Abstract: (U.S. 925,644) ABSTRACT OF THE DISCLOSURE         Carbonaceous material is gasified in the presence of an added potassium salt having poor catalytic activity as compared to potassium carbonate and a sodium or lithium compound.  The added sodium or lithium compound apparently activates the relatively noncatalytic potassium salt thereby producing a substantial catalytic effect on the gasification reactions.  In general, activation of the noncatalytic potassium salt will take place when the sodium or lithium compound in-troduced into the reactor is either a salt of a weak acid or a salt of a strong acid that is converted to a sodium or lithium salt of a weak acid in the reactor at gasification conditions.

Abstract: ABSTRACT OF THE DISCLOSURE       In order to stabilize the heave-mode of a surface effect vehicle during operation at "tip-toe" height, con-trolled leak ports are disposed around the periphery of the vehicle.  The controlled leak ports comprise variable valves responsive to plenum pressure by way of an actuator.          During heave-mode instability, the valves are methodically actuated each cycle when the pressure in the plenum exceeds a threshold level.  Large air volume handling capacity is obtained by employing a sufficient quantity of valves.          Additionally, a particular valve configuration presently preferred employs two abutting, coaxial, mutually-rotatable discs provided with alignable apertures distributed across their respective faces to obtain rapid actuation and deac-tuation and thus selectively control large volumes of bleed air.

Abstract: 16                  48,152 ABSTRACT OF THE DISCLOSURE  A current limiting circuit interrupter comprises a molded case, separable contacts disposed in the case, the contact arms supporting one of the contacts, an operating mechanism connected to the contact arm to move the arm be-tween open and closed positions,  and a slotted magnetic drive device generating electrodynamic force on the contact arm during extreme overcurrent conditions to rapidly separ-ate the contacts.   The magnetic drive device includes a molded housing forming a slot having insulated walls dis-posed about the contact arm, and a stack of U-shaped lamina-tions of magnetic material fitted into the housing.  The space between opposing walls of the housing is slightly less than the thickness of the lamination stack so that the laminations may be snugly press-fitted into the housing. The housing is then secured to the case in such a manner that the laminations are captured and securely positioned without the need for rivets or other fastening means extend-ing through the lamination stack.  The housing also includes molded recesses for receiving a compression spring to pro-duce  contact  force when  the contacts are in the closed position, and a molded stop member to limit the movement of the contact arm when the breaker is in the open position.

Abstract: ABSTRACT OF THE DISCLOSURE A saddle for a U-bolt clamp is formed of a pair of tubular housings arranged to receive and slide axially upon the legs of a U-bolt having a semicircular bight, with the housings connected by web portions consisting of a pair of initially parallel planar sections of sheet steel that are welded together in substantially full face contact and ex-tending transversely between the housings integral therewith.          The upper (bight facing) edge of each planar section is curved as a semicircular recess on the radius of the U-bolt bight.  The mid portion of each planar web section is, for its entire length between the tubular housings, embossed with deep ribs to provide web stiffeners materially reinforcing the entire web portion of the saddle.  The lower edge of each web section is formed with an out-turned lateral flange over its full length, which flange lies in a plane normal to the longi-tudinal axes of the tubular housings and additionally reinforces the web section against horizontal distortion and twist when securing nuts threaded on the ends of the U-bolt legs are drawn up against the lower end faces of the tubular housings to tighten the clamp.  The flanges add about 50% more metal to the web area at its narrowest point.

Title: Method and apparatus for editing digital signals  recorded on a record medium
Inventor: TANAKA MASATO
IPC: G11B27/038
Filed: 1980-01-28
Granted: 1982-10-12
Abstract: ABSTRACT OF THE DISCLOSURE           Digital signals are reproduced, delayed, and then mixed with edit digital signals which are supplied from a suitable source.  Mixing is carried out while gradually decreasing the value of one digital signal while concurrently gradually increasing the value of the other such that one gradually is replaced by the other.  The resultant mixed digital signals are recorded in data blocks formed of data words and an error check word by a recording transducer which is spaced from the reproducing transducer by an amount corresponding to the aforementioned delay.  In one embodiment, the data blocks are recorded in a single track.  In another embodiment, the data blocks are recorded in separate parallel trcks, with the data words in such tracks being recorded in substantial time-alignment; and the error check word in each block being associated with data words that are included in blocks that are, for example, m data blocks away.  The sequences of data blocks are supplied to respective recording transducers by separate switch circuits which are operated at different times, whereby switching noise, if present, is recorded in different data blocks in the respective tracks.  In an alternative embodiment, the data blocks in one track which normally are in time-alignment with corresponding data blocks in the other track are displaced therefrom, and sequences of data blocks are switched to the respective recording transducers concurrently.  Because of this displacement of the data blocks, even if switching noise is recorded at the same locations in both tracks, it would not interfere with normally-related data words in the respective tracks.
