Abstract: NHL-KFJ 14 Canada PROCESS AND APPARATUS FOR THE CONVERSION OF WATER          VAPOR WITH COAL OR HYDROCARBON     ABSTRACT OF THE DISCLOSURE      A process and apparatus for conversion of steam and hydro-carbon, or steam and coal, into a product gas which contains hydrogen.  The conversion rate is augmented by effective extraction and removal of hydrogen as and when hydrogen is gener-ated.  Within a reaction vessel wherein the conversion takes place, a chamber for collection of hydrogen is formed by the provision of a hydrogen-permeable membrane.  The chamber is provided with a hydrogen extraction means and houses a support structure, for example, in the form of a mesh providing structural support to the membrane.  The membrane may be of a pleated or corrugated construction, so as to provide an enlarged surface for the membrane to facilitate hydrogen extraction. Also, to further facilitate hydrogen extraction, a hydrogen partial pressure differential is maintained across the membrane, such as, for example, by the counter pressure of an inert gas.  A preferred configuration for the apparatus of the invention is a tubular construction which houses generally tubular hydrogen extraction chambers.

Abstract: Abstract Blood coagulation inhibiting proteins, Processes for preparing them and their uses.            The present invention relates to anticoagulant proteins, referred to as VAC (Vascular Anti Coagulant) proteins which can be isolated from the walls of blood vessels derived from mammals and which do not inactivate the coagulation factors.  These proteins are capable of inhibiting the coagulation induced by a vascular procoagulant or by factor Xa, but cannot inhibit the coagulation induced by thrombin.  They do not inhibit the biological and amidolytic activity of factors Xa and IIa.

Abstract: Abstract of the Disclosure An improved female urinary appliance is disclosed. The appli-ance includes a mouth surrounding a urine-receiving cavity, and a drainage channel integral with the backside of the device and communicates with a bore opening from said cavity.  The device includes means for preventing the drainage channel from kinking.          The mouth is adapted to be positioned within the labia folds of the user, in contact with the vestibular tissue around the meatus and held in place by gentle vacuum.  A valve is preferably used in combination with the appliance, and includes an inlet and an outlet, for maintaining a preselected vacuum condition at the valve inlet and a predetermined pressure condition at the valve outlet is disclosed.  In preferred use, the drainage channel is suitably connected in spaced relation to the valve inlet.  The valve contains a flow control element adapted to control flow of urine from the cavity.  While the mouth is held against the vestibular tissue by gentle vacuum, urine flowing through the appliance and valve entrains gas present in the cavity.  In the cavity, a desired vacuum condition is maintained, over time, because the valve  includes a semi-permeable membrane adapted to permit air and other gas to diffuse through a portion of the valve and thereby to counteract the effects of entrainment and relieve or maintain the vacuum condition at a predetermined level.

Abstract: CONTINUOUS CONTROLLED PROCESS FOR REMOVING    SULPHUR OXIDES GASES FROM STACK GASES             ABSTRACT OF THE DISCLOSURE      A process for effecting the continuous desul-phurization of stack gases includes a double loop computerized system (10) for continuously effecting the desulphurization.  The stack gases are passed through heat   exchangers (14, 15) to raise the temperature to approximately 700°F, the first heat exchanger (14) receiving hot desulphurized exit gas from a reactor (27) and the second heat exchanger (15) receiving preheated SO3 rich flue gases from a catalytic converter (17).  The stack gases heated to 700°F are passed through a preheat burner (16) to increase the temperature to about 850°F and then transmitted through the catalytic converter (17) to convert most of the sulphur dioxide to sulphur trioxide.  The sulphur trioxide rich flue gas is recirculated through the second heat exchanger (15) in order to cool the flue gas, and then fed to the reactor (27) which receives either calcium oxide, calcium carbonate, or both in order to effect SOx removal.  The reaction product(s) is quenched to crack the outer shell of calcium sulphate, and then may be selectively resupplied to the reactor (27) or to storage (21, 51).  A computerized controller (50) responds to a probe (40) to selectively control the supply of the calcium oxide, calcium carbonate, and resupply of reaction products to the reactor (27). Desulphurized exit gas from the reactor (27) passes through the first heat   exchanger (14) for cooling and then through a particle separator (30) before exiting the system (10).

Abstract: DYNAMIC ASSIGNMENT OF AFFINITY FOR VECTOR TASKS        Abstract A method for dynamically assigning and removing task affinity for a resource is disclosed and claimed. A first interrupt handler recognizes a special task interrupt condition which is generated by the hardware. The interrupt condition is generated because a task attempted to execute a special instruction and either a special resource is attached to the central processing unit which issued the special instruction, or a special resource is not attached to the issuing central processing unit, but could be attached to another central processing unit in a central electronic complex.  The first interrupt handler then passes control to a second interrupt handler which determines if execution of the current task can continue.  If it can, the second interrupt handler creates or reestablishes a special environment and the task is dispatched (either for the first time or again) with a special dynamic affinity to only those central processing units in the central electronic complex that have a special resource attached.  Due to the assignment of special affinity the task is dispatched only on a central processing unit with a special resource attached.  The task can be suspended and special affinity removed because of non-use of the special resource over a predetermined period of time. Special affinity is automatically determined following a first-issued special instruction as well as one issued by a task whose special affinity was previously suspended.

A peripheral wall of thermal insulat-ing material extends around the periphery of the base layer and at least one infra-red lamp     extends across the base layer.   A ballast device      is electrically connected in series with the infra-red lamp, for example in the form of a coil of bare resistance wire,  and serves to reduce inrush current to the lamp.  A thermal cut-out device     cuts off the supply of power to the infra-red lamp and to the ballast device      if the temperature of the glass ceramic cooking surface becomes excessive.  The coil of bare resistance wire preferably has an electrical resistance which is approximat-ely half the electrical resistance of the infra-red lamp at its operating temperature.   The use of a ballast device enables the  infra-red lamp      to be used in conjunction with a cyclic energy regulator

Abstract: ABSTRACT     An assay apparatus employing total internal reflection of excitation radiation at the interface between an optically conductive rod or fiber and a surrounding liquid phase of lower index of refraction.  Immobilized on the surface of the fiber is a component of a complex formed in an immunochemical-type reaction; a fluorophore that can be excited into fluorescence by the excitation radiation is attached to another component of the complex.  The fiber is coaxially disposed in cantilevered manner within a length of tubing, so that the excitation radiation can be launched into the unsup-ported end of the fiber and the fluorescent radiation tun-neling back into the fiber may be observed at the same fiber end, thereby preventing that portion of the fiber surface bet-ween the unsupported fiber end and the mounted end being in contact with other than the surrounding liquid phase.
