Title: Improvements in or relating to the stabilisation of ships
Inventor: BELL JOHN
IPC: G05D1/08
Filed: 1952-09-15
Abstract: 774,484. Automatic control systems for ships. MUIRHEAD & CO., Ltd. Sept. 11, 1953 [Sept. 15, 1952], No. 23131/52. Class 38 (4). In a system for automatically stabilizing a ship against rolling or pitching involving a control signal responsive to roll or pitch acceleration or rate of change of roll or pitch acceleration of the ship, a further control signal is introduced to eliminate the effect of roll or pitch acceleration or rate of change of roll or pitch acceleration produced by the stabilizing means. In Fig. 4 a fin 1, which is automatically controlled by means (not shown) to prevent rolling or pitching of a ship, operates a D.C. generator 2 producing a voltage dependent on fin velocity which applied to a modulator 4. The A.C. output of modulator 4 is applied to one winding of a variable inductive device 3 which is coupled to the fin so that a resultant output dependent on fin angle and velocity is obtained to control a repeater 6 operating an induction regulator 7. Induction regulator 7 is supplied with a voltage dependent on ship's speed and/or roll angle and/or roll velocity and/or roll acceleration. The output of induction regulator 7 is applied to a rectifier 8 associated with a delay network the output of which is utilized to control the fin. In a modification, Fig. 5 (not shown), the fin is adjusted by an hydraulic servomotor controlled by a pilot valve and an electric signal dependent on roll angle, velocity and acceleration, as in Specification 774,483, is modified by variable inductive devices, dependent on fin angle and velocity, and utilized to control the pilot valve. An arrangement in which there is no signal dependent on fin velocity is described and in this arrangement, to produce an electric signal dependent on fin angle, the fin operates a variable inductive device through a mechanical linkage which may be adjusted manually or automatically in dependence on ship's speed.

Title: Improvements in burner ignition control circuits
IPC: F23N5/08
Filed: 1964-06-04
Abstract: 1,033,226. Ignition control systems. CIE ELECTRO-MECANIQUE. June 4, 1964 [June 7, 1963; April 13, 1964], No. 23241/64. Heading F4T. A burner control system has a flame control relay 1 energized from supply points 17, 18 on closing the room thermostat 6, the relay 1 closing the contact 12 to energize the ignition transformer 13 for the burner, and closing contacts 9 to energize the motor relay 8. The motor relay 8 closes the contacts 14 to start the burner motor 15 and the contacts 11 to maintain the relay energized should the burner not light the heater 10 passing the motor relay current overheats and throws out the circuit-breaker 5. If the burner does light the sensor 2 decreases in resistance but the flame control relay 1 is not shunted since the relay 1 has opened the contacts 4 and a delay 3 such as a thermistor maintains the flame control relay 1 energized until the flame is up to temperature. When this state is reached the elements 3 and 2 shunt the relay 1 to deenergize it, the contacts 4 being made to allow the thermistor 3 to cool and leave the sensor 2 to cause actuation of the flame relay 1 again when the flame ceases. At the same time contacts 12 are opened to disconnect the ignition transformer although contacts 9 are opened the motor relay 7, 8 remains energized through the self-holding contacts 11. The delay 3 may be actuated by a thermal element of the circuit-breaker and the burner motor 15 may have starting and running windings.

Abstract: 914,635. Valve and transistor-gating circuits. FERRANTI Ltd. Oct. 8, 1959 [July 19, 1958], No. 23243/58. Class 40 (6). [Also in Groups XXXVIII and XXXIX] In a circuit for selectively energizing any one of a plurality of loads, e.g. magnetic recording heads or windings on magnetic storage cores, with current which may be selected to flow in either direction through the load, each load 11, Fig. 2, is connected to four terminals A, B, C, D by means of diodes so poled that current flows in one direction when a suitable energizing voltage is applied to terminals A, D and in the opposite direction when a suitable voltage is applied to the terminals B, C, the terminals A and D of all the loads being associated with each other in a first rectangular array 17, Fig. 1, the terminals A being arranged in a plurality of columns and the terminals D in a plurality of rows and the terminals B and C of all the loads being associated with each other in a second similar array 18 with the terminals B and C similarly grouped in columns and rows respectively, there being switching means such as a transistor or a thermionic valve associated with each column and row of both arrays so that by suitably energizing a pair of switching devices current may be made to flow in either direction in any selected one of the loads. In the arrangement illustrated in which the loads are constituted by magnetic recording heads, it is required to be able to energize any head, e.g. H1,1 with two successive oppositely directed current pulses to effect a recording thereby. In order to energize head H1,1 a row selection pulse is applied to the bases of transistors TD1, TC1 from load 26 1  simultaneously with a column selection pulse to the diode gates at the inputs to bases of transistors TA1, TB1, from lead 21 1 , these pulses covering the period including two successive information pulses applied respectively to leads 23 and 27 and to leads 33 and 37, thus permitting, firstly, current to flow between terminals D and A of head H1,1 and secondly, current to flow between terminals C and B of the same head. In order to use the heads for reading out, further read-out switches such as transistors RT1, RT2 &c. are provided, the desired head being selected by applying row and column selection pulses to the appropriate inputs 26, 21 and also applying a pulse to switch on the appropriate one of transistors RT1, RT2 &c. so producing a single current pulse flowing between terminals C and B of the chosen head. Discharge tubes such as triode valves may be used in place of transistors.

Abstract: 758,161. Electric control systems. FARBENFABRIKEN BAYER AKT.-GES. Aug. 10. 1954 [Aug. 17. 1953], No. 23250/54. Class 40(1) [Also in Group XIII] In a conveyer belt drier wherein moist material spread on the belt is dried by radiated heat, the material on the belt is preheated or precooled, and the resulting variations in temperature of the material are used to control the amount of radiated heat, and, if desired, the preheating or cooling. As shown, Figs. 1, 2, the material to be dried is spread by a distributer 4 on an endless travelling belt 1 and the terri- Derature of the material at its starting point on the belt is measured by a row of thermometers 5, Fig, 2. each of which is associated with a respective preheater 7 and thermometer 8 for controlling its respective radiant heater 11. Each thermometer 5 is screened at 6 from its associated preheater and each thermometer 8 is screened from its associated radiant heater 11. Each thermometer 8 measures rise in temperature due to preheating which depends on the moisture content and should this reach a predetermined value the circuit 9 is closed to short circuit the associated heater 7 and at the same time an electromagnetically operated valve 10 is released to stop the fuel supply to the associated drying element 11. which comprises a tube heated by combustion gases from a flame 12. The pre-heating coil 7 is switched in again, with the associated radiator tube 11, as the temperature at thermometer 8 falls, so that over a period the average heat radiated by the tubes 11 is proportional to the temperature rise due to preheating which is proportional to the initial moisture content of the material. Thermometers 15 screened from the radiators 11 serve to indicate the residual moisture content of the material at the exit point; and may be used to set the "limit" contacts of the thermometers 8. The drier chamber 16 is evacuated at 19 so that the material is drawn through the distributer 4 by suction. In a modification (Figs. 3, 4, not shown) the material is precooled by an air-blast or preheated by Suitable vapours and the radiators 11 are electric.

Title: Improved lifting and control means for platforms of stillage trucks
IPC: B62B3/06
Filed: 1944-11-25
Abstract: 584,349. Hand-trucks. HARRIS, C. W. Nov. 24, 1944, No. 23513. [Class 108 (i)] In elevating platform trucks, such as those described in Specification 554,260, in which the platform is supported from the lower carriage at one end by levers fulcrummed in the carriage, and at the other end by rollers running in tracks integral with the carriage, the platform being movable to an upper stable position by angular movement of the levers past the top dead centre position, the levers are formed as . cranks discs having internal teeth meshing with pinions mounted on' a shaft to which the elevating handle is connected by pawl and ratchet gear. As shown, the discs E are mounted on a shaft G in the lower carriage X and are pivoted to the platform F by a shaft P. Pinions K, meshing with internal teeth on the discs, are carried by a lay shaft J mounted in brackets J', fixed to a cross-member S of the lower carriage. The lifting handle H is pivoted on a pin L in a cage M freely mounted on the shaft J and is formed with a pawl N which engages a ratchet O keyed to the shaft. Upward and downward strokes of the handle H cause rotation of the ratchet O, pinions K and discs E to raise the platform until projections R on the discs contact the cross-member S. The shaft P is then positioned just past top dead centre so that the platform is stable and the lifting gear relieved of strain. A spring-loaded pawl Q mounted on the shaft G prevents running back of the ratchet during upward movement of the handle. The extent of movement of the handle is limited by the cross-member S and a stop U which contacts a forked extension of the cage M when the handle is in the vertical position. The stop may be turned through a right angle by a handle V to allow further upward movement of the handle. On movement of the handle past the vertical, the cage M contacts a pin W on the pawl Q to disengage it from the ratchet, and the handle contacts a cross-member F<1> on the platform to move the shaft P over the dead centre and allow descent of the platform under the control of a dashpot Z or a friction brake between the cage and ratchet adjustable by a bolt Y.

Title: Improvements relating to turbines and compressors
IPC: F01D11/12
Filed: 1956-08-02
Abstract: In an axial-flow turbine or axial-flow compressor the inner surface of the stator casing opposite the rotor blade tips is provided with a cylindrical layer of porous metal formed by sintering metal powder so that should the blade tips contact the surface of the stator in operation, the tips of the rotor blades will abrade the layer of porous metal.  To form the porous metal layer, nickel powder is sintered directly to the stator casing by the use of graphite or oxidized chrome steel moulds.  The porous nickel layer may subsequently be compressed and annealed to obtain the desired degree of porosity.  The casing may be formed of segments on each of which the metal powder is sintered before assembly; alternatively the porous metal layer may be formed on segments which are subsequently assembled within the stator casing.  The nickel powder may be 80 to 200 mesh powder, and the casing surface on which the layer is to be formed is preferably flash copper plated.  The casing with the nickel powder distributed thereon is heated to 2000 DEG F. for 20 to 60 minutes in a non-oxidizing or reducing atmosphere such as hydrogen. Subsequent annealing may be at a temperature of between 1500 DEG F. and 2000 DEG F.  Chromium, chromium-nickel mixtures or iron-nickel mixtures may be used instead of nickel.  If sintering temperatures of less than 1650 DEG F. to 1700 DEG F. are used, reduced size powder is used, but with higher temperature a wide range of particle size can be used.  Other sintering atmospheres referred to are de-hydrated incompletely burned natural gas, or carbon monoxide. A deposit of a phosphide of the metal powder being sintered may be formed on the casing by electroless plating before the sintering operation.  After cleaning and activating by electrolytic processes, the member on which the porous coating is to be formed is dipped into an electroless nickel bath where it is maintained for one hour at 190 DEG F,. the bath comprising sodium citrate, ammonium chloride, sodium hypophosphite, ammonium hydroxide and nickel chloride (NiCl2). Alternatively the electroless plate may be an iron phosphide, copper phosphide, silver phosphide or chromium phosphide by using suitable salts of these metals in the electroless plating solution.  The metal powder which is to be used for the sintering process may also be coated by electroless plate in a similar manner, the nickel powder, for example, being cleaned and activated and then stirred in an electroless nickel bath at 190 DEG F. for one hour. Each particle will then have a coating of the nickel phosphide.
