Title: Sliding doors or windows
Inventor: HIBBERT ERIC
IPC: E06B7/06
Filed: 1981-11-21
Abstract: In a sliding door or window, the head section 1 of the fixed frame has an outside wall 2 and an inside wall 3 and a transverse wall 4 extends spaced above the top of a fixed panel 14 between the walls 2 and 3. The head section is divided into two longitudinal compartments by a partition 7. The inner compartment forms a duct 12 opening to atmosphere through aperture(s) 19 in the wall 4 and opening to the interior of the building through vent opening(s) 23 in the inside wall 3. An obturator e.g. a control flap 24 mounted for pivotal movement is associated with the opening 23. The gap "a" between the fixed panel 14 and the transverse wall 4 provides an air path. <IMAGE>

Patent GB-2094464-A (GB)
Title: Gas turbine combustor
IPC: F23R3/16
Filed: 1982-02-12
Abstract: A combustor (10) is capable of reducing the noxious emissions such as fuel bound and thermal nitrogen oxide products during combustion of high nitrogen bearing and high aromatic content fuels. It includes a plurality of substantially concentric pipes (11 to 16) defining annular passages (12a to 16a) with annular venturi shaped divergent nozzles (20 to 24) to facilitate fast mixing of axially supplied air between adjacent annular passages. The longitudinal spacing between at least two adjacent nozzles defines first and second divergent cavities (30, 40). A fuel rich toroidal vortex (T) is formed in proximity to a central fuel jet in the first cavity (30) and advantageously converts fuel bound nitrogen to N2. A fuel lean toroidal vortex (T') formed in the second cavity (40) mixes hot combustion products with additional gaseous reactant to complete the combustion while avoiding locally high temperatures, and thus thermal NOx formation. A ring of jet nozzles (42) radially injects relatively small amounts of high pressure gaseous reactant or steam to form a throat to separate and stabilize the vortices. Alternatively, the pipes extending between the two cavities can include a convergent and divergent portion forming the throat. <IMAGE>

Patent GB-2139715-A (GB)
Title: Variable transmission system
Inventor: GOSS PETER HAROLD
IPC: F16H49/00
Filed: 1983-05-14
Abstract: A transmission system having a steplessly variable transmission ratio comprises a rotary annulus member (2) with teeth (4a) on its radially inward surface. In meshing engagement with the teeth (4a) is at least one drive wheel (5) connected to a drive input or output member (6, 16). The member (2) is connected to a shaft (1) for the output or input of drive. Disposed around the member (2) is a ring member (9) which can be driven in rotation and which has a radially inward surface with at least one depression therein. Mounted in the member (2) and slidable in respective radial directions are pin members (13) which can be urged radially inwardly by the inward surface of the ring member (9) so as to impede meshing engagement between the drive wheel (5) and the teeth (4a). When the drive wheel (5) is aligned with the depression (12), the pin members (13) can be displaced outwardly so as not to impede such meshing engagement. The ring member (9), when rotated at a faster or slower speed than the member (2), thereby controls the meshing engagement of the drive wheel (5) and the teeth (4a), thus producing a selectively variably controlled planetary motion between the drive wheel (5) and the annulus member (2). <IMAGE>
