Abstract: A box for ampoules has a front wall with a top edge well below the top edge of the rear wall so as to define (with side walls) an opening closed by a cover extending from the rear wall and overlapping the front wall to which it is secured by an adhesive edge. Lines of perforations across the overlapping portion define a web to be torn off when access is to be had to the ampoules. This leaves the remaining part of the cover with a tongue which, when the box is again to be closed, is tucked into a pocket between the front wall and a support for the ampoules which also strengthens the front wall. The support includes corrugated cardboard providing compartments for the ampoules. The tongue and top edge of the front wall are shaped to interlock.

Abstract: An energy conversion system for deriving useful power from the thermal gradients in the ocean, or from solar, geothermal, or other sources of low level heat, by using warm water to heat a confined working gas such as air whereby a pressure increase results due to warming the gas, arranging so that the expansion moves a piston or other device to extract power, and then cooling the gas and compressing it back to initial conditions while directly or indirectly contacting it with cooler water to thereby decrease the work needed for recompression. Net useful work results from the difference between the work of expansion at higher temperature and the work of recompression at lower temperature.

Abstract: A woven fabric for reinforcing a resilient material, such as a tire casing, wherein the warp of the fabric consists of substantially unstranded wires held together in spaced groups by the weft of the fabric with at least some of the wires being formed with a set so as to have undulations along their length to thereby improve the adhesion between the wires and resilient material as well as to improve the tensile and compression stress characteristics of the wires. The amplitude of the undulations may be perpendicular to the general direction in which the groups are spaced from each other. The undulations may also be periodic with the phase of such undulations being either the same or different between adjacent groups.

Abstract: At least two conductive wire elements which are separated from each other by a thin insulating layer such that as soon as a pressure is exerted on the composite wire at least one of the electrical characteristics, contact resistance and/or capacitance between the elements, changes to a measurable extent.

Abstract: Panels constructed from a light weight core bonded to specially shaped perimeter members such that the vertical members overlap and interlock with similar members on adjacent panels whereby transverse motion of adjacent panels toward the common center line serves to urge adjoining panels into close abutment, top and bottom runners with an elastomerically biased member mating with the horizontal perimeter members such as to grip the panels inserted between them while providing a centering force which serves to both align the panels and abut them to form a continuous batten free wall without the use of any other mechanical fastenings. Provision is made for locking the biased member in order to inhibit the removal of panels.Such demountable partition walls may be erected and dismantled without the use of tools or skills or interference with the building structure or furnishings.

Abstract: A novel gap type surge absorber is disclosed. The surge absorber comprises a plurality of carbon thin films isolated from each others at short distances attached to the surface of an insulating body and one material selected from the group consisting of a metal, an alloy and a conductive adhesive as an electrode fixed to each of the plural carbon thin films. The surge absorber is an element based on a new mechanism that when a surge voltage reaches a prescribed value, a discharge is generated owing to emission of electrons between the carbon thin films and thereby a creeping discharge is initiated between the electrodes. The surge absorber has a small electrostatic capacity as well as a small discharge lag and is capable of cutting off a follow current.
