The box housing side walls (11) include hinged lid panels (17,18) adapted to be folded down onto the top wall (3) of the expansible vessel (1) when the expansible vessel is retracted in order to serve as a floor for the solid bulk cargo.
Patent CA-2039993-A1 (CA)
Inventor: MARCO LESLIE S
IPC: B65D67/02
Filed: 1991-04-08
Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles.  For each carrier, integrally joined band segments define container-receiving apertures.  Moreover, an integral handle is joined at its ends respectively to middle portions of two outer segments, which are joined to one cross segment at a node.  Stresses are distributed from each end of the handle, through the outer segment having such end joined to a middle portion thereof, to two cross segments. Perforated lines divide alternate cross segments into half segments and facilitate severance of such stock to form the individual carriers.  Each half segment has an aperture-defining edge configured to provide means, which may comprise a nub, for countering tendencies of such half segment to neck down or to break.  The handle has a middle leg, which is joined to the node via a frangible joint, as defined by a perforated line extending across the middle leg.  The frangible joint is designed to break away when stressed.

Title: Methods for manufacturing foamable metal bodies
Inventor: BAUMEISTER JOACHIM
IPC: C22C1/08
Filed: 1991-06-07
Abstract: A method is described for manufacturing foamable metal bodies in which a mixture (17) of a metal powder (15) and a gas-splitting propellant powder (16) is hot-compacted to a semifinished product (19) at a temperature at which the joining of the metal powder particles takes place primarily by diffusion and at a pressure which is sufficiently high to hinder the decomposition of the propellant in such fashion that the metal particles form a solid bond with one another and constitute a gas-tight seal for the gas particles of the propellant. The foamable metal body can also be produced by rolling. In addition, a use of the foamable metal body (19) thus produced for manufacturing a porous metal body (21) is proposed.

Title: Hub-mounted vehicle back-up alarm
Inventor: HUTCHISSON JAMES
IPC: B60Q1/22
Filed: 1991-06-12
Abstract: A self-powered back-up alarm for mounting to the wheel hub of a heavy truck or like vehicle. The alarm includes a housing adapted to be mounted to a vehicle wheel hub. Inside the housing is a magnetized stator that is held stable by a counterweight mounted for free rotation to a spindle in the housing. Also mounted in the housing is a power supply including a coil positioned adjacent the stator in the housing and attached thereto so that it rotates about the stator when the wheel hub turns. A battery stores the energy developed across the coil when the wheel hub rotates. Also mounted inside the housing are sensors located adjacent the stator that similarly rotate with the wheel hub. The sensors, in combination with an associated detect circuit, produce a reverse motion signal whenever the vehicle backs up. An audio alarm, located in the housing, is actuated by the reverse motion signal and emits an audible warning whenever the vehicle backs up.
