Abstract: Abstract A method for the photometric analysis of a liquid sample in which different path lengths of the sample are analyzed photometrically.      In order to reduce the time needed for analyzing a large number of samples, the analysis is carried out with a light beam which is generated by an immobile light source;  the sample is introduced into a cuvette which has at least two regions with different cross-section lengths; and the cuvette is continuously moved along a circular path in such a manner that in the course of the photometric measurement the light beam passes through at least two of the regions in succession.

To  prepare  the  aqueous  activating solution, a dry activating composition is prepared which is adapted to be dispersed in water at a controlled concentration and which comprises a mixture of about 60 to about 90% by weight  of  a  particulated  dried  reaction  product  of  a titanium-containing compound and  sodium phosphate compound containing at least about 0.005% by weight titanium with the balance  comprising  tetrasodium  pyrophosphate.    The  dry activating composition is dispersed in the aqueous solution to provide a total concentration of from about 0.1 to about 10 g/l.  In accordance with the process aspects of the present invention, the aqueous dispersion containing the activating composition is applied to cleaned metal  surfaces  such as steel, zinc and aluminum before the following zinc phosphating step whereby improved phosphating coatings are produced.

Abstract: ABSTRACT OF THE DISCLOSURE:       A method of producing non-flammable, high-temperature resistant polyimide fibers according to the dry-spinning technique from a solution in aprotic organic solvents.     The fibers obtained are to have irregularly lobed or serrated cross-sections, a wool-like smooth hand and high brightness. The dry-spinning process is carried out in a spinning column, wherein a 20 to 40 % solution of the polyimide is spun from spinnerets having circular orifices, the orifice numbers ranging from 20 to 800 and the orifice diameters from 100 to 300 µm. An extrusion speed of between 20 and 100 m/min, a take-up speed of between 100 and 800 m/min, an amount of spin gas between 40 and 100 m3/h under standard conditions and a spin gas temperature of between 200 and 350°C are applied.          The tows leaving the spinning column, which contain residual solvent from 5 to 25 % by weight - based on dry polymer - and have a single filament titer of between 3.5 and 35 dtex, are washed in hot water, then they are dried to a moisture content of less than 5 %, subsequently are drawn at high temperatures and, if desired, are crimped and cut into staple fibers.

Abstract: METER MOUNTING                         ABSTRACT A mounting for adjustably securing a meter to a pipe, The preferred embodiment of the mounting includes a one-piece, unitary saddle member, leveling member, and U-bolt which extends substantially about the pipe and is attached to the saddle member to secure it to the pipe.  The saddle member has front and rear portions with the leveling member being mounted to the front portion of the saddle member.  The rear portion of tile saddle member has two serrated sections extending outwardly of the center of the saddle member and the mounting sits on the pipe with only the leveling member and each of the two sections of the rear portion engaging the pipe.  In operation, the saddle member is rotated about the longitudinal axis of the pipe to the desired position and secured in place with the U-bolt.  The saddle member is then pivoted generally about an axis transverse to the pipe's axis by selectively moving the leveling member to raise or lower the front portion and rock the saddle member about the two sections engaging the pipe.          The two sections flare outwardly for fitting a wide variety of different, sized pipes while still maintaining the seating of the mounting as a three point or area contact on the pipe.  Additionally, the serrations have rounded end portions so that the saddle member can be easily and smoothly rocked about them to position the meter in a true vertical orientation for proper operation.

Abstract: Abstract:        A microcomputer controller coin telephone set prevents coin call fraud and also checks the operational readiness of the telephone set to prevent the acceptance of coins into a hopper for later collection by a coin box unless or until the set is fully functional.  Capable of being interrogated remotely, a local memory is used for storing coin deposit information and generating coin deposit signals in order of deposit to a central office.          In those instances where the line power drops below that necessary for full operation as a coin telephone, low power sensing circuits convert the telephone to the POTS mode which allows speech and dialing capabilities.          Similarly, any type of chute failure, or a full hopper causes the telephone to revert to the POTS mode.  While in the POTS mode, any coins deposited in the telephone are returned to the customer.

Abstract: ABSTRACT OF THE DISCLOSURE            A continuous process for the grafting of ethylenically unsaturated monomers onto homopolymers of ethylene and copolymers of ethylene and C4 - C10 higher alpha-olefins is disclosed.  The process involves feeding to an extruder an admixture comprising (i) a major portion of the above polymer of ethylene, (ii) the monomer, (iii) 25-500 ppm of an organic peroxide and (iv) a minor portion of a normally solid thermoplastic polymer having a melting point of less than 185°C and a shear viscosity at 200°C and a shear rate o 400 sec-1 that is not more than 50% of that of the polymer of ethylene.  The organic peroxide is in the form of a composition with the thermoplastic polymer.  The admixture is mixed in a first zone at a temperature above the melting point of the polymers for at least ten seconds but for less than 25% decomposition of the peroxide and then in a second zone for a period that is at least four times the half-life of the peroxide.  A grafted polymer having a melt index that is 20-100% of that of the polymer prior to grafting is obtained.  The grafted polymer may be used in a variety of end-uses, for example, the manufacture of film, moulding of articles, extrusion coating of metals and coextrusion processes.
