Class 100(2) A method of printing designs on lengths of textile materials comprises intermittently advancing the material over an evenly upwardly and subsequently downwardly inclined support serving as a printing table, applying colour to stencils above the support, and distributing the colour by doctors moving to and fro over the stencils during the stationary periods of the materials. An intermediate grey cotton cloth web 4 and a textile web 7 are fed intermittently by an endless rubber belt 3 over an arched printing table 2, and the web 7 then passes through a drying chamber 8. Over the table are located a number of stencil frames 11. Each frame carries a flat stencil, and for each stencil there is provided a doctor device 16 comprising a colour holder supplied by a flexible conduit 18 and tapering into a narrow edge contacting the stencil and provided with a colour slit with upwardly bent lips, which are closed when the doctor moves on to the non-design edge portion of the stencil. The doctor devices are linkd by couplings and reciprocated over their respective stencils while the web is stationary, thereby causing a tilting of the stencils to maintain linear contact with the screen. All the frames are lifted off the cloth after a printing by cam plates 13<1> and lifter rods 13. The table 2 may be replaced by a rotatable drum, round substantially the entire surface of which the webs are passed, the lower part of the drum being accommodated in a recess in the ground, and in this form the stencil frames are separately liftable after printing by cam plates and lifter rods.

Title: Improvements in valves
Inventor: MANLEY ROGER EDWARD WENTWORTH
IPC: A61M16/00
Filed: 1960-07-19
Abstract: 908,974. Respiratory appliances. BLEASE ANAESTHETIC EQUIPMENT Ltd. July 19, 1961 [July 19, 1960], No. 25166/60. Class 81 (2). In anaesthetic or forced breathing apparatus the inhalation and exhalation valves are biased to the closed and open positions respectively and the bias is overcome by the cyclic application of gas supply pressure. The system is actuated by two bellows 2, 4, the first of which is smaller than the latter so as to operate at a higher pressure. This bellows 2 is inflated from a gas supply, against a loading spring 14 until it actuates an electrical contact 20 which opens a valve 10 to allow the gas to pass into and inflate bellows 4 which continues until a contact member 24 engages a switch 26 and again closes the valve 10. During this time the inhalation valve 32 is held closed, by an adjustable compression spring 44, and the exhalation valve 34 is held open by a tension spring 66, which holds the diaphragm 58 clear of the seating 56, so that the patient, at 52, exhales freely through a valve 62 or into a breathing bag 64. The closure of valve 10 during this period allows the pressure to be gradually built up in bellows 2 and this is communicated by pipe 68 to the valve 34 where by bearing on diaphragm 58, it ultimately overcomes the bias of spring 66 and closes the valve. Subsequently, also, as the pressure continues to rise, it bears on the diaphragm 42 until it overcomes the spring 44 and opens the inhalation valve, whereupon the bellows 4, under the influence of a weight 18, forces its contents into the patient's lungs. Finally, the completion of the inflation of the bellows 2 again opens the valve 10, whereupon the pressure in the pipes 6, 46, 68 falls to a low value and the system reverts to the exhalation phase. Specification 900,866 is referred to.

Title: Manufacture of colloidal sulphur
IPC: C01B17/10
Filed: 1921-09-23
Abstract: Sulphur is dispersed mechanically in a mixture of a non-solvent and a substantial amount of a solvent in the presence of a dispersator containing a sulpho group, such as sulpho derivatives of fatty acids, naphthenesulphonic acids, sulphonated castor oil acids, thionic acids or purified sulphite-cellulose liquor.  Protective colloids may be added to preserve the solution when made, and it may be concentrated, such as by ultra-filtration or electro-osmosis.  In examples, a solution of sulphur in carbon bisulphide is emulsified in a colloid mill with water and sulphonated castor oil acids, or the water and carbon bisulphide together with a sulphonic acid and gum arabic, are first emulsified in a mill and the sulphur added and the mixture again treated.  To obtain the colloidal sulphur in solid form, a protective colloid such as gelatine or Iceland moss is added, if one is not already present, and the solvent evaporated.  Other solvents mentioned are benzol, phenols, amines, or oils. According to the Provisional Specification any dispersator of an acid nature may be employed.  Specification 155,836 is referred to.
