Title: Self-regulated drive apparatus for display systems
IPC: G09G3/28
Filed: 1973-05-22
Abstract: 1395122 Control of display BURROUGHS CORP 22 May 1973 [16 Nov 1972] 24452/73 Headings G4H and G5C Self-regulating drive apparatus for segmented electrode display devices includes input capacitors 210 and feedback resistors 230, 232, and a common biasing circuit for the segments whereby bias potential for cathodes 60 is developed across a common capacitor 270 charged by an amplifier 240, 250 responsive to feedback of the cathode drive currents, capacitor 270 being repetitively charged until the device fires. Capacitors 210 are at least partially discharged when the display is actuated and are recharged from capacitor 270 (via diodes 285), during intervals between input signals. The bias potential (and hence the operating voltage), adjusts automatically to compensate for potential threshold differences and for variations caused by changes in temperature &c.  The display device comprises cathode groups 60 forming 7-bar characters (Fig. 1, not shown), corresponding cathodes being connected to inputs 30A-30G connected via capacitors 210 to a data source 300. Each group has an anode 90 connected to a counter or register 200 which may be included in source 300. By means of the drive apparatus, electrodes 60, 90 can be sufficiently biased towards conduction that they can be operated by signals which do not exceed the maximum voltage excursions allowed on the outputs of MOS integrated circuits, which can thus be used for 200 and 300.

Title: Improvements in or relating to apparatus for controlling ship stabilising installations
IPC: B63B39/14
Filed: 1938-08-23
Abstract: 517,166. Automaticcontrol systems ; stabilizing ships. SIEMENS APPARATE UND MASCHINEN GES. Aug. 23, 1938, No. 24828. Convention date, Aug. 23, 1937. [Class 38 (iv), [Also in Groups XXXIII and XXXVIII] An arrangement for controlling ship stabilizing installations in accordance with the angle of list or roll of the vessel and if desired in accordance with the angular list velocity comprises a follow-up motor 1 having a large inertia and connected across two contact arms 13, 15, associated with a potentiometer 5, arm 13 being driven by the motor 1 and arm 15 by an angleof-roll indicator 7. The control dependent on the list angle is obtained from a rotary magnet 21 connected between the centre of the potentiometer 20 and an associated contact member 18, 19, operated by the motor 1. Further control in accordance with the angular list velocity may be obtained from a rotary magnet 22 connected across the contact arms 13, 15 and an additional controlling rotary magnet 25 may be provided energized in accordance with the angle of roll from a potentiometer 24 having its contact arm 23 operated by the indicator 7. The three rotary magnets may be replaced by a common rotary magnet. The potentiometers may be supplied with alternating current, the tapped-off voltages being supplied to primary windings of a transformer having a single secondary winding from which the composite control potential is obtained. Control of the tank stabilizing installation may be effected by controlling the angle of incidence of the propeller of a pump employed therein, the action of the rotary magnet being increased by a power amplifier and servomotor. In a modified arrangement. Fig. 4, two potentiometers 40, 41 having contact members 44, 45 operated through screwed spindles 51, 52 by an angle-ofroll indicator 48 are provided with further contact members 46, 47 operated by follow-up motors 42, 43 the damping of which can be varied electrically or mechanically and which are connected respectively across contact members 44, 46 and contact members 45, 47. The motor 42 also drives a contact arm 56 and has small inertia while motor 43, which has a large inertia, also drives a disc 58 carrying contacts with which the arm 56 co-operates to control electromagnets which control the stabilizing apparatus. The spindle 52 may be arranged to be driven rather more rapidly than the spindle 51 so that in addition to control of rolling, static list is also compensated for. The invention may be used for preventing pitching of a vessel. Specification 389,553, [Group XXXIII], is referred to.

Abstract: 838,479. Vibratory mechanisms. DUPOUY, V.G. B. Aug. 1. 1958 [Aug. 8, 1957; Nov. 7, 1957], No. 24871/58. Class 80 (4). A mass 1, Fig. 1, is vibrated by the rotation of a motor-driven shaft 3 carrying a balanced pair of diametrically-opposed chambers 5, 6, liquid being fed into one or other of the chambers during rotation to produce a variable degree of unbalance, and hence produce variable vibrations. The end 4 of the shaft 3 is hollow and has therein two circular channels 8, 10 of diametrically-opposed eccentricities, each channel 8 or 10 having a single radial hole facing the open end of a respective chamber 6 or 5. Two fixed pipes 12, 14, project through a support 23 into the hollow shaft end 4 with sufficient clearance for the vibrations, and have each an aperture opposite a respective channel 8, 10 so that liquid fed selectively through one or other pipe escapes into the appropriate channel and is then moved centrifugally through the radial hole into the appropriate chamber 6 or 5. In operation the shaft 3 is run up to the desired speed with the chambers empty and liquid is then fed into one chamber to give the desired vibrations. Liquid may subsequently be fed into the other chamber to reduce vibrations. The chambers 5, 6 have divergent mouths (Fig. 2), so that they drain when at rest. In a modification. Fig. 5 (not shown), the base of each chamber has a screwed plug and the pipes 12, 14 are provided with control valves. One of the plugs may have a bleed hole therein so that in operation liquid is continuously fed to this chamber and continuously escapes therefrom, the amount of out-of-balance being variable purely by operating one of the control valves. In another modification the two pipes 12, 14 are replaced by a single pipe 18, Fig. 3, which is moved axially in the support 23 to feed liquid selectively to the channels 8 or 10 from a reservoir 22 communicating with the pipe through radial bores. The end of the pipe is closed and provided with a hand grip 18a, the liquid flow being controlled by rotation thereof.

IPC: B63B1/24
Filed: 1955-08-30
Abstract: 774,854. Hydrofoil craft. SUPRAMAR AKT.-GES. Aug. 30, 1955, No. 24912/55. Class 113. In an arrangement for automatically controlling the lift of hydrofoils, the hydrofoils are vertically displaceable and an elastic element maintains the equilibrium of the lifting force in such manner that the hydrofoils, under the disturbing impulses acting on them when passing through waves, perform oscillations relatively to the hull and these oscillations act to control the adjustment of the pitch of the hydrofoils or pivotable flaps provided at the trailing edges thereof, the arrangement being such that the phase of the controlled alterations in lift at the hydrofoils is displaceable relatively to the phase of the control oscillations transmitted in accordance with the length of the waves. The hydrofoil 1 is attached to a frame 2 on a support 3 forming an assembly suspended on a shaft 4 from a lever 5 pivotally mounted at 6 to the boat. The hydrodynamic lifting force is balanced by an elastic element 9, which in Fig. 1 acts on the longer arm of the lever 5 and can have its tension modified by a hydraulic device 10, but could be located above the support 3 as shown at 9a, or could be a torsion spring on the axis 6 as in Fig. la. The hydrofoil assembly has a second link pivoted to the boat, namely an hydraulic device 7 connected to a part 8 of the support 3, so that the assembly is able to carry out free vertical movements. The oscillating movements are received at the lever 5 and transmitted through a rod 11 to an adjustable control device 12 which may be a time-delay relay, an impulse storage device, an electric or hydraulic phase-shifting device, a combination of resonance circuits, or one of the devices described in the Specification. From the device 12 the movements are transmitted with a phase displacement by a receiver element 13 to the valve 14 of the hydraulic device 14 which rocks the hydrofoil assembly about the axis of suspension 4 to change the pitch. In Fig. 1a the hydraulic device 7 actuates a pivoted flap 1a on the hydrofoil 1 and is connected to a second hydraulic device 15 controlled by the valve 14. Specification 745,821 is referred to.
