Title: Vapor turbine power plant
IPC: F01K7/40
Filed: 1965-06-21
Abstract: 1,049,277. Turbine plant. WESTINGHOUSE ELECTRIC CORPORATION. June 21, 1965 [June 22, 1964], No. 26157/65. Heading F1T. [Also in Division F4] A steam or ammonia vapour power plant comprises a vapour generator 15 supplying high and low pressure turbine cylinders 11, 12 in series exhausting into a condenser 23. The water or liquid ammonia from condenser 23 is pumped through line 26 into parallel feed heater lines 24, 25 comprising respectively, heaters 31 to 35 and 36 to 41. Each heater is supplied with bled heating vapour from an extraction point 52 to 54 or 65 to 71 in an appropriate stage of turbine cylinders 11, 12. Each extraction point is associated with a device for collecting condensation liquid from the working vapour flowing through the turbine. The collecting device comprises, Figs. 2, 3 (not shown), a part-annular shield 56 surrounding the rotor blades 45 and mounted on the upstream stator blades 49 to define an annular gap 57 through which the condensation liquid is thrown out centrifugally and entrained with the bleed vapour also flowing through the gap. The liquid/vapour mixture flows round the annular channel defined between shield 56 and outer casing 43, through openings 61 into a chamber 62 and thence through line 64 into the appropriate feed liquid heater. The vapour condenses in the heater and the condensed vapour is fed through an outlet 76 to the adjacent lower temperature heater in the same feed line and is finally returned from the lowest temperature heaters 31, 36 through lines 79, 80 respectively to the condenser 23. To ensure that the feed liquid in lines 24, 25 is heated to the same terminal value before flowing into the common line 28 leading to vapour generator 15, the highest temperature heaters 35, 41 are supplied with heating vapour from a common bleed point 52, heater 35 receiving twice as much vapour as heater 41 since the temperature differential between heaters 34 and 35 is twice that between heaters 40 and 41. Control valves V 1 , V 2  are provided in the feed and bleed lines. In a modification, Fig. 4 (not shown), the condensed bleed vapour from each feed heater is fed to the adjacent higher temperature heater in the other feed line 103, or 104 before being returned to the condenser.

A partition comprises glazed panels located between mullions having detachable coverplates concealing spring clips which hold both the cover-plates and the glazed panels, together or independently, in position. As shown, the partition supporting posts 12 each have a fixed part 121 (Fig. 8) of roughly U-shape, the legs being cranked in towards each other, and tuned again to provide mutually parallel ends to the legs. These mutually parallel sections are cut out for short distances up the posts to allow the entry of spring clips 32 having protruding curves 36 at their ends which hold the coverplates 122, and also the lower partition members 13 or glazed panels 14 in position. Above the glazed panels, a horizontal framing member 17 is also formed in two parts, with a fixed part 171 screwed to the posts 12 having initially divergent end portions which are forced together by, and hence hold in position, a detachable portion 172, which in turn helps to support the glazing panels 14, which are protected by a U-sectioned glazing strip 30.

Abstract: 603,309. Transformers. PATELHOLD PATENT VERWERTUNGS- & ELECTROHOLDING AKT.-GES. Oct. 12, 1945, No. 26696. Convention date, Oct. 12, 1944. [Class 38 (ii)] In iron powder magnetic cores suitable for audio and high-frequency apparatus parts of higher flux density are given higher permeability. Such parts are preferably of simpler shape than the others on account of lower mechanical strength. These parts of higher permeability may be made from a mixture of the same materials as the others but with a greater proportion of iron powder by weight and subjected to a higher compression in manufacture. In the Figure, the part 1 of the dust core which is surrounded by the coil 3 carries a higher flux density than the remaining part 2 of the core and is of material having a higher permeability. To allow of adjustment of inductance the core part 1 is axially movable by means of the screw thread 4 which is preferably formed in artificial resin glued or pressed on to the core. The permeability of core part 1 may vary along its length. In a modification the part 1 is immovably held in the core part 2 which is split into two similar halves held together by an artificial resin or sheet metal casing and supported on a rubber or felt pad. The part 1 may. be interchangeable with other similar parts of different permeability. According to the Specification as open to inspection under Sect. 91 the invention might be applied to a generator or motor, the poles having a greater permeability than other magnetic parts. This subject-matter does not appear in the Specification as accepted.

Abstract: 503,209. Coin - freed article - delivery apparatus. FITZPATRICK, H. J. (Maatschappij Van Berkel's Patent N. V., and Berkel, C. F. M. Van) Oct. 2, 1837, No. 26706. [Class 27] In a coin-freed machine having a plutality of magazines 1, 2, Fig. 1, from which articles are delivered, a reserve stock 3 for automatically replenishing the articles in magazine 1 which contains articles of larger size or quicker sale and so is liable to be exhausted more quickly than the magazine 2, is stored on a platform 6 above the articles in magazine 2. The platform 6 is connected by a lever 7 with a slide 9 having a roller 11, Fig. 2, which engages a cam face 13 on one side of a lever 12 pivoted at 21 to the delivery drawer 5 of the quick sale magazine 1. When the. drawer 5 is, pulled out, the roller 11 causes the lever 12 to rock so that a projection 14 on its other side passes normally under a plate 19 pivoted at 20 and held up by the toe 18 of a lever 16 pivoted at 17 and urged by a spring 22 so that a feeler 15 on its upper end is pressed against the articles in the magazine 1. The feeler 15 is disposed at about the same level as the platform 6 and, when the articles in magazine 1 fall below this level, the lever 16 is rocked to release the plate 19 which falls into the path of the projection 14 on lever 12. During the next actuation of the drawer 5, the lever 12 cannot move and the cam 13 moves the slide 9 to rock the lever 7 and carry the platform 6 with its pile of articles on to the top of the pile 'in magazine 1, the articles moving freely past pivoted angle irons 23, the arms 24 of which can move inwards only. These arms prevent the pile 3 from moving back with the platform 6 when this is returned by pushing in the drawer 5.

Input liquid is supplied to the ports S and is equally divided between ports A and B. Source liquid S is supplied to both ports 1 and in cylinder 1 flows through a chamber 30, out of a port 4 and into chamber 21 in cylinder 2 to push the piston to the right. This displaces liquid from a chamber 22 of cylinder 2 on to a chamber 33 of cylinder 1 through a port 5. From here it goes out through a port 2 into line B. As the piston in cylinder 2 moves to the right ports 4 and 3 are connected and ports 5 and 1. Liquid from port 1 of cylinder 2 now flows through port 5 to the chamber 31 of cylinder 1 so that the piston in cylinder 1 begins to move to the right. This displaces liquid from a chamber 32 through port 4, chamber 24 of cylinder 2 and port 3 to line A. This movement of the pistons continues, one leading the other and liquid is alternately fed to lines A and B. In a similar manner inputs to lines A and B may be combined in equal volumes and fed out at lines S. Other embodiments are illustrated and described which employ several pairs of units.

Title: Process for producing permanent pigments
IPC: C09C3/06
Filed: 1925-10-28
Abstract: 242,282. Deutsche Gasgl³hlicht- Auer-Ges. Oct. 31. 1924, [Convention date]. Pigments.-Pigments of a permanent nature which will not affect the oil with which they are afterwards mixed, are obtained by neutralizing any residual traces of free acid adhering to the particles by addition of zinc oxide or hydroxide in aqueous suspension, usually in amounts of about 5 per cent. The product is then filtered, washed, dried and heated to incandescence. The process is particularly applied to titanium oxide either alone or mixed with barium sulphate or other pigments. The titanium oxide is first washed and then treated with alkali; any small amount of free acid remaining is then neutralized with excess of zinc oxide. Neutralization can also be effected by kneading the moist titanium oxide with zinc oxide, the alkali treatment being omitted. The pigments thus obtained may be mixed with other white or coloured pigments; or additional quantities of zinc oxide, barium sulphate &c. may be added prior to the final heat treatment. Specification 105,962 is referred to.
