Title: Improvements in means for indicating the level of liquids
IPC: G01F23/16
Filed: 1927-01-29
Abstract: 291,128. Hatfield, H. S. Jan. 29, 1927. No Patent granted (Sealing fee not paid). Indicators actuated by pressure of head of liquid. -In a liquid level indicator applicable to petrol tanks, the pressure is measured at a point in the suction pipe through which the liquid is withdrawn, the gauge being connected by a pipe having a small air leak, and an enlargement near the junction with the suction pipe. A small chamber 3 is connected to the suction pipe 2, and to a suction gauge 5 which indicates the height of the liquid in the chamber 3 above the level in the tank. A small amount of liquid enters the chamber 3 when suction is applied, but afterwards varies little in level. Any loss of air may be replaced by a porous plug 6 or by providing the union of the pipe 4 with a porous washer. The chamber 3 may be replaced by a horizontal coil of piping, so that the liquid level in it does not vary although the surface may move. In another modification (Fig. 4, not shown) an additional tube may connect the chamber 3 with the tank, in cases where the suction pipe has a non-return valve at its' lower end. A liquid manometer may be used in place of the gauge.

Title: A process for stabilising ª-caprolactam
Filed: 1957-01-25
Abstract: e -Caprolactum, which has been distilled and is in the form of a melt or aqueous solution with a water content not exceeding 5 per cent of the weight of the caprolactam, is stabilized by adding thereto an alkali metal base, an alkaline earth metal base or an aliphatic nitrogen base, or a salt of one of these bases with a weak inorganic or organic acid, which salt has an alkaline reaction in aqueous solution, or a mixture of such compounds, the proportion of the stabilizing compounds being 0.001 to 2 per cent by weight, based on the weight of the e -caprolactam, and the water content of the resulting stabilized e -caprolactam not exceeding 5 per cent by weight.  Suitable stabilizing compounds are alkali metal hydroxides or alkaline earth metal hydroxides, alkali metal carbonates, cyanides, borates, or phosphates, alkali metal or alkaline earth metal acetates, a ,o -diamines or their methylation products and their adipates, especially hexamethylene diamine, tetramethyl hexamethylene diamine and ethanolamines. The addition of these stabilizing compounds prevents deterioration of the e -caprolactam during transport or storage, in spite of the use of temperatures between 60 DEG  and 100 DEG  C. and even when there is access of oxygen from the air.  The stabilizing compound may be added to the molten caprolactam before it is placed in containers, or to ensure good mixing, the compound may be dissolved in a small proportion of water and the resulting aqueous solution added to the molten caprolactam.  In addition, a protective gas, such as oxygen-free nitrogen, may be used to exclude air.  Examples show the amounts of volatile bases contained, after storage, with access of air, in e -caprolactam stabilized with sodium hydroxide, sodium carbonate, sodium borate, lithium acetate, hexamethylene diamine, tetramethyl hexamethylene diamine or a mixture of sodium borate and lithium acetate.  Comparative examples describe the storage of caprolactam without the addition of the stabilizers under similar conditions.
