Title: Method and Apparatus for Wrapping Block-Like Articles.
Inventor: WAHLE GUENTER
IPC: B65B11/32
Filed: 1966-07-08
Abstract: 1,196,734. Packaging-machines. HAUNIWERKE KORBER & CO. K.G. 20 June, 1967 [8 July, 1966; 21 July, 1966], Nos. 30804/66 and 32851/66. Heading B8C. A method of wrapping articles e.g. block-shaped packets, comprises placing a wrapper blank across the mouth of a pocket in a continuously rotating turret, inserting an article sideways into the pocket so that tucks are formed and the blank is folded to U-shape about it, folding the side portions of the U to form a tube and moving the article lengthwise to sealing means for the tube seam, then moving the article radially out of the turret while folding and sealing the end closure flaps. The articles enter radially adjacent one side face of the turret 4 and are transferred axially during wrapping towards the other side face to a guideway 62, 63 associated with each pocket and extending radially of the turret, Fig. 2. Blanks 2 are cut from a web by a rotary knife co-operating with a drum against which the web is held by suction, Fig. 1 (not shown), for transfer on to plates 31, Fig. 3, forming part of the turret where each is held by suction holes 32 over the opening of a pocket 4. Each article is fed by a conveyer 14 on to a plate 15 and is lifted from the latter by arms 17 associated with the trailing side of each pocket. It is pressed with a blank into a pocket 4 by stationary guides 18 and spokes 20 of a wheel 19. During entry, tucks 140 are folded at the leading end by members 33, 34 and then a jaw 45 folds up the lower flaps and a jaw 44 folds down the upper one and remains in position so that the seam so formed is held for sealing. The partially wrapped article is moved axially into alignment with the respective guideway 62, 63 by axial movement of the enclosing pocket formed by members 29, 30, 33, 34. The folder jaws 44, 45 extend axially to the guideway. A heated reciprocating bar 99 seals the seam. The remaining tucks and upper and lower end flaps formed by the tucks are folded by ploughs 64, 65, 66 respectively and sealed by reciprocating heaters 69 as a pusher 90 moves the package radially outwards. It comes to rest between the presser plates 70 that hold the end closures in place until the package is urged by a following package against a stop 134 formed on a cam device 133. The articles are deposited on a fixed plate 135 and pushed along by the members 133, one at a time or, if only alternate pockets have associated cams, in pairs, on to a conveyer (136) Fig. 1 (not shown). Alternatively, single deposited packages may be conducted by a shoot to a lower conveyer which removes them in pairs. Safety means are provided so that when the turret is stopped the heaters are lifted clear of the packages. Articles may be fed into the loading position axially of the turret, Fig. 5 (not shown).

Title: Improvements in protection apparatus for hydraulic presses
IPC: F16P3/04
Filed: 1938-11-15
Abstract: 521,308. Machinery guards; hydraulic presses. TAYLOR, A. W., TAYLOR, A. H., and SADLER, P. V., [trading as TAYLOR & CO., A.W.]. Nov. 15, 1938, No. 33131. [Class 80 (iv)] [Also in Group XXIX] A hydraulic press is provided with electromechanical, pneumatic, or hydraulic means for locking a guard in closed position except when the operating lever of the control valve is in the exhaust position, and for locking the lever in the exhaust position when the guard is open. Each of one or more sliding lattice gates A<1> A<2>, Fig. 1, carries beaks B, Fig. 5, which enter locks C when the gate is closed, and move contacts C', so as to close the circuit of an electromagnet E. A spring-pressed plunger e, Fig. 3, which occupies a recess d<1> in the shaft of the control lever D', so as to lock the lever in exhaust position when the gate is open, is thereby withdrawn, and the press can be operated. Each gate lock comprises a vertical plunger c<1>, which falls by gravity to lock the gate, by engaging the beak B, and can be raised by an electromagnet c. The circuit of the magnets c is closed, when the plunger e advances to lock the control lever, by a bar e<2> on the plunger, which bridges contacts e<3>, e'. The parts are thus locked in the event of failure of the electric supply. In the pneumatic form, the magnet E is replaced by a pneumatic cylinder, the admission of air to which is controlled by a valve, which is opened by the beaks B when the gate is closed. The beaks are locked by spring plungers which are withdrawn by flexible diaphragms actuated by pressure supplied through a second valve, which is opened by the locking of the control lever. In the case of a down-stroke press the fall of the press-table in the event of failure of the hydraulic supply to the press is prevented by a pivoted locking-bar F, Figs. 7 and 8, which is supported by a spring f<3>, and is moved into the path of the press - table F<1> when the gate is opened.
Patent GB-466216-A (GB)
Title: Improvements in the manufacture of barium sulphate
IPC: C09C1/02
Filed: 1935-12-28
Abstract: Barium sulphate is prepared by reaction between an alkaline barium compound, such as the sulphide or hydrate, or the carbonate, including witherite, in finely divided form, and sulphuric acid, a pH value of 0,5--3 being maintained during the reaction.  This pH range is obtained by the presence in the reaction mixture of an acid or acids capable of giving a barium salt or salts soluble within the pH range.  Acids specified are hydro-chloric, phosphoric and hydrofluoric acids.  These may be added wholly to the barium compound, or in part so and in part to the sulphuric acid. Alternatively, the reactants may be passed into an aqueous solution of the acid(s), or the reactants and the acid(s) passed in separate streams into the reaction vessel.  They may also be formed in situ by the addition of the appropriate barium salts.  No free sulphuric acid or soluble sulphates should be present during the precipitation.  The barium compound and sulphuric acid may be added to the reaction vessel simultaneously and separately, or alternatively in such manner that a pH value within the limits 0,5 and 3 is always maintained. Water-soluble barium compounds used are advantageously previously crystallized. The crystals may be used directly.  Barium carbonate is added to the reaction vessel as a suspension.  Examples relate to the use of barium sulphide solution at 40 and 60 DEG  C., to the use of sulphuric acid of varying strengths, including oleum, to the maintenance of the pH value using indicators or an automatic pH recorder, and to thorough stirring of the reaction mixture.  The product is washed by decantation, or is filtered and washed. Hydrogen sulphide evolved is removed and can be converted to sulphuric acid or sulphur.  The barium sulphate is suitable for filling and coating paper, for medicinal purposes in X-radiology, for incorporation with titanium or other pigments for use in paints, enamels, rubber, &c. For example, titanium sulphate may be hydrolyzed on the product.

Title: Improvements in or relating to knitting machines of the links-and-links type
IPC: D04B9/10
Filed: 1946-11-13
Abstract: 643,457. Knitting-machines. JACQUARD KNITTING MACHINE CO., Inc. Nov. 13, 1946, No. 33701. Convention date, Nov. 13, 1945. [Class 74 (ii)] A needle jack or slider for engaging a double-ended needle of a links-and-links machine is cut away at its tail end to allow the slider to be rocked out of engagement with its needle when the tail is engaged by a cam during transference of a needle from one needle bed to the other. As described, the invention is applied to a circular machine having two coaxial cylinders and in which the sliders are formed with a needle engaging portion 9, an outer edge 15, a butt 11, for engagement with the cam raceways, and a tail 12 having a cut-away portion 13 and a butt 14. The slider camway of the machine comprises gate cams 37, 38 for directing the sliders so that the needles traverse an operative or inoperative path and gate cams 42, 53 which direct the sliders to permit the needles to be transferred to .the other needle bed or to continue the normal knitting operation. Transference of the needles from the lower to the upper needle bed is effected by directing the sliders of the lower cylinder along the path 40 so that the needles are engaged by the upper sliders travelling along the path 44. The upper camway is recessed at 45 to allow the sliders to rock as they are engaged by the advancing needles. The tail butt 14 of the lower sliders is then rocked by a cam 16 to disengage the lower sliders from the needles, the cut-away portion 13 of the sliders allowing the sliders to rock, and the action of the camway then proceeds to withdraw both upper and lower sliders with the effect that the needles are transferred to the upper cylinder. The camway is recessed at 48 to permit the rocking of the sliders in the lower cylinder. Similarly, when the needles are to be transferred from the upper to the lower bed the gate cam 53 is operated to direct the upper sliders along camway 55 so that their tails engage cam 52 whilst the lower sliders pass along the path 39. Corresponding recesses 46 and 51 in the camways are provided to permit the appropriate rocking of the sliders. Alternatively, instead of providing the recesses 46 and 51 in the camways, the sliders may be recessed to permit them to be rocked.
