Abstract: The process for obtaining fiber-reinforced foams suitable to be transformed nto reinforced solid cellular materials having a density lower than 0.7 kg/l, if inert fillers are not present, and lower than 1 kg/l if inert fillers are present as well, essentially by mechanical incorporation of gas or a mixture of gases into an unsaturated polyester resin containing conventional additives is described. As reinforcing materials synthetic, vegetable or mineral fibers having a maximum length of 3 mm are employed. The mixture of the resin with the fibers, and optionally with the inert fillers, is conveyed by at least one pump to a mechanical foaming device which introduces into the mixture gas in form of small bubbles, homogeneously and uniformly distributed therein.

Abstract: Device for the automatic filling of battery cells with water comprises a filling cup (10) to be inserted into a battery cell and provided with a connection hose (20) for the water supply as well as a valve actuated by a float (62) fitted to a single centering guide rod (56) for easy movement and not susceptible to clogging up, the rod extending through an opening (58) in the bottom (60) of the cup housing (12) and hinged at its upper end to an amplifying lever (54) for the transmission of the float movement to the valve body (46), so that even in the remote possibility of heavy movement of the float guide, the lifting force of the float (62) is sufficient to actuate the valve.

Abstract: A metal hydride container, comprising a heat pipe of annular cross section, a metal hydride filling the central cavity of said heat pipe, closure members serving to close the openings at the opposite ends of said central cavity, a hydrogen passage tube possessed of a shut-off valve and fitted into an aperture formed in one of said closure members and communicated with the cavity of the heat pipe through a partition member pervious to hydrogen gas and impervious to said metal hydride; and a metal hydride heat storage system comprising at least one metal hydride container abovementioned, which is useful for storing solar heat and waste heat.

Abstract: A window-type air conditioner mounting assembly includes upper and lower elongated rails defining a path along which a supported air conditioner is movable between a first, nonoperative position within the room and remote from the window and a second, operative position in which the air conditioner is disposed in projecting relation through the open window. A flap pivotally supported on the lower rails adjacent the window is engageable with the lowered window sash to create an effective barrier against ambient air leakage when the air conditioner is operatively disposed for use; in the first or storage condition of the air conditioner unit, on the other hand, the window sash is fully and normally closeable in front of the unit to thereby assure an effective seal against air leakage and to protect the air conditioner against the weather elements.

Abstract: A bubble-forming composition, suitable for use as a child's toy, comprises an aqueous solution of a cellulose ether and a mono- or dicarboxylated imidazoline derivative of a fatty acid.

Abstract: A convenient baby chair comprises a slidable leaf cut from the top of a table and a seating structure secured to the underside of the table top directly beneath the slidable leaf. As the slidable leaf is drawn out from the table top the resulting opening in the table top exposes the seating structure. The seating structure is constructed so that an infant may be seated facing at or away from the table top area. When not in use the slidable leaf can be pushed back into the table top area and, in doing so, it pulls the seating structure close to the underside of the table top to improve the appearance of the table in this position.

Abstract: An improved retractable knife includes a frontal part of the blade carrier, which has a bottom blade supporting ledge, is embodied as a pallet adapted to firmly mount and support the area of the blade which remains within the handle so that there is no play or rattle of the blade irrespective of whether an apertured or solid blade is mounted on the carrier. The pallet has a plurality of register pins receivable in corresponding notches provided in a trapezoidal type cutting blade at the edge opposite the blade cutting edge.

Abstract: Interactive programming may be provided by the system (26) of the present invention which can enable both manual and automatic selection of various interactive responses from simultaneously transmitted programming on different channels. In a cable television system (20), the channels used to transmit the interactive programming are the midband channels with the selected response being treated by the system converter (26) to convert the individually selected response to a common assigned television channel frequency for ultimate reception and display on the subscriber's television (24, 22). Automatic selection may then be accomplished by the provision of a selection signal from the logic network (48) to a local oscillator (52) which, in turn, generates a beat frequency to be mixed in a mixer (54) with the various midband channel frequencies to convert the selected midband channel frequency to the assigned television channel frequency.

Each of the pseudo video scan lines has a television scan line format and comprises a complete self-contained packet of digital information sufficient to provide an entire displayable row of video data characters, the pseudo video scan line having an associated transmission time equivalent to that of a television video scan line. The packet of digital information comprises at least address information for a displayable row and data information for the displayable characters in the row.
