Title: Lightning arrester cooling apparatus
IPC: H02B3/00
Filed: 1969-06-05
Abstract: 1276365 Lightning arresters GENERAL ELECTRIC CO 5 June 1969 [11 July 1968] 28394/69 Heading H2H A lightning arrester includes an arrangement whereby heat generated within the arrester is rapidly conducted to the exterior of the arrester housing. In the embodiment shown in Fig. 2, the arrester includes four non-linear resistors 13-16 connected across a spark-gap stack. Leakage current through these resistors causes them to generate heat. The resistors are connected in series through coil springs 20-22 which also urge them outwards, improving their contact with the housing 2. A layer 34 of a material such as epoxy may also be used to improve further the thermal contact between the resistors 13- 16 and the housing, enabling heat to be conducted more rapidly to the exterior of the arrester. In a modification, the arrester may be filled with a gas such as helium which conducts heat better than does air. In further embodiments, Figs. 3-5 (not shown), an arrester of the type shown in Fig. 2 further includes a system of pipes through which a coolant fluid moves by either natural or forced convection. A controlling thermostat and external heat exchanger may also be provided. The cooling systems for a number of arresters may be combined in a single fluid circulation arrangement (Fig. 5).

Title: Method and apparatus for the recovery of energy from the spent gases of a catalytic cracking unit
IPC: C10G11/18
Filed: 1963-07-22
Abstract: <PICT:0986510/C4-C5/1> Energy is recovered from spent hot regenerator gases from a catalytic cracking unit from which gases catalyst has been removed by burning at their superatmospheric pressure in a high pressure steam boiler together with extra fuel and air after which the combustion gases from the boiler at a controlled temperature are expanded in at least one gas turbine/compressor unit, the compressor(s) of which supplies combustion air for the regenerator and the boiler. The temperature of gases entering the turbine is controlled to prevent damage to the blades which would occur if the temperature were too high and maintain the output of the turbines which would drop if the temperature were too low. Spent gases from regnerator 1 are passed through a cyclone 5 or other separator and then into a combustion section 8 of steam boiler 7 together with air from line 12 and a fuel/air mixture in burner 13.  Steam is produced in section 9 at about 50 atmospheres and can be expanded to the normal 18 atmospheres in gas turbine/compressor units supplying gases to the cracking unit. The temperature of the gases is adjusted before leaving the boiler in section 10 by adding heat by burning fuel in burner 18 or cooling by adding water from spray 19 automatically controlled by controllers 23 responsive to the temperature in line 20. Turbine/compressor 31/32 provides air for the regenerator 1; the amount is automatically controlled by adjustment of excess flowing through valve 43 which is passed to line 46 together with the output of turbine/compressor 29/30 to supply air for the boiler. Heat is recovered in heat exchanger 37 which preheats the water feed to the boiler.  Pressure in the regenerator is controlled by control of valve 50 or valve 48.

Patent GB-639681-A (GB)
Title: Improvements in or relating to the production of guandine sulphates
Filed: 1947-11-03
Abstract: A guanidine sulphate is produced by reacting carbon dioxide, ammonia and sulphur trioxide in the gaseous phase at elevated temperature. Instead of using the gaseous reactants, one or more of them may be replaced by materials which at the temperature of the reaction decompose to form such gaseous reactants.  Thus ammonium carbamate will provide ammonia and carbon dioxide, sodium chlorsulphonate will provide sulphur trioxide and sulphamic acid or ammonium sulphamate will yield sulphur trioxide and ammonia.  The reaction temperature is preferably 250-400 DEG  C. and the total pressure of the reactants is preferably at least 300 lbs./sq. inch.  It is also preferred to use the reactants in the ratio of 1 mol. of carbon dioxide, 1-2 mols. of sulphur trioxide and 2-6 mols. of ammonia.  Either diguanidine sulphate or monoguanidine sulphate may predominate according to the conditions, but adjustment of the pH of an aqueous solution of the guanidine sulphate will yield the monoguanidine sulphate which obtains at a pH of 2 or diguanidine sulphate which may be isolated from a solution having a pH of 7.  The process may be carried out continuously, in which case the gases are pumped under pressure through a reactor at the desired temperature and then through a cooling zone to solidify the product.  The unreacted gases are then passed through solids collecting apparatus and then recycled with appropriate additional amounts of reactants.  The guanidine sulphate may be isolated by cooling or evaporating to cause crystallization or by precipitation by adding ethanol or other water-miscible organic liquid.  The guanidine may, however, be isolated as a less soluble salt such as a picrate, carbonate or phosphate, by adding the corresponding acid to the aqueous solution of the sulphate and then inducing crystallization.  Free guanidine may be obtained by dissolving the dry sulphates in ethanol and adding an excess of potassium hydroxide to precipitate the sulphate ion as potassium sulphate.  In examples: (1) and (2) a mixture of carbon dioxide, sulphur trioxide and ammonia is reacted in an autoclave heated to 350 DEG  C. and 325 DEG  C. respectively, the solid reaction product is washed out with water yielding mainly diguanidine sulphate; (3) ammonium carbamate and sulphamic acid are heated in an autoclave, the solid product washed out with water and the guanidine sulphate solution thus obtained is treated with an excess of picric acid to precipitate guanidine picrate; (4) ammonium carbamate and ammonium sulphamate are heated in an autoclave, the solid product dissolved in ethanol and treated with excess alcoholic caustic potash to precipitate potassium sulphate and yield a solution of free guanidine; (5) carbon dioxide, ammonia and sodium chlorosulphonate are heated in an autoclave and the solid product washed out with water to form a solution of guanidine sulphate. It is stated that if the reaction temperature is substantially above 400 DEG  C., decomposition occurs with formation of melamine.

Abstract: 1,093,196. Lathes. ZAKLADY PRZEMYSLU METALOWEGO H. CEGIELSKIPOZNAN. June 30, 1966 [July 2, 1965], No. 29360/66. Heading B3T. A device for stopping the spindle 1 of an automatic lathe in a predetermined angular position comprises an electromagnetic brake 2 and an index plate 7 attached to the spindle. A locking plunger 9, operated electromagnetically, is adapted to engage notches in the index plate in response to the action of cam discs 13, 16 mounted on a control shaft in the lathe which operate micro-switches 15 and 18 respectively. The closing of micro-switch 15 by the cam 14 energizes the brake electromagnet 2 to brake the spindle. Simultaneously, the time delay relay 19 is energized to actuate the brake motor 4 and magnet of the locking plunger 9 which subsequently contacts the surface of the index plate while the motor 4 slowly turns the spindle 1 until the plunger 9 engages the required notch in the index plate. This movement actuates the micro-switch by means of contact 11 which shuts off the electrical supply to the motor 4 any subsequent movement of the motor 4 being absorbed by the over-riding clutch 6. The next indexing position of the spindle is controlled by means of the disc 16 which actuates switch 18 to re-energize the circuit so as to rotate the spindle by the motor 4.
