Filed: 1947-06-17
Abstract: 652,244. Coating webs. FIRESTONE TYRE & RUBBER CO., Ltd., and COLLINS, J. B. June 17, 1947, No. 15977. [Class 140] A calender for forming an insulating coating, e.g. of rubber, and applying it to a backing material as it passes over one bowl of the calender, comprises an electric circuit controlled by said film such that a discontinuity therein energizes a relay to stop the calender. In a three bowl calender the rubber, taken up by the top roll 1 is applied to the backing in the nip of the lower and bottom rolls 2, 3. An electrically conducting rod 8 parallel to the middle bowl 2 carries a number of tubes 7 each having attached a U-member 6, bearing spring contacts 5 urged against the bowl or coating thereon by a weight 9 attached to the other arm of the U. The contacts and the bowl are in series in an electric circuit, Fig. 3, supplied at 15 volts from the secondary of a transformer 16 receiving its energy at 230 volts. In series with the contacts 5 and bowl 2 is the primary of a transformer 17, the secondary of which energizes at 110 volts a relay 18 which operates a circuit 18a for stopping the calender motor. A signal lamp 19 is also included in the relay circuit. A press button 20 is provided to de-energize the system. Discontinuity of the rubber coating film allows contact between the contacts 5 and the bowl 2 to close the circuit, causing the calender to stop and the lamp 19 to light. To restart the calender, the press button 20 must be held closed until the bowl is again covered with rubber. In order to put the device out of action a lifter bar 11 is provided carried by levers 12 pivoted at 13 in brackets 10 carried by the machine frame and which levers also carry a bar 15 to facilitate raising and lowering of the bar 11. In a modification, the electric circuit comprises a condenser, one plate of which is constituted by the bowl of the calender and the other by an arcuate plate parallel to a part of said surface, the coating material acting as the condenser dielectric discontinuity of which alters the capacity of the condenser to influence the circuit to which it is connected and thus stop the calender. According to the Provisional Specification, the electric circuit may operate to control the calender in any desired manner.

Title: Treatment of cellulosic textile materials, paper, films and the like
IPC: D06M13/46
Filed: 1936-06-08
Abstract: Water-repellent properties are imparted to cellulosic materials by impregnating them with a quaternary ammonium salt of the general formula NR<1>R<11>--CH2--N(tert)--X (where R<1> and R<11> stand for radicals at least one of which consists of or contains an aliphatic hydrocarbon radical of 10 or more carbon atoms, N(tert) stands for the nitrogen atom of an aliphatic or heterocyclic tertiary amine, and X stands for the radical of a salt-forming acid) applied from aqueous medium, and if desired, after drying subsequently heating the impregnated material to a temperature such that the said salt decomposes. The group NR<1>R<11> may have the form Alph--CO--NR<11>-- or Alph--N(COOR<11>)-- in which Alph is a higher aliphatic radical, i.e. of 10 or more carbon atoms. Methods of making such compounds are described in Specifications 471,130 and 475,170.  When drying is effected after impregnation and before heating, this should be carried out in a rapid current of hot air, or alternatively the drying should be carried out at a temperature below 40 DEG  C. so as to avoid decomposition of the quaternary salt.  The optimum heating or baking temperature is 90--120 DEG  C.  In the examples given the following quaternary salts are used, stearamidomethyl pyridinium chloride, bromide or nitrate, stearomethylamidomethyl pyridinium chloride, stearamidomethyl pyridinium hydrogen sulphate, N-carbomethoxyheptadecylaminomethyl pyridinium chloride (obtained from methyl heptadecylcarbamate, formaldehyde, hydrogen chloride, and pyridine), palmitoamidomethyl pyridinium chloride, stearamidomethyl pyridinium sulphite (prepared from stearamide, pyridine, paraformaldehyde and sulphur dioxide), stearamidomethyl pyridinium - m - dinitrobenzene - sulphonate, N - carbomethoxyundecylaminomethyl pyridinium chloride, oleylamidomethyl pyridinium chloride, lauramidomethyl pyridinium chloride, and lauramidomethyl pyridinium sulphate.  In place of the above fatty acids, the acids of palm oil, cotton seed oil, tallow or hydrogenated fats may be used.  Other amines are those obtained from fatty alcohols or the alcohols of spermaceti or sperm oil.  Instead of pyridine, trimethylamine or triethanolamine may be used.  The process may be applied to dyed or undyed material, and where dyeing has been effected with direct cotton colours, the dyestuff becomes fixed.
