Patent GB-2256086-A (GB)
Title: Apparatus for producing pulses of charged particles.
Inventor: SHOULDERS KENNETH R
IPC: H01J11/00
Filed: 1992-06-30
Abstract: Pulse generators are described which comprise a charged particle emitting electrode 604 having a pointed end wefted with electrically conducting liquid; a solid dielectric member 606 having a tip with a pointed opening downstream of the pointed end; and an accelerating electrode 610 on an exterior wall of the dielectric member removed from the opening in the pointed tip; an extractor electrode 612; and an output electrode 622. The accelerating electrode is at a voltage relative to the source and is positioned so that charged particles emitted by the charged particle emitting electrode selectively propagate to the accelerating electrode via a path (a) through the opening and (b) that is reversed in direction after the charged particles pass through the opening. The extractor electrode is positioned downstream of the opening and is at a higher potential than the accelerating electrode, so that only certain of the charged particles emitted by the emitting electrode are incident thereon and others of the charged particles emitted by the emitting electrode are incident on the accelerating electrode. The output electrode is capacitively coupled with the extractor electrode for deriving pulses in response to the charged particles being incident on the extractor electrode. <IMAGE>

Title: A multiprogram processor having multiple program counters
Inventor: WHITMORE BRIAN EDWARD
IPC: G06F9/32
Filed: 1994-03-02
Abstract: A microprocessor, microcomputer, microcontroller or similar device has more than one program counter with each program counter able to sequence through its own section of the program Each of the program counters and hence its associated program section can respond differently to an applied interrupt. The clock pulses applied to the program counters can be at different respective rates and are applied so that only one program counter receives a clock pulse at any one time. That program counter receiving the clock pulse has control, via a memory manager and address bus interface unit, over the address bus and hence access to the data bus and other normally common functions such as timers and the central processing unit although these units can still be performing operations initialised by the other program counters when they had access to these units. <IMAGE>

Title: Inclination adjustment means for an arm of a loudspeaker support
Inventor: WOODS RICHARD PAUL
IPC: A47B96/07
Filed: 1995-09-27
Abstract: A support bracket for a loudspeaker has an arm (27) mounted for pivotal upwards and downwards movement by means of a cylindrical pivot member (28) fitted between opposite sides (29, 30) of a plate metal housing part (11). The pivot member has a threaded bore therethrough in which is threadedly engaged a shaft (19) provided with a screw-thread (22), a thumb-wheel (26) on the shaft being rotatable to cause rotation of the shaft. As the shaft is otherwise held captive between upper and lower walls of the housing part (11) rotation of the shaft causes the pivot member to move along the shaft. Accordingly the angle of inclination of the arm member relative to the upper wall (12) of the housing can be varied, with a stop (31) at the upper end of the arm member engaging said upper wall. <IMAGE>
