An integral irrigating conduit is provided for delivering a flush of water to the surgical working area as required for cleaning.

Abstract: A nose guide device is disclosed for a heddle frame of a weaving loom which operates as a guide to maintain adjacent heddle frames separated during shedding wherein ends of a front and back side of the device are split and uniquely constructed to interlock with an open slot in a frame slat of the heddle frame for quick and convenient installation and removal.

Abstract: A knotting mechanism for use on open-end spinning machines for performing a knotting process on yarn produced on machines. The knotting mechanism is mounted so that it can be moved longitudinally along the spinning machine and transversely to the spinning machine to a knotting position. A switch-on mechanism is activated responsive to the knotting mechanism being moved transversely to the spinning machine to a knotting position. A driving mechanism is provided for initiating the knotting process on the yarn upon being activated. A release mechanism is operably connected to the driving mechanism for activating the driving mechanism responsive to the switch-on mechanism being activated. A timing device de-activates the driving mechanism after a predetermined period of time sufficient to carry out the knotting process and prevents the driving mechanism from initiating another knotting process without the switch-on mechanism being further de-activated and re-activated.

Abstract: A woven electrical multi-conductor cable is disclosed having alternating longitudinal sections having generally flat and round configurations wherein the flat section affords binding of the conductors in fixed locations for convenient termination and uni-directional routing and wherein conductors are harnessed in the round section in random order for gimbal flexibility affording omni-directional routing of the cable in the round section.

Abstract: A supportive framework is disclosed for a boat having a hull which consists of a flexible plastic skin wherein the bottom frame element of the frame network is tubular and includes a rounded bottom wall which flexes inwardly to absorb stresses upon impact and more widely and uniformly distribute the stresses over the impact area.

Abstract: The invention relates to a release device for effecting the automatic rapid braking of moving machine parts, particularly of looms, which includes a braking actuating linkage subject to the action of force in the direction of actuation and maintained locked when the brake is released during machine running operation, and an electromagnet for unlocking the braking actuating linkage, energization of which is controlled by signals from monitoring members produced in case of breakdowns.

Abstract: A method of improving the dimensional stability, crease resistance and surface appearance of fibers, fabrics and textile products of cotton, polyester-cotton blends, polyesters and polyester-synthetic blends comprises applying to the fiber, fabric or textile product, to a level of 2-4% by weight of added solids, a resin obtained in a two-step process from phthalic or isophthalic acid, trimethylolpropane and trimellitic anhydride and an alkanoic acid of 10-20 carbon atoms or a polyether glycol of molecular weight 500-700 and neopentyl glycol.

Abstract: An elongated suction air nozzle provided for forming a thread reserve in the form of a loop in thread running past the mouth thereof. A constriction is provided in the nozzle and extends for the whole length of the expected loop size. The constriction divides the cross-sectional area of the nozzle into two partial areas resulting in air flow in the central region of the nozzle being of a greater velocity than in the two partial remote areas.

Abstract: A method and apparatus for the elimination of an irregularity in a yarn being produced on an open end spinning machine and drawn off therefrom by a pair of draw-off rollers and wound on a bobbin. The yarn is deflected into an N-shaped run so that a knotting mechanism can knot the parallel portion of the yarn together so as to remove the irregularity in the yarn. Yarn guides are provided on the knotting mechanism for displacing an oblique portion of the yarn out of the knotting mechanism when in use.

Abstract: It has been found that domestic turkeys raised for food processing may be skinned with feathers on for processing the skin into exotic leather having areas or patterns of raised folicles, or puckered portions with such patterned areas themselves displaying an unexpected pattern therein as opposed to a regular or random spacing. The natural puckers are further enhanced by shrinking subsequent to feather removal to raise the pattern while the turkeys thus skinned are processed into food.

Abstract: A filter for removing solids from a liquid of the type wherein a rotatable basket or drum has media inside straining from inside out. A power operated conveyor is mounted in the drum above the axis of rotation for receiving and positively removing solids. Thus, a liquid level is possible above the axis of rotation but below the conveyor so that a large filter area is in contact with the liquid while not interfering with the operation of the conveyor. A retractable scoop is provided for positively delivering the solids to the conveyor.

Abstract: A bulk yarn formed from a plurality of multi-filament yarns having alternating compact and open segments. The compact segments include first and second plaited portions which are twisted in opposite directions. The open segments of the yarn are defined by loosely bundled multi-filament yarn. The apparatus for bulking the yarn includes an elongated housing having a longitudinal bore extending therethrough. Pressurized air passes through diametrically opposed passages for contacting the yarn as it passes through the bore for producing the bulking effect thereon.

Abstract: A mounting for the shaft of an open-end spinning rotor which by means of axial thrust is pressed at its end against a ball that is carried by a unilateral attached support. A stablizing screw contacts the support in a direction opposite from the direction of the axial thrust of the shaft on the support.
