Title: Electrical autopilot apparatus for ships
IPC: B63H25/04
Filed: 1969-10-29
Abstract: 1,245,066. Automatic steering control. TOKYO KEIKI K.K. Oct.29, 1969 [Nov.1, 1968], No.53014/69. Heading G3R. In a ship steering system the output of an erroractuated positional follow-up servosystem responsive to a computer calculating the desired course of the ship is automatically prevented from being applied to an electrical automatic pilot unless the error signal of said servosystem is zero. In Fig.3, a digital computer 1 calculates the desired course of a ship from such factors as ship's position, loading, crew management, body stress, etc. A digital signal at 2, corresponding to the course, controls a servomotor 5 2  which, by virtue of positional feedback through an analogue to digital converter 6-3 sets an electrical transmitter 7 to a position corresponding to the desired course. When the signal controlling the servomotor is zero, indicating true follow-up, a switch 8 closes so that the signal from transmitter 7 adjusts an autopilot 9 to set the ship on the desired course. Changes of course due to transients or transmission faults are thus avoided. Use of an analogue computer instead of a digital computer is described.

A spool valve for controlling hydraulic flow between pump 7, reservoir R and motor 6 is arranged to maintain a constant flow rate to the selected end of the motor which is determined solely by the direction and amount of movement imparted to the spool. Land 25 has tapered grooves 30, 31 which throttle flow between inlet passage 10 and feeder passage 11 in accordance with the degree of movement of the spool, and the pressures in these passages are communicated to opposite sides of a piston closure member 34 which is urged to the " open " position shown by a spring 40. In operation pressure fluctuations in passage 10 change the pressure drop across the operative groove 30 or 31 so causing member 34 to move to a position to maintain a constant rate of flow to the selected service passage 15 or 16 via load holding check valve 14. A similar arrangement, comprising groove 43 and closure member 48, regulates exhaust flow from outlet 42. Figs. 2-7 (not shown) illustrate modified arrange ments for achieving a constant flow rate.

Abstract: 1,162,356. Tunnel ovens. ETAB. FRINGAND S.a.r.l. 14 Dec., 1966, No. 55989/66. Heading A2A. A tunnel oven for baking pieces of dough into rusks, pastry and bread, e.g. Viennese bread, comprises a first baking chamber having, for example, an entrance gate A, and a second or final baking chamber (not fully illustrated in the drawings. The pieces of dough are fed, e.g. through the gate A, on to the upper flight of an endless, travelling conveyer belt 15, which carries them through the first and second baking chambers, and then discharges the baked products, e.g. through an outlet gate (not shown). An operating turbine-fan 3 draws hot combustion gases from a burner 1 and its associated combustion chamber 2, and feeds these hot gases, through a distributing box 4 and hearth channels 5, into a collecting box 6. From the box 6, the gases pass, through a sheath duct 7, an upper distributing box 8 and upper vault channels 9, into an upper collecting box 10, in which means, such as a flap-valve, is provided to pass a desired fraction of the returning, slightly cooled gases, through another turbine-fan 12 and a sheath duct 11, into the combustion chamber 2 where they mix with fresh, hot combustion gases from the burner 1. The resulting mixture of hot gases is circulated, as described above, to heat the first baking chamber, into which steam may be injected in a conventional manner. The remaining fraction of said returning slightly cooled gases is discharged through a chimney 14 having a flap-valve at its base.

Title: Vehicle braking control

Filed: 1972-12-05
Abstract: 1385278 Anti-skid brake control systems SOC ANON AUTOMOBILES CITROEN 5 Dec 1972 [13 Dec 1971]. 55993/72 Heading F2F An anti-skid brake control system for at least one wheel comprises an electrically operated valve delivering a braking pressure proportional to a control signal delivered to a winding of the valve by a device which produces a pulsed signal according to wheel slip, the valve having a sliding member controlled by delivery side pressure and actuation of the winding to close off pressure delivery to the brake and by a spring to open such delivery. Wheel speed is detected by a magnetic pulse generator 27, the output of which being converted to voltage amplitude by a converter 28; alternatively, a tachogenerator may be used. A comparator 29 compares this signal with that from a generator 30 supplying a reference voltage representing a fraction of the vehicle speed for optimum wheel slip. This is obtained from an unbraked wheel or by deceleration measurement and subsequent integration. The comparator output is fed to a second comparator 32 which also accepts a sawtooth input from a generator 31. The output produced from a succeeding flip-flop 33 is of pulses of fixed frequency but having varying duration according to the wheel speed. These pulses are amplified at 34 and pass to the winding 24 carried on a cup member 26 between the spring 19 and one end of the valve member 10. The winding 24 is located in an annular gap 23 between a polepiece 21 and a pot-shaped yoke 22 carrying a permanent magnet 20. Actuation of the winding 24 opposes the spring 19 to allow fluid pressure on the delivery side of the member 10 in a chamber 17 to act on a needle 16, abutting the member, to raise the member to cutoff fluid flow from a pedal operated valve 6 and allow flow from the brake to a reservoir 8 until the needle force is decreased to balance the forces on the member 10. A system for four wheels has a valve for each of two wheel pairs, front and rear. Speed sensors supply signals to a comparator which selects the fastest speed for the reference signal and applies a slip factor to this signal which is fed to a common reference generator for both wheel pairs. The comparator, for each wheel pair, feeds the slower speed signal to a second comparator for actual/reference speed comparison the output of which is fed to a sawtooth signal comparator and thus to the valve as before. For the rear wheels, the sawtooth signal comparator, the flip-flop, and the amplifier may be replaced by a threshold value circuit which supplies a signal to the winding as soon as slip or deceleration of the slower wheel attains a predetermined value. Known circuitry may be included to limit the rear wheels' braking, pressure with respect to static and dynamic loading of the rear axle..The signal to the valve(s) may be of fixed duration but having a varying frequency.
