Title: Improvements in and relating to methods and apparatus for the detection and measurement of frequency variations of electro-magnetic oscillations and the like purposes
IPC: H03D3/24
Filed: 1932-09-15
Abstract: 410,482. Indicating vibrations. REGNAULD DE BELLESCIZE, H. J. J. M. DE, 47, Boulevard de la Seine, Neuilly-sur-Seine, France. Sept. 15, 1932, No. 25681. Convention date, Jan. 8. [Class 106 (iv).] A method for investigating a physical phenomena such as a seismic tremor, and in which the phenomenon under investigation is not affected by the detecting apparatus, consists in separately generating two oscillations, causing the phenomena to act on means controlling the frequency of one of the oscillations, bringing the oscillations into "locked synchronism" and measuring the limited phase difference produced by the frequency control. The term "locked synchronism" is defined in Specification 392,567, [Group XL], to which reference is made, and additionally the term includes the feature of a permanent change of phase produced by a change in the frequency of the oscillation generators. The phase difference of the two oscillators is maintained between two limiting values both close to 90‹ and distant from zero or 180‹. In one arrangement, Fig. 1, the oscillation varied by the phenomenon under investigation is received on the aerial 1 and an auxiliary oscillator 4 is provided for modifying the frequency to a value appropriate to the attainment of a condition of " locked synchronism." The oscillations from a valve oscillator 6 and those modified by the phenomena under investigation react in an asymmetrical conducting device such as the valve 7, the resulting low frequency current in the resistance 9 effecting control of synchronous conditions. This controlling current becomes non-sinusoidal at synchronism and is amplified at 16 and fed to an oscillograph 18. Capacitance variations produced by air vibrations due to seismic tremors acting on an electrostatic microphone influence the synchronizing current in a " locked synchronous " system, the corresponding potential variations being applied to a receiving instrument or transmitted to a distance. An electrodynamic microphone may be employed, the air vibrations varying an inductance unit in one of the oscillatory circuits.

Abstract: 680,199. Switch cases. IGRANIC ELECTRIC CO., Ltd. July 7,1950 [July 9,1949], No. 26196/51, Divided out of 680,165. Class 38 (v) [Also in Group XXV] A cabinet 10 houses electrical equipment controlled by an isolating switch 85 connected by a tongue and groove coupling 84 to a shaft 78 which is journalled in a door 11 and is provided with an external operating handle 80. Rotation of the shaft serves to move the switch to the 'off' position and also to unlock the door by withdrawing a slidable bolt 82. Opening of the door breaks the coupling and results in the rotation by spring means of a shaft 35 and the consequent disengagement of a latch 38 carried by the latter from a keeper 39 mounted on an adjacent door 12. A rod 44 coupled to the shaft 35 is also projected outwardly. Subsequent closing of door 11 pushes the rod inwardly to rotate the shaft 35 and effect the latching of door 12, while the shaft 78 becomes recoupled with the isolating switch. A device is also provided for preventing the rotation of shaft 35 if door 12 is open, the projecting rod 44 than acting as a stop for preventing the closing of door 11. The device comprises an angle member 67a pivotally mounted on the door 12 and biassed by a spring 71 into the path of latch 38 when door 12 is opened. The door interlocking mechanism and switch operating means per se are described and claimed in Specification 680,165.

IPC: H04L23/02
Filed: 1964-06-25
Abstract: 1,064,194. Electric selective signalling. FERRANTI Ltd. June 25, 1964 [June 27, 1963], No. 26237/64. Heading G4H. A transmission system imparts an orthogonal transformation to n discretely valued input elements to produce n transformed elements for transmission which are such that n-m of the transformed elements uniquely define the corresponding n input elements. In one embodiment, input elements have the values + 1, 0, or - 1. The orthogonal transformation takes place at 29 which is fed by pairs of input elements. Either one of the resultant elements enables the two input elements to be derived. The received elements are transformed back to the input elements by unit 55. If either of the transmitted elements is not received, its absence is detected at 31 or 33 so that any output from unit 55 is inhibited, as is the output from corresponding encoder unit 38 or 44, by the gating arrangement shown. However, the other encoder unit 44 or 38 will provide two elements which are identical to the input elements. Where erasure is likely to last for the period of several elements the elements of a pair are spaced apart by a time greater than that of the expected erasure and are interleaved with elements of other pairs, the elements being transmitted serially on one channel.
