Abstract: The invention provides an improved method and apparatus for separating fruits, such as tomatoes, from vines. The invention uses feeder bars to provide tomatoes to a shaker brush a first time. The vines are allowed to fall out of the shaker brush to a shaker conveyor. The shaker conveyor conveys the vines into the shaker brush a second time, and then to a vine reel, thus providing an improved separation of tomatoes from the vine.

Abstract: The present invention provides a method for preparing a spray-dried compressible granular formulation for preparing pharmaceutical tablets in which hydrolyzed cellulose is used as a granulation aid, the resulting granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1 to 97% by weight pharmaceutical active, from about 3 to 99% by weight hydrolyzed cellulose, based on the dry weight of the granulation, and optionally conventional granulation and/or tableting additives such as surfactants, disintegrants and antiadherents/flow aids.

Abstract: The microetching and cleaning of copper clad substrates in printed wiring board production with solutions containing alkali metal persulfate and sulfuric acid is controlled to provide slower and more consistent copper etch rates by the presence of high proportions of alkali metal sulfate or an alkali metal sulfate/bisulfate mixture in the solutions, in a mole ratio of persulfate to sulfate or sulfate/bisulfate mixture of 1:0.1 to 1:10. When bisulfate is present with the sulfate, the sulfate will comprise at least about 10 mole % of the sulfate/bisulfate mixture. A surfactant may be present in the solutions to aid wettability on the copper clad substrates.

Abstract: There is provided a differential motion conveyor comprising a trough and a conveyor drive. The conveyor drive comprises a clutch/brake assembly which is selectively activated for moving the trough at a first speed in a first direction and selectively deactivated when moving the trough at a second speed in an opposite direction. There is further provided a method of conveying material comprising sensing a position of a trough, activating a clutch/brake assembly when the trough is at a first position for moving the trough at a first speed in a first direction, and deactivating a clutch/brake assembly when the trough is at a second position for moving the trough at a second faster speed in a second opposite direction to the first direction.

Abstract: Polyalkenylaromatic-polyethylene copolymers are prepared using protected functional organolithium initiators. Polymerization of an alkenylsubstituted aromatic monomer followed by ethylene, results in a protected functional block polystyrene-co-polyethylenyllithium. Termination with a functionalizing agent followed by deprotection produces polymeric products with high functionalization at the initiating chain-end and at least partial functionalization at the terminal chain-end.

Abstract: An alkali metal peroxydisulfate or caroate can be used alone or in combination to destroy haloform present in an aqueous system. The destruction results in a reduction in the amount of haloform in the system. In another aspect, uv light and the peroxydisulfate and/or caroate can be used together to destroy the haloform present in the aqueous system.

Abstract: An apparatus and process for coating food products with seasoning, powder or other dry or granulated material while the food products are rotated in a drum uses a trough which extends into the drum from outside of the drum. The trough provides a plurality of V-shaped channels having intermittently arranged lengthwise slots along low points of the channels for creating curtains of material falling through the slots onto the food products. The trough is vibrated for inducing flow along its length as well as for preventing clogging of material flowing through the slots. Alternately the material can spill over a tapered wall of the trough rather than through slots. A vibrating inlet feeder which provides a screening surface is located upstream of the trough for screening the material before discharge into the trough and eventual discharge into the drum. A controlled screw feeder can be used to limit and regulate flow of material into the inlet feeder.

Abstract: The invention provides a harvester that applies continuous contact between the plant to be harvested and harvesting rails, which thus reduces damage to the plant. The harvester uses a hydraulic system which causes the rails to provide a constant gripping force against the plants when in a float position of the hydraulic system. The system also has a spread setting and may or may not have a third static setting.

Abstract: A pig delivery and transport system shown schematically in FIG. 1 has a looped line generally indicated at (10) divided into three sections (10A), (10B) and (10C). Line section (10A) is a low pressure non-product line section extending from a product receiving facility (PF) or host to an upstream shut-off valve (20). Line section (10B) is a high pressure product line section extending from downstream shut-off valve (22) to host facility (PF) and receives product from wells (W1) and (W2). Intermediate line section (10C) is a connecting line section between shut-off valves (20) and (22) to connect the non-product line section (10A) to the product line section (10B). A pig inserted at host (PF) is transported along low pressure non-product line section (10A) into connecting line section (10C) while upstream shut-off valve (20) is open and vent valve (28) is open in vent line 26.

Abstract: This invention pertains to sensorless measurement of electromagnetically induced displacement in actuators and similar units. Primarily, the device imposes a constant frequency and amplitude excitation sine wave on a coil through a fixed impedance of a drive isolation network. The amplitude and phase of the voltage across the coil fluctuate depending upon the coil's inductance. This variation in the value of the inductance is dependent upon the change in magnetic flux density generated by the coil current and the displacement in air gap between the coil pole and armature. Accordingly, a measurable magnitude of displacement can be controllably imposed upon a system of solenoids. The displacement is thus measured and set without the use of extrinsic sensors.
