Title: Improvements in charge-forming processes and devices for internal combustion engines
IPC: F02M25/07
Filed: 1925-12-17
Abstract: 244,792. Moore Inventions Corporation, (Assignees of Moore, A.). Dec. 19, 1924, [Convention date]. Vaporizers, external; heating charge; spray carburettors. - To vaporize liquid particles of fuel in the mixture to prevent knocking, a mixture of hot air and exhaust gas is added to the mixture at reduced throttle openings, the air being cut off and the amount of the exhaust gas increased as the throttle is moved from the partly open to the fully open position. The air is heated and mixed with the exhaust gas in a device 30 provided with an inlet 32 for exhaust gas from the manifold 16, and with an annular chamber 62 open to the air adjacent the exhaust manifold 16, the chamber 62 being surrounded by an insulating air jacket 58. The hot exhaust gas passes upwardly through the chamber 46 and over the baffle 76 to an outlet port 70 controlled by a valve 66, and the air passes through the chamber 62 to an outlet port 88 controlled by a valve 64. The air and exhaust gas mix in an annular chamber 90 which communicates through a valve 110 with a conduit 34 opening into the induction pipe 20 above the throttle 24, and through a needle valve 112 with a conduit 40 opening into the carburettor below the throttle. The valves 64, 66, 110 are operated by a common rotatable cam member 118 interconnected with the throttle control, and provided with a peripheral cam 121 actuating the valve 110, and with a face cam 123 coacting with adjustable pins 128, 130 to actuate the valves 66, 64. The exhaust valve 66 is provided with ports 82 which open into the chamber 90 when the valve 66 is closed and are controlled by a manually-adjustable needle valve 78. The valves are adjusted and actuated so that when the engine is idling the valves 66 and 110 are closed and the valves 64 and 78 open, a mixture of air and exhaust gas controlled by the valve 112 being drawn through the conduit 40 into the carburettor; at reduced throttle openings, the valve 110 is opened and the mixture also passes through the conduit 34 to the induction pipe; as the throttle is further opened, the exhaust valve 66 is opened and the air valve 64 closed, exhaust gas alone then passing to the induction pipe.

Abstract: 351,869. Aircraft with adjustable rotary wing systems. SERRAGLI, G., 79, Via Cavour, Florence, Italy. Oct. 24, 1930, No. 31973. Convention date, Oct. 24, 1929. [Class 4.] An aeroplane is fitted with a braking airscrew loosely mounted on a shaft at right-angles to the thrust axis and formed with four fixed blades, three of zero pitch and one, Pd, Figs. 1 and 3, set at an angle of 15-20‹ to act as a steadying fin when the plane of rotation of the airscrew includes the direction of motion of the aeroplane. On the incidence of the aeroplane being increased, as by stalling, the airscrew revolves to retard the machine. The airscrew hub N, Fig. 2, is mounted on a transverse pivot a forming part of an arm b and supported by tripod struts M, m<1>, m<2>. The inclination of the hub N may be varied by means of a link l connected to arm b and to a collar f slidable along the strut M under the control of the pilot. Rotation of the airscrew may be prevented in normal flight by a tooth s engaging in a notch in the hub N.

Abstract: 1,156,021. Ribofuranosyl - 7 - deazapurine cyclic 3<SP>1</SP>,5<SP>1</SP>-phosphates. UPJOHN CO. 18 July, 1966 [5 Aug., 1965], No. 32188/66. Headings C2A and C2C. Novel 9 - # - D - ribofuranosyl - 7 - deazapurine cyclic 3<SP>1</SP>,5<SP>1</SP>-phosphates of the general formula wherein Z is hydrogen, hydroxy, amino, acylamino having 2-12 carbon atoms, mercapto or alkyl mercapto having 1-4 carbon atoms are prepared by treating a 9-#-D-riboside-7-deazapurine-5<SP>1</SP>-phosphate in basic solution containing a strong base with a condensing agent. The condensing agent is preferably a dialkyl or dicycloalkyl carbodiimide such as dicyclo. hexylcarbodiimide. The preferred solvent is pyridine and the reaction mixture is preferably evaporated to dryness several times to ensure absolutely anhydrous conditions. The condensation reaction is carried out by refluxing the mixture for up to several hours, and then adding water and recovering the product. The starting material 9-#-D-ribofuranosyl- 7 - deazaadenine - 5<SP>1</SP>- phosphate is prepared by treating 9 - # - D - ribofuranosyl - 7 - deazaadenine, prepared by a fermentation process in accordance with Specification 974,541, from Streptomyces sparsogenes var. sparsogenes, NRRL2940, with p-toluene sulphonic acid monohydrate and acetone, cooling, basifying with NaHCO 3  solution and evaporating to dryness. The 2<SP>1</SP>,3<SP>1</SP>-O-isopropylidene compound so formed is extracted with chloroform, crystallized and treated with #-cyanoethyl dihydrogenphosphate in pyridine solution, the resulting mixture being evaporated to dryness and then treated with N,N<SP>1</SP>-dicyclohexylcarbodiimide in pyridine solution. The product is mixed with water, filtered and the aqueous layer solvent extracted and evaporated to dryness under reduced pressure. The residue is boiled with LiOH solution, filtered and the filtrate extracted with ether. The aqueous layer is passed through a cation exchange resin (IRC50) and eluted, the eluate and washings acidified with H 2 SO 4  and boiled. Barium sulphate is then added to give the barium salt of 9-#-D-ribofuranosyl-7-deazaadenine, as well as some of the lithium and sodium salts and the products then applied to an ion exchange column to give the desired product. The 2<SP>1</SP>,3<SP>1</SP>,O-isopropylidene- and 5<SP>1</SP>- phosphate derivatives of 6-methylmercapto-9- # - D - ribofuranosyl - 7 - deazapurine (obtained by methylation of the corresponding mercapto compound with MeI) are prepared, in a manner similar to that described above, from 6-mercapto - 9 - # - D - 7 - deazapurine. The products (I) have significant cytotoxic activity in vitro against KB tumour cells and viruses such as Herpes, Coe and vaccinia viruses. The compounds can be administered orally, parenterally or topically in acceptable pharmaceutical carriers. The antiviral activity of the products may be of use in preparing cultures of microorganisms free of viral phages such as phagefree, antibiotic-producing Streptomyces cultures.

Title: Controllers for reversing electric motors
IPC: B23Q15/00
Filed: 1957-10-15
Abstract: 819,620. Screwing and tapping. HENRIKSSON, R. Oct. 15, 1957 [Oct. 15, 1956], No. 32230/57. Class 83 (3). [Also in Group XXXVII] Switches M, N, for reversing the three-phase current supplied to an electric motor which drives a tapping- or screwing-machine, become operative when the tool reaches predetermined limits during its upward or downward travel. The switches are mounted on a disc 6 which is driven, in common with a disc 5, from the machine, the latter disc having contact rings 8-11 co-operating with brushes for conveying current to the switches. A lever is coupled by a spring to the switch arms to provide snap action thereof. When, during rotation of the disc 6, the lever engages a cam 27 fixed to a rod 29, contacts x, z are closed to reverse the motor. Reversal of the motor is again effected when the lever engages a cam 28 to close contacts v, y. The position of the cam 28 is adjusted by a handle 32 which turns a friction-held disc 30 upon which the cam is mounted, thus determining the cutting depth of the tool. If the machine is to be used for drilling only, the switches M, N are short-circuited by a manually-operated switch.

Title: Method and apparatus for forming a cigarette rod
IPC: A24C5/18
Filed: 1977-08-02
Abstract: 1532721 Automatic control of cigarette machine HAUNI-WERKE KORBER & CO KG 2 Aug 1977 [6 Aug 1976] 32293/77 Heading G3R In a cigarette rod machine of the type in which excess tobacco in a supply stream is removed and recirculated, the height of the stream before and after removal is measured and the values "correlated" (quotient or difference is obtained) to form a control signal for adjusting the supply. The object is to minimize the excess, which is deteriorated by being recirculated. In the embodiment, the height of the stream before trimming 4 is detected by an array of photo-cells 38 associated with a light source 29 and that after trimming is taken to be that of the trimming knife 6 which is measured by an inductive device 8. The quotient of these values is obtained at 42, is indicated at 43, and is compared with a desired value from potentiometer 47 at 46. Any difference is multiplied at 48 by a speed signal from a tacho 49 on the main drive 51 of the machine. The result is used as the set point for a closed loop system which controls the speed of a feed motor 54. The height of the trimming knife is controlled in a known manner in response to a radiation gauge at the output of the rod forming section.
