An insulation body is attached to the framework 2 and a plurality of brackets 5 are used to interconnect the framework 2 and the facade elements 1. The fixings 6 are used to mount the brackets 5 to the support framework 2. In-line brackets 5 are interconnected by a linear support element 7. Loading L is applied downwardly on the brackets 5 due to gravity. The load is transmitted to a screw 11 which acts in a shear direction S. Rotational moments M₁, M₂ are resisted by the bracket connection element 7.

A thermoacoustic engine-generator that converts waste heat into electrical power. Thermal energy is converted to useful work via temperature-pressure amplification of periodic acoustic traveling waves in a compressible working fluid which cause the armature of a linear alternator to reciprocate and produce alternating current electrical energy. An external oscillator initiates reciprocating motion in the armature of a linear alternator. The armature is a combination fluid pump and fluid motor as well as the induction armature of a linear alternator. The pump end of the armature generates an acoustic traveling wave with each cycle of the armature. The traveling wave enters a waveguide-heat exchanger and is amplified in temperature, pressure and propagation velocity by thermal conduction of energy through the wall of the waveguide. The amplified traveling wave acts upon the opposite end of the armature, causing it to reciprocate within the magnetic field windings of the generator, and generate an electrical current as well as a new acoustic traveling wave. When the operating temperature gradient is attained across the hot and cold heat exchangers, the thermoacoustic engine-generator becomes acoustically resonant and self-regenerative, and will continue to operate as long as the thermal gradient is maintained. The theoretical conversion efficiency is dependent on the thermal gradient, and is 63% of Carnot.

A prefabricated, modular enclosure comprising a plurality of plastic foam EPS components forming an integrated structure characterized by energy efficiency and ease of assembly. Wall panels, window panels, door panels, gable panels and roofing panels may be custom configured and glued together, utilizing adaptors on their sides and corner assemblies at intersections. The panels include major and minor channel struts that longitudinally penetrate the panel bodies, snugly lodging within receptive slots. The struts do not contact each other, and no portions of the struts traverses the panel thickness from inside to outside, thus minimizing thermal loss pathways. The wider, major reinforcement struts have offset portions spaced from interior panel surfaces that project interiorly of the enclosure and form a rigid mounting for interior finishing. The chase defined between the modular panels and the interior wall finishing, afforded by the offset struts, may house plumbing, wiring or the like.

For heat conditioning flat panel glass substrates the substrates are directly exposed in vacuum to the radiation of lamps, the lamps being selected so that their spectral radiation characteristics (b, c) fit with the absorption characteristics (a) of the glass of the substrate.

A container system allows a user to register a bulk product unit at a predetermined elevation by engaging a stop disposed at a deepest point of an engagement slot. The engagement slot is disposed in a wall of a container containing a chamber having an inlet for receiving a product vessel. The neck of the product unit may be lowered into the slot, thereby moving the product vessel through the inlet of the chamber, and positioning the dispensing valve outside of the container. The first embodiment further comprises a retrofit system for adapting an existing product cooler to contain a saddle to support the neck of a bulk product unit. In a second embodiment, the container system is designed to receive and dispense gravity fed flexible packages, such as bulk wine. In a third embodiment, the container system comprises a product unit that is refillable, sealable, and separable for cleansing.

The system can be used to provide non-contact heating and cooling of a test sample by use of an inert fluid. Accurate temperature control can be maintained, e.g., by use of controllers to provide temperature feedback control.

A relay and a process for producing a relay are described, three contact pins being provided for the relay. The three contact pins are preferably manufactured from a punching and are fixed together as a contact punching with respect to a yoke of the magnetic coil through insertion into a base. As a result of the use of a contact punching with the three contact pins connected rigidly to one another, adjustment and handling of the three contact pins during production of the relay is relatively simple.

The heating pipe comprises a water cavity, heating films for water heating are arranged on the outer sides of two side walls of the water cavityto form double-side water heating. The water heater is simple in structure, cold water is clamped between the two heating films to be subjected to double-side heating, heat can be effectively surrounded, heat loss is minimized, cold water heating area is increased, and the heating pipe is more even in heating. Due to the fact that heating area is increased, water scale is not easily produced in the heating pipe, and the water heater is more environment-friendly.
