Abstract: Abstract of the Disclosure A power supply and firing control circuit for a strobe lamp has a capacitor means for providing electrical power to the power electrodes of the strobe lamp for discharge through the strobe lamp.  A transformer has a pair of secondary windings, one of which is connected to each of the power elec-trodes of the strode lamp in series with the capacitor means. The firing pulses provided by the secondary windings of the transformer are of opposite electrical polarity.  The absolute voltage differential between any portion of the circuit and ground potential will be minimized and energy losses thereby reduced.  Additionally, the circuit provides substantial improve-ment in ionization effectiveness, thereby permitting the secondary turns of the transformer to be reduced in number and the trans-former size and weight reduced correspondingly.

Abstract: ABSTRACT A web-seam closure is formed by ultrasonic welding in a gable top box fabricated from thermoplastic coated material.  During welding, the areas to be welded are held together not only at the seam but also at a location between the seam and the side of the box.  These areas are held together also during a subsequent cooling period.  Thus, the resilience of the box material is prevented from opening the seam during or immediately after the welding operation.  The anvil is preferably arched transversely of the seam so that softened thermoplastic material is squeezed out to form a bead along the inner edge of the seam.

Abstract: STRAIN-RELIEF MEMBER FOR REDUCING TORSIONAL STRAINS IN LINE CORD OF A PERSONAL CARE ELECTRICAL APPLIANCE                INVENTOR: ROBERT R. KING         ABSTRACT OF THE DISCLOSURE              A strain-relief member is provided to relieve tor-sional strains from a two-conductor power supply cord attached to a personal care electrical appliance, such as a hand-held hair dryer, or curling iron.  Such torsional strains are primarily those resulting from twisting the wire about its longitudinal axis, as when using a curling iron, rather than from flexing.            The strain-relief member is an elongated body of elastomeric material molded about the usual two-conductor line cord.  It has a lateral projection or collar on one end thereof adapted to fit into the interior of the personal care electrical appliance to prevent rotation with respect to the appliance.          The outer portion of the body member is uniformly tapered along its length on the sides adjacent to single conductors of said cord and has flattened, generally parallel sides extending along the opposite sides which are adjacent to both conductors of the power supply cord.            The strain-relief member distributes such tor-sional bend and flex forces substantially uniformly along the length of the member by providing a uniform are along that portion of the wire which is flexed as a result of application of torsional strains, thus preventing fracture of the power supply cord.

Abstract: ABSTRACT OF THE DISCLOSURE This invention provides a process for applying finish to a yarn running at least 2500 meters per minute. The finish is metered through a passageway just prior to application to the yarn. The yarn has entrained therewith turbulent air and the process is characterized by inhibiting the variable influence of the turbulent air travelling with the running yarn upon the finish in the passageway. The process overcomes the erratic results frequently obtained with other methods of applying a finish, such non-uniform and erratic results causing processing problems in subsequent operations on the yarn, as well as causing defects in products made from the yarn.

Abstract: "APPARATUS TO MONITOR ELECTRICAL CABLES, INCLUDING SPLICE  JOINTS AND THE LIKE, FOR THE INGRESS OF MOISTURE"        ABSTRACT           The invention relates to the monitoring of electrical cables for the presence of moisture within the cable system.  A means is disclosed whereby an electrical cable system is electronically monitored and the condition of the electrical cable system continuously signalled to a remote equipment office.          Should moisture enter the cable at a breach in the physical outer protection, an alarm is signalled remotely and the location of the breach is identified.          The electronic monitoring and protection system described may be used on conventional telephone cable to monitor splice points, repeater sites and other critical locations or on specially designed cable to monitor the cable system along its entire length.  As the invention thus described is electronic by design considerable flexibility exists for application in any physical system where the environment is of concern to the integrity of the system.
