Title: Web-stencilling method
IPC: B41F15/08
Filed: 1953-07-17
Abstract: 738,349. Stencilling. STOFFEL, M. July 17, 1953 [July 21, 1952], No. 19943/53. Class 100(2). In a method of printing on a web of cloth, paper, &c. by means of stencils, the web is bonded to an endless conveyer which is fed intermittently in steps each equal to the length or section printed by each stencil multiplied by twice the number of stencils in use, to carry the web past the stencils and their coacting tables and through a drying chamber; stencilling takes place during the periods when the conveyer is stationary and the arrangement is such that any particular section is printed once only during a complete passage of the conveyer and a section adjacent thereto only in another passage. The web of cloth, paper or plastic to be stencilled is bonded with an easily-removable binder to an endless conveyer 12 passing between three stationary stencils 7 and printing tables 8, and through a drying-chamber C including an airdehumidifying unit 14. The conveyer is driven by rollers 9, 10, 16 and by toothed conveyers 6, all the parts being driven by an electric motor D. The web is passed intermittently through the printing assembly B in steps equal to six pattern repeat lengths, i.e. twice the number of repeat lengths as stencils used. In the initial position of the web the stencils are positioned above the 1st, 3rd and 5th repeats. During the first passage of the web, only the first stencil is used, and prints on the 1st repeat position only. During the second passage, the first stencil prints on the 2nd position. During the next two passages, the first two stencils are used, and during the next two, all three are used. During the seventh and eighth passages, the first stencil is omitted, and during the last two passages only the third stencil is used, after which each position will have been printed on once by each stencil. However, additional stencils may be used by replacing each stencil which has completed its work. Thus, after the sixth passage, the first stencil can be replaced by a fourth, and so on. For example, if twelve stencils are used, three at a time, there will be required twenty-eight passages. If only one stencil is used, only two passages are required. Specification 510,788 is referred to.

Title: An improved machine for printing upon letters and like articles
IPC: B41K3/62
Filed: 1932-07-19
Abstract: 404,673. Printing-machines. JONES, G. V.WYNNE-, and UNIVERSAL POSTAL FRANKERS, Ltd., Victory House, Regent Street, London. June 19, 1932, No. 20449. [Class 100 (ii).] Stamp-cancelling and franking machines hand-stamps.-A portable machine for printing cancellation and dating impressions or postal franks on letters or other mail matter is provided with a reciprocable printing-member depressed by electrical mechanism which is set in operation by manual movement of the machine as a whole. The printing-member 24 is carried by a bridge member 8 connected to the core 5 of a solenoid and guided in slots 9 in the side frames of the machine. The member is normally held in raised position by a spring 40 enclosed in a housing 4 to which an insulated handle 7 is secured. The lower end of the frame is provided with rollers 12, 13, and with a plate 15 pivoted at its rear end to the frame and held in depressed position by a spring. A lever 17 is pivoted to the rear end of the plate and is formed at its upper end as a hook 18 adapted to engage a lever 20, the free end of which engages the upper side of the bridge 8. The bridge carries an insulating member 35 to which is pivoted a contact 31 connected by a spring strip 34 to a plate 36 connected to one pole of a source of current. The other pole is connected to a plate 32 with which the contact 31 engages during descent. In use, the machine is applied to the article to be stamped, and is tilted forwardly until stopped by the engagement of stops 43 on the frame with the plate 15. This causes a slight downward movement of the bridge and printing-member through the parts 17, 20, the movement being sufficient to bring the contact 31 and the plate 32 into engagement in order to energise the solenoid coils and depress the member 24. An inking-pad 27 normally in engagement with the printing-member, is supported by arms 28 pivoted to the frame, and links 30 pivoted to the bridge, so that during downward movement of the member 24 it is swung out of the way. The member 24 passes to printing position through an aperture in the plate 15. The bridge 8 carries a cam 25 engaging a surface on the lever 17 so as to disconnect the hook 18 from the lever 20 during downward movement. The contact 31 passes out of engagement with the plate 32 before the member 24 reaches printing-position so that printing is effected under the momentum of the stamp. A second impression cannot be obtained until the parts have been returned to normal positions which is effected by the various springs. On the return movement, an insulated strip on top of the contact 31 engages the plate 32 due to the pivotal mounting of the contact, so that the solenoid coils are not energised. A counter 44 or, if a value-printing frank is employed, a meter is connected to the rear end of the plate 15.

Title: Improvements in or relating to the pulping of wood chips
IPC: D21C3/06
Filed: 1954-07-13
Abstract: In a semi-chemical pulping process, wood chips ar cooked up to 155 DEG  C. at a pH of 3-5 with a solution of sodium, potassium or ammonium bisulphite having no free sulphur dioxide, and then mechanically refining to separate the fibres.  By "free sulphur dioxide" is meant sulphur dioxide other than that present as bisulphite.  In an example, a digester was charged with 1 part by weight of spruce chips and 5 parts of a solution of sodium metabisulphite to give a total sulphur dioxide content of 2.5 per cent.  The temperature was raised to 110 DEG  C. during 2 hours, to 155 DEG  C. during 2 1/2 hours and maintained at 155 DEG  C. for a further 1 1/2 hours.  The initial pH value was 4.7 and the final pH, 3.5.  The yield was 74 per cent.  The cork was blown, the softened chips washed and passed through a disc refiner. Alternatively, the cooking liquor could be prepared from a solution of soda ash and sulphur dioxide gas.
