Abstract: ABSTRACT OF THE DISCLOSURE     A hair treatment composition for heat waving comprising at least one compound selected from the group consisting of an amino acid free of a mercapto group, peptide, protein, and derivatives thereof.  With a composition according to the invention, hair can be firmly waved by a simple operation under a relatively low temperature and in a short time.  Since the composition does not include either alkaline solutions of high concentrations or reducing agents such as mercapto compounds, the damage to hair caused by elution of hair proteins can be mitigated.

Abstract: ABSTRACT OF THE DISCLOSURE           A heat cooking apparatus with a temperature operating system, wherein a microcomputer detects an abnormality of a temperature sensor and de-energizes the cooking apparatus to stop cooking while also producing a sensor fault pulse signal.  Upon counting of a prede-termined number of sensor fault pulse signals in a count-er, the microcomputer generates a sensor defect signal to alert the user of the defective temperature sensor. Spurious fault conditions are ignored by resetting the counter upon proper operation of the sensor before reach-ing the predetermined number of sensor fault pulse sig-nals.

Abstract: ABSTRACT           A  system  for  the  control  of the  air-fuel ratio in an internal combustion engine incorporates an electronic control unit, a sensor of exhaust emissions and a valve for metering fuel with air to control the air-fuel ratio.   The electronic control unit provides for the comparision of the successive measurements of the sensor output voltage under conditions wherein the fuel  valve  is  being  operated  for  ever  increasing richness or leaness until such time as the differential measurement  drops  below a  predetermined amount.   An offset voltage is then subtracted from or added to this voltage to calculate an operating set point voltage.          Thereby,  the system's accuracy  is maintained through the  compensation  for  changed  sensor  characteristics with aging.

Abstract: MULTI-FUNCTION VALVE                       Abstract A multi-function valve usable in a hydro-static transmission and having valve components mounted in a single valve body to provide pressure limiter and high pressure relief functions and with the structure also providing a bypass function and for supply of make-up fluid to the hydrostatic transmission. The multi-function valve has a charge check valve member and a relief valve member in associated relation and moveable upon the occurrence of a predetermined pressure dif-ferential thereacross to perform control functions. One pressure differential results from a flow through an orifice and with the flow being controlled by a poppet valve member normally held closed by a heavy spring which establishes a system pressure at which the pressure limiter function will occur. With this structure, the pressure: limiter function occurs in advance of the high pressure relief function and under the control of a single heavy spring.  With two of the multi-function valves utilized with the hydrosratic transmission, various con-trols are operable with flow in either direction to the motor through pressure lines between the pump and motor defining  a closed loop circuit.

Abstract: Abstract A method of controlling temperature during a pyrolysis reaction wherein the predominant pyrolysis reactions are endothermic.  A fuel and oxidizer are combusted in a combustion zone to produce a hot gas stream at a superatmospheric pressure.  The hot gas stream is then passed through a converging-diverging nozzle to accelerate the hot gas stream to a velocity of at least about mach 2,  The reactant to be pyrolyzed is injected into the supersonic hot gas stream to produce a reaction mixture flowing at supersonic velocity and initiate the endothermic pyrolysis reactions.  Substantially immediately thereafter the velocity of the reaction mixture is reduced over a predetermined reaction time to convert the kinetic energy of the reaction mixture to thermal energy in an amount sufficient to substantially offset the endothermic reactions taking place while maintaining supersonic flow.  At the end of the predetermined reaction time the velocity of the reaction mixture is reduced to subsonic flow and the reaction quenched.  The present invention is particularly adapted to the pyrolysis of methane to produce acetylene and ethylene by contacting the methane with hot gases resulting from the reaction of hydrogen with oxygen.

Abstract: ABSTRACT OF THE DISCLOSURE         Wire for repairing or changing circuit elements such as printed circuits has heat-resistant insulation surrounded by a hot-melt adhesive.  The wire is attached to the surfaces of printed circuit boards easily by applying a hot iron to the adhesive layer on the wire and melting the adhesive which then adheres to the board surface.  The hot iron has a tip with a groove in it so that when the iron tip is pressed onto the wire, the tip embraces the wire to melt the adhesive quickly and to make the bond relatively quickly.  The coating is applied by passing insulated wire vertically through a length of molten adhesive and then through a die.  A cleaner/holder device is used for cleaning the tip of a hot iron used for melting adhesive, or a soldering iron, and for holding the hot iron when it is not in use.  The preferred cleaner is anti-combustion treated absorbent cotton string wound on a spool which is mounted in the holder, or adhesive tape with a soft cloth backing.  A fresh cleaning surface can be provided simply by rotating the spool, or unwinding a layer of the cleaning material and removing it.
