Title: Speed Hand Tool for Studs, Joists, Rafters and the Like
Inventor: PAYNE DOUGLAS
IPC: E04G21/18
Filed: 1993-03-04
Abstract: The present invention relates to a tool for the installation of studs, joists, rafters and like orthogonal elements, that are disposed between headers, footers, plates and like traversal elements in a frame for a wall, roof, partition or the like in an architectural construction.  Such tool can replace the multiplicity of tools presently required for such installation work and comprises an elongated body member having an axis of elongation and a pair of conjunctive members at its opposite ends, one of the conjunctive members including a cradle and the other including a shoulder, the cradle being freely accessible to an uninstalled orthogonal construction element only perpendicularly to the tool's axis of elongation and the shoulder being freely accessible to an installed orthogonal element longitudinally of the tool's axis of elongation; whereby the cradle can be fitted onto a successor orthogonal element for translation and orientation along a plane, and the shoulder can be fitted onto a predecessor orthogonal element to control the final position of the successor orthogonal element.

Inventor: GASLOLI PAUL J
IPC: G02B5/28
Filed: 1992-10-26
Abstract: The present invention describes an optical interference coating useful for transmitting visible radiation and reflecting infrared radiation. The coating is formed from a series of interleaved stacks. The interleaved stacks require only two materials, one having a low index of refraction (L) and the second having a high index of refraction (H). The interleaved stack is made from a first stack of the form (L/a bH L/a) and a second stack of the form (H/a bL H/a). The interleaved stack includes one or more of the combined first stack and second stack in the form [(L/a bH L/a) (H/a bL H/a)]. A stack of the form (L/a bH L/a) is placed on one side of the interleaved stacks to achieve symmetry. The complete visible transmitting and infrared reflecting coating is made from two interleaved stacks centered at different wavelength and a third quaterwave stack of the form (L/2 H L/2) centered at a third wavelength. Each interleaved stack and quarterwave stack includes one or more layers.

Inventor: VARVAT PHILIPPE
IPC: F26B23/02
Filed: 1993-10-18
Abstract: An apparatus for dehydrating particulate material.      The apparatus comprises a channel having an inlet end for receiving particulate material to be dehydrated and an outlet end for discharging the particulate material in a dehydrated condition. A screw conveyor rotatably mounted in the channel advances the particulate material while stirring the particulate material to enhance the release of water and noxious vapours. A fan creates an air current in the channel to entrain water and noxious vapours released by the particulate material. The vapours are directed toward a heating chamber which incinerates dangerous and odoriferous compounds as much as possible.      The resulting gaseous media is directed through a passage in a heat-exchange relationship with the channel to elevate the temperature of the particulate material that is being processed and cause same to release water and noxious vapours. The passage is isolated from the channel to avoid direct contact between the burned gases that are released in the atmosphere with yet unburned gases aspirated from the channel.

Abstract: A call-routing method for a virtual private network consisting of two or more private communication traits which are interconnected via switched connections of a public network as required, wherein to switch the switched connections, a service is dialled which then initiates further switching based on a private numbering plan, characterized in that to establish a connection to a subscriber of the private network, a subscriber of the public network dials the same service which then initiates further switching to one of the private communication units, that the service assigns tariffing attributes to each call initiated by it, and that the service assigns to a call between the private communication units other tariffing attributes than to the other calls. It is also directed to a service computer that supports switching calls both within and outside a private network, with different tariffing attributes assigned to the different type of calls. The service computer switches both calls between private branch exchanges of a private network and calls from outside with the aid of a private numbering plan, the latter being initiated with a different tariff. It is also directed to an exchange having at least one such service computer.

Title: Bonding of thermoplastic and thermoset composite structures to metallic structures
Inventor: MCINTYRE ALLEN J
IPC: B29C65/50
Filed: 1993-04-23
Abstract: Methods for bonding metallic structures to thermoplastic and thermoset composite structures are described. The methods include steps for preparing the metallic structure (14) for bonding by knurling a mating surface of the metallic structure and molding a layer of thermoplastic material (50) over the knurled mating surface to produce a bonding surface. To bond a metallic structure (14) to a thermoplastic composite structures (16), the bonding surface of the metallic fitting is consolidated with the thermoplastic composite structure (50). To bond a metallic structure to a thermoset composite structure, a bonding surface is formed on the thermoset composite structure by partially embedding a layer of dry fibre reinforcement in a thermoplastic material layer, coating the exposed dry fiber reinforcement with thermoset resin, and curing the coating dry fiber reinforcement into the thermoset composite structure. The bonding surfaces of the thermoset composite structure and the metallic structure are then fused together by applying heat sufficient to melt the thermoplastic material layers of the bonding surfaces. A resistance heating element (54) is disposed between the bonding surfaces of the thermoset composite structure (16) and the metallic structure to provide the heat required to melt the thermoplastic material layers of the bonding surfaces.
