Abstract: A phase detector for controlling a phase locked loop having a voltage controlled oscillator. A counter is clocked by a clock signal produced by the voltage controlled oscillator. A latch coupled to the counter is clocked by a modulated clock signal to latch values output by the counter. The modulated clock signal is produced by a phase modulator which modulates a synchronization clock reference signal. An accumulator coupled to the latch and clocked by the modulated clock signal receives and averages the latch values to produce a phase error signal representative of phase difference between the voltage controlled oscillator clock signal and the synchronization clock reference signal.      The phase error signal is coupled to the voltage controlled oscillator to reduce the phase difference. The phase modulator modulates a rising edge of the synchronization clock reference signal with a modulation signal having modulation frequencies outside the loop bandwidth of the phase locked loop. The modulation signal is a discrete step signal having a fine time resolution which causes the latch to latch different values output by the counter in different time intervals corresponding to the time of occurrence of the modulated clock signal's rising edge with respect to the respective time intervals.

Abstract: Balloon especially useful for dilatation of gastrointestinal lesions has a burst pressure of at least 9 atmospheres, a diameter at 3 atmospheres of about 5 mm or more, and an average compliance over the range of from 3 atmospheres to burst of at least 3 % per atmosphere. Such balloons and balloons having other combinations of burst strength, compliance and diameter may be prepared by a method wherein a tubing of a thermoplastic polymer material is radially expanded under a first elevated pressure at an elevated temperature to form the balloon at a first diameter and then annealing the balloon at a second elevated temperature and a second pressure less than the first elevated pressure for a time sufficient to shrink the formed balloon to a second diameter less than the first diameter. The thermoplastic polymer material may be a block copolymer material. Catheters bearing balloons prepared by this method have low withdrawal force requirements, especially catheters used in through-the-scope applications.

Abstract: A method for producting a chewing gum with a controlled release of a bitterness inhibitor, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the bitterness inhibitor by coating and drying. The bitterness inhibitor is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated bitterness inhibitor is preferably then co-dried and particle sized to produce release-modified bitterness inhibitor for use in chewing gum. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed. The preferred bitterness inhibitor is sodium gluconate.

Abstract: A continuously variable load responsive brake pressure control valve controls the amount of brake pipe pressure for a railway vehicle. The system also includes means for isolating the load sensing means from transient inputs caused by normal vehicle motion. A  spring loaded isolator coupled with a matched hydraulic cylinder isolate wheel truck deflections with respect to the car body, preventing erroneous inputs to the load sensor of the variable load braking system so as to provide more accurate brake cylinder pressure according to vehicle load weight. The variable load limiting valve is continuously operable between an empty vehicle condition and a fully loaded vehicle condition and assures a minimum braking pressure, while also helping prevent sticking of the brakes.
