Title: Character indicator with means for monitoring the correct positioning of the character carrier
Inventor: PIAZZA GIAN-FRANCO
IPC: G09F11/06
Filed: 1970-02-09
Abstract: 1284983 Electric selective signalling AUTOPHON AG 9 Feb 1970 6153/70 Heading G4H A character indicator system comprises a character carrier in the form of sheets 10 which co-operate in pairs to display a series of characters, a motor 1-3 energized by an A.C. source connected to terminals 19 to drive the carrier, and a plate 16 driven by the motor, the plate controlling an alternating current generator to supply a carrier position monitoring signal to the terminals 19 and the alternating current generator signal having a frequency which is at least double the frequency of the source driving the motor. The shaft 15 is rotated one half a revolution by each positive and negative pulse applied to the terminals 19, this shaft rotation being transmitted by gears to the character carrier to successively change the character indication. The plate 16, which may be a non- magnetic conductor, alternately enters or is displaced from the gap 13 in the core 14 of the alternating current generator which includes a transistor 17 fed by a rectifier 20 supplied from the motor driving source. An alternating current signal is therefore fed to a coil 22 and induces the carrier position monitoring signal in the coil 1, this signal being transmitted along the motor supply lines. In modifications, the plate 16 comprises the moving vane of a condenser connected to the alternating current generator or an eccentrically mounted magnet mounted on the plate co-operates with a resistor, the value of which is dependent on the magnetic field and controls the frequency of or switches on and off the alternating current generator. In a further modification the monitoring signal is provided by an alternating current source switched on and off by a magnetically operated switch controlled by the plate 16. A binary cooled magnetic disc driven by the motor and co-operating with five magnetic field sensitive resistors connected to five alternating current generators each having a different frequency is also described for directly determining the position of the character carrier.

Title: Improvements in or relating to radio telegraph receiving arrangements
IPC: H04L27/08
Filed: 1942-05-08
Abstract: 557,225. Automatic volume controL CREED & CO., Ltd., and MASON, F. P. May 8, 1942, No. 6225. [Class 40 (v)] A telegraph receiver is provided with an automatic volume control which is adjusted in the appropriate upward or downward sense during a marking period and maintained as adjusted during the succeeding spacing period. During a marking signal, voltages derived by rectification from secondaries 7, 8 render valves 14, 15 conductive, and so allow a negative voltage proportional to signal strength derived from secondary 9 by rectification to be fed from the lower end of resistance 13 through valves 14, 15 to the ungrounded electrode of condenser 22 which is also connected to the A.V.C. line of the receiver 1. During a space, valves 14, 15 become non- conducting leaving condenser 22 isolated, so to maintain the A.V.C. at its adjusted value during the space. The value is readjusted at each marking signal. A high resistance 23 is provided to allow slow discharge of condenser 22 to meet the case of severe and sudden fading during a space such that valves 14, 15 are not energized during subsequent marks, the condenser having no opportunity of readjustment until the signal regains its value. A potentiometer 24 allows the sensitivity of the set to be adjusted to prevent the receiving apparatus 4 being operated by the noise during spaces.

Abstract: 286,256. Gleason Works, (Assignees of Wildhaber, E.). March 1, 1927, [Convention date]. Addition to 284,718. Gear-cutting; milling-cutters.-In skew gearing, the tooth surfaces of each member of a pair are produced by moving a planing, milling, grinding, or lapping tool across the face of a tapered gear blank in a curved or straight path inclined to a straight generatrix of the pitch surface of the blank, while rotating the blank on its axis and simultaneously producing an additional relative movement between the tool and blank about an axis offset from the blank axis. As described, the offset axis 36 is that of a basic crown wheel 35 with teeth formed longitudinally either curved, preferably in circular arc form, or straight, preferably with plane surfaces, the milling-tool 34, for example, representing its teeth and the pitch plane 37 of the wheel, shown at 60, Fig. 2, being tangent to the conical pitch surfaces of the gear members 10, 11 and passing through their theoretical point of contact 62. The crown wheels represented by the tools are of different diameters for the two gear wheels, but have teeth inclined at the same angle to their radii. The tool 34 carries two blades which cut opposite side faces of a tooth successively, or each blade may have a pair of cutting-edges forming two adjacent faces simultaneously. Fig. 3 shows the wheels 10, 11, the plane of the paper being that of the pitch planes of the basic crown wheels. The curved or straight line 72 of the tooth passes through the point of contact 62, through which pass also the projections 13<1>, 14' of the gear and pinion axes and the line 67 passing through the centres 65, 66 of the basic wheels for the gear and pinion, respectively. Geometric constructions and mathematical formulµ are included in the Specification for determining the distances 62-65 and 62-66 and the angle h' between the line 67 and the tangent to the tooth at the point 62. Teeth corresponding to curved teeth on the basic, wheels may be cut by a milling-cutter with cutting-edges of circular arc profile, or may be cut of constant depth by a straight-sided or conical cutter. Planing-tools. moving across the blank faces on curved paths, or, for straight teeth on the basic wheels, in straight paths, may be used. Curved teeth may be produced in a hobbing or continuous indexing process employing a face mill or a worm hob or a pair of planing-tools moving in straight paths across the continuously rotating blank. Specifications 199,462, 263,798, and 270,669 are referred to.
