A baked product produced from such a composition has a number of improved characteristics including crumb resiliency, overall texture, structure and shelf life.

Abstract: A controlled-release particulate fertilizer composition is prepared by compacting and agglomerating particles of a foamed urea-formaldehyde condensation product into a sheet having a specific gravity of at least 1.40, the molar ratio of urea to formaldehyde in said condensation product being from 1.3:1 to 2.4:1, comminuting the compacted sheet into particulate form and separating and recovering the particles having a size of more than 30 mesh, substantially all said recovered particles having a ratio of largest to smallest particle of less than 3:1. The fertilizer is characterized by a high degree of uniformity from particle to particle in both composition and size, relatively high particle density and a combination of both quick initial and long lasting nutrient release.

Abstract: Cellulosic articles are regenerated from a cellulosic solution formed by the addition of cellulosic material to dimethyl sulfoxide and formaldehyde or paraformaldehyde by contacting the cellulosic solution with an aqueous solution having a pH greater than seven of a water soluble nucleophilic compound selected from the group consisting of ammonia, ammonium salts, saturated amines and salts of sulfur compounds in which the sulfur has a valence of less than six.

Abstract: Disclosed is a feature for use in a subscriber digital multiplexer interfacing between a central telecommunications office (CO) and a plurality of remote terminals, each remote terminal serving a number of subscribers. Calls from and to lines at the same remote terminal are identified over a special network at the central office for the purpose of by-passing the speech channels to the central office and thereby freeing the central office equipment and two channels for use in processing other calls. The special network or intra link network is activated after the called station has responded to a call. First, a check is made to see whether a station at the same remote terminal has originated a call. A tone is then sent out over the line to determine whether the call originated and terminated at the same remote terminal. If both lines are from the same remote terminal, the call is transferred from the speech channels to intra link channels as controlled at the central office over signalling channels.

Abstract: Cellulosic solutions are filtered by a process enabling virtual complete recovery and recycling of the undissolved cellulosic components of the solutions. The process comprises filtering the solution through a bed of particulate material until the build-up of undissolved material impedes the further flow of solution through the bed, mixing the undissolved material and particulate bed with a solvent to partially dissolve the undissolved material, which is highly concentrated relative to its original concentration before filtration, adding a solubilizing reactant to said concentrated partial solution of undissolved material to complete the solution of the cellulosic residues, and separating and recycling the resulting solution.

Abstract: An apparatus for selectively positioning an automotive vehicle seat is disclosed. The apparatus is adapted to be powered by an electric motor drive, such as a motor with multiple armatures or by using separate motors or by using clutch activated members driven by a single motor. Output of the motor drive is transmitted through respective gearing to lead screws within tracking structures at both sides of the seat to translate the seat horizontally. The motor drive output is also transmitted to operate individual lead screws for the vertical seat movements. To provide elevational movement of the front and rear ends of the seat, separate mechanisms from the motor drive to front and rear end lead screws are provided, these mechanisms being distributed along the seat width. These lead screws cause rotation of respective individual torsion bars at the respective front and rear ends of the seat. By the construction shown, rotation of a torsion bar raises or lowers the respective seat end.

Abstract: An intercommunication link for a multiple link key telephone system with a combination lamp-button on each handset for each available link. In each link, a line seeking intercom service is sensed to operate a relay in the link selected. A lamp flash signal on the lamp of the selected link is initiated. In this condition, all other links are disabled and none can be accessed when one link is in the lamp flashing condition. The called local number of the desired intercom station is dialed and when the called station line is answered, a second relay in the selected link operates to release the first relay. On operation of the second relay, a steady lamp indication is sent to both stations in the conversation. Other free links may be accessed at this time. Thus, only during this intercom signaling phase are the remaining free links affected.

Openings through the walls of the insulating sheets provide access to the conductors for external wiring. Spacing is provided along the edge of at least one insulating sheet to enable flattened ends of the inner layer of conductors to protrude as terminals available for connection to additional external wiring.

Abstract: Disclosed is a line circuit providing the normal line circuit functions and key system control functions within an exchange using time division switching. The line circuit may be used interchangeably for key telephones or non-key telephones. In the former case, the circuit provides the well-known key telephone features for multiple line access at each station of a plurality of stations. Each line circuit provides electronic signalling controls, such as lamp flash indicating a call awaiting an answer, lamp wink indicating a line is on a hold condition, and the fully lit line busy indication, together with audible controls for a called line, and also provides an inverted flash signal at the line circuit for trouble or problem situations.

Abstract: Disclosed is an arrangement of circuits for providing what is normally called Custom Calling or Special Services features such as signalling and switching for a call waiting or three-way calling. The apparatus shown may provide either feature or may provide both services by the selection and insertion of one of three available circuits. A plurality of common circuits are provided to operate with specific electronic logic circuits for call waiting, three-way calling or both. Circuits are plug-in PC boards using integrated circuit logic. Individual plug-in cards are provided--one for the call waiting feature, another for three-way calling and a third card is used to provide both features. The entire apparatus may be connected to the subscriber lines and to the central office equipment at the main distributing frame thereby requiring no internal wiring or circuit changes in the central office.

Abstract: In a large time-space-time division switching network, particularly one employing a multistage space-division switch, one time-division elementary time is too brief to enable transmission of addresses of crosspoints to be completed through all the stages of the multistage switch, and also provide for transmission of the speech sample. To cope with this situation, two successive network elementary times are used, each elementary time being divied into two half-times, i.e., a first half-time and a second half-time. First half-times are used for transmitting addresses of crosspoints to be closed immediately. Second half-times are used for storing data concerning further crosspoint addresses plus a speech sample. Addresses are propagated through a speech sample path according to a "staggered operation", thereby reducing the requirements for memory dedicated to crosspoint addresses.
