Abstract: A conference circuit in a digital telephone switching system includes a first code converter (CCL), which converts nonlinearly coded speech samples into linearly coded speech samples, and adder (ADD), which sums the converted speech samples originating from the participants in the conference, and a second code converter (LCC), which reconverts the sum values into nonlinearly coded speech samples. To avoid distortion without increasing the insertion loss, the speech samples of the individual participants are integrated with respect to time and compared in an evaluation circuit (EVC). The speech samples of the loudest participant are fed to the adder unattenuated, while those of all other participants are attenuated by a predetermined value before being added.

Abstract: In order to enable a piston cylinder unit 1,2 with air entry through a hollow shaft 6, to be operated in either mode of operation with a single type of shaft, it is proposed in accordance with the invention to manufacture the shaft 6 in three parts, namely an upper air inlet portion 6a, an intermediate portion 6b which provides access for air to the cylinder via one or more apertures 18, and an operating end portion 6c. These three parts are threaded together and sealed by seals 21 and 24. Captive nuts 3 and 8 are provided at both ends of the cylinder so that the cylinder may be attached to a yoke 4 by either end, with the opposite end carrying a bearing 9 for the air inlet portion 6a of the shaft. If it is desired for the piston to operate in the opposite mode of operation, the portions 6a and 6c are interchanged and the cylinder is attached to the yoke using the captive nuts 8 rather than the nuts 3.

Abstract: The invention relates to a locking arrangement which can be released from its locking state by means of a pressurized fluid, and to a nozzle through which pressurized fluid can be supplied to the locking arrangement to release the same. The locking arrangement includes a latch bolt (6) which is connected to a plunger (5) arranged for axial movement in a chamber (4), the plunger dividing the chamber into two, substantially pressure-tight part chambers (4a, 4b). The plunger (5) is biassed towards its locking position by a spring means (8) and can be moved axially to a lock release position, against the force of the spring means by a pressurized fluid, e.g. compressed air, lead into the one part chamber (4a). To this end, the aforesaid one part chamber (4a) communicates via an opening (12) in a chamber wall (13) with a fore-chamber (14) which is located externally of the chamber (4) and which communicates with the other part chamber (4b) through a second opening (15) in the aforesaid chamber wall (13). The opposite external wall (17) of the fore-chamber (14) is provided with a third through-passing opening (16) which is located opposite the aforesaid second opening (15). The nozzle (18) according to the invention is formed so as to enable it to be inserted into the aforementioned second and third openings (15, 16), so as to seal the same with its outer surfaces. The nozzle (18) has a first, internal channel (27, 23, 24) through which pressure fluid can be passed into the fore-chamber (14) from a pressure-fluid line connected to the nozzle, and a second, internal channel (20, 21) through which the other part chamber (4b) is placed in communication with the surroundings.

It has columns, interconnecting pieces attached to them and clamps joining the columns and interconnecting pieces. Essentially, the columns consist of parallel column members attached to each other. At least at two places-favorably at the ends of the column members-they are attached to each other by means of a coupling member overlapping two column members and/or intermediate interconnecting piece joining two columns via two releasable clamps. Each column member is clamped to the coupling member and/or the interconnecting piece. The carcase has interconnecting pieces which join the column members. They have sections dimensioned to the drift holes made by the notches on the facing surfaces of two column members. Adjacent these drift holes the interconnecting pieces have shoulders, edges or similar configurations which are supported by the column surfaces and which prevent displacement relative to the columns. The essence of the invention is that minimum expenditure of labor, material and energy provides furniture of high aesthetic level and use value. They are available to the customers in unit packets. The customer can assemble it himself without using any special tools or professional skill. The requirements for storage and transport is minimum. Due to the releasable attachments, the piece of furniture can be disassembled and no glue application to tapestry or mechanical clamping is required so that it can be easily removed and replaced in case of cleaning or substitution.

Abstract: In a deflection circuit, a flyback transformer and a retrace resonant circuit that includes a deflection winding are mutually coupled by a relatively small capacitor during the retrace interval so as to reduce transient distortions that may be caused by a sudden high beam current change. East-west modulation is provided to the deflection circuit output stage via an impedance having a relatively large value at the retrace frequency. A resonant circuit that includes the deflection winding and the flyback transformer is tuned to the retrace frequency. Synchronization information of the current through the deflection winding may be derived from a winding of the flyback transformer.

The individual base and emitter areas (3, 4 and 5, 6) are distributed evenly over the surface of the semiconductor substrate (1). The areas of the same type (3, 4 and 5, 6) in each transistor stage are connected to each other in parallel by the current supply contacts (8, 9, 10) in the direction from the periphery to the centre of the semiconductor substrate (1). The individual base areas (3, 4) are insulated from each other by the common collector area which emerges on the surface of the semiconductor substrate (1). In the centre of the semiconductor substrate (1) is an assembly contact (13) leading to the individual emitter areas (6). The assembly contacts (14, 15, 16, 17) connected to the individual base areas (3) are distributed evenly over the peripheral surface of the semiconductor substrate (1).
