Abstract: The substantially leak proof glazing system comprises a plurality of panels, each of which comprises a sheet of glass surrounded by a frame. The frame is formed of two angle members along each edge of the sheet which are slightly shorter than the edge of the sheet so that there is an open diagonal gap at the corner of the panel which leaves the corner open for receiving sealant. A resilient bezel is between each outer angle member and the outer surface of the corresponding sheet. The balance of the space between the edge of the sheet and the angle members is filled with a silicone sealant applied wet and cured in place. Channels in the faces of the bezel permit the detection of gas leakage through the seals. The glazing system has a generally U-shaped bond breaker covering a portion of the supporting structure. A quantity of silicone sealant is bonded between the edges of adjacent panels and the bond breaker, forming a substantially air tight seal between the panels.

Abstract: A data communications system for a computer for transferring data between the memory of the computer and one or more peripheral devices without requiring an interrupt context switch. The data communications system includes a number of specialized registers in the central processing unit of a computer, a computer memory, a data storage location associated with one or more peripheral devices, and a bus connecting the data storage location to the memory. The specialized registers in the central processing unit are dedicated exclusively to processing data transfers between the memory and the data storage location associated with the peripheral devices. Data transfers between the computer memory and the data storage location associated with the peripheral devices are made under the control of the central processing unit with the use of the special registers without the execution of an interrupt context switch.

Abstract: A dispenser for surgical wire has a housing with a cover, the housing having a spirally formed channel therein for receiving guidewire. The housing and cover form an integral cassette. The cassette has an inlet connector through which sterilizing fluid may be injected into the channel and an output port through which the guidewire may be uncoiled from the cassette. A web of the housing is shaped to provide a means of securing a J-shaped tip of the guidewire during transportation so that it does not become unwound inside the cassette.

Abstract: A regatta board game is disclosed in which a rectangular game board is laid off in a grid of squares established by a first series of parallel lines extending in a first direction and a second series of parallel lines extending in a second direction which is normal to the first direction. Some of the squares are designated as falling within a first, second or third category, the first category designating preliminary course marker positions, the second and third categories providing an indication that a player is to draw a card which partially determines the progress of play.

Abstract: The invention is directed to structural elements for use in triangulated structures, and structures assembled from such elements. In particular the invention provides an elongated structural element for use in a triangulated structural assembly, provided at at least one end thereof with connector means adapted for pivotal connection directly to at least one further structural element about a pivot axis which is transverse to the longitudinal axis of the structural element and which is disposed outside the general envelope of the structural element itself. The arrangement is such that from two to as many as one hundred such structural elements may be interconnected at a structural node without the use of an intermediate nodal member.

A variety of shells having different depths, colors and surface finishes are produced for a given size frame, and a variety of combinations of shells can be selected for each box.

Abstract: A cooled vane for a gas turbine engine has a hollow aerofoil with apertures at its trailing edge for cooling air ejection. In order to control the flow of cooling air out of these apertures a metering insert extends between the opposed internal faces of the aerofoil adjacent the trailing edge and accurately defines the required flow areas.In a preferred embodiment the insert is of `hairpin` cross section and defines the flow area as channels between projections from the limbs of the `hairpin` which abut with the internal faces of the aerofoil. A cooling air entry tube then engages with the concavity of the hairpin, and the flow down the two flanks of the tube may be controlled by the flow area provided by the projections on the respective limb.

Abstract: The aerodynamic surface of the kite consists of a single sheet of stiff material arched about a longitudinal axis, being more highly arched at the front end than at the rear and having an aperture located predominantly on the rearward half. In a preferred embodiment, the kite is die cut from a sheet of foamed plastic, and laterally-extending tension members are used to hold the sheet in the arched shape. The flying string is attached directly to the kite for flying it with the concave side upward. Other embodiments can be flown with the concave side down if a bridle is used.

Abstract: A kite having separate forward and aft sails, each arched about a common longitudinal kite axis and each sail disposed concave downward in flight. The concave shape of the sail funnels the wind through the kite. Lift is derived from the central portions of the sail while the lateral portions of the sail, which are nearly vertical and are parallel to the wind direction, provide lateral stability. The proportional lift and weight balance provided by the aft sail, in combination with the bridle arrangement, provide longitudinal stability.
