Title: Improvements in or relating to vulcanization accelerators and method of making the same
IPC: C08L61/22
Filed: 1926-09-13
Abstract: 259,933. Naugatuck Chemical Co., (Assignees of Cadwell, S. M., and Maximoff, A. T.). Oct. 15, 1925, [Convention date]. Condensation products of aldehydes and nitrogen compounds.-Products having the property of accelerating the vulcanization of indiarubber are obtained by condensing an aldehyde and a basic nitrogenous material at a temperature which initially and throughout the reaction is above 100‹ C; the preferred temperature is 135-145‹ C. The reaction may be begun by heating one of the components to the reaction temperature and then adding the other, and may be carried out under increased pressure. An addition of acid may be made when the nitrogenous material is strongly basic. The products may be improved by prolonged heating or by steam distillation for the removal of impurities. According to an example, heptaldehyde (2 mols.) is heated to 140‹ C. in a closed vessel and aniline (1 mol.) is slowly added. The pressure developed in the vessel is maintained for 30 minutes after the addition of the aniline, whereafter the water formed in the reaction is allowed to escape. The product may be heated at 135-145‹ C. for about 20 hours or the impurities may be removed by steam distillation. Heptaldehyde and aniline in equimolecular proportions may be similarly condensed. Another example describes the condensation of heptaldehyde and ammonia, and reference is made also to the manufacture of products from acetaldehyde and aniline, butyraldehyde and aniline, aldol and aniline, nonaldehyde and aniline, and heptaldehyde and ethylamine, p-toluidine, benzidine, pphenylenediamine, p-aminodimethylaniline, and urea. Specification 180,978 is referred to.

Patent GB-987116-A (GB)
Title: Improvements in or relating to bookbinding
Inventor: ADAMS SIDNEY GEORGE WILLIAM
IPC: B42B5/10
Filed: 1960-06-29
Abstract: 987,116. Bending. JAMES BURN & CO. Ltd. March 28, 1961 [June 29, 1960], No. 22802/60. Heading B3E. [Also in Divisions B6 and B8] A stack of perforated sheets is bound together by means of a wire element 10 comprising a wire member initially bent to form open rings or prongs 12 having re-entrant portions 16 and connected by straight portions 13, as illustrated on the left-hand side of Fig. 1. The binding elements are fed forwardly step-by-step to a bookbinding machine by means of parallel strips 18 frictionally engaged between the legs of some of the prongs. The foremost element is lifted clear of the strips 18 by a pad 30 and into engagement with a spring-loaded pad 31. The element comes to rest opposite the gap between jaws 22, 23 and is retained in this position by projections 33 on the member 32 engaging between the legs of the prongs. The next element on the strips 18 is held in position by vertically movable fingers 28. The member 32 is advanced to position the raised element between the jaws 22, 23, with its upper forward edge abutting a vertically slidable member 39. At the same time, the fingers 28 are lowered and the strips 18 advanced whereby spring-loaded bars 34,. 35 depending from the lower edge of the member 32, maintain said next element in its correct position as it is brought between the pads 30, 31. A stack of sheets is placed on the table 37 with its perforated edge resting on the portions 13 of the raised element, the projections 33 forming a back stop for the stack. The lower jaw 22 and the rear portion 38 of the table are raised whereby the prongs are pressed against the upper fixed jaws 23 and bent about their reentrant portion 16 to close the rings (see righthand portion of Fig. 1) and bind the stack together. The strips 18 are advanced by means of two comb-shaped members 26 movable relative to each other to grip the strips therebetween and rotatable about a pivot 46 to feed the strips forwardly. As described and claimed in co-pending Specification 987,117, the binding elements may be carried by flexible plastic strips arranged end-on between the legs of some of the prongs and wound into roll form. Paper is interleaved between the convolutions of the roll to prevent the elements from interfering with each other. The strips pass through guides after leaving the binding station which turn them through 90 degrees to enable them to be wound on to a take-up spool. Alternatively, the strips comprise endless bands passing around a pair of intermittently rotated drums, the upper runs of the strips passing through gudes before reaching the binding station which turn them through 90 degrees to their end-on positions. The binding elements are placed on the end-on strips by hand. After leaving the binding station the strips are returned to their original positions to pass around said drums.

Abstract: The invention comprises compounds of the formul : <FORM:0777681/IV(b)/1> <FORM:0777681/IV(b)/2> wherein R is hydroxyl or keto, R1 is an unsaturated aliphatic hydrocarbon radical, and R11 is a substituted or unsubstituted unsaturated aliphatic hydrocarbon radical, and which contain in position 7 in I either a divalent group or a pair of univalent groups which yield a keto group on acid hydrolysis, and in II a single univalent group convertible to keto on acid hydrolysis.  The invention also comprises the corresponding 7-keto compounds (III), their preparation by acid hydrolysis of compounds I or II, and a process for the preparation of compounds having in ring C the structure: <FORM:0777681/IV(b)/3> by reacting the corresponding 1-keto compounds with an unsaturated aliphatic metallo-organic compound, and hydrolysing the reaction product. Rings A and B can be substituted by hydroxy, acyloxy, alkyl, ether and ketal groups.  Specified groups in the 7-position of compounds I and II are ethylene dioxy, ethylene dithioketal, ethylene hemi-thioketal, dimethyl ketal or ethyl enol ether.  In examples: (1) 2,4b - dimethyl - 2 - methallyl - 7 - ethylenedioxy - 1,2,3,4,4a,4b,5,6,7,8,10,10a - dodecahydrophenanthrene - 1,4 - dione (IV) is added to ethoxyacetylene magnesium bromide in benzene and the product decomposed with ice-water, yielding 1-ethoxyethinyl - 2,4b - dimethyl - 2-methallyl - 7 - ethylenedioxy - 1,2,3,4,4a,4b,5,6,7,8,10,10a - dodecahydrophenanthrene - 1 - ol-4-one.  Similarly, using a stereoisomer of IV, two stereochemical modifications of the 1-ethoxyethinyl derivative are obtained.
