Abstract: VACUUM DEVICE FOR LIFTING ARTICLES  LOOSELY WRAPPED IN FLEXIBLE FILM     Abstract A vacuum device for lifting an article such as a loaf of bread which is loosely wrapped in flexible film. A vacuum chamber in the device is provided with an anterior end wall that is ported for communication of the chamber with a vacuum source and with rigid diverging sidewalls that diverge from a protruding sidewall surface at the base of the chamber to the edge of the anterior end wall.  When the article is lifted by the device, the diverging sidewalls are positioned in the path of the suspended film to cause the film to wrap around the sidewalls and the weight of the lifted article to forcibly urge the film into sealing contact with the protruding surface of the sidewalls as the film exits from the chamber.  By urging the film into sealing contact with the sidewalls, the lifted article itself advantageously assists in maintaining the vacuum seal within the chamber.  The vacuum chamber is sized and contoured for the film to be received within the chamber without being unduly stretched or permanently wrinkled.

Abstract: ABSTRACT OF THE DISCLOSURE            A phase distribution tank (1) arranged for operating with a gas-liquid mixture in a steam generator.          It is provided with port openings of at least one inlet conduit (20) and at least one outlet conduit (30) for the mixture.  The port opening of the outlet conduit (30) is intersected by the level separating the liquid and the gas phase.  The tank consists of an inlet chamber (2) and an outlet chamber (3) separated from the former by a partition (15).  Between the upper edge of the partition (15) and the wall of the tank, a respective gas passage is disposed at an elevation above the said level.  A plurality of liquid passage openings (12) is provided at the lowermost section of the partition (15).  The gas and liquid passages are so disposed that the turbulence in the inlet chamber (2) does not have a substantial effect on the level at the outlet chamber (3).  Thus, a structurally simple solution is provided for maintaining a constant liquid level within the tank.

Abstract: Abstract Testing Machines Testing machines for applying a loading to a test specimen are required in the electronics industry for tensile testing fine wire and tape peel force.  Suitable machines are known but have been cumbersome, slow to re-set and also rather expensive.  By the invention load testing machines are provided e.g. for tensile testing of fine wires or tape peel force testing comprising first and second clamp means (6, 10), one fixed the other moveable linearly, between which a specimen is clamped, and a motor (32) arranged to move the moveable clamp means (10), conveniently through a rack (46) and pinion (44) system and a clutch (42).  The machine further comprises means (18) to return the moveable clamp means (10) to an initial position in which the clamp means (6, 10) are spaced apart by a predetermined initial spacing when the clutch (42) is disengaged.  This provides rapid re-setting of the machine for a further test.

Abstract: A B S T R A C T            A drive system includes a reluctance motor, driving a load.          The motor has stator and rotor poles and magnetising windings for each stator pole.  The airgap is small so that saturation occurs during pole overlap, and the poles are constructed so that there is torque overlap between phases as successive phases are energised during rotor rotation.  A sensor provides a rotor position input to a reference waveform generator.  The output of the generator is determined by rotor position and is applied to a power converter through a current controller.          Accordingly the waveform generator establishes a relative magnitude for motor phase current for every position of the rotor during the period of energisation of a motor phase.  A further input may be applied to the system to determine the absolute magnitude of the phase current, subject to the waveform pattern established by the generator.  The rotor poles may be skewed to modify the static torque versus rotor angle characteristic of the motor, the skew being between one-quarter and one-half of rotor pole arcuate extent.
