Abstract: The present invention relates to improvements in power assisted positive pressure respirators for use in contaminated atmospheres. The respirator comprises a facepiece 1 having an inlet 3 connected to a pump unit 5 for supplying air to the facepiece which has been filtered by filter means 11 connected to the pump unit inlet. The facepiece is also provided with an outlet provided witha one-way valve 2 which is biased to its closed position and is openable when a predetermined pressure above atmospheric pressure is established within the facepiece. To maximise use of the filter means 11, a one-way inlet valve 13 is provided intermediate the pump unit 5 and the facepiece 1, conveniently at the inlet to the facepiece, which is closed during exhalation by the wearer to thereby cause the pump to be placed in a condition in which, although it continues to operate, no or substantially no air is moved thereby, so that during this period, no or substantially no air is drawn through the filter means 11.

Abstract: In a helical scan video recorder in which the magnetic heads are arranged on bimorph piezoelectric actuators it may be desirable, in order to counteract depolarization of the piezo-electric elements, to bias these elements. This is possible without the use of additional slip rings if the electrode to which the drive voltage is applied is connected, via a diode, to the electrode to which the bias is applied and the bias is applied, alternately with the drive voltage, at instants at which the associated magnetic head is not used. If the (lower) drive voltage is applied the diode is cut off and the bias is isolated from the drive.

Title: Piston-type hydraulic control valve
IPC: F16K11/07
Filed: 1986-04-26
Granted: 1990-09-26
Abstract: A hydraulic piston-valve-type control valve that includes a housing in which a control piston is longitudinally displaceably disposed. By means of annular recesses, and hence control surfaces formed on piston collars about a piston core, the control piston regulates at least one fluid stream that flows through the housing. This regulation is effected by coupling the recesses between the piston collars, while appropriately longitudinally shifting the control piston, with annular control chambers on the housing side. The collars of the control piston are provided with control edges that progressively release the control chambers. The problem with heretofore known valves was that an undesired sudden increase in the flow forces could not be avoided. In addition, the manufacture of the corresponding configurations of the control edges was complicated and expensive. To remedy this problem, the course of the control edges that release or close the control chambers on the housing side, when viewed in the circumferential direction of the control piston, has no segment that extends linearly and at right angles to the center line of the piston. Each control edge follows a symmetrical course relative to a central cross section taken through its circumferential development, and each control edge also at least twice provides for the full cross-sectional opening area of the control piston.

Abstract: The foil has two essentially plane-parallel surfaces of which at least one possesses at least partly a metal coating. The metal coating is protected on its metal surface by a sliding film. In addition, the surface facing the metal-coated surface can be protected by a sliding film. The sliding film should possess a maximum constant thickness of 0,5eta over the entire surface. The process for producing a protection for the foil which is provided at least on its surfaces with a metal coating is characterized by the fact that the metal coating is covered with a sliding film. The foil can however also be provided with a sliding film on the surface which faces away from the metal coating. The sliding film can be vaporized, rolled or sprayed on to the foil or be spread on to it by ultra-sound or electrostatically. Subsequently, the foil is wound on to a roll.

Abstract: The rocket comprises a detonator-carrier rotor pivotingly mounted on a body (1) by means of a shaft (15) and susceptible of pivoting from an inactive position to an active position. An exhaust time delay device (26) enables to brake the rotation of the rotor and comprises a multiplier gear train (27) carried by two platens (36) and co-operating with a rock lever (28). The rotor is integral with a toothed sector (29) in mesh with the time delay device (26). The platens (36) are pivotingly mounted on bearings (14) of the shaft (13), thereby enabling an angular displacement of the time delay device (26) about said shaft to enable an adjustment of the angular meshing distance of the toothed sector (29) with the time delay device (26) and, therefore, an adjustment of the time duration of the passage from the safety position of the rotor to the cocked position. The safety distance of the mouth may thus be adjusted by a low cost and safe device.

Abstract: In the case of the present process, the gases to be drawn off during the smelting of readily smeltable metal, such as for example lead, are not drawn off directly from the space above the smelt but via a closure device which is located in the upper part of the smelting space above the smelt. This closure device is designed in such a way that it does not seal tightly during the smelting operation, so that there is constantly an air stream, if only slight, to the drawing-off apparatus. The closure may be designed as a door, swing door, double door or airlock. In any event, a gas duct leads from the drawing-off apparatus into the space which is arranged behind the non-tightly sealing door on the side facing away from the smelting space. The metal is preferably introduced into the smelting space likewise via the non-tightly sealing closure, which according to the invention has to be closed when the metal drops into the smelt. <IMAGE>
