Abstract: S P E C I F I C A T I O N     BALE ACTUATED CONTROL FOR THE REAR ROLL FORMING CHAMBER IN A CROP MATERIAL ROLL FORMING MACHINE                 ABSTRACT OF THE DISCLOSURE A roll forming machine picks up crop material and forms, twine wraps and discharges rolls or large round bales thereof as the machine is continuouslymoving across the field.  The machine has a mobile frame supporting a pickup and a floor, the latter supporting a lower conveyor. A front upper apron is supported on the frame above a front portion of the lower conveyor and floor and defines a front roll forming region therewith. A rear upper apron is supported on the frame above a rear portion of the lower conveyor and floor and defines a rear roll forming region therewith. Formation of a crop material roll is initiated in the front region and completed in the rear region after the roll has been partially formed in the front region and transferred to the rear region. Mechanism on the frame is operable to adjust an inlet opening to the rear roll forming region between a first size to allow the delivery of crop material therethrough for forming a roll in the rear region and a second size larger than the first size and adapted to allow the transfer therethrough of the partially formed roll to the rear region. Further, controls as provided on the frame for controlling the operation of the inlet opening adjusting mechanism. The controls include a pivotally mounted paddle which is positioned for engagement by the transferred roll as the roll arrives in the rear region. Such engagement actuates the paddle to cause the controls to cause operation of the adjusting mechanism to adjust the inlet opening of the rear region from its second to its first size.

Abstract: Abstract of the Disclosure A validator for a card bearing a code readable by moving the card forward past a reader, particularly for use in a vendor to control vending, in which the card is transported forward from an entry position past the reader to an escrow position.  If read as valid, the card is maintained in the escrow position pending the user's decision to have the card collected or to obtain return of his card.  If the card is read as invalid, it is im-mediately fed back to the user.  The card transport is such as to prevent a valid card from being pulled back out of the validator as by a string or tape attached to the card, and the validator is so constructed that it is easily opened for servicing, including removal of a card which may become jammed in the validator.

Abstract: ABSTRACT   A metal preheating apparatus has a box-like structure including, a bottom, a top wall, a pair of sidewalls, and a pair of end walls forming an enclosed receptacle. Fluid channels are defined between the outer surfaces of a pair of inner walls spaced inwardly from the sidewalls and the inner surfaces of the sidewalls. The upper and lower edges of the inner walls terminate short of the top wall and short of the bottom to place the upper portion of the receptacle in fluid communication through the fluid channel with the lower portion of the receptacle. A horizontally, oriented, load supporting grate member is positioned intermediate these apertures and extends longitudinally between the end walls and transversely between the inner walls. The bottom of the structure is open. The top wall of the structure contains an upper door for charging scrap metal into the upper portion of the receptacle so that the scrap metal is supported by the grate member. An end door is provided in one of the end walls to discharge the scrap metal from the upper portion of the receptacle. In operation, scrap metal is charged into the upper portion and the upper door is closed. The entire apparatus is then positioned over hot metal ingots that have just been removed from their molds. The heated air surrounding the ingots rises through the scrap metal. As the air passes upwardly by convection through the scrap metal, heat is transferred from the air to the scrap metal, cooling the air and heating the scrap metal. The cooled air enters the fluid channels from the upper portion of the receptacle, travels downwardly by convection through the fluid channels, and exits from the fluid channels into the lower portion of the receptacle. The air then passes by the ingots and is reheated to begin another convection cycle for preheating the scrap metal.

Abstract: Abstract of Disclosure A process for the production of fertilizer by reacting sulfur oxide containing gas and water in a multiple state reactor to form sulfur containing acid and reacting the sulfur containing acid with a basic salt which may be solubilized as a result of the acid-base reaction, the basic salt selected from the group consisting of calcium, ammonium and potassium ions, the calcium being derived from a salt selected from the group consisting of phosphatic and nitrogeneous salts, to form a fertilizer selected from the group consisting of phosphatic, nitrogeneous and potassium fertilizers and combinations thereof.  The combined sulfur oxide absorption and solubilization of basic salts is conducted at the solution pH of 2.5 to 5.  To enhance the further absorption of the sulfur oxide, a solution pH of 3 to 8 is used.  This process is suitable for the utilization of sulfur oxides resulting from the combustion of high sulfur containing fossil fuels and sulfur producing chemical processes.  The process of this invention enables the utilization of low concentration sulfur acid in the solubilization of phosphate rock utilizing a multiple state reactor.  To obtain solubilization of untreated phosphate rock, oxidation of the sulfur dioxide to sulfur trioxide and conversion to sulfuric acid is preferred while solubilization of pretreated, defluorinated phosphate rock may be achieved by sulfurous acid formed from sulfur dioxide thereby eliminating the need for oxidation. Lower grades of phosphate rock are suitable for use in the process of this invention.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic telephone switching system is described having peripheral units including a plurality of subscriber and line circuit, a plurality of trunk and tie line circuits, at least one attendant line circuit, a plurality of signaling tone receivers, and a plurality of link control circuits. Switching is carried out by a one wire speech path switching matrix and a one wire tone switching matrix. The system is centrally controlled and includes a central processing unit, program memory, a scratch pad memory and a customer memory. Information, commands and addresses are communicated between the peripheral units and the central control and within the central control via bus lines. The bus lines between the peripheral units and the central control transmit data with lower rise time pulses than the bus lines interconnecting the components of the central control. Each electronic crosspoint switch has a two terminal conducting path and a control terminal for controlling the state of conduction of the conducting path. Different conducting path terminals of the speech path matrix and tone path matrix crosspoint switches are operated by the same peripheral line unit. The matrix coordinates to be operated are defined by polling the different peripheral units connected to the coordinates in question.

Abstract: THERMAL OIL RECOVERY METHOD        (D#73,334-]-F) ABSTRACT OF THE DISCLOSURE Heavy or viscous oils may be recovered from subterranean deposits by one or more wells each of which is provided with at least two separate communication means from the surface of the earth, one in fluid communication with the upper part of the formation and the other well being in fluid communication with the lower part of the formation, each of said communication means being completed so as to permit injection of steam or mixtures of steam and other materials into the formation and production of heated viscous petroleum therefrom.  A relatively impermeable barrier is formed between the portions of the formation where the communication is established, oriented horizontal-ly and extending some distance into the formation.  The oil recovery process comprises several separate phases of operation.  In the first, steam is injected into the formation using both communication means simultaneously for a period of time followed by a soak period if desired, followed by production of heated oil from both parts of the formation using both communication means simultaneously. In the second phase, steam is injected into only one of the communication means, which may be the one in communication with either the top or bottom part of the formation, and oil production is taken from the other communication means.  The horizontally-oriented impermeable barrier forces the steam to move a considerable distance into the formation away from the point of injection before moving back toward the production inlet.  The injection-production sequences are then reversed, so the process effectively pressure pulses the formation to increase the distance into the formation that the push-pull steam injection process is effective.
