Appl.No PCT/SE1979/000108 Applicant Inventor
A method of simplifying line selection in a telecommunication exchange in which the lines can be seized by this exchange at one end as well as by remote exchange at the other end. The lines which can be primarily selected by said first-mentioned exchange form a first group and the lines which can be primarily selected by the remote exchange form a second group. Upon taking into use the exchanges the lines are selected arbitrarily, which also may comprise random selection among all lines. Upon being identified as idle the lines are stored in a first memory field in the order they have become idle, if they have been selected by the first mentioned exchange, and in a second memory field if they have been selected by the remote exchange. If there are no idle lines in the first field, selection is made in the second field, and after the line selected from the second field has become idle it is stored in the first memory field.

An aspirator for air sampling, the air samples being sucked into a glass vessel for a certain period of time. The aspirator can be carried in a pocket, for example, by the one whose working environment is being analyzed. In a casing there is disposed a replaceable cylinder (2) with associated plunger (4). The plunger is intended to be pulled in by a motor unit (12) and gearbox, arranged adjacent the cylinder (2), the unit (12) rotating a drum (8) onto which is wound a string. The other string end is fixed, via a pulley (7), to the spring-loaded plunger (4). When air has been sucked in to a sufficient amount, the opening (3) of the cylinder is closed and the plunger can be released from the string and the spring, which is possible since the plunger is only magnetically retained (4).

A machine of positive displacement type for the expansion or compression of elastic fluids, wherein torque created or applied effects directly the power shaft, bearings of the power shaft are loaded only by weights of corresponding rotary masses, sealing lubrication is not used and the structure of the machine should accountably facilitate achieving of low losses. The machine includes working spaces (5) defined by a rotary working member (1) and a surrounding body structure (4), and moving circumferentially with the working member, their main direction joining with said circumferential direction. The working spaces (5) are divided into a process space (6) and a transferring space (7) by a partition wall (15) belonging to rotary non-working reacting members (8) which are perpendicular to the working member and synchronized therewith and of so firm structure that they can transmit to the outside of the working member great forces due to a pressure difference between said spaces (6, 7). Said forces can be compensated by a programmed pressure effect onto a counter-surface (11) of the reacting member. Depending on the direction of rotation of the working member either expansion or compression of elastic fluid circulating through the machine is performed. Rotary valves (23) are preferably used for achieving a cyclic closing of the process space (6). A momentary area of the valve opening can essentially correspond to a momentary area of the partition wall (15). A partition wall forming part (10) of the reacting member is preferably provided with only one transition sector (77) for changing the process cycle, whence requirements as to synchronization are low. Light sealing members (110) are preferably used to reduce remaining loss effects due to error in synchronization. Clearances not depending on synchronization may be maintained small by using temperature control of respective parts. A major part of the clearances can be provided with a labyrinth seal (61, 103, 104) for reducing the speed of gas leak.

The process is using iron containing material for heat recovery and heat transfer in the pyrolysis and gasification stages. The iron containing material is simultaneously serving as a chemical reactant by reacting with supplied water or water vapor with formation of hydrogen. The process is carried out in three reaction steps: preheating (1) of the iron containing material, reduction (2) of the iron containing material with supplied solid fuel which is pyrolysed, and oxidation (3) of the iron containing material with water vapor simultaneously with gasification of eventually remaining pyrolysis residues from the reduction step (2) to a product gas containing varying quantities of hydrogen, carbon monoxide, methane, etc. The process has many fields of application from production of an intermediate Btu gas from urban waste to production of hydrogen from bio-fuels. The apparatus consists of several reactor parts with means (22) for transport of the iron containing material from the oxidation step (3) to the preheat step (1) and conduits (7) for transport of pyrolysis gas which remains from the reduction step (2) to the preheat step (1).

In a method of angularly adjusting the position of a building element on a support element, such as a beam (2) on a pillar (1), there is inserted between the mutually facing surfaces of said elements an insert (3) which is operative to transfer pressure from the building element to the support element via an upper surface (3b) in engagement with a lower support surface (2a) on the building element and a lower surface (3a) in engagement with an upper support surface (1a) on the support element. The two support surfaces and the two engagement surfaces are formed in such a manner that, in use, two of the surfaces are planar and mutually parallel, the third surface is planar but not parallel with the two first mentioned surfaces, while the fourth surface is a curved surface generated by a straight line. The curved surface is caused to lie against the non-parallel surface. The insert (3) is rotated about an axis (4) perpendicular to one of the planar surfaces so as to obtain the desired angular position between the building element and the support element with line abutment between the curved surface and the planar surface adjacent thereto. Disadvantages hitherto inherent to the adjustment of building elements on support structures by shimming or packing methods are eliminated, and work at excessive height in connection therewith are avoided. The invention also relates to a support structure and an insert for use therewith.
