Granted: 1997-06-25
Abstract: A hand-held gamma radiation probe (12) is employed to locate radiation concentrations in animal tissue in conjunction with a control function providing an enhanced audio output particularly suited for curing the user as to source position. The probe (12) is positioned at a location on the animal body representing background radiation and a squelch low count rate is developed therefrom. The squelch low count rate is multiplied by a range factor to develop a squelch high count rate and frequencies are developed from a lock-up frequency table from lowest to highest in correspondance with the developed high and low squelch count rates. Slew rate limiting of the count rates is provided by development of a squelch delta value representing the difference between the squelch high and low count rates divided by a time element. Selection of frequencies for audio output from the frequency table is limited by the value of the squelch delta value. A weighting of received radiation counts is carried out continuously to develop count rate values used by the system.

Title: Non-tin-based low toxicity anti-fouling agents
Inventor: DICK RICHARD J
IPC: C09D5/16
Filed: 1989-12-20
Granted: 1998-08-01
Abstract: Disclosed are marine anti-fouling compositions, such as coating compositions, of a thermoplastic or thermoset binder, solvent, and anti-fouling agent wherein the anti-fouling agent comprises a pesticide or herbicide having a  chi  value of between about 0.01 and 0.5, a Z parameter for vinyl or aromatic compounds of between about 0.01 and 0.08, and an LD50 value of greater than 200 mg/kg against rats and mice.

Abstract: 본 발명은 자동차 차체요소의 돌출연단에 탄성재료로 둘러싸인 금속 프레임이 포함된 U자형 단면의 섹션을 장착시키는 방법에 관한 것으로서, 이러한 프레임은 코팅재료의 물리적 작용하에 있는 동안 거의 변형되지 아니한다. 
     본 발명에 있어서는 장착대상 차체요소(2)의 길이와 거의 같은 섹션의 길이를 이용하고, 처음에는 섹션의 예정된, 경우에 따라서는 눈금으로 표시된 부분을 차체요소의 가장자리중 예정된, 경우에 따라서는 눈금으로 표시된 위치(4)에 장착시키고, 이어서 교호적 충격운동을 제공하는 연질헤드가 달린 진동식 나무망치(7)을 이용하여 전술한 예정위치(4)로부터 섹션의 제1단부까지, 그 다음에는 언제나 예정위치로 부터 섹션의 또 다른 단부까지 차체요소의 가장자리에 섹션을 연속적으로 부착시킨다.
