IPC: H03D7/16
Filed: 1984-05-07
Granted: 1986-10-22
Abstract: Mixer arrangement (M) comprising first and second quadrature mixer stages (M, resp. M<sub>2</sub>) to which quadrature mixing signals are applied from an oscillator circuit (Fo), these two mixer stages (M, and M<sub>2</sub>) being coupled to a superposition circuit (So). To suppress interferences occurring in the output signal of the superposition circuit due to oscillator crosstalk or leakage and/or a d.c. offset of the mixer stages (M, and M<sub>2</sub>) which are supplied with mixing signals by the oscillator circuit Fa, the quadrature components of these interferences being in phase with the quadrature mixing signals are measured by means of first and second synchronous detectors (SD<sub>1</sub> resp. SD<sub>2</sub>) to which detection carriers are applied in an in-phase or an anti-phase relationship with respect to the quadrature mixing signals. After sign inversion these quadrature components are fed back to the inputs of the two mixer stages (M, and M<sub>2</sub>), resulting in an interference negative feedback.

Abstract: A well coring apparatus (10) includes an outer barrel (12) and an inner barrel (18). The inner barrel (18) is sealed at one end with a sealing member (80) and has a reciprocating piston (70) disposed in the other end thereof. On O-ring (68) is disposed at the receiving end of the inner barrel (18) to provide a seal therefor. Spring members (76) provide a restrictive force to the piston (70). A sponge (50) is disposed around the inner walls of the inner barrel (18) for contacting the core (82). A fluid is disposed in the inner space (78) of the inner barrel (18) and pressurized. Reciprocation upward of the piston (70) causes the fluid to flow therefrom out the receiving end of the inner barrel (18). This flow of fluid washes the sides of the core (82) to prevent drilling mud from caking about the surface thereof and preventing proper transfer of fluids contained within the core (82) to the sponge (50). The fluid in the inner space (70) has a density that is lower than that for fluids external to the inner barrel (18) such that contamination of the sponge (50) is prevented.

Abstract: An electronic odometer (10) which is field presettable within limits after it is installed in a vehicle. A microprocessor (14) is utilized to store a total accumulated mileage (odometer) signal in a non-volatile random access memory (RAM) (19). The microprocessor retrieves stored odometer signals, loads them into a microprocessor contained volatile memory (14a), increments the volatile memory odometer signal in accordance with signals from an actual mileage sensor (11) and displays the odometer signal on display (24). The magnitude of the odometer signal stored in memory (19) can be preset to a predetermined mileage after the non-volatile memory is coupled to microprocessor (14). This presenting can only be implemented a maximum of three times and only if 10 driven mileage storage location (22) in non-volatile memory (19) indicates that the vehicle in which the odometer is installed has been driven less than ten miles. Wherein the signals in ten driven mile storage location (22) cannot be preset. In response to a substantial (more than ten mile) adjustment of the odometer signal stored in the non-volatile memory (19), an overflow flag is non-volatilely stored and this results in the odometer display providing a visual indication (at 26) that a substantial adjustment of the odometer signal in the non-volatile memory (19) has occurred. The presetting of the odometer signal in non-volatile RAM (19) is accomplished through utilization of the trip and units manual controls (15-17), and the vehicle ignition switch (12).

Abstract: The invention relates to an inhalation apparatus with a compressed air generator (9), an electromotor (10), which drives the latter and supports a fan wheel (11), and a housing (1) surrounding these. The housing (1) is made up of a housing top part (2), a housing bottom part (3) and a front plate (4) inserted between these. Provided on the rear side (12) are air inlet slots (13, 14) through which cool air is drawn in by the fan wheel (11) into the inside of the housing (1). An angled front plate portion (17) of the front plate (4) and a correspondingly angled front portion (18) of the housing top part (2) together form an air outlet channel (19), whose outlet gap (20) is directed obliquely downwards. Provided in the housing bottom part (3), in the front portion of the housing base (15), are air outlet slots (21), which likewise are directed obliquely forwards. A cross-piece (22) on the housing base (15) prevents a return flow of expelled cool air. All the cool air, conveyed through the inside of the apparatus, flows in an upper and a lower partial current past the compressed air generator (9) and the electromotor (10) and is expelled obliquely downwards in the area of the front side (16). The position and especially the design of the air outlet channel (19) and of the air outlet slots (21) result in a considerable reduction in the operating noises of the compressed air generator (9) and the electromotor (10) escaping from the housing (1), without the stream of cool air being significantly impeded. The cool air expelled in the area of the front side (16) is kept away from the patient. In addition, the front side (16) of the inhalation apparatus according to the invention remains free from soiling. <IMAGE>

Abstract: The invention relates to a spark-ignition internal combustion engine having a combustion chamber which, at least in part, presents surface areas (10) which have been treated to reduce the octane number requirement of the engine. 
<??>The surface area to be treated may, for example, be either blasted or etched to produce surface depressions, and is then flame sprayed with copper particles to form heat-reflective surfaces. At least this latter method results in solely low-temperature heating of the walls of the combustion chamber, which can be advantageous in the case of diesel engines, but not in the case of Otto-cycle engines. 
<??>The improvement in such engines afforded by the invention is that the surface areas (10) are instead provided with at least one layer (12) which presents to the combustion chamber (1) a defining surface (9) which exhibits an extremely low reflectivity to electromagnetic waves in the wavelength range of about 0.2-7.0 microns, and which also results in diffuse reflection of non-absorbed incident waves (14).
