Abstract: 967,712. Continuous casting; swaging. SWISS ALUMINIUM Ltd. Aug. 15, 1963 [Aug. 15, 1962], No. 32325/63. Headings B3F and B3H. A machine for continuously casting metal strip or plate comprises a narrow rectangular mould formed with long sides 9, 10 and short sides 11, 12. A slotted nozzle in the casting chamber 6 is formed by inserts 15, 16 and extensions of the short sides 11 and 12. Spring means 13, 14 and 34 biases the side portions together and into contact with the inserts 15, 16 to ensure a liquidtight joint. The long sides 9, 10 of the mould are water-cooled and are divided into eight parallel segments. These long sides are moved simultaneously towards and away from one another by the action of cams on shafts 37, so that the casting gap periodically widens and narrows. Adjacent cams may be staggered so that adjacent mould segments perform opposing movements for a short part of the cycle. The cam-shafts are rotated synchronously and are connected that two opposite mould segments simultaneously move apart or towards one another. This action of the mould effects a kneading action on the solidified strip which is drawn out of the mould during the widening phase by rolls 36. The frequency of oscillation can be adjusted by a variable-speed drive to the cam-shafts 37. A further embodiment incorporates forging jaws 54 driven by cams and located adjacent the mould and includes automatic clamping means 56 for the strip 55 to permit movement of the strip in the casting direction only through the forging device.

Title: A corrector circuit for colour pyrometers
IPC: G01J5/60
Filed: 1961-09-12
Abstract: 993, 318. Radiation pyrometers. SIEMENS & HALSKE A.G. Sept. 12, 1961 [Sept. 16, 1960], No. 32648/61. Heading G1A. A colour pyrometer of the type comprising two measuring circuits for determining the ratio between the radiation intensities of two different wavelengths emitted from the test source after transformation into electrical quantities, incorporates a corrector circuit, wherein, to compensate for the variation of the emissivity of the source with the radiation wavelength, so as to be able to determine the true temperature TW of a wide variety of radiation sources, an auxiliary voltage of a fixed value, or varying with the measured value, is applied to at least one of the measuring circuits. Fig. 2 shows isotherms T 1 , T 2 , T 3  comparing the radiation intensities J (# 1 ) and J (# 2 ) of various substances having emissivities E 1 , E 2 , E 3  at temperatures T 1 , T 2 , T 3  and intersecting due to the variation in emissivity (Fig. 1, not shown), away from the origin at S. True temperatures T 1 , T 2,  T 3 , proportional to the slope of their isotherms are thus obtained by adding voltages representative of g and r to the electrical signals corresponding to intensities J (# 1 ) and J (# 2 ) or by adding a variable voltage representative of y = F (Tw) to the signal representative of J (# 1 ), and comparing the final signals. In the circuit shown in Fig. 3, voltages representative of g and r are applied by batteries B 1  and B 2  to the photo-cells Z 1  and Z 2 , detecting intensities J (# 1 ) and J (# 2 ) respectively, the resulting voltage of Z 1  being compared in amplifier V with the part of the resulting voltage of Z 2  across potentiometer R 4 , the servomotor M controlling the variable contact on R 4  to give a null reading, the position of the sliding contact then giving an indication of the true temperature Tw of the source. To give an auxiliary voltage corresponding to y = F (Tw) the voltage source B 1  may be omitted and the servomotor also control the auxiliary voltage applied by source B 2 . Alternatively the two photo-cells may be connected in series parallel with the associated auxiliary voltage sources, to supply one half each of a direct reading quotient measuring arrangement, Fig. 5 (not shown).

Filed: 1928-11-09
Abstract: 301,385. Maschinenfabrik Oerlikon. Nov. 28, 1927, [Convention date]. Driving-arrangements; stop apparatus, non- automatic.-In a jockey pulley drive, particulady for ring spinning and doubling frames, wherein the machine is started and stopped by tightening and slackening the driving-belt, a brake is provided between the device for applying and releasing the load effecting the tensioning of the belt and the operating hand-lever so as to prevent abrupt action in the event of the hand-lever being prematurely released. The driving-belt 7 is tensioned by a pulley 3 pivoted on a stud 1 and connected to a weight 6 by a chain 4 passing over a sprocket-wheel 5 fast with a ratchet wheel 9 on a stud 2. The pawl 10 of the ratchet wheel 9 is mounted in an arm 12 connected by a link 26 with the shorter arm of the operating hand-lever 20, which is mounted on the stud 1 and carries a pawl 23 adapted to engage a ratchet wheel 22. The lever 20 is arranged between a collar 27 on the stud 1 and the ratchet wheel 22, which bears against a leather washer 29 pressed by a spring 28 adjustable by a nut 30. To release the tension on the belt 7 the handle 20 is moved in the direction of the arrow, whereupon a stop 15, Fig. 4, on a disc 13 on the stud 2 is disengaged from an abutment 31 on the rod 26, and the pawl 10 is thereby released from an abutment 14 on the disc 13 and, by means of a spring 19, engages and operates the ratchet wheel 9 and with it the sprocket wheel 5 so as to raise the weight 6. Movement of the lever 20 in the reverse direction raises the pawl 10 and allows the weight 6 to be again operative, the leather washer 29 preventing abrupt action should the lever 20 be prematurely released. The lever 20 may be held in its extreme positions by detent devices. If the arrangement is applied to a stepped pulley multispeed drive the members above described are mounted on sleeves slidable on the studs 1, 2.

Abstract: 1534461 Remote measurement of radiation ELECTRIC POWER RESEARCH INSTITUTE Inc 5 Aug 1977 [30 Sept 1976] 32866/77 Heading G1A [Also in Division H4] Radio-activity is measured by a detector, such as a scintillation counter 14, producing a voltage proportional to the radiation energy; the detector signal is amplified, converted to serial digital form, and then converted to tones by a modem 20 for transmission via a telephone mouthpiece 22. The transmitted signals are passed via receiver 26 to modem 30 for conversion back to serial digital form, and thence via D/A converter to a pulse height analyzer 34. The energy spectrum of radiation source is split into 256 levels, each of which is represented by a 10 bit word, one bit being for a parity check and another for synchronizing modem 30; about 120 levels can be transmitted per second on normal telephone equipment, which is less than the maximum information rate that analyzer 34 can handle. The analyzer can therefore be used to analyze the radiation from several sources simultaneously by duplicating parts 14-32.

Abstract: 760,712. Colour television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 8, 1954 [Nov. 26, 1953), No. 32912/53. Class 40 (3). A colour television service comprises at least one transmitter producing a transmission of the type shown in Fig. 1(a) in which a chrominance signal is conveyed by a sub-carrier 20 so as to occupy a band falling outside the band of the luminance signal 19 conveyed by a main carrier 18, together with at least one further transmitter producing a transmission of the type shown in Fig. 1(b) in which the chrominance signal is conveyed by a sub-carrier 20 so as to occupy a band falling within the band of the luminance signal 19, the spacing between the two carriers 18, 20 being the same (2.6 Mc/s.) in each case. The service then includes receivers which with simple switching may be set up to receive either type of transmission. Fig. 1 shows typical frequencies, the band width of the chrominance signal in the case of Fig. 1(a) being slightly wider than that in Fig. 1(b) and permitting symmetrical side-band transmission. The chrominance signals comprise I and Q modulations of the sub-carrier at 90 degree phase points in accordance with the American N.T.S.C. standards. In the receiver, Fig. 2, received signals are reduced to a common intermediate frequency and the output from the I.F. amplifier 26 applied to two amplifier channels 29, 30. Channel 29 has a pass band as shown in curve (e) and channel 30 has a pass band as shown in (d). Each channel includes a second detector 34, 49. To receive a transmission of the type shown in Fig. 1(b), switches 31-33 are placed in the positions shown. Channel 30 then becomes ineffective and the output comprising the luminance and chrominance signals is derived through channel 29. The luminance signal passes through amplifier 35, a low pass filter of for example 0-2.3 Mc/s. and switch 33 to matrix unit 38. The chrominance signal passes through amplifier 36 and band pass filter 39 of 1.6-3.0 Mc/s. pass band to a synchronous demodulator 40 supplied with 0 degree and 90 degree phased signals of sub-carrier frequency (2.6 Mc/s.) from source 43. Demodulation is effected in the conventional manner and the resultant I and Q signals are then combined with the luminance signal in the matrix unit to derive the component colour signals for application to individual cathode-ray tubes 45-47. To receive a transmission of the type shown in Fig. 1(a), the switches are placed in their alternative positions. The luminance signal is now applied to the matrix without restriction in band width and the luminance signal derived through channel 30 and filter 50 which is of increased band width, 1.6-3.6 Mc/s., to accommodate the wider transmission.
