Abstract: 508,906. Sealing. MOSEY, F. W., and SEAL-LESS STRAPPING, Ltd. May 18, 1938, No. 14872. [Class 146 (ii)] In sealing the overlapping ends of metal bands by cutting therein one or more pairs of zigzag slits and deforming the endless tongues so formed, as described in Specifications 267,160, [Class 94 (i)], and 417,821, [Group XXII], the free end of the band is sheared and bent downwardly to form a continuation of one of the deformed tongues. The band is tensioned by known mechanism, and the slits are cut by relatively-movable die-members 10, 12 which are preferably formed with co-operating V-shaped projections and recesses 25, 26 to produce corrugations extending transversely across the slit portions. The upper movable die 12 carries a cutter 13 having a wide, substantially U-shaped cutting-edge 17 and a part 19 inclined upwardly from the edge. The edge 17 co-operates with a fixed anvil 15 to sever the free end of the band, and the part 19 forces the cut end into a depression 21, 22 in a block 20 attached to the lower die 10. The die-members may be so shaped as to form convergent slits at one end of the tongues. Means similar to those described in Specification 493,081 are provided for releasing the sealed ends from the diemember 10.

Abstract: 361,382. Motor vehicle driving-gearing. WIEDMAIER, A. A., 1838, East 90th, Street, Cleveland, Ohio, U.S.A. May 17, 1930, No. 15254. [Class 79 (ii).] Rear axle driving gear for motor vehicles comprises a bevel differential train combined with an epicyclic train giving a solid or a high-speed drive, an internally toothed wheel 47 in the epicyclic train being integral with or secured to the spider 33 of the differential gear. Driving effort is applied to the planet-carrier 10 which is bolted to a bevel wheel 20 engaging a driving pinion 21. For solid drive the planet-carrier is clutched to a sun wheel 49 free on the axle shaft 19, by operating, from the driver's seat, a sliding clutch member 53 splined on the boss of the sun wheel 49 and having peripheral teeth 55 engaging facial teeth 57 on the boss of the planet-carrier 10. For the high-speed drive the sun wheel 49 is held stationary by engaging the clutch member with internal teeth 56 on a casing member 9. The planet pinions are mounted on hollow bushes 26 supported between the carrier 10 and an inner plate 25 attached by three press-fitted pins 24 to the carrier. The plate 25 has an inner boss, bearing in the sun wheel 49 and on the boss of the differential bevel pinion 31 so as to transmit the supporting effect of the roller bearing to the bevel pinion and to the differential spider 33, the latter through a flange 43 integral with the spider. The planet-carrier 10 also carries a member 16 supported in the right hand bearing and forming with the planetcarrier a rigid housing for the gear. The sun wheel 49 is located axially by the. plate 25 and the differential pinions are maintained in mesh by the side flanges against which they bear. The outer races of the bearings are adjusted by screwthreaded members 8, 9. In a modification, also shown, the epicyclic train is at the side of the differential train remote from the driving bevel 20 and the housing 10 .. 16 is in three parts, one of which carries integral pins on which the planet pinions are mounted. A ball bearing is provided between the planet-carrier and the boss of the sun wheel and between the planet-carrier and the casing. The internally toothed wheel 47 is integral with the differential spider, and the differential bevel wheels 31, 37 are integral with the axle shafts instead of being splined thereto.

Class 123(1) [Also in Group XXV] An opening 3, occupying almost one entire side of a fan casing 2 located beneath a winch motor housing 1, is closable in a watertight manner by means of a cover 4 which is pivoted to the housing by straps 25. A spindle 9, rotatably mounted in a bushing 13 in the cover 4, carries an outer handwheel 6 and a pin 14 on its inner end which is journalled in a bearing plate 15 carried by a plate 16 which is cut away in the region of the spindle 9 and is secured to the cover 4 in a vertical plane passing through the spindle axis. The spindle 9 is externally screw-threaded adjacent the bearing plate 15 for co-operation with a nut 10 which has two opposed parallel flats 11, 12 spaced by a distance slightly less than that existing between two parallel plates 17, 18 which are located one on each side of the plate 16 and are carried by the fan casing 2. Vertically offset openings 79, 20 are formed respectively in the plates 18, 17 in the region of the nut 10. In the position shown in Fig. 1 the flats 11, 12 on the nut 10 are parallel with the inner faces of the plates 17, 18 so that the cover can be opened. From the position, Fig. 1, the door can, be tightly sealed in the opening 2 by rotating the spindle 9 in a clockwise direction until the flats 11, 12 on the nut, which is rotated with the spindle, engage lower and upper abutment faces 21, 22 of the openings 20, 19 respectively. Upon further rotation of the handwheel 6 in the same direction the nut 10 travels axially and then tightens against the vertical edges 23, 24 of the openings 20, 19 as the cover 4 becomes tightly sealed in the opening 2. Anticlockwise rotation of the handwheel 6 causes the nut 10 to loosen and then to rotate with the spindle 9 until it abuts the surfaces 28, 29. The cover 4, with the spindle 9 and the nut 10, can then be swung outwardly until an extension 26 of the end plate 15 contacts an abutment'27 on the casing.

Title: Improvements in or relating to the production of alloys for permanent magnets
IPC: C22C9/06
Filed: 1937-06-03
Abstract: The magnetic properties of copper-nickel-iron alloys containing more than 50 per cent of copper nickel for use as permanent magnets are improved by cold rolling the alloys to a degree which reduces their cross-section by more than 40 per cent, and preferably more than 70 per cent, and then heat-treating the rolled alloys at 500-750 DEG  C. The alloys may be subjected to a preliminary shaping with or without an incandescent heating and quenching prior to the cold rolling.  The alloys may be annealed at 500-700 DEG  C. preferably after the quenching and before the cold rolling and may contain also up to 5 per cent of cobalt and up to 2 per cent of beryllium.  As applied to an alloy containing 15-25 per cent of nickel, 10-25 of iron and 50-75 of copper, the alloy is subjected to an incandescent heating above 1000 DEG  C., quenched, annealed at 500-700 DEG  C., cold rolled and finally annealed at 500-700 DEG  C.  In a particular example an alloy containing 20 per cent of nickel, 20 of iron and 60 of copper was cast in bars 43 mm. thick and then rolled down to 23 mm. diameter. The bars were then heated at 1050 DEG  C. for 10 hours, rolled down to a diameter of 10,7 mm., annealed for one hour at 600 DEG  C. and cooled in air.

Abstract: The invention comprises as new compounds sultam-N-phosphoric (and -thiosphoric) acid diesters of the general formula <FORM:0761913/IV(b)/1> in which R is a saturated straight or branched chain aliphatic hydrocarbon radical containing from 3 to 6 carbon atoms, R1 is a methyl or ethyl group and X is an oxygen or sulphur atom. They may be prepared by reacting, in the presence of an inert solvent, an alkali metal salt of a sultam having the formula <FORM:0761913/IV(b)/2> in which Me is an alkali metal with the appropriate chlorophosphoric acid diester or chlorothiophosphoric acid diester.  The reaction may be carried out by suspending the alkali metal sultam in the inert solvent, e.g. benzene, ether, or dioxane, and mixing with an equivalent amount of chlorophosphoric acid diester while stirring and the reaction temperature may range from between 20 DEG  and 80 DEG C.  Specified sultams are g -propane sultam, d -butane sultam and a -methyl-g -propane sultam.  In examples: (1) a -methyl-g -propane sultam is added to a solution of sodium methoxide in methanol to form the sodium sultam which is then suspended in benzene, the mixture heated to 50 DEG C. and chlorophosphoric acid diethyl ester added slowly to form the sultam-N-phosphoric acid diethyl ester; (2) chlorophosphoric acid diethyl ester is added slowly at 35 DEG C. to a stirred suspension of N-sodium-d -butane sultam in benzene to form d -butane sultam-N-phosphoric acid diethyl ester.  The products may be used as pesticides.  The sultams may be obtained from aminoalkane sulphochloride hydrochlorides by treating with alkali, from chloroalkane sulphonamides by heating, or by the action of ammonia on oxyalkane sulphonic acids and may be converted into their alkali metal salts by reacting an equivalent amount of an alkali metal alcoholate on a solution of the sultam in an alcohol.
