Abstract: La présente invention concerne un appareil et un procédé de régulation de la circulation de l'air froid dans un réfrigérateur. Avec cette invention, l'air froid qui a été refoulé dans une chambre de réfrigération (35) est recirculé de sorte que l'intérieur de ladite chambre peut être maintenu à une température relativement constante et que l'air froid (température relativement basse) ne peut pas aller alimenter un évaporateur (39). En particulier, l'installation selon la présente invention facilite la circulation de l'air froid dans la partie basse de la chambre de réfrigération (35). Ainsi, la température de la chambre (35) dans son ensemble peut être maintenue à une valeur constante, et la température du compartiment pour légumes (36) réglée à la valeur requise. Selon un mode de réalisation, on trouve à cette fin un conduit de circulation (50) conçu pour aspirer l'air froid autour du compartiment pour légumes (36) et le refouler dans la partie relativement haute de la chambre de réfrigération (35). Une entrée (51) du conduit de circulation (50) est disposée près de la partie inférieure arrière du compartiment pour légumes (36), et une ouverture dudit conduit (50) débouche au-dessus du rayon (35') correspondant au haut du compartiment (36). De plus, la sortie (52) est équipée d'un ventilateur (54).

Title: Apparatus for the elastic properties measurement of materials and method therefor
Inventor: ALLAIRE CLAUDE
IPC: G01N3/34
Filed: 2003-08-14
Abstract: Knowledge of the elastic properties of materials is of prime importance. These properties do not only reflect the extent of bonding in the material, but also permit characterization of its behaviour under stress.      For heterogeneous materials such as refractories and carbon electrodes, the measurement of such properties is difficult to achieve with high level of repeatability. The present invention is directed to a novel method and apparatus allowing the measurement of the Elastic and Shear Modulus, as well as the Poisson's ratio of heterogeneous materials, at room and high temperature, according to a non destructive acoustic technique.

Title: Rebar insertion device
Inventor: FIFIELD JOHN
IPC: E21D20/02
Filed: 2004-03-09
Abstract: An apparatus and method for inserting rebar bolts during mining ground or roof support operations is disclosed. The apparatus is removeably secured to the front head of an extendable stoper drill. The apparatus has a clutch assembly, comprising a roller, slide plate and an opposing backing plate. The axis of the roller is free to move along the slide plate at an oblique angle away from the pinch arm in the direction of extension. Extension of the drill causes the roller to apply pressure on a rebar bolt held between the slide plate and the backing plate locking it in place until the drill is retracted. When the drill is retracted, the roller moves away from the backing plate, releasing the pressure, and permitting the apparatus to slide down relative to the rebar bolt to grip the rebar bolt at a lower point. When the drill leg is next extended, the rebar bolt can be further driven into the hole penetrating the column of resin. The rebar bolt may be inserted using only the apparatus and the drill. The drill can be used in a normal fashion to drill holes, to spin the rebar bolt and to tension the rebar bolt with the apparatus mounted thereon.

Title: Foam material-based spring mattress
Inventor: TORRES CERVERA MANUEL
IPC: A47C27/15
Filed: 2004-04-14
Abstract: A spring mattress is described that uses a number of elastic springs, distributed spatially in a predetermined pattern, with sufficiently varied configurations, obtained by cutting and hollowing out an initial sheet of foam material of an appropriate thickness. The configuration chosen produces recessed portions on one or more sides of the spring elements, of varying sizes and depths, and protruding portions on one or more sides, likewise of varying thicknesses and projection distances. The springs forming the mattress are in one piece at their lower ends with the remaining continuous laminar portion of the original sheet, and, in an alternative version, they can be joined at their upper ends to a continuous or discontinuous laminar sheet, to which they are fixed by gluing or using a similar operation.

Inventor: HAAG PHILIP E
IPC: H01R13/623
Filed: 2001-10-12
Abstract: A twist-lock connector assembly for securing an engaged electrical plug to an electrical socket (or outlet) that includes a rotatable cylindrical sleeve disposed enclosing an electrical plug. In use, the electrical plug is inserted into the socket and the cylindrical sleeve is rotated about a 1/4 turn. This causes the inner disposed nubs of the sleeve to lockingly engage the outer disposed threads of the upstanding cylindrical wall of the cover plate. This prevents the electrical plug from being accidentally pulled loose from the socket. One aspect of the twist-lock connector assembly provides securing engagement of an electrical plug to a female socket portion of an extension cord. The female socket is enclosed by a retractable sleeve provided with engaging nubs adapted to lockingly engage the external threads of the rotatable sleeve of the electrical plug. Another aspect of the twist-lock connector assembly provides rapid twist-locking connection between a female connector of an extension cord and the male connector end of a whip end of handle portion of an outdoor power tool.

Inventor: VICTOR JAY
IPC: H01B11/00
Filed: 2004-05-18
Abstract: An improved structure of audio signal cable, the features of which are that the audio signal cable is comprised of arrayed solid and tinsel wire conductors.   After each of the conductors are bundled, they are placed into a surrounding insulation. The solid conductors are of a circular and a flat, thin shape. The solid conductors are of differing larger and smaller diameters and, furthermore, disposed in unequal quantities. The smaller diameter tinsel wires are twisted to increase distance and enlarge their surface area to reduce skin effect for better high frequency transmission, while the larger diameter conductors enable the rapid conveyance of low frequencies. As such, the present invention achieves the synchronous phasing of high and low frequency signals.
