Abstract: SELF-CORRECTING MICROPROCESSOR CONTROL     SYSTEM AND METHOD FOR A FURNACE                 ABSTRACT OF THE DISCLOSURE            A self-correcting control system and method is provided for a furnace to correct certain operating conditions that exceed normal limits.  Upon sensing insufficient air flow as a function of the pressure drop across the heat exchangers, the control system and method cause the inducer motor to increase in speed, thereby to increase the flow of combustion air. Similarly, upon sensing that the flow of air to be heated exceeds a predetermined temperature, the control system and method will increase the speed of the air blower to increase the flow rate of air to be heated through the furnace, thereby resulting in lowering the temperature of the air to be heated below the predetermined temperature.  Upon sensing a gas flow leak through the gas regulator, the control system and method will recycle the gas regulator to properly seat a gas flow control valve therein.  If none of the self-correcting features correct the particular occurring problem, the control system and method will shut down the furnace.

Abstract: ABSTRACT     The invention comprises a thickening agent comprising an aqueous-soluble polymeri-zation product of one or more water-soluble mono-mers which are sufficiently water-soluble to form at least a 10 weight percent solution when dis-solved in water and which undergo addition polym-erization to form polymers which are water-solu-ble; and at least one second monomer of the for-mula:                         III     32,120-F     wherein R is a hydrocarbyl radical which contrib-utes hydrophobic character to the second monomer, Z is a divalent linking group, M is a divalent hydrocarbyl or substituted hydrocarbyl radical and Y is an ionic species which contributes hydro-philic character to the molecule.           These compositions are useful for thick-ening aqueous mediums, in particular, for thicken-ing aqueous media containing water-soluble elector-lytes.  Such thickened aqueous media retain their viscosity when subjected to shear, heat or high electrolyte concentrations.  The thickened aqueous solutions may be used in enhanced oil recovery pro-cesses as fluid mobility control agents, fracturing fluids and drilling muds, as well as hydraulic fluids and lubricants. 32,120-F

Abstract: Abstract of the Disclosure A modem system is disclosed which has  improved reli-ability  of  detection  of  transmitted PSK  data  using  a  simple signal delay detection scheme.  A transmission signal is produced in which repetitive digital time slots each contain phase encoded "mark"  or  "space"  data.   Each  time  slot includes  a  reference phase portion at at least one of a front and rear portion of the time slot.   The phase of the transmitted signal changes in the remaining portion of each time slot in accordance with applied digital data.  For a "mark" data signal the phase changes from a reference phase in a first direction to predetermined phase in a first half of the remaining portion of the time slot, and then back to the reference phase before the end of the time slot. For a "space" data signal the phase changes from the reference value in a second direction opposite the first to another predetermined value in a first half of the remaining portion of the time slot, and then back to the reference phase before the end of the time slot.   A simple delay detection demodulation system is used to recreate the original digital signal.

Abstract: A circuit for voltage multiplication has a capacitor which is connectible via first switching transistors to a supply voltage source and via further first switching transistors in series with the supply voltage source and with a storage capacitor which is connected in parallel to the circuit output. Clock voltages for driving the first switching transistors are switchable in amplitude from a value corresponding to the supply voltage to the value corresponding to the output voltage. In order to achieve high efficiency of the circuit, a clock voltage generator is controllable for amplitude switch over via a supply line which is connectible via a second switching transistor to the supply voltage source and is connectible via a third switching transistor to the circuit output, whereby these switching transistors are driven via the outputs of the comparator which compares the supply voltage to the output voltage. The circuit may advantageously be employed in hearing aid circuits.

Abstract: Recombinant transforming growth factor- beta 1 (TGF- beta 1) is expressed to high levels in Chinese hamster ovary (CHO) cells using dihydrofolate reductase (dhfr) gene amplification. The expression plasmid was derived from the pSV2 vectors and contained, in tandem, the simian TGF- beta 1 and mouse dhfr cDNAs. Transcription of both cDNAs was controlled by the SV40 early promoter. Stepwise selection of transfected CHO cells in increasing concentrations of methotrexate yielded cell lines expressing amplified TGF- beta 1 nucleic acid sequences. The expression plasmid DNA was amplified greater than 35-fold in one of the methotrexate selected transfectants. The major proteins secreted by these cells consisted of latent TGF- beta 1 and TGF- beta 1 precursor polypeptides as judged by immunoblots using site-specific anti-peptide antibodies derived from various regions of the TGF- beta 1 precursor. Levels of recombinant TGF- beta 1 protein secreted by these cells approached 30 ug/24 hour/10<7> cells. Expression vectors encoding TGF- beta 1 precursor variants which direct the synthesis and secretion of TGF- beta 1 in transfected mammalian cells are also described.
