Convention date, Feb. 17, 1932. [Class 40 (iv).] In a multiplying scheme primarily for line switches and call finders, the subscribers' lines are divided into groups A, B, C .... , while the trunks to which they are to be connected are divided into groups a, b, c, ...... , and each group of trunks is arranged to be first choice to the correspondingly lettered group of lines and second choice to another group of lines, so that each switch has access to two partial multiples, the combination being different for each group of switches. Fig. 3 shows an arrangement in which the groups of trunks a, b, c ... terminate in call-finders, denoted by arrow-heads, each having access to two adjacent groups of subscribers' lines. Calls in group B for example are extended normally by the finders of group b, but when all these are in use, the finders of group c are brought into service. Similarly when all the finders of group c are in use, further calls in group C may be dealt with by the finders of group d. Fig. 3<a> shows the corresponding arrangement in which the groups of lines A, B, C, .... terminate in line switches, denoted by arrow-heads, each having access to two adjacent groups of trunks. When the groups of subscribers' lines are sub-divided into sub-groups as shown in these arrangements, the modifications shown in Figs. 4, 4<a> may be adopted whereby the excess calls in different sub-groups of a group are extended over different groups of trunks. When all the trunks of group b are in use for example, further calls in the sub-groups B1-4 of group B are extended respectively over the trunks of groups c, d, e, f. When the arrangement of Fig. 4 is adopted for numerical final selectors, if the final selectors normally serving the wanted group are all in use, it is necessary for the penultimate selector to receive the tens digit in order to select a final selector serving the appropriate sub-group, the tens digit then being repeated thereto.

Title: Determination of iron in boiler water
IPC: G01N21/78
Filed: 1960-02-15
Abstract: 894,459. Determining iron in water colorimetrically. BABCOCK & WILCOX CO. Feb. 15, 1960 [April 1, 1959], No. 5261/60. Class 1(1) The iron content of boiler feed water is determined by continuously removing a sample, continuously maintaining its pH at a predetermined value, oxidizing the iron in the sample, filtering a selected volume of the sample and comparing the colour of the retained iron oxide with a colour standard. The pH is preferably from 7À2-7À6 and the preferred oxidizing agent is hydrogen peroxide; other contaminants (e.g. Cu or SiO 2 ) may be removed before oxidation by filtration. Fig. 3 illustrates a determination in which a sample is withdrawn from a steam generating unit and passes through a cooler, flow control valve and capillary tube before the addition of a solution (e.g. of HCl or NaOH) to control the pH, and the oxidizing agent; a pH meter and a millivoltmeter are provided whereby the quantities of these reagents may be suitably regulated, the quantity of oxidizing agent being regulated in dependence on the conductivity and thus the quantity of Fe salt. The mixture is thereafter passed into a filter assembly in which a continuously or intermittently moving strip of filter paper is employed. After deposition of the iron oxide, the strip is dried and tested by reflected light transmitted to a photo-cell for comparison of the colour of the precipitate with respect to a colour standard. The method is stated to indicate as little as 5 parts per billion of iron in feed water.

An opening spring 19 is placed between an abutment 22 for the member 12 and the movable contact 7, which is pivoted at 16 to the member 13. A roller 26 on the member 13 is engageable in the closed position by a holding latch 24, which is pivoted at 25 and carries an extension 29 which supports a tripping member 28, also pivoted at 26. The member 28 co-operates with the armature 11 of a series combined trip and blow-out magnet 8, and is arranged on overload to release both latches 24, 14 by means of, respectively, the extension 29 and a roller 30. Fig. 3 diagrammatically shows the closed position of the parts, in which the handle 12 is held against abutment 23. When the latches 24, 14 are deflected, the parts 12, 13 are uncoupled and the part 13 rotates clockwise, the contact 7 .wiping over the contact 6 until arrested by the part 13. Rotation of the latter causes the handle 12 to move clockwise by means of spring 21 and reset the latch 14, ready for reclosure, the latter being effected by counterclockwise rotation of handle 12 until the latch 24 re-engages the roller 26. If the contacts reclose on to an overload,. the parts are uncoupled at 14, 18, before the latch 24 is engaged, so that it is impossible to hold the breaker closed. The handle can also be rotated backwards to open the breaker by first disengaging 18 from 14 and then deflecting latch 24 to free the contacts.
