Abstract: There is disclosed a ballistic joule meter containing an absorber having a sufficiently low absorption factor that energy is transmitted beyond the face of the absorber and is absorbed throughout the volume thereof. The temperature rise due to the absorption of the pulse of radiation is measured by a thin wire electrical resistance thermometer. In order to cancel out ambient effects a reference absorber is also provided in the apparatus which is not exposed to the incident radiation and the energy is measured by measuring the temperature difference between the reference and operative absorber the temperature difference being measured with a bridge circuit.

Abstract: The antenna structure disclosed is of the discone type and comprises six support towers arranged at the vertices of a hexagon. Active element supporting cables extend between the towers along the sides of the hexagon. A plurality of active elements radiate outwardly from a feed point located centrally of the hexagon to terminate on the supporting cables. The supporting towers are guyed by a plurality of guys anchored at six anchor points located on lines of intersection of vertical planes through the supporting cables. The guys extend outwardly of the hexagon within these vertical planes. The supporting tower and guying arrangement is extremely simple compared to prior arrangements. Furthermore, the feed point is supported above a platform raised above actual ground level and a plurality of ground wires extend radially outward of the platform and downwardly therefrom with the major portion of their length being buried beneath the ground. This eliminates problems of high frequency noise adjacent actual ground level and also eliminates problems of wind blown refuse, snow, etc., interfering with proper operation of the antenna. The antenna may be tuned by adjusting the height of the feed point above the platform and by means of a variable capacitor in the feed line to the antenna.

Abstract: BATTERY CHARGING CIRCUITS USING A COULOMETER IN SERIES WITH THE BATTERY TO SENSE THE AMOUNT OF CHARGE GOING INTO OR OUT OF THE BATTERY. THE COULOMETER PROVIDES AN ABRUPT RISE IN VOLTAGE UPON PASSAGE OF A PREDETERMINED NET AMOUNT OF CHARGE THERETHROUGH, E.G. WHEN THE BATTERY HAS BEEN FULLY CHARGED. THIS VOLTAGE ACTUATES MEANS TO TERMINATE FURTHER CHARGING EITHER BY TRIPPING A RELAY OR DEACTIVATING A UNIJUNCTION OSCILLATOR WHICH NORMALLY PROVIDES GATING PULSES TO AN SCR IN SERIES WITH THE BATTERY AND COULOMETER. MEANS ARE PROVIDED FOR CAUSING A TIMED OVERCHARGE OR AN INTERMITTENT PULSE TYPE OF OVERCHARGE.

Abstract: This application discloses a system for transferring loads laterally between two ships at sea. It makes use of a modification of the known ''''high line'''' wire which carries a traveller supporting the load and is moved to and fro by ''''outhaul'''' and ''''inhaul'''' wires attached to the traveller. In the modification, a single cable is used which acts as the high wire and returns round a pulley as the ''''low wire'''' being anchored at the traveller. The low wire can be divided at the traveller if desired. The ''''loose'''' end of the lower wire is wound on a winch which serves to transfer the load. The geometry of the wires at the traveller tends to keep the load at a constant distance above the water despite relative movements of the two ships.
Abstract translation: 本申请公开了一种用于在两艘海上船舶之间横向传输载荷的系统。 它利用已知的“高线”线的修改，其带有支撑负载的旅行者，并且通过附接到旅行者的“大修”和“通勤”线来回移动。 在该修改中，使用单个电缆作为高电线，并且随着“低电线”被锚定在旅行者处，轮回到滑轮上。 如果需要，低线可以在旅行者处划分。 下线的“松动”端卷绕在用于传递负载的绞盘上。 尽管两艘船的相对运动，但是在旅行者处的电线的几何形状往往会将负载保持在水平面上恒定的距离。
