Title: Improvements in the preparation of catalysts for use in the manufacture, by destructive hydrogenation, of hydrocarbons from carbonaceous materials
IPC: C10G1/06
Filed: 1930-02-15
Abstract: <PICT:0348690/III/1> Carbonaceous materials are destructively hydrogenated at 250 DEG  C. or higher and under a pressure of at least 20 atmospheres in the presence of catalysts obtained by treating oxides of metals of group 2 and 6 with volatile sulphur, selenium, or tellurium compounds, such as hydrogen sulphide, carbon bisulphide, mercaptans, thiophene, alkyl sulphur compounds, thioethers, hydrogen selenide, or hydrogen telluride, at elevated temperatures, such as 400-500 DEG  C., in the presence of hydrogen and in the absence of hydrocarbons which are not gaseous under normal conditions.  Examples of suitable oxide mixtures are given.  The activity of the catalysts may be maintained by adding a definite concentration of a volatile compound of the negative element of the catalyst to the hydrogenating gas.  Apparatus for a single stage, continuous process consists of a reactor 8 to which a coal-oil mixture is supplied from a mixer 2 through a preheater 6; heat is supplied by electric resistances 10, and the catalyst is carried on rotating stirrers 11.  Preheated hydrogen enters through a nozzle 15. Volatile products leaving at 16 are separated in the usual manner, the hydrogen being re-cycled.  In a two-stage process, heavy oil withdrawn from the base of the reactor is further treated in a second vessel.  Examples of the destructive hydrogenation of various oils are given.  The catalysts may also be used for cracking, and for the refining of lubricating oils, illuminating oils, and benzines.

Title: Hydraulically driven turning device for reversible ploughs
IPC: A01B3/421
Filed: 1970-02-04
Abstract: 1,269,739. Hydraulic turning device for reversible ploughs. V. LEMKEN [trading as PFLUGFABRIK LEMKEN K.G.], 4 Feb., 1970 [13 Feb., 1969], No. 5376/70. Heading A1B. A device for turning a plough comprises a hydraulic cylinder 12 articulatedly mounted on the plough front chassis which carries the turning shaft 6, the piston rod 13 being pivoted at 15 to a crank arm 7 of the turning shaft. The cylinder is arranged to contact a stop connected with the piston rod at each end position of the plough, and provision is made for adjusting the angular position of the turning shaft relative to the plough chassis in the end positions. The centre of gravity of the crank arm is at the eccentric position S and, in the position shown in Fig. 1, the crank is prevented from rotating due to this eccentricity by a roller stop 17 attached to the piston rod by link 16 and contacting the cylinder base. When the stop is taken out of such contact under the action of the lever 16a the crank arm 8 swings downwards causing the piston rod to enter further into the cylinder and the crank arm 7 to rise to the position shown in chain lines, where it is prevented from falling back by a pawl 18 entering a groove 19 in the end of the crank arm. Pressure fluid is then applied to the cylinder via pipe 21 to complete the motion to the other end position where stop 17 is reapplied. The cylinder is pivoted at 11 on a member 10 which can slide vertically in the chassis by turning screw 9. The resultant variation in angular position of the crank arm is alternatively achieved by having a series of positions on the crank arm at which the piston rod can be selectively pivoted, as in Fig. 4. Alternatively the piston rod may be of variable length. The stop arrangement of Figs. 4 and 6 has a pin engaging a slot in the piston 14 and being displaced by the pressure of fluid introduced into the cylinder at 21. The pin is also displaceable by a manual linkage 29 and by the action of the tapered bottom of the piston on the end of the pin when the piston descends.

Title: Improvements in or relating to a regulating device for universal motors
IPC: H02P7/295
Filed: 1967-02-03
Abstract: 1,128,434. Automatic speed control, MEFINA S.A. Feb.3, 1967 [Feb.10, 1966], No. 5450/67. Heading G3R. [Also in Division H2] During a positive half-cycle of source a, b, a capacitor C1 is charged from terminal b at a rate determined by the adjustment of variable resistor R2, which is shunted by fixed resistor R1, until Zener diode D2 breaks down to trigger thyristor T in series with motor M. During the following negative half-cycle, the resistor R1 only is connected in series with the capacitor C1, due to the blocking effect of a diode D1, and the capacitor is partially discharged through the resistor R1 and through a tachometer generator G. When the motor speed and tachometer voltage have high values, the rate of discharge of the capacitor is increased, so delaying the firing-point of the thyristor during the next positive alternation of the supply voltage. This decreases the mean current fed to the motor. In a similar manner, an increase in motor load causes a forward shift of the point of ignition of the thyristor, whereby the motor current is increased. In another arrangement, the tachometer generator is connected to a bridge rectifier shunted by a diode which conducts at a predetermined voltage. The feedback effect of the generator G is thus omitted over the high-speed range. In a further embodi - ment, a transistor is controlled by the tachometer generator to regulate the rate of discharge of the capacitor.

Filed: 1938-02-23
Abstract: 515,421. Photographic processes. ELVEGARD, E. R. Feb. 23,1938, No. 5780. [Class 98 (ii)] A layer of cellulose hydrate is made photo-' graphically light-sensitive by immersing it in a solution of a silver compound, e.g., silver nitrate, arid then immersing it in a solution containing free halogen or free hydro-halogen, e.g., bromine, which may be obtained from potassium bromide and nitric acid or may be mixed with potassium bromide, or hydrobromic acid. The process completely converts the soluble silver compounds to prevent future fogging. In a modified process. the layer of cellulose hydrate forms a permeable partition between .two compartments of a container containing the two solutions. An electric current may be used for facilitating the passage of the solutions into the layer. The light sensitive layer may be hyper-sensitized by subjecting the layer to heat or treating it with a. solution of ammonia or an organic amine or by adding to it a sulphur-containing sensitizer, e.g., thiosinamine. The layer may be colour-sensitized with cyanines or phthaleins. Specifications 503,845 and 515,420 are referred to.
