Filed: 1932-11-04
Abstract: 406,807. Arc-rupturing in switches; oil-break switches. PAILIN, Ltd., F., and PAILIN, G., Buckley Street, Higher Openshaw, Manchester. Nov. 4, 1932, No. 31111. [Class 38 (v).] Automatic circuit-breakers.-Arcing is suppressed by means of a combustible body, such as gunpowder, which upon ignition develops with extreme rapidity a large volume of gas which is caused to force an oil blast across each arc gap. Ignition may be effected by means of a current obtained directly or indirectly from the controlled circuit, or by other than electrical means controlled by the circuit. In a three-phase arrangement, each phase has a combustible body and all three are simultaneously ignited by relay means on an overload occurring in any phase, either at the moment of opening or immediately beforehand. The movable electrode a passes through, so as to obstruct, a passage b leading to a pipe c, at the head of which is a chamber containing an explosive capsule e adapted to be ignited by current from a lead f. When the capsule is ignited, the pressure of the generated gas acts on a lever j, k to release the movable electrode a and also on the surface of the oil in c, so driving the oil across the arc.

Abstract: 347,090. Controlling variable-speed gearing. MAYBACH MOTORENBAU GES., Friedrichshafen-on-Bodensee, Wurtemberg, Germany. Oct. 24, 1930, No. 31959. Convention date, Oct. 25, 1929. [Class 80 (ii).] Means for changing speed by vacuum upon a vehicle is based on the knowledge that it is advantageous to use a source of constant vacuum in changing up, and to use the variable vacuum in the motor intake in changing down. An over-driving auxiliary two-speed gear, 3, 6, 7, 4 is shown operated by a double clutch 8 sliding-on driving-shaft 1, and having teeth with bevelled ends for speed-equalizing. Levers 14, 16 are separately pivoted at 13 and connected by a spring 15 so that when lever 16 is moved over by piston 19, when the dead-centre is passed, the spring shoots the clutch right over. A control cock 23 is shown connecting the rear end of cylinder 20 to engine intake 25, but it can alternatively connect the forward end of the cylinder to a chamber 29 maintained in vacuum by the engine with the aid of a one-way valve 31, 33 being the fuel supply. In order to change from the direct drive shown, to over-drive, the cock 23 is turned from a handle 37 to its other position to connect pipe 22 to chamber 29. Piston 19 and lever 16 move to the left, but spring 15 cannot move clutch 8 until the load has been removed by a closing of the throttle. There is no operation of the main clutch. To return to direct drive, the handle 37 is returned to bring cock 23 to the position shown, connecting pipe 21 to intake 25. The throttle is again closed. The latter operation produces sufficient vacuum at 25 to move piston 19, but the direction of torque on the clutch 8 has reversed. On reopening the throttle, the grip on the clutch 8 is released so that spring 15 can effect the change.

Abstract: 1,194,022. Electron microscopes. SIEMENS A.G. 12 July, 1967 [13 July, 1966], No. 31967/67. Heading H1D. In an electron microscope in which the object is examined by use of phase contrast effects, the " space frequency" components of the image are analyzed on the storage signal plate of a camera tube to produce signals for automatically adjusting the setting of the objective lens to a predetermined focus. A series of focusing settings is determined from a set of theoretically derived curves relating " defocusing distance " to " space frequency " wavelength for maximum contrast. In the arrangement shown where 2 is the object plane, 1 the objective lens and 6 a luminescent screen, the image is picked up in camera tube 9 and an output signal containing frequency components corresponding to the " space frequency " components of the image is fed via amplifier 14 to a frequency selector circuit 15. The lens excitation is controlled by a servomotor 17 which is stopped when a command control signal corresponding to a predetermined " space frequency spectrum " is received at the relay 17a. A stigmator 4 may also be adjusted by a similar system utilizing the camera tube 8 and the frequency selector circuit 15. For this adjustment the scanning pattern in the camera tube is rotated by means of rotary field generator 13 until a predetermined frequency component of the output signal from the camera tube has a constant amplitude. Preferably the object carrier foil rather than an object to be examined is used for the adjustment of the focusing. The objective lens may be electromagnetic or electrostatic and the stigmator is preferably electromagnetic. One or more phase correcting diaphragms may be used in the lens system.
