[Class 103 (vi)] The two or more wheels 1 on each side of a railway-vehicle bogie are mounted in separate frames 2, which are connected to the ends of the bolster 7 by joints 5 so as to be capable of pivotal movement both in an horizontal and in a vertical plane, rotational movement of the bolster relative to the vehicle body being prevented by a guide frame 9, Fig. 2, within which the ends of the bolster may move vertically or laterally. In the construction shown in Figs. 1-3, two wheels 1 are mounted in each frame, and the two frames 2 are inter-connected by gauge bars 11 having inserted springs 12 that permit a limited lateral freedom of motion between the frames. Between the body bolster 6 and the bogie bolster 7 are arranged a number of helical supporting springs 8, and, if desired, oscillation dampers. The joints 5 are preferably disposed within dust-tight casings 10 filled with oil. In a modification, four wheels are arranged on each side of the bogie, grouped in pairs, and each pair is carried in a small auxiliary frame pivotally and resiliently mounted in the frame 2. The Specification as open to inspection under Sect. 91 also described a modification in which the frames 2 are inclined inwardly. This subject-matter does not appear in the Specification as accepted.

Filed: 1948-05-21
Abstract: 638,738. Measuring bridges. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. May 21, 1948, No. 13825. [Class 37] A transmission line, e.g. a coaxial cable, terminated in its characteristic impedance is tested for reflection of any applied pulse from discontinuities along the line ; to this end, the line is connected to terminals 1 to form one arm of a balanced bridge, and pulses are applied across the input diagonal A.C., the output diagonal BD being connected to the grid and cathode of a valve 12 whose output is presented so as to indicate output variations with time, as by a cathode-ray oscillograph 15. The bridge is balanced by adjustment of the network 3 and capacity 2, resistance 8 being varied for fine adjustments ; the applied pulses from generator 9 are then of very small effect on the cathode-ray tube while reflected pulses, being applied across arm CD are revealed on the oscillograph 15, and the position of discontinuities may be determined by measurement of the distance between the traces due to the transmitted and reflected pulses. A resistance 11 matches the circuit to the line at terminals 1.

Filed: 1929-05-07
Abstract: 328,127. Clark, G. M., (Keller Mechanical Engineering Corporation). May 7, 1929. Milling-machines.-In a milling or other machine in which a rotary cutter 12 operates upon a workpiece carried on a reciprocating table 1, electromagnetic means is provided for intermittently interrupting the feed of the table when the load on the cutter reaches a predetermined amount. The cutter 12 is rotated from an electromotor 16 connected to leads 17, 18. In series with the lead 17 is an electromagnet 28 cooperating with an armature 26. The table 1 is fed by a leading-screw 2 rotated from an electromotor 11 through magnetic clutches 6 co-operating with discs 7 on a shaft 5. Reversal of the table is controlled by a tumbler switch 19. In operation, when the load on the cutter 12 reaches a predetermined amount the current in the lead 17 rises' and the armature 26 opens a contact 25 to break circuit through the clutch. The feed is momentarily stopped and the resulting drop in the current in the lead 17 allows the contact 25 to be closed. The variation of current through the magnet 28 causes a vibratory motion in the armature 26 and a reduced speed of the leading screw. In a modification, Figs. 3 and 4, not shown, for the magnet 28 and the motor 16 is' substituted a transmission dynamometer in which overloading of the cutter causes depression of an arm to open the contact 25. In both forms means is provided for adjusting the load at which the feed is interrupted.

Abstract: 496,131. Waterproofing animal fibres. 1. G. FARBENINDUSTRIE AKT.-GES. May 24, 1937, No. 14381. Convention date, May 23, 1936. [Class 140] Fibrous material of animal origin, in loose or finished form, is waterproofed by impregnation with an alpha-halogen ether of the general formula R-O-CHX-R<1> (where X is halogen and R and R<1> are alkyl, aralkyl, aryl or cycloalkyl, or R<1> may be hydrogen) and containing a radical of at least 6 carbon atoms, in the presence of a tertiary amine or tertiary polyamine or with an addition product of the alpha-halogen ether and a tertiary amine or tertiary polyamine, in an indifferent solvent or in aqueous solution or suspension, and heating the material during or after impregnation. The hydrophobic effect may be enhanced by simultaneous or subsequent treatment with another waterproofing agent, e.g. aluminium acetate, paraffin wax or a methylol compound of a fatty acid amide of high molecular weight. A further increase of the hydrophobic effect and also fastness to washing may be obtained by performing the impregnation at a temperature above 100‹ C., e.g. 105-110‹ C., or by drying the material below 100‹ C. and subsequently heating at above 100‹ C. Before or during the impregnation, the material may be subjected to the action of an alkylene oxide, e.g. ethylene oxide, propylene oxide, butadiene dioxide or epichlorhydrin. Specified alpha-halogen ethers are the isoheptyl alpha-chlorobutyl, octyl alphachloroethyl, dodecyl chloromethyl, octadecyl chloromethyl, 9.10- dichloro - octadecyl chloromethyl, (iso)octylbenzyl chloromethyl, phenylundecyl chloromethyl and cyclohexyl chloromethyl ethers ; also chloralkyl ethers prepared from alcohol mixtures obtained by reducing commercial fatty acids, e.g. palm oil fatty acids, stearic or oleic acid ; and the chloromethyl ether from alpha-naphthyl carbinol. In examples : (1) a worsted yarn is impregnated with a carbon tetrachloride solution of pyridine and stearyl chloromethyl ether, squeezed and dried at 90‹ C. ; the effect may be improved by an addition of paraffin wax ; (2) dyed wool gabardine, after treatment with ethylene oxide, is passed through an aqueous solution of octadecoxymethyl - trimethylammonium chloride, squeezed and dried at 110‹ C. ; (3) hair felt is treated with a solution of di-(dodecoxymethyl)- tetramethyl-diammonium dichloride and stearic acid methylolamide in tetrachlorethane, centrifuged and dried at 100‹ C. ; (4) military cloth, after dyeing and drumming, is introduced into a suspension prepared by mixing a hot alcoholic solution of stearoxymethyl pyridinium chloride and stearic acid methylolamide with an aqueous solution of aluminium formate, squeezed and dried at 105‹ C.
