Filed: 1925-02-18
Abstract: 252,076. Douglas Motors, Ltd., and Pullin, C. G. Feb. 18, 1925. Channels in ball or roller bearings and cranks.-One or both ends of the inner race 5 of a ball or roller bearing 6 for the big-end of a connecting-rod is chamfered at 7 to provide an annular space around the crank-pin 4. This space is in communication with oil supply passages 9, 10 in the crank-shaft, and communicates with the bearing face of the race by radial channels 11 cut in the end of the race or in the face of the crank-web 8 or in both. Instead of chamfering the end of the race, the annular space may be formed in the periphery of the crank-pin or in the face of the web.

Title: Process for the manufacture of filamentary materials of regenerated cellulose by spinning viscose
IPC: D01F2/08
Filed: 1961-02-07
Abstract: In viscose spinning, there is added to the viscose, and/or to the coagulating bath, an ethylene oxide addition product of a compound having at least 8 carbon atoms which contains an amide, sulphonamide or a primary or secondary amino group and in which the terminal hydroxyl group of the polyethylene oxide chain is substituted by an alkylamino residue having 2-3 carbon atoms.  The compound may contain an aliphatic, aliphatic-cycloaliphatic, or aliphatic-aromatic hydrocarbon residue with 8-20 carbon atoms and a polyethylene oxide chain with 5-40 mols. ethylene oxide. Specified compounds are as follows:-  <FORM:0905149/IV(a)/1> <FORM:0905149/IV(a)/2> <FORM:0905149/IV(a)/3> <FORM:0905149/IV(a)/4> <FORM:0905149/IV(a)/5> <FORM:0905149/IV(a)/6> These compounds are derived from high-molecular amines and acid amides which contain aliphatic, aliphatic-cycloaliphatic, or aliphatic-aromatic hydrocarbon residues, indicated by R, having 8-20 carbon atoms, and contain polyethylene oxide residues having 5-40 mols. ethylene oxide per molecule, the alkyl amino groups having 2-3 carbon atoms.  Such compounds may be made by treating the ethylene oxide addition products with acrylonitrile followed by hydrogenation, or by treatment of the ethylene oxide addition products with ethylene imine, e.g. the hydrogenated reaction product of acrylonitrile with the addition product of 9 mols. ethylene oxide to 1 mol. dodecylamine, the hydrogenated reaction product of 1 or 2 mols. acrylonitrile with an alkylamine mixture having 8-18 carbon atoms made on the basis of coconut oil and reacted with 8 mols. ethylene oxide, the reaction product of ethylene imine with the addition product of 12 mols. ethylene oxide to 1 mol. oleic acid-N-methylamide, the mono-g -amino propyl ether of the addition product of 12 mols. ethylene oxide to either (a) 1 mol. fatty acid mono-ethanolamide (fatty acid residue C12-C18), or (b) 1 mol. of an alkylamine mixture (C6-C18 alkyl residues), or the bis-g -amino-propyl ether of the addition product of 12 mols. ethylene oxide to 1 mol. of an alkylamine mixture (C8-C18 alkyl residues).  In the examples these compounds are added to the viscose before ripening.  From 0,01-0,5% by weight of the compound calculated on the viscose, or on the coagulating bath, as appropriate, may be added, and the viscose may be spun into an acid coagulating bath which contains at least 35 g/l. ZnSO4, preferably 35-105 g/l. ZnSO4, and 60-100 g/l. H2SO4.  Desirably, the bath contains 95 g/l. ZnSO4 and 75 g/l. H2SO4.  The filaments may be stretched in a second, weak acid bath.  Filaments so made have a round or bean-shaped structure with a full or thick shell, and a smooth periphery, and show higher strengths and lower swelling values compared with conventional filaments.  The filaments are suitable for use in tyre cord.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 17, 1933]. [Class 7 (iii).] Heavy oils, such as those obtained by the dry distillation of naptha or coal, are fed from a tank 1, in which the fuel is maintained under pressure, through a pipe 4 into a coil 5 in the exhaust pipe 14, through maze-like conduits 61 of reduced cross-section in a plate 6, past a valve 7, operatively connected to an airadmission valve 16, into a further coil 10 in the exhaust pipe.

Title: Improvements in automatic devices for actuating gates and the like
IPC: E05F15/04
Filed: 1930-02-13
Abstract: 348,583. Operating gates. ALEXANDER, E. M., of Mortimer's, Milton, Northampton. Feb. 13, 1930, No. 4924. [Classes 44 and 65 (i).] A pair of inclined tracks 12, 12a, Fig. 2, are fixed at their upper ends to a spindle 14 and at their lower ends to a frame 13. Trolleys carrying tanks 8, 19 run on the tracks 12, 12a respectively, and are connected by cords passing over pulleys 18. A cord 26 supporting a heavy bar 28 passes over a pulley carried by the spindle 14 and is connected to the trolley 19 ; it is of such length that it is taut only when trolley 19 is at or near the lower end of the track 12a. Each tank is provided with an outlet valve 25 which is opened by striking a projection 24 at the lower end of the track and is closed by striking a similar projection at the upper end of the track; the valve consists of pipe 25 which slides in a tube 25<1>, Fig. 3, fixed in the tank, to bring ports 46, 46<1>, into or out of register. When the gate is closed, trolley 19 is at the lower end of its track, trolley 8 at the upper end, both tanks are empty, and bar 28 is raised. When a vehicle stands on either of the treadles 4 a spring-closed valve 1 is opened, and water flows by pipe 6 and a flexible pipe into tank 8, which therefore runs down its track 12 and swings the frame 13 to the position shown, thus pulling rod 35 to unlatch and open the gate; trolley 19 is pulled up, and bar 28 is lowered to engage with catches 31 to prevent oscillation of the frame. The swinging of the frame also opens a valve 34, by means of a lever 32 which works in guides on the frame, and admits water by pipe 21 and a flexible pipe to the tank 19. When tank 8 reaches the bottom of its travel it commences to empty, while tank 19 is filling. After an interval, determined by the rates of inlet and outlet of water in the two tanks, tank 19 be comes heavier than tank 8 and runs down its track, raising bar 28 clear of the catches 31, swinging the frame 13 back to its original position to close the gate and to close valve 34, and pulling up tank 8. When tank 19 reaches the bottom of its track, it empties, thus restoring the original conditions. Each catch 31 is pivoted to a strap 47, Fig. 4, fixed to the side member of the frame 13, and its upwardly curved engaging part is held normally raised by a tension spring 48, which yields to free the catch if the gate is forcibly closed ; a piece 49 pivoted to the catch 31 prevents the bar 28 from engaging under the catch 31.
