Abstract: 1291085 Controlling furnace burners WESTINGHOUSE ELECTRIC CORP 30 Oct 1969 [5 Nov 1968] 53210/69 Heading F4B The distribution of heat within an enclosure from a burner is controlled by using a first effect of the burner heat to control the amount of fuel supplied to the burner and the amount of air/inert gas mixture required to transport the fuel to the burner, and using a second effect of the heat at a point remote from the burner to control the amount of inert gas supplied so as to regulate the length of flame produced. The distribution of heat in a kiln 10 fired by a pulverulent fuel burner 12 is controlled by a computer 20 which regulates the amount of fuel fed to the burner through a rotary valve 16, the total amount of combustion air supplied through fan 24, and amount of recirculated waste gas supplied to the burner through fan 22 and damper 80, and the proportion of air fed to duct 86 as primary air and the proportion fed as secondary air. The fan 22 also supplies gas to a pulverizer 46. The air/waste gas ratio in the mixture used to feed the fuel to burner through duct 81, and the primary/secondary air ratio both affect the flamelength. The total amount of waste gas and air flowing in the duct 86, and the total amount of combustion air are controlled in accordance with the desired fuel supply. The arrangement may be applied to a boiler.

Abstract: 1441129 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 26 Nov 1973 [29 Dec 1972] 54762/73 Heading G4H [Also in Division H4] In a multiple-unit communication system, each of a plurality of the units is capable of receiving data and includes a frame generator and a frame-monitor-and-data-extractor defining the start and finish of a distinct loop frame transmission path to which the remaining units have access only by way of frame processing means for inserting data into an extant frame whereby the network is receiver-driven. As disclosed, the units are the CPU and subsystems of a computer, and each unit can receive data from any of the others by way of a loop as above respective to the receiver. Transmission is serial by bit in each loop. The frame generator of a unit can generate "empty" frames up to the number of empty input buffers, and any of the other units can send information to this unit by converting one or more frames to "full" frames in their frame processing means. The frame processing means and the framemonitor-and-data-extractors synchronize on the beginnings of frames. "Idle" frames can also be sent merely to synchronize. "Full" frames are used to demand data transfer (involving reading from or writing into a store at the unit which receives the frame) or to demand control transfer, and the unit receiving either of these varieties of frame responds with an appropriate response "full" frame in the appropriate other loop. Each frame contains bits to specify its type, and the various varieties of "full" frame also contain the number of the originating unit, a demand-response correlation field, check information, and where appropriate storage protection key, data, address, byte-selecting bits, etc.

Filed: 1965-12-30
Abstract: 1,133,219. Radioactive seeds. HAZLETONNUCLEAR SCIENCE CORP. 30 Dec., 1965, No. 55199/65. Headings A5B and A5R. [Also in Division H5] A radioactive seed for use in radiation therapy comprises a sealed container having uniform thickness walls made of a material having an atomic number of 4 to 28 containing a soft X-ray emanating isotope whose characteristic radiation lies between 20 and 100 Kev and whose half life is 5 to 100 days, and whose radiation is free from α, B and high y energy and radiations. The isotope is on a carrier having a low absorption for soft X-rays, e.g. an organic polymer such as nylon or P.T.F.E., or a rod extruded from cellulose acetate, acetone and ammonium phosphomolybdate. The carrier may be disposed axially within the container. Specified isotopes are: I-125, Cs-131, Pa-103, Xe-133 and Yt-169. The I-125 can be absorbed onto a nylon rod to give 5 millicuries of I-125/cm; the Cs-131 can be absorbed onto the ammonium phosphomolybdate rod; and the Pa-103 can be plated onto a plastics rod (nylon). The sealed container is elongated and may be small enough to pass through a hypodermic needle e.g. 4mm x 0.5-1.0 mm. The container may be made of stainless steel, Ti, Be coated with a non-toxic material, e.g. Au, or Al (which latter may be covered with an inert plastics material, ceramic or precious metal) or a plastics e.g. fluorinated hydrocarbon, nylon, silicone rubber or polyester resin. The seed may contain a means for blocking X-rays so placed to make the seed X-ray visible while giving a uniform radiation pattern and minimal absorption of the radiation, e.g. a rod or ball of Au or W, disposed axially or centrally respectively within the seed. The seed is made by impregnating the carrier with the radioactive material and then sealing it in the container by swaging, fusing, welding or by joining the walls together under pressure. If a plastics cover for the container is used, it can be heat-shrunk onto the container. In use the seed is injected permanently into the body to irradiate tissues, the radioactive material being selected so that it will have decayed by the time treatment is complete.

[Also in Division F1] In a carburettor the air passing through an inlet chamber 28, Fig. 1 is given a simple cyclonic motion having an axial component and a rotational component and during its flow through an outlet chamber 18 undergoes a compound cyclonic motion having a first rotational component about the axis of the outlet chamber arid along a directional line which curves around that axis and a second rotational component about the directional line. Air enters through filter 76, Fig. 2 and passes through a choke valve 78 and tangentially directed inlet passages 36 into housing 38 and thence into inlet chamber 28. Fuel passing through inlet 60 of nozzle 54 is atomized by air delivered through inlet 62. The swirling mixture enters chamber 18 tangentially between wall 20 and baffle 4 and follows line 52, Fig. 2 with compound cyclonic motion. Part of the mixture flows inwardly through the upper end of baffle 46 and the remaining pant flows round the lower end of baffle 46 to the outlet 26 and thence past butterfly valve 108 to the engine inlet manifold 104. Throttle valve 108 and needle valve 66 in the atomizing nozzle 64, together with a valve 120, are moved conjointly by an accelerator pedal. The nitrogen oxides present in the exhaust gases are reduced by recycling part of the exhaust gas through the valve 120 and conduit 118 to the engine intake. Valve 120 cuts off the exhaust gas flow when the valve is in the idling or full throttle positions. Fuel deposited by centrifugal action on the inner walls of chambers 28 and 18 is vapourised by heat from exhaust gases passing from inlet 94, Fig. 2 through jacket 82 to a thermostatically controlled valve 98 leading to outlet 92. In another embodiment the outlet chamber Fig. 5 (not shown) has six outlets.(26'), each containing a throttle valve (108'). which connect with the intake ports of particular cylinders.
