Patent GB-1007109-A (GB)
Title: Agglomerated sugar mixtures and process for preparing same
IPC: A23L27/30
Filed: 1961-09-06
Abstract: 1,007,109. Sugar preparations. PILLSBURY CO. Sept. 6, 1961 [Sept. 6, 1960], No. 26050/61. Drawings to Specification. Heading A2B. A free-flowing, non-caking, readily dispersible or dissoluble, porous, agglomerated premix sugar product includes as essential ingredients at least two substances of which one is a sugar and the other is a "conditioning agent". It consists of clusters of pulverulent particles bonded together with voids and interstices between them. The sugar comprises the greater part of the product and the primary agent for holding the particles together in agglomerated form. The "conditioning agent" is a substance that dissolves in water to form a true or a colloidal solution, and inhibits the crystallization of sugar or increases the viscosity of aqueous dispersions, or both. Examples are carboxymethylcellulose, methylcellulose, guar gum, Irish moss extracts, locust-bean gum, alginates, partially hydrolysed corn starch, corn, syrup, invert sugar syrup, lacvulose, corn-syrup solids and sorbitol. The sugar may be sucrose or dextrose. The product may be made by wetting particles substantially only by condensing moisture on them to form adhesive surfaces, so that they stick to each other in the form of porous agglomerates. This may be done by suspending them in a fluidized bed in a current of steam which is hot enough in the lower part of the bed for condensation to be avoided but cool enough in the upper part of the bed for it to take place. The product may also contain a flavouring agent, e.g. maple flavouring, cocoa and dry milk solids, fruit flavouring and fumaric acid, butterscotch or caramel. When the conditioning agent is in liquid form, the sugar may be ground in the presence of the conditioning agent so that the latter is spread over the particles as a minute film, so that the material feels dry to the touch, before agglomeration. Reference has been directed by the Comptroller to Specification 920,261.

IPC: F01K3/26
Filed: 1968-05-31
Abstract: 1,263,473. Turbine plant. FOSTER WHEELER JOHN BROWN BOILERS Ltd. May 28, 1969 [May 31, 1968], No. 26341/68. Heading F1T. [Also in Divisions G4-G6] In a steam (or like vapour) turbine plant the steam (or other vapour) is reheated between high and low pressure turbine stages 12, 14 by heat exchange in exchanger 22 with live steam from upstream of the turbine stage 12, the quantity of live steam passing through the exchanger 22 being so great that not all of it condenses. The exchanger 22 is of the shell and tube type, the live steam passing through, and the heated steam over, the tubes. The excess live steam prevents traces of non-condensable gases, e.g. oxygen, nitrogen or carbon dioxide, present in the live steam, particularly when the heat source 10 is a boiling water nuclear reactor, from accumulating at the ends of the tubes and reducing efficiency. The steam, gases and water condensate from the tubes are passed to a separator 26 where the steam and gases are separated from the water. The latter is fed to feedwater heaters 30 whereas the steam and gases are passed through line 28 and selectively through lines A and/or B and/or C to the inlet or an interstage point of turbine stage 12 or to the feed heaters 30. The gases eventually collect in the condenser 16 from which they are removed by a small continuous purge or by a de-aerator. The steam to be reheated may pass through a drier 20 before entering heat exchanger 22, or alternatively an additional heat exchanger may be used.

Filed: 1959-08-05
Abstract: 926,046. Transistor amplifier and limiter circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 5, 1959 [Aug. 8, 1958], No. 26751/59. Class 40 (6). A transistor amplifier has the emitter base path of an auxiliary transistor connected for D.C. across the collector to base path of the amplifier transistor to produce a control signal in the auxiliary transistor which controls the level of the signal applied to the amplifier. In Fig. 1 transistor output stage 3 has the base emitter path of an auxiliary transistor connected between collector and base so that when the collector potential falls to a predetermined value the transistor 4 conducts, producing across a smoothing network 6, 7 a D.C. control voltage for reducing the amplification of a preamplifier stage 2. This avoids distortion due to the collector base junction of transistor 3 becoming forward biased on over load. The gain of transistor 2 could alternatively be controlled by applying the voltage across the network 6, 7 to the collector of the transistor. In an alternative embodiment (Fig. 2, not shown), transistor 4 is replaced by an NPN transistor, the smoothing networks 6, 7 is connected to the emitter of the pre-amplifier transistor 2. The voltage from the smoothing network could be applied in the reverse sense to the pre-amplifier, for example by connecting the output of the auxiliary transistor 4 in the second embodiment to the base of the pre-amplifier transistor so that peak limiting occurs. Capacitor 7 may be omitted, in which case negative feedback occurs when the transistor 4 becomes conductive.
