Title: Method and device for motor-braking by means of a multi-cylinder internal combustion engine
Inventor: HAKANSSON OLOF
IPC: F02B3/06
Filed: 1993-05-27
Granted: 2005-04-12
Abstract: A method for engine retardation with a multi-cylinder combustion engine, which for each cylinder with matching piston has an exhaust valve for control of the connection between a combustion chamber in the cylinder and an exhaust system. Opening of the exhaust valve for engine retardation is achieved by regulation of a clearance in the engine valve mechanism and thereby engaging one or more extra cam ridges on the engine camshaft, which continuously activates the valve mechanism in dependence of the momentary position of the engine crankshaft, using an actively adjustable, hydraulically operated clearance regulating device. For active control of the engine retardation said device is adjusted between different positions by means of a hydraulic fluid pressure lower than a maximum value controlled by a pressure relief valve. The angular position of the camshaft, at which the exhaust valves are being opened by said extra cam ridge or ridges is depending on the momentary clearance in the valve mechanism. The clearance is gradually brought to zero or close to zero while the pressure in the corresponding clearance regulating device is limited to a certain predetermined value. Independently of when in time during the cylinder work cycle the engine retardation is initiated or terminated, the risk of an opening against a, form a stress aspect, too high cylinder pressure is herby eliminated.

Abstract: A telephone network carrying a facsimile transmission transmitted by a user from a facsimile transmission source modifies the user's facsimile transmission by incorporating with the user's facsimile information at least one advertisement, so as to form a combination facsimile transmission that is transmitted to a destination specified by the user. Ultimately, when the facsimile is printed or displayed, the advertisement will be printed or displayed as well. One or more "sheets" of facsimile information contained within the original facsimile transmission of the user may have an advertisement included therewith. The advertisement incorporated with each sheet may, but need not, be the same. The particular advertisements being incorporated with the user's facsimile information are independent of the content of the user's facsimile information, although they may be selected as a function of one or more parameters of the call over which the facsimile transmission travels. Depending on the option chosen, the advertisement may a) be placed into any available "white space" in which it will fit on the sheet of the facsimile information, i.e., the advertisement will not overwrite any of the user's facsimile information, b) be placed in available white space only in the margin areas of the sheet, or c) the image of the sheet may be shrunk slightly and the advertisement placed in the resulting available white space. Optionally, in exchange for agreeing to the inclusion of the advertisement the facsimile transmitter and/or the facsimile receiver are granted a discount on the cost of the call.
