Abstract: METHOD FOR PACKAGING A MICROWAVE TUBE MODULATOR                         ABSTRACT           A method for packaging components in the primary circuit of a microwave tube modulator output transformer. Modules are assembled using parallel plates upon and around which transistors and other necessary components are mounted.  In addition to providing mechanical support for the components,  the plates act as conductors for circuits  common to respective elements of paralleled transistors, thereby minimizing electrical resistance and inductance in the primary circuit.   The modules are designed to mount to the output transformer such that two of the parallel plates are mechanically connected to the respective two ends of the transformer primary, and a number of modules can be mounted around and to one transformer according to the amount of energy required.

Abstract: RING BALANCER                Abstract of the Disclosure A dynamic  ring  balancer  for  a  machine  shaft, including an annular case fixedly attachable to the shaft with a central  aperture sized  to  receive  the shaft  therethrough. The  case  has  an  annular  chamber  extending  about  the  case aperture  and  containing  a  part  if  eccentrically  weighted balancing rings rotatably mounted within the annular chamber. The rings are rotatable relative to each other and the case.  A pair of turbine wheels are mounted at an outer wall of the case and  are  each  selectively  rotatable  in  both  rotational directions in response to engagement by pressurized air flows. The  air  flows  for  each wheel  are  selectively  applied  by  a stationary manifold as the wheels pass by the manifold while revolving with the case.   A pair of reduction gear assemblies are mounted within the case and each drivable interconnects one of the wheels and the corresponding ring to convert rotation of the  wheel  into  rotation  of  the  ring.    Through  selective rotation  of  the wheels,  the  rings  are  progressively  and independently rotated until the shaft is dynamically balanced. Thereafter, the reduction gear assemblies hold the rings locked in position until further adjustment of the rings is desired. In  an  alternative  embodiment  friction  engagement  wheels  are used.

Abstract: Process for the manufacture of sodium hydroxide in a sustained manner, tolerant of upsets in sodium hydroxide concentration, by electrolysis of sodium chloride at about 70-110°C in an electrolysis cell separated into a cathode compartment and an anode compartment by a cation exchange membrane, wherein the membrane is made of a copolymer of tetrafluoroethylene with a perfluoro monomer Z having a defined structure and a carboxyl end group, the mole ratio of tetrafluroethylene to the monomer Z in the copolymer being about 7.6 to 8.2, the membrane material on the side exposed to the catholyte being nonporous but having a porous catholyte diffusion layer in direct contact therewith or in close proximity thereof. The sodium chloride feed solution is about equal to the concentration of saturated brine at the operating temperature, and the concentration of sodium chloride solution leaving the anode compartment is about 18-24%, no water being added to the catholyte during steady state operation. In this manner, 42-54% sodium hydroxide can be made with current efficiencies of about 90-97%.
