Abstract: A vacuum cleaner dust bag (10) comprises two portions of air-pervious filtering sheet material (11) joined to form two closed ends (12, 13) and having an inlet opening (14) in one portion for insertion of an inlet tube for entry of dust-laden air into the bag. An elastic plate (16) is attached to one portion of the sheet material (11) in the plane thereof and over the inlet opening (14). The plate (16) has a slot or slit (17) which is distended when the inlet tube is inserted therethrough into the bag, so that the plate seals around the tube. The need to provide the usual cardboard mounting plate is thus avoided. <IMAGE>

Abstract: Solid fuels are gasified to a fuel gas for subsequent efficient combustion causing no harm to the environment by supply of a reaction gas-like oxygen or preheated air, eventually with an addition of recirculated fuel gas and/or water vapor. The fuel is thereby disposed in a uniform way in a limited zone of gasification (8). Gasification is carried out in a pulsed manner by pulsations in the supply of reaction gas at a comparatively high frequency, said pulsation being produced by means of pulsing means (13) or by cyclic variations in the composition of the reaction gas.

Abstract: A wood boiler for solid fuels such as wood, chipping, peat, etc. The wood boiler comprises a combustion chamber, which is effectively insulated with several different layers with different properties, and a heat exchanger with a water magazine. As the combustion chamber is effectively insulated, and no heat energy is taken off directly from the combustion chamber, very high combustion temperatures may be reached. The combustion is divided into primary combustion and secondary combustion, whereby the secondary combustion takes place at temperatures in the order of 1500 degrees centigrade. Hereby, the flue gases become practically free from pollution. The supply of combustion air may be controlled without the combustion temperatures being noticeably affected, and power take-offs as low as 15 per cent of full capacity are possible. The construction of the wood boiler appears from Fig. 1. <IMAGE>

Abstract: In a propeller for use in a ship of the type comprising 4 or more even number blades, at least one of two adjacent blades is inclined forwardly or rearwardly or one inclined forwardly and the other rearwardly so as to make different the rake angles of the two blades. The pitch angle of the rearwardly inclined blade is made larger than that of the forwardly inclined blade. With this construction the mutual interference between adjacent blades is efficiently utilized to prevent decrease in the efficiency even when operating conditions and the diameter of the propeller vary.

Abstract: A racking system for a drilling platform, which serves to move pipe string sections (2) between a position of use and a storage position, where the pipe sections are located in the vertical position in a rack or fingerboard with spaced horizontal parallel fingers. The fingers of the fingerboard (5) are equipped with spring-loaded, deflectable locking bolts (7) which work together in pairs to lock-in a pipe which has entered the gap between the two fingers. As a pipe enters, the pipe itself causes the locking bolts (7) to be deflected, and the pipe may pass one or more pairs of locking bolts to arrive at its storage position in the fingerboard. For removal of a pipe, a specially shaped release head (13) on a pipe handling appliance is employed at the level of the fingerboard, which head is designed to be inserted into the gaps (5'') between the fingers (5') of the fingerboard, thus putting the locking bolts temporarily out of function while a pipe is removed from the fingerboard (5) by the release head. <IMAGE>
