Abstract: A device to dispense active substances into rinse water, especially in toilet bowls, with a container for the active substance, wherein the container has an opening that connects with an essentially plate-shaped distributor, and with a device to hold the distributor on or close to the toilet bowl wall. The distributor consists of two essentially plate-shaped elements. There are intersecting grooves, channels or the like between the plate-shaped elements, and a first group of grooves runs outward from the distributor while the other second group of grooves only runs within the distributor.

Abstract: Disclosed is an evaporator for volatile active substances such as insecticides or perfumes. It has a housing containing ports through which the active substance emerges. The housing is made up of at least two housing sections which are movable about a hinge axis. At least one receiving section for an active substance container is provided and includes at least one opening device for opening the container. The operating condition is indicated, and there is a further container holding an indicator fluid which is opened when the evaporator is in use so that the indicator fluid can evaporate over the time period during which the active substance is depleted.

Abstract: To provide an electrical apparatus for vaporizing active substances, perfumes or the like volatile substances, consisting of a housing having an electrical heating means and a container for liquid to be vaporized connectable to the housing, in the container a wick or the like being mounted by means of which the liquid is supplied to the heating means, and the wick passes through the heating means at a through passage adapted to the wick, the heating means further consisting of a ceramic heating body with electrical heating coil let into said body, said coil having a high functional reliability and long life with simple production, it is proposed that the heating body (2) comprises a recess (8) which extends tangentially to its through passage (5) and which is made rectilinear and into which the heating coil (7) is inserted, and which is filled with potting composition, the electrical leads (9) of the heating coil (7) being led out of the heating body (2) substantially coaxially to the heating coil (7).

Abstract: In order to improve an apparatus for the evaporation of active ingredients such as pyrethrum or similar insecticides, air-improving, bactericidal, disinfecting and/or, for example, curing substances incorporated in cellular boards or other solid carrier materials, consisting of a housing in which there is provided a heating means which is arranged behind a housing window, and of a holding means for the exchangeable arrangement of an active ingredient carrier panel in front of the housing window in such a way that an evaporation apparatus which is independent from electrical energy can be achieved while maintaining high reliability in handling, it is proposed that a catalytic, merely glowing, that is flamelessly acting burner 4 with fuel tank 3 be arranged in the housing 1 having ventilation openings 13 at such a distance from the housing window 2 that the hot waste gases from the burner 4 flow through the housing window 2 and activate the active ingredients.

Abstract: An apparatus for the evaporation of active ingredients incorporated in cellulose or some other, at least approximately dimensionally stable carrier material has heating means arranged in a housing to evaporate the active ingredients. A support is provided for replaceably holding an active ingredient carrier above the heating means. The active ingredient carrier is in the form of a column and is optionally inserted replaceably, with its longitudinal dimension placed vertically, in a sleeve which is adapted in its form and dimensions to the active ingredient carrier and is open at the top and bottom. The sleeve is situated inside the housing and spaced apart from the wall of the housing on all sides, said housing having exhaust gas openings at the top.

Abstract: Means for adding disinfectant or the like to the flushing water of a WC comprise two layers, one of which is deep drawn to form a chamber. The other layer seals the chamber. The layer sealing off the chamber comprises a water-resistant material and is provided on at least one of its two surfaces with print or the like. A lower base portion of the chamber serves to enable the storage of the means in an upright position on a shelf or the like.

Abstract: Vaporizer device for volatile active substances such as perfumes, insecticides and other volatiles comprising an upper part having openings therein and a lower part with an absorptive slab thereon, the lower part having a capsule filled with absorptive material disposed therein and which may be removed and replaced as desired and means for maintaining the upper and lower parts in operative relationship.

Abstract: A toilet flush water colorizer comprises a container adapted for receiving therein a flush water-coloring block and having at least one entry opening for admitting flush water thereinto, and outlet means for the discharge of colored flush water from the container, which colorizer further comprises suspending means for suspending the container at the inside of a toilet bowl, a diluting chamber in the interior of the container adapted for collecting drops of color concentrate dripping off a block after each flushing, the outlet means being located in the bottom of the diluting chamber.

Abstract: An insect repellent containing perfume which includes citral, citronella oil, and diethyltoluamide.

Abstract: A solid air-improving composition comprising a carrier material, a volatile active material gradually evaporating therefrom and a gel formed by a paraffin component and a gelifying metal soap is improved by providing a deodorant agent or an odorant agent or a mixture of these agents as said active material, a liquid paraffin having at 20.degree. C an evaporation number ranging from 8 to 1000 based on the evaporation number at 20.degree. C of diethyl ether being equal one, constituting the paraffin component, the metal soap constituting the non-evaporating carrier material proper, and water in an amount sufficient for complete gelling of the metal soap and liquid paraffin; the active agent evaporates from the composition with preservation of the outer appearance of the latter but with shrinkage of its volume.
