Title: Modular inflated supporting structure
Inventor: WALTERS BRIAN J
IPC: B65D81/07
Filed: 1992-12-02
Abstract: A modular supporting structure for positioning and supporting a product within an outer packing container, is disclosed. The product to be supported has predetermined external dimensions, and the outer packing container forms a chamber of predetermined internal dimensions. The supporting structure is formed from a plurality of modules, each module in turn comprising an air bladder for receiving and retaining air. The air bladder has a first compartment and a second compartment that are in fluid communication one with the other via a restrictive air passage that limits the rate of flow of air therebetween, thus providing physical damping for the product being supported by the modules. There is a connecting portion in the form of a flange, which is attached to the air bladder, that allows the modules to be interconnected one with another. When the modules are connected one to another, a product receiving socket is formed. The product receiving socket is shaped to fit the predetermined external dimensions of the product.

Patent CA-2138416-A1 (CA)
Inventor: ANDRUS PAUL G
IPC: G02B5/02
Filed: 1993-04-02
Abstract: An article for presenting dye/pigment images therein comprising a substantially transparent viewing region (20); photode-veloped, printed, deposited or diffused dyes and/or pigments (21) in the viewing region; and a substrate region (22) adjacent to the viewing region. The outer surface (23) of the viewing region is configured in a relief pattern comprising microscopic, smooth, share pyramids (31), cones (48), or ridges (29), to provide a series of at least 3 surface reflections of any light impinging thereon, before the light travels toward the viewer's eyes. The reflectivity at any one surface reflection is less than about 5% of normal inci-dent light, so less than about 0.05% (and preferably not more than 0.02%) of such incident light is returned toward the viewer after 3 reflections, and less after (4). A viewer thus can see the dye/pigment images clearly from any direction and free from no-ticeable reflected light from the outer surface, and without loss of detail or contrast in dark areas.

Title: Arrangement for detecting a gaseous substance
Inventor: SAUER RALF-ROLAND
IPC: H01S3/1055
Filed: 1995-01-24
Abstract: A gas laser 1 such as a 13CO2-laser emits at two different wavelengths (.lambda.1, .lambda.2) with a sine-shaped adjustment of a resonator mirror or a grating 13 such as a Littrow grating.  The gas laser emits radiation at the two desired wavelengths (.lambda.1, .lambda.2) in two mutually adjacent intervals of the resonator length L because of a suitable dimensioning of the grating 13 with respect to grating structure and angle position, the outcoupling factor of the outcoupling mirror 12, the resonator length L and the composition of the gas of the laser.  The laser emission is inhibited at the crossover between the two intervals and the sine-shaped modulation (for example with a piezo element) of the resonator length L is essentially symmetrical about this crossover.  The invention is also directed to an arrangement for detecting a substance such as NH3 in a flue gas.  This arrangement includes a two wavelengths laser light source 1, a modulation unit 14 and a reference detection unit D1; a transmission optic 2; a measuring path 3 which contains the substance to be detected; a receiving optic 4 and a measuring detector D2.  An evaluation apparatus 5 is also provided which determines the ratio of the light absorption in the measuring path 3 at the two wavelengths (.lambda.1, .lambda.2) and determines therefrom the concentration of the substance to be detected in the measuring path 3.

Title: Energy-efficient, finned-coil heat exchanger
Inventor: KALE HEMANT D
IPC: F28F1/14
Filed: 1995-04-07
Abstract: A finned-coil heat exchanger has a housing with spaced walls defining an internal chamber, heated fluid conducting tubes, a series of spaced fins in contact with the tubes to transfer heat to upwardly flowing air, the fins being horizontally spaced with the larger dimension of the fin surface extending vertically and the shorter dimension extending horizontally, and a fan unit adjacent the housing upper end to draw air therefrom, whereby air within the chamber rises naturally as a result of buoyancy due to its heat gain and the fan thereby uses less energy to draw air from the housing with the overall assembly being more compact and operating more quietly.  An air inlet is defined at the housing bottom or at the lower end of the front wall. The housing may have a chimney shape to enhance hot air movement or have an enclosure over the upper outlet. A series of such heat exchangers may be combined within a common housing with a common fan to increase overall capacity.
