Title: Improvements in or relating to the manufacture of artificial threads or filaments from cellulose esters or ethers by the dry spinning or evaporative method
IPC: D01F2/30
Filed: 1927-12-23
Abstract: 314,404. British Celaaese, Ltd., Payne, R. W., and Roberts, R. P. Dec. 23, 1927. Cellulose esters and ethers, processes for making filaments from; apparatus for making filaments.-Artificial silks exhibiting a reduced lustre or even a dull matte lustreless appearance, are obtained by the dry-spinning of solutions in volatile solvents of cellulose acetate or other organic acid esters of cellulose or of cellulose ethers, the filaments being extruded into an atmosphere containing one or more organic precipitants for cellulose acetate &c., or the spinning solution containing such a quantity of one or more organic precipitants and the spinning conditions being so chosen that the latter exert a precipitating action on the cellulose acetate &c. during the early stages of filament-formation. Suitable precipitants are-alcohols, such as ethyl alcohol and cyclohexanol; hydrocarbons such as benzene, xylene, petrol and petroleum ether; esters such as butyl propicnate; and ethers such as propyl ether. When the precipitant is added to the evaporative atmosphere it is convenient to introduce it into the cell either in the form of a vapour or as a spray at a point in the path of travel of the filaments at which the latter are still wet with the solvent, that is, within a few inches of the spinning nozzle, and it is convenient to provide a separate inlet for each group of filaments. The degree of delustring depends on the temperature maintained in the cell. When the precipitant is added to the spinning solution, the quantity employed may be 1-40 per cent, preferably 5-30 per cent, of the quantity of volatile solvent; the degree to which delustring takes place depends on the proportion of precipitant added and the temperature of spinning, being generally greater as the proportion of precipitant is higher and the temperature is lower.

Title: Device for the inhalation of medicaments
IPC: A61M15/00
Filed: 1972-08-04
Abstract: 1404338 Administering medicines BEECHAM GROUP Ltd 2 Aug 1973 [4 Aug 1972] 36428/72 Heading A5T A device for the oral inhalation of finely divided solid medicaments comprises a hollow housing and a capsule holder fixed to an elongated vibratable member which is fixed at one end within the housing at a point remote from the capsule holder, the housing having inlet and outlet vents permitting air to flow through the housing, and means causing the member to vibrate, the outlet vents being adapted for application to or insertion into the mouth, and positioned such that the finely divided medicament is carried through the outlet vents at the intake of breath by the user of the device. As shown in Fig. 1, a hollow, generally cylindrical housing 1 has a flat reed 4 mounted on a projection 5 at the end of the housing. A capsule 3, containing finely divided medicament, is held in a holder 2 at the other end of reed 4. In use, the patient inhales at the outlet vents 7, so that air flows in through vents 6 to baffles 8 in the body and baffle 9 on reed 4. The baffles 8, 9 are arranged with a small gap between them, so that turbulence occurs in their vicinity. The reed is vibrated, and powder is shaken out of the capsule, which is pierced for the purpose, before loading or in situ. A constriction 10 is formed near the capsule to provide for low pressure to help disperse the powder. The housing 1 is made in two parts, with screw threads or a snap fastening at X, for placing the capsule in holder 2. Vents 6 may be omitted and air enters by a single vent or opposed vents in the side of the housing, co-operating with the reed or baffles mounted on opposite sides of the reed parallel to the housing walls. Vents 7 may be replaced by a plug drilled with a hole which has a cross-sectional area approximately equal to the area of the annular gap between a side vent and the reed at their greatest separation. In another embodiment, Fig. 6, air enters by tangential vents 406 (see also Fig. 7, not shown), and a vent 406a. A piercing member 421 slides coaxially in housing 401. As the patient inhales through the vent 407, a vortex is formed around holder 402, which rotates orbitally and strikes the inside of housing 401 successive light blows. Air is also drawn through vent 406a, passing partly through passage 417 and through capsule 403, adding to the turbulence. Consequently, powder issues from the capsule in a helical path. Lighter particles are inhaled through the vent 407; heavier particles whirl round in a trough 422 surrounding vent 407 until they are abraded to a size such that they also pass out through vent 407. The vibrating rod may be mounted on a spring-biassed pushbutton, and the capsule impaled on a hollow piercing member of the holder, so that it may be pushed on to a second piercing member by pressing the button. Where the patient is unable to suck sufficiently hard, his efforts may be supplemented by a rubber squeeze bulb.

Title: Improvements in or relating to platen printing machines, more particularly addressing machines
IPC: B41L47/42
Filed: 1929-11-29
Abstract: 343,207. Printing-machines. ADDRESSOGRAPH CO., 901, West Van Buren Street, Chicago, U.S.A. Nov. 29, 1929, No. 36679. Convention date, Feb. 23. [Class 100 (ii).] Addressing and like machines; platen machines.- A platen printing-machine, more particularly an addressing-machine, having a stationary or moving platen arm is provided with a quick-acting or snapping platen head mounted on the arm and adapted to move relatively thereto in the snapping action to give a rapid impression blow. As shown applied to an addressing machine, a platen 16, Fig. 6, is carried by a support 17 pivoted at 18 to an arm 9, which is rocked about a pivot 10 by an oscillatable cam 11 engaging a roller 9<1> on the end of the arm. During the first part of the movement of the cam 11, the roller 91 rides on a steep part thereof so that the platen 16 is moved into the full line position : the roller 91 then rides on an arcuate surface 11<1>, and the arm 9 therefore remains stationary. Through the intermediary of a link 33, bell crank 30, 31, link 29, and arm 28, the cam subsequently rocks an arm 25 about a pivot 27 so that a roller 24 on the end of the arm 25 moves into engagement with an inclined surface 23 on a latch 20, which is pivoted at 21 on the support 17 and is pressed by a spring 34 against an adjustable screw stop 35. The arm 25 therefore rocks the support 17 in an anticlockwise direction into the broken-line position meanwhile tensioning a spring 19, which is released when the roller rides off the surface 23. The rebound of the spring brings the platen 16 smartly down on to the paper 15 laid on an address plate 13 on the printing table 8. The movement of the platen 16 is limited by an arm 36, Fig. 7, loosely mounted on the pivot 18 and engaging, through the intermediary of a cushioning pad, a plate carried by an arm 37 rigid with the support 17. During the impression blow, a roller 42 on the arm 36 engages an inclined surface 41 on a lever 40 pivoted at 40<1> on the arm 9, whereby a spring 43 is tensioned and, immediately after the impression, returns the lever 40, and therefore the arm 36, to normal position, and raises the platen arm 17. On the return movement of the cam 11, the roller 24 rides over the end of the latch 20, which is then returned to normal position by the spring 34. Impression adjustments.-The arm 36 bears against a screw 39, Fig. 7, by adjustment of which the downward movement of the platen 16 may be varied.

Abstract: 1,048,158. Assembling upholstery springs. SPUEHL A.G. Sept. 8, 1964 [Sept. 9, 1963], No. 36696/64. Heading A4M. In a machine for manufacturing spring interiors 1 wire spirals 15 for interlacing upper and lower convolutions of coil springs are fed from a wire spiral production machine C to a spring assembly machine B by a feeding device A comprising a band-like conveyer 16 formed of chains 11 interconnected by transverse holders 13, 14 for wire spirals 15, first driving means, such as a gear 26 and pinion 27, for driving the conveyer 16 through a receiving station in synchronision with the spiral production machine C, second driving cams, such as a free wheel sprocket 17, for driving the conveyer 16 through a spiral delivery station in synchronison with the assembly machine B, and switch means 35, 36 responsive to the slackness of the conveyer 16 and hence the demand of the assembly machine B for switching on and off the spiral production machine C whereby the conveyer 16 also serves to accumulate wire spirals 15 in its feed run 16 1 . The chains 11 of the conveyers 16 are slack and are guided over sprockets 8, 9, 10 mounted on shafts 5, 6, 7 and the interconnecting spiral holders comprise angle irons 13 carrying spaced tubes 14. The drive of the run 16 2  through the delivery station is controlled by the assembly machine B operates through the free wheel sprocket 17 around 90 degrees of which passes a chain 18 spring loaded 19 at ane end and attached 21 its other end to a vertically movable rod 21 mounted on a support 22 carried by a beam 24, the beam 24 being vetically movable by the operator of the assembly machine B and serving to carry tongs for supporting a row of coil springs to be connected together. Compressed air cylinders 32 with pistons 33 carrying pushers 34 serve to eject a pair of spirals 15 from their holders 13, 14 into the automatic feed device of the assembly machine B. Limit switches 35, 36 are actuated when contacted by the conveyer run 163 extending between upper and lower chain sprockets 8, 9 in its extreme positions of slackness. In operation, when the run 16 3  has its minimum slackness due to the higher rate of supply of spirals 15 from the machine C the run 16 3  actuates the switch 36 to switch of the spiral production machine C and stop rotation of the lower sprocket 9 whereby the run 16 3  slackens as the delivery of spiral 15 to the assembly machine B continues until this run operates the other switch 35 to re-start spiral production and hence accumulate spirals in the now slackening lower run 16 1 . Electromagnets 37, 38 serve to operate jaws 40, 41 and 43, 44 to clamp a spiral 15<SP>11</SP> whilst the latter is tempered by the passage of an electric current.
