Title: Improvements in methods and means for the screen projection of acoustic cinematographic films with continuous travel
IPC: G03B31/00
Filed: 1928-09-19
Abstract: 300,235. Soc. des Etablissements Gaumont. Nov. 9, 1927, [Convention date]. Optical records and apparatus. - Talking- picture films are'constructed with a sound record which is reproduced by radiations, such as ultraviolet. outside, the range of the visible radiations which reproduce the picture, a beam from a single source emitting both the visible and the special radiations being employed for picture projection and sound reproduction. The sound record may be superposed on the picture record, which moves continuously during projection. Fig. 1 shows a reproducing apparatus for the talking- picture film, employing as a single source of radiations carbons with a mineral core. Radiations frorn this source A pass through a condenser C, through the image i of the superposed records on the film F, and through a lens O<1> and inclined glass plate R on to the picture screen E. A small portion of the radiations falling on the plate R is reflected through a lens O<2> and a selecting screen E<1> on to a photo-electric cell. The screen E' may be a Wood screen, consisting of a nickel oxide glass, which arrests all radiations below 3650‹ A. but permits the cell to be affected by radiations above this wave length, which have been influenced by the sound record on the film F. In a modification, the glass plate R is replaced by a quartz plate silvered on the side adjacent the film. This plate reflects the greater part of the radiations through a lens on to a picture screen but permits the passage of ultra-violet radiations which, influenced by the sound record, pass through the plate and a lens and slit on to a photo electric cell. The Specification as open to inspection under Sect. 91 (3) (a) states that the two classes of radiations may be provided by different sources arranged on the same optical axis, and refers to Specification 297,733 for the preparation of the record. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in method for imparting durable lustrous finish effects to fabrics
IPC: D06C21/00
Filed: 1955-09-22
Abstract: 784,764. Finishing fabrics. BANCROFT & SONS CO., J. Sept. 22, 1955 [Oct. 18, 1954], No. 27070/55. Class 42 (1). A fabric, which has previously been treated with an impregnant capable of fixing finish effects on the fabric by forming a thermoset resin or by reacting with the fabric, is passed while still moist through a drum and blanket or belt type finishing machine adjusted, as regards temperature of the drum and contact pressure of the fabric, to impart a subdued lustre finish to the fabric, and is thereafter heated in a separate curing device to set or react the impregnant and fix the finish effect. As shown, fabric F is impregnated at 4 with a thermosetting resin pre-condensate. It is dried at 5 to a moist condition and given a lustre finish in a blanket and drum compressive shrinkage machine 8, 10 adjusted to impart little or no shrinkage, the pressure shoes 15 being at a temperature of 300‹ to 400‹ F., the pressure of the blanket 8 on the drum 10 being 3.5 ounces to 3 lb. per square inch, and the temperature of drum 10 being 230‹ to 300‹ F. Drum 10 provides little, if any, curing of the resin; curing is effected, to fix the lustre effect, by heating in an oven 6 at 260‹ to 400‹ F. A rubber belt type shrinkage machine may be used instead of machine 8, 10; or two drum and blanket machines may be used in series to impart a lustre effect to both sides of the fabric. After curing, the fabric may be subjected to compressive shrinking. The fabric may be made of natural or artificial cellulosic or resin-type materials.

Filed: 1961-07-26
Abstract: 995,419. Discharge lamps; electrode materials. PATENT-TREUHAND-GESELLSCHAFT FUR ELEKTRISCHE GLUHLAMPEN. July 26, 1961 [July 27, 1960], No. 27094/61. Heading H1D. An electric discharge lamp filled with metal vapour and/or rare gas and operating at a loading of more than 10<SP>4</SP>W/cm.<SP>3</SP> and at a pressure of more than one atmosphere comprises a cathode 2 and anode 3 connected to a D.C. supply to set up a basic discharge and a third electrode 4 arranged laterally of the line between the electrodes 2 and 3 and nearer to the cathode 2 and connected as an additional cathode in a circuit supplying a continuous or pulsating D.C., the electrode 4 being so dimensioned and positioned in relation to the basic discharge and the current which it carries during operation being so chosen that a discharge without cathode spot originates on it. The envelope can be of quartz glass, glass, aluminium oxide or of metal with windows. The metal envelope can form one of the electrodes, e.g. the anode. The basic discharge can be operated with relatively low power consumption and the current supplied to the third electrode can have a much higher value than that of the basic discharge. The third electrode can be in the form of a ring 7, Fig. 2, surrounding the arc of the basic discharge and in a plane at right angles to the direction of the basic discharge. The anode can be an annular electrode and can have an insulating layer on the side facing the cathode. A material which reduces the work function of the electrons and facilitates the formation of a discharge without cathode spot can be added to the material of the third electrode. The third electrode can consist of tungsten with an addition of thorium oxide or lanthanum boride, or can consist wholly or partly of thoriated tungsten, tantalum or hafnium. The third electrode can be provided with a groove facing the basic discharge which groove is filled with an activating material. The filling of the lamp can contain a material, e.g. a halogen or a halogen compound, which forms with the material of the third electrode, e.g. tungsten, a compound having a higher vapour pressure than the electrode material at the temperature prevailing in the lamp and dissociating at the high temperatures in the arc starting at the third electrode-this purifies the envelope. Magnetic displacement of the discharge can be prevented by effecting the current supply to the ring-shaped electrode 7, Fig. 2, at two oppositely arranged supply points or at several supply points arranged symmetrically, or by arranging that the conductor for the current supply to the third electrode forms outside the envelope one or several turns which lie substantially in the plane defined by the axis of the basic discharge and the direction of the current inlead to the third electrode within the envelope. The filling can be xenon or krypton at an operating pressure of 1-50 atmospheres.

Abstract: 1350784 Heat-treating steel KOBE SEISKOSHO KK [trading as KOBE STEEL Ltd] 19 April 1971 [15 April 1970] 27103/71 Heading C7A Cold - worked steel containing a grain-refining element is heated for at least 5 minutes to a temperature between that of ferrite recrystallization and A 3  to bring about recrystallization of the ferrite structure, and is then further heated to a temperature between A 3  and the austenitic grain coarsening temperature to produce a uniform austenitic structure. Prior to the above treatment the steel may be heated to above 1000 C possibly combined with hot working for at least 5 minutes to dissociate carbide nitride or oxide grain refining phases, cooled at more than 5C/minute to a temperature in the range 500-900C, heated to a temperature between 500 C and A 3  for over 5 minutes to re-precipitate those phases in finely despersed form, and then cold worked. Intermediate anneals during the latter operation are carried out below A 1 , while the final heating to the austenite range may include a carburization step. As exemplified the process is applied to steels containing by weight together with one or more of Al, Zr, Ti, V, Nb, Ta or a rare earth metal.
