An auger 2 may be used to mix the contents of vessel 1. Feed unit 7 may be an auger feed unit, and liquid supply unit 8 may be a pump. Operation. When the level of liquid in vessel 1 falls below the lower tip of the sensor, relay 10 is actuated and timer 11 energised to operate pump 8 for a pre-set time. At the end of this time interval, an output signal from timer 11 triggers timer 12 to operate feed unit 7 for a pre-set time. At the end of this operation, an output signal from timer 12 is fed via line 12b to reset relay 10 and to actuate a selector and switching unit 13, which in association with uniselector 14 and solenoids (not shown), exercises a controlling function in the operation of valves 6a-6n, which control the supply of foodstuff to the feeding points. According to a modification, valves 6a-6n may be manually controlled provided that an indicator or indicators showing the number of cycles of operation of the relay is or are visible from the valve positions so that the operator can determine the period the valves have to remain open for the supply of predetermined increments of foodstuff.

Abstract: 567,969. Warfare, teaching. TECHNICOLOR, Ltd., GUNN, F. G., and HAGUE, E. Dec. 10, 1941, Nos. 15948/41 and 15517/42. [Class 119] In gunnery, bomb-dropping or analogous aim-teaching apparatus, the flight or bursting of projectiles is simulated by the projection on to models or on to a screen k, by means of a lens h, of spots of light released by creating perforations in one or more illuminated opaque diaphragms a,a<1>, by means of a perforating apparatus which is moved in accordance with that part of the aiming apparatus representing the gun or bomb sight. The (paper) diaphragms a, a<1>, are mounted on a frame b fixed to a spindle c<1> mounted in a stand c, and their convex surfaces are illuminated by a lamp-and-condenser system g. When the firing trigger (not shown) on the gun sight mounting d is pressed, an electrically-driven cam (not shown) moves a pivoted needle - bearing frame m from the dotted-line position through the arc o to the full-line position, then an electrically-driven spindle t revolves and, via eccentric s lever q and link p, thrusts the needle l through the diaphragms. The needle may be thrust through four times in a second.. The needle is withdrawn, the frame m descends, and light shines through the perforations made by the needle, through the lens h and on to the screen. The lens h is so mounted on a gimbal j, j<1> that it can pivot in any direction about its nodal point. The gun sight mounting d is fixed to the gimbal component j<1>. To simulate the effect of tracer projectiles disappearing in the distance, the diaphragms may be moved relatively to one another so that the perforations do not coincide, the emerging light beam being gradually cut off ; thus, the inner diaphragm a<1> has a circular rack 2 rotated by a pinion 3 from a small motor. To simulate the effect of gravity on a tracer projectile, a part or whole of the device may be tilted so that the spots of light seem to fall during their time of flight.
