Abstract: GAS IGNITION CONTROL               Abstract of the Invention An apparatus for fuel ignition comprising an electrical source for providing electrical current; an electrically operated fuel ignition means; a valve means which allows passage of fuel to the igntion means when the valve means is opened; a first valve control means which will open the valve upon application of an electrical current and a second valve control means which will retain the valve means in an open position but will not initially open the valve upon application of an electrical current; an activating switch elec-trically connected between the electrical source and the rest of the apparatus so that the apparatus will not operate unless the activating switch is closed; a time delay switch connected between the activating switch and the rest of the apparatus and connected to an ignition sensing switch means so that the time delay switch stops the flow of electrical current to the rest of the apparatus if the ignition sensing switch means does not sense ignition within the time delay; and an ignition sensor for sensing ignition and an ignition sensing switch means responsive thereto.  The ignition sensing switch means, when the activating switch is closed, switches electrical current from the first valve control means to the second valve control means after ignition is sensed, shunts out the time delay relay after ignition is sensed and disconnects the ignition means after ignition is sensed.  If the ig-nition sensor ceases to sense that ignition is taking place, the ignition sensing switch again connects the first valve control means, the time delay relay and the ignition means.

Abstract: ABSTRACT OF THE DISCLOSURE         The wall of a metallurgical furnace is arranged such that cooling plates having coolant tubes and preferably made of cast iron, have cast-in spacer bosses each with a threaded protrusion for securing the respective plate to an exterior steel jacket of the wall.  There are not fastener bolts passing through the entire thickness of the cooling plate as in prior art.          The advance is in that the fastener bolts are less subject to damage as the wear of the interior surface of the wall proceeds.  The invention also facilitates the construction of the wall as the inside fireproof lining can be applied regardless of the actual arrange-ment of the cooling plates since no portion of the fasteners protrudes interiorly of the surface of the cooling plate.

Abstract: ABSTRACT OF THE DISCLOSURE This specification discloses a microwave circular polarizer for converting a linearly pol rized microwave signal to a circularly polarized microwave signal and vice versa.  A transducer, such as an orthomode junction is used to obtain a power split or a power recombination of two orthogonal linear polarizations.  To obtain the phase de-lay required to generate a circularly polarized signal from two linearly polarized signals, the polarizer includes a phase compensator with a pair of waveguides which have appro-priate width and length so that signals passing therethrough develop a phase difference therebetween and a composite circularly polarized signal results.  The amount of phase shift occurring in each of the waveguides varies with the frequency of the signal in such a way as to produce a high purity circular polarization over a broad frequency band. A phase shift of 90° can be obtained at two frequencies and these frequencies can be selected so that they are within a frequency band having a desirably low axial ratio.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved one piece cooking pan designed especially for use in baking pizza pies or like food products in a pre-heated oven, the pan having a substantially flat bottom portion with a plurality of perforations uniformly distributed over the entire extent thereof for directly ex-posing a substantial portion of the lower dough layer of a pizza pie or the like food product to the cooking heat of the oven.  The perforations preferably have filleted upper edge portions and are uniformly distributed over the pan surface such that the ratio of the perforated surface area of the bottom portion of the cooking pan to the total surface area thereof is in the range from approximately 15 to 40 percent.  The filleted upper edge portion of each perforation allows the heat to be distributed relatively more uniformly over the exposed areas of the product being cooked and avoids undesirable concentration of the cooking heat.  The uniform distribution pattern of the perforations also produces a rapid elimination of moisture in the dough, substantially reduces the separation and bubbling effect of the dough, shortens the cooking time, and makes it easier to separate the cooked product from the pan.  This specific relationship between filleted perforations and the ratio of the perforated surface area of the bottom portion of the pan to the total surface area thereof produces an accumulative affect which results in considerable cooking advantages and energy savings over prior art constructions.  The substantially flat bottom portion of the pan preferably also has a centrally disposed aperature therein as an aid to proper positioning of the pan on a device used for punching the perforations therethrough.          The pan construction of the present invention has wide applications for use in oven cooking food products such as pizza and other type pie products, cookies and numerous other food products.

Abstract: PROXIMITY SENSING SYSTEM AND INDUCTANCE MEASURING TECHNIQUE                  Abstract of the Disclosure A proximity sensing system including an improved variable inductance measuring technique to provide an indication of the proximity of a target object to a remote sensor unit 10 which includes a sensor inductor. A variable inductance measuring apparatus measures the inductance of the sensor inductor, which inductance corresponds to the proximity of a target object. The variable inductance measuring network includes a sensor current pulse generator 20 which, in each of successive system periods, establishes a time-varying current through the sensor unit 10. A sensor control loop stage 30 senses when the resulting sensor voltage reaches a predetermined level and then captures thesensor current so as to clamp the sensor voltage at this level. A retrieval stage 40 then determines the rate of change of the sensor current at the time the sensor current is zero, establishing a calibrated analog voltage of the inductance of the sensor inductor which is substantially temperature independent. The inductance analog voltage is applied to a proximity detection and switching stage 50 which provides a quantized target-near detection pulse if the inductance analog voltage corresponds to a threshold proximity of the target object. Integration over successive system periods then provides a time-average proximity voltage which is applied to a Schmitt trigger and proximity switching network 58, the output of which indicates the proximity of the target object to the sensor inductor with respect to a threshold actuation gap.

Abstract: ABSTRACT OF THE DISCLOSURE        The specification of the present invention discloses an ink duct for offset or letterpress printing machines with an ink metering unit having a series of juxtaposed zone-width metering elements which can be adjusted zone by zone to achieve different inking gap thicknesses.  The metering elements each have support and metering areas with the support areas being in constant direct or indirect contact with the duct roller due to spring pressure.  The metering areas when viewed with respect to the direction of rotation of the duct-roller are positioned after the support areas and the metering area of each metering element extends over the full zone width.  This particular arrangement prevents the generation of ink free strips on the duct roller found in prior art structures due to constant contact of the support areas with the duct roller and the interrupted positioning of the metering areas.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a interchange termination apparatus for multi-function telecommunication devices, such as key telephones. Telephone termination systems, particularly those associated with key telephones in a business office environment have heretofore required a great deal of time and expense in connection with installation, maintenance, and line and function flexibility in providing changes in an alteration of service.  The present invention overcomes these problems by providing a module for a modular termination interchange system which has a one-piece panel supporting an array of contacts.  Patch cord connectors engage selected ones of these contacts from the front side of the panel as a means of selectively programming line selection and/or function. A plurality of projections extend from the rear of the panel to support electrical connector units each having a plurality of contacts which are electrically connected to the contacts supported by the panel, the contacts of a connector unit connected to respective contacts of at least one row or rows with a particular electrical connector unit.  Complementary mating connector units are interengageable with the connector units supported by the panel projections and extend the electrical connections, via respective cables, to telephones at the distal ends of the cables. The interchangeability of the electrical connectors permits complete freedom in associating telephones with telephone lines and signaling and switching functions without relocating a telephone instrument.
