Abstract: 870,738. Automatic control systems for alternators. ROSS Ltd. Oct. 6, 1959 [Oct. 17, 1958], No. 33295/58. Class 38 (4). [Also in Group XXXV] Apparatus for measuring the rotor angle of a power alternator whose output is connected to those of plural further alternators of a grid system (i.e. the angle between an instantaneous datum position of the alternator shaft at zero power input or output and the datum position when power is being either generated or absorbed from the system) wherein an auxiliary three-phase alternator is driven mechanically from the power alternator to energize the stator (or rotor) of a torque differential receiver whose rotor (or stator) is energized from the combined outputs of the further alternators; an indicator being connected to the rotor shaft of the receiver to display the prevailing rotor angle within a range of 360 degrees and to indicate by rotation any variation of rotor angle beyond such range arising from pole slipping of the power alternator. In Fig. 1, a permanent magnet a is rotated by the shaft of a 3-phase power alternator (not shown) within γ-connected stator coils c, d, e energizing γ-connected stator coils g, h, i of a torque differential receiver having similarly connected rotor coils i, j, k transformer energized from an integrated 3-phase grid supply system to which the power alternator is connected, and mounted on shaft m operating pointer n over angular scale o. The alternator is initially run up to speed, connected to the grid, and the pointer is zeroized by moving shaft b relatively to the magnet a or rotating the stator of the torque differential receiver. Steam is then supplied to the alternator turbine, and the angular rotation of its shaft is advanced relatively to that of the 3-phase grid supply current as power is fed into the latter; such rotation being indicated by pointer n; pole slipping being indicated by continuous pointer rotation in synchronism with the slip. A cam r on shaft m operates contacts on a rotatable carriage (not shown) to operate servomechanism controlling alternator excitation or turbine steam supply at a predetermined angle of advance. Other contacts may operate warning devices and a repeater may display the deflection of pointer n at a distance. The rotation of pointer shaft m may be linked to a pen recorder (Fig. 2, not shown).

The device shown is of optical type and comprises an impulse disc 11 which can be turned by a knob 40 and has apertures 28 to allow light from a source 27 to reach a sensor 29. The wheel also has teeth 30 co-operating with a detent spring 31. The electrical pulses from sensor 29 are passed through a shaper 16 and a changeover switch 17. The latter determines whether the indicator is driven forwards or backwards and is controlled by signals from contacts 19a, b one or the other of which is engaged by a contact arm frictionally coupled to the shaft 10 of the impulse wheel. Other embodiments are described using a Piezoelectric or electromagnetic effect, Figs.1 and 2 (not shown), or acting as rotary interrupter switches - see Division H1.

Abstract: 747,648. Controllers; electrically released switches. SCOTTISH MECHANICAL LIGHT INDUSTRIES, Ltd. Dec. 31, 1954 [Dec. 4, 1953], No. 33747/53. Classes 38(3) and 38(5) Relates to automatic means for preventing an electric motor driving a disintegrator from running idly when the supply of grain to the disintegrator is exhausted or is stopped by clogging. To start the motor, a double-pole switch 1 is closed to shortcircuit an ammeter 2. A single-pole switch 3 is also closed so that actuation of a pushbutton 5 energizes a contactor 4 which connects the motor 10 to its supply and closes a self-holding contact 6. Before disintegration is commenced, the switch 1 is opened to connect in circuit the ammeter 2 which is used for checking the load whilst the feed-rate is adjusted. For automatic operation, a mercury switch 8 is closed 'by pressing button 7 and is held closed by coil 9 as long as the motor current exceeds a predetermined value, the switch 3 being opened to remove a shortcircuit from the mercury switch. When the motor current passing through the coil 9 drops below the pre-determined value, the mercury switch 8 opens to de-energize the contactor 4 and disconnect the motor. The driving motor may be of the singlephase or three-phase types.

Abstract: 1428997 Developing process FUJI PHOTO FILM CO Ltd 16 July 1973 [15 July 1972] 33826/73 Heading G2H An electrostatic latent image formed on a photo-conductive surface of a sheet or web material is developed by applying thereto a liquid developer comprising as toner a graft copolymer of a pigment and one or more polymerizable monomers, the toner being dispersed in an electrically insulating carrier liquid, and the liquid developer being applied to said surface by means of a roller having a porous liquid-absorbent and resilient outer layer which is impregnated with the liquid developer. Many suitable monomers are listed and include "dispersion monomers" that facilitate the dispersion of the resulting toner in the carrier liquid, and "polar monomers" which serve to impart charges to the resultant toner. In one example, carbon black is graft copolymerized with lauryl methacrylate (as dispersion monomer) and diacetone acrylamide (as a positive charge control polar monomer) and the resultant toner material dispersed in kerosene. In other examples the diacetone acrylamide is replaced by one of the following polar monomers:- methoxymethylacrylamide, butoxymethylacrylamide, N-methylacrylamide, morpholinoacrylamide, acyloyl morpholine, γ-trimethoxysilane-n-propylmethacrylate, γ-trimethoxysilane, ethylhexyl acrylate, vinyltrimethoxysilane, vinyltriphenoxysilane, vinyl-tri-#-(methoxyethoxy) silane, acrylamide, acrylic acid and acrylonitrile. In a further example there is added to the liquid obtained in the first example about 0À01% of a half-alkyl (C 12 ) amide of a diisobutylene/maleic anhydride copolymer as a charge control agent. The developer applicator may comprise a layer of foamed polyurethane, foamed polyethylene or foamed natural rubber on a rigid core. The invention is particularly applicable to the development of latent images on photo-conductive coated iron sheets. A number of suitable apparatuses are disclosed which are generally similar to those disclosed in Specification 1417777.
