Title: Improvements in means for feeding pirns to rotary traversing winding machines
IPC: B65H67/06
Filed: 1952-02-01
Abstract: 741,283. Feeding bobbins to textile spinning &c. machines. HOLT, Ltd., T., and FITZGERALD, J. Feb. 2, 1953 [Feb. 1, 1952], No. 2714/52. Class 120 (3). [Also in Group XXX] In apparatus for successively feeding pirns to rotary traversing winding machines of the travelling-spindle type in correct alignment for placing them on the winding heads, the pirns P are delivered by a conveyor 10 and fall from a shoot 11 on to revolving shafts 13, 14, through the space between which passes the tail of each pirn which is therefore supported by its head resting on the shafts. The rotation in opposite outward directions and the inclination of the shafts prevents the pirns wedging therebetween and they gradually slide down the shafts until the first pirn P<SP>1</SP> of a series is arrested by an arm 28 a recessed portion of which embraces the shaft 13. When the winding head comes into position to receive a pirn, a solenoid 34 is energized and a link 32 rocks a shaft 25 whereupon the arm 28 is swung in the direction of the arrow A so releasing the leading pirn which then slides down the shafts 13, 14, and drops through the opening between the shafts formed by annular grooves 23, 24, into position on the winding head: at the same time another arm 29 swings inwardly to embrace the shaft 14 and so arrest the second pirn P<SP>11</SP>. The solenoid is de-energized so allowing the arms 28, 29 to return to their initial position, whereupon the second pirn moves into the space between the arms 28, 29. The shafts 13, 14 are displaceable to enable adjustment for various sizes of pirns.

Title: Toning process particularly for toning the red color component image for multi-colorphotography
IPC: G03C5/46
Filed: 1933-01-31
Abstract: 402,619. Photographic processes. JASMATZI, A., 2, Neuer Markt, Vienna. Jan. 31, 1933, Nos. 3043 and 3044. Convention dates, Feb. 2, 1932 and Jan. 21, 1933. [Class 98 (ii).] Toning; colour photography.-A red-toned print, more particularly the red component of a colour photograph, is produced by substituting, for the silver of an image produced in an ordinary silver halide emulsion layer, nickel dimethylglyoxime or a homologue thereof. One method, employing a nickel salt which reacts with dimethylglyoxime &c., consists in first converting the silver into a lead salt by treatment in a bath of lead nitrate and potassium ferricyanide ; then converting the lead salt into a nickel salt by treatment with nickel sulphate ; and finally toning the image red by treatment with dimethylglyoxime &c. Another method, employing a nickel salt which does not react with dimethylglyoxime &c., consists in toning the silver image directly with a bath containing a complex nickel salt such as potassium nickel cyanide, dimethylglyoxime, and ammonia ; but the action is slow, and quicker results are obtained by first converting the silver of the image into silver halide or silver cyanide, or by adding to the toning bath a salt which will effect this conversion, potassium ferricyanide being specially mentioned. A modified tone for the two-colour process may be produced by bleaching the image in a bath of lead nitrate and potassium ferricyanide, toning it red by treatment with potassium nickel cyanide and dimethylglyoxime, and then changing the tone to orange by treatment with potassium bichromate solution. A three-colour picture may be produced by printing the three components on silver halide emulsion layers coated on a strippable base of pergamyn or other diaphanous paper. The blue component is first bleached with a bath of lead nitrate and potassium ferricyanide and then toned yellow with potassium bichromate; the red component is toned blue with a bath of potassium ferricyanide and a ferric salt and the green component is toned red by one of the methods described above. The toned images are transferred in superimposition on to a final support as of baryta paper. The colours may be modified before transfer, if examination of the prints in loose superimposition shows this to be desirable, as by weakening the yellow or blue image in known manner, or by weakening the red image by bathing it in a weak, preferably organic acid other than acetic acid.

Title: Improvements in or relating to apparatus for producing mole drains
IPC: E02F5/10
Filed: 1957-01-29
Abstract: 822,315. Drainage. WOOD, E. April 22, 1958 [Jan. 29, 1957], No. 3064/57. Class 33. [Also in Group X] In a method of strengthening a mole drain, the drain is partially or completely lined with cement which is applied to the walls of the drain by ejecting it from the expander of a mole drain plough in the form of a powder as the drain is being formed. A spray of water is also ejected from the expander to dampen the cement. The floor of the drain may be left unlined and the strengthening material pressed against the earth walls of the drain by a former. The cement may include a quick set additive. A suitable cement is a mixture of half by weight of high aluminous cement, the balance being portland cement, with or without the additive. A quantity of organic matter may be mixed with the cement which will rot away when embedded in the earth, and thus leave a large number of small holes through the lining. Apparatus for carrying out the method comprises a mole-drain plough having apparatus for ejecting cement in the form of a powder from the expander 74. From a hopper 58 to the expander 74 an auger 92 in a feed-box 88 delivers and meters cement blown by an air compressor 62 through a pipe 86, housed in a recess 67 in the rear of the plough blade 66, and through shaped outlet 84 between the expander 74 and a conical member 80 formed on a former 78 which presses the dampened cement against the earth walls. A pipe 94, in which is connected the pump 64, also in the recess 67, leads from a water tank 56 through the expander 74 into the former 78, and through a slot in the pipe wall water escapes into the cone 80 and then through holes 98 in radial jets, not required, however, in very wet ground. The plough preferably incorporates an automatic depth control system for the bar 70. According to the Provisional Specification, the air compressor may be driven from the power-take-off shaft of the tractor drawing the plough or by a separate engine, whereas the flow of cement and / or water may be controlled by valves on the hopper and tank pipes whilst the plough is in the earth, and may be arranged so that the lining is thicker at the bottom than the top of the drain.
