A heat-recovery unit includes an outer housing and a heat-recovery cell with two separate air passages therethrough opening on faces of the cell. The upstream face of each passage is adjacent and inclined at 90.degree. to the downstream face of the other passage. A turret on the housing at each inlet and outlet is rotatable about its axis and has an angled coupling rotatable on the turret about an axis at right-angles to the axis of the turret. The inlet, upstream turrets each contain a filter a...

A bedding unit utilizes formed wire springs for supporting a wire grid on a frame. A spring has an upper portion which has two transverse bars, a longitudinal center bar located between and spaced from the transverse bars, and connecting sections which connect the opposite ends of the center bar to the ends of the transverse bars. Under compression, the upper portion of the spring or a grid wire attached thereto contacts a torsion bar in the spring. Some embodiments have a continuous and uninter...

The invention discloses a spring unit for use in a sprung unit such as a bed, divan bed, mattress, or other upholstered unit, the spring unit comprising a pocket of fabric or other suitable material and having at least two sub-pockets, each of said sub-pockets containing a resilient member. The pocket will preferably be divided across, laterally, or diagonally so as to form said at least two sub-pockets. The spring unit may be formed with two sub-pockets or three or more sub-pockets each contain...

A conveyor roller has end caps forming housings for ball bearing units rotatably mounting the conveyor roller on a spindle, each housing having an end wall forming an abutment for locating the bearing in the housing, and the spindle having circlips abutting the bearing units. Each bearing unit has inboard and outboard seals mounted on the outer bearing ring, and the inboard seal is formed with projections which are compressed axially with permanent deformation between the inboard seal and the en...

A spring unit (2) for incorporation into a bed, divan bed, mattress, or other upholstery unit comprises a first spring (4) and a second spring located (6) within said first spring (4). The first spring (4) may be a pocketted spring, or the second spring may be a pocketted spring, or both of said springs may be pocketted springs, the pockets of said pocketted springs being composed of a woven material and/or a synthetic material.

An apparatus for transferring products, in particular eggs, comprising at at least one height, positioned under an endless sorting conveyor, at least one row of conveying units, wherein the products are discharged in a well-defined manner from the sorting conveyor into the conveying units, are received by the conveying units, and are subsequently delivered to a packaging device thereunder, while each conveying unit is provided with at least a first and a second part which can move relative to ea...

A control unit for use in a window blind head rail assembly includes a sprocket wheel, a chain guard housing, a sprocket support and wrap spring, a splined bush for engagement with a roller blind tube and a center pin, wherein the center pin has a center-pin head and a body, the center-pin head including one or more fins adapted to co-operatively engage with one or more recesses in the sprocket support.

The invention provides a self-powered display unit for displaying at least two consecutively changing images to be viewed by a viewer, the unit comprising a housing, at least one wall portion of the housing being made of an array of linear lenses having a lenticular front face and a flat rear face; at least one displaceable, light-weight, substantially planar indicia carrier disposed inside the housing at a distance from the rear face at most equalling the focal length of the lenses, and a high ...

The accommodation unit described carries on its underside a circular array of wheels which rest on a circular rail. Mounted on the platform are three separate room units. Each room unit has a generally circular wall and the circumferences of the walls of the three rooms intersect one another to provide a common space between the rooms to allow access to the rooms and to accommodate a central hollow service pillar which is coaxial with the rotary axis of the platform.

lighting unit includes a circuit board having a number of LED packages extending outward from a front side. The printed circuit board is covered by a transparent cover, forming an outer cavity between the cover and the printed circuit board. The printed circuit board is supported by a housing, in which a second cavity is formed. In a first embodiment, the circuit board, being flexible, is wrapped around a cylindrical housing, with LED packages being directed radially outward. In a second embodim...
