Patent GB-2464121-A (GB)
Title: Processes and Apparatus for Cooling
Inventor: COLEMAN TONY
IPC: F25B7/00
Filed: 2008-10-03
Abstract: A of hybrid refrigeration systems. In one embodiment a low pressure booster circuit (10) is linked to an absorption plant (20) to provide cooling at lower temperatures that can be achieved by the absorption plant (20) alone. The combined systems are efficient compared to vapour compression systems, especially when "waste" heat from other processes is used to drive the absorption part (20) of the circuit. The absorption plantn (20) can be provided with heat either by direct firing of a fuel, by waste heat from a combined heat and power (CHP) prime mover (such as a gas engine (30) or gas turbine for example), or by any suitable source of waste heat from another process.

Title: Self-propelled undercarriage wheel having a low profile tire
Inventor: COX RODNEY T
IPC: B60K7/00
Filed: 2007-08-29
Abstract: An undercarriage wheel is disclosed comprising an axle member that supports a drive member, for example but not limited to a compact high torque electric motor, a wheel member driven by said drive member, and a tire attached to the wheel member, wherein the tire bulges in the width dimension of the wheel, wherein the drive member protrudes from the wheel member and thus occupies at least some of the additional width made available by the bulge of the tire. A further aspect of the invention is an undercarriage wheel that comprises an axle member that supports a drive member, for example but not limited to a compact high torque electric motor, a wheel member driven by said drive member, and a low-profile tire attached to the wheel member. Since the profile of the tire is low, additional space is available inside the wheel for the drive member. Preferably, the drive member occupies at least some of this additional space, and has sufficient power to be able to propel an aircraft to which the undercarriage assembly is attached, either alone or in combination with other self-propelled undercarriage assemblies attached to the aircraft.

IPC: F02D35/02
Filed: 2009-09-09
Abstract: A method for estimating pressure in an exhaust manifold of an internal combustion engine, especially a turbocharged diesel engine, having a combustion chamber 20 with an associated exhaust valve, the method comprising the steps of (a) acquiring pressure values within the combustion chamber 20, eg using in-cylinder pressure sensors 21, during an acquisition period (AP) chosen within the time interval when the exhaust valve is open, and (b) averaging the pressure values in a controller 9 to obtain a single pressure value which is representative for the pressure in the exhaust manifold. A costly pressure sensor in the exhaust manifold 4 is thus not needed. The pressure sensors 21 may be integrated in glow plugs. The dimensions of the acquisition period (AP) may be calibrated in real time by the controller 9 is response to engine operating parameter(s) eg engine load and/or engine speed.

Title: Alarm system for an oil-fired heating system that monitors pressure in the fuel supply line
Inventor: JACKSON ALAN
IPC: F24D19/10
Filed: 2009-11-16
Abstract: An alarm system monitors an oil-fired heating system comprising a fuel storage tank; a boiler; and fuel supply line extending between tank and boiler. The alarm system comprises a pressure sensor for detecting the pressure of oil in the supply line; a processor; and an alarm. The processor identifies normal pressure conditions during startup, normal operation, shut-down and rest of the boiler — ideally by analyzing pressure data generated during use of the heating system - and also activates the alarm when a change in pressure is detected that does not correspond to normal system operation. The sensor may monitor absolute pressure or changes therein. More generally, the system lnay monitor the condition of any pipeline and comprise a comparator that simply outputs a signal if the pressure differs from a value expected during normal operation.

Metals other than aluminium or iron can be added e.g. as halides of the metal. When sources of metal are used that result in a formation of chloride ions, the chloride ions are removed e.g. by dialysis or by means of an ion exchange resin. Coating compositions may also contain additives such as resins that improve the wettability and adhesion of the coating e.g. melamine-formaldehyde resins, ureaformaldehyde resins, polyethylene imine, and amino acids such as glycine and alanine or in combination. The compositions can be applied by kiss coating, doctor rolls, gravure rolls, immersion, spraying. The articles may be films, containers, bottles, fibres prepared from polyesters, polypropylene, polyethylene and copolymers thereof including ionomers, a perfluoro polymer prepared from tetrafluoro ethylene and hexafluoropropylene, polyacrylonitrile, polyvinyl chloride, polyvinylidene chloride, polyvinyl fluoride, polystyrene, polyimides, polyamides, cellulose acetate, regenerated cellulose.
