Title: Corrugated roofing panel
Inventor: SAIVOSALMI RISTO
IPC: E04D3/365
Filed: 1989-12-15
Abstract: A roof slab, which is manufactured preferably of plastic coated steel sheet by roll-forming a plane sheet web first to be corrugated and by pressing subsequently transverse steps in the corrugated sheet web, thus providing a tile-like structure in the roof slab.

Patent GB-2249356-A (GB)
Title: Shroud liner
Inventor: LEONARD JOHN FREDERICK
IPC: F01D11/08
Filed: 1990-11-01
Abstract: A shroud liner 5 has a hooked downstream end passing between a stator vane portion 3A and a casing portion 1A so that in operation the gas loads on the vane 3 cause the liner to be held between the vane and the casing 1. The shroud liner 5 also has a resilient upstream end portion 5B fitting between a second stator vane 4 and the casing 1 so that in operation gas loads on the vane 4 cause it to move towards the casing, compressing the shroud liner 5. As a result the shroud liner is securely held in place at its downstream end, but can slide relative to the casing and vanes at its upstream end to allow for thermal expansion. <IMAGE>

Patent GB-908893-A (GB)
IPC: G01M1/22
Abstract: 908,893. Measuring rotor unbalance electrically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 21, 1959 [May 2, 1958], No. 14110/58. Class 40 (1). [Also in Group XXXVI] The phase of the unbalance voltage from a rotor is determined by comparing it with the output from a synchronous selsyn whose stator is rotated through a measured angle until the two voltages are in quadrature. As shown (Fig. 1), a rotor 1 is driven by a motor 4 which also drives a selsyn transmitter 6 having 3-phase stator and 3-phase rotor windings. Initially, two of the stator windings are fed with D.C. via switch 7<SP>1</SP>, and the synchronous A.C. voltages developed in the rotor windings are fed to the rotor windings of a receiving selsyn 8. The A.C. voltage from two stator windings of selsyn 8 is phase compared at 13 with the voltage derived from a vibration pick-up 10 (or 11) at the bearings 2 carrying test rotor 1, any divergence from 90 degrees phase difference producing an output signal which, after amplification at 14, energizes motor 15 to displace the rotor of selsyn 8 until the two voltages are exactly in quadrature. Motor 4 is then deenergized by operating switches 7, 9 and the stators of selsyns 6, 8 are fed with 3-phase A.C., plus D.C. in one phase by rectifier 28, when the rotor of selsyn 6 aligns itself with the rotor of selsyn 8, simultaneously rotating the shaft 1 to the appropriate angular position for the removal of the unbalance at the bearing plane containing pick-up 10 (or 11). To determine the magnitude of the unbalance signal, it is fed through amplifier 16 to a thermal filter 17, where it is compared with the output signal from the stator of selsyn 8 after being fed through a choke 18 to bring the two currents into phase, the D.C. output from filter 17 being proportional to the fundamental component of the voltage from pick up 10 (or 11). This is automatically balanced against a voltage tapped off from a D.C.-fed potentiometer, a second ganged wiper lighting a lamp indicating the digital magnitude of the unbalance.

Patent GB-2254429-A (GB)
Title: Liquid level sensor
Inventor: BIRT L A
IPC: G01F23/24
Filed: 1991-04-04
Abstract: The liquid level circuit comprises two or more probes PR1, PR2 and a sensing circuit, the oscillation frequency of which is altered when the probes contact the liquid. The probes are electrically isolated from the circuit and connected across the secondary winding S2 of a transformer T1. The primary winding P1 of the transformer T1 forms a part of a tuned circuit 10 which oscillates at its resonant frequency except when the probes PR1, PR2 are immersed in the liquid 11: in the latter case the load impedance of the transformer T1 is altered and this causes a change in the frequency of oscillation, e.g. a cessation of oscillation. This change in oscillation is detected by an output circuit which delivers a DC output signal. <IMAGE>

Title: Method of construction of marine hull
Inventor: KELSALL DEREK HAMMERSLEY
IPC: B63B5/24
Filed: 1993-03-04
Abstract: A marine hull of sandwich construction is constructed from a single flat panel on which the subsequent bending and culling is marked out while still flat. The panel is first bunt to a constant section, comprising bottom panel 4, radiussed chine 5 and topside panels 6. The bent panel is then cut and sections removed (Figs 4 and 5, not shown) and the cut edges joined to form the hull. The shaping, by cutting away and cutting into and the bending of that constant section is done in such a way that most of the time consuming tasks normally associated with such construction are eliminated. i.e. without the need for the usual framing, measuring, setting up and assembly of numerous pieces associated with other one-off methods. The hull is completed after shaping by adding the remaining material required to nest the scantling specification to the skins. The invention particularly applies to "radiussed chine" hulls, consisting of topsides, bottom panel and radiussed chine between. <IMAGE>
