Title: A data transmission system
Inventor: KLOSE ULRICH
IPC: H04L12/423
Filed: 1969-12-04
Abstract: 1,256,024. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 4 Dec., 1969 [20 Dec., 1968], No. 59160/69. Heading H4P. [Also in Divisions G4-G6] A data transmission system comprises a plurality of stations 1-17 arranged in a closed loop, each station I-M including a by-pass (not shown in Fig. 1) that can be broken when the corresponding station receives or transmits signals; when signals are interchanged by two stations, the signal from one station passes around one portion of the closed loop, while the signal from the second station passes around the remaining portion of the loop. As described in relation to airline seat reservation, the system includes a central station 1 and area stations 2- 17 interconnected through modulators 18, 20, 22, 24 and demodulators 19, 21, 23, 25. All signals, which are in binary-coded-decimal form, are transmitted counterclockwise around the loop; an area station (illustrated in Fig. 2, not reproduced) receives and transmits signals in serial form, but converts them internally to parallel mode. If the central station 1 wishes to receive data, it transmits around the loop a SEND ADDRESS signal, all area stations desiring communication replying by transmitting their address. The centr al station 1 then interrogates these stations in turn by sending a control signal to instigate transmission of each data character. If the central station 1 wishes to send data to area station 4, this address is transmitted around the loop and decoded in area station 4, which then breaks its by-pass. Data transmission then occurs, instigated by control signals sent from area station 4 to the central station 1. The central station 1 instigates data transmission between pairs of area stations by sending a CALL signal around the loop, which is replied to by a TAKE signal from area stations desiring communication. A pair of area stations then interchange control and data signals. Each area station 2-17 (see also Fig. 2, which shows an area station) controls its by-pass with an AND gate (36); the area station is controlled by internal logic (39).

Abstract: 636,121. Electromagnetic ammeters and voltmeters. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 21, 1946, No. 34548. Convention date, May 28, 1943. [Class 37] A moving coil measuring instrument wherein a single coreless moving coil operates with a non- uniform magnetic field to produce a logarithmic characteristic is so designed that the magnetic torque varies with deflection inversely as the ratio which the magnetic torque that would be exerted by a uniform magnetic field bears to a restoring torque proportional to the deflection. The invention is utilized in contructing a photo-electric exposure meter. In Fig. 2 the width 3 of the poles NZ is small compared with the length of the air gap, i.e. the dimension of the air gap in the plane of the paper and perpendicular to the width 3. In Fig. 1, the straight line 2 represents the relation between deflection and restoring torque of a torsional suspension so dimensioned that at 8 microamps. the deflection is 30 degrees. The curve 1 shows the relation between deflection and magnetic torque, which would obtain with the coil in a constant field of 2000 Gauss throughout the range of movement. With Fig. 1 related to Fig. 2 the coil moves in a substantially uniform field to 25 degreesunity ratio between ordinates-and then follows a non-uniform field path wherein at 30 degrees, 45 degrees and 60 degrees deflection the field strength values are proportional, respectively, to ordinate ratio values a/b, c/d and elf. Specification 626,134 is referred to.

IPC: C07C51/56
Abstract: 783,025. Phthalic anhydride. CHEMPATENTS, Inc. Sept. 12, 1955 [Oct. 25, 1954], No. 25959/55. Class 2 (3). Phthalic anhydride is prepared by heating phthalic acid in the presence of a saturated aliphatic mono-carboxylic acid having 2 to 8 carbon atoms in the molecule, in the proportions of 0.1 to 2.0 mols. of aliphatic acid per mol. of phthalic acid. The process may be effected at temperatures of from 120‹ to 300‹ C. and at pressures of from 50 to 800 mm/Hg. Aliphatic acids specified are acetic, propionic, normal, iso-, or secondary butyric, pentanoic, iso-valeric, caproic, heptanoic and octanoic acids and mixtures thereof. The phthalic acid may be a mixture containing 10-100 per cent of phthalic acid, and may be prepared from lower di-alkyl benzenes containing the o-isomer by oxidation with nitric acid or by catalytic liquid phase air oxidation. The dehydration may be conducted by heating the mixture of crude phthalic acid and the aliphatic acid to reflux, water vapour being removed by distillation until dehydration is complete, the aliphatic acid then being distilled off, the molten phthalic anhydride filtered to remove solid impurities such as terephthalic and isophthalic acids, and purified by distillation. Alternatively, the crude reaction product may be cooled and phthalic anhydride recovered by extraction of the solid mixture with solvents such as acetone, methyl ethyl ketone or benzene. Examples illustrate the dehydration of phthalic acid, prepared by oxidation of o-xylene-containing p- and m-isomers with air in the presence of acetic acid and manganese bromide, using (1) acetic acid and (2) iso-valeric acid.

Abstract: The invention relates to expansive cement compositions and to expansion agents containing free lime for use in such composition. Novel expansion agents are prepared by heating lime of particle size less than 250 microns and comprising at least 36 wt % of CaO in an atmosphere comprising water vapor at 100 to 400 DEG C or carbon dioxide at 350 to 850 DEG C when the particles contain less than 8 wt % Ca(OH)2, or by heating a partially hydrated lime at a temperature of at least 100 DEG C when the particles contain from 8 to 64 wt % Ca(OH)2. The encapsulated limes produced in this way are useful as expansion agents in hydratable cement compositions, the amount thereof generally being less than 30%, preferably 3 to 10%, based on the weight of the cement and the additive. Cement compositions containing the novel expansion agents are useful where shrinkage of the composition on drying has to be prevented or reduced.

Title: Improvements in or relating to level control apparatuses for digitally processed, low-frequency signals
IPC: H04B3/06
Filed: 1979-03-28
Abstract: A level-control apparatus for digitally processed low-frequency signals includes an intermediate circuit 16, 17, 18 which performs the digital processing. The intermediate in circuit 16, 17, 18 is driven at its maximum operating level by a variable gain amplifier 2, 3, 4. The controller 7 supplies a control voltage to the variable gain amplifier 2, 3, 4 for controlling its gain so that it supplies signals of a substantially constant level to the intermediate circuit 16, 17, 18. A control amplifier 20, 21, 22 is connected to the output 19 of the intermediate circuit 16, 17, 18. The gain of the control amplifier 20, 21, 22 is also controlled by the control voltage, but in such a way that its gain is inversely proportional to the gain of the variable gain amplifier 2, 3, 4. The envelope of the original signal is thus restored, while the intermediate circuit 16, 17, 18 operates at substantially its maximum level. <IMAGE>
