Title: Preparation of titanium dioxide
IPC: C01G23/07
Filed: 1968-09-12
Abstract: 1,217,594. Vapour phase TiO 2  production. TITAN G.m.b.H. 12 Sept., 1968 [21 Sept., 1967], No. 43521/68. Heading C1N. In a process for producing TiO 2  by reacting TiCl 4  with O 2  using an auxiliary CO flame, a part of the CO and all the O 2  are introduced into a gas-permeable ceramic plate and combusted immediately downstream of it to give a hot O 2 - containing laminar flowing stream, TiCl 4  vapour is introduced axially into this stream in one or more jets which have turbulence, and each jet is surrounded by a shell of the other part of the CO. The plate may be perforated or may be a frit. The CO and O 2  may be fed to the plate separately or mixed. Preferably the amount of CO is such as to give a temperature in the plate of 1000-1700‹ C. Either part of the CO may be mixed with an inert gas, e.g. N 2 , Cl 2 , or reaction waste gas, e.g. part of the O 2  may be replaced by air. The TiCl 4  may contain minor amounts of AlCl 3 , SiCl 4 , ZrCl 4 , or H 2 O vapour. In Fig. 1, CO + O 2  is fed at 24 and through cylindrical bores 11 and perforations 10 in plate 2, which may be cylindrical or conical and inclined at not more than 20 degrees to the axis. TiCl 4  is fed at 26 and CO at 25 to feeds 12, each of which comprises tangential inlet (18) to inner pipe (13) having constriction (22) at its lower end and an enlarged mouth, for TiCl 4 , and inlet (16) to annulus (15) for the CO (Fig. 2, not shown). The wall of reaction chamber 1 may be scavenged by inert gas introduced tangentially at 27.

Title: Demodulator circuit arrangements for frequency-differential phase-modulated signals
IPC: H04L27/233
Filed: 1974-10-09
Abstract: 1489914 Frequency differential phase modulation multiplex transmission SIEMENS AG 9 Oct 1974 [19 Nov 1973] 43842/74 Heading H4M In a system for the concurrent transmission of data messages by frequency differential phase modulation, wherein each data message is transmitted by controlling the mutual phase difference of two carriers of adjacent frequency, the messages are demodulated at the receiver by a circuit arrangement in which the plurality of modulated carriers are applied (at A, Fig. 2) to a plurality of correlators (e.g., K1-K8). Reference carriers T1-T4 are applied via separate paths introducing a mutual phase difference to pairs of the correlators, e.g. K1, K2. In each case the D.C. output of the correlator represents the phase state of its received carriers. The outputs of pairs of correlators are applied to a time multiplex stage ZM operating such that the outputs of associated correlators are selectively connected to the two outputs B1, B2 of the multiplexer in sequential manner. The multiplexer output at any instant is connected to a phase modulator PM which provides a phase modulated signal whose zero transitions in successive modulation periods indicate the phase states of the carriers. This signal is applied to a phase sensitive analoguedigital converter AD which produces binary words from the analogue zero transitions signalling the phase states of the carriers and which are stored consecutively, adjacent words being subtracted to derive the transmitted data. Each reference signal T1-T4 is applied to two correlators, e.g. K1, K2, via a 90 degree phase shifter P1-P4 for one of the two. Each correlator output may change for each modulation period, related to the original data message, and is stored until sampled by the switches S1-S8, controlled by timed pulses H1-H4 from the generator GEN2. Gates S1, S2 are simultaneously opened so that the in phase and quadrature correlator outputs for a particular carrier T1 are passed to phase modulator circuits PH1, PH2 respectively, where they are combined with switching waveforms C11, C21  from GEN3 at twice the frequency of the switching signals H1-H4. The outputs from the modulators are added at SU. This provides a rectangular form output L which is band pass filtered at BP to provide an output M whose zero crossings represent the phase states of the successively selected carriers. These zero crossings are detected and digitized by the converter AD which provides a parallel binary output on lines E1-E5. This output is passed in alternate timing intervals to the stores SP1-SP2 respectively, in accordance with the switching waveforms H1-H4. The contents of the stores are successively subtracted at SB so that on the output lines G appear a succession of data words, each corresponding to the data transmitted as relative phase shift of an adjacent pair of carriers.

Filed: 1975-10-24
Abstract: 1520290 Automatic phase control THOMSON-CSF 24 Oct 1975 [25 Oct 1974] 43872/75. Heading H3A A phase acquisition loop comprising an amplifier 6 connected between the output from phase comparator 3 and the control input of variable frequency oscillator 1 and a sweep oscillator 7 coupled to a second input of the amplifier 6, the arrangement being such that the voltage from the sweep oscillator is applied to the control input of the oscillator 3 during periods of synchronization as well as during periods of out-of-synchronization condition. When the controlled oscillator 1 and the reference oscillator 4 are out of synchronization, the output signal from phase comparator 3 has a frequency too high to be passed by amplifier 6, so that the only signal received at the control input of oscillator 1 is that from the low frequency sweep oscillator 7. When the two oscillators are synchronized, the phase comparator output comprises an A.C. component lying within the amplifier pass band which is cancelled out by the sweep signal in amplifier 6 and a D.C. component which brings about phase lock.

Abstract: 1276347 Stuffer-box crimped acrylic fibres EI DU PONT DE NEMOURS & CO 5 Sept 1969 [20 Sept 1968] 44173/69 Headings D1F D1K and D1W Acrylic homocomponent fibres are characterised by having a random three-dimensional crimp, of 8 to 15 crimps per inch and having a length between ¢ and 1¢ inches. A process for producing fibres as above comprises the steps of 1) crimping homocomponent acrylic tow while at a temperature of 60‹-70‹C and wet in a stuffer-box; 2) immediately cooling the crimped tow to less than 60‹C; and 3) crimping the crimped tow while at a temperature of 80‹-95‹C and wet in a stuffer-box. By 'wet' is meant that the tow has a moisture content greater than 1% by weight. In a preferred embodiment the tow in step 1) has a water content of 60-90% by weight and is maintained at a temperature from 60‹ to 70‹C. In the third step of the process the tow preferably has a water content of 30-50% by weight. In a further embodiment of the process, the crimped tow after cooling in step 2) is dried while in a relaxed condition and in the final crimping step the tow has a water content of 2% by weight. The crimped tow is cut to staple length and formed into a sliver for use in making knit pile fabrics, the resultant fabric being sheared, fur ironed and if necessary sheared again.

Abstract: 1282391 Lasers A P PEDRICK 17 Sept 1970 44363/70 Heading H1C In a laser beam compression gun, as described in Specification 1,207,698 with reference to Figs. 7 to 15 thereof, mutually repelling magnets 12, 13 are mounted respectively in the projectile 5 and the barrel of the gun, as shown in the present Fig. 19. The immediate object is to improve the gun performance, i.e. to approach more closely the desideratum expressed in the prior patent, viz. that the projectile shall have, if possible, the speed of light. The ultimate object is the production of very high temperatures and hence to generate electricity. The greater part of the Specification is devoted to a theoretical consideration of the ultimate structure of matter, gravitational theory and the theory of magnetic repulsion. The impossibility of imparting to a body a speed greater than that of light is explained in terms of these theories.

Abstract: 1,158,630. Public address systems. NORTHERN ELECTRIC CO. Ltd. 5 Oct., 1966 [16 Oct., 1965], No. 44421/66. Heading H4J. In a sequential control arrangement intended primarily for use in a public address system for connecting a number of microphones to a loudspeaker circuit on a first-come first-served basis, a key is provided for each microphone and calls from persons using the microphones are registered to form a queue on columns of diodes which are connected between input control wires and sequence control wires. Thus the first caller takes the head of the queue and his microphone is connected up, and when he replaces his key all the subsequent calls move up one place in the queue. If a caller withdraws from the queue, later calls all advance. The arrangement may be adapted for effecting a series of control operations in succession.

Filed: 1961-12-15
Abstract: 932,198. Electric writing-telegraph systems. VICTOR COMPTOMETER CORPORATION. Dec. 15, 1961 [Dec. 27, 1960], No. 44987/61. Class 40 (1). A writing-telegraph system with a plurality of transmitters and receivers interconnected via a central station, incorporates a dialling system and circuit condition indicating means to determine whether a selected receiving station is available or busy. As shown (Fig. 2), an operator wishing to transmit, calls the central station by closing switch 19. If lines are available, the central station sends back a dialling tone at a continuous low frequency, e.g. 600 cycles per second, which passes through L.F. filter 36, and is amplified by transistors 34, 47 to energize relay 53, causing continuous operation of lamp 21A and buzzer 21B. Relay 53 also short-circuits the local transmitter 16 and receiver 17 to prevent extraneous operation by the dial signal. The operator now dials the preselected receiver in conventional manner on dial switches 23, 24. If the selected receiver is busy, an intermittent L.F. signal is received, producing intermittent response on lamp 21A and buzzer 21B. The writing telegraph system per se transmits to the receiver the co-ordinate values of the position of a stylus in the form of frequency modulated signals, using a higher frequency band than that used for circuitcondition signalling. Hence the indicators 21A, 21B are not actuated by the data signals.
