Title: Microcomputer system incorporating a cache subsystem using posted writes
Inventor: BEGUN RALPH MURRAY
IPC: G06F12/08
Filed: 1989-03-03
Abstract: A microcomputer system includes a microprocessor, a cache memroy, and a cache controller all coupled to a local bus. The local bus is coupled to a sytem bus, connecting the remaining system components, through latches. When writing data, the microcomputer can perform a posted write to a unit on the system bus by writing the data into the latches and then, on receipt of a ready signal from the cache controller, continuing its operations without waiting for the data to pas to its destination. A problem arises if the data is posted to a unit with a data width less than that of the microprocessor. In this case, the data should be sent in multiple cycles, but the read signal is generated before the data width of the unit is known and the microprocessor then continues its operations and can not, therefore, transmit the data correctly. To solve this problem, a logic unit is added to monitor the ready signal and the output of a decoder which detects non-cacheable addresses (which are of data width different from the microprocessor data width). If a non-cacheable address is detected, the read signal from the cache controller through the logic unit is withheld from the microprocessor, which now waits to continue processing beyond the write until a ready signal is received from the addressed unit on the system bus.

Title: Aircraft wheels with rotating means
Inventor: COXHEAD STANLEY ALBERT
IPC: B64C25/40
Filed: 1989-06-02
Abstract: A series of vanes (several alternative designs are described) each vane being mounted upon a simple rotating axis upon an aircraft wheel or attached trim, which will automatically open at the lower 180 degrees part of an aircraft wheel and automatically close at the upper 180 degrees part of the wheel under the influence of the slipstream, and which will cause a greater air resistance on the bottom half of the aircraft wheel and a much smaller resistance at the top half of the wheel. This will cause the aircraft wheel to rotate in sympathetic motion to the aircraft flight when landing upon the runway and greatly reduce or eliminate the burn and friction suffered by an aircraft's tyres when first in contact with the runway, and also assist in a smoother landing for the aircraft. <IMAGE>

Title: SiC fibres
Inventor: SIDKY PAULETTE SHAFIK
IPC: C01B31/36
Filed: 1989-07-28
Abstract: Fibres are made by the process of infiltration of carbon fibres by liquid silicon. Silicon (12) is liquefied in a silicon nitride crucible (13) provided in its base with a fine hole 14 for passage of a carbon filament (10). The hole (14) is fine enough such that surface tension force retains the liquid silicon within the crucible. The crucible is heated by means of an induction furnace to a temperature of about 1575 DEG C, well above the melting point of silicon. The carbon fibre is then drawn through the melt, the speed of movement determining the amount of silicon loading of the filament. <IMAGE>

Title: Vibrating element apparatus for fluid density and/or viscosity determination
Inventor: LIMITED GEC-MARCONI
IPC: G01N11/16
Filed: 1989-10-05
Abstract: Sensor apparatus which may be used for measuring the density and/or viscosity of, for example, frying oils includes two stainless steel tubes 1, 2 closed by caps 3, 4 and fixed to a diaphragm 5, the tubes being immersed in the fluid. An alternating voltage is applied to one of a pair piezoelectric transducers 9, 10 to produce oscillations of the tubes and their vibration is monitored by the other transducer. The difference in phase between the driving voltage and the detected vibration may be used to determine the viscosity of fluid. The tubes are vibrated at varying frequencies, preferably at frequencies above and below the resonant frequency when the tubes are submerged. Different signal processing is adopted if the fluid is of high viscosity and here the resonant frequency and damping constant are derived. <IMAGE>

Title: Soft-release wrap-spring brake mechanism with oil-impregnated powerdered metal drum.
Inventor: PERISHO RANDAL J
IPC: B60T7/10
Filed: 1992-12-16
Abstract: The mechanism, eg in a vehicle parking brake, includes a cylindrical drum (26) about which is concentrically arranged a helical clutch or brake spring (30), the coil turns of which are normally contracted radially inwardly into frictional engagement with the outer periphery of the drum. The drum 26 is formed of powdered metal impregnated with damping oil. Owing to the direction of the coil turns, the drum may be rotated only in a first direction relative to the spring, and upon radial outward expansion of the spring, the viscous film of the dampening oil between the outer periphery of the spring affords controlled soft-release of the drum for rotation in the opposite direction. The drum may be formed from elemental iron and nickel powder, with graphite and copper powder; the oil may be a polyalphaolefin. <IMAGE>

Title: Releasable  bolt keep
Inventor: FRY BRODIE
IPC: E05B15/02
Filed: 1993-07-03
Abstract: A bolt keeper comprising two main elements hinged about a common point and held closed by a ridge and groove coupling.
