Granted: 2022-01-17
Abstract: FIELD: smoking devices. 
     SUBSTANCE: group of inventions relates to a vapour supply apparatus, a vapour supply system, and a non-therapeutic method for using a vapour supply apparatus. The vapour supply apparatus comprises a main air flow channel located inside the vapour supply apparatus and extending from the air inlet to the air outlet so that when the user inhales, the air is drawn through said main channel from the air inlet in the direction of the downstream side to the air outlet. The apparatus comprises an evaporator for supplying vapour to the main air flow channel located in or near the main air flow channel, a capturing apparatus located in the main air flow channel for preventing the flow of liquid in the main air flow channel in the direction of the upstream side from the capturing apparatus by retaining liquid, and an air flow sensor for detecting inhalation of the user using the apparatus. The capturing apparatus is located downstream from the air flow sensor. 
     EFFECT: flow of liquid to the upstream side is prevented while simultaneously maintaining the air flow to the upstream side during inhalation of the user, and placement of other components in the electronic cigarette is facilitated.

Abstract: FIELD: agriculture. 
     SUBSTANCE: method of sowing grain crops on slope fields relates to agriculture and can be used in soil cultivation and sowing grain crops on slope fields. Sowing is carried out in strip mini-terraces, the width of which is determined by the installation of furrow formers at a distance from each other, which corresponds to the sowing width of six rows of seeds. Sowing is carried out sequentially at three levels: the first three rows at depth of 6…8 cm, then two rows on the field surface and the last one row at depth of 14…15 cm. At that, furrow formers form furrows with depth of 1…9 cm above rows of seeds sown at depth of 14…15 cm, forming ridges above two rows of seeds sown on the surface of the field. Ridges and furrows prevent processes of water erosion on crops of slope fields. 
     EFFECT: invention reduces water erosion processes for crops on slope fields and increases grain crops yield.

Abstract: A ventilation system with positive and negative ventilation pressures controllable through a control unit is to be improved with respect to its adaptability, in particular in the generation of high pulse repetition frequencies above the natural breathing frequency. A gas transport element is provided in connection with a ring line which contains an inhalation valve in an inspiration branch and an exhalation valve in an expiration branch. The desired improvement is obtained by the fact that the gas transport element is arranged in the ring line with constant direction of delivery. By alternate control of the inhalation valve and exhalation valve in a closed system inspiration and expiration pulses are produced. In addition, a controllable valve unit is indicated in which the inhalation valve and the exhalation valve are actuated as diaphragm valves by combined injector and ejector units of low inertia.

Date Jul. 28, 1988.Boards that have been separated by a chipless cutting method using an inclined blade, are twisted and, in most instances, this twist has to be corrected before boards that have been produced in this manner can be used. An apparatus in which a plurality of pairs of rollers are arranged in tandem withing a main frame is used to do this. Each pair of rollers can be pivotted about the longitudinal axis of the main frame relative to the proceding pair. This forms a board guide channel that extends in the longitudinal direction of the main frame and which is twisted approximately about the longitudinal axis of the main frame. The boards that are to be straightened pass through the board guide channel and are permanently deformed, which compensates for the twist that originally existed in the board.

Abstract: The machine tool (10) comprises a main spindle (26) with tool (20) holder (52) element (66) in a spindle head (18) which is movable in axial spindle direction relative to a frame (16). A mechanism is provided for automatic tool change during a to and fro movement of the head.  This mechanism comprises a carrier (24) which is independently movable parallel to the spindle relative to the frame and holds a rotatable magazine (22) with peripherally spaced positions (96) for releasably holding tools capable of being axially aligned with the spindle.  Head, frame and carrier are coupled via a first cam (162,164) lever (28;167,168,160) unit to move the carrier relative to the frame during the head movements such that the tool in the spindle is engaged by one of the tool hold positions (96), and to move carrier and head apart.  Head and frame are further coupled via a second cam (188,186) lever (30;178,182,180) unit to effect release of the element (66) during part of the head movements.  A stop (90) prevents movement of the carrier a predetermined position whilst the head can move below that position to carry out machining operations.
