Abstract: The invention is directed at a work surface mechanism for connecting a primary work surface to a secondary work surface, the work surface mechanism comprising: a track system, located underneath the primary work surface; a main body including primary work surface mounting apparatus for mounting to the track system; a pivot bar, connected to the main body; and a pair of arms, each of the pair of arms connected at one end to the pivot bar and to the secondary work surface at the other end; wherein the secondary work surface can be stored directly stored underneath the primary work surface when not in use.

Abstract: The invention is directed at workstation having a workstation that is able to be tilted The tilting assembly for the workstation includes a actuator, a cable and a gas cylinder.

Abstract: A radio telemetry system for collecting the readings of consumer's electricity consumption meters includes a master station (1) carried by a vehicle (1) and a plurality of transponders (3), each of which holds an electrical quantity indicative of an amount of electrical power consumed as measured by the meter associated with that transponder (3). The transponders (3) and the master station (1) communicate such that the transponders (3) transmit to the master station (1) signals containing information as to the values of the aforesaid electrical quantities held by them. Such communication takes place on a relatively quiet channel, of a number of channels, as determined by the master station (1) such that the system is capable of operating satisfactorily when the master station (1) and the transponders (3) utilise relatively low power transmitters (7, 19).

Abstract: An electrical power measuring device wherein signals (V.sub.i, V.sub.v) representing one of the current and voltage supplied to a load are applied to the input of a sigma delta modulator (9), and the state (0 or 1) of the modulator output together with the polarity of the other one of the voltage and current values, is used to determine the sense in which the digital signals representative of successive samples of the other one of voltage and current values are accumulated in an accumulator (11). The count in the accumulator (11) consequently increases at a rate representative of the power supplied to the load.

Abstract: An electricity metering equipment wherein, in order to reduce the possibility of fraudulent consumption of electricity, there is provided in addition to the usual meter (3) for measuring the amount of electricity consumed in a load, an independent device (5) which produces a signal representative of the current supplied to the load. A comparison device (4) then compares the signal with the rate of electricity consumption measured by the meter, and an output signal is produced if there is a discrepancy which may be used to disconnect the supply and/or transmit a signal to the supply authority.
