Abstract: A sensor (12) system and method for determining the various Z-directional properties of a sheet (14) by measuring the ca-liper of a moving sheet (14) of material at a plurality of pressures. The invention employs a caliper gauge (10) and a set of pres-sure transducers (not shown) that can measure and send signals indicative of the caliper as well as pressures exerted on the sheet (14). The signals are then digitized by an analog-to-digital converter (not shown) and sent to a computer (30). The computer (30) uses the compressibility data to construct a compression stress-strain diagram where the slope of the curve in the linear region of the region of the curve is defined as the compression modulus of elasticity which can be empirically correlated to the tensile mod-ulus of elasticity for various grades of paper. The tensile modulus of elasticity can hen be used in various formulas to determine other Z-directional physical properties of the sheet (14) such as tensile strength, extensional stiffness and Scott bonding.

Title: Novel glycoside compounds and production and use thereof
Inventor: KLEMKE R ERICH
IPC: C07H15/18
Filed: 1992-07-21
Abstract: Novel glycosides, especially steroidal and non--steroidal glycosides, and a novel method of their production, are provided. For the novel method of producing novel glycosides, aglycon compounds are glycosylated with tri-O-acyl glucal using molecular or ionized halogen as a reaction catalyst. In this method an aglycon, which may be a nonsteroid or a steroid having a reactive functional group (e.g., -OH, -SH, -COOH, -NH2, -NHR1) such as a cholesterol, is glycosylated, such that the glycosylation is performed in a single step. For example, if a steroid, the resulting steryl pyranoside, is by oxidation converted to the corresponding 7-ketosteryl di-O--acyl-pyranoside. The latter pyranoside is selectively reduced to provide the corresponding 7-.beta.-hydroxysteryl 2,3--dideoxy-.alpha.-D-erythro-hex-2-enopyranoside. The steroidal and non-steroidal glycosides obtained in this way possess valuable pharmacological properties. In particular, the cholesterol glycoside in vivo exhibits a selective cell--destructive activity on malignant cells which activity is substantially free of side effects on normal cells. The glycosides possess useful properties, especially pharmacological properties which are the same as their respective unglycosylated aglycons. The properties may include a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.

Title: Process and apparatus for the fully automatic laying and folding of elongated textiles
Inventor: BELLA GUDRUN D
IPC: B65B25/20
Filed: 1994-02-07
Abstract: ABSTRACT   In the process and apparatus for fully automatic laying and folding elongated textiles such as stockings, panty hose and the like, four folding conveyors withcirculating silicone coated belts are used. The textile is transported from a first folding conveyor to a second folding conveyor which have the same running direction. Once the textile reaches a predetermined position, a card laying arm takes a wrapping card from a wrapping card magazine and places the card onto the textile. The second folding conveyor and a third folding conveyor positioned in parallel thereto are raised by means of a hydraulic device. The textile and the wrapping card are pulled-in between the second and third folding conveyors which are now operated in their opposite running directions. The textile is delivered 1/3 folded onto a fourth folding conveyor which is equipped with eight circulating silicone transport belts. The remaining folding operations take place on the fourth folding conveyor and are performed by first, second and third folding rakes, the third rake being adjustable. The third rake can be reoriented by 180° to produce end folding in left hand or right hand direction. The positioning of the textile on the folding conveyors is controlled by means of photo-detectors. After folding is complete, the textile is transferred onto a transport conveyor which has a deceleration and acceleration function. The eight circulating, silicone coated belts of the transport conveyor deliver the folded textile to a packaging station at the transport speed thereof. Seven stripping fingers are associated with the transport conveyor which prevent the textile becoming entangled therein. The whole apparatus and process is electronically controlled and, thus, provides the advantage of higher efficiency and speed compared with conventional machines.
