Abstract: 1,263,170. Arc suppression. MAGRINIFABRICHE RIUNITE, MAGRINI SCARPA E MAGNANO M.S.M. S.p.A. 4 Aug., 1969 [9 Aug., 1968], No. 38915/69. Heading H1N. In an electric circuit-breaker comprising a number of main breaker chambers I 1 -I 4 , Fig. 2, at least one chamber I 1  (as shown) has a parallel connected making resistance R with a switch C closed prior to the simultaneous closing of the main chambers I 1 -I 4 . In a particular example the switch C comprises a movable plunger contact 11 engageable with a fixed contact 9 associated with a pile of resistance blocks 5. On actuation of the main shaft 26 for the chambers I 1 -I 4  (not shown) the contact 11 is initially closed by a cam 19 engaging a roller 23 and lifting it to the hatched position (shown). On further movement of the shaft 26 the main contacts close while the roller 23 is held by face f of the cam 19. After full closure of the main contacts the roller 23 is released to open the contacts 11, 9. During re-opening of the main chambers roller 23 moves in slot 22 against the action of spring 24 to permit the cam 19 to return clockwise to the off position.

Patent GB-342479-A (GB)
Title: Improvements in or relating to teleprinting systems
IPC: H04L12/06
Filed: 1929-12-27
Abstract: 342,479. Type-printing telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 27, 1929, No. 39618. Convention date, Dec. 28, 1928. [Class 40 (iii).] A teleprinter installation is provided with an automatic return signalling device which advises back a signal to the calling subscriber on the completion of a connection, and which is suited, in its mode of action, to the teleprinter installation so that the return signal may be received on a teleprinter receiver. In the example the return signal is sent by a rotary selector d1 .. d6. On the arrival of a calling impulse through the line L, the receiving relay E is energized and operates its contact e, thus energizing the relay X which operates and, by means of its contact x<1> energizes the relay Y, the contacts y1 and y2 of which operate to energize the driving motor M. At the same time the operation of the contact y3 energizes the relay J which operates and closes a holding circuit over the contact i2. The operation of the contact i1 energizes the relays V, D, the relay V being a retarded relay and operating its contacts v1, v2 to disconnect the transmitting apparatus T. The distributing relay D steps the arms d1 .. d6 one contact, thus placing + - + - + on the segments 1 .. 5 of the distributor, the brush B of which then rotates and sends a five-code signal to the calling station. At the same time the contact a, operated by the controlling shaft through the cam N, opens thus de-energizing relay J and hence the relay D. On the termination of a revolution of the cam N the contact a is again closed, thus switching in the relay J so that relay D operates again and the selector makes a further, step. This operation is repeated until the arm d1 has run to its last contact where it remains since the contact x3 is open. The rotary movement of the brush B is released once every revolution of the control shaft by a control magnet st which is energized on the operation of the relay J through the contact i3 by the charging current of a condenser C. When the selector arrives at its last contact the retarded relay V drops and switches the transmitting apparatus T into the line so that normal traffic may take place. On the termination of traffic the contact e opens permanently and the retarded relays X, Y fall off, thus closing the contact x3 and once more operating the magnet D through the operation of the relay J, thus switching the selector arms to the neutral contact and leaving the station clear. With outgoing traffic the switches An1, An2 are closed and opened respectively, thus operating the relay Y and preventing the operation of the relay J so that the return signalling apparatus does not come into operation. Any form of current impulse-giver suitable for the purpose may be used for giving the return signal, as for example a perforated strip sender which may take the form of an endless band.

The sections dispensing warm and lukewarm water each have a ceramic closure member 69 (Fig. 3) co-operating with a like seat V having hot and cold ports 17, 19 the flow to which is controlled by proportioning plug T. The closure member is carried by a slider M operated through sealing boot E by follower S, wedge P and a lever R supported in block L. The sections dispensing hot and cold unmixed water are similar except that plug T is omitted and the closure member (minus slider M) controls a single port only. The seats are located by a common gasket G, and the closure members and sliders are guided by common cage K. In each section, flow takes place around the closure members and sliders to common outlet dp. The mixing sections have stabilizing trickle grooves 73 through which initial flow occurs. In the modification of Fig. 7, each mixing section has opposed hot and cold inlet ports 17, 19 controlled by respective closure members M. A plug T controls-flow to port 17 to establish the desired temperature. In the hot and cold sections, a dummy slider is used in place of one closure member.

Chemically-dosed water enters under pressure, at 1, a coagulation zone A. Thereafter it passes upwardly, at 3, into a zone B where a fullyfluidised sludge blanket forms; next it passes upwards into a clarified water zone D. From there it is led by delivery pipes 11 to a trough 12 in an expansion zone E, whence it passes downwards through a granular filter bed zone F to an underdrainage zone G. From the top of the sludgeblanket zone B, water containing an excess of flocculated particles is withdrawn by sludge drawoff apertures 5 and constrained by a baffle 6 to flow into a sedimentation zone C. From here, sludge is drawn off at 14, while water from the top of the zone flows along a collecting pipe 7 and through a regulating valve into the expansion zone E.
