Publication number: 20160281722Abstract: A supersonic compressor including a rotor to deliver a gas at supersonic conditions to a diffuser. The diffuser includes a plurality of aerodynamic ducts that have converging and diverging portions, for deceleration of gas to subsonic conditions and then for expansion of subsonic gas, to change kinetic energy of the gas to static pressure. The aerodynamic ducts include vortex generating structures for controlling boundary layer, and structures for changing the effective contraction ratio to enable starting even when the aerodynamic ducts are designed for high pressure ratios, and structures for boundary layer control. In an embodiment, aerodynamic ducts are provided having an aspect ratio of in excess of two to one, when viewed in cross-section orthogonal to flow direction at an entrance to the aerodynamic duct.Type: ApplicationFiled: April 14, 2016Publication date: September 29, 2016Inventors: William Byron Roberts, II, Shawn P.

Patent number: 9279334Abstract: A gas turbine engine with a compressor rotor having compressor impulse blades that delivers gas at supersonic conditions to a stator. The stator includes a one or more aerodynamic ducts that each have a converging portion and a diverging portion for deceleration of the selected gas to subsonic conditions and to deliver a high pressure oxidant containing gas to flameholders. The flameholders may be provided as trapped vortex combustors, for combustion of a fuel to produce hot pressurized combustion gases. The hot pressurized combustion gases are choked before passing out of an aerodynamic duct to a turbine. Work is recovered in a turbine by expanding the combustion gases through impulse blades. By balancing the axial loading on compressor impulse blades and turbine impulse blades, asymmetrical thrust is minimized or avoided.Type: GrantFiled: July 6, 2012Date of Patent: March 8, 2016Assignee: Dresser-Rand CompanyInventors: Shawn P.

Patent number: 6728979Abstract: A device for transferring medical patients from one table, bed, or gurney to another is disclosed. The device includes a slide board which is slid beneath the patient while the patient is on the gurney. The slide board is then connected to a winch which rests on a cart and can be activated in a controlled manner. The action of the winch pulling the slide board in a horizontal fashion makes the transfer of the patient simple and easy. The cart is designed to be mobile, but includes hooks for fixing the cart to the floor so that it may withstand the stress induced by the retraction of the winch cable.Type: GrantFiled: October 22, 2002Date of Patent: May 4, 2004Inventor: Byron Robert

Patent number: 6522436Abstract: In an optical communication system, a train of optical pulses is transmitted such that each pulse carries a set of multiplexed channels. In a receiver, the error rate for each channel is monitored and a subset of channels having the most favorable rate is selected to carry a first data stream. The remaining channels carry a second data stream. Error rate performance is determined on the basis of error detecting codes carried by the channels in the first and second data streams.Type: GrantFiled: July 9, 2001Date of Patent: February 18, 2003Assignee: Nortel Networks LimitedInventors: Kim Byron Roberts, Maurice M O'Sullivan, Alan Robinson, Richard Edward Epworth

Patent number: 6509990Abstract: Optical timing detection, for phase comparison of optical signals, or clock recovery is achieved by arranging an interferometer to be responsible to data transitions. A pulse train is fed into both arms of the interferometer. An optical amplifier (20) enables the interference condition to be changed when the data is fed into one arm. The output changed if the data transitions lose synchronisation with the pulse train.Type: GrantFiled: July 31, 2000Date of Patent: January 21, 2003Assignee: Nortel Networks LimitedInventor: Kim Byron Roberts

Patent number: 6486990Abstract: A sub-harmonic clock signal is provided in a series of soliton optical pulses that are transmitted at a given line rate in a soliton optical transmission system. The line rate defines time slots of equal duration. Each soliton optical pulse in every N time slots is modulated in a manner to make the pulse distinguishable from pulses in other time slots. The frequency of the sub-harmonic clock signal is equal to the line rate divided by N. This technique of providing a clock signal allows simple recovery of the clock signal using a PIN diode photo detector and a bandpass filter of appropriate bandwidth.Type: GrantFiled: December 18, 1998Date of Patent: November 26, 2002Assignee: Nortel Networks LimitedInventors: Kim Byron Roberts, Hanan Anis, Maurice S.

Patent number: 6483617Abstract: An optical transmission system comprises a number of optical terminals connected by optical waveguides such as optical fibers. Nonlinear processes occurring within an optical transmission medium of the waveguide or within the optical terminals is detected by a monitor which outputs monitored data representative of the products of nonlinearity. The data is used to control the power of the optical signal such that power is regulated to avoid the onset of the nonlinear process. The data may also be used to indicate an alarm condition to an operator. A monitor for four wave mixing detection utilizes dither signals applied to respective frequency components of a wavelength division multiplexed signal, products of the four wave mixing process being detected in the monitor by correlation between a sample of a received optical signal and reference data representative of dither induced modulation in the four wave mixing product.Type: GrantFiled: August 11, 2000Date of Patent: November 19, 2002Assignee: Nortel Networks LimitedInventor: Kim Byron Roberts
