Title: Universal solid state power controller
Inventor: MCCOLLUM PATRICK E
IPC: H03K17/08
Filed: 1987-07-06
Abstract: A universal solid state power controller for controlling the application of a source voltage to a load comprising a semiconductor switch having a predetermined non-bounce switching characteristic. The switch is responsive to an operating signal for connecting the load to the source voltage. A control means has a microcomputer following a predetermined program. The control means is responsive to a command electrical signal and provides the semiconductor switching means operating signal. The microcomputer program has an ac subprogram for SSPC operation with a source voltage of sinusoidal character and a dc subprogram for SSPC operation with a source voltage of direct current character. A voltage selection circuit provides a logic signal of a first polarity to the microcomputer to direct the microcomputer to use the ac subprogram for SSPC operation with an ac source. The logic signal has a second polarity to direct the microcomputer to use the SSPC dc subprogram for operation with a dc source. A current rating selection circuit provides a logic signal to the microcomputer to direct the microcomputer to select a predetermined current rating for the power controller. The invention electrical switch provides a bounce-free closure of the conduction path from the alternating source voltage to the load in response to the command electrical signal. The closure corresponds with a first predetermined sequence of alternating source voltage crossing zero voltage. The invention switch interrupts the conductive path to the load without contact bounce, associated arcing in response to interruption of the command electrical signal.

Abstract: Liquid discharge apparatus, whereby passage of liquid from a source e.g. a fuel tanker to a destination e.g. fuel storage vessel and stand pipe (34) may be prevented when the source is connected to an unsuitable destination having regard to the type of liquid at the source, includes an outlet valve (10) on the liquid source, a pipe (30) connectable to the valve, and a lock (24) which enables the valve (10) to be opened only by presentation to the lock (24) of a key (43) corresponding to a liquid associated with that source and releasable from the destination only in connection of the other end of the pipe thereto. The corresponding key will be inserted through an aperture (20) in a fixed plate (12) and a matching keyway in a rotatable plate (18) to actuate the lock and open the valve. Loading of the source via the valve with a different liquid can only take place when the plate (18) has been rotated so that a pin on the loading means and passing through a respective aperture (14) in the fixed plate can also pass through an aperture in the rotary plate. When this occurs another, different keyway will be aligned with the aperture (20) and the lock. <IMAGE>

Patent GB-2226671-A (GB)
Title: Vehicle intruder detecting apparatus
Inventor: CUNNANE PAUL ANDREW
IPC: B60R25/10
Filed: 1989-10-13
Abstract: The apparatus comprises a circuit controlled by a microcontroller (16 Fig. 1, not shown). The circuit comprises a voltage drop detector circuit 18 for detecting a voltage drop in the battery of the vehicle. The circuit 18 comprises an AC amplifier 40 coupled to the positive terminal of the battery through a coupling capacitor C10 and a resistor R9 and a terminal 3. The output from the amplifier is fed into one input 43 of a voltage comparator 44. A reference voltage derived across a potential divider R16 and 17 is delivered to the other terminal 45 of the comparator. On the voltage on the pin 43 increasing above the reference voltage, the output pin 46 of the comparator goes from a logic low to a logic high, thereby indicating a voltage drop across the vehicle battery. This puts a high on pin (19) of the microcontroller (16) which activates an alarm means. Also disclosed are means for arming and disarming the apparatus, eg by radio, and other means, eg ultrasonic transmitter and receiver, for detecting intrusion into the vehicle. <IMAGE>

Title: Turbine or impeller rotor
Inventor: GOODDEN JOHN JASON PAUL
IPC: F03D9/00
Filed: 1991-02-25
Abstract: A turbine or impeller rotor of the type comprising a plurality of vanes 1, 2, or (32, 33, fig 4) mounted in at least one circumferential array around a common axis of rotation 8, (27) of the rotor, each vane being rotatable about an individual axis 3 spaced from the common axis of rotation under the control of a linkage mechanism 11, 12, 13, 14; (40-45, fig 5) which constrains each of the vanes to turn through an angle about its individual axis (3) which is one half of the angle turned by the vane about the common axis of rotation and in the opposite sense. Each vane is formed of a flexible laminar material allowing it to adopt a curved configuration to enhance the contribution to the thrust of the impeller or the torque of the turbine made by a vane due to the fluid-dynamic force generated by a pressure differential created by the fluid medium flowing over the curved surfaces of the vane when in an orientation inclined to the direction of flow of the fluid. A plurality of vanes carried on respective arms of the rotor may also be provided. A turbine of this type may be used to drive either an impeller of this type or a screw propeller to provide propulsion for a boat. <IMAGE>
