Title: Improvements in the manufacture and production of carboxylic acid amides
Filed: 1936-07-08
Abstract: Carboxylic amides are obtained by treating an aliphatic or cycloaliphatic hydrocarbon with carbamyl chloride or an alkylcarbamyl chloride in the presence of a Friedel-Crafts catalyst.  Specified hydrocarbons which may be treated are n- and iso-butane, hexanes, heptanes, octanes, octadecanes, butylene, decylene, octadecadiene, cyclopentane, cyclohexane, hexahydrotoluene, hexahydroxylenes, cyclohexene, abietiene, paraffin wax, petroleum jelly, benzines, ligroins, illuminating oils, and aliphatic or cycloaliphatic hydrocarbons obtainable by the condensation or polymerization of olefines or by the destructive hydrogenation of petroleum, coal, brown coal or peat. The carbamyl chloride and the catalyst may be taken separately, or use may be made of the molecular compounds of carbamyl chloride or alkylcarbamyl chlorides with Friedel-Crafts catalysts (cf. Specification 449,100).  In the examples, (1) n-pentane is heated with the molecular compound of carbamyl chloride and aluminium chloride to yield a caproic amide; n- or iso-butane and n-hexane may be similarly treated; (2) cyclohexane, treated as in example 1, yields 1 - methylcyclopentane - 2 - carboxylic acid amide. Methyl- and ethyl-carbamyl chlorides are also specified as reagents which may be used.

[Class 94 (i)] Filling-machines, of the kind comprising travelling hoppers arranged to rotate about a vertical axis and to receive vertical movement, co-operating with holders for bags &c. travelling in a concentric path, are arranged with the hoppers closed at the lower ends by swing doors normally closed by counterweights or springs, and opened by cam action at the appropriate times. A number of hoppers 21, 23 are rotated by arms 24, 25 about a spindle 12, and are mounted for vertical displacement by means of slide rods 31 and collars 30. On arrival beneath the funnel 37 of an automatic weighing-machine, the funnel 37 is moved by a cam 45 and the hoppers are maintained in contact therewith by a cam 34, a felt ring 38 affording a tight joint. A predetermined charge is delivered from a funnel 36 and passes into the hopper 21. The funnel 37 is raised and the hopper resumes its rotation and falls to the level indicated at 22 owing to the slope of the cam 34. At this position, the mouth of the hopper enters a bag &c. in a receptacle 16 on a bracket 14 rotated in synchronism with the hoppers about the axis 12. The lower end of the hopper is formed with a tapered lower edge 46, Fig. 3, to fit the top of the bag, and has two flaps 47, 48 adapted to be opened about their hinges 50, 51 by the action of a cam 57 on a roller 56 on an arm 55, to allow the charge to enter the bag. Parts of the cams 34, 57 are serrated to vibrate the hoppers and associated parts, and a semicircular plate 60 is vibrated by cams 64 to shake down the charges in the bags. The containers or holders 16, 19 may be four-sided or may be open-sided to allow the horizontal entry and exit of the bag. In another form, the containers may be curved round an elongated track with circular ends. The apparatus may be used in connection with the machine described in Specification 410,557.

Filed: 1954-07-05
Abstract: <PICT:0780981/III/1> <PICT:0780981/III/2> Articles are dry-cleaned in a closed container by saturating them with an organic solvent, then supplying to the container an aqueous detergent emulsion, measuring the relative humidity of the vapour in the container and cutting off the supply of detergent emulsion thereto when the relative humidity of the vapour reaches a predetermined value.  The container is then flushed with further organic solvent, drained, and the articles are finally dried.  In a suitable plant, the articles are immersed in a solvent in a drum 1, provided with a rotary cage or tines if desired, the solvent being supplied through a line 2 and being re-circulated by a pump 3 for flushing when desired.  The detergent emulsion is supplied to the drum from a tank 6 through line 7, valve 8 and an injector 9 mounted on the drum.  Compressed air is supplied through line 11 and valve 12 to the injector 9.  The valves 8 and 12 are balanced-pressure valves controlled by electro-magnetic devices which are energized to open the valves by a humidity control device 23. The injector 9 comprises a loaded piston valve with a detergent inlet 16, Fig. 2, a compressed air inlet 17, a spray nozzle 18 and a piston 19 with a conical valve 18b sliding therein and urged into the closed position by a spring 20.  In the closed position, the air raises the piston to open the detergent inlet 16, the detergent being thus sprayed by the compressed air through the nozzle 18 into the drum. The humidity-control device 23 open to the drum consists of a hygrometer having a vellum strip which alters its length according to the relative humidity of the vapour in the drum.  The vellum strip is connected to a contact close to a second contact, the contacts making electric contact to complete an electric circuit when the strip shortens in a dry atmosphere and separating when the strip lengthens in a moist atmosphere.  The hygrometer can be set to open the contacts at a selected relative humidity.  A time switch 28 can be set to open and close the hygrometer circuit for set time periods. The hygrometer 23 and switch 28 are connected to a mains circuit including current supply conduits 31 and a relay switch 32 connected to the energizing coils of the valves 8 and 12 respectively.  In a modification, the vellum strip may be coupled to a pneumatic control device connected to pneumatic valve-operating mechanism.
