Patent GB-580509-A (GB)
Title: Process for the manufacture of pantothenic acid and its salts
IPC: C07C233/46
Filed: 1944-08-09
Abstract: Pantothenic acid is prepared by the action on d(+)-a  : g -dihydroxy-b b -dimethyl butyric acid-(3 : 31-dihydroxybutyl) amide or its derivatives diacylated in the acid radical of oxidizing agents which can be employed for the transformation of a glycol into the corresponding carboxylic acid containing one carbon atom less.  For this purpose, permanganic acid and its salts are particularly suitable.  If there are employed oxidizing agents such as periodic acid or lead tetra-acetate which can be employed for the oxidation of a diglycol with adjacent hydroxy groups, one of which is terminal to the corresponding aldehyde containing one carbon atom less there may be obtained as an intermediate product d(+)-a  : g -dihydroxy-b b -dimethyl-butyric acid-(31-oxopropyl)-amide.  The further oxidation of this compound to pantothenic acid is preferably carried out with silver oxide in the presence of alkali metal or alkaline earth metal hydroxides.  In examples: (1) d(+)-a  : g -Dihydroxy-b b -dimethyl-butyric acid-(31-41-dihydroxybutyl) amide is treated with barium permanganate in the presence of dilute aqueous sulphuric acid at 15-20 DEG  C., and the reaction product worked up to give pantothenic acid which is separated in the form of its cinchonidine salt.  Instead of the chonidine salt, the benzyl-thiuronium salt may be prepared.  (2) d(+)-a  : g -Dihydroxy - b b  - dimethyl - butyric acid - (31 : 41-dihydroxybutyl) amide is treated with barium permanganate in aqueous solution in the presence of precipitated barium carbonate to give the barium salt of pantothenic acid.  (3) d(+) - a  : g  - Dihydroxy - b b  - dimethyl - butyric acid-(31 : 41-dihydroxybutyl)-amide is treated with aqueous potassium periodate at a temperature below 30 DEG  C. to give a  : g -dihydroxy-b b -dimethyl-butyric acid-(31-oxypropyl)-amide.  This compound is mixed with silver oxide and treated with saturated aqueous barium hydroxide to form barium d(+)-pantothenate, which is purified by means of its benzyl-thiuronium salt.  In the silver oxide oxidation calcium hydroxide may be used instead of barium hydroxide to form the corresponding calcium salt.  (4) d-a  : g -Dihydroxy-b b -dimethyl-butyric acid-(31 : 41-dihydroxybutyl) amide is treated with 10 per cent aqueous periodic acid solution, and then neutralized with barium carbonate to form d - (+) - a  : g  - dihydroxy - b b  - dimethyl - butyric acid-(31-oxopropyl) amide which is then converted into pantothenic acid as in example (3).  Specification 568,355 is referred to.

Title: Materials soluble in water for use as fungicides
Filed: 1924-06-24
Abstract: Soluble fungicides in dry form, to be dissolved in water for treating plants or seed grain, are prepared by mixing a mercuric salt, such as the chloride, with a soluble dry salt-like derivative of an oxyaryl compound, such as sodium phenolate, sodium salt of cresol, or like compounds of naphthol, chlorophenol &c.  Sodium chloride or other salt may be added to increase the solubility of the preparation.  It is stated that no mercury is precipitated on solution in water. Compounds prepared by boiling together phenols and mercuric chloride in aqueous solution with the addition of an acid or an alkali are also referred to.

Digital decoding apparatus for use with a, code-bearing element bearing characters consisting of n, units of one of x variations of unit, in n columns, comprises n, pecker-operated switches corresponding to the respective columns of the code, each. switch having x<SP>n</SP> possible connections divided into groups of x<SP>n</SP>-<SP>1</SP> each, one group being of " made " connections, and the other or others of " unmade " connections, interconnections between the switches being such that in any switch its group of " made " connections corresponds to one of the types of unit, and its group or groups of " unmade " connections corresponds to the other type or types of units, a reading device for reading individually the units in each column and pecked means under the control of the reading device for actuating when necessary each switch to a " made " or " unmade position according to and in the presence of a given type of unit in the column corresponding to that switch. In Fig. 1 a five-column binary code is used to control thirty-two separate devices through five relays 0 to 4, each relay being actuated by a reading device from signals from one column of the code. Each relay switch has thirty-two possible connections divided into two groups of sixteen each arranged so that when one group is " made the other group is " unmade." Interconnection between the relays switches is such that for any position of the relays only one connection is made through the circuit. As shown, the relays are energized to select line 21. In Fig. 2, three control peckers 0<SP>11</SP>, 1<SP>11</SP>, 2<SP>11</SP> are each actuated by a reading device and complete either one of two groups of interconnections. Thus pecker 0<SP>11</SP> may make the connection on line A or line B, and peckers 1<SP>11</SP>, 2<SP>11</SP> control connections on lines C, D, and E, F, respectively. As shown, the circuit is operated for character 2 of the code shown, and thus relay 2<SP>1</SP> is the only relay unenergized and its switch remains closed. The arrangement is such that for each code character only one normally closed relay switch will remain closed and only the device in that switch circuit will be operated.

A valve structure, operative in response to an electrical signal from an inertia type skidsensing unit (K, Fig. 2, not shown) for cutting off a supply of compressed air from a distributer (C, Fig. 1, not shown) to brake actuators on a vehicle and releasing air from the brake actuators to regulate the pressure therein as necessary upon the occurrence of an incipient skid, comprises a relay valve unit B and an electromagnetic valve unit G, the relay valve unit comprising a closure member 84, which is normally held off a seat 85 by the action of a spring 76 on a relay piston 75 acting on the closure member by way of a hollow stem 82 providing an exhaust passage, while the electromagnetic unit comprises a valve disc 56 adapted to be lifted off a seat 58 and engaged with a second seat, to close an exhaust passage 69, when winding G1 is energized, thus admitting air from inlet chamber 90, via passages 65 and 68 in mating projections 67, 72 provided on the relay valve and electromagnetic valve units, to a chamber 80 where it acts on the relay piston 75 in opposition to the spring 76 to allow closure member 84 to seat and subsequently exhaust air from outlet chamber 88 via tubular stem 82 and filter 78. The armature 52 of the electromagnet is provided with a stem 54 the lower part of which is of reduced diameter whereby, upon de-energizing the coil G1 and consequent re-engagement of the valve disc 56 with the seat 58, air is exhausted from the chamber 80, allowing spring 76 to again move the closure member 84 off the seat 85. Closure member 84 is loaded by a light spring 86.
