Heating parts: casings; leakage-preventing devices; condensation water, draining.-In a turbine of the type having a diaphragm carrying stator 3, separate from the casing stator and exposed on the exterior as well as the interior to the motive fluid, the stator is supported at one end by a diaphragm or spider 4<a> secured near its inner periphery to a part of the turbine such as the gland or bearing housing 6 which is unaffected by irregular expansion of the turbine casing, and at its outer periphery housed in a grooves 8 in the casing or in some part connected therewith, sufficient radial clearance being provided to permit relative expansion of the diaphragm and casing. The other end of the stator is carried by a spider 19 recessed into the other gland housing with a clearance 20 for axial expansion. A flange 25 on the stator 3 engages with a groove 26 in the casing to take up the thrust and to prevent leakage of steam which is admitted to the outside of the stator bv holes 21 one of which at least is in the lowermost part of the stator to act as a drain. The stator 3 and diaphragm 4<a> are connected by interfitting annular rims 22. 23 with a clearance 24 to permit expansion. Fig. 3 shows a modification wherein the thrust is transferred to the diaphragm 4a by a flange 27 on the stator rim 22 which fits in a groove, on the diaphragm rim 23; in this case a steam-pressed piston ring 29 in a groove 30 on the stator prevents leakage of steam. When the steam inlet, chamber 9 is divided into compartments the diaphragm 4a may be held up against ribs on the end cover by bolts 18 which are sufficiently long to permit radial expansion of the diaphragm. Rotational movement is prevented by lugs on the casing engaging flanges on the stator.

Title: Improvements in or relating to process for the preparation of starch phosphates
Inventor: NEUKOM HANS
IPC: C08B31/06
Filed: 1955-08-15
Abstract: An alkali metal starch phosphate is prepared by commingling starch with an aqueous solution containing at least one orthophosphate salt of an alkali metal, e.g. lithium, sodium or potassium, and having a pH between 3.0 and 7.5, contacting said starch and said solution in a proportion and at a phosphate concentration and for a time sufficient to incorporate said orthophosphate in said starch in an amount equivalent to at least 1.0 per cent by weight of phosphorus, removing unabsorbed liquid from the treated starch, and heating the treated starch at a temperature between 120 DEG  and 175 DEG  C. for a period of 1 to 15 hours.  The heating is carried out either at atmospheric pressure or under vacuum.  The aqueous solution of orthophosphate salt is prepared by dissolving an alkali metal phosphate salt such as monosodium phosphate or disodium phosphate, or a combination of monosodium and disodium phosphate, in water in such a proportion that the resulting solution has the desired pH.  The phosphate salt may also be formed in situ either by dissolving a basic phosphate, such as trisodium phosphate, in water and adjusting the pH with phosphoric acid, or by neutralizing an aqueous solution of an acidic phosphate salt or phosphoric acid with an alkali metal hydroxide.  In a preferred procedure, 3 to 4 parts of starch are treated with 5 to 8 parts of solution containing between 2.5 and 30 per cent concentration of phosphate and having a pH between 3.0 and 7.5, preferably between 5.5 and 7.5, the resulting slurry is agitated for at least 5 minutes, the starch granules are separated from the solution, e.g. by filtration, and excess surface moisture is removed, for example by drying in air or by heating at a temperature below the gelatinization point of starch.  The resulting granules, containing 8 to 15 per cent moisture, are then heated at 120 DEG  to 170 DEG  C. for 1 to 15 hours.  Generally 4 hours is sufficient at a temperature between 130 DEG  and 155 DEG  C.  The process is applicable to root starches, such as potato starch, or cereal starches, such as corn starch, and wheat starch.  Starch phosphate films may be cast from cooled solutions of the phosphates.  The products are also useful as sizing agents in the surface finishing of paper, as beater additive in paper making, as a water loss inhibitor in oil well drilling muds, as a core binder in foundry cores and as a thickening agent in food products.  Detailed examples are given. Specifications 812,340 and 812,363 are referred to.ALSO:Alkali metal starch phosphate, useful as a thickening agent in food products, such as soups, ice cream, puddings, mayonnaise, salad dressings and pie fillings, is prepared by mixing starch with an aqueous solution of at least one orthophosphate salt of an alkali metal, e.g. lithium, sodium or potassium, at pH 3-75, removing unabsorbed liquid from the starch and heating it at 120-175 DEG  C. for 1 to 15 hours.

IPC: G05D23/275
Filed: 1957-07-24
Abstract: 832,401. Automatic temperature control systems. KINGSTON CONTROL SYSTEMS Ltd. July 22, 1958 [July 24, 1957], No. 23512/57. Class 38 (4). In an electric system for automatically controlling a variable, selective energization of three relays is arranged to increase the control effect in four steps. In the arrangement shown, contactor coils K 1 -K 4  each control the connection of a separate space heating element (not shown). Thermostat contacts 1-5 are in the condition shown when the temperature has a desired value. A relay DR is then energized to connect coils K 3 , K 4  so that two heating elements are operating. If the temperature rises contacts 2, 3 close to energize a relay SB to disconnect coil K 3  so that only one heating element is operating. If the temperature rises still further, contacts 3, 5 close to energize relay SJ to disconnect coil K 4  so that none of the heating elements is operating. If, however, temperature falls below the desired value, contacts 1, 3 close to energize relay SA to connect coil K 2  so that three heating elements are operating. If the temperature falls still further contacts 3, 4 close to energize relay SJ to connect coil K 1  so that all four heating elements are operating. Resistance-capacity networks associated with the relays ensure intervals between their operation but if this is not required relay DR may be dispensed with. Coils K 1 -K 4  may be replaced by the heating elements themselves.
