Title: Improvements in and relating to wrapping machines
IPC: B65B41/14
Filed: 1934-06-06
Abstract: 426,453. Wrapping-machines. NATIONAL BREAD WRAPPING MACHINE CO., 132, Birnie Avenue, Springfield, Massachusetts, U.S.A. June 6, 1934, No. 16801. Convention date, June 6, 1933. [Class 94 (i)] Relates to a wrapping-machine having an article carrier with article feeding and article delivering means in spaced relation at the same side of the carrier, and a web supply on the opposite side of the carrier with means for guiding the web to the rear of the article contacting face of the carrier, and holding means for the leading end of the web, so that on the return movement of the carrier the web is drawn across the article receiving side of the carrier. According to the invention the web is drawn from the supply during the return movement of the carrier, after which severance takes place. The articles are fed to the machine by a series of pushers 15, Fig. 1, to a position in front of a plunger 16 which carries them, with the wrapping material, over a plate 18 and on to the bottom plate 19 of a vertically reciprocable carrier. The carrier reciprocates vertically on slides 21 between the position shown in Fig. 1, and one in which the plate 19 is level with the floor 24 of a wrapping and delivery channel. The paper &c. web w is fed from a roll 45 over a guide roll 48, drive roll 49, take-up roll 50 and guide roll 52. When the carrier is in its upper position, Fig. 6, the front edge of the web is engaged by grippers 71, 72, which draw it between rolls 56, 60 over the surface of a secondary plate 55, and beneath a roll 80. The grippers travel along a line 70 to the right a distance determined by the size of wrapper required. The stroke of the grippers can be varied without altering the terminal gripping position. The carrier now falls to the lower position, drawing out more paper, which is positioned by a stationary roll 73 and a roll 74 on the front edge of the carrier so as to lie between the carrier and the article in front of the plunger 16. Retrograde movement of the web is prevented by a spring 66 bearing upon the arms 62 carrying the roll 60. The position is now as shown in Fig. 8, and a knife 76 on a fixed portion of the machine enters a groove in an opposing member 75 on the carrier and serves the web. The weight of the roll 80 frees the leading edge of the web from the member 75. The plunger 16 moves to the left, and the wrapper is folded about three sides of the article, the top fold being made by an adjustably mounted plate 26 pivoted at 30 and brought down into a horizontal position when the carrier rises again. Members 25 on the carrier make the first end tucks. As the carrier rises, the fourth side fold is made by the end of the table 24. Folders 35, Fig. 1, make the second end tucks, and pushers 36 on a transporter 37 move the article over the table 24. The third and fourth end tucks are made by the side pieces 38 and slots 39 therein respectively, from which the package passes to sealing and delivery devices.

Title: New substituted phenyl phenyldithiocarbamates and process for the preparation thereof
Inventor: JACOB ROBERT MICHEL
IPC: C07C333/18
Filed: 1954-06-08
Abstract: The invention comprises substituted phenyl phenyl dithiocarbamates (or substituted phenyl phenyl amino-dithioformates) conforming to the formula <FORM:0760432/IV(b)/1> where X and X1 are the same or different and each represents a halogen atom or an alkoxy or substituted alkoxy, alkylthio or substituted alkylthio or dialkylamino group and the substituted phenyl radicals may be further substituted.  A process for the production of dithio carbamates comprises the interaction of a substituted phenyl isothiocyanate of the formula X-C6H4-NCS and a thiophenol of the formula X1-C6H4-SH, X and X1 being defined as above.  In examples, the 4-ethoxyphenyl 41 - ethoxyphenyldithiocarbamate is obtained by reacting 4-ethoxyphenyl isothiocyanate with 4-ethoxy-thiophenol (I); 4-n-butoxyphenyl 41-n-butoxyphenyl dithiocarbamate is obtained by reacting 4-n-butoxyphenyl isothiocyanate with 4-n-butoxythiophenol (II); 4 - n - butoxyphenyl 41-dimethylaminophenyl-dithiocarbamate is obtained by reacting 4-n-butoxythiophenol with 4-dimethylaminophenyl isothiocyanate (III); 4-chlorophenyl 41-chlorophenyl dithiocarbamate is obtained by reacting 4-chlorothiophenol with 4-chlorophenyl isothiocyanate (IV); 4-dimethylaminophenyl 41-dimethylaminophenyldithiocarbamate is obtained by reacting 4-dimethylamino thiophenol with 4 - dimethylaminophenyl isothiocyanate (V); 2 : 4 - dichlorophenyl 21 : 41 - dichlorophenyl dithiocarbamic acid is obtained by reacting 2 : 4 - dichlorothiophenol with 2 : 4 - dichlorophenyl isothiocyanate (VI); 4-(21-ethoxyethoxy) phenyl 41-(211-ethoxyethoxy) phenyl dithiocarbamate is obtained by reacting 4-(21-ethoxyethoxy) thiophenol with 4-(21-ethoxy-ethoxy) phenyl isothiocyanate (VII); and 4-ethyl thiophenyl 41-ethylthiophenyl dithiocarbamate is obtained by reacting 4-ethyl thiophenol with 4-ethylthiophenyl isothiocyanate (VIII); and comparable products are obtained using a thiophenol substituted in the 4-position by a hydroxyalkylthio, alkoxyalkylthio or alkylthioalkylthio group in the latter process.  Isothiocyanate starting materials are obtained in examples from the corresponding ammonium dithio-carbamates by desulphurizing with lead nitrate (II) or by reaction with phosgene (VII; VIII).  Thiophenol starting materials are obtained in examples by reduction of 4-butoxyphenylsulphonyl chloride with zinc (II) and from the corresponding anilines by the xanthate method (VII; VIII).

Filed: 1959-05-21
Abstract: The invention comprises 3 : 5-cyclo-6-oxo)-conanine of the formula <FORM:0884176/IV (b)/1> the corresponding 6-hydroxy compound, 3 : 5-cyclo-18-dimethylamino-20-pregnen-6-one and 18-dimethylamino-5 : 20-pregnadien-3b -ol.  They may be prepared as follows: conessine is converted to 3-dimethylamino-6-oxo-conanine (2 : 4-dinitrophenyl-hydrazone described) either directly by reduction with sodium borohydride and subsequent chromic anhydride oxidation of the boron compound thus obtained or indirectly by nitration to give 6-nitro-conessine and reaction of this with zinc and acetic acid, the 3-dimethylamino group is then quaternized selectively and the resulting quaternary salt, e.g. methotoluensulphonate or methiodide, treated with alcoholic alkali to yield 3 : 5-cyclo-6-oxo-conanine, this is quaternised, e.g. with methyl iodide, converted to the quaternary hydroxide or alkoxide and this heated to split off water or alcohol, e.g. by azeotropic distillation with toluene, to yield 3 : 5-cyclo-18-dimethylamino-20-pregnen-6-one.  This compound may also be prepared more directly by preparing the bis-quaternary salt, e.g. bis-methiodide or bis-methotoluenesulphonate, of 3-dimethylamino-6-oxo-conanine, converting this to the bis-quaternary hydroxide or corresponding alkoxide and heating this under anhydrous conditions.  Reduction of 3 : 5-cyclo-6-oxoconanine with an alkali metal aluminium hydride yields 3 : 5-cyclo-6-hydroxy-conanine (a mixture of the 6a - and 6b -isomers which can be separated by crystallization), this with formic acid gives 3-formyloxy-5-conenine, this on hydrolysis gives 3-hydroxy-5-conenine, this is converted to a quaternary salt, e.g. with methyl iodide, and then to the quaternary hydroxide or alkoxide and this on pyrolysis, e.g. in an aromatic hydrocarbon, yields 18-dimethylamino-5 : 20-pregnadien-3b -ol. Examples of all these processes are given and a list of salt-forming organic and inorganic acids and quaternizing agents is provided. Further examples describe (1) treatment of 18-dimethylamino-5 : 20-pregnadien-3b -ol with perbenzoic acid to yield the benzoic p acid salt of 3-hydroxy-18-dimethylamino-5 : 20-pregnadiene N-oxide, conversion of this to the free N-oxide, and treatment of this with a mixture of hydrochloric and acetic acids to give 3-hydroxy-18-dimethylamino-5-pregnen-20-one (the quaternary hydroxide of which, on heating, yields 18 : 20-epoxy-5 : 20-pregnadien-3-ol and a compound which is presumed to be 3-hydroxy-17 : 18-cyclo-5-pregnen-20-one) via, on complete acetylation, the 3-acetoxy compound; and (2) the osmylation of 3 : 5-cyclo-18-dimethylamino-20-pregnen-6-one to yield a mixture of the 20a -and 20b -epimers of 3 : 5-cyclo-18-dimethylamino-20 : 21-dihydroxy-pregnan-6-one.
