Title: Signal Transmission Apparatus.
IPC: H04B3/11
Filed: 1966-07-28
Abstract: 1,154,594. Automatic volume control. WESTERN ELECTRIC CO., Inc. 28 July, 1966 [3 Aug., 1965], No. 33943/66. Heading H4R. In a transmission system including repeater amplifiers whose gain is dependent on the level of a pilot signal a repeater has means for determining the condition of the transmission path coupled to its output and for modifying the level of the pilot signal applied to its input. The system may be arranged so that if the attenuation of the path connected to the output of the repeater increases, e.g. due to temperature changes, the pilot level is reduced relative to the signal level at the input to the repeater and the repeater gain is therefore increased to compensate partly for the increased line attenuation. Fig. 1 shows a transmission system including repeaters 16, 17, and 38 whose gain is controlled by a pilot transmitted with the information signal. In order to compensate for temperature dependent attenuation changes in the line the temperature of the line is determined, e.g. as a function of the resistance of the temperature measuring cable pair 21 laid with the line. Prior to the first repeater the pilot and information signals are separated by filters 13 and 12 and the pilot signal is passed through a regulating arrangement which, by controlling the heating of thermistor 25 in accordacne with the current flowing in line 21, controls the level of the pilot signal in accordance with the resistance, and hence the temperature, of line 21. Due to this arrangement the pilot level at B is reduced as the attenuation of the line increases, repeaters 16 and 17 restore the pilot to its normal level, thus increasing the information signal above its normal level. Preferably the pilot level is changed by half the repeater section attenuation change, i.e. if the repeater section attenuation changes by 2dB the pilot level will change 1dB so that half the gain required to compensate the line attenuation change will be inserted at the repeater feeding the line. Prior to the last repeater the pilot and information signals will be separated with the information signals being fed straight to the repeater via filter 33 while the pilot signal will be separated by filter 36 from a signal from the regulating arrangement 37, which, by the control of the thermistor 40 whose element is connected in the negative feedback path of the amplifier 41 and whose heater is fed with a signal dependent on the current in line 21, will restore the pilot signal to its original level with regard to the information signals. The combined signal applied to point G will be restored to standard level in the repeater 38.

Title: Angle-measuring and drawing instrument
IPC: B43L7/04
Filed: 1933-12-04
Abstract: 413,943. Drawing-instruments. BADE, (nÚe NIETHAMMER), A., Oppendorfer Forsthaus, Schoenkirchan, Holstein, Germany. Dec. 4, 1933, No. 33988. Convention date, Jan. 13. [Class 97 (iii).] An instrument for drawing, hatching, measuring angles or for use with navigational charts has two pairs of rollers adapted to run in directions at right angles, one pair of rollers being lifted from the drawing surface when the other pair is depressed, and vice versa, and all or part of the remaining parts of the instrument being raised from the drawing surface upon depression of a pair of rollers. In the form shown, a flexible rule 1 which may have a leg 15 is attached to the bridge of a semicircular protractor 2. A plate 5 for carrying the rollers is slid over eye brackets 4, 4, on the bridge by means of corresponding oblong slots and is pivotally attached thereto by eye brackets 6, 6 and bolts 7, a space being left between the protractor and plate 5 so that the latter may see-saw about the bolts 7. The plate 5 carries a pair of rollers 9, 9 with their axle 11 mounted in bearing brackets 10 and a pair of rollers 12, 12 adapted to run in a direction at right angles to the rollers 9, 9, and each mounted on a journal 16 supported by a bearing bracket 13. A handle 8 is provided on the plate 5, so that the latter may be tilted to bring either pair of rollers into contact with the chart and simultaneously to raise the instrument from the drawing surface. The protractor 2 may be so connected to the rule 1 as to be capable of angular adjustment.

Title: Improvements in the dyeing of cellulose esters or ethers
IPC: C09B39/00
Filed: 1933-12-04
Abstract: Cellulose esters or ethers, dyeing; azo dyes, forming on the material; printing.--Dyeings readily dischargeable by reducing discharge agents are produced upon cellulose ester or ether fibres by applying thereto a diazotizable amine or aminoazo compound free from sulphonic acid groups, diazotizing the amine on the fibre and developing with a coupling component of the general formula <FORM:0413198/IV/1> wherein either (a) R1 is a residue of the benzene series and R2 is COOH, CO-NH2, CO-NH-Aryl or a carboxylic ester group, or (b) R1 is H, alkyl, or a carboxylic ester group and R2 is H, alkyl, a residue of the benzene series, CO-OH, CO-NH2, CO-NH-Aryl, or a carboxylic ester group.  Thus an acetate artificial silk may be entered into a bath containing the diazo component in dilute hydrochloric or formic acid and the temperature be slowly raised and maintained for \ba1/2\be--1 hour at 50--75 DEG  C. with an addition of sodium acetate; diazotization is then effected in a second bath and the development by treatment for \ba1/2\be--1 hour in a third bath at 50--75 DEG  C., neutral or weakly acid with acetic acid, containing the coupling component; alternatively the diazo component may be applied to the material in the form of a suspension or dispersion.  A table is given showing the tints of the dyeings with various combinations of components, specified diazo components being aminoazobenzene and 4-amino-3-methoxyazobenzene-3<1>-carboxylic acid and specified coupling components being the 1-phenyl-3-carboxylic acid methyl and ethyl esters, 1-phenyl-3-carboxylic acid amide and anilide, 3-methyl, 3-carboxylic acid, 3-carboxylic acid ethyl ester, 3-methyl-1-carboxylic acid ethyl ester, 1 : 3-dimethyl and 3-phenyl derivatives of 5-keto-4 : 5-dihydropyrazole.  Additional specified diazo components are dianisidine, tolidine, a - and b -naphthylamines, and p-nitraniline.  Specification 15059/14, [Class 15 (ii)], is referred to.

Title: Improvements in and relating to methods of shaping metal articles
IPC: B21K1/32
Filed: 1960-10-06
Abstract: 894,483. Making wheels; rolling; forging. REICHL, R. M. Oct. 6, 1960, No. 34243/60. Classes 83 (2) and 83 (4). A method of making a metal shape which has a thin web surrounded by a rim of substantially greater thickness than the web comprises forming a workpiece 10 with a thick web 11 surrounded by a rim 12 of greater thickness than and less diameter than the intended thickness and diameter of the finished metal shape, filling the space 14 and 15 beside the web with material 18 and 19 flush with the sides of the rim and confined by the rim, rolling the composite workpiece to a thinner section, then cross-rolling to a still thinner section and thereafter removing the filler material. Prior to rolling, the part 10 and the filler pieces 18 and 19, which may be of a related but less expensive material are heated separately. The filler pieces are heated to a lower temperature than the part 10 in order to present similar resistance to hot deformation. In a modification of the method the composite workpiece is heated to a uniform temperature and controlled cooling is then applied to the exposed faces of the filler pieces 18 and 19. Stop-weld may be used between the parts. The filler pieces are removed by drilling through each piece to the web, welding on an hydraulic coupling (Fig. 12) and forcing fluid in. Subsequently the rim only is forged, to remove any rounding of the edge, by dies 31 and 32 (Fig. 13). Shapes other than round may be produced by starting with a suitably forged workpiece blank and subjecting it to an appropriate rolling procedure.
