Abstract: 1,245,052. Preparing 0,0-dialkyl thionophosphoric acid chloride. KNAPSACK A.G. 3 Oct., 1969 [5 Oct., 1968], No. 48666/69. Heading C2C. An O,O-dialkyl thionophosphoric acid chloride in which the alkyl groups are C 1 -C 6  is obtained by reacting an appropriate dialkyldithiophosphoric acid with chlorine, the chlorine being added to the O,O-dialkyl dithiophosphoric acid, which is generally stirred under an inert gas at a temperature lower than about 75 C., and following the completion of the chlorine addition adding to the reaction mixture a further portion of O,O-dialkyldithiophosphoric acid at a temperature between 0 and 75 C. and distilling the reaction mixture, preferably under vacuum to isolate the O,O-dialkylthionophosphoric acid product. The distillation residue is preferably freed from precipitated sulphur and then used again as additional feed material for the reaction of a further amount of O,O-dialkyldithiophosphoric acid with the chlorine. In operation three moles of chlorine are suitably introduced into 2 moles of the O,O-dialkyldithiophosphoric acid and a further mole of the latter then added. After adding all the chlorine it is desirable to cool the reaction mixture to room temperature prior to adding the further quantity of thiophosphoric acid diester. O,O-dimethyl- and O,O-diethyldithiophosphoric acid are obtained by reacting P 2 S 5  with methanol and ethanol respectively at between 45 C. and 65 C.

Abstract: 1,149,779. Magnetic printing. W. C. HELLER. 9 Nov., 1966 [9 Nov., 1965 (2)], No. 50219/66. Heading B6C. [Also in Division H1] The energization of a magnetic circuit comprising polepieces 5, 17, Fig. 1, causes a magnetic flux to pass through the gap 7 between the poles in which a magnetic image member 4, a non-magnetic material 8, a rotating disc shutter device 9 and a magnetic particle carrier box 13 are disposed. The flux causes the magnetic particles to adhere to the underside of the material 8 the image created by the adhesion depending upon the imagery of the member 4. The disc shutter device masks the material 8 only allowing passage of particles through the relevant shutter hole 9a. The material 8 is so chosen that the particles are caused to adhere to the underside thereof through lodgement within the interstices of the material. A milk bottle 82, Fig. 14, is imprinted through the development of a temporary magnetic particle image on the bottle facing side of a slidable carrier 83 which closes upon the bottle causing presentation thereto of the image. Adhesion is effected either by heat or through the application of adhesive to the bottle prior to printing. The particles may be heat fused to a glass bottle or, if the bottle is thermoplastic, through heat softening of the bottle walls. The non-magnetic material 8 may be polytetrafluoroethylene, polytetrafluoroethylenecoated, or silicone rubber, or resin-coated fibreglass. Other materials are natural, styrenebutadiene, nitrile or neoprene rubber or P.V.C. or polyurethane. Magnetic materials for use in making the magnet or cores and the magnetizable or magnetic particles can be any magnetic material known in the art. Examples are iron, cobalt and nickel and their alloys such as a 35 Co-65 Fe alloy; silicon steel; low carbon cast steel; high carbon cast iron; tungsten steel; ferrites such as barium ferrite, manganese zinc (or magnesium) ferrite.

Title: Data processing apparatus
IPC: G06F9/48
Filed: 1977-12-09
Abstract: In a multi-programmable data processing system, devices and measures are provided for checking, after execution of a program called up by an interrupt, whether in the meantime another interrupt request of the same type (for example input/output interrupt) has occurred so that the latter can then be served during the interrupt program which is still active. In this manner, the execution of interrupt routines of the same type can be concatenated with one another which saves data exchange processes between processor and memory which otherwise are required at the beginning and end of each interrupt. For the data processing system, a special command "interrogation for waiting interrupt request" (TPI) is provided which can be placed at the end of each interrupt routine and when this is decoded, the interrogation for waiting interrupt requests, the setting of a conditional code and the storing of an interrupt code and a branch back in the relevant program for dealing with the interrupt request found are effected via special signal lines. <IMAGE>
