Title: Method of and equipment for controlling an engine fuel supply system
Inventor: GRONENBERG ROLAND
IPC: F02D41/20
Filed: 1992-06-19
Abstract: A method of controlling an engine fuel supply system controlled by an electromagnetic valve comprises calculating a switch-on instant (E) and/or a switch-off instant (A) for the valve starting from a fuel conveying start rotational angle (WB) and a fuel conveying duration swept angle (WD) subject to consideration of the switching times of the valve, the switching times being taken into consideration in the form of a switching angle (WTA). Fluctuations in the switching times can thereby be minimised. <IMAGE>

Title: A compressor surge control system.
Inventor: WALKER JAKE
IPC: F02B37/18
Filed: 1992-06-24
Abstract: The compressor 18 of a turbocharger system has an inlet 16 with an inlet pressure sensor 54 and an outlet 18 with an outlet pressure sensor 56. An air flow sensor 58 measures the airflow in the outlet 17. A relief pipe 52 and relief (recirculation) valve 50 are provided to recirculate air from the output 17 to the input 16. The relief valve 50 is controlled by a control unit 60 which operates in response to the sensors. Under conditions of low air flow rate and high pressure ratio, the valve 50 is opened to increase the actual air flow through the compressor 18 to eliminate compressor surge. <IMAGE>

Title: "improvements relating to fishing lines"
Inventor: BURGESS PAUL DAVID
IPC: D07B5/00
Filed: 1992-07-06
Abstract: A fishing line has a core within a water impermeable sheath. The core is inextensible, or virtually so, while the sheath is capable of stretching. The core is longer than the sheath in its relaxed state and the two components are attached at the extreme ends of the line so that the core is slack within the sheath. Thus the line can stretch according to the characteristics of the sheath up to the point when the core becomes taut. The core may be threaded through the sheath using a magnetic leader element.

Title: Microprocessor having a run/stop pin for accessing an idle mode
Inventor: DREYER ROBERT S
IPC: G06F11/36
Filed: 1992-08-28
Abstract: A Run/Stop (R/S) pin 12 on a microprocessor chip is asserted to access and hold an idle mode. An additional pin, "acknowledge pin" 16, is provided to indicate when the microprocessor is in the idle state. The idle mode is asserted at an instruction boundary that is, when the execution unit 22 has completed all its modifications of registers, flags, and memory for a first instruction, but before it begins execution of the next instruction following in the pipeline. In the idle mode, the decoder 18 does not issue instructions into the pipeline, but the clock operates normally and other microprocessor functions are operable. A port 40 may be provided, with a secondary control unit 42 for issuing simple instructions directly to the execution unit, bypassing the normal instruction issue process. The present invention can be useful for implementing debugging and remote diagnostic systems, and also for synchronizing microprocessors running in parallel. <IMAGE>

Patent GB-2285139-A (GB)
Title: Testing electronic devices
Inventor: LAW YIU KAM
IPC: G01R31/28
Filed: 1993-11-25
Abstract: A method for testing electronic devices attached to a leadframe includes positioning more than one electronic device (42, 44, 46) attached to a common leadframe underneath a test fixture (50). The test fixture (50) then contacts the devices (42, 44, 46) to perform an electrical test. Testing more than one device at a time while they are attached to a common leadframe greatly improves efficiency of the testing process. Furthermore, positioning the devices (42, 44, 46) below the test fixture (50) reduces the amount of contamination that may settle on the test fixture. The leadframes may be transported by a walking beam 36 between storage areas 30, 64. <IMAGE>

Title: Cache lock-out
Inventor: PHILLIPS IAN
IPC: G06F12/0802
Filed: 1993-12-01
Abstract: In a data processing system utilising fast-access cache memory, data words written in to the cache from main memory are immediately read and checked against the original, any discrepancies resulting in the lock-out of that cache location so that next time the processor calls up that data word it is again read from main memory and is written into another location in cache. The system is thereby tolerant of defective cache locations. <IMAGE>

Title: Method of and apparatus for manufacturing various kinds of gases to be supplied to semiconductor manufacturing factories
Inventor: HATA YUICHI
IPC: H01L21/673
Filed: 1994-04-22
Abstract: A method of and an apparatus for manufacturing high-purity air and various kinds of gases obtained by using air as a raw material which are used for semiconductor manufacturing industries, which method and apparatus are capable of providing as products high-purity air, high-purity nitrogen and oxygen-enriched air at once. Raw air is compressed to 3-10 Kg/cm<2>G and introduced into a catalyst tower (8), and the carbon monoxide, hydrocarbons and hydrogen in the raw air are converted into carbon dioxide and water. The catalyst-reacted temperature-increased air is cooled and then introduced into adsorption towers (12a, 12b) in which carbon dioxide, water and other impurities are adsorption-removed. A part of the refined air obtained is drawn out as high-purity product air, and the remaining part thereof is introduced into a primary heat exchanger (18) and cooled substantially to a liquefication temperature. The resultant air is introduced into a simple rectification tower (19) and subjected to liquefication rectification, and high-purity nitrogen is drawn out from the top portion of the tower (19) and extracted as a product through the primary heat exchanger (18). Meanwhile oxygen-enriched liquefied air is drawn out from the bottom portion of the simple rectification tower (19), introduced into a condensation evaporator (24), gasified, drawn out therefrom, introduced into the primary heat exchanger (18), and subjected to a temperature increasing operation. After the temperature of the gas has reached to an intermediate level, the gas is drawn out and introduced into an expansion turbine (35), in which the gas is expanded and cooled to generate cold. After the cold has recovered, it is extracted as refined oxygen-enriched air. <IMAGE>

Title: Automatic wear adjustment in a friction clutch for a motor vehicle
Inventor: WEIDINGER REINHOLD
IPC: F16D13/58
Filed: 1995-11-09
Abstract: A friction clutch (1) has a rotatable flywheel (2), a pressure plate (5) rotatable with the flywheel but axially displaceable, a clutch plate carrying friction linings (11) between the pressure plate (5) and the flywheel (2) and a diaphragm spring (6) or plate spring providing an actuating force urging the pressure plate towards the flywheel. The clutch also has a release device for the pressure plate (5) and an automatic adjuster (10) for adjusting the position of the spring (6) in dependence on the wear of the friction linings (11). The amount of adjustment of the spring position is variable, and compensates only partly for the wear of the linings (11), to ensure that the actuating force acting on the linings (11) is such as to give the clutch a constant torque transmission capability throughout its working life. The adjuster (10) comprises a ring element (16) with inclined surfaces (17) engaging opposing surfaces (18) on the pressure plate (5), and means (13) engaging a profile (20) in a recess (19) in the ring element (16). <IMAGE>
