The corner stiffening element for a cardboard box has two mutually perpendicular longitudinal walls (1,2) and transverse end walls (5,6). The lower wall (6) abuts on the bottom in a box in which the element is positioned and the upper wall (5) forms a stop for a box stacked on top of the box in which the element is placed. The corner element comprises a hook (3) which is carried by a heavy base pa...

A vibration wave driven motor produces a travelling wave in an elastic body and thereby moves the elastic body relative to a member pressed against the elastic body. The travelling wave is a combination of a plurality of standing waves generated by application of out-of-phase alternate electric fields to a plurality of driving element groups for an electro-mechanical energy conversion element bond...

A micropanel for the delivery of gas from a supply cylinder (7) to a tool location comprises an arrangement of valves (1,3,4,5), pressure regulator (2) and associated components adapted to enhance the purity of the delivered gas and the safety of the gas delivery panel.

This invention embodies a Vertical Cavity Surface Emitting Laser with a top mirror (10) comprising at least one pair of quarterwave layers, each pair consisting of a low index of refraction layer and a high index of refraction layer, the high index of refraction layer being a semiconductor chosen from GaP and ZnS and the low index of refraction layer being chosen from borositicate glass (BSG> CaF2...

The system storage device (1) is divided into regions or sectors (2). Each sector represents a complete description, picture or film of an object or region. Each sector has a code or recognition mark related to the object and the coordinates of the region. When the guide is required to present the information, the region coordinates are entered into the system and evaluated. They are then compared...

A telescoping mast assembly comprises tubular mast sections which are square in cross-section and a drive assembly for actuating the sections along a path between extended and retracted positions. The drive assembly comprises a tubular drive member connected to one of the mast sections for extending and retracting the mast sections, a take up reel for storing the drive member and a drive motor for...

The method comprises the step of applying a flexible outer barrier layer to at least that part of the object most vulnerable to dacay, providing a bituminous substance between the barrier layer and the object and heating the barrier layer so as to melt the bituminous substance sufficiently for it to bond intimately to the wooden object. The barrier layer may be a plastics film of heat shrinkable p...

A computer controlled system includes a processing architecture. The processing architecture provides for application programs to be executed as cooperating processes interacting with each other, with a control system and with the world outside this architecture. Process instances (Sender, P1, P2, P3) are distributed over control system processors (CP1, CP2, CP3) by means of distribution units (A-...

A paint ball including a paint ball shell and an axis extending through the shell to define first and second poles. The paint ball shell fractures in a predetermined pattern upon the receipt of a fracturing force to form fracture lines from the point of impact circumferentially toward the first pole and from the point of impact circumferentially toward the second pole.

In a mineral wool insulation board stiffened by an open-pore, flat formation, the open-pore formation is embedded in the surface of the insulation board with positive locking, the mineral wool being pressed into the cavities of the open-pore formation in the surface area of the insulation board.

Process and appts. for chemically/morphologically converting asbestos and building materials contg. asbestos are claimed. The novelty is that the asbestos or asbestos-contg. materials are treated in a system free from organic components with aq. colloidal dispersions of amorphous SiO2 consisting of non-crosslinked spherical individual particles having OH gps., with liq. consistency and free from s...

The highly polished surface of the floor covering (3) is made additionally slip resistant. It has friction values of greater than 0.40 between shoe sole and floor surface. The surface has a statistically spread out but irregular arrangement of indentations which are invisible to the naked eye but are lens-shaped, sharp-edged, as flat as possible in the form of micro craters with a suction pad type...

Analog or digital systems (10) and methods generate a composite signal derived from a biological event in a time sequential fashion.
