Publication number: 20230250947Abstract: A connector for a strip of linear lighting includes an outer shell or block and an adapter configured to be removably inserted into a cavity of the outer shell. The adapter may be a printed circuit board (PCB) adapted to mount wires on one side or edge. On the opposite side or edge, a series of contact pins are formed on the underside of the adapter. The outer shell includes a pressure-applying mechanism, like screws that insert through its thickness and are secured in a bar with threaded holes. The adapter is positioned such that the screws bear on and supply pressure to the contact pins. A strip of linear lighting is inserted into a slot beneath the adapter such that the contact pins of the adapter coincide with the solder pads or other electrical contacts of the strip of linear lighting.Type: ApplicationFiled: February 3, 2023Publication date: August 10, 2023Inventors: Kenneth A.

Patent number: 8366018Abstract: Oil intensified common rail injectors that combine a common-rail non-intensified injector with an oil-intensified injector. The invention also uses fuel (common rail) pumps that are commercially available since the injector does not rely on this pump for intensification function. Also, since the pressure of the fuel pump is limited to lower than the intensified pressure, the injected pressure is limited to the unit injector; this eases the rail and tube requirements to this lower fuel rail pressure. The injector operates up to this limited pressure with no intensification. Also a separate oil system is configured to operate a hydraulic intensifier. Thus the system is able to achieve very high injection pressure without common rail pump, rail, fitting and jumper tube limits. The oil system does not need to operate or run unless these elevated pressures are required. Embodiments using direct needle control are disclosed.Type: GrantFiled: June 16, 2009Date of Patent: February 5, 2013Assignee: Sturman Industries, Inc.Inventors: Daniel Donald Giordano, Tibor Kiss, James A.

Patent number: 8302822Abstract: Pressure regulators for beverage dispensers of the type using a high pressure gas cartridge such a CO2 cartridge. The regulators provide a simple, low cost, easily assembled and reliable regulator of particularly small size, facilitated in part by the fact that the invention allows the use of a diaphragm of a particularly small size without necessitating the use of expensive and bulky diaphragm clamps, such as threaded clamps, yet is able to provide a more than adequate seal at both the inner and outer portions of the diaphragm.Type: GrantFiled: March 31, 2008Date of Patent: November 6, 2012Assignee: Sturman BG, LLCInventors: Timothy P. Kranz, Benjamin Grill, James A. Peña

Patent number: 8282020Abstract: Three-way valves having reduced leakage and fuel injectors using the same. Three-way spool poppet valves are disclosed having a spool with a poppet valve thereon cooperating with a seat on the valve housing to provide a substantially leak free valve closing in one direction characteristic of a poppet valve while preserving the advantages of a spool valve. Three-way ball valves are also disclosed having substantially leak free valves closing in both directions, but further including reduced short circuit losses due to direct flow from a high pressure source to a low pressure vent during transition of the ball from one position to the opposite position. Fuel injectors with direct needle control using the three-way valves of the present invention are also disclosed.Type: GrantFiled: November 7, 2011Date of Patent: October 9, 2012Assignee: Sturman Industries, Inc.Inventors: Tibor Kiss, Randall James Strauss, James A.

Patent number: 7341028Abstract: Hydraulic valve actuation systems and methods to provide multiple lifts for engine valves using fixed or hard stops at each lift. The fixed or hard stops provide a very repeatable selection of engine valve lifts dependent on engine operating conditions. For full valve lift, unidirectional hydraulic dashpots are used to decelerate the engine valve, both as it approaches the full lift fixed stop, and as the engine valve approaches the valve seat from the engine valve full lift position. Various embodiments and methods of operation are disclosed.Type: GrantFiled: March 15, 2005Date of Patent: March 11, 2008Assignee: Sturman Industries, Inc.Inventors: Charles Conrad Klose, Randall James Strauss, Oded Eddie Sturman, James A.
