Patent FI-972178-A (FI)
Inventor: SHELOR F MACK
IPC: F23C7/06
Filed: 1997-05-22
Abstract: A method of using internal combustion engine exhaust in a combined cycle power plant is disclosed, wherein the quality and distribution of exhaust to the boiler space of a steam generated electric power plant is controlled to achieve greater system efficiencies. Outside air is blended only with that portion of the exhaust that passes through the burner ports as secondary or higher level combustion gas. The remainder of the exhaust is provided to the boiler space by a route other than through the burner. The highest overall system efficiencies are achieved where the amount of outside air blended with the portion of exhaust that passes through the burner is such that the blend contains about the minimum amount of oxygen required for complete and stable combustion of the selected fuel, where a substantial percentage of the total exhaust is routed to the boiler space by a route other than through the burner, and where the amount of fuel is sufficient to achieve a desired boiler entering temperature upon its combustion.

Abstract: 575,492. Feeding webs. WILLIAMSON, C. W. Jan. 24, 1944, No. 1311. Class 100 (i)] [Also in Group VIII] A web-severing machine which is especially applicable to photographic printing and other machines, is constructed with guillotine blades 22, 25, Fig. 3, the operation of which is controlled by a space - determining means set into action by means adjacent the guillotine for detecting apertures in the web. The apertures cause operation of a single-cycle operating mechanism comprising crank discs 51, Fig. 1, which oscillate a shaft 31 by means of which the movable blade 25 is operated. The web is fed forward by measuring rolls 7, 9, the roller 7 being driven from a main driving-pinion 34 by means of pinions 35, 36, 37 and a friction clutch, and the web passes behind a flat surface 11 with apertures to permit the action of a further measuring roller 14 with which coacts a spring-pressed roller 15, which can be turned aside to permit of threading of the web. The roller 14 is driven by a gear 47 in mesh with a gear 46 driven by the gears 35, 36, 37. The discs 51 commence their cycle of operation when one of a series of feeler levers 76 engages an aperture in the web and causes a switch 76 to close and energize a magnet 73, causing attraction of an armature 72 and clockwise movement of a lever 69 which sets in motion a space-determining lever 61 by forcing a pawl 66 into engagement with the wheel 46. The cutters are then actuated by means as described in Group VIII.

Title: Powder mixtures suitable for use in powder metallurgy
Inventor: HILL JAMES SPENCER
IPC: B22F9/00
Filed: 1966-01-11
Abstract: 1,099,581. Making metal powder mixtures. ENGELHARD INDUSTRIES Inc. Jan. 11, 1966, No. 1322/66. Heading B3A. [Also in Division E1] A method of making a metal powder mixture comprises separately atomizing first and second molten metals and obtaining powders thereof, the standard density of the first metal being less than that of the second metal, reducing the apparent density of the second powder to substantially that of the first powder by flattening it to flakes and thereafter mixing amounts of both powders. A selected volume of the lighter powder is allowed to fall freely into a vessel to determine its apparent density or the powder mass may be fluidized by passing gas therethrough and then allowing it to settle loosely. The heavier powder is mixed with a lubricant, and the powder particles are flattened in a ball mill. The apparent density of the latter powder is then determined and when the apparent densities of both powders are substantially equal they are mixed in the required proportions. The lighter of the two powders may be aluminium, which may be mixed with copper, nickel, zinc or tin or alloys thereof. Alternatively a copper-gold-nickel alloy powder may be mixed with aluminium, magnesium or iron. Since in all cases the heavier metal powder is in flake form, the mixture remains stabilized against the settling out of the heavier metal.

Title: Improvements in pumping and vaporizing liquefied gases
IPC: F17C5/02
Filed: 1957-01-15
Abstract: 847,508. Revaporizing liquefied gases ; forcing liquids by gaseous pressure. AIR PRODUCTS Inc. Jan. 15, 1957, No. 1442/57. Classes 8(2) and 102(2). Liquefied gas e.g. oxygen, forcing and revaporizing apparatus comprises a heat insulated low pressure supply vessel 10 connected by a vapour duct 14 and a liquid gravity feed duct 13 to a heat insulated transfer vessel 12, a reservoir 24 heated by ambient atmosphere and connected by a vapour duct 26 and by a liquid gravity feed duct 25 to the transfer vessel and connected by a valved duct 33 to vaporizor exchangers 34, 35 which discharge vapour at fiigh pressure to a cylinder 11 ; the ducts 13, 14 having back pressure closing valves 15, 16 operating at relatively low pressures to allow pressure in vessel 12 to rise to that in reservoir 24 when a valve 28 controlling the vapour duct 26 is held open by a float 31 abutting a stop 32, assuming a back pressure valve 27 in duct 25 being in the open position. In starting and with valves 20, 15, 16, 27, 28 open, liquid flows by gravity from vessel 10 to vessel 12 and from there through duct 25 to reservoir 24 until the latter is filled whereupon valve 28 is closed by the float 31 after which the transfer vessel fills up. Inflowing ambient heat then raises the pressure in reservoir 24 sufficient to close valve 27 and force liquid through duct 33, the valve 36 and vaporizor exchangers 34, 35 and thence to the cylinder 115 the valve 28 being held closed by the pressure in reservoir 24 until the liquid level falls sufficiently for it to be opened by the float 31. At this time the pressure in vessel 12 is increased to that in reservoir 24 resulting in closing of valves 15, 16 and opening of valve 27 whereon liquid flows from vessel 12 to reservoir 24 to refill the same. Values 27, 28 then become closed, the pressure in vessel 12 is then reduced by condensation caused by passage of cold liquid through a coil 17 sufficiently to allow valves 15, 16 to open whereupon the vessel 12 is refilled during a time interval shorter than that during which the reservoir 24 is emptied. In a modification the supply vessel comprises the base of the low pressure zone of a conventional double-column air rectification apparatus and the reservoir valve 75, Fig. 2 (not shown), corresponding to valve 28 of Fig. 1, is operated by a member 85 controlled by a temperature responsive device 84.

Abstract: 1470391 Labelling articles GEC ELLIOTT AUTOMATION Ltd 11 Feb 1975 [14 Jan 1974] 01722/74 Heading B8F [Also in Division G4] A method of identifying an article comprises storing information regarding the article in serial form extending along the length of a strip of material, securing the strip to the article at one end only and automatically reading out the stored information, whilst the strip is secured to the article. The label consists of a strip of flexible non-magnetic material, e.g. polyvinyl chloride or polyester foil, coated on one side with a magnetic material. The price, stock number and other information of a relevant article to be sold are stored on each label as a serial magnetic low density recording using binary coded decimal representation. Some information may be carried visually on the strip. A high coercivity magnetic ferrite coating may be used for the labels. The labels are attached by adhesives using a label dispenser. The adhesive may be of the cyano-acrylate group and applied using a peristaltic pump or comprise a hot melt adhesive in the form of fine wire. The labels are prepared using a label encoding and printing machine and the ends to be attached to the articles are identified by slitting or punching. A label reader is shaped to fit the hand and grips the label to allow a wheel containing a reading head to scan the magnetically coded part of the label longitudinally. A valid transfer of information to a control and display unit results in automatic cut off of a major part of the label. The cut is of complex form so that unregistered removal is easily detectable. The part of the label remaining on the article may include printed information. Information read off of the label is entered into a buffer store, checked for errors, and transferred to a static memory. The equipment at a sales point for reading and transferring the information comprises a label reader, a magnetic tape recorder, an electronic cash register, a till, a receipt printer an automatic change dispenser and an automatic control and display unit. The data stored in the tape recorder is subsequently transferred to a data processing centre.
