Title: Method of and apparatus for cleaning fibres
Inventor: BISCHOFBERGER ULRICH
IPC: C03B37/00
Filed: 1992-08-20
Abstract: Mineral fibres are separated from non-fibrous contaminants by suspending them in a liquid or gaseous carrier which is then flowed across one side of a cross-flow filter 3 having elongated apertures oriented in the flow direction to allow the fibres through. The fibres are collected by a downstream filter 7, from which the carrier is recycled. <IMAGE>

Title: Microprocessor 2X core design
Inventor: CONARY JAMES W
IPC: G06F12/08
Filed: 1992-08-28
Abstract: A microprocessor that operates at the speed of the bus or at a speed which is a multiple of the bus speed on a selectable basis is disclosed. The microprocessor includes a phase locked loop 300 to generate clock signals for operations within the microprocessor PH2, PH1 and bus clock signals for data transfer operations on the bus CLKIN, CLKOUT. The present invention allows a microprocessor core to operate at the same frequency or twice the frequency of the address/data buses. Thus, during the manipulation of arithmetic operations which require multiple cycles to complete, the higher frequency of the core clock allows these types of operations to be complete in less time. therefore, reducing the time in which the bus is idle. <IMAGE>

Patent GB-2271721-A (GB)
Title: Suction system
Inventor: DEVLIN THOMAS
IPC: A61M1/00
Filed: 1993-10-11
Abstract: A medico-surgical suction system has a container 1 with an outlet 10 connected to a vacuum pump 2, and an inlet 11 connected to a suction catheter 3 via a dual-lumen tube assembly 4 one end of which is connected to the container 1 and the other end of which has a suction control 43 and a coupling 45 for the catheter. A valve located in the outlet 10 of the container 1 is connected to the suction control 43 via a minor lumen of the tube 4. A side lumen enables the vacuum pump 2 to apply reduced pressure to one end of the valve which holds the valve off against the action of a spring. Actuating the suction control 43 allows air to flow to the valve via the minor lumen so that the effect of the reduced pressure is overcome and the spring opens the valve, thereby applying suction to the catheter 3. By locating the valve remotely of its control 43, there is no risk that leakage from the valve will contaminate the user. The location of the valve and the type of valve and hand control employed is varied in other embodiments. <IMAGE>

Title: Electrical surge protector for signal lines
Inventor: BRAITHWAITE IAN
IPC: H01Q1/50
Filed: 1996-06-21
Abstract: Signal transmission lines operating at frequencies from 1MHz to several hundred MHz are protected against surges, eg. due to lightning, by means of a surge protector incorporating one or more chokes 16 having a saturating magnetic core, particularly a ferrite core. The choke presents a high shunt impedance to the high frequency signals. The frequency components of a surge are at lower frequencies at which the choke 16 will saturate at relatively low currents (tens of amps) to present a low impedance to the surge. Such a choke (30, Fig.9) may be used by itself as a surge protector, eg. connected between the inner conductor and shield of a coaxial cable. Alternatively, one or more saturating core chokes 16 may be connected in series with a surge protection device 22 which would otherwise divert wanted signal current due to low capacitive reactance at the signal frequencies. Such a surge protector may be in the form of a transient suppression diode 22 together with steering diodes. A gas discharge tube 20 may be provided as an additional surge protector.
