Abstract: ABSTRACT      This invention provides versatile, portable apparatus for molding hollow, plastic-walled articles of various types, the apparatus having controlled, programmable means for distributing raw plastic in a mold by rotating and rocking the mold about two different axes.  Means for heating the mold are provided which can be adjusted and programmed to produce zones of different temperature, leading to corresponding variations of wall thickness in the molded article.  The apparatus can be employed in a method to produce plastic vessels having through-wall fittings, strengthened by a thicker wall in the vicinity of the fitting.

Abstract: Abstract of the Disclosure Ground Engaging Tool Tip retainer mechanisms are designed primarily to secure a tip to an adapter nose for use in a variety of applications.  In the subject arrangement, the holder substantially encircles the outer diameter of a spring retainer.  When assembled, the holder and spring retainer are placed in a recess of the adapter nose and a bore of the spring retainer is substantially axially aligned with a transverse bore of the adapter nose.  Furthermore, the holder is made of an elastomeric material and has a thickness greater than a depth of the recess.  Consequently, upon assembly of the tip on the adapter nose, the pin may be easily inserted through the respective holes of the tip, the transverse bore of the adapter nose, and the properly aligned bore of the spring retainer.  Due to the compressive forces of the elastomeric holder, the tip is snugly held against the adapter nose to substantially eliminate the vibrations between the tip and the adapter nose.

IPC: C12N15/82
Filed: 1990-01-26
Abstract: 1. Pseudo-operator sequences may be located in (or inserted into) plant genomes and utilised to drive expression of foreign genes. These pseudo-operator sequences are nucleotide sequences which are present at a suitable location in a gene at which repressor binding will lead to inhibitation or enhancement of gene expression. The disclosed technique permits the design of altered specificity repressors, which bind the pseudo-operators.

Filed: 1990-04-11
Abstract: A veneer lathe apparatus control system and method are described for automatic adjustment of lathe components which engage the log during peeling in response to reduction of the log diameter and to changes in the surface temperature of the log. The lathe components which are automatically adjusted include the lathe knife pitch angle, the knife gap spacing from the nose bar, and the radial positions of backup idler rolls and of core drive rolls. A computer control system is employed for such automatic adjustment of the lathe components in response to control signals produced by a temperature sensor which senses the surface temperature of the log and by a lathe carriage position sensor whose output indicates the diameter of the log as it is being peeled. Adjustment curves selected by the computer, such as pitch angle profiles and knife gap curves, are stored as data tables in the data memory of the computer. These adjustment curves include families of curves for many species of wood with each family having curves of different log temperatures to provide offset temperature adjustments between adjacent curves for different temperature ranges.

Abstract: ALLOYING LOW-LEVEL ADDITIVES INTO    HOT-WORKED Nd-Fe-B MAGNETS            Abstract of the Disclosure Diffusion alloying techniques are used to introduce low level additives into hot-worked Nd-Fe-B magnets.  The powdered metal is added to the rapidly solidified ribbons of the magnetic alloy prior to hot working.  Diffusion alloying during hot-working permits the final chemistry of the magnet and more specifically the grain boundaries to be determined during the final processing steps.  Elements which diffuse into the matrix, such as zinc, copper and nickel, enhance the coercivity by as much as 100 percent in die-upset magnets.  At optimum levels, approximately 0.5-0.8 weight percent, the additives did not diminish the remanence or energy product of the magnet.

Title: Screw device for fixing prostheses to bones, a method for applying the device, and the relative instrument
Inventor: VRESPA GIUSEPPE
IPC: A61B17/86
Filed: 1990-10-25
Abstract: In a screw device (10; 80) for fixing prostheses to bones, the threaded shank (14) comprises a core (32, 34) of overall frusto-conical shape. The screw has a cylindrical neck (12) of diameter equal to or greater than the maximum diameter of the thread. This latter is of two different types, namely a first thread (26) of large pitch for fixing into the trabecular bone tissue (52) and a second thread (28), which can be of the self-tapping type, for fixing into the cortical bone opposite the point at which the screw is inserted into the bone. The second thread (28) has a number of starts which is a multiple of that of the first thread (26). For orthopedic use the screw (80) can comprise a third thread (128) on a part of the neck (112) for fixing into the relative cortical bone (50).      A method for applying the screw device (10; 80) consists of forming a precision hole (90) in the bone, tapping said hole with a tapper (60; 100), and screwing the screw (10; 80) into it. The precision hole (40) is obtained by using a cutter (100) in the shape of an inverted "wedding cake", then reaming the obtained cavity with a manual reamer (1-10).

Title: Educational aid with substitutable magnetic items
Inventor: HOUSE CHARLES E
IPC: G09B1/08
Filed: 1991-01-21
Abstract: ABSTRACT OF THE DISCLOSURE            An educational and entertaining device stimulates learning, creativity,  imagination,  and artistic interpretation.  The principal elements in the device are  flexible  magnetic  character  pieces  and geometrically shaped metallic chips which, when magnetized,  form solid replicas in the shape of the flexible magnetic character pieces.  The invention is activated by placing a preformed,  flexible magnetic alphabet letter, numeral, animal or other character piece on an image board located in a bottom half of the device.  Alternatively,  separate magnetic character pieces may also be placed on the image board to form a series of artistic impressions.  Once the device is closed and secured, the user shakes the device, thus causing the geometrically shaped metallic chips to form an  impressionistic picture.   All  of  the alphabet letters, numerals, animals, and other artistic shapes may be created by repeating the process with different flexible magnetic character pieces.

Cette estimation est itérative et comprend les étapes suivantes: l'analyseur Viterbi calcule des signaux d'erreur de transition entre un ancien état et un nouvel état à l'aide d'une réponse impulsionnelle partielle précédente; l'analyseur Viterbi (VIT1) sélectionne parmi les signaux d'erreur de transition ceux qui sont les meilleurs (ei,1...ep,16), les anciennes réponses impulsionnelles partielles (Ci(n-1),...,Cp(n-1)) et les vecteurs de transition (Si1,...Sp16). Les circuits d'estimation (CEST1,...CEST16) estiment les nouvelles réponses impulsionnelles partielles (C1(n),...C16(n)) pour le nouvel état (N) à l'aide des anciennes réponses impulsionnelles partielles (Ci(n-1),...Cp(n-1)), des vecteurs de transition Si1,...,Sp16) et des signaux d'erreur de transition (ei1,...ep16).
