US Patent:

42034167, May 20, 1980

Filed:

Nov 25, 1977

Appl. No.:

5/855026

Inventors:

Ralph E. Simpson - Upland CA
Michael L. Simpson - Ontario CA

Assignee:

Simpson Enterprises - Upland CA

International Classification:

F24C 1510

US Classification:

126212

Abstract:

A device for holding a pot on a gas range burner in a moving recreational vehicle. The device is attachable to a burner grate of the type having radial bars with sloping lower edges, and it has a deck with lateral edges that interfit with a neighboring pair of the radial bars so as to support the deck on the bars and permit it to span the space between them. A pair of locking levers are pivotally supported at a common point under the deck. From their common pivot point, the locking levers extend forwardly and terminate in outturned, downwardly offset feet designed to swing outwardly into frictional contact with the lower edges of the neighboring radial bars from points intermediate the bars. To the rear, the locking levers are formed into a pair of handles. Mounted above the deck on a pair of pivoted brackets are two clamping members with forward portions formed into curved arms for embracing the pot, and rear portions serving as handles.

Abstract:

A lightweight, collapsible frame for holding a plastic trash bag upright to receive trash. The frame includes a triangular base formed from three pivoted strips that can be folded together for storage when not in use. Additionally, the frame includes three tubular posts or props which are removably attachable to the corners of the triangular base in such a way as to stand upright around the space above the base. Each of the tubular posts has a crosspiece fitted to its upper end for pivotal movement between a first position crosswise of the post, where it serves to prop up the wall of a trash bag in the space above the base when the top of the bag is folded down over it, and a second position at right angles to the first for easy packing and storage purposes. A spring clip is fastened to each of the tubular posts near its upper end. A trash bag is attached to the frame for use by placing it in the space separating the upright posts above the base, with its bottom end down; folding its top edge outwardly over the crosspieces on the posts (after each has been placed in the crosswise position mentioned above) far enough to reach the spring clips on the posts; and securing the edge of the bag in the spring clips.

Abstract:

Multiple speech bit-stream frame buffers are used between the controller and the speech decoder. Whenever excessive or missing speech packages are detected, the speech decoder switches to a special corrective mode. If there is too much, the buffered frames are played out fast; if there is too little the buffered frames are played out slowly. For the fast play, some speech information has to be discarded, while for the slow play some speech-like information has to be synthesized. The speech may be handled in sub-frame units, which may be 52 samples at a time. Low energy, silent or unvoiced sub-frames, which also indicate non-periodicity, are detected and manipulated. Moreover, the decoded signal is manipulated at the excitation phase, before the final LPC synthesis filter, resulting in a transparent perceptual effect on the manipulated speech quality. Additionally, the buffers are enlarged such that the problem caused by controller asynchronicity is eliminated. Further, for bulk delay caused by multiplexing data and speech transmissions, the buffers maintain the smallest number of speech packets necessary to prevent buffer underflow during a data packet transmission while minimizing speech delay and preserving data transmission efficiency.
