Title: Converting time division multiplex signals to frequency division multiplex signals
IPC: H04J4/00
Filed: 1976-04-15
Abstract: 1520805 Converting TDM to FDM signals PLESSEY CO Ltd 15 April 1976 [25 April 1975] 17342/75 Heading H4M In an arrangement for converting a stream of PCM, TDM signals to multichannel FDM signals, which avoids the complexity of arrangements which incorporate sine and cosine modulators and transversal filters for each channel, use is made of a single inverse fast Fourier transform device (IFFT) whose output are applied to a stage incorporating a periodically varying digital filter. The stream of multichannel PCM signals (made up by two 30 channel TDM systems) is applied to a first stage having two branches, each with an inverter and multiplexer such that each multiplexer responds to both incoming and inverted bit signals and appropriate clock signals 110011 and 001100, such that cosine and sine output waveforms are produced respectively from the branches. These waveforms are applied respectively to cosine and sine channel demultiplexers each having a separate output path for each channel, the two demultiplexers providing output waveforms which are relatively phase shifted by 90 degrees. These waveforms are applied to the IFFT which produces odd harmonic signals at one output and even harmonic outputs at a second output. These signals are applied to periodically varying digital filters PVDF1 and PVDF2 responsive to odd and even harmonics respectively. Both filters have variable multiplier values controlled from the variable outputs of a memory device ROM. The output from the first filter is applied directly to a summing device Al whereas the output from the second, in direct and inverted form, is connected to a clock controlled multiplexer, in turn having its output connected to the summing device Al. The summing device provides an output representing the channels in multichannel FDM form, which can be frequency converted to an appropriate super group range. The theory underlying this procedure is extensively discussed in the Specification.

Title: Improvements in and relating to the de-alkylation of aromatic hydrocarbons
Inventor: CLOUGH HARRY
IPC: C07C4/18
Filed: 1950-07-17
Abstract: De-alkylation of monocyclic aromatic hydrocarbons is effected by treating a feed consisting substantially of one or more alkyl-substituted monocyclic aromatic hydrocarbons at 500-600 DEG , preferably 540-570 DEG  C. and above 100, preferably 200-300, atmospheres with hydrogen in the presence of a catalyst consisting of silica, a mixture of silica and alumina, alumina pretreated with silicon tetrafluoride or an aluminium silicate which has not undergone a swelling treatment with a liquid swelling agent.  While alkyl groups such as ethyl and propyl may be removed, the process is particularly suitable for methyl groups, e.g. in toluene, xylenes, and trimethylbenzenes.  Products obtained from petroleum products and from coal or coal tar may also be treated.  The catalysts may include hydrogenating metals or their compounds, e.g. platinum and oxides of molybdenum, tungsten, and manganese, when the sulphur content of the hydrocarbon is at the same time reduced, and silicon tetrafluoride. In the latter case, periodic additions are desirable.  Batch or continuous operation is used.  Catalyst may be regenerated by treating with oxygen-containing gas and/or steam.  Examples describe the conversion of xylenes to benzene and toluene at 550 DEG  C. and 250-260 atmospheres, the catalysts being: silica-alumina made by impregnating silica gel granules with aluminium nitrate and calcining at 400 DEG  C. or precipitating aluminium nitrate and sodium silicate from solution with ammonia, extruding, and calcining; "Superfiltrol," an aluminium silicate earth; g -alumina dried at 450 DEG  C. and saturated with silicon tetrafluoride and, optionally, impregnated with ammonium orthomolybdate to give 1 per cent MoO3 in the calcined product.  Specifications 637,595 and 712,981 are referred to.

The fans draw in air through inlets 90 from chambers 81, and, under control of a damper 115, operated by an external lever 117, discharge it into an outlet chamber 82, on the walls of which are situated the outlet louvres. The chambers are separated by a partition 80. The louvres 44 are arranged in two adjacent groups, and are pivotally mounted at each end, each group being connected by a link 51 which is pivotally connected to flanges 50 on the louvres, both groups being simultaneously operated by a lever 54 to direct the outgoing air either upwardly or downwardly, or to close the opening. The plate 64, when opened, directs the air upwardly and rearwardly. The speed of the fans is controlled by a rheostat 110 regulated by a knob 113. The device is divided into three separable units, Fig. 9, to facilitate manufacture or repair, and these comprise the back and bottom walls 23, 24, a member 93, Fig. 4, on which is mounted the blowers and partition 80, and a cover constituted by the front, top and end walls 25, 26, 27, 28, and secured by screws 78 to the bottom wall.

Title: Improvements in or relating to electrical condensers of the variable differential type
Filed: 1928-06-22
Abstract: 311,131. Sullivan, Ltd., H. W., and Griffiths, W. H. F. June 22, 1928. Condensers. - Relates to condensers of the variable differential type comprising two condenser systems and means for simultaneously varying their capacities in opposite senses, such a condenser often consisting of a single movable system common to two independent fixed systems, and being applied to the determination of the " out - of - balance " capacity of telephone cable conductors. The conductor systems in this latter case are usually screened by an earth-connected metal case, and the differential condenser is combined with a range-extending condenser or condensers which can be connected at will across either of the two systems of variable capacity, and with a balancing condenser or condensers which is connected between an earth connection, for instance the screen, and the independent conductor system of the other system of variable capacity. In this way the range of " out-of-balance " capacity of the differential condenser can be varied without destroying the symmetry of the electric potential of the independent conductor systems with respect to the potential of the screen or earth. A differential condenser comprises two fixed systems 11, 12 and a moving system 13 all enclosed by an earthed screen 14. The rangeextending capacity 15 is fixed and comprises two sets 16, 17 of conductors and a screen 18. The balancing capacity 20 has a fixed conductor 21 and a screen 22 which is connected to the other two screens 14, 18. The capacities 15, 20 are connected in circuit by means of two switches 25, 26, which, in the position shown, connect the capacity 15 across the system 11, 13 by way of contacts 28, 29 and bar 27 and the capacity 20 between the system 12 and the screen 14 by way of contacts 32, 33 and the bar 31. The value of the capacity 20 is chosen the same as the capacity between the system 16 and screen 18 in order, as above stated, not to destroy the symmetry of potential. By changing over the switches 25, 26, the capacity 15 can be connected across the system 12, 13 and the capacity 20 between the system 11 and screen 14. Plugs may be used instead of switches. An arrangement is described (Fig. 2, not shown) whereby the plate 17 is completely disconnected when the capacity 15 is cut out of circuit, and another arrangement (Fig. 3, not shown) is described showing how two rangeextending capacities may be added.

Title: Improvements in or relating to fabric take-ups for circular, independent needle, knitting machines
IPC: D04B15/88

Abstract: 748,296. Feeding webs. HEMPHILL CO. June 30, 1953 [Aug. 28, 1952], No. 18130/53. Class 100 (1). [Also in Group VIII] A loop of fabric extending between the machine and take-up rollers 5, 6 supports a weighted roller 1 which maintains the tension of the fabric substantially constant, any variation in the loop length due to a variation in the production rate causing the roller to fall or rise and thereby immobilizing or mobilizing the ratchet mechanism 8, 9 driving the take-up rollers 5, 6. The ratchet mechanism 8, 9 drives the take-up rollers at a rate such that the fabric will be taken up at a rate in excess of that at which it is produced. As the roller 1 is raised a pin 27 engages lever 24 to cause a catch 25 to hold the rocking arm 14, operating the ratchet mechanism through rod 11, stationary, thereby stopping the operation of the take-up rollers. As the loop length increases and the roller 1 drops, a pin 21 engages the lever 24 and causes it to release the catch 25 and permit operation of the ratchet mechanism.
