Abstract: ABSTRACT OF THE DISCLOSURE            A process to produce pulp from vegetable, cellulose-containing fibrous material such as coniferous wood, hard-wood, straw and bagasse, the fibrous material being treated in several stages.  In a first stage the fibrous material is impregnated with a solution of sodium hydroxide, in which solution the material is soaked and partly disintegrated by mechanical working.  In a second stage excess of alkaline solution is squeezed out to such extent that the content of sodium hydroxide in the raw pulp amounts to at least 15 kgs per BD ton of pulp.  In a third stage the pulp material is subjected to additional disintegration under supply of a solu-tion of sodium carbonate so that a pumpable pulp suspension having a sodium carbonate content of 150-400 kgs per BD ton of pulp is obtained.  In a fourth stage the pulp suspension is subjected to a cooking process at a temperature of at least 100°C for 1-4 hours and with stirring and a supply of oxygen, whereupon the cooked pulp is washed.

Title: Conductive fluid detecting method and apparatus
Inventor: STENSTROM STEPHEN M
IPC: G01F23/70
Filed: 1981-12-23
Granted: 1984-04-17
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a method of detecting the presence of a conductive fluid such as water in a chamber such as the oil pan of an internal combustion engine and apparatus for carrying out the method.  A resilient flexible sensor probe is mounted in the oil drain and electrically connected to an alarm which is activated by current flow.  The sensor probe has an outer electrode member with a portion formed of a helical coil through which an insulated wire runs to form an inner electrode member.  The inner electrode member is connected to the alarm, while the outer electrode member is grounded to the engine.  The sensor probe bends to a position where its inner end portion depends into contact with the bottom of the oil pan.  The inner electrode member ends at a bare tip which is surrounded by an insulative sleeve which prevents direct contact with the bottom of the oil pan.  The outer electrode member ends at a bare wire portion which is spaced a short distance from the tip of the inner electrode member.  When the tip of the inner electrode member is covered by water, the circuit is completed either through the outer electrode or directly to the oil pan, and the warning alarm is activated. This dependent resilient flexible sensor probe structure has the advantage that the build up of insulative sludge is avoided by the constant motion of the inner end portion due to flexing of the sensor probe as a result of engine motion, as well as by relative longitudinal motion between the inner ends of the electrode members.  Another advantage is that the inner end portion of the sensor probe contacts the bottom of the oil pan at its lowest point.

Abstract: ABSTRACT     Re-enterable Closure Assembly A re-enterable closure assembly for enclosing an elongate substrate such as a telephone or power cable, has an outer sleeve, preferably heat recoverable, and an inner liner to protect the cable against heat and mechanical damage. The liner has two major parts, a support and a disposable layer, thus allowing the outer sleeve to be removed, for repair etc, without damaging the liner. This could not easily be achieved in a one piece liner since a bond generally must be formed between the liner and the outer sleeve to prevent wicking of moisture vapour.

The spider in-cludes a central support arm extending diametrically across the convoluted center of the heating element generally aligned between and parallel to the terminal legs of the heating element.  The end of the central arm adjacent the legs is laterally directed to form an abutment against which the vertical portion of the outer of the terminal legs engages.  The heating element, beyond the convoluted central portion, includes a connector having apertures for receiving the terminal inner and outer legs therethrough.  The connector includes a boss affixed thereto surrounding the aperture receiving the inner leg, which boss is crimped to the inner leg for a positive mounting of the connector.  The outer leg is freely received through its corresponding aperture, the connector limiting lateral movement of the outer leg relative to the inner leg. Longitudinally inward movement of the outer leg is limited by the abutment defined on the support spider arm.  The support spider is assembled to the tubular heating element by a bracket which includes a sleeve about the terminal end portion of the inner leg, and a vertical panel including a lateral offset and a vertical flange which is affixed to the overlying central arm of the spider.

Abstract: STORAGE FETCH PROTECT OVERRIDE CONTROLS     Abstract This invention relates to the fetch protection of a critical area in the main storage (MS) of a data processing system.  The critical area is smaller than, and contained within, the size of a main storage block protectable by a single storage protect key having a fetch protection field.      This invention extends protect key operations for system/370 extended architectures that use 4KB pages.  This invention recognizes that system integrity is enhanced by providing different types of fetch protection within the PSA page which cannot be done with the associated 4KB key.      To enable different fetch protections within a special 4KB block, this invention provides fetch protect override controls to partly override the normal operation of the 4KB storage key for a page located at a predetermined real address in MS.  While 4KB fetch protection is set on for the special page's 4KB block, the fetch protect override controls disable fetch protection for a portion of the special page's real addresses (e.g. addresses 0-2047).      Override enablement is controlled by a fetch protect override control bit in a control register (e.g. bit 6 of control register 0).

Abstract: ABSTRACT OF THE DISCLOSURE          A radial fan comprises a spiral-shaped fan housing and a drum-shaped wheel which rotates in the direction which the spiral increases and has an opening  facing  towards  an intake in the end wall of the housing.  The area of the duct formed by  the  housing  and  the  periphery  of  the  wheel increases  continuously  from  a  point   where   the   duct cross-section is smallest up to an  outlet  part  where  the cross-section is greatest and where the  area  is  at  least equal to the radius of the  wheel  times  its  length.   The intake is made eccentric by a guide vane  installed  at  the opening and extending near the inside of  the  wheel  by  an edge part located after the  said  point,  cutting  off  the cross-section of the duct outwardly of the outer end of  the wheel.  The rear face of the guide vane  and  the  end  wall form an inwardly facing  flow  surface  which  extends  over approximately half the periphery of the  wheel.   The  wheel length is approximately two thirds or more of  the  internal axial dimension of the housing, and is  approximately  equal to the radius of the wheel.
