Patent number: 11939870Abstract: A gas-cycle system operable using a Bell-Coleman cycle, the gas-cycle system comprising an expander (23) and a compressor (27) incorporated in a flow path (13). The expander (23) and compressor (27) are integrated in a rotary machine (41), and each comprises a rotor assembly (70) configured to define one or more zones (80) each of which changes continuously in volume during a rotation cycle of the rotor assembly. The expander (23) and compressor (27) are drivingly interconnected whereby rotational drive applied to one is transmitted directly to the other. Each rotor assembly (70) comprises an inner rotor (73) and an outer rotor (75) adapted to rotate about parallel axes at different rotational speeds. The inner rotors (73) are each drivingly connected to a common shaft for rotation therewith. The two outer rotors (75) are coupled together such that rotational drive applied to one is transmitted directly to the other.Type: GrantFiled: August 10, 2020Date of Patent: March 26, 2024Inventor: Eric Davies

Patent number: 6065356Abstract: Determining a characteristic or characteristics of a particular material such as the type, constitution, surface characteristics, or general flowability of the material. The material flows through a measuring cell (1) of constant volume so as to maintain a substantially constant volume of flowing material in the measuring cell. The weight of material in the measuring cell is continuously monitored and oscillations in the weight of the contents of the measuring cell as the material flows through the measuring cell are compared with stored comparative information to determine the material.Type: GrantFiled: May 26, 1999Date of Patent: May 23, 2000Assignee: Industrial Research LimitedInventor: Clive Eric Davies

Patent number: 5654984Abstract: A method and apparatus for communicating a modulated signal across an isolation barrier using capacitors is provided. The present invention allows low distortion communication of an audio signal across an isolation barrier without the need for a large and bulky isolation transformer. The present invention may be used to provide telephone line isolation for modem applications compliant with governmental regulations. A line interface integrated circuit (IC) may be connected directly to a telephone line and powered by the telephone line. The line interface IC may include a sigma delta modulator to communicate the receive signal across a capacitor over an isolation barrier and a digital-to-analog (D/A) converter to provide an analog transmit signal from a sigma delta bit stream communicated across a capacitor over an isolation barrier. Circuitry on the opposite side of the isolation barrier includes similar components to process the transmit and receive signals.Type: GrantFiled: December 3, 1993Date of Patent: August 5, 1997Assignee: Silicon Systems, Inc.Inventors: Russell A.

Patent number: 5564061Abstract: The present invention provides a configurable architecture for serial communications. The architecture can emulate parallel to serial conversion devices for both synchronous and asynchronous data transmission. The invention uses a plurality of register sets to emulate standard interfaces. One register block performs data and control storage to communicate between a host computer and a local processor. A second register block emulates a serial communications controller (SCC) with its own data control storage and features to implement a number of communication protocols. The SCC provides serial data output. This invention provides an architecture of flexibility optimizing a configuration for synchronous and asynchronous requirements using the same basic blocks while still maintaining an interface compatible with standard requirements.Type: GrantFiled: February 25, 1994Date of Patent: October 8, 1996Assignee: Silicon Systems, Inc.Inventors: Eric Davies, Daun Langston

Patent number: 5561826Abstract: A device for coupling a host computer to a serial communications device. A dual port register set is coupled to the CPU bus of a host computer. The dual port registers receive the control signals and data from the host computer. This information is immediately available to be read by a serial communications controller. In this invention, one channel of a two-channel serial communications controller is implemented to receive the parallel data and convert it to serial output. The parallel data is also provided directly to a microprocessor interface for use by a local microprocessor, if desired. The present invention eliminates unneeded conversion steps and reduces the amount of circuitry required to implement serial communications functions.Type: GrantFiled: September 11, 1995Date of Patent: October 1, 1996Assignee: Silicon Systems, Inc.Inventors: Eric Davies, Daun Langston

Patent number: 5018226Abstract: A transport unit particularly adapted to contain an injured person in a manner that the person can be moved with relative comfort and safety. There is a rigid containing structure having inflatable cushions positioned therein and arranged to fit the contours of a person's body. The person is placed in the container, and a lid of the container is placed over the person, with the cushions then being inflated to firmly, yet gently, hold the person in place.Type: GrantFiled: August 19, 1988Date of Patent: May 28, 1991Assignee: William Price WilliamsInventors: Eric Davies, deceased, Ian R.

Patent number: 4060806Abstract: A phased array radar having a plurality of antennae, each connected with a respective receiving channel, is provided with apparatus to suppress variations in phase and gain in the receiving channels. The apparatus injects a reference signal into a normally provided head amplifier in each channel, which then passes through the same amplification and frequency changing circuits as the signal induced in each antennae. Thus the differential phase shifts of the reference signal and the radar carrier frequency are substantially constant. The gains of the head amplifiers are controlled by the action of an AGC loop.Type: GrantFiled: May 14, 1976Date of Patent: November 29, 1977Assignee: The Marconi Company LimitedInventors: Eric Davies, deceased, by Douglas Philip Marr, co-executor
