Title: Ultrasonic range finding
Inventor: BARRETT LESLIE MELBOURNE
IPC: G01S15/36
Filed: 1986-03-25
Abstract: Range measurements are made by transmitting an ultrasonic signal of periodic waveform by means of transmitter (10) towards a target (16), receiving the echo at receiver (14), measuring the phase difference between the transmitted and received signals using a phasemeter (18), adjusting the transmitted signal frequency of a manually adjustable variable frequency oscillator (12) and measuring the resulting phase difference between the transmitted and received signals, and computing from the known transmitted signal frequencies and phase differences, a value for the range of the target (16). In an alternative arrangement, the pair of transmitted signal frequencies used may be such that they render the transmitted and received signals in phase but in such a way that the number of wavelengths spanning the path of travel differ by an integral number, eg 1, of wavelengths. <IMAGE>

Title: Telephone system and terminal
Inventor: HILL RICHARD
IPC: H04M1/738
Filed: 1987-05-14
Abstract: Some recent telephone systems, especially PBX's, use four-wire lines between the exchange and the terminals with specialised signalling. Conventionally this uses four-wire to two-wire converters at the subscriber's end, to which an ordinary telephone set is connected. In the present case no such converter is used at the terminal, with the receive pair (RX PAIR) directly connected to the earpiece (2) and signal detection means. in addition the telephone transmitter (10) is connected to the transmit pair (TX PAIR). All the circuitry, except for an external power supply, is in the same case as the telephone. A tone caller 7 is operated by control processor 6 on detection of a received 2280 Hz signal at 3, of a level above noise detected at 4. Dialed digits are sent as 2280 Hz bursts at 10 pulses per minute. <IMAGE>

Filed: 1989-08-01
Abstract: An electric liquid heating container includes electrical connectors engageable with electrical connectors on a separate base unit 12 to enable electrical power to be supplied to a heater 2 of the container. The container or base unit comprises a thermally-sensitive control 6 including a thermally sensitive actuating means 21 exposed to steam or vapour issuing from a passage 22 and resulting from liquid within the container boiling, and an overcentre spring mechanism 123 including an overcentre lever 24 which is in response to operation of the actuating means 21 from a first stable position in which a set of switch contacts 30 is closed and power can be supplied to the heater and a second stable position in which the contacts 30 are open and the heater is disabled. The base unit 12 incorporates a member which is arranged to cooperate with a part 46 of the overcentre spring mechanism such that, if the container is moved towards the base unit 12 with the overcentre lever 24 in the first position, the lever 24 is moved to the second position in which the heater is isolated before electrical connection is made between the complementary connectors of the container and base unit. The lever 24 can thereafter be moved back to the first position to energise the heater by a manually operable reset mechanism 40 when the container is fully engaged with the base unit. The heater 2 is disabled by a second thermal actuator in the event of the heater 2 overheating. <IMAGE>
Patent GB-2222397-A (GB)
Title: Loading bulk material into containers
Inventor: FORSTER JOHN FREDERICK GEORGE
IPC: B65G43/08
Filed: 1989-08-30
Abstract: To load bulk material into a shipping container 12, an elongate conveyor 26 is used which extends right inside the container. As the container fills up and blocks the discharge openings of the conveyor, the energy needed to drive the conveyor increases. This energy is monitored and when it rises in this way, a signal is produced, and relative movement takes place between the conveyor and the container so that the discharge openings come to lie in a part of the container which has not yet been filled. This process is repeated until the container is completely filled. Two screw conveyors are employed, each within a hollow boom. <IMAGE>

Title: Temperature compensation control circuit for exponential gain function of an AGO amplifier
Inventor: YAMASAKI RICHARD G
IPC: H03F1/30
Filed: 1991-09-16
Abstract: A temperature compensation control circuit to maintain a constant control gain in an AGO (automatic gain control) amplifier. The circuit compensates for the inherent temperature dependence, without using any special processing or non-standard device structures, by using the voltage drop across n diodes in series to produce the control voltage difference Vc-Vc*. These n series diodes are coupled to the collectors of a PNP emitter coupled pair Q19, Q20 having emitter resistance. This causes the control voltage difference to be dependent on temperature (nkT/q), but this dependency cancels out with the other inherent temperature dependency in the exponential function of the AGO amplifier which is also produced by a diode form. Thus, the circuit provides temperature compensation with minimum component matching problems and without the need for a PTAT (proportional to absolute temperature) current source. The circuit supplies the control voltage Vc-Vc* to emitter coupled transistors (Q7, Q8. Fig 1) of emitter coupled gain stages (Q1, Q2, Q5, Q6). <IMAGE>

Title: Self closing safety valve for oil/gas drilling pipe-lines.
Inventor: KERNAGHAN JOHN VICTOR
IPC: E21B34/10
Filed: 1991-11-04
Abstract: The valve is an integral part of a pipe section A which forms the pipe-line from the below-surface gas/oil source, to the drilling rig/well-head. The pipe wall is hollow to allow the flow of hydraulic fluid which maintains the position of a retaining sleeve C which in turn holds open the valve fins E and allows free flow of material through the pipe-line. Hydraulic pressure is maintained within the wall of the pipe by a jockey pump and a connecting hose and a non- return valve, all of which are positioned at the well-head. In the event of fire/explosion at the well head, the system fails safe, and the valve E is forced closed resulting in no flow within the pipe Line. The system can be designed to allow several valves to be installed 'in line'. <IMAGE>
