Abstract: 1,188,935. Blind riveting. G. K. N. SCREWS & FASTENERS Ltd. 1 Aug., 1967 [1 Sept., 1966], No. 38970/66. Addition to 1,128,442. Heading B3U. A tool for blind riveting similar to the tool of the parent ease comprises a mandrel holder 18 mounted in the body of the tool for axial and rotational movement so that the end of the mandrel drills a hole in the work into which the rivet is inserted. The holder 18 is rotated by an air motor in the handle 11. The motor rotates a shaft 13 which has a piston 14 mounted thereon so that the introduction of compressed air into spaces 24, 25 moves the holder axially. Initially a rivet 30 is threaded on the mandrel 35 which has a bit 36, the mandrel is inserted in the holder against a stop 38 and the tool moved adjacent the work, Fig. 3 (not shown). The mandrel is rotated to drill the work and the rivet forced through the hole by the end cap 5 when air is allowed into the chamber 24. The mandrel is then withdrawn by air entering the chamber 25 and deforms the rivet. The end of the mandrel snaps off and may remain in the rivet, Fig. 6 (not shown).

Title: Pressurized water reactor including a boron concentration measuring apparatus
IPC: G01N1/00
Filed: 1976-09-23
Abstract: In the instrument, the boron density is measured automatically and continuously by determining the conductivity of a mixture of a boric acid sample water and a mannite solution. The temperature of the mixture flowing through is registered by a temperature-sensitive element (18). This is connected in a measuring circuit (14) of an instrument (16) for measuring the electric conductivity, which circuit is connected to a conductivity-measuring electrode (12). This arrangement corrects any errors in the conductivity measurement, which are caused by variations in the temperature of the mixture flowing through. <IMAGE>

Title: Boiler feed supply apparatus intended particularly for locomotives
IPC: F22D1/42
Filed: 1929-12-24
Abstract: 343,251. Steam boiler feed supply systems. FRIEDMANN, L., FRIEDMANN, M., and SCHOPP, N., (trading as FRIEDMANN, A., [Firm of]), 6, Am Tabor, Vienna. Dec. 24, 1929, No. 39485. Convention date, Jan. 8. [Class 123 (ii).] In feed-supply apparatus for locomotives, comprising a tank 18 for storing preheated water, means are provided for feeding the boiler when the steam regulator is closed, both from the storage tank 18 and from the cold feed tank, the boiler being fed when the regulator is open, only from the cold feed tank. To supply hot water from the storage tank when the regulator is closed, a control valve 23 in the apparatus is opened and a valve 17 is closed. Boiler steam then flows through pipe 7, chamber 44, valve opening 36 and pipes 11, 12 into the upper part of the storage tank, from which the hot water flows into the boiler through the clack valve 22. When the valve 17 is opened, and the boiler steam flows through pipe 10 and chamber 17 to an injector 49 drawing cold water from the tender through a pipe 2 and forcing it into the boiler through pipes 9, 13 and the clack valve 19. The pipe 13 may open into the boiler through an injector nozzle assisting the supply of hot water to the boiler from the storage tank. When the regulator is open and no feed is required, the valve 23, 17 are closed and the pressure of the boiler steam in the pipes 4, 5 opens valves 39, 30 controlling respectively the entrance of cold water to the feed injector and the opening of the exhaust-steam admission valve 33 by the steam pressure acting on a piston 32. The exhaust steam flows through a nozzle 46 mixes with the cold water in a combining nozzle and forces the mixture through pipes 9, 14 into the storage tank. If feed is required when the regulator is open, the valve 23 is opened to allow boiler steam to flow through pipe 7, chamber 44, valve 26, pipe 8 and valve 41 into the live steam nozzle 49, from which the boiler steam flows together with the exhaust steam flowing through the nozzle 46, into the mixing nozzle, and thence the mixture of steam and cold water flows through pipes 9, 13 and clack box 19 into the boiler.

Title: Naphtha reforming process
IPC: C01B3/38
Filed: 1962-10-22
Abstract: <PICT:1003147/C1/1> A gas stream of H2, N2, H2O, CO and CO2 is made by forming a stream at at least 1000 DEG  F. by mixing hot naphtha vapour at up to 1000 DEG  F., superheated steam, and hot air, allowing the mixture to react for less than 1.0 sec., then contacting the mixture with a reforming catalyst at at least 1400 DEG  F.  The naphtha consists mainly of straight-chain C5- 9 paraffins; up to 30% naphthenes and up to 10% aromatics and unsaturated hydrocarbons may be present, with some COS and mercaptans.  The product stream is free from hydrocarbons, and free carbon deposits do not accumulate.  In the Figure, liquid naphtha 1 is vaporized and preheated in heater 2; the naphtha vapour stream 3 may be at 400-800 DEG  F.  Steam stream 4 which may be at 1500-1700 DEG  F. and air stream 5 at 800-1200 DEG F. may be mixed forming stream 6 at at least 1100 DEG  F., which is then mixed with stream 3 to form mixed stream 7, at 1000-1700 DEG F., which is then passed into chamber 8, which may be an insulated pipe, or streams 3, 4 and 5 may be separately passed to chamber 8, where reactions take place, and the temperature of the stream rises, e.g. to 1450-1500 DEG  F. or above 1600 DEG  F. The range of ratios of steam molecules: carbon atoms is 3: 1 to 7: 1.  The proportion of air may be that required to produce a H2: N2 molar ratio of 3: 1 in the product.  The residence time in 8 is preferably 0.05-0.33 sec., after which the gas stream 9 enters catalytic reformer 10, provided with more than one reformer tube 11 containing reforming catalyst 12, e.g. Ni or Co on a carrier, with or without inert diluent, e.g. porcelain, in the upper part. Preferably stream 9 is divided into a plurality of partial streams which are passed into contact with the catalyst at a plurality of spaced intervals.  Tube 11 is heated externally, e.g. by burning fluid hydrocarbon streams 13 with air streams 14, the gases leaving at 15. Temperatures may be not less than 1400 DEG  F. where free oxygen is present, and not less than 1600 DEG  F. otherwise.  The "equivalent velocity" of the stream in 11, i.e. the velocity the stream would have were catalyst 12 absent, is at least 5ft./sec.,preferably 10-30ft./sec. Operating pressure may be 100-300 p.s.i.g.  The resulting product stream leaves via 16, containing, by volume, about 50% steam, and on a dry basis 51.4% H2, 22.5% N2, 13.0% CO2, 12.1% CO, 1% CH4 and 0.0% unsaturated hydrocarbons.  From this a 3: 1 H2 : N2 gas mixture may be obtained by known means.  U.S.A. Specifications 2,660,519 and 2,801,159 are referred to.

Abstract: 1,190,168. Road traffic signals on vehicles; visible signalling-apparatus. WAGNER ELECTRIC CORP. 21 Aug., 1968 [21 Aug., 1967], No. 39900/68. Headings G4F and G4Q. [Also in Division H1]  In a flasher circuit, including a power source 15 connected to a relay 14, a flasher 18 connected to the relay and a load having a non- linear resistance characteristic, such as lamp 30, connected to the flasher, the relay 15 is operative when a switch 28 is closed to shunt the flasher during an initial portion of the time period when the flasher contacts are closed. Normally the on time of a flasher 18 increases as the supply voltage 15 increases, however as shown the relay 14 is energized by the initial peak current required by the lamps when the switch 28 is closed. The relay contacts 20 close and shunt the flasher 18 until the peak load current has fallen to a more steady value (Fig. 2, not shown), when the contacts 20 open and the expansible wire of the flasher starts to be heated. After expansion of the wire the flasher interrupts the supply to the lamp 30 and the above operation is repeated. By suitably adjusting the contact gap 20 and the spring 22 the currents required to open and close the relay contacts 20 can be adjusted to values so as to compensate for supply voltage variations to maintain the ON time of the lamp 30 constant. The circuit may be used in a direction-indicating arrangement of a vehicle. Construction of flasher.-The flasher may be as disclosed in Specification 1,181,474 which has a snap-action spring blade 10 (Figs. 7 and 9) with a pull ribbon 24 under tension. When current is supplied to the ribbon 24 via fixed contact 32, movable contact 26 on the ribbon and the blade 10 and a fixed contact 34 the ribbon expands and allows the blade to obtain an equilibrium position (Fig. 8, not shown). The blade then snaps to the position shown in Fig. 9 where the contacts 26 and 32 are open and the blade 10 then rests on an adjustable stop 42. Also in this position the ribbon 24 passes through a slot (20, Fig. 4, not shown), in the blade and is prevented from going too far by a tongue (22) cut out from the slot (20) and by the stop 42. Adjustment of the stop 42 controls the rate of flash. The blade may be of steel.

The radiation having a dominant wavelength in the range 380-420 mÁ can be obtained from conventional medium- or high-pressure mercury lamps which have been modified by inclusion of a metal selected from Ga, Pb, Al, Ca, Ce, In, K, La, Mg, Mn, Mo, Nb, Sc, Sr and Th, or a compound of such a metal, e.g. an iodide. The filter, where used, may be a silicate glass, e.g. soda-lime, lead, borosilicate, barium or alumina silicate glass, or a borate glass, e.g. alumina borate glass. The photocurable composition suitably comprises as the curable component an unsaturated polyester, unsaturated polyurethane, unsaturated acrylic, unsaturated alkyd or unsaturated epoxy resin. Examples of the photosensitizer are benzoin, benzoin ethers, benzophenone, benzil, 2,4-dichlorobenzaldehyde and disulphides. The photocuring process is of particular application in the curing of coloured coatings and, in addition to a colourant, the compositions may include such components as polymerizable monomers, solvents, fillers, &c. In the examples, the photocurable compositions are based on urethane-acrylate resins; polyesters modified by reaction with glycidyl methacrylate or a urethane-acrylate to introduce unsaturation; and acrylic resins modified by esterification to introduce unsaturation. In some cases the resins are used together with monomers selected from methyl methacrylate, trimethylolpropane trimethacrylate, cyclohexyl methacrylate, triallyl isocyanurate and styrene.
