Filed: 1962-05-16
Abstract: 933,369. Rotary printing machines. SOC. D'ETUDES DE MACHINES SPECIALES. May 16, 1962 [May 19, 1961; April 6, 1962], No. 18829/62. Class 100 (2). [Also in GroupXXXV] A paper web 1 travels through a number of cylinders A, B, for multi-colour printing. reference marks m being applied to the web at regular intervals by a preliminary marking device I. Photo-electric or electromagnetic detectors 11 are associated with the marks m, whilst a mark m 1  on each cylinder 2 is detected by device 13. The detectors 11, 13 are connected to comparator 14 the output of which controls servomotor 8 coupled to differential 6 through which the printing cylinder is driven. If the passage of reference mark m 1  is detected first, a signal is applied to bi-stable multivibrator 22 which produces a high-voltage signal at 22a. At the same time, a highvoltage signal is produced at the output 21b of monostable multivibrator 21, so that gate 24 produces a signal whose duration corresponds to the period between the passage of the marks past their corresponding detectors. This signal is applied to control device 20 for servomotor 8 to synchronize the two marks. If the paper web 1 leads the cylinder 2 so that mark m is detected in advance, gate 23 is opened by high-voltage signals applied to terminals 23a, 23b. This gate delivers an output signal which lasts until multivibrator 22 is operated by the passage of mark m 1 . The duration of the gate output signal is again equal to the period between the passage of the marks past their respective detectors. The multivibrator 21 is reset after a predetermined period, the multivibrator 22 being reset at the same time. The output signals from the gates 23, 24 may control a brake on the cylinder 2.

Title: Mercapto-terminated liquid polymer
IPC: C08G18/10
Filed: 1959-06-03
Abstract: The invention comprises a polymercaptan, liquid at room temperature, composed of linear polyester condensation polymer chains, the ends of said chains being connected with aliphatic mercapto radicals through links selected from thiourethane and urea links.  Such a product (which is curable by oxidation) is prepared by reacting a hydroxy-terminated polyester condensation polymer with an amount of an organic diisocyanate such that the number of isocyanate groups exceeds the number of hydroxy groups in the reaction mixture, whereby isocyanate terminals are formed on the polymer and then reacting the resulting isocyanate terminated polymer with an amount of an organic mercaptan selected from dimercaptans and mercaptoamines such that the number of mercapto groups in the dimercaptan or of mercapto and amino groups in the mercapto-amine exceeds the number of isocyanate groups in the reaction mixture.  (The amino group of the mercaptoamine or one of the sulphydryl groups of the dimercaptan reacts with the terminal isocyanate groups to give a urea or thiouretane linkage through which the sulphydryl group is connected to the chain.)  When a mercaptoamine is used the polyester is preferably prepared from reactants that include a trihydric alcohol.  For the preparation of the polyester glycol, diethylene glycol, glycerol, sorbitol, pentaerythritol, trimethylol-propane or ethane; amino alcohols; and oxalic, adipic, sebacic, 6-aminocaproic, phthalic, isophthalic, terephthalic, malonic, succinic, maleic, fumaric, dimer and itaconic acids are specified.  Arylene, alkylene and cyclohexylene diisocyanates are listed.  Ethane dithiol, bis-beta-mercapto-ethyl sulphide or the polythio-mercaptan polymers (m.wt. 500-1500) disclosed in U.S.A. Specification 2,466,963 are suitable dimercaptans. Mercapto-ethylamine, propylamines and butylamine are the preferred mercaptoamines.  In typical Examples: (1) a mixture of polyesters from triethylene glycol and ethylene glycol, respectively, and adipic acid is reacted with excess 2,4-toluene diisocyanate and the NCO-containing product is reacted with excess ethanedithiol in the presence of 2-methylpyrrolidone as catalyst. Samples of the mercapto-terminated product are cured in admixture with (a) magnesium oxide, stearic acid and tertiary butyl hydroperoxide; (b) carbon black and tertiary butyl peroxide; (7) a mercapto-terminated polymer is obtained in a similar manner from diethylene glycol/trimethylol propane/adipic acid polyester, 2,4-toluene diisocyanate and mercapto-ethylamine.

Title: Process for making unsaturated ethers
Filed: 1949-07-20
Abstract: 1-Alkenyl ethers are made by passing a gaseous mixture of a primary or secondary aliphatic monohydric alcohol and either a 1-alkenyl ether of a primary alkanol different from said alcohol or a dialkyl acetal of said alkanol over an acetal-splitting catalyst at 250-450 DEG  C., preferably 250-350 DEG  C.  As the reaction does not go to completion, fresh ether or acetal may be added and the products recycled.  The preferred catalyst is diatomaceous earth, treated if necessary to make it alkaline in reaction, i.e. so that its aqueous extract has a pH of 8 or more; literature references are given to other suitable catalysts.  Examples show the preparation of the following vinyl ethers: ethyl, butyl, hexyl, 1 : 3-dimethylbutyl, 2-ethylhexyl and 1-methyl-4-ethyloctyl, and also of 1-butenyl methyl ether.  In general the starting materials are R-CH=CH-OR1 and R2OH, where R is H or alkyl, such as methyl, ethyl, propyl, butyl or octyl, R1 is primary alkyl and R2 is the residue of a primary or secondary aliphatic monohydric alcohol. Suitable alcohols R2OH are methanol, ethanol, isopropanol, butanol, sec.-butanol, pentanol, hexanol, heptanol, octanol, nonanol, decanol, undecanol, lauryl alcohol, and the methyl, ethyl and butyl mono-ethers of mono- and diethylene glycol.  When an acetal is used, the group R1 is preferably a primary alkyl group of 1-4 carbon atoms.  The Specification as open to inspection under Sect. 91 mentions also cyclopentanol, cyclohexanol, furfuryl alcohol and tetrahydrofurfuryl alcohol as suitable for R2OH. This subject-matter does not appear in the Specification as accepted.ALSO:Catalysts for the production of alkenyl ethers R - CH = CH - OR2 from alcohols R2OH and ethers R - CH = CH - OR1 or the corresponding acetals comprise diatomaceous earth treated with a dilute (e.g. 2 per cent) aqueous solution of an alkali or alkaline earth metal hydroxide so that the aqueous extract of the earth has a pH of at least 8.  In the above formul , R is H or alkyl, R1 is primary alkyl and R2 is primary or secondary alkyl different from R1.

Aug. 14, 1951, No. 19165/51. Class 135. A pressure relief valve comprises a main valve controlled by a pilot valve, the main valve including a body 10, Fig. 1, with inlet and outlet 11, 12 respectively, a seat 14 surrounding the inlet, a closure member comprising a rigid disc 18, a weight 26 and an annular sealing member 24 clamped on its inner periphery between the disc 18 and weight 26, and on its outer periphery between the disc and a ring 21, the closure member being supported in the body by a diaphragm 19. Inlet pressure acts through passages 28, 27 in a chamber 29 on the upper side of the diaphragm and also through grooves 32, 30 and 31 in the space between the member 24 and disc 18 whereby with normal operating pressure in the inlet, the member 24 is urged to seal with seat 14 while the disc floats above the seat. The pilot valve comprises a closure member 54 controlling release of pressure from chamber 29 to atmosphere through screened outlet 61, and actuated by a diaphragm 36 through a spring-loaded rod 44 which is guided by spring fingers 62. A chamber 39 beneath the diaphragm is open to inlet pressure through a pipe 41. Thus, when inlet pressure exceeds a predetermined value, the pilot valve opens to vent the chamber 29 and then the main valve opens. A supplemental relief valve 66, Fig. 3, of the kind described in Specification 693,953 has its inlet 72, connected to the chamber 29, and is operable to vent chamber 29 at a higher pressure than does the pilot valve, and therefor only operates if the pilot valve breaks down, e.g., due to puncturing of diaphragm 36. The closure member of valve 66 comprises a weight 69 and a sealing member 69a sealed thereto by a ring 68, inlet pressure acting, through a hole 78, in the space between the members to support weight 69 in a floating condition and to urge member 69a to seal against the seat, the closure member being supported by a diaphragm 67. The outlet of the valve is a restricted orifice 74 of larger area than passages 27, 28, and when the valve opens, pressure builds up in outlet chamber 73 and acts on diaphragm to quickly open the valve fully. The pneumatic chambers formed in the closure members of the main and supplemental valves prevent closing shocks.
