Title: Improvements relating to electrical transformers or couplers
IPC: H01F21/12
Filed: 1927-10-04
Abstract: 303,541. Twort, F. W. Oct. 4, 1927. Transformers.-Radio circuits are coupled together by a transformer with two or more windings so arranged that some or all of the turns or conductors of one winding are shielded by the corresponding conductors of another winding, the field of each shielded conductor having no direct access to adjacent conductors of the first winding nor to any conductor other than the corresponding conductor of the second winding. The conductors of the second winding may enclose those of the first. In a high-frequency transformer, the secondary comprises a copper tube c, Fig. 5, wound helically, in notches in longitudinal ribs b on a cylindrical former a, Fig. 6, and the primary k comprises a fine wire within part of the tube c and separated therefrom by an insulating tube or coating. The lower end of the former a carries evenly spaced contacts detachably engaged by protruding spring contacts g, Fig. 2, on a base e of the same shape as the former a, the circuit wires of the radio set being soldered to tabs h on the contacts g. The lower half c<2> of the secondary c is connected as in Fig. 6 to diametrically opposite contacts OS, ST<2> and the upper half c<1> to similar contacts IS, ST<1>. The contacts IS, OS form the terminals of the secondary and are thus connected to points at the centre of the winding the extreme ends of which are directly connected by joining the contacts g corresponding to the contacts ST<1>, ST<2>. Similarly, the primary winding comprises symmetrically arranged halves at the lower and upper end of the secondary, the extreme ends being joined together at k<1> and the ends nearest the centre of the former a being connected to diametrically opposite contacts IP, OP forming the terminals of the primary. The parts of the secondary not enclcsing the primary need not be hollow. The windings may be shielded by an axially adjustable metal cylinder within the former. In a high-frequency amplifier for short wave lengths, the primary is connected in an aerial or anode circuit, the connected terminals ST<1>, ST<2> are connected through a high resistance to the filament of the next valve, and the terminals of the secondary are connected to the grid and neutralizing condenser. In modifications, a reaction coil may be arranged in the parts of the tube c not occupied by the primary k or as a separate winding. In another modification, more than two concentric conductors are employed, the primary conductor k being hollow to enclose another winding. In other modifications, the primary may comprise a tubular conductor enclosing the secondary or the tubular conductor is replaced by a strip wound around or folded over the other conductor. Specification 288,379, [Class 40 (v), Wireless signalling &c.], is referred to.

Title: Improvements in or relating to electric encoding keyboards
IPC: H04L13/16
Filed: 1963-07-02
Abstract: 1,020,013. Electric selective signalling. COMPAGNIE DES MACHINES BULL. July 2, 1963 [July 5, 1962], No. 26287/63. Heading G4H. [Also in Divisions B6 and H2] In a keyboard having keys for the selective energization of a number of electric conductors, depression of a key depresses an actuating bar which depresses those of a number of notched encoding bars extending transversely beneath the actuating bar which do not possess a notch immediately beneath the actuating bar, depression of an encoding bar causing an intermediate member 56 (Fig. 3b, not shown) to be engaged in a groove 60 (not shown) in the movable armature of an electromagnet and then closing contacts 52A (Fig. 3a, not shown) to energize the electromagnet to pull the armature and engaged intermediate members in such a way that each of the latter closes a corresponding contact 57 (not shown), movement of the armature preventing further encoding bars being depressed as long as the electromagnet is energized. Once energized, the electromagnet remains energized for a time dependent only on the discharge time of a condenser (circuit details in Fig. 18, not shown). The intermediate members and the armature are pivoted, and each intermediate member has a split head 58 (not shown) engaged by the corresponding encoding bar. The keyboard may be used for feeding alphabetic or numerical data to an accounting, typewriting or statistical machine, an electronic computer, or a card or record-tape puncher or to several of these successively through switching means (no details). To change the code combinations, the set of encoding bars may be replaced as a unit, or displaced longitudinally in the machine to one of three positions. The latter is done by depressing one of three keys (marked N for normal, P for punching and M for capitals)-mechanical details in (Figs. 12-15 not shown)-or by energizing one or neither of two electromagnets (one shown in Fig. 19, not shown). A pilot lamp is provided for each of these two magnets. A simpler arrangement with two keys and two positions is shown in (Figs. 9A, 9B not shown). Some of the keys close switches of the type RC (Fig. 2, not shown) as well as depressing actuating bars. The keys M, N, P each close an electric contact pair on being depressed. The space bar on the keyboard rotates a shaft when depressed, to close a contact pair 144 (Fig. 7, not shown). Parts of the keyboard can be put out of circuit by switches I1 ... I7 (Fig. 17, not shown) actuated manually or by electromagnets. A device 34 (Fig. 2, not shown) comprising rollers prevents more than one key being depressed at a time.

Title: Improvements relating to apparatus for plotting the directional characteristics of wave propagating and/or receiving devices, such as radio aerials
IPC: G01R29/10
Filed: 1947-10-01
Abstract: 647,064. Measuring sound and like vibrations. MILLER, C. W., MILLING, M. C. CROWLEY-, and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 1, 1947, No. 26531. [Class 118 (ii)] [Also in Groups XXXIX, XL (b) and XL (c)] In apparatus for determining the directional characteristics of wave propagating and/or receiving devices, the device under test is caused to transmit waves to or receive waves from a co-operating device and is moved angularly with respect to said device, whilst apparatus acting on the transmitting or receiving device is controlled to give a constant amplitude output from the receiving device whereby the settings of this apparatus provides a measure of the relative efficiency of the device under test at different angular positions. The invention is described as applied to the determination of the polar diagrams of radio aerials, but is stated to be applicable to sound emitters. Fig. 1 shows apparatus for testing a transmitting aerial, the aerial being mounted for rotation about a vertical axis and energized from an oscillator through attenuators including a calibrating attenuator controlled by a servomotor system. The radiated waves are received by a stationary aerial situated some distance away, the output of which, after amplification and rectification, is compared with a D.C. reference voltage in a balancer circuit. The balancer output controls the attenuator servomotor system and any inequality between the received and reference voltages results in a variation of the transmitting aerial power until balance is achieved. In effect, as the aerial under test rotates, the received voltage is maintained constant by variation of the attenuator, the settings of which thereby indicate the aerial directivity. A drum recorder controlled in accordance with the attenuator settings and the aerial angular position produces a plot of the aerial field strength at different angles. Fig. 2 (not shown) illustrates apparatus for testing receiving aerials. The Specification discusses a number of auxiliary features including: the use of cathode-ray tube recorders; the elimination of noise from the receiving channel; methods of deriving the reference voltage from the oscillator to eliminate errors due to variation of oscillator power during a test; and a method of controlling the speed of aerial rotation in accordance with the rate of change of attenuator setting in order to plot the directivity curves slowly where the field strength changes rapidly and vice versa.
