Inventor: TAYLOR RUPERT MAURICE
IPC: F02M55/02
Filed: 1984-04-16
Abstract: The pressure pulses travelling along fuel lines to fuel injectors produce noise when the engine is running. In order to reduce this noise attempts are made to modify the shape of the pulse pressure front before it reaches the cylinder. In particular, it is desirable to reduce the rate of rise of the pressure front which in turn reduces the fuel mass flow rate into the cylinder. This has an effect on the combustion propagation within the cylinder combustion chamber and thus reduces noise. 
     To achieve this desirable end, a filter 14 is positioned in the fuel line between the injector pump 10 and the injector 18. This filter has an internal chamber in which the pressure pulse is reflected and then interferes with itself to construct a new pulse of a desirable form.

Abstract: A radio transmitter for transmitting a PM (phase modulation) signal includes a spectrum scrambler (22) for relocation of the input signal spectrum for privacy purposes. A differentiating circuit (21) is coupled to an input terminal (20), and the spectrum scrambler is coupled to the output of the differentiating circuit. An FM (frequency modulation) modulator (23) is coupled to the output of the spectrum scrambler. Due to the connection of the differential circuit before the spectrum scrambler, the modulation index of the modulated PM signal, and/or the frequency band of the modulated PM signal, does not increase irrespective of the provision of spectrum scrambling.

Abstract: For the purpose of lubricating a cavity, particularly an annular cavity in a tool for forging blanks produced by powder metallurgy, a lubricant spray is directed towards a limited portion of the cavity surface and the nozzle is displaced such that impingement area of the spray against the cavity sweeps over the entire surface of the cavity. The impingement surface of the lubricant spray is adapted to cover the radial extension of the annular cavity, the nozzle being displaced along the periphery of the cavity. An apparatus for carrying out the method includes a carrier (10) with a mounting (11) for a swinging arm (12) carrying a spray nozzle (14). The carrier (10) is adapted for being positioned for mounting of the arm coaxial with the axis of the cavity, the arm (12,13) being arranged for positioning the nozzle (14) over a peripheral portion of the cavity. Means (31) are arranged for causing the nozzle (14) to circulate along the periphery of the cavity.

Abstract: @ A tool and its method of operation for removing hollow plugs (14) which have been mechanically expanded into tubes (12). The tool includes an electrical welding electrode (54) having a tungsten tip (56). The electrode is positioned within the plug and rotatably withdrawn therefrom while energized, so that an electrical arc is struck between the electrode tip (56) and the inner wall of the plug (14), thereby melting the metal on the inner surface of the plug along a spiral path. This causes the plug to heat shrink back to its approximate size prior to when it was expanded into tight engagement in the tube end. The plug can thereafter be easily removed from the tube by means of a simple gripping tool.

Abstract: A multiple mode buckling beam probe assembly (50) is formed by top and bottom mating locating guides (70, 74) interposed between a space transformer die (52) bearing exposed wire contact ends (56) and an underlying substrate (58) having correspondingly positioned conductive pads (60). Wire probes (62) pass slidingly through aligned holes (72, 76) within the top (70) and bottom (74) mating locating guides. At least one center locating guide (82) having correspondingly aligned holes (84) with the top and bottom locating guides slidably receives the wire probes (62) and is spaced at different distances from the top and bottom locating guides. Interposed between the center locating guide and the top and bottom locating guides are respective slotted guides (86,90,94) having elongated slots (88,92,96) through which the wire probes pass, which slots are offset relative to the top, bottom and center locating guide holes (72, 76, 80). This permits an increase in axial deflections of the wire probes over a standard buckling beam probe, adequately confines the directionality of the buckling wire probes, achieves greater probe density, and permits the controlled sequence and magnitude of seach buckle in multiple mode buckling with the characteristic force versus deflection curve for the buckling wire probes being tailorable to a specific user's need.
