Title: Vibratory gyroscopic rate sensor
Inventor: FELL CHRISTOPHER
IPC: G01C19/5677
Filed: 1996-10-08
Abstract: A rate sensor for sending applied rate on at least two and preferably three axes includes a vibrating structure (6). Means are provided for vibrating the structure (6) in a Cos 2# carrier mode at a Cost 2# frequency. This carrier mode provides the linear momentum components necessary to couple energy into response modes in every geometric plane. Rotation about one or other of the axes in the plane of the vibrating structure will generate Coriolis forces which cause a rocking motion of the vibrating structure (6) about the same axis at the carrier mode frequency. The vibrating structure (6) has a substantially planar substantially ring or hoop like form shaped and dimensioned to match the frequencies of the Cos 2# mode and rocking mode vibrations in the structure (6) resulting in a resonant amplification of the rocking mode vibrations caused by rotations around axes in the plane of the structure (6). Rotation about the third axis normal to the plane of the structure (6) generates Coriolis forces which couple energy into the degenerate Cos 2# response mode. The Cos 2# response and rocking mode vibration amplitudes are proportional to the applied rate and means are provided for detecting the Cos 2# response mode and rocking mode vibration and thereby the applied rate.

Patent GB-2314219-A (GB)
Title: Protecting high voltage power distribution transformers from lightning strikes
Inventor: DOONE RODNEY MEREDITH
IPC: H02B5/01
Filed: 1997-06-03
Abstract: Even when the terminations of the high voltage winding or windings 2 of a power distribution transformer 1 are protected by surge arresters or diverters 7, 8 connected to ground via the transformer casing 5 and casing earth connection, a lightning strike may cause transformer failure due to the surge current (typically 10KA) passing through the surge diverter 7 or 8 and the casing ground resistance Rc-e (typically 10 ohms) giving rise to a transient voltage (typically 100KV) on the casing 5. This transient voltage appears between the casing 5 and the grounded neutral termination of the low voltage winding 3 of the transformer and exceeds the withstand voltage of the low voltage winding. To overcome this problem, a high voltage surge arrester 10 is connected between the casing 5 and the neutral termination of the low voltage winding 3. The surge arrester 10 is chosen to clamp the transformer casing 5 to a voltage (eg. no greater than 20KV) which is below the withstand voltage (eg. 25KV) of the low voltage winding 3. When used in a distribution system having auto-reclosing type circuit breakers on the high voltage side, the arrester 10 must also be able to withstand, for the re-make period of the circuit breaker, a fault voltage to which it will be subjected when a ground fault exists on the high voltage side. In an 11KV distribution system, arrester 10 must withstand 7KV for 10 seconds under such ground fault conditions. The transformer 1 may be pole-mounted, and additional protection may be provided by connecting the low voltage lines to ground by means of low voltage surge arresters located at the next pole downstream of the low voltage side of the transformer.

Title: Overfill Protection Device For A Fuel Storage Tank
Inventor: STUART GRAHAM MANSFIELD
IPC: F16K31/34
Filed: 1998-05-12
Abstract: An overfill protection device for a fuel storage tank 3 comprises a fill tube 5 fitted with a fill valve 4 which is connected to a piston or diaphragm 6 moveable in a chamber 7. A vent valve is connected via an aperture and conduit 9 to the chamber 7 and is opened as the liquid level in the tank rises, causing a pressure difference across the piston or diaphragm and subsequent movement which closes the fill valve 4. Liquid initially enters the device through tube 16, exits through tube 5 and fills the chamber 7 on both sides of the piston and along the conduit 9, as the piston is not sealingly engaged in the chamber 7. When a sensing means, such as a float 50, reaches a certain level, the vent valve opens by, for example, the lining up of apertures 56 on an inside sleeve with apertures 53 (not shown) on an outside sleeve. Liquid from above the piston is discharged into the tank and the piston 6 moves upwards in the chamber 7 causing the fill valve 4 to close. The sensing means may be electronic, and the vent valve may be electronically operated. The fill valve 4 may be a butterfly valve or a poppet valve. A diffuser in the form of two or more parallel plates (107, fig. 8) may be fitted to the bottom of the fill tube to induce laminar flow.

Abstract: A primary power source 12 and a reserve battery source 14 are provided for an electrically controlled lock actuator system which has a lock actuator 16 energised via a transistor 42 controlled by a processor 28. The system may be part of a vending machine. Primary source 12 is connected to actuator 16 via a diode 24, and battery 14 is connected to actuator 16 via a diode 20, a normally-open switch 18 and a diode 26. Primary source 12 is also connected to the input 52 of a voltage regulator 50 and via a diode 22 to a point intermediate diode 20 and switch 18. Primary source 12 is normally at a sufficiently higher voltage than battery 14 such that if switch 18 is closed, then diode 20 is off, actuator 16 is powered from source 12, a supply input Vcc of processor 28 receives power from source 12 via regulator 50, and a voltage is applied to an input 30 of processor 28 from source 12 via diode 22 and switch 18. If primary source 12 fails, power is supplied from battery 14 via diode 20, switch 18 and diode 26 both to actuator 16 and (via regulator 50) to processor 28, and input 30 receives voltage from battery 14 via diode 20 and switch 18. The arrangement of switch 18 and the diodes ensures that the battery 14 is only used when necessary, thus extending its life. Input 30 may be a triggering input to which voltage is applied only when switch 18 is closed, processor 28 being responsive to this input to operate actuator 16 when lock control information is received at an input 36, such as from a card reader for a card which closes switch 18 when inserted into a card opening of the reader.
