Abstract: The cutting head 10 for a surgical reamer has a leading end 12 for insertion into a bone canal 60 and a trailing end 13 for attachment to a drive shaft 16. The cutting head has a cutting surface formed about an axis of rotation of the cutting head. The cutting surface is formed by the rotation of the cutting edges on a plurality of flutes 20 spaced around the axis of rotation. Each cutting edge has a first portion 26 spaced a predetermined radial distance from the axis of rotation at the tip portion 22 and terminates at a terminating point 30 which is at a greater radial distance from the axis of rotation than the starting point 28. The cutting edge on each flute 20 has a second portion 32 having a starting point 34 at the trailing end 24 of the cutting head 10 which is at a second predetermined radial distance from the axis of rotation. The second portion 32 extends axially towards the tip portion 22 and terminates at a point 36 at a greater radial distance from the axis of rotation than the starting point 34 thereof. A third curved portion 38 starts at the terminating point 30 of the first portion 26 and terminates at the terminating point 36 of the second portion 32 and intersects the first and second portions tangentially. <IMAGE>

Abstract: A method for control of ethylene biosynthesis in plants comprising a vector containing a selective gene under plant promoter control, and a DNA insert comprising codons for a functional heterologous polypeptide having AdoMetase activity and flanked by a plant promoter on one side and a polyA signal sequence on the other side; and, transforming a plant host with said vector wherein the plant host transformed thereby is capable of expressing the heterologous polypeptide having AdoMetase activity under the control of said control region. The presence and expression of AdoMetase in transgenic plants lowers AdoMet levels and generates an inhibitor of ACC synthase causing a corresponding decrease in ethylene biosynthesis and precursor availability. The current construction of transgenic plants containing a copy(s) of the T3 AdoMetase gene allow for construction of plants that will control ethylene biosynthesis resulting in fruits, vegetables, and flowers which have improved shelf life and preservation qualities.

Abstract: A method and an apparatus for orienting amorphous plastic material causes the material to be displaced through a gap with a smallest gap width less than the material thickness of the plastic material. During such displacement, the material is oriented, under the formation of a transition zone (18) between as yet unoriented (thicker) material (16b) and oriented (thinner) material (16a). The material is displaced at a speed entailing that crystallization energy released on orientation reaches the defining surfaces (14, 17) of the plastic material at a point in time when the material has already assumed its reduced thickness. The apparatus includes a drawing ring (50) and a mandrel (60), between which the gap is formed. When the plastic material enters into the gap, the gap is of a width which substantially corresponds to the material thickness of the amorphous material. In the direction of displacement of the plastic material, the gap width is reduced so as to be less than the material thickness of the amorphous material, but exceeds the material thickness of the oriented material.

Abstract: Method of producing a cooking vessel with a jacket and bottom of stainless steel as well as a plate of material with good heat conduction underneath the bottom. In a hammering press with male mould and female mould, the assembly is subjected to single or multiple impulse pressing at a temperature set according to the material of the plate. As a result, the plate is intermetallically bonded to the bottom. The jacket is provided, at least in certain regions, with a decorative and/or technical, for example identifying, enamel coating, which is applied to the jacket with the aid of an enamelling sheet as a support capable of enamelling and is burnt in as enamel. This support capable of enamelling is chosen such that the forming of the enamel takes place at the temperature set according to the material of the plate. This support capable of enamelling is applied to the cleaned jacket. The cooking vessel with its support capable of enamelling is heated to the temperature set according to the material of the plate. Thereafter, the assembly is subjected to the impulse pressing without intermediate cooling from the same heat with the already formed decorative technical enamel coating.

Abstract: A process for producing silica brick by firing silica stone mainly comprising silica and containing 0.2 to 5 wt % of solidified molten soda lime silicate added thereto, whereby silica brick with a lowered content of residual quartz can be produced readily and efficiently even by using a silica stone which difficultly causes the transformation of quartz. The process comprises crushing silica stone, adding thereto solidified molten soda lime silicate and a binder, molding the mixture, and firing the molding at 1350 to 1500 DEG C to cause a reaction between the silicate and the silica in the silica stone to thereby cause rapid transformation of the silica into cristobalite and tridymite.

Abstract: A method and device for controlling sleep disorder breathing utilizes variable pressure. The compressor supplies air at a relatively low pressure to the user's air passages while the user is asleep. A pressure transducer will monitor the pressure and convert the pressure into an electrical signal. The electrical signal is filtered and processed to compare it to the characteristics of waveforms that exists during snoring. If the envelope of the waveform exceeds an average threshold value in duration and in area, then the microprocessor will consider the envelope possibly associated with a snore. If a selected number of envelopes of this nature occur within a selected time period, then the microprocessor considers snoring to exist and increases the pressure of the compressor. If snoring is not detected within a certain time period, then the microprocessor lowers the level gradually.

Abstract: Steroidal and non-steroidal glycosides and a method of producing them are provided, wherein aglycon compounds are glycosylated with tri-O-acyl glucal using molecular or ionized halogen as reaction catalyst. The aglycon, which may be a non-steroid or a steroid having a reactive functional group (e.g., -OH, -SH, -COOH, -NH2, -NHR1) such as a cholesterol, is glycosylated, wherein the glycosylation is performed in a single step. For example, a steryl pyranoside is oxidized to the corresponding 7-ketosteryl di-O-acyl-pyranoside, which is selectively reduced to provide the corresponding 7-beta-hydroxysteryl 2,3-dideoxy-alpha-D-erythro-hex-2-enopyranoside. These steroidal and non-steroidal glycosides possess valuable pharmacological properties. In particular, the cholesterol glycoside exhibits a selective cell-destructive activity on malignant cell, in vivo, and is substantially free of side effects on normal cells. The glycosides possess useful pharmacological properties which are the same as their respective unglycosylated aglycons, which properties include a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.
