Abstract: ABSTRACT OF THE DISCLOSURE COMBINATION MITRE AND TABLE SAW      A flip-over saw (10) is disclosed, which consists of a saw assembly (20) mounted on a table (16) through a pivot (28) on a pivot member (26) which is itself pivoted about an axis (92) to a pivot block (27) fixed on the table (16).  Pivot (28) enables the saw assembly (20) to pivot up and down to cut work-pieces supported on the table (16) against a fence (17).  To enable bevel cuts to be effected on the workpieces, the saw assembly (20), through its pivot member (26), is pivotable about the axis (92).  The pivot member (26) has a projection (88) which is received in a semi-circular slot (90) in the table (16).  The projection (88) is retained at the centre of rotation of the pivot member (26).  The pivot member (26) is supported on a segment of the pivot block (27) and secured thereto by a bolt (170).  The pivot member (26) has an arcuate slot (173) through which to receive the bolt (170).  The axis (92) is located between the table's upper and lower surfaces, and the use of the bolt (170) and slot (173) combination together with the projection (88) provides improved stability of the bevel pivot.

Title: Absorbent article having a body-accommodating absorbent core
Inventor: LASSEN FREDERICH O
IPC: A61F13/53
Filed: 1994-10-25
Abstract: An absorbent article for absorbing body fluids is provided having an absorbent core positioned between a fluid-permeable cover and a fluid-impermeable baffle. The absorbent core includes a central, longitudinal flexure axis which substantially extends the length of the absorbent core. The central, longitudinal axis generally divides the absorbent core into first and second longitudinal members having an outer boundary and wherein the first member has a second flexure axis and the second member has a third flexure axis. Flanking the outer boundary of the first and second members are a third and a fourth longitudinal absorbent member, respectively. The third and fourth absorbent members are positioned so that, when said absorbent article is subjected to lateral compressive forces, the first and second members preferentially bend convexly upward, and said absorbent core generally acquires a "W" shaped configuration.

Inventor: DEAN DAVID M M
IPC: H04N13/363
Filed: 1995-04-11
Abstract: Stereoscopic images are presented using so-called "alternate eye" projection while blocking the viewer's respective eyes alternately and in synchronism with the display of images so that the viewer's left eye sees only left eye images and the right eye sees only right eye images. Blocking is effected using electro-optic liquid crystal shutters each of which has a front linear polarizing filter with a defined axis of polarization. The respective shutters for the viewer's two eyes are oriented so that the said defined axes of polarization are at an angle with respect to one another. The projected images are linearly polarized so that the left eye images are polarized along an axis that is parallel to the defined axis of the electro- optic shutter for the viewer's left eye and the right eye images are polarized along an axis parallel to the defined axis of the electro-optic shutter for the viewer's right eye. The invention significantly reduces perceptible ghosting even where high contrast images are projected, such as dark figures against a white background.

Abstract: Dans un support servant à tenir le biberon du bébé en place lors du boire, le parent est porté à utiliser une petite couverture plié sur le thorax du bébé mais cette couverture tien le biberon sans trop d'efficacité. Dans la présente invention, il sagit d'un support qui épouse la forme générale du thorax de l'enfant. Ce support est muni d'une parti en forme de " U " servant à tenir le biberon en place lors du boire. La présente invention se rapporte à un support servant à tenir efficacement le biberon du bébé lors du boire. Il est d'usage courant d'utiliser une petite couverture pour appuyer le biberon du bébé afin qu'il puisse boire seul mais le biberon n'est jamais tenu en bonne position nous devons constamment le replacer au moindre mouvement de l'enfant. J'ai découvert qu'en fabriquant un support à biberon moulé à la forme du thorax du bébé, il est pratiquement impossible que le bébé perdre son biberon à moins qu'il le rejette de par lui-même. Ce support à biberon est rapidement installé et n'encombre pas l'enfant. Il est aussi efficace à la maison, dans des endroits publiques tel que le restaurant ou encore, en automobile. Dans certains pays, lors que les gens sont à bord d'un véhicule, ils ne peuvent tenir leur enfant dans leur bras. Grasse au support à biberon, le bébé peut rester confortablement assit dans son siège et boire en toute sécurité. Ce support à biberon permet à bébé de boire seul et permet au parents de vaquer a d'autres occupations. Ce support est efficace jusqu'à ce que bébé soie en mesure de tenir seul son biberon.

Patent CA-2157942-A1 (CA)
Inventor: WONG PETER PUI-TAK
IPC: E04H9/02
Filed: 1995-09-11
Abstract: A device-for seismic isolation is invented by the use of sealed hydrostatic uplift pressure to reduce the loads of a building, structure, or heavy equipment. After the reduced frictional force is overcome the structure undergoes horizontal sliding motions, thereby reducing the seismic induced stresses. The present invention is economical and suitable for all types of buildings, ranging from family homes to power generation stations. It utilizes the space between the Upper and Lower Foundation Mats by dividing it into pressure chambers, fitting the mats with bearing plates, sealing the chambers off, and then pressurizing them by elevated liquid tanks or compressed gas cylinders. Pressure chambers may be allocated underneath asymmetric heavy weights for reducing the danger of excessive torsional in-plane rotation of the Upper Foundation Mat under earthquake. The momentary compression and de-compression of the pressure chambers would regulate the net structural load, thereby counteracting both the main and localized vertical shocks. The reliability and low cost of the present invention will enable seismic isolation to become an affordable household safety feature for people dwelling in high-seismic areas.
