Title: Method and apparatus for detecting and measuring elastic anisotropy
Inventor: SONDERGELD CARL H
IPC: G01N33/24
Filed: 1988-06-02
Granted: 1992-10-13
Abstract: ABSTRACT         A novel method for detecting and measuring elastic anisotropy in a sample of the earth's formations is provided.  A dyad of time series signal representative of the sample's response to imparted shear waves is recorded.  The dyad of time series signals can then be processed to detect and measure elastic anisotropy in the sample.  More particularly, the dyad of time series sig-nals are collected by imparting shear waves having first and second polarizations into the samples with a shear wave transducer and recording the sample's response to each of the imparted shear waves by shear wave transducers having first and second polarizations.  In one embodiment of the invention, the dyad of time series signals can be diagonalized to detect and measure elastic anisotropy in the sample.  In another embodiment, the dyad of time series signals can be processed for a plurality of rota-tion angles and the resulting rotated dyad of time series signals can be displayed to detect and measure elastic anisotropy in the sample.

Title: Probe for hydraulic expansion, including centring device
Inventor: SWARS HELMUT
IPC: B21D39/20
Filed: 1988-09-01
Granted: 1994-02-15
Abstract: Probe for hydraulic expansion, including centring device In order to prevent a probe (2) used for expanding tubes (1) in portions from having an uneven effect due to its eccentric position in a tube which is not completely straight, the probe given a slightly flexible design is provided with centring rings (11, 13) which flexibly rest on both the inner face of the tube and on the probe member. The flexible parts (7) of seals limiting the operational regions (8), along their circumference, then evenly and simultaneously contact the inner wall of the tube. The invention proposes several design possibilities for the centring rings. To facilitate their introduction into the tube, the process of introduction is accompanied by a process of lubricating the inner tube parts, a process which improves sliding and for which the hydraulic fluid required in any case may be used.

Abstract: PRIMARY PRESSURE-BALANCED PROPORTIONING VALVE               ABSTRACT OF THE DISCLOSURE The proportioning valve assembly (40, 140) may be screwed into a complementary-shaped opening in a master cylinder (10).  The valve assembly (40, 140) includes a differential area piston (50, 150) biased by a spring (70, 170) toward the outlet (21, 121) which communicates with the rear brakes.  The master cylinder (10) includes a pair of passageways (16, 18) which communicate primary fluid pressure and secondary fluid pressure directly to the differential area piston (50, 150) of the proportioning valve assembly (40, 140) to displace the piston (50, 150) to a balanced position.  If there is a failure of pressure in the primary brake circuit, the proportioning valve assembly (40, 140) actuates the differential area piston (50, 150) to permit fluid flow to bypass the piston (50, 150) and be communicated directly to the rear brakes of the vehicle.

Abstract: RUPTURE DISC PRESSURE RELIEF DEVICE            Inventors:    Gavin McGregor, Gloucester, Ontario William Wells, Winnipeg, Manitoba Mahmud Islam, Gloucester, Ontario Assignee:      National Research Council of Canada Ottawa, Canada Abstract A two-part concave-convex rupture disc for use in a safety pressure relief device comprises one part which is perforated with lines of small holes that introduce controlled weakness in the disc and the other part which acts as a seal. When the pressure in a fluid on the convex side of the discs exceeds a predetermined limit, the discs will reverse their direction of convexity and the metal of which the perforated disc is made will tear cleanly along the lines of perforation and rupture so as to release the fluid in which the excess pressure occurred.  The pressure at which the rupture occurs is determined by the choice of the size and spacing of the perforating holes, as well as the choice of the thickness, the material of which the discs are made, and the pressure used to form the discs.

Abstract: The present invention relates to a process for the manufacture of desulfurizing agents containing 1-6% by weight of chemically bonded water, based on calcium oxide-containing calcium carbide, for crude iron and steel melts. To this end, a molten mixture of calcium carbide and calcium oxide with a CaO content of 20 to 80% by weight is produced, which is allowed to solidify into a block. Next, the block which still has an average temperature of more than 400 DEG C., is rough-crushed to particles with a size of less than 150 mm and calcium oxide is added to the comminuted mixture, which still has a temperature of at least 400 DEG  C., in accordance with the CaO content desired in the end product.

Abstract: Combined construction plates are used as horizontal plates in buildings. A combined construction plate is formed of an element which for instance is cast of concrete, and of steel sheet, as well as of a bottom construction which can for example be beam-like or framework-like. Steel sheet, which in conventional applications is normally profiled, functions both as the reinforcement and the casting mould of the plate. The bottom construction is either a ceiling suspended from the plate and/or a beamwork supporting the plate. In the combined construction plate of the invention the junction between the concrete (1), the sheet metal (2) and the bottom construction (4) is achieved by means of such spike-like members (3) which penetrate the sheet metal (2) and reach through the concrete (1) and the bottom construction (4). The spike-like members are partly or wholly composed of the spikes located in the upper part of the bottom construction, and they can be dented. They can also consist of nails which are nailed through the sheet metal (2), particularly of double-headed nails, in which case the head of the nail remains slightly apart from the surface in order to improve the concrete grip.
