Patent EP-0202216-A2 (EP)
Inventor: PLOHBERGER DIETHARD DIPL-ING
IPC: F02B25/16
Filed: 1986-04-28
Abstract: 1. A method of scavenging a two-stroke reverse-flow scavenged engine comprising a piston-controlled exhaust passage and two or more primary as well as secondary scavenge passages on either side of the said exhaust passage, through which the fresh charge is delivered to the cylinder by means of a crankcase pump, a flow being generated at the beginning of the scavenging process by the primary scavenge passages located on either side of the exhaust passage in the immediate vicinity of the latter, which will prevent the fresh charge from entering the exhaust passage, wherein during the downward stroke of the piston the intake ports of the two or more primary scavenge passages are uncovered at a time when the pressure in the cylinder still is higher than in the crankcase, inducing the exhaust gas to flow into said scavenge passages and to force back the fresh charge contained therein without entering the crankcase itself, and wherein upon a drop of the pressure in the cylinder below the pressure level in the crankcase a connection is established between the primary scavenge passages and the crankcase, the intake ports of the two or more secondary scavenge passages being uncovered at the same time, such that the cylinder is scavenged and filled with fresh charge, the exhaust gas admitted into the primary scavenge passages before being discharged again due to a reversal of pressures, forming a barrier against the escape of fresh charge through the exhaust port, upon which the fresh charge will be discharged through the said primary scavenge passages.

Abstract: A signal viewing instrumentation control system includes a programmable test instrument, a computer having an input keyboard and/or mouse, a CRT display and a communications interface for the computer to communicate with the test instrument. The test instrument can be a digitizer, a spectrum analyzer, a power supply or a signal generator. The system includes software for the user to interactively control the test instrument through the computer. The software includes a functional characterization of the test instrument for inversely transforming a generic output for the instrument into a generalized set of control setting commands for controlling operation of the instrument. The user can graphically enter into computer a user-specified output for the instrument. The computer converts the graphically-specified output into a specific set of the control setting commands and transmits the specific commands to the test instrument to control its operation. The user can thereby interactively control the test instrument to provide an output function replicating a desired output function without having to enter a control settings to the test instrument either manually or as program language control statements.

IPC: G06F13/28
Filed: 1988-06-01
Abstract: In a computer system, each of several peripheral devices communicates through an associated adapter with a controller. The controller sequentially establishes direct memory access data transfers between main memory on a system bus and individual peripheral devices. A sequencer establishes individual cycle times during which each adapter and an associated direct memory access controller is able to complete a DMA transfer. The adapter is conditioned for DMA and other data transfers by control signals from the controller. A demand signal is asserted by the adapter only when the buffer memory of the adapter is prepared to service the DMA transfer. The sequencer responds to the demand signal to generate a request for a DMA transfer during which a predetermined, limited amount of data is transferred in a DMA operation. During start-up, the adapter responds to initial control signals to provide an identifier to the controller so that the controller is able to fetch the software required to communicate with the adapter.

Abstract: In a hydraulic control device having at least one distributing valve (2m, 2') connected upstream of a consuming point (35), a more effective energy utilization is achieved by means of a pressure step (D) provided for the input pressure of a second throttling point (15), which can be switched in stroke-dependent fashion by means of a control element (17, 17') of the distributing valve (2, 2') so that the maximum difference in pressure between the pump line pressure P(4) and the consumer pressure P(3) is only controlled shortly before the need of a high conveying amount. Before this the difference in pressure is kept smaller.

Abstract: Disclosed is an electro-optical component package (12), arranged as a dual in-line pin (DIP) package, and a socket (13) therefor. Connector pins (17) extending from the package establish electrical and optical contact to the package with mating connector receptacles (19) of the socket. Each pin and receptacle has a metallic body (41,26) for establishing electrical connection between the pin and receptacle when the two are mated. Each body defines a passageway (42,27) through which extends an optical fiber (30,21). When the bodies of a pin and receptacle are mated, the optical fibers extending therethrough are optically coupled. The receptacle includes a cup member (39) that is positioned loosely and movably in its passageway. The cup member defines a passageway (37) by which it mounts around the end of the receptacle's fiber. When the pin and receptacle are mated, the cup member receives and mates the end portion (51) of the pin, thereby aligning the ends (57,46) of the receptacle's and pin's fibers. A coiled spring (36) positioned in the receptacle's passageway around the receptacle's fiber urges the cup member against the end portion of the pin.

Abstract: The upper parts of the cylinder liners and the cylinder head are formed integral in one piece, and a water jacket is provided around the outer peripheries of the upper parts of the cylinder liners, with no water jacket provided to the cylinder body. This eliminates the use of the core for the water jacket in molding the cylinder body, which in turn reduces the engine weight, brings about a significant cost reduction and makes machining operations easy. Because the piston head is made of a heat insulating material and a water jacket is not provided to the cylinder body, the heat is prevented from flowing down to the cylinder liners. Furthermore, the cylinder liners are made of a ceramic material to improve an anti-galling characteristic during sliding motions at high temperatures. Also, since the water jacket is provided only to the cylinder head, the water jacket can be made simple and small in structure, reducing the cooling water flow resistance. This in turn permits the use of a small motor-powered water pump that can be controlled independently of the engine conditions. Moreover, since the cylinder body has no water jacket, there is a greater freedom in designing the cylinder body, which makes it possible to form reinforcement ribs   on the cylinder body to increase its rigidity and thereby reduce vibrations and noise.
