Abstract: In a hot standby transmitter system, each identical transmitters, one of which is a primary and another one is a standby, comprises an image-cancel type mixer (41, 51), which outputs upper or lower sideband waves of a local frequency, according to its internal connection controlled by a switch controller (3). The switch controller (3) controls the internal switches (416, 516) and an RF switch (6), so that the primary transmitter outputs a predetermined primary one of the sidebands and the standby transmitter outputs another sideband, and the RF switch (6) selectively connects the output of the primary transmitter to outside. The standby transmitter undesirably outputs a small level of the primary sideband though it should be theorectically zero. This low level primary wave component in the standby transmitter's output allows a reduction in the isolation amount of the RF switch (6), compared with high isolation amount required in a prior art method where the standby transmitter outputs the primary wave in as high as the primary transmitter level, in order to keep the ratio of power level from the primary transmitter to the power level from the standby transmitter higher than a predetermined requirement level. The circuit to detect a fall in the output power is simple compared with a complex circuit required in another prior art method where the standby transmitter outputs the less primary wave than the primary transmitter.

Abstract: A dispensing toothbrush has a hollow handle, which has a supply chamber for tooth-cleaning media, a stem at one end of the handle, bristles at the free end of the stem, an outlet opening in the vicinity of the bristles, which is connected to the supply chamber via a channel arranged in the stem, a pumping device between the supply chamber and the channel, an actuating member, arranged at the other end of the handle, for the pumping device, and a valve between the supply chamber and the channel, which valve closes when the pumping device is actuated and allows tooth-cleaning medium to be conveyed into the channel to the outlet opening and which opens into the state of rest when the pumping device is returned, in which case tooth-cleaning medium can continue to flow out of the supply chamber through the valve. The supply chamber has a cross-section which increases in two steps towards the pumping device and thus forms cylindrical sections. In each cylindrical section there is a piston. The piston in the cylindrical section with the smallest cross-section closes said cylindrical section. The piston in the adjacent cylindrical section with the larger cross-section is of annular construction and forms, with its inner edge, a tight receptacle for the adjacent piston in the adjoining cylindrical section of smaller diameter. This receptacle has a stop, against which the piston of smaller diameter strikes when it moves into the receptacle.

Abstract: The burner comprises a tubular body composed of an inner bush (12) and an outer bush (10). The inner bush (12) carries a spray nozzle (11), an ignition electrode (23) and an observation tube (40). An annular space (E) arranged between the two bushes provides the inlet for a flow of oxidiser. A primary flow (A) of supply of oxidiser gas is led in through apertures (15) towards a deflector plate (18). This arrangement permits an area of toric-cyclonic combustion (33) to be obtained by virtue especially of the existence of slots (16) let into the deflector plate (18) and inclined blades (13) mounted in the space (E) located between the inner bush (12) and the outer bush (10). The advantages are a better homogeneity of the mixture, an increase in the dwell time of the mixture in the combustion area and better recycling of the combustion gases. <IMAGE>
