Title: Production of supported thin film membranes
Inventor: FEIMER JOSEPH L
IPC: B01D67/00
Filed: 1991-06-20
Abstract: ABSTRACT OF THE DISCLOSURE           Supported thin  film  membranes  of  polyure-thane, polyurea/urethane,  polyurea/polyurethane  alloy blends are  prepared by  depositing a  solution of  the appropriate  polymer  on   a  microporous   hydrophobic support.  The solution wets  but does not soak  through the hydrophobic support because the amounts and  ratios of solvents and surfactant used to produce the solution have been adjusted to produce a solution having optimum coating  properties  (for  example,  surface   tension, solvency, viscosity).  The polymer solution is  option-ally aged at least 1 day  prior to being coated on  the microporous support.

Title: Epoxy/polyolefin coating process
Inventor: COX JAMES J W
IPC: B05D1/36
Filed: 1990-04-06
Abstract: ABSTRACT OF THE DISCLOSURE          A method of coating metallic pipe is disclosed. The method comprises heating the pipe to a temperature of at least 200°C and applying an epoxy resin composition having a thickness of at least 300 microns to the outer surface of the heated pipe.  Before the epoxy resin composition has completely cured, but preferably after it has gelled, a coating of a modified polyolefin is applied in a thickness of at least 300 microns.  The modified polyolefin is a homopolymer of copolymer of hydrocarbon alpha-olefins having 2-10 carbon atoms that has been modified by grafting with ethylenically unsaturated organic carboxylic acid or anhydride.  The resultant coating is resistant to impact damage and cathodic disbondment.  The coated pipe may be used in buried pipelines in the petroleum industry.

Abstract: In  a switching regulator, input  voltage  is applied  to a primary coil of a transformer  through  a location  between  a  collector and  an emitter  of  a switching transistor connected in series to the primary coil  of the transformer.  A pair of  output  terminals are  connected to a secondary coil of  the  transformer through  a rectifier smoothing circuit.   A  comparator compares  output voltage occurring between  the  output terminals with reference voltage to generate an  output signal.   On the basis of the output signal, a  control circuit applies a drive control signal to a base of the switching  transistor.  The reference voltage is  given such   that  first  voltage  maintained  substantially constant  and  second  voltage such  as  outside  input voltage or the like capable of being regulated over  a relatively large varying width are added to each other.
