Title: Magnetic tape apparatus
IPC: G11B15/18
Filed: 1975-08-14
Abstract: 1474012 Automatic control of position INTERNATIONAL BUSINESS MACHINES CORP 14 Aug 1975 [7 Nov 1974] 33824/75 Heading G3R [Also in Division G5] In magnetic tape apparatus, a rotating head scans a pair of servo marks on the tape which are angularly inclined to each other. The system adjusts the post of the tape accordingly so as to correct alignment between the head and data tracks on the tape. In the embodiment shown, the servo marks 38, 111 correspond to read and erase gaps 101, 103 of the rotating head 13. As each gap passes a respective mark, a threshold circuit 124 produces an output 136 or 138. After a time delay on one output, if necessary, counter 142 counts clockpulses from 146 for the time difference between these outputs, which difference depends upon the head-servo mark i.e. data track alignment. The output of counter 142 is compared with a reference number, the result at 33 being used to adjust the tape position so as to correct any alignment error. The clock or reference number may be varied in accordance with tape or head speed. The servo tracks can be appplied, as Fig. 5, (not shown) to both ends of a data track, so as to allow for measurement and correction of skew between the head path and the data track. The system which may be digital or analogue, is used in apparatus as Fig. 1 (not shown), with tape tension control using a vacuum buffer, the tape being moved in steps, with the measurement or control of alignment before the read-write functions being made with the tape stationary or moving slowly past the rotating head.

Title: Improvements relating to polymers of olefines
IPC: C10M143/06
Filed: 1935-12-09
Abstract: <PICT:0455114/IV/1> Olefines containing less than 5 carbon atoms are polymerized in liquid phase in contact with sulphuric or fuming sulphuric acid, sulphur trioxide or halogen sulphonic acids at temperatures below -20 DEG  C., preferably together with a solvent capable of retaining the sulphuric catalyst in liquid condition. Suitable solvents are liquid sulphur dioxide, sulphur halides and oxyhalides and carbon disulphide.  The lower the temperature the higher is the molecular weight of the polymer, which may be 1000--5000 or more.  The products are viscous liquids or tacky plastics and are soluble in mineral oils to which they impart increased viscosity.  Strongly heated they depolymerize to gases without solid carbonaceous residues.  In examples: (1) and (2) isobutylene is polymerized at -36 DEG  C. and -80 DEG  C. with fuming sulphuric acid, propane being used as a diluent; the product may be distilled up to 400 DEG  F. to remove light ingredients, or the polymer may be precipitated with acetone and then steamed up to 400 DEG  F.  The polymers are added to SAE50 lubricating oil, figures being given to show the increases in viscosity.  In the apparatus shown, the liquefied olefine with or without diluent is supplied at 1 and forced through a heat-exchanger 3 and reaction tubes 6 enclosed in a casing 4 containing refrigerating-means, and sulphuric acid entering at 7 passes through a cooler 8 and is admitted to the reaction tubes 6 through pipes 7b, 7c, 7d.  The product passes by a pipe 9a to a mixing device 11, aqueous alkali being added at 10.  It is preferred to add alcohol or acetone to the alkali solution to avoid the production of emulsions.  The mixture is passed to a settling tank 12 from which the oily layer is taken to a tower 12a in which diluent and partially polymerized olefine is distilled off; an oily medium may be added in this tower to take up the polymer.  The Specification as open to inspection under Sect. 91 includes the treatment of low-boiling, preferably normally gaseous olefines.  This subject-matter does not appear in the Specification as accepted.ALSO:Polymers of olefines containing less than 5 carbon atoms obtained by treatment of the olefines with "sulphuric acid catalysts" below -20 DEG  C., which are viscous liquids to tacky solids, are used as a soluble addition to lubricating-oils to increase the viscosity.

Title: Multiplexer for telephone channels
IPC: H04J1/08
Filed: 1974-08-06
Abstract: 1468444 Frequency division multiplex COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 6 Aug 1974 [16 Aug 1973 12 June 1974] 34691/74 Heading H4M In a modulation system for forming a multiplex carrier group, a number of speech channels CE1 to CE12 are each subjected to premodulation by a common frequency F and filtered to remove one sideband at 4. Low frequency calling signals SE1 to SE12 are added direct to the filtered signals before they are modulated by respective carriers FM1 to FM12, differing each from the adjacent carriers by 4 kHz, the resulting signals are combined at 9 and fed both direct and via a filter 10 and modulator 11 to a combining circuit 13 and filter 14 to form a carrier group with the calling signals located in a predetermined position relative the respective carrier channels. As described the incoming speech channels are limited to the band 300 to 3400 Hz in filters 2, modulated at 3 with 128 kHz carriers, and the upper sideband passed to the second modulator 7 together with a respective calling signal SE1 to SE12 which has been band limited to a frequency below 200 Hz. The resulting signals, i.e. a 200 Hz calling signal and a 128 to 132 kHz communication signal are applied together to a respective second modulator fed with a frequency of between 192 and 236 kHz, to produce a carrier channel in the 60 to 180 kHz basic primary group, or a frequency of between 1232 and 1280 Hz to produce a carrier channel in the 1104 to 1152 kHz high frequency primary group, together with calling signals which are at the frequencies FM1 to FM12200 Hz. The second modulator outputs are combined at 9 and applied direct to the group filter 14 while the calling signals are selected by filter 10 and applied to a third modulator 11 fed with a carrier of 128 kHz + FA where FA is the position relative the voice signals in the channel in which it is desired that the calling signals should appear, usually either 0 or 3À825 kHz, so that the carrier would be 128 kHz or 131À825 kHz. The calling frequencies consequently are shifted to frequencies 64+n4 ... to 108 kHz or 60À175 ... + n4 ... to 104À175 kHz. At the receiver R, Fig. 1 the first demodulation by frequencies FM1 to FM12 allows the calling signals to be selected by filters 28 centred on the frequency 128+FA, while the speech channels are recovered by a second demodulation at 128 kHz in a standard way. In a similar system, Fig. 2 (not shown), the calling signals are fed in to the second modulator so that the calling signal for channel 1 is mixed with channel 12 speech signal and vice versa, &c., in which case the third modulator 10 is fed with a signal 300 - FA kHz for a 60 to 108 basic primary group or 2384-FA for a 1104-1152 high frequency primary group.
