Wind energy is converted partly into electrical energy in the form of an alternating current of constant frequency by means of a synchronous or asynchronous generator and partly into electrical energy by means of an additional generator, of which the load is made to vary so as to obtain maximum efficiency of the wind rotor in relation to the available wind. The apparatus comprises a wind rotor con...

The pushbutton unit comprises a number activating buttons, an elastic sheet with for each button a bubble-shaped, spring-back part, and at least one printed circuit, on which there is a contact point corresponding to each button. Between the bubble-shaped parts is an elastic component of electri electrically conductive material which in a first position for the button adopts an unactivated positio...

The invention in question concerns an arrangement on a bed (9), or similar reclining base (10), to facilitate the occasional lifting of a person who is bed bound.The invention facilitates the lifting, in a simple and effective way, of a bed bound person (8) without risk of injury of the person or personnel involved in the lifting.A number of, preferably loop-shaped, lifting devices (2) which stret...

The exhaust gas channel (17) in the combustion hearth with a fluidised bed (11) is inclined towards the bed and communicates with the hearth shaft (10) through a base aperture (21). Dust moving with the exhaust gas is collected in a magazine (23) in the lower part of the channel. In the bottom (22) of the gas channel are air supply mouthpieces (24-26) which force a required amount of dust back to ...

The device comprises a core of magnetic conductive material working in conjunction with relatively moving magnet poles. One (7) of the core (6) parts working with the magnet poles (2,3) is magnetically connected to a laterally positioned arm (9), also of magnetic conductive material, which is displaced in relation to the core part (7) in the direction of the pole movement path. - At least one of t...

The ice breaker vessel has a hull (1) with trim tanks (2) and sway tanks (3). A system to prevent icing comprises a compressor (7) with a drive and at least two air distribution pipes (9) with blowing apertures (10) below the water line. The icing prevention system also has two further air distribution pipes (11) along the hull stem, also below the water line. These pipes also have blowing apertur...

A nut for fastening apparatus parts to a support, and occasionally for transmitting electrical current between the apparatus part and the support, is intended for being placed in a groove in the support. The nut consists of a steel plate bent into a U-shape and having two legs 1 with edges folded outwards and abutting the legs, the folded corners of the legs having points 4, and the part 2 of the ...

The pit latrine emptier has a tank (1) connected via a pipe (2) to a vacuum system (3) such as a standard vacuum truck. Another pipe (8) extends from the tank and is pushed into the pit latrine (9). The vacuum system then creates a partial vacuum in the tank and sewerage from the pit latrine is drawn into the tank. - This system enables the vacuum system to remain in a relatively accessible place ...

The method for making up a ready mixture of baking, filling and moulding masses can be used in the pastry, cakes and biscuits and confectionery industry. The object of the invention using a low technical or technological input is to produce a ready mixture, which is composed of available raw materials, has good keeping properties and can be further processed into a variety of products by the addit...

The combustion hearth arrangement has a fluidised bed (11), and has the bottom (22) of an exhaust gas channel (17) running parallel to the hearth shaft (10) inclined towards the bed. The channel communicates with the shaft through an aperture (21) connected to the bottom. - Any solid matter transported by the exhaust gases is collected in a magazine (23) in the lower part of the channel (17), and ...

In a control device for a variable displacement pump (1) there is an auxiliary pump (5) driven jointly with the latter. Arranged downstream of the said pump is an adjustable restrictor (11). A regulating unit (8) for altering the displacement of the variable displacement pump (1) has a feedback device (15), with the aid of which the restrictor (11) can be adjusted. A comparator (16) ensures that t...
