Title: Improved arrangement for locating lightning strokes in the vicinity of overhead lines
Inventor: GRAFF-BAKER WILLIAM SEBASTIAN
IPC: G01R31/08
Filed: 1961-07-06
Abstract: 936,216. Measuring transient voltages; time intervals; testing for faults. ASSOCIATED ELECTRIC INDUSTRIES Ltd. July 6, 1962 [July 6, 1961], No. 24494/61. Class 37. Apparatus determining location of a lightning stroke in the vicinity of an overhead line relatively to two stations thereon comprises means transmitting reference signals along the line at known regular time intervals and receivers responsive to arrival of such signals at the two stations and to transients in the line due to a lightning stroke; there being provided means to measure at each station the time relationship between the arrivals of the transient and reference signals. In Fig. 1, timing receivers 1, 2 are connected to the ends of a line 3 of length 2 and generator 4 emits timed reference signals into the line at receiver 1. A lightning stroke occurring at point A distant x from receiver 1 and at time tA generates transients travelling to receivers 1, 2 where they arrive at time displacements t 1  and t 2  (measured by the receivers) from the immediately preceding reference signals (Fig. 2) whose time difference at receivers 1, 2 is L -where V is the propagation velocity in the V line and the timing devices are reset on receipt of each subsequent reference pulse. It is shown V that x = -[T- (t 2  - t 1 )] where T is the time 2 interval between reference pulses. The receivers are sensitive only to the specific pulse generator signals, e.g. short oscillation trains of fixed frequency or pulse groups of characteristic duration or spacing, and the resetting circuits are provided with an auto following time gate, for protection against interference from spurious signals. The time interval between successive reference pulses is fixed in excess of twice the transit time of the line to prevent response to reflected pulses. The timing receiver 2 may be synchronized with 1 by a continuous central signal transmitted over the line from a common standard or the reference and standard signals may be provided by a continuous oscillation sawtooth frequency modulated at a period in excess of the transit time; the instantaneous frequencies at the respective ends of the line coincident with the lightning transients providing a measure of their arrival times. The reference signal may be transmitted by separate line or radio link, and the timing receivers may operate with a threshold excluding unwanted transients. Means may be provided for recording transient arrival times together with clock time, e.g. whenever a circuitbreaker trips in response to a lightning stroke ; the recordings being thereafter analysed to determine the location of each stroke of the recorded series.

Title: Improvements in and relating to suction chucks
IPC: B25B11/00
Filed: 1945-09-24
Abstract: 604,606. Suction chucks. ERIKSSON, E. O. Sept. 24, 1945, No. 24728. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 23, 1946.] [Class 60] In a suction chuck, for lathes and other machine tools, having a member spring-pressed in a direction to cause the reduction of pressure necessary to hold the work, movement of the member in the opposite direction against the spring pressure is effected by fluid pressure. The work-receiving plate 3 has a duct 5 leading to the interior of bellows 8 connected to the plate 3 and to a piston 7 urged rearwardly by a spring 9. When compressed air is admitted to the rear face of the piston, this is moved forwardly against the spring pressure to expel air from the bellows through the duct 5; air is also expelled through the duct 10. The work is then placed in position and the rear face of the piston is connected to atmosphere. The spring 9 then urges the piston rearwardly creating the necessary suction to retain the work. The bellows 8 preferably comprises metal discs having a small central hole and welded together alternately at their outer and inner edges. The bellows may be omitted, the piston then being provided with packings between it and the body of the chuck; the duct 10 is also omitted. A packing ring 11 of rubber or other suitable material is inserted in a recess in the work-receiving plate 3; a number of concentric recesses may be provided, a packing ring being inserted in the recess appropriate for the size of the article to be chucked. For holding annular objects, the disc 3 has two concentric recesses with packing rings and the suction duct communicates with the annular space between the recesses. For holding objects with an irregular surface, the disc 3 may have a correspondingly shaped contact surface. The Specification as open to inspection under Sect. 91 states that the forward movement of the piston 7 against the spring pressure may be effected mechanically, electrically or electromagnetically. Alternatively, the disc 7 may be fixed to the body 1, and the disc 3 moved axially by pressing the work against it; the space between the discs 3 and 7 communicates with the atmosphere through a check valve. Alternatively, the piston 7 and bellows 8 may be omitted, the duct 5 communicating directly with a source of vacuum. This subject-matter does not appear in the Specification as accepted.

Abstract: 707,378. Photomechanical printing foils. KALLE & CO. AKT.-GES. Sept. 29, 1949 [Oct. 1, 1948], No. 25087/49. Class 98(2) A foil comprising a base having a hydrophilic surface and a coating of light sensitive diazo compound which becomes oleophilic under the action of light thereon, such as the diazo compounds described in Specification 697,521, is exposed to a light image and then provided with a water-soluble film-like coating. After this the foil in a wet or dry state may be freely' exposed to light. This produces a permanent fixing of the image, and on removal of the film-like coating the parts of the original light sensitive coating which were exposed to light take greasy ink in the presence of water, while those of the diazo compound which was undecomposed in the initial exposure, but decomposed in the subsequent free exposure, do not take greasy ink; the conditions required for printing are thus provided. In Example 1 a superficially saponified cellulose acetate foil is swabbed with an aqueous solution of the zinc chloride double salt of the compound produced by condensing the sulphate of diazo-diphenylamine with paraformaldehyde, exposed under a negative, brushed with an aqueous solution of albumen, dried, and then exposed to light to fix the preformed image. In Example 2 a parchment paper sheet is brushed with an aqueous solution of the sulphonate of the diazo compound of 4-amino-1-(N-2:3:4:6-tetrachlorobenzyl)-aminobenzene, exposed under a negative, subsequently smeared with an aqueous dextrine solution and while moist exposed to light without the negative, after which it is insensitive to the further action of light. Other substances for use in the water-soluble film-like coating are described.
