Patent number: 9192951Abstract: An air spray gun is described which is operated by blowing air past a nozzle, the air drawing the spray liquid from the nozzle and imparting momentum to it. The air cap includes formations to bias air flow towards the air horns having patterning air directed to them. The central opening extends towards the air horns, either in the form of a square opening with the corners of the square closest to the horns, or in the form of a compound curved shaped providing pronounced curvature of the corners at the axes toward the horns. This significantly improves paint spray patterning and discourages paint deposition on the air horns.Type: GrantFiled: May 14, 2012Date of Patent: November 24, 2015Assignee: Wagner Spraytech (UK) LimitedInventor: Timothy George Hopper

Patent number: 8590810Abstract: An air spray gun for paint has a tubular body, having an integral screw thread receiving a threaded collar. This secures an air cap against the end of the tube. The air cap has four horns, formed with obliquely inwards directed bores, for patterning the spray, by impinging on it from opposite sides in a manner analogous to that for known air caps having two horns. Behind the air cap in the tube is an air distributor for distributing air to either or both of the pairs of air horns as required to patterning of the paint spray. Paint flow is controlled by a needle withdrawable from a paint nozzle for paint flow. The to needle is in two parts, a front interchangeable part and a rear part connected to the trigger.Type: GrantFiled: October 8, 2012Date of Patent: November 26, 2013Inventors: Sarah Jane Woodgate, Timothy George Hopper

Patent number: 7509701Abstract: What is disclosed is a lifting apparatus, in particular a ferry landing stage, comprising a platform that is capable of being taken into a predetermined lift position with the aid of a hydraulic cylinder or of a cable winch. A safety stop by which the platform may be supported independently of the drive mechanism is associated to the drive mechanism.Type: GrantFiled: July 4, 2002Date of Patent: March 31, 2009Assignee: Bosch Rexroth AGInventors: Erich Wirzberger, Stephen George Hopper

Publication number: 20060039666Abstract: An integrated optical waveguide (1) having an in-line light sensor (2) integrally formed therewith for tapping off a small proportion of the signal transmitted along the waveguide (1). A first part (1A) of the waveguide leads to a photodiode portion (2) and a second part (1B) of the waveguide leads away from the photodiode portion (2), the photodiode portion (2) comprising one or more regions (14) of light absorbing material within the waveguide (1) arranged to absorb a minor proportion of light transmitted along the waveguide (1) and thereby to generate free charge carriers within the waveguide (1). Deep band gap levels (21) are introduced into photodiode portion by ion implantation to enable it to absorb selected wavelengths. The free charge carriers are detected by a p-i-n diode formed across the waveguide (1). Wavelength selective reflectors (11, 12) may be provided either side of the photodiode portion (2) so light passes repeatedly through the photodiode portion (2).Type: ApplicationFiled: December 27, 2002Publication date: February 23, 2006Inventors: Andrew Knights, Adrian Vonsovici, Dominic Brady, Andrew House, George Hopper

Patent number: 5714523Abstract: Process for alcoholizing and hydrolysing a flexible polyurethane foam by bringing a flexible polyurethane foam in contact with an alcoholizing polyol, allowing the foam and the polyol to react in the presence of a catalyst which enhances alcoholysis and hydrolysis of the foam in an amount of 0.001 to 0.25 and preferably 0.001 to 0.08% by weight based on the weight of the foam, then allowing the mixture to separate in an upper phase and a lower phase and collecting these phases in separate containers, wherein the hydrolysis is conducted by adding water and allowing the mixture to react with the water after the foam has been combined with the polyol and before the mixture is allowed to separate.Type: GrantFiled: January 21, 1997Date of Patent: February 3, 1998Assignee: Imperial Chemical Industries PLCInventors: Julian Francis George Hopper, Patrick Margriet Gaston Goegebeur, Harry Kooren

Patent number: 5691389Abstract: Process for recycling flexible foams by glycolysis and extraction. The glycolysis is conducted by allowing the foam to react with low molecular weight polyols, then allowing the mixture to separate in two phases.Type: GrantFiled: November 27, 1996Date of Patent: November 25, 1997Assignee: Imperial Chemical Industries PLCInventors: Giovanni Parrinello, David Thorpe, Gabriel Verhelst, Julian Francis George Hopper, Mireille Berthine Albert De Witte

Patent number: 5460597Abstract: A stimulator for use in marital orgasmic and sexual therapy for performing a simulation of cunnilingus is provided. The stimulator has an elongated cylindrical housing, simulated lips, a simulated tongue and is battery powered. The tongue is caused to move in and out with respect to the simulated lips; up and down; and side to side. These motions are attainable independently of the others. Three motors, separate switches, and three sets of cooperating but independent linkage are provided to accomplish this motion arrangement. A finger operated plunger type dispenser integral to the housing dispenses lubricant, medication, or other fluid onto the simulated tongue.Type: GrantFiled: August 11, 1994Date of Patent: October 24, 1995Inventor: George Hopper
