The two parts are formed by moulding a cloth or paper of glass fibre or other suitable fibrous material impregnated with phenolic resin containing one or more frits and ceramic powder or fibre. The two moulded parts are joined together and the resultant cavity therebetween filled with a mixture of phenolic resin containing one or more frits and ceramic powder or fibre, or sodium silicate containing one or more frits and ceramic powder or fibre.

Abstract: A drilling rig for boring holes in the door of a combination safe includes a bracket for clamping the rig to the door of the safe, an upstanding U-shaped drill frame carried by the clamping bracket and a bearing assembly including a drill shaft journaled for rotation in an elongate outer barrel having internal thrust bearings. Axial movement of the entire bearing assembly is effected by rotating the barrel against mating threads carried by the drill frame. Thrust loads are distributed from the bearing assembly, through the drill frame and clamping bracket to the safe. A chuck is provided for fixing a drill bit to the inner end of the drill shaft. This insulates the motor used to rotate the drill shaft from all thrust loads.

Abstract: A new and improved drink holder for adjustable, detachable and stowable mounting upon a tubular member, the drink holder including an elongated connecting member and an adjustable strap which together define a receiving bore for releasable engagement of the tubular member. A platform, spaced apart from the base member, defines a cavity sized to receive a plurality of detachable retaining arms. The plurality of retaining arms are detachably and pivotally mounted to the platform for radial adjustment for receipt of the container therein.

Abstract: A miniature ratchet type electrical switch exhibiting a reduced audible noise level operation having a damping spring incorporated in a ratchet mechanism switch construction for reducing the forces otherwise exerted on the ratcheting mechanism by a main spring during the camming and seating operation of the components with the force exerted by the damping spring opposing the force exerted by the main spring, thereby reducing the noise associated with this function, and including a reprofiled tooth and cam configuration for preventing the jamming of the moving parts. Incorporation of these features in a ratchet mechanism type electrical switch in which the main spring completes the switch circuitry yields a reliable and aesthetically improved switch function with a high current carrying capacity. Switch constructions in both single-pole, double-throw and single-pole, single-throw versions are disclosed.

Abstract: A needle guard for use with hypodermic syringes and the like to prevent accidental puncturing of the skin of a person who comes in contact with a syringe after it has been used. The invention does not inhibit normal use of the syringe, and positively locks the guard in place after use.

Abstract: A catheter coupling system for connecting branch catheters to selected lumens of a multiple-lumen primary catheter. The system comprises a plurality of couplers each including a body having a primary passageway for receiving the primary catheter and a branch having a branch passageway for receiving one of the branch catheters. A fluid flow path between each branch catheter and the corresponding lumen in the primary catheter is established through an orifice in a side wall of the primary catheter which opens into the selected lumen and which is oriented adjacent a junction between the passageways in the coupler.

Abstract: A crane vessel (20) has a temporary load support structure (23) on which to support a load (22) in transit. For installation, the load is hooked up to the vessel crane (21) and the temporary support structure is removed to enable the vessel to set down the load on its tower structure (24).

Abstract: A display system having a single-frame transparency which contains four independent images, each of the images having spaced apart groups of pixels interlaced with the groups of pixels from each of the other images, each of the images being selectable for projection by a movable grid mask, is provided. A method for preparing and displaying four images from a single-frame transparency is also disclosed. The single-free transparency having interlaced groups of pixels from four individual images is formed from four individual transparencies having a copy pattern formed thereon, the copy pattern being divided into spaced apart square shaped groups of pixels defining a matrix of translucent optic segments.

Abstract: A transfer vehicle for use in a system for transferring payloads from an earth-launch vehicle in one space trajectory to another space trajectory. The system includes a space launch vehicle (FIG. 9) with primary propulsion and guidance systems, a transfer vehicle (FIG. 1) carrying a payload which is stowed in the cargo bay during earth-launch and insertion of the earth-launch vehicle into low-earth transfer trajectory. An engine module (FIG. 3) carrie on-board mission equipment, rocket engine, related fuel supply, guidance equipment, attitude control equipment and electrical power supply equipment (FIGS. 11-20). A grapple system on the earth-launch vehicle (FIG. 9) deploys the transfer vehicle and cargo and restows it for on-orbit repair/modification for earth-return. The transfer vehicle may be multi-staged (FIG. 21) and may be provided with multiple engines (FIG. 23).

Abstract: A quick fit lens is provided including a lens body having a transparent face wall and formed with a channel disposed in confronting relationship with respect thereto for sliding receipt of a planar diffuser light panel.

Abstract: A weighing table system in which load cells are disposed between support columns and the load-supporting platform. The load cells are isolated from torsional forces applied to the columns by hub members enclosing the tops of each of the columns. The horizontal top surfaces of the hub members directly support the load cells. The hub member is interconnected with the column for rotation therewith. A pair of arm members perpendicular to each other have inner ends which are fixed to the hub member and extend horizontally outwardly. Rigid horizontal tie-rods have ends affixed to each of the other ends of the tie-rods are fixed to brackets carried by the platform.In a preferred embodiment, horizontal rollers are journaled for rotation in the outer ends of each of the arm members, to contact abutting bearing vertical surfaces and transmit transverse horizontal loads to the hub member.

Abstract: A cleaning tool for cleaning the exterior of tubular members comprising a tubular body having a longitudinal axis along which a central cavity extends with an open end and a closed end at opposite ends of the longitudinal axis. The side walls of the tubular body have a pair of diametrically opposed slots extending from the open end to the closed end. A spindle mounted to the closed end of the tubular body is used for mounting the cleaning tool to a rotatable drive. Brushes adapted for engagement with the opposed slots to prevent rotation are inserted into the tubular body which is then fitted over the tubular member to be cleaned.

Abstract: A fish hold construction for a fishing vessel, wherein the vessel is provided with a longitudinally extending water flume fish alley. Fish move with the help of gravity and water or brine into such fish alley from a plurality of fish storage holds. Water or brine is continuously recirculated through the fish alley to urge the fish along such alley into a fish elevating conveyor for removal from the vessel. A 'tween deck located in vertical alignment with, and above, the fish alley houses pipes, pumps and refrigeration components.

Abstract: The automatic hydraulic valve control apparatus is intended for use in combination with a lavatory waste tank of a vehicle, such as an airplane. The waste tank includes a drain, a rinsing valve, and a fluid pressure charging inlet. The hydraulic valve control apparatus includes a drain control valve biased to be in an open position, a drain valve responsive to opening of the drain control valve and fluid pressure in line, a rinse valve control including a timing circuit to control the amount of pre-charging of the tank once the drain closes, and a drain control valve actuator including a timing circuit operating to close the drain after a desired period of time. An anti-siphon circuit is also provided to allow a given amount of gas to enter the charging line once rinsing and pre-charging of the waste tank are completed.
