Filed: 1926-04-20
Abstract: 267,344. Minikin, R. R. April 20, 1926. No Patent granted (Sealing fee not paid). Jigs.-Raw material such as coal is fed into the jig by a shoot 1 and falls on a screen plate 2 where it is subjected to water pulsations. The denser and larger particles of impurities take up the lowest position and are drawn off through a gate 3 into the boot of an elevator 4. Less dense impurities forming a higher layer are withdrawn through a gate 5 and carried to the elevator by a conveyor 14. The coal mixed with small and light particles of impurity occupies the upper layer of the bed on the screen and the small particles of impurity pass through a vertical plate 6 provided with slits or perforations into a chamber 8 while the larger jigged product is flushed by the water over a cover plate 7 to a discharge outlet 11. The cover plate 7 may be perforated and may be slightly inclined. The smaller sized material collected in the chamber 8 is submitted to water pulsations on a screen 9, the coal passing off through the outlet 11 and the impurities being discharged through a gate 10 and shoot 12 to a conveyor 13.

Title: Process and apparatus for stabilizing the course angle of a ship
IPC: G05D1/02
Filed: 1974-03-11
Abstract: 1511137 Automatic control of course SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 11 March 1975 [11 March 1974] 10741/74 Heading G3N The course angle (angle with respect to North of a ship) is stabilized in respect of periodic deviations (line 12) about the desired angle 11 by applying a discrete rudder adjustment 15 when a peak of the periodic deviation has been detected, the rudder movement being in the same direction as the deviation to provide anticipatory control. A voltage proportional to the deviation is applied to a "hold" circuit comprising a capacitor connected through a diode, Fig. 3 (not shown). There is one such circuit for each direction of the deviation. The voltage on the capacitor is continuously compared with the deivation voltage; a difference indicates that the peak has been passed. This difference is applied to a threshold circuit so that when an amount 13 is reached a bi-stable circuit is switched to apply the rudder adjustment 15, which is to port when the deviation is to port but approaching starboard. This control is superimposed on that provided by manual or automatic pilot. The amount of rudder adjustment can be set differently for port and starboard. It is mentioned that the control may be effected using a digital computer.
