The inventive method for reconditioning a household ion-exchange cassette for filtering a drinking water and device for removing nitrates from drinking water relate to water filter cleaning and to cleaning, regenerating and disinfecting ion-exchange fillers. The method for reconditioning a household filtering cassette consists in regenerating the cassette ion-exchange filler by filtering a 10 % table salt solution and in disinfecting by boiling water, wherein said reconditioning is regularly repeatable at least one time each two weeks. The inventive drinking water ion-exchange filter comprises a container provided with brackets and a funnel, which is arranged thereon and has an opening for receiving a cassette. Said cassette and the filler thereof which occupies the entire volume of the cassette are made of a heat-resistant materials withstanding a temperature of at least 100 °C. Several hard balls made of an inert material are placed in the ion-exchange filler. The container can be provided with a heating element. The device for removing nitrates from water consists of said filter, a cylinder for measuring a salt quantity and a nitrate sensor.

Described herein are methods and compositions for treating certain retinol-related diseases and conditions by modulation of transthyretin (TTR) and retinol binding protein (RBP) availability in the subject. For example, the methods and compositions provide for therapeutic agents for the treatment and/or prevention of age-related macular degeneration and/or dystrophies, metabolic disorders, idiopathic intracranial hypertension, hyperostosis, and protein misfolding and aggregation diseases. The compositions disclosed may be used as single agent therapy or in combination with other agents or therapies. In addition, described herein are methods and assays for selecting appropriate agents that can modulate the TTR and RBP availability in a subject.

By way of realization of opportunities of a new way of washing of linen with help bubble the activator allowing to fully automate all process of processing of linen without any participation of the consumer from a bookmark before drying with an opportunity of direct connection to any of known ironing installations, it is offered two new variants of designs of SM for full processing linen in weight up to 5 kg distinguished from earlier suggested designs by application of special less labour-consuming and more simple units with overlapping of functions, that, besides reduction in price of manufacture, has allowed to reduce even more weigt, dimensions and the charge of a liquid.

The invention relates to beverage carriers (1) for drinking cups with a number of molded recesses (12), which are arranged in a row, extend between an upper level (14) and a lower level (13), and which serve to hold the drinking cups. Interlinking elements (2) are placed on the longitudinal side of the beverage carrier and are designed for establishing a supporting connection with a second beverage carrier (1'). This enables two (or more) beverage carriers to be interlinked whereby resulting in the formation of a joined beverage carrier with a larger capacity for holding four (or six or more) beverage cups.

There is disclosed a process for encrypting a data stream to secure the data stream for single viewing and to protect copyrights of the data stream. Specifically, there is disclosed a process for protecting streaming multimedia, entertainment and communications in an Internet-type transmission. There is further disclosed a streaming server component operably connected with a streaming server that interacts with a client system that includes a virtual smart card to effect the inventive process.

A lock for locking a door into a doorpost, including a lock casing for insertion into a door, a keyhole in the casing for turning a key and locking the lock, and at least one bolt operatively connected to the casing and to the keyhole that slides out and protrudes from the casing when the lock is locked, for insertion into a corresponding mortise in a doorpost, wherein each bolt has at least one angular, wedge-shaped indentation cut into its surface, the wedge-shaped indentations facing the inside of the door and being inclined away from the doorpost, for engaging the bolts on the flat edges of the mortises in the doorpost when pressure is applied to the lock from outside of the door.

A replaceable LED system adapted to selectively transform the unidirectional glow of the LEDs / LED chips and/or any other semiconductor light emitting device into a more uniform glow for better visual appeal along with providing the system as a shock, vibration resistant and unbreakable unit for wide scale and safe application and use. The LED system of the invention avoids the inherent limitation of LEDs in generating unidirectional glow / illumination and favours a comfortable wider uniform visual glow / illumination from LEDs even in directions other than the direction of installation of the LED. The LED system is suitable for use in domestic applications such as general lighting, decorative lamp, night lamp etc. apart from wide scale applications as indicator systems in industrial and automotive application such as impact resistant and unbreakable front and rear indicator lights in vehicles, signal lights in railways, road traffic and aviation lights and like.

A liquid container detachably mountable to a recording apparatus to which a plurality of liquid containers are detachably mountable, wherein the recording apparatus includes apparatus electrical contacts corresponding to the liquid containers, respectively, photoreceptor means for receiving light, and an electric circuit connected with a line which is commonly connected with the apparatus electrical contacts, the liquid container includes a container electrical contact electrically connectable with one of the apparatus contacts; an information storing portion capable of storing at least individual information of the liquid container; a light emitting portion; a controller for controling emission of light of the light emitting portion in response to a correspondence between a signal indicative of individual information supplied through the container electrical contact and the information stored in the information storing means.

The present invention relates to a method for the preparation of a biological fertilizer comprising subjecting whey to a first fermentation step and the addition of a carrier material to the fermented whey and a biological fertilizer obtainable by the method. The biological fertilizer can be used as a replacement of the present artificial fertilizers thereby reducing many of the environmental problems associated with these artificial fertilizers. In addition, the biological fertilizer according to the present invention can be used in the field of biological agriculture for which, until the present biological fertilizer, no fertilizers were available.
