IPC: F01D19/00
Filed: 1974-06-03
Abstract: 1410320 Servo-systems WESTINGHOUSE ELECTRIC CORP 3 June 1974 [12 June 1973] 24455/74 Heading G3P A control arrangement for a steam turbine system having first and second stages 21', 45', each of which is provided with a flow and by-pass valve 19', 27', and 49', 59', and input means 61' providing a signal indicative of the power requirements of the system, characterized in that each stage includes a means 67', 69', for detecting the power output of the respective stages, and means 63', 65', for comparing these outputs with the input signal so as to supply error signals to control main flow valves 19', 49', and independent means 93', 101', for adjusting by-pass valves 27', 59', in response to adjustment of the flow valves 19', 49', so as to maintain a desired minimum flow through by-pass lines 25', 57', and the turbine stages, and correlating means 75', 77', which modify the input signal so as to produce equivalent variations in the flow through the turbine stages. In operation, an input signal 61' is conveyed to means 63', 65', of the two stages where the signal is compared with power signals 67', 69', received from the turbine stages, the error signal being used to adjust the main valves 19', 49', through regulators 71', 73'. A pair of function generators 75', 77', modify the input signal to produce  equivalent variations of flow through the two stages, and a generator 79' connected into the system can vary the effective input signal until the power output of the system equals the power requirements. The by-pass valves 27', 59', are adjusted inversely to the adjustment of valves 19', 49', when the latter are adjusted so as to maintain the desired flow through the by-pass lines, and turbine stages by pressure transducers 93', 101', the signals from which are compared at 95', 103', with reference signals 97', 105', the error signals passing through regulators 99', 107'. The by-pass valves 27', 59', are initially adjusted more quickly upon adjustment of the main valves 19', 49', by signals passing from regulators 71', 73', through equalizing means 111, 115, to comparators 109, 113. It is stated that the invention relates to the control of a steam turbine having HP, IP & LP stages 21', 45', 47' wherein the system is interfaced with a high temperature gas cooled reactor having a coolant pump driven by a steam turbine stage 37'. It is necessary to operate stage 37' to circulate helium coolant even when power is not being extracted from the turbine system.

Abstract: 356,436. Reservoir pens. WAGNER, G., [Firm of], 292, Podbielskistrasse, Hanover, Germany. Aug. 16, 1930, No. 24577. Convention date, Aug. 19, 1929. [Class 146 (iii).] In a reservoir pen of the type in which capillary ink-feed channels F are formed along the bottom of the air duct E in the feed-bar B, the air duct tapers gradually towards the reservoir so as to provide increasing resistance to the inflow of the air and so prevent flooding. The air duct is widest opposite the air opening D in the nib and tapers to a position adjacent the end of the nib shank where it is suddenly enlarged to prevent reduction of the duct to such an extent as to tend to cause choking. In use, ink from the reservoir fills the duct E to the positions J, L when the bubble G breaks away, and the resistance of the ink at J prevents a sudden inrush of air with the resultant overflow of ink and closing of the opening D.

[Also in Divisions H1 and H2] Contacts 7 and 8, intended for mounting at an end of a nuclear fuel element and to co-operate with a similar pair of contacts, are mounted on bi-metallic strip diaphragms 4, 9, and at low temperature do not protrude beyond the wall of support 3. With increasing temperature strip 4 reverses its curvature and strip 9 increases its curvature, pressing the contacts outwards and against those with which they co-operate. Preferably the bi-metallic elements are so designed that when the contacts abut the thrust exerted by element 4 is double that exerted by element 9. During cooling periods the contacts retract, opening the circuit. Contact arrangements of this sort are stated to be particularly useful in a horizontal fuel element channel in a nuclear reactor, where the weight of the elements is not available to clamp electrical contacts. If desired, the bi-metallic diaphragms may be mounted separately in the housing so that the thrusts on the contacts are independent.

Abstract: 259,612. Warburg, O. Oct. 9, 1925, [Convention date]. Materials and compositions for making beverages.-In the artificial preparation of natural mineral waters, predetermined quantities, of substances which react) to give the requisite free carbonic acid and other substances required are dissolved in water. Predetermined quantities are also added of missing or insufficiently present components, having regard to the change of constitution in the reaction. In the example described, Karlsbad " M³hlbrunnen " water, which contains chiefly sodium sulphate, sodium bicarbonate, and free carbonic acid, is prepared by dissolving in water, the temperature of which has preferably been regulated to that of the natural spring, sodium bicarbonate and sodium bisulphate which react to give sodium sulphate and the necessary amount of free carbonic acid. Three equivalents of bicarbonate are employed to give the concentration of bicarbonate required in the finished product. As the natural water contains less free carbonic acid relatively than sodium sulphate, the necessary quantity of neutral sodium sulphate is added. Other neutral constituents of the natural water may also be added. In a similar manner, other natural mineral wafers may be produced. The Specification as open to inspection under Sect. 91 (3) (a) comprises also compressing the bicarbonate and bisulphate into separate tablets before use, the other constituents being distributed between the two tablets. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 18700/91.
