Abstract: The present invention provides a process for the production of thin sections of biological tissue, especially for transmission electron microscopy. In the process a fixed tissue sample to be investigated is dehydrated by infiltration of a hardenable medium miscible with water and subsequently embedded in casting resin, whereafter thin sections are cut from the cast body resulting after hardening of the casting resin. Infiltration is carried out by warming the fixed tissue sample in a mixture of formaldehyde, melamine and water. During warming, the mixture forms water soluble monomeric methylolmelamines which infiltrate the tissue and undergo polycondensation to form water-insoluble polymeric methylolmelamine condensates in the tissue. The casting resin is preferably a melamine resin, and the resin is preferably prepared using a methylolmelamine ether solution containing polyethylene glycol.

Abstract: To avoid environmental objections in discarding by-products of refining and processing of fatty oils, fats or mineral oils, or other materials, especially those containing alkali metal ions or salts, such by-products are combusted with excess air or oxygen, preferably in a fluidized bed oven, using a bed material having a low silicon content, particularly those consisting mainly of titanium, calcium and/or aluminium oxides, at 600-950°C, preferably 800-850°C. The organic materials in the by-products are thereby converted into products which can be discharged without problems; the exhaust gases contain only low amounts of carbon monoxide and nitrogen oxides. By passing the combustion gases through a heat-exchanger,the heat generated can be used, e.g. to preheat the excess air for the process or to generate steam or heated water, which can be used economically in other parts of the plant. The process is particularly suitable for the combustion of soapstock, the water content of which has been reduced, e.g. by evaporation, if necessary.

Abstract: A centrifugal fan having the inner edges of the impeller blades (7) extending parallel to the impeller axis incorporates a circular damper plate (11) supported coaxially within the array of blades with its edge closely adjacent the inner edges of the blades, and movable in an axial direction so as to vary the useful width of the blades and thereby the flow rate. The damper plate, being separate from the impeller (2), may be supported in a non-rotatable manner and enables the fan to operate at an efficiency comparable with one having a radial vane damper, but is simpler mechanically as it requires only a single primary moving part.

Title: Turbo machine blading
Inventor: OLIVIER PAUL D
IPC: F01D5/22
Filed: 1983-06-17
Abstract: Turbo machine blading in which each blade (16) of a blade wheel (12) has a platform section (18) at its inner end and a shroud segment (38) at its outer end, opposite ends of the shroud segment (38) being formed with S-shaped machined end surfaces (44, 46) each including a plane circumferentially extending abutment surface (48. 50). Oppositely-facing abutment surfaces (48, 50) of adjacent blades (16) engage one another in a transverse radial plane (P-P) and provide frictional damping of circumferential blade vibrations as well as restraining the centrifugal untwisting of the spanwise-twisted blades (16) by counterbalancing the untwisting torques (T). The remaining portions of the opposed end surfaces (44, 46) of adjacent blades are separated by clearance space. The inward projection of the end surfaces (44, 46) of each blade do not intersect the platform section (18) of the blade so that these end surfaces can be machined simultaneously by a pair of spaced tools moved along a line of action which takes them past the platform section (18) without touching it, thus avoiding tool reversal. Each blade is provided with three conical locating protrusions (52. 54. 56) for locating the blade in a fixture for machining.

The UCM 10 includes a microprocessor and memory, by virtue of which it becomes tailored to the characteristics of a given device 32 to be controlled upon plug-in of the UCM into a bussed rack associated with a Communication Module 26 preprogrammed with the set values for the drive. A basic control system includes corresponding Electrical Interface Modules 30 and their associated Communication Module 36 interconnected via a serial data communication link 38 extending between the respective Communication Modules for the UCMs and ElMs. As an option, an associated UCM and EIM can be directly connected via parallel leads 40 for direct control of a drive unit. 
     Where appropriate, the basic system is incorporated with a plurality of other basic systems in a second level control system, accessed by a Programmable Logic Module 120. In turn, for large extended systems, such as may be utilized in a manufacturing plant, the second level system may be incorporated with a plurality of other second level systems, all intercommunicating via a data highway 112 and being accessed through a Supervisory Control Station 110.

Abstract: In a paper transport conveyor from a sheet feeder to a printing machine, the sheets are underlapped for speed reasons and for this purpose, the sheets are held and transported in a defined position using a conveyor table to which a vacuum is applied. In order to optimize the feed register in the printing machine in all states of operation, an additional conveyor device holds the sheets at the front gauges and aligns them. The vacuum at the conveyor table is quantitatively variable and the vacuum is so controlled according to operation as to be applied when sheets are required to be held on the conveyor table but interrupted when its action would obstruct the sheet alignment on the conveyor table.

Abstract: The cover sheet which is to be placed, is brought into a waiting position above a predetermined conveying path of the stacks of flat articles. The cover sheet is displaced from this waiting position onto one stack by means of a placing element arranged at the end of a piston rod of a piston cylinder unit. The piston-cylinder unit is pivotably mounted about an axis which extends at right angles to a predetermined travel or movement direction of the stack. In its rest position the piston-cylinder unit lies against a pad or buffer which keeps the piston-cylinder unit in an inclined position. By extending the piston rod, the cover sheet is placed onto a stack. The placing element which presses on the stack, is entrained by the further moving stack. Thus the piston-cylinder unit is deflected from its rest position. As soon as a detector detects such a deflecting movement, the detector generates a signal which triggers retraction of the piston rod. The reversal of the movement of the piston rod is thus effected in a simple manner. The inclination of the piston-cylinder unit together with the placing element permits positionally correct placement of cover sheets onto stacks of various heights without requiring a special control arrangement.

Abstract: A mold (11) for molding articles of plastic or other like materials, having a plurality of vertically extending internal passages (19), is connected by inlet and return conduits (32, 35) into a closed loop that includes a heat exchanger (20) partially filled with a liquid supply of a cooling fluid or a heating fluid. For cooling the heat exchanger (20) is positioned with its liquid level above the top of the mold, the inlet conduit (32) connects the lower part of the heat exchanger (20), below the liquid level, to the lower ends of the mold passages (19), and the return conduit (35) connects the upper ends of the mold passages (19) to the upper part of the heat exchanger (20); for heating these relationships are reversed. In operation the fluid changes its physical state at critical points in the mold passages (19), going from liquid to vapor for cooling and from vapor to liquid for heating; circulation in the closed loop is in response to the effect of gravity. Operation of the heat exchanger (20) is controlled to maintain a controlled pressure in the closed loop.
