Title: Method of and device for inspecting and or controlling electron beam welded joints
IPC: B23K15/02
Filed: 1970-05-01
Abstract: 1309772 Testing welded joints electrically K H STEIGERWALD 1 May 1970 [6 May 1969] 21021/70 Headings G1N and G1A [Also in Divisions B3 and H4] In electron-beam welding a joint between workpieces, the values of a parameter occurring in the area of the joint being produced are measured during the welding process to give an indication of the joint quality. IN ONE EMBODIMENT temperature-sensitive elements are disposed about the joint, and measurements therefrom are used as an indication of the quality of the joint and to exert a control function on the apparatus effecting the weld. The measurements can be compared, for this purpose, with known optimum values. Should the welding energy diverge from the joint at any point along its length or depth Figs. 1-14, (not shown), a temperature gradient will exist between some of the detector elements on opposite sides of the joint. A number of arrangements of detector elements are described: they can be arranged both externally and internally of the workpieces, or on the upper and/or lower surfaces; the elements can be arranged to be stationary relative to the workpieces, or to move therealong during welding Fig. 20, (not shown). IN A PRACTICAL CONSTRUCTION (Fig. 21), the workpieces, 2, 4 are supported on apparatus which corrects the position of the joint relative to the electron-beam 78, in response to measurements from banks of detectors E11-E15, E21-E25, E31-E35, E41-E45, arranged on both sides of the joint along both workpiece surfaces. The workpieces can be tilted about axis 90 (which lies along the joint upper part), by motor M2, shifted axially by motor M1 and shifted laterally by motor M3. The apparatus includes amplifiers V1-V8 whose responses are used to control the various motors. In instances where the measurements relayed by these amplifiers are compared with previously-obtained optimum condition measurements, a programme generator comprising feelers and cam discs supply amplifiers V11-V14 is used to provide error signals which can be used to control the motors or reject workpieces. IN A MODIFICATION (Fig. 22) an infra-red image system 138 projects an image 2', 4' of the workpieces 2, 4 in the evacuated chamber 136 of the electron-beam welding device, on to image screen 142. The brightness of an image point corresponds to the temperature of the associated workpiece point. Photo-electric cells are moved along the image screen, giving indications of the workpiece temperature distribution as welding progresses. IN A FURTHER EMBODIMENT (Fig. 25) a signal generator 260 producing an alternating magnetic field, and hence circulating currents in the workpieces, is used. Detectors 262-268 can be stationary or moved during welding. The magnetic field distribution can be obtained and displayed on an oscilloscope by using an additional detector which sweeps transversely of the joint.

Title: Improvements in galvanic batteries
IPC: H01M10/18
Filed: 1926-08-26
Abstract: 281,018. Lewis, A. Aug. 26, 1926. Cells; electrodes; gas exits. - A bipolar secondary battery is made by moulding the material of the cell wall round the bipolar plates. In the form shown in Fig. 3, the cell 11 is moulded round the plates 10, and these are formed of a middle layer 10<a> of lead-antimony alloy or other impenetrable and inert electrical conductor and two outer layers 10<b> of lead which are provided with pockets 13 for paste or are otherwise formed in any usual manner. In an alternative, plates of lead-antimony alloy are used. A vent-tube 14 is provided for each cell, the tops being closed by rubber rings 17 extending round the container. To the top of each plate 10 is secured a short cylindrical extension over which fits a socket 15 to which is secured a wanderplug socket 16. The upper edges of the plates, the vent-tubes and the sockets are embedded in the top of the container. The battery is enclosed in an outer case 18 of wood, ebonite &c. The moulding operation may be effected by standing the plates suitably held apart on edge in molten paraffin wax, or by inserting the plates in grooves in the outer case and pouring paraffin wax between them, or in a third method, the grooves in the plates are omitted. Pitch or a solution of celluloid may be used instead of molten wax.

Abstract: 755,297. Hatch covers. MERCIER, J. G. July 27, 1954, No. 21930/54. Addition to 698,798. Class 113. In a sealing arrangement for hatch covers having one or more panels 14, 15 and comprising a strip or strips of resilient material 24 disposed to form a continuous liquid seal between the panel or panels and the coaming 5 or adjacent panels, means are provided to collect and discharge liquid which may leak through the seal. The coaming 5 has an angle member 7 with a plate 8 defining a channel 9 in which leakage liquid collects and is discharged through a pipe 10. The sealing strip 24 is retained in flanges 11 and 12 forming a continuous channel 18, 19, 20, 21, 22, 23 (Fig. 6). The flange 11 abuts the plate 8 to prevent the sealing strip being compressed beyond a predetermined amount and also protects the sealing strip against lateral pressure. A gutter member 25 mounted on the inclined end 17 of panel 15 collects any liquid which leaks through the seal between the panels and discharges it at either or both ends into the channel 9. In another embodiment the cover comprises a single panel hinged to the coaming, the sealing strip and its channels forming a rectangle in one horizontal plane. In another embodiment comprising panels which may be pivotally connected together, the end faces 16, 17 of adjacent panels and the portions 18 and 22 of the continuous sealing member channel are vertical. A metal plate is carried by one of the adjacent panels so as to extend over the gap therebetween to protect the strips forming a liquid seal between said adjacent panels.
