A chassis (1) for a rail-bound transport vehicle for transporting goods, in particular in intralogistics. The chassis (1) has at least one chassis axle (2) and at least one load-bearing roller (3) configured for rolling on a rail (4) that is rotatably supported on a pivot arm (5) about a roller rotation axis (6) and the pivot arm (5) together with the roller (3) is pivotably supported by a pivot joint (7) on the chassis axle (2). The pivot arm (5) is additionally supported by a support bearing (8) on the chassis axle (2) and the roller (3) is arranged between the pivot joint (7) and the support bearing (8).

A transport chair of this disclosure includes a frame having a pair of fixed sides and hinged sides, the frame moveable between stowed and deployed states. The frame includes wheel receiving means and armrest and push handle assemblies receiving means with quick connect-disconnect clamps or pins. A bar, which is connectable to, and detachable from, each hinge extends between the pair of hinged sides. When connected to the hinged sides, the bar locks the frame in the deployed state and prevents the frame from moving to the stowed state. The chair may be quickly assembled and then dissembled for storage without the need for tools. When dissembled, the transport chair fits within an within an envelope 9 inches deep×14 inches wide×22 inches long.

A roller has a wheel, a wheel axle and a pin which protrudes upward from a housing of the roller. A sleeve sits on the pin and is spaced apart from the pin radially and axially upward by a damping material arranged between the sleeve and the pin, the damping material being arranged so that all axial and/or radial contact between the pin and the sleeve is prevented. Alternatively, an attachment damping part can be arranged on a pin of the roller in overlap with the pin, wherein the attachment damping part has an inner sleeve and an outer sleeve, the inner sleeve being spaced apart radially and axially upward by a damping material arranged between the inner sleeve and the outer sleeve. The damping material is arranged in such a way that all axial and/or radial contact between the inner sleeve and the outer sleeve is prevented.

The shopping cart security system is configured for use with a hand propelled vehicle known as a shopping cart. The shopping cart security system is a wheeled structure that allows the hand propelled vehicle to roll over a supporting surface. The shopping cart security system: a) determines the GPS coordinates of the shopping cart security system; b) compares the GPS coordinates of the shopping cart security system with a previously determined set of GPS coordinates that determine an operating perimeter for the shopping cart security system; and, c) disables the rotation of the wheeled structure that forms the shopping cart security system when the shopping cart security system is determined to be outside of the region bounded by the previously determined operating perimeter.

The present invention relates to stabilization of RNA, in particular mRNA, and an increase in mRNA translation. The present invention particularly relates to a modification of RNA, in particular in vitro-transcribed RNA, resulting in increased transcript stability and/or translation efficiency. According to the invention, it was demonstrated that certain sequences in the 3′-untranslated region (UTR) of an RNA molecule improve stability and translation efficiency.

A laundry treatment apparatus including a plurality of swivel casters. Two of the swivel casters are braked swivel casters. One of the swivel casters other than the braked swivel casters is a vertically adjustable swivel caster. The braked swivel casters restrain translational movement of the laundry treatment apparatus across a floor. The vertically adjustable swivel caster can help fix the position of the laundry treatment apparatus so as to restrain rocking and twisting of the laundry treatment apparatus.

A safety wheel incudes: a ring-shaped main wheel; an inner frame positioned inside the main wheel, wherein the inner frame comprising at least two auxiliary wheels that come into contact with an inner surface of the main wheel and rotate when the main wheel is driven; and a sliding block provided to be movable under the guide of the inner frame.

An anti-rolling wheel includes: a ring-shaped main wheel; an inner frame positioned inside the main wheel, wherein the inner frame comprising at least two auxiliary wheels that come into contact with an inner surface of the main wheel and rotate when the main wheel is driven; and a sliding block provided to be movable under the guide of the inner frame.

An autonomous mobile device may use a pair of main wheels and a caster assembly to provide mobility. The main wheels are driven by motors, providing steering and movement. Each main wheel may include a cover that conceals and protects a hub of the main wheel from the external environment. The covers may be held in place by elastomeric posts, allowing easy changeout. The caster assembly has a minimal overall height and a field replaceable caster wheel. The caster wheel may include a target that is detectable by a non-contact sensor to detect caster wheel rotation. The caster wheel may comprise an axle, caster wheel hub, and a pair of caster wheel endcaps on each end of the axle. A set of features on the caster wheel hub and each of the caster wheel endcaps provide a labyrinthian path that prevents debris from fouling around the axle.
