Patent CA-1302503-C (CA)
Title: Radio pager receiver capable of informing whether or not memory backup is correct
Inventor: OYAGI TAKASHI
IPC: G08B5/22
Filed: 1987-01-30
Granted: 1992-06-02
Abstract: Abstract of the Disclosure:            In a radio pager receiver which comprises a memory having a message area and an additional area and a message processor for processing a message signal into messages to store the messages in the message area, a specific datum is written (S6) in the additional area by the message processor.  Although the message processor and the memory are activated by main electric power of a power supply circuit, only the memory is backed up by backup electric power of a backup power source.  When the memory and the message processor are activated after once deactivated, the message processor judges (S2) whether or not the specific datum is correctly kept.          The message processor controls display (S3 and S4) of a result of judgement.  In the message area and the additional area, entries may be erased (S8) by the message processor when the specific datum is not correctly kept.  When the specific datum is correctly kept, the message processor may make a display unit display each of the messages together with an announcement which indicates whether or not the each of the messages is subjected to a backup operation by the backup electric power.

Title: Method of determining position and dimensions of a subsurface structure intersecting a wellbore in the earth
Inventor: HOLZHAUSEN GARY R
IPC: G01V1/50
Filed: 1987-03-19
Granted: 1991-01-15
Abstract: ABSTRACT OF THE DISCLOSURE          The growth of a hydraulic fracture increases the period of free os-cillations in the well connected to the fracture. Simultaneously, the decay rate of free oscillations decreases. The properties of forced oscillations in a well also change during fracture growth. All of these effects result from the changing impedance of the hydraulic fracture that intersects the well. Hydraulic fracture impedance can be defined in terms of the hydraulic resistance and the hydraulic capacitance of a fracture. Fracture impedance can be determined directly by measuring the ratio of down hole pressure and flow oscillations or indirectly from well head impedance measurements using impedance transfer functions. Well head pressure measure-ments can also be used to evaluate fracture impedance by comparing them to pressure oscillations computed with hydraulic models that include fractures with different impedances. Because impedance is a function of fracture dimensions and the elasticity of the surrounding rock, impedance analysis can be used to evaluate the geometry of the fracture by analyzing the data which results from free and forced oscillations in the well, and looking for a match between the data and theoretical models of projected shapes of the fracture.

Title: Metal halide lamp having heat redistribution means
Inventor: KEEFFE WILLIAM M
IPC: H01J61/34
Filed: 1988-05-06
Granted: 1991-08-27
Abstract: ABSTRACT     An improved metal-halide arc discharge lamp includes an arc tube having a substantially cylindrical body surrounded laterally by a substantially cylindrical heat-conserving sleeve within an evacuated outer envelope.  The ratio of the outer radius of the arc tube divided by the inner radius of the sleeve falls within an optimum range of approximately 0.54 to approximately 0.68, and preferably within a range of approximately 0.60 to approximately 0.63.  A lamp constructed in accordance with the invention exhibits improved luminous efficacy and color rendering in comparison to prior art counterparts.  The improved performance is believed to be attributable to the more nearly isothermal operation of the arc tube for a given wall loading.

Granted: 1995-07-25
Abstract: A railroad railway for rail-mounted vehicles capable of high speed travel includes a track grating formed of rails and ties with the ties partially embedded in a poured-in-place steel reinforced concrete slab.  The concrete slab is mounted on a continuous  concrete  substructure  with  a  separating  layer arranged between the slab and substructure.  A single layer of steel reinforcement is located in the concrete slab spaced below the ties.  The slab is dimensioned so that it serves only for plate-like stiffening of the track grating without any appre-ciable inherent bending resistance.  The slab is secured against longitudinal and transverse displacement on the substructure, while the substructure is dimensioned to absorb bending moments developed in the longitudinal direction of the rails.   The concrete slab  is divided  in the  longitudinal  direction by transversely extending expansion joints whereby sections of the slab can be replaced if damage occurs.   There is sufficient space between adjacent ties above the concrete slab to add sound absorbing material.
