Title: Improvements in and relating to spark gaps for excess voltage electrical protection devices
IPC: H01T1/00
Filed: 1934-10-03
Abstract: 434,572. Protective arrangements. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Oct. 3, 1934, Nos. 28303 and 28304. Convention dates, Oct. 3, 1933 and March 28, 1934. [Class 38 (iv)] A spark gap has at least one of its electrodes formed of a body having a central surface connected to the lead of the electrode and an outer portion connected with the central portion only by means of a portion of the body formed of poorly conductive material so as to increase the sensitivity of the gap to transient voltages. One or both of the electrodes may have a central portion 11 of good conducting material, and a surrounding mass 10 of poorly conductive material connected to the electrode spindle. The mass 10 may be of carbon, slate, silicon carbide, pressed asbestos or the like. Alternatively, the mass 10 may also be of good conducting-material, but insulated from the electrode spindle and separated from the central portion 11 by material such as badly-conducting paper, cement or the like. In a further modification the mass 10 is of insulating material covered with a surface 22 of good conducting metal which is connected to the electrode spindle by a block of resistance material 25 forming part of the electrode body. Where two or more such good conductive outer portions are provided they are connected with each other by poorly conductive material so that they are electrically in series with each other. The mass 10 is recessed at its active face so that the central member 11 is spaced therefrom in an annular recess so as to form a spark gap with the conducting material on the mass 10. The annular spark gap may be split up by one or more conducting rings 26 which may be insulated or may be connected to the electrode stem and to each other through resistance material. In all these arrangements, at normal frequency the electrostatic field is undistorted, but on the occurrence of a high frequency surge the increased capacity current causes an increased drop in the resistances so that the several faces of the electrode assume different potentials and tend to concentrate the field in the neighbourhood of the point-like central electrode. Furthermore, sparks may occur between the various parts of the electrode, so igniting the main spark.

Title: Improvements in methods and apparatus for machining moving workpieces
Inventor: SCOTT BRIAN FREDERICK
IPC: G01M1/34
Filed: 1968-06-14
Abstract: 1,268,482. Machining by laser beams. NATIONAL RESEARCH DEVELOPMENT CORP. 13 June, 1969 [14 June, 1968], No. 28378/68. Heading B3V. [Also in Division G1] A moving workpieee 13 is machined by varying the path of a laser beam so that it follows a predetermined portion of the moving workpiece 13. A rotor 13 is balanced by detecting the portion producing out of balance forces and removing the portion by the laser beam. The out of balance forces are detected first in one plane by a sensor 21 having a magnetic core 23 whose movement inside a coil 25 is proportional to the out of balance forces. Light from a strip divided into equal black and white areas carried by the rotating rotor 13 is detected by a device 27, the output of which is fed to wattmeters 29, 32 which provide the co-ordinates of the required portion of the rotor 13 to be removed. A light spot representing these co-ordinates is projected on to a screen. The outputs from the wattmeters 29, 32 are passed via amplifiers 33 34 to ganged potentiometers 35, 36, the signals from which are summed in an amplifier 37. The signal from the latter is passed to a motor 42 driving prisms 12, 19 which reflect the light from a laser 10 on to the rotor 13. Rotation of the prisms 12, 19 causes the laser beam to follow the portion of the rotor 13. A phase delay circuit 44 allows, for each revolution of the rotor 13, the laser 10 to be triggered in phase with the prisms 12, 19. A device (not shown) is coupled to an amplifier 40 to provide a light spot on a screen showing where the laser will strike the workpiece. The ganged potentiometers are adjusted until this spot is coincident with the spot indicating the position of the portion to be removed. The laser is thereby fired at the required time during each revolution of the rotor 13. When the out of balance forces detected by the sensor 21 have been reduced, out of balance forces detected by a sensor 22 are then reduced in a similar manner. The trigger module 46 includes a delay line circuit (Fig. 4, not shown). Other arrangements for reflecting or refracting the laser beam are described. The apparatus may be applied to a linearly moving workpiece.

[Class 4.] Fuselages; propelling.-In a tractor aeroplane in which the pilot's and other seats in the fuselage are in advance of the engine or engines, the seats are arranged in one or more pairs behind the propeller or propellers, the seats of each pair being disposed one on either side of the fuselage centre line. Fig. 2 shows an aeroplane having seats 2, 3 separated by a bulkhead 10 from an engine 1 which drives an airscrew 5 through a tubular shaft 6 passing between or beneath the seats. Engine 1 is surrounded by a cowl 12 having an inlet 13 and a rearwardly directed tapering outlet 14 through which the exhaust pipes may be passed. In the case of an air-cooled engine a fan is mounted in a casing 16 and driven from the engine, air being taken from scoops or openings beneath the rear end of the seating portion. Alternatively an inverted engine may be used, Fig. 4, having the cylinders projecting beneath the fuselage. The airscrew shaft is carried by a self-centring bearing housed in the fuselage nose 4 and flexible joints may be provided in shaft 6. In one form, Fig. 4, shaft 6 is enclosed in a casing 7 and is connected at one end to the engine shaft by a coupling 8 and at the other to a shaft 9 carrying the airscrew hub. The bulkhead 10 may form an engine mounting when a rotary or radial type engine is employed. When outboard engines are used, Fig. 5, the propeller shafts are carried in brackets 21, offset from the fuselage nose with or without additional supports 22. A radiator or radiators may be arranged along the sides of, or beneath, the fuselage ; in the former case a fan or blower driven from the engine is provided for the radiator. If air-cooled engines are fitted their cylinders may project above or below the planes. In all the above arrangements the fuselage nose is so shaped as to give an aerofoil contour to the fuselage.
