摘要： A method of making a heat exchanger sheet is disclosed including progressively forming an elongated flat sheet of metal into a continuously corrugated sheet having a plurality of deeply drawn convolutions which extend across the sheet, and compressing the periphery of the corrugated sheet to provide a substantially flattened edge portion while retaining a centrally disposed corrugated portion with minimal cold working thereof. Preferably, the sheet made thereby has convolutions with slightly sloping walls to better provide a geometrically uniform overlapped pattern in the flattened edge portion thereof.

摘要： Method and apparatus for filling viscous dampers in which the method comprises assembling a damper housing with an inertia weight placed loosely therewithin and a housing top having a single aperture therein and adapted to provide a complete closure for the inertia weight, placing the assembly in a vacuum chamber equipped with an electron beam welding device and means for effecting relative movement between the assembly and the electron beam welding device, and inserting a valve and fitting sealingly within said aperture with the valve in an open position, evacuating the vacuum chamber to provide a vacuum within the chamber and within the damper assembly, effecting movement between the assembly and the device to sealingly weld the top to the damper housing, closing the valve, attaching means for supplying a viscous fluid under pressure to said valve, removing the valve from the damper assembly, and welding a plug within the aperture to sealingly retain the fluid within. In its apparatus form, the invention comprises a vacuum chamber, an electron beam welding device mounted for welding within said chamber, means for positioning a viscous damper assembly within said chamber, said damper assembly comprising a damper housing and a cover therefor with an inertia weight disposed therewithin, said damper assembly also comprising a single aperture for filling the damper with a viscous fluid, means for evacuating the vacuum chamber and damper assembly disposed within, means for providing a relative movement between said assembly and said welding device for effecting a complete weld between the housing and cover, and means for filling the welded assembly through said aperture. In its preferred form, the apparatus also comprises a valve having a fitting adapted to sealingly fit in the aperture and provide communication from within the damper assembly to the vacuum chamber whereby evacuation of the chamber also evacuates a space within the assembly, and in which the valve has a closure means positioned to be actuated by the welding device upon completion of the welding operation.

摘要： Conventional apparatus for forming pressure vessels from tubing involves a separate step of the forming of the tubing into coils and then separately welding the coils together. The conventional method has proven to be costly because of the type of apparatus required as well as time consuming and frequently producing a poor quality product when the welding is done independent of coiling step. The subject apparatus overcomes these problems by providing a collapsible mandrel to which tubing is wrapped to form coils for a pressure vessel and simultaneously welding the coils together in one step. The coils are guided on the mandrel by a carriage means which is controlled by a hydraulic system to maintain the coils into intimate contact with each other as they are being welded together. A welding torch, also carried by the carriage, is guided by the forming of the coils rather than some guide means to guide the welder independently of this operation. Tension apparatus is provided which also serves as a guide for the tubing as it is being wrapped on the mandrel. The mandrel is collapsible so that its interference with a finished fabricated cylindrical wall can be reduced so the cylindrical wall can be easily removed. A hydraulic system is provided with features that allows a steady operation of the system without any interrupting jumps or jerks in the system which could create a bad weld.
摘要翻译： 用于从管道形成压力容器的常规装置包括将管形成线圈然后将线圈分开地焊接在一起的单独步骤。 传统的方法已被证明是昂贵的，因为所需设备的类型以及耗时，并且当焊接独立于卷取步骤时，经常产生质量差的产品。 本发明的装置通过提供可折叠心轴来克服这些问题，管芯被包裹以形成用于压力容器的线圈并且同时在一个步骤中将线圈焊接在一起。 线圈通过由液压系统控制的托架装置在心轴上被引导，以使线圈在被焊接在一起时彼此紧密接触。 也由托架承载的焊炬通过形成线圈来引导，而不是一些引导装置，以独立于该操作来引导焊机。 提供张紧装置，其也用作管道的引导件，因为其被包裹在心轴上。 心轴是可折叠的，因此其与完成的制造的圆柱形壁的干涉可以减小，因此可以容易地移除圆柱形壁。 液压系统具有允许系统稳定运行的特征，而不会在系统中产生不良焊缝的任何中断跳跃或跳动。

摘要： Prior art exchanger cores (10) have been expensive to produce and have too often had poorly heat conductive joining of the liquid circulating tubes (12) to the cooling fins (14). Herein, the tube (12) is fitted into holes (28) in the fins (14) with a small gap (42 or 44) between a portion (20,22) of the tube (12) and the hole (28). Solder sources (38) e.g., sheets (38) having holes (40) therethrough which generally match the holes (28) in the fins (14), are positioned between some of the fins (14) with the tubes (12) fitting in the holes (40) in the solder sheets (38). The entire assembly (50) is heated with the tubes (12) being held generally vertically. As the solder sheets (38) melt, solder flows through the gap (42 or 44) wetting not only the fin (14) above which it sits, but also lower fins (14). Capillary action leads to solder wetting the entire junction between each fin (14) and each tube (12). Good solder joints having excellent heat conducting properties are produced.

摘要： A rotatable cam disc has connected thereto linkage means for operating latch bolts. The cam disc has an arcuate cutout in the edge portion thereof defining a pair of end shoulders. A lock actuator plate is rotatable coaxially of the cam disc, and has secured thereto a post member movable within the cam disc cutout. Upon rotation of the lock plate actuator, the post member is engageable with an end shoulder of the cam disc for effecting rotation of the latter and actuation of the linkage means.
