Title: Swing doors.
Inventor: MAIDMENT ROBERT AINSLIE MORISO
IPC: E05D15/54
Filed: 1991-03-14
Abstract: In a door and door frame construction the door is hinged to the frame by one or more hinged structures, each hinged structure has a convex-surfaced support associated with the door and a convex-surfaced support associated with the door frame and at least two resilient strip-like S-shaped hinge members passing partially round each support and together with the other member forming a letter x or figure 8 configuration as seen in a direction along the supports. The members are tensioned round the supports and towards the lower end of the construction each support is provided with a surface (14, 15) raised from the general surface of the support and in contact with the raised surface on the other support. The tension in the hinges serves to bias the door to a closed position since the raised surfaces open a gap between the supports. The raised surfaces also slightly lift the door so that it is also biased closed by its weight. <IMAGE>

Title: Polymerisation of cyclic ethers
Inventor: STEWART MALCOLM JOHN
IPC: C08G65/16
Filed: 1991-11-19
Abstract: This invention relates to the production of hydroxy-terminated polymers in the 2,000-20,000 MW range suitable for use as prepolymers in curing reactions with isocyanates to produce elastomers. The process involves the continuous addition over periods of 25-50 hours of an oxirane (monoepoxide) or a mixture of an oxirane and an oxetane to a reaction mixture, consisting of stoichiometric excesses of oxonium ion-forming catalyst such as BF3-etherate and a diol initiator dissolved in an inert solvent. Under these conditions, chain extension of the diol occurs and the formation of cyclic oligomers and other impurities is minimised. The mole ratio of the initiator to catalyst is maintained at above 10:1 to suppress the formation of cationic terminal species on the growing polymer chain.

Title: Optical clock recovery
Inventor: SHIELDS JAMES ALEXANDER
IPC: H04B10/43
Filed: 1992-09-09
Abstract: Optical clock recovery is performed on an optical signal (10) containing both data and clock information by applying it to a photodetector (11) and adding part of the resulting electrical signal to the bias of a self-pulsating laser diode (15) so as to force its pulsation frequency to the frequency and phase of the clock component of the optical signal. This opto-electronic system of clock recovery allows the full received optical power at the receiver to be detected and is effected without recourse to filtering in the electrical regime, thereby avoiding being bit-rate specific. Prior to transmitting, the NR7 data signal is coded using 5B6B coding or CMI coding. <IMAGE>

Patent GB-2264406-A (GB)
Title: Adaptive commutation delay circuit for brushless dc motors
Inventor: AUSTIN CHARLES C
IPC: H02P6/14
Filed: 1992-11-25
Abstract: The circuit adjusts the commutation delay as a function of the rotational speed of the motor to maximize motor torque and minimize power consumption. The circuit includes a back-EMF sensing input 119, an oscillator 101, a voltage holding and proportioning circuit 103, 103a; 104, 104a, one or more comparators 105-106a and, optionally, an external control circuit 102. The back-EMF sensing input controls the operation of the oscillator. The voltage holding and proportioning circuit processes the oscillator output and provides outputs which are compared by the comparators. The comparators produce commutation delay signals, and, optionally, other signals. The circuit also allows adjustment to compensate for non-ideal back-EMF-to-rotor-position correspondence or fixed time delays inherent in the commutation process. Unlike the prior art, the circuit avoids the need for complex circuitry or external components. The circuit may be implemented entirely within a single integrated circuit. Circuit details are described (Figs 2-4, 7 and 8). In an alternative embodiment (Figs 9 and 10) the voltage proportioning circuit (1402) is connected between the output of the oscillator 101 and inputs to the comparators 105-106a. In a further embodiment (Figs 11 and 12) the voltage proportioning circuit (1104) is connected between the output of the oscillator 101 and the input of the voltage holding circuit (1102). <IMAGE>

Patent GB-2283088-A (GB)
Title: Fuel injector
Inventor: MINA THEODORS ISHAQ
IPC: F23R3/36
Filed: 1994-10-12
Abstract: A fuel injector for a gas turbine conbustor, operates on gas and liquid fuels selectively. The injector has a central liquid fuel duct 23 and jets 25 an annular gas duct 1 and gas jets 3, and a outer annular combustion air duct 9. Operation on the liquid fuel tends to cause combustion products to be ingested into the gas orifices so impeding efficient gas combustion. The invention provides apertures 17 between the outer air duct and the intermediate gas duct whereby during operation on liquid fuel air bleeds into the gas duct and purges the gas orifices 3. As an added advantage in a transition from liquid fuel to gas, the gas pressure is increased to a point where the air bleed is reversed and gas bleeds into the air duct. The pre-mixed gas/air is then emitted from swirlers surrounding the ring of gas jets. More efficient gas combustion results. The arrangement prevents spillage, flashback and fouling of the gas orifices during secondary fuel operation. <IMAGE>
