Patent GB-579971-A (GB)
Title: Improvements in or relating to the preparation of dithiol compounds
Filed: 1942-03-24
Abstract: Dithiol compounds which are valuable as inhibitors for the toxic effects of trivalent arsenical compounds are prepared by reacting a compound of the general formula <FORM:0579971/IV/1> with an alkali hydrosulphide characterised in that the reaction is carried out at room temperature or in a closed system at higher temperatures.  In the formula R may be hydrogen alkyl or aralkyl and R1 may be CX(R)2 or C(R)2.CX(R)2, and X is halogen.  In examples: (1) 2 : 3-dibromopropanol is added to a solution of sodium in alcohol which has been saturated with dry hydrogen sulphide, and allowed to stand a week at room temperature.  The product is acidified with hydrochloric acid and extracted with chloroform to give 2 : 3-dimercapto-propanol; (2) dibrompropyl methyl ether is added to alcoholic sodium hydrosulphide prepared as in example (1) and the product similarly worked up to give 2 : 3-dimercapto propyl methyl ether; (3) dibrompropane is added to alcoholic sodium hydrosulphide as before and the mixture heated in a sealed tube for 16 hours at 80-100 DEG C. and worked up by treatment with caustic soda and then as in example (1) to form 1 : 3-dimercaptopropane; (4) dibrompropylamine hydrochloride is heated with methyl alcoholic ammonium hydrosulphide in a sealed vessel at 80 DEG  C. for 12 hours.  The product is evaporated in vacuo and taken up in chloroform to give 2 : 3-dimercaptopropylamine.  A number of experiments are described to illustrate the value of the compounds of the present invention as inhibitors of the toxic effect of trivalent arsenic compounds.  The dithiols may be applied by inunction injection or oral administration.  Conveniently an inhibitor is prepared from a dithiol compound prepared according to the present invention composited with a vehicle which may be a volatile solvent, a solvent oil or an ointment base such as lanoline.ALSO:Dithiol compounds having the general formula <FORM:0579971/VI/1> where R denotes hydrogen, alkyl or aralkyl and R1 denotes -c.SH(R)2 or -c(R)2.c.  SH(R)2 are valuable as inhibitors for the toxic effects of trivalent arsenical compounds. The dithiol compounds may be applied by inunction, injection or oral administration.  A convenient method of applying the dithiols is in combination with a vehicle which may be a volatile solvent, a solvent oil or an ointment base such as lanoline.  A number of experiments are described to illustrate the value of the dithiol compounds as inhibitors.

Title: Improvements in or relating to manufacture of pipes by spinning
Inventor: RILEY RALPH VICTOR
IPC: B29C70/32
Filed: 1954-02-11
Abstract: <PICT:0767209/III/1> <PICT:0767209/III/2> Woven glass fibre cloth 11 is wound on a mandrel comprising a cardboard sleeve 12 on a roller 13, either helically or circumferentially.  The fibre-coated sleeve is removed from the roller and inserted into the pipe 14 to be lined or the roller may also be inserted and then removed.  Metal rings 15, of suitable dimensions to fit inside the pipe and outside the sleeve, are inserted against the edges of the glass cloth 11.  The pipe is mounted on rollers 16 and rotated by a roller 18, driven from a motor 20, at a speed sufficient to cause the cloth 11 to expand off the sleeve 12 and cling to the inside of the pipe.  The pipe is then stopped and the cardboard sleeve withdrawn.  The pipe is rotated again at the same speed while synthetic resin is poured in through a trough in a manner to distribute it evenly, and rotation is continued until the fibre 11 is thoroughly impregnated with the resin.  If the resin is cold-setting polyester resin, which advantageously contains 1 per cent oleic acid, it cures without external heat.  If hot-curing polyester resin mixture is used external heating may be supplied by burners, which, unless a flame shield is fitted, should not be lit until the pipe is rotating as the liquid resin is inflammable. The plastic material may be in suspension or emulsion with water or an organic liquid, the suspension liquid being eliminated during the spinning.  This method may be used to produce pipe linings which are either solid or porous.  Porous linings may also be produced by using a plastic material in the form of a foam with air, carbon dioxide or similar inert gas.  The glass fibre reinforcement, instead of being wound on a mandrel, may be previously knitted as a tube.  Heating, where required, may be by electricity, steam or hot water.

Patent GB-613938-A (GB)
Title: Improvements in and relating to the removal of liquids from liquid-containing systems
IPC: G01N1/20
Filed: 1946-02-11
Abstract: Samples or portions of predetermined volume are removed from a main stream of liquid by diverting the stream to a vessel of volume adequate to hold the portion required, the vessel being provided with (a) an overflow from which the liquid normally returns to the main stream; (b) a conduit leading to a sampling or off-take receiver; (c) a connection to a source of pressure (gas), the connections being arranged so that on application of pressure (1) flow from <PICT:0613938/III/1> the main stream ceases; (2) the portion or part thereof collected in the vessel is driven over into the collecting receiver. Automatic operation to remove samples at predetermined intervals is provided.  The process is described with reference to a distillation process carried out in a column 1 provided with an off-take 3 cooled by condenser 2 so that condensate formed is fed through line 5 to a vessel 4 from which the condensate returns normally through line 6 to the column 1 as reflux.  The vessel 4 is provided with a central baffle plate 7, a U tube 8 leading through line 9 to the sampling receiver 27, and a pipe 10 through which the gaseous pressure agent is supplied.  The pipe 10 is connected (a) to a tube 24 through which nitrogen is supplied through a sulphuric acid bubbler 22 and trap 23; (b) to a lute 25 provided with a variable head of liquid which can be varied in height according to the quantity of sample required; (c) by a bent end portion so as to dip into a U tube 11 filled with mercury 12 and provided with a glass float 14 containing a soft iron armature 17, the corresponding part of the U tube being surrounded by a solenoid 18 connected into an electrical circuit 19 closed by tilting a mercury switch 20.  On closing the circuit, the solenoid is energized and depresses the float 16, thus causing the mercury to flow up the limb of the U tube and close the end of pipe 10. The pressurizing gas is thus forced to flow into the vessel 4, whereupon flow of condensate through pipe 5 ceases and the sample collected in vessel 4 is evacuated into the receiver 27.
