1.WO/1989/009673VIEWING OPTICS FOR EXTERNAL-MOUNT ELECTRON BEAM WELDERS

WO - 19.10.1989

Класс МПК B23K 15/00 № заявки PCT/US1988/004007 Заявитель FERRANTI SCIAKY, INC. Изобретатель LAWRENCE, Glen, Sherman

An optical system for use in an electron beam welding machine for viewing workpieces mounted within a vacuum chamber from a position outside the chamber, either before or during the welding operation. The optical system includes an automatic motorized means (24) for adjusting the focus of the system to accommodate different electron beam gun to work distances, and simultaneously to automatically adjust the angle with respect to the axis of the electron beam along which the view of the area being welded is to be observed. A transparent disc (22), which may be rotated step by step about its central axis in approximately 30° increments is mounted so that a portion of its surface near its periphery is interposed in the viewing path (21) so as to shield the optical parts of the viewing system from the vapors and radiations which are generated during the electron beam welding process. A means for illuminating only the area on the work surface which is to be viewed (15, 35, 36) is also provided with a similar shielding means.

2.WO/1983/003285MEANS FOR SAVING ENERGY IN A HYDRAULIC CIRCUIT

WO - 29.09.1983

Класс МПК F15B 11/16 № заявки PCT/FI1983/000024 Заявитель VALMET OY Изобретатель MÄNTTÄRI, Erkki

A means for saving energy in a hydraulic circuit where pressurized oil supplied by a hydraulic pump is used to activate various functions by the aid of one or several valves (2, 3, 4) controlling the function. A hydraulic circuit like this is in particular used in agricultural tractors, where the pressurized oil comes from a hydraulic pump driven by the engine. The problem is then that one is compelled to run the pressurized oil through a pressure regulating valve, thereby causing unnecessary waste of energy and need to cool the oil. This drawback is eliminated, as taught by the invention, in that to the hydraulic circuit has with a view to saving energy been connected a free circulation valve (1) which has been connected to cooperate with the valves (2, 3, 4) controlling the different functions in such manner that when one, even if only one, of the function-controlling valves (2, 3, 4) is open the free circulation valve (1) is closed and that when all function-controlling valves (2, 3, 4) are closed the free circulation valve (1) is open.

4.WO/1989/001436A METHOD OF CONTROLLING A TRANSPORT MEANS AND A TRANSPORT MEANS FOR EFFECTING THE METHOD

WO - 23.02.1989

Класс МПК B62D 13/04 № заявки PCT/FI1988/000127 Заявитель TECO-SYSTEMS OY Изобретатель VÄNNINMAJA, Pekka

A transport means (1) comprising a body (2) and several wheels (3a to 3h) positioned in the longitudinal direction one after another on both sides of the body and turnable about vertical axes (4a to 4h). The transport means (1) is supported at one end turnably by means of a tractor means (6) by means of which the direction of travel of the transport means (1) is controlled. In order that the transport means could be controlled more easily, a control sensor (7) is mounted in a swing joint (5) connecting the transport means (1) to the tractor means (6), which control sensor indicates the angle (α) of turning between the tractor means (6) and the transport means (1), whereby the sensor (7) together with an adjusting means (8) controls the turning of the wheels (3a to 3h) in proportion to the angle (α) of turning. When the angle (α) of turning is, e.g., no more than 20°, the adjusting means (8) controls the wheels (3a to 3h) so that they turn in such a way that the transport means (1) turns about a centre (9) of turning positioned in the middle thereof in the longitudinal direction, whereby the turning radii at the front and rear end are substantially equal. When the angle (α) of turning exceeds 20°, the position of the centre (9) of turning is shifted in the longitudinal direction of the transport means (1) in proportion to the value of the angle (α) of turning towards the rear end of the transport means (1), whereby in parking situations it behaves similarly as a conventional trailer, but the axes of all the wheels (3a to 3h) go through the centre (9) of turning, whereby the wheels always rotate without sliding.

Es soll ein eine Fadennaht mit Nahtüberstand abdichtendes Abdeckband aufgeschweißt werden. Das Abdeckband (A) wird durch einen Führungsapparat (18) geleitet, der im Mittenbereich des Abdeckbandes (A) eine U-förmige Falte (F) erzeugt. Zwischen dem Nahtüberstand (U) und der diesen mit Abstand überdeckenden Falte (F) wird während des Schweißvorganges ein Luftstrom hindurchgeleitet, der bewirkt, daß das Abdeckband (A) vom Nahtüberstand (U) getrennt gehalten und nicht mit diesem verschweißt wird. Das Verfahren ist zum flüssigkeitsdichten Abdichten von beschichteten Sitzhüllen vorgesehen, die anschließend mit einem expandierenden Schaumstoff ausgefüllt werden.
