Abstract: A seal plate includes tear out sections that leave pipe sealing openings, an externally threaded cylindrical portion that extends through a hole in a septic system distribution box wall, a resilient cup-shaped flange that faces one side of the wall around the hole, an internally threaded ring with hand grips that is screwed onto the cylindrical portion against the other side of the wall so that the wall is clamped between the ring and the cup-shaped flange and the flange bends axially, resiliently forcing concentric radially spaced axially extending ridges on the cup shape flange sealingly against the wall.

Abstract: An anchor having an internally threaded first opening, a body, a first end on the body threaded to fit the first opening, a second end on the body, configured to fit an opening in the wall of the mold for extending a first length of the body into the wall, a second opening in the second end extending toward the first end, and a protrusion in the second opening configured for receiving a tool for transferring rotational force about an axis through the first end and the second end for withdrawing the body from the anchor. The protrusion is recessed the first length from the second end. An annular member extends radially from the body, one axial end of the protrusion is at the axial position of the annular member.

Abstract: A mixture of indium metal and titanium metal is fused to the inner surface of a quartz envelope of a mercury vapor discharge lamp.

Abstract: A one-piece molded body includes a horizontal arm that extends into a concave longitudinal recess at the front of the roof of a leaf repellant rain gutter, a vertical arm that contacts the back wall of the gutter and contacts the bottom wall of the trough of the gutter, and by referencing on the contacts, orients a fastener in a fastener support guide portion of the body so that the axis of the fastener extends through the slot opening formed by the longitudinal front of the roof and the longitudinal top of the front of the trough.

Abstract: A connector includes a tubular wall on a first body containing a lamp envelope, coaxially receiving an insulating tube mounted on a second body having a cavity that receives the first body, spring metal strip terminals on the outside of the tubular wall in resilient contact with spring metal strip terminals on the inside of the cavity, and microprocessor controlled heated and cooled air delivered to the lamp envelope by way of the insulating tube in response to a sensor that monitors at least one of lamp amalgam temperature and lamp radiation.

Abstract: A closed end of a one piece flexible elastomeric seal is mounted in one end of a tubular liquid concrete tight frame that is mounted on a removable door of one wall of a concrete wall mold, the other open end of the flexible seal is in liquid concrete tight sealing contact with the other wall of the concrete wall mold.

Abstract: A septic system tank vertical wall has vertically overlapping grooved rings having specific diameters for receiving existing sealing couplers for septic system pipe. One wall of the groove has portions at different angles from the wall. The grooves are at the same depth and discontinuous at their intersections.

Abstract: A method of manufacturing a lens cap (40) for a transistor outline package includes the steps of: (a) providing a main part (2) of the lens cap; (b) providing an upper and lower molds (51, 52) and putting the main part into the molds; (c) closing the molds and insert molding a lens part (3). The product lens cap includes the lens part and the hollow main part, which is adapted for receiving optoelectronic components. The formed lens part includes a ball lens (30) and a sprue filling portion (31). The main part defines an opening (23), which includes a ball lens receiving hole (231) and a sprue (232). During the insert molding part of the process, the melted lens part material is injected through an injection hole (53) into the sprue, and then flows into the ball lens receiving hole, assuring good optical quality of the ball lens.

Abstract: In molding a seal in a concrete wall, the front end of a tubular element is inserted between an outer tubular wall which forms part of the opening in the concrete wall and a conical seal that is integrally molded with the outer tubular wall. The tubular element includes a foot having a fastener portion that is spaced from and coplanar with the back end of the tubular element.

Abstract: A springy panel bridges the ring mechanism housing. It is mounted on the ring halves so that when the ring halves close they cam the panel up the lower curve of the segments, and bow the panel upward away from the ring mechanism housing cover. An element having an upward end cam surface for paper or for a sheet lifter is mounted through two holes in the element on a lower segment of a ring so that one end of the element is inside the ring adjacent to the ring mechanism cover, the other end is inside the ring, adjacent to a line through the widest horizontal portion of the closed ring, and the element bows out of the ring between the two ends.

Abstract: A pair of shock elements mounted on the wheel bearing frame of an in-line skate and attached to a foot platform are configured so that the attachment points of the shock elements to the platform which move in a Z direction are prevented from moving in an X or Y direction from each other and from movement in a Y direction measured from a plane parallel to the plane of rotation of the wheels and from movement in a X direction from a line parallel to the axis of one of the skate wheels.

Abstract: A tubular wall sealed at a first end by an integrally molded annular wall, forming a cap, is cast in the concrete wall of a low pressure vessel, forming a sealed cavity in the concrete. One end of a rubber tubular gland wrapped sealingly around the outside of the second end of the tubular wall is sealed in the concrete by a radially extending cast-in anchor. The diameter of the other end of the rubber tube is smaller than the diameter of the tubular wall of the cap.

Abstract: A method for forming hooks for a hook and loop fastener on an item extending from a portion of the item, forming the hooks with the item from material of the item that is melted into tubelets bent to an included angle of less than 90 degrees, by heat generated by the material in response to radio frequency energy passed into the material.

Abstract: In molding a seal in a concrete wall, the front end of a tubular element is inserted between an outer tubular wall which forms part of the opening in the concrete wall and a conical seal that is integrally molded with the outer tubular wall. The tubular element includes a foot having a fastener portion that is spaced from and coplanar with the back end of the tubular element.

Abstract: A container that is filled from one end with mortar includes a flexible tube at the other end that is elongated in cross section and open at one end. A shoulder on the container is spaced from the opening about the distance of the height of an opening between facing surfaces of adjacent masonry units that is to be filled with the mortar.

Abstract: A cutout is made on the front wall of a substantially straight portion of spacer frame channel, having an apex at the axis of bend of the channel for making a corner of the frame, the edges of the cutout being angled so that they close down to a slot of at least 4 degrees opening when the channel bent on the axis to make the corner, sealant is applied on the front wall of the straight portion across the cutout before bending into a corner.
