Title: Salts of arylguanidines with aryldiazosulfonates or with aryltetrazodisulphonates
IPC: G03C1/56
Filed: 1957-12-30
Abstract: The invention comprises aryl guanidine salts of diazosulphonates soluble in organic solvents, having the general formula <FORM:0830306/IV (b)/1> wherein Ar is an aromatic radical and R is hydrogen or an aromatic radical, at least two R's being an aromatic radical and at least one R being hydrogen.  The invention also comprises aryl guanidine salts of tetra-azo-disulphonates.  The salts are photo-sensitive and suitable for use in the manufacture of paper and metal lithographic plates.  The salts are prepared by reacting an aqueous solution of an alkali-metal aryldiazosulphonate or aryltetrazodisulphonate with an arylguanidine acetate.  In Example 1, a solution of 1,3-di-o-tolylguanidine in aqueous acetic acid is added, with stirring at 35-40 DEG  C., to a solution of sodium p-ethoxybenzenediazosulphonate in water containing a low concentration of acetic acid.  Yellow crystals having the probable structure <FORM:0830306/IV (b)/2> are precipitated.  In Example 2, an acetic acid solution of 1,3-di-o-tolylguanidine is added to an aqueous solution of sodium 3-chloro-4,6-dimethoxybenzenediazosulphonate.  A red oil is formed which is washed with water and allowed to stand.  After 4 days the oil changes to yellow crystals of a salt having a chlorine atom and two methoxy groups in the benzene ring of the diazosulphonate part of the molecule.  Example 5 describes the preparation of orange crystals having the structure <FORM:0830306/IV (b)/3> by treating an aqueous solution of sodium p-acetamidobenzenediazosulphonate with an aqueous solution of 1,3-di-o-tolylguanidine acetate.  In Example (6), 2,21-methylenebis-(4-nitrophenol) is treated with ethyl sulphate and alkali; and the resulting methylenebis-(4-nitrophenetole) is reduced to 3,31-methylenebis-(p-phenetidine).  The hydrochloride of this base is tetrazotized and converted to the corresponding methylenebis - (4 - ethoxybenzenediazosulphonate).  An aqueous solution of the latter is then reacted with an aqueous solution of 1,3-di-o-tolylguanidine acetate whereupon there separates a yellowish-brown mass having the structure <FORM:0830306/IV (b)/4> In Example 7, a solution of N-benzyl-N-ethyl-p - aminobenzenediasonium chloride zinc chloride double salt is treated with sodium sulphite to give the diazosulphonate; and the latter is then reacted with 1,3-di-o-tolyl-guanidine acetate. There is obtained a yellow crystalline product having the structure <FORM:0830306/IV (b)/5> Example 8 describes the preparation of 1,2,3-triphenylguanidine - p - ethoxybenzene - diazosulphonate.  A list of aryldiazosulphonates, which may be used for the salt formation, is given.  There is also a list of suitable arylguanidines, which includes 1-(p-lauroylaminophenyl)-3-phenylguanidine and 1-(p-dodecyl-sulphamoylphenyl)-3-phenylguanidine.

Abstract: 976,997. Depository machines. UNIVERSAL MATCH CORPORATION. Nov. 1, 1962, No. 41332/62. Heading A4T. [Also in Division B6] In a depository machine a depositor opens a door and places a bundle e.g. envelope 16, having its top flap tucked beneath its bottom flap and containing papers e.g. money bills or cheques, on a plate 26 to actuate a relay switch 30 therein. On closing the door a switch 29 is actuated whereby a solenoid actuated stamp 27 imprints data on the envelope and locks the door. A solenoid actuated roller 31 then grips the envelope on a roller 33 so that the envelope is moved to the right by motor 34 where the flap is opened by guides 36, 37 and cut off by cutter 42 as the envelope passes between rollers 39, 45 also driven by motor 34. The envelope passes on to platform 50 where it actuates two switches 51, 52 whereby motor 34 is stopped and solenoid 54 energized to pull down frame 56 so that rollers 57, 58 engage the papers at the envelope opening. Motor 61 via belts 62, 69 respectively drives the rollers and an endless belt 63 whereby the papers are fed out of the envelope on to the belt, an edge of bristles 53 permitting only one paper at a time to be removed from the envelope. Each paper on the belt 63 is photographed by an overhead camera actuated by a switch or in timed sequence after which the paper is fed to a shoot 67 leading to an in accessible bin 68. When all papers have been removed from the envelope the envelope itself is removed from shelf 50 on to belt 63 and actuates switches 51, 52 to eventually stop motor 61 and de-energize solenoid 54, actuate a solenoid which raises shoot 67 to the horizontal position, energize solenoid 83 to lower rollers 81, 82 which grip the envelope after leaving belt 63 and having been photographed, and starts motor 79 which via belt 80 turns the rollers and shifts the envelope on to a shoot 84 where the depositor retrieves it as a receipt. On shoot 84 the envelope trips a switch 85 which switches off motor 79 and solenoid 83, and de-energizes solenoid 27 so that the envelope receiving door is opened. A known type of steam jet may be used to unseal a stuck envelope flap in the receiving tray 26. A press button switch may be used to reopen the receiving door if it is shut without an envelope having been placed in tray 26 to actuate switch 30. Specification 910,988 is referred to.
