Patent GB-1423409-A (GB)
Title: Input/output system for a microprogramme digital computer
IPC: G06F13/12
Filed: 1973-07-17
Abstract: 1423409 I/O control BURROUGHS CORP 17 July 1973 [12 Jan 1973] 33955/73 Heading G4A Each I/O cycle is divided into two phases A, B which are initiated by Command Active and Response Receive micro-operators read from a control memory in the processor. An I/O interface is controlled by the micro-operators to transmit corresponding command active (CA) and response complete (RC) signals over the I/O bus together with commands to control the data transfer between a selected processor register and I/O control unit. During phase A of a transfer out command (XFROT), the command type and channel address are sent to the I/O control units from the interface, and the addressed unit responds in phase B by returning the contents of its status register 50. Successive XFROT commands are used to load the OP code of the descriptor and a file address (3 bytes each) into registers 76 and 82, register 50 being advanced up to state STC-6. For a read operation, the interface supplies a reference address from the descriptor for loading into buffer 52 (STC-7 to STC-9). During SCT-10 data transfer from the associated peripheral device takes place serially by bit, bytes being assembled in register 54 and transferred to buffer 52. On completion of the transfer (STC-11), a service request signal SR is returned to the interface, and successive transfer in commands XFRIN are used to cause return of the reference address (STC-11 to STC-13) followed by successive data bytes (STC-15) until a flag indicating the last data byte is detected, or a terminate command TERM is sent by the interface. Finally, further XFRIN commands cause the contents of the result descriptor register 90 to be transmitted to the interface. The data transmitted to the processor during phase B of each XFRIN command is accompanied by the current status count. A write operation is similar except that the reference address is loaded into buffer 52 after the data supplied by the processor and is returned to the processor, after the data has been transferred to the peripheral device, in response to XFRIN commands supplied as a result of the SR signal generated by the control unit. The status of a selected I/O control unit can be tested at any time by a test status or clear and test status command, the response during phase B including the status count, the type of peripheral associated with the addressed control unit, and a "power on" indication. A test service request command can be applied to all the I/O control units, those requiring service being identified by corresponding bits set in a mask register 73 the contents of which are returned during phase B of the command.

Title: Digital data copy duplication method and apparatus utilising bit to bit data verification
IPC: G06F3/06
Filed: 1973-07-18
Abstract: 1394918 Digital tape verification BURROUGHS CORP 18 July 1973 [18 Sept 1972] 34221/73 Heading G4C An arrangement for verifying digital data copied on to a slave record from a master record includes means for writing in to the slave digital data and associated clock signals while the data and clock signals are being read from the master. The data and clock signals are read from the slave while writing is taking place, and the data is compared, bit for bit, with the corresponding data read from the master, the comparison taking place while data and clock signals are being read from the master and written in to the slave. The embodiment described verifies the data from a magnetic master record with the data on each of a number of magnetic slave records. Data and clock signals are read from the multitrack master (11, Fig. 1, not shown), and pass via a synchronizing unit (13) and slave drive (15) to each of N slave records (21-25). The synchronizing unit operates in known manner to control the speed of the master record (11) according to the difference of the write-in and read-out data rates of a store in the synchronizer. Each of the T data tracks of the N verifiers is associated with a respective verifier. One such is shown in Fig. 2. Data from one track of the master, received via the synchronizing unit (13), is fed over lead 63 to random access memory 73 which also receives clock signals from the master. These clock signals have a phase #1. Before the next data bit is read in to memory 73 the bit just read-in is read-out over line 97 when a clock pulse of phase #2 occurs. The bit readout is compared at 75 with the bit read-in, and an error indicated if they do not agree. Data read from the slave track is written in to one-bit buffer 83 under the control of #1 clock pulses read from the slave. Prior to writing the next bit in to buffer 83 it is read-out, under the control of a clock pulse of phase #3, to comparator 85 where it is compared with the corresponding bit read from memory 73 and an error is indicated if they do not agree. The address to which a bit is assigned in memory 73 is indicated by a write counter 79 which is incremented by the #1 clock pulses from the master record. Similarly the address of the stored bit to be compared with the bit from buffer 83 is indicated by read counter 81 incremented by the #1 clock pulses from the slave record. When the slave record has been completely verified the outputs of the counters 79, 81 are compared and an error indicated if they are unequal.

Abstract: 348,663. Trimming timber. SÍRENSEN, E. F., 11, Blasieholmstorg, Stockholm, and SÍRENSEN, N. E. E., Sõvenõs, Gothenburg, both in Sweden. Nov. 18, 1929, No. 35225. [Class 145 (ii).] In an edge-trimming machine for timber the position of the timber before being fed to the cutters is adjusted under the control of an inverted facsimile of the edge to be trimmed, which facsimile is constituted by a set of points 9, the position of which is determined by feelers 8 which are moved into contact with the edge to be trimmed by a cam-operated rocking arm 30. In the machine illustrated a second set of points 11 controlled by feelers 10 is provided for use with timber having an inclined face. The two points of the facsimile furthest advanced (90<1> and 90<11> in Fig. 4) limit the position of a straightedge 13 which is moved by a weight 17, the ends being carried in trucks 14, and the motion of the straightedge adjusts the position of two levers 191, 19<11>, which are then locked by the action of cam-shaped members 70<11>, 74<11>, the latter mounted on the shaft 21<11> carrying the levers. A cross rod 26 carrying arms 27<1>, 27<11> which grip the timber, is then moved, by springs 370 and levers 35 under the control of cams 36, to an extent determined by the position of the lower ends of the levers 19<1>, 19<11>, so as to set the timber, whereupon one of the arms 27<11> is moved aside by means of a cam-plate 69, to permit the timber to be fed to the cutter 1. In a modified arrangement (not shown) the adjusting movement of the timber is arranged to take place in the opposite direction. In a further modification, illustrated in Fig. 6, the feelers 80, 100 are formed on rods 130, 140 carried in a frame 47 which is arranged to be adjusted, along with the timber gripped by arms 27<1>, until further points 90, 111 on the rods 130, 140 meet a stationary straightedge 130<1>, 130<11>. Specifications 239,892, 245,310, and 257,095, [all in Class 145 (ii), Wood, Working], are referred to.

Abstract: 1478080 Sampling liquid metal INTERATOM INTERNATIONALE ATOMREAKTORBAU GmbH 26 Aug 1975 [11 Sept 1974] 35270/75 Heading G1B In a device for obtaining liquid metal samples from a circuit, liquid metal flows upwardly through a duct 4 and is deflected by a concave baffle surface 34 at the base of an insert 31 and directed into the crucibles 23. The baffle surface 34 is concentric with the duct 4 and is provided with a discontinuity edge 35. Crucibles 23 are contained within an annular zone 47 concentric with the duct 4 and the discontinuity edge 35 is arranged radially around the outer portion of the zone. The crucibles 23 are disposed in supporting means 36 supported by supports 38 which in turn, are held by the insert 31. In supports 38, the wires of thermocouples 28 extend and are connected to the supporting means 36. A thermocouple can also be arranged in a central, downwardly projecting spike-element 48 of the insert 31; the element 48 extends into the upwardly opening mouth of the duct 4. The housing part 30 comprises an upper and lower portion connected by bolts 41. Liquid metal flows into the device via duct 4 and is deflected into crucibles 23 with excess metal flowing away via outlet 24, owing to the shape of faces 34, 44 and 45, ensuring that all excess metal is discharged from housing 30. Insert 31 with crucibles 23 can then be removed from the device and thereafter liquid metal distilled off from the crucibles and the residues remaining in the crucibles analyzed. Alternatively the metal may be distilled off in the device itself by a heating means 27 spirally wound around housing 30.
