Title: Aluminium titanium chloride composition
IPC: C08F110/06
Filed: 1957-12-19
Abstract: A compound having the empirical formula AlTi2Cl8 (see Group III) when dispersed in a non-polar inert liquid together with a strongly anionic agent, such as lithium or sodium aluminium hydrides, will catalyse the polymerization of propylene to solid polymers, or, dispersed in a non-polar inert liquid together with a strongly cationic agent, such as titanium tetrachloride, or a Friedel-Crafts type catalyst, will catalyse the polymerization of ethylene to solid polymers.  In an example, a reaction bomb was flushed with nitrogen, mixed hexanes, AlTi2Cl8 and lithium aluminium hydride introduced, propylene was added and the bomb sealed at atmospheric pressure. The bomb was heated to 71 DEG C.-87 DEG C. with shaking the pressure rising to 130-180 p.s.i.g.  More propylene was added, and heating was continued to 92 DEG C.-97 DEG C., the pressure being 130-215 p.s.i.g. The bomb was then cooled, opened, flushed with nitrogen, and the contents immersed in isopropyl alcohol.  The volume of this mix was then reduced by evaporation, and water and 12N hydrochloric acid added, followed by further heating.  The mass was filtered and the cake washed with water, ground, suspended in a mixture of water, 12N hydrochloric acid and 2-propanol, heated and filtered.  The cake was washed with water and ammonia, and extracted with diethyl ether to remove amorphous polymer.  The ether washings were treated with methanol and water to precipitate the amorphous polymer as a gummy mass The polymer remaining after ether extraction was a crystalline polymer, with a melting point in the range of 160 DEG C. to 163 DEG C.  Specification 856,645 is referred to.ALSO:A compound having the empirical formula AlTi2Cl8 is prepared by reacting aluminium and titanium tetrachloride at 80 DEG C. to 200 DEG C. in a hydrocarbon medium.  The compound contains no detectable free AlCl3, TiCl2, TiCl3, TiCl4 or Al.  Any liquid hydrocarbon may be employed.  In an example, a reactor is flushed with nitrogen, and aluminium powder, hexane, and the stoichiometric quantity of titanium tetrachloride are introduced, after which the reactor is again flushed.  The reactor is sealed at atmospheric pressure and maintained at 120 DEG C. for 16 hours, after which it is cooled, flushed with nitrogen, and the contents filtered in a nitrogen atmosphere.  The filter cake is washed with hexane and dried.  A solid reddish-purple amorphous material is obtained.  AlTi2Cl8 catalyses the polymerization of ethylene or propylene, when mixed with a strongly anionic agent, such as lithium or sodium aluminium hydrides and dispersed in an inert non-polar liquid, or dispersed with a strongly cationic agent such as titanium tetrachloride or a Friedel-Crafts type catalyst. Specification 856,645 is referred to.

Title: Frequency-division multiplex carrier frequency communication  systems
IPC: H04J1/06
Filed: 1972-08-25
Abstract: 1396135 Multiplex systems SIEMENS AG 25 Aug 1972 [27 Aug 1971] 39612/72 Heading H4R In a frequency division multiplex carrier frequency transmission system each carrier or pilot frequency is generated by a respective phase locked loop oscillator controlled by a common control frequency. As described, the carriers TG1-TG3 of the tertiary group, and QG1, QG2 of the quaternary group and the quaternary group pilot QGPil, are generated by the phase locked loop generator Tr. Each generator comprises, as shown in Fig. 2, an oscillator Os 2  whose frequency is controlled by a reactance diode Var fed with a D.C. control voltage derived by comparison of the common control frequeney f st  and a divided output of the oscillator in a phase comparator D. The control voltage U is also applied to two threshold detectors G1 and G2, direct to one G1, and via a differentiation circuit to the other G2. The first threshold detector G1 detects excursions of the control voltage corresponding to a frequency deviation of the oscillator Os 2  outside the pull-in range, while the second threshold detector detects rapid changes in the control voltage resulting from a gross error in the oscillator Os 2  frequency which causes cyclic phase changes which would switch detector G1 continuously on and off. The two detector outputs are connected to control gates on the oscillator output to inhibit the output and raise an alarm if the signal is of incorrect frequency. Circuits of the threshold detectors, Fig. 5 (not shown), and the oscillator control circuit, Fig. 6 (not shown), are described.

Title: Keying devices, particularly for electrical musical instruments
IPC: G10H1/055
Filed: 1961-11-06
Abstract: 974,760. Electrophonic organs. A. H. MICHEL. Nov. 6, 1961 [Nov. 9, 1960], No. 39621/61, Heading G5J. [Also in Divisions H1 and H3] A non-contact making switch in an electrophonic organ comprises a transformer with a magnetic core providing a variable magnetic coupling between primary and secondary windings and core being saturated or de-saturated by means of a movable permanent magnet. The impedance of the secondary winding at least is varied along with the magnetic coupling. In Fig. 4 a permanent magnet normally saturates a ferrite core D. The coupling between windings A, B is restored as the magnet is shifted. The core D may have a stepped cross-sectional area so that only the part of the core D within winding B is saturated. The core may have a toroidal form, Fig. 6. The toroidal core may have a varying cross-sectional area, Fig. 7. In a known switch having no permanent magnet, a core D, Fig. 3 is shifted between primary and secondary windings A, B to control the coupling. A core F of electrical conducting material ensures that the reactance of winding B is low when the coupling is low. Coil C compensates for any disturbance induced by winding A in winding B when contact E is closed.

Filed: 1974-09-18
Abstract: 1448605 Lasers INTERNATIONAL BUSINESS MACHINES CORP 18 Sept 1974 [28 Dec 1973] 40596/74 Heading H1C Double quanta emission is produced by a volatile monoiodide compound such as CF 3 I, CH 3 I and C 2 F 7 I. As shown the monoiodide is contained in a laser cell 28 pumped by a xenon lamp 30, the excited vapour stimulating two input frequencies V S  and V R  to produce double quanta transitions V S  + V R . The input frequencies are derived from a system comprising a pulsed ruby or neodymium glass laser 2 emitting light at a frequency V L , a stimulated emission iodine vapour raman cell 6, a four wave parametric iodine vapour conversion cell 18, and a silicon or gaseous iodine filter 26 rejecting the initial laser frequency V L . Both cells 6 and 18 are pumped by common or individual zenon lamps 12, 20, the pumping frequencies below 5000  being rejected by filters 10, 22. In operation the initial laser frequency V L  produces a stimulated raman stokes frequency V S  in its passage through cell 6. These two frequencies in cell 18 react to produce a radiative transition of V L  = 2V S  + V R , only the latter frequencies being passed as inputs to the laser cell 28 by the filter 26. Cells 6 and 18 are both heated to respective temperatures of 1200 and 100 C., and have corresponding iodine vapour pressures of one half of an atmosphere and 10 Torr.

Patent GB-901905-A (GB)
Title: Parametric amplifier
IPC: H03F7/04
Filed: 1960-11-30
Abstract: 901,905. Parametric amplifiers. HUGHES AIRCRAFT CO. Nov. 30, 1960 [Dec. 18, 1959], No. 41221/60. Class 40 (9). A parametric amplifier comprises a coaxial line 22 for carrying the signal energy, which carries a stub tuner 21 for tuning it to resonance at the signal frequency and contains a band-pass filter 41 permitting only signal frequencies to pass; the centre conductor being connected through an aperture of a wall of a rectangular waveguide via a non-linear reactance device 28 to the opposite wall 46; and the rectangular wave-guide, which is fed from the left-hand end with pump frequency, containing a high-pass filter 47. The portion 14 of the wave-guide is tuned to the idler frequency by the plunger 18. With the pump frequency being higher than the signal, frequency, the wave-guide 11 may be constructed to be beyond cut-off with respect to the signal frequency. Hence any adjustments to the wave-guide either in the idler section or on the pump supply side do not affect the signal tuning. The filter 41 prevents the adjustment of the stub tuner 21 from affecting the tuning of the idler and pump circuits. The high-pass filter, which may be a section of reduced width formed by the insertion of a conductive block 47 in the wave-guide 11, prevents any tuning of the pump source from affecting the tuning of the idler circuit. Termination of the coaxial cable at the wave-guide is effected by the non-linear reactance which is a semi-conductor diode acting as a variable capacitance in conjunction with an inductive iris 36. The pump frequency may be conveyed from a standard wave-guide 11 to the operative part of the wave-guide which is of reduced height via a matching portion having a linearly changing height. This concentrates the pump field at the diode and also achieves a measure of broadening of the signal band-width. In an alternative construction the semiconductor diode is mounted in a sleeve of insulating material passing through a hole in the lower wall of the wave-guide. This enables back-bias to be applied to the diode. The broadening of the signal band-width may be further enhanced by providing a broader idler band-width. This may be effected by broadening the end of the idler cavity nearest the plunger 18, making both the broader and narrower portions of this cavity of 90 degrees length at the idler frequency.
