IPC: G03C1/52
Filed: 1932-01-13
Abstract: 383,791. Photographic diazotype processes. FILM OZAPHANE, 5, Avenue Percier, Paris. Jan. 13, 1932, No. 1072. Convention date, Feb. 16, 1931. Drawings to Specification. [Class 98 (ii).] Films and papers are sensitized with diazo compounds in such quantity that the maximum optical density of the resulting dye image exceeds 1.6 on a scale defined in the Specification. The papers may be printed from toned or untoned silver images the gamma of which is sufficiently low to ensure that the darkest shadow is rendered on the print by a density less than three-quarters of the maximum density. To ascertain whether the concentration of the sensitizing bath is correct, a strip of film is sensitized, developed without exposure and the optical density measured. The concentration of the bath is then altered in proportion to the change of density required. In an example of a sensitizing bath, a film of regenerated cellulose is soaked in a solution comprising 2 : 1 : 4 - diazonaphthol sulphonic acid, phloroglucinol, glycerin, lactic acid, ammonium fluotitanate and the material known under the Registered Trade Mark "Nekal B. X."

Abstract: 468,344. Rolling. SCHLOEMANN AKT.- GES. Jan. 15, 1937, No.. 1307. Convention date, Jan. 15, 1936. [Class 83 (iv)] The pivoted end flap 28 of a loop return guide is opened by an electric motor 32 started up by the formation of the loop therein, and is closed by reversal of the same motor after a timed delay set in relation to the length of the strip. When the strip W between rolls 1 and 2 follows the curve of the guides and is gripped between the upper rolls 2 and 3, the loop formed begins to push the flap 28 out so that the linkage 30 rotates a cam disc 33 on the motor shaft so opening contact a so that relay B is de-energized, closes its contact b<1>, opens contact b<2> and b<3> in the phase conductors R and S. Closing b<1> excites time delay relay C and through C, which at first still holds, excites relay D. This closes contacts d<1> and d<2> in the phase conductors R and S so interchanging the phases U and V to reverse the motor 32 to raise the flap 28 until the rod and lever 30 strikes the stop 34. The loop of material can now issue freely. The flap 28 remains open until the contact c of the set time delay relay C opens (or until the trailing end of the strip passes and allows a switch to effect this) whereupon relay D is de-energized and opens its two contacts d<1> and d2 to temporarily deprive the motor 32 of current so that the flap 28 sinks under its weight at first until the cam disc 33 revolves with it so far that contact a closes again so exciting relay B, closing b<2> and b<3>, opening b<1>, de-energizing time delay relay C so interchanging back the phases U and V to reverse back the motor to complete the closing of the flap 28 the rod &c. 30 coming against the stop 35. The guide also comprises a pivoted auxiliary flap 26 which can be opened by releasing wedges 27, to allow test pieces to be taken from the strip. Nuts 19 adjust the spacing of the ends of the half guides 10, 11 which are pivoted at 14. The bottom guide entrances are tipped with bronze pieces 20, 22. Side guides 37 complete the enclosing of the channel, these guides 37 being adjusted as required to suit the width of the strip by notched adjusting bars 38.

Title: Improvements in or relating to testing combustible fluids
IPC: G01N25/52
Filed: 1932-01-19
Abstract: <PICT:0394736/III/1> Fuels and other combustible liquids are tested to ascertain the temperatures at which they ignite spontaneously in heated air, and the intervals at various temperatures between contact with and ignition or explosion in the heated air.  Fuels are thus graded according to their suitability for use in compression ignition engines.  Using the apparatus shown, the iron explosion cylinder 1 is heated by electric coils 5 to the highest investigation temperature, e.g. 600 DEG  C., the heater turned off, a charge of cold air drawn in through an opening in the cover 12 by a pump attached to a pipe 14, and when the temperature of the air reaches a maximum and begins to fall a fuel charge is forced in through a passage 20 and a valve 21 so as to form a conical spray which does not touch the heated sides of the cylinder.  The moment of injection is recorded electrically through the lifting of the valve 21 raising a tappet pin 24 which moves a block 25 pivoted on pins 26 so that contacts 29, 30 are separated and an electric circuit broken.  The moment of ignition or explosion of the fuel is similarly recorded through the lifting of a valve and pin raising a lever 36 on pivots 37 so as to separate contacts 38, 39. The explosion cylinder is then cleared by sucking in fresh air, and the test is repeated at successively lower tempera <PICT:0394736/III/2> tures of say 10-20 DEG  C.  The recording device comprises a paper strip which is moved along an insulating trough so as to be pierced at one side by sparks from a fixed sparking point 49 of the injection timing circuit and at the other by sparks from a vibrating sparking point 50 of the ignition timing circuit.  The circuits for the injection and ignition recording are in parallel, and comprise low tension coils 42, 43 respectively with associated high tension coils 47, 48, tremblers 41, 420, and contact breakers 28, 36; the coils are earthed at one end 44, the L.T. coils being connected at the other end through a switch 45 to a battery 46, and the H.T. coils to the sparking points 49, 50.  The point 50 is on a reed 59 vibrated by a circuit comprising the reed 59, an adjustable contact 60, electromagnetic coils 61, a switch 62, and a battery 63. The pump for injecting the fuel is of the kind in which a small charge of fuel is forced by a plunger past a spring-loaded non-return valve in the pipe leading to the injection nozzle, the plunger being operated with a given force by the fall of a pivoted weighted lever.
