Abstract: 1,245,767. Monitoring pulse-rate. A. D. HERMAN and H. Z. MARX. 1 Oct., 1968, No. 46560/68. Heading ASK. [Also in Divisions G1, G3 and H1] A device for indicating and warning of deviations from a norm of a cardiac pulse rate includes two watch mechanisms, a reference one 14 driven at constant speed by a known arrangement and a controlled one 11 of which the speed is controlled by the wearer's pulserate, an alarm being actuated for a predetermined difference between the speeds. The watches are worn on a bracelet (21) Fig. 1 not shown carrying a pulse actuated switch (9) Fig. 2 (see Division H1) so that switchclosures actuate a solenoid armature to drive the shaft 16. For a given pulse rate the speed of the controlled watch is synchronised with that of the reference by adjusting the armature stroke by means of limit stop nuts (37a) Fig. 5, not shown. The watch shafts 16, 17 are connected by a differential gear train 15 so that respective bevel gears 51, 52 rotate in opposed directions so that if their rotary speeds differ the idler pinion 54 moves arcuately along the cage 55, to trip at either end thereof an alarm, warning of a fast or slow pulse rate. Manual synchronisation of the watches is effected by drawing the idler pinion out of mesh with the bevel gears by means of a knob 60. An alternative embodiment utilises crown gears instead of bevels in the differential gear train.

In one construction, Fig. 2, the assembly 17 comprises outlet guide vanes of the fan rotor blades (13), Fig. 1 (not shown) of a gas turbine front fan engine. The vanes are arranged in a helical row with a strut 16 disposed between the most upstream vane 20 and the most downstream 21. The strut 16 supports the fan cowling (15) and is arranged so that its leading surface 26 is substantially parallel to the direction of flow thereover. In a modification, Fig. 5, angularly spaced struts 42 extend between an upstream helical row of intermediate pressure compressor outlet guide vanes 36 and a helical row of high-pressure compressor inlet guide vanes 37. A main shaft bearing support member (41), Fig.4 (not shown), extends radially through each strut 42. The angle subtended to the diametral plane of the flow duct by the row of vanes 36 may be the same as or differ from that subtended by the row of vanes 37. A mathematical derivation of the angle is given. In a further arrangement, Fig. 6 (not shown), most of the guide vanes (55) in a row are disposed in the diametral plane of an annular fan duct (56) and only three vanes (62) are helically arranged adjacent the leading surface (58) of a strut (57).

Abstract: 1,128,297. Combined sighting and laser range-finding arrangement. ERNST LEITZ. G.m.b.H. Nov. 8, 1965 [Nov. 7, 1964], No. 47213/ 65. Heading G2J. The arrangement comprises a laser rangefinder including a laser transmitter 16 and a laser receiver 5 for receiving laser light reflected from a target and a sighting device including an eyepiece 8. A beam-divider 1 is positioned to direct light from the target towards the receiver 5 and an optical system 14, having two optical components, is disposed in the transmitted laser beam 15. A reticule plate 9 is mounted in front of the beamdivider 1 and an image of the target is formed centrally thereon by lens 3. The plate is coupled to one component 13 of the optical system 14 for displacement in a plane transverse to the optical axis of the system in accordance with the output from a metering device which is connected to the laser receiver 5 and operates a control 17. Such movement of plate 9 is a measure of the target range. Re-positioning of the target image centrally of the plate is effected by movement of the sighting device together with a weapon attached thereto so as to adjust for the required elevation angle for firing a projectile. Optical means are disposed in the path of light from the target to block all laser light except that corresponding to light emitted by the laser transmitter 16. Such means may comprise coating 12 on the surface of the reticule plate 9 which is permeable to visible light only, laser light of the required divergence being transmitted through a central aperture 11 in the coating 12. In a second embodiment, the optical means comprises a stationary diaphragm provided between the beam-divider 1 and the laser receiver 5. Two optical lens members are located between the beam-divider and the diaphragm and are arranged to image the plate 9 in the plane of the diaphragm and to render light parallel between the lens members, the plate 9 being displaceable jointly with the optical component 13 and with the lens member nearer to the plate. The plate 9 and coupled optical component may also be displaceable in a direction perpendicular to their transverse displacement and to the axis of the transmitted laser beam.

Title: Ultrasonic detection apparatus

Abstract: 1367295 Ultrasonic object-detection apparatus; automatic gain control MATSUSHITA ELECTRIC WORKS Ltd 14 Oct 1971 [15 Oct 1970 26 May 1971] 47861/71 Headings H4D and H4R In an ultrasonic system for detecting the presence of an object in the propagation path between a transmitting transducer (energized by the amplified output of an oscillator) and a receiving transducer, a positive feedback signal is derived by amplifying then rectifying the receiving transducer output and is applied as a gain control signal to control the transmitted ultrasonic signal strength. This enhances any change in the received signal strength caused by the object presence and ensures positive operation of a switching circuit by the system. In the Fig. 6 embodiment, oscillator A energizes transmitting transducer V1 via variable gain amplifier H. The output of receiving transducer V2 is amplified at E then rectified at F to give a negative D.C. voltage on capacitor C8 which, together with a positive supply voltage, controls the base current of transistor Tr2. If the received ultrasonic signal strength falls the C8 voltage is reduced and Tr2 turns on, thus shunting the input to Tr3 base and at the same time increasing the current through a diode D1 and hence increasing negative feedback through D1. The transmitted ultrasonic signal level is thus reduced and relay drive transistor Tr6 is turned on by current through R20, having previously been held non-conducting by a negative voltage derived by rectifying at D5 the voltage across the transmitting transducer V1. Resistors R6 and R10 prevent the transmitted signal level from being reduced below a threshold which would cause the object-detection apparatus to become inoperative. The gain of amplifier E can be adjusted by potentiometer VR to allow the use of various propagation path lengths. The received signal strength is monitored on meter M. A variable attenuator and fixed gain amplifier may be used in place of variable gain amplifier H (Fig. 3B, not shown), and a switching circuit may be actuated by the rectifier F output.
