Title: Dual function reflector structures for interdigital saw transducers.
Inventor: GAU JOHN
IPC: H03H9/02
Filed: 1993-05-13
Abstract: An SAW reflector (302) structure located between multiple interdigitated generator/receivers located on a piezoelectric substrate (100) forming a ladder type SAW device is described. The reflector structure reduces both reflections due to mechanical-electrical loading from the physical presence of generator/receiver fingers without using a split finger arrangement as well as reflections due to the regenerated reflection from the generator/receiver. The reflector has a first acoustic phase center. The generator/receiver has a second acoustic phase center, a regenerated voltage coefficient of reflection r?e? and a mechanical-electrical loading coefficient of reflection r?m?. The reflector is used for simultaneously reflecting both regenerated and mechanical-electrical loading induced reflections from the generator/receiver. The reflector is sized for a strength of reflection equal to the square root of the sum of the regenerated and mechanical-electrical loading reflections squared. The reflector's phase center is positioned an integral number of acoustic wavelengths from the phase center of the generator/receiver plus (or minus) a distance equivalent to a phase angle given by 90 degrees plus the inverse tangent of the ratio of the mechanical-electrical loading reflection to the regenerated reflection times a wavelength dependent proportionality factor.

Title: Heating apparatus.
Inventor: HART JOHN GRAHAM
IPC: F24H1/14
Filed: 1993-08-13
Abstract: A method of heating a liquid which comprises providing a mandrel (12) within a heating element (14) having at least one surface, and passing the liquid down the mandrel in the form of a thin film (22) in such a manner that it does not contact the heating surface (14). This may be carried out in apparatus which comprises a heating element (14) within which is located a mandrel (12), not in contact with the element, a source of liquid (18), and means (20) for allowing the liquid from the source to flow over the mandrel (12) in the form of a thin film (22). The mandrel (12) will normally be maintained in a vertical orientation and the source of liquid (18) may be at the top thereof. The liquid is allowed to run as a film (22) down the surface of the mandrel (12). The mandrel (12) is surrounded by the hot surface of the heating element (14) and heat passes principally by radiant heat across the gap (16) between the hot surface of the heating element (14) to the liquid passing down the mandrel (12). Thus there is no direct contact between the liquid to be heated and any heated surface of the heating element (14). The mandrel (12) itself will normally not be heated and, indeed, it may be made from materials having good corrosion and release properties but a thermal conductivity so poor that they would not normally be used in heat exchanger manufacture. It need not be made from metal, and may, for example, be made from materials such as ceramics or glass, optionally with release coatings of, for instance, PTFE.

Abstract: In order to produce a polycrystalline, single-phase linking semiconductor layer made of chalkopyrite type ABC2, a laminated structure comprising several layers is precipitated onto a substrate. The sandwich structure contains components in elemental form, as interelemental compound or as alloy, with a stoichiometric excess of component C. In a rapid annealing process at a heating rate of at least 10 °C per second up to a process temperature of at least 350 °C, the laminated structure is converted already after a few seconds into the linking semiconductor ABC2. By encapsulating the laminated structure, gas exchange is limited, preventing the most volatile components from evaporating. High-efficiency solar cells can be produced with this semiconductor.

Abstract: A transfer sheet for printing a substrate comprises a base film (1), a detachable release layer (2) arranged thereunder, a varnish layer (3) of a transluscent structure, a preferably vapour-deposited metal layer (4) arranged thereunder and also an external layer facing away from the base film (1). The external layer serves for bonding the decorative layer (3, 4), composed of the varnish layer (3) and the metal layer (4), to the substrate to be printed. To provide a sheet for printing a substrate which is easier to process than known embossing foils, it is proposed to form the external layer as a sealant (5) which does not have any adhesiveness of its own. Only in combination with an adhesive, which itself is not a component part of the transfer sheet, does the sealant (5) cause the transfer sheet to be bonded to the substrate to be printed.

IPC: C10J3/46

Abstract: An improved coal gasification process employing fluid bed reactors is disclosed. In the improved process, sulfur absorption on limestone is balanced between gasification and spent solids combustion stages. Part of the sulfur is absorbed during gasification with an  in situ  alkaline sorbent to form a fuel gas. The raw fuel gas is fed to a metallic sorbent desulfurization reactor to remove residual sulfur. The spent metallic sorbent is regenerated with air, steam or a combination thereof, forming a regeneration offgas containing sulfur. The offgas is recycled to the combustion stage where the sulfur is absorbed on the alkaline sorbent from the gasifier. Substantially complete oxidation of sulfides in the limestone sorbent to sulfates can thus be promoted in the combustion stage to substantially eliminate sulfides from process waste solids.

Abstract: A catching device 3 for a carriage 1, guided on rails 2, of an inclined or vertical lift engages on each rail 2 in a clamping manner without sliding friction. It consists in each case of an eccentric 31, held on a stop and preloaded in its direction of action, and of a brake block 32 as engagement safety feature. The carriage 1 has a main frame 11, on which the car is mounted, and a sliding frame 12 which is guided in a sliding manner in the direction of travel relative to the main frame 11. To dampen the relative movement upon engagement of the catching device 3, at least one shock absorber 6 is arranged between main frame 11 and sliding frame 12. In case of an emergency, a slack-rope tripping mechanism 4 and a speed limiter 5 are provided as tripping devices, which throw the catching device 3 into engagement with the rails 2 and immediately clamp the sliding frame 12 on them by means of self-locking friction. The main frame 11 with the car runs onto the sliding frame 12 and is gradually brought to a stop via the shock absorber 6. The brake path of the carriage 1 can here be dimensioned in a manner suitable for all conceivable applications and is independent of the instantaneous coefficient of friction on the rails 2 on account of the self-locking engagement of the catching and clamping device 3. <IMAGE>

Abstract: A method for cleaning hot gas and optionally recovering energy therefrom. The gas is cooled in a first stage by saturating the gas with water and finely-divided cooling water is delivered to the gas in a second stage so as to cool the gas to a temperature of 5-20  DEG C, whereupon vapour present in the gas condenses and entrains therewith contaminants contained in the gas. The cooled gas is then led away and the heated water is cooled by heat exchange with a medium which may then be used for heating purposes, wherein after being cooled the water is returned to the first and/or the second stage as cooling water. An arrangement for carrying out the method includes an inlet passage (1), means (2) mounted in the passageway for delivering cooling water in a finely-divided state, a cooling chamber (4) which includes means (5) for delivering cooling water in a finely-divided state, a contaminant treatment container (12), an overflow (14), a pump (18), a heat exchanger (20), conduits (16, 17, 19, 22, 23, 24) and a gas outlet passage (9).
