Title: Data processing systems
IPC: G06F9/48
Filed: 1974-05-09
Abstract: 1469852 Data processing system SIEMENS AG 9 May 1974 [17 May 1973] 20647/74 Heading G4A [Also in Division H4] In a data processing system in which a plurality of programs having various priorities are executed on the basis of their priority, and in which commands arising during the execution of a program and specifying that a further program having a middle range priority should be executed are stored in a special command list, the priority of the programs specified by the commands in the special list is raised to the highest level of normally occurring programs when the list contains a predetermined number of commands. The arrangement is used in the control of a telephone exchange and three command lists containing commands requesting the execution of associated programs are kept. The highest priority list ZGA contains a number of locations associated with respective devices each of which may contain a command requesting a program ZP, to "time meter" the associated device, a new request from a given device simply overwriting the previous command to obviate problems of overflow. The next list SAL is the special command list containing requests for exchange programe VP1, VP2, .... VPx, occurring as a result of the execution of programs from links ZGA and SAL. The lowest priority list EL contains requests for exchange programs arising from peripheral devices. Normally a cell Y contains the address of an organization program AS which examines the lists in priority order and transfers control to the organization program respective to the appropriate list, viz. ZP, ZPAID and VPA. After the execution of each exchange program from list SAL the list SAL is checked and if it contains more than a predetermined number of commands the address of organization program VPAID is loaded in cell Y so that the commands in list SAL are processed, a return to list ZGA being prevented. The number of commands in list SAL may be examined by a program LVID which is common to all exchange programs or by a priority control device. The predetermined number of commands is determined in accordance with the maximum number of further program requesting commands resulting from the commands in list SAL, e.g. if each command results in at most two further commands and the list has a capacity of 30, the predetermined number is 15 commands. When the list SAL is emptied the cell Y is loaded with the address of program ZP so that all time metering commands, of which a relatively large number will generally have accumulated due to the effective increase in the priority of commands in list SAL above the priority of the metering commands, will be executed without reference to the organization program AS. When the metering commands have been executed cell Y is loaded with the address of program AS and sequencing returns to normal. It is stated that although the commands in list SAL are given the highest priority of normal programs, special programs such as error routines may have an even higher priority.

Title: Continuous process for the fractionation of ternary mixtures
IPC: B01D3/40
Filed: 1963-05-23
Abstract: A liquid mixture of three components A, B and C, in which component C constitutes a major portion of the mixture, is fractionated by introducing the mixture into the head of a distillation column which is heated above the boiling point of component A, whereby a vapour mixture enriched in A passes out of the head of the column, and a mixture of B and C flows out of the lower part of the column.  The mixture, introduced into the head of the column, acts as an entraining agent.  In an example, a mixture of methyl acrylate (7.3%), methanol (15%) and water (77.7%), at a temperature of 54 DEG C., is sprayed into the top of a column which is 9.5 metres high, the lower 4 metres of the column being heated by a jacket to a temperature above the boiling point of methyl acrylate.  The column has no plates or packing.  The vapour passing out of the head of the column is condensed, yielding a distillate containing 78.5% of methyl acrylate, comprising 99.6% of the methyl acrylate in the feed. Aqueous methanol, comprising 94% of the methanol in the feed, is withdrawn from the base of the column.  Another example relates to the separation of ethyl acetate from a mixture of the ester, methanol and water.  The separation of cyclohexane from a mixture of cyclohexane, benzene and aniline, is mentioned.

Title: Improvements in automatic weighing apparatus
IPC: G01G13/00
Filed: 1921-08-10
Abstract: 187,745. Mordle, L. Dare-. Aug. 10. 1921. Automatic-feed weighers. - In an automatic electrically-operated weighing-apparatus such as that described in Specification 171,459 the initial closing movement of the feed shutter is effected by an electromotor with a magnetic clutch in the motor drive. In the form shown in Fig. 1, the feed shutter E (shown in the fully open position), is slowly drawn to the left into the dribble feed position by means of an electric motor G operating through a worm G', worm wheel G<2>, magnetic clutch H and rack G'. The magnetic clutch consists of a number of electromagnets which by magnetic attraction form a driving connection with a disc on the worm wheel shaft. At the dribble feed position a contact arm J' connected to the feed shutter breaks the circuit of the motor G and of the magnetic clutch thus arresting the movement of the feed shutter. When the weight is made up the weigh-beam C tilts and thus energizes a solenoid K which completes the closing movement of the shutter. At the same time a solenoid D<2> is energized to liberate the discharge gate A<1> and the weighed material falls from the weigh-pan. The opening of the shutter E is again effected by a solenoid K<1> and the operation is repeated. In a modification, Fig. 4, a rotary shutter L provided with a series of orifices is arranged beneath the feed sheet F and is rotated first to produce the major opening and partial closing and then to complete the closing. The first of these movements is produced by a motor G and a magnetic clutch H under the control cf fixed contact springs N' and segmental contacts N on the shutter; the second movement is produced by a solenoid P<1> controlled by a contact arm on the weigh-beam, the movement alsore-establishing the circuit at the contacts N, N' to restart the first movement.
