Abstract: In the method of producing slabs made of granulated stone materials and/or sand bound with a hardenable resin by compaction under vacuum and subsequent hardening of the resulting raw slab, in which, before the vibratory compaction, the mixture is spread with substantially uniform thickness on a support, the said support being protected by a highly resilient sheet material, the flat configuration of the lower sheet is replaced by a shaped configuration comprising a flat base and a peripheral frame projecting from the flat base for a predetermined height so as to define a seat of dimensions corresponding in plan to those of the slab to be produced, the aforementioned peripheral frame having a height which is lower by a predetermined amount than that of the final slab to be produced so that, when the completely flat upper sheet is placed on the upper surface of the mixture, a space of predetermined depth remains between the peripheral edge of the upper sheet and the top of the aforementioned frame.

Abstract: A veneer packet assembly and delivery apparatus (10); and, a method of assembling a packet (15) of veneer sheets (14) and delivering the assembled packet for incorporation into a billet being fed into a laminated veneer lumber press. A veneer sheet is aligned atop a first series of spaced horizontal members (18) which are then displaced downwardly by a selected thickness distance and longitudinally by a selected offset distance (32). Additional sheets are sequentially aligned at op the previous sheet(s) until a packet having the desired number of plys is assembled. The first members are then lowered between a second series of spaced horizontal members (42), to transfer the packet onto the second members. Transfer of the packet onto the input end of the press is controlled to precisely align the packet's forward end with the trailing end of a previously processed packet being transported int o the press.

Title: Magnesium pressure casting
Inventor: MURRAY MORRIS TAYLOR
IPC: B22D17/20
Filed: 1998-11-30
Granted: 2007-09-11
Abstract: The provision or use, for the pressure casting of magnesium alloy in a molten or thixotropic state with a pressure casting machine having a mould or die which defines a die cavity, of a metal flow system which includes a die or mould tool means which defines at least one runner from which molten magnesium alloy is able to be injected into the die cavity. The metal flow system is of a form providing for control of metal flow velocities within the flow system, whereby substantially all of the metal flowing throughout the die cavity is in a viscous or semi-solid state. Filling of the die cavity is able to proceed progressively by semi-solid fronts of metal moving away from a gate or other site of injection. The flow of magnesium alloy from the runner may be via at least one controlled expansion region of the metal flow system in which region the metal flow is able to spread laterally, with respect to its direction of injection, with a resultant reduction in its flow velocity relative to its velocity in the runner.

Abstract: A noise immuned gradiometer split shield coil for use in magnetic resonance detection, such as in Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupole Resonance (NQR). The coil is formed by a transmission line (50) configured as a magnetic field gradiometer. The transmission line has a conductor (58) which is electrically continuous through the coil, and a shield (60) which is split (56) at a position that causes the gradiometer to be electrically balanced. In this manner, the coil provides a high degree of internal shielding to reduce the effect of environmental noise pick-up. Such coils are also less sensitive to the effects of nearby conducting media.

Title: Gas turbine moving blade
Inventor: SUENAGA KIYOSHI
IPC: F01D5/18
Filed: 2001-02-02
Granted: 2005-05-24
Abstract: A gas turbine moving blade is provided which prevents occurrence of cracks caused by thermal stresses due to temperature differences between a blade and a platform while the gas turbine is being stopped. During steady operation time of the moving blade, cooling air enters cooling passages to flow through other cooling passages for cooling the blade, and then to flow out of the blade. A recessed portion having a smooth curved surface is provided in the platform near a blade fitting portion on the blade trailing edge side. A fillet of the blade fitting portion on the blade trailing edge side has a curved surface with curvature larger than that of a conventional blade fitting portion. A hub slot below the fillet, for blowing air, has a cross sectional area larger than other slots of the blade trailing edge. A thermal barrier coating is applied to the blade surface. By the above construction, thermal stresses due to temperature differences between the blade and the platform during gas turbine stoppage are made smaller and occurrence of cracks is prevented.

Abstract: A method of making a plastics stretch film comprises the steps of taking a cast or blown film of LLDPE at a temperature of between 50°C and 100°C, stretching it in two successive stretching steps, the first step having a stretch ratio higher than that of the second step, to cause both plastic and elastic deformation of the film. The film is then relaxed to substantially release all of the elastic deformation and winding the substantially relaxed film into rolls. Preferably, the first stretch ratio is in the range 1:1.70 to 1:1.80 and the second stretch ratio is in the range 1:1.85 to 1:1.95, and there is a reduction ratio of substantially 1:0.85 between the speed of the film during the second stretch rolling step and the speed of the film during wind-up.

Abstract: Selon l'invention, un signal acoustique désiré est extrait d'un environnement bruyant par génération d'un signal représentant le signal désiré, à l'aide d'un processeur (30). Le processeur (30) reçoit des signaux sonores de deux capteurs (22, 24) situés chacun à un emplacement différent. Les deux entrées reçues par le processeur (30) sont converties du format analogique au format numérique, puis soumises à une transformée de Fourier discrète en vue de générer des représentations de signaux spectraux discrets. Les signaux spectraux sont retardés pour faire passer un certain nombre de signaux intermédiaires correspondant chacun à un emplacement spatial diffférent relativement aux deux capteurs. Les emplacements de la source de bruit et de la source désirée et le contenu spectral du signal désiré sont déterminés à partir du signal intermédiaire correspondant aux emplacements de la source de bruit. Une transformée inverse du signal intermédiaire choisi, suivie d'une conversion numérique-analogique, produit un signal de sortie représentant le signal désiré, grâce à une unité de sortie (90). L'invention concerne également des techniques permettant de localiser de multiples sources acoustiques. Elle concerne en outre une technique pouvant améliorer la réduction du bruit dans de multiples sources, sur la base d'une réception mettant en oeuvre deux capteurs.

Abstract: According to this treatment, calcium is added to ultra low molten steel or low carbon which is aluminum killed (or in the course of being killed) in order to form non-metallic deoxidation inclusions that have a melting point which is below the casting temperature; the molten metal is maintained in the chain of treatment ranging from the ladle refining installation to the copper mold with a low minimum low magnesium content of approximately 2 ppm. The inventive method increases the scope of fusibility of the inclusionary population of steels, thereby improving the castability of high aluminum-killed ultra low carbon grades without the need for argon bubbling.
