Title: Apparatus for use with a cathode ray oscillograph to display simul taneous representations of two signals
IPC: A61B5/0432
Filed: 1971-10-29
Abstract: 1368769 Cathode-ray tube displays SIEMENS AG 29 Oct 1971 [31 Oct 1970] 50657/71 Heading H4T Signals derived from two monitoring processes intensity modulate the beam of a line-raster scanned cathode-ray display tube such that the two signals are displayed on separate non- overlapping screen areas. The invention is described in connection with the display of an ultrasonic pulse cardiogram (UCG) and an electrocardiogram (ECG). As shown in Fig. 1 the UCG is produced by means of a transducer 1 pulsed by a H.F. generator 3 controlled by a pulse train U (Fig. 2) from a clock 4, received reflected signals being supplied via amplifier 5 to an input 6 of a gate 7 whilst the ECG is produced by means of an ECG electrode 2 the output signals after amplification in 10 controlling a monostable 11 to produce an output pulse U 4  (Fig. 2) the duration of which depends on the amplitude of the ECG signal, such pulse being differentiated in 12 and supplied to an input 13 of gate 7. The clock pulses U 1  also control a monostable 14 producing the pulse train U 3  (Fig. 2) which "opens" input 6 and "closes" input 13 of gate 7 so that during approximately 70% of the duration of each line scan (waveform U 2  produced by sweep generator 16 under control of clock pulses) the UCG signal intensity modulates the beam of tube 9 whilst during the remainder of the scan the ECG signal provides the modulation of the beam the field deflection of which is produced by sweeps generator 18 synchronized by the ECG signal. Figure 3 shows the display of a UCG 21, (together with curves 23, 24, 25 and 26 produced by echo pulses derived from body areas surrounding the heart) and of a ECG 22. The displayed signals may, alternatively, consist of an ultrasonic encephalogram together with an electro-encephalogram or of a UCG with respiration-proportional voltage.

Abstract: 1,105,240. Aligning vehicle wheels. BISHMAN MANUFACTURING CO. Nov. 21, 1966 [Dec. 1, 1965], No. 52104/66. Heading G1X. Apparatus for aligning vehicle wheels comprises a support for a wheeled vehicle (not shown) having work stations positioned adjacent each wheel of a vehicle an elongated reference marker, as 13, at each work station, the reference markers being disposed parallel to each other, a portable gauge 30 for attachment to the hub 53 of a vehicle wheel and having an aperture containing an optical reference line 37 defining an axis 54, and a portable adjustable reference member 20, having a base member 21 with grooves on its underside for location on the elongated reference marker, as 13, at the particular work station, and an upper adjustable member 25 pivotally mounted for rotation about an axis 38 on the base member 21 and having indicia lines marked on its upper surface for alignment with the reference line 37. In use the vehicle is driven on to the support and the gauge 30 is fixed e. g. by magnetic attraction to a machined face on one of the rear wheels of the vehicle. This machined face is assumed to be parallel to the centre line 46 of the vehicle. The reference member 20 is placed on the appropriate reference marker 13 and the upper member 25 rotated until the indicia lines thereon are in alignment with the line 37 on the gauge 30. The gauge 30 and member 20 can then be moved to the other work stations to check the alignment of the other wheels of the vehicle. The part of the gauge which contacts the wheel are made from two relatively rotatable members so that the angular relationship between the line 37 and the face of the gauge contacting the wheel can be adjusted, to enable a check to be made on the correct toe-in angle of the front wheels of the vehicle. In an alternative arrangement the line 37 is arranged to be adjustable about a vertical axis on the gauge 30 and in this case the member 25 remains stationary on the base 21 during adjustment. Also if desired wires 55 may be used in place of the fixed reference markers 13 at each work station.

Abstract: 1452132 Electronic switching system COMPAGNIE ELECTRO-MECANIQUE 20 Nov 1973 [20 Nov 1972] 53886/73 Heading G1N The invention relates to an electronic switching system employing an oscillating proximity detector responsive to limited movement of an operating member which causes the oscillator to start or stop. According to the invention the oscillator has positive and negative feedback applied by inductive couplings and the operating member varies one of these couplings. As shown Fig. 1. the oscillator coils are arranged as a transformer with a primary 1 and differentially connected secondaries 2, 3 on a magnetic core 5. A tubular aluminium operating member 7 slides over winding 3 to reduce positive feedback. A tube 6 allows initial adjustment of the negative feedback coupling between coils 1 and 2. An untuned circuit is used (no capacitor) to provide good temperature stability. The signal is picked off from the oscillator circuit by an overwinding 4 and used to control a power switching transistor, Fig. 2 (not shown). Modifications The aluminium tube 7 could be replaced by a ferromagnetic tube (to increase the coupling). The inductor unit may be screened by a shroud 8 to avoid external interference.
