Title: Improvements in or relating to apparatus for examining moving articles
Inventor: LUBSZYNSKI HANS GERHARD
IPC: G01N23/04
Filed: 1957-10-05
Abstract: 902,564. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 1, 1958 [Oct. 5, 1957], No. 31230/57. Class 40 (3). [Also in Group XX] Apparatus for examining a moving article comprises a charge storage device including a charge storage electrode, means for directing invisible radiant energy on to an inspection field through which the article moves, image projecting means for causing the energy which passes through said field to form a focused image on and so charge said electrode, and means for scanning the charge image so formed to generate a signal representative of said image, the image projecting means including a movable image deflecting means arranged to move so that when the article is moved across the inspection field at a steady velocity the image formed on the electrode is stationary or relatively slowly moving during alternate intervals and relatively rapidly moving during the intervening intervals. As shown, the web 1, e.g. of metal from a rolling mill, is examined with a beam of X-rays from the tube 3 and a moving image is formed on a fluorescent screen 4, this image by means of lens 7 and rotating optical compensating reflecting polygon being presented as a succession of stationary frames on a television pick-up tube 8 of the Vidicon type having a photo-conductive storage electrode, the resulting image being scanned and displayed on a viewing tube 10 having a long decay screen. In another arrangement for examining photographic film, the radiation source employed is an infra-red lamp and the transmitted radiation is reflected directly by the rotating polygon. If the pick-up is a tube of insufficient resolution for the details to be observed, the field may be divided optically into two or more parts and a separate pick-up tube used for each, the signals derived from these tubes being used to operate a single viewing tube or separate viewing tubes. Instead of feeding the video signals to a viewing tube, they may be used to modulate the electron writing beam of a tube having a storage electrode and the charges subsequently reconverted into electrical signals for operating a viewing tube by scanning the electrode with a reading beam or by flooding the storage electrode with electrons, the resulting modulated flood being projected on to a fluorescent screen.

Title: Improvements in or relating to aqueous dispersions of pigmented alkyd resins
Inventor: WALDIE WILLIAM ALLSHIRE
IPC: C09D167/08
Filed: 1950-12-27
Abstract: A pigmented alkyd resin emulsion for coating purposes is made by reacting glycerol with phthalic or maleic acid or anhydride and during the condensation mixing in and reacting at approximately 450 DEG  F. a fatty acid-coated pigment, the pigmented resin, after cooling, being emulsified in an aqueous ammoniacal mixture of casein and ethylene glycol mono-ethyl ether.  The fatty acid coated pigment may be prepared by saponifying an oil or fatty oil acid, e.g. with caustic soda, and adding the pigment, e.g. lithopone, carbon black, titanium oxide, iron oxide, the chromium greens and ultramarine blue, suspended in water.  The suspension is then acidified, e.g. with acetic acid or N/10 hydrochloric acid to precipitate the fatty acid. The pigments should not be reactive with the fatty acid or resin-forming materials.  The resin may be further modified with fatty oils.  In an example, 22 lb of linseed oil are saponified by boiling with caustic soda in 20 gallons of water.  40 lb. of lithophone are added in 10 gallons of water and boiling continued for 1 hour.  Acetic acid is added to precipitate the fatty acid which is separated from the water. 23 lb. of phthalic anhydride are heated with 11.7 lb. of glycerol to 400 DEG  F. until homogeneous.  The pigmented fatty acid is then added and the mix heated to 450 DEG  F. until reacted to the desired degree whereupon 18 lb. of heat-bodied linseed oil is added and the resulting mix heated to 500 DEG  F. until homogeneous.  After cooling to 250 DEG  F. a mixture of 12 lb. ethylene glycol monoethyl ether, 4 1/2 lb. casein, 3/8 gallon ammonia water and 6 gallons water are added and the whole emulsified.

Moulding sound-amplifying horns.-A soundamplifying horn comprises a reinforcing casing or member housing a moulded body provided with a sound passage therethrough; the body is preferably reinforced also by an embedded element disposed in close proximity to the sound passage. As shown in Figs. 9 and 11, a cylindrical sheet-metal casing 22 houses a moulded body 27 which is cast within the casing. The body is formed with a tapered sound passage 45 surrounded by a wall 59 the turns of which are connected by a web 60. A nipple 47 is embedded in the body 27 at the entrance to the passage 45 and is threaded at 48 to receive a reproducing unit 52, a foraminous disc 55 being interposed to exclude dust &c. The casing 22 is supported by a saddle 31 carried by a base 21, the parts being screwed together by a bolt passed through holes in the members 21, 31 22 and engaging a nut embedded in the body 27. The front of the casing 22 is closed by a foraminous member 38 and the back by a sheet metal cover 42. In moulding the body, a casing 22 is placed on a bottom die 73, Fig. 5, and a tapered, gelatine core 64, wound helically with a spiral metal reinforcement 62, is inserted and located by a flange 68 on the recessed head of the core engaging a part 87 of the die and by inserting the narrow end of the core into the flared end 57 of a nipple 47 which is carried on a tubular member 92 passing through a sleeve 96 in the die 73.
