Title: Improvements in the synthesis of 1, 4-dicaffeylquinic acid
IPC: C07D307/00
Filed: 1955-12-05
Abstract: 1,4-Dicaffeyl-quinic acid is prepared by the condensation of (a) thionyl-caffeic acid chloride with quinide or a derivative thereof having the general formula <FORM:0810375/IV (b)/1> (wherein Z represents H and Q is H or a diacylcaffeyl or carbonylcaffeyl group); (b) thionylcaffeic acid chloride with quinic acid; and (c) a di-acyl- or carbonyl-caffeic acid chloride or anhydride with quinic acid, followed in every case by selective saponification of the resulting condensation product.  The condensation is preferably effected by mixing 1 to 4 mol(s) of the caffeic derivative with 4 to 1 mol(s) of the quinic acid or quinide derivative and heating the mixture at a temperature between 110 DEG  and 180 DEG  C. for 15 to 90 minutes, and the saponification achieved by treatment with 3 per cent barium hydroxide at between 0 DEG  and 30 DEG  C. for from 1 to 40 hours in the absence of air.  In examples, (1) carbonylcaffeyl chloride and quinic acid are heated under vacuum, cooled and the residue in acetone added to excess barium hydroxide solution under nitrogen yielding 1,4-dicaffeyl-quinic acid on acidification and crystallization from 55 per cent acetic acid; (2) thionylcaffeic acid chloride and quinide are condensed as in (1) to give 1,4-dicaffeylquinic acid, also prepared (3) from thionylcaffeic acid chloride and quinic acid.  Specification 810,376 also is referred to.

Abstract: 343,975. Toothed gearing ; positive clutches. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London.- (Western Electric Co., Inc.; 195, Broadway, New York, U.S.A.) Nov. 22,1929, No. 35860. [Classes 80 (i) and 80 (ii).] In a machine for punching statistical record cards, the press-head 63 is reciprocated vertically by links 61 pivoted to a rocking shaft 57 which carries an arm 56 oscillated by a cam 53. A second cam 45 on the same shaft 52 as the cam 53 oscillates the sector 37 for reciprocating the selector bars 31 by means of a lever 42, Fig. 4, and a rack 40 maintained in engagement with a pinion 39 on the sector shaft 38 by a roller 47. A movable contact 177, Fig. 2, for selecting the punches is oscillated at each revolution or the cam shaft 52 by means of rack-and-pinion gearing 178, 180, 182, 186, 188, Figs. 2 and 4, driven from the shaft 38. Rollers 189, 183 &c. are provided for keeping the racks and pinions in mesh. Single revolution clutch. On depression of a key the cam shaft 52 is caused to perform a single revolution and come to rest, the rotation being derived from a continuously rotating toothed disc 146, Fig. 2, driven through worm gearing 144 and a pulley 141 from an electric motor (not shown). The shaft 52 has secured thereto a collar 151, Fig. 7, to which is pivoted a member 148 carrying a wedge 152 resiliently pressed upwards by a spring 153 and adapted for engagement with the teeth of the disc 146. A spring 149 tends to urge the wedge against the disc, but is normally prevented from acting by a lever 161, Figs. 2 and 7, carrying a surface 170 engaging a pin 154 on the member 148. A detent 160 holds the lever 161 in this position, but on depressing the key on electromagnet 156 is energized to withdraw the detent, against the action of a spring 159, and allow the wedge 152 to engage the disc 146. Before a revolution of the shaft 52 is completed the pin 154 engages a second surface 162 on the lever 161 and moves the lever into position to be locked by the detent 160, whereupon further rotation causes the pin 154 to engage the surface 170 and withdraw the wedge from the disc 146. Specification 343,919, [Group VIII], is referred to.

Title: Improvements relating to the production of bags and like containers
IPC: B65D5/18
Filed: 1956-11-27
Abstract: 854,499. Making bags. BERGHGRACHT, M. Nov. 27, 1956 [Nov. 28, 1955], No. 36245/56. Class 94(2). Bags of the kind made by folding a blank to U-shape and heat sealing the side margins are formed by a mandrel pressing blanks through a fixed die, the portion of the blank for forming the bag bottom being engaged by a second mandrel to shape the bottom as both mandrels travel with the blank through the die. The side margins are sealed when the blank leaves the die. In one embodiment, a web 1 of thermoplastic coated single or multiple ply sheet material is fed over the die 5 and a blank 4 cut off. An upper mandrel 7, the base of which may be shaped as in Figs. 10, 11 to produce the bottom formation shown in Fig. 1, presses the blank into the die, the blanks side margins entering opposed slots therein. A lower mandrel 10, shaped as in Figs. 12, 13 co-operates with the mandrel 7 as the latter descends. Heat sealing rollers 13, 13<SP>1</SP> grip the emerging folded blank, enabling the mandrel 7 to be withdrawn, and pass the blank downwards while sealing its side margins. At the same time rotary cutters (not shown) trim off surplus material. Both mandrels withdraw and an air jet from a nozzle 16 blows the completed bag onto a discharge shoot 17. In another embodiment, Figs. 18 and 20 (not shown), the mandrels move horizontally between opposed guiding rollers. The side seams are formed by upper and lower heated bars, the upper bars being carried on a vertically movable plate. The bars may be profiled to allow for variations of seam thickness. The die has four sections moveable towards or away from each other by screw adjustment to allow for various thicknesses of material. Resilient rollers are mounted on the die sections to press the blank against the four longitudinal side edges of the mandrels. In the formation of bags in which the corner points extend inwards, the mandrel 10 has a formation similar to that of the mandrel 7 as shown in Fig. 11, while the mandrel 7 is shaped to complement it.

Abstract: 1,208,490. Collapsible containers. DIAMOND INTERNATIONAL CORP. 30 July, 1968 [14 Aug., 1967], No. 36268/68. Heading B8D. [Also in Division F1] In order to prevent removal of a closure member from a container without visible damage in order to prevent unauthorized refilling, the closure member is drawn on to the container by interengaging screw threads until an internal bead in the closure member is forced over an external bead on a neck of the container, whereafter the threads disengage and the closure member is urged downwardly by camming surfaces associated with the beads. As shown, a collapsible polyethylene container has a neck formed with a frusto-conical end portion 56a and a bead 56, and a closure cap 20 has an internal bead 58 and an annular rigid stopper member 66 snugly received in the mouth 14  of the neck. The cap and neck have multistart threads whereby the cap can be drawn on to the neck until the crests of the beads have passed each other, whereupon the threads disengage and the neck bead 56 engages a conical surface 58b of the cap, so that the cap is urged downwardly to axially separate the threads. The dimensions are such that the neck is still radially compressed after the beads have snapped past each other, so that the neck is pressed into sealing engagement with the cap at 16 and, due to the conical shape of the neck, the mouth is contracted to seal against the stopper 66. A rigid casing permitting ingress of air is connectible to the cap for supporting the collapsible container, and a dispensing pump-plunger is positioned within the stopper 66.
