Abstract: ABSTRACT         A pressurized ink applicator for an intaglio printing press using stiff-bodied ink is provided with an ink-shearing element or heating element within the applicator nozzle to apply energy to the ink thereby to improve its flow properties immediately before its application to the printing plate of the press.  A tight seal between the nozzle and the printing plate is provided by spaced blades resiliently mounted in the nozzle.  Ink is forced by air pressure from an ink container into the nozzle.  Accumulating chambers are formed yin the flow path from the ink container to the nozzle immediately before constrictions in the ink flow path.  An optional sliding valve operating transversely in relation to the ink flow path controllably cuts off the flow of ink, as for example when gaps between printing plate edges pass by the nozzle.  The sliding valve is controlled by a cam moving with the printing plate.  The valve operates between gates having mutually offset openings so that ink flow pressure is borne by the gates rather than by the sliding valve.

Abstract: ABSTRACT OF THE DISCLOSURE        A stem in an alarm housing coaxially removably coupled to the lid of a coffee pot via a hole formed through the lid extends through the bore of a collar mounted in the housing and having a coaxial bore formed therethrough.  A spherical member is coaxially affixed to the stem at an intermediate point thereof and has a diameter greater than the diameter of the bore of the collar and rests in such bore whereby the stem is freely rockable in the collar.  A hollow shell is mounted on the stem at the upper end thereof and has a rattle member encased therein which produces an alarm sound whenever it strikes the shell.  An actuating member is mounted on the stem at the lower end thereof and is positioned in close proximity with the top of the per-forated tube of the coffee pot.  Thus, when the coffee perks, water flows into the top of the tube of the coffee pot and strikes the actuating member to produce an oscillatory motion of the stem about the spherical member thereof.  This causes the rattle member to strike the shell to produce a series of alarm sounds.

Abstract: ABSTRACT     Tractor-drawn agricultural mower has three crop-cutting rotors rotatable about vertical axes and carrying crop-feeding drums.  Two of the rotors contra-rotate inwards to feed cut crop between them.  The third rotor is offset rearwards from a straight line intersecting the axes of rotation of the other two rotors and rotates in the same direction as the rotor adjacent it so that the crop which it cuts passes behind the adjacent rotor and towards the crop which has passed between the other two rotors, whereby a single swath of crop is produced by the mower.

Abstract: VELOCITY ERROR CONTROL APPARATUS     ABSTRACT OF THE DISCLOSURE     Velocity error control apparatus for use in a video signal time base corrector of the type including a main memory having addressable storage locations for storing successive lines of video signals, write-in circuitry including a write-in clock signal generator synchronized with time base errors in the video signal for writing successive lines of video signals into addressed storage locations at a write-in clock signal rate, and read-out circuitry including a controllable read-out clock signal generator for reading out successive lines of video signals from addressed storage locations at a substantially constant read-out clock rate.  The velocity error control apparatus includes a velocity error detector for detecting velocity errors in successive lines of the video signals which are written into the main memory.          A velocity error store has a plurality of storage locations, each being operative to store a velocity error signal representing the velocity error of an associated line of video signals, and a velocity error read-out circuit reads out the velocity error signal from the velocity error store, which velocity error signal is associated with a line of video signals when the associated line of video signals is read out from the main memory.  A modifying circuit modifies the read out velocity error signal as a function of at least one velocity error signal which is associated with at least one adjacent line of video signals.  The modified velocity error signal is used to modulate the read-out clock signals so as to compensate for the velocity errors in successive lines of video signals.                             -i-

Abstract: MATERIAL HANDLING APPARATUS                            ABSTRACT         Apparatus is provided for depositing material, such as mushroom casing, on a horizontally moving belt from which the material is discharged to a surface beneath said  belt. The material may be deposited first in a conveyor box which contains an element capable of moving the material in the box from one end of it to its other end, the said conveyor box having an outlet through which the material is passed to a distributing container. If preferred, the material may be deposited directly in the distributing box. This container also has in it means for moving the material from one of its ends to the other, a desired, in order to achieve a sub-stantially uniform distribution in it of the material. The container has in it an outlet which comprises a slot of uniform gap. This gap is located in a position to be in delivery relationship with said moving belt. The gap is formed through the use of a cut-off plate that may be constructed of adjustable section. The container also is equipped with a means to discharge the material through said gap onto said belt to form a layer thereon that is sub-stantially uniform in its width end thickness. The dis-charging means used in getting a uniform layer comprises, in the main, the moving belt but the means for moving the material in the distributing box participate in the effective discharge.  One end of the belt is fixed to a roller on which most of the belt is wound. The other end is fixed to a platform near and underneath the distributing box. As the belt moves forward horizontally, it is in effect unwinding, and the material on it falls off at the reversal point of the belt onto a surface, usually a prepared bed of compost.
