Title: Improvements in magnetostrictive vibrators
IPC: G01S1/72
Filed: 1932-07-26
Abstract: 405,620. Receiving and detecting audible signals. PIERCE, G. W., Harvard University, Cambridge, Massachusetts, U.S.A. July 26, 1932, No. 6157/33. Divided on 405,613. [Class 118 (ii).] A magneto-strictive apparatus used, for instance, for the reception and production of sonic or supersonic sound waves comprises a vibrating element forming a shield for the coil which has an external field. In the arrangement shown in Figs. 2 and 3, a number of sealed tube cores 2 of magneto-strictive material, such as nickel, are arranged close together on a supporting base 58, each core enclosing a coil 10 which may be connected in series or otherwise. Sound waves received by one or a group of these enclosed elements arranged under water, as shown in Fig. 1, or otherwise produce electrical oscillation in the wire 12, 14 connected to a tuned circuit with means for amplifying connected to a loudspeaker 44. A magneto-strictive device of the above type may be employed with a cone or plate shaped diaphragm described in Specification 405,613. In transferring energy from one electrical circuit to another, coils 70, 10, Fig. 4, are arranged respectively outside and inside a tubular magneto-strictive vibrator 2 which acts as an electromagnetic shield preventing action of one coil on the other except at or near the frequency of the vibrator 2. A sound-transmitting apparatus may consist of a number of magneto-strictive elements constructed in accordance with the invention and connected through thermionic amplifier to a magneto-strictively-controlled oscillator which may be of the type described in Specification 313,031, [Class 37, Electricity, Measuring &c.]. The coils 84, 86, 88, 90, 92, Fig. 6, arranged within a magneto-strictive tube 2 are so spaced and connected to a battery 98 and source 94 of alternating current that the coils act to reinforce the vibration of the core 2 as a unit, some of the coils, for example 84, 88, 92, being connected to produce opposite fields to the others for this purpose.

Title: Improvements in or relating to multipole electric networks
IPC: H04J1/08
Filed: 1952-03-10
Abstract: 705,628. Multiplex transmission. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 10, 1952 [March 13, 1951]. No. 6162/52. Class 40 (4) [Also in Group XL (b)] A multipole network for coupling channels I, II and III, whose pass bands do not overlap, to a common channel O, comprises a quadripole 1, 2 or 3 for each separate channel all coupled to channel O, and each of the circuits coupling a channel quadripole to the common channel includes a reactance, which compensates the reactive part of the impedance measured between the terminals of the common channel within the pass-band of the channel quadripole concerned. In the arrangement shown in Fig. 2, a correction network Zo, comprising two series circuits is placed across terminals O. In the absence of impedances Zs, an impedance measured across terminals O is found to consist of a real part not varying with frequency and an imaginery part varying with frequency. Series circuits forming impedances Zs are inserted in series with each quadripole to compensate the imaginary part of the impedance. By a dual transformation, the circuit of Fig. 2 can result in the circuit of Fig. 4, wherein the impedances have become parallel circuits and are in parallel where they were previously in series, and vice versa.

Title: Improvements in or relating to party-line telephone systems
IPC: H04Q5/00
Filed: 1920-03-01
Abstract: 168,337. Hastings, R. C. M. March 1, 1920. Drawings to Specification. Party-line systems and apparatus.-In a lockout party-line system, with ratchet-operated substation selectors controlled by impulses from an exchange, the selector opens a shunt circuit round the receiver at the wanted substation and closes a local bell circuit. When the called subscriber answers, a contact is momentarily closed by the rise of the switch-hook to energize a magnet which opens the bell circuit by tripping a contact-member forming part of the selector. After conversation the selectors are stepped forward by impulses from the exchange until they reach their normal positions, in which they are arrested by stops. The construction of the selectors is such that if either subscriber, after conversation, omits to replace his receiver on the hook this does not prevent him from being selected and rung up by the exchange. All the local bell circuits can be closed simultaneously by relays energized by alternating current from the exchange. The system and apparatus are the same as described in Specifications 168,338 and 168,568, in which other features are claimed.

Title: Refractory lining for melting pots used in the alumino-thermic extraction of metals
IPC: C04B38/02
Filed: 1944-04-15
Abstract: A porous refractory lining or a binder for refractory bricks for a metal melting-pot for use in the extraction of metals by reduction with aluminium, silicon, or magnesium, is prepared by temporarily binding a powdered refractory, such as dead-burned magnesite and/or dolomite, with or without the addition of partly-burned components, corundum, or silicon carbide, with water to which may be added other materials capable of generating a gas on heating, e.g. a carbonate, so that, when the reaction is started in the pot, the binder is evaporated or decomposed and renders the lining porous, the surface pores being then filled by the slag resulting from the reaction.  The gas generated must not be in such great amount as to cause strains in the lining. According to an example, to 100 parts of a ramming mixture consisting chiefly of dead-burned magnesite are added 10 parts of a 5 per cent sodium carbonate solution, and the mixture is applied as a lining to a metal pot and dried until the water-content is about 0.5 per cent; a reaction is then started in the pot.

[Class 38 (v)] A switch for use in signalling circuits has a press-button 1, preferably in the form of a lamp, which on depression depresses contact springs b, d of a contact spring set a .. e and on release moves to its initial position accompanied by the spring b. The spring d is formed, however, with a slot arranged when the button is in the depressed position to be engaged by a pivoted hook 3, Fig. 2. The lower pair of contacts remain in position after release of the press-button until the catch is released by a subsequent turning movement of the press-button which then causes an arm 4 to engage behind the hook 3 and release it from the contact. As an alternative the hook 3 may form the armature of a releasing electromagnet which may be operated from a remote point. The hooked catch may itself act as a contact arm and may be caused to engage a relatively fixed contact spring during the rotation of the pressbutton. This arrangement may be used independently of or may be combined with, an arrangement similar to that previously described. Specifications 430,816 and 437,976 are referred to.
