Title: Improvements in or relating to pulse-modulation multiplex communication systems
IPC: H04J3/04
Filed: 1955-09-30
Abstract: 778,895. Pulse modulation. DAYONNET, F. J. D., and PINET, A. E. Sept. 30, 1955 [Dec. 3, 1954], No. 27911/55. Class 40(5) In a pulse phase modulated time division multiplex system, each of the channel pulses consists of a negative pulse, followed immediately by a positive pulse, and the synchronizing pulses consist of a positive pulse followed by a negative. At the transmitter, Fig. 1 the output of pulse phase modulators 2<SP>1</SP>...n are selected in sequence by gating pulses obtained from a master generator 3 and tapped delay line. The modulators are stated to be of the type in which a saw-tooth wave is variably dipped in accordance with the modulation. Negative, modulated pulses are inverted by an amplifier 7 to provide the output 10, the pulse train shown in Fig. 3(b). Synchronizing pulses from the generator 3 are provided uninverted, Fig. 3(a), by the cathode-follower 5. A shortcircuited delay line 9 is also connected to the output 10 to add the delayed, inverted pulses, Fig. 3(c) that characterize the invention. At the receiver, Fig. 2 (not shown) the incoming signals, Fig. 3(c) are applied to a short-cicuited delay line which adds the delayed inverted pulses, Fig. 3(d) to the original to provide the waveform of Fig. 3(e). The synchronizing pulses are selected by clipping above the line 33 and the signal pulses are selected by inverting the wave train, Fig. 3(f), and clipping above the line 34.

Abstract: 480,190. Coin - freed article delivery apparatus. UNIVERSAL AUTOMATIC DELIVERY CO., Ltd., and PEARSE, W. Oct. 15, 1936, No. 28017. [Class 27] Coin action, thrust and weight.-Cigarettes or like rod - shaped articles are displaced along an inclined shelf k, by a circular following weight l towards a delivery plunger g which is first depressed to receive the foremost article and then raised to deliver that article upwardly through an aperture a<1>. A coin, as it is being thrust in through a slot c to a shoot c<1>, rocks a short lever d connected by a rod e to a lever f which is thereby rocked against the action of a spring f<2> to depress the plunger g. The lever f is retained in this position by a shoulder h<1 >on a spring-pressed detent h, until the coin dropping down the shoot c<1> engages a lever j which it moves downwardly so that an arm i connected therewith trips the detent to allow the plunger to rise and deliver the article resting on it. Coin-slit closing-devices.-The weight l rolls along a shelf m pivoted to rock through a small angle by being attached along one longitudinal edge to a rod n pivoted to the shelf k. When the last article is delivered, the weight l drops off the shelf m so that it can rock under the action of a spring n<1> thereby causing the upper end of the rod n to obstruct the coin slit c.
