Title: Improvements in speed reduction gear
IPC: F16H25/12
Filed: 1930-05-23
Abstract: 355,718. Cam mechanism; variablespeed gearing. MAARSEVEEN, A. C. VAN, 25, Anna van Buerenstraat, The Hague. May 23, 1930, No. 11954/31. Convention date, May 23, 1929. Divided on 355,708, [Group XXVI]. [Classes 80 (ii) and 80 (iii).] The rotor of a rotary engine is mounted on a drum 42, the motion of which is transmitted to a drum 51 and shaft 1 by means of helical cam grooves in the drum 51 and in a reciprocating middle member 48, and balls or the like 46, 49. The ball 46 engages hemispherical pockets in the inner cylindrical surfaces of the drum 42 and member 48, and the ball 49 is similarly related to the member 48 and drum 51. Rotary motion of the drum 42 causes the member 48 to reciprocate and thus the drum 51 to rotate, a reduction of speed being obtained according to the pitches of the grooves. The middle member 48 is shown detached in Fig. 4. The engine shown in Fig. 1 is constructed as described in Specification 355,708. The member 48 is prevented from rotating by means of a sleeve 5 having grooves 4 in which move balls 3. The sleeve is rotated by spur gearing or other means. Speed variation is obtained by varying the ratio of the transmission or reversing the direction of rotation of the sleeve or keeping it stationary.

Title: Hydro-pneumatic spring suspension device especially for motor vehicles
IPC: B60G17/044
Filed: 1965-03-22
Abstract: 1,055,017. Self-levelling hydro-pneumatic suspensions. FICHTEL & SACHS A.G. March 22, 1965 [March 26, 1964], No. 11961/65. Heading F2S. In a self-levelling hydro-pneumatic suspension strut, e.g. for a vehicle when a piston 3 with damping ports 5 moves out of a cylinder 4 and abuts a spring 12 a spring-loaded plate valve 11 is opened and liquid flows from a spring chamber 20 into a reservoir chamber 18 until the piston 3 has again returned into its normal position and no longer rests upon the spring 12. When the piston 3 enters the cylinder 4 sufficiently for the ports 5 in the piston to be closed by a covering piston 6 liquid is sucked past the valve 11 from the reservoir 18 into cylinder 4 so that when the piston 3 descends it pumps liquid through the ports 5 and into the spring chamber 20 the valve 11 being closed. The reservoir 18 is defined by an outer casing 1, the cylinder 4, an end cover 15, and a yieldable wall 10 which is connected by a rigid sleeve 9 with a yieldable wall 8 which closes the lower end of the spring chamber 20 which is formed within the upper end of the casing 1 openings 19 being provided in the upper end of the cylinder 4. The space between the walls 8, 10 is open to atmosphere through a port 21, the walls 8, 10 acting as a differential piston so that the pressure in the reservoir 18 is always less than that in the spring chamber 20 which has a gas filling 36 for supplying the spring work. In a modification, Fig. 2, not shown, in addition to the spring chamber 120 and the reservoir 118 there is provided a high pressure accumulator 123 within a hollow piston rod 122. When the piston 103 descends to abut a spring 129 to open the plate valve 111 and to bridge longitudinal grooves 129 in the inside wall of the cylinder 104 fluid flows from the spring chamber 120 into the reservoir 118 to relieve the pressure within the chamber 120 so that the piston 103 can return to its normal position out of contact with the spring 129. If the piston 103 enters the cylinder 104 enough for a valve plunger 128 with a groove 132 to contact a stop plate 127 then fluid flows from the high pressure accumulator 123 into the chamber 120 until the piston 103 is pushed back within its normal working range. Small oscillations of the piston 103 without the valve plunger 128 or the piston 103 coming into contact respectively with the plate 127 or the spring 129 pumps liquid from the reservoir 118 through a port 131 in the piston rod and past a resilient valve ring 130 into the high pressure accumulator 123 until the yieldable wall 110 comes into contact with a stop ring 126 whereupon no more liquid can be drawn from the reservoir 118. In a further modification. Fig. 3, not shown, which operates in a manner generally similar to the embodiment of Fig. 2, the yieldable walls are located so as to be responsive to pressure in the reservoir and the high pressure accumulator.

Title: Improvements in or relating to control devices and burner control systems
Filed: 1943-07-23
Abstract: 583,851. Gas burners. HONEYWELL-BROWN, Ltd. July 23, 1943, No. 11976. Convention date, July 11, 1942. [Class 75 (i)] [Also in Group XL] A flame-detecting circuit comprises a thermionic tube T2 having its anode supplied by one section 16 of a transformer and having its grid biassed in accordance with the potential of a condenser 49 which is charged in one direction by the grid current of a second tube T1 derived from a second section of the transformer and in the opposite direction from a third section of the transformer acting in conjunction with the rectifying action of the flame 68 or of a photoelectric cell acted on by the flame. When the flame (e.g., the flame of a pilot burner) is out the charge on 49 biasses tube T2 to cut-off and relay 22 remains de-energized and prevents ,the operation of the main burner. When the flame is present relay 22 is able to operate. If, when the flame is absent, the gap becomes bridged by a non-rectifying impedance, the tube T2 is given an alternating bias which, since it is in opposite phase to the anode supply, prevents the operation of 22. The anode circuit of the second tube T1 tends to ensure this @pl.ase relationship when the shunt is of low impedance and also acts as a rectifying circuit, the voltage developed across resistance 60 then tending to bias T2 to cut-off.

Title: Improvements in and relating to the manufacture and production of artificial threads, filaments, films and the like
IPC: D01F2/06
Filed: 1937-04-27
Abstract: Artificial filaments, threads, films, and like materials are obtained by extruding an alkaline solution of cellulose xanthate and casein into a dilute acid bath, and treating the formed materials with a dilute solution of a weak organic acid at or near the boiling point. In an example, a solution of casein in dilute ammonia is mixed with alkaline viscose in such proportion that the mixture contains four times as much cellulose as casein.  The solution is extruded into a bath containing sulphuric acid, sodium sulphate, zinc sulphate, and glucose.  The yarn obtained is washed, desulphured, and washed till neutral.  It is immersed in a very dilute solution of acetic acid at or near 100 DEG  C., and then washed and dried.  The treatment completes the decomposition of the cellulose xanthate which tends to be retarded by the presence of casein.  The Provisional Specification comprises also the treatment of the materials with boiling water instead of dilute organic acid.

Title: Production of aliphatic nitriles from olefins
Inventor: HADLEY DAVID JAMES
IPC: B01J23/28
Filed: 1958-04-16
Abstract: Unsaturated aliphatic nitriles are prepared by heating a mixture of an olefin of formula:  <FORM:0848924/IV(b)/1> wherein R1 and R2 are hydrogen or C1-6 alkyl, with molecular oxygen, ammonia and added steam in the vapour phase at an elevated temperature in the presence of a molybdenum compound as catalyst.  The preferred volumetric proportions in the mixture are: olefin 1-20%; oxygen 2-10%; ammonia 1-10% and steam 20-90%, more preferably 40-60%.  The oxygen may be diluted with inert diluents.  Temperatures of 300-600 DEG  C. are preferred.  The preferred catalyst is molybdenum oxide on a carrier; the carrier may be pretreated by heating or by impregnating it with an inorganic compound, e.g. an alkali metal compound, drying and heating to 1,000 DEG -1,500 DEG  C.  Preferably 1-10% by weight of a sodium compound or 1-20% by weight of a potassium compound is used. The product may be recovered by extracting it into water or other solvent and then distilling.  The residual gases from the wash may be recycled with or without removing carbon dioxide byproduct. Unreacted olefin may be removed from the product by extraction with an oil and recycled.  Again, part of the reaction product may be recycled together with fresh reactant.ALSO:A catalyst composition comprises molybdenum oxide on a carrier such as silica gel, kieselguhr or alumina.  The carrier may be pretreated by heating or by impregnating it with an inorganic compound, e.g. an alkali metal compound, drying and heating to 1000 to 1500 DEG C.  Preferably 1-10% by weight of a sodium compound or 1-20% by weight of a potassium compound is used.  The alkali metal compound may be a hydroxide, chloride, sulphate, carbonate, aluminate, nitrate, phosphate or molybdate.  In an example a catalyst is prepared by impregnating alumina (pretreated with sodium hydroxide) with an ammoniacal solution of ammonium molybdate, drying and heating at 380 DEG C. in a stream of air to form the molybdenum trioxide.

Title: Method and apparatus for laying submarine pipe lines
IPC: F16L1/19
Filed: 1964-03-23
Abstract: 1,016,439. Laying underwater pipes. CALIFORNIA RESEARCH CORPORATION. March 23, 1964 [March 27, 1963], No. 12258/64. Heading F2P. A method of laying a submarine pipe-line on an underwater bottom from a mobile barge on the surface of a body of water comprises determing the minimum radius of curvature R 0 , within the elastic limit of the pipe, of the pipe at the point of tangency with the underwater bottom, while suppported at an upper end by the barge, determining for the specific depth H of water the angle of the slope # of the upper end of the pipe when the lower portion of the pipe is disposed with said radius and controlling the slope of the upper end of the pipe to an amount which does not exceed the angle # calculated, wherein Apparatus for use in maintaining the calculated angle # comprises an elongated frame 17 pivotal in a vertical plane on bearings 15 mounted just above the centre of gravity of the frame. The frame carries a welding head 33, an upper pipe engaging means 25 receiving pipes 29 from a crane and reciprocating in frame 17 to transport the pipes to the welding head, a lower pipe engaging means 39 lowering the pipes until one end is in the welding head to be welded to the end of the succeeding pipe. Means 49 on the frame is used for indicating the angle # at which the frame and hence the pipe end is situated. In a second embodiment, pipe coiled on a drum 50 passes through angleindicating means 51. In operation, a pull-in cable 46 extends from a barge 48 through a pulley in a well-head and thence to a pipe on pipe-laying barge 10. The pipe is fed vertically to within 100 feet of the ocean bottom. Barge 10 is then moved to station C and frame 17 tilts to an angle less than that of # calculated. The pipe is then extended until it lands on the ocean floor at 0. If necessary, the barge is moved to keep the angle less than #. The pipe is then pulled into the well-head terminal and secured to it.

Title: Rotary regenerative heat exchangers
IPC: F28D19/04
Filed: 1963-03-28
Abstract: 999,437. Regenerative heat exchangers. COMBUSTION ENGINEERING Inc. March 28, 1963 [April 4, 1962], No. 12276/63. Heading F4K. In a rotary regenerative heat exchanger comprising a rotor having radial partitions defining compartments in each of which is arranged a frame containing heatcarrying elements, inlet and outlet ducts are provided for the passage of a purging fluid which traverses the frames passing therebetween to remove residual impurities. As shown in Fig. 1, the rotor comprises a cylindrical outer shell 12 a coaxial cylindrical partition 22, radial partitions 16 and frames 24 supporting heat-carrying elements 32 between and spaced from the partitions 16. Air to be cooled enters through an inlet 42 and, as shown in the developed view of Fig. 2, flows in the opposite sense to the direction of rotor movement sequentially through adjacent frames of the rotor. Upper and lower multi-compartmental ducts 60, 55, which are mutually offset, are provided to enable the air to flow around the intervening partition 16 between the frames. After passing through two frames the air leaves the rotor through a duct 62, which bypasses four further frames, and is returned to the rotor through a duct 78 for passage through two more frames. During the latter passage the air is cooled to a temperature at which the moisture condenses therefrom. A second duct 68 enables the air to by-pass four more frames of the rotor, the air being returned through a duct 86 for passage through two final frames at which carbon dioxide condenses from the air. The cooled air leaves the rotor through a duct 44. Condensed carbon dioxide is removed from the rotor frames as they pass between the inlet and outlet of bypass duct 68 by a purging fluid, e.g. liquid nitrogen, which is supplied to and withdrawn from the rotor through an inlet 72 and an outlet 74. Similary, condensed moisture is removed intermediate the by-pass duct 62 by a further purging fluid admitted through a duct 64 and withdrawn through duct 66. Liquid hydrogen is used as the coolant in the regenerator and is admitted through duct 46 and withdrawn at 48 there being further purging arrangements 57, 58 and 53, 54 immediately upstream and downstream respectively of the ducts 46 and 48 in the direction of rotor movement.

Filed: 1937-04-30
Abstract: 494,691. Two -- stroke engines. BENNET, C. W. H. D. April 30, 1937, Nos. 12309 and 12310. Convention dates, April 30, 1936 and March 30,1937. [Classes 7 (ii) and 7 (vi)] In a two-stroke engine, the crank-shaft, which is in driving connection with the piston or pistons and is rotated relatively to the cylinder or cylinders, forms a ported part of each cylinder head and receives the direct pressure of the combustion within each cylinder. The combustion chambers are cylindrical and located between the piston or pistons and the crank-shaft. As applied to a radial engine, the combustion chambers are disposed between differential pistons 5, Fig. 6, and the crankshaft 9 to which the pistons are linked by connecting rods 7. A recess 18 in the crank-shaft puts the combustion chambers successively in communication with passages 17 each leading to a precompression chamber in the preceding cylinder above the piston 5, the arrangement ensuring an increasing discharge pressure as the charge is forced into the combustion chamber for scavenging. The precompression chamber may be larger than the combustion chamber. Opposite the recess 18 in the crank-shaft 9 is an igniter 22 which may take the form of a simple passage permitting the burning gases in one cylinder to fire the charge in the next one. In a modification, Fig. 9, the crank-shaft terminates in a ported boss 9a surrounded by a stationary sleeve 30 on which the transfer passage 17 is mounted. Passages 32, 15a in the crank-shaft place the passage 17 in communication with either an enlarged chamber 34 in the crank-shaft or an air inlet 31 and the time and dimensions of the opening of the passage 17 into the passage 32 are determined by a two-part sleeve 35 between the sleeve 30 and the boss 9a adjustment of the parts of the sleeve determining the position and size of the opening in the sleeve. A fuel injector may be disposed in the crank-shaft in the case of a Diesel engine, or a fuel nozzle be similarly disposed or a carburetter supply the inlet 31.

Title: Manufacture of basic esters of 4-amino- and 4-alkylamino 3-alkoxybenzoic acids
Filed: 1948-05-05
Abstract: The diethylaminoethyl ester of 3-butoxy-4-aminobenzoic acid is prepared by esterifying 3-butoxy-4-nitrobenzoic acid chloride with diethylaminoethanol and then reducing the nitro group.  The ester is useful as a local anaesthetic.  In an example, 3-oxy-4-nitrobenzoic acid ethyl ester is treated with KOH in methanol and then with butyl bromide to give the butoxy-nitrobenzoic acid ethyl ester, which is saponified with alcoholic potash and converted to the acid chloride by treatment with thionyl chloride.  The acid chloride is esterified in benzene with diethylaminoethanol to give 3-butoxy-4-nitrobenzoic acid diethylamino-ethyl ester which is then hydrogenated in presence of Raney nickel to yield 3-butoxy-4-amino-benzoic acid diethylamino-ethyl ester.  The ester may be converted to its dihydrochloride by passing hydrochloric acid gas into a solution of the ester in ether.  The Specification as open to inspection under Sect. 91 refers generally to the preparation of basic esters of 3-alkoxy-4-aminobenzoic acids by esterifying the 3-alkoxy-4-nitrobenzoic acid chloride with an amino alcohol, reducing the nitro group and, if desired, alkylating the amino group, e.g. with methyl or ethyl bromide.  The preparation of 3-propoxy-4-aminobenzoic acid diethylaminoethyl ester is referred to. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the cooling of dynamo electric machines
IPC: H02K9/16
Filed: 1933-04-28
Abstract: 413,835. Cooling dynamo - electric machines. EHRMANN, P., 60, Rue Madame, Paris. April 28, 1933, No. 12416. Convention date, April 30, 1932. [Class 35.] An internal current of air traverses the rotor twice from end to end in opposite directions, being cooled between the traverses, and during the traverses it flows through ducts parallel with the planes of the laminµ in the rotor core. In the form shown in Figs. 7 and 8, the rotor laminµ have arcuate apertures, and they are superimposed in such a manner as to provide axial ducts 5<1>-5<4> and circumferential ducts 30, whilst an oblique partition 22 is arranged in each axial duct to divide it into two compartments closed at one end. The air current f<4> enters one compartment of duct 5<2>, travels circumferentially and is sucked out of duct 5<1> or 5<3> by fan 12<1> as indicated by arrow f<1>, Fig. 7, which Figure shows half-sections in two mutually perpendicular planes. It is then cooled by flowing over ribs 7<1> before entering the other compartment of duct 5<2> or duct 5<4> and it re-emerges from the rotor from duct 5<1> or 5<3> and is again cooled. In addition to the outlets for these currents, the fans have portions 131, 13<2> designed to circulate air locally about the end windings 9<1>, 9<2> and the partitions 15. In the form shown in Fig. 1, the rotor has its ducts separated by the arms 21<1>-21<4> of the spider 20, and partitions 22 are provided to force the air to enter the circumferential ducts 25 during its passage from one end of the machine to the other, the arrangement of the machine apart from the rotor construction being similar to that already described. The Specification as open to inspection under Sect. 91 comprises also arrangements wherein the air passes straight through the axial rotor ducts without entering circumferential passages, whilst in a further modification it does not traverse the rotor in both directions, but returns through ducts 40, Fig. 18 (Cancelled), in the stator core. In this arrangement, the stator laminae have fins 50 at intervals around their circumference, which project into the path of the external current of air f<10> and the rotor may have circumferential ducts and partitions in its axial ducts 5<1>, 5<2>. This subject-matter does not appear in the Specification as accepted.
