Abstract: There is disclosed festoon lighting of the kind referred to whose lampholder fittings comprise a lampholder base including a cylindrical shroud extending from a channel in which a cable may be laid, pins projecting into said channel and a cap having a plurality of angularly spaced depending lugs each with a radially directed tooth on its free end, the cap and base being interengageable by axial pressure to cause the pins to penetrate the cores of a cable laid in said channel and to force the lugs through apertures in a part integral with said shroud whereby the teeth engage with shoulders on the underside of said apertures, the lugs being a close fit within the apertures such that passage of the teeth through the apertures involve elastic deformation of the parts.

Abstract: A laminated playing surface and its method of making wherein a chemically blown polyolefin foam sheet is laminated by an adhesive to a scrim sheet saturated with a stabilizing agent which when heated contracts the lamination so that it can stretch tight between opposed edge portions affixed to the surface of the playing site.

Abstract: A variable suction aspirator head for an end fitting of a suction hose consisting simply of an inner valve tube having wall holes and a slideable outer barrel, permitting variations in suction, the trapping of solid material by the valve tube wall holes and easy disassembly for cleaning and sterilization of the parts after each use.

Abstract: There is disclosed a picture frame comprising a plurality of rebated side frame members at least one of which is provided with a part hingedly connected thereto, and movable between a first position in which it lies outside the rebate and a second position in which it lies within the rebate to engage the rear face of a backing sheet or board, and urge same towards the front of the frame.

Abstract: A thermally insulated ice-cap prevention barrier in an ice bank, extending across the container thereof above a brine-conducting tube bundle immersed in a phase-change material, to prevent freezing of the phase-change material in an expansion space above the barrier and below a cover on the container.

Abstract: A web e.g. a fibre web as used in the manufacture of textiles is inspected e.g. for thickness uniformity or the like by transillumination, where the web is subject to ambient illumination, the transillumination being effected in modulated fashion whereby to distinguish measuring illumination from ambient illumination. Modulation may be effected by time-chopping a beam or by a narrow spectral band filter to improve signal-to-noise ratio.

Abstract: There is disclosed a rigging frame (10) having legs (15) whose lengths are adjustable to suit the frame for different sizes of "big bag" to avoid need for adjustment of the support means of a discharging machine.

Abstract: In a nozzle dam assembly wherein a circular dam faces into a nozzle adjacent its opening and a support frame abuts the backside of the dam and is removably affixed across a ring encircling the opening, apparatus for selectively locating the dam at its optimum sealing position within the nozzle notwithstanding the particular longitudinal profile of the nozzle or eccentricity of the ring-relative to the nozzle opening comprising apparatus for adjusting the dam relative to the frame along the nozzle axis and also vertically and horizontally perpendicular to the nozzle axis.

Abstract: A coolness storage air conditioner appliance in which water is frozen in chambers during protracted charging cycles by refrigeration apparatus of sufficiently low capacity to permit heat discharge into an interior air space and is melted during brief cooling cycles by air circulated through passageways in heat-transfer relation with the ice, the discharged circulated air thereby cooling the interior air space.

Abstract: A child-proofing device for a tape cassette player having a flanged tongue element insertable through a cassette opening past the door thereof and adapted to be pulled back through an exterior block with detent means to hold the door closed, and to be removed by releasing the detent means, pushing the tongue element forward and then pulling it out of the cassette opening as the door is held open.

Abstract: An outer protective tube into which a fiber optic cable is drawn under tension having a multiplicity of protruberances on its inside surface presenting a corresponding multiplicity of discrete spaced non-linear sliding surfaces to said cable to reduce friction and the tension imposed on the cable.

Abstract: A mounting bracket for a bird feeder adapted to be fitted to the outside of window panes divided by a mullion wherein suction cups attachable to the panes are connected by support means to an elongated member so that the elongated member is spaced from and spans the mullion, and the feeder can then be removably mounted to the elongated member.

Abstract: A eutectic composition for coolness storage and its method of making wherein a dry particulate mixture of sodium sulfate and a lesser amount of sodium tetraborate pentahydrate is added to water while the water is stirred, together with a small amount of a buffering acid to reduce alkalinity.

Abstract: There is disclosed equipment for discharging material from an intermediate bulk container having a liner provided with a discharge spout located within an outer bag and comprising a discharge duck and apparatus for sealably connecting the lower end of the spout with the upper end of the duct. Preferably the spout is arranged with an upturned cuff which is clamped between the mouth of the duct and a moveable clamping apparatus.

Abstract: For use with an upwardly open infant seat in which an infant reclines, a removable pliable water-repellent cover adapted to extend loosely and continuously over the entire seat except for a central face opening and having a peripheral elastic element for releaseably encircling the seat to hold the cover in place, the cover being entirely without rigid framing of its own.

Abstract: A tool, particularly a hand tool for opening clams, in which opposed jaw elements are incrementally pivoted closer together by successive opening and closing of handle elements, one fixed to one jaw element and the other pivoted to the other jaw element, with a toggle arm between the handle elements acting as a pawl to advance along ratchet teeth on one of the handle elements.

Abstract: A bird feeder in which different varieties of seed can be stored and distributed through an invertible loading tube into a manifold to which the tube removably connects in various rotational positions and then through chutes to selected seed access stations, the feeder being of modular construction to permit disassembly for washing.

Abstract: There is disclosed a thread friction measuring arrangement comprising first and second strain gauges arranged in a thread path either side of a cylindrical surface against which friction is to be measured so that the first and second strain gauges give electrical outputs respectively corresponding to the tension in the thread before and after turning around the surface, and further comprising electronic components for computing the frictional coefficient of the thread in the surface from the electrical outputs.

Abstract: Apparatus for protecting a mattress from body-liquids and collecting the body-liquids which includes a flexible liquid-impervious laminated mattress pad within the layers of which is a tube accessed from the upper surface of the pad through holes and also continuous suction means for drawing off through the holes and tube any body liquids deposited on the upper surface of the pad.
