摘要： 527,212. Mercury switches. ADLAKE CO. April 4, 1939, No. 10489. Convention date, April 14,1938. [Class 38 (v)] In a mercury switch in which change in the level of the mercury, produced, e.g., by the movement of an electromagnetically-operated displacer 46, causes mercury to bridge two electrodes 32, 33, the electrodes are mounted in a cup 39 having a small hole 45 through which mercury passes to cause a slow " make " or "break." In the form shown, energization of a magnet 26 raises the displacer 46 and mercury slowly passes out of the cup 39 through the hole 45 till the surface reaches an insulating sleeve 36 and the circuit between electrodes 32, 33 is broken. On de-energization of the magnet 26 the displacer 46 moves back and causes mercury to rise outside the cup 39 and flow over the slanting upper edge of the cup thus causing a quick " make." By using a smaller quantity of mercury, mercury could only enter the cup through the hole 45 and thus there would be a slow " make " as well as a slow " break." In a modification, Figs. 8, 9 (not shown), energization of the magnet lowers the displacer and so causes the " make" while de-energization causes the " break." In another modification, Fig. 11, a slow make of say 6 secs. is produced by the mercury entering the hole 45 in the manner described above, the gas escaping from inside the cup through a porous plug 62 and mercury trap 64. 'A very slow break of say three minutes is produced by the gas being able to gain re-admittance to the cup only through a dense porous sleeve 63 and the plug 62 and thus preventing the mercury escaping through the hole 45 at the rate it would otherwise do. The gas used to fill the switch envelope may include hydrogen and helium.

摘要： 517,730. Mercury switches. BURGESS, A. F. (Adlake Co.). July 1, 1938, No. 19517. [Class 38 (v)] Inside a glass envelope 10 holding mercury 15 is disposed a displacer 16 of glass or quartz carrying a ferro-magnetic armature 17 fixed to it by springs 19 which also act as buffers and which has guide projections 22. The switch is held between poles 23, 24 of an electromagnet which when energized, pulls down the displacer 16 to cause the mercury to bridge contacts 11, 12 made of tungsten, molybdenum or tantalum. To prevent the deleterious effects of current carrying iron on the mercury, the armature 17 and any other parts of ferromagnetic material within the switch are coated with an oxide of iron by being heated in a stream of oxygen or by the Bower- Barff or Russia oxidising processes.

摘要： 475,267. Mercury switches. BURGESS, A. F. (Adlake Co.) April 15, 1936, No. 10839. [Class 38 (v)] In a switch in which energization of a coil 26 attracts a member 19 causing variation in the level of mercury 18 and consequent closing or opening of circuits, the lead 13 is arranged in a protuding portion 25 of the container. The member 19 consists of an outer magnetic tube 21 and an inner glass thimble 20 which are held together by fingers 23 on the tube 21 engaging between the coils of a spring 22 arranged on the end of the thimble 20. The spring 22 besides acting as a buffer serves as a screw thread enabling the longitudinal position of the tube 21 to be adjusted relatively to the thimble 20. In the form shown, circuit is closed between two leads 11, 13. Raising the displacer 19 causes the mercury to leave the lead 13 and subsequently engage the lead 12. The thimble in its lower position rests on a coil spring 33. In a modification, Fig. 7, the thimble has an enlarged portion 39 causing a relatively quick make and break. For alternating current the sleeve 21 is of cold rolled steel case-hardened and ground. For direct current it is of soft iron and then preferably is provided with a guide washer 35 of tool steel with projecting lugs. Specifications 428,514, 428,652, and 433,740 are referred to.

摘要： 433,773. Mercury switches; electromagnetic switches. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Adlake Co. ; 319, West Ontario Street, Chicago, U.S.A.) June 27, 1934, No. 14618/35. Divided out of 433,740. Drawings to Specification. [Class 38 (v)] In a mercury switch in which circuit is made and broken by the displacement of the mercury by a magnetically operated plunger, the plunger consists of telescoping magnetic and refractory members one of which projects beyond the other to receive springs which hold the members in fixed relation and also act as buffers. The switch described is the same as that described in Specification 433,740.
