Abstract: In a method of starting an asynchronous motor, the voltage supplied is rapidly increased until a change in the derivative of the phase shift between the voltage applied and the current supplied is detected, whereupon the voltage supplied is increased more slowly until it has attained its full value. An apparatus for carrying the method into effect comprises a current detector (5) for generating a signal representing the phase of the motor current, a voltage detector (6) for generating a signal representing the phase of the motor voltage, and a phase detector (7) for generating a signal representing the phase difference between the motor voltage and the motor current. Furthermore, means (8) are provided for detecting a change, exceeding a predetermined value, in the said phase difference, as well as means (8) for rapidly increasing, upon start of the motor, the proportion of the half periods of the AC voltage applied to the motor, during which proportion the motor is supplied with current, until the said change in the phase difference is detected, and for then increasing the said proportion more slowly until the voltage supplied has attained its full value.

Abstract: Foundry molding material is poured or pneumatically infed into a mold frame arrangement containing at least one pattern, a molding frame and a filling frame. Subsequently, the foundry molding material is compacted by a compacting arrangement containing, for example, any one of a compressed-air surge compacting device, a combustion-force surge compacting device, a pressure compacting device, a vibrational compacting device or a combined pressure-and-vibrational compacting device. Also during such compacting operation at least the predominant portion of the foundry molding material contained in the filling frame is displaced into the molding frame. During such compacting operation a preselected expanding gas is infed into predetermined local regions of the foundry molding material while such material is being compacted. As a result, there are formed zones of reduced packing density in the foundry molding material. During the further compacting operation, but in any case at the end of such compacting operation, the zones of reduced packing density are eliminated and the packing density of such zones is at least approximately equalized with the packing density prevailing in the remaining zones of the foundry molding material.

Abstract: A method for infinite speed variation of A.C. motor by means of slip-converter with combination of at least two asynchronous motors, a slip motor, a converter motor comprising two rotors, etc., and an infinitely variable speed A.C. motor according to this method are disclosed. The combination is called the motor Type I in which the rotary magnetic field is used to perform frequency-converting and speed variation of the motor, or an A.C. potential having required frequency induced by the other rotor of the converter motor is used for turning an auxiliary motor. The combination is called the motor Type II in which an A.C. potential having required frequency induced by the other rotor of the converter motor is used for feedback to an electric network. 
<??>The motor type I without an electric brush an a commutator, cabable of reversing rotation, has a wide variable speed range from zero. It is easy to start with no overcurrent and can be started frequently. It has high reliability and overload capacity. The performance of the motor is better at lower speed. In high power operation these said advantages are still better. 
<??>The motor Type II is suitable for use in the fields where the motors with infinite speed variation are used. It can also be used for explosion-proof equipment with infinite speed variation. 
<??>The motor Type II with constant outpunt torque is small simple and sturdy in construction, capable of reversing rotation. It is inexpensive and suitable for speed variation of blower, fan and pump.

Abstract: A fluid valve includes a sleeve (12) having inlet and outlet ports (26, 18). There is a stem (16) movable within the sleeve between open and closed positions and having an inlet port (40) and an outlet port (49). The stem inlet port is in communication with the sleeve inlet port and the stem outlet port is movable into registration or communication with the sleeve outlet port to define a path of flow through the valve. A seal (34) is carried by the sleeve and cooperates with the movable stem to close the path of flow. There are means for reducing noise normally attendant to opening the valve which includes a passage (48) in the sleeve directly adjacent the sleeve outlet port. The passage is in communication with the stem outlet port as the stem outlet port initially moves to open the path of flow to divert water and reduce pressure at the communicating outlet ports.

Abstract: In a television system a digital picture signal is subjected to a transform coding for the purpose of bit rate reduction. In order to detect motion effects between the two fields of a picture, these fields are also examined in a motion detector 8310. If no motion is detected, intraframe transform is employed and if motion is detected intrafield transform is employed. Small motion effects can be eliminated by subjecting the picture signal to a median filtering before subjecting it to an intraframe transform.

Abstract: A method of establishing a digital time-division duplex radio communication link between one of a plurality of portable units and a base unit in a cordless telephone system. Transmissions from the base unit are allowed only on a ping-pong basis with transmission bursts from all the active transmitters in the base unit being synchronised with one another. This prevents blocking of receiver sections due to co-sited transmitters transmitting at the same time on a different channel. The difficulty of synchronising the transmission bursts of the active portable units with their respective transceivers within the base unit is overcome by allowing the portable unit to make an initial continuous call comprising multiple identical sequences of data containing units small enough to be completely received within the limited reception windows of the base unit. After the initial call has started communication, an exchange of signals takes place on a ping-pong basis to establish synchronism between the portable unit and base unit. Finally, if all is well, the system reverts to speech mode.
