Patent number: 7249493Abstract: A method and apparatus for measuring relative humidity of a mixture that provides a quick response time for thermal lag while affording protection to fragile sensors. In one aspect, the invention is a method for calculating the relative humidity of a mixture comprising measuring a chamber relative humidity (RHC) within a chamber enclosing an humidity sensor; measuring a first temperature (TC) within the chamber; measuring a second temperature (TA) separate from said chamber, said second temperature being the temperature of the mixture; and calculating the mixture relative humidity (RHA) based on the chamber relative humidity, a first value representing the first temperature and a second value representing the second temperature.Type: GrantFiled: June 7, 2006Date of Patent: July 31, 2007Assignee: Nielsen-Kellerman Co., Inc.Inventors: Richard Kellerman, Paul H. Nielsen

Patent number: 7153075Abstract: A press fit fastener (1) includes a shank (2), a head (3) and a press fit portion (4) being located at the shank (2). The head (3) is located at the first end of the shank (2). The press fit portion (4) includes a multiple helical profile (5). The helical profile (5) has a beginning portion (6) and an inclination portion (8). The outer diameter of the inclination portion (8) is designed to increase in a direction towards the head (3) to reach a maximum outer diameter. The maximum outer diameter of the inclination portion (8) is spaced apart from the head (3).Type: GrantFiled: December 8, 2003Date of Patent: December 26, 2006Assignee: KAMAX-Werke Rudolf Kellerman GmbH & Co. K.G.Inventors: Wolfgang Sommer, Frank Wagner

Patent number: 6971662Abstract: A towing device (1) for motor vehicles includes an elongated element (2) having a length, a cross section, a first end portion (13) and a second end portion (5). The cross section of the elongated element (2) at least along a part of the length of the elongated element (2) is designed to be hollow. The first end portion (13) is designed to be connected to a motor vehicle. The towing device (1) further includes a lug (3) being connected to the second end portion (5) of the elongated element (2). Due to the hollow cross section, the mass of the towing device (1) is substantially reduced.Type: GrantFiled: October 7, 2003Date of Patent: December 6, 2005Assignee: KAMAX-Werke Rudolf Kellerman GmbH & Co.

Patent number: 6935822Abstract: A detachable fastener includes a screw element and a securing ring. The screw element and the securing ring each include cooperating wedge-shaped surface tooth arrangements and two different pairs of stop surfaces. The wedge-shaped surface tooth arrangements face one another and form sliding surfaces sliding upon one another in a loosening direction of rotation resulting in an increase of the axial force. The first pair of stop surfaces transmits torque in a tightening direction of rotation. The second pair of stop surfaces transmits torque in a loosening direction of rotation. The stop surfaces are arranged with a clearance existing between one another such that the wedge-shaped surface tooth arrangements can slide upon one another without skipping.Type: GrantFiled: February 6, 2003Date of Patent: August 30, 2005Assignee: Kamax-Werke Rudolf Kellerman GmbH & Co. KGInventors: Gunther Hartmann, Wolfgang Sommer, Frank Wagner

Patent number: 6685409Abstract: A connecting element includes a screw including a head and a shank. The shank has an end, and it includes a shank portion, a threaded portion and a stop element. The threaded portion has an outer diameter, and it includes a thread runout facing the head. The thread runout has an axial extension and a circumference. The shank portion has a diameter which is less than the outer diameter of the threaded portion. The stop element is produced by removing the thread runout at least over a part of the axial extension and of the circumference of the thread runout in a way that the stop element has a diameter which approximately corresponds to the outer diameter of the threaded portion. The connecting element also includes a supporting element being captively connected to the screw and including a narrowing location having a diameter which is less than the outer diameter of the threaded portion.Type: GrantFiled: February 5, 2002Date of Patent: February 3, 2004Assignee: Kamax-Werke Rudolf Kellerman GmbH & Co.
