Abstract: METHOD AND SYSTEM FOR SYNCHRONIZING A TDMA COMMUNICATION NETWORK COMPRISING A SATELLITE       EQUIPPED WITH SEVERAL DIRECTIONAL BEAM ANTENNAS TRANSMITTING SIGNALS       AT VARIOUS FREQUENCIES                      Abstract A method and a system are disclosed for synchronizing within a recurrent time frame the starting points of the transmissions from the various stations in a TDMA network wherein N stations distributed among M separate zones covered by M different down-link frequencies exchange pulse bursts through a satellite, each pulse burst being comprised of a preamble, a unique word, the transmitting station's address, and traffic data.  The satellite includes a global beam antenna which covers all of the M zones and is adapted to receive M different up-link frequencies, means for converting these M up-link frequencies to M corresponding down-link frequencies, and M directional beam antennas covering the M zones, each of said M antennas being adapted to transmit the down-link frequency associated with the particular zone it covers.  The bursts transmitted by the various stations are assigned a predetermined position within the frame.  Each station detects whether it has received a unique word followed by the address of a given station.  Upon detecting such an address, the station activates timing means which define a time interval associated with the station whose address has been detected and, at the end of that time interval, starts transmitting M successive bursts respectively destined for the M zones during predetermined time intervals within the frame. These M bursts are transmitted at different up-link frequencies so that the burst intended for a given zone will be transmitted at the up-link frequency corresponding to the down-link frequency for that zone.  In accordance with an embodiment of the invention, the timing means comprise M timers respectively defining N time intervals associated with the N stations.  The start of a station's transmission is determined by the timer which reaches its stopping point first.

Abstract: "GOLF BALL DISPENSER"          ABSTRACT OF THE DISCLOSURE           A trough is pivotally mounted to a central standard and can rotate through approximately 90° from a rest position to a ball dispensing position above a golf ball tee.  The trough, which holds golf balls and may be  replenished from a hopper, includes a dispensing head at the outboard end, which is constructed to allow passage of a golf ball therethrough.         The head is pivotally attached to the outboard end and can be moved from a ball detent position to a ball release position and vice versa, with the head normally being urged to the detent position by means of a small weight.  When the head is tipped forwardly to the dispensing position, a detent clears the front ball of the chute or trough which then moves forward-ly by gravity so that it is held temporarily between the front of the head and the rear of the aperture through which it will pass.  As the head is tipped rearwardly, the detent engages behind the front ball and checks the forward movement of the next ball and at the same time, widens the gap between the front of the head and the rear of aperture thus releasing the ball which is deposited upon the tee.

Abstract: Case 2572 PERMANENT MAGNET ALTERNATOR WITH CLAW TYPE ROTOR   AND MEANS TO ADJUST THE EXCITATION MODULE   ABSTRACT OF THE DISCLOSURE A dynamoelectric machine and, particularly an alternator, has a claw type rotor in which the magnetic field is induced by permanent magnets.  The claw type rotor has a spider of magnetic material secured to the rotor shaft and having a first set of claws on the periphery.  An annular disc of magnetic material is mounted to said spider and is spaced axially from said spider by a non-magnetic ring.  A second set of claws is on the periphery of the annular disc and these are interleaved with the first set of claws.  An excitation module is mounted within the casing of the machine and this module has one surface facing the spider and another facing the annular disc.  The permanent magnets are mounted on one of these surfaces, preferably on the surface facing the disc.  The magnets thus provide flux across the air gap to the spider to induce poles of one polarity in the first set of claws, and across the air gap to the disc to induce poles of the other polarity in the second set of claws.  A straight axial movement of the excitation module will adjust the air gap at the permanet magnets.  A screw arrangement is provided to move the excitation module axially to reduce the attractive forces due to the permanent magnets to aid in assembly and disassembly. Also, a field winding may be provided on the excitation module to control the flux at the poles during running, and to reduce the attractive force caused by the permanent magnets to aid in assembly and disassembly.

Abstract: ABSTRACT     Method of Converting Liquid and/or Solid Fuel to a Substantially Inerts-Free Gas The invention relates to the conversion of fuel (solid and/or liquid) to reducing and/or synthesis gas by contacting the fuel in a fluidized conversion bed (13) with a solid oxygen donor (e.g. CaSO4) at a fuel conversion temperature (e.g. 850 to 1150°C) in the presence of at least one gas/vapour phase substance such as H2 and/or H2O and/or CO and/or CO2 which serves to promote and or mediate the transfer of oxygen from the donor to the fuel and preferably in the absence of non-reactive gases (e.g. N2) whereby the fuel is converted to a reducing and/or synthesis gas product by (inter alia) partial oxidation employing the oxygen of the solid oxygen donor, the latter being reduced (e.g. CaS).  The reduced donor is exothermically oxidized in a fluidized oxidation bed (35) by contact with an oxygen-containing gas-((e.g. air) and re-used for converting further quantities of fuel.  Moieties (e.g. sulfur/sulfur compounds) whose presence is undesirable in the gas product may be removed by a solid moiety-fixing agent (e.g. CaO) in the conversion bed (13).  The moiety-fixing properties of the latter are at least partly regenerated in a fluidized regenerator bed (48) by treatment in a suitable regenerat-ing atmosphere, and the regenerated moiety-fixing agent is returned to the conversion bed (13) directly and/or indirectly via the oxidation bed (35).
