摘要： An oceanographic sampling bottle providing low drag for a rapid descent rate and low susceptibility to leakage after sample acquisition. The sampling bottle comprises streamlined inlet and outlet valve members shaped and positioned to avoid flow separation. The bottle with valves occupies a relatively small cross-sectional area facilitating design of a rosette or cluster of bottles. A hollow resilient conduit interconnecting the inlet and outlet valves draws the valves against seats on the sampling bottle when released. Vents in the conduit provide pressure equalization.

摘要： The antenna feed includes a waveguide radiator with a conductive flange positioned about the waveguide near its radiating end. The flange includes one or more corrugations which each have tapered walls and which is truncated at its root and crest by a flat or curved plane. The corrugations thus may have a trapezoidal cross-section or a curved root and crest cross-section. The curvature may be sinusoidal.

摘要： Two new compounds which are attractive to male fall cankerworm moths, Alsophila pometaria, in the field, are described. They are (Z,Z,Z,E)-3,6,9,11-nonadecatetraene and (Z,Z,Z,Z)-3,6,9,11-nonadecatetraene. These compounds, separately and together, and these two compounds together with a third, [(Z,Z,Z)3,6,9-nonadecatriene], act as attractants to male fall cankerworm moths and can be used to monitor, confuse or attempt to control, populations of the moths.

摘要： An improved railroad stub switch is described in which the axial rail tension or compression forces due to temperature fluctuations are transmitted through the switch by means of radius arms connected to both the switch and fixed rails, thereby eliminating the need for expensive expansion joints at the switch. In a preferred embodiment, interlocking point shoes are also employed so as to hold the butt ends in vertical and horizontal register and transmit a signal to the trailing side rail of the impending approach of a load from the approach side rail, thereby reducing batter on the trailing side rail.

摘要： The apparatus for analyzing the surface of a fibrous web, such as a paper or a textile, includes a prism structure in which one surface is placed in contact with the fibrous web under a predetermined pressure. A collimated beam of light is directed into the prism on the contact surface. The light reflected from the contact surface through the prism is directed to a detector. The detector senses the light reflected by the contact surface as well as the light diffracted at the contact surface to indicate the surface condition of the fibrous web.

摘要： The UV radiation triggered rail-gap switch applies a high voltage from a low impedance source to a low impedance load. The switch includes first and second parallel elongated electrodes spaced to form a uniform gap along their length. The first electrode is adapted to be connected to the high voltage source, while the second electrode is adapted to be connected to the low impedance load. When a voltage from the source is applied to the electrodes, one electrode will be positive relative to the other electrode. In addition, the cross-section of each of the electrodes is sufficiently smooth to prevent points of high field concentration between the electrode. This cross-section is defined by the field enhancement factor of each electrode which is preferably less than 1.5. The switch also includes an enclosure in which the electrodes are located and which contains a gas mixture for maintaining the breakdown threshold between the electrodes. A preferred gas mixture includes Ar, N.sub.2, and SF.sub.6 at a gas pressure selected to prevent breakdown in the switch until triggered by a UV radiation source. The UV radiation source directs a beam of radiation substantially parallel to the pair of electrodes, preferably near the positive electrode, for initiating multi-channel, sub-nanosecond jitter, breakdown in the gap between the electrodes. The UV radiation may be obtained from either an incoherent radiation source or an UV laser source, but should be of short duration in the form of a narrow beam which is uniform along its cross-section.
摘要翻译：紫外线辐射触发的轨距开关将高电压从低阻抗源施加到低阻抗负载。该开关包括间隔开以沿其长度形成均匀间隙的第一和第二平行细长电极。第一电极适于连接到高电压源，而第二电极适于连接到低阻抗负载。当来自源极的电压施加到电极时，一个电极将相对于另一个电极为正。此外，每个电极的横截面足够平滑以防止电极之间的高场浓度点。该横截面由每个电极的场增强因子限定，优选小于1.5。开关还包括其中电极位于其中并且包含用于维持电极之间的击穿阈值的气体混合物的外壳。优选的气体混合物包括Ar，N 2和SF 6，气体压力被选择以防止开关中的击穿，直到由UV辐射源触发。 UV辐射源引导基本上平行于该对电极的放射线束，优选在正电极附近，用于引发电极之间的间隙中的多通道亚纳秒抖动。 UV辐射可以从非相干辐射源或UV激光源获得，但是应该是沿其横截面均匀的窄光束形式的短持续时间。

摘要： A vacuum coating vessel is provided comprising a casing having a vacuum coating compartment separated from a vapor source compartment by a partition having vapor ports. A slidable shutter plate is provided on the vapor source compartment side of the partition. The shutter plate, in an open position, aligns vapor ports therein with the ones in the partition, and, in a closed, closes the vapor ports with `O`-ring seals. A mechanism is provided for moving the shutter plate away from and then towards the partition at the beginning and end respectively of each stroke to avoid scraping the `O`-rings and to ensure that the `O`-rings are kept as clean as possible. The vapor ports of the shutter plate and the partition are chamfered away from the vapor source compartment so that the `O`-ring sealing surfaces around the vapor ports in the partition are masked when the shutter plate is in the open position. When two or more vapor ports are provided, the length of stroke of the shutter plate is reduced by arranging the vapor ports at an angle of about 45.degree. across the direction of travel of the shutter plate so that the length of stroke is only that required for a single port. It should be noted that vapor actually passes through vapor ports in the shutter plate, while in conventional gate valves vapor passes directly through an opening in the casing when the valve plate is slid to the open position.
摘要翻译：提供真空包衣容器，其包括壳体，该壳体具有通过具有蒸气端口的隔板与蒸气源室隔开的真空涂层室。在隔板的蒸汽源室侧设置有可滑动的挡板。快门板处于打开位置，使其中的蒸气端口与分隔件中的蒸气端口对齐，并且在闭合状态下，以“O形环密封件”封闭蒸气端口。提供了一种机构，用于在每个行程的开始和结束时将闸板移动离开分隔板，然后分开，以避免刮擦“O形圈”并确保“O形圈尽可能保持清洁。挡板和分隔件的蒸气端口与蒸气源室隔开，使得当挡板处于打开位置时，分隔件周围的蒸气端口周围的“O”形密封表面被遮蔽。当设置两个或更多个蒸汽端口时，通过将蒸气端口沿着挡板的行进方向布置在大约45度的角度来减小闸板的行程长度，使得行程长度仅仅是所需的用于单个端口。应该注意的是，蒸气实际上通过挡板中的蒸气端口，而在常规的闸阀中，当阀板滑动到打开位置时，蒸气直接通过壳体中的开口。

摘要： Polysulfone cast films, including polyethersulfone cast films, are partially gelled with mineral acid prior to or during the conventional water gelation to control the porosity of and improve the productivity of reverse osmosis and ultrafiltration membranes thus produced. The partial gelation may be carried out prior to the water gelation by contacting the cast film with the mineral acid in a gaseous or aqueous form and the gaseous form may be diluted with air. The partial gelation may, in different embodiments, be carried out simultaneously with the conventional gelation by dissolving the mineral acid in the gelation liquid.
