Title: Improvements in automatic axially-acting two-way slack adjusters for vehicle brake riggings
IPC: B61H15/00
Filed: 1965-09-13
Abstract: An automatic two-way slack adjuster of a particular kind and in which, when no braking force is being transmitted, the feeding nut is in clutchable engagement with the housing, is characterized by the nut 24 and the housing at 17 being provided with teeth for the clutchable engagement. In the arrangement shown in Fig. 2, the brake is applied by leftward movement of the member 18, a usual stationary stop 14, not shown, being provided to abut with the housing 15. The adjuster reduces excessive slack but pays out only during its second operation to take up insufficient slack to prevent such paying out due to dirt, rust or ice on the brake. Normal operation.-Brake operating force is transmitted to member 19 through spring 42 until this yields, clutch d-d then engaging to transmit the force through members 20, c-c, 33, 35, 29, 30, d-d to locking nut 23. As parts 18 and 19 advance further, the blocks abut the wheel and housing 15 is maintained stationary by abutment with stop 14, spring 42 is compressed to disengage clutch e-e and after flange 56 abuts ring 59 nut 24 spins as 19 is drawn therethrough. Excessive slack.-The housing abuts stop 14 before the operating force has risen sufficiently to compress spring 35 and clutch a-a remains engaged. As 18, 19 move within the stationary housing, clutch e-e is disengaged and when members 59, 56 abut the feeding nut 24 rotates until the axial distance between flange 54 and nut 23 increases to correspond to the excess slack. During release clutch a-a is engaged and housing 15 and nut 24 are prevented from rotating and the distance between the housing face and the stop 14 increases until the force has dropped sufficiently for clutch d-d to disengage, when lock-nut 23 is freed to rotate until flange 54 abuts nut 23, the members 18, 19 having then been telescoped to take up the excessive slack. Insufficient slack.-During the first operation, spring 42 first yields to disengage clutch b-b and engage clutch d-d. When spring 35 yields a distance " S," corresponding to the insufficient slack between the housing and stop 14, clutch a-a disengages and spring 42 expands while the assembly 15, 24, 42 rotates until the housing abuts stop 14 and thus registers the distance " S." Subsequently the action is the same as with normal slack operation, nut 24 idling as before. During a second application with insufficient slack spring 42 yields as before to open b-b. Owing to the force of spring 53, which has been compressed during the prior registration of distance " S," nut 23 spins to allow flanges 55, 56 to abut, rod 18 moving forward through distance " S " while part 19 remains stationary. Stop 14 is engaged and part 18 moves forwardly through distance S, compressing spring 42 before the braking force reaches that of the strong spring 35. A modified arrangement is illustrated in Fig. 4 (not shown). Manual adjustment is effected by rotating the housing 15.

Patent ES-355320-A1 (ES)
Title: Feedback control monitor for stored program data processing system
IPC: G06F9/48
Filed: 1968-06-12
Abstract: Stored program data processing machine has a plurality of logic means each adapted to process a respective class of work, a plurality of storage locations each of which is adapted to store requests for performing a respective one of the classes of work, means for interrupting the processing of any of the classes of work to process a class of work of higher priority, means for determining the period from the interruption to the recommencement of processing of a first class of work and means responsive to the determining means to regulate the number of items to be taken from a storage location to perform work of another class. A processing machine of the kind described in Specifications 1,081,811 to 1,081,817 performs 8 base level jobs in the order EABACABADAB ACABAE and has interrupts of various priorities, an interrupt J being performed every 5 m.secs. Every twenty-fourth J interrupt, i.e. every 120 m.sec. path 245 (Fig. 2) is activated. This commences a programme designed to determine the time between E level jobs and to reduce this time if it has taken longer than a predetermined time by decreasing the amount of work done in the D level. Each level has a hopper storing work requests and more or less requests may be extracted from the hopper depending on the time lapse occurring between the E levels. If during a J level interrupt the E revisit time average over the last three visits is more than 1 second the calling rate is reduced 6% and if more than 1À8 seconds the system is placed in an overload state wherein scanning for new requests is omitted. If more than 8 seconds is taken emergency action is taken. Fig. 2 shows the procedure occurring on every twenty-fourth J interrupt, i.e. every 120 milliseconds. Counters JTIM and INCTIM are incremented to show elapsed time and if AC # V is not set the value in cell EIST is subtracted from JTIM (EIST holds the value which was present in JTIM when an E level was performed three times ago). The result is compared with 5À4 sees. If it is less it is compared with 3À0 sees. and if less processing work proceeds. If EIST is more than 5À4 sees. AC#V is set. If AC#V is set the difference between JTIM and E3RD is calculated (E3RD being the level of JTIM at the last prior E-level visit). The elapsed time is compared with 8 seconds and if it is greater an emergency phase is commenced. The Specification includes a flow path (Fig. 3, not shown) for updating the values of EIST and E3RD and a flow path for altering the access rate to the D-level buffer (Figs. 4A, 4B, not shown).

Attached to member 4 are central and corner landing pads 12, 14. The inner and outer edges 23, 26 of walls 19, 21 are fluid-tightly sealed by perimeter binding tapes 23, 28, and wall 19 is provided with an inlet aperture 42 and surge outlet apertures 44. Initially, with torus 17 deflated, pressurized fluid from inlet 40 enters the body via aperture 42, whereupon the body assumes a rounded shape and the fluid from inlet 40 maintains pressure: in the plenum chamber and the torus chamber 31. Pressure build-up breaks the bearing seal between sheet 21 and the ground surface 16, and a perimetrical throttling gap 48 is established. Unbalanced loads or uneven surfaces effect rapid pressure equalization via surge outlets 44, thus ensuring stability of operation. In an alternative embodiment, Fig. 6 (not shown), the upper wall portion is formed by a pair of flexible sheets having overlapping edges. clamped to the backing member. The skirt is made of a laminated multi-ply non-porous material having the warp of adjacent plies positioned at an angle from one another, and it is stated that this increases the dimensional stability and makes more uniform any distortion in the torus.
