Abstract: Comminuted wood is converted to a colored wood product useful as a mulch by feeding the comminuted wood into the lower end of an angularly upward positioned screw conveyor having an internal auger. The comminuted wood is contacted in a basin in the lower end of the conveyor by a liquid color-imparting agent, preferably an aqueous solution containing iron oxide pigment, carbon black pigment or a mixture of both pigments. After contacting, rotation of the auger draws the moist colored wood product towards the upper end, permitting runoff of excess liquid agent, which returns by gravity to the basin for further contacting with newly-fed comminuted wood. The liquid level in the basin is monitored and additional liquid agent is blended from water and pigment concentrate to maintain the level in the basin. Colored wood product discharges through a chute at the upper end of the conveyor for further drying, if necessary.

The cams then release the fingers so they engage the work piece in spring-loaded gripping relation. The wheel carries work pieces from the pickup point, down into the electrocoating solution and then to a rinse conveyor.

Abstract: A barrier assembly for a Langmuir trough is arranged for a substrate to be carried automatically to-and-fro on a dipping head over a fixed barrier into monomolecular layers A, B on a common subphase so as to stack layers ABABAB . . . on the substrate. The layers A, B are confined by the barrier and two constant perimeter areas formed by a single flexible band passing over rollers. By adjusting the positions of bridges that carry some of the rollers, the confined areas can be contracted to compress the layers A, B. In an alternative mode the substrate receives a layer from layer A while a new layer B is being formed, the substrate then being transferred to layer B while a new layer A is being formed. This involves an oscillating rather than a rotating movement of the substrate.

Abstract: For HgCdTe liquid phase epitaxy (LPE), in situ differential thermal analysis apparatus is used to precisely monitor the liquidus temperature of each HgCdTe melt. The neutral body, e.g. a slug of copper enclosed in a silica ampoule, is placed near the LPE reactor in a furnace. During heating or cooling, differential sensing of a pair of thermocouples (in the melt and in the neutral body) will show an accelerated change at transformation points, since at these points the temperature of the melt will be changed by the energy of the physical change, while that of the neutral body remains subject only to passive heat transfer. Thus, the actual liquidus temperature of each melt can be measured with extreme precision, and isothermal or programmed cooling methods of LPE can be precisely and reliably controlled under production conditions.
