Title: Improvements in and relating to radio apparatus for the measurement of distance
IPC: G01S1/02
Filed: 1946-04-12
Abstract: 615,667. Phase measurements. CLEGG, J. E. April 12, 1946, No. 11358. [Class 37] [Also in Group XL (c)] A device for measuring and indicating the phase difference between two applied signals has input terminals 31 and 32. Input 31 feeds in parallel valves 29 and 30 so that similar phased signals are generated in tuned circuits 43 and 44. Signals from input 32 are also divided into two parts feeding transformers 36 and 37, but owing to the network 34, 35 the signals in these transformers are in phase quadrature. Tuned circuit 43 is connected to a bridge modulator circuit including rectifiers 45, 46 arranged so that the signals therefrom are mixed with the output of transformer 37 to give an output voltage at c, d, that is a function of the phase difference of the applied oscillations. A similar bridge circuit mixes the output of circuit 44 and transformer 37 so that its output at e, f, is also a function of the phase difference of the signals applied. If conjugate coils 57, 58 of an indicator with a full sweep pointer are connected to c, d and e, f, the currents in them will be proportional to the sine and cosine respectively of the angular phase difference between the applied signals and the pointer will take up a position indicating the angle.

Filed: 1950-05-10
Abstract: 702,273. Jet propulsion; gas turbine plant. LYSHOLM, A. May 10, 1950 [May 18, 1949], No. 11680/50. Class 110 (3). [Also in Group XII] In a gas turbine plant with reheating of the working fluid, the turbine exhausts into the reheat chamber through a diffuser which has means to divide the exhaust gases from the turbine into two streams before they rejoin in the reheat chamber, the inner stream being given a tower axial velocity than the outer stream by deflection of this stream in a substantially radial direction. The exhaust gases from the turbine 14 pass through a diffuser 140 into the reheat chamber 142. An annular vane 141 or a number of circumferentially placed vanes, mounted in the diffuser divide the gases into two streams 151, 152. The inner stream 152 is deflected substantially radially inwardly and consequently has a lower axial velocity than the outer stream 151. A zone of return flow 143 is formed where the two streams rejoin into which the fuel is injected through nozzles 144. A variable area propelling nozzle is formed by two pairs of pivoted screens 147, 148 spaced apart so as to form a slot 149 through which air is induced by the flow of gas.

IPC: G21C13/06
Filed: 1961-03-30
Abstract: 942,581. Valves. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 30, 1961 [March 31, 1960], No. 11715/61. Heading F2V. A percussion actuated valve, e.g. for detecting breaks in the fuel-element sheaths of nuclear reactors, has a body 2, 3, 4, Fig. 1, the parts 2, 4 embodying anvils 6, 5, respectively, and the part 3 being provided with fluid inlet and outlet passages. A rod 7 slidable in the body carries an obturator which in one position seals off the fluid passages by means of slidable spring-loaded elements 10, 11, and in another position interconnects the fluid passages by a tubular portion 8. The obturator is held in each of its two operative positions by a tumbler spring 15 associated with two levers 16, 17 bearing upon stops 18, 20 or 19, 21. A magnetic member 22 on the rod 7 enables the open or closed valve position to be detected by an external magnet. The valve is operated by applying a blow to either one of the anvils 56. In a modification, the obturator is replaced by a single beat lift valve and a magnetic impact-member is disposed between the lower anvil and valve stem. The lower anvil embodies a magnetic insert which coacts with the impact member to hold the latter away from the valve stem until the anvil is struck to open the valve. The magnetic means may be replaced by a spring. In a further modification, one anvil is dispensed with and the remaining one is made up of a central head 32, Fig. 3, and an annular head 33. A spring-loaded mass 34 acts on the toggle linkage to open the valve when the annular head 33 is struck whilst a blow on the central head 32 causes the valve to open. The blows are struck by an annular hammer arrangement which may be actuated manually, by spring means or pneumatic power; electrical actuating or triggering means may be provided.

Abstract: 494,315. Scaffolding. SYLVESTER, W. April 24, 1937, Nos. 11778/37 and 12284/38. [Class 20 (ii)] A bracket for attachment to a post e comprises clamping members such as claws g' which coact with a cam d to clamp the bracket to the post, the cam being formed on a member which is adapted to support a horizontal scaffold member or the end of a strut b in such manner that the supported member exerts a force to tighten the clamp. The strut shown is supported by a socket a which is attached to three plates c which carry the cam. The cam consists of a curved plate welded to the plates c and the unit thus formed is mounted on a spindle carrying the arms y of the claws. The spindle is formed in two parts f, f<1> having overlapping ends and one part f thereof is prevented from moving axially by means of a stop h. The part f<1> can be moved axially outwards when a stop h<1> carried thereby is moved clear of a lug i formed on one of the outer plates c, and in the outer position of the spindle the claws can be passed over the flanges of the post. In a modification, the cam is suitably shaped to fit a circular post and the claws are adapted to engage with flanges of a semicircular plate embracing the opposite side of the post. In another modification, one of the claw arms is pivoted on a pin passing diametrically through one end of the spindle so that it can be swung outwardly when the bracket is fitted in position. According to a further modification, the lower face of the bracket is formed as a socket adapted to receive the upper end of an extra post which takes a portion of the load exerted by the struts or the like. To provide a resilient support for the strut, the socket a, according to a further modification, is replaced by a leaf spring which is suitably curved to constitute the cam surface which bears against the post.
