Title: Power converters with improved switching efficiency
Inventor: SMITH DAVID ANTHONY
IPC: H02M3/335
Filed: 1993-03-17
Abstract: In a converter having a switch 110 for periodically coupling energy to a first magnetic storage means 105 and a rectifier 120 enabling energy stored in the first magnetic storage means 105 to be coupled to the output of the converter during the off period of the switch 110, a circuit 130, 140, 142 reverses the direction of current flow in the rectifier 120 during a time interval just prior to when the rectifier 120 is to be rendered non-conductive. The current reversal substantially reduces or eliminates reverse-recovery currents in the rectifier 120, which may cause short circuits and needlessly dissipates power. The current reversal circuit comprises an energy source 142, a second magnetic storage device 140, and a switch 130. The second magnetic storage device may comprise an inductor 140 or a transformer (405, Figs 8, 9, 10, 12B and 13B). The energy source may include a voltage source 142, the converter's input voltage (Figs 12A, 14B), the output voltage (Figs 6, 8, 14A, 16), or a winding magnetically coupled to another magnetic storage device of the converter (Figs 10, 12B, 13B). The switch 130 may be in the form of a FET (232, Figs 6, 8, 9, 10, 12A-16) and a rectifier (234) or may be a bipolar transistor or an SCR. In a further embodiment the FET rectifier 120 may be replaced by an uncontrolled rectifier (485, Fig 11). An example of a switch control 150 includes a PWM circuit (310, Fig 7A) which generates output control pulses for the switches 110, 120, 130 of the converter via transformers (320, 340). Instead of the direct DC-DC converter of Figs 4, (6, 8, 9, 10, 11, 12A-13B, 15) transformer coupling may be used (Figs 14A, 14B and 16) to provide a DC-AC-DC converter. <IMAGE>

Title: An electrical circuit breaker
Inventor: WILSON MICHAEL JOHN
IPC: H01H83/12
Filed: 1994-02-28
Abstract: An electrical circuit breaker has a relay 20 with contacts 58 carried by contact strips 53 and 54. The contact strips 53 and 54 are attached at one end to an actuator arm 70, which is coupled to a pawl lever 80. The pawl lever 80 carries an armature 89 that is held down by an electromagnet 90 when no fault is detected, power being supplied to the electromagnet 90 only while the contacts 58 are closed. When a fault is detected power to the electromagnet 90 ceases allowing the pawl lever 80 to rotate and the contacts 58 to open in the absence of a manual closing force on the actuator arm 70. To reset the breaker, a rocker arm (100, Fig 5) is rotated manually in one direction to push down the actuator am 70 which causes the pawl lever 80 to move towards the electromagnet 90 and the contacts 58 to close whereupon the electromagnet 90 is energised. The breaker can be tested by rotating the rocker arm (100) in the opposite direction. <IMAGE>

Patent GB-2315078-A (GB)
Title: Moulding tools
Inventor: BLAKE MICHAEL JOHN
IPC: B29C33/02
Filed: 1996-07-06
Abstract: Moulding tools are produced by casting from a master model a mandrel composed of a dimensionally stable ceramic material such as DENSIT #, embedding heating elements in the mandrel, and then depositing a coating of a metal such a nickel on the mandrel preferably by vapour deposition. Since a heat control means is incorporated this eliminates the need to produce a shell in a separate stage. The mandrel serves not only to define the shape of the working surface of the finished tool, but also to support the working surface when the tool is in use. The resultant coating can be further worked to modify its surface. The metal coating may be deposited by chemical vapour deposition or electrolytically and is preferably nickel.
