Title: A system for communication with a machine
Inventor: KIT-FUN HO
IPC: G10L21/013
Filed: 1985-10-17
Abstract: Musical intervals are used as codes to communicate preselected commands or inputs to a computer. The system can use the human voice, sounding notes (DO-RE, etc.) successively to establish the interval and can use electrical circuitry and programs for converting the received notes or tones into pulse trains of the same fundamental period and for storing and calculating the period and interval. When a particular interval is received the apparatus including a digital micro-computer may execute a pre-set recorded subroutine and restore the circuitry for the reception of a second interval. <IMAGE>

Title: Reservoir management process
Inventor: NICHOLSON ROBERT DOUGLAS
IPC: E03B3/00
Filed: 1986-05-09

Patent GB-2194400-A (GB)
Title: Starter & discharge lamp including it
Inventor: ASHWORTH STEPHEN KENNETH
IPC: H05B41/04
Filed: 1987-07-17
Abstract: A starter for a gas discharge tube (1), (Fig. 1), includes a fluoractor 11 which conducts a current to heat the electrodes (2, 3) of the tube (1) and switches off to cause a high voltage to be induced across the tube by a ballast inductor (5) to ignite it. Multiple triggering means (DC1, C2, R6) is operable to trigger fluoractor 11 into its conducting and non-conducting state at least twice during a half cycle of applied alternating voltage. When a main switch (10) is initially closed, the triggering means DC1 turns the fluoractor 11 on to pass electrode heating current until a capacitor C1 has charged to a level at which the impedance of a thyristor SCR1 has reduced sufficiently to cause fluoractor 11 to turn off and generate an ignition pulse on the trailing portion of a main half cycle. This action is repeated to generate one ignition pulse per half cycle for a few half cycles. The decreased impedance of thyristor SCR1 due to the gradual build up of charge on capacitor C1 then causes fluoractor 11 to turn off on the leading portion of each half cycle whereupon the multiple triggering means DC1, C2, R6 becomes effective to cause the fluoractor to generate multiple ignition pulses (e.g. three or four) in each half cycle. Multiple triggering during the first half of each half cycle allows the maximum current to flow through the tube before the supply polarity reverses. If the tube does not ignite, build up of charge on capacitor C1 causes the gate of fluoractor 11 to be clamped to ground line 18 to prevent it being turned on. A resistor R5 provides a potential source for capacitor C1 when fluoractor 11 is off to ensure that the impedance of thyristor SCR1 is held low inhibiting further operation of the starter. A zener diode 202 in series with resistor R5 reduces problems of residual voltages which-may prevent capacitor C1 discharging when the main switch (10) is off. Residual charge on capacitor C1 would reduce the preheat time. <IMAGE>

Title: Apparatus for assembling circuit components
Inventor: JACKSON WILLIAM EWART
IPC: H05K13/04
Filed: 1987-12-22
Abstract: The apparatus has a pick-up tool 6 supported at one end of a horizontally extending support arm 12. The support arm is mounted for horizontal sliding movement relative to a cup-shaped support member 14 eccentrically mounted relative to a rotatable boss 20. The boss is journalled for rotation about a fixed vertical support spindle 24. Reciprocation of the arm 12 and rotation of the cup-shaped support member 14 enables the pick-up tool 6 to be moved along a linear path for positioning components on a printed circuit board. The pick-up-tool 6 is connected to a vacuum source so that its nozzle 8 can pick up a circuit component from a turnable 36. The tool is then moved to position the component relative to the circuit board and the vacuum released to deposit the component on the circuit board. <IMAGE>

Title: Connecting tubular components
Inventor: TURNER WILLIAM ALAN
IPC: F16L37/00
Filed: 1988-02-04
Abstract: Apparatus for the temporary connection of tubular components, for example for use in the remote submerged connection of large diameter platform leg sections, comprises a collar 5 which is fixed permanently or temporarily to one tubular component 2, surrounds the end portion 2a of that component and extends beyond the end of the component to surround the end portion 1a of the other component 1. The collar 5 carries force applying means comprising cylinders and pistons 8 carrying wedges 11 for applying axially and radially directed forces to the end portions of the other components in a direction to bring the end portions of the components together and to correct any axial misalignment insofar as is possible or necessary. When the sections have been brought together, a tubular element 3 is inserted to overlie the junction therebetween and grout is introduced into the gap between the element 3 and the sections. When the grout has set the force applied by the cylinders and pistons 8 is relieved and the shell 5 may, if removable, be removed. In a modification (figure 5) the element 3 is used to temporarily connect the sections together and is provided with means for engaging the sections to either side of the junction therebetween. <IMAGE>
