Title: Device for heating liquids electrically
IPC: F24H1/20
Filed: 1952-10-10
Abstract: 719,433. Electric liquid heaters. BANGERT, H. Oct. 10, 1952, [Oct. 11, 1951.] No. 25465/52. Class 39 (3). An electric liquid heater having a liquid container 21 and liquid inlet and outlet ducts 24, 25, and in the container 21 a heating resistance controlled by a heatresponsive switch in circuit therewith in which the switch breaks the circuit at a temperature higher than that at which it closes the circuit, is characterized in that the ratio of electrical energy absorbed by the resistance in K.W. to the volume of liquid in litres in the container 21 when full, is greater than 1 and preferably between 4 and 8. The apparatus comprises the container 21 having a water inlet 24 and an outlet 25, three electric heating coils 30 32, 33 connected to the respective phases of a 3-phase supply, and two temperature-responsive mercury switches 31, 35 connected in series in the heater circuit. Valves 34, 23, control the inlet 24 and the outlet 25 respectively. The thermostatic element 29 of switch 31 depends in a tube 27 fixed to the inlet 24, and so is responsive to the inlet water temperature only, being adjusted to "cycle" between the temperatures of 40‹C. and 20‹C. The corresponding element 36 of switch 35 is responsive to the temperature of the water in the container 21 and "cycle" between 65‹C. and 62‹C. As long as the outlet valve 23 is kept closed the water in the container is kept at about 40‹C. by the switch 31, but on opening the valve 23 and fresh cold water (i.e. less than 40‹C.) entering the container, the switch 31 is maintained closed and the switch 35 acts to deliver hot water at about 65‹C. If desired, each phase of the supply may have a separate mercury switch. In a modification, Fig. 2 (not shown) the inlet valve is dispensed with, and one thermostat only, corresponding to 36 in Fig. 2, is used. The switch-off temperature is again 65‹C., the switch-on temperature being preferably 10 or 20‹C. lower.

Title: Improvements in apparatus for the automatic operation of vacuum pumps in large rectifier installations
IPC: H01J13/28
Filed: 1923-10-15
Abstract: 205,509. Akt.-Ges. Brown, Boveri, et Cie. Oct. 14, 1922, [Convention date]. Low-pressure metallic-vapour apparatus. - In apparatus for the automatic operation of vacuum pumps in rectifier installations, the controlling device for the pumps is provided with retarding- mechanism whereby the pumps are stopped after a predetermined time, for instance half-an-hour, after a good vacuum has been established, and if the vacuum is already good when the pumps are started, the same period elapses before they are stopped. The pumps may be started after each switching-in or out of one or more rectifiers. As shown the winding of a time-relay c is in series with a pressure gauge b, a switch l controlled by a clock k, and a switch o operated by the main switch h. The winding of a relay d is in series with the contacts of the time-relay c. When the vacuum is reduced or the switch l is opened momentarily by the clock k, the winding of the time-relay and, consequently, the winding of the relay d, are de-energized, and the relay d closes the circuit of an electromagnet e, which closes the switch g of a motor m driving a pump n. The switch h may be closed automatically a short time after the pump is put into operation. Pumping continues for the period, say half-anhour, for which the time-relay is set, and the relay winding d is then energized by the timerelay so as to open the circuit of the electromagnet e, and close the circuit of a winding which opens the switch g. If a short-circuit occurs the winding of the time-relay is deenergized momentarily by the switch o, and the pump put into operation. The windings of the relays and switches are connected with a transformer i.
