Abstract: 879,583. Valves. SEPARATOR A.B. Jan. 13, 1959 [Feb. 13, 1958], No. 1210/59. Class 135. Apparatus for keeping constant and for regulating independently the flow of fluid through a pipe line from an inlet 18 to an outlet 19, comprises a flow-responsive member 2 in the pipe line, an inlet control valve actuated by the flow-responsive member, and a sleeve 8 open at its ends and surrounding the flow-responsive member, the sleeve being manually displaceable relative to closure means between three positions in one of which positions a by-pass between the sleeve and the pipeline is open to allow some fluid to by-pass the flow-responsive member, in a second of which the by-pass is closed by the closure means and fluid can only flow through the sleeve and in another of which the by-pass and the sleeve are both closed by the closure means so that no fluid can flow. The inlet valve comprises an inlet member 4 provided with two plane parallel seating surfaces through which holes 17 open into the pipe line, these surfaces being embraced by the forked end of an arm 6 pivoted to the inlet member at 5 and constituting a valve closure member, the arm being articulated to a stem 7 of the body 2.

Abstract: 1416115 Mechanical or fluid actuation of spot-type disc brakes; wear-adjusting BENDIX CORP 10 Jan 1974 [31 Jan 1973] 01259/74 Heading F2E In a spot-type disc brake comprising a disc 12 and a pair of friction elements 18, 20, associated with a caliper 24 straddling the disc and slidably mounted on a torque member 22 mounted adjacent face 14 of the disc, mechanical actuating means including a first member 52 and a second member 50 mounted in a bore 32 in the caliper 24, first means (e.g. 85, 86) for holding the first member 52 against rotation with respect to the caliper, second means (e.g. 84, 86) for holding the second member 50 against translation with respect to the caliper, and third means (e.g. lever 96) for rotating the second member 50, the first member 52 being operably connected to one of the friction elements (e.g. 18), camming means 100, 102, 104 being disposed between the members 52, 50, so that on rotation of the second member 50 the first member 52 is driven away from the second member and thereby urges friction element 18 towards the corresponding disc face 14 and, by reactionthrough the caliper, friction element 20 towards disc face 16, the members 52, 50, are coaxial to present an inner member 52 and an outer member 50, the first and second means including stop means 86 carried by the caliper 24 and extending through the members 50, 52, to prevent rotation of the first member 52 while preventing axial movement of the second member 50 and limiting the arc of rotation of the latter. As shown, the stop means is a pin 86 and sleeve 84 extending through circumferentially extending slots 80, 82 (see also Fig. 2) in the second member 50 and a diametral longitudinal slot 78 in the first member 52. First resilient means (release spring 88) extends between the first member 52 and sleeve 84. Bore 32 is stepped, with an hydraulicallyactuable piston 40 slidably mounted in the larger-diameter section 34, the piston serving operably to connect the first member 52 to friction element 18; the first member 52 comprises two elements 64, 66, so as to be extendible in response to hydraulic movement of the piston 40 towards the disc in excess of a predetermined amount so that on release of hydraulic actuation piston retraction is limited. Second resilient means (spring washer 70) connects piston 40 and element 66 to transmit excess piston movement, automatic extension of member 52 occurring by consequent unscrewing of element 66 from element 64 at threads 68; the spring rate of washer 70 is less than that of spring 88. (Spring washer 70 engages element 66 through a bearing 72 carried by element 66). The camming means is preferably at least one sphere 104 located in opposing recesses 100, 102 so that on rotation of the second member 50 by a parking actuator (not shown) through lever 96, members 52, 50 are longitudinally separated. Rotation of member 50 is assisted by bearing parts 60, 62.

Apparatus for the spinning of slubbed continuous filaments comprises a take-up roller around which filaments, freshly formed and travelling from a jet, may be wound, driving means for rotating the take-up roller and auxiliary driving means capable of intermittently driving the take-up roller so as to intermittently increase its speed of rotation above that produced by the driving means whereby the filaments are drawn from the jet by the take-up roller at an intermittently increased rate and negative slubs are thus formed in the filaments. The auxiliary driving means may be continuously applied to the take-up roller and the driving means can be intermittently disengaged from the take-up roller, the driving means, when in engagement with the take-up roller, over-riding the auxiliary driving means. The driving means may be a rotatable roller which drives the take-up roller by frictional contact therewith, the two rollers being adjacent with parallel axes and the take-up roller being provided with a circumferential raised portion to contact frictionally the driving roller. The auxiliary driving means may be the filaments drawn from the take-up roller by the filament collecting device, which may be a cap-spinner. The apparatus may also include an intermittently operated brake to reduce the speed of the take-up roller intermittently to cause slubs to form.

Abstract: 871,821. Coin-freed parking meters. WHITE, P. L. Jan. 21, 1958 [Jan. 21, 1957], No. 2146/57. Class 27 A parking meter of the kind having a spring or electric-motor driven timing mechanism in which the driving means of the timing mechanism is started by a coin-acceptance mechanism, comprises switching means operable by the timing mechanism or by tripping means at the expiration of a parking period to give a predetermined lamp indication. Within a weatherproof casing 1 is housed any suitable form of coin-acceptance mechanism having at least one coin-receiving slot 2 and a return-coin receptacle 3. This mechanism is arranged to effect the closure of a starting switch 4, Fig. 2, upon the acceptance of a coin or coins appropriate to the required parking period. In the embodiment described, the timing element is an electric motor 6 connected across mains 5 having its rotor coupled through gearing to a shaft 7 which rotates a pointer 8 movable over a time-scale 9. A plate 10 mounted below the timing mechanism, pivoted at 11 about an axis parallel to the pointer shaft 7, carries switching means, e.g. a pair of mercury switches having change-over contacts 13 and normally open contacts 14. The insertion of a coin or coins in the slot 2 closes the switch 4 and also tilts the plate 10 in a direction to cause the closing of the contacts 13 and 14, thus energising the motor to rotate the pointer 8 and an arm 17. An "engaged" lamp 17a, preferably green, is put into circuit by the closing of the contact 13. Just prior to the expiration of the parking period, the actuating arm 17 engages a pin 15 which tilts the plate 10 to effect reverse action of the mercury switches mounted on the plate so that the contacts 14 are opened to interrupt the supply to the timing element, extinguish the "engaged" or green lamp, and put into circuit a "time-expired" red lamp 18. A knob 19 is provided for re-setting the meter; it may be rotated to turn the pointer and actuating arm 17 back to their normal positions and it may also be used to open the switch 4 to extinguish the lamp 18. The plate 10 is arranged to remain in its deflected position until a pin 16 is engaged by the arm 17 during the latter part of the resetting movement to restore the plate 10 to its normal position and the contacts 13 to the position shown in Fig. 2. The indicator lamps may be protected by a transparent cover 20.
