摘要： An ultrasonic flaw detector for detecting irregularities in an object, such as a pipe (10), having a segment of annular cross-section. The detector includes a transducer (20) with an involute transmitting surface (116) for sending ultrasonic signals into the object at equal non-radial angles of incidence. The detector further includes transmission apparatus (122) for maintaining a constant physical relationship between the transducer (20) and the pipe and interpretive apparatus (300) for correlating reflections of ultrasonic signals within the object with irregularities.

摘要： A mounting system for maintaining a transducer (20) in contact with a pipe (12) during testing. The system is mounted to a frame (32) which is in turn mounted for movement along a length of pipe. A first step in the testing procedure is to position the frame (32) a distance away from the pipe dependent on the pipe diameter. A carriage (34) coupled to the frame is then lowered to a scanning position and scanning takes place as the frame is moved along the pipe. A universal joint mechanism (36) connecting the carriage to the transducer (20) allow up and down and side to side movement of the transducer and thereby allows scanning to continue on pipes with bows and other irregularities along their length. When the pipe end is neared the carriage (34) is retracted away from the pipe (12) by action of a spring mechanism (154). In this retracted position downward movement of the transducer is prevented by a ball support (146, 147) coupled to the transducer and contacting a supporting surface (149) of the carriage. In this way the transducer will not fall from the pipe's end nor collide with the end so that damage to both transducer and mount are avoided.

摘要： High lead content of uniformly dispersed finely divided particles is obtained in cast steel through a programmed addition of lead to molten steel in a vessel and control of other process factors, such as temperature, agitation and slag cover, affecting dissolution and retention of lead in molten steel. In the addition of lead, an initial quantity is introduced to the steel, large with respect to the time during which it is added as compared with the total lead added relative to the total time span of lead addition, and subsequently additional led is added, the total sufficient to produce a lead content in the steel greater than 0.15 percent by weight and no greater than 0.26 percent by weight. Preferably the total lead is introduced as three to five discrete additions at time intervals of one to fifteen minutes.

摘要： A crane structure comprising a trolley, a beam member which is suspended from the trolley by flexible cables, a hoist on the trolley for changing the elevation of the beam, and a pair of hook assemblies. The beam is constructed to provide cam portions adjacent bearing seats so that the hook assemblies are guided from one bearing seat to another when the beam is lowered until the weight of the hook assembly is supported by a surface beneath them. A hook assembly stabilizing mechanism is also provided. The disclosure also includes a novel laminated hook construction which establishes line contact with a support which line forms a pivot axis for hook adjustment.

摘要： THE PROCESS DISCLOSED HEREIN COMPRISES THE PROCESS OF CEMENTING OR PRECIPITATING NICKEL FROM A SOLUTION CONTAINING NICKEL SALTS BY THE ADDITION OF IRON PARTICLES UNDER AN OVERPRESSURE OF AT LEAST 35 P.S.I.G., PREFERABLY AT LEAST 60 P.S.I.G., AND AT A TEMPERATURE OF AT LEAST 60* AND LESS THAN 100*C. THE IRON PARTICLES PREFERABLY HAVE A THIN COATING OF COPPER THEREON. THE USE OF OVERPRESSURE PERMITS A LOWER TEMPERATURE TO BE USED IN THE RECOVERY PROCESS, FAVORS MORE COMPLETE CEMENTATION OF THE NICKEL THAN WITHOUT THE OVERPRESSURE, AND RESULTS IN A LOWER SULFUR CONTENT IN THE CEMENTED METAL SO THAT THE PRODUCT MAY BE USED DIRECTLY IN ALLOYING FURNACES WITHOUT A PRIOR ROASTING STEP TO REDUCE THE SULFUR CONTENT.

摘要： The output of a radioactive source is directed through a moving stream of granular material, e.g., coal on a conveyor, and the radiation passing through is sensed by a detector. The detector generates a pulse signal of which the pulse repetition rate varies with the radiation sensed. The pulses generated are counted in a binary counter, and a timer periodically initiates a read-out of and resets the counter to effect successive counting cycles, whereupon the digital count in each cycle is converted to an analog voltage, the magnitude of which is recorded in terms of bulk density of the coal. The recorder controls the addition of water or oil to the coal to, respectively, lower or increase the bulk density of the coal. Controls are included which guard the system from misperforming when a supply of coal has failed, when the depth of coal on the conveyor belt has been lost, and when the coal is so dense that an application of water is required.
摘要翻译：放射源的输出通过移动的粒状材料流引导，例如在输送机上的煤，并且由检测器感测通过的辐射。检测器产生脉冲重复频率随感测辐射而变化的脉冲信号。产生的脉冲在二进制计数器中进行计数，并且定时器周期性地启动计数器的读出和复位以实现连续的计数循环，于是每个周期中的数字计数被转换成模拟电压，其幅度被记录在煤的堆积密度方面。记录器控制向煤中添加水或油分别降低或增加煤的堆积密度。包括控制装置，当煤炭供应失败时，当输送带上的煤深度已经消失，以及煤如此密集以至需要施加水时，防止系统失控。

摘要： Vaporizing apparatus and method for the vaporization of metal for vacuum deposition. A relatively thin shell of liquid metal to be vaporized is provided such as through inner and outer concentric vessels which communicate with each other. The thin shell of liquid is heated and boils and evaporates to provide metal for vaporization. The thin shell of liquid is generally formed within the space between the inner and outer concentric vessels. The space within the inner vessel contains liquid which is typically molten but substantially non-boiling. The boiling shell of liquid fills the space between the inner and outer containers so as to provide substantially constant volume of metal for vaporization. Baffle means are provided for removing droplets of liquid normally from within the vapor.
