IPC: B41B1/00
Filed: 1956-04-19
Abstract: 789,053. Printers' composing-appliances. HALL, J. A. May 2, 1956 [April 19, 1956], No. 11881/56. Class 100(3) Scales. A device for calculating the length of a line of type and the number of lines of type a manuscript will occupy when set comprises a sheet on which is set out rows of figures each representing a fount of type, the terminal figure of each row representing the width in 12 point ems of 100 characters, the figures in the top row representing the number of characters, and the figures in the other rows representing the width of the corresponding founts of lines having the number of characters indicated by the figure in the top row vertically above, together with a vertical slide bearing the names and sizes of the founts corresponding to the rows over which the slide moves horizontally. The slide comprises two pieces of opaque plastic separated by distance pieces to form a sleeve and having an aperture. A piece of transparent plastic is fixed by distans pieces to both opaque pieces, leaving a space into which can be inserted slips of paper bearing the names and sizes of the founts. The sheet is provided with twenty rows of figures on each side, the top row on each side having equally spaced figures 1-100, and. the terminal numbers of the remaining 38 rows being 25. 25¢, 26, 26¢ &c. to 34¢, 35 and thence 36, 37, &c. to 54. In the case of the rows ending in whole numbers the figures are from 1 to the terminal number substantially evenly spaced, and in the case of the rows ending in fractions, the figures are from 1 to the whole number below the fraction substantially evenly spaced, followed by a shorter snace before the terminal fraction. The even spacing between the figures is modified by each figure being placed vertically below the figure in the top row nearest to its evenly-spaced position. To calculate the number of lines of type a manuscript will occupy when set divide the number of characters in the manuscript by the measure in 12 point ems to which it is to be set, and move the slide into line with the quotient in the top row, a vertical reading down the slide giving the number of lines occupied when set in type having equal widths per 100 characters to the terminal numbers in the rows.

Title: Improvements in apparatus for heating air and/or other gases
IPC: F28D7/00
Filed: 1926-05-06
Abstract: 275,706. Fahrenwald, F. A., and Smith, H. E. May 6, 1926. Hot-blast stores.-A continuous heat exchange apparatus adapted to be fitted in the casings of existing regenerative hot-blast stoves &c. comprises vertically disposed conduits of heat conducting material suspended in a chamber with their lower ends free to expand and contract, means for causing hot gases to flow upwardly through the chamber and means for supplying the cold air or gas to the lower ends of the conduits. The casing 1 is divided by a concentric chimney 4 into a central up-draught chamber 6 and an annular down-draught chamber 5, a burner 7 being arranged at the base of the chamber 6 and the hot gases escaping through passages 12 to an annular flue 11 communicating with an exhaust fan 13 which discharges into the stack 14. An arch 24 near the top of the furnace supports a manifold 15 from which depend pipes 20, 21 passing through the chambers 5, 6 respectively and connected to lower manifolds 26 27 each supplied with the air or gas to be heated by a fan 29. The manifold 15, pipes 21 and at least the upper ends of the pipes 20 are made of a heat resisting alloy containing chromium. From the manifold 15 a branched pipe 16 leads to an outlet conduit 17 for the heated gas. The lower ends of the pipes 20, 21 may take within annular pcckets 31, Fig. 6, containing mercury or other sealing liquid to allow for expansion, or a sliding joint sealed by soft packing may be arranged between the lower ends of the pipes and the manifolds 26, 27. In further modifications the manifolds are fixed rigidly to the pipes and entirely supported thereby so that they are free to rise and fall as the pipes contract and expand, or the manifolds are supported from below and connected to the pipes by flexible hose. Arches 36 separate the lower ends of the pipes and the manifolds 26, 27 from the heating chamber and cold air may be forced into the chamber below these arches. Recuperator units 40, 41 of thin sheet iron may be arranged in the stack 14 and supplied with air at 42. Gas is supplied to the burner by a pipe 8 and preheated air by a pipe 9 connected with a blower 10. The upper manifold may be supported on the upper end of the chimney 4 and may comprise a central part from which depend the pipes 21 and radiating arms from which depend the pipes 20; in this form the chimney 4 is formed with lateral openings near the top for the outlet of the hot gases. The hot gas inlet passage may be arranged laterally above the manifolds 26, 27 and the lower end of the chimney 4 formed with arched openings affording communication between all parts of the bottom of the stove, to which cooling air may be supplied. The discharge conduit 17 may be replaced by outlet pipes for the heated gas arranged within vertical passages extending through the walls of the chimney 4 or through a central channel separated from the heating chamher by a firebrick wall.

Filed: 1919-05-12
Abstract: 1 - Oxynaphthalene sulphocarboxylic acids, having a free 2-position, are prepared by alkali fusion from naphthalene disulphocarboxylic acids having a sulpho group in 1-position. According to examples: - 2 - naphthylamine - 5 : 7 - disulphonic acid is converted into 2 - cyanonaphthalene - 5 : 7 - disulphonic acid, which is saponified to naphthalene - 5 : 7 - disulpho - 2 - carboxylic acid, from which, on alkali fusion, 1 - oxynaphthalene - 3 - sulpho - 6 - carboxylic acid results; 1 - oxynaphthalene - 3 - sulpho - 5 - carboxylic acid is prepared similarly, starting from 1 - naphthylamine - 5 : 7 - disulphonic acid.  Monoazo dyes are prepared by coupling aromatic o-oxydiazo compounds with the 1-oxynaphthalene sulphocarboxylic acids described above.  The products are mordant dyes and may be dyed on wool with chrome mordants or printed on chrome-mordanted cotton.  The mordant character of the dyes may be enhanced by using as the diazo component o-oxydiazo compounds derived from salicylic acid. According to examples, products are obtained from the following pairs of components: - 4 - nitro - 2 - amino - 1 - oxybenzene - 6 - carboxylic acid and 1 - oxynaphthalene - 3 - sulpho-6-carboxylic acid; 4 - sulpho - 2 - amino - 1 - oxybenzene - 6 - carboxylic acid and 1 - oxynaphthalene - 3 - sulpho - 6 - carboxylic acid or 1 - oxynaphthalene - 3 - sulpho - 5 - carboxylic acid; 4 - chlor - 2-amino - 1 - oxybenzene - 6 - carboxylic acid and 1 - oxynaphthalene - 3 - sulpho - 5 - carboxylic acid; these products give bordeaux, red-violet, and violet shades respectively on wool or cotton with chrome mordants.

Title: Improvements in plants for preparing peeled-off veneers
IPC: B27L5/00
Filed: 1960-04-06
Abstract: 910,175. Cutting wood. MULLER, C. H. April 6, 1960 [April 15, 1959], No. 12145/60. Class 145. Veneers peeled from a tree trunk by a peeling machine 1, Fig. 1, are transported to further treatment machines 17, 3, e.g. shearing- machines, by superposed conveying means 25, 16 arranged respectively to receive the initially peeled-off pieces and strips and a suspended truck 2 on which the subsequent continuous peeled-off strip is wound for delivery to a magazine. The pieces of veneer initially cut from the uneven surface of a tree trunk are fed down a pivoted transfer bridge 21 and piled on to a truck 26 which, when fully loaded, runs along a track 25 on to a platform 18 arranged to be slowly raised to bring the uppermost pieces successively into a position in which they can be pushed into the shearing machine 17. When the truck is empty it is moved along the superposed track 24 and returned to the loading position down a movable ramp 24a. Strips of veneer which are then peeled off are fed over the then-raised bridge 21 along a roller track or band 16 to the shearing-machine 17. Following the peeling of the pieces and strips a continuous veneer strip is obtained and wound on to a roller 4 which is mounted in the truck 2 and driven by a motor 3, the truck then being so positioned on its rails 6 by a motor 5 as to be opposite the delivery from the peeling-machine. When the roll 4 is fully wound, the truck is moved on the rails 6 into position opposite a magazine 7, Fig. 2, where the roll is transferred by a platform 8, Fig. 1, on to tracks 9. The rolls pass along these tracks to a lift 11 which raises successive rolls to a position from which the veneer bands are unwound by a motor 12 and transferred to the shearing-machine S. The empty rolls run back along an upper track 13 to a position in which a device 14 feeds them back to the truck 2. Since a truck 26 remains at the receiving station while several trunks are being peeled and at such station tends to interfere with the winding of a band on the roller 4, a motor 55, Fig. 1, is provided for withdrawing the truck slightly from receiving position whenever the band is being wound and then returning it. The motor is arranged to act through a spring hook coupling 51 which is automatically connected with the truck whenever the latter is in the region of the receiving station and automatically released when the truck, fully loaded, is advanced along the track 25 to the lifting platform 18.

Title: An improved short period press button switch
IPC: H01H43/30
Filed: 1943-07-27
Abstract: 564,962. Electrically-released switches. LANDIS & GYR SOC. ANON. July 27, 1943, No. 12239. Convention date, Aug. 13, 1942. [Class 38 (v)] A thermally - retarded, short - time, pressbutton switch, of configuration generally similar to existing wall-switches, has a contact spring 4 adapted to be depressed by the button 3 so that its free end 6 engages under a shoulder 11 on a pivoted spring-catch 8 insulated at 7 from the bimetal strip 1. A heating coil 13 connected between the catch 8 and the fixing screw 2 of the strip 1 is thus energized in series in the main circuit flexing the strip until an adjustable insulating stop 9 thereon deflects the latch 8, but the end 6, in rising, engages under a projection 10 on the strip, so making a direct circuit to screw 2 through the strip (or a special conductor). The byepassed strip accordingly cools and 10 moves clear of 6 and opens the circuit. In the open position, an insulating piece 16 under spring 6 holds catch 8 out of contact, and may extend beyond the edge of spring 6 to prevent closure of the switch by prolonged depression of button 3. The contactprojection 10 may be replaced by a latch not carried by element 1, but tripable by the element to disengage it from spring 6.

[Class 82 (i)] [Also in Groups V and XXII] Steels and steel alloys are made by pressing and sintering, in a non-oxidizing atmosphere at above the critical temperature at which the structure is austenitic, a mass of powdered iron containing iron carbide. The mass may be in the form of a mixture of powdered iron and powdered iron carbide, or a mixture of powdered iron and powdered ferro-alloy, preferably ferrochrome, containing iron carbide, or particles of iron which have been carburized on the surface, for example by treatment in propane. The iron carbide or the alloy containing it is preferably free from uncombined carbon. Other elements including nickel, manganese, vanadium, tungsten, silicon, phosphorus, and sulphur may also be present. The sintered product may be quenched, hardened and tempered. For the production, for example, of tool steels, the proportion of iron carbide to pure iron powder may be 5-20 per cent. For making porous products, for example, bearings, a material such as petroleum oil, salicylic acid, ammonium chloride, mica, talc, a carbonate or bicarbonate, or a solution of stearic acid may be added to the mixture, and graphite may be added to improve the bearing properties. Composite articles may be made either by using powders of different compositions in different parts, or by the use of a solid core such as of mild steel.

Title: Improvements in or relating to the treatment of silicon
IPC: H01L21/00
Filed: 1943-07-28
Abstract: <PICT:0590458/III/1> Silicon having enhanced asymmetrical electric conductivity is obtained by heating silicon containing not more than 1 per cent. impurities to a temperature above its fusion temperature, and controlling the cooling of the fused material so that solidification commences at one point, plane, or zone of the molten material and proceeds in a slow and orderly manner throughout the remainder of the molten mass.  According to a p  modification, carbon in the proportion of about 0.1 per cent. or silicon carbide in the proportion of about 0.1 to 0.5 per cent. is added to the initial silicon.  The cooling may be controlled so that its rate from about 200 DEG C. above the fusion temperature down to 1100 DEG C. is less than 200 DEG C. per minute.  Such control may be effected by a gradual reduction of applied heat and by providing increased thermal insulation around part of the molten mass, for insance the lower part of the mass, so that solidification commences at the top of the melt and proceeds regularly downwards. The fusion may be effected in an atmosphere of helium, nitrogen, hydrogen or air, or in vacuo the material being placed in a silica crucible.  The process may be conducted in an electric induction furnace as shown in Fig. 2 in which a silica crucible 25 containing the charge is held in position within a graphite crucible 27 by means of a bed 28 of silica powder. The crucible 27 has a silica cover 31 provided with an observation opening 32 and is seated upon a second bed 29 of silica powder in which an alundum cylinder 30 is thrust sufficiently far to ensure it being firmly positioned for supporting the crucible 27.  An outer silica tube 33 of the furnace is surrounded by a heating coil 11 carrying high frequency alternating current.  The cover 12 of the furnace is provided with an inspection window 36 and ducts for applying vacuum and introducing gases.  U.S.A. Specification 1,386,227 is referred to.
