Filed: 1993-05-06
Abstract: VARIABLE SPEED DRIVE SYSTEM Abstract of the Disclosure A variable speed drive system for use with a self-propelled device is coupled by a belt to an engine which is mounted to the device.  The variable speed drive system includes a variable pitch pulley held in spaced-apart relation to the drive shaft by a fixture and rotates about the drive shaft between a first position proximal to the engine and a second position distal to the engine.  In the first position, the drive system is disengaged from the engine and the speed of the self-propelled device is zero, the belt being slack and providing no drive force to the drive system.  In the second position, the drive system is moved a maximum amount about the drive shaft and is positioned to achieve a maximum speed.  The drive system can also assume any intermediate position between the first and second positions, with the speed of the self-propelled device being determined by the amount of movement about the drive shaft toward the second position.  A speed control lever and a control cable assembly are included for limiting the amount of movement of the drive system about the drive shaft to control the speed of the self-propelled device.

Title: Treating rhodium, iridium and ruthenium solutions
Inventor: BRUENING RONALD L
IPC: C01G55/00
Filed: 1992-06-02
Abstract: A method for the removal, separation, and concentration of Rh, Ir, and/or Ru from a source solution which may contain larger concentrations of other ions including H+ comprises bringing the source solution into contact with a compound comprising a polyalkylene-polyamine-containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The ligand portion(s) of the compound has affinity for complexed anionic species of Rh, Ir, and/or Ru. The Rh and/or Ru are first selectively removed from the compound through contact with a much smaller volume of a first receiving solution. The Ir is then removed from the compound through contact with a much smaller volume of a second receiving solution having a greater affinity for the Ir than the liquid portion of the compound or having a greater affinity for the ligand portion of the compound than the Ir species. The process is useful in the recovery and refining of the valuable Rh and Ir from a variety of sources. The invention is also drawn to the particular highly stable branched polyalkylene-polyamine-containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Patent CA-2104755-A1 (CA)
Inventor: PAWELSKI ROBERT L
IPC: H04Q11/04
Filed: 1993-08-24
Abstract: A time-division multiplex switch (100) switches a hierarchy of data rates. It sets up higher-rate connections not as a plurality of individual lowest-rate connections but as one or more time slots in each one of a plurality of sequential frames (40, 50) that correspond to that higher rate in each superframe (30). A time-slot-interchange switching element (131, 141) of the switch utilizes a plurality of physically or logically distinct double-buffered data memories (301,302, 303) each corresponding to a different one of the superframe and different-size ones of the frames. Reading and writing of each of the data memories' buffers alternates with the corresponding one of the superframe and different-size frames; reading of a data memory's buffer immediately follows writing of that buffer. Information from all incoming time slots is written into each one of the data memories, but only information corresponding to the data rate of an individual data memory's corresponding frame size is read from that data memory into outgoing time slots. A control memory (305) maps memory locations of the data memories to output time slots. A corresponding control architecture in a switching element (1700) of a time-multiplexed switch (120) uses a control memory (1701) that maps input ports to time slots of an output port. <IMAGE>
