Abstract: 1,234,354. Electro-medical apparatus. HUMETRICS CORP. Oct. 6, 1969, No.48913/69. Heading G1N. In apparatus for indicating the heart sound sequence, electro-cardiac voltages are applied to the apparatus, the "R" waves triggering a circuit to produce respective outputs each of which is applied to a circuit which initiates a plurality of pulses synchronized with the temporal sequence of heart sound of the cardiac cycle, the sequence being indicated visually. As shown, electro-cardiac voltages are applied to an indicator 10, via electrodes 14, 16 attached to a human chest, an electrode 18 acting as a reference for the electro-cardiac voltages. The electro-cardiac voltages are applied over lines 32, 34 to a differential pre-amplifier 38 to produce an electro-cardiac voltage which is then amplified and passed to a threshold circuit such that only the R waves are shaped and passed to a Schmitt trigger circuit 74. Each of the resultant square output pulses of the circuit 74 is differentiated and applied simultaneously to two monostable multivibrators 84, 86. Multi-vibrator 84 is thus rendered conductive to energize a lamp 22 for a fixed duration (determined by a capacitor 101) co-extensive with the occurrence of the "first heart sound". Multi-vibrator 86 is also rendered conductive for a duration longer than that of multivibrator 84 (determined by a capacitor 110 and a control voltage, representative of heart rate, from an averaging network including resistors 176, 178 and capacitor 182, and transistors 190, 192). A lamp 24 is only energized when the multi-vibrator 84 reverts to its stable, non-conducting state, and the multi-vibrator 86 is in its conducting state, thus indicating the systolic interval. When multivibrator 86 reverts to its stable, non-conducting state, the trailing edge of its output pulse is differentiated (by capacitor 128 and resistor 130) and the resulting positive voltage spike is applied simultaneously to trigger multi-vibrators 88, 90 into their unstable, conducting state. Lamp 26 is energized during the unstable state of multivibrator 88 (determined by capacitor 142) coextensive with the occurrence of "the second heart sound". The time duration of multi-vibrator 90 is longer than that of multi-vibrator 88 and is determined by a capacitor 158 and the control voltage, representative of heart rate, from the averaging network. A lamp 28 is energized when the multi-vibrator 88 reverts to its stable state and for the duration of the unstable state of multivibrator 90 until a following R wave triggers the circuit, thus indicating the diastolic interval. Thus, a doctor may listen to the heart sound with a stethoscope whilst watching the lamps to thus correlate heart sound so as to determine any murmers in the heart. Heart rates below a predetermined magnitude may be compensated for by a transistor 198. Temperature variations are compensated for by a transistor 204 and diode 206. The circuitry is energized by a rechargeable battery 208, provided in a unit 12.

Abstract: 1,250,070. Semi-conductor devices. ITT INDUSTRIES Inc. 18 Sept., 1969 [25 Sept., 1968], No. 46056/69. Heading H1K. Leakage channels in the base region of a planar transistor are interrupted by an annular zone of the opposite conductivity type which surrounds the emitter region at a distance greater than the depletion layer thickness when it is biased by a blocking potential lower than the breakdown voltage of its associated junction. As shown, Figs. 3 and 4, an NPN planar transistor is provided with a P-type annular channel stopper region 7 at the surface of the base region 5 surrounding the emitter region 3. Region 7 is biased by means of three small transistor structures formed in the common N type collector region and their emitter-base junctions 10a, 10b, 10c are connected in series between the collector region and the annular region 7 so that they are reverse biased and form a potential divider. The device may be constructed in an N-type epitaxial layer on a P-type substrate and may form part of an integrated circuit employing diffused isolating regions 13. The base region 5 of the main transistor is contacted at region 11 which may be highly doped. Other methods of biasing the annular region are described with reference to Figs. 6 and 7 (not shown), in which a further base-collector junction is connected in series between the collector and the annular region, and Fig. 8 (not shown), in which the annular region is connected to a zone in an electrically isolated part of the I.C. A temperature compensated Zener diode, Fig. 10 (not shown), is simulated by a series connection of the base-emitter junctions of transistor structures. Three of the transistors are provided with annular channel stopper regions in their base regions. In one of these transistors the annular region is biased by strapping it to the collector region and in the other two transistors the annular regions are connected together and to the base of a further transistor structure, the emitter junction of which is connected to a suitable point of the series junction chain.

Abstract: 1,267,040. Aircraft ejector seats. J. R. COYLE. 29 July, 1969 [19 Feb., 1969], No. 38085/69. Heading B7G. [Also in Divisions E2 and H2] An airman's ejector-seat buckle 2, 3, 2a, 3a, is released, and his flotation vest inflated, or a generator is started, when a switch 14 associated with the seat is immersed in water, a battery 15 supplying the energy when lanyard 12 is pulled. The buckle comprises a male part 27 engaging in recess 26 and held there by a sliding bolt 29 in the female member 3. The latch bolt 29 slides in cavity 32 and has an upper lip 35 which retains the male part in a vertical direction and is itself held in the cavity by a cover-plate 41. The bolt is loaded by springs 43. A keeper key 105, sliding on a pin, serves to prevent inadvertent release of the buckle due to strain. The latch-bolt may be retracted by manual means 30 or automatically on immersion. Manual release 30 is provided by finger-plates 50, 60 sliding transversely oppositely on pins 52, 62 against springs 81. These have downwardly projecting arms 51, 61 having bottom pins 96a, 96b and mutually interengaging notches 53, 63 which prevent release by movement of one only. Mutual transverse movement of these plates enables pins 71a, 71b on the arms 51, 61 to move axially into axial slot 71, thus allowing axial movement of the plates which in turn withdraws the latch-bolt 29. To provide automatic release, a cam-plate 90 has angled cam-surfaces 95, 96 to engage the pins 95a, 96a on the sliding plates to slide them towards each other and so release the bolt. The necessary movement of this cam-plate is provided by explosives 103, Fig. 6, ignited electrically when immersion takes place. The firing charge is derived from a charged condenser C which is connected by a switch 207 when a relay coil 208 is energized by the immersion contacts 20, Fig. 10. Charge is derived from a thermal battery (300) energized by a percussion cap (302) when this is struck by a hammer (307) normally held by pin (310) which is withdrawn by pulling the lanyard 16 to energize the apparatus (Figs. 11-13, not shown).

Rotation of control line 11 and hence control member 11a in, e.g., a clockwise direction causes a like clockwise movement of control surface 12 causing the aircraft to climb in flight. The means for controlling the flight of the aircraft also serve automatically to correct any changes in attitude of the aircraft which are not caused by deliberate rotation of the control line. The aircraft model may be a helicopter in which case the control surface is constituted by the rotor surfaces of the helicopter.
