Abstract: 902,378. Marker tabs for recording tape. METRO - SOUND MANUFACTURING CO. Ltd. Dec. 16, 1959 [Dec. 29, 1958], No. 41859/58. Class 73. A marking device for recording tape to indicate the beginning and end of recordings comprises an adhesive tab 2, Fig. 1, of sheet material, the thickness of the tab being such as to permit passage past the usual recording and playback heads of the tape-recorder and the dimensions of the tab being such that it may be secured substantially wholly across the non- playing face of the tape and bent about an edge of the tape for securing substantially over an upper or lower track area of the playing face of the tape, as shown in Fig. 3. The tab may be of the same material as the tape with or without the magnetic content and the vertical edges 7, 8 may be chamfered to facilitate easier passage through the tape recorder. A suitable adhesive for the tab is rubber latex which will peel off substantially without trace. The tab is distinctively coloured, e.g. a single colour to denote upper track recordings or a two-colour pattern for lower track recordings, and an index may be provided in conjunction with the tabs to enable the user to keep a record of the position and other information relating to the recordings. The tabs may be arranged to tear or peel off a backing-sheet which may be incorporated in the index.

Abstract: 1,068,599. Transmitting temperature measurements from moving parts, electrically. KARL SCHMIDT, G. m. b. H. Oct. 14, 1964 [Oct. 16, 1963], No. 41970/64. Heading G1N. Measurements of physical quantities (e. g. temperature) sensed by a transducer (e. g. a resistor, thermocouple, or inductor) on a moving part are transmitted via an inductive coupling from the moving part to a stationary instrument. In Fig. 3 transducers 2 on a piston are in circuit with hollow air cored secondary coils 11 also fixed to the piston. Stationary primary coils 5 energized from a high frequency A. C. supply 7 are slidable within a corresponding coil 11 and are intermittently coupled therewith as the piston moves. When for example the position of the piston is such that left hand side coil 11 surrounds the corresponding coil 5 the coupling is maximum and the impedance of the circuit of coil 11 referred to the primary coil 5 affects the reading on a meter 6, thereby giving an indication of the environment of the left hand side transducer 2. The right hand coil 5 co-operates alternately with each of two coils 11. In an embodiment Fig.4 (not shown) the secondary coils are mounted on a piston rod and in embodiments Figs. 1, 2 (not shown) are on a rotatable shaft. In both cases at the instant of maximum coupling a secondary coil is opposite a primary coil, their axes coinciding. In a further embodiment Fig. 5 (not shown) the temperature of a piston at several points is sensed by thermocouples the output of which is applied to a control winding to influence the magnetic field of the associated secondary coil. Temperature sensitive resistors are located adjacent the cold reference junctions and are connected to compensate for change in temperature of the reference junctions. The measuring transducers may be connected in a bridge circuit (not illustrated).

Core 9 is a permanent magnet and its position relative to member 3 is adjusted until the temperature coefficient of the vibrator device is negligibly small. The normal running frequency is then determined by the shape of member 3 and this frequency can be altered within small limits by adjusting the position of soft-iron core 10 relative to member 3 or by altering the oscillator frequency by means of variable resistor VR. The fixed parts of the device may be mounted on a printed circuit board 4.

Abstract: 1339387 Pulse thresholding circuits COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT - ALCATEL 13 Sept 1972 [22 Sept 1971] 42522/72 Heading H3T A pulse shaper comprises a differential amplifier having an input circuit substantially as shown. When the instantaneous level of an input pulse exceeds a threshold level provided by potentiometer R 1 , R 2  the amplifier output switches. The voltage across the capacitor and the lower input voltage of the amplifier follows a diode voltage drop behind the rising edge of the pulse. At the trailing edge the capacitor voltage is substantially maintained and the amplifier switches back when the voltage falls below this voltage. The pulse output width is thus independent of the pulse amplitude.

Abstract: 1,117,242. Electric meters; recording apparatus. CLEVITE CORPORATION. Oct. 19, 1965 [Nov. 12, 1964], No.44223/65. Headings G1J and G1Q. In a moving coil galvanometer in which rotary displacement of the coil is converted by suitable linkwork into rectilinear movement of a recording pen tip, the pen tip displacement is not linearly related to the angular deflection of the coil. To correct for this non-linearity the invention provides a transducer consisting of an armature 75 which moves with the coil (not shown) in an arcuate path adjacent a generally Y-shaped magnetic member 142. Associated with this member are input and output coils (not shown) the flux linkage between which varies with armature position. The magnetic member is of laminated construction, some of the laminations having the full Y-shape shown at L in Fig. 5 and others being truncated as at L<SP>1</SP>. The variation of flux linkage between the transducer coils is thus different at large deflections than at small ones, so that the output is non-linearly related to angular deflection. This output is fed as a feedback signal to the galvanometer input, and with suitable proportions of the two types of laminations it can be ensured that the coil response is non-linear by the amount necessary to correct for the non-linearity of the coil to pen tip linkage. The feedback circuitry Fig. 2 (not shown) is more fully described in Specification 1,117, 243.
