Abstract: A utility tool having a plurality of elongated channels extending the length of a body member. Each tool is provided with a threaded member for selectively locking the tool in a retracted position, an extended position, or a position in between. A central channel is provided which is of a configuration to accept a sliding knife blade or a tool implement of the same cross sectional configuration as is carried by the outboard channels.

Abstract: A knife having a sliding blade which may slide from a retracted position to an extended position. A locking member is pivotally connected to the blade and travels with the blade as the blade moves within a handle. A finger on the locking member engages with a recess to selectively lock the blade within the handle. By rocking the locking member forward, against the pressure of a spring, the blade is pushed outwardly from the handle until the finger automatically seats in an extension notch provided in the handle. Retraction of the knife is accomplished by rocking the locking member forward and pulling rearwardly thereon to force the blade back into the handle. A sheath for the knife engages the locking member to automatically lock the knife within the sheath upon insertion into the sheath. Upon extraction of the knife from the sheath, the blade is automatically extended.

Movably connected to the first member is a second member which may be moved outwardly from the top of the can by pivoting or sliding such that a portion of the second member extends beyond the edge of the can. A fastener is provided which allows lateral movement of the second member with respect to the first member, but fixes upward movement of the second member with respect to the first member such that the first and second members move together when the second member is lifted, thereby increasing the available leverage for opening the can.

Abstract: A door locking system for attachment to an outwardly opening door which engages the door frame and which has a panic bar movable towards the door for disengaging the locking system. The locking device includes an outer sleeve fixedly mounted to the interior surface of the door and extending over one side of the door frame. An inner sleeve is provided within the outer sleeve which is pulled outwardly to a door frame engagement position, wherein the inner sleeve extends over the other side of the door frame to prevent the door from being opened. Movement of the panic bar towards the door causes the inner sleeve to retract into the outer sleeve, thereby allowing the door to be opened. A reset system is provided for automatically resetting the lock when the door is closed.

Abstract: A receptacle power indicator for use in connection with a receptacle. Contact members are provided on the sides of a receptacle and provide contact surfaces laterally displaced from the receptacle.

Abstract: A bearing device for use in textile drafting roller pairs for supporting the top roller of a drafting roller pair. The bearing device finds particular use with magnetic drafting rollers, but can be used with other types of roller configurations. The bearing device allows for the top roller to be selectively positioned with respect to the bottom roller in order to allow removal of the top roller and to prevent deformation of cots or aprons provided thereon during machine stoppage. A rotating debris excluding interface is also provided through interaction of the bearing device and the end of a roller. Handles are attached to the bearing device for allowing extraction of the top roller from a roller pair, and ribs may be provided on the bearing device or receptacle therefor to facilitate piecing up of a broken yarn. Related methods of use of the bearing device are also disclosed.

Abstract: A magnetic roll for use in roller pairs of a drafting system on a textile machine. Each magnetic roll includes a central pole member having a rare earth magnet positioned on either side thereof. An end pole member is provided adjacent each magnet, and a cot is provided next to each end pole member for gripping and propelling fibers between the roller pairs of the drafting system.

Abstract: A folding knife having a blade and a longitudinally extending liner. Pivotally connected to the liner is a blade holder receiver, or shell, which receives the liner when the blade is in a retracted position, to cover and retain the blade within the liner. The liner is also received by the shell when the blade is in the extended position, and through cooperation of the shell with the blade and the liner, the blade can be locked in its extended position. The knife may be opened and closed using one hand, and a sharpening device is provided for attachment to the liner and shell for sharpening the blade.

Abstract: In a mixing and opening device for pneumatically supplied flocculent fiber material, wherein fiber material is fed, by use of transport air and through a supply conduit, to a blow-in chute section of a hopper, wherein said blow-in chute section comprises a screen means for separating the fiber material from the transport air, and an air collecting chamber arranged behind said screen means for discharge of the transport air, and wherein, on the lower end of said hopper, the fiber material layered in said hopper can be fed via an intake means to an opening means, it is provided that the intake means comprises two intake rollers of different sizes.

Abstract: In a nonwoven laying device having at least two reciprocating carriages to be accelerated at the reversal points of their moving path, namely an upper carriage and a laying carriage, and having at least two circulating conveyor belts to be guided by guide rollers of the carriages, namely a main conveyor belt and a guiding conveyor belt, the upper carriage having at least two guide rollers. The guide rollers are laterally displaced and are set at different elevations so as to form a descending path for at least one of the conveyor belts. The path having an acute angle to the horizontal. Both belts facing each other forming an opening angle from 20.degree. to over 90.degree.. The angle is adjustable through adjustable rollers in the carriage.

Abstract: A folding knife having an elongated, unitary blade carrier which is received within a blade carrier cavity of a unitary molded handle. The metal construction of the blade carrier provides a rigid, hidden frame structure for strengthening the knife. The combination of the unitary handle and unitary blade carrier allow for simplified construction. Covers are also provided in the handle for concealing a blade pivot pin.

Abstract: An autoleveller derives the signal for its draft correction from an averaged value of the sliver weight or thickness signals in each of a plurality of unit lengths of the sliver path. A preferred embodiment uses upstream and downstream sliver weight or thickness measuring means to derive signals for a draft correction and the gain of a draft correction made in response to the first sliver measuring means is varied in response to the averaged signal from the second sliver measuring means.

Abstract: A knife/sheath locking assembly for locking a knife on either side from accidental disengagement from within a sheath.
