Title: Improvements relating to water closet flushing cisterns
Inventor: BRYLOV CARLO OSVALD HARTVIG
IPC: E03D1/01
Filed: 1960-02-11
Abstract: 895,807. Flushing cisterns. SHIRES & CO. (LONDON) Ltd. Jan. 19, 1961 [Feb. 11, 1960], No. 4923/60. Class 26. A flushing cistern comprising a main body a and a cover b resting on the rim thereof, has a separate continuous band d of elastic or elastomeric material encircling the cistern to cover the joint between the body a and the cover b, having on its face a short continuous rib e or like projection which seats firmly against the mating-edges of the body a and cover b without forming a seating between them. The mating edges may be slightly rounded or bevelled all round for firmly seating complementary shaped portions of the band d, of semi-circular form on the outer face. The cover b may have a rib c for positioning.
Patent GB-1121986-A (GB)
Title: Scintillation detectors
IPC: G01T1/202
Filed: 1967-02-01
Abstract: A scintillation detector comprises a scintillator in combination with a photo-detector, said scintillator comprising a semi-conducting body of GaAs or a mixed crystal of GaAs and another III-V semi-conductor compound, for receiving incident radiation, X-rays and nuclear radiations for example, and converting same to photons, said photo-detector comprising a semi-conductor photo-detector, preferably a PN junction formed in the same semi-conducting body as the scintillator, for detecting the photons and converting same to electrical signals. Photo-detectors comprising bi-polar transistors and field-effect transistors are instanced. A GaAs crystal may be doped with N-type impurities Te or Se for example, and zinc or cadmium diffused into one end of the crystal to form the P region; for instance, N-doped GaAs may be sealed in a quartz capsule with zinc arsenide and heated at 1000 DEG  C.  To increase absorption of photons in the PN junction photo-detector, the scintillating portion may be GaAs-AlAs or GaAs-GaP (the phosphorus being diffused into the scintillator or included by growing a mixed crystal GaAs1- xPx (x = 0.1 for instance) on the GaAs substrate), or the photo-detecting portion may be overcompensated or may be GaAs-GaSb or GaAs-InAs. The junction may surround the scintillator to reduce photon losses and may be cooled.

Title: Improvements in or relating to a truss structure particularly for aircraft
IPC: B64C3/18
Filed: 1944-03-17
Abstract: 582,527. Joining metal trusses. BUDD MANUFACTURING CO., E. G. March 17, 1944, No. 5008. Convention date, Jan. 28, 1943. [Class 20 (ii)] [Also in Group XXXIII] A trussed frame, more particularly for aircraft structures, in which a first truss member and two substantially aligned transverse members are connected at a joint in the first member, is characterised by the fact that one of the transverse members has a longitudinal element thereof extending through an opening of the first truss member and that a gusset or the like is arranged on one side of the first truss member interconnecting the parts of said member on opposite sides of the opening, the longitudinal element extending through the opening and a longitudinal element of the second transverse member. The invention is shown applied to an aeroplane rudder, comprising a longitudinal spar 11 consisting of upper and lower chord members 40, 41, connected by vertical and diagonal struts 46, 47, a nose portion 14 secured by chords 36a, 36b, in substantial alignment with the upper and lower chords 30, 31, of the transverse rib trusses. The ends of the vertical struts 46 are formed with springs 100, 101, Fig. 6, through which the ends of the nose chords 36a, 36b, project, gusset plates 50, 69, secured to the vertical struts enclosing the chord ends and providing attachments for the ends of the channel-sectioned rib chords 30, 31. The gussets 69 are provided with flanges 70, 71, and 72 for attachment of the spar diagonals 47 and rib diagonals 33, respectively. A gusset plate 61 is secured to the rear surface of the strut 46 to impart resistance to torsional forces.

Title: Improvements in permeability-tuned oscillator tracking arrangement
IPC: H03J3/28
Filed: 1940-03-19
Abstract: 536,505. Wireless receiving apparatus; inductances. JOHNSON LABORATORIES, Inc. March 19, 1940, No. 5099. Convention date, April 10, 1939. [Class 40 (v)] [Also in Group XXXV] To improve tracking in a permeability tuning arrangement for a superheterodyne receiver the signal frequency coil 5 and oscillator coil 18 are constructed as shown in Fig. 2. The coils are mounted on insulating tubes 27 and have identical dust cores 6 simultaneously slidable by means 28. Signal coil 5 is uniformly spaced while oscillator coil 18 comprises closely spaced sections 18a, 18c separated by a loosely spaced section 18b. Section 18a is of the same length as 5 but has fewer turns. Movement of cores 6 tunes signal coil 5 over a range of frequencies and oscillator coil 18 over a narrower range of higher frequencies, to give a constant difference. With the cores withdrawn, alignment is established by means of adjustable condensers (not shown) and, is maintained during the upper portion of the frequency range by the fact that as the inductance of 18a is increasing, the inductance of 18a is decreasing due to withdrawal of the core 6. During the lower part of the frequency range tracking is secured by having the signal core 6 earthed so that the increased capacity with coil 5 accelerates the lowering of the resonant frequency of the signal frequency circuit. Specifications 366,475 and 455,573, [Group XXXVI], are referred to.

Title: Improvements in or relating to bobbin winding machines
IPC: B65H54/12
Filed: 1957-02-19
Abstract: 870,205. Winding bobbins. BRITISH UNITED SHOE MACHINERY CO. Ltd., PRATT, J. W., and ROBERTS, M. Feb. 18, 1958 [Feb. 19, 1957], No. 5527/57. Class 120(2) A bobbin winding machine includes means for rotating a bobbin to wind thread thereon, means for holding a leading end portion of the thread after it has been connected with the bobbin and means acting to cause said portion of the thread to be cut or broken close to the bobbin, during the rotation of the bobbin, as a result of tension applied to it in the winding of the thread round the bobbin. The machine shown comprises a lead 1 mounted on the upper end 3 of a column and having rotatably mounted in it a winding shaft 5 carrying fast and loose pulleys 7 and 9 driven by a belt. Secured on a spindle 21 rotatably mounted in the upper portion of lead 1 is a lever 23 having an arm 25 which at its outer end has secured on it a block 27 having two notches, through one or other of which the thread passes. Should a knot or other irregularity catch in the notch the lever 23 is pivoted and the rope drive is moved from the fast to the loose pulley to stop the machine. The lever 23 has a downwardly extending arm which carries a block 37 arranged to fit closely between the flanges of the bobbin 39 and bear against the thread as it is wound on the bobbin. As the winding proceeds the block 37 is moved outward and when the bobbin is full the belt shaft mechanism is operated to stop the machine. The bobbin 39 has in each flange a relatively small hole one of which is arranged to engage a driving pin 53. Before the bobbin is placed on the shaft 5 the leading end portion of the thread is threaded through the other hole 55 and is thus connected to the bobbin. The bobbin is then placed on the shaft 5 and the thread end clamped in a clamp 57 carried on an arm 63 which is pivoted on a stud 65 for movement towards or away from the bobbin but is normally urged away from the bobbin by a spring 67. When winding commences tension in the thread between the hole 55 and the clamp 57 causes the arm 63 to move towards the bobbin until such movement is arrested by a stop screw 71. This movement allows the thread end to be secured to the bobbin under adequate tension. Further rotation of the bobbin applies increased tension to the thread between the hole 55 and the clamp 57 and this tension together with the pressure on the thread by the edge of the hole 55 causes the thread to be severed or broken close to the bobbin. Specification 806,265 is referred to.
