Title: Data processor control of a plurality of devices
IPC: G06F9/48
Filed: 1973-04-13
Abstract: 1443176 Data processing INTERNATIONAL COMPUTERS Ltd 11 April 1974 [13 April 1973] 17865/73 Heading G4A In a data processing system a system manager program 10, when in control of the processor, issues commands to device manager programs 11, 12, and when control has been passed to a device manager for execution of a command the device manager supervises the operation of an associated one or more peripheral devices and control is passed from each device manager to the next in a predetermined cyclic sequence without return to the system manager until one of the device managers detects that execution of a command issued to it has been terminated. Control may be passed between device managers by including in each the start address of the next manager in the sequence, but immediate return to the system manager after setting-up a command may be caused by including a qualifier bit in the command code. Alternatively control may be passed between device managers using a table of device manager start addresses accessed sequentially by the device managers, the table being set up by the system manager or other software. The system manager 10 issues a command to a device manager 11, 12 by causing a jump to the entry point of the device manager and storing the command code and a return link address in two reserved registers. A device manager returns control to the system manager, when execution of its command has been terminated, by adding 0, 4 8 or 12 to the link address, depending on the the reason for the return, the modified link address storing a GO TO instruction pointing to the appropriate system manager routine. Device managers include a routine for each command: TRANSFER (specified number of characters into specified buffer area), DEMAND STATUS (software state of device manager and address of a first word in a set indicating the hardware state of the peripheral to be transferred to the system manager), SET MODE (set or unset peripheral in autonomous or slave mode), DEALLOCATE (disconnect peripheral from processor), RESET; and a MONITOR routine which checks for conditions requiring return to the system manager. Normal level operations round the device manager sequence loop 20 are interspersed with interrupt operations concerned with transfer of characters between peripherals and the buffer area. Each device manager may also enter the system manager as a conceptual routine, e.g. to cause print-out of a message at an operator console to indicate that a particular peripheral device should be connected into the system, the console being treated as a peripheral device and having its own device manager program in the sequence loop 20.

[Also in Division F2] A thermoplastic plastics profiled strip 1, comprising at least one longitudinally extending protrusion 3 and at least one longitudinally extending groove 2 for engagement with the protrusion at, the protrusion of another identical strip, is characterised in that the crosssections of the protrusion and groove are non- identical and are such that, when the protrusion is in interengagement with the groove, the protrusion causes the groove to be enlarged and the groove causes the protrusion to be diminished whereby the groove and the protrusion are urged towards one another over substantially their entire surfaces. The strip may have a reinforcing rib 6 which may be hollow and receive a tube of different plastics material or a wire, or cord of metal or plastics material. Alternatively, a hollow rib 6 may be filled e.g. with glass fibres. In a modification, Fig. 4 not shown, a groove (2) of dovetail shape is formed inwardly of one side edge of the strip (1) the web (3), tapering outwardly, projecting laterally from the opposite side edge. The strip may be of considerable thickness and include longitudinally-extending channels for carrying media or accommodating other materials. The joint between the web 3 and groove 2 may have an intermediate layer e.g. of rubber soft P.V.C., polytetrafluoroethylene &c., or fabric. In a modification; Fig. 9, several thicknesses of strip may be intergaged by providing each strip with grooves 2 on one face and webs 3 on the other, the joins being preferably relatively offset from layer to layer. The notch 12, Fig. 2, can be avoided by providing a ledge on the inside of the web 3 to received a shortened outer limb of the groove portion, Fig. 11 not shown.

Abstract: 1,129,738. Change-speed gear; clutches. FORD MOTOR CO. Ltd. 20 April, 1967 [2 May, 1966], No. 18151/67. Headings F2C, F2D and F2L. In a change-speed gear for a motor vehicle wherein steps 68, 72 ... 78, of a countershaft gear cluster 70 respectively mesh an input gear 66, intermediate and low gears 90, 92, a reverse gear 94 through an idler 96 and an overdrive gear 106, the gears 66, 90, 92, 94, 106 are selectively connected to an output shaft 24 by an axially movable sleeve 114 having external splines 120, 122 engageable with internal splines 124 ... 130 in the gears and the sleeve 114 is connected to the output shaft by a friction clutch 174. The friction discs 170, 172 of the clutch 174 are respectively splined to a hub 134 rotatably fast with the sleeve 114 and to a back plate 168 rotatably fast with the output shaft 24. The discs are urged into light frictional engagement between the back plate 168 and a presser plate 180 by a spring 198. Rollers 192 carried by the back plate 168 engage cam recesses 190 in a cam plate 182 fast with the presser plate 180 to provide a torque responsive axial engaging force on the clutch discs. The clutch is disengaged by supplying pressure liquid from a manually operated master cylinder 236 to an annular slave cylinder 230, the piston 224 of which acts through a thrust bearing 191 to move a clutch release ring 188 left. Cam recesses 186 on the ring 188 co-operate with complementary projections on the cam plate 182 to rotate the latter to a position in which the rollers 192 are in the deepest part of the cam recesses 190 and thus relieves the clutch of torque responsive loading. A shift sleeve 144 splined to the output shaft 24 and to the hub 164 of the back plate 168 is located in the gear ratio and neutral positions by a ball detent 151 and is locked in these positions whilst the clutch is engaged by a ball 208 which cooperates with the clutch release ring 188. For ratio shift the clutch is disengaged and the leftward movement of the ring 188 frees the locking ball 208 to permit conjoint axial ratio shifting movement of the sleeve 114 and the shift sleeve 144 by a shift rod 244. On completion of ratio shift the clutch is re-engaged and ring 188 automatically locks the shift sleeve in its new position. Balls 146 connect the sleeves 114, 144 for conjoint axial movement whilst permitting relative rotation. Three equally spaced gear clusters 70 support the gears 90, 92, 94, 106 without bearings. The gears have double helical teeth to avoid axial thrusts.

The invention provides a telegraph switching system wherein normal traffic can be interrupted temporarily by a station having greater priority. Normal transmission takes place over a fourwire line between two stations, but when a priority signal is received from a booking station (e.g. a passenger seat booking office) switching operations are initiated to switch off the normal transmitters and receivers and to bring in circuit the central booking office. Booking data is then transmitted over the four wire line, followed by a release signal which causes the normal transmitters and receivers to be brought back to operation. It is arranged that switchover to the priority system can not occur until after the transmission of a complete code combination, so that such a combination is not received mutilated.
