Abstract: A double-glazed window frame comprising two parallel glass panes has an internal blind disposed between the glass panes in parallel therewith. The internal blind comprises a succession of collapsible elongated tubular volumes formed from a plurality of plastic strips; each plastic strip having a center section, an upper face, a lower face, an edge adjacent one of said glass panes and another edge adjacent the other of said glass panes; with the plastic strips alternately bonded to one another through the center section and through the two edges. Each plastic strip has a metallic layer deposited on each face thereof, and each metallic layer has a break in continuity between the edge adjacent one of the glass panes and the edge adjacent the other of the glass panes, whereby the coefficient of thermal insulation of the blind is improved.

Abstract: A coal cutting machine 13, a conveyor 12 and a plurality of mine roof supports 10 extend along the face 11 of a coal mine. The operation of the hydraulic jacks of the roof supports are controlled by pilot valves which are electrically powered and rotationally driven. For example, motorized or cam operated pilot valves can be used. Such pilot valves use much less energy than valves controlled conventionally by solenoids, and the electricity supply can thus be at an intrinsically safe level.The operation of the pilot valves include unitary operation of a given support, remote operation of one support from another and sequential operation of a series of supports.

Abstract: The sensor has two sheets (18, 20) of polarized polymeric piezoelectric material secured together with their main uniaxial mode aligned with axis (16). These are connected to an electric oscillator to induce mechanical oscillation of the assembly (10). A third sheet (22) of like material is secured to the sheets (18, 20) but has its main uniaxial mode transverse to the axis (16). Twisting of the assembly due to rotation causes substantial alteration of the voltage induced in the third sheet (22), the voltage being proportional to the rate of rotation.

Abstract: A device for fixing a mud flap has a bracket with an elongated central part, a bracket section provided at one end of the central part which can be engaged with the free edge of the fender fold, as well as a support at its other end. The device also has a pressure member, which can be pressed against the vehicle body by means of a clamping member supported on the support, in order in this way to position the bracket. A fixing member for fitting the mud flap is connected to the device.

Abstract: A cathode ray tube provided on the exterior of its screen with a layer of polymeric piezoelectric material, for example polyvinylidene fluoride. Localized changes in physical stress on the layer, such as by way of localized pressure of heating on the layer, create a charge region which produces alteration of a beam current of an electron beam when the beam scans over the region. This alteration is detected, as by a sensing loop, to produce a data input.

An organic adhesive is disposed between the paper and the fabric and flexibly bonds the paper to the fabric to form a composite. The composite is sufficiently flexible that it may be folded or pleated without breaking and is capable of being used at high temperatures and at high transverse stresses without rupturing.

Abstract: Process for separating a pre-polymerized composite dental filling, such as an inlay, from the hard substance of the tooth using a separating substance consisting of a sol formed from a substance swollen and dissolved in alcohol and forming an organic or inorganic gel. The separating substance is applied as a separating layer to the cavity prior to introducing the composite into the cavity and this facilitates the removal of the composite after hardening in the cavity. The separating layer is removed from the cavity, and the inlay is then cemented into the cavity after being tempered.

Abstract: Device for administering eye drops from an eye dropper bottle comprising a frame having a first ring member configured to fit around an eye of a person, and a second ring member for supporting the eye dropper bottle while drops are dispensed from the bottle into the eye. The frame includes at least two discrete connecting rods connected to the first and second ring members for maintaining the ring members in a fixed spaced-apart configuration with respect to each other. To reduce the risk of contaminating the drops, the device is configured so that there is no surface of the device which is contactable by drops entering the eye. A handle may be connected to the second ring member for facilitating handling of the device.

Abstract: A stocker in a reel supply apparatus can support and deliver various kinds of reels having different outer peripheral diameters. It has a housing mounted on a reversely revolvable cylindrical body. At the both sides of the housing, reel supporting frames are provided in such a manner as to extend toward the opposite directions. Within the reel supporting frame structures, revolvable threaded shafts are disposed. Pushers are engaged with the revolvable threaded shafts in order to move along the supporting frame structures, respectively.

Abstract: A valuable alternative antifungal antibiotic, for treatment especially of candidiasis, particularly vaginal candidiasis, is proposed. The antibiotic is a bile acid or simple derivative (salt or conjugate) thereof. Cholic, deoxycholic, chenodeoxycholic and lithocholic acid are preferred bile acids. The antibiotic is formulated for topical application. It can be used in association with an anti-inflammatory steroid for the treatment of fungal infections of the skin. It is also proposed to inhibit fungal growth in a variety of pharmaceutical compositions (containing some other active ingredient) by including in the composition, or coating a tablet, pill or capsule with, the bile acid component.

Abstract: An anaerobic reactor for treatment of waste water comprises a primary reactor or zone of the suspended growth type and a secondary reactor or zone of the fixed filter bed type disposed directly above and in liquid contact with the primary reactor. Liquid to be treated is fed continuously into the primary reactor and moves upwardly through the primary reactor, then through the filter bed and out via an outlet above the filter bed. Gas generated in the primary reactor moves upwardly through the liquids and through the filter bed, to cause vertical mixing throughout the zones and to keep the filter bed from clogging.
