Title: Ejector mechanism for printing machines
IPC: B41L47/24
Filed: 1920-05-14
Abstract: 143,264. Addressograph, Ltd., (Assignees of Duncan, J. S.). Aug. 14, 1916, [Convention date]. Addressing - machines; platen machines. - Printed envelopes, tags, &c. are delivered from addressing and like machines bv means of an ejector actuated by a lever adapted to be engaged momentarily with an oscillating or reciprocating part of the machine, and to be returned to rest by a spring. As applied to a machine, shown in plan in Fig. 1, in which printing-plates are fed from a magazine 7 to beneath a ribbon 6 and the envelopes &c. are printed by an impression member 9 operated by a handle 11, the envelopes are registered against an adjustable guide-bar 12, and against the edge 16 of the ejector which is carried by a rod 17, connected by a clamping-screw 19 to an oscillating lever 18. An extension 26 on this lever is acted on by a spring 28 which keeps the pusher normally in the position shown, and acts to return it to this position after it has been operated to eject the printed envelope. This movement is effected by a tripper 31 secured by a screw 33 to the impression member, the tripper 31 being formed with a bevelled edge 31', Fig. 3, which on the downward movement snaps past a similar edge 34<1>, on pivoted arm 34 carried by an extension 27 of the pivot of the lever 18, and normally kept in the position shown by a spring 36. On the return movement of the impression member the tripper 31 engages the bevelled edge 34' of the bar 34, and the lever 18 is actuated to cause the ejector 16 to deliver the envelope which is guided by the bar 12 during delivery. A screw 37 may be set so as to lower the arm 34 against the action of spring 36, so as to render the ejector mechanism inoperative.

Abstract: 1465925 Radar LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 26 March 1974 [2 April 1973] 13447/74 Heading H4D A compact CW Doppler radar, employs a high efficiency transistor microwave oscillator 10 to produce CW oscillations at a frequency fo and a diode 13 having a reverse voltage dependant capacitance acting as (a) a frequency multiplier for the output of the microwave oscillator, such that CW oscillations of frequency nfo are fed to the transmit/receive aerial, and (b) a mixer for mixing the received echo oscillations of frequency nfo+Sf, possibly Doppler frequency shifted by amount Sf, with a small part of the frequency multiplied oscillation to give Doppler frequency oscillations of frequency Sf for a low pass Doppler filter 16. The use of a transistor microwave oscillator and a separate diode frequency multiplier/ mixer, as against a common function Gunn effect element, is said to yield higher efficiency and longer life. The output of the transistor oscillator (a single transistor with a tuned base, Fig. 4 (not shown)), is fed across the diode (which may be a Schottky diode, on a point contact diode) via a transformer 11 and a narrow band rejection filter 12 antiresonant at nfo. The output component of diode 13 at nfo is fed to the aerial via a rejection filter 14, antiresonant at fo and a transformer 15. The Doppler beat frequency Sf is fed from the diode to the utilizing circuit via filter 12, Doppler filter 16 and transformer 17. A practical stripline embodiment of the circuit of Fig. 2 is given in detail (Fig. 3, not shown). The output of the transistor oscillator 10 may be 80 mw. at 5GH 3  and the output of the diode may be 30 mw. at 10GH 3 .

Title: Electronic apparatus utilizing a cathode ray tube
IPC: H03B21/00
Filed: 1957-04-29
Abstract: 856,018. Cathode-ray tubes. RYDBECK, O. E. H., and STENHARDT, C. M. E. April 29, 1957 [May 2, 1956], No. 13550/57. Class 39(1). In a cathode-ray tube apparatus for obtaining frequency addition or subtraction the beam is deflected in a closed preferably circular path at frequency f, and auxiliary radial deflecting fields are superposed on the closed path by electrodes Hnm and an electrode S 8 , the electrodes Hnm being divided into interleaved groups each with n electrodes a source of multiphase energy, such as a second cathode-ray tube, of frequency f 2  and m phases each phase being connected to a different group of deflection electrodes Hnm to produce the auxiliary radial deflecting fields having m phases and n polepairs, the auxiliary deflection field rotating at a frequency of f 2 /n the output frequency being nf 1   # 2 , depending on the relative directions of the beam sweep and rotating field. In Fig. 2 the target comprises a plate S 8  and a plurality of plates Hnm arranged in annular formation which are energised by a six phase supply to produce a rotating electric field which deflects the beam locally on and off the plates S 8  and Hnm. The beam thus oscillates radially, e.g. under the control of 3 volts D.C. and a superposed 3 volts A.C., so that it strikes S 8  or passes through to collector S 10  but does not strike plates Hnm at all. The multiphase waveform applied to plates Hnm is generated by an auxiliary cathode-ray tube 151 in which the beam rotates over target sectors P 1  . . . Pm equal in number to the number of phases to be generated, and is applied to the electrodes Hnm of tube 150 via amplifiers F and condensers C 21 , C 22 , while the D.C. bias is applied to plates Hnm via resistances Rm from source 55-56. A reversing switch Sw enables the direction of rotation   of the beam to be reversed. w 2 /2#n = frequency of rotation of multiphase field in tube 150, and the beam rotates at a frequency  w 1 /2# in main   tube 150, then if w 2 /2#n nequals w 1 /2# and beam and field rotate in same direction there is anly a constant D.C. output. If they are not equal then the output has a frequency n(f 1   f 2 /n) according as to whether the directions of rotation are opposite or the same. The device of Fig. 2 can be regarded as a device for shifting the output carrier frequency nf 1  of a conventional frequency multiplier tube to nf 1   f 2  according to the position of switch Sw.
