Abstract: The invention is a collapsible transport chair, which comprises an elongated main frame (1) with backrest (4). One end of the main frame is equipped with two wheels while the other end forms a handle (3). An elongated load frame (5), whose one end forms a footrest, is pivotably mounted in the main frame at a distance from the wheel-borne end of the main frame. A support frame fixes the load frame at a predetermined angle to the main frame. One end of the support frame is pivotably mounted in the load frame at a distance from the load frame retainer in the main frame. The other end of the support frame is equipped with locking bodies for releasable locking to the wheel-borne end of the main frame. A seat (12) has a front section that is pivotably mounted in arms (14, 15) while the opposite end is pivotably mounted in the load frame at a distance from the load frame retainer in the main frame. The rear part of the seat is equipped with locking bodies (13) for releasable locking to the main frame. The transport chair's main frame, load frame, support frame, arms and seat can be folded essentially parallel to each other when the seat is collapsed. The seat thereby takes up minimal space in its collapsed state.<IMAGE>

Abstract: A method and an apparatus for the manufacture of heat-exchanger rolls (10). The roll (10) consists of two webs (12, 14) of material which are wound together in superposed relationship. One (12) of the webs is corrugated and formed with protrusions/dents at the crests and bottoms of the corrugations. The second web (14) is provided with lengthwise ribs having the same configuration as the protrusion/dents. When the webs (12, 14) are wound into a roll (10) a radial pressure is exerted on the wheel (10) in order to press the ribs efficiently into the protrusions/dents and to achieve efficient and safe interconnection of the various winding turns making up the roll (10). To impart a tension in said webs (12, 14) a retarding (braking) force is applied thereon during the winding-on of the webs.   The invention also comprises an apparatus for performing the method, the pressure and braking force on said webs being exerted by a pressure roller (56).

Abstract: A solid phase can be coated superficially with a polymeric coating by substituting immobilized metal ions on the surface of the solid phase with a hydrophilic polymer or a derivative or aggregate thereof, through a chemisorption process. The solid phase may comprise a magnetic material, such as magnetite, and may have a particle form. The coating can be produced by bringing the solid phase into contact with a solution of a reagent which includes at least one metal chelating and one reactive group, and subsequently bringing the solid phase into contact with a solution of a compound which reacts with the chelater reagent adsorbed on the solid phase. The polymer layer may constitute a polyhydric alcohol, a polyamine, or a polyamide, for example a polysaccharide, such as agarose, a protein or a peptide, a polyacryl amide, etc. and the reactive group may be a vinylsulphone or an epoxide, an aminothiol or a hydroxyl. The metal-chelate forming group is preferably a carboxy-methylated amine and the soluble compound is a water-soluble polymer, such as dextran, polyethylene glycol, dextran or some other polysaccharide.
Patent SE-8405932-L (SE)
IPC: G05D1/12
Filed: 1984-11-23
Abstract: When a homing head or seeker is mounted on-board a missile, the inertial reference provided by the seeker may be contaminated to some extent by the motion of the missile body. To alleviate this, seekers are sometimes gimballed and use rate or position gyros or they may be momentum-stabilized-the seeker itself providing the inertial reference. However, gyros are both complex and expensive, and momentum-stabilized seekers tend to have large inertias making it difficult to achieve high scan rates. The guidance system described herein allows the establishment of inertial references via information derived from a seeker which need not be isolated from the missile body, the seeker having a range measuring function which, possibly in combination with one or more accelerometers, is used to control pitch, yaw, roll and stabilization of the missile.

Abstract: In an arrangement for transmitting an optical pulse sequence 15, use is made of a laser diode 2 and a control circuit 3 connected thereto. Instead of using homogeneous pulses in the optical pulse sequence 15, a pulse train with two or more part pulses is used for each pulse. These part pulses are brought about by a laser diode 2 being activated and deactivated a number of times during the pulse time t of the homogeneous pulse. The receiver for the transmitted pulse sequence 15 includes a detector 4 and a signal-processing circuit 5. The signal- processing circuit comprises a band-pass filter 18 which allows passage of that part of the frequency spectrum of the optical pulse sequence 16 which has significant amplitudes and has been shifted by virtue of the fact that each pulse in the pulse sequence itself consists of two or more part pulses instead of one homogeneous pulse. <IMAGE>

Abstract: This invention concerns the technical field of digital telecommunications. In particular the invention concerns synchronous and plesiochronous digital hierarchical systems and a method and device for transferring information between such systems. The device according to the invention consists of an asynchronous buffer which separates the SDH system from the PDH system. The data signal entering the buffer DATAin can contain a so-called bit adjustment. In bit adjustment the incoming data signal is contained in a frame with one bit more than nominal or one bit less than nominal. The rate of writing into the buffer varies depending upon whether bit adjustment takes place or not. In order to regulate the rate of reading from the buffer so that it follows the rate of writing, the device comprises a FIFO register in which writing and reading of the data information takes place. For writing write addresses WADR are generated and for reading read addresses RADR are generated. The device comprises an average value calculator 38 which generates average value addresses AVADR around which the write addresses WADR oscillate. If the write addresses WADR as a result of the bit adjustment deviate too much from the average value addresses AVADR then the generation of average value addresses AVADR is hastened or delayed in stages so that the write addresses again oscillate within permitted limits around the average value addresses. The generated average value addresses are used in order to adjust the reading rate.  If the read address deviates too much from the average value address then the reading speed out of the buffer is too high, whereupon the reading is stopped temporarily so that the rate of reading becomes the same as the rate of writing. The device comprises a first phase detector 33 for controlling the average value calculator 38 and a second phase detector 40 for regulating the speed of reading from the FIFO register. <IMAGE>
