Title: A device for receiving and re-transmitting impulses particulary for telephonic line systems
IPC: H04Q1/442
Filed: 1946-04-25
Abstract: 616,297. Impulse repeaters. COMPAGNIE GENERALE D'ELECTRICITE. April 25, 1946, No. 12535. Convention date, June 2, 1944. [Class 40 (iv)] An impulse receiving relay circuit normally has a high impedance so as not to shunt voice currents, but at the onset of each impulse is caused to have a low impedance so as to absorb incoming line discharges which would otherwise tend to prolong the repeated impulse. As shown, the crest shearing networks El, E2 are normally connected in series with the rectifier network R supplying the impulse receiving relay 2, so presenting a high impedance to the line A, B. On the arrival of an impulse sufficiently large to operate 2, the follower relay 1 connects R directly across the line 'with E1 in parallel, thereby lowering the impedance presented to the line. The Specification as open to inspection under Sect. 91 describes an arrangement wherein the impulse relay is energized over a transformer, a third coil of which is connected to a gas-filled diode which fires and so lowers its impedance at the onset of each impulse. This subject-matter does not appear in the Specification as accepted.

Title: An improved coin-operated vending machine

Filed: 1940-08-05
Abstract: 543,028. Coin-freed article-delivering apparatus. GARRETT & CO., Ltd., ;C., and WEST, L. Aug. 5, 1940. No. 12576. [Class 27] A machine for vending and dispensing substantially cylindrical articles or packages comprises a supply compartment or hopper from which delivery is effected on insertion of a coin, an agitator for agitating the articles in said compartment to facilitate delivery, a trough-like delivery member for receiving the articles from said compartment and coin-operated means for moving the agitator and rocking said delivery member between positions in which it respectively receives and delivers an article. In the construction shown arranged to deliver one cigarette 11 from a hopper 10 each time a coin is inserted the outlet 12 from the hopper is formed by a fixed front plate 12b and a vertically-movable back plate or agitator 14 having a corrugated part 13 extending upwardly into the hopper. A vertically-movable control plate 17 rests by means of a buffer 19 on the front plate 12b. The lowermost cigarette rests, as shown in Fig. 3, in the hopper outlet on the edge of a discharge trough 20 mounted on a shaft 21 which carries an arm 32 having a pin 33 adapted to engage a catch lever 34 pivoted at 35. When a coin is inserted in the machine is passes over and depresses a plunger 23 which rocks a lever 24 and raises a spring-loaded slide 17c carrying the control plate 17 so that this is raised to the position shown in Fig. 6 and leaves the lowest cigarette supported only by the trough 2v. The coin next passes over a stop 26 and raises a lever 27 which acts through another lever 28 to lift the back plates 13, 14 until a rubber strip 31 on 14 engages the trough 20 and tilts it to the position shown in Fig. X5 in which it receives the lowest cigarette, the trough being held in this position by a catch 36 on lever 34 engaging the pin 33. As the coin passes on to a vertical shoot it releases the lever 27 and the back plate 13, 14 is pulled down to its original position by a spring 29, the upward and downward movements of the plate agitating the cigarettes in the hopper and preventing them from jamming. The coin in dropping down the shoot 39 to the till 42 strikes the tail 34a of lever 34 so that pin 33 is released and a spring 38 rocks the trough 20 to discharge the cigarette resting thereon, the trough being again in the normal position shown in Fig. 3. The machine is enclosed in a locked casing, not shown, and is preferably mounted on a wall so as to tilt forwards about 15 degrees. In a modification the catch 36 may be released by a push-button or the like instead of by the coin. Coin-testing apparatus may be included in the machine.

Abstract: 886,357. Measuring magnetic fields; transistors. TESLA, NARODNI PODNIK. April 15, 1959, No. 12786/59. Drawings to Specification. Class 37. A junction transistor is used to measure a magnetic field by placing the transistor with the emitter-collector current path at an angle of from 0 to 30 degrees to the direction of the field, the transistor being in common emitter or collector configuration and the variation in the current change in the collector-emitter circuit being a measure of change in the magnetic field. The transistor circuit is preferably constructed with no connection made to the base. Characteristic curves, Fig. 1, not shown, illustrate that the collector-emitter current flow changes at any given value of base current in dependence upon the value of the magnetic field and its direction. It is stated that the collector-emitter current changes linearly with respect to the magnetic field strength, Fig. 3 (not shown). The collector-emitter current flow in the transistor may be amplified in a further transistor stage. PNP or NPN junction transistors may be used.

Abstract: 575,991. Photographic light-sensitive emulsions. KODAK, Ltd., DAVEY, E. P., and SELWYN, E. W. H. Aug. 10, 1943, No. 12921. Drawings to Specification. [Class 98 (ii)] The variation in gamma given by a lightsensitive silver halide emulsion layer in the range 280 (or even 250) mÁ to 400 mÁ is reduced by incorporating diffusely in the emulsion (preferably prior to coating) a substance other than a cyanine, hemicyanine or merocyanine, absorbing at every wavelength over the range 400 to 350 mÁ and whose maximum absorption within that range is greater than the absorption (if any) at every wavelength over the range 350 to 280 mÁ (or preferably to 250 mÁ). Substances specified are m-nitraniline and pnitraniline. Formulµ are given for the desired light absorption of the substance and for a developer to be used when measuring the gamma. A yellow dye, e.g. tartrazine, naphthol yellow, or auramine, which absorbs relatively strongly between 400 and 500 mÁ and relatively weakly between 280 and 330 mÁ, may also be incorporated to reduce the gamma between the wavelengths 450 to 500 mÁ. In example 1, to three portions of a silver iodobromide emulsion are added (a) no addition, (b) p-nitraniline (or p-nitraniline hydrochloride), and (c) p-nitraniline (or p-nitraniline hydrochloride) and tartrazine. Curves are given for these three portions of gamma plotted against wavelength. The pH of the emulsion is preferably 6.5 or less. In example 2, a solution made by adding an ethyl alcohol solution of p-nitraniline to aqueous hydrochloric acid is added to a silver bromide emulsion of pH 6.5. In example 3, an ethyl alcohol solution of mnitraniline is added to a silver bromide emulsion of pH 7.0.
