摘要： A circuit for measuring inductance and resistance of a load (L) having an integrator (I) and a comparator circuit (C1) which cause a triangular current waveform in the load (L). An amplifier (A) converts the load voltage (V L ) to a voltage which is referenced to common. Different components of this voltage are then averaged over appropriate times to provide levels representative of the inductance and resistance of the load (L).

摘要： The invention relates to an adjustable pipe bend which has at least two parts (10,10a) joined by flanges (12,12a) which incorporate an electrical fusion element in the form of a plastic annular disc (15) with a heater wire (16) located at or adjacent both surfaces of the disc (15).
A number of embodiments of the invention illustrate different adjustable bends, the arrangement being that the bend is adjusted to a required position and then the heater wire (16) has a voltage applied to it to produce a heating current which causes the plastic annular disc (15) and adjacent plastic faces of the flanges (12,12a) to melt sufficiently to cause fusion between the two parts (10,10a) of the pipe.

摘要： PCT No. PCT/AU94/00784 Sec. 371 Date Aug. 14, 1996 Sec. 102(e) Date Aug. 14, 1996 PCT Filed Dec. 21, 1994 PCT Pub. No. WO95/17642 PCT Pub. Date Jun. 29, 1995The invention provides, in a first form, an expandable plug for regulating pressure or flow within a tube. The plug has an inflatable bladder (12) for diametral expansion by internal fluid pressure introduced by inlet (14). The plug is reinforced by an envelope (26) of cords (28) which spread laterally upon inflation of the bladder to provide diametral support to the bladder. In a second form of the invention, an inflatable plug positioned in a tube of internal diameter d is controlled according to the equation Pp= DELTA P+Pd wherein Pd is the internal pressure in the plug, DELTA P is the differential pressure across the plug and Pd is the plug free expansion pressure for diameter d.

摘要： A fusion control unit having a casing (10) with a panel (11) through which information can be communicated optically. Infra-red transmitter (24) transmits information from a microprocessor (29) within the fusion control unit to an external optical communication box (30) and infra-red receiver (25) receives information from the external optical communication box to transmit to the microprocessor (29). The fusion control unit can thus communicate with an external computer, for example, without compromising the integrity of the unit.

摘要： This invention relates to a system of identifying and providing information concerning hidden pipelines, cables, ducts, passages etc.
In Figure 1 a pipeline 10 is located below ground level 11 and has on it an information containing element which is interrogatable, and is clipped into a recess 13.
An alternative is to have the element in the form of an inertly packaged coded tag 12A attached to the pipe by straps.
A transmitter/receiver 14 is connected by a flexible cable 15 to an antenna 16. The transmitter/receiver has a power supply 17 and display 18. Connected to the transmitter receiver 14 is a decoder 19 and a recorder 20. On interrogation, the interrogatable element 12 responds and returns a signal which is picked up by the antenna 16 and supplied to the transmitter receiver 14 where it is decoded and recorded and also displayed on the display 18. Information displayed may provide details as to depth and direction of alignment of the pipe 10, the material of which it is made, the fluid which is flowing through it, etc.
