Abstract: A modular wall structure can include a first modular unit having a first face defined by a first perimeter and a second modular unit having a second face defined by a second perimeter. The first modular unit can be operably and selectively coupled to the second modular unit. Base units can be provided to support the first and second modular units.

Abstract: In one embodiment, a braking apparatus includes a pair of brake shoes, a cam follower connected to at least one of the shoes, a compressible spring connected to the cam follower, and an actuation assembly including a motor, a ball screw and an electromagnetic clutch. The braking apparatus is operative to transition from a brake applied position where the brake shoes are closed and a brake release position where the brake shoes are separated. When the braking apparatus is in the brake release position, a brake application may be commenced to close the shoes by power no longer being supplied to the electromagnetic clutch. Additionally, when the braking apparatus is undergoing a brake release cycle to separate the brake shoes, the brake application cycle may also be commenced prior to completion of the brake release cycle when power is no longer supplied to the electromagnetic clutch and the motor.

Abstract: Various embodiments for a traction element used with athletic shoes having a stud body with a metal insert that extends axially from the stud body and methods for manufacturing such traction elements are disclosed.

Abstract: A jack stand apparatus has a frame having a first portion and an outwardly extending second portion, a barrel affixed to the outwardly extending portion so as to have a generally vertical longitudinal axis, a jack screw threadedly received by the barrel, and a plurality of caster wheels removably affixed to the frame. The barrel has an outer end extending outwardly for a first distance from the first portion of the frame. The plurality of caster wheels support the frame for a second distance from a level of the bottom of the caster wheels. The first distance is no more than the second distance. A support head is affixed to an end of the jack screw opposite the barrel. The frame is invertible relative to the caster wheels such that in one position the barrel extends upwardly from the frame and a second position in which the barrel extends downwardly from the frame.

Abstract: A rotary closure with a latching system that latches together the components of the rotary closure in a snap-fit engagement is disclosed. The latching system includes a latching extension defining first and second legs each defining a respective tang configured for coupling the latching extension to the distal-most keyway for assembling the components of the rotary closure together.

Abstract: Fluid delivery systems and methods for using fluid delivery systems are rotatable around two axes. In one embodiment, the fluid delivery system has a reduced swing radius and/or a reduced clearance area needed to rotate the fluid delivery device about one of the axes. The reduced swing radius and/or reduced clearance area allow for a more compact footprint of the fluid delivery system and a larger ratio of flow rate of fluid per unit of required clearance area.

Abstract: In an embodiment, a door detection system may include a transmitter, a receiver, a reflector, and one or more processors. The transmitter positioned on an elevator car door transmits a signal towards a reflector on a hoistway door and the reflector reflects the signal towards the receiver when the hoistway door is properly positioned with respect to the elevator door. The one or more processors determine whether the hoistway door is properly positioned with respect to the elevator car door based on the reflected signal received by the receiver. If the hoistway door is not properly positioned, the elevator car is prevented from moving. If the hoistway door is properly positioned, the elevator car is free to move.

Abstract: A vacuum tank semi-trailer having a horizontal tank with front and rear tank heads. A front cantilevered frame is welded to the front tank head and has a fifth wheel hitch and a pair of landing legs fixed thereto. A rear cantilevered frame is welded to the rear tank head, and has an axle assembly sprung therefrom. A lower center of gravity is realized by keeping the front a rear frames smaller than the diameter of the tank. A fill pipe having an upwardly sloped portion to clear the axle assembly is coupled to the tank and presents a fill connection at the rear of the rear frame in a protected manner.

Abstract: Various embodiments of a rotary closure with a latching system that latches together the components of the rotary closure in snap-fit engagement are disclosed.

Abstract: Various embodiments for a traction element used with athletic shoes having a stud body with a metal insert that extends axially from the stud body and methods for manufacturing such traction elements are disclosed.

Abstract: A shelf divider apparatus and a system thereof are disclosed herein. The shelf divider apparatus is configured to attached to a wire shelf including a front top rail, a front bottom rail, a plurality of balls separating the front top and bottom rails, and a plurality of support wires supported by the front bottom rail. The shelf divider includes a first end, a second end, and a first clip connected to and extending below and away from the first end. The first clip includes a plurality of receivers defined along a lower portion of the first clip and extending perpendicularly relative to a divider length. Straight slots are defined between adjacent receivers. Each straight slot includes an enlarged opening spaced apart from a straight slot entrance for accommodating a portion of one ball of the plurality of balls so that the plurality of receivers may engage the front bottom wire.
