Title: Process for lysing mycobacteria
Inventor: ROBSON JILLIAN A
IPC: C12Q1/68
Filed: 1992-12-04
Granted: 1998-12-29
Abstract: The invention provides a rapid process for lysing Mycobacteria.  In one embodiment is provided a process for lysing Mycobacteria which comprises exposing the bacteria to a lysis effective amount of heat.    The process of the invention is particularly advantageous since only one step is involved, it is expedient compared to prior methods, and little instrumentation is necessary.  By practicing the present invention it is possible to lyse Mycobacteria with minimal effort.  In addition, practicing the invention results in liberating cellular components including deoxyribonucleic acid (DNA) from Mycobacteria.  Not only is DNA liberated, but the DNA is suited for subsequent analysis by way of probe hybridization, restriction enzyme analysis, and the like.

Title: Method and device for supplying animal feed into a feed trough
Inventor: FOERSTER MARTIN
IPC: A01K11/00
Filed: 1992-12-14
Granted: 1999-06-29
Abstract: A device for the controlled supply of animal feed includes a supply container, a feed trough with a side wall having an inlet, a conveying device with a drive unit connected between the supply container and the inlet of the feed trough, whereby the conveying device has an outlet opening that is coaxially arranged relative to the axis of the conveying device and the outlet opening is directly connected to the inlet of the feed trough.  A control unit is connected to the drive unit for switching on and off the drive unit. control flap is pivotably connected above the inlet and includes a control element that is connected to the control unit.  The control flap activates the control unit for switching on and off the drive unit depending on the amount of animal feed present in the feed trough behind the control flap or due to activation by an animal to be fed. This device ensures that an animal to be fed only receives its allotted amount of animal feed because only after emptying the feed trough a new feed distribution is possible.

Title: Super tir tac poc
Inventor: BOUCHARD MARCEL
IPC: A63F3/00
Filed: 1992-12-18
Granted: 1997-12-30
Abstract: Un jeu d'adresse et de stratégie qui peut se jouer sur presque toutes les surfaces (gazon, sable, eau, ciment, etc.) et qui peut se jouer aussi bien à l'intérieur qu'à l'extérieur de la maison. Ce jeu présente certaines similitudes avec le "tic-tac-toe". Le jeu comprend un cadre réceptif muni de neuf carreaux et de quatre groupes de disques dont deux groupes pour chacun des joueurs. Les carreaux représentent les cibles à atteindre et les disques représentent les projectiles. Un premier groupe de projectiles possède au moins neuf disques de même diamètre, densité et épaisseur. Un second groupe comprend trois disques de diamètre sensiblement plus grand que celui du premier groupe. En raison de leur diamètre plus grand relativement à l'ouverture des carreaux, ces seconds disques ajoutent au degré de difficulté d'atteindre les cibles. En contrepartie à cette difficulté accrue, les disques de grand diamètre ont le pouvoir de déloger les disques du compétiteur et de prendre possession d'un carreau. Les joueurs jouent à tour de rôle en utilisant d'abord les disques de petit diamètre, plus facile à loger dans les carreaux, pour ensuite utiliser, de façon stratégique, les disques de grand diamètre pour déloger ceux du compétiteur.

Title: Conjugated moieties for chelating paramagnetic metals
Inventor: PALACIOS PAUL
IPC: A61K47/48
Filed: 1992-07-10
Granted: 2000-05-16
Abstract: In this method, one attaches one or more chelatant molecules to a mono- or polyamino intermediate compound which is temporarily immobilized on a solid phase by a splittable bond. Thereafter, the bond is split to release the desired conjugate moiety, whereby a reactive site is generated at the splitting site. The conjugate can be coupled to a protein homing factor using that reactive site; the latter being single per chelatant molecule, undesirable cross-linking during conjugation is substantially avoided.

Title: Controlling vacuum level with a two-level vacuum system controller and adjustable speed drive
Inventor: GUO FANGJIANG
IPC: F04B49/06
Filed: 1991-12-06
Granted: 1996-12-24
Abstract: A low-energy-consuming apparatus and method for controlling vacuum levels in machine milking and other vacuum systems subject to air leakage utilizes in combina-tion a high vacuum reserve, a low-vacuum end (pipelines), a dual vacuum controller positioned between the high-vacu-um reserve (20) and the low-vacuum end and an adjustable speed drive (ASD) motor (26) on a vacuum pump (28) to regulate the delivered air to match the air usage in the low-vacuum end. The dual vacuum controller senses vacuum disturbances in the low-vacuum end and adjusts the flow rate of air from the low-vacuum end to the high-vacuum re-serve rather than using external air makeup, thus providing a controlled vacuum with minimum pressure variance and energy input.  Energy savings and demand reduction of about 50 percent (50 %) during milking are realized under the new system.

Filed: 1994-08-02
Granted: 2000-12-19
Abstract: A flat belt is rolled up into a tubular shape in which material is wrapped and conveyed between a pair of pulleys. While the belt is transformed from a tubular shape to a flat shape and vice versa, the belt passes through guide rollers in guide frames. The guide roller is provided to go away from a straight line between the outer circumferences of the pulleys, thereby preventing the belt from biasing or folding back. Also, a dummy pulley and expansion rollers are provided while the belt is transformed between tubular and flat shapes, thereby achieving the same results.

Abstract: The object of the disclosed system is the fast switching of high voltage and short duration pulses on loads which require high instantaneous intensities, in order to provide said pulses in both directions; the system is capable in switching narrow band signals, and therefore long duration signals. The system is based on a very low series impedance switching channel which is comprised of two high voltage capacitors in series with two rectifying groups connected in opposition and whose conduction status is activated by forced injection, through said groups, of a direct current controlled by a reactive network in series with a conventional low voltage unidirectional switch, thereby providing for its logical control from digital circuits TTL or CMDS. This system applies more particularly and immediately to wide band units which operate with high frequency radiations, particularly of ultrasonic type, and in fields such as diagnosis and non invasive medical treatment and non destructive tests or aeronautical and nuclear structures.

Granted: 2000-10-03
Abstract: A reinforcing panel (22) and process for making the same for use in reinforcing wood structural members uncluding laminated beams, wood I-beams, and trusses. The reinforcing panel is comprised of a plurality of synthetic fibers (24) that are arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The panel has substantially no transverse fibers. The fibers are maintained in position by a resin encasement (26) that completely encloses the fibers with the exception of some fibers that are closest to the surface. The surface of the reinforcing panel is treated so that those fibers (28) closest to the surface of the panel are caused to "hair up" so that the reinforcing panel may be used with nonepoxy adhesives which are commonly used in the laminated beam industry, such as resorcinal. The reinforcing panel of the present invention is fabricated by an improved pultrusion process which uses no mandrels, or woven mats and which provides for a selectable back pressure so that the fibers of the reinforcement panel are maintained in a state of tension during the resin cure, thereby: maintaining the parallel arrangement of the fibers, maintaining the longitudinal alignment of the fibers, and setting the initial strain of the fibers to decrease the initial deflection of a wood structure that is reinforced with the reinforcing panel of the present invention.
