摘要:
The invention relates to a backlash-free planetary gear unit comprising a sun gear, an internal gear and at least one planet gear which is in mesh with said sun gear and said internal gear and which is arranged on a planet carrier such that it is rotatable about a planetary axis of rotation, wherein the toothed planet gear has a plane of division which is oriented perpendicular to the planetary axis of rotation and by means of which the planet gear is divided into a first planet subgear and a second planet subgear, wherein the first planet subgear is preloaded relative to the second planet subgear by a spring bar arranged in these two planet subgears substantially parallel to the planetary axis of rotation, and wherein a plurality of spring bars is arranged around the planetary axis of rotation.

An adjustable lumbar support for a seat having a seat frame is disclosed, the adjustable lumbar support including a floating support plate for providing an amount of lumbar support to a lumbar region of a seat, the support plate having a front surface and a rear surface, the floating support plate being attached to the seat frame via springs, the provided lumbar support defining an apex. A first actuator assembly and a second actuator assembly are each operatively connected to the floating support plate via respective first and second cables, the first and second cables being spaced from each other substantially vertically within the floating support plate, the first and second actuator assemblies for selectively actuating the respective cables to selectively move the apex substantially vertically and substantially horizontally forward and back relative to the seat frame. A secondary support plate may be provided, and may be hingedly and/or floatingly mounted. Adjustability may be achieved in terms of back and forth (horizontally), up and down (vertically) and by the vertical height of the lumbar support profile. Accordingly, in some aspects the present invention provides a “six-way” adjustable lumbar support.
摘要:
A contact lens cleaning solution containing an enzyme having proteolytic activity and a surfactant, and optionally also a chelating agent and urea, and a method of cleaning contact lenses utilizing this solution are described. The solution and method effectively remove deposits of proteinaceous material, mucins, lipids and calcium located either on or beneath the surface of the lens.
摘要:
In a process for the dechlorination of gas mixtures containing carbon dioxide and chlorine, wherein in several absorption stages the chlorine is converted with stoichiometric alkali metal hydroxide solution into a carbonate-free alkali metal chloride-alkali metal hypochlorite solution and wherein the required stoichiometric amount of alkali metal hydroxide is introduced countercurrent to the gas stream via the last absorption stage, the improvement which comprises operating the last absorption stage in such a manner that due to free alkali metal hydroxide no alkali metal hydrogen-carbonate is present in said stage.

摘要:
Novel surfactant compounds are provided of the formula R--CO--NH--(C.sub.2 H.sub.4 O).sub.n --CH.sub.2 COOH, wherein R--CO-- is the residue of at least one aliphatic carboxylic acid of 6-22 carbon atoms and n represents a number having an average of 2-10, as well as their salts with alkali metals, ammonium and amines. These compounds possess not only a low primary toxicity, but also a low secondary toxicity for the skin, and accordingly they are especially useful in cosmetic compositions, compositions for non-automatic dishwashing and laundering compositions for the fine laundry.
