Abstract: 406,545. Speedometers. FABER, J. A. C., c/o Koninklijke Paketvaart Maatschappij, Koningsplein-Oost, Batavia, Java, Dutch East Indies. June 19, 1933, No. 17464. Convention date, April 4. [Class 106 (iii).] In apparatus for recording the varying movements of a shaft, the shaft is provided with a screw thread on which is rotatably mounted an internallythreaded flywheel, means being arranged to exert an axial pressure on the flywheel to urge it towards its mid-position on the shaft, the deviation of the flywheel from said midposition being recorded on a moving record strip. The shaft 1 connected, e.g., to the propeller shaft of a ship, is screwed and carries the flywheel 2 having an extended boss 3 terminating in ball bearings 4 supported by plates 5, 10 slidably mounted on rods 6, 7 and held in position by adjustable springs 8. The members 5, 6, 7, 10 form a cage surrounding the flywheel, the cage being prevented from rotating by a projection 16 secured to the rod 17 and moving in a slot in a guide 19. The projection 16 carries a recording point 18 marking on a strip 20. The flywheel and cage are urged towards the centre of the shaft 1 by springs 11, 12. The record strip may be actuated by clockwork mechanism 22 started by each operation of the engine telegraph, as described in Specification 406,180. When the speed of the shaft 1 changes, the inertia of the flywheel causes it to move along the shaft. With the accelerations usual in practice, the axial position of the flywheel is stated to be approximately proportional to the speed of the shaft.

Title: Improvements in or relating to frequency modulators
IPC: H04B7/155
Filed: 1963-05-03
Abstract: 1,018,704. Frequency modulation. SIEMENS & HALSKE A.G. May 3, 1963 [May 4, 1962], No. 17487/63. Heading H3R. Varactor diodes are included in the tuned collector circuits of a pair of transistor oscillators of different mean frequency, and their capacitances oppositely modulated by a signal, so that even order non-linearity of the frequency modulations cancel out from their difference frequency taken in a mixer stage. The varactor diodes may be pairs in series opposition, and each pair oppositely connected if the modulation input to the centre of each pair is single-ended. In this case, the varactor biases are different to give equal frequency swing from each pair. Moreover since changes of mean frequency due to the respective modulations may be unequal, this can be compensated L by selective choice of the - ratios for each- C oscillator. Alternatively the varactor pairs may be similarly coupled in series opposition and the modulation applied in push-pull. The oscillators may be connected through a directional coupler to the mixer, one at least input to the coupler having a filter to suppress oscillator harmonics. The coupling of each oscillator to the mixer may also be frequency dependent to compensate for third harmonic distortion. The collector circuit inductances of the oscillators may be the primary coils of output transformers, and the primary inductance may be varied by an A.F.C. motor controlled by a frequency discriminator connected to the mixer output. The oscillators may be used in a microwave beam or waveguide relaying system, .and a pilot frequency outside the normal modulation frequency band used for A.F.C. motor control of one oscillator.

Filed: 1948-07-01
Abstract: 674,627. Cathode-ray oscillographs. JACKSON, E. H. T. July 1, 1949 [July 1, 1948; Aug. 23, 1948], Nos. 17716/48 and 22191/48. Class 37. A voltage to be measured is applied, together with an alternating voltage of predetermined frequency, to a pulse generator by which pulses are produced of a duration proportional to the voltage to be measured. The output of the pulse generator is amplified and differentiated giving sharp pulses which trigger a blocking oscillator, the output of which is applied to a series of cathode-ray oscillographs. An alternating voltage from a source d is applied to a grid of a heptode V1, to two other connected grids 10, 11. The output of the valve to be measured from terminals 10, 11. The output of the valve V1 consists of rectangular pulses and is amplified by pentodes V2, V3. The voltage across the cathode load of the valve V3 is differentiated by a valve V4, producing sharp pulses the interval between which is proportional to the voltage to be measured. These pulses trigger a blocking oscillator V5, the output of which is applied to the deflecting elements of cathode-ray oscillographs k, l, m. The valves VI ... V5 are supplied from a D.C. source e. The time base generator of the oscillograph k is of the same frequency as the source d and synchronized with it by a signal from the anode of the valve V3. The index on the screen takes up a steady position the distance of which from zero is proportional to the time interval between the pulses, and thus to the voltage to be measured. The time base of the oscillograph l is synchronized from the oscillograph k and the oscillograph m from the oscillograph l in sequence, with increasing frequencies, so as to produce a decade system in which the oscillograph l has ten times the sensitivity of the oscillograph k and so on.

Title: Improvements in or relating to the preparation of metal alcoholates
Inventor: HASLAM JOHN HARRIS
IPC: C07C29/70
Filed: 1954-06-17
Abstract: <PICT:0787180/IV (b)/1> Metal alcoholates are obtained by reacting a tertiary alcohol, allylic alcohol, or b -keto alcohol with the ammonia addition product of a halide of a metal having a valency of at least 3 and an atomic number greater than 12 and less than 57, said addition product containing at least one nitrogen atom for each atom of halogen in said halide.  Specified metals are titanium, zirconium, iron, arsenic, antimony, tin, and aluminium and specified alcohols include tert.-butyl and tert-amyl alcohols, 1-methyl cyclopentanol, triphenyl carbinol, allyl alcohol, acetyl carbinol, 1-aceto propyl alcohol, and 1-acetobutyl alcohol.  It is preferred to use the chlorides of titanium, zirconium, iron, antimony or tin but other halides, e.g. the bromides and iodides of these metals can also be used.  The reaction is preferably carried out at a temperature of at least 40 DEG  C., e.. aat from 40 DEG  C. up to the boiling-point of the alcohol used.  The ammonia addition product may be formed by passing anhydrous ammonia into a solution of the halide reactant, e.g. titanium tetrachloride, in an inert organic solvent and then mixed with the alcohol and the mixture heated to form the metal alcoholate.  In the Figure, the metal chloride, e.g. titanium tetrachloride, is dissolved in a suitable solvent, e.g. cyclohexane, n-heptane, benzene, toluene, or xylene, in the storage vessel 1 and the solution passed to a mixing zone 7 where it mixes with a solution formed by passing anhydrous ammonia from conduit 9 into a solvent of the same type from storage vessel 2.  The ammonia solution becomes homogeneous in the mixing conduit 8 and is injected into the stream of metal halide solution which is being discharged into the zone 7 where the mixing is very rapid.  The alcohol reactant which may be heated, if desired, is fed from vessel 3 through line 6 into the discharge line 10 which discharges the reaction mixture into a heated baffled digestion chamber 11 provided with heating coils 12, an outlet 13 and a refluxing tower 14.  The ammonium chloride crystals formed in the reaction grow to a filterable size in the digestion chamber and escape of excess ammonia and refluxing of solvent is effected by means of the column 14 and outlet 15. Examples are given for the production from the corresponding alcohol and metal chloride-ammonia addition product of (1) tertiary butyl titanate; (2) tertiary amyl titanate; (3) tertiary butyl antimonite; and (4) the ferric alcoholate derived from tertiary butyl alcohol.  The ammonia-metal chloride addition products formed in these examples are stated to have the approximate compositions TiCl48NH3, SbCl3.3NH3 and FeCl35NH3 (or FeCl36NH3).  Specification 479,470 is referred to.
