Title: Improvements in dyeing cellulose ethers and esters
IPC: C09B1/32
Filed: 1936-12-30
Abstract: Materials made of or containing cellulose esters or ethers are dyed by applying thereto from an aqueous bath an anthraquinone-b -carboxylic acid substituted in one a -position by an arylamino group and in at least one other a -position by an amino or substituted amino group, the carboxyl group being in adjacent position to an amino group in a -position.  The dyestuff may be used in the form of an aqueous suspension of the free acid or of an aqueous solution of its salts, such as the sodium, ammonium or triethanolamine salt. Specified dyestuffs are the 1-amino-4-anilino- and the 1-amino-4p-toluidino-derivatives of anthraquinone-2-carboxylic acid. The pH value of the dye bath may be adjusted by the addition of ammonium salts or of organic or inorganic acids and the addition of a neutral salt, such as sodium sulphate, is advantageous.  In an example acetate artificial silk is treated for 1 hour in an aqueous solution at 70 DEG  C. containing the ammonium salt of 1-amino-4-anilinoanthraquinone-2-carboxylic acid and sodium sulphate to obtain a fast greenish blue dyeing.

Title: Improvements in or relating to a signalling system for telephone coin box apparatus
IPC: H04M17/02
Filed: 1955-12-19
Abstract: 784,032. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 19, 1955 [Dec. 23, 1954], No. 36374/55. Class 40 (4). In a telephone system a coin is deposited in a. coin box when a called subscriber replies, the connection being broken in the calling subscriber's line circuit and not restored until two relays are operated in correct sequence in response to the energization of a deposit magnet which disconnects the calling telephone set and releases a coin from a holding pawl to operate a coin shoot contact. The two relays ensure that fraudulent return of earth over a speech wire to the exchange from the subscriber's telephone set, to simulate operation of the coin shoot contact, upsets the sequence of operation and prevents restoration of the connection. In setting up a connection from a subscriber's set A, Fig. 2 or 3, over a line ab to an exchange, Fig. 1, relay LR responds to start line-finder S and operates holding relay R4 by means not illustrated. Relay BR and feed relay R3 respond when the line is found. The caller dials for a connection and if a reply is received relay R1 responds, followed by relay R2, which is slow to make and release, and relay KR1. R2 holds up in dependence on R4 while KR1 holds up in dependence on R2, BR, and either of KR2 and KR3. In responding KR1 breaks the connection between subscribers and connects a battery BAT over the windings of KR2 and KR3 to the a speech wire which is connected over a rectifier L, Fig. 2, or a gas discharge tube G, Fig. 3, to a deposit magnet M. The current in the circuit is sufficient to operate magnet M which withdraws a pawl P1 to release a coin held in suspense in a coin shoot. The coin falls to operate a contact k, where it may be held by a second pawl P2, Fig. 3, but before it does so relay KR3, which is slow to operate, pulls back. Relay KR2 does not operate in the circuit until contact k is closed by the coin to short-circuit the magnet M and increase current in the circuit; Providing KR3 pulls up before KR2, KR1 is released to restore the connection before hold relay R4 falls back. The connection is held for as long as is desired and when released relay R2 is last to fall back and in consequence operates the subscriber's meter SM. If there is no coin deposited after a call has been set up, KR2 does not respond and holding relay R4 falls back to release the connection. Fraud is prevented in that earth may be put on the a wire within the telephone set A when KR1 is energized but no coin is deposited. If this is attempted relay KR2 will operate before KR3 to short-circuit the winding of KR3 so that the connection remains broken and releases with R4; or, if such an earth is applied after deposit magnet M is energized, it will have no effect as a contact m of the magnet disconnects the telephone set.

In a fluid filter device comprising filter elements 29, 60 mounted coaxially about rod 22, fluid enters by inlet 14, fills annular groove 16, flows through perforations 14A in inner housing 17 into the annular space between housing 17 and element 29, through elements 29 and 60, through central opening 23A in retaining member 23, and out by 15. [Back-up cylinder 30 has end flanges 30A, 30B seated in retainer cap 31 and member 23 respectively.] Spring members 32 clamp elements 29 between cup 31 and member 23. Valve member 38 is axially slidably carried on rod 22 and has outer surface 42 which slides against surface 43 of retainer cup 31. Valve 38 is provided with grooves 46 and perforations 47 (Fig. 5 not shown); flange 44 of the valve is urged against the inner surface of cap member 12 by spring 40. As element 29 becomes clogged, the pressure differential across valve 38 produces axial movement of the valve member against spring 40, and causes actuator member 52 to produce a coresponding movement of pointer element 49 on an indicator plate (Fig. 2 not shown). As clogging increases, grooves 46 come into communication with the inner surface of element 29 thus providing a by-fall route through perforations 47 and grooves 46 from the inlet to the outlet side of element 29. The inner housing and filter element assembly may be removed with cap 12.
