are arranged to rotate about offset and askew axes, thread will be advanced in the form of a helix lengthwise of the reel periphery. The reel member 11, being secured to the reel shaft 15, serves as a driving means, through bar to bar contact, of the second reel member 12.  Treating liquid from a feed pipe 23 is allowed to flow on to the narrower protruding portion of a frusto-conical member 21 fixedly mounted on the hub 17 and rotating therewith, and is radially flung from the wider portion of the member within the reel on to the inner surfaces of the reel bar members and the thread helix.  Excess liquid is collected and carried away by a trough 25.  When it is desired that a liquid film blanket should flow countercurrent to the direction of travel of the helix, the reel 10 is mounted in the support 24 at a small angle, e.g. 6-10 degrees, to the horizontal, the unsupported end of the reel being higher than the other.  The liquid-distributing and spreading member 21, instead of having the frusto-conical shape shown in Fig. 1, may have the shape shown in Fig. 4, in which the surface of the frusto-conical portion 38 of the spreading member ends in a reverse curve 39 enlarging the member, so that the edge from which the liquid is flung off centrifugally is near the reel bar members 40. Specification 413,414, [Group IX], is referred to.
