Title: Apparatus for controlling the rate of discharge of materials through an outlet
IPC: G05D7/01
Filed: 1958-05-23
Abstract: 838,262. Material discharge by means of a liquid. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 23, 1958 [June 5, 1957], No. 16656/58. Class 78 (1). Material from column 1 falls through outlet 8 on to plate 10 and is discharged therefrom by means of an upward flow of liquid passing upwards through perforations in the said plate 10, the flow serving to crumble away the heap of material on the plate so that the material falls to be discharged downwards through valve 14. The liquid flows out of the top of chamber 9 to be pumped back again by a pump. Additional reacting fluid is introduced at 6 and rises to be discharged at 5 and the same pump may serve to pump fluid around both hydraulic circuits. Alternatively the perforated plate may be replaced by a rotatable valve.

Patent GB-627910-A (GB)
Title: Treatment of wool
IPC: D06M13/342
Filed: 1947-06-24
Abstract: The tendency to shrink of textile material composed wholly or partly of wool is reduced by first immersing the material in an aqueous liquid containing a buffering substance to maintain the pH of the liquid between 5.5 and 11.0, drying the material, and then immersing it in a solution of anhydrocarboxyglycine in an organic solvent.  The concentration of buffering substance should preferably be just sufficient to ensure that the difference in hydrogen ion concentration before and after the treatment is not greater than one pH unit.  The process may be applied to woollen material which has been scoured in an acidic liquid with a detergent or which has been dyed in an acid bath.  The organic solvent used may be ethyl carbonate.  The treating solution preferably contains about 5 per cent anhydrocarboxyglycine based on the dry weight of the wool.  For obtaining material that has a soft feel, similar to that of untreated wool, as well as high resistance to shrinking, the solution of anhydro-carboxyglycine may contain an addition of a compound of the formula <FORM:0627910/IV (c)/1> where R is a hydrocarbon chain containing at least eight carbon atoms, e.g. octyl, decyl, or cetyl-diketooxazolidine.  For the pre-treatment there may be used as buffering substance borax-phosphate, ammonia-ammonium chloride, or citric acid-phosphate mixtures, or ammonium acetate, sodium bicarbonate, or sodium silicate.  In an example, knitted merino wool fabric is immersed for 30 minutes in an aqueous buffer solution of pH value within the specified limits and is then rinsed in tap water and air-dried to a condition of 17 per cent moisture regain.  The fabric is then suspended in a dilute solution of anhydrocarboxyglycine in ethyl carbonate containing 1 per cent of water.  The treatment is carried out at 50 DEG  C. for two hours.  The wool is then removed from the solution, squeezed, and then scoured in soap and ammonia solution.  Specification 567,501 is referred to.

Abstract: 565,561. Magnetic tests and measurements. PARK, J. R. Dec. 30, 1941, No. 16764. [Class 37] [Also in Group XXII] A cylindrical body of magnetic material surrounded by a layer of non-magnetic material of uniform thickness is manufactured by a method involving the machining of the layer after positioning the metal body for machining under the control of. an electric gauge. The gauge shown in Fig. 3 comprises an E-shaped laminated core 10, which has a primary coil 14 and a secondary coil 15 mounted on its middle leg, the whole being embedded in wax or pitch in a non-magnetic casing 16. The leads to the boils pass out through a tubular handle 18, the primary winding 14 being connected to an A.C. supply 19, Fig. 4, and the secondary coil 15 being connected through a rectifier. 20 to the grid of an amplifier valve 21. The anode of this valve is connected to a micro-ammeter 22. The gauge is shown in Fig. 3 arranged for testing a bearing bush such as is used on aero engines and which comprises a steel tube 24 covered both outside and inside by white metal 25, 26. The bush is set up in a chuck 27 and the gauge is mounted in the tool holder 28 so that the exposed ends of the core 10 lie close to the outer layer 25 of white metal, the magnetic circuit being closed through the steel tube 24. Variations in the air-gap due to eccentricity of the tube 24 on slow rotation of the chuck produce changes in the magnetic field, which are measured by the instrument 22. The bush is then adjusted in the chuck until the tube 24 is truly coaxial and the inner and outer layers 26, 25 of white metal are machined to a uniform thickness.

Abstract: 751,428. Pulleys. NICOL & ANDREW, Ltd. June 10, 1954, No. 17046/54. Class 80(1) [Also in Group XXIII] A device for honing external cylindrical surfaces in situ, e.g. crank pins, comprises an outer ring member 1 in halves held together by bolts 2, the halves being located by dowels 3. Bifurcated stop members 4 projecting inwardly from the ring member 1 engage a hone-supporting frame 5 supporting hone carriers 6 mounted in hone blocks 7, the latter being held to the frame 5 by bolts 9. The frame 5 is in two portions coupled together at their ends by turnbuckle devices each of which consists of a bracket 10 having a trunnion 10A engaging a bearing in the outer ring member 1, a rod 11 screw threaded at opposite ends with right and left hand threads and passing through the bracket 10, a handwheel 12 fastened to the rod 11, turnbuckle elements 13 engaged with the screwthreaded ends of the rod 11, a locking nut 14, a ratchet wheel 15 located between thrust washers 16, and a pawl carrier 17 supporting a pawl 18 urged by a spring 19 into engagement with the ratchet wheel 15. The pawl carrier 17 is coupled by a linkage including a coupling rod 22 and a ball joint connection 20 to a plunger 21 protruding from the periphery of the outer ring member 1. The pawl carrier 17 is urged by a spring 23 to rotate in the direction to cause the plunger 21 to protrude from the periphery of the outer ring member 1. In use, the portions of the outer ring member 1 and of the hone-supporting frame 5 are separated, fitted around the shaft to be ground and re-assembled; a coarse adjustment of the positions of the hones is effected by the handwheel 12. A driving belt is fitted around the outer ring 1 to rotate it. As each plunger 21 comes under the driving belt it is forced inwardly operating the pawl and ratchet mechanism 18, 15 so rotating the rod 11 and causing the portions of the hone-supporting frame 5 to move towards each other. This is repeated until the hones are in contact with the shaft so that the plungers 21 cannot be moved inwardly. As the hones wear, the plungers 21 are moved inwardly to compensate for the wear. For honing work of considerable length in proportion to its diameter, hones wider than the device may be fitted to the carriers, the device being -moved axially along the work.
