IPC: D01F13/02
Filed: 1950-01-03
Abstract: <PICT:0672314/IV (a)/1> <PICT:0672314/IV (a)/2> Apparatus for continuously forming and treating filaments, yarns, films, bands, or other articles or products from viscose, is provided with means for entrapping gases comprising a hood adapted to cover part or all of the forming and treating devices, a liquid seal to receive the hood, means for raising and lowering the hood, a fixed ventilating shaft passing through a duct formed in the hood, and means for drawing gases into the ventilating shaft.  If desired a further, separate ventilating shaft may be provided, and the first ventilating shaft may be adapted to close automatically against communication with the hood when the latter is lowered and to open into communication therewith when the hood is raised.  As shown in Fig. 1, viscose is discharged into vat 1 from a hopper and is coagulated to form a film. The film is passed to a second vat 2 containing an acid bath, then into vat 3, and subsequent vats, containing a heated water bath, e.g. at 85-95 DEG  C.  Rollers 4, 5 are provided so that the film travels in a sinuous path.  A common trough 6 formed round the upper edge of the vats, contains water or other liquid.  A hood 7 is supported by a hydraulic jack 8 so as to overlie vats 2 and 3.  When hood 7 is lowered its free edge enters trough 6 and a liquid seal is formed. The hood is provided with a duct 9 which receives a ventilating shaft 10 with nozzles 11.  Valve 12 regulates the flow of gases and vapours through the shaft.  As shown in Fig. 3, p  suction may be applied to the vats both when the hood is open and when it is closed, the suction being greater when the hood is open.  Vat 14 is normally covered by hood 13 which dips into liquid seal 15.  A fixed ventilating shaft 16 is provided.  A fixed casing 17 is supported by cross-bars 18 and there is an additional shaft 19.  Casing 17 carries trough 20 which forms a liquid seal and into which flange 21 may enter when hood 13 is lowered.  When hood 13 is raised, after the suction in shaft 19 has been stopped, the seal at 20 is broken so that gases in the vat are drawn off through shaft 16.  Before raising the hood, its inner surface may be swept with an inert gas, e.g. nitrogen, to prevent air from forming explosive mixtures with gases rich in carbon disulphide.

Filed: 1972-01-04
Abstract: 1338201 AM/FM receiver GENERAL ELECTRIC CO 4 Jan 1972 [4 Jan 1971] 238/72 Headings H3R H3A and H3T A demodulator for A.M. or F.M. signals comprises: two amplifiers arranged as a multiplier 42; a first source 41 of constant amplitude waves connected to one input A,-A, of the multiplier, the waves being derived from a selected A.M. or F.M. signal and having a predetermined phase relation with the selected signal; a second source 43 of waves derived from the A.M. signal when selected, which waves contain the amplitude information and have zero crossings coincident with the waves derived from the first source for stripped carrier detection; a third source of waves 44 derived from the F.M. signal when selected, which waves differ from those of the first source by a frequency dependent parameter for product demodulation; and means 45 for selectively connecting either the second or third source to provide the second input, B,-B, to the multiplier. Received A.M. or F.M. signals are applied via respective A.M. or F.M. stages 24, 25, mixer 12 and I.F. filter 14 to I.F. amplifier 15, the last stage 41 of which always acts as a limiter to provide the constant amplitude signal to input, A,-A, of the multiplier 42. When A.M. mode is selected by switch 62, a first predetermined voltage is applied to the A.G.C. line which actuates electronic switches 34, 45 (and any others if required) to select the A.M. circuitry and also biases the I.F. amplifier stages 38, 39 so that amplifier 40 produces a linear output. In this mode, switch 45 enables circuit 43, the amplitude modulated output from 41 is applied to the input B,-B of multiplier 42, and a detected A.M. signal is fed from it to audio amplifier 17. When F.M. mode is selected, switch 62 applies a second predetermined voltage to the A.G.C. lines which actuates the electronic switches for F.M. reception, and changes the bias on I.F. stages 38, 39 so that amplifier 40 also produces a limited output. In this mode, switch 45 enables circuit 44 which contain selective circuits 54, 55 and a frequency dependent signal is applied to the B,-B input of multiplier 42. Circuit 42, 44 now function as a phase shift demodulator, to feed an audio signal to amplifier 17. The output from 42 also provides, after amplification in 19, an A.G.C. signal for amplifiers 38, 39. This signal is applied via network 58, 59, 60, 61 which provides fast acting A.G.C. during tuning and a long time constant when in tune.

Title: Roller leveling
IPC: B21D1/02
Filed: 1966-01-04
Abstract: 1,076,263. Straightening. MAUST MACHINERY CORPORATION. Jan. 4, 1966 [Feb. 3, 1965], No. 243/66. Heading B3E. A roller leveller comprises two opposed banks of work rolls, the rolls in the first bank being in spaced staggered relation to the rolls in the second bank for flexing beyond its yield point, strip material passing between the banks of rolls, said rolls being divided into a plurality of separate roll clusters, each cluster including at least two rolls, and drive means inter-conhecting the rolls in each cluster, the rolls of one cluster being rotatable at a different speed from the rolls in an adjacent cluster. Each cluster may comprise two rolls, e.g. 11, 12, of one bank and one roll, e.g. 18, of the other bank which rolls and their backing rolls are geared together, suitably so that the rolls 11, 12, 18 all rotate at the same speed. In operation, strip 1 is pulled through the leveller rotating the rolls in its passage therethrough. Owing to slight elongation in the strip consequent on the flexing, each cluster is rotated at a speed slightly greater than that of the preceding cluster. Adjacent clusters may be geared together through an overrunning clutch, Figs. 5, 6, 11 (not shown), and a drive provided to assist in overcoming friction so that all the rolls are driven at a predetermined minimum speed, e.g. the speed of the first work roll at the entry to the leveller. Each cluster may comprise one roll from each bank, two rolls from each bank, two horizontally adjacent rolls in one bank, or two rolls in one bank and their backing rolls. To clean the work rolls they may be driven through stub shafts (76), Fig. 4 (not shown), one to each cluster at a speed to cause slippage between the strip and the rolls. Each cluster may be positively driven during levelling.

Abstract: 1,022,414. Advancing mine roof supports. COAL INDUSTRY (PATENTS) Ltd. Jan. 1, 1963 [Jan. 4, 1962], No. 432/62. Heading F1P. In an electrical system, Figs. 1 and 2 (not shown), for an hydraulic mine roof support system wherein electrical signals can be received from and/or transmitted to a plurality of roof supports arranged to be operated in a predetermined sequence through signalling conductors, the contacts of a relay A in each circuit associated with a particular support is arranged on receipt of a signal to connect the signalling conductors to the electrohydaulic valves of the appropriate roof support, each circuit being such that when its relay is actuated a voltage pulse is developed thereby and is passed along a linking line c to the circuit associated with the next roof support in the sequence whereby the relay A associated therewith is actuated. By appropriate switching at a control station potentials are applied to the signalling conductors which cause the electrohydraulic valves to operate and hence the associated roof support. The valves may be arranged as described in Specification 967,164. The system consists of a chain of identical operating circuits S1, S2 . . . (Fig. 2) connected by an earth line b, a D.C. power supply line a, and the linking line c to each other and to a control station CS. In operation the D.C. supply is fed to one end of the line a and a positive voltage pulse is applied to the opposite end of the linking line c so that the end circuit (S, in Fig. 2) is operated, a bridge formation of diodes B prevents operation of other circuits. The relay A in the operated circuit is therefore actuated. A very short negative pulse is then generated by a stepping pulse generating circuit SPG having a mechanical make-and-break stepping contact MSC such as a telephone dial, manual, button or relay contact and used to initiate the pulse. The negative pulse is applied to the line a whereby a transistor TI in the operated circuit is caused to conduct thereby de-energizing the relay A therein and producing a positive pulse which is passed to the next operating circuit through the linking line c to cause the relay A in the circuit S2 to be energized. Further short negative pulses operate successive circuits in sequence and a series of relay contacts A1 in the line a are each operated by their corresponding relay A to ensure that preceding circuits in the sequence are not operated. A switch DS in the control station CS allows circuits to be operated in sequence in the reverse direction.
