Abstract: ABSTRACT OF THE DISCLOSURE An upstream substantially cylindrical electrode is axially spaced from a downstream cylindrical electrode thereby forming a space between the electrodes.  A starter tip is extended into the space thereby forming a smaller gap between the starter tip and the closest cylindrical electrode.   An  electric  arc  is  initiated  between  the starter tip and the closest cylindrical electrode thereby initating an arc between the  substantially cylindrical electrodes.  The potential of the starter tip may be equal to  or differing from the potential  of the cylindrical electrodes.  Since the starter tip presents a small gap over a small part of the space forming the perimeter of the cylindrical electrodes, the self-starting character-istics and break-down gap characteristics which are nor-mally only present in smaller gap designs are maintained. Additionally, power supply and power requirements for the arc heater itself are minimized.

Abstract: ABSTRACT OF THE DISCLOSURE           An optical punched card reading apparatus is disclosed wherein a plurality of air passageways are disposed throughout the apparatus.  The various electrical and photo-electric com-ponents in the apparatus generate heat and through connection heat the air.  The temperature differentials cause pressure differentials which in turn cause air flow in the apparatus.          The air passageways channelize the air flow, removing dust and dirt particles that otherwise would accumulate in the photo-electric components of the apparatus.

Abstract: SLEEVE-TYPE FLUID FLOW DIVERTER                 ABSTRACT OF THE DISCLOSURE         A fluid flow diverter includes a housing    and a rotatable sleeve    mounted for rotation on an axle    and spaced inwardly from the housing walls           .  The sleeve and housing include ports   which are selectively positioned in registered or unregistered rela-tionship, depending upon which of two operative positions the sleeve assumes.  The sleeve forms a single internal chamber through which fluid always flows in the same direction in both operative positions of the sleeve.  The space between the sleeve and housing also forms a single chamber    through which fluid always flows in the same direction in both opera-tive positions of the sleeve.  The unidirectional fluid flow through the sleeve itself is opposite to the unidirectional fluid flow through the external chamber between the housing and sleeve.  The supporting connection between the cylindrical sleeve and housing walls occurs adjacent the registered sleeve and housing ports by means of mating peripheral supporting surfaces             .  In either position of the sleeve, the unused or unregistered sleeve ports face the interior wall of the housing with their supporting surfaces spaced therefrom. A filler member            is mounted to the housing interior wall adjacent the position of each unregistered sleeve supporting surface.  In actual use of a diverter         in connection with a tube type heat exchanger   or similar process device, there will be a fluid pressure differential between the supply and return sides within the diverter itself, due to the pressure drop caused by the tube   restrictions.  The supply side will have a higher pressure than the return side.  The result is that water from the supply side will tend to flow through the narrow gaps between the sleeve supporting surfaces and the housing supporting surfaces and/or the filler members in a direction from the supply or high pressure side toward the return or low pressure side.  The direction of flow through the gaps will be the same for both rotary positions of the sleeve, due to the aforementioned unidirectional fluid flow. Any loose particles or corrosion products which may appear at the various gap interfaces will tend to be washed through to the outer side and not get stuck.

Abstract: Abstract:   The present invention relates to an improved trouble detecting method for a temperature control device including a thermo-sensitive element such as a thermister or the like.  Such temperature thermo-sensitive elements are used in heating apparatuses, for example, a cooking apparatus or the like.  The detecting method includes the steps of energizing the temperature control device for a predetermined period of time, and comparing an output of the temperature control device and a reference output.          The continued energization of the cooking apparatus, for example, is dependent on the outcome of this time delayed comparison.  The time delay allows the temperature sensitive element to fall within its operating temperature range before being tested, thereby eliminating a false testing.

Abstract: Abstract of the disclosure:     Substantially non-crosslinked fluorocarbon poly-mers containing carboxyl groups are prepared starting from non-crosslinked and in some cases new, fluorocarbon polymers in which the linear macromolecules carry side chains containing the end group -CHFX (X is F or CF3).          The starting polymers are first reacted with peroxo-disulfuryl difluoride FSO2O-OSO2F to give the corres-ponding fluorosulfato derivatives containing the side chain end groups   (X is F or CF3).          In the event that X is F, these derivatives are then converted into the corresponding carboalkoxy derivatives by means of an alcohol, the fluorosulfato group being split off, and these carboalkoxy derivatives are then converted by saponification into the products containing the free carboxyl groups; the fluorosulfato derivatives can also be hydrolyzed with water, if appropriate in the presence of an inert solvent and/or bases, to give, without further treatment, the products containing the free carboxyl groups.       The fluorosulfato derivatives in which X is CF3 in the side chain end groups are first decomposed in the presence of catalytic amounts of alkali metal fluorides and/or aprotic nitrogen bases to give the products con-taining the side chain end groups   and the latter are then hydrolyzed to give the products containing the free carboxyl group.       Virtually non-crosslinked fluorocarbon polymers containing carboxyl groups are of industrial importance in the form of cation exchanger membranes in electrolytic cells, particularly in chlor-alkali electrolysis.

Abstract: ELECTRON BEAM ADDRESSED LIQUID CRYSTAL LIGHT   VALVE AND METHOD FOR CONSTRUCTION THEREOF                       ABSTRACT        An electron beam addressed liquid crystal light valve and method for construction.  A twisted nematic liquid crystal cell comprises nematic liquid crystal material sandwiched between a transparent faceplate having a transparent electrode, and a transparent, dielectric target plate.  A writing gun directs electrons at the target plate for writing thereon, a flood gun directs a cloud of electrons at the target for restoring the potential thereof, and a collector adjacent the target collects secondary emis-sion and free flood gun electrons, the writing gun, flood gun, and collector being disposed outside a field of view through the cell.  Collector potential is slightly less than that required to produce a tar-get secondary emission ratio of 1 from flood gun elec-trons.  A projection system utilizes polarizing mate-rial disposed in front of and behind the cell, and an optical system for directing light through the cell and polarizing materials.  The cell is constructed by coating one side of a glass faceplate with a trans-parent electrode and forming alignment surfaces on the electrode and target plate.  An inlet and an outlet through the faceplate are provided, the outlet being connected to a collection chamber.  The target plate is placed over the transparent electrode, separated from the electrode by a spacer.  The space within and surrounding the assembly is evacuated, after which thoroughly degassed liquid crystal material is forced by pressure through the inlet until the cell is en-tirely filled, at which point the inlet is sealed off.          Thereafter, pressure on the outside of the target plate is increased until the target plate is substan-tially parallel to the faceplate, at which time the outlet tube is pinched off.

Abstract: A.C. SOLID STATE RELAY CIRCUIT AND THYRISTOR STRUCTURE            ABSTRACT OF THE DISCLOSURE        A solid state a.c. relay has two separate and iden-tical power thyristors connected in anti-parallel arrangement.          The power thyristors are each optically switched, lateral con-duction devices with anode and cathode electrodes on the same surface.  Both are switched by illuminating their surface by reflected illumination from an LED.  Each thyristor is pro-vided with a respective control circuit which includes a MOS-FET transistor for clamping its respective thyristor gate whenever the voltage across the thyristor exceeds a given absolute value or whenever there is a high dV/dt transient across the thyristor.  The control circuit for the control transistor includes a capacitance divider, one element of which is the distributed capacitance of the control transis-tor; a resistor and a zener diode.  The control circuit com-ponents are integrated into the thyristor chips.  Each of the two identical power chips and the LED chip are spaced from one another and mounted on an alumina substrate.  Two lead wires are stitch-bonded to the electrode pads of the two chips to connect them in anti-parallel relation, and are then stitch-bonded to two respective conductive sections on the alumina substrate.  Each thyristor consists of a plural-ity of individual lateral thyristor elements connected in parallel.  Each element has an active base region which con-tains a respective cathode region.  Each of the base regions is carried in a common conductivity type body.  Extending fingers of a continuous anode electrode partly enclose each individual base region to enable the parallel connection of the individual devices.  The thyristor base and emitter zones are surrounded by an auxiliary P region which is resistively connected to a field plate and the cathode electrode to im-prove emitter collection efficiency.  The cathode electrode and anode electrode are interdigitated.  The cathode electrode is connected to spaced, parallel, generally rectangular emit-ter regions which are disposed in respective bases between loops of the cathode electrode.

Abstract: THERMAL ANEMOMETER                 Abstract of the Disclosure A thermal anemometer arranged to measure air velocity over a wide range of ambient temperatures and velocities, and a method of measuring such air velocity free of influence of ambient temperature, in which the anemometer comprises a probe containing two separate and distinct sensing elements, and a hand held electronic read out unit that contains sensing signal electronic processing circuitry, function control, and an analog read out meter, with the probe and read out unit being interconnected by a self coiling cable.  The probe sensing elements are a self heated thermistor and a solid state temperature sensing device, that are separately but simultaneously exposed, in use of the instrument, to the air flow, with the energy consumed by the thermistor, and its resulting signal, being an indication of both the velocity of the air stream and the difference in temperature between the forced operating temperature of the thermistor and the air stream ambient temperature.  The solid state temperature sensing device is a temperature sensing transistor, and develops a signal that is proportional to the air stream temperature.  The two signals are electronically combined at the read out unit to eliminate the effect of any ambient temperature variations, to provide an air stream velocity reading at the meter that is independent of ambient temperature.

Abstract: AC voltage stabilizer easily convertible into uninterruptible power supply (UPS).     ABSTRACT            An electronic AC voltage stabilizer is described using a class B amplifier output stage which is fed by a full-wave rectified sinewave voltage. The input voltage to (the phase inverter of) the class B amplifier output stage is kept in phase with the aforesaid sinewave voltage, which causes the power losses over the output stage to be very low. As compared to other electronic AC stabilizers the apparatus according to the invention offers high efficiency and simplicity. The AC stabilizer can easily be converted into a true UPS by adding a battery which by intermediary of a battery interface connects the conditioned battery voltage to the push pull amplifier output stage when the network fails.
