Title: Improvements in processes and apparatus for the cooling of annealed goods in cooled vessels
IPC: C21D1/84
Filed: 1930-04-24
Abstract: 352,586. Annealing. PRœFERT, H., 27, Mauerstrasse, Hohenlimburg, Westphalia, Germany. April 24, 1930, No. 12690. [Class 72.] In apparatus for cooling annealed material in which the charge is protected from the exterior atmosphere by a cover dipping into the cooling liquid, the cover comprises a bell of such capacity that sufficient neutral gas mixture may be present during cooling to prevent vacuum formation and the consequent sucking in of the cooling liquid. The annealed material a is inserted in a cylindrical receptacle b weighted at f and immersed in a non-inflammable sealing liquid d contained in an outer receptacle c. A watercooled coil e round the receptacle b prevents the boiling of the liquid. A bell g is placed over the receptacle b and the oxygen present extracted by means of a combustible substance added to the charge just before the introduction of the bell. The extraction of oxygen causes a sinking of the bell followed by a rising as the neutral gas mixture is heated by the charge. Openings i at the lower edge of the bell provide an outlet for the expanding gases. After the heating has reached a maximum the bell slowly sinks until in its lowest position it just floats. A cock h is then opened and the bell removed. In an alternative method the cock h is open when the bell is introduced and closed after it has sunk, the oxygen then being extracted as before. In a modification the receptacle b is separated from the sealing liquid by a cooling jacket having a cylindrical partition forming an annular chamber in which are arranged helical guide vanes to control the circulation of a cooling liquid.

Filed: 1936-05-07
Abstract: 479,516. Fire - alarm systems. STELJES, W. S. May 7, 1936, No. 12876. [Class 40 (i)] In a fire-alarm system of the kind wherein signals are transmitted from street boxes over a closed line circuit under normal working conditions and over an earth return under fault conditions, an indicating device is provided in each street box and is adapted to be operated from the fire station. As shown, the street box apparatus B is connected to the fire station C over a normally closed loop circuit including relays j, j<1>, resistance h and short-circuiting contacts g, g<1> of a relay d. When the transmitting apparatus of the box B is operated contacts g, g<1> are opened, but relay d remains inoperative to the normal signal current. Upon receipt of the signal at the fire station, key i is operated to shortcircuit the resistance h and cause operation of relay d and indicator lamp f. In order to ensure correct operation when the system is working under emergency conditions, relays j, j<1> pull up to earth the line through resistances j<2> and thus prevent inadvertent operation of relay d due to the decrease of line resistance and the consequent increase of the line current. The Provisional Specification describes a system wherein the indicating lamp is directly included in the line circuit and is operated by switching into the circuit an additional battery in the fire station.

Title: Improvements in the production of phosphine
Inventor: LOWE EDWARD JAMES
IPC: C01B25/06
Filed: 1962-04-04
Abstract: Phosphine is made, with or without a finely-divided red phosphorus as by-product, by mixing phosphorus with a liquid water/phosphorus pentoxide system at a temperature above 250 DEG  C. and a pressure not substantially above atmospheric, in a graphite or silica reactor. For the best yield of phosphine, white phosphorus is heated in the acid medium until 50% conversion to red phosphorus has occurred.  The remaining white phosphorus is distilled away as rapidly as possible leaving a honeycomb trace of red phosphorus.  When the white phosphorus content reaches 4-0.1% by weight of the total phosphorus content, phosphine is evolved at a high rate and the red phosphorus is converted to a finely divided form.  White phosphorus to maintain the 4-0.1% proportion and steam may be added for continuous production of phosphine. For maximum yield of red phosphorus, the white phosphorus must be removed rapidly to minimize the time during which the white phosphorus content is 4 to 0.1%.  Examples are given.
