Title: Circuit arrangement for suppressing one side band in an amplitude modulated broadcast transmitter by means of an additional phase modulator
IPC: H03C1/60
Filed: 1959-04-10
Abstract: 877,832. Amplitude modulating systems. TESLA, NARODNI PODNIK. April 10, 1959 [April 12, 1958], No. 12187/59. Class 40(5) In an amplitude modulation transmitter, the output of the carrier frequency oscillator 1 is phase modulated at 5 prior to being amplitude modulated at 3, a feedback loop from the transmitter output to the phase modulator 5 controlling the phase modulation of the carrier so that one side-band is suppressed. The feedback loop comprises mixers 7, 11 and band-pass filter 8. Mixer 7 is supplied with the amplitude modulated output of the transmitter and the output of oscillator 6 having a frequency below the carrier frequency, e.g. 10 kc./s. less. The output of mixer 7 is thus the transmitter output transferred to a 10 kc./s. carrier, filter 8 passing the sideband to be suppressed. Mixer 9 is fed by oscillators 1, 6 and has an unmodulated output at a frequency of 10 kc./s. which is fed to mixer 11 over phase shifting network 10. Filter 8 may select only a part of the sideband so that, for example, the lower modulating frequencies are transmitted on both sidebands and the higher frequencies on one sideband only. The feedback voltage to phase modulator 5 may be combined with the input modulating signal passed through a phase shifter 12.
Patent GB-179198-A (GB)
IPC: C05F3/00
Filed: 1922-05-01
Abstract: 179,198. Krantz, F., Krantz, H., and Krantz, H. May 2, 1921, [Convention date]. Manures. - Farmyard manure or other organic material suitable for use as manure is arranged in heaps, loosely stratified to allow of an adequate supply of air for fermentation. Dry organic matter such as potato peelings, chaff, weeds or thick-stemmed plants are added to a very moist manure or liquids to a dry one. After temperatures of 30 to 65‹ C. have been reached, the fermentation is stopped by trampling on the mass or subjecting it to pressure, either mechanically or by the superposition of more manure. Shields, Fig. 1, or grates, Fig. 2, are placed in the heaps to prevent excessive pressure on the lower layers. The heaps may be rectangular or wedge-shaped. When a row of wedge-shaped heaps is arranged as shown in Fig. 4, manure may be subsequently filled into the spaces between the heaps. A grate may be placed under the material so that air has easier access and liquid can drain away. This liquid may be mixed with peat dust and the product used as a top dressing. A light or supported protective covering may be provided on the top or on the sides of the heaps.

Filed: 1930-04-22
Abstract: 576,714. Hydraulic machines. MILES, J. April 22, 1930, No. 12382. [Class 69 (ii)] [Also in Group XXVIII] A linear relation is established between the position of a movable part such as a handle or index and the speed of a moving part such as the fore-sight of a bomb-sight by using the movable part to vary the pressure gradient along a capilliary tube 4 or other passage through which fluid is supplied to a piston and cylinder or equivalent connected to the moving part. As shown, the handle 6 actuates a spring-controlled valve 5 controlling the supply from a source 13, through a temperature-compensating gearing 7 comprising a helical cam the axis of which is laterally adjustable, and at the same time actuates a contact &c. in correlation with the piston, through gearing 8. In a modification, the passage 4 is bimetallically constructed to maintain a constant relation between pressure gradient and flow. An auxiliary valve 3 or a connected variable volume allows the piston &c. to be retarded or controlled. The piston may move against gravity or against fluid supplied through a pipe 9. A counterweight 11 on a fixed pivot may prevent disturbance due to accelerating.

Abstract: 651,149. Aircraft undercarriages. SOC. D'INVENTIONS AERONAUTIQUES ET MECHANIQUES, S.I.A.M. May 5, 1948, No. 12435. Convention date, May 6, 1947. [Class 4] A retractable undercarriage comprises tandem landing wheels carried by a bogie pivoted to the lower end of the undercarriage leg, mechanism being provided to rotate the bogie relatively to the leg during retraction, so that the bogie remains in a substantially horizontal attitude during the first portion of retraction, after which it is rotated about an axis extending longitudinally of the leg so as to bring the plane of the wheels parallel to the under surface of the wing. In the construction shown the wheels 5, 6 are mounted on a bogie 4 pivoted at 3 to the plunger 2 of the undercarriage leg, which is suspended from the air frame by a link 8 and is actuated by a jack 19 acting on a folding strut 15. The pivot pin 9 between the top of the undercarriage and the link 8 carries a crank-arm 23 connected to an extensible rod 24, 25, the lower end of which is connected at 27 to the bogie 4, to maintain. the latter in a substantially horizontal attitude during retraction. As the undercarriage approaches the fully raised position it is rotated through a right angle about the longitudinal axis a-a of the leg, into the housed position shown in Fig. 5. A cam mechanism Fig. 6, for effecting such rotation, comprises a cam slot 48a, 48b engaged by a roller 47 carried by a member 45 mounted on a pivot 46, and attached by a tie-rod 42 to one of a pair of links 36, 37, the former of which is pivotally connected to a member 41. integral with an internal tube 32 of the undercarriage. The portion 48a of the cam slot is concentric with the axis of the pivot member 9, so that no movement of the links 36, 37 occurs while the roller 47 engages the slot 48a. When it engages the divergent portion 48b, rotation of the member 45 takes place about the pivot 46 and the tie-rod 42 operates the links 36, 37 to cause rotation of the undercarriage about the axis a-a.
