Abstract: The folding curtain, especially for conservatories, has a plurality of tensioning wires which pass through the curtain in receptacles provided spaced apart, the ends of which wires are attached in the tensioning shaft or in a lower rail of the curtain, and which can be tensioned via a device fastened to the head rail in order to prevent sagging of the curtain. Serving as tensioning device is a shaft, whose ends are received by bearing boreholes which are seated in the limbs of the U-shaped head rail, the tensioning shaft, on whose outer surface the tensioning wire can be wound, is rotatable by means of a tool in such a way that the tensioning wire is tightened. The rotary movement of the tensioning shaft can be arrested by a nut. Serving as tool are a spanner or form-fitting elements which come into effective connection with the tensioning shaft. <IMAGE>

Abstract: An indexing mechanism in a machine tool for selectively positioning plural pin portions of a crankshaft at the machining position aligned with the work spindle, wherein a indexing member engaging with the crankshaft through an engaging pin is rotated by an indexing motor through a gear train. The crankshaft is initially rotated in a first direction until a selected pin portion engages with a rest shoe of a rest device provided on the bed in order to be positioned in a reference angle position, in which the selected pin portion is located at the machining position aligned with a work spindle. The crankshaft is then clamped on the chucking device. After that, the indexing motor is rotated in a second direction opposite to the first direction until the load of the motor exceeds a reference level, so that the influence of a backlash in the gear train and a clearance between the engaging pin and the crankshaft is eliminated. After the completion of a grinding operation on the selected pin portion, the indexing member is thereafter rotated in the second direction by a predetermined amount so as to position a next pin portion in the machining position.

Abstract: To remove pores and lattice defects in gold film plated on a substrate, the gold plating film is irradiated with a first laser beam to bring at least the surface of the film into almost melted condition, and then coolded in air. Further, it is preferable to anneal the melted gold surface by a second laser beam weaker than the first laser beam before air cooling, thus reducing the thickness of the gold film and therefore the material cost of electric contacts, for instance.

Abstract: A method of testing the effect of an agonist or an antagonist to B lymphocyte cell surface protein CD20 in B lymphocyte function which involves determining calcium ion flux across the B lymphocyte membrane, contacting the B lymphocyte with the agonist or antagonist, and determining the change in calcium ion flux across the membrane after exposure of the B lymphocyte to the agonist or antagonist, is described. In preferred embodiments of the method the agonist or antagonist is a ligand that binds CD20 or an antibody to CD20.

Abstract: A subharmonic mixer comprises two pairs (60, 62) of matched antiparallel GaAs diodes disposed on a dielectric slab (8) and operative with microstrip circuitry. By suppressing the fundamental mixing products, mixing the radio frequency signal with the second harmonic of a local oscillator (LO) signal and using relative phase differences of the LO signals in the two pairs (60, 62) of diodes. undesirable effects from spurious signals are minimized. The radio frequency energy is coupled through a waveguide (90) to the diode pairs (60, 62), and the intermediate frequency from the radio frequency and the second harmonic of the local oscillator frequency is coupled to a quadrature hybrid {70) which supplies the desired intermediate frequency at an output port (76) and suppresses undesired frequencies at a terminated port (80). Bandpass filters (30, 32). low pass filters (40, 42). and local oscillator frequency chokes (50, 52) limit propagation in the microstrip circuitry. A phase shifter (20) in one path (16) for the local oscillator frequency inserts a 90° phase delay for the second harmonic, relative to the other path (14).

Abstract: A digital mixer circuit is disclosed in which a plurality of digital signals (x1,x2) are shifted in bit and applied to a plurality of selectors (11-18), which are operated in accordance with a predetermined weighting coefficient (K 0∼7 ), thereby producing a plurality of selected data trains shorter in bit length than the input signals. The plurality of selected data trains are added (19-25) to each other to calculate the sum. Since the input signals are added with the bit length thereof shortened, the rate of increase in the number of adder gates is smaller with the increase in the number of steps in which the mixing ratio is changeable, thereby facilitating the circuit integration.

Abstract: The starting point are known space/time switching networks. The technical problem is that the capacity of a switching network could be increased by increasing the clock frequency. However, changing all interfaces, which is necessary for this, is only possible over a very long term. A transition solution is required which allows the gradual exchange or further extension using new interfaces.   The basic concept is the use of switching elements, the inputs and outputs of which can be switched individually between two transmission rates. Example: a frame structure which is based on the lowest transmission rate is used as a basis. Within such a frame, signals with the highest transmission rate can also be temporarily stored and time-converted. Provision is made for 4 Mbit/s and 32 Mbit/s. The advantage is that it is easily possible to combine several channels into higher-capacity connections (N x 64 Kbit/s).   The higher transmission rate is only used when actually required. This reduces the power dissipation and the interference radiation. <IMAGE>

A generator of this type is to be improved with respect to being able to influence the oxygen flow and the duration of delivery by means of a reaction control element by virtue of its material and/or its shape. The improvement is achieved by one or more reaction control elements (71) made of sheet metal being arranged parallel to the direction of progress of the reaction front. Alternatively, the object can also be achieved by the reaction control element being fashioned in the form of a conveyor screw which is made of sheet metal or a thermal insulation material. The object can furthermore also be achieved by the reaction control element being constructed as a spirally coiled strip made of sheet metal or a thermal insulation material in a can-shaped housing. <IMAGE>
