Title: Air-flow measuring device and method
Inventor: KINGE RICHARD ARTHUR GEORGE
IPC: G01P5/12
Filed: 1985-06-11
Abstract: An air-flow measuring and detecting device or anemometer of the type that operates by the cooling effect of air moving over a heated temperature-dependent resistance 10. The device avoids the need for a second non-heated temperature-dependent resistance for monitoring the air temperature to compensate the system for variations in ambient conditions. This is done by heating the resistance to a temperature sufficiently high e.g. 300 DEG C such that the output of the device is substantially unaffected by variations in static air temperature such as are experienced with changes of atmospheric temperature, e.g. 0 DEG to 50 DEG C. <IMAGE>

Title: Making an optical fibre cable core, with helical fibre containing channels
Inventor: GILL RONALD YAXLEY
IPC: B29C53/14
Filed: 1986-09-17
Abstract: A plastics core (3A) with straight longitudinal channels is extruded around a central strength member, and allowed to cool, and the core assembly is subsequently passed through an induction or a dielectric heater (9) to cause at least the inner region of the core to be softened, the outer part of the core then being rotated around the strength member by means of a pair of oppositely phased reciprocating units (10) and held in that position until cooling of the plastic occurs. The units (10) may each comprise one of a pair of rollers (12, 13) freely or drivingly rotated about an axis transverse to that of the core (3A), and also transversely reciprocated in the opposite phases by rack and pinion drives (23, 24). Alternatively, the reciprocating units may be carried by opposed endless belts (14, Figs. 4 to 6) to simultaneously transport the core (3A), with each unit comprising a core engaging slide block (20), reciprocated from a cam track (21) disposed alongside each belt (14). <IMAGE>
Patent GB-2181613-A (GB)
Title: Switching circuit
Inventor: SELLWOOD RAYMUND ERNEST
IPC: H03K17/10
Filed: 1986-10-06
Abstract: The invention relates to a switching circuit for controlling the application of a d.c. voltage from power supply lines (2,3) to output terminals (4,5), to which a load, such as an armament fuze, is connected. The circuit comprises a number of first transistors (6,7,8) connected in a series string between one power supply line (2) and one output terminal (4), and a number of second transistors (11,12) connected between the junction points (9,10) of the first transistors and the other power supply line (3). A further second transistor (13) is connected between the output terminals. The second transistors are of the opposite conductivity type to the first transistors. When the load is to be energised, switching signals are applied to all of the transistors from secondary windings (16,17,18) of a transistor (14), in response to optical pulses fed to the transformer primary winding (15) over an optical fibre (34). A high-permeability screen (23), located between the primary and second windings as a safety device, must be removed in order to be able to apply the switching signals to the transistors. The switching signals ensure that the second transistors are turned hard off and that the first transistors are conductive for energising the load. In the event of a short-circuit occurring in one of the first transistors when the circuit is quiescent, conduction in that transistor will apply a large forward voltage across the associated second transistor, causing it to conduct heavily. The virtual short-circuit across the d.c. supply will cause a fuse (33) to blow, thereby preventing unwanted energisation of the load. <IMAGE>

Title: Wire mesh truss for wall panels
Inventor: OBATA MASAO
IPC: E04C5/06
Filed: 1986-10-29
Abstract: Upper and lower layers 2,3 of wire are paid out continuously and made into wire meshes 9,10, which are integrated by joining them by support ribs 13,13' while a predetermined spacing is maintained between the two layers. The support ribs are either inclined in mutually opposing directions Fig. 2a, or have their locations staggered in turn, alternately in a direction orthogonal to the longitudinal direction of the wire meshes Fig. 2b. After the resultant solid wire mesh truss is cut to a predetermined length 16, the truss is embedded to a predetermined depth in mortar which fills a molding frame to a prescribed depth; mortar is allowed to cure and harden, the truss with the mortar is removed from the mold and the opposite side of wire mesh truss is provided with mortar in the same manner, thereby sandwiching the truss between the two layers of mortar. Thereafter, a core is inserted to fill the space between the two mortar layers, thereby constructing a lightweight panel. A material such as glass wool having good sound absorbing property and fire-resistance property may be sandwiched between two light-weight panels Fig. 20 and mortar is sprayed onto a joint portion at the construction site to joint mutually adjacent ones of the lightweight panels, thus completing a dividing wall. <IMAGE>

Title: Detection of plug closure in cryogenic pipe freezing by monitoring acoustic emissions
Inventor: BOWEN RICHARD JAMES
IPC: G01N29/14
Filed: 1988-02-08
Abstract: The formation of a plug of frozen fluid within a closed vessel e.g. a pipe 3 during freezing is monitored by means of a sensor 7 disposed outside the vessel. The sensor detects stress waves transmitted in the vessel walls during plug formation and the state of development of the plug is determined from the sensed stress waves. The amplified and filtered signal from the sensor 7 is fed to both display/recording equipment 13, 15, 17 and also to a pulse counter 19 which records the frequency of acoustic emissions from the pipe. The technique is useful in the testing of pipes and vessels containing water-based fluids or oil. <IMAGE>

Title: Metallurgical slag flow inhibitor
Inventor: SCRIVEN RICK R
IPC: B22D43/00
Filed: 1989-01-19
Abstract: For inhibiting the flow of the slag (3) of a molten metal bath through a tap hole (9) of a metallurgical vessel (11). A hollow body (13) has an outer shell (15) which defines an inner chamber (17). The shell has a plurality of passageways (19) spaced substantially evenly about the shell, extending through the shell from the surface of the shell to the chamber. The shell is formed of a heat stable refractory material having a specific gravity which is greater than that of the slag and less than that of the molten metal (7) in the molten metal bath so that the slag flow inhibitor floats at the interface between the molten metal and the slag. The slag flow inhibitor substantially blocks the tap hole of the metallurgical vessel as the molten metal is being poured therefrom so that when the slag flow inhibitor is in position at the tap hole, the molten metal can flow through the passage- ways and chamber to be discharged from the metallurgical vessel through the tap hole prior to any significant amount of slag being able to flow through the tap hole. <IMAGE>
