Abstract: ABSTRACT           A millimeter wave sensing device is disclosed comprising a local oscillator source generating a millimeter wave signal which is mixed with millimeter wave radiation reflected from or emitted by objects in a field of view.  The mixing is performed in a staring array of mixer/detector elements which need not be mechanically or electronically scanned to generate signals responsive to the entire field of view.  In a first embodiment of the invention, the device detects millimeter wave radiation emitted by or reflected from the object to be imaged.  In a second embodiment of the invention, the oscillator used to provide the local oscillator signal is also used to illuminate the field of view.  In the second embodiment of the invention, the oscillator signal is preferably linearly polarized, and a polarizing grid is used to separate the local oscillator signal and illumination beam and direct them in a simple and efficient manner.  A twist reflector may also be used to rotate the polarization of a portion of the beam to direct it onto the mixer/detector array for mixing with the received signal from the field of view.  Improved constructions of millimeter wave source and mixer/detector elements are also disclosed, which greatly simplify construction of the device.

Abstract: Present day diesel engines having aluminum piston assemblies are limited to combustion chamber pressures of approximately 12,410 kPa (1,800 psi) whereas the desire is to increase such pressures up to the 15,170 kPa (2,200 psi) range. To reach such levels the instant piston assembly includes a steel piston member having an upper cylindrical portion of a diameter "D" and a compression height "CH".   The ratio of the compression height "CH" to the diameter "D" being within the range of from 60% to 45%  The piston member is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly is preferably of the articulated type and includes a forged aluminum piston skirt connected to the piston member through a common wrist pin.  Engine manufacturers are also demanding a smaller engine package size while retaining power output, improve fuel consumption and decreased emissions.  The subject piston member provides a simple and inexpensive solution to the increased power output package size relationship.  To insure a small engine package, the piston member has a compression height to maximum diameter ratio within the range of from 60% to 45%.  The piston member is preferably made from a steel forging to insure a reduced porosity over that of existing standard castings.

Abstract: A purification process for waste water and/or waste water sludge, comprising a methane fermentation and subsequent oxidation of the reduced compounds present in the effluent of the methane fermentation by means of aeration, whereby the sulphide from the effluent of the methane fermentation is used as electron donor by the denitrification and whereby the residual reduced compounds from the liquid effluent from the methane fermentation not until the subsequent next step are oxidized by aeration. 
<??>In this way the suiphldes, produced by the methane fermentation, are used in appropriate way and simultaneously converted in non troublesome or innocent sulphate. 
<??>In the liquid effluent, remaining after denitrification, the ammonia, which was occurring in the effluent is still present; this ammonia is subsequently oxidized into nitrate at the aeration, whereby the sulphide cannot interfere with, as this sulphide was converted in sulphate with the denitrification. As no sulphide is more present, the aeration is demanding less air and aeration may moreover be more simple. 
<??>The hydrogen suiphide from the gas formed by the methane fermentation also may be used for this purpose, giving in this way the greatest utility of the products formed with the methane fermentation, while the gas is purified in a simple way.

Abstract: A communication system is described comprising different buses (20, 46, 56) which are interconnected via one or more gate connecting elements (20, 50). There is a transmitter station transmitting a frame that comprises a target address field and one or more destination address fields. If the send and receiver stations (46, 48, 52, 54) are connected to the same bus, the contents of the target address field are sufficient to define the receiver station. In other cases the target address field defines a gate connecting element, whereas the latter fills the the target address field with the contents of one of the other fields. In this way receiver station addresses, which have already been defined on a previous bus, can again be used on the next bus. Furthermore, in a short-frame format, receiver stations on the same bus as the transmitter station can be addressed with very low overhead.
