Title: Improvements in and relating to the manufacture of succinimidobenzenesulphonamides and succinylaminobenzenesulphonamides
IPC: C07D417/12
Filed: 1945-07-04
Abstract: Succinimidobenzenesulphonamides are prepared by reacting succinimidobenzenesulphonyl chloride with (a) one molecular proportion of ammonia in presence of sufficient pyridine to combine with the hydrogen chloride formed; (b) one molecular proportion of an amino-substituted heterocyclic compound in the presence of sufficient pyridine to combine with the hydrogen chloride formed; or (c) two molecular proportions of an amino-substituted heterocyclic compound in an anhydrous inert solvent and in the absence of any other base. The resulting p  succinimidobenzenesulphonamides may be hydrolysed to the corresponding succinylaminobenzenesulphonamides.  In examples: (1) p-succinimidobenzenesulphonamide is obtained by adding one equivalent of ammonia to p - succinimidobenzenesulphonyl chloride dissolved in acetone and pyridine, and is then hydrolysed with caustic potash solution to succinylsulphanilamide; (2) p-succinimidobenzenesulphonamidopyridine is obtained by heating p-succinimidobenzenesulphonyl chloride with one equivalent of 2-aminopyridine dissolved in pyridine; (3) 2-(p-succinimidobenzenesulphonamido)-pyridine is made by heating p-succinimidobenzenesulphonyl chloride with two equivalents of 2-aminopyridine dissolved in benzene; (4) p-succinimidobenzenesulphonamidothiazole is made by heating p-succinimidobenzenesulphonyl chloride with two equivalents of 2-aminothiazole in benzene, and is hydrolysed to N4-succinylsulphathiazole by boiling with caustic potash; and (5) p-succinimidobenzenesulphonamidothiazole is prepared by heating p-succinimidobenzenesulphonyl chloride with one equivalent of 2-aminothiazole dissolved in pyridine, followed by hydrolysing with caustic potash to give succinylsulphathiazole.

IPC: B65H45/24
Filed: 1929-06-04
Abstract: 313,955. Schnellpressenfabrik Koenig & Bauer Akt.-Ges. June 20, 1928, [Convention date]. Feeding webs.-A paper web bearing regularly spaced printed impressions is fed to a cutting-apparatus by feeding devices operating to feed the web alternately at a speed higher and lower than the theoretically correct speed, the feed speed being selected automatically by detecting devices carried by control rollers between which the web passes and which cooperate with perforations or other register marks on the web. The invention is particularly applicable to apparatus for supplying inset sheets to the product of high speed printing- presses. In one form, Fig. 1, the previously printed and perforated web 1 passes over a control roller 7 and between feed rollers 3, 4 to the. cutting- devices 5, 6. The roller 7 is provided with two conducting strips 10, 11 separated by an insulating strip 9 and rotating opposite to the roller is a disc 8 carrving two spring-pressed contact pins 13, 14 co-operating with the strips 10, 11. When the web is in correct register, the perforations lie on the insulating strip 9 but if the feed is greater or less than normal a perforation lies on the strip 10 or 11 and an electric circuit is closed through the corresponding pin 13 or 14 to operate devices for contracting or expanding the diameter of the feed rollers 3, 4 and thus cause them to feed at a speed slightly lower or higher than the correct speed rollers. The pins 13, 14 extend beyond the periphery of the disc 8 so that they remain in contact with the strips for a time sufficient to ensure closure of the circuit at high speeds. In another form, Fig. 3, two pairs of feed rollers L3, L4 and L5, L6 are provided adapted respectively to feed at a slightly smaller and slightly greater speed than the correct speed and the upper rollers are mounted on a lever W. or are controlled by a sliding wedge member H, Fig. 4, so that only one pair of rollers are operative at one time. A pair of rollers L1, L2 feeds the web at approximately the correct speed into a loop in which floats a roller A, partly counterbalanced by a weight G, and from the loop the web passes between the control roller K and disc J similar to the roller 7 and disc 8 of Fig. 1. The rollers L3, L4 continue to feed the web until the retardation of the web causes the perforations to allow a circuit to be closed by the roller K and disc J to reverse the position of the lever W or wedge member H and allow the rollers L5, L6 to feed. The perforations then creep forward until the other circuit is closed by the roller K and disc J to again reverse, the lever W or member H and throw in the lower-speed feed rollers. To prevent backward movement of the web when it is released during the change over of the feed rollers, a pair of rollers B1, B2 carrying flywheels E1, E2 are provided which by their momentum continue to feed the web forward.

Abstract: 1,209,553. Capacitive storage arrangements. STANDARD TELEPHONES & CABLES Ltd. 10 April, 1968, No. 17375/68. Heading H3B. A bi-stable circuit comprises either two diodes 4, 5 in series, Fig. 1, or a varactor diode in series with a capacitor 10, Fig. 2, to which a unidirectional voltage source 1, 2 consisting of a steady potential with a superimposed A.C. component is connected, each varactor diode being shunted by a feedback circuit 6, 7 which develops a reverse bias sufficient to maintain the diode in its high A.C. impedance state when the diode is pulsed by a trigger pulse of one polarity at terminal 3, but develops a reverse bias insufficient to switch the diode to a high A.C. impedance state if the diode is brought to its low A.C. impedance state by a trigger pulse of opposite polarity. Each diode forms a variable capacitor, the capacitance value of which, and hence its A.C. impedance, is determined by the trigger pulse. In the case of a high A.C. impedance state, the feedback circuit 6, 7 maintains the potential conditions produced by the pulse. Each feedback circuit comprises a diode 8, 9 and a rectifying voltage multiplier. In the arrangement shown in Fig. 2, a resistor 11 shunts the varactor diode and provides a leakage path sufficient to disable the effects of the reverse bias when the diode is in a low A.C. impedance state. Circuit connections are described, Figs. 3 and 4 (not shown), which enable the bi-stable circuit to be used in a binary store with non-destructive read-out properties.

The sheet material 5, e.g. toffee, is carried on the slidable table 4 which is moved forwardly intermittently in timed sequence with a series of tubular cutting dies 15 mounted on a reciprocating carrier 14 so that the table is stationary during the cutting operation, the dies accumulating stacks of cut work pieces which are pushed in succession from the carrier by a member 21 which reciprocates across the upper ends of the dies. This member 21 comprises a rod or bar, the ends of which slide in cam tracks 23 in fixed side members 22 between which the die carrier is disposed. A work piece discharging shoot 20 is supported at one end by the die carrier and, at a position 20e, is hingedly supported so that it is rocked by the rise and fall of the carrier. A stripper or guide plate 18 having for each die an opening 19 through which the die passes with a narrow clearance is disposed transversely across the path of the die such that any extraneously adhering material on the dies is removed. A drum bar for holding the sheet down during the cutting operation is attached via rod 27 to a cam collar 28 surrounding cam 29 on the main driving shaft 7 so as to reciprocate in opposition to the die carrier. The cutting ends of the dies can be adjusted relatively to the work supporting surface of the table 4 by adjustably securing the die carrier to a back support 13 reciprocating in guides 16. The stroke of the table 4 in the work feeding direction may also be varied selectively.
