Abstract: ABSTRACT OF THE DISCLOSURE A method and a restraining device for improving both arm and leg strokes of a swimmer are provided.  The restraining device comprises first and second band members each adapted for securement to an arm or leg and an elongated chain connecting the band members together.  An attaching clip can be provided on each band member for engaging a selected link in the chain whereby the point of attachment of the chain is adjustable.  When the device is used on an arm, one band member is attached to the wrist and the other is attached to the upper portion of the arm.  One restraining device is used on each arm so that each arm is prevented from being straight-ened as the arm is lifted out of the water and is retained in a desired position as the arm re-enters the water.  When the device is used on the legs, one band member is attached to one leg and the other is attached to the other leg, the point of attachment in each case being just below the knee.  The legs are thus kept close together and the stroke of both legs is limited.

Abstract: ABSTRACT:         The invention relates to a sunlamp device which is provided with a high pressure mercury vapour discharge tube and with an auxiliary device for exting-uishing the discharge tube with a given time delay on termination of the desired irradiation period.         According to the invention a switch connected in series with the discharge tube is shunted by  a resistor having a positive temperature coefficient of resistance (PTC resistor). This ensures that after the switch has been opened on termination of the desired irradiation period the PTC resistor passes current for some time. As a result the resistance of this PTC resistor is increased, which causes the current through the discharge tube to be reduced. This finally results in an increase of the operating voltage of the dis-charge tube to a value higher than the available voltage, so that the -tube is extinguished. This device is simpler than a known device provided with two timers.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved easy open end closure, characterized by the provision of improved pull tab positioning means for maintaining the pull tab in a desired orientation relative to the flap defining score line, regardless of doming of the end panel.  The finger ring portion of the tab is nested within a recess formed in the end panel. A protrusion, formed interior to this recess, abuts the interior periphery of the finger ring, serving as an anti-rotation abutment.  The tab rivet panel is formed at an angle to the plane of the tab, inclining 4-6° away from the end panel center, whereby a panelward bias is imparted to the finger ring portion of the tab by the tab attachment rivet.  This bias serves to retain the finger ring within the recess.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for packaging compressible fibrous batts and a package of same are provided.  The batts are formed by severing a longitudinally-extending strip of compress-ible fibrous material into batts of discrete lengths with the batts then being collected in end-to-end relationship.  The batts are then moved into a loop of a packaging machine, which loop is formed by a belt maintained under controlled tension.  The batts are fed longitudinally in abutting, end-to-end relationship into the belt loop which places them under compression as they are wound into a package, with the loop gradually expanding in diameter as the package size increases.  Tapes are placed directly around the outermost batt to hold the package in the compressed state and the completed package is then discharged from the machine.
