Abstract: A device for transferring a film from a carrier strip onto a substrate such as a sheet of writing or drawing paper comprises a housing in which a supply reel and an empty reel are arranged. The film-coated carrier strip is guided over an applicator foot which is looped around by the carrier strip with a clip-type slide element of a friction-reducing material secured to the applicator foot. The applicator foot comprises a pivotally hinged extension arm having an end in the end portion for receiving profile member for the slide element.

Abstract: A reinforced beam has an internal I-beam structure with opposed adhesive foam layers. The foam layers are extruded, cut to length and placed on opposed surfaces of the I-beam. When the reinforced beam is heated. The adhesive layers expand to secure the I-beam in place.

Abstract: The joint reinforcement member for a hollow structure of an automotive vehicle has a carrier portion with an outer surface. The carrier portion has a base portion with a first extension having a first longitudinal axis and a second extension having a second longitudinal axis. The first longitudinal axis and second longitudinal axis correspond to the hollow structure. A thermally expandable adhesive layer is disposed on the outer surface of the carrier portion and substantially covers the outer surface. A method for forming the joint member includes providing a carrier having a plurality extensions extending from a base portion that correspond to the hollow structure a layer of thermally expandable adhesive materials applied to the carrier portion. The carrier portion is heated to activate the adhesive layer. The adhesive layer is cooled so that the adhesive layer is bonded to the structural member.

Abstract: A laminate reinforced beam assembly includes a beam having a channel shape defined by spaced side walls. The beam has a contact location where it would be subjected to a point loaded force. A reinforcement layer is provided on each of the side walls. The reinforcement layer is made of a polymer which forms a structural foam in its cured condition and which has a shape wherein its side edges taper toward each other in a direction away from the contact location.

Abstract: A three-dimensional laminate beam is formed by inserting a preformed foam core insert within a hydra-formed metal section having curved three-dimensional geometry. A reinforcing polymer is pumped in and around the foam core insert so as to be adjacent the inside wall of the shell. The polymer bonds to the inside wall of the shell upon the polymer being cured.

Abstract: A reinforced structural member has a channel-shaped laminate structure of a metal stamping, a channel-shaped foil and an intervening layer of structural foam. The reinforced structural member is formed by pressing a foil/resin preform into a channel and thermally expanding the resin to form a structural foam.

Abstract: A method for reinforcing a selected portion of a structural part utilizes a flexible tube having a unexpanded, preferably thermally expandable resin sheath. The sheath may be limited to a selected region along the length of the flexible tube. The flexible tube is inserted through a curved passage and conforms to the geometry of the part to be reinforced. After the portion of the tube having the sheath reaches the desired location, the tube is secured in place. Upon heating, the resin expands to several times its original volume and fills the structural cavity only at that region.

Abstract: A stiffener is provided for reinforcing a hollow structure having a pair of spaced walls. The stiffener includes a carrier member with a layer of expandable polymer which creates a structural foam when the polymer is later expanded. The stiffener could comprise a single laminate shaped to fit in the appropriate locations of the hollow structure so that when the polymer is expanded it forms a structural foam intimately bonded to the pair of spaced walls. The stiffener may also be in the form of a corrugated frame wherein individual laminates are provided with notches to permit the individual laminates to be interlocked with each other at the notches.

Abstract: A laminate for reinforcing a structural member having a plurality of side walls comprises a carrier having at least one inclined support surface. Each support surface has an outer edge disposed toward a respective side wall. A layer of extruded uncured structural foam is on each support surface and terminates inwardly of the outer edge. The foam expands when cured and tumbles down the inclined support surface of the carrier to become bonded to the side wall as well as the carrier. By being spaced from the outer edge of the support surface, the tendency for the foam to wipe against the side wall is minimized as is the tendency for a worker to touch the foam when the worker places the carrier into the structural member.

Abstract: A laminate bulkhead comprises an expandable polymer sandwiched between two stiff members which are of a structure so that the expandable polymer is flared out or thicker in the area or along the line where the polymer expands and is bonded to the walls of a hollow structure in which the bulkhead is placed. The direction of expansion of the polymer results from the polymer being constrained by the stiff members on either side of the expanding polymer.

Abstract: An adsorption agent is introduced in the insulation chamber of a vacuum insulated double walled vessel for the storage of low-boiling liquefied gases. Specifically the adsorption agent is installed in the chamber before producing the vacuum by housing the agent within a gas and water tight container which bursts in a vacuum.

Abstract: A process for the thermal cutting of profiles with a cutting torch which is guided by a control unit in accordance with the workpiece contour includes storing the contour in the control unit. The absolute values of the profile are determined by means of measuring devices in the vicinity of the profile. These values are transmitted to the control unit for determining the actual workpiece contour and the control signals for the torch.

Abstract: A device for generating a dry cold gas flow by evaporating a low-boiling liquefied gas for cold therapy for rheumatic diseases includes a vessel for accommodating the low-boiling liquefied gas. A hose line is connected to the vessel with an interchangeable treatment nozzle for distribution of the evaporated gas. The vessel has only a small storage volume, and in the vicinity of its bottom, it is provided with an adjustable electrical heater for evaporation of the liquefied gas. The hose line is connected to the vessel by means of an adjustable electrical heating line.

Abstract: A heater is provided for heating an unwound portion of a web supported at a holder on a rotatable roll. A first pair of rollers between the holder and heater pull the web from the roll. A second pair of rollers advance the web after it passes through the heater.

Abstract: A device for protecting the gas cylinder valve of a steel cylinder has a neck ring for screwing on the protective device. The protective device is in the form of a clamp collar having a protective strap which surrounds the gas cylinder valve.

Abstract: A device for the partial simulation of climbing includes a frame having a vertically adjustable step and an upstanding handle to permit the user to simulate climbing by stepping up and down the step. Continuous or full simulation of climbing is achieved by a device which has vertically movable steps so that the user may remain at one location while continuously going through the motions of stepping upward.

Abstract: A device for producing ozone is characterized by an inner electrode made from a plurality of metal wires. Accordingly, the diameter of the outer electrode is correspondingly reduced. The ratio of the outer diameter electrode to the inner diameter electrode is greater than two.

Abstract: A prosthetic knee is implanted after cutting the femor and tibia in the proper manner with the aid of instruments which include axial alignment guides and a series of cutting jigs.

Abstract: A highway pavement of concrete slab-on-grade surface includes a prestressed portland cement concrete surface layer which is mounted on a non-freezing low restraint support grade layer without any linear physical connection thereto in such a manner as to permit freedom of movement toward the midpoint of the surface layer. The surface layer is thereby able to slide in response to temperature and moisture changes in the environment including at temperatures below the freezing point of water. The surface layer has a riding surface of generally the same rideability five years after installation as it does at the time of installation.
