Abstract: A handle assembly for a luggage case having a hand-grip member made of a single piece of strap folded longitudinally into multiple layers so as to form flat slots at opposite ends, through which coupling loops extend for joining the hand-grip member to anchor clips attached to the frame of the luggage case. The coupling loops may shift inwardly and outwardly in the flat slots to enable the hand-grip member to assume an upper or a lower position. The single piece of strap forming the hand-grip member has a longitudinal coextensive strap or wire of semi-rigid deformable metal embodied in the strap, which permits flexible deformation of the hand-grip member optionally into an arched or curved form in which it remains for use in carrying the luggage case, or into a flat or depressed form for storage or shipment in close side-by-side relation to other luggage cases. A number of combinations with several devices for attaching the hand-grip member to the body or frame of a luggage case are disclosed.

Abstract: Back-pedal brake operator for multi-speed bicycles in which the brake operating action is obtained by turning the foot pedals rearwardly a short distance from any position which the pedals may occupy at the instant when the driver wishes to apply braking action, the braking operation being obtained without utilizing the sprocket chain to apply the braking force, and the brakes are automatically released without any "lock-up" effect when the driver starts pedaling forward in the normal manner. The back-pedal operators shown are directly associated with the sprocket assembly as a compact self-contained unit integrated therewith and can be installed as original equipment by bicycle manufacturers or can be retrofitted by bicycle shops or owners on existing multi-speed bicycles. The bicycle is permitted to be wheeled freely rearwardly without the brakes becoming applied.

Abstract: During the manufacture of bricks, either before or after such bricks are introduced to the kiln for drying, selected brick from spaced positions in at least some of the rows are mechanically displaced to corresponding positions in upstream, downstream, or otherwise adjacent rows to effect an inter-row movement of some, but fewer than all of the bricks in any particular row. According to the invention, the selected bricks may be either pushed, lifted, lowered or combinations thereof from one row and transferred to a different row. One translating device designed for this technique is a snaggle-tooth pusher which engages and pushes some, but not all of the bricks in a row or rows. The selected bricks may be initially separated from the other bricks by means of either the snaggle-tooth puller, or by means of a vertically movable support plate which operates in conjunction with a slotted support plate immediately thereabove to remove and lower selected brick.

Abstract: A method of and apparatus for making a concave bottom on a blown thermoplastic container, and a container having such a bottom. A blowable pre-form is initially expanded against a composite mold surface defined by the end faces of a plurality of concentric tubes surrounding a central actuating rod. The rod and the tubes are initially telescopically positioned to define a composite concave surface, so that a first convex bottom is blown. Subsequently, the rod and tubes are actuated telescopically to progressively invert the convex bottom to a concave shape. The end faces of the tubes may be grooved to define reinforcing ribs in the concave bottom wall, if desired.The container has a concave bottom wall of improved resistance to deformation under internal pressure. This is accomplished by forming a support ring at the juncture of a pair of oppositely directed inner and outer bottom walls, the juncture of the walls defining an included angle which is equal to or less than 90.degree.
