Title: Poudre traitee par fusion contenant un agent de repulsion, composition retardant l'evaporation et des moyens destines a favoriser la culture de plantes et/ou l'elevage d'animaux
Inventor: O'BRIEN ROBERT NEVILLE
IPC: B01J19/16
Filed: 2003-03-04
Abstract: L'invention concerne une composition retardant l'évaporation mise au point de façon qu'elle soit largement appliquée à la co-distribution de substances chimiques non feuillogènes et de substances feuillogènes. Les substances non feuillogènes sont aussi bénéfiques pour la culture de plantes et/ou l'élevage d'animaux dans leurs propres utilisations que les substances feuillogènes à base d'alcools gras car elles permettent d'économiser l'eau. Un concept précédemment divulgué d'ionisation due à l'eau qui améliore l'épandage sous l'effet de la répulsion mutuelle de particules est réalisé à l'aide d'un acide dicarboxylique, de préférence de l'acide oxalique, sous la forme d'un agent de répulsion ionique. L'invention décrit le moyen d'éviter l'estérification entre l'alcool contenu et l'infiltration d'acides dans le sol, ce qui représente un problème connu qui limite l'utilité des compositions feuillogènes émulsifiées.

Title: Method of utilizing the (n, gamma) reaction of thermal neutrons
Inventor: TELEKI PETER
IPC: G21G1/06
Filed: 1989-11-23
Abstract: ABSTRACT      The invention refers to a method of utilizing the (n, gamma) reaction of thermal neutrons, comprising the steps of arranging a target (2) before a source (1) of thermal neutrons, the target (2) having a front surface directed to the source (1) of the thermal neutrons and a rear surface lying behind the front surface, preparing the target (2) with a basic metal body (4) made of 70Yb and/or 74W, producing by the means of the thermal neutrons a me-tallic mixture including the basic metal(s) and at least one of the pairs of metals 71Lu + 72Hf and 75R3 +76?s and storing the metallic mixture for reducing its nuclear ac-tivity.

Patent CA-2004311-A1 (CA)
IPC: B23K11/24
Filed: 1989-11-30
Abstract: An arrangement for monitoring the quality of electric welds on bodies  for the production of cans. Welding parameter values (Fi), which have been measured on a number of bodies  found  to be  good are  statistically evaluated in an evaluation device.  For this purpose, an average welding parameter profile is determined.  Then a reject limiting-value band (Fg) enveloping the average welding parameter profile is determined from the mean values and the product of the standard deviation of the welding parameter values (Fi) assumed to be normally distributed and at least one sensitivity factor.  A permissible number of erroneous rejects per one million of welding spots is selected as a criterion for the sensitivity factor  so that, for example with 100 welding spots on a body of a medium-sized can,  every ten thousandth body will be accidentally rejected on the average.  For bodies produced following on the "learning phase", a comparator ascertains whether a welding parameter profile measured for these lies within the reject limiting-value band (Fg).  This quality control arrangement working on statistical methods is sensitive and precise since a fixed value is not simply selected for the width of the reject limiting-value band.

Title: Method and device for the production of wood sheets from cut wood
Inventor: BINDER HANS
IPC: G06T5/30
Filed: 1989-12-21
Abstract: A method for the production of wood sheets (10) from cut wood (2) substantially comprises the method steps of cutting the cut wood, which has been pre-dried if necessary in a conditioning apparatus (4), in a sawdust-free manner in a cutting apparatus (6), of drying the cut wood sheets (10) directly thereafter to low wood humidities, and of directly thereafter subsequently working the dried wood sheets in particular by a grinding process in a subsequent working apparatus (24). With the method according to the invention, wood sheets (10) of high quality can be produced, and at the same time the yield is considerably increased and the energy requirement is distinctly lowered.
Patent CA-2006858-A1 (CA)
IPC: A22C25/14
Filed: 1989-12-28
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for collecting fish eggs comprises a conveyor for transporting fish with the upper half of each fish inclined obliquely upward, a pair of upper and lower conveyor belts for holding the tail of each fish therebetween during transport, a pair of upper and lower conveyor belts for holding the trunk lower half portion of each fish therebetween during transport, trunk support portions and fish back restraining frames arranged alternately on the lower trunk holding belt, a head cutter disposed close to the terminal end of the conveyor, a member for pressing the abdomen of each fish after its head has been cut off, and an operating mechanism for the pressing member.         During transport on the conveyor, the eggs in the abdominal cavity of each fish move toward the tail of the fish under gravity, and the head is thereafter cut off by the cutter.  During the subsequent transport operation, the fish has its abdomen pressed by the member, is bent rearward about the portion thereof held by the trunk holding belts and is prevented from being further bent by the restraining frame in bearing contact with the back of the fish.  The member therefore fully exerts its pressure on the fish to completely squeeze out the eggs from the head cut-off face for collection.

IPC: H01H33/66
Filed: 1990-06-05
Abstract: ABSTRACT    A  cylindrical  coil  conductor  incorporated  in  a  vacuum interrupter  comprises  a  cylindrical  body with a plurality of inclined slits therein defining a plurality of current paths.          The  coil  conductor  is  uniformly cylindrical  to reduce radial magnetic fields, which tend to cancel the axial magnetic field generated by the coil conductor.  The cylindrical coil conductor electrically connects to the rear surface of a main electrode through a copper ring to maintain current on the periphery of the main electrode.  The front surface of the main electrode includes a ring-shaped protrusion to define a point of contact with an opposite main  electrode.   Current flows into the protrusion, through the main electrode to the copper ring, thereby defining a short current path with a minimal resistance.

IPC: G01P1/02
Filed: 1990-08-30
Abstract: A semiconductor strain sensor comprising a substrate having a lead hole in which a lead terminal is installed so as to be electrically coupled to an external circuit and a sensor chip joined with the substrate and having piezo-resistors to a bridge circuit.  A shell is joined with the front surface of the substrate by means of a projection welding technique after the back surface of the substrate is flattened, said sensor chip being covered by the shell and a space formed by the shell and the substrate being filled with a damping liquid.  The substrate is integrally coupled to the sensor chip through an adhesive, and spacers are added to the adhesive so as to keep the thickness of the adhesive to a predetermined value.  This arrangement can effectively prevent the propagation of the welding strain of the substrate into the sensor chip.
