Patent number: 8066922Abstract: In the production of elongate plastic profiles (10), which usually takes place by the pultrusion process, the cured plastic profile (10) emerging from a die (14) is pulled through the stationary die (14) by a take-off device. This process only makes it possible to produce straight plastic profiles (10). The invention envisages producing curved plastic profiles (10) by using a die (14) corresponding to the curvature of the plastic profile (10). For moving the cured part of the plastic profile (10) out of the die (14), it is provided that the die (14) is moved back step by step in relation to the stationary plastic profile (10) counter to the direction of production (19). In order that the plastic profile (10) remains stationary in relation to the die (14) as this takes place, it is securely held outside the die (14) by a holding means (20) during the moving back of the die (14).Type: GrantFiled: March 12, 2008Date of Patent: November 29, 2011Assignee: Thomas GmbH + Co.

Patent number: 7571501Abstract: The invention provides as a connecting element at least one flexural pull element (29) disposed between the pivotable back element (13) and leg element (15) of the support (12). Such a flexural pull element, which can be a cord or belt, for example, can be arranged in a space-saving manner under the support (12) and integrated in a frame (11) of the bed or cot. Thus, no space is taken up by the pull element beneath the frame (11). The invention thereby provides a connecting element of simple and space-saving design which allows for the simultaneous pivoting of the back element (13) and leg element (15) of the support (12).Type: GrantFiled: October 6, 2006Date of Patent: August 11, 2009Assignee: Thomas GmbH + Co.

Patent number: 7494075Abstract: A pressure regulating valve reduces the increased internal pressure in an aerosol spray can, filled with compressed gas, to a working pressure level for a spray valve (12). A regulating piston (52) is kept in equilibrium by a restoring force, and a sealing point (66, 68) is provided, which is closed at a pressure in the pressure regulation chamber (84) that is above the regulated pressure level. To prevent the precision of regulation from being adulterated by the decreasing internal pressure of the can as its contents are progressively withdrawn, a sealing means (86, 66; 67) is proposed, which seals off one free end of the piston (52, 74) from the internal pressure of the can and the regulated pressure. The variable internal pressure of the can is therefore no longer able to act on any axial face of the piston (52), and despite what may be a smaller piston face area, the precision of regulation is improved.Type: GrantFiled: June 30, 2003Date of Patent: February 24, 2009Assignee: Thomas GmbHInventor: Heinz Schneider

Patent number: 6877643Abstract: The spray can has a valve disk (12) with a valve, which valve disk is formed with a valve dome (16) and a fastening collar (18) surrounding it at a radial intermediate distance. The valve is actuated by pushing down a rotatable spray head (22) seated on a tappet (20). For obtaining turning stops for an actuating position and a closing position without taking special steps on the valve disk (12) or can body (10), it is provided that a stop ring (30) is arranged, fixed against relative rotation, in the annular space between the valve dome (16) and the collar (18). For being adaptable to materials of different thickness of the valve disk (12), it is formed with lamellas (35) at the outer circumference, is pushed with press fit into the collar (18) and has a cam track (36) with at least one recess extending along the circumference. The spray head (22) is formed or connected with at least one cam (46, 48). It acts together with turning stop faces (56) on the stop ring (30).Type: GrantFiled: August 3, 2001Date of Patent: April 12, 2005Assignee: Thomas GmbHInventor: Heinz Schneider

Patent number: 6802461Abstract: For a pressure reduction, an aerosol spray can filled with a compressed pressure gas requires, upstream of its spray valve (14), a pressure regulation valve (10) with a closing point (28). In known embodiment types a flow occurs around the outside of the pressure reduction valve, which requires a complicated housing structure. It is therefore proposed that the connection between the closing point (28) and the spray valve (14) take place via a central bore (58) in the piston (22) of the pressure reduction valve (10), preferably without a flow through the pressure chamber (26), but instead past the latter. The simple construction is advantageous, with which it is also possible to provide easy access to the piston (22) from the outside in order to maintain it in its opened position for easier filling under pressure.Type: GrantFiled: April 16, 2003Date of Patent: October 12, 2004Assignee: Thomas GmbHInventor: Heinz Schneider
