Abstract: PROCESS FOR THE PREPARATION OF VISCOSITY       STABLE POLYURETHANE SOLUTIONS                   ABSTRACT OF THE DISCLOSURE         A process is described for the preparation of pre-dominantly linear polyurethane solutions which comprises a)  reacting A)  an organic diisocyanate or diisocyanate mixture op-tionally containing small portions of a triisocyanate with B)  one or more polyhydroxyl compounds which are predomi-nantly bifunctional and generally have molecular weights of from about 400 to 5000 and C)  optionally one or more chain lengthening agents having at least two isocyanate reactive hydrogen atoms and molecular weights of from about 32 to 399, wherein the proportion of isocyanate groups to the number of isocyanate-reactive hydrogen atoms is in the range of from about 0.9:1 to 1:0.9, and b)  when the polyurethane formed has reached the required viscosity, adding a monofunctional, low molecular weight oxime having a molecular weight of from about 73 to 325, preferably butanone oxime, to the reaction mixture as chain breaking agent in a quantity equivalent to or in excess of the equivalents of unreacted isocyanate groups.        The new chain breaking agents are simple compounds which effect rapid chain breaking and have no undesirable side effects as regards subsequent breakdown of the chains and even enable further synthesizing reactions to be car-ried out if desired, for example with diamines.

Abstract: ABSTRACT OF THE DISCLOSURE     A toothed bar, for disturbing shellfish from the sea bed for collection in net or chain belly, is secured to frame by means of resiliently deformable blocks which allow the toothed bar to undergo resilient movement to ride over obstacles on the sea bed. The lower end of each block to which the toothed bar is secured, is encased in a metal cap to reduce wear. The block is held between metal plates the rear one of which is curved outwardly at its bottom end to allow the required degree of rearward flexure of the block.          The invention provides advantages of operation particularly in reducing the risk of damage or loss due to obstacles on the sea bed.

Abstract: ABSTRACT     A sustained controllable gas flame.  The hydrogen generator utilized provides gasses from water having impurities and other gasses entrapped therein.  The hydro-gen generator has a chamber for holding a quantity of water and a pair of non-oxidizing electrodes are located in the chamber. A rippling wave form electric potential is applied across the electrodes without any change of polarity and the current flow is limited.   The gasses separated from the water comprise combustible gasses such as hydro-gen and oxygen and non-combustible gasses, such as nitrogen.          The nitrogen, oxygen and hydrogen are mixed as they are released in the process and collected as a mixture of gasses in a collection chamber of the generator.  A nozzle having one or more ports of a given configuration is con-nected through a line to the uppermost region of the gas collection chamber of the hydrogen generator.  The nitrogen reduces the velocity and temperature of the burning flame from that of the hydrogren/oxygen mixture.  To further control the temperature and velocity of the burning gas mixture there are added to the collection chamber other non-burnable gasses.  The configuration of the nozzle and its port opening for sustaining a flame is dependent on the mixture of gasses utilized and restricted thereby. An increase in the size of the flame requires additional port openings to prevent blowout.

Abstract: Abstract of the Disclosure The fact that meatballs in a casing have been heated to a predetermined temperature sufficient to inacti-vate the virus of foot and mouth disease is permanently indicated by using a holder device to position a tempera-ture recorder at the thermal "cold-spot" of the mass of meatballs.  The temperature recorder is preferably of the type which permanently changes color when heated to the desired predetermined temperature, and the holder may be an apertured disc to which the temperature recorder is secured by an enveloping netting.  An import inspector will then be able to ascertain that the meat has been previously heated to the desired temperature by observing the color of the temperature recorder.

Abstract: METHOD AND APPARATUS FOR MEASURING REACTIVITY            OF FISSILE MATERIAL                       ABSTRACT     Given are a method and apparatus for measuring nondes-tructively and non-invasively (i.e., using no internal probing) the burnup, reactivity, or fissile content of any material which emits neutrons and which has fissionable components.  No external neutron-emitting interrogation source or fissile material is used and no scanning is required, although if a profile is desired scanning can be used.  As in active assays t her  both reactivity and con-tent of fissionable material can be measured.  The assay is accomplished by altering the return flux of neutrons into the fuel assembly.  The return flux is altered by changing the reflecting material.  The existing passive neutron emissions in the material being assayed are used as the source of interrogating neutrons.  Two measurements of either emitted neutron or emitted gamma-ray count rates are made and are then correlated to either reactivity, burnup, or fissionable content of the material being assayed, thus providing a measurement of either reacti-vity, burnup, or fissionable content of the material being assayed. Spent fuel which has been freshly discharged from a reactor can be assayed using this method and appa-ratus.  Precisions of 1000 MWd/tU appear to be feasible.

Abstract: Interfacing A Communication Network Abstract A carrier sense multiple access with collision detection strategy ascertains for a particular network configuration the network propagation time, and promulgates a parameter p providing an indication thereof to each station of the network.  Each station of the network stores p for use in making decisions about collisions. Whenever a modification of the network is made changing the propagation time, a new value of p is promulgated to the stations of the network so that the collision related decisions made by each station's interface controller will reflect the new network configuration.  Communications are formed in packets with a preamble long enough to propagate the network.  The controllers analyze the signals they receive to discern whether a packet has been contaminated by an interference.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to an apparatus primarily intended to serve as a pressurized consisto-meter suitable for determining the thickening time of cement slurries under temperature and pressure con-ditions similar to those encountered in the cementing operations involved in oil and gas well completions. A slurry cup, which also serves as the pressure vessel, is held stationary in an externally heated jacket while a DC motor generator is used to rotate a mixing paddle. The motor current drawn by the generator is used as a measure of slurry consistency and the speed of rotation of the mixing paddle is controlled by a gener-ator feedback signal.  Modifications to the apparatus enable the apparatus to be used as a pressurized rheo-meter,as an on-line viscometer, as a fluid loss cell, or as an apparatus for conditioning a cement slurry before transferring this slurry under pressure to a standard high temperature, high pressure fluid loss apparatus.
