  • Patent number: 4852525
    Abstract: According to the present invention, main and subcombustion chambers into which fuel is fed directly in an atomized state and in each of which a swirl is formed, are formed in communication with each other in a top portion of a piston, in order to use not only gas oil but also other volatile fuels of low cetane number such as gasoline and alcohol. Further, in order to improve the combustion performance, fuel is supplied into the subcombustion chamber in a finely pulverized state for easier evaporation, and fuel is adhered as liquid films to the main and subcombustion chambers. By so doing, ignition is ensured in all load conditions and it becomes possible to effect evaporation and combustion on the wall surface of each combustion chamber. Consequently, it is possible to obtain a combustion performance which is low in combustion noise and vibration and also low in the formation of unburnt matter.

  • Patent number: 4836784
    Abstract: The invention relates to a device for displaying information on a reading unit for the blind. Instead of character fields arranged with certain spacings apart from one another for displaying Braille characters, the reading table is occupied by a dense matrix of character elements (4) with uniform line and column spacings. In the totality of character elements, certain character fields (6) are provided which serve for displaying the Braille characters. These are surrounded by other character elements which are not set in the displaying of Braille text, so that the Braille characters have the required spacing apart from one another. The whole reserve of character elements (4) is used for reproducing large-area graphics, large symbols, tables or the like. With a certain arrangement, described in detail, of the character elements, all of the information displayable on a viewing screen can be reproduced on the reading table, with the exception of reverse-brightness information and that displayed in colors.

  • Patent number: 4831698
    Abstract: A method of attaching a female element having an annular riveting portion to a panel and the installation apparatus. The method includes driving a punch through the female element into a panel supported on a die member forming an unsupported cone-shaped panel portion in the cavity of the die member. The punch includes an axially extending piercing end which pierces a small opening in the cone-shaped panel portion and an arcuate drawing portion which is driven against and through the panel opening, enlarging the panel opening. The annular riveting portion of the female element is then driven into the cone-shaped panel portion and through the panel opening, drawing the panel portion into a tubular shape engaging the external surface of the riveting portion. Finally, the riveting portion is driven against a center post of the die member, radially outwardly deforming the free end of the riveting portion and forming a mechanical interlock with the tubular panel portion.

  • Patent number: 4829420
    Abstract: A process and a circuit arrangement for the automatic direct addressing of any desired memory location in the memories of a plurality of data processing units interconnected through a common bus by use of a single-step addressing technique is disclosed. The size of the memories used in the various processing units may be different. Addresses may be internally stored in the memories according to one of two addressing schemes. In a data processing unit initiating a data transmission connection, the external memory address of the desired memory location to be addressed is generated from an internally stored address and is transmitted to the bus system. This external address is received in each data processing unit, which performs an address calculation to determine whether the specified external address is within its volume or range of addresses.

  • Patent number: 4822394
    Abstract: The present invention provides a method and apparatus for collecting and liquefying off-gases, particularly carbon dioxide, generated by a wet oxidation of organic matter and for the on sight gasification of liquid oxygen for use as an oxidant in the wet oxidation reaction. Through a series of separation and pressurization operations, high pressure off-gases are introduced into a heat exchanger at substantially the same time as liquid oxygen. The liquid oxygen and compressed off-gases are in heat exchange relation in the heat exchanger but are isolated from one another. Heat is transferred from the compressed off-gases to the liquid oxygen whereby the off-gases are liquified and the liquid oxygen is gasified. The liquified off-gases may then be stored in appropriate storage units. The gaseous oxygen is used as the oxidant for the wet oxidation reaction.

  • Patent number: 4818697
    Abstract: A method is provided for enhancing the transport of a selected ion having a predetermined charge-to-mass ratio through a biomolecular membrane located in a space subjected to a local magnetic field. The space defines at least one reference path passing through the membrane in opposite first and second directions. The method includes the steps of creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending in the first direction along the path. This component of the magnetic field has a magnitude that fluctuates at a predetermined rate to produce a nonzero average value. A predetermined relationship between the ratio of the selected rate to the nonzero average value and the charge-to-mass ratio of the predetermined ion is thereby created. The predetermined relationship, is a function of the cyclotron resonance frequency of the ion.

  • Patent number: 4817752
    Abstract: The device for disconnecting the wheels from a vehicle's optional drive is mounted inside the support of the axle shaft, and the wheel hub is splined onto the axle shaft. The universal joint is diametrically positioned in relation to the support of the axle shaft by a bearing. The universal joint has an internal splined section which corresponds to an internal splined section on the clutch disc for "engage" and "disengage" positions. A fluid responsive actuating device is provided including a movable member in the form of a diaphragm or a piston connected to the clutch disc for axially moving, in response to the pressure or pressure differential from a fluid source to effect the engagement and disengagement of the clutch disc splines in relation to the axle shaft and universal joint splines.

  • Patent number: 4815472
    Abstract: A capacitive pressure sensor suitable for making highly sensitive, low pressure measurements is disclosed. The sensor may be mounted into a 0.5 mm OD catheter suitable for multipoint pressure measurements from within the coronary artery of the heart. The sensor employs a transducer which consists of a rectangular bulk silicon micro-diaphragm several hundred microns on a side by two microns thick, surrounded by a supporting bulk silicon rim about 12 microns thick. Both the diaphragm and the rim are defined by a double diffusion etch-stop technique. The transducer fabrication process features a batch wafer-to-glass electrostatic seal followed by a silicon etch, which eliminates handling of individual small diaphragm structures until die separation and final packaging. An addressable read-out interface circuit may be used with the sensor to provide a high-level output signal, and allows the sensor to be compatible for use on a multisite catheter having only two electrical leads.

  • Patent number: 4813819
    Abstract: An annular hole cutter wherein each tooth is formed with a radially outer cutting edge and at least alternate teeth are formed with radially extending, circumferentially staggered inner and outer cutting edges. The bottom face of each tooth is formed with oppositely radially inclined inner and outer back-off faces which intersect in a downwardly extending crest which in turn intersects the radially outer cutting edge. The outer back-off faces of alternate teeth are vertically relieved relative to the outer back-off faces of the intermediate teeth and the inner back-off faces of the intermediate teeth are vertically relieved relative to the inner back-off faces of the alternate teeth a distance greater than the chip load at which the cutter is operated. In the preferred form, the radially inner portion only of the unrelieved inner back-off face is relieved to a greater extent than the relieved inner back-off faces.
