Abstract: Abstract of the Disclosure METHOD FOR MAKING AIRSPRING FLEX MEMBERS   A method of manufacturing a beadless flexible member for an airspring having a fully molded non-tubular shape.  An axially segmented mold with tapered circular end bores is used with conically tapered end plugs which sealingly compress an uncured preform of the flexible member between the conical plugs and the tapered circular end bores.  Compressed fluid is injected into the interior of the preform to radially expand it to the desired molded shape. At a rate determined by the radial expansion of the preform, the annular segments of the mold are axially moved together to accommodate the axial foreshortening of the preform during its radial expansion.  After full axial closure of the mold, heat and pressure are applied to vulcanize the preform.  The beadless, fully molded flexible member may be used for airsprings requiring zero pressure roll capability.  Preferred forms of the flexible member have tapered wall thickness in the neck with circumferential indexing ribs for exact placement of compression rings on the finished airspring.

Abstract: A DIRECT COUPLED CHARGE INJECTION READOUT CIRCUIT AND READOUT METHOD FOR AN IR SENSING CHARGE INJECTION DEVICE        ABSTRACT OF THE INVENTION   The invention relates to an improved readout circuit and  readout method  for  an  IR sensing  array.   The invention, given a limited time interval for reading out the signal from a sensor element in an array of sensor elements, permits a longer time to be devoted to the injection  of  charges  into  the  substrate,  thereby reducing  device  "lag"  (the  retention  of  uninjected charges).  The readout is carried out by a two step, direct  coupled,  injection process.   The  first step involves independent, but simultaneous resetting of the sensor elements and the preamplifier input  (at a node having  sufficient  capacity  to  supply  the  charges required for injection).   The voltages are suitable for IR induced charge storage in the sensor elements,  and for subsequent injection by the nodal capacity.  A first sample is taken by a correlated double sampling circuit from the preamplifier output during the first step as the  resetting  stabilizes.   In  the  second step,  the selected sensor element is connected to the preamplifier input to cause the charge injection.   At the same time the preamplifier is responding to the charge transfer.          The second sample is taken from the preamplifier output at  the  end  of  injection.   The reduction in lag over conventional AC coupled readout circuits is 80%.

Abstract: In the present invention, hydrated magnesium salts of the carboxylate group in certain aromatic or olefinically unsaturated peroxyacids such as monoperoxyphthalic acid or monoperoxymaleic acid are made by reacting the corresponding anhydride with aqueous hydrogen peroxide and a magnesium base, in the absence of a significant amount of free iron. By so doing, the process avoids the use of non-aqueous solvents such as ethyl acetate. Solid product can be obtained by using no more than enough hydrogen peroxide and water for solely a damp product to be obtained or by crystallization from an aqueous solution, preferably with recycle of the mother liquor. Preferably the reaction temperature is maintained at 5 DEG  to 25 DEG  C., employing 1.8 to 2.2 moles anhyhdride per mole of magnesium base, and 0.95 to 1.2 moles of hydrogen peroxide per mole of anhydride. The product can be used as a bleach and as a disinfectant.

Abstract: In a data processing system, two instruction sequences are executed in an order determined in advance. The execution comprises selecting read/write addresses with read/write instructions 4, in which way a main memory 1 common to both sequences is activated for data information reading/writing. During execution of the second sequence in the order, use is made of data information with regard to which it has not been ensured in advance that it is independent of the data information which is produced during the execution of the first sequence in the order. Increased data handling capacity is achieved in the following manner: both sequences 5 are executed in parallel to start with. During execution of the first sequence, the main memory is prevented from being activated for writing due to second sequence write instructions 37, 39, 41. A write address and data information included in a write instruction 49, 50 associated with the second sequence are intermediately stored. The intermediately stored write address is compared with read addresses 68, 70, 73 in the second sequence, data information being prevented from being read from the main memory in response to an identity of the addresses, and the intermediately stored data information  37, 38, 39, 41, 44 being read instead. An address included in a read instruction associated with the second sequence is intermediately stored if this address has not previously been selected in conjunction with a write instruction 49, 50 associated with the second sequence. The intermediately stored read address is compared with write addresses in the first sequence, and execution of the second sequence 66, 74, 76 is restarted in response to an identity of the addresses. When execution of the first sequence is complete, the intermediately stored data information is transferred by means of the intermediately stored write address to the main memory 38, 46, 78, 79. <IMAGE>
