Title: Circuit arrangement for an electronic subscriber feeding system
IPC: H04M19/00
Filed: 1977-12-01
Abstract: The circuit arrangement for an electronic subscriber feed with loop current monitoring, ringing tone connection and hybrid arrangement for the transfer from two-wire to four-wire operation with current generators disposed in a balanced relationship with one another uses operational amplifiers (J1, J2) purely as isolation amplifiers for the current generators. The modulation of the loop current is controlled via the inverted inputs of the operational amplifiers (J1, J2) in such a way that, when the amplification is increased in the modulation arrangement, the dynamic self-balancing of the current generators is increased. When the subscriber loop is open, a differential amplifier (J3) is controlled to achieve a high hybrid loss in such a way that no AC voltage reaches the output (G) on the four-wire side. <IMAGE>

Abstract: 1,191,078. Control of D.C. motors. ROBERTS MACHINE REBUILDERS Inc. 25 Oct., 1968 [6 June, 1968], No. 50761/68. Heading H2J. [Also in Division G3] Signals representing back e.m.f. across and current through the armature of a motor are derived and used to energize control windings of a magnetic amplifier used to control the energization of the motor armature. The motor field is separately energized (Fig. 1a, not shown). The armature is energized by a bridge rectifier comprising two S.C.R's 24, 26 and two diodes 28, 30. The triggering of the S.C.R's is individually controlled by two primary windings 44, 56 of the magnetic amplifier. The back e.m.f. is applied through filter 40, 42 to control the energization of a first control winding 132. A second control winding 124 is controlled by a set-speed control 126; since both windings 124, 132 are energized through a resistor 117 their energization is interdependent. The armature current responsive signal is derived across an inductance 38 in series with the motor and applied to a third control winding 110 which forms the emitter load of a transistor 100 coupled to a further transistor 120 across the control 126 so that the energization of windings 124, 132 also depends on that of winding 110.

Title: Improvements in or relating to Aircraft Control Systems.
Inventor: HOWARD RONALD WALTER
IPC: G05D1/02
Filed: 1966-11-17
Abstract: 1,182,268. Automatic control of aircraft. ELLIOTT BROS. (LONDON) Ltd. Nov.14, 1967 [Nov.17, 1966], No.51528/66. Heading G3R. In a system for aligning the track of an aircraft with a runway during automatic landing, a signal corresponding to rate of yaw of the aircraft is applied to an integrator which is normally slaved so that its output corresponds to the error between aircraft heading and runway heading, but which varies only with yaw rate during the final landing phase. In Fig.1, signals from a rate of turn gyro 1 on an aircraft are applied to an integrator 3 the output of which thus varies with changes of heading of the aircraft and is applied to a control circuit 33. Signals 25, corresponding to the measured aircraft heading, are compared with signals 27, corresponding to the heading of a runway selected for landing, so that any difference 13 corresponds to the relative heading. When the aircraft descends to say 800' during landing, switches 9 close and the output of integrator 3 is maintained in correspondence with this relative heading by applying any difference from a comparison amplifier 15 through an amplifier 19 and an integrator 17 to modify the input to integrator 3. Then, when a lower altitude of say 150' is reached, switches 9 open so that integrator 3 operates without correction to compute the relative heading until, at a still lower altitude of say 20', circuit 33 is connected to control the ailerons and rudder (not shown) so that the relative heading is reduced to zero and the aircraft is aligned with the runway just prior to touchdown. The system is duplicated so that alarms are operated and/or automatic changeover effected in the event of discrepancies between the two systems due to faults. For this purpose comparators 35, 41 and 31 compare corresponding signals in the two systems and signals from a second integrator 29 with those from integrator 3. A bias voltage applied at 21 assists in ensuring such fault detection. Gyro 1 also operates an alarm at 7 in the event of malfunction. In a modification, the inputs to the integrators from gyro 1 are maintained at zero by feedback through further integrators until a low altitude is reached.

Title: Heat sealer apparatus
IPC: B65H45/22
Filed: 1976-12-16
Abstract: The heat-sealing unit has a plurality of elongated heating elements (11) which are arranged parallel at a distance from one another on a convexly curved carrier (12). Said heating elements form a slideway for a continuous set of business forms consisting of at least two layers (14, 15) and serve for the localised heating of hot-melt adhesive arranged between the layers. Downstream of the heating elements there is arranged a pressing device (24, 25) which brings the heated layers into intimate contact with one another. By means of the direct contact between the set of forms and the heating elements and the localised heating, the heating energy can be kept small, it being possible at the same time to prevent overheating of the set of forms. <IMAGE>
