Title: Digital data processing apparatus
IPC: G06F13/36
Filed: 1975-04-08
Abstract: 1494694 I/O systems INTERNATIONAL BUSINESS MACHINES CORP 8 April 1975 [26 June 1974] 14310/75 Heading G4A Two internal buses of a central processor are connected via gates 38, 40 to a bidirectional I/O bus containing data and control lines, enabling of the gates and transfer of I/O requests, addresses, commands and data over the I/O bus being controlled by an I/O port control subsystem. In the described embodiment, communication between the central processor and I/O devices is via adaptors and an adaptor control block 54 which conducts the handshaking dialogue between the adaptors and the central processor. I/O interrupt requests are held in latches 76 and are gated on to the I/O bus when the latter is not required for transmission of data, addresses or commands. The highest level of interrupt present is determined by a priority resolving network 36 which then invokes a software routine appropriate to that level to poll the devices assigned to it. A special adaptor may be used when a plurality of devices attached to it share the same interrupt level. For a read or write I/O operation the device address and the appropriate command are transmitted over the I/O bus from a memory location specified by the I/O instruction, the address and command being sent simultaneously or successively depending on whether the adaptor is capable of receiving two bytes (half word) or a single byte only at a time. Transmission of one or two bytes of data between the addressed device and a specified memory location then follows and on completion of the I/O operation interrupt requests may be returned to the I/O bus. Cycle steal requests to transfer lengthy chains of data are initiated by the requesting adaptor transmitting a CS request and a control word containing a read/write command, memory starting address and byte identifier. The control word is placed on the I/O bus when the processor signals that it has completed execution of the current instruction. The start address is stored and updated by one or two for each transfer until the EOC tag is raised to indicate end of chain. The I/O port control subsystem includes a read-only control store 46 for sequencing the programmed I/O and CS operations using microprograms appropriate to the different operations required. Failure of an adaptor to respond within a preset time to signals sent over the tag lines may initiate a machine check sequence.

Title: Improvements in or relating to vehicle suspension systems
Inventor: JAMPIETRO ACHILLES CHARLES
IPC: B60G17/04
Filed: 1960-04-28
Abstract: 942,666. Hydropneumatic suspensions. THOMPSON RAMO WOOLDRIDGE Inc. April 28, 1960, No. 14990/60. Heading B7D. A vehicle has a frame 10, Fig. 1, and a rear axle 17, hydropneumatic springs 20c, 20d between the frame and axle and comprising a body of gas 30, Fig. 4, compressed by fluid under pressure, a source 31 of fluid under pressure, a levelling valve 33 to connect the source to the springs on downward movement of the frame and to relieve the pressure on the springs on upward movement of the frame, and an hydraulic valve 60 actuated by braking pressure to increase the pressure in the front springs upon application of the brakes. The front wheels are independently suspended on arms 15, 16 and a further pair of hydro-pneumatic springs 20a, 20b controlled by a separate levelling valve 32 and in which the pressure is increased upon application of the brakes. Roll stabilizer bars 44, 45 connect the front and rear wheels and carry levers 42, 43 for operation of the levelling valves through a resilient bush, such as that shown at 55, Fig. 3, to prevent the valves from responding to instantaneous road shocks. Tubes of smaller bore, such as 40a and 41a, Fig. 4, may also be used in the fluid pressure circuits to delay the response of the system. The upper end of each spring has a pivotal connection with the vehicle frame and contains a piston 28 separating the gas from the fluid under pressure. A partition with an aperture 29 on a control valve provides a dashpot effect for each spring. When the front or rear wheels move upwardly or downwardly together, their springs are connected by the appropriate levelling valve to conduits leading to the source 31 of fluid under pressure on a sump 36. When the brakes are applied with sufficient pressure to overcome the resistance of a spring 69a and the pressure in a chamber 76 communicating with the front springs, the spool 65, Fig. 4, of the valve 60 is moved to the right to connect the front springs with a conduit 61 leading to the source 31 and the rear springs to a conduit 64 leading to the sump 36 so that the front of the vehicle is lifted slightly. Solenoid-operated valves 80 are closed by a pressure-responsive switch 86 when the brakes are applied to isolate the levelling valves from the springs and are also controlled by the ignition switch 85 to prevent actuation of the levelling system when the vehicle is parked.
