Title: Cleaning circuit boards with hydrogen
Inventor: KHO YUE SERN
IPC: C23G5/00
Filed: 1993-01-13
Abstract: A method of cleaning the metal surfaces of an electric circuit board, such as a printed circuit board (PCB), by removing metal oxides therefrom comprises directing diatomic hydrogen onto the surface of the PCB to be cleaned. The hydrogen reacts with metal oxide on the metal surfaces of the PCB to form metal, thereby effectively removing the oxide layer and cleaning the metal surfaces. The cleaned PCB is then introduced to a flow or wave soldering machine. The cleaned PCB may be coated with a mild acidic flux to prevent re-oxidisation of the metal surface prior to soldering. An apparatus for carrying out this method comprises an elongate chamber 1 comprising a hydrogen generator 3, a gas storage tank 4, a sprayer mechanism and a conveyor system 6, positioned adjacent a conventional soldering machine 2. The sprayer mechanism is formed with a plurality of outlets for the hydrogen distributed along its length and directed upwards. This mechanism is mounted on a carriage which moves back and forth along the length of the chamber 1. The conveyor system 6 comprises two elongate rails 17 which extend along sides of the top surface of 1.A jig 18, on which the PCB 19 is mounted, has free ends which are received by rails 17. <IMAGE>

Title: Reduced noise controller for a switched reluctance machine using active noise cancellation
Inventor: RANDALL STEVEN PAUL
IPC: H02P25/08
Filed: 1996-08-29
Abstract: A reduced vibration and reduced noise controller for a switched reluctance machine system has a circuit 44a-c that monitors firing signals which are used to energize a phase winding in the switched reluctance machine over an angular period of rotor rotation. When the firing signals indicate that a predefined switching event, causing a change in flux, has occurred, one or more timed voltage pulses (60, Fig 6) are applied to the phase winding at predetermined points in time following the predefined switching event. The timed voltage pulses induce vibration forces in a motor which actively cancel unwanted vibrations in the motor system, thus reducing unwanted vibrations and acoustic noise. The machine may be a rotary or linear motor or generator. Details of the controller circuit 44 are described (Figs 12 and 13).

Title: A tangential flow separator with inner settlement chamber
Inventor: TODKILL PATRICK
IPC: B01D21/00
Filed: 1996-09-19
Abstract: A tangential flow separator comprises a substantially cylindrical outer separation chamber, an inlet 25 tangential to the wall of the separation chamber causing heavier and lighter entrained particles to separate out from the fluid under a centrifugal force, arrows A, C, a concentric inner settlement chamber and a central clean fluid outlet conduit from the inner settlement chamber passing through both chambers along their common axis. Particles still entrained in the fluid entering the inner settlement chamber can settle out under the now predominant force of gravity due to the decreased angular velocity. Placing the central outlet conduit orifices away from the central axis ensures particles are not extracted by virtue of being purely in a low angular velocity under no centrifugal forces. A baffle (47, fig 1b) may be provided to break up any cyclonic flow entering the settlement chamber 42. The apparatus may be only single ended (fig 1) or for gaseous carrier flow.

Title: Shaft support and bearing arrangement for ducted fan engine
Inventor: FREEMAN CHRISTOPHER
IPC: F16C19/26
Filed: 1996-12-20
Abstract: A ducted fan gas turbine engine (10)(fig. 1) is provided with a fan (12) which is carried by a shaft 16 supported by a bearing 19. A frangible fuse ring 29 secures a bearing support 21 to a fixed structure 22 to maintain the shaft 16 carrying the fan (12) coaxial with the engine longitudinal axis 15. In the event of severe fan damage, the fuse ring 29 fractures to allow the fan shaft 16 to orbit about the engine longitudinal axis 15. A pair of threaded members 39,41, (one of which 41 has a variable diameter thread) cooperate as a result of the orbiting motion so that one of the members 39 is moved axially to exert radial forces on the bearing support 21 to restore the coaxial relationship between the fan shaft 16 and the engine longitudinal axis 15 once the shaft has slowed to windmilling speed.
