Title: Improvements in carburetors provided with an auxiliary starting carburetor device
Inventor: MENNESSON ANDRE LOUIS
IPC: F02M1/04
Filed: 1954-05-14
Abstract: 752,695. Carburetters. SOLEX. May 14, 1954 [June 12, 1953], No. 14248/54. Class 7(3) In a carburetter including an auxiliary starting carburetter device capable of forming and feeding into the induction pipe a rich mixture of fuel mixed with air and additional starting air, with a valve system actuated by a thermosensitive member for controlling the feed of fuel to the auxiliary starting device, the valve system includes means capable of locking it in the position it occupies when it stops the feed of fuel to the auxiliary starting carburetter device, the locking means being arranged to be brought out of action by the carburetter throttle valve control means when the throttle valve is being moved from its maximum closing position. As shown a starting carburetter distributing valve 26 is controlled by a bi-mettallic strip 49. In one position the valve permits feed of fuel downstream of the throttle valve in another position it connects the starting carburetter with a conduit 27 and with a conduit 29 which opens into the induction pipe upstream of the throttle valve and for instance into the venturi 3 at its throat or downstream of the throat. In a third position the conduit 24 is closed. When the valve is in the latter position it can be locked in this position by means of a roller 43 carried by a lever 44, the roller being urged into a notch 64 in a cam 40 carried on the valve spindle 39 when the throttle valve is released. When the throttle valve is opened the locking device is released. The cam 40 is arranged so that when the valve 26 is brought into a position in which fuel is supplied to the downstream side of the throttle, the throttle valve is slightly moved in the opening direction. The cam effects this opening through the medium of the roller 43 and the lever 44. When the engine is being driven by the starter the mixture is enriched by means of a valve 59 which co-operates with the orifice 20 of the starting carburetter fuel well. When the engine has been started the valve is lifted thus reducing the feed of fuel. The conduit 21 is in communication with the well 18 through one or several orifices such as 22. A permanent venting hole such as 62 may be provided at the top of the well. The opening of the throttle when the auxiliary starting device is brought into action is limited by the fact that it must not start the feed of fuel through the main nozzle 4. If this opening does not supply the engine with a sufficient amount of air to start it, it is necessary to provide a complementary air feed controlled by the auxiliary carburetter control valve. A hot spot may be provided by a common wall between the induction pipe 16 and the exhaust pipe 17.

The longitudinal edges of a wrapping sheet folded in tubular form about a slice of cheese, overlap to form an unsealed lap joint 14, Fig. 1, with the edge of the outer layer folded back; the ends of the wrapper are seamed to form releasable fin seals 17, 18. A group of wrapped slices may be enclosed in a wrapper of a similar nature, the end seals of which may be crimped. Wrapping conveyers.-Wrapping material, fed from a roll 23, Fig. 7, is entubed around cheese slices 12, fed by a conveyer 42, in an adjustable forming device 24. The portions of the tube between adjacent slices are sealed by sealer 26 and severed by rotary cutters 186. Prior to wrapping the slices are laterally aligned at a station 27, comprising a pair of belts 67, 68. As a slice 12, Fig. 15, enters the alignment station, the side edges of the slice are raised on rollers 59 (Fig. 15) and the whole slice is raised from the conveyer by a cushion of air, blown from tubes 62. In this way the slices may easily be moved into lateral alignment by the belts 67, 68.

Title: New phthalazines and process for their manufacture
IPC: A61J1/06
Filed: 1958-05-07
Abstract: The invention comprises 1-hydrazino-4-(pyridyl-methyl)-phthalazines and acid addition salts thereof, wherein the benzene nucleus may further contain as substituents lower alkyl, amino or lower alkanoylamino groups ("lower" indicating 1-6 carbon atoms in the group), and the preparation thereof by reacting an appropriate 1-chloro-4-(pyridyl-methyl)phthalazine with hydrazine, and optionally hydrolysing the alkanoylamino group to form the amino group. 1-Chloro-4-[pyridyl-(41)-methyl]-phthalazine is prepared by condensing phthalic anhydride with 4-methylpyridine to form g -pyrophthalone which is heated with hydrazine to give 1-oxo4-[pyridyl-(41)-methyl] - 1:2-dihydrophthalazine and the last named compound is treated with phosphorus oxychloride and ammonia.  1 - Chloro-4-[pyridyl-(21)-methyl]phthalazine is similarly prepared through a -pyrophthalone and 1-oxo-4-[pyridyl-(21)-methyl]-1:2dihydrophthalazine. 1-Chloro-4-[pyridyl-(41)-methyl] - 7 - acetylamino-1,2-dihydrophthalazine is prepared by reacting 5-nitro- -pyrophthalone (from 4-nitrophthalic anhydride and g -picoline) with hydrazine to form 1-oxo-4[pyridyl-(41)-methyl]-7-amino-1:2-dihydrophthalazine, reacting the phthalazone with acetic anhydride to form 1-oxo-4-[pyridyl-(41)-methyl] - 7 - acetylamino1,2-dihydrophthalazine and treating this with phosphorus oxychloride.ALSO:Pharmaceutical compositions comprise 1-hydrazino - 4 - (pyridyl - methyl) - phthalazines wherein the benzene nucleus is unsubstituted or substituted by amino, lower alkanoylamino or lower alkyl groups ("lower" indicating 1-6 carbon atoms in the said groups) and acid addition salts thereof, together with a pharmaceutical carrier suitable for enteral or parenteral administration.  The compositions may be in the form of tablets, dragees, pearls, capsules or in liquid form; they may additionally contain auxiliary substances such as preserving, stabilizing, wetting or emulsifying agents, salts for regulating osmotic pressure or buffers, or other therapeutically valuable substances. Preferably they contain 0.5-45.0% of the active phthalazine. Specified salts are hydrohalides, sulphates, nitrates, phosphates, thiocyanates, acetates, propionates, oxalates, malonates, succinates, citrates, tartrates, malates, methane-, ethane-, hydroxyethane-, benzene- and toluene-sulphonates, and salts with amino-acids and therapeutically active acids.

Title: Improvements in or relating to the manufacture of prints and photographic material therefor
IPC: G03B15/00
Filed: 1956-05-11
Abstract: 804,076. Photographic copying process and matrix therefor. GEVAERT PHOTOPRODUCE N. V. May 11, 1956 [May 11, 1955], No. 14766/56. Class 98(2) Prints are made by exposing a silver halide material containing a finely-divided water-insoluble colour component, tanning development, removing unhardened parts to form the matrix, and contacting this with a print paper in the presence of a liquid to convert the colour component into dyestuff and to dissolve the dyestuff, so that a coloured positive copy of the original appears on the print paper. Four examples use direct positive material by reflex exposure and a fifth uses ordinary material, also reflex but with a reversal, thus in Example 1 leucomalachite green dissolved in ethanol is stirred into a direct positive silver chloride emulsion and the product is applied to baryta coated paper, dried, reflex exposed, treated with a specified pyrocatechol developer, bathed in warm water, and contacted in the presence of aqueous oxalic acid with paper coated with a layer comprising gelatine, barium sulphate and potassium permanganate to give a green copy, a hundred of which may be obtained by repeating the printing step. Example 2 uses leuco crystal-violet similarly but strips of unhardened parts of the emulsion by transfer of them to paper instead of by bathing in warm water, to result, finally, in violet reproductions. Examples 3, 4 repeat the procedures of Examples 1, 2 respectively with variations of details. In Example 5 an ordinary silver chloride emulsion treated with leucomalachite green in the manner of Example 1 is reflex exposed, developed with metolhydroquinone, re-exposed and then further treated as in that example. Indication of the manner of procedure for producing positive copies by contact or projection printing from transparent originals is provided in the Specification. Other oxidants and acids for releasing dye from the leucobases are refermed to .
