Filed: 1953-04-17
Abstract: 724,839. Valves; fluid-pressure servomotor-control systems. GENERAL MOTORS CORPORATION. April 17, 1953 [April 23, 1952], No. 10518/53. Class 135. In a valve for use in a hydraulicallyoperated vehicle steering gear and of the kind which in the neutral position allows a continuous circulation of pressure fluid from an inlet 50, through annular pressure ports 55 and annular spill ports 56 to outlets 51, the edges of the lands 30, 31 of the valve member and of the casing forming the pressure and spill ports are at least in part non-parallel, e.g. the edges of the lands may be inclined, as shown, or have cut-away portions, so that a gradual application of pressure to either of a pair of ports 52 leading to opposite ends of the servomotor is obtained upon displacement of the valve member. The lands 31 are of larger diameter than the central land 30 so that the resultant fluid pressure thereon provides " feel," and the valve member is centred by springs 43. The valve is housed at one end of a cross-rod 13 which has connections 19 with the steerable wheels of the vehicle and a connection through a clamp 25 with the cylinder 23 of the servomotor, the piston being anchored to the frame of the vehicle. The valve is connected to the steering wheel through an arm 11 with a ball- and-socket joint 17. Instead of a double-acting servomotor, two single-acting motors may be used.

Filed: 1963-03-18
Abstract: 1,002,847. Valves. LIPTON L.P. CARBURETTER CO. Ltd. March 18, 1964 [March 18, 1963], No. 10541/63. Heading F2V. Liquid enters a container through a tube 1, fitted with a valve member 9 hinged at 10 and urged towards open position by a spring 13 bearing against a projection 14 from the valve member. A projection 7 from a float arm prevents closure of the valve until a predetermined liquid level in the container is reached when the valve member is released to be closed by inflowing liquid impinging on it, a downturned lip 11 facilitating this action. When the supply if cut off the valve member is reopened by the spring 13. In a modification, a ported piston valve urged upwardly to its open position by a coil spring is employed and the float arm acts through a cam on a ball coacting with an annular groove in a stem depending from the piston valve.

Title: Improvements in and relating to hot strip-finishing trains
IPC: B21B33/00
Filed: 1970-03-05
Abstract: 1,245,915. Rolling; breaking. VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE A.G. 5 March, 1970 [1 April, 1969], No. 10541/70. Headings B3E and B3M. A method of preventing damage to a hot strip-finishing train, having six rolling mill stands 1-6, caused by the leading end of the strip becoming stuck in one of the rolling mill stands 1-3 or in one of their guides 11-13 comprises sensing the time taken for the leading end of the strip to move between two adjacent stands by means of ammeters 61-63 and, in response to a prolonged transit time, a timer 10, 20 or 30 actuates a control unit A. The control unit A actuates flying shears 8, the reversal of roller bed 7 and the drive means to open the nips between those rolling mill stand rolls which engage the stock. Thus the cut off strip section is condensed between the point where sticking has occurred and the stand immediately preceding that point since the roll driving means are not stopped. The remaining strip leaves the rolling mill train 7 and the condensed strip is removed in a known manner. When the end sticking occurs in the nip between the rolls of any of stands 1-3, their motor protecting switches 51-53 actuate the control unit A. If the leading end of the strip sticks in one of the guides 14-16 of the rear rolling mill stands 4-6 a timer 40 or 50 is triggered by an ammeter 64, 65 or 66 to operate the control unit B. When sticking has occurred in one of stands 4-6 the control unit B is operated by the corresponding motor protection switches 54-56. On actuation of unit B it initiates the reversal of roller bed 7 and of scale breaker 9 and by the switch 51 de-energizes the drive means of the first frame 1. The continued operation of the remaining stands which precede the point where sticking has occurred causes the strip to be torn between stands 1 and 2 after which all nips between the working rolls engaging the strip are opened. When the severed strip section has been condensed between the point where sticking has occurred and the stand immediately preceding that point it is removed in a, known manner.

Circular machines.-In control mechanism wherein for some or all of the needles there is a slider such as 14 operated by a jacquard card, provision is made for causing individual needles to be moved to any one of several positions. The jacquard card is preferably a slotted band 30 carried by a grooved roller 31 driven by ratchet gear from a cam moving with the needle-cylinder. Selectors 15 with slotted ends 26 strung on a rod 25 bear on the imperforate parts of the band 30 or are allowed to drop distances depending on whether the steps 27 - - 29 engage the ends of the slots in the band or the selector ends pass right through. The selectors which have dropped are moved horizontally by a driving-bar 23 with steps 34 - - 36 engaging, with variable lostmotion, a depending projection 33. Each selector thus projects the stepped end of a slider 14 into a needle trick. According to the distance moved forward, the corresponding step 16 - - 19 rides on a rotary cam 11. When the step 16 is engaged, the slider clears the corresponding needle jack, as shown, but when other steps are engaged the corresponding needle will be moved into one of several alternative positions to vary the pattern of knit. The sliders are returned by the engagement of their butts 24 with a projection 22 on the bar 23, which is reciprocated by a grooved cam 42. There may be a number of jacquard cards and groups of selectors and sliders operated thereby, working in conjunction. Specification '223,619 is referred to.
