摘要:
Disclosed are compositions comprised of (a)a polymer containing pendant and/or functional groups selected from the group consisting of carbamate, urethane and/or amide functional groups; and (b) a rheology modifier comprising the reaction product of an amine and an isocyanate; and, optionally, a polymer which is different from the polymer (a) which contains carbamate, urethane and/or amide functional groups. Also disclosed are curable compositions comprised of the compositions described above which further comprise (c) a curing agent having functional groups reactive with the functional groups of the polymer (a). The curable compositions are useful for a variety of applications such as adhesives, sealants and surface coatings where the presence of a carbamate, urethane and/or amide functional polymer in conjunction with the rheology modifier provides improved thixotropy and superior sag resistance.

摘要:
To encode an analog to digital signal, a comparator compares an input analog signal with a reconstructed negative feedback analog signal and provides a comparison output digital bit for each comparison. A number of output digital bits is stored in a clocked shift register. A coincidence detector is coupled to the register and provides an output pulse when all the bits in the register are the same. A proportional coincidence integrator proportionally amplifies and integrates the coincidence detector output pulses. A slope polarity switch is coupled to the output of the integrator and to the first bit in the shift register and applies a polarity sign to the integrator output according to the bit value from the register. The output of the switch is integrated to form the reconstructed negative feedback analog signal which is coupled to the comparator for comparison with the input analog signal. The digital output is taken from the shift register first bit. To decode a digital to analog signal, the above circuit is used. The digital signal is applied directly to the input of the shift register, the comparator not being used for decoding. The output analog signal is the integrated output from the polarity switch.

摘要:
Two different frequencies are generated within an interrogation zone. The receiver portion of the system determines the presence of a predetermined marker tag within the interrogation zone by the sensing and processing of a ratio of sideband signals generated by the interaction of the two different frequencies and the predetermined marker tag. The system is greatly immuned to false alarms due to the method of processing the sensed sideband signals. Falsely generated signals are nulled and subtracted out in the receiver portion of the detection system.
