Patent GB-484736-A (GB)
Title: Improvements in the purification of soya bean oil
IPC: C11B3/00
Filed: 1936-12-24
Abstract: Soya bean oil is purified by freezing it from substances causing undue frothing, e.g. phospholipoids, and then submitting it to high vacuum short path distillation, preferably under conditions of molecular distillation.  The phospholipoids are removed by adding a substance in which the glycerides are soluble and the phospolipoids are insoluble.  An electrolyte such as magnesium chloride or cadmium chloride may be added as well as the glyceride solvent.  In the example, one gallon of soya bean oil is added to twice the volume of acetone with constant stirring.  The precipitated phospholipoids are removed by filtering or centrifuge, and are used for the preparation of lecithin.  An addition of 20 cc. of a saturated alcoholic solution of magnesium chloride makes the precipitation of the phospholipoids more complete.  The acetone is distilled off in a recovery still and the lecithin-free oil is then transferred to a molecular still and subjected to distillation at a pressure of between 1 and 20 microns. Edible odourless oil is then obtained.

Abstract: 1,065,427. Automatic control systems for aluminium reduction pots. REYNOLDS METALS CO. Aug.28, 1964 [Aug.30, 1963], No.35452/64. Heading G3R. Apparatus for controlling the working voltage Vw of a plurality of aluminium reduction pots 1, 2, N each having a relatively movable anode 12 and cathode 13 comprises, for each pot, a variable resistance 26 which is connected across the anode and cathode, and which has a tap 31 adjusted to produce a voltage VR proportional to the voltage Vw; a scanning switch 32 which sequentially connects each signal VR to a controller 33 including a standard voltage source Vs which is compared with VR of each pot 1 to N; and reversible air motors 17 connected to solenoid-operated valves 22, 23 which are controlled in response to the output from the controller 33 so that the spacing between the anode and cathode of each pot is varied in response to variations between the voltages VR and Vs in such a manner as to tend to balance each of said voltages. Since the different variable resistances 26 are adjusted for each pot, any difference in Vw for optimum conditions in each pot is compensated for and a single standard voltage Vs can be used for comparison. The apparatus may include means for preventing the control action until the voltage VR varies outside a determined control range and means for disconnecting the control system when the line current is not within a predetermined range. Suitable switching, controller and adjusting circuits, together with associated timing circuits, are described with reference to Figs.4, 5, 6 and 7 (not shown).

Abstract: 931,686. Mounting cop sleeves. J. J. KEYSER. Oct. 3, 1961 [Oct. 12, 1960], No. 35685/61. Class 120 (2). A cop sleeve 11 is mounted by holding means in a tubular member 1 or 101 which is rotatably mounted in the walls 2<SP>1</SP>, 2<SP>11</SP> of a spindle rail and driven either by a band 17 or a belt 15, the holding means taking the form of resilient rings 10, 13, 14. The rings 13, 14 engage either grooves 12 in member 1 or corrugations in member 101 while the resilient ring 10 lies between a flange 6 on the top of the tubular member and a bushing 9 which is downwardly urged by a spring 7 engaging between a ring 8 in the bushing and the flange 6 so as to flatten ring 10 to grip the cop tube as shown in Fig. lb. The rings may be solid, hollow, hexagonal as seen from above, or in the form of a wire spiral bent into a circle; if the ring is hollow it may, by means of a valve, be filled with air to a predetermined pressure to give the required holding and damping properties. In a further form the support for the bottom of the cop sleeve is a permanent magnet held between adjacent rings in the tubular member and the cop sleeve is of magnetizable material or has, at its lower end, an insert of magnetizable material so as to be axially located by the magnet (see Figs. 3a, 3b, not shown). In Fig. 5 the holding means for the cop sleeves comprises segments 37 pressed into contact with the sleeve 35 by the downwardly urged bushing 29, while a resilient sleeve 26 supports and locates the lower end of the cop sleeve 34. In this embodiment successive sleeves are introduced through sleeve 26 from below and when sleeve 35 is doffed sleeve 34 is pushed into its position by a further inserted sleeve 39 which then takes up the position which was occupied by sleeve 34. As shown in Fig. 6a, when cop sleeves 41 having rings 42 on the lower end thereof are used, a resilient sleeve 43 having groove engaging parts 44 and 45 is nserted between the tubular member and the cop sleeve to mount the latter. In the form shown in Fig. 7b a supporting sleeve 58 is located in the tube at 53 by an elastic ring 54 and has mounted thereon an inner cop sleeve 59 initially located by ring 54<SP>1</SP> in groove 58 and an outer cop sleeve 60 located by ring 10. The cop is initially wound on sleeve 60 and when this is filled, sleeve 59 is raised so that notch 55 is now located by ring 54<SP>11</SP> and winding is continued on the exposed portion of the inner sleeve 59. The tubular members may be driven by belts or bands or by worm transmission or by designing the tubular member as the hollow drive shaft of an electric motor.

Title: Sheet delivery device in a printing press
IPC: B65H29/04
Filed: 1975-08-29
Abstract: 1493291 Stacking sheets ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER AG 29 Aug 1975 [29 Aug 1974] 35785/75 Heading B8R To facilitate removal of a completed stack 2 from the delivery location of a printing press, an oncoming sheet in sheet path 4 is clamped between a support 6 and finger 8 and serves to support further sheets until the stack 2 has been removed and an auxiliary stacking board has been correctly located. The board, when first introduced into the delivery location trips an element which actuates a pneumatic cylinder 12 or an electromagnetic motor. This pushes a rod 11 which moves the support 6 and finger 8 rightwards to the illustrated position. As sheet delivery grippers, driven by a horizontally oscillating member 22, continue to operate, a cam 21 mounted on member 22 comes into contact with a roller 19, Fig. 2, associated with linkage 18, 23, 25, 27 slidably mounted on a bar 16. The linkage is thus caused to slide rightwards, since link 18 is pivoted to the bar 16, causing link 27 to trip a latch 30 and release a slide 13 thereby allowing finger 8 to descend under the influence of a spring 31 and clamp the oncoming sheet. The bar 16 is articulated to the slide 13 and is slidable in a pivotable member 17. Thus descent of the slide tilts the bar 16 to position A and moves the roller 19 out of the path of the cam 21. Oncoming sheets are stacked on the clamped sheet until the auxiliary board is correctly located and the stack 2 removed. Then rod 11 is retracted by cylinder 12 thereby moving the support and finger assembly 6, 8 leftwards and causing rollers 14 on slide 13 to ride up cam surfaces 32, 33. This raises the slide and finger 8 to a position in which they are re-latched at 30, releasing the sheets on to the auxiliary board and tilting bar 16 to its position B. Jogging means 3 remove sheets from the opened support and finger assembly 6, 8.
