Filed: 1976-01-29
Abstract: 1526343 Mooring ships IMODCO Inc 29 Jan 1976 [30 Jan 1975] 3611/76 Heading B7S [Also in Division G1] A mooring system for a ship comprises a mooring arm 10 (Fig. 2) to which a ship may be tied by means of a hawser 20, strain gauges 22, 24 for generating an output signal indicative of the strain in the arm, means for establishing a reference signal and means for comparing the strain gauge signal with the reference signal for generating a warning signal when the strain gauge signal level equals or exceeds that of the reference signal. The strain gauge signal may be compared with the reference signals and the warning signal generated by apparatus (Fig. 3) situated on a buoy 12 (Fig. 2) to which, the ship is moored. The buoy may also contain apparatus (Fig. 3) for recording the strain gauge signal, audio and visual warning devices operated by the warning signal and a transmitter for transmitting the warning signal to a receiver on board the ship on which may be situated a warning indicator responsive to the recieved signal. A similar reciever and warning indicator may be located on shore. The warning devices and warning indicators may be provided with time delay devices to ensure that the warning devices and indicators operate for a given period even if their activation is due to a transient warning signal. Two reference signals may be generated and each warning device may be so arranged that it gives a different type of warning according to which of the reference signal levels is equalled or exceeded by the strain gauge signal. In an alternative arrangement, (Fig. 4, not shown) the strain gauge signal is transmitted from the buoy and received on board the ship where the warning signal is generated. The mooring arm 10 (Fig. 2) may be pivotally connected to a post 14 mounted on a rotatable platform 18.

Title: Process and apparatus for degreasing wool with solvents
IPC: D01B3/04
Filed: 1932-02-08
Abstract: <PICT:0391929/III/1> In a process for degreasing wool and other fibrous or textile materials, especially wool bales, a volatile solvent is regurgitated through the wool contained in a closed vessel, the saturated solvent is then withdrawn, and the wool is freed from residual solvent by evaporation into a condenser maintained at low temperature and pressure.  In a suitable apparatus, an extraction chamber A contains a bag C made of flexible material, such as heavy canvas coated with cellulose dope, the open end of which is secured to the frame of a door B.  A pipe E is mounted on the door B and is connected to a vacuum pump F, and through two pipes G, H to solvent tanks J, K, a still L, and a low pressure condenser M.  In operation, the bag C is filled with wool bales, the door B is closed, and the chamber A is evacuated through the pump F.  Partly used solvent, e.g. benzene, is then admitted from tank J heated to 50 DEG  C., and the space between the bag C and chamber walls is filled with water under pressure, led in through a pipe D, whereby the bag is collapsed on the bales forcing the solvent there-through.  Water pressure is then withdrawn and process repeated, whereby solvent surges into and out of the wool. Saturated solvent is then withdrawn from the vessel A, and clean warm solvent is admitted from the tank. After extraction the solvent is forced through the pipe G into the tank J, and the saturated solvent passes to the still L from which solvent vapours pass through an ejector O into a condenser R and to the tank K. The wool bales are then freed from residual solvent by connecting the chamber A with the condenser M which is kept at a temperature of 5 DEG  C. and under low pressure, whereby solvent distils from the warm bales to the condenser.  Steam may be admitted to the chamber A to remove final traces of solvent.  Benzene may be replaced by trichlorethylene, or, when treating damp wool, acetone may be used in which case the low pressure condenser M is maintained at a sufficiently low temperature by artificial refrigeration.

Title: Improvements in relay mechanism for use in indicating and/or recording apparatus
IPC: G01K7/12
Filed: 1930-08-29
Abstract: 368,353. Relay devices. HODGSON, J. L., IVANOFF, A., and HOWARD, G. P. E., Biscot Road Works, Luton. Aug. 29, 1930, No. 4146/32. Divided on 368,273, [Group XXIX]. [Class 118 (ii).] In relay mechanism for indicating and recording temperature, for example that of a circulating fluid using thermocouples combined with a potentiometer device, the galvanometer needle is periodically clamped to a drum bearing the potentiometer slide wire, and returned therewith to normal corresponding to the potentiometer balance position, the temperature being recorded on a suitably calibrated moving chart by a pen the movements of which follow those of the drum. The slide wire 1<1>, Fig. 6, is mounted on a drum 7, Fig. 5, rotatable about and slidable along its vertical axis. Above, and concentric therewith rotates the galvanometer needle 5 suspended on hooks 6. A shaft 14 driven at constant speed from an electric motor 15 bears a cam 13, Fig. 5, which at every revolution (20 seconds) engages a lever 10, 12, pivoted at 12<1> to raise the drum 7, lift the needle off its suspension hooks 6, and clamp it between the drum 7 and a ring 8. The potentiometer slider is carried by a parallelogram linkwork to prevent unnecessary rubbing of the slide wire as the latter is raised or lowered. Further cams on shaft 14, now rock two levers 26, 29 pivoted on a shaft 28, Figs. 1 and 5, and through links 30, cause arms 16, 17 pivoted at 18, Fig. 5, to rotate, one of which, depending on the direction of deflection from normal of the needle 5, will engage the latter, and return it together with the drum to normal, in which position the potentiometer is balanced. The lever 10, 12 then allows the drum to fall releasing the needle 5 which again takes up a position corresponding to the temperature in readiness for the next clamping operation. The drum drives through gearing 69, 68 a pulley 67, carrying a cable 66 to actuate a pen to record the temperature on a chart 65 driven by the motor 15. The resistances R<1>, R1<1>, R2<1>, R3, R5 of the potentiometer device, Fig. 6, are of constantin, but R4 is made of nickel to compensate for variations in the temperature of the cold junctions which are brought adjacent thereto by compensating leads L of the same material as the thermocouples 2. A variable resistance B is provided for initially balancing the voltage across the bridge with a standard cell G which may be switched in for test purposes.

Title: Improvements in or relating to electric impulse generators
IPC: H04N5/06
Filed: 1944-03-08
Abstract: 577,710. Multivibrator oscillators; pulse modulation. NEWMAN, E. A. March 8, 1944, No. 4280. [Class 40 (v)] In an impulse generator, a condenser, charged from a source of potential, is associated with the grid of one valve of a multivibrator pair and through a rectifier with the cathode of the second valve, an impedance being arranged in the cathode circuit of the latter valve. The first valve is held non-conducting until the condenser charges to a certain potential when the two valves reverse their states due to the multivibrator action, the fall of cathode potential of the second valve causing the condenser to discharge. Assuming valve 2 cut off, the cathode being maintained near the potential of that of valve 8 due to the diode section conducting, condenser 1 charges over resistances 3, 4 until the grid potential rises sufficiently for anode current, to flow. The fall in anode potential is communicated over the coupling condenser to the grid of valve 8, the fall in cathode potential of valve 8 being fed back over coupling condenser 15 to lower the cathode potential of valve 2 increasing the anode current, thereby giving the rapid changeover action. Valve 8 being cut off, condenser 1 discharges over the diode section of valve 8 and cathode resistances 13, 14. The fall in grid potential of valve 2 causes a rise in anode potential and hence the grid potential of valve 8 until anode current flows, the rise in cathode potential being communicated over condenser 15 to the cathode of valve 2 to decrease further the anode current in valve 2. The valves are thus reversed again in their state to complete the cycle. Variable resistances 3, 4 and 14, controlling the charging and discharging of condenser 1, determine the duration of the negative and positive parts of the output waveform, while variations in the capacity of condenser 1 alter the duration of the cycle. In order to generate a train of impulses of constant duration, but having a repetition period varying in sympathy with a controlling frequency, the upper end of resistance 3 may be connected to a cathode follower, fed with a signal proportional to the difference between the variable frequency and the normal pulse repetition frequency.
