Title: Improvements in or relating to braking systems for alternating-current motors
Inventor: STEELE RICHARD BENNINGTON
IPC: H02P3/24
Filed: 1955-01-03
Abstract: 764,511. Control of A.C. motors. AIR REDUCTION CO., Inc. Jan. 3, 1955, No 125/55. Class 38(3) In a control system for a series commutator motor, closure of a switch 19 energizes the operating coil of a relay to open contacts 22, 23, and close contacts 24, 25. The armature 13 and field winding 14 are thus connected in a series between supplylines 11, 12, the vibrating contacts 16 of a centrifugal governor being included ir. the motor circuit. A shunt resistor 17 allows the passage of limited motor current when the contacts 16 are open, and capacitor 18 reduces arcing. When the switch 19 is opened to stop the motor, the armature and field windings are connected in a closed circuit through contacts 22, 23, so that the motor now acts as a self-excited direct-current generator to provide rapid braking action. At the instant at which the switch 19 is opened, a lamp 40, acting as a low impedance, allows a substantial current-surge to pass through the motor circuit so that generator action is initiated when the field winding 14 is excited from the first half-cycle of the current passing through the lamp 40. The filament of the lamp quickly becomes hot so that its resistance increases and' the motor is then substantially isolated from the alternating- current supply. In another arrangement, the function of the lamp 40 is performed by a time-delay relay which completely isolates the motor from the supply after allowing a current-pulse of short duration to pass to the field winding 14 for initiating direct-current. generator action, Fig. 2 (not shown).

Title: Lens for radio waves
IPC: H01Q15/02
Filed: 1947-01-02
Abstract: 650,767. Directive radio systems. WESTERN ELECTRIC CO., Inc. Jan. 2, 1947, No. 161. Convention date, Jan. 22, 1946. [Class 40 (vii)] A lens for use with an aerial radiating or receiving electromagnetic energy comprises one or more dielectric channels, i.e. a pair of spaced parallel conductive plates, with at least one surface of the lens, formed from the edges of the plates, of lenticular form. Fig. 2 shows a lens comprising a single dielectric channel with the surface facing the source 19 elliptically concave. Owing to the increased phasevelocity in the channel, the lens is positive whereby a spherical wavefront radiated from 19 is converted to a plane wavefront. The lens may be used with the source off-set from its axis, whereby energy reflected from the surfaces of the lens does not produce interference effects at the source while the directive properties of the lens are impaired only very slightly. Fig. 5 illustrates a biconcave lens comprising a plurality of identical dielectric channels filled with polystyrene foam. The surfaces of the lens are accordingly of cylindrically concave form so that a horizontal fan-shaped beam is obtained from a point source. The radiator used comprises a sectoral horn, shown in plan in Fig. 7, which produces a vertical fan-shaped beam so that the combined system provides a beam which is narrow in both the horizontal and vertical planes. Fig. 8 (not shown), illustrates a piano-ellipsoidal lens producing substantially equal directivity in both the vertical and horizontal planes ; such a lens may form part of either a linear or conical scanning system, the primary element being so moved relative to the lens as to produce the desired scanning effect. Fig. 14 shows a front view of a lens comprising a plurality of separate zones and Fig. 15 shows a side view of plate 68 of Fig. 14. The zones 90, 91, 92, 93, 94 of the lens are stepped so that the ray paths through adjacent zones to a plane parallel to the surface remote from the source 19 differ by a wavelength. As a result of the stepping the band-width of the lens is increased above that of the corresponding unstepped lens, also shown in Fig. 15. In Fig. 21, the lens of Fig. 13 is shown fitted into the aperture of a horn having equal horizontal and vertical flare angles. The lens may be tilted with respect to the axis of the horn to prevent interference through reflection being produced at the throat of the horn. The lens may be used as a support for a dielectric cover to protect the lens and horn against the weather. Fig. 24 illustrates a repeater system comprising two aerial systems of the type illustrated in Fig. 21 arranged back-to-back and coupled by a repeater 144.

Abstract: 468,690. Folding cartons, display stands, &c. ACME SHOWCARD & SIGN CO., Ltd., and LINDSEY, G. Jan. 4, 1936, No. 385. [Class 18] [Also in Group XVIII] A folding carton, display stand, &c. is made at least to some extent self-erecting by providing, e.g. in the trapezoidal display stand shown in section in Fig. 1 (which may also be used as a container) an elastic thread 18 between the end walls 16, 17. In this model a support 9 with its sides 10 upturned and secured to the top 7, underlies openings 8 within which the lower ends of the goods to be displayed are held. The device folds by hinging the ends about their junction with the top, one long side having a longitudinal crease which permits it to fold beneath the top. It is held in the folded position by a band or strip. The bottom may be omitted and the two long sides connected by a spring. The display stand shown in Fig. 4, comprises a trapezoidal box secured to a backing sheet 21, which may carry advertising matter. The device shown in Fig. 6, serves also as a container, flaps 24, 26 keeping the container extended and flap 25 serving as a lid. An extension 27 from flap 26 is secured to the lid 25 and an elastic thread 18 is secured to an extension 28 and serves to close the lid and the flap 26.

Title: Improvements in or relating to electronic time delay relays

Abstract: 791,305. Relay devices. ELESTA, Ltd. Jan. 5, 1956 [June 20, 1955], No. 446/56. Class 40 (3). In a time-delay relay device in which a relay 9 is operated to close contacts 11 in an external utilization circuit 12 by the firing of a cold cathode tube 5 the discharge of the latter is initiated by a trigger electrode 8, the firing voltage of which is derived from the voltage across a condenser 13 and the rate at which the latter charges when switch 4 is closed is determined by the leakage current produced by the ionizing effect of a radioactive source 17 on the gap between two electrodes 15, 16 connected in series with the charging circuit of the condenser. The source 17 consists, preferably, of a preparation containing plutonium, radium or actinium and the extent of the ionization and consequently the time required for the voltage across condenser 13 to reach the firing potential of the trigger electrode 8 may be varied by varying the distance between the source and the plates 15, 16 by rotation of arm 18 (carrying the source 17) about spindle 19 or, as described with reference to Fig. 2 (not shown), by employing a fixed radioactive source between which and the plates 15, 16, an adjustable screen is positioned. In this manner the delay between closing switch 4 and the operation of relay 9 may be varied from a few seconds to over twenty-four hours. When the relay operates the condenser is discharged through a low resistance 14 by means of a further set of contacts 10.

Abstract: 1,178,381. Measuring currents and voltages. HAWKER SIDDELEY DYNAMICS Ltd. Jan.5, 1967 [Jan. 5, 1966], No.520/66. Heading G1U. To reduce the effect of capacitive leakage current across the open contacts of switches 11 Fig. 2 in the unused channels of a number of channels connected in parallel to the input of a common amplifier 13, a second switch 18 is included in each channel and this switch, when "open", connects the portions 21 of the channel conductors between the switches to a guard rail 16 of the amplifier which in turn is connected through the switch 14 in the one channel being used to an earthed terminal of the signal source. A guard rail 20 for the conductors 21 between the switches is connected to the amplifier guard 16, and in a modification where the main switch 11 is arranged to transfer the input signal to an alternative line through contacts 85, Fig. 5, should the switch 18 operate before switch 11, the rate of discharge of a capacitor 22 connected across the input channel which is thereby short circuited is reduced by a resistor 26 connected between the contacts 19 of the switch 18. Alternatively the short circuiting of the capacitor is prevented by placing the switches 18 on the input side of the main switches 11 and reversing the connection of switches 18 so that their movable contacts are connected to the inputs of the main switches as depicted in Fig.4 (not shown). When semiconductors are employed as switching elements, the leakage conductance is also reduced by the circuit described.
