Abstract: A machine for testing the presence and/or packing of cigarettes (11) in a group (10) comprises a housing 16 mounting a plurality of spring biased, axially displaceable tappets (13), (14) and (15) arranged in rows corresponding to the cigarette group alignment. Each row of recesses (25) for the tappet control heads (22) is provided with a pair of linear control ducts (27), (40); (28), (41); (29), (42) axially displaced relative to the tappets. If a tappet is fully displaced by engagement with an acceptable cigarette the inner duct (27), (28) or (29) will be opened and the outer duct (40), (41) or (42) blocked, and the full spring return of a displaced tappet will open the outer duct and block the inner duct. The partial return of a tappet, as a result of particle jamming, will leave both ducts blocked, however, and generate an appropriate error signal, as will the complete non-return of a displaced tappet.

Abstract: Self-twist plural yarn strands are produced by a system wherein at least two singles yarn strands are individually twisted to form twisted strands each having longitudinally spaced nodes. The strands are separately conveyed around a yarn wheel and brought together in a parallel relationship with the nodes of one strand substantially aligned with the nodes of each other strand. The corresponding nodes from one strand are fastened to those of each other strand by heating with an electric arc and the strands are removed from the wheel and allowed to ply. The node fastening means comprises a pair of electrodes and a circuit for supplying arc-producing voltage across the electrodes. One electrode is mounted on the wheel and extends diagonally across and under the node location. The other electrode is fixed adjacent the wheel so that the arc traverses the yarn as it passes from one end of the diagonal electrode to the other.

Abstract: This invention relates to a process for producing a curl shrunk silk yarn. One of the features of the invention is to absorb collagen derived protein into raw silk material after sericin is removed therefrom. Thereafter, silk fibers are twisted in a S- or Z-direction and then saturated with moisture. Another feature of the invention is to maintain the moisture saturated silk fibers at prescribed temperature and under prescribed pressure for a given time. Thereafter, the fibers are untwisted in the reverse direction and given a curl shrinkage characteristic under the circumstance of saturated vapor.

Abstract: Mechanical work and power transmitted through transmission elements such as chain drives is determined by deflecting a transmission element and measuring the distance and/or speed of deflection and the deflection force while the transmission continues its operation.

Abstract: A silicon junction diode is used as one element of a resistance bridge to rm the temperature sensing element of an electronic thermostat. Current through the diode is maintained at approximately constant value so that the negative temperature coefficient characteristic of the diode can be utilized. The values of the fixed resistors in the bridge are selected so as to provide a null at a preselected temperature. Used in conjunction with a voltage comparator circuit having positive feedback, a digital control signal is provided whenever the temperature of the sensing element rises above the preselected null value. The addition of a single NOR gate allows the combination of this digital control signal with an external control signal.
