Abstract: ABSTRACT      A furniture frame includes a plurality of frame members having rectangular tubular cross-sectional configurations.          One of the frame members has a pair of elongated generally wedge-shaped parts rigidly attached thereto in spaced apart relation to one another thereon and projecting therefrom in generally parallel relation.  A pair of other of the frame members have a cross brace frame member extending between and at its opposite ends rigidly attached to the other frame members so as to dispose the other frame members in generally parallel relation to one another.  Each of the other frame members at same one of their opposite ends is open with generally wedge-shaped pockets defined therein by indented portions of the frame members located near the open ends thereof.  The wedge-shaped pockets have configurations generally complementary to that of the wedge-shaped parts for removably receiving the wedge-shaped parts in a relatively tight, frictional fitting relation to provide the pair of other frame members in an assembled relationship relative to the one frame member.  An attachment arrangement is provided for releasably securing the other frame members and the one frame member together once the wedge-shaped parts have been received within the wedge-shaped pockets and the members are in their assembled relationship.

Title: Removal of volatile acids from nmp solvent vapors with sacrificial metal and ion exchange
Inventor: LEIGHTON MILTON D
IPC: C07D207/267
Filed: 1989-03-23
Granted: 1994-03-08
Abstract: ABSTRACT OF THE DISCLOSURE           Volatile acids present in n-methyl pryrroli-done vapor from solvent extraction processes can be reacted with sacrificial metals such as magnesium to concentrate the acid salts into a small volume of oil/NMP.  Steam stripping removes NMP from the oil/NMP mixture while simultaneously springing a portion of the light carboxylic acids from their salts, the acids going with the NMP.  This condensed NMP stream con-taining the light carboxylic acids is contacted with an ion exchange resin which removes the acids from the NMP.  The purified small volume of NMP is returned to the extraction process.

Abstract: ABSTRACT OF THE DISCLOSURE A MOS (preferably CMOS type) analog NOR amplifier suitable for use in building a programmable array logic (PAL) or the like, or for other usuages. The analog NOR amplifier consists of a reference MOS transistor and first pull-up means at one branch and a plurality of input MOS transistors and second pull-up means at another branch with a constant current source connected to the sourct terminals of these MOS transistors, which forms a configruation similar to a differential amplifier. With the gate terminals of the plurality ofinput MOS transistors as logic input ends, the drain terminals of the same will act as the output end of a standard NOR gate and the drain terminal of the referenceMOS transistor will behave as the output end of a standard OR gate. On account of the differential amplifier structure, the MOS analog NOR amplifier will not generate current spikes when in logic transient transition and the amplifier gain can be kept low thereby acquiring a low output impedance to further improve the logic transient response. Furthermore, a constant current source is provided to be utilized in the MOS analog NOR amplifier, whereby the Miller capacitance of the amplifier will be maintained at almost zero so that a high speed but cost-effective NOR gate is achievable.

Abstract: ABSTRACT            PARALLEL PROCESSING METHOD AND DEVICE FOR RECEIVING AND TRANSMITTING HDLC SDLC BIT STREAMS            This invention relates to a parallel processing method and device for receiving and transmitting HDLC  (high level data link control) frames, which improves the performance of a data communication apparatus in a significant way.            The bit streams transporting the frames,  received from lines 6 are inputted in to register 12, in such a way that n bits are processed during a time interval T. Parallel processor 10 counts the consecutive bits at 1 from the n bits received in interval T and from the bits received in the previous interval T-1, to determine when this number is found equal to 5 which bits have to be deleted, and when this number is found equal to 6 whether a flag is received.  As a result it rassembles N-bits characters, with N>n, in register 16.            The frame characters to be sent on lines 6 are stored into register 28, and processed in parallel in a time interval T by processor 10 which inserts 0 after five consecutive 1 as a function of the value of the N-bits and as a function of  the  bit  of  the  previous  character,  to  store  into register 32, the bits which are sent on lines 6.

Abstract: A constant tension hoisting system is provided for raising and lowering an object between a platform and a surface undergoing vertical motion relative to the platform, such as raising and lowering a lifeboat from a seagoing vessel to the sea in rough weather. The system operates in a normal hoisting mode to raise or lower the object, and in a constant tension mode when the object is supported on the surface. The system is changed from the normal hoisting mode to the constant tension mode at the moment when the object being lowered is first supported by the surface, and a slack condition exists in the cable. The changeover from the normal hoisting mode to the constant tension mode, is performed by a solenoid-operated mode selector responsive to a proximity switch operated by a lever arm engaging the cable. The hoisting system is operated by a single, manually-actuated control lever, which mechanically activates the proximity-type control switches. An auxiliary motor connected to a ring gear of a planetary-type final drive operates the hoisting system in the constant tension mode, while a main motor operates the system in the normal hoisting mode.
