Title: Improvements relating to electrical pulse generating apparatus
Inventor: SCOLES GRAHAM JOHN
IPC: H03K3/55
Filed: 1964-07-17
Abstract: 1,110,214. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 23 July, 1965 [17 July, 1964], No. 29270/64. Headings H3P and H3T. In a circuit of the kind in which a pulse forming network PFN is discharged through an inductive load MC, the termination of the current pulse is accentuated by discharging the PFN into a charged capacitor C under the control of a pair of switching devices S1, S2. As described, in a circuit for controlling a synchrotron, the PFN is resonantly charged to twice the supply voltage via inductor L1 and rectifier D and discharged via the synchrotron magnet coil MC into the charged capacitor C when thyratron S1 is triggered. The auxiliary thyratron S2 is triggered by the trigger pulse fed to S1 after a delay at least equal to one transit time of PFN. An inductor LC is included to smooth the pulse top and a linear or voltagedependent resistor R2 is provided to damp out overshoot. In Fig. 10 (not shown) the capacitor C is charged to half the supply voltage. S1, S2 may be replaced by thyristors or gate turn-off devices.

Title: Examination or inspection of rotogravure printing cylinders or the like
IPC: B41C1/18
Filed: 1973-06-21
Abstract: 1430318 Ultrasonic gauging of dimensions; monitoring facsimile engraving EUROPEAN ROTOGRAVURE ASSOCIATION 21 June 1973 29643/73 Addition to 1386867 Headings H4D and H4F A printing cylinder 1 having cavities in which ink will be deposited to form a copy of an original 3 is examined by an ultrasonic scanner 7 which determines the depths of the cavities. The original 3, which may be a negative or positive transparency around a cylinder or may be an original printing cylinder is examined by a scanning head 4. If the original is a transparency then head 4 uses a light beam to determine the tone density of the original. If the original is a printing cylinder then head 4 is an ultrasonic scanner determining the depth of the cavities similarly to scanner 7 for cylinder 1. A shaft 2 connects cylinders 3 and 1 so that corresponding areas are scanned. The signals from the scanners are fed to computers 5 and 8 where they are processed so as to be suitable for comparison in device 6. The depths of the cavities in cylinder 1 determining the amount of ink held and hence the tone intensity of the printed copy. The depth in a certain area of cylinder 1 must therefore correctly correspond to the intensity in the corresponding area of cylinder 3 if a true copy is to be obtained. Any difference is detected in device 6 and monitors 9, 10 are activated to spray ink on cylinder 1 where the depths are incorrect. The colour of the ink may indicate whether a cell is too deep or too shallow. The marked cylinder 1 can then be corrected.

Abstract: 922,720. Fluid-pressure servomotor control systems; hydraulic transmission of power. FORD MOTOR CO. Ltd. Aug. 15, 1960 [Sept. 3, 1959], No. 30063/59. Classes 69 (2) and 135. An hydraulic transmission as described in Specification 866,609, is provided with means to relieve overload. The transmission described in the above-mentioned Specification includes a pump swash-plate 23 and a motor swash-plate 24 whose angles are varied by moving cylinders 21, 22 under the control of valves 17, 18 actuated by a cable 9 which rotates a cam 11. The present invention relates to the use of non-return valves 27, 28 which open in the event of excess pressure in the transmission circuit fed to ports 19, 20, to admit fluid pressure to the ends of the control valves 17, 18, causing them to produce a resultant couple on the cam 11 to rotate this cam which allows axial movement of the valves and corresponding adjustment of the swashplates to reduce pressure in the transmission circuit. Orifices 31, 32 allow excape of fluid from the ends of the control valves. In a modification, the non-return valves are in the two lines of the pump and depending on the direction of rotation of the pump, the valve in the high-pressure line opens with excess pressure to supply fluid to a piston and cylinder device secured to the cable 9 causing direct rotation of the cam to actuate the valves 17, 18.

[Class 23] The mechanism associated with a cover-locking device for a centrifugal machine includes a pivoted member m which is rocked from its normal position by the rotating flange n<1>, if any attempt is made to release the lock while the machine is running; and this rocking prevents the mechanism from being effective. The cover b carries a bolt d pressed outwards by a spring f to engage the fixed part e on the casing a. A hand lever g is pivoted to the bolt and to one end of a rod h, the other end of which is pivoted to one arm of an angle lever supported on a fixed pivot J<1> and carrying a pin j<2> on which is supported the member m. The flange n<1> rotates with the bowl spindle c and is in close proximity to the end of the member m. When the machine is stationary and the lever g is operated to withdraw the bolt, the member m engages the disc n<1> and the pivot g<1> at the junction of the lever g and the rod h serves as a fixed fulcrum. If however, the attempt be made while the machine is running, the member m will be rocked, as shown in Fig. 3, by the disc n<1> so that the fulcrum g<1> yields while the bolt remains stationary. In a modification the control member m swings in a horizontal plane instead of a vertical plane.

Abstract: 300,266. Merck, W., Merck, K., Merck, L., Merck, W., and Merck, F., (trading as Merck, E.). Nov. 11, 1927, [Convention date]. Extracts, making. - Liquid mixtures are separated by adding a liquid or mixture of liquids having different solvent power for the different constituents, at such a temperature that a homogeneous mixture, is formed, and cooling the mixture in stages so as to precipitate the constituents fractionally. The process may be used to separate the constituents of lubricating oils, lignite tar oils or other hydrocarbons, and ethyl, propyl or other alcohol or a chlorinated hydrocarbon, such as carbon tetrachloride, may be used as the solvent liquid. In one example, 1000 cc. of mineral lubricating oil, S.G. 0.9283, is dissolved in a mixture of 500 cc. of normal propyl alcohol and 500 cc. of anhydrous ethyl alcohol by heating to 66' C. The solution is cooled successively to 61, 33 and 10‹ C., the lower layer being drawn off in each case. Fractions 1 and 2 are also cooled to 10‹ C., and the upper layers united to form fraction 4. A fifth fraction is formed from fraction 3 by expelling the solvent or by adding water.
