Granted: 1992-08-20
Abstract: Two beams (14,16) extend between mounting pads (10,12) all pref. formed as a unitary body of piezoelectric material, e.g. quartz. An AC signal applied to electrodes (28,30) makes the beams vibrate towards and away from each other 180 deg. out of phase. The pads are pulled towards one another (longitudinal pumping) degrading accuracy. Pumping is reduced by maintaining the beam positions as straight as possible compensating for the effect of non-symmetrical boundary conditions. Pref. the beams are shaped to bow towards each other or away from each other; or masses are placed at lateral edge mid-points; or beam width varies; or the junctions with the pads are configured.

Title: Improvements in burners
Inventor: WARD TREVOR
IPC: F23L15/00
Filed: 1984-03-06
Granted: 1987-06-25
Abstract: The present invention relates to a burner which, in one mode can serve as a burner per se and in an alternate mode as a flue for removing waste gas from a combustion space.The burner has a body 1 which defines a passage 2forming in part a flow path for gases between two openings 3 and 4. The first opening serves either as inlet for receiving air for combustion with the fuel in a combustion chamber 16 in one mode of operation or as an outlet for discharging waste gas from the passage 2 in an alternate mode. The second opening 3 serves as an outlet for combustion products in the one mode of operation or as an inlet for receiving waste gas in the alternate mode. An assembly 5 injects fuel and air into the passage 2 and the fuel and air first mix in a nozzle 31 with the fuel being ignited by an electrode 47. The fuel is combusted in a pre-combustion chamber 32 before entering the main combustion chamber 16. The fuel is partially or fully pre-combusted irrespective of the mode in which the burner is operating to avoid prepurging with air or re-ignition between flue and firing cycles.

Title: Method and apparatus for thermal patterning of textile subtrates
Inventor: GREENWAY JOHN MICHAEL
IPC: D06C23/00
Filed: 1984-01-09
Granted: 1987-09-03
Abstract: The invention provides method and apparatus for imparting visual surface effects to a relatively moving, thermally modifiable substrate (12) by application of discrete streams of heated pressurised fluid, e.g. gas, to surface areas of the substrate. The apparatus includes an elongate manifold assembly (30) comprising two gas receiving compartments, (81, 160), each extending across the path of said substrate. Heated gas from the first compartment passes into the second compartment, which is comprised of a series of chambers (162, 166) with an elongate exit slot (115) positioned closely adjacent the substrate surface. The gas is uniformly mixed within the second compartment, and may then be directed from the exit slot onto the substrate as a thin, continuous stream or curtain extending the length of the manifold. By use of blocking streams of relatively cool gas which deflect the dilute selected lateral segments of the heated gas stream in accordance with pattern information after the curtain of heated gas emerges from the exit slot, smaller streams of groups of streams may be formed which squarely impinge on the substrate surface and impart a selected pattern to the substrate, by thermal modification of the surface.
