Title: Improvements in or relating to control arrangements for photo-electric devices in facsimile apparatus and the like
Inventor: PHILLIPS ERIC THOMAS ARTHUR
IPC: H04N1/40
Filed: 1951-10-26
Abstract: 723,786. Photo-electric control systems; copying-telegraphy. MUIRHEAD & CO., Ltd. Oct. 7, 1952 [Oct. 26, 1951], No. 25070/51. Class 40 (3). A control arrangement for the output of a photo-electric cell in a facsimile scanner or like apparatus comprises means for automatically increasing the light and/or power inputs to the cell to increase its output from a low basic level to a predetermined value in response to an initiating switch operation, and for automatically restoring the output of the cell to a basic low level in response to a further switch operation. At the beginning of transmission a start switch 7 is closed and a motor drive unit 8, brought under control of a motor supply unit 6, operates a control member 2 for the lamp-supply unit 4 and a control member 3 for the photo-cell voltage unit 5. The output from the cell 10 in respect of a reference copy 11 is fed over a connection 10a, and also to a comparator 9 in which it is compared with the voltage from a standard source 1. When the desired voltage from cell 10 is reached, an off-signal is passed from the comparator 9 to the motor supply unit 6 which discontinues the operation of the drive unit 8. At the end of transmission the unit 6 is disconnected from the comparator 9, the switch 7 is opened, a further switch 12 is closed manually or automatically and the motor drive unit 8 is operated in the reverse direction from the unit 6 so that it returns to its original position and restores members 2, 3 to furnish a basic low level in the output of the photo-cell 10. The system may be such that units 2, 3 are not operated simultaneously, and that the control unit 3 is brought into operation when the full effect of the control unit 2 is found to be inadequate.

Filed: 1938-08-26
Abstract: 517,206. Centrifugal gas cleaners. BOWDEN, A. T. Aug. 26, 1938, No. 25081. [Class 23] Apparatus for separ- -ating solid particles from gases has a central inlet 3 from which the incoming gas passes to the separating chamber 1 by a number of curved ducts 4 ... 8 which cause the gas to pass outwards and downwards. The ducts are bounded by curved ribs 9... 13 on the truncated conical part 14 or on the cover 2, and the conical part 14 is secured-to the cover by a bolt 15. The crosssectional area of the ducts decreases from the inlets to the outlets to increase the velocity of the flowing gas. The upper end of the clean gas outlet pipe 16 terminates in a non-turbulent zone beneath the conical part 14. The pipe 16 passes through a conical baffle plate 19 leaving a space 20 through which the separated solid particles drop to a discharge opening normally closed by a plug 18. In a modification the pipe 16 passes vertically through the apex of the coned base 17 of the separator and a door is provided for the removal of the solids.
Patent GB-251748-A (GB)
Abstract: 251,748. Japy, P. A. J. E. March 31, 1925. Vacuum apparatus.-In motor vehicle engines in which the fuel supply conduit is situated longitudinally of the vehicles and the fuel is drawn from a rear tank by an elevating-device, inertia - controlled means are provided for closing the conduit when variations in the speed of the vehicle tend to produce a sudden afflux of liquid. As shown in Fig. 1, a closed vessel B forms part of the fuel conduit, the fuel from the tank entering through a pipe E and passing to the elevator through a pipe S. The vessel B is provided with a clack valve C secured to a lever L carrying a mass M, the vertical plane of the lever being situated parallel to the direction of travel F of the vehicle. The valve C is normally held disengaged from the mouth of the inlet pipe E, but if the speed of the vehicle is suddenly decreased, the mass M, owing to its inertia, moves forward, thus closing the valve. The mass M may comprise a roller running on a horizontal or inclined plane and provided with an axle engaging a slot in the lower end of the lever L.

Abstract: 326,157. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 3, 1928. Hydrogenation, destructive.-In the destructive hydrogenation of liquid or pasty carbonaceous materials under pressures above 30 atmospheres injurious thickening of the. material treated, and local accumulation of asphaltic products or of the catalyst, are avoided by vigorously stirring the materials so as to ensure thorough intermixing, essentially in an up and down direction, in all parts of the apparatus where it is subjected to heat treatment, the hydrogenating gas being simultaneously introduced into the body of the liquid from a pipe by means bringing the gas into a fine state of division or into the form of fine jets. The reactants and products are preferably admitted to and removed from the reaction vessel continuously. Stirring devices in the form of worms, dredgers, gear wheel pumps and the like may be employed. In an example, a residue from the distillation of crude American mineral oil is treated with hydrogen at 200 atmospheres in the presence of a catalyst of molybdic acid and zinc oxide. The catalyst is prepared by mixing these substances in molecular proportions with an addition of 20 per cent of magnesia; this is made into a paste with water, dried, mixed with an equal amount of oil residue, and ground in a colloid mill as described in Specification 326,184. The colloid paste mixed with a further quantity of the oil residue is admitted at a' to a reaction vessel, Fig. 2, provided with a worm stirrer c<1>; hydrogen is admitted through a porous plate b<1>, and a liquid circulation is maintained by a pump e<1> and a valve chamber d'. A crude lubricating oil is produced from which 50 per cent of automobile oil is obtainable. The remaining fractions are hydrogenated further to gasoline. Suitable catalysts for the process are described in Specifications 247,582, 247,583, 247,584, 249,493, 249,501, 250,948, 251,264, 257,256, 258,272, 272,829, 272,830, 272,831, 272,835, 273,228, 274,401, 275,663. 275,664, 275,670, 276,001, 285,923, 286,678, 286,679, 286,680, 286,681, 293,719, 300,703, 307,946 and 311,251.
