Title: Recording and/or Reproducing Apparatus
IPC: G11B27/30
Filed: 1967-09-06
Abstract: 1,191,740. Recording and playback. PHI. LIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 Sept., 1967 [9 Sept., 1966], No. 40674/67. Heading G5R. [Also in Division G3] Signals derived from a microphone 3 are amplified by a multistage amplifier 1 and passed to a magnetic head 5 for recording on a carrier which is driven by an electric motor 7. A battery 6 supplies the motor whose speed is stabilized by a centrifugal governor 8. When a manual switch 10 is closed, pulses due to the intermittent operation of the governor are passed through a circuit 13 comprising blocking capacitors 14 to the input 9 of a stage of the amplifier. These pulses are then transferred to the head 5 and recorded on the carrier in the form of reference marks for indicating the start of a recording or for correction of a recording. In another arrangement, the head reproduces signals from the carrier for amplification and application to a loud-speaker. A.C. signals are derived from the motor and transferred to the amplifier through a circuit comprising a shortcircuit switch. When this switch is opened, a tone is heard through the loud-speaker which lowers in pitch as the battery voltage decreases and ceases when the battery is completely discharged. This is due to the decrease in frequency of operation of the centrifugal governor when the battery voltage falls. The motor may be connected to a resistor-diode bridge network whose output represents deviations of the motor voltage from a standard value and is applied through a transistor to control a power transistor in series with the motor. In this case, fluctuations due to commutator ripple are detected and applied through the connection 13 to the amplifier 1. The system may be provided with switches for changing between recording and playback operation, a resistor being included in the motor circuit for current control. The connection between the motor circuit and amplifier comprises a threshold device formed by a resistor and diode in parallel with the power transistor so as to provide a sharp cut-off at low values of the tone-producing signals passing from the motor circuit to the amplifier. In another arrangement, the threshold device comprises a biased diode, the response threshold value being adjustable by means of a voltage divider.

Abstract: 1,215,030. Holography. INTERNATIONAL BUSINESS MACHINES CORP. Aug.27, 1968 [Sept.11, 1967], No.40818/68. Heading G2J. Apparatus for forming an object using non- coherent radiation comprises means for selecting radiation emanating from a sequence of elemental portions of the object, beam splitting means for splitting radiation so selected into two beams so as to produce a pair of synmetrical conjugate images and superposing means for causing an interference pattern formed from the two beams to be recorded for each portion of the sequence on a recording medium in such a way that the hologram so formed is substantially linear having a linear intensity distribution corresponding to the aggregate Fourier transforms appropiate to the conjugate images. The output may be from a cathode ray tube illuminating a digital chip 16 comprising a series horizontal lines 14 each composed of transparent and opaque verticals. Light from the chip is collimated by lens 18 and directed to a beam splitter 20. This comprises two prisms 22, 24 having plane parallel facing surfaces 26, 28 separated by a space less than the wavelength of the radiation. The incident beam thus splits, one beam 36 being three times internally reflected at face 26 and another beam 38 passing into prism 24, and being relected at mirror face 42 and face 28. The beams 36, 38 pass to a lens 44 which creates conjugate images 46, 48 of the chip 16. The light from these then passes through a spherical lens 54 and cylindrical lens 56 wherein point pairs, e.g. 60, 62 of the images 46, 48 form interference fringes which are recorded as a horizontal line only on a roll of film to give a hologram. In reconstruction collimated light is shone on to the hologram, the light from which then passes two lens equivalent to lens 54, 56 to give separated images of the orinigal object.

A fluid pressure transducer which utilizes the differential pressure across an orifice in a pipe line to measure fluid flow rate, comprises a measuring diaphragm 20 (Fig. 2) and a pair of seal diaphragms 32, 36 which co-operate to form two sealed compartments in a casing 10. The compartments are filled with a silicone liquid, introduced initially through tubes 38, 39, which transmits pressure from the seal diaphragms to the measuring diaphragm, the surfaces of the seal diaphragms outside the compartments being in communication with the pressure source via passages in connecting flanges 12, 14. The measuring diaphragm has stiffener discs 22, 24 and attached to the disc 24 is the left hand end (as shown) of a nickel alloy cylindrical spring 26 detailed Fig. 3 (not shown) the other end of which is attached to the casing 10. Within the spring are a pair of E-type cores Fig. 4 (not shown) carrying coil windings and supported on brackets secured to the casing and to the other end of the spring. In an air gap between the cores, extending diametrically across the spring and medially thereof is a ferrite rod armature. This is supported by brackets attached to the movable end of the spring, so that movement of the diaphragm moves the armature and varies the ratio of the air gaps between the armature and respective cores, thus varying the inductance ratio of the coils, which may be connected in an external circuit (not shown) to provide a measure of the differential pressure at diaphragm 20 and of the fluid flow rate. Each of the diaphragms 32, 36 (Fig. 2) has an enclosed chamber defined by an inner and outer membrane. Metal filter plugs 40, 42 (e.g. porous sintered bronze) are fitted on the respective inner membranes which permit fluid to flow in and out of the seal diaphragms at a controlled rate. The casing 10 has contours which mate with the contours of the seal diaphragms. All the diaphragms may be of berylium copper or stainless steel. Stops are provided to limit movement of the measuring diaphragm as a protection against over-pressure.

. Oct. 7, 1965 [Oct. 23, 1964], No. 42584/65. Heading H3T. A circuit for regenerating and/or re-shaping pulses comprises an input and delay stage A, a shaping stage B and a bi-stable circuit A<SP>1</SP> with a tunnel diode 12 and connected between the stages A and B. Input signals S 1 , occupying random ones of equal successive time periods, and clock pulses b1, occurring in the latter part of each time period, are applied to AND gate 1, 2. The presence of both signals causes transistor 5 to saturate and its collector voltage drops for slightly longer than the duration of the block pulse, because of charge storage in transistor 5. The pulse on the collector of transistor 5 is shaped by a coupling consisting of capacitor 6 and diode 7, resulting in a small positive pulse at K in the time period proceeding that which S 1  occupies. The positive pulse triggers the tunnel diode 12 to its upper stable state. At the end of this period, a short negative clamping pulse i re-sets the tunnel diode. The delayed pulse thus produced at h is amplified by transistor 15 of shaping stage B, the clamping pulses being applied to the collector of transistor 15 to accurately define the trailing edge of output signal S<SP>1</SP> 2  which is passed to power amplifier C consisting of emitter follower 21. The output pulse amplitude is independent of the deformation of the input signal S 1 , and hence the amplitude of the signal at h, since it only depends on the difference between the stable states of the tunnel diode. Resistor 8 may be replaced by a diode, for example a point contact diode, with its cathode connected to diode 12.
