Filed: 1963-06-07
Abstract: Poly - (N - methylene - N1 - mercaptomethyl-1 - methyl - 4 - keto - hexahydro - 1,3,5 - triazine) is prepared by reacting hydrogen sulphide with 3,5 - dimethylol - 1 - methyl - 4-keto - hexahydro - 1,3,5 - triazine under acidic conditions.ALSO:Thioethers are prepared by reacting, under acidic conditions, an organic compound containing at least one methylol radical attached to a carbon, nitrogen or sulphur atom and capable of being prepared by reaction of formaldehyde with the corresponding compound not containing the methylol group or groups, with a sulphide of the formula RSH, where R is a hydrogen atom or a C1- 4 alkyl group, optionally having inorganic negative substituents, or an aryl, aralkyl or heterocyclic radical, but wherein R cannot be a hydrogen atom when the methylol radical is attached to a carbon atom.  Methylol compounds specified are N-methylol propionamide, N - methylol benzamide, N - allyl - N1 - methylol urea, N,N1-dimethylol urea, N,S-dimethylol urea, N,S-dimethylol isothiourea, N,N1-dimethylol ethylene urea, N,S-dimethylol ethylene isothiourea, hexamethylol melamine, 1 - methyl - 4 - keto - 3,5 - dimethylol - hexahydro - 1,3,5 - triazine, monomethylol acetone, monomethylol methyl ethyl ketone, dimethylol methyl ethyl ketone, 2,6-dimethylol-4-methyl phenol, dimethylol acetone, N-methylol thiobenzamide and N-monomethylol urea.  Specified sulphides of the formula RSH are hydrogen sulphide, p-nitrothiophenol, ethyl mercaptan, thiophenol, p-chlorothiophenol, methyl mercaptan, butyl mercaptan, 2-mercaptobenzthiazole and b -chloroethyl mercaptan.  The reaction may be carried out at 0 DEG  to 100 DEG  C. in an inert solvent and preferably at a pH below 5.  The molar ratio of methylol compound to sulphide may vary from 2 : 1 to 1 : 10.

Title: Improvements in or relating to method of and apparatus for coating paper and the like
Filed: 1936-08-19
Abstract: <PICT:0465556/IV/1> <PICT:0465556/IV/2> <PICT:0465556/IV/3> Apparatus for coating a travelling web of paper or the like with liquid, for example colour, comprises a rotating spray roll 15 mounted adjacent to, but not in contact with the web and fed by projecting liquid against its surface at a velocity less than the surface speed of the spray roll but in the same direction as its rotating surface, for example by spray from a transfer roll 10 rotating at a lower speed than and in the opposite direction to the spray roll.  A take-up roll 5 rotating in the same direction as but at a lower speed than the transfer roll 10 dips into a reservoir 2 and feeds the transfer roll with spray.  The take-up roll 5, Fig. 4, is provided with circumferential grooves 9 and doctors 7.  Similar grooves 12 are provided on the transfer roll 10 so that the flanges and grooves intermesh without actual contact.  The spray roll 15 has spiral grooves 18 and is provided with guards 19 to confine the spray.  A web 20 is drawn from a supply roll 40 around guide rolls 41, 42, beneath a suction box 21 and around guide rolls 43, 44 to a drier (not shown).  The bottom portion of the suction box 21 is formed by members 22, Fig. 3, extended inwardly from the sides to leave an opening 23.  A plurality of rolls 24 are positioned below members 22 and are rotated at web speed by a pulley 26.  A pair of rods 27, Fig. 1, slidably support adjustable deckles 28 the upper edges of which slide on the under side of the members 22 and of which the lower portions provided with projections 29, Fig. 1, extend downwardly between the rolls 24 thus sealing the space at the ends of the rolls 24.  Suction is applied to the suction box 21 through a conduit 34. In modifications the spray roll 15 may have a plurality of oppositely directed spiral grooves and an additional spray roll may be mounted behind the main spray roll to catch excess spray and return it to the web.  Two opposed coating units may be used to coat simultaneously both sides of the web.  Paper webs may be coated immediately after delivery from the paper making machine.  The apparatus may also be used for coating previously sized webs with fine powders such as gold, aluminium, or mica.

Title: Improvements in or relating to washing processes
IPC: D06L1/04
Filed: 1937-08-24
Abstract: 501,422. Washing textiles. POLLARD, C. T. Aug. 24,1937, No. 23227. [Class 15 (ii)] In a washing process in which the materials washed are first treated with a fatty acid component and then with an alkali component, the fatty acid component comprises an aqueous emulsion of a fatty acid (preferably oleio acid) together with methylcyclohexanol. Xylene, naphtha, or white spirit may also be present in the emulsion, and it is also advantageous to add thereto cyclohexylamine or monoethanolamine oleate. A solution of sodium metasilicate is preferably employed as alkali component. In an example, a fabric is first treated for 5 minutes in a rotary washing machine with an emulsion of fatty acids from olein, methylcyclohexanol (made by hydrogenating cresylic acid), naphtha and monoethanolamine oleate, sodium metasilicate solution is then added at a temperature of 160‹ F and the treatment is continued for 10 minutes. The fabric is then washed with dilute sodium metasilicate solution, boiled with a solution of sodium metasilicate and salt and rinsed. Specification 333,177, [Class 15 (i)], is referred to.

Title: Improvements in or relating to radio amplifying circuits
IPC: H01F1/20
Filed: 1930-08-01
Abstract: 366,475. Wireless receiving systems. JOHNSON LABORATORIES, Inc., 609, West Lake Street, Chicago, U.S.A.-(Assignees of Polydoroff, W. J. ; 609, West Lake Street, Chicago, U.S.A.) Aug. 1, 1930, No. 23255. Convention date, Aug. 26, 1929. [Class 40 (v).] A wireless receiver giving constant amplification over the whole tuning range is characterized by the use of tuning-inductances made with a core of very finely-powdered iron, produced for instance by reducing iron sulphate by the action of hydrogen. The iron particles should pass through a screen of 250-300 mesh to the inch. As shown in Fig. 4, primary and secondary coils 1, 2 are wound on an insulated tube 3, and powdered iron is packed inside the tube, and ends being sealed. Fig. 5 shows a binocular coil, 7, 8, the iron powder being separated into layers by thin paper discs 9. The iron powder may be mixed with wax, paraffin, mineral oils, rubber, gum, or varnish, and pressed or moulded into shape. In such coils, mutual inductance is greatly increased, affording a very tight coupling. The core may be movable relative to the windings. As shown in Fig. 8, the movable cores 19 are ganged together and to the tuning- control of a multivalve amplifier. In Fig. 16, the core 38 is moved relatively to the coil 39 through a lever 36 and a slotted cam 34 mounted on the rotary shaft 34 of a variable condenser. The arrangement is such that the core is fully inside the coil 39 when the condenser setting is zero, and vice versa. The core movement is accelerated as the capacity is increased, so as to ensure equally-wide frequency channels over the entire tuning range.

Abstract: 1,170,211. Measuring time intervals. AMERICAN MACHINE & FOUNDRY CO. 20 May, 1968 [31 May, 1967], No. 23881/68. Heading G4H. [Also in Division G1] Appatatus for measuring the time which a predetermined length of cigarette takes to burn includes a first photo-sensitive member e.g. a photo-sensitive transistor FU5 (Fig. 8) for sensing the burning of the cigarette at a specific fixed point, a second photo-sensitive member, preferably photo-sensitive transistor FU6, spaced a predetermined distance from the first member and a counter S for measuring the time between the sensing of the burnt cigarette by the first and second members. In the preferred embodiment in which the photo-transistors are positioned behind slots in a screen, a pulse generator B is enabled when a pushbutton G is closed so that, when a relay R is energized by the photo-transistor FU5 to close an associated contact R1, pulses from pulse generator B are accumulated in the counter S until the relay is de-energized by phototransistor FU6. Preferably the pulse generator B is shared between a plurality of cigarette testers. When relay R is de-energized contact R2 opens and contact R3 closes so that a condenser C discharges through the winding of a solenoid E causing it to retract a dog (11, Fig. 2, not shown) to release a movable jaw (8) so that the cigarette is dropped.
