Patent CA-1278972-C (CA)
Title: Temporary/portable nuclear fallout shelter
Inventor: HAMPEL VIKTOR E
IPC: E04G11/04
Filed: 1986-11-27
Granted: 1991-01-15
Abstract: ABSTRACT OF THE IVENTION       Significant, life-saving protection from airborne, radio-active (fallout) particles due to nuclear explosions, nuclear reactor accidents, and other releases of radioactive particulate is provided by a double-wall tent structure quickly erectable over a central trench hole.  The tent structure includes tight-ly woven,  rip-resistant fabric panels supported by tensile rods or wands, a tub floor extending into and lining a central trench or hole, and an exterior, light-reflecting, metalized, semi-transparent disposable membrane.  The bottom circumferential edge of the outer membrane extends into a shallow trench or-ditch, excavated around the perimeter of the inner tent structure.  Dust particles settling onto the smooth exterior surface of the mem-brane slide off and are captured in the shallow ditch,  thus minimizing direct or indirect radiation into the central trench or hole and its occupants.  The perimeter of the outer membrane contains pockets for the storage of potable water and for anchor-ing of the outer membrane.  The tub floor lining extending below the ground surface includes sealable pockets suitable for the storage of refuse and human waste during occupancy.  Also de-scribed is a light-weight single membrane, plastic, portable tent, suitable for low-cost mass production.

Title: Security devices
Inventor: MARSDEN WAYNE M
IPC: G01F15/00
Filed: 1987-01-27
Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE                      SECURITY DEVICE    A security device for preventing or indicating the tampering with a joint in a supply pipe, e.g. to a gas meter, comprises two or more members which fit together around the joint.   The members have mutually interdigitating parts through which a blind bore is provided and which houses a glass phial containing a dye.   Displacement of the members from-the assembled configuration breaks the phial, thereby releasing the dye which stains the members so that the tampering is readily detectable.

Title: Fast assignment technique for use in a switching arrangement
Inventor: ACAMPORA ANTHONY
IPC: H04L12/64
Filed: 1987-03-09
Granted: 1990-11-27
Abstract: A Fast Assignment Technique For Use In A Switching Arrangement Abstract The present invention relates to a fast packet assignment technique, and a TDMA or FDMA multi-port switching arrangement for implementing such technique.          In the present technique, the total traffic in a two-dimensional traffic matrix (T) from and to each of N remote service areas, regardless of destination or origination, is totaled to form separate input (R) and output (S) traffic vectors, respectively.  Non-conflicting assignments are then made from these vectors for each packet or channel available during a predetermined time period while also providing the capability of substantially reducing multi-path or antenna sidelobe interference.  An MxM switch (16) is designed to implement such technique which directs C input packets from M inputs (201-M) into separate memory locations (Zij).  During the time period of the next C input packets, the MxM switch directs the presently stored packets to the proper ones of M outputs (271-M) at the appropriate time for transmission in the proper packet or channel to the destined remote service areas.          In accordance with the present technique and switch, the M packets concurrently directed from memory to the M output ports can comprise more than one packet from a particular service area to other separate service areas.

Title: Viscous oil recovery method
Inventor: BROWN ALFRED
IPC: E21B49/00
Filed: 1987-11-09
Granted: 1991-04-16
Abstract: VISCOUS OIL RECOVERY METHOD       ABSTRACT Our invention concerns a method for treating a well completed in a subterranean petroleum containing formation which will improve the rate at which steam can be injected into the formation for a steam push-pull or steam drive oil recovery method.  This preconditioning process is applied to formations exhibiting very limited steam receptivity because the formation contains high oil viscosity and has high oil saturation and is completely liquid filled.  The method involves injecting a heated non-condensable and oil soluble gas all in the gaseous phase into the formation at a controlled rate which will avoid permanently fracturing the formation and also avoid the immediate formation of an oil bank due to dissolution of the injected gaseous fluid into the oil.  Ideally by controlling the injection rate, carbon dioxide first displaces water from the flow channels and then slowly dissolves in the oil.  Steam injection can then be applied to the formation without the previously experienced loss in steam injectivity.

Title: Rotary magnetic head device
Inventor: SUWA HISASHI

Title: Contacting thickness gauge for moving sheet material
Inventor: TYPPO PEKKA M
IPC: G01B/
Filed: 1988-07-14
Granted: 1991-04-16
Abstract: Abstract of the Disclosure A  contacting  thickness  gauge  for  measuring  the caliper of paper includes a U-shaped pole piece on one  side  of  the paper with a  return path being provided by a simple ferrite slab on the other side where the magnetic reluctance of the gaps provides a measure of the caliper.  The pole piece has one leg of relatively small diameter contacting the paper; the other larger leg of the U-shaped pole piece being spaced from the paper by either jewel or air bearings to minimize the contact with the sensitive surface of the moving sheet material.  The area ratio provides for an insensitivity of the gap of the large leg.  In addition, the stray self inductance of the windings is  eliminated  due  to  the  use  only  of  a mutual inductance  measurement  to  determine  the  final resonant  frequency which  is  a measurement of the caliper.

Abstract: Abstract of the Disclosure An error recovery system for computers is shown in which an error table and an action table are used to control the parameters of the error recovery system.  The error table has one entry for each possible error and contains a count increment for each corrective action that might be taken to correct that error.  The action table includes an error count threshold for each possible corrective action.  The system operates to accumulate error count increments against possible actions and, when the corresponding threshold is exceeded, initiate the corrective action.  Since the table contents are easily modified, the recovery strategy can be updated and modified by the computer user without changing the recovery system programs.

Granted: 1992-03-24
Abstract: PROCESS OF PREPARING HYDROXYLAPATITE            Abstract of the Disclosure This invention relates to the manufacture of hydroxylapatite in a through-solution process wherein monobasic calcium phosphate is reacted with a calcium hydroxide solution.  In a preferred embodiment, an acidic premix is formed by reacting phosphoric acid and calcium hydroxide with high shear agitation in a first stage, and thereafter reacting the acidic premix with a saturated solution of calcium hydroxide also under high shear agitation in a second stage.  The second stage reaction is carried out in an alkaline solution by carefully metering the acid premix into the calcium hydroxide solution whereby the pH of the solution is maintained above 11 until the reaction is near completion. It is particularly preferred to use a stoichiometric portion of calcium hydroxide in carrying out the reactions.  After the hydroxylapatite precipitate is recovered, it may be sintered at a temperature between about 700°C. and 1100°C. for about 5 to 30 minutes to form a crystalline hydroxylapatite.
