Title: Process for the preparation of new dyestuff derivatives
IPC: C09B62/04
Filed: 1960-06-28
Abstract: In a process for the manufacture of new dyestuff according to the parent Specification, a water-soluble organic dyestuff of the specified kind which contains a residue of the formula <FORM:0902787/IV(a)/1> in which A represents a hydrogen atom, an alkylol group or an etherified alkylol group, and B represents an -HN-A group (where A has the above meaning), an etherified hydroxyl group or a halogen atom is reacted with the components of a mixture giving rise to a restrictedly water-soluble precondensate, either singly or in combination or in a series of combinations, and consisting of urea or an aminotriazine, formaldehyde, and an aliphatic alcohol containing 3 to 7 carbon atoms.  The product can be applied as an aqueous dispersion, with a polyglycol derivative of a higher amine or alcohol, to textile materials.  In a typical example (1) there are reacted formaldehyde, melamine, and a dyestuff of the formula <FORM:0902787/IV(a)/2> at pH to 8,5 and the product when it remains clear on cooling, is reacted with butanol.  In other examples are used an anthroquinone dyestuff, a substituted copper phthalocyanine and a coppered azo dyestuff, respectively, in generally similar processes.ALSO:Textile materials are treated with a dyestuff prepared by reacting a water soluble dyestuff that contains at least one substituent capable of reacting with alkylol groups and residue of the formula <FORM:0902787/IV (b)/1> in which A represents a hydrogen atom, an alkylol group or an etherified alkylol group, and B represents an -HN-A group, an etherified hydroxyl group or a halogen atom, with the components of a mixture giving rise to a restrictedly water-soluble precondensate and consisting of urea or an aminotriazine, formaldehyde and an aliphatic alcohol containing 3 to 7 carbon atoms.  The products can be applied by impregnation or as printing pastes.  In a typical example (1) there are reacted formaldehyde, melamine and a dyestuff of the formula <FORM:0902787/IV (b)/2> at pH 8 to 8.5, and the product, when it remains clear on cooling, is reacted with butanol.  Further butanol is added followed by an aqueous solution of a hydroabietyl alcohol/ethylene oxide reaction product cross-linked with hexamethylene diisocyanate.  The resulting suspension, to which further water and zinc nitrate are added is used to pad mercerised cotton.  After drying and hardening of the resin the product can be further treated with an aqueous solution of sodium 2-heptadecyl-N-benzyl - benzimidazole disulphonate and sodium carbonate.  Generally similar processes are described in which an anthraquinone dyestuff, a substituted copper phthalocyanine and a coppered azo dyestuff are used.

IPC: B23K35/38
Filed: 1930-07-28
Abstract: Carbonyl compounds of metals such as iron, nickel, uranium, vanadium, chromium, and the like are used in fusion welding to provide an atmosphere of carbon monoxide to prevent access of atmospheric oxygen.  For welding iron or iron alloys solid iron carbonyls such as nona-carbonyl or tetra-carbonyl may be used either alone or mixed with other solid carbonyls or formed into a paste with the penta or other liquid iron carbonyl.  For welding nickel or nickel alloys nickel carbonyl may be mixed with solid and/or liquid iron carbonyls. The carbonyl compounds may also be mixed with other welding agents such as fluxes or mixtures of oxides.  Thus 5 or 3 parts of anhydrous borax may be mixed with 3 or 2 parts of a liquid iron carbonyl or with the same or slightly increased proportion of a solid carbonyl. The Specification as open to inspection under Sect. 91 (3) (a) states that cobalt carbonyl may also be used and that solid carbonyls may be formed into a paste with organic substances such as hydrocarbons, higher alcohols or fatty, wax-like or resinous substances.  This subject-matter does not appear in the Specification as accepted.

Title: Method of producing vitreous clay products
IPC: C03C11/00
Filed: 1962-06-13
Abstract: <PICT:0952569/C1/1> <PICT:0952569/C1/2> In the production of porous glass from clays either containing or with added gaseous material the raw clay is heated to a bloated condition below the temperature of fusion, passed into a mould which is at a temperature below the fusion temperature and pressed in the mould with the gases confined therein until converted into a fused condition. The raw material, which may just be reduced to uniform particle size, is fed from a hopper 13 to a rotary kiln 15 heated by a burner 18 with an auxiliary burner 20 to maintain the temperature of the bloated mixture at the discharge end of the kiln.  The mixture is discharged to a mould 22 of metal, which may be additionally cooled by circulating air, the mould 22 being of elongate rectangular form partially enclosed by a plate 30 with a cutting edge 31. The one end 25 is removably mounted for displacement along tracks 26 and is held by pins 34 on lugs 35 until a predetermined pressure releases the pins.  At the other end a power-operated ram 28 moves the material deposited in the open section 32 of the mould to seal the material below the plate 30 and compress the material until fused.  A number of suitable clay compositions are given together with gas producing additions when necessary.

Title: Improvements in gear cutting machines
IPC: B23F5/16
Filed: 1932-08-12
Abstract: 399,001. Gear-cutting. SCHMITT, W., 5, Bismarckstrasse, Ettlingen, Baden, Germany. Aug. 12, 1932, No. 22681. Convention date, Aug. 29,1931. [Class 83 (iii).] In a gear-cutting machine of the reciprocating pinion-cutter type, the depth feed between the cutter and the work is produced by a cam which is rotated by mechanism dependent upon the reciprocation of the cutter, and after the full depth is attained, the cam is driven by separate mechanism which is actuated in dependence upon the rotation of the work while the tool is maintained at its full working depth. The cutter 26 mounted on a spindle 25 is reciprocated from a crank disc acting through a link 23, and toothed lever 24. The main shaft 1 is also connected through bevel gearing 2, loose worm gearing 4, splined clutch 9 and worm gearing 6 to a spindle 27 carrying the feed cam 8 which through a roller 11 and rod 15 imparts feed movement to the slide 28 to feed the cutter into the work 36 which is rotated for the generating movement by worm gearing 34. When the cam 8 has rotated so far as to allow the lever 10 to drop as shown in the Figure, the full tooth depth is reached and a lever 29 is released whereupon a spring 30 disengages the clutch 9 and engages a clutch part 12. This clutch is driven by ratchet gearing 14, levers 16, 31 from an eccentric 32 on the spindle of the worm 34. When driven in this way the cam 8 is arranged to rotate through a quarter revolution while the work spindle makes a complete revolution, the full depth position of the slide 28 being maintained. On further movement of the cam, the roller 11 drops into a recess and the cutter slide is withdrawn by a spring 37. The roller 11 may be replaced by a block which allows a sudden withdrawal movement which may be utilized for stopping the machine. In a modification the depth feed may be applied to the work instead of the cutter. By changing the gearing 2 the rate of lateral feed may be altered independently of the work rotation.

Title: Improvements in or relating to the feeding of alternating current systems by asynchronous generators
IPC: H02K17/42
Filed: 1925-09-12
Abstract: 239,881. Siemens - Schuckertwerke Ges. Sept. 13, 1924, [Convention date]. Alternating - current induction machines.- An asychronous generator is made to supply energy at constant frequency independently of variations in its own speed by being excited through a cascaded, compensated commutator machine which acts as a frequency transformer between the induction generator and a supply circuit of which the voltage and frequency are independent of the circuit fed by the induction generator. In the form shown in Fig. 1, the asynchronous generator 1, which is driven by a motor 2 and feeds a system 5, is excited through its rotor by a mechanically coupled commutator machine 3 fed through its rotor from an independent constant frequency system 4. The frequency given by the machine 1 is independent of its speed. The machine 3 may be excited through its stator, as shown in Figs. 2 and 3, in which case it is arranged to give a variable frequency to correct changes in the speed of the asynchronous generator. In Fig. 2, the commutator machine 3 is stator-excited from a mechanically-coupled frequency converter 6 which is fed from constant frequency mains 4. In Fig. 3, the stator excitation of the machine 3 is derived from a so-called " electrical differential gear " comprising a synchronous type of machine of which the stator member 8 is mechanically coupled to the asynchronous generator group and the rotor is independently driven by a motor 7 and excited from a continuous current supply 9. It is shown in the Specification that with connections as described above the machine 1 has a compounding property at hyper-synchronous speeds whereby its voltage is kept up with increasing load, but independent regulating means of known type may be used for regulating the voltage or the wattless energy generated by the machine 1. When several asynchronous generators working in parallel are excited from separate sources, synchronizing conductors or mechanical arrangements may be employed for keeping the sources in synchronism, and means may be employed for distributing the load among the generators. Where several generators work in a common system, they are preferably arranged so that any one may act either as a " time giving " machine for the others or independently. For example, in an hydro-electric plant the exciting machine is arranged to be driven either by a water turbine at constant speed for time-marking or, alternatively, by a synchronous motor forming part of the system if the time marking is to be transferred to another member of the plant, the constant-speed turbine running light in these circumstances.

Title: Improvements in or relating to method of and apparatus for fusing and agglomerating fine particles of material
IPC: C22B1/216
Filed: 1949-09-06
Abstract: 679,639. Agglomerating ores; removing undesired constituents. GREAT LAKES STEEL CORPORATION. Sept. 6, 1949 [Sept. 17, 1948], No. 23058/49. Class 82(i) [Also in Group XII] Relatively fine particled material such as flue dust or fine iron ore is fused and agglomerated by passing it down through a preheat zone of a furnace in an inclined path, preheating it to a temperature below its fusion temperature, thereafter passing the material down through a fusion zone in a path parallel to the first-mentioned path and heating at least some of the particles to fusion temperature and agglomerating them to form larger particles, the path of travel through the fusion zone being below that in the preheat zone so that particles cascade down from the preheat zone to the fusion zone and are thoroughly mixed. In the apparatus shown in Fig. 1 fine material which may be mixed with fuel is delivered by shoot 30 to the upper end of a rotary preheat furnace 10 down. which it travels and in which undesirable constituents such as sulphur, lead or zinc are removed by volatilization. At the lower end of the preheat furnace the material cascades down shoot 43 into a rotary furnace 11 of larger diameter than the preheat furnace, e.g having an internal diameter at least twice at large. Additional fuel, if required, is supplied to the material by shoot 48 at or near the point of cascading and a blast of air from pipe 55, directed downwards on to the material in the fusion furnace, ensures heating of the material to its fusion point, the products of combustion passing up to the preheat zone mixed, if necessary, with additional air introduced by a pipe through the cover 42 which encloses the adjacent ends of the furnaces and prevents the escape of gases. A cover 44 closes the lower end of the fusion furnace and is provided with an opening 45 and shoot 46 for discharge of agglomerated material. The Specification as open to inspection under Sect. 91, comprises also apparatus in which the rotary preheat furnace and fusion furnace are concentric. This subjectmatter does not appearin the Specification as accepted.

Title: Indicators suitable for use with radio-direction finders and the like
IPC: G01S1/02
Filed: 1944-11-20
Abstract: 601,055. Radio direction-finding. SMITH, S. B. Nov. 20, 1944, No. 23084. [Class 40 (vii)] [Also in Group XIX] In an indicator the scale is normally invisible, and after a cursor or marker has been adjusted to the position of the indication the scale is rendered visible so that the reading may be determined by comparison of the cursor or marker and the scale. This enables a succession of readings to be taken, for the purpose of determining a mean, without bias due to the presence of the scale. In the application of the invention to a radio direction-finder of the type employing a continuously rotated goniometer, the indicator comprises a cathode-ray tube CRO with a sliding cursor Cu in front of the screen Sc. A hood H excludes external light and the scale S on the tube screen is normally invisible. The cursor Cu is adjusted by the handle CH in its normally OUT position, to the indicating point D of the trace on the screen and the handle CH is then depressed to the IN position, closing contacts S1 and S2 and the circuit for lamps L which thus floodlight'the screen and scale so that the position of the cursor may be read from the scale as in Fig. 1c. Depression of handle CH disengages the cursor driving mechanism and contacts S1, S2 may also be arranged to extinguish or dim the trace on the cathode-ray tube screen. Handle CH. when released may also be arranged to displace the cursor so that the previous setting is completely removed. If the direction finding system is of the type in which the position of a pattern or line on a cathode-ray tube is compared with a circular scale, the light-excluding hood may be arranged for rotation axially with respect to the tube to control the cursor and may be depressed bodily to disengage the cursor and operate the switch contacts, Fig. 2 (not shown).
