The invention relates to a propellant-free inhaler which has a storage chamber (6) for a powdered substance to be inhaled, which is associated with a metering device (8), which is manually operated by means of a button, having a metering chamber (7) for receiving a given dose of the powdered substance. The device also has a lateral mouth piece (11) for active breathing in, with an air channel (7) for distributing the particular dose of the powdered substance in the air stream. To ensure that the dosage provided is highly reproducible, a high proportion of this dose leaves the inhaler and the medicinal substance is reproducibly dispersed, a trigger operated pump (12,19,20) is provided which can be manually primed before the inhalation process by means of a button (1,42) and which can be actuated in synchronism with the breathing, thereby generating a current of foreign air which disperses the metered substance.

Process for restrengthening damaged paper, in which the aged, acid-damaged friable paper is treated with a solution containing isocyanate or with isocyanate vapour. Isocyanates having two or more isocyanate groups are preferably used.

A neutralizing agent for effective but mild mass de-acidification of books and other paper products, consisting of a solution of one or more kinds of double alkoxides, each with one alkoxide of a metal promoting solubility, such as group IV metals, aluminum or tin, and one alkoxide of a metal binding the acids in the paper, such as alkali or alkaline earth metals, wherein a non-polar solvent can be used, which exhibits good compatibility with the archive materials.

Neutralizing agent for paper products

A heatable pipette apparatus, includes a pipette tube having a first zone and second zone. The first zone includes a tip end and a first heater for heating the first zone. The second zone includes a second heater for heating the second zone. Regulators are provided for separately regulating the temperature of the first heater and the second heater, the first heater being able to more accurately and precisely alter the temperature of fluids in the tube to reach a predetermined temperature.

Process and device for the nonpolluting mass deacidification of books and other printing and paper products with the predrying of these products by high-frequency radiation in a vacuum, then the application of a neutralization treatment with solutions for deacidification and the subsequent drying of solvents used also by high-frequency radiation in a vacuum. Preferably a single treatment chamber (1) for predrying, neutralizing and drying is used. The interior space of the treatment chamber can be exposed to high-frequency/microwave radiation of a generator (2), to which devices (4, 8, 9; 10 to 19 and 5) combined into a closed movable unit with chamber (1) are connected for the supply and removal of the solutions, for the evacuating of air and for the environmentally favorable separation of vapors when drying the accumulated exhaust air. The process and the device make possible a quick and efficient, as well as nonpolluting, mass deacidification with nearly complete recovery of the solvents.

A filter bag is positioned inside and fastened to a holding frame. The holding frame has substantially vertical walls and is adapted to be placed on the edge of a coffee cup or the like. The sides of the holding frame that face the filter bag are made of hydrophobic material. The filter bag is made of nonwoven hydrophilic filter material.

Disclosed is a composition and a method for covering the sump in cavities serving to store gaseous or liquid, non-aqueous substances, using a so-called geologically old crude oil to which is added a reactive component which combines with the functional groups thereof and blocks them. Particularly suitable reactive components are isocyanates and epoxy compounds.

Composition and a method for covering the sump in cavities

A method of covering the sump of underground cavities which serve to store gaseous or liquid non-aqueous substances. The sump is covered with a layer of highly viscous crude oil which is at least 1 cm, and preferably 20 to 50 cm, thick. The crude oil contains not more than 7% hydrocarbons having up to 5 C atoms in a molecule thereof. The crude oil has a specific gravity of 20.degree. C. of at most 1.2 g/cm.sup.3.
