Abstract: ABSTRACT OF THE DISCLOSURE            The ingestion of air into the print head of an ink jet printer is controlled by a secondary fluidic system.  The secondary fluidic system interconnects the ink supply cavity of the head with the primary fluidic system of the printer.  The secondary fluidic system includes a valve which is coupled to a venting port of the print head.  A rapid decompression regulator is coupled to the valve.  The exit port of the regulator is attached to one end of a conduit. The other end of the conduit is disposed in a fluid-containing reservoir.  The reservoir serves as an expansion/contraction chamber and keeps air from entering the head even under extreme thermocycling conditions.  Likewise, the regulator controls the pressure in the head so that head pressure (Ph) is greater than or equal to ambient pressure Pa.  This pressure differential prevents air from entering the head.

Abstract: DATA PROCESSING SYSTEM BUS FOR  MULTIPLE INDEPENDENT USERS                          ABSTRACT            A new bus permits processing elements (PE's) to communicate with other PE's entirely under the control of each PE without a separate bus controller. Each PE has means for broadcasting its priority code on a contention portion of the bus and for sampling the bus after a delay in which it has received the codes from other PE's.  Each PE holds its priority code on the bus for a further delay during which other PE's can sample the priority code.  The PE's resolve contention for access to the information portion of the bus in a multi stage contention sequence.  System usage, made possible by peer-to-peer distribution of bus access control, includes dynamic driven priority schemes, a variety of operating modes and hence flexible multiplexing of message traffic.

Abstract: ABSTRACT.         Golf clubs for an individual golfer are provided as a matched set wherein the vibration frequency of the irons are set to a first predetermined common frequency, and that of the woods to  a second predetermined common frequency.  The preferred swing vibration frequency comprises the natural vibration frequency of a club when the shaft is secured at the normal grip position, so as to simulate the natural vibration mode of the club when being swung by the golfer. In the case of the irons, the preferred frequency normally lies in the range of 280 to 325 cycles per minute (CPM), and in the case of the woods the selected swing vibration frequency normally lies in the range of 250-280 CPM.  The determination of the ideal swing vibration frequency for an individual is usually done on a trial basis using a number of club sets wherein each set is matched but unmarked, and selection is made on the basis of personal preference.  Alternatively, using the particular club from the players bag for which a strong preferences is expressed, the swing vibration frequency thereof is measured, and the other clubs frequency balanced thereto, for the irons and for the woods, the frequency for the irons being held to an accuracy of about 2 cycles per minute, similarly for the woods.

Abstract: ABSTRACT OF THE DISCLOSURE          Decoding or demodulating circuitry can produce stereo right channel and left channel signals from AM stereo signals that have been coded according to any of the well known methods.  A stereo sum signal made up of the left and right channel stereo signals added together, and a stereo difference signal made up of the difference between the stereo left and right channel signals are developed and fed to a matrix to interconnect these signals to extract or separate the left and right channel stereo signals.  At least one of the known methods of Stereo coding requires phase shifting of these two developed signals and suitable phase shift circuitry, along with a switching circuit provides the matrix with the appropriate signals when that method of stereo coding is employed at the broadcast side.  The stereo sum signal is developed using envelope detection and the stereo difference signal is developed using synchronous detection, with the synchronous detector employing signals developed in the envelope detection process.          When the stereo broadcasting wave belongs to the other coding systems, the stereo sum and difference signals are respectively supplied directly to the matrix circuit through the switches.

Abstract: ABSTRACT A wet separator for purifying polluted conditioning air and separative solid and semi-liquid particles, especially paint particles in the outlet of a spray painting booth (1). For this purpose, there is a series of outlets (46 and 47) with surfaces converging in the direction of flow and finally a neck (38) or throat (45) which is intended to increase the speed of passing media by throttling and thus achieve mixing of air, water and pollutants. According to the invention, beyond the first outlet (46) in the direction of flow there is a dispersing chamber (40) for further mixing and atomizing the mixture, which chamber terminates in the direction of flow in the second outlet (47), which is designed as a venturi with a more extensively throttled venturi opening (45) defined by a flange (42) extending into said opening. The outlets may be interconnected by a guiding surface (35), on which a dispersing stream (48) of water droplets, air and pollutions impinge with flat angle of impact adjacent to the outlet at the end of the guiding surface. The impact area provides a special disintegration zone in front of the second outlet serving as a sound absorbing cover (Fig. 2). Alternatively intermediate outlets may cause tortuous flow through the dispersing chamber (40, 40') providing an extended path which retards transmission of noise from the final outlet (47) back to the booth (Fig. 6).
