Abstract: 112,591. McCaskell, J. A. July 30, 1917. Doors, lids, and covers.-Tanks or receptacles for filter-presses and other purposes are provided with means for operating the head fastenings and moving the head to and from the tank. Endless belts 21, Fig. 1, operated by a motor 28 carry a cross-bar 10, connected to the tank head A<1> by links 16, 17, Fig .3, and to a sleeve 2 movable on a shaft 1 carried by the head by a link system 7, 8, 9. In opening the tank, during the first part of the motion of the cross-bar 10, the links 16, 17 are straightened and the sleeve 2 is moved to disengage radial locking-bolts 3 ; the continued motion of the cross-bar then carries the head A<1> away from the tank. By reversing the motor, the head is moved back into contact with the tank at which time depending arms 19 on the links 17 come into contact with the stops 20, and force the links 16, 17 into the dotted line position of Fig. 3 as the cross-bar continues to travel so as to operate the locking-bolts 3. In a modification the belts pass around drums on a shaft H<1>, Fig. 5, which is connected by cranks and links to the sleeve controlling the locking-bolts and which is normally held from rotation by a pivoted catch 33<1> engaging a notch in a disk fast on the shaft and adapted to be disengaged by movement over a stop 20. In a further form, pins on moving chains engage notched arms on a shaft and rotate the shaft to withdraw the locking-bolts.

Abstract: 1,051,644. Automatic frequency control; radio signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 19, 1964 [March 22, 1963], Headings H3A and H4L. In colour television relaying by satellite, any Doppler frequency shift is corrected by variably delaying the received signal in accordance with any frequency error of the colour sync. burst signal derived therefrom relative to a frequency standard. The delay may be produced by a rotating magnetic storage drum, on which the signal is recorded and subsequently picked off, driven with variable speed by a motor controlled by a frequency discriminator, or by a phase discriminator with one input a local subcarrier frequency standard and the other the gated subcarrier burst signal. The standard frequency may alternatively be derived from the transmitter through a path, e.g. telephone line, not subject to Doppler effect. The discriminator output may alternatively control the circumferential angle between the record and pick-up heads of the drum, the speed of which is constant. Or the delay may be produced by supersonic oscillations passing through a fluid path of variable length. The recorded signal may be the colour subcarrier frequency, or an amplitude or frequency modulated carrier subsequently (i.e. after being delayed) demodulated to derive the colour subcarrier frequency burst.
