Title: Parting composition and method of pack-rolling using the same
IPC: F21V37/00
Filed: 1950-06-20
Abstract: Parting compositions for use in the hot pack-rolling of metal slabs and plates (see Group XXII), comprise a homogeneous suspension of inorganic material which is substantially infusible, inert to the metal to be rolled, and non-decomposable below 2400 DEG  F., and which passes a 100 mesh standard A.S.T.M. sieve, in a solution of about 0.04-4 per cent by weight of a cellulose ether or ester in a volatile organic solvent substantially free from chemically combined chlorine and aromatic hydrocarbons, the solvent comprising an ester of a saturated fatty acid containing 1-5 carbon atoms with an aliphatic alcohol containing 1-5 carbon atoms.  The proportion of the inorganic material to the solution is between about 3 and about 1/3 volumes of the former per volume of the latter, said volumes being the volumes of the stated components before mixing together and the volume of the inorganic material being measured after pouring the material into a container without tamping or violent tapping. The cellulosic binder may be an ethyl cellulose, particularly of about 47-50 per cent ethoxy content, a cellulose acetate or a p  cellulose nitrate, the latter being preferred.  The inorganic material may be a refractory metallic oxide such as magnesium, zirconium, aluminium, or titanium oxide, the chromium oxides, such as precipitated chromium sesquioxide, a refractory silicate such as mica or magnesium silicate, chromite or calcined periclase. The solvent may be methyl, ethyl, isopropyl, butyl or amyl acetate, ethyl acetate being preferred.  The solvent may comprise a mixture of esters and may contain a minor proportion of another volatile solvent or solvents such as a lower aliphatic alcohol, e.g. methyl, ethyl or propyl alcohol, or a lower aliphatic ketone such as acetone.  In an example a cellulose nitrate is dissolved in ethyl acetate to provide a concentration of 0.4 per cent by weight.  With this solution is thoroughly mixed an equal volume of chromium sesquioxide passing a 350 A.S.T.M. standard sieve, and the paint-like composition is applied to one face each of stainless steel plates to be pack rolled (see Group XXII).  The composition does not deleteriously affect, as by carbonization, the surfaces of the metal members to which it has been applied, dries quickly and does not disintegrate during the process with exposure of the underlying metal surfaces.

Title: Controlling device for electric drives for knitting machines
IPC: D21H17/35
Filed: 1933-05-31
Abstract: 399,758. Knitting-machines. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. May 31, 1933, No. 15763. Convention date, June 10, 1932. Addition to 386,833. [Class 74 (ii).] The invention described in the parent Specification is modified in that the electrical speed regulator can be connected optionally with a member 2 for adjusting the working speed of the knitting-machine and with a member 3 for controlling the transition to reduced speed for narrowing &c. The arrangement is such that the member which for the time being is nearer to the zero position of the regulator is coupled automatically to it. A gear segment 11 operatively connected at 12 with the brushes of a motor inside the casing 13 is mounted freely on a shaft 10, on which the levers 2, 3 are also freely mounted. Lever 2 is connected to the rod 21 by which the feed is controlled. Lever 3 is controlled by a pattern chain 35. The segment 1 carries a pin 14 on which are pivoted catches 15, 16 which may hook on to pins 25, 36 carried by the levers 2, 3. Stops 28, 37 on the levers 2, 3 respectively engage pins 18, 17 on the catches 16, 15. Thus, when a stud 34 moves the lever 3 to the left through intermediate devices 31, 32, 33 the stop 37 acts on pin 17 and releases pin 25 on lever 2 from the catch 15. At the same time the pin 36 hooks on to catch 16. Thus, lever 3 is connected to while lever 2 is disconnected from segment 1. When the stud 34 passes out of range the action is reversed, lever 2 being connected as lever 3 is disconnected. Movement of the lever 2 to the left is limited by the position of the lever 3 so that the speed set by the lever 3 cannot be exceeded, but the lever 2 may cause a disconnection at any time.

Title: Improvements in and relating to refining agents for the treatment of sugar liquors and the like
IPC: B01J20/20
Filed: 1948-06-12
Abstract: A refining and decolourizing agent particularly for use in the treatment of sugar liquors or solutions is produced by a method including the steps of heating a bauxite of low iron content, i.e. a bauxite containing not more than 3 per cent by weight of iron determined as Fe2O3 after heating to 150 DEG -110 DEG C, for the removal of most of the combined water, impregnating the bauxite with a carbohydrate liquor or solution, carbonizing the carbohydrate absorbed by the bauxite and thereafter activating the carbon formed as a deposit on the bauxite.  In a modification a bauxite having a greater content of iron than the above may be used in which case it is treated for the removal of a major proportion of its iron content prior to its impregnation with the carbohydrate liquor or solution. This latter treatment may also be applied to a bauxite of low iron content.  The bauxite may be first dried, granulated and washed to remove "fines" and heated in a reducing atmosphere to a temperature of between 350 DEG C to 450 DEG C and then after cooling passed as for example, over a magnetic pulley, for the separation from the material of magnetic granules, the non-magnetic granules being then treated by acid and water wash in batch, counter-current or continuous processes for the removal of sugar-soluble iron compounds, and the material being then dried for the subsequent absorption of carbohydrate material, after which it is again dried and carbonized in a reducing atmosphere to leave a carbon-impregnated base material, which is finally heat-treated in a current of steam for the activation of the carbon previously deposited.
