Abstract: A clamp having an U-shaped clamp body (1) which engages a profile such as a rectangular or square pipe (2) on three sides (3, 4, 5), while the fourth side (6) of the profile is engaged by a bolt (7) which is secured by a nut (8) and extends through conical holes (9, 10) in the free legs of the clamp body (1).  Conical washers (11, 12) on the bolt (7) engage the conical holes (9, 10) on the far side from the pipe (2), meaning that the bolt (7) is located somewhat eccentrically in the holes (9, 10).  Tightening the bolt (7) by means of the nut (8) makes the clamp body (1) squeeze the top side (3) and bottom side (4) of the pipe (2).  The conical washers (11, 12) in the conical holes (9, 10) make the bolt (7) squeeze the pipe (2) in the direction of the back side (5) of the pipe. The pipe (2) is thus squeezed from all sides, giving a strong and stable clamp connection.

Patent CA-2182550-A1 (CA)
Title: Exercise Device
Inventor: BRISTER TIMOTHY G
IPC: A63B22/20
Filed: 1996-08-01
Abstract: A lightweight exercise device offers variable resistance, including assisted resistance, for strengthening and conditioning various parts of the body. The device may be strapped to the user's back and is provided with rollers for contact with a wall, door, pad, or floor. The rollers are mounted on rotatable axles on the rear face of the device and operate in conjunction with a tensioning system which uses durable elastic cords or bands. As the rollers are rotated in one direction, the cords or bands wind about the axles thereby progressively increasing the cord or band tension. This increased tension thereby increases the resistance to rotation of the axles and the rollers mounted thereon. As the rollers are rotated back, the cords or bands unwind and the roller resistance decreases. The cords or bands may be wound by rolling the rollers or, in one embodiment, by turning a tension preadjustment crank connected to an intermediate axle. In one embodiment of the invention, the cords are connected to cams maintained on the axles. The cords or bands are easily connected to the axles so that the range of resistance provided by the device may be changed simply by changing the size and flexibility of one or more cords or bands. The device is of particular use in performing exercises for the legs, shoulders, and abdomen.
Patent CA-2183058-A1 (CA)
Inventor: MCINNES ROSS GORDON
IPC: A61J11/00
Filed: 1995-02-09
Abstract: A teat for feeding liquids to animals has fastening means enabling the teat to be fastened to a source of liquid such as pipe or drum in use to project outwardly from the source. The teat is resilient having an outer end (9) which is closed apart from a slit (11) in it which slit is itself normally adapted to be closed to provide a liquid seal. The closed outer end is preferably concave, coned, cusped or otherwise reentrant. Integral reinforcing means such as webs are located internally on either side of the slit so that if the end of the teat is squashed or compressed by sucking forces exerted by the animal with components along the direction of slit, the reinforcing means causes the slit to be stretched open, thereby allowing liquid to flow out of it in use. The pulling or stretching action allows an acceptable flow rate from a comparatively small slit which is less prone to tear than a large split. Also a wall-stiffening web is provided, preferably as a transverse web (101) integral with the reinforcing means webs, extending from at or near the slit towards the inlet end of the teat, to provide internal stiffening, and acting in conjunction with the resilients to hold the slit closed when no sucking is occuring.

Abstract: La présente invention concerne une substance de remplissage pour prothèses implantées par voie chirurgicale, laquelle substance est à base de triglycérides synthétiques dont la viscosité est essentiellement supérieure à celle des triglycérides naturels. La composition à base de triglycérides est constituée de chaînes alkyle saturées réduisant ou limitant le potentiel d'oxydation des chaînes alkyle. En effet, l'oxydation de ces chaînes alkyle serait à l'origine de la formation de groupes peroxyde ayant des effets néfastes sur la biocompatibilité entre implant et substance de remplissage. La viscosité de la substance de remplissage est de préférence essentiellement équivalente à celle d'un sein normal de femme. A température ambiante, la substance de remplissage à base de triglycérides synthétiques peut présenter une viscosité plus basse proche de l'état liquide, la rendant apte à être utilisée dans des dispositifs gonflables. La présente invention concerne également des prothèses contenant la substance de remplissage caractérisée par lesdites viscosités et propriétés d'antioxydation requises, de même qu'un procédé de préparation de la substance de remplissage.

Title: Method for seismic data processing using depth slice decomposition
Inventor: JUSZCZAK JAMES W
IPC: G01V1/28
Filed: 1995-05-19
Abstract: A method of processing geophysical data on a parallel processor involves decomposition of an analysis cube into depth slices, a second decomposition of a data acquisition cube into traveltime slices, and determination of a variably dimensioned analysis aperture. Precomputed traveltimes are stored in packed format to minimize storage volume and data bandwidths. A processing simulation is performed to optimize the stored sequence of the seismic trace data and to minimize traveltime input/output demands. The method preferably assigns input/output, analysis, or control tasks to each processor, with depth and traveltime slices assigned to each analysis processor. The method relies on staged access of traveltime fields from high speed mass storage (104) to disk storage (108) and via the input/output processors (100) to analysis processor memory. Seismic trace data are also staged, preferably from tape storage to disk storage to processor memory, and preferably are broadcast under the control of a host computer. The method allows multiple common offsets to be simultaneously processed, and can be carried out on any type of parallel processing computer.

Title: A smooth rain-responsive wiper control
Inventor: TEDER REIN S
IPC: B60S1/08
Filed: 1996-05-01
Abstract: An automatic windshield wiper control system responds to sensed moisture in a manner which is responsive to changes in conditions. Moisture (40) and noise (43) sensitive signals are digitized (11), and a functional block (42) detects the reversals of the moisture sensing signal towards a quiescent level. These reversals are considered rain events and on ongoing measurement of the frequencies of these events are produced. The resulting signal is representative of the flow rate of raindrops impinging upon the moisture sensor. A resulting rain intensity signal (49) permits rapid but bounded response to sudden changes in conditions and an appropriate wiper actuation rate (73) is determined. The control strategy features hysteresis, giving the system the propensity to continue operating in a given mode.

Abstract: A light directing optical structure is formed of a light waveguide (40) preferably made of clear plastic; attached to or formed with the waveguide are a multiplicity of prisms (42). Each prism (42), due to its index of refraction, provides an aperture where light may escape the waveguide (40) rather than remain confined due to total internal refraction. The light escaping the waveguide (40) is reflected from a side face (32) of the prism (42), and redirected in a desired direction. The propagation paths within the waveguide (40) are such that the light emerging through the aperture is of only a fairly closely constrained range of angles; as a result the light that is redirected by the side face of the prism is of a similarly constrained range of angles. The geometry of the prism (42) can be optimized to direct the output light perpendicular to the plane (33) of the waveguide (40), or at a desired angle other than perpendicular. The optical structure can receive a light input along an edge, or along several edges, and its output beam is perpendicular to the structure or at some desired angle other than perpendicular. There is no restriction on the distribution and uniformity of the light input, yet the output is a directed and intensity controlled light source. Configurations are disclosed adapting the structure to several different possible light distribution patterns.
