Abstract: ABSTRACT OF THE DISCLOSURE         A plug for a sewer pipe has an inner sleeve with threaded opposite ends.  A pair of longitudinally aligned outer sleeves having cylindrical outer surfaces and opposite end edges are slidably mounted on the inner sleeve.  An inflatable tube is carried by the outer sleeves, the tube having inner and outer walls as well as end folds.  Air valves are fitted to the end folds to admit pressurized air into an air chamber provided within the tube.  The threaded opposite ends of the inner sleeve are each fitted with a collar which is engaged by an end closure provided with an inlet port and an outlet port.  Removable stoppers normally close each inlet and outlet port.  The plug can be inflated within an end of a sewer line to provide a positive leak-proof seal against a head of water.  Also two of the plugs can be connected together in an assembly which allows a sewer line to be pressure tested.

Abstract: ABSTRACT OF THE DISCLOSURE:           A device for passively transporting heat in any direction, particularly downwards, from a heat source to a heat sink, which device comprises a boiler for heating a working fluid, a container for condensing vapour of the heated working fluid, means for transferring the said va-pour from the boiler to the condenser, and means for trans-ferring the working fluid from the condenser to the boiler. The working fluid is compelled from the condenser to the boiler, when the device is in use, by expansion of a com-pressible medium stored in the condensor, which medium is additionally compressed by the vapour of the working fluid when the device is used.  Means are provided for rechanging condensed fluid to the boiler without discontinuing the heat supply to the boiler.

Abstract: This invention relates to a new composite structure suitable for use as a roof or wall of a building. The structure comprises an interior substrate, a layer of rigid insulation having an insulating ability at least equal to one inch of rigid urethane foam, and an adhesive layer bonding the insulation to the substrate. A layer of cementitious material at least one sixteenth inch thick is adhered to the insulation and an exterior layer of the dried residue of a polymer-rich latex coating composition, at least 2 to 4 mils thick is applied to maintain the adhesion of the layer to the cementitious material. This structure demonstrates improved resistance to penetration by fired which may start on the interior side of a building while at the same time, exhibits excellent water resistance, when compared to the structures of the prior art.

Abstract: Docket 2557 SELF-ERECTING ROADWAY MARKING POST                Abstract of the Disclosure A metal anchor tube is driven into the ground or blacktop and defines a cavity which received the lower end portion of an elongated cylindrical flexible marking tube extruded from a resilient plastics material. The upper end portion of the marking tube supports a light reflecting mem-ber which may be in the form of a reflective sheet located within the mark-ing tube and visible through an opening or window within the tube. In one embodiment, the lower end portion of the marking tube is releasably coupled to the anchor tube by an internal wedge plug which compresses the marking tube against the anchor tube and is inserted and removed by means of a tool. In another embodiment, the releasable coupling is formed by an anchor tube having tabs which project inwardly into corres-ponding holes within the flexible marking tube.  A flexible plastic rein-forcing tube extends within the marking tube and assures the self-erecting of the marking tube to an upright vertical position after the marking tube has been impacted and bent by a motor vehicle accidentally passing over the tube.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a blown glass tile which is evacuated for insulating purposes and a method of forming the blown glass tile.  The tile is blown through a opening which is later sealed by means of a pressure pro-ducing source in solid state to form a gas at a temperature below 600°C which is the melting point of glass.  The molded glass is then blown by means of the gas which has been formed from the pressure producing source into a mold to form a tile.  The tile is sealed with the gas trapped therein and thereafter cooled which initially results in solidification of the glass and thereafter sublimation of the gas back to the solid state producing a vacuum within the now formed tile.

Abstract: LOCKUP CLUTCH CONTROL SYSTEM            Abstract:      An electronic control system (30) for a lockup clutch includes a control system for receiving a vehicle speed signal (41) and, as a function of adjustable engagement and release threshold signals, controlling a solenoid valve (32) to engage and release a lockup clutch (22).  The point of lockup is set by a potentiometer (76) to represent a first vehicle speed, and the point of release is set by a variable resistor (77) at a second speed, lower than the first.  The variable resistor (77) is switched into the circuit only after the first threshold level is passed and the clutch is locked up.  A signal from the brake pedal (29) overrides the threshold established in the control system to provide clutch disengagement as soon as the brake pedal is depressed.          Various circuit components protect the control system from inadvertent damage by the driver and/or vehicle maintenance personnel.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a stackable transparent container, a lid therefor, and a method of manufacturing the lid.  The container has walls made from a transparent foil blank and also has at least one connection zone running in the direction of the height dimension.  The bottom of the container is connected with the walls thereof in the area of lower edges therealong.  The container lid has an edge capable of overlapping the upper container edge.  The height of this lid edge, when measured in the circumferential direction of the lid, is smaller than its free edge along the edge zone forming the transition to the lid portion.  The container lid is formed as a deep drawn element and is manufactured in a manner whereby a deep drawable foil is placed in contact with defining surfaces of a depression of a divided tool.  The shape of the depression corresponds to the shape of the lid to be manufactured.  Elements of the tool are held together during the deep drawing process and thereafter such elements are separated from each other so that the deep drawn lid may be removed from the depression.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a method of making electrical con-nections to thin film coatings and the electrical con-nector formed thereby especially useful in a fluid flowmeter. The film with its conductive coating is pressed against a rigid, relatively long, connector bar by conductively coated pads of elastomeric material at a selected con-trolled pressure with the electrical connections to the film coating being made through the bar and pads.  Utiliz-ing this method, localized high stress areas which cause damage to the thin film are avoided, and low current densities are accomplished by the controlled contact pressure over a large area of the film coating.
