Abstract: ABSTRACT           A putter shaft has a lower end portion extending angular-ly relative to the shaft longitudinal axis and is slidably engageable with a guideway in the top of a removable putter head.  The guideway extends substantially the length of the putter head and includes an entry at one end portion and a stop at the opposite end portion. The guideway is selectively oriented relative to a striking surface of the putter head so that when a shoulder on the shaft lower end portion abuts the guideway stop, the putter head is in the desired spatial relation with the putter shaft. Cooperating releasable locking devices carried on the lower end portion of the putter shaft and within the guideway of the putter head engage to secure the putter head to the shaft when the putter head is in the operative position on the shaft lower end portion.  The cooperating locking devices are easily disengaged to facilitate disconnection of the putter head from the shaft for change of putter heads of different weight and configuration on the shaft, or change of different types of shafts for one or more types of putter heads.

Abstract: ABSTRACT      A process in the  forming of a  paper web,  the dewatering of the pulp web, and of the paper web being formed comprises feeding the pulp suspension jet from the slice of the headbox into a gap formed by two wires,  the gap becoming narrower in the feeding direction of the pump suspension jet.  Water is removed from the pulp web when the web is in compression between the carrying wire and the covering wire within the twin-wire forming zone, which begins immediately after the feeding gap.   The twin-wire forming zone is curved towards the loop of the carrying wire with a curve radius which is selected large enough so that the wire tensioning pressure resulting from  it and acting upon the pulp web becomes low and the water removed from the pulp web is not splashed from the inside surface of the wire loop by the effect of centrifugal force depen-dent upon the curve radius.  The joint run of the wires is passed over an open-surfaced forming roller, so as to be curved within a relatively small angle towards the loop of the covering wire.  The joint run of the wires is passed over a forming roller, so as to be curved towards the loop of the carrying wire.  The formed web is detached from the wire and transferred into the press section of the paper machine.    A  specifically  structured  twin-wire  former carries out the process.

Abstract: ABSTRACT OF THE DISCLOSURE        Non-woven, bias laid fabrics, where the various fabric layers are held together by external means, such as stitching and wherein, preferably, at least two of the layers are formed at an angle of from 30° to 150° relative to the long axis of the fabric, are formed by directing at least two pluralities of yarns back and forth across the width of the forming fabric, to be wrapped around or mounted on a series of needles formed on a moving conveyor, one conveyor being placed on either side and moving in the direction of the long axis of the fabric.  Speed of movement of the yarns can be determined by the speed of movement of the mechanism for the machine operated to hold the various fabric layers together; preferably said machine mechanism moves more slowly near the ends of each cycle so that yarn carriers are similarly slowed at either end of the forming fabric width, aiding in making successive courses of yarn lie parallel to each other without the necessity for extra equipment.  In one embodiment of the invention, the yarn carriers are provided with means to propel them in a direction generally away from the bonding portion of the machine to further assure the parallelism of successive courses of yarn.  It is not necessary that the number of needles correspond to the number of yarns.
