Patent GB-232999-A (GB)
Title: An improved method or apparatus for measuring electricity
IPC: G01S1/02
Filed: 1923-11-05
Abstract: 232,999. Cooch, H. Nov. 5, 1923. Leader gear.-An electromotive force, particularly that induced by a leader cable in a search coil carried bv a ship or aircraft, is reduced in frequency and measured by observing the amplitude of the oscillation produced in an instrument tuned to the lower frequency. The invention is shown applied to a navigational apparatus as described in Specification 198,090, in which search coils 1, 2 are connected through frequencychangers 3 to moving-coil voltmeters 9, 10. The frequency-changers 3 may be of any type; as shown they consist of contacts 5, 6 vibrated by clockwork, tuning-fork, &c. at a frecuency equal to the sum or difference of the frequency to be measured and the natural frequency of the measuring and device. Condensers may be connected in parallel with the voltmeters or search coils or both and may form therewith two oscillatory circuits which are connected together intermittently by the frequency reducer. The measuring-instruments 9, 10 may be of the centre-zero moving-coil type, and may have a natural frequency of vibration of, for example, two periods per second; the frequency of the electromotive force induced in the ccils 1, 2 may be 33 periods per second, the frequency of vibration of the contacts 5, 6 being either 31 or 35 periods per second. A mirror 12 may be attached to the spindle of each voltmeter in place of a pointer and so arranged that a spot of light is thrown at the top of a tangential scale 15 in the zero position of the coil; a larger lineal movement is thus obtained per unit angular coil movement at the top end of the scale than at the bottom. The amplitude of oscillation is a measure of the field-strength and therefore of the vertical height of an aircraft above the leader cable. The scale may be graduated to indicate heights. The period of oscillation of the spots should be sufficiently low to permit a phase displacement of 180‹ to be appreciated, and therefore the relative direction of the currents in the coils 1, 2 to be determined.

Title: Preparation of dialkoxyvinylboranes
IPC: C07F5/02
Filed: 1961-07-31
Abstract: A dialkoxyvinylborane of the general formula H2C=CHB(OR)2, wherein R is an alkyl group, preferably containing 1 to 4 carbon atoms, is made by heating a solution of a metal trialkoxyvinylborate of the formula H2C=CHB(OR)3MgX, wherein X is a chlorine or bromine atom, in an anhydrous inert solvent having a boiling point higher than the decomposition temperature of the metal trialkoxyvinylborate until the latter is thermally decomposed and collecting the dialkoxyvinylborane which distils from the solution.  The solvent may be substituted or unsubstituted hydrocarbon or an ether.  Distillation of the dialkoxyvinylborane may be started as soon as the decomposition of the metal compound is reached, and by introducing fresh metal trialkoxyvinyl borate continuously to replace that which is decomposed, the process can be performed continously.  Reaction temperatures of 150 DEG C. to 275 DEG C. are preferred and the process may be effected at atmospheric or reduced pressures. Examples describe the preparation of diethoxy-, diisopropoxy-, and di-n-butoxy-vinylboranes.  Specification 856,856 is referred to.
