Publication number: 20220088421Abstract: An air purifying breathing system for providing filtered air to a user. The air purifying breathing system comprises a headgear that is not self-contained and is open under a face shield to let air flow out of the headgear. A fan component moves ambient air into the system and across a filtering component. The filtering component comprises a first and second filter, each filter using different filter media. After the air is filtered, it exits the filtering component and into the headgear at the top for distribution to the user. The filtered air flows past the user and out the opening under the face shield. The slight positive pressure from the airflow prevents the inflow of unfiltered air into the headgear. The filtering component may be attached to or integrated into the headgear or may be retained by a vest or harness.Type: ApplicationFiled: January 12, 2021Publication date: March 24, 2022Inventor: John H. Moore

Patent number: 5654037Abstract: A process for painting a fiber reinforced composite plastic member. Prolonged pre-heating of the composite member is used to minimize defects in a subsequently applied clear resin finish coating. The finish coating is applied and curing of it commenced before the composite member has substantially cooled, effective to inhibit formation of pits and blisters in the clear finish coating, and delamination in pore areas beneath said clear finish coating.Type: GrantFiled: March 24, 1995Date of Patent: August 5, 1997Assignee: APX InternationalInventors: John H. Moore, Mark J. Marentic

Patent number: 5600255Abstract: A method and apparatus for measuring the electrical resistance of a circuit energized with AC power. The invention imposes a known DC current in the circuit under test and senses a resulting DC voltage drop that corresponds to the resistance of the circuit. The invention senses AC overvoltage conditions in the circuit under test and electrically isolates the measuring circuit from the circuit under test.Type: GrantFiled: November 20, 1995Date of Patent: February 4, 1997Assignee: Electro-Test, Inc.Inventors: John H. Moore, Christopher J. Revak

Patent number: 4774834Abstract: An engine sensor includes a radiation response element which in use is coupled by a radiation transmission path with a combustion chamber of an internal combustion engine so that a signal is provided when combustion occurs in the combustion chamber. The radiation transmitting path is incorporated into a component such as an engine starting aid which is mounted in a bore in the cylinder head of the engine. In the sample a quartz rod is locating in a tubular member about which is wound an electric heating element. The quartz rod can transmit light through a powdered glass filling to a through quartz rod at the end of which is mounted the sensing element.Type: GrantFiled: September 17, 1987Date of Patent: October 4, 1988Assignee: Lucas Industries Public Limited CompanyInventors: Michael F. Russell, Russell A. Bruce, John H. Moore

Patent number: 4523563Abstract: An electronic control system for a fuel pump of an internal combustion engine includes a power circuit which controls the flow of electric current in an electromagnetic device coupled to a spill valve of the fuel pump. Power is supplied to the power circuit through a resistor through which power is also supplied to an engine speed sensing circuit. The system also includes a control unit which supplies control signals to the power circuit to effect closure of the valve and hence delivery of fuel, in timed relationship with the engine. The control unit receives the speed signal from the speed sensing circuit and also senses the voltage applied thereto. In addition it receives a demand signal from a transducer and controls current flow in a relay winding having contacts in parallel with the resistor.Type: GrantFiled: April 6, 1984Date of Patent: June 18, 1985Assignee: Lucas Industries public limited companyInventors: John H. Moore, Ian J. Harvey

Patent number: 4487181Abstract: A fuel supply system for an internal combustion engine includes a mechanically actuated fuel pump which has at least one electromagnetically operable valve for controlling an operating parameter of the pump e.g. fuel delivery. A transducer is provided which provides an indication of the position of a moving part of the pump which determines the fuel delivery. The system also includes an electronic control system which determines the current flow to the valve and hence the position of said part. When the pump is manufactured there is created during its testing test data which is stored in a memory which conveniently is secured to the pump. The test data in the memory is utilized by the control system during normal operation of the fuel supply system.Type: GrantFiled: March 14, 1983Date of Patent: December 11, 1984Assignee: Lucas Industries public limited companyInventors: John H. Moore, Andrew P. Ives

Patent number: 4466439Abstract: The specification discloses a device for inducing dive reflex, and the associated bradycardia and vasoconstriction in the human through the application of cold stimulus to the facial nerve, which communicates with the parasympathetic nervous system. The device comprises a pair of opposed temperature-controllable, face-engaging members and a tension member interconnecting and biasing the face-engaging members toward one another to secure the face-engaging members on the face over a portion of the area in which the facial nerve surfaces. A method of inducing dive reflex using the device is also disclosed.Type: GrantFiled: February 8, 1982Date of Patent: August 21, 1984Inventor: John H. Moore

Patent number: 4453124Abstract: A linear inductive transducer includes a non-magnetic former which has a bore in which is slidable a core formed from magnetic material. The core in use is moved axially within the former by the component whose axial position it is required to sense. The former has three circumferential grooves in which are located coils connected together to form the transducer winding the inductance of which varies with the axial position of the core. The widths of the coils and the number of turns in each coil varies so as to produce a substantially linear variation of inductance as the core is moved. A temperature responsive resistor is mounted in close proximity to the winding and is connected in a resistance network which includes the winding. The inductance of the winding is checked by applying a step voltage to the resistance network and monitoring the change of current in a part of the network.Type: GrantFiled: July 6, 1982Date of Patent: June 5, 1984Assignee: Lucas Industries plcInventors: John H. Francis, John P. Vernon, John H. Moore

Patent number: 4257944Abstract: Process for disperse azo dyes having a cyano radical ortho to the azo group by reacting the corresponding halogeno dye with a covalent non-metallic nitrile in the presence of a copper catalyst and an acid acceptor. Previous processes have used a metal cyanide as the cyanide source. The present process does, however, contemplate the use of a non-metallic nitrile, even in small amounts, in combination with a metal cyanide for which advantages are to be gained in terms of reduced copper usage. The non-metallic nitrile is preferably a cyanohydrin which may be prepared in situ by reacting an aldehyde or ketone with a metal cyanide. The metal cyanide may itself provide the copper catalyst.Type: GrantFiled: March 26, 1979Date of Patent: March 24, 1981Assignee: Imperial Chemical Industries LimitedInventors: Peter M. Quan, James S. Hunter, John R. Lawson, John H. Moore

Patent number: 4146001Abstract: An angular position signal generator includes a rotor and a stator each having an arrangement of salient magnetic poles. The poles on the rotor are all of the same polarity and are spaced at unequal angles around the axis of the rotor. The poles on the stator are identically arranged so that in at least one position of the rotor all the poles are aligned and in at least two other positions only some of the poles are aligned. As the rotor rotates, therefore, the flux flowing between the poles fluctuates and a winding in the flux path produces pulses of different magnitudes at these various positions of the rotor.Type: GrantFiled: January 20, 1978Date of Patent: March 27, 1979Assignee: The Lucas Electrical Company LimitedInventors: Paul M. McCarthy, Duncan B. Hodgson, Andrew P. Ives, John H. Moore
