Title: Improvements in and relating to systems of electric power transmission
IPC: B60L7/12
Filed: 1919-04-02
Abstract: 145,881. British Thomson - Houston Co., (General Electric Co.). April 2, 1919. Systems for continuous-current motors only.- The motoring and braking torque of a compoundwound motor, which also runs regeneratively, are automatically maintained constant at various settings depending upon the position of the controller. A torque relay is used, and consists of a moving coil 7 in shunt to the series field 4 and therefore carrying a current proportional to the armature current, and stationary coils 8, 9 carrying current proportional to that in the series and shunt fields. A reactance 40 is included in the circuit of the coil 7 in order that this circuit may have the same inductance as the series field. The moving coil carries a contact 10 normally lying between two sets of contacts 12, 13 and 14, 15. When the torque departs from the normal, one or other set is bridged and one of two clutchactuating coils 33, 34 is energized. This connects one of the two bevel-wheels 24, 25 to the constantly-rotating shaft 26 and adjusts the resistance 17 in the shunt field. The double-throw switches 35, 36 control the relay connexions for motoring or braking. The setting of the torque at particular values is regulated by the controller 38, which adjusts the amount of the resistance 37 to be included in circuit with the coil 7. During motoring the windings 8, 9 act cumulatively, but during regeneration they oppose one another corresponding to the actions of the shunt and series fields. Specification 29752/13 is referred to.

Title: "free-wheel-clutch" type coupling
IPC: F16D45/00
Filed: 1927-03-26
Abstract: 268,379. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). March 27, 1926, [Convention date]. Clutches, freewheel, particularly for connecting an auxiliary motor to a prime mover at starting and for lowspeed running. A pinion 10 on the starting-motor shaft drives the member 1 at reduced speed, the clutch member 2 being keyed on the prime-mover shaft and carrying on pivots 5 bell-crank levers 3 pressed by springs 9. Arcuate shoes 7, faced with friction material 8, are pivoted at 6 to the levers 3, the other arms of which carry centrifugal masses 4. Due to the high coefficient of friction of the material 8, the angle may be large, and greater variation in this angle with wear is permissible; also the large effective area of the shoes reduces wear. As the prime-mover speeds up, the clutch shoes disengage on overrunning and are finally held out of contact by the centrifugal masses 4, stops (not shown) then maintaining them concentric with the member 1.

Abstract: 528,178. Hydrocarbons. ANGLO-IRANIAN OIL CO., Ltd., BIRCH, S. F., and BEYNON, J. H. March 16, 1939, No. 8443. [Class 2 (iii)] n-Butane and n-pentane are isomerized by heat treatment in the prescence of an aluminium halide to which a ferric halide, in a proportion of less than 20 per cent. by weight, has been added as promoter. The process may be operated in batches or continuously and in presence of hydrogen halide as further promoter. A temperature range of 50-200‹C. is employed and superatmospheric pressure, advantageously below 50 atmospheres, may be used whether the reaction is conducted in the liquid or vapour phase. The promoted catalyst may be used in admixture with inert carriers such as silica gel or active carbon. Experiments are described which show that an increased isomerization of n-butane results when a mixture of aluminium chloride with 1.7 per cent. anhydrous ferric chloride is used as catalyst, than when aluminium chloride alone or aluminium chloride in conjunction with hydrogen chloride are employed..

Title: Seismic exploration
IPC: G06G7/19
Filed: 1962-03-07
Abstract: 1,005,583. Seismic surveying. JERSEY PRODUCTION RESEARCH CO. March 7, 1962 [April 3, 1961], No. 8801/62. Heading H4D. In a seismic surveying system the seismic vibrator is controlled by a narrow electrical pulse which is first expanded into a relatively long duration signal by passage through a filteramplifier of broad frequency response and appreciable phase distortion such signal being reversed in time (e.g. by recording the expanded signal and then playing it back in reverse) before application to the vibrator or, alternatively, such signal being utilized directly and the reflected signals received by one or more geophones reversed in time, the reflected signals, whether reversed in time or not, being passed through the same filter-amplifier before application to a recording means. This arrangement results, for each reflected signal, in a convolution with itself reversed in time, i.e. in an autocorrelation, so that the reflected portions of the received signal are emphasized with respect to other portions. Fig. 6, shows one embodiment in which the narrow electrical pulse 12A (see also Fig. 1) is supplied via switch 17 to the filter amplifier 14, the expanded output of which (10, Fig. 1) is supplied via switch 18 to a recorder 20. The record so produced is then played-back reversed in time in play-back 22 to derive a signal for controlling the seismic vibrator 24 (e.g. of the hydraulic or electrodynamic type) and for application to a recorder 32. Fig. 2 shows at 24 the latter recorded trace together with the recorded traces 30A . . . 30n of the signals derived from detectors (i.e. geophones) 28A . . . 28n in response to seismic signals reflected by an interface such as 26. The record produced by 32 is then played-back in 34 and the derived signals supplied via the filteramplifier 14 (switches 17 and 18 now in position 2) to the seismogram recorder 36 on which traces 40, 42A . . . 42n (Fig. 2) corresponding to the traces 24, 30A . . . 30n are recorded. Suitable filter-amplifiers for producing the expanded signal from the narrow input pulse and utilizing (1) a rotating magnetic drum with spaced play-back heads or (2) a tapped delayline are described with reference to Figs. 4 and 9, respectively (not shown). Fig. 3 shows how the arrangement according to the invention discriminates between reflections from different interfaces such as 26, 27 (Fig. 6), such reflections giving rise respectively to the full line and the dotted line curves A which overlap to produce the composite signal B but which, in the recorded seismogram, are displaced in time as shown at 44, 46. A modification of the arrangement of Fig. 6 in which the output of the filteramplifier controls the vibrator directly (i.e. without reversal in time) and in which the geophone outputs are recorded and then playedback reversed in time before transmission through the filter-amplifier to the seismogram recorder is described with reference to Fig. 7 (not shown).
