Title: Improvements in control mechanism for bi-fuel carburetting systems
IPC: F02M1/00
Filed: 1922-10-21
Abstract: 209,515. Dodson, E. Oct. 21, 1922. Spray carburettors. -The hand-actuated throttle valve B<4> of a carburettor using a fuel having a low self-ignition temperature, e.g. petrol, is connected by a linkwork with the throttle valve A<5> of a carburettor using a fuel having anti-detonation properties, or a high self-ignition temperature, e.g. alcohol, in such a manner that the latter valve commences to open at an adjustable partial opening of the former and the two are fully opened simultaneously. The connecting linkwork comprises two throttle levers B<5>, A<3> which are connected by a lost-motion link C having a nut C<4> which abuts against a boss A<4> through which the link C slides, a spring D tending to keep the valve A<5> closed. The pivoted end C<2> of the link C is adjustable on the curved part of the lever E<5> which is circular with respect to the boss A<4> in the position shown. A further adjustment may be provided as shown in Fig. 2, in which the lever B' is replaced by a lever E which is mounted on a floating pivot E<2>. attached to a radius rod F, and operates the petrol throttle through a link G. The floating pivot is moved by an altitude control arm L, connected to a hand lever or a barometric capsule, until the throttle-valve A<5> is closed; a slot L<2> enables further movement of the arm L, to close an independent petrol-mixture throttle valve. Separate barometrically or handactuated valves, situated in the passages leading from the carburettors, or a three-way cock at the junction of the passages and' having a bypass for the petrol mixture for slow-running, may be used. The two fuel-mixtures may, however, be kept separate and only mix when they reach the cylinder.

Abstract: 1,192,477. Metallized fabrics. LA CELLOPHANE. 17 June, 1968 [8 Aug., 1967], No. 28785/68. Heading B5N. Metallized fabrics are produced by depositing a layer of a non-adherent varnish on a smooth flexible sheet of a temporary support, depositing under vacuum a layer of metal, e.g. aluminium, on the varnish, coating a layer of adhesive of neutral pH on the metal layer, drying the adhesive, bringing the coated face of the temporary support into contact with the fabric and applying heat and pressure to the resulting assembly so that the metal coating is adhered to the fabric, and stripping off the support to leave the metal and varnish layers adhered to the fabric. The fabric may be woven, tricot or non-woven fabric or felt made from cellulose acetate or nylon and the temporary support may be a film of regenerated cellulose, cellulose acetate or butyrate, polyvinyl chloride, a polyester, a polyamide or rubber or paper impregnated with plastic material. The varnish may be a cross-linkable acrylic compound derivative dissolved in an organic solvent, e.g. methyl isobutylketone or methyl ethyl ketone to which ethyl acetate is added and may also contain dyes or pigments. The adhesive, which may be an aqueous emulsion of an acrylic or vinyl compound or copolymer thereof, e.g. an emulsion containing a copolymer of acrylonitrile and vinyl chloride and/or vinyl acetate, or an elastomer is adjusted to a neutral pH by for example the addition of ammonia or acetic acid and may also contain zinc oxide or titanium dioxide. The support bearing successive layers of varnish, metal and dried adhesive may be reeled up and kept for later application to the fabric or passed directly to a machine where it is applied to the fabric with heat and pressure, e.g. using a calender machine heated to 90-100‹ C. or in a press the plates of which are heated to 120‹ C. The assembly may then be cooled by passage over a cooling cylinder and the support stripped off. Patterned effects may be produced by applying the adhesive locally in areas to form a decorative pattern.

Title: Improvements in starting switches for alternating current motors
IPC: H02P1/26
Filed: 1922-10-25
Abstract: 198,614. Wheeler, S. S. Oct. 25, 1922. Alternating-current motor starters.-A starter for alternating current motors comprises a contact member in the form of a flat board 22 movable on hinges 12, 13, operated by a handle 105, and carrying segmental contacts 27 - - 31, which are attached to flexible leads and wipe over two groups of stationary contacts' 56 - - 59 and 70, 74, 75. One group of contacts is connected to auto-transformers, the other groups, in the example shown, to three-phase motor starter terminal leads 66, 67, 73. Intermediate tappings of the transformers are connected to two of the motor leads. Starting from the lowest position of the member 22. Fig. 2, the first movement of the handle connects the transformers across the mains 15, 16, 19, Fig. 5, and the motor windings across portions of the transformers. The motor starts on reduced voltage, and the operator holds the starting handle stationary until a visual indicator 78 operated electromagnetically by a series coil 21 shows that the current strength is below a permissible limit. Further movement of the starting handle first disconnects one end of each transformer, leaving portions in action as impedance coils between the motor windings and the mains, next short circuits the impedance coils, and finally disconnects the remaining terminals of the transformers and connects the motor windings directly to the mains. A holding- on magnet 112 retains the switch in the full running position against a retracting-spring. The magnet may be short circuited by overload relays 100, 101 arranged in shunt to iron strips 98, 99, the resistance of which, owing to heating, increases with a sustained current. The contact members and terminals are mounted on a slate slab 11 and all the parts except the handle are enclosed in a casing 55 having a door 90 and a window for viewing the indicator 78. The contact-carrying board 22 can readily be removed from its hinges. Modifications for a two-phase motor are described.

Abstract: 1431384 Control of turbines GENERAL ELECTRIC CO 20 June 1973 [21 June 1972] 29290/73 Heading G3N [Also in Division H3] In a turbine control circuit receiving a load reference signal, at point 11, also controlling a steam flow control valve for the turbine, the control is such that, upon setback of the load reference signal being required, contacts 27, 30, 38 change state ensuring that the reference signal decreases, at an adjustable rate set by potentiometer 29, to a pre-set level set by potentiometer 37. As shown, normally, biases 25, 26; 35 keep operational amplifiers 23; 33 in integrator 17; limiter 18; resp. negatively, resp. positively saturated, the latter state keeping bias diode 15, via current amplifier 16 cut-off, capacitor 22 being charged to a value corresponding to the voltage level at point A, and following its variations closely. Upon closure of contacts 38 and 30, and opening of contact 27, the voltage level on the anode of diode 34 decreases, allowing diode 15 to conduct, to place capacitor 22 in a feedback circuit of integrator 17, the capacitor discharging via resistor 31 and potentiometer 29 to define the load reference linear, decrease rate. The decreasing voltage at A is fed back to amplifier 33, so that due to rise in its output, eventually the decreasing voltage at the cathode of 24 is clamped by the latter rise, clamping the reference voltage at a value set on the potentiometer 37. Chain 13, 14 biases diode 12. Several inputs may be connected to point 11, that which has the lowest value exerting the overriding control. In the control of a steam turbine the load reference signal causes, via a steam control valve, reduction of the steam flow at a given rate to a given level, to compensate, for example, for loss of steam.
