Patent number: 5313015Abstract: A laminated groundplane structure for shielding electrical equipment such as printed circuit boards has a conductive sheet sandwiched between a soft foam layer and a rigid foam layer. A connection pin coupled to the printed circuit board or the like pierces the soft foam layer to engage in the conductive sheet. The groundplane can include, in order, laminated layers of soft closed cell foam, an insulating dielectric layer, a conductive fabric defining the conductive sheet, and a relatively rigid foam for maintaining a shape in the groundplane structure. The connection pin includes a conductive post protruding toward the groundplane, and a movable conductive shaft which is spring biased to protrude axially relative to the conductive post for piercing the conductive sheet through the soft foam layer The movable shaft resembles a twist drill with an enlarged or barbed head, which passes through the conductive sheet to engage in filaments of the conductive sheet.Type: GrantFiled: December 31, 1991Date of Patent: May 17, 1994Assignee: Schlegel CorporationInventor: William Hoge

Patent number: 5202536Abstract: A seal for blocking propagation of electromagnetic energy through a gap between bodies having conductive surfaces at least adjacent the gap includes an elongated core element defining a resiliently compressible cross section which can be molded, extruded or otherwise formed. At least one elongated conductive sheath portion is attached to the core element at a surface of the core element exposed to the conductive surfaces of the bodies. The conductive sheath portion extends only part way around said cross section and defines ends which are spaced on the core element and are non-overlapping. Preferably, at least one additional sheath portion is attached to the core element and extends between the ends of the conductive sheath portions. The conductive sheath can include metal fibers or metallized resin fibers, woven or nonwoven.

Patent number: 5143666Abstract: An elastomeric strip of substantially U-shaped cross-section is disclosed which is adapted to be mounted on a flange having longitudinally-spaced curved sections. The elastomeric strip includes a support frame having longitudinally displaceable frame portions that are reinforced with longitudinally extending degradable reinforcing material. The reinforced support frame is advanced through an extrusion die where a coating of an elastomeric material is extruded on the support frame to form an elastomeric strip without degrading the degradable material. Longitudinally-spaced regions of the degradable reinforcing material corresponding to the longitudinally-spaced curved sections of the flange are then degraded, allowing the elastomeric strip to more faithfully follow the curved sections of the flange when the strip is mounted thereon.Type: GrantFiled: January 28, 1991Date of Patent: September 1, 1992Assignee: Schlegel CorporationInventors: Michael J.

Patent number: 5105056Abstract: A shield blocks passage of electromagnetic energy through a seam of indefinite length between conductive elements and is adhesively attached to at least one of the elements. A preferably non-conductive adhesive is disposed on a conductive surface of a seal in a discontinuous pattern along the length of the seam, defining area of 5-40% adhesive for physically attaching the conductive surface, separated by 60-95% exposed areas for direct electrical contact. The seal can include a compressible body or can be defined by a conductive sheet, for example a fabric provided with a plating or other conductive coating. The areas of adhesive preferably define longitudinally non-overlapping inclined lines extending laterally across the seam. A release liner can removably attach to the adhesive. In a preferred embodiment the conductive surface is the surface of a compressible seal body, such as a conductive sheath on a compressible core.Type: GrantFiled: October 26, 1990Date of Patent: April 14, 1992Assignee: Schlegel CorporationInventors: William C.

Patent number: 5054162Abstract: An apparatus for offsetting a constant force over a range of movement, includes a power spring or clock spring, defined by a length of resilient material wound in a spiral, the opposite ends of which are attached relative to one of the force and a fixed point, and to a pulley. The pulley is substantially coaxial with the spring and has a rounded outer contour defining a progressively varying slope proceeding axially along the pulley. A flexible cord wraps around the pulley and leads to the other of the force and the fixed point. The opposite (inner and outer) ends of the spring can be mounted such that the inner end of the spring is fixed relative to the fixed point and the outer end of the spring is attached to the pulley. The constant force can be the weight of a window sash, movable vertically in a frame.Type: GrantFiled: August 17, 1990Date of Patent: October 8, 1991Assignee: Schlegel CorporationInventor: Tracy G.

Patent number: 5045635Abstract: A conductive gasket for sealing facing flange plates against passage of electromagnetic and environmental effets has a conductive sheath, for example supported on a molded, resilient foam core, and structure for affixing the seal to conductive elements to be sealed. A conductive coating having suspended conductive particles in a nonreactive binder is applied externally to the sheath in order to reduce galvanic corrosion by isolating the dissimilar metals contained in the sealed elements and in the conductive sheath. The sheath coating is preferably applied as a colloidal suspension of carbon particles, to the entire outer surface of a metal plated sheath and provides a low resistance, environmentally isolated junction between the sheath and the elements to be sealed, excluding environmental electrolytes, while improving abrasion resistance and flame retardant attributes of the seal.Type: GrantFiled: June 16, 1989Date of Patent: September 3, 1991Assignee: Schlegel CorporationInventors: Joseph J.

Patent number: 4955159Abstract: A retaining catch for a tip-out sash provides an automatically deployed retainer mechanism for a sash slidably captive in a window frame or jamb. The sash can be raised and lowered by sliding it along the jamb. A releasable tenon, for example at the top edge of the sash, allows the user to rotate the sash out of the plane of the jamb, facilitating cleaning of the outside. Releasing the sash from the jamb by releasing the tenon activates a mechanism with a distal hook by which the edge of the sash remains captive and displacement of the edge of the sash from the jamb is limited to the unfolded length of the mechanism. The mechanism can be released fully from the jamb by manual action of the user, whereupon the hook returns under spring bias to reside along the edge of the sash.Type: GrantFiled: July 12, 1989Date of Patent: September 11, 1990Assignee: Schlegel CorporationInventor: Tracy G. Rogers

Patent number: 4831779Abstract: An improved self-draining panel threshold combination for a panel such as a door or the like which is of simple design and construction, and passes industry air and water penetration requirements without the use of separate corner seals or door bottom seals. The door threshhold combination comprises weatherseals around the entire periphery of the door lying in a weatherseal plane. An open-ended water trough in the threshold extends from one jamb to the other and lies substantially in the weatherseal plane for catching any water that leaks into and past the weatherseals. The threshold has a weatherseal adjacent the water trough that is adapted when flexed by the closed door to allow entry of water into the open end of the water through, and when unflexed upon movement of the door to its open position to cover the open end to prevent foreign material from entering the trough. A drainage system is provided for draining water entering the water trough out of the threshold.Type: GrantFiled: August 31, 1988Date of Patent: May 23, 1989Assignee: Schlegel CorporationInventors: David W.
