Title: Improvements in and relating to the production of benzoylbenzoic acid and anthraquinone derivatives
IPC: C07C51/363
Filed: 1931-09-17
Abstract: Halogenated benzoyl-o-benzoic acids; halogenanthraquinones 2-Benzoylbenzoic acid or a halogen derivative thereof is treated with a halogenating agent in a sulphuric acid medium, in the presence or not of a catalyst such as iodine.  The products may be ring-closed to give halogenanthraquinones, and, if desired, ring-closure may proceed without isolation of the halogenated acid.  The halogenanthraquinones may be isolated by fractional dilution of the sulphuric acid solution.  In examples, (1) 2-benzoylbenzoic acid is chlorinated in oleum (5 per cent) and in presence of iodine to give products of different chlorine content dependent on the duration of halogenation; these products are ring-closed by heating in 10 per cent oleum at 110-120 DEG  C., and details of the fractional isolation of one of the reaction-mixtures is also given wherein the concentrated sulphuric acid solution is diluted to 87,5 per cent strength, 85 per cent strength, and finally with excess of water to separate the isomers; (2) 4<1>-chloro-2-benzoylbenzoic acid is chlorinated in 90 per cent sulphuric acid in presence of iodine; the product is ring-closed in pure sulphuric acid at 160 DEG  C. and the solution diluted to 90 per cent strength in order to isolate 2-3-dichloranthraquinone.  The use of chlorsulphonic acid as a suitable medium is also mentioned.
Patent GB-708913-A (GB)
Title: Process for the oxidation of olefines
Inventor: MILLIDGE ALFRED FRANK
IPC: B01J19/24
Filed: 1950-10-26
Abstract: Epoxides are made by oxidizing olefines containing at least 3 C atoms in the molecule, and which are liquids at the oxidizing temperature of between 100 DEG  and 180 DEG  C. under the pressure used, in the liquid phase with molecular oxygen at least part of the mixture from the oxidation reaction being passed through a zone in which acids are removed before being recycled to the oxidizing zone.  Specified olefines are propylene, butenes preferably n-butenes, pentene-1 and -2, hexene-1, methyl pentene, heptenes and a - and b -di-isobutene. Acids may be removed by passing through a layer of solid neutralizing agents such as oxides or hydroxides of alkaline earths or through an aqueous medium in a separate extraction chamber.  The aqueous medium may contain alkali metal hydroxides or carbonates, or salts of weak acids. Dispersions of hydroxides or carbonates of alkaline earths may also be used.  Salts, e.g. chlorides, sulphates, or carbonates of alkali metals may be added to the aqueous alkaline medium so that the solubility of oxidation products other than acids is diminished.  A high concentration of salts is preferred as it leads to the retention of water in the medium.  Temperatures in the acid removal zone are preferably below those of oxidation, advantageously not above 50 DEG C.  Extraction may be effected by counter-current.  When the total liquid is treated it is preferred that the liquid be circulated at such rate that at least three times the volume contained in the oxidation reactors is circulated per hour.  Formic acid is preferentially removed with a solution of salts of acids which are weaker than formic acid, e.g. acetates.  Alkylene oxides may also be removed by the extracting medium and are recoverable therefrom by distillation; preferably under reduced pressure.  In examples: (1) butene is oxidized at about 50 atmos. and 120 DEG  C. in the presence of vanadium naphthenate and nitrogen, the oxidate being circulated up through cold aqueous potassium carbonate before returning to the reactor, a C4 epoxide being recovered from the total products; (2) is a repeat of (1) except that sodium carbonate is used instead of potassium carbonate and a suitable layout of apparatus is described. Methyl acetate, acetaldehyde, crotonaldehyde and methylethyl ketone are also produced in small quantities.  Formic, acetic and propionic acids are obtained from the aqueous carbonate solution.  The Provisional Specification describes the use of all lower olefines and specifies manganese as a catalyst in example 1 instead of vanadium naphthenate.

Abstract: 445,691. Cash registers. BURROUGHS ADDING MACHINE CO., 6071, 2nd Boulevard, Detroit, Michigan, U.S.A. Sept. 14, 1934, No. 26399. Convention date, Sept. 15, 1933. [Class 106 (i)] Cash drawer mechanism.-The cash drawer of a key-operated cash register is released either by depression of the keys or by the opening of a lockable lid giving access to a control lever settable to lock the machine or condition it for open or closed drawer operation. The invention is described as applied to the cash register forming the subject-matter of Specifications 445,540, 447,264 and 449,004, and provided with a cash drawer and latching means therefor forming the subject-matter of Specifications 444,246, [Group XXXIV], and 444,247, respectively. In this kind of machine, the depression of a key-lever 4 rocks a universal bail 11 counterclockwise, Fig. 2, about the key shaft 6, and permits a key coupler 19 to rock clockwise about the bail and take over a projection 26 on the depressed key. The return movement of the bail is utilized to release the cash drawer 30. The drawer is latched by a bolt 36 rockable to release the drawer and held in releasing position, while the drawer is open, by a locking arm 72. The bolt is operatively connected through a crank-arm 41 and lever 42 to a bell-crank 46, the horizontal arm 49 of which carries a byepass pawl 51 for cooperation with the bail 11. The bell-crank 46 is also rocked to release the drawer upon the opening of a lid 29 to give access to a control lever 100, a stud 62 on one of the lid hinges serving to depress a pitman 57 pivoted to the arm 49 of the bell-crank. The control lever. As shown in Fig. 2, the control lever 100 is in its intermediate or " Closed Drawer " position. In this position of the lever and with the drawer open, a hooked arm 92 of a lever 104 takes under a stud 93 of the key coupler 19 so that the latter is prevented from rocking clockwise and movement of the bail is restricted by the abutment with a stop 96 of a shoulder 94 of the coupler. Thus, operation of the machine is prevented while the drawer is open and partially depressed keys will not become coupled. Upon the closing of the drawer, a stud 81 on an arm 82 of the bell-crank 46 acts through an arm 83, resiliently connected to the lever 104, to rock the latter counterclockwise and thereby remove the hooked arm 92 from under the stud 93. The machine is now conditioned for operation. To condition the machine for " Open Drawer " operation, the control lever is rocked clockwise, an arm 102 on its lower end serving to rock the lever 104 counterclockwise to release the coupler. To lock the machine, the control lever is rocked counterclockwise, whereby an arm 106 thereon holds the lever 104 in the position shown with its hooked arm 92 below the stud 93 of the coupler.
