Title: Steam generating plants operating at supercritical pressure and temperature
IPC: F22B29/06
Filed: 1954-09-07
Abstract: 752,529. Critical pressure boilers. SULZER FRERES SOC. ANON. Sept. 7, 1954 [Sept. 8, 1953], No. 25889/54. Class 123(2). A steam &c., power plant comprises a steam generator 4 normally operating at supercritical pressure supplying steam to a turbine 7 exhausting into a condenser 9 from which condensate is delivered by a pump 10 into a hot well 1. A feed pump 2 supplies water from the hot well to the tube system of the generator. To prevent the formation of steam bubbles in the boiler tubes with consequent uneven distribution among the tubes of the working medium, a supercritical pressure is maintained in the boiler at all times, that is, during starting, warming-up, normal and low load operation and shutting down, a turbine by-pass pipe 13, having two reducing valves 12, 20 respectively controlled by pressure sensitive devices 21, 22, being provided to connect the boiler tube outlet directly to the hot well. During starting, the turbine shut-off valve 5 is closed and water pumped into the tube system and through the by-pass, the devices 21, 22 being set to ensure that valves 12, 20, whilst allowing the passage of tubecooling water, maintain a supercritical pressure in the boiler, the furnace being lit only after this pressure has been reached. During the later stages of warming-up the superheater outlet pressure is gradually reduced to the desired operating pressure the feed water and fuel supplies being automatically regulated during normal operation to maintain this pressure. In modifications, excessive wear on the by-pass valves during starting is avoided by by-passing the valves by a pipe having either a pressurereducing valve or orifice plate and shut-off valve which are placed in circuit only during starting.

Title: Rollways in shearing lines
IPC: B26D7/01
Filed: 1970-06-01
Abstract: 1308025 Metal sheet feeds MOELLER & NEUMANN GmbH 1 June 1970 [2 June 1969] 26290/70 Heading B3W A delivery roller table comprises a direct current section G and a three-phase section D both operating at substantially the same speed to reduce slip at the joint between the sections, and each being at least as long as the maximum length of plate to be cut by shears 2. The rollers of section G have a common or connected drive and the rollers of section D are brought into action progressively by signals from detectors such as photo-electric 52, 54, 56, 58 mounted ahead of each roller or group of rollers of the section D and actuated by the passage of a plate. Rollers 7 immediately after the shear can be driven through a line 11 in common either with a feed roller bed Z, if the length to be cut off does not extend beyond the rollers 7, or with the remaining rollers of section G for longer cut-off lengths. The cut length may be controlled by a stop 18 or by a length measuring roller (not shown). A feed line 30 for threephase current is supplied through a switch 28 mechanically coupled to a switch 14 controlling the direct current supplied to rollers 8 and 10 of section G. With a plate at position B2 and direct current being fed to line 30 due to the coupling of switches 14 and 28, rollers 22 and 24 are unaffected because switches 37 and 39, in branch lines between feed line 30 and rollers 22, 24, are still connected to a run-off line 40. The plate B2 having actuated the photo-electric devices 52 and 54, switches 33 and 35 have been changed over to the feed line 30 which drives the rollers 20, 21 at the same speed as the rollers of section G. When the plate B2 moves on to cover and thus actuate photo-electric device 56, the rollers 22 will also be connected to feed line 30. The plate B3 when as shown it covers photo-electric device 58 also causes rollers 24 to be connected to the feed line 30 unless gating devices are associated with interrupter switches 55, 57, 59 whereby these switches are opened and kept open if any preceding photo-electric device is not covered, e.g. the device 56 at a gap between two plates.

Title: Improvements in and relating to the sorting of small articles
IPC: B07C5/342
Filed: 1948-10-12
Abstract: 652,782. Sorting photo-electrically. OKOLICSANYI, F., and GUNSON (SEEDS), Ltd., R. W. Oct. 12, 1948, No. 26511. [Class 40 (iii)] In apparatus in which articles, e.g. seeds, are sorted according to colour by selective charging under the control of photo-electric cells the seeds are fed to an inspection position in a series of single files, the end-seed of each file being examined successively and the charging apparatus connected to each end position in turn. The end seed of a file is shown in Fig. 1. A light beam reflected from mirror drum 19 traverses all these end seeds and an identical drum 22 on the same shaft receives reflected light from each seed in turn and transmits it to a photo-cell (not shown). All the seeds may be illuminated at once in which case only the photo-cell drum is necessary or the photo-cell drum may be omitted and each seed illuminated in turn. The mirror drums are driven by a motor 21 which also drives a rotating switch arm 28 to connect the tips of each shoot along which the seeds advance, to the charging apparatus at the same instant as the photo-cell examines it. The beams may be charged by means of metallic tips on the supply shoots as disclosed in Specification 617,276, or by means of a corona discharge as disclosed in Specification 642,284. Specification 642,283 also is referred to. The seeds may be fed to the inspection points by means of a jigging conveyer. The Specification also describes an arrangement for charging each tip in turn (Figs. 5, 6 and 7, not shown), in which a rotating charging arm passes close to contacts connected to each of the tips, thereby charging them by induction. A plate rotating with the arm earths each tip successively when the seed on it is not being examined. In the arrangement of Fig. 8 a triode 37 is connected in the H.T. supply line from the amplifier to the charging arm 39 wiping contact 40 connected to the tips. The triode is blocked by an arm 41 just before arm 39 leaves one of contacts 40, thereby preventing sparking.

Abstract: 297,675. Reischach & Co., Ges. Sept. 24, 1927, [Convention date]. Immunizing and like serums.-Serums for use in the prevention and treatment of tuberculosis are prepared from living animal tissue which has been disintegrated by the action of tubercle bacilli, instead of from artificial cultures as usual. According to an example tubercles are removed from lung or other tissues of infected cattle, divided in halves and the caseous matter removed and extracted by means of a solution of 10 gms. common salt in 100cc. of glycerine, together with 0.1 gms. trypaflavine in 100 cc. of 1 per cent phenol solution. The mixture is allowed to stand, filtered, and the residue dried and ground. The filtrate may be sterilized by filtration and used alone for preventive inoculation, or the ground residue may be added thereto for innoculation, of an animal to obtained blood or milk serum or lymph for curative purposes. In the latter case the material may be introduced intracutaneously into the animal to produce local centres of infection. The inflammation which sets in is maintained bv the application of a suction cup or cups and lymph is obtained by scarification. Blood is then drawn off for the preparation of the serum. The serum and the lymph may be used separately or together for medical treatment.

Abstract: 1294175 Electrolytic production of manganese dioxide BECEKA-MANGANESE SA 2 June 1970 [3 June 1969] 26621/70 Heading C7B A cell for the electrolysis of a manganese salt to produce manganese dioxide has a removable bottom 10 upon which anodes 6 are secured, so that the solid, coherent precipitate of manganese dioxide may be removed with the anodes by removal of the cell bottom. The anodes are elongate, e.g. of circular, polygonal or elliptical cross-section; and may be of titanium. The cathodes 4, also rod shaped may be secured to the lid 8 of the cell, and each may be positioned at the centre of a hexagon of anodes. Agitation of the bath may be produced by use of mechanical stirrers and localized heating; and hollow cathodes having upper and lower openings may be used, an air-lift effect causing electrolyte to rise through the cathodes, or the cathode may be surrounded by a diaphragm, flow occuring between the cathode and diaphragm - Fig. 2 (not shown). The titanium anodes may be tubular, being coated internally with a more highly conductive metal, e.g. copper zinc, nickel or chromium, and the connecting wire may be embedded in a low melting point metal. Internal coating of the anodes with copper may be effected electrolytically, e.g. by making the titanium to be coated cathode first in an aqueous sulphuric acid bath, which effects pickling of the titanium surface, and thereafter adding copper sulphate to the electrolyte. In the production of manganese dioxide a heat-insulator such as paraffin may be present on the surface of the bath.
