Abstract: ABSTRACT OF THE DISCLOSURE         An improved internal voltage divider for use in a television cathode ray tube is disclosed that provides one or more temperature-invariant voltages.  The tube is subject to internal spatial temperature patterns fixed or varying with time which are incidental to tube warm-up and operation.  The voltage divider according to the invention is comprised of at least two electrically series connected resistive sections having like temperature coefficients, and having resistive values of the same order of magnitude.  Each section is so positioned and arranged relative to the aforesaid temperature patterns as to have similar average temperature experiences.  The voltage divider is connected between a relatively high anode voltage and a suitable low-voltage terminal for receiving a relatively low voltage through the base of the tube.  Means are provided for tapping off at least one temperature-invariant intermediate voltage.  Due to the simi-larity of the spatial average temperature experiences of the resistive sections comprising the voltage divider, the ratio of the resistive values of the resistive sections, and thus the ratio of voltage drops thereacross does not change despite varia-tions in the temperature patterns.  An associated method provides for positioning and arranging the discrete sections comprising the voltage divider.

Abstract: ABSTRACT     An automated system fox inserting data cards, e.g., charge, credit, identification and similar type cards, into preprinted and addressed mailing forms.  A computer, with suitable operator intervention, controls the automatic asynchronous operation of the overall system.  Each mailing form bears the account number and mailing address of the intended card recipient, and a designation of the number of cards to be inserted.          The cards are pre-embossed and encoded, and supplied in number and sequence corresponding to the requirements of the succession of forms.  The forms advance in succession from a fan-fold continuous strip supply through a read station and into an insert station.  Cards are picked from the supply in individual succession and transported past a read station at which account number data is read from the card for compari-son with the data of the form currently positioned in the insert station.  The insert station includes a number of bins corresponding to the card insert positions on the form and is controlled to receive the proper number of correctly matched cards in the appropriate bins for the form.  Should a no-match condition occur or if the corresponding number of proper cards is not satisfied, the card transport terminates to permit a visual operator check.  Operator controls permit selectively rejecting cards and forms where matching require-ments are not met and manual overrides for correction of same and for re-initiating automated operation.  Forms with the proper inserted cards are automatically burst from the strip and proceed through a folder to an output transport for stacking in sequence into an output hopper.  Sensors monitor various critical functions to assure accuracy in the automated operations.

Abstract: Abstract of the Disclosure The instant invention is concerned with transparent photochromic glass compositions which not only exhibit desirably rapid darkening and fading characteristics, but which also demonstrate the other physical and optical prop-erties required for use in ophthalmic applications.  Such glasses utilize the presence of silver chloride and/or silver bromide crystals to impart photochromic behavior in a narrowly-defined composition range within the alkali metal aluminoborosilicate base system.  Copper ions are also included in the composition to perform as a sensitizing agent.  The glasses have the capability of being either thermally tempered or chemically strengthened to comply with the United States Food and Drug Administration regulations for lenses used in ophthalmic applications.  Improved inde-pendence of temperature effects upon the photochromic prop-erties can be achieved where the copper level, expressed as CuO, is maintained between about 0.004-0.02% by weight, the chloride value, expressed as Cl, is held between about 0.1-0.25% by weight, the silver content, expressed as Ag, is included between about 0.15-0.3% by weight, and the quantity of bromide, expressed as Br, is varied between about 0.1-0.2% by weight.  The fading rate of the glasses is enhanced by maintaining the molar ratio of alkali metal oxides to B2O3 between about 0.55-0.85, the molar ratio of alkali metal oxides minus Al2O3 to B2O3 is about 0.25-0.4, and the weight ratio Ag:(Cl + Br) is about 0.65-0.95.

Abstract: TORQUE TRANSMITTING APPARATUS                    ABSTRACT        Torque transmitting apparatus (10) including a shiftable sleeve member (12) having locking and guiding splines (26a and b) for coupling a first toothed member (14) having external teeth (34) to either one of a pair of toothed members (16), having external teeth (20), and spaced on axially opposite sides thereof. Each locking spline (26a) has working faces (40) whose ends include recesses (38) for axially holding the sleeve member during the transmission of torque to prevent undesirable disengagement during the transmission of torque.  The recesses at each end of each locking spline (26a) are spaced from each other with substantially the same minimum chordal relation-ship as the end of each of the other locking splines. Each guiding spline (26b) has working faces (44) which are spaced so that the chordal thickness therebetween is substantially equal to or less than the correspond-ing minimum chordal thickness between the recesses at the ends of each locking spline.  When the sleeve member (12) is shifted on the first toothed member (14) into engagement with one of the toothed members (16), the relationship between the locking and guiding splines is such that the guiding splines serve  to maintain proper axial alignment between the three members (12, 14, 16) and the locking splines serve to prevent undesir-able axial disengagement of the locking spline 26a of sleeve  member (12) from the teeth (20) of the toothed member (16) during torque transmission.  The guiding splines (26b) also cooperate with the teeth (34) of member (14) while disengaging the locking teeth (26a)  from the teeth (20) of member (16) to axially guide the sleeve member (12) in the opposite direction.  In one preferred embodiment, the locking and guiding splines are arranged in an alternating relationship with each other.  Another preferred embodiment has three guiding splines preferably equally circumferentially spaced with respect to each other about the sleeve member.

Abstract: ABSTRACT OF THE DISCLOSURE In an oil metering valve for use in the automatic or semi-automatic lubrication of machine tools, earth moving machinery and the like, there is described an improved oil metering valve which may be inserted into existing machine bores otherwise intended to receive grease gun nozzles for manual lubrication, which results therefore in less projection of the valve from the machine than is possible with known metering valves.  This decreased projection of the valve results in turn in less damage to the valve from shock and impact.  The present metering valve is also far more economical to produce than known valves.          In this invention, the component parts of a metering valve are enclosed in a cylinder casing of uniform diameter.  The casing is formed with an oil entrance bore at one end of the casing and an oil exit bore situate at the opposite end thereof.  The oil entrance and oil exit bores are respectively determined by the flat ends of the cylindrical casing.

Abstract: A B S T R A C T     A sintering or other similar furnace having a pre-heat sec-tion in which hydrocarbon effluents are present and including a flue containing a catalytic heater and having an entrance in the chamber and an exhaust external to the furnace.  A mildly oxidizing gas such as CO2 is introduced into the flue for combination with the effluent gases being drawn out of the chamber.  As the con-taminating gases move through the flue, they pass over the heated catalytic surfaces and react with the oxidizing gas to form water and carbon monoxide, all of which is drawn out through the flue and exhausted therefrom or burned off.  The draft or negative pressure within the flue is closely controlled by an air operated Venturi pump, the air of which assists in burning exhaust gases at the flue exit.  Alternatively, the catalytic heater can be disposed in a gas barrier located between the pre-heat and sintering sections of the furnace.
