Title: Improved means for receiving frequency modulated signals
IPC: H04L27/148
Filed: 1963-08-13
Abstract: 1,010,199. Telegraphy. ALBISWERK ZURICH A.G. Aug. 13, 1963 [Aug. 15, 1962], No. 31897/63. Heading H4P. In an F.M. telegraph receiver the transition points between marks and spaces are determined with more accuracy than can be attained with a conventional discriminator by referring the approximate transitions from the latter to the modulating frequency. In one embodiment, the known discriminator comprises a limiter 11, filters 12, 13, rectifiers 14, 15 and low-pass filter 16. The D.C. pulses from filter 16 have sloping flanks so the transition points cannot be determined accurately. Unit 24 pulses at each of these points, positive-going transitions setting toggle 26 and negative-going transitions toggle 27. The pulses from filters 12, 13 are delayed at 21, 22 such that they are at a steady level at the time that unit 24 pulses. Transition detectors 23, 25 give a series of pulses of repetition frequency equal to the appropriate modulating frequency. These pulses reset toggles 26, 27. Thus a setting pulse-approximately timed-from 24 and the subsequent resetting pulse cause toggles 26, 27 to give brief pulses, which correspond more accurately to the correct transition times. These pulses feed toggle 28 which thus produces accurate Mark-Space signals. Other embodiments, being variants of Fig. 2, are described with reference to Figs. 3 and 4 (not shown). Reference is made to a system wherein the Mark-Space signals are derived from an infra-red position-indicating system.

A mechanically animated doll is designed to cradle or rock another doll, e.g. a baby doll, in its arms as shown in the figure. The body of the doll is divided at the waist into two parts a and b, which are axially pivoted by a shaft c which is rigidly secured to the lower trunk b. Inside the lower trunk b is housed a drive mechanism d provided with an output shaft e in the form of a crankpin. The end of the crankpin is introduced into a guide slot f formed in the base g of the upper trunk a. The drive mechanism d may be in the form of a musical box mechanism. The head h of the doll is pivoted so that it can rock on the top end of the shaft c. The head has a depending arm i which extends down from the head and terminates in a forked pin, one arm of which is indicated at j. A drive pin k is secured to the base g of the upper trunk q and is located between the arms of the forked pin. When the drive mechanism is started the crankpin e rotates and by sliding in guide slot f, causes the upper trunk a to oscillate relative to the lower trunk b about shaft c. The doll thus appears to rock the baby roll n that it holds in its arms from side to side. During this rotary movement, the drive pin k engaged between the arms of the forked pin oscillates from side to side about shaft c and this motion is transmitted by arm i to the dolls head which moves moves about its pivot on shaft c. The movement is a combination of nodding and shaking. The eyes e of the doll may be provided with a conventional mechanism to cause them to open and close when the head is pivoted.
