Title: Improvements in grinding or abrading machines
IPC: B24B47/16
Filed: 1929-07-19
Abstract: 337,003. Triggs, W. W., (Norton Co.). July 19, 1929. Disc apparatus.-A grinding-machine comprises grinding-wheels 18 and 19 mounted on a spindle 13 which is capable of continuous axial reciprocation during grinding or of axial movement to a predetermined position in which it is held during grinding, means being also provided for the automatic withdrawal of the grinding-wheels at the completion of the operation. A worm 30 on the spindle engaging a worm wheel 31 imparts, through a cam 35, reciprocatory movement to a resiliently held follower 36 and an arm 37. Inward movement of a handle 60, Fig. 2, causes clutch teeth 56 to engage the arm 37 with a yoked lever 45, shoes 46 on which enter an annular groove 51 on the spindle and hence impart axial reciprocation thereto. If it is desired to bring the wheel repeatedly to the same position, the clutch is disengaged and a lever 70, Fig. 4, operated to rotate a gear segment 77 and, through a pinion 78, a cam 80, which bears on the yoked arm 45 and brings the grinding-wheel to a definite position, predetermined by adjustable set screws, the same being of such a shape that the wheels are definitely held in position. A cam 105 is adjusted in timed relationship with the feed screw so that reversal of the feed at the end of the cut is adapted to rotate the cam and cause a valve piston 109 to admit compressed air &c. through tubes 115 and 118 into a cylinder 120, Fig. 1, which, through a connecting rod 98, operates the gear segment 77 and releases the wheels axially.

The heaters B connected to headers D, DA are supported by angles g and bearers G, and are connected to each other by connectors E and welded joints F. Certain heaters are provided with cross through tubes H carrying nozzles H<2> with radial apertures, the passages at these points being enlarged. The nozzle heaters are disposed in horizontal rows, each row having separate supply pipes I controlled by valve I<2> from a common supply pipe I<3>. By this means, the whole internal surface of the heater may be effectually cleaned, or, if desired, any portion, so that the heating effect by the heater may be controlled. The nozzles may be detachable from the cross tubes H, and the tubes H may be integral with the heaters B. In a modification, the jets may be arranged pointing downwards from a projection on the heater block, Fig. 9, an annular groove B<6> connecting with the supply; or the supply pipes may be arranged between the rows of heaters, the projection having the jets being displaced laterally to allow of this. A hollow block may surround the connectors E and be provided with an annular groove to supply the jets. In a furthelr modification, the pressure of the cleaning fluid may advance jets from hollows in the heaters during cleaning, these being spring retracted after cleaning, or a reversing valve K, Fig. 18, may be installed to cause the jets to he power retracted. The cleaning fluid may be supplied from the superheater, in which case a weight operated plug valve H<14> is used normally to close the entrance to the jet HE, Fig. 20. The cleaning device may be installed in an ordinary radiation receiving face for a boiler. Sometimes steel heating tubes are protected by cast metal sleeves; in such cases annular chambered blocks HC<10> are used to convey the cleaning fluid to the jets, Fig. 23.

Abstract: 361,839. Glass manufacture. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST-GOBAIN, CHAUNY, ET CIREY, 1 bis, Place des Saussaies, Paris, France.-(Assignees of Pond, L. N. ; 1013, Wateree Road, Kingsport, Tennessee, U.S.A.) July 24, 1930, No. 22298. Convention date, July 25, 1929. [Class 56.] Rolling.-Relates to the method of making plate glass in which a quantity of molten glass is poured on to the receiving table of a double-roll machine in contact with the upper roll. The invention consists in giving to this roll, prior to the pouring of the glass on to the table, an initial distortion or warp which is opposite and substantially equal to the distortion caused by the hot glass. The two distortions neutralize one another and the rolls form a glass sheet of even thickness. The Figure shows a machine for making wire glass by rolling two sheets of glass E,by separate pairs of forming-rollers A, B, and consolidating the two sheets into a single sheet by another pair of rollers F, wire mesh E<1> being fed between the sheets as they pass between the rollers F. Water is circulated through the rolls A to cool them, and before molten glass is poured on to the receiving tables D, the rotation of the rolls is stopped. The water cools the lower parts of the rolls more than the upper parts, and this unequal cooling causes the rolls to bend slightly, the amount of warping being indicated by gauges K. The rolls are then rotated and when the parts most chilled are in position where they will be in contact with the hot glass, as indicated by the gauges K, the glass is dumped on to the tables D.

Title: Improvements in eddy current dynamometers
IPC: H02P29/00
Filed: 1939-08-02
Abstract: 531,787. Dynamometers. HEENAN & FROUDE, Ltd., and ROSS, E. G. Aug. 2, 1939, No. 22368. [Class 106 (ii)] A machine of the eddycurrent type employing a cylindrical rotor has arranged in its magnetic system a supplementary coil or coils excited from the variation of magnetic flux within the dynamometer. The magnetic system 1 of the machine is excited by a coil 2. The supplementary coil 3 is situated within the magnetic system and is preferably intimately wound with the coil 2. A coil 4 external to the magnetic system is in series with the coil 3 and intimately wound with a coil 5 in series with the field coil 2. The coils 4 and 5 form a mutually inductive system external tc the magnetic system of the dynamometer. Any change ir the magnetic system 1 will cause a variation of voltage in the coil 2 and a voltage is similarly generated in the coil 3 of the same sign of rate of change of variation. This causes changes in the coil 4 which induces changes in coil 5 of opposite sign and this opposes the change in the coil 2. Thus the variations in flux in the magnetic system 1 due to flux/speed conditions in the air-gap as the operational control is varied are automatically compensated for and instantaneous control of the speed and load of the machine made possible. The time effect of the coil system 4 and 5 may be fixed in some definite relationship to the systems 1, 2, 3 and this may be done by arranging a magnetic core to interlink the flux of coils 4 and 5 and this core in another form may be adjustable by means of a screw. Specification 524,080 is referred to.

Title: Improvements in and relating to engine fuels
IPC: C10L1/30
Filed: 1949-08-31
Abstract: A minor proportion of an organic nitroso compound of the general formula <FORM:0685764/III/1> wherein R1 and R2 are organic radicals other than aryl radicals, or wherein R1 and R2 together with the nitrogen atom to which they are attached form an organic heterocyclic ring, is added to a gasoline hydrocarbon of boiling point range about 100 DEG  to 400 DEG F.  Such fuel eliminates, or materially reduces, the combustion chamber deposits.  R1 may be an alkyl, alkenyl, aralkyl, alicyclic, cyclo-olefinic or a heterocyclic radical such as methyl, ethyl, propyl, isopropyl, normal butyl, secondary butyl, tertiary butyl, hexyl, iso-octyl, dodecyl, cetyl, stearyl, trimethyl octadecyl, allyl, methallyl, crotyl, deyl, cyclopentyl, methyl cyclopentyl, cyclohexyl, isopropyl cyclohexyl, endomethylene cyclohexyl, cyclopentenyl, cyclohexenyl, pyridyl, pyrrolyl and the tetramethylene sulphone radical.  R2 may be any of the above radicals, being the same or different from R1.  The organic radicals may be substituted by halogen atoms, amino or nitro groups.  Suitably the number of carbon atoms in R1 and R2 together is from 5 to 40, and preferably from 6 to 20.  The preferred compound is dicyclohexyl nitrosamine: others are diisopropyl nitrosamine, di-n-butyl nitrosamine, di-n-propyl nitrosamine, diisobutyl nitrosamine, methylpentyl nitrosamine, methylcyclohexyl nitrosamine, bis (3:3:5-trimethyl-cyclohexyl) nitrosamine, N-nitroso-2:4:4:6-tetramethyl tetrahydro-1:3-oxazine, methyl benzylnitrosamine, 1:4-dinitroso piperazine, allyl butyl nitrosamine, n-propylcyclohexenyl nitrosamine and N-nitroso-morpholine.  Two or more nitroso additives may be used together if desired.  The amount used may be between about 0.001 per cent and about 1 per cent (preferably within the range about 0.01 per cent to 0.3 per cent) by weight, based on the mixture of gasoline hydrocarbons.  Emulsifying agents such as triethanolamine oleate or alkali metal sulphonates, oxidation inhibitors such as alpha-naphthol and solutizers may be employed if desired.  The addition of nitrosamines containing a substituent ether group or a sulphur, selenium or tellurium analogue of such group to p  gasoline is disclaimed.  In an example dicyclohexyl nitrosamine was dissolved in an 80 octane member leaded gasoline to form a 0.02 per cent solution by weight, and the fuel burned in an aircraft engine.  After 50 hours running, no spark plug fouling was observed, and the amount of piston and combustion chamber deposits was greatly decreased.  The Specification as open to inspection under Sect. 91, comprises also the use of nitrosamines in which the radicals R1 and R2 may be aryl radicles, such as diphenyl nitrosamine.  This subject-matter does not appear in the Specification as accepted.
