Abstract: The invention relates to the field of color electrophotography. 
<??>In order to form electrostatically an image of an original having black and color portions a method and apparatus involve applying to a first photoconductive surface (12) an electrostatic charge corresponding to black areas and developing them with toner. Then, to form an electrostatic charge corresponding to color areas on the first surface for separate development, the first surface (12) is charged in areas corresponding to black and color areas, and a second photoconductive surface (13) is charged in areas corresponding only to black areas. The two surfaces (12, 13) are brought adjacent one another, and the part of the charge on the first surface (12) corresponding to black areas is eliminated either due to the second surface (13) charge being of opposite polarity, or by the second surface (13) charge being on a screen which is used to control charged particle flow onto the first surface (13).

Abstract: Such a wall lining is used to face walls and as a protection against dampness and cold or heat. To permit simple erection of the wall lining, the slab (1) used for aesthetic purposes is connected, on its rear side, to an insulating slab (2), resulting in an integrated component. The edges of this component are of rabbet-like design, so that the components can be fitted together to erect a wall lining. At the same time, the rabbet seals the cross joints between the components and helps to align the wall lining evenly and uniformly over the length of the joint. The components can be directly bonded to the wall (9) to be faced or they possess socket connection elements (11) which can be pushed onto an angle section rail (10) screwed to the wall. <IMAGE>

Abstract: The housing of the loudspeaker enclosure comprises a front baffle, two side walls (14), a rear wall (16), a cover plate (15) and a bottom plate (17). In the baffle, two low-range loudspeakers (2, 3) and two mid-range loudspeakers (4, 5) are mounted and in a further baffle set back with respect to the said baffle, two high-range loudspeakers (7, 8) are mounted. To suppress standing waves and vibrating air columns, the chamber bounded by the said walls and plates is subdivided into three sections of space (21, 21', 21'') in the interior of the housing by two partitions (18, 19) arranged to be inclined with respect to the side walls. Each partition contains a cutout (23, 24) in which a sound attenuating element (25) is arranged. In parallel with the rear wall (16), a separating wall (30) for forming a pressure equalising passage extending therebetween is arranged. The input to the pressure equalising passage is a slot (31) between the separating wall and the bottom plate and the output is a slot (32) between the cover plate and the rear wall. The pressure equalising passage is partially lined with sound absorbing material and is used for equalising extremely high sound pressures inside the housing with respect to the ambient atmosphere. <IMAGE>

Abstract: Apparatus for measuring the impedance or another parameter of a device by reference to the standing wave pattern set up in a transmission line along which microwave energy is applied to the device. A section of the transmission line has three spaced probes from the output voltages of which corresponding digital values are produced and digital computing means calculates the impedance from the values. Calibrating measurements using a matched load and a short circuit instead of the device are performed earlier and the result representing probe sensitivities and energy wavelength used to simplify and speed up the calculations, so that a reasonably smooth display plot of the impedance with varying energy frequency can be produced in real time. The computing means has an 8-bit microprocessor for the handling and a 16-bit microprocessor to perform the calculations.

Abstract: The present invention relates to a mixer for use at high microwave frequencies (typically 21.8 x 23.2 GHz) in a low cost communications application. The invention utilizes low cost microwave components, including a low cost compartmented waveguide (27), shared by the signal and local oscillator and extensive microstrip circuitry (26). The provision of a pair of novel ¼ wave impedance transformers (31,32,33,34) coupled into the waveguide compartments provides efficient antenna and local oscillator input filtering, and efficient coupling from the waveguide sections to the microstrip circuitry. The mixer operation is carried out in the microstrip circuitry, which contains a hybrid coupler, a balanced diode detector, and the required mixer output filter. The arrangement is of low cost, and provides a low noise figure (7 db including the preamplifier), good band selectivity (15 db return loss over the communications band), and low local oscillator radiation.

Abstract: In a vortex flow meter for measuring a varying flow rate of a fluid through a conduit, an oscillation compensating apparatus (10) is constructed to remove undesirable externally derived oscillation noise which is applied to the flow meter. An elongate vortex shedding member (12) extends into the conduit (14) through part of its wall. The shedding member (12) forms a shedding portion inside the conduit (14) and a compensating portion outside the conduit. The shedding portion carries a first oscillation sensor (22) therewith and the compensating portion, a second oscillation sensor (24). The first sensor (22) is sensitive to an oscillation component caused in the shedding portion by a vortex train shed in the conduit, and an externally derived oscillation noise component. The second sensor (24) is sensitive to the noise component only. All these sensed components are combined to cancel the oscillation noise so that only the oscillation component in the shedding portion is picked up.
