Title: High voltage transformer connector bushing
Inventor: THOMAS ALASTAIR WILIAM RICTCHI
IPC: H01F27/04
Filed: 1992-02-03
Abstract: A recessed support unit (12) for enabling electrical connection of, for example, a ring main unit to high voltage windings of a transformer housed in a casing, has a housing (44) of electrically insulating material. The housing of generally rectangular cross-section and has several pin connectors (18) sealingly extending through a base wall (17). The inner end (32) of each pin carries a number of spring biased blades (23) which engage with connector pins (21) of the ring main unit. The connector pins project through an open end of the housing (44) which lies opposite the base wall (17). The open end has a peripheral flange (13) by means of which the recessed support unit (12) is secured in a recess (11) in the wall of the transformer casing. The ring main unit is supported against the open end of the support unit (12) by mounting on studs (15) secured to the transformer casing. It is therefore a simple matter to change the ring main unit simply by undoing retaining nuts and moving the ring main unit away from the side wall of the transformer casing. There is no need partially to drain insulating oil from the transformer casing. <IMAGE>

Title: Controller for a microwave oven
Inventor: KIM BAE-JIN
IPC: H05B6/68
Filed: 1995-08-21
Abstract: The controller has a microcomputer 90 which controls the microwave oven according to the mode of operation selected by a switch module 75 to which periodic scan signals SCN1 - SCN4 of different phases are applied. If one or more of the switches SW1 - SW4 is in an input mode, a corresponding one of the scan signals, or a logically ORed combination of corresponding scan signals, appears at a LATCH output of microcomputer 90 and is also applied via a node A to vary the charge on a capacitor 72 causing a transistor 69 to turn on. Another transistor 78 is thereby caused to turn on to latch transistor 69 on. After a first time delay the LATCH output is held continuously low, and after a further time delay a low signal appears at a power control output PWR of the microcomputer 90. Transistors 65 and 69 are thus both on so that a relay 62 is energised to supply power to a magnetron 19, provided that a door switch 61 (in series with the relay 62) is closed. The PWR output is pulsed during a programmed heating period to turn transistor 65 and relay 62 on periodically. At the end of the heating period, the LATCH and PWR outputs are both held high to turn off transistors 65, 69 and thus relay 62 and magnetron 19. <IMAGE>

Patent GB-2308361-A (GB)
Title: Improved optical fibre cleaver
Inventor: MYERS DAVID LISTER
IPC: G02B6/25
Filed: 1995-12-19
Abstract: An optical fibre cleaver 10 has location means 11 for an end of an optical fibre. The cleaver 10 also includes a clamping means 13 and a tensioned clamping means 14, as well as having a curved anvil 15 and a diamond blade 16. The clamping means 14 is tensioned so that such clamping means 14 is attempting to move away from the diamond blade 16. The cleaver also has an operating means 17 which is operated by pushing downwardly thereon. Once the fibre 12 has been clamped in position then the operating means 17 is operated and the diamond blade 16 is brought down towards the anvil 15 and nicks the fibre 12, the fibre breaking off by the tensioned clamping means 14 moving away from the diamond blade 15. In such position of use, the operating means 17 returns to its original position and, in so doing, causes member 18 to move downwardly via linkage 19. Such downward movement of member 18 contacts the end region of the fibre offcut and by continuing its downward movement causes said offcut 21 to be forced into the container 20 acting as a sharps bin located in the cleaver 10. Upward movement of the operating means 17 permits the cut end of the optical fibre to be removed.
