Title: Improvements in or relating to portable or field telephones
IPC: H04M1/18
Filed: 1957-04-11
Abstract: 860,226. Substation equipment. SALZER, A. April 11, 1957 [April 11, 1956], No. 11946/57. Class 40 (4). The calling signal of a field telephone set is produced by discharging a capacitor across the line, the capacitor being charged from a local battery by means of a transistor oscillator and a step-up transformer. As shown in Fig. 1, when a speak-key 20 is pressed to energize transistor 12 from battery 11, full depression of a calling- key 23 connects a feed-back coil 8 in circuit to cause transistor 12 to oscillate at audiofrequency. The oscillations are passed to the line 1, 2, by winding 5 of transformer 3, and over winding 6 and rectifier 18 charge capacitor 19. On the return motion of the calling-key 23 switch 25 momentarily connects capacitor 19 across the line. With the speak key 20 pressed, transistor 12 is connected up as an amplifier for carbon microphone 10. As shown in Fig. 2, when calling-key 47 is fully depressed transistor 12 is connected to oscillate at audio-frequency and over winding 34 of transformer 30, capacitors 38 and 40, and rectifiers 37, 39, charges capacitor 41. On return motion of the calling- key 47 it momentarily connects capacitor 41, in series with an equal capacitor 42, across the line so that half the charge is pulsed through the line. When the calling key 47 is next fully depressed switch 50 connects capacitor 42 directly across the line and in consequence discharges the remaining half of the charge across the line but with opposite polarity. In this embodiment the transistor 12 is not connected as an amplifier when the speak key 43 is pressed. Alternating pulses may be applied to the line in Fig. 1 by driving a ratchet-wheel by a pawl on the calling key, the wheel controlling contacts which alternately reverse the connections of capacitor 19. In Fig. 2 a ratchet-wheel may be driven by both the press and release movements of the calling key to reverse the connections of capacitors 38 and 40 which are discharged alternately and directly across the line. For reception of calling signals a slugged relay may be incorporated to connect the transistor oscillator to the local receiver as a tone generator for a predetermined period after the reception of each pulse. The telephone may be constructed as a combination handset with the circuit components contained in the handle on which the speak and calling-keys are mounted.

Title: Improvements relating to the manufacture of ferromagnetic metal particles
IPC: H01F1/06
Filed: 1961-04-04
Abstract: Ferro-magnetic particles are produced by electrolytic deposition from electrolyte containing iron on the surface of a liquid metal cathode, e.g. mercury, and introducing below the liquid metal surface a supply of the liquid metal whereby the floating layer of deposited magnetic particles overflows and is then separated into magnetic and non-magnetic material. A cell 1 filled with electrolyte to level 30 is provided with an inner open top cathode vessel 2 containing mercury and above which is mounted an anode 4.  A vertical tube 33 discharges mercury fed from a reservoir 15, by a solenoid-operated valve 26, below the surface of the mercury in the vessel 2, and the floating layer runs off through an S-bend 5 into a magnetic separator 32.  This separator comprises an inclined rotating screw conveyer 6 having notches at the edge of the screw and mounted in a casing surrounded by magnets 7. The magnetic particles are caught in the notches of the conveyer, and the separated mercury flows into a reservoir from which it is pushed up a tube 13 by water pressure. The magnetic particles progress to the left through a furnace 8 where they are age-heated at 200  DEG C. for a few minutes and any occluded mercury is distilled off.  Cooling condensers are mounted <PICT:0977459/C6-C7/1> at 9, and an inert gas is introduced to the separator at inlet 11. The ferro-magnetic particles which are either iron or iron-cobalt alloy have a ratio L/W of 1.5 to 1 and are of width 100-1000<\>rA.  They are mixed with a non-magnetic material, e.g. a thermoplastic resin, lead or lead alloy, the particles are then orientated, and then pressed to form a compact body. In a modified apparatus a series of cathode vessels 2 are used and the mercury feed from reservoir 15 is controlled by a rotating funnel-shaped member having an outlet at its shallow end which is eccentric and passes over a series of feed tubes supplying mercury to the series of cathode vessels at regular intervals.
