Abstract: 464,443. Aerials; wireless signalling. BLUMLEIN, A. D., CORK, E. C., and PAWSEY, J. L. Oct. 19, 1935, Nos. 28907/35 and 19178/36. [Class 40 (v)] A short-wave system in which the aerial is coupled to the transmitter through a feedline which is electrically long with respect to the highest modulation frequency is characterized by the provision of correcting circuits inserted at or near the aerial whereby the effective impedance over a range of frequencies is a substantially - constant resistance equal to the resistance of the aerial at resonance. In Fig. 2, (Comp.) a dipole aerial is represented by the parallel impedances R, C, L, and the correcting circuit consists of a capacity C2 in series with an inductance L2, both preferably shunted by a resistance r. The correcting circuit is inserted in series between one end of the aerial and the tubular feed-line L ; or it may be tapped to the aerial inductance ; or, if the aerial is fed at its centre, the correcting circuit may be inserted between the feeder and earth. As shown in Fig. 5 (Comp.) the correcting circuit L5, C5, r is connected across the centre feed-line G and earth a quarter wave-length, away from the aerial. As shown in Fig. 2 (Prov.) the fieldline 3, 4 is terminated by an outer sheath 7, surrounding the tubular conductors 3, 4 and connected to the latter at a point 8 a quarterwave away from the aerial 5, 6 and to the aerial through a resistance R2. In Fig. 4 (Prov.) two parallel sheaths 11, 12 are used as correcting terminations, and also serve as interference-suppressors of the kind described in Specification 438,506.

The front and rear stringers 29, 28 on each side of the section 11 are spaced apart to form a longtitudinal slot 41 Fig. 5 engaged by rollers 38, 39 on a runner 37 pivotally and adjustably mounted in one of a series of holes 40 on a bracket 47 secured to the top face of the trap door 15 Fig. 2. A similar arrangement slidably secures the ladder section 11 to brackets 12 secured to the loft floor 13 adjacent the opening. Radius arms 17 are pivotally secured near the top of the section 11 and to brackets 18 on the loft floor to control angular movement of the ladder during lowering, torsion springs 20 Fig. 6 (not shown) fitted around pivot pins 19 on the brackets 18 serving to oppose the lowering movement of the ladder. Adjustable stops 43 Fig. 2 on the section 11 limit its downward movement by abutting against the brackets 12 and a similar arrangement ensures that the ladder section 10 is extended to a position to bring the treads of the overlapping steps level. The stringers which may be extruded, rolled or drawn sections of light aluminium alloy, are secured to the front and rear flanges 23, 24, Fig. 4 of grooved or corrugated channel section steps 21., Instead of the unitary stringer member 29, two similar overlapping L-section members may be secured together to form the stringer. According to the first Provisional Specification instead of the rollers 38, 39, Fig. 5, the slots 41 are engaged by brass sliders pivoted on bracket pins provided with adjustable spring controlled friction washers for resisting motion of the ladder relatively to the pins.

Abstract: 308,158. Lehr, A. Oct. 12, 1928. Buoyant furniture. -Relates to benches or seats having in- -ternal pivotally arranged floats which are turned transversely to the bench when afloat to give additional stability. According to the invention the floats d<1> are arranged to occupy the transverse position automatically on the bench a being set afloat. The floats are locked in both positions but are pressed by a coil-spring disposed around the pivot towards the transverse position. On reaching the water the floats are raised on their spindles ;relative to the bench and are released to turn thereon under the action of the springs. Should the bench capsize before reaching the water the necessary relative movement takes place gravitationally. Radial lugs limit the rotary movement of the floats, which are locked in the operative position by spring- pressed pawls engaging ratchet teeth on discs secured to the spindles thereof. The rotary movement of the floats relative to the bench may be occasioned by screw-threads on the spindles.

IPC: G05F1/59
Filed: 1959-08-28
Abstract: 946,212. Automatic voltage control systems. GENERAL ELECTRIC CO. Ltd., and J. W. McPHERSON. Aug. 18, 1960 [Aug. 28, 1959; Oct. 29, 1959; Feb. 26, 1960], Nos. 29539/59, 36818/59 and 6915/60. Heading G3R. [Also in Division H3] A circuit for providing a variable impedance between two terminals 3 and 4 more particularly for use in a stabilized power unit comprises two parallel branches, the first comprising a transistor 1 or a corresponding valve and a resistive impedance 6 and the second comprising a resistor 7 and a transistor 8 or a corresponding valve, the junction of 5 and 6 being connected to the input electrode of 8 and a control voltage being applied to the input electrode of 5 and the resistors being chosen so that the maximum power which can be dissipated in the circuit is more than twice the maximum which may be dissipated in either transistor. The circuit shown is such that when the maximum current is flowing and it is desired that the circuit shall drop a voltage approaching the maximum permitted by the dissipation limit of transistor 5, the voltage applied to the base of transistor 8 is such that it bottoms and the circuit essentially comprises transistor 5 in parallel with a resistor 7. Under these conditions it is arranged that the resistance of the two arms 1, 2 of the circuit are equal and to this end an additional diode similar to diode 10 may be included in the collector circuit of transistor 8. When the current flow is appreciably less than the maximum, transistor 8 becomes high impedance and the voltage drop is controlled by transistor 5. The diode 6 is used in place of a linear resistor so as to limit the voltage dropped thereacross. The control range of the circuit may be extended by adding transistors in parallel with 5 and 8 (Fig. 4, not shown). An alternative circuit using the valves (Fig. 5, not shown) has a Zener diode connected in each cathode circuit. Fig. 7 shows an automatic voltage control arrangement in which control is effected by the circuit 1, 2 previously described. The control voltage is derived from a comparator 33, 34 in which a proportion of the output voltage from 23 provided by a potentiometer 31 is compared with a reference voltage developed across a Zener diode 28 and the output from the comparators is applied through an amplifier 41 to the control circuit 1, 2. A Zener diode 39 is connected in a higher voltage supply for the collector of transistor 33.
