Title: Method for production of wood powder, device therefor and use of obtained wood powder
Inventor: LAURIS VALDIS
IPC: B27L11/06
Filed: 2002-08-09
Abstract: The invention pertains to the field of production of wood powder and it can be used for obtaining wood processing products containing essential oils. Its object is to widen the field of use of the wood powder and to ensure production thereof preserving the maximum quantity of essential oils in its composition. To produce the wood powder it is offered to use a sawing equipment, drying equipment as well as milling equipment, which includes two disc-shaped millstones. The upper millstone (1) is connected with driving device (2), but the lower millstone (3) is placed in basin (5) with circulating cooling water. The lower millstone (3) is provided with surrounding receiver (5) for wood powder. The method offered is characterized in that primary coarse division of raw material into parts is carried out by sawing them into thin long boards, drying them in shady, naturally ventilated premises whilst the moisture content in the boards is diminished to the quantity of 7 to 8% in respect with the total mass of boards. The dried boards are sawn in small cubic type pieces. After that the milling of the cubic type pieces is carried out so that during the milling process the temperature level is not exceeding 40 0C, preferably over the range of temperature from 18 0C to 35 0C. As the raw material could be used the juniper-three wood. The use of the obtained wood powder is characterized by that it could be used against to harmful insects, for example, for scaring away moths; or it can be used for air refreshment of rooms in the form of composition educing inherent aromatic perfume; but in bathes and bath-houses it can be used in the form of infusion, as well as for rubbing in sore places of human body.

Inventor: KEMNER AXEL
IPC: B60K25/08
Filed: 1992-06-11
Abstract: The invention relates to a method for generating electrical energy from the rotational movement of the axles of vehicles, in particular rail-bound vehicles, by means of a generator arrangement in which in addition to the generation of electrical energy the speed of rotation of the respective axis is determined. In order to provide a method for operating an axle generator arrangement and an axle generator arrangement itself as well as a use of the same which is matched thereto, with which method a separate angle of rotation sensor can be dispensed with and a safe and reliable supply of energy with as constant electrical voltage as possible is ensured in all operating situations, it is proposed that both the generation of electrical energy and the determination of the speed of rotation should take place exclusively by a generator function, the pulse parameters of each induced electrical voltage characteristic being evaluated in order to determine the speed of rotation.

Title: Manufacturing manhole cover frames
Inventor: HARVEY DAVID MARTIN
IPC: E02D29/14
Filed: 1981-10-02
Abstract: A manhole cover frame (F) is moulded in one piece of a hardenable material such as concrete which is poured into a jig (1) and is actually moulded against those surfaces of a manhole cover (C) with which it is to interfit in use. When the frame (F) is matched to the cover (C) used to mould it, there results a perfect fit between the two. The surfaces of the cover (C) which are to seat against the frame (F) are machined prior to use of the cover (C) in the moulding process, so that a closely mated interface is obtained between the cover (C) and the frame (F). Alternatively, the cover surfaces are not machined but are coated with a low-frictional material.
