09/543305

Inventors:

Ronald L. Bowman - Golden CO
Paul G. Swiszcz - Boulder CO

Assignee:

Hunter Douglas Inc. - Upper Saddle River NJ

International Classification:

E06B 936

US Classification:

1601681V, 1601761 V, 1601781 V

Abstract:

A covering for an architectural opening includes a new system for mounting the controls for the covering within the head rail such that suspended vertical vanes are closely positioned relative to the bottom of a head rail and disposed so as to form a continuous and integrated look with the head rail. An improved pantograph is used in the control system with one set of links of the pantograph having tapered side edges to improve stacking of the vanes adjacent to the end of a head rail without sacrificing strength and therefore quality of the control system. An improved operating system in the form of the combination of a tilt wand, coupler and pull cord provides a simplified system for not only moving the vanes along the length of the head rail between extended and retracted positions but for also pivoting the vanes about longitudinal vertical axis between open and closed positions. An improved system for connecting suspended vanes to the control system is also provided with the system being uniquely designed for use with tubular vanes and retains the vanes in a tubular orientation. The tilt wand is connected to the tilt rod within the head rail by an inclined drive connector that enables the tilt wand to be aligned with the pull cord at the location where the pull cord drops from the head rail for manipulation by an operator.

Abstract:

Various embodiments of an architectural covering insert primarily adapted for use in simulated divided light openings is disclosed. The insert includes an outer framework with horizontal and vertical dividers, a plurality of horizontally or vertically disposed shade components associated with one or more dividers and control means for moving the shade components between extended and retracted positions across simulated openings defined by the vertical and horizontal dividers. The shade components can be of the roller shade type or collapsible cellular type with the net result being that, from a visual standpoint, there are shade components associated with each individual simulated opening defined by the horizontal and vertical dividers, as opposed to a single shade that covers the entire architectural opening.

Appl. No.:

09/759894

Inventors:

Ronald Bowman - Golden CO, US

International Classification:

B65D035/38

US Classification:

222/490000, 222/175000, 220/714000, 251/342000

Abstract:

A flexible member is fabricated with side walls forming a chamber which is coupled to a liquid source on one side and has a slit through an end wall on the other side. The end wall is generally curved toward the chamber on its interior surface. The exterior surface of the end wall has ridges adjacent to the slit that extends through the end wall. Deformation of the side walls of the flexible member as by biting causes the end wall with the slit to deform and open the slit which otherwise is retained closed by the walls of the flexible member. This action establishes fluid dispensing from the source through the slit. The thickness of the end wall varies over its distance creating weaken areas in the end wall. These weakened areas create areas in which the end wall deforms opening the slit. In addition to the foregoing, the interior surface forming the chamber has a minimal surface area. The surface is smooth, allowing easier cleaning of the chamber.

Abstract:

The present invention provides mobile sealant compositions that are particularly useful for bicycle tire tubes and the like. The improvements include a novel particulate for use in the sealant composition that is greatly conformable for closing pores in a plug. Another improvement includes a balanced fiber composition as part of the sealant. Also, the carrier fluid is formulated to substantially reduce losses due to gaseous diffusion by preferably utilizing high levels of ethylene glycol, such as greater than about 60 percent.

International Classification:

B60R 900

US Classification:

224 4245R

Abstract:

Disclosed is a lockable clamping apparatus for securing a bicycle to the rail of a pick-up truck bed having a generally L-shaped lengthwise extending portion. The clamping apparatus includes outer clamping means for engaging the outer facing surfaces of the truck bed rail's L-shaped portion and inner clamping means for engaging the inner facing surfaces of the truck bed rail's L-shaped portion. The inner and outer clamping means are movably, preferably pivotally, connected to each other so that they can be moved, preferably pivoted, between an open mounting position and a closed clamping position. The clamping apparatus is mounted on the truck bed rail when it is in its open mounting position. When the clamping apparatus is in its closed clamping position, the first and second clamping means tightly engage the L-shaped portion of the truck bed rail to secure the clamping apparatus thereto. The clamping apparatus also includes lock facilitating means for enabling the inner and outer clamping means to be locked together in the closed clamping position.

International Classification:

B01D 5944

US Classification:

250288

Abstract:

An actuator system is provided which includes a force transfer element and a force receiving element. A viscous material interconnects the force transfer element and the force receiving element. A workpiece, such as a valve member, is connected to the force receiving element. When a controlled force is applied to the force transfer element, the controlled force and resulting movement are rigidly coupled using the viscous material to the force receiving element so that the workpiece can be moved or otherwise operably controlled. When an uncontrolled force is received by the force transfer element, in which the movement of the force transfer element is slow relative to the deformation of the viscous material, there is no coupling of the uncontrolled force and resulting movement to the workpiece. As a result, the actuator system is able to couple rapid movements using the viscous material, while relatively slow movements are not coupled. Uncontrolled forces contemplated by this invention include forces resulting from stress, aging drift, and temperature variations associated with the force transfer element and the force receiving element.

Abstract:

An apparatus is provided for use in determining the components of an inputted gas mixture. The apparatus includes a single piece body or framework preferably made of a high insulating material, such as ceramic. The body includes a number of cut-outs for receiving or incorporating hardware used in generating ions, controlling their movement, and directing them to an ion collector plate. One of the cut-outs formed in the insulating body receives an ion source assembly. Another of the cutouts is a passageway with metallized material coated along the walls thereof for use in generating an electric field. A third cut-out receives and is associated with a magnet assembly used in directing ion movement towards the collector plate. The single body and cut-out construction reduces the number of individual parts, improves the assembly of such parts and reduces adjustment time associated with such parts. The magnetic assembly is formed using pairs of identical parts in a sandwich-like construction to also facilitate assembly of the apparatus.
