Title: Process for the continuous wet-treatment of textile ribbons or the like
IPC: D06B5/08
Filed: 1963-12-19
Abstract: 1,040,480. Treating textiles. ILMA INDUSTRIA LAVORAZIONE METALLI ANTICID S.a.S and GEIGY A.G. Dec. 19, 1963 [July 1, 1963], No. 50281/63. Heading D1L. A process for continuously wet-treating (e.g. dyeing) elongate textile material such as tops, card sliver, ribbons or fabric, comprises impregnating the material in at least one treatment bath, squeezing the material to expel excess liquid therefrom, subjecting the material to a thermal pre-treatment while free from contact with supporting or conveying means and finally completing the thermal treatment. As shown material A coming from at least one treatment bath has excess liquid expelled therefrom by rollers 10. It then passes downwardly through, but not in contact with, a duct 14 in which it is pre-heated. The duct 14 has perforated walls and is surrounded by an annular chamber C to which a heating fluid e.g. steam is fed via a duct 34. After being pre-heated the material falls in folds on a curved elbow piece 40 having a trap door 43 from which it slides on to a conveyer 44 driveable at an adjustable speed. The conveyer 44 lies in the main heat treating chamber D in which the heat treatment is completed. The chamber D is filled with water to a height governed by an overflow 88 and the water is heated by having steam passed therethrough from perforated steam pipes 85. Screens 90 are provided adjacent the roof of the chamber D to deflect drops of condensation. Inspection doors 92 are provided in the walls of the chamber. On leaving the conveyer 44 the material passes to a washing and sealing device F (see Fig. 3). The device F has a channel 66 to which water is pumped and from which water passes over a weir 68 to form a screen G which washes the material A and acts as a partial seal between the chamber D and the atmosphere. The water screen G runs to a tank 72 which is left at a constant level by a weir 56 over which water flows to a drain 78. The material is drawn through the device F by squeeze rollers 50. The entrance to the duct 14 is formed by converging plates 30 which may have slidable plates mounted therein to define an adjustable entrance slot; alternatively this entrance may be sealed by a pair of rollers. Further heating means may be provided in duct 14 and chamber D The whole of the heat treating apparatus is surrounded by insulation 22.

Filed: 1972-11-14
Abstract: 1385077 Timing igniton of internalcombustion engines ARVIN INDUSTRIES Inc 14 Nov 1972 [15 Nov 1971] 52516/72 Heading F1B An input is obtained from two pressure transducers 10 and 12 and a speed transducer 14. One of the pressure transducers 10 is mounted in the intake manifold of an internal combustion engine to sense the pressure differential between the atmosphere and the intake manifold. The other pressure transducer 12 is mounted to sense the pressure differential between the spark port in the engine carburetter and atmosphere. The engine speed is detected by a speed transducer 14 which is preferably a conventional pulse to D.C. level converter. The speed transducer 14 is connected to the centre distributer wire leading from the ignition coil. The outputs of the transducers 10, 12 and 14 are coupled to the respective analog signal function generator sections 16, 18 and 20. The outputs of these generator sections are summed together in a summing amplifier 22 together with the output of a command angle adjustment 24. The summation of the three generator section outputs enables one aggregate signal to be used to control the angular displacement of the distributer and thereby the timing of the engine. The command angle adjustment 24 is used to introduce any desired timing angle offset into the ignition timing characteristics. The summing amplifier 22 limits the total negative or positive command angle signals to a predetermined maximum amplitude and thus ensures that the ignition timing will not be excessively advanced or retarded. The output of the summer 22 is coupled to a servo-amplifier 26 to accordingly drive a servomotor 28 which is coupled, as by gears 29, to the top end or head of a distributer 30. The servomotor is also coupled by gears 31 to a feedback source potentiometer 32 or other feedback signal source. The polarity of the potentiometer output is inverted by an inverter 34 and thereafter applied to the input of the servo-amplifier 26 for altering the output of the amplifier 26 in accordance with the amount the distributer head is actually rotated compared with the angle through which it was commanded to rotate. Individual members shown in the block diagram of Fig. 1 are described in detail in the Specification.

Abstract: 1526880 Channel selecting apparatus with AFT SONY CORP 17 Dec 1976 [24 Dec 1975] 52741/76 Heading H3Q In a channel selector having the output of a reversible counter 40 connected by an A/D converter 90 to control an electronic tuner 100, first pulses A14 are selectively connectible to up or down inputs PU, PD of the counter and second pulses of lower frequency, such as from frequency divider 35, are selectively connectible to the up or down inputs of the counter by means of control signals EU, ED from an AFT circuit 120. A sweep generator 30 alters the count in counter under control of coarse up and down switches 31CU, 31CD or fine up and down switches 31FU, 31FD until the required TV channel picture is tuned. The AFT circuit 120 includes transistor differential amplifiers (122 and 123, Fig. 5, not shown). The contents of counter 40 can be read into a memory 50 by read/write circuit 60. The memory has non- volatile elements such as MNOS elements which retain their content when the memory is disconnected from the power supply. To select a stored channel a switch S1-S16 is operated which addresses the memory and the counter 40 is then set at the stored channel. If tuning deviation, as connected by AFT circuit 120, is more than a predetermined amount, determined by a counter 133, a signal PM from a memory rewrite circuit 130 operates instruction circuit 65 to write in the corrected binary count of the counter 40 into the memory 50 at the selected address. The AFT is disabled during tuning and when the power supply is first applied by a disabling signal PG obtained from a monostable multivibrator 142. The D/A converter 90 includes a pulse-width modulator (Fig. 3, not shown) which produces a chain of pulses the width of each of the pulses being dependent on the absence of coincidence between a channel identifying code B1-B14 (Fig. 4c, not shown) and a circulating digital code A1-A14 (Fig. 4B, not shown) from a timing counter 20. The output of the D/A converter 90 is fed via a LPF 92 to a variable capacitance diode of the electronic tuner 100. In a modified gate arrangement (Fig. 8, not shown) for the sweep generator 30 (150) the effects of the AFT circuit are overcome during up and down mound selection by switches (151 U and 151D) without disabling or disconnecting that circuit.
