Title: Glycidyl azide polymer
Inventor: AMPLEMAN GUY
IPC: C07C247/04
Filed: 1991-10-03
Abstract: ABSTRACT OF THE DISCLOSURE         Glycidyl azide polymers, which are used as binders in composite explosive and propellant compositions, include hydroxyl groups which react with the isocyanate curing agent normally used in such compositions. Since the functionality of available linear glycidyl azide polymers is less than two, trios and/or triisocyanates are needed to crosslink the chains to form a matrix.  A glycidyl azide polymer with increased functionality (higher than two) and reactivity obviates the need for triols and triisocyanates in the compositions.          Moreover, a glycidyl azide polymer with primary hydroxyl groups would give faster curing reactions at lower temperatures without gassing problems, eliminating the need for a catalyst.  Examples of glycidyl azide polymer having increased functionality have one of the formulae:                        wherein R is   wherein m and n are different from zero, and m + n is 4 to 60.

Title: Process for separating ammonia from gases in particular the exhaust gases generated by combustion processes
Inventor: MARTIN JOHANNES
IPC: B01D53/34
Filed: 1991-11-07
Abstract: ABSTRACT            In a process for separating ammonia from gases, in particular from the exhaust gases generated by combustion process, in which the ammonia is either formed or generated, or in which ammonia or a substance that forms ammonia under the effects of temperature, is introduced, a substance from the group of zeoliths is added in finely divided form to the gas that is to be purified as a treatment medium, this being done by thorough mixing with the gas.  The compounds that are added have the advantage that they not only remove the ammonia from the exhaust gases very effectively by absorption, but can bind it very strongly in their internal structure, which effectively avoids the renewed release of the ammonia during final disposal.

Abstract: A vehicle 10 which inspects pipes 12 using flux-leakage has a flux generating electromagnet 14 and foils 18, 20 to transfer the flux to the pipewall 12.  Sensors 22 detect flux forced to leak from the pipe by defects.  The vehicle is required to pass 1-D bends as shown and has a swivel 40 having a load bar 48 on which is a link 46 of a towing chain 26. On straight pipe the link 46 occupies a first position nearer the axis 44.          In a bend the swivel turns so that the link 46 can slide along the load bar 48 to a second position further from the axis 44.  This reduces the angle which the chain 26 makes with the axis 44 and jamming of the vehicle 10 in the bend is avoided.   In a modification the load bar instead of being to one side of the axis 44 extends symmetrically on both sides of the axis 44.

Title: Hitch for fastening a tow strap long running eye knot to a life-buoy
Inventor: NOWLAN JEAN
IPC: B63C9/26
Filed: 1992-06-02
Abstract: ABSTRACT   This invention relates to a hitch for fastening a tow strap with a long running eye to a rescue buoy and other devices. It is common for life-buoys and other rescue equipment to have round tie-holes for fastening ropes or straps. However, these round tie-holes are inefficient for fastening tow straps, because the straps areconstricted when tied. This constriction results in a loss of strap strength. Moreover, this constriction makes it hard to undo these tight knots and makes itimpractical to change from one type of tow harness to another. I have found thatthese disadvantages may be overcome by fastening the tow strap to the buoy with a long running eye loop, by straightening one side of the tie-hole and by adding awedge block to hold the running eye knot. This tie-hole with wedge block maintains a flat contact of all parts of the tow strap within the knot and prevents sharp bends and constriction of the tow strap. This hitch conserves the greateststrength of the tow strap and makes it easier to tie and untie the long running eye knot. The wedge block also limits the tightening of the long running eye knot, making it easy to undo. This hitch allows for a fast and easy change of tow harnesses.

Abstract: A second-order digital sigma-delta modulator uses a single multibit parallel adder (AD) in time division multiplex fashion with an integration delay circuit (DL3) between the output of the adder and the output quantizer (TD). the output of the integration delay circuit being also coupled to one adder input through a 2-way multiplexer switch (SW1) and to the other adder input via an additional delay circuit (DL4).  In one position of the switch, an input sample is added to the output of the additional delay circuit and in the other, outputs from both delay circuits are added.  To account for the absence of subtractors fed from the quantizer, some of the bits outputted by the integration delay circuit are passed in inverted form, both to the additional delay circuit (INV3) and, from the inverted (INV1) output of the quantizer eventually through a third delay circuit (DL5), to the switch.
