Abstract: 924,567. Electric Integrators. COMMUNICATIONS PATENTS Ltd. Sept. 5, 1961 [Sept. 15, 1960], No. 31778/60. Class 37. In an integrator system having input terminals 11, 12 supplied with rate input signals # and - # representative of the rate of change of an angular position #, the first input terminal is connected to a first input terminal of a servo amplifier 1 to supply the rate signal # thereto, the servo amplifier having second, third and fourth input terminals connected respectively to receive second, third and fourth input signals, and also having an output terminal connected to supply the servo amplifier output signal to drive a servomotor 2. The output shaft 3 of the said servomotor drives a positive feedback signal generator G, which supplies the second input to the servo amplifier, and two potentiometers 7 and 8 through a speed reduction gear 5. The system has means including potentiometer 8 for providing a derived signal corresponding to the sine of the integral of the said rate signal and means including the potentiometer 7 for providing a derived signal corresponding to minus the sine of the integral of the said rate signal, the derived signals being supplied to the servo amplifier as the third and fourth input signals. The means for providing a derived signal corresponding to the sine of the integral of the said rate signal consists of the cosine law potentiometer 8, which has inputs corresponding to the positive and negative values of the rate signal,  #, and an output - # cos # which is applied to a Miller integrator 13 followed by an inverting amplifier 14. The means for providing a derived signal corresponding to minus the sine of the integral of the rate signal is a sine law potentiometer with inputs from the positive and negative poles of a direct-current supply. By means of a rotary switch 9 driven by the shaft from the servo motor the relay A is caused to operate for angles of # between 90 degrees through 180 degrees to 270 degrees, altering the positions of contacts A1, A2, and A3 so that the polarities of both derived signals may be reversed. The invention is suitable for use as an integrator for pitch or roll angles for a flight simulator, the servo acting as an integrating servo operating on command of the input signal #. Trigonometric outputs may be obtained from amplifiers 13 and 14.

Title: Improvements in mechanism for packaging cigarettes and similar articles
IPC: B65B19/10
Filed: 1922-11-21
Abstract: 211,566. Thornton, A. A., (Comas Cigarette Machine Co.). Nov. 21, 1922. Packeting cigarettes and like articles in receptacles. - Relates to machines for packeting cigarettes and articles of similar cylindrical shape and of the kind in which the cigarettes &c. are fed between partitions from which a plunger removes a charge, one article being withheld in each alternate row, so that, for instance, when twenty cigarettes are to be delivered, the rows contain seven, six, and seven cigarettes respectively. According to the invention, parts of the partitions are in zig-zag or herringbone formation and the articles are ejected therefrom by zig-zag or herringbone plungers. As shown, the cigarettes C, Fig. 1, are placed in a hopper A and fall between vertical partitions 1 which are of zig-zag form at the bottom, and cause the cigarettes to be disposed in staggered rows. A multiple plunger 4, shown in croos-sections in Fig. 2' and in Fig. 10, advances between the partitions and expels seven, six, and seven cigarettes respectively from the three bottom rows, the cigarette C', Fig. 1, being arrested by a guard 7 and the plunger being recessed at 6. The twenty cigarettes are thrust through a convergent passage 8, Fig. 10, and into the path of a transferring plunger 10, Fig. 6, on a cross-head 11. The other side of the batch is engaged by fingers 12<1> depending from a collar 13 loosely mounted on a rod 14. In the left hand position, the fingers 12<1> are separated rather more widely from the transferring plunger 10 than is shown, owing to the slot 15 in which they work ending at 17. The plunger 10 makes an initial slight movement towards the fingers, compressing the batch, and then the plunger and fingers travel in unison until the collar 13 has cleared the end 25 of a switch piece 22. A spring 26 then causes the rod 14 to swing upwards about a pivot 14<1> and to lift the fingers 12<1> out of action, the cigarettes then being supported on the right, Fig. 6, by a spring- pressed sliding head 19. The plunger 10 and the head 19 are so shaped as to retain the articles in the relative position in which they left the hopper. An inclined wall 36 causes the fingers to be depressed on the return movement of the transferring plunger. The batch is now in position between the plates 33 of an open-sided plunger, which carries it into folding mechanism.

Title: Methods of preparing hydrofining catalysts and processes for using same
IPC: B01J21/12
Filed: 1955-11-08
Abstract: Catalyst suitable for hydrofining petroleum hydrocarbons is prepared by reacting together sodium aluminate, aluminium sulphate, and sodium silicate in an aqueous medium maintained at a pH between 9 and 10, filtering, washing, drying, and heating the resultant precipitate of silica-alumina, and incorporating an active hydrofining catalyst with the silicaalumina.  Suitable hydrofining catalysts are cobalt molybdate, mixtures of cobalt oxide and molybdenum oxide, and sulphides such as molybdenum sulphide or nickel-tungsten sulphide. The silica-alumina, which preferably contains 1-5 per cent by weight of silica, may be impregnated with 5-20 per cent by weight of cobalt molybdate by mixing with an aqueous solution of a cobalt salt and a molybdenum salt and heating to remove water.  Heating oils boiling in the range 400-1100 DEG  F. may be treated with hydrogen in the presence of the catalyst under mild hydroforming conditions, e.g. a temperature of 400-700 DEG  F., a pressure of 50-250 p.s.i. and a feed rate of 1-16 volumes of liquid per volume of catalyst per hour. The hydrogen consumption is less than 60 standard cubic feet per barrel of oil and the reduction in sulphur content may be as little as 20 per cent.  The carbon residue of the oil is reduced and the product when mixed with untreated heating oil provides a blend which has a carbon residue value lower than expected.
