Title: Process and apparatus for regenerated cellulose film production
IPC: B29C48/08
Filed: 1958-10-01
Abstract: <PICT:0852614/IV(a)/1> <PICT:0852614/IV(a)/2> <PICT:0852614/IV(a)/3> <PICT:0852614/IV(a)/4> <PICT:0852614/IV(a)/5> <PICT:0852614/IV(a)/6> <PICT:0852614/IV(a)/7> <PICT:0852614/IV(a)/8> Regenerated cellulose film is made by extruding a cellulose solution into contact with a liqud coagulant, continuously drawing the freshly extruded gel film, until it is substantially completely coagulated, in contact with a limited quantity of the liquid coagulant which has been applied to a moving endless belt and is being carried by said belt through the air, while avoiding contact of the gel film with the belt, completing regeneration of the cellulose, and washing.  Preferably the cellulose solution is viscose and the liquid coagulant an acid-sulphate bath. The belt may be driven at a linear speed of about 80-125% preferably approximately 80%, of the speed of drawing the film, which is preferably drawn independently of the belt drive.  The film may be extruded into a bath from which it is taken into contact with the liquid coagulant on the belt and from which the belt draws its liquid.  Apparatus as shown comprises means for extruding film, 12, a vessel for liquid coagulant 14 an endless driven belt 17 disposed so as to convey coagulant thereon through the air, and means independent of the belt drive (e.g. driven roll 56) to draw the film over the belt and in contact with the liquid coagulant thereon (see inset, Fig. 1, indicating relative positions of gel film 10, layer of coagulant 13 and belt 17).  Preferably the belt is so disposed with reference to the vessel that when driven it conveys liquid from the vessel on to a substantially horizontal rim of the belt, and the upper conveying portion of the belt is not submerged below the level of coagulant in the vessel.  As shown, means may be provided in the vessel so that the film in the initial stages of its path is secluded from the main body of liquid in the vessel.  Figs. 3-8 illustrate methods of limiting bath turbulance in the film extrusion region or of limiting the distance the freshly extruded film must travel before reaching the moving belt.  Specification 852,609 is referred to.

Abstract: 855,970. Electric tests. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Oct. 11, 1957 [Oct. 15, 1956], No. 31820/57. Class 37 In a circuit breaker testing arrangement of the type in which separate high current and high voltage supplies are provided, the alternating high current supply is full-wave rectified in an inductive current the two separate half-waves so overlapping that the current through the breaker does not fall to zero until the contacts are sufficiently open for the re-striking voltage to be applied. In the arrangement shown, the D.C. current through the breaker under test is supplied from the centre-tapped secondary of transformer T the primary of which is supplied from short circuit generator G. Current transformers W1, W2 control the period conductivity of rectifiers V1, V2. The inductance in the rectifier circuits prevents the current from rising and falling instantly so that both rectifier anodes carry current for a time and the total breaker current never falls to zero. Initially the rectifiers may be switched - when the current is zero by a starting impulse derived from a small generator on the shaft of the short circuit generator G. The high voltage current comprises capacitor C charged from a high voltage D.C. source spark gap F, reactor Ls and r-c circuit Rd Cd in parallel with the breaker and acting to adjust the frequency of the voltage and to damp the transient recovery voltage. In the arrangement of Fig. 3. the use of a special rectifier transformer is avoided by the arrangement shown in which the primary of each of transformers T1, T2 is amended in parallel with two phases of generator G.

Title: Improvements in or relating to programme controllers or the like
IPC: G05B19/12
Filed: 1958-10-07
Abstract: 892,374. Programmed electric control systems. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Oct. 7, 1958 [Oct. 8, 1957], No. 32009/58. Class 38 (6). In a programme control of the kind in which a follow-up switch unit follows the displacement of a line on a moving chart and normally remain to one side of the line, an additional switch is provided to prevent ambiguous operation if the unit should move through the line and out the other side. In one embodiment, the temperature of an electric furnace 8 is controlled with respect to time in accordance with the position of a conductive line drawn on a moving chart 4 which itself passes over an electrically-conductive plate. A unit 7 which moves across the chart in response to furnace temperature carries two capacity sensitive probes 1 and 2 which actuate relays 6 and 5. The main probe 2 closes contacts 10 of relay 5 to energize the furnace 8 whenever the probe moves on to the line, and the resetting rise in furnace temperature should restore the probe to the position shown whereupon the contacts 10 re-open. If, however, the unit 7 continues to move downwards, the auxiliary probe 1 reaches the line and energizes relay 14 over contacts 12 in relay 6. Relay 14 holds in over self-holding contacts 16 to ensure that the furnace remains energized over contacts 17 regardless of any further downward movement of the unit 7 which could bring either or both the probes 1 and 2 beyond the line on the wrong side. When the unit 7 eventually rises sufficiently for the auxiliary probe 1 to clear the line, relay 6 is released to close contacts 13, and since probe 2 will now be on the line, contacts 11 are closed and the coil of relay 14 is shunted to release the relay. In a modification, Fig. 2 (not shown), two conducting probes are used to control a pair of relays in a similar manner to the capacitative probes. It is also stated that electromagnetic, photoelectric, or radio-activity sensitive probes may be used with appropriate guide lines, and that the chart movement may be made in accordance with pressure or pH value instead of time.

Title: Process and means for controlling the sludging of steam boilers
IPC: F22B37/56
Filed: 1930-10-24
Abstract: 366,113. Electrically and thermally actuated valves. HÍHL, K., Kulmbach, Blaich, Bavaria, Germany. Oct. 24, 1930, No. 32060. [Class 135.] A boiler sludge valve 5, Fig. 2, is mechanically or electrically locked in its open position until a recorder 34 indicating the sludging is actuated. When the sludge valve is opened, a contact plate 23 on the valve spindle completes an electric circuit 26 through an electromagnet 25, which keeps the valve in its open position. The heat sensitive element 3 in a tube 38 inserted in the sludge pipe 1 expands upon the discharge of the hot sludge and raises a piston 41, Fig. 3, carrying contacts 40 which complete a circuit 33 through the recorder. An electromagnet 27 in the circuit 33 then attracts a spring contact 28 in the circuit 26, thus de-energizing the magnet 25 and allowing the sludge valve to close. Further expansion of the heat sensitive element presses the end of the rod 51 raising the piston 41 through a hole in the piston and allows it drop. The position of the heat sensitive element is adjusted by a screwed pin 45 projecting through the bottom of the tube 38. The sludge valve may be maintained in its open position by a pivoted arm 64, Fig. 9, locked by a pin 67. The head 70 of the rod 51 of the heat sensitive element operates the recorder 69 through a rod 71, and at the same time rocks a lever 74, which contacts with the end of the locking pin 67 to move it inwards against the pressure of a spring 77. The pivoted arm 64 is then turned by a spring and closes the sludge valve. The heat sensitive element may be arranged in the spindle of the sludge valve.

Abstract: 601,799. Angular bending. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK DU CROO & BRAUNS. Nov. 29, 1945, No. 32291. Convention date, Dec. 11, 1939. [Class 83 (iv)] In a method of bending girders and like beams, the work is supported at two points and pressure is applied at at least two other points between the supports, the proportion of the pressure at the two or more points being maintained constant. The beam 1, Fig. 2, is supported at 2 and pressure is applied at the points 5 of an equalizer 4 by a hydraulicallyoperated jack 3. In a modification, two hydraulic jacks operate directly on the surface of the work and are controlled by a single pump. In a further embodiment, Fig. 4, pressure is applied at four points 5 through two jacks 7, each acting on an equalizer 4 and supplied by the same pump. In a modification, four-point pressure is applied by four jacks 7 fed from a common pump. In yet another embodiment, the girder &c. is horizontally supported between lateral guides 9, Fig. 6a, which prevent warping and in addition to the four points 5, pressure is applied midway at point 8 to compensate for the influence in bending due to the weight of the girder itself. The resultant bending moment stress distribution diagram is shown at Fig. 6b.
