摘要： A device for inspecting a cargo container such as a motor vehicle or freight pallet, with penetrating radiation. A source of penetrating radiation is mounted on a moveable bed, thereby allowing a beam of penetrating radiation to sweep the large container. At least one detector is also mounted on the bed, ether on the side of the source or on a boom, so that, as the beam is scanned across the container, the container and any contents of the container are characterized by transmitted or scattered radiation, or both.

摘要： A remote load controlling apparatus receives a disconnect signal on a line that is filtered and voltage limited. This disconnect signal sets a flip-flop which enables an oscillator and a solid-state switch. The enabled switch energizes a relay to disconnect the load from electric service. A counter counts the output of the enabled oscillator and provides a flip-flop reset signal after a local time delay that is determined by a particular incremented count state of the counter. The reset flip-flop disables the oscillator and solid-state switch to de-energize the relay and reconnect the load to electric service. The flip-flop may also be reset by a remote signal to disable the oscillator and solid-state switch and reconnect the load before the counter is incremented to its particular incremented count state. A second counter and a second solid-state switch may be added to ensure that the load is connected to electric service if a component of the apparatus should fail. The second solid-state switch is enabled by the pulse output of the enabled oscillator and is disabled when the oscillator stops generating pulses. The second solid-state switch is connected in series to the first solid-state switch and the relay is energized only when both solid-state switches are enabled. The second counter is provided to enable the oscillator on the leading edge of the disconnect signal and disable the oscillator after a time delay.
摘要翻译：远程负载控制装置在被滤波和电压限制的线路上接收断开信号。该断开信号设置触发器，其使能振荡器和固态开关。启用的开关为继电器通电，以将负载与电气服务断开。计数器对使能振荡器的输出进行计数，并在由计数器的特定递增计数状态确定的本地时间延迟之后提供触发器复位信号。复位触发器禁用振荡器和固态开关，使继电器断电并将负载重新连接到电力服务。触发器也可能被远程信号复位，以禁用振荡器和固态开关，并在计数器增加到其特定递增计数状态之前重新连接负载。可以添加第二计数器和第二固态开关，以确保如果装置的部件失效，负载被连接到电力服务。第二个固态开关由使能振荡器的脉冲输出使能，当振荡器停止产生脉冲时禁止。第二固态开关与第一固态开关串联连接，只有当两个固态开关都使能时，继电器才通电。提供第二个计数器，使振荡器能够在断开信号的前沿，并在时间延迟之后禁用振荡器。

摘要： A CT scanner having a rotating X-ray source and a stationary circular array of 600 contiguous detectors includes a sliding shutter mechanism incorporated in the precollimator system that prevents detectors at the beginning and at the end of a scan from receiving radiation while progressively increasing and decreasing, respectively, the current to the X-ray tube.

摘要： The detection of malignant or dysplastic cells in a tissue sample, by treating the sample with a solution containing radioactive gallium and relying upon the greater take-up of the gallium by the malignant or dysplastic cells relative to normal cells to provide a detectable signal of malignancy, is improved by including non-radioactive preemptive species in the solution to pre-empt potential gallium binding sites in protein molecules of normal cells. The pre-emptive species may be one or more of scandium, indium or yttrium.

摘要： An X-ray inspection system includes a circuit that responds to a high level of opacity for more than a predetermined time interval by providing an alarm signal to alert the inspector of the possibility of concealed contraband. The circuitry also provides a pulse when exceptional opacity is detected for combination with the vertical deflection signal to translate the display of exceptionally opaque objects to a different portion of the viewing screen to facilitate identification of potential contraband without opening the baggage or parcel being inspected.

摘要： A remote meter-reading system interrogates meter stations over power lines and receives encoded meter readings over the power lines in synchronism with the power line frequency by superimposing a digitally modulated signal over the 60-Hz power frequency. The central control station transmits at a data rate of 60-baud and receives at a data rate that is 60-baud or a submultiple thereof, to reduce the demands on the remote meter station transceiver as compared to those on the central control unit transceiver. The bit clock at the central control unit and the meter stations is derived from the 60-Hz power line phase available at each station. Each meter station achieves message synchronization by continuously monitoring the data bit stream for a preset synchronization code and thereafter treats the following 21 data bits as address and function codes. Each meter station that is addressed responds at the data rate designated by the function code by transmitting with a message including the address and function bits for comparison at the central control station with that originally sent to facilitate error detection, and the meter reading encoded according to an error detecting code. A binary data bit is represented by quadrature phase lead and lag relative to reference phase of the character.
