Title: Improvement in regulating valve for central heating plants
IPC: F24D19/10
Filed: 1935-12-31
Abstract: 457,993. Heating buildings. AKTIEBOLGATET CENTRALVENTILEN, 5, Drottninggatan, Stockholm.-(Assignees of Thiman, G.; 6, Borgmõstaregatan, Stockholm) Dec. 31, 1935, No. 36096. Convention date, Jan. 2. [Class 64 (ii)] [See also Group XXIX] A regulating valve for hot - water heating installations has a valve casing 1 with two inlets 14,13 and two outlets 11, 12, the outlet 12 being in communication with the two inlets through openings 16, 17 controlled by a valve 15. The inlet 14 and the outlet 11 are in free communication. The inlets 14, 13 are connected respectively to the hot water pipe 10 from the boiler 2 and to a byepass pipe 7 branching from the return pipe 8 from the radiator or radiators 4. The outlets 11, 12 lead to a hot water tank 3 and to the riser pipe 6 to the radiators respectively. The spindle of the valve 15 is screwthreaded so that it can be adjusted to close the opening 16 and so shut off the radiators entirely or move to an intermediate position to control the mixture of hot water from the boiler and cooled return water passing to the radiators. When the opening 16 is closed, the pressure in the tank 3 is relieved by a ball valve 22 in a byepass passage 20, 21. The inlet 13 is formed on a separate part of the casing which can be mounted in four different angular positions on the main casing by screws or the like.

Filed: 1972-08-02
Abstract: 1399636 Gas detecting apparatus YAZAKI SOGYO KK 2 Aug 1972 36157/72 Heading G1N [Also in Division G3] In a gas detecting device having at least one semi-conductor gas detecting element ELEM, an A.C. voltage, sufficiently low so as not to produce self-heating of the element, is applied to electrodes of the element, the change in resistance of the element due to the gas being converted into a voltage which is applied to a differential amplifier. As shown, the element is arranged in a bridge with resistances R 1 , R 2  and R 3 , the heater of the element, which also forms one electrode being applied with a voltage tapped from a transformer T, and the A.C. voltage applied to the electrodes also being tapped from the transformer. The bridge output is connected to a differential amplifier having a pair of transistors Tr 1 , Tr 2 . Upon detection of gas, a relay is energized to operate a switch which causes an alarm to be energized, and a gas supply to be switched off. As shown in Fig.4, a number of elements may be connected in parallel. When the device is to be used at a location where an A.C. supply is not available, means may be provided to convert a D.C. voltage into an A.C. voltage, Fig.6 (not shown).

Title: Improvements in and relating to the automatic regulation of the exchange power between interconnected electric power stations
IPC: H02J3/46

Abstract: 370,408. Centrifugal governors. AKT.- GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Dec. 23, 1930, No. 38671. Convention date, May 10. [Class 57.] Regulating during running.-In controlling the interchange of power between two or more electric generators or generating stations supplying a network automatically from a point or an interconnecting conductor the governors in the stations interconnected are simultaneously regulated in opposite senses, so that the frequency of the system as a whole is unaffected. The regulation is such as to take account of the difference in governor characteristics, of the size of the stations or generating units and of the number of machines in operation. The governor adjusting motors M in two stations St1, St2 may be regulated by means of a power measuring device F on the interconnector which transmits a representative current to a comparing member V where it is balanced against a current, adjusted for example by hand, according to the interchange power required, and relays R1, R2 are energized in accordance with the state of unbalance to transmit controlling currents to the motors M. Fig. 2 shows an arrangement for controlling several machines in a power station irrespective of the number or size of such in operation. The armature circuits of the governor motors 1, 2, 3 are in series connection with the control source and a resistance 6, the fields being excited from the same source. When a machine is out of commission its governor motor is short-circuited as by a switch 1b to which are linked switches which open respectively the field circuit and the circuits of resistances normally in parallel with each of the remaining motor armatures. Thus the amount of regulation of load achieved by a given control current is made independent of the number or size of the machines in operation, since the response of the individual governor motors is adjusted in accordance with the output of that machine and with its governor characteristic by selection of the values of the resistances which, with the resistance 6, constitute a potentiometer determining the voltage applied to the armature of each governor motor and hence its speed.
