Title: Improvements in or relating to the manufacture of the nitriles of organic carboxylicacids
Filed: 1939-06-07
Abstract: 530,269. Nitriles. DREYFUS, H. June 7, 1939, Nos. 16694 and 19707. [Class 2 (iii)] Nitriles of carboxylic acids are made by dehydrating amides or ammonium salts of the acids with the anhydride of an aliphatic monocarboxylic acid such as acetic anhydride. The production of dinitriles of aliphatic acids such as suberic and sebacic acids, aromatic acids and aliphatic-aromatic acids such as benzylmalonic acid, dicyanogen, and the nitriles of higher fatty acids such as lauric, palmitic, and stearic acids is mentioned, the particular description relating to a diponitrile. The reaction temperature may be such that the aliphatic acid produced from the anhydride distils off, and a diluent which forms anazeotropic mixture with such acid may be employed, or the diluent may be of relatively high boiling-point. Preferably the amide is added a little at a time to excess of the anhydride. When an ammonium salt is the initial material a greater excess of anhydride is used, and if desired the reaction can be carried out in two stages, the ammonium salt being added a little at a time in the first stage, and then more anhydride being added to effect the second stage. In an example, adipamide is added a little at a time to a body of boiling acetic anhydride under reflux.

Title: Thermoelectric cooling system
IPC: G05D23/275
Filed: 1965-04-21
Abstract: 1,097,662. Thermocouples. BORG-WARNER CORPORATION. April 21, 1965 [May 6, 1964], No. 16811/65. Heading H1K. [Also in Division G3] When the conductive heat transfer through a Peltier cooling system is sufficient to accommodate the required cooling load the direct current power supply to the cooler is cut off and a resistor connected across it to form a closed circuit with the elements of the cooler and resistor in series. In a typical air-conditioning system, illustrated in Fig. 2, the switch 28 and variable supply transformer 41 are controlled by unit 35 which responds to changes in the internal temperature measured at 44 and in the temperature outside measured at 34. As the outside temperature falls from a high value the voltage applied to the cooler is progressively reduced by the variable transformer 40 to zero when the Seebeck voltage is still producing some current in the cooler. The switch is then automatically operated to connect resistor 36 across the cooler to reduce this current. If this is still insufficient the cooler is automatically connected in reverse to the power supply to further reduce or reverse the current therein.
