Abstract: Layers of carbon with a thickness ranging from 10 nm to 10  mu m with a diamond-like crystalline structure in a vacuum under a protective atmosphere, but also in atmospheric conditions, represent an excellent dry lubricant which is characterized by a very low coefficient of sliding friction ( mu  SIMILAR 0.01 to 0.1) and also by a very high abrasion resistance. The adhesion of the carbon layer to bearing surfaces can be improved by an intermediate layer between the lubricating layer and the bearing surface. The intermediate layer preferably has a lattice structure similar to that of the lubricating layer.

Title: Vacuum circuit interrupter
Inventor: INNAMI YOSHIYUKI
IPC: H01H33/66
Filed: 1980-03-19
Abstract: The invention disclosed a vacuum type electric circuit interrupter comprising a highly evacuated envelope which includes at least one metallic tube (18,20,26,28) made of the magnetic material or the ferromagnetic material, a pair of relatively movable contacts disposed within said envelope in a location and means for eliminating the magnetodistortion of said metallic tube (18,20,26,28). This means comprises a magnetic flux generating member (56) for supplying the magnetic flux to said metallic tube. The noise generated from the vacuum circuit interrupter is, accordingly, eliminated by means of a magnetic field applying member for applying previously the magnetic field to said metallic tube or by increasing the magnetic reluctance of the metallic tube.

Abstract: A method of forming an anticorrosive coating on the surface of a metal substrate comprises coating the surface of the metal substrate with an anticorrosive metal capable of forming an alloy with the substrate metal using a spraying procedure. The coated surface is then heated in a vacuum or in an atmosphere substantially inert to the metal coating and metal substrate by irradiating electron beams or a plasma arc thereonto to form an alloy layer in the interface between the metal substrate and the metal coating. Preferably, subsequent to the coating step and prior to the irradiation step, a solution of a thermally decomposable platinum-group metal compound is coated on the surface of the resulting coating, and the coated product is then heat treated at about 50 to about 300°C.

Abstract: An oscillating pneumatodynamic bearing takes the form of a laminated transducer disc (2) co-operating with a flat surface (16) to form a squeeze bearing. A layer (4) of piezoelectric, magnetostrictive or electrostrictive material is laminated with a layer (6) of another material to provide cupping and uncupping of the transducer disc of the bearing when electrically excited by an oscillator (22), so that the transducer disc is able to fly above the bearing surface on a fluid which is usually ambient air compressed by the mechanical oscillation of the transducer disc at an ultrasonic frequency. The disc is connected mechanically to an object to be supported and to its electrical sources of energy at points along the locus (20) of zero or minimal oscillation. This locus is a nodal circle.

Abstract: fluid piston device including a cylinder (14), a piston 22 axially movable within the cylinder and dividing it into first and second chambers (28,30). Mounted on the piston within the first chamber (28) is a pressure responsive valve (82) which can close off passages (52) passing through the piston. A spring loaded plunger (72) is urged against the valve (82) which in turn is urged downwardly by a lighter spring (86) towards the seated position. The arrangement is such that a piston can operate in a low force rapid movement mode in which the valve is open and fluid passes from the second chamber to the first chamber readily, a moderate force rapid movement mode in which the valve floats and still allows this passage of fluid and a high force movement mode in which fluid pressure in the first chamber holds the valve firmly seated.

Abstract: A feed horn for a reflector-type microwave antenna comprises a smooth-walled conical horn (10) and a lining of absorber material (35) on the inside wall of the horn for reducing the width of the RPE (radiation pattern envelope) in the E plane of the antenna. The lining of absorber material (35) extends from the wide end of the conical feed toward the narrow end thereof, terminating at a point (40) where the horn diameter is about 7 times the longest wavelength of the microwave signals being transmitted. The width of the RPE in the E-plane of the antenna can be reduced to be nearly equal to the width of the RPE of the H plane of the antenna without significantly degrading this H plane RPE from its shape without absorber and without significantly changing the gain of the antenna.

Abstract: The invention relates to a sturdy I-girder. In the previously used corresponding girders, for example in I-girders made of laminated wood, it has not been possible to adjust the dimensioning so that bending stress, shearing stress and bending flexure would all have been equal dimensioning factors, and so it has been necessary to overdimension the girder. The object of the invention is in particular to eliminate this disadvantage and to achieve thereby a considerable saving in material. This is achieved by making the web (u) of the girder from continuous multi-ply wood with 10-60 %, preferably 30 %, of its plies being such that their grain orientation is transverse in relation to the web length and the remainder of the plies being such that their grain orientation is parallel to the web length. The booms(p) of the girder are made from multi-ply wood the plies of which have their grain orientation parallel to the web length.
