Abstract: 872,788. Rectifying. DICTAPHONE CORPORATION. Aug. 29, 1958 [Sept. 18, 1957], No. 27830/58. Class 38 (2). [Also in Group XXXIX] The amplifier 38 (Fig. 2) of a dictating machine is supplied with D.C. from mains 18 through rectifier 36, the values of the resistors and capacitors in the network 40 being so chosen that 38 receives the same voltage whether the mains 18 are D.C. or A.C. The relatively heavy intermittent loads taken by the solenoid 34 energized on closure of start-stop switch 12 and the solenoid 50 energized on closure of playback switch 14 are prevented from causing fluctuations in the voltage supplied to amplifier 38 by shunting each of the solenoids by a resistance and capacitor in series 52, 54 and 56, 58, the values of the capacitances being so chosen that connection and disconnection of 34 and/or 50 does not affect the voltage supplied to 38. Solenoid 34 controls a clutch unit 24 which connects the main drive-shaft of the dictating- machine to motor 22. Solenoid 50, when energized, switches the input of amplifier 38 from the microphone to the pick-up head of the machine and the output of the amplifier from the recording head to the microphone which then serves as a loud-speaker. Fig. 4 shows another arrangement in which load 80 may be the amplifier and 96 and 106 the solenoid coils and surge resistors 76, 92, 102 are arranged as shown to reduce the ripple voltage applied to the coils.

Filed: 1939-10-13
Abstract: 535,701. Modulating systems. STANDARD TELEPHONES & CABLES, Ltd., BEATTY, W. A., and SCULLY, C. T. Oct. 13, 1939, No. 27849. [Class 40 (v)] Pulses of the kind utilized in the signalling systems described in Specifications 523,575 and 524,671 are modulated on a carrier wave by causing the wave to vary the intensity of the beam of a cathode-ray tube by which a sound or like signal is converted into pulses. The beam from a cathode 11 passes through a control element 12, focusing anode 13, anode 14, deflecting plates 15, and a ring 16 formed of spongy carbon, to the target 17. The modulating signal voltages are applied to one pair of plates 15, and time-base voltages to the other pair. The beam thus strikes the target 17 for a variable period during each cycle of the time base. The carrier is applied from the circuit 19 to the control element 12 to vary the intensity of the beam, and sets up carrier current in the target circuit 22 so long as the beam is striking the target 17. The output circuit 25 is fed by the circuit 22, and may feed the aerial through frequency-multipliers. Where one edge of each pulse has an amplitude different from the remainder of the pulse, a second target 18 is connected to a further tuned circuit 27 so coupled to the final circuit 25 as to produce the desired amplitude difference. During the fly back period of the time base, the beam may be suppressed by biasing the control element 12 or the generation of the carrier wave may be interrupted.

Filed: 1927-10-20
Abstract: 304,371. Beatty, W. E., (Bell Telephone Laboratories, Iwc.). Oct. 20, 1927. Alloys; dry processes of refining nickel.-Nickel and alloys consisting principally of nickel are refined by bringing the nickel to a molten state and adding thereto a substance comprising one or more of the metals vanadium, tantalum, and niobium. Vapadium may be followed by a small amount of magnesium. Preferably, to the molten metal, an alloy of vanadium and nickel containing about 25 per cent of vanadium is added, the amount added being sufficient to make the vanadium content of the molten bath about 0.25-0.5 per cent. This is followed, shortly before the end of the melt, by about 0.1 per cent of magnesium, preferably in the form of an alloy with nickel. When tantalum is used it is preferably added as an alloy containing about 30 per cent of tantalum and 70 per cent of nickel, the corresponding proportions for niobium being 31 per cent and 69 per cent respectively. The added substances desulphurize and deoxidize the nickel, and at least a portion of the oxides and sulphides formed with the added substances slag off at the top of the bath. The process is useful for treating the magnetic alloys of nickel and iron described in Specification 188,688. Preferably electrolytic nickel having a carbon content not exceeding 0.03 per cent is employed.

Abstract: 1280907 Digital measurement of length GENERAL ELECTRIC CO 11 June 1970 [8 July 1969] 28405/70 Heading G4H Lengths of steel strip joined end to end are passed through a pickling bath with several lengths in the bath at a time and the difference in pulses emitted by two tachometers attached respectively to entry and exit pinch rollers indicates the total length of strip in the bath, but because of slip on the exit rollers the indication is inaccurate. The invention provides a calibration circuit which resets the indication on each strip leaving the bath. In Fig. 2 the difference in the two tachometer pulse trains drives via logic circuit 41 a counter 43 indicating the length of strip in the bath, although inaccurately. For calibration a counter 49 counts pulses from the entry tachometer and upon each fresh strip entering the bath &c. reading is shifted to register 55, and preceding stored counter shifted down by one register. A fresh strip is detected by detecting the joint between strips, at which a marker-hole is then punched and an electric signal simultaneously emitted to effect the above shifting. A photoelectric hole detector detects each strip leaving the bath and causes the successive transfer of the counter and shift register readings to a working counter 61. After each transfer, counter 61 is clocked to zero and counter 43, previously zeroed, simultaneously clocked up so it finally contains an indication of the sum of the length of strip in the tank. Counter 43 is then controlled by the tachometers until the next calibration. If the reading of counter 43 goes below a preset minimum more steel is added and less if counter 49 and shift register stages 55-57 become full as detected by AND gate 71.

Abstract: 1,186,949. Bar-stock feeding. FABRIQUE DE MACHINES ANDRE BECHLER S.A. 14 June, 1968 [29 June, 1967], No. 28487/68. Headings B3B and B3T. In an automatic lathe for feeding bar stock of a polygonal cross-section there is provided at the rear end of the work spindle 3, between the headstock 2 and the bar feed mechanism 5, means for orientating the bar A for insertion into a chuck 4 on the work spindle. The means comprises a tubular member 12 rotatable in bearings 13 and is axially slidable by way of a yoke member 19 which engages with a flanged member 16 secured to the tubular member 12. The member 12 has a flange 12a which houses in suitable bores pusher elements 15 which are radially spaced around the axis of the member 9 inclined axially thereto. The tubular member 12 also carries a disc 27 having axially extending pins 31 which co-operate with a clutch part 28 to engage with teeth 10 on a clutch member secured to the work spindle 3. In operation a polygonal bar is fed into the tubular member 12 and when in a predetermined axial position (see chain dotted in Fig. 2) a fluid or electrically operated device 23 is actuated to pivot the yoke 19 whereby the flanged member 16 contacts the pusher elements 15 which are urged against the springs 14 into engagement with the faces of the bar, the member 12 rotating slightly to adopt the required orientation. The continued movement of the yoke member 19 displaces the member 12 axially whereby frictional engagement between the clutch members 8 and 28 initially occurs and thereafter when the speed between the spindle 3 and member 12 are synchronized the pin 31 engages with the teeth 10 of the clutch portion 8 of the work spindle, the bar and the member 12 hence rotate at the same speed as the clutch 4, the bar being fed axially through the spindle and chuck by the bar feed device 5.

Title: Vacuum deposition of ferromagnetic metal films
IPC: H01F41/20
Filed: 1965-07-06
Abstract: A method of depositing a film of ferromagnetic metal on a substrate (e.g. a tape) comprises heating a ferromagnetic metal in a vacuum so as to evaporate the metal, directing and condensing the evaporated metal on to a substrate to form a first ferromagnetic metal layer, cooling the first metal layer to room temperature, heating further ferromagnetic metal in a vacuum to evaporate the further metal, directing and condensing the evaporated further metal on to the first metal layer at an angle of incidence greater than 45 DEG  to form a second ferromagnetic metal layer, and cooling the second metal layer to room temperature. The first and second layers may each be deposited in a series of bursts so as to increase coercivity of the film.  Ferromagnetic metals which may be used are Co, Fe, Ni, Co-Fe, Co-Ni or Ni-Fe containing between 1 and 74 or 86 and 99% by weight Ni and the balance Fe.  To modify the magnetic properties between 0.5 and 4.0% by weight S may be evaporated simultaneously with the metal. In the examples the substrate is of polyethylene terephthalate. The metal forming the first metal layer may be directed on to the substrate at an angle of incidence greater than 45 DEG , the first metal layer may then be cooled to at most 60 DEG  in a non-oxidizing atmosphere and thereafter cooled to room temperature in an oxidizing atmosphere.  Alternatively, the first metal may be directed on to the substrate at normal incidence.  Where an isotropic magnetic film is to be produced, the first metal layer is cooled in an oxidizing atmosphere from a temperature greater than 150 DEG C.  This produces a partially oxidized film.  Where an anisotropic film is to be produced, the first metal layer is cooled in a non-oxidizing atmosphere to below 60 DEG C. prior to exposure to an oxidizing atmosphere.  The apparatus in which the method is carried out may be the same as that disclosed in Specification 1,104,708.  Fig.2 (not shown) illustrates apparatus for continuously producing magnetic tape. It comprises in sequence a vacuum evaporation chamber (70), a cooling chamber (74), a vacuum evaporation chamber (72) and a cooling chamber (76).  The Specification recites claim 1 of Specification 1,104,709.
