Title: Turbine combustion chamber
Inventor: DEPIETRO SIMON MARIO
IPC: F23R3/34
Filed: 1994-09-02
Abstract: A combustion chamber for a gas or liquid fuelled turbine, has a central fuel injector module (13) surrounded by other fuel injector modules (5) and projecting downstream of them and their associated flame zone (2). The central module (13) comprises a radial jet fuel nozzle (18) the radial jets passing into an axial flow air chamber (16) where it is diverted to a secondary flame zone (14) downstream of the central module. The central nozzle (18) and chamber (16) are contained by tubes (27 and 37) which between them form an annular duct (10) which is fed with air and controllable fuel to feed in turn the secondary zone (14). This dispersed feeding of the secondary zone (14) is desirable during the transition from primary zone operation to secondary zone operation with increase in load. The fuel can be distributed to the injector modules so that (a) 100% passes to the outer modules, (b) a major portion passes to the outer modules with all modules individually ignited and (c) a major portion passes to the outer modules with a single flame zone fed by all the modules but centered on and downstream of the central module. The transition between conditions (b) and (c) is achieved by feeding 100% fuel to the central module to extinguish the outer modules and then reducing the proportion to the central module while increasing the proportions of the outer modules without igniting them individually. <IMAGE>

IPC: C07C69/747
Filed: 1995-10-20
Abstract: A lower alkyl ester of 3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropane carboxylic acid, which is an intermediate for insecticides, is prepared by treating a lower alkyl ester of 6-bromo-6-chloro-3,3-dimethyl-7,7,7- trifluorohept-4-enoic acid or 6,6-dichloro-3,3-dimethyl-7,7,7-trifluorohept-4-enoic acid with an alkali metal lower alkoxylate in the presence of an aromatic hydrocarbon solvent under conditions under which the lower alcohol of the alkoxylate is removed from the reaction mixture by distillation with the aromatic solvent. This avoids using a polar aprotic base, which has disadvantages because the work-up procedure leads to difficulties in recovering the solvent in a reusable form.

Title: Method and apparatus for forming a bottom-profiled cup
Inventor: BULSO JR JOSEPH D
IPC: B21D22/24
Filed: 1997-04-03
Abstract: An apparatus and method for forming a cup (10) having a profiled bottom generally includes a draw die (20) disposed at a first level of a double acting press. The draw die (20) cooperates with a draw pad (22) and a cut edge (24) to form and hold a blank (28) formed from a sheet of material (M). A punch assembly (30) is configured to travel through the draw die (20), thereby drawing the blank (28) over the draw die (20) into a cup (60). The punch assembly (30) transports the cup (60) to a second level of the press where it bottoms out on a die core (50) and a ring pad (51). One element of the punch assembly (30) continues to move beyond the second level of the press, thereby drawing a portion of the cup (60) over the die core (50) and profiling the bottom of the cup (60). The profiled cup (10) is then returned to the second level of the press where it is removed from the punch assembly (30) and transferred. The bottom profile insures that the cup will retain its shape during the transfer operation.

Title: Alarm reporting system
Inventor: MILLER PAUL DAVID
IPC: G08B29/18
Filed: 1997-10-18
Abstract: A controlling interface unit (3) can link a plurality of event sensors (1) associated with premises, via wired communication lines (4, 7; 6, 10) or radio transmissions (5, 8; 9, 13), to a remote alarm receiving centre (11) and a remote auxiliary facility (14) for filtering out potential false alarms from those premises. The interface unit (3) is capable of routing signals originating from a selected type of sensor (1) to the auxiliary filtering facility (14) instead of or in addition to transmitting the same signals to the alarm receiving centre (11). Depending on the circumstances feedback signals may then be transmitted from the auxiliary filtering facility (14) to the controlling interface unit (3) to negate an alarm condition. A memory unit (15) may store data from the event sensors (1) for a limited time period, to assist the auxiliary filtering facility (14) in determination of whether the alarm is valid.
Patent GB-2315129-A (GB)
Title: Integrated optical modulators
Inventor: O'DONNELL ADRIAN CHARLES
IPC: G02F1/225
Filed: 1996-05-17
Abstract: An integrated optical modulator of the Mach-Zehnder type has a waveguide which, for part of its length, is divided into two waveguide sections (11, 12) arranged logically in parallel. Incoming light is divided to pass along the two sections (11, 12) and is then recombined before leaving the modulator. Each waveguide section has a pair of electrodes (13, 14) and (14, 15) associated therewith to generate an electric field through which the respective waveguide section passes, though there may be a single electrode (14) between the two waveguide sections (11, 12) to serve as one electrode of each pair, with the other electrode of each pair commoned. The physical arrangement of one waveguide section (11) and its associated electrodes (13, 14) is different from that of the other waveguide section (12) and its associated electrodes (14, 15), such that the electric fields to which light propagated along the two waveguide sections (11, 12) are respectively subjected are different when a single driving voltage is applied to the electrodes (13, 14, 15) associated with the waveguide sections. In an alternative arrangement there is provided an amplitude modulator (30) followed by a phase modulator (31).

The contents of the envelope can be removed by folding the innermost flap portion 9C of the envelope outwards. To re-use the envelope, the document to be sent is inserted by means of the open side flap portion 9C. A second adhesive region 15 of the side flap portion 9C is then activated and the side flap portion 9C is folded back onto the rear face 3 of the envelope.
