Title: Memory control apparatus adaptive to different access and cycle times
IPC: G06F13/42
Filed: 1973-04-04
Abstract: 1415233 Control apparatus HONEYWELL INFORMATION SYSTEMS Inc 4 April 1973 [6 April 1972] 16222/73 Heading G4A A data processing system comprising at least one data processor (7, Fig. 1, not shown) and at least one memory (9, 39) also includes means for providing an initiate request signal (MEMCIN) when the processor has provided a memory address signal for storage in a register (13) and means for generating a data ready signal (MDTRDY) when the address location has been written into or read from, the memory cycle being terminated after processing of the stored information. The memories may have different access and cycle times. In one embodiment (Fig. 2) flip-flop 40 generates the request signal which, if the memory is not busy, passes AND gate 10 to set flip-flop 26 to generate an acknowledge signal. Either the memory or one shot multivibrator 12 then generate a memory busy signal for a duration corresponding to the memory cycle time less propagation delays. After a time determined by a delay 16, gate 22 is enabled to set flip-flop 24 to generate a signal which via a gate 42 resets flip-flop 40. This signal is also coupled to gates (23, 27, Fig. 1, not shown) to either clear a data register for a read operation or enable if for a write operation. When transfer of data has occurred (that is after a time dependent on the access time of the memory) the signal MDTRDY is generated to reset bi-stable 26 and enable gates 32 so that, after a delay of 160n sees. if the addressed instruction requires a short execution time, signal ETA passes gate 54 to set the flip-flop 40 or, if the instruction requires a long execution time, after a further delay of 120n sees. signal ETB passes gate 56 to control the flip-flop. The signal ETA, ETB are derived by comparing the accessed instruction with categories of instructions. When the processor detects the next cycle is to be a non- memory cycle it generates a signal NMC which inhibits gates in the control apparatus and a fixed-length non-memory cycle is executed. In a second embodiment (Fig. 4, not shown) the setting of the flip-flop (40) is controlled by a gate (71) primed by the non-memory cycle signal (NMC). A flip-flop (24) is set via an AND gate (72) for each memory cycle it being reset via an AND gate (32) and delay (50) after a fixed time. A second processor may be connected to the controller via further AND gates (10<SP>1</SP>) coupled via gates (74, 76), controlled by priority logic to flip-flops (26, 26<SP>1</SP>).

Abstract: 1422010 Recirculating IC engine exhaust GENERAL MOTORS CORP 5 April 1973 [19 April 1972] 16284/73 Heading F1B [Also in Divisions F2 and G3]  An exhaust gas recirculation control valve assembly of an I.C. engine comprises a valve seat 76 in a recirculation passage having an inlet 60 and outlet 64, a valve member 82 co-operable with the valve seat, a pressure responsive member 102 operable to position the valve members relative to  its seat, and a passage 92 for subjecting the pressure responsive member to the pressure upstream of the valve seat in a chamber 104.

Title: Operating mechanism for a motor vehicle
IPC: B60T11/10
Filed: 1974-04-11
Abstract: 1471421 Pedals for brakes and motor-control C M ZWERENZ 11 April 1974 16299/74 Heading B7H A motor vehicle control comprises a combined accelerator and brake pedal, and an actuating arrangement utilizing a source of power other than or in addition to the drivers foot to produce a motor idling condition when the pedal is moved to the brake-operating position. As shown in Figs. 3 and 5 a first lever part 1<SP>11</SP> is pivotable about a pivot 4 to operate the speed control, while the lever 1 as a whole is pivotable about a pivot 3 at right angles to operate the brake. Clockwise movement of lever part 1<SP>11</SP> away from contact 12a closes a limit switch 12, while forward movement of the whole lever 1 closes a limit switch 11, these closures effecting energization of a solenoid 14 which operates a Bowden cable system 6 to restore lever part 1<SP>11</SP> to the idling position. In Fig. 6, closure of the two limit switches referred to in connection with Fig. 3 results in solenoid 26a opening a valve 26, whereupon air pressure at the left of piston 22 and vacuum at the right overcome spring 24 to move the piston, the piston-rod 23 being connected to restore lever part 1<SP>11</SP> (not shown) to the idling position. For resetting the apparatus, an equalizing conduit 28 rendered effective by a valve 27 is provided, valve 27 being first opened by piston 22 at the end of its travel and then being held open by solenoid 30 having pistonclosed holding switch 27b and spring-closed cut-in switch 29 in its circuit. Resetting occurs after valve 26 has been reclosed. In a muchsimpler variant (Fig. 7, not shown), a solenoid equivalent to solenoid 26a, Fig. 6, changes-over a valve from cylinder-venting to cylinderpressurizing position, whereupon a piston is moved leftwards against the force of a spring, the piston-rod restoring the lever part 1<SP>11</SP> to idling position. In Fig. 8 lever part 1<SP>11</SP> is not restored to idling position when the brakes are applied: instead, the connection to the vehicle motor is rendered ineffective. Thus, if lever part 1<SP>11</SP> is pivoted counter-clockwise from the full-line (idling) position of Fig. 8, Bowden cable 6 pivots lever 40 counter-clockwise to pivot control lever 44 clockwise to a drive position via rod 41, bolt 42 and sleeve 43, which latter by its rightward movement permits limit switch 48 to close. If now the lever 1 is moved in brakeapply direction, limit switch 11 also is permitted to close, whereupon solenoid 45 is energized and withdraws bolt 42. Then tension spring 49 draws sleeve 43 further over rod 41, leftwards, causing pivoting of control lever 44 counter clockwise again to an inoperative position. In a further embodiment (Figs. 9-10b) the connection to the vehicle motor is rotary rather than rectilinear.
