A winding machine has a member which, on yarn breakage, forms a loop in the yarn extending between the supply bobbin and a clamp and then allows a part of the loop to enter a suction tube. Winding stops when a yarn breaks and, if the break occurs between the brake disc 13 and the take-up bobbin a, the portion r of yarn extending between the supply bobbin d and the brake disc 13 is acted upon by a plate 26 on a pivoted arm 25. The arm 25 is so driven by a cam that it moves slowly or stops momentarily when passing the suction nozzle 23, allowing part of the yarn that has been drawn off the supply bobbin d to enter the nozzle. As the arm 25 passes the nozzle 23, the yarn brake 13 and a clearer are opened, whereupon the two ends of yarn are brought together and knotted. The clearer consists of a clamping member 9, Fig. 5, pressed against a plate 5 and the yarn brake includes a disc 13 spring-pressed against the plate 5. Cam mechanism is arranged to bring about simultaneous separation from the plate of the member 9 and disc 13.

Title: An improved method of, and apparatus for, cleaning and regenerating films
IPC: G03D15/00
Filed: 1947-12-22
Abstract: 656,529. Regenerating kinematographic films. JIROUCH, A. Dec. 22, 1947, No. 33827. Convention date, Aug. 9, 1945. [Class 98 (ii)] Damaged kinematographic and like films are regenerated by applying a liquid softening or swelling agent at a controlled rate to the film surface, which is subjected to a mechanical smoothing action, e.g. by a roller, applying at a controlled rate a liquid coagulating agent to the support surface or a liquid dehydrating or hardening or both dehydrating and hardening agent to the emulsion surface, and removing the applied agents by evaporation. The softening agent for the emulsion surface may be an aqueous solution of ethylene chlorhydrin, or a mixture of alcohol or acetone with glycerol and water, and ammonia, alcoholic caustic soda, or formic acid, and trichlorethylene may be added. A mixture of acetone, ethylene chlorhydrin, and toluene may also be used. The softening agent for the support surface may be a mixture of alcohol, amyl acetate, and acetone, or a mixture of ethyl acetate, methylene chloride, and acetone with camphor, triacetin, or a phthalic ester. Formic acid may also be added. Gelatin, celluloid, or cellulose acetate may be added to the softening bath. The coagulating bath may contain methyl alcohol or methylene chloride, and optionally formaldehyde, amyl alcohol, or ethyl lactate may be added. The bath may be cooled to 0‹ C. or less. In example 1, the emulsion side of a film is treated with an aqueous solution of ammonia and ethylene chlorhydrin, which may contain gelatin, and the film is then treated in a cooled mixture of methyl alcohol and methylene chloride. In example 2, the support side of a film is treated with a mixture of ethyl acetate, methylene chloride, acetate, diacetone alcohol, and triacetin or dibutyl phthalate, and is then treated with a mixture of ethyl lactate, methylene chloride, acetone, amyl alcohol, and celluloid. The apparatus comprises two agent-applying rollers 1, 1, preferably of glass with a roughened surface, driven by an electric motor 5, having a revolution indicator 6. The film is held against rollers 1 by adjustable rollers 3, and the agents are applied to the rollers 1 by spraying nozzles 2, the softening agent being applied to the first roller and the hardening agent to the second. The speed and sense of rotation of the rollers 1 is controlled and variable.

Title: Illuminating system for photographic printers and enlargers
IPC: G03B27/54
Filed: 1969-07-07
Abstract: 1,215,117. Photographic illuminating apparatus. BERKEY PHOTO Inc. July 7, 1969 [Dec. 20, 1968], No.34142/69. Heading G2A. [Also in Division F4] An illuminating system for a negative or transparency 17 comprises, symmetrically in line along the optical axis 10 of a lens 18 which images the illuminated transparency on to photo-sensitive material 19, a reflector 12 formed from part of an elliptical surface of revolution and having a specularly reflecting interior surface; a light source 11 at one focus of the reflector 12; an aperture reducer 20; a hollow part sphere 15 having a diffusely reflecting white interior surface, a small light entrance window 13 adjacent one end of the reducer 12, and a larger light exit window 16 adjacent the transparency 17; and a light distributer 14 constituted by a pyramid having a polygonal base, a specularly reflecting exterior surface, and its apex pointed towards the window 13. The light distributer 14 distributes light entering the window 13, and prevents light from passing straight through the part sphere, thereby preventing streaking of the photo-sensitive material 19. The aperture reducer 20 allows of minimizing the size of the window 13 so as to avoid a shadow appearing in the exit window 16, particularly when the part sphere 15 is small for illuminating small negatives. The aperture reducer 20 made from a clear transparent material, e.g. glass, having an index of refraction greater than unity. Preferably the reflector 12 is replaced by a smaller part elliptical reflector 40, extending to the rear of focal point F 1 , and combined with a part spherical, specular reflector 41 centred on F 1  and in front of it. This arrangement ensures that more light is reflected through the aperture reducer 20 without escaping laterally. The shape of the aperture reducer 20 may also be altered, a preferred form being shown in Fig. 18, and the reducer 20 and part sphere 15 brought nearer the light 11. The coaction of the members 20, 14 may produce another light loss by rays being reflected back into the reducer 20 by the distributer 14. To prevent this, the distributer is preferably formed as shown in Fig. 18. Finally, the shape of the partsphere 15 may be altered, by making the exit aperture 16 only slightly larger than the negative to be illuminated, and then replacing the lower portion by planes intersecting the top, spherical portion, and the vertices of the exit aperture 16. One such shape is shown in Fig. 18, but others (Figs. 9a-17b, (not shown) are also described.

Title: Shaped molecular sieve bodies and manufacture thereof
IPC: B01J20/18
Filed: 1961-09-25
Abstract: A shaped porous crystalline zeolitic molecular sieve adsorbent body is produced by mixing a zeolitic molecular sieve with 1-40% of a clay mineral binder, granulating said mixture to granular of a size such that they will pass through a screen with square openings 2.4 mm. on a side and be retained on a screen with openings 0.30 mm. on side, either before or after an initial heating step, whereupon the mixture is heated at a temperature sufficiently high to dry the clay mineral binder, bind the mixture and activate the molecular sieve, sodium silicate and water are added to the above mixture in a quantity such that the total silicate content of the porous molecular sieve body thus produced is between 9 and 25% by weight and the total moisture content is between 12 and 25% by weight.  The sodium silicate, water and granulated molecular sieve, clay binder mixture are then mixed to form a free flowing blend of uniformly distributed molecular sieve particles in a sodium silicate matrix, which is preferably preheated to 50-70 DEG  C. before shaping the blend under pressure and firing at temperatures between 350-650 DEG  C. Preferably the sodium silicate is added partly dry and partly as an aqueous solution, in which the weight ratio of the sodium silicate powder to the sodium silicate contained in the solution is in the range of from 1 : 3 to 3 : 1.  Prior to firing it is advantageous to hydrate the shaped product by exposure to water-saturated air, or saturated steam, or by spraying the outer surfaces of the article with sodium silicate solution, or momentarily immersing the article in sodium silicate solution. Suitable clays for use in the process are attapulgite, kaolin, sepiolite, polygarskite, kaolinite, plastic ball clays, clays of the attapulgite, kaolin or bentonite type, bentonite, montmorillionite, illite and chlorite.  Specified zeolites are: erionite, chabazite, analcite, faujasite, clinoptilolite, mordenite and synthetic zeolites A, T, X and Y.  Specifications 777,232, 777,233, 827,043, 909,266, 912,936 and 972,831 are referred to.

Title: Reactor assembly to reduce automotove emissions from an internal combustion engine
IPC: F01N13/04
Filed: 1971-07-21
Abstract: 1360433 Treating I C engine exhaust ESSO RESEARCH & ENG CO 21 July 1971 [24 Aug 1970] 34165/71 Heading F1B An exhaust gas reactor comprises opposed circular end-walls 41, 42, Fig. 2 and a peripheral wall 21 which define a circular reaction chamber, an inner wall dividing the reaction chamber into an outer annular chamber and an inner circular chamber which communicates directly with an exhaust outlet 43, an exhaust inlet 23 directing exhaust tangentially to the peripheral wall and an aperture in the inner wall being so located that some of the exhaust gas will circulate past the inner wall aperture to mix with exhaust gas entering the outer chamber. In operation additional air from manifold 30, Fig. 1 is introduced through lines 32, 35 into the exhaust gases flowing to the torus. Inlet manifold vacuum holds valve 82 open to permit exhaust gas recycling through a line 84 which includes a cooler 85. At intermediate positions of throttle valve 73 a valve 86 seals a line 87 to prevent air bleed to valve 82 which would close the latter. With a fully open throttle, valve 86 is in the full-line position permitting air to bleed through port 88 to prevent vacuum on valve 88 which is thus closed to prevent any exhaust gas recycling. Recycling is also prevented when throttle 73 is closed or choke valve 72 is closed. In order to prevent excessive temperatures in reactor 21 at high speeds pressure upstream of muffler 50 is transmitted to diaphragm valve 101 which diverts air from the pump 31 to the inlet line thereby leaning-out the mixture. Air, heated by the reactor, is drawn through coil 106 causing opening of choke valve 72 to lean-out the mixture to reduce reactor temperatures in modes other than high speed. The exhaust gas inlets to the torus includes flameholders 60, 61, 62, Fig. 2.
