Abstract: 454,185. Retorts for destructive distillation. PHYSICAL CHEMISTRY RESEARCH CO., 100, West 10th Street, Wilmington, Delaware, U.S.A. Aug. 19, 1935, No. 33240. Convention date, Feb. 21. [Class 55 (i)] In the destructive distillation of solid or pasty carbonaceous materials such as schists, lignites, peats, bitumens and mixtures of oils with solid carriers, such as clay or powdered coke, in which the material passes in separate portions in a continuous manner through an externally heated chamber, the evolved gases being continuously removed in countercurrent to the travel of the material, the gaseous products from one separate portion are evacuated from the chamber after having traversed at least one neighbouring cooler portion of the charge and out of contact with the heated walls of the chamber. The material is kept in separate portions by a number of linked discs 6 arranged within a conduit 1, preferably in the form of a horizontal or oblique U, the material to be distilled being fed in at 3 and removed at the other end of the U at 5. The endless chain of discs is driven by a wheel 9 provided with radial blades 11 of radial distance apart equivalent to the spaces between the discs and contacting therewith. The apparatus is sealed to the atmosphere by immersing the ends of the retort and the driving wheel in liquid seals 19, 20. The retort is heated by combustion gases circulating through a surrounding jacket 13 in countercurrent to the material being distilled, from burners 14 arranged near the discharge end of the retort and evacuating into a chimney 15 near the inlet of the retort. Electric heating by resistances may also be used. The retort is also internally heated by the evolved gases which pass through central apertures 6‹ in the discs to off-takes 16 located nearer the inlet end of the retort. Volatiles are recovered in a condenser 18. A retort of internal diameter of 0À15-0À20 metres, length 5-6 metres and distance between the discs of 20 cms. is specified. In a modification, Fig. 6, the retort is arranged as a helix with large spirals, the axis being vertical, horizontal or oblique.

Filed: 1948-09-03
Abstract: 654,315. Saw-tooth generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 3, 1948, No. 23276. [Class 40 (vi)] In a saw-tooth generator of the Miller type an electronic charging device is connected between the anode of the Miller valve and a point of positive potential so that when the anode potential falls below a predetermined value at the end of a voltage sweep the charging device conducts and the Miller capacitor is rapidly recharged thus shortening the flyback. Fig. 2 shows a saw-tooth generator in which in the normal manner the Miller capacitor C1 effects a linearly falling voltage at the anode of valve V1, at some predetermined value of anode potential, valve V2 conducts the transformer in its anode circuit applying both a negative potential to the suppressor grid of valve V1 to render it non-conducting and a positive potential to the control grid of valve V2 to increase its conductivity. Capacitor C1 thus rapidly recharges through valve V2 and the cycle is repeated. In a modification shown in Fig. 3, a transitron connection is made by capacitor C2 so that the anode potential of valve V1 falls until the cathode current transfers from anode to screen-grid circuit the fall in screen-grid potential then applying a negative voltage to the suppressor-grid of valve V1 to render the valve non-conducting and a positive potential to the grid of valve V2 to render it conducting. The transformer in the anode circuit of valve V2 augments this action so that capacitor C1 is rapidly re-charged through valve V2.

Title: Motion picture film cassette
IPC: G03B17/26
Filed: 1974-05-24
Abstract: 1466145 Film cassettes associated with a sound transducer POLAROID CORP 24 May 1974 [28 June 1973] 23295/74 Heading B8M A film cassette, Fig. 5, of the kind housing a film strip 26 on which there is a magnetic sound track 186, Figs. 19 and 24, is characterized in that the cassette has an aperture 190 through which an external magnetic sound transducer 252 can be inserted to engage the sound track 186, stop means 300, Fig. 24, in the cassette for limiting the movement of the transducer 252 into the cassette, and support means 188 in the cassette so constructed that when the transducer 252 is engaged against the stop means 300 the support means 188 resiliently urges the sound track 186 against the transducer head 252, the whole being so arranged that the support means 188 and the transducer head 252 are capable of following any lateral or angular deviation of the film strip 26. The support means 188 carries a pair of teats 212, 212 that press the sound track 186 against the transducer head 252. As shown in Fig. 19 the support means 118 is pivoted at the upper end at 196 and carries at its lower end a pair of ears 214, 216. Lateral movement of the film 26 causes the film to engage one or other of the ears 214, 216 and so rock the support means 188, and thus the teats 212, 212 about the pivot 196. The sound transducer 252 is on a lower portion 226, Fig. 19, pivotally mounted by a pin 228 on an upper portion 224. The lower portion 226 carries upper spaced tines 244, 246 and lower spaced tines 248, 250 that can embrace the film 26. The upper part 224 of the transducer head 252 is pivoted in a plane perpendicular to the film strip 26 as well as in a plane parallel to the film strip by means of a pivot pin 230 that extends into a supporting mount 234 secured to an end wall of the pocket into which the cassette is to be inserted. The upper and lower portions 224, 226 co-operate in a compound manner permitting the transducer head 252 to follow both angular and lateral shift of the film 26 without altering the registration of the transducer 252 with respect to the sound track 186 of the film strip 26. A spring 280, Fig. 5, biases the upper portion 224, and thus the transducer head 252, towards the film 26. After the film has been exposed by winding it from reel 51 to reel 63, the film is wound back on to reel 51 and in doing so the film is automatically subjected to a photo-finishing process by contacting the film with a composition 96 that forms a finished transparency from the latent image or images formed on the film during its exposure. For this purpose the film strip carries a detent 42, Fig. 4 (not shown), that automatically causes the contents 96 of a reservoir 83 to be released on to the film strip as it is rewound on to the reel 51. The apparatus includes a driven roll 57 that is contacted by a drive roll 274 when the transducer head 52 is inserted into the opening 190; and a dancer roller 56 that serves to smooth out any tension variations that may occur as the film motion starts and stops.
