Title: Automatic control system
IPC: G05D23/22
Filed: 1960-07-12
Abstract: 955,976. Automatic control systems. LEEDS & NORTHRUP CO. July 12, 1960 [Sept. 14, 1959], No. 24324/60. Heading G3R. In an automatic control system for maintaining the magnitude of a condition at a selected value currents representing respectively the actual magnitude of the condition and the desired magnitude transverse a resistor in opposite senses and a final control element responsive to the potential difference across the resistor varies the magnitude of the condition in a direction to reduce the said potential difference to zero. As shown, a condition such as the temperature of a furnace 10 is detected by a thermocouple 11 connected to a voltage-to-current converter 12 the current output from which flows in a branch circuit including resistors 15 and 16. A second current derived from a supply 20 and an adjustable resistor 18 related to the desired furnace temperature and opposing the first current, is also passed through the resistor 15 so that the resulting potential difference E prop. across resistor 15 is proportional to the difference between the actual and desired values of the temperature, E prop. being zero when the temperature is at the set point. This deviation voltage, which has a polarity depending on which of the two currents traversing resistor 15 is the greater, is applied to the contact 46a of a vibrator 46 which is driven at a suitable frequency and which has another contact 46b connected to a negative feed back voltage derived from the input circuit of a magnetic amplifier 61 controlling energizing current for the heating resistor 37 of the furnace 10. Operation of the movable pole of vibrator 46 produces an output voltage having an alternating component proportional to the difference between the deviation voltage and the feedback voltage; this output is converted into a direct current by a circuit comprising amplifier 45, coupling transformer 48 and phase sensitive demodulator 49 and then applied to a transistor amplifying stage 50 feeding, over conductors 58, 57 and feedback resistor 60, the magnetic amplifier 61. The provision of the negative feedback voltage ensures that the output current in conductor 58 is maintained proportional in magnitude to the deviation voltage, and an adjustable resistor 66 is included in the feedback circuit to vary this proportionality. The system may include a rate action, there being provided a rate capacitor 39 and a rate resistor 40 which can be brought into circuit with the resistor 16 by closing a switch 38 whereby a voltage E rate, representative of the rate of change of the furnace temperature, together with the voltage E prop. appears at the contact 46a. The system may be used to control one condition having a predetermined relationship to another uncontrolled condition (Fig. 2, not shown), or may be cascaded to allow for fluctuations in the control agent, e.g. the heating resistor supply source, (Fig. 3, not shown). Specification 865,224 is referred to.

Title: Improvements in or relating to dynamo-electric machines
IPC: H02K23/26
Filed: 1929-08-09
Abstract: 334,042. Brown, S. G. Aug. 9, 1929. Windings.-To reduce the external magnetic field of a gramme ring wound generator or motor, such as a motor used for an aircraft turn indicator or for driving a gyro compass wheel, the windings of the ring are so arranged that their external sides in which current flows in opposite directions are brought into close proximity. The Figure shows an external-rotor motor with a 4-pole fixed internal magnet (shown in dotted lines) and with brushes 20 at right-angles on a diametrically cross-connected commutator 18. The current directions are indicated by dots and crosses for the case in which the upper brush is positive. The rotor has twelve inner tunnels I - - XII carrying the active conductors and six external slots 1 - - 6 carrying the idle conductors. Each external slot carries the external sides of two coils, viz. those of which the internal sides are separated by two others. Thus, the coils of tunnels II and V are carried in external slot 2 and so on. The result is that in each external slot the currents in the coil sides cancel each other magnetically. The same effect may be obtained, for example, by placing the coils of adjacent tunnels in the same slot, or by using any even fraction instead of one-half for the ratio of slots to tunnels.

Title: Improvements in or relating to methods and apparatus for detecting and/or measuring the concentration of oxygen in aqueous liquids such as boiler feed water
Inventor: DOWSON ARTHUR GORDON
IPC: D01H5/74
Filed: 1955-08-25
Abstract: <PICT:0806918/III/1> In a process for detecting and measuring the oxygen content of aqueous liquids (e.g. boiler feed water), the liquid is treated with an inert gas, and the gas (then containing absorbed oxygen) is brought into contact with a galvanic cell, which generates a current proportional to the oxygen content of the water. The apparatus used is first calibrated with water containing known amounts of oxygen.  An inlet 19 for the water under test is sealed into a chamber 18, connected through a vertical tube 20 to the base of a chamber 1 from which the water flows away through a device 22 for maintaining a constant head.  Within the chamber 1 is mounted a galvanic battery, the cathode 7 of which is sensitive to oxygen, generating a current measured between the electrodes 9, 11.  The top of the chamber 1 is connected to a generator for hydrogen 23, and to a vessel 14 containing palladium-aluminium catalyst, mounted above the water inlet chamber 18.  In operation, the apparatus is filled with hydrogen, bubbles of which are drawn into tube 20 by the downward flow of water, and absorb at least some of the oxygen contained in the water.  The water is discharged through the constant level overflow 22, and the mixed gases flow around the galvanic cell and pass into the catalytic chamber 14 where any oxygen combines with hydrogen by silent burning, leaving oxygen-free hydrogen for re-cycling.  The loss of hydrogen gas draws up acid from the bottom of the tube 24 to contact an electrode 27 which with electrode 28 is connected to a battery generating hydrogen.  When the hydrogen is replaced, the back pressure forces the acid below the electrode 27. Any excess pressure is vented through the valve 31.  The galvanic cell is of the type described in Specification 707,323, and in the preferred form consists of silver wire cathode, an anode of finely-divided cadmium and dilute potassium hydroxide.

Title: Electrically controlled amusement machine
IPC: G07F17/38
Filed: 1963-06-20
Abstract: 967,345. Coin-freed amusement apparatus. A. J. L. CROMPTON. June 20, 1963, No. 24563/63. Heading G4V. [Also in Division A6] An automatic amusement machine having a plurality of play-stations 16 has a master controller which operates cyclically to first indicate to a player when to insert a coin at one of the pay-stations and then, after projecting a ball 28 to the top of an upright or inclined panel 12 and making a random selector mechanism operative to illuminate divisions 33 successively, actuate a coin dispenser provided that the ball drops through a receptacle 42 corresponding to the pay-station previously primed by the insertion of a coin. Any number of players can take part in a game. The master controller may consist of a drum which is rotated at a low speed by a motor so that raised portions on the drum actuate electrical contacts in sequence as the drum rotates. When the controller causes "play" lights 18 to be illuminated, one or more players may insert their coins into slots 17 in the pay-stations of their choice and thereby close priming contacts. After a period of time, the controller extinguishes the "play" lights and causes any further coins inserted to be rejected and returned to the players. The'controller then activates the solenoid 51 of the projector 29 so as to project the ball 28 from a cup 48 and cause it to fall between deflecting pegs and finally pass over a hinged member 42 to depress a striker-pin 44 to close contacts of a secondary priming device while the random selector, which is of the kind described in Specification 881, 803, is rotated to illuminate successively the divisions 33 and stop opposite a division at random to indicate the odds. The odds are only paid out when the contacts of the secondary priming device are in the same electrical circuit as the contacts of the priming device operated by a coin. Both the coin freed priming devices and coin dispensers may be of the kind described in Specification 967, 344.

Abstract: 1516675 Controlling light MULLARD Ltd 9 June 1975 24622/75 Heading G2F The birefringence #n of a plate of ferro-electric ceramic material having a sub-grain domain structure, and as measured in the presence of a fixed electric field, is increased by reducing the plate thickness t microns to a value not exceeding twice the average grain diameter G of the material, and preferably between G and ¢G. Fig. 2 shows the curve relating to orthorhombic 8/65/35 lead zirconate/titarate (PLZT), for which G and hence t are very small. Such a plate is made by securing a thicker plate to a substrate and polishing it with special techniques. Other materials with greater G may also be so treated or may undergo conventional polishing, e.g. rhombohedral 7.5/72/28 PLZT, where G # 40 Á. In either case interdigited electrode combs are then deposited on one plate surface. It is stated that the curve of Fig. 2 is due to the partial cancellation between the polarisations of different domains, and if appropriate, different grains, at greater thickness t, Fig. 3 (not shown).
