Patent number: 10274220Abstract: If a load of an indoor space is higher than a predetermined value in a cooling operation, a controller performs a swing control operation to swing a wind direction adjusting slat so that a direction of blown air shifts in a limited possible range. The angle of a lowermost wind direction relative to a horizontal plane in the limited possible range is smaller than the angle of a lowermost wind direction relative to the horizontal plane in the normal possible range. The normal possible range is previously determined to be a range where if the load of the indoor space is lower than the predetermined value, the direction of the blown air can shift upward and downward.Type: GrantFiled: August 2, 2016Date of Patent: April 30, 2019Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Nobuyuki Kojima, Akira Komatsu, Ryouta Suhara, Masaaki Murata, Natsumi Furo

Patent number: 10247416Abstract: In a modulating gas burner, the mixing ratio of a gas/air mixture is controlled over a modulation range of the gas burner by a pneumatic controller. During burner on phases, the combustion quality is monitored via a combustion quality sensor. The combustion quality is used to detect tolerances of the pneumatic controller and/or a potentially changing behavior of the pneumatic controller by checking if the combustion quality is inside or outside a defined combustion quality range. When the combustion quality is inside the defined combustion quality range, the mixing ratio of gas and air of the gas/air mixture is not changed. When the combustion quality is outside the defined combustion quality range, the mixing ratio of gas and air of the gas/air mixture is changed by adjusting a gas throttle to compensate for tolerances of the pneumatic controller and/or for a potentially changing behavior of the pneumatic controller.Type: GrantFiled: March 22, 2016Date of Patent: April 2, 2019Assignee: Honeywell Technologies SarlInventors: Wim Munsterhuis, Gerrit Jan Baarda, Piet Blaauwwiekel, Frank Van Prooijen, Gerwin Langius, Albert Hietkamp

Patent number: 10215409Abstract: A gas lighter valve assembly that can be fitted easily and tightly into a gas lighter body or a well as a free-floating entity not fixed to the gas lighter body or well. The valve assemblies integration as a free floating entity within the lighter body or well avoids the necessity of an interference fit. To avoid the necessity of an interference fit, valve assembly positioning and stability is achieved by the use of an o-ring which is compressed by downward force exerted by a pressing cover upon a bushing or directly upon the o-ring. By eliminating the stress and friction typically caused by an interference fit, the lighter body and reservoir can be made from a variety of materials including non-crystalline resins.Type: GrantFiled: October 12, 2012Date of Patent: February 26, 2019Assignee: SOCIÉTÉ BICInventors: Guy Lefebvre, Yann Lefebvre
