Title: Improvements in and relating to spinning rings for spinning or twisting machines and in and relating to the lubrication thereof
Inventor: ATWOOD HYATT BICKNELL
IPC: D01H7/62
Filed: 1958-10-20
Abstract: 900,405. Lubricating spinning rings. HERR MANUFACTURING CO. Inc. Oct. 20, 1958, No. 33480/58. Class 120 (2). A method of lubricating the traveller bearing surfaces 14, 15 of spinning rings of the type having a capillary passage 11 or 12, terminating at a bearing surface of the ring, includes the step of supplying lubricant under pressure to said passage so that the flow of lubricant through the passage is accelerated above the rate of flow if no pressure were present and so that the supply of lubricant through said passage would be maintained by capillary action even if the pressure were arrested. As shown, the ring consists of a holder 8 carrying a body portion 9 and an inner ring 10 which are separated by the capillary passages 11 and 12 and form an annular reservoir 16 which is automatically refilled at intervals from the container 33 by the pump 32 ; this operation also increases the flow of lubricant to the bearing surfaces and clears the passages 11 and 12. The ring 10 may be spot welded at a series of points to the body portion 9 (see Figs. 4 and 6, not shown) so as to form capillary passages of varying width. In other forms the contacting surfaces of the ring 10 and portion 9 may be smooth, slightly corrugated or knurled or the inner ring may be secured to the portion 9 by making it a tight fit or by peening. If the lubricant is supplied in atomized form in a current of air some of it condenses in the reservoir 16 so that lubrication by capillary action can still take place. Specification 861,143 is referred to.

Title: Improvements relating to fluidic devices
Inventor: SYKES NEIL WINN
IPC: D05B65/00
Filed: 1968-07-12
Abstract: 1281873 Starting and stopping PLESSEY CO Ltd 18 Sept 1969 [12 July 1968] 33489/68 Heading D1G In a sewing machine the presser foot carries two fluidic back-pressure sensor devices J1, J2 which respectively sense the presence or absence of material to be stitched and control the starting and stopping of the machine. Device J2 also actuates a cutter 7, 8, 9 which severs the threads after sewing and any tape sewn to the material. A further device J3 detects the presence of the lowered cutter blade and causes the blade to rise after cutting. Operation (Fig. 3) When the front edge of the material is sensed by device J2 a back pressure signal is applied to input C1 of a fluidic switching device A. The consequent output 02 of the latter operates an amplifying device to release and engage respectively the brake and motor clutch (not shown) of the continuously running motor. The arrival of the front edge at device J2 sends a signal to switching device B which provides a hold on signal C2 to device A and to bi-stable device D to switch the latter to its output 02 which feeds an AND device C. When the trailing edge passes from under device J1 device A remains held on until that edge passes from under device J2 to remove its signal to device B which now supplies a signal to AND device C, the latter actuating an amplifying valve (not shown) which causes the cutter blade 6 to descend. When that blade reaches its fully down position the device J3 operates bi-stable device D to remove its input 02 from the AND device C and the cutter rises.

Abstract: 429,443. Ironing-presses. MARRIOTT, H. L., 103, Kingsway, London.-(American Laundry Machinery Co. ; Norwood, Ohio, U.S.A.) Nov. 30, 1933, No. 33640. [Class 138 (ii)] A two-handed control for the fluid-pressure supply to the cylinder 16 in which the piston 15 operating the press works, requiring sustained manual operation to maintain the fluid supply until the press is closed whereupon the controls are automatically maintained mechanically, comprises two inlet valves 26, Fig. 7, in the supply pipe 23 and connected in series by a pipe 22. Exhaust valves 27 operating in the reverse order to the inlet valves are provided in the valve chambers and each pair of valves is linked to a lever 32. The levers are normally maintained in the position shown in Fig. 7, and in the dotted line position of Fig. 2 by the spring toggle arrangement 33, 33<1>, the link 33<1> being pivoted at 33<11> to the stationary frame. On manually moving the levers to the horizontal position, the valves 28 are opened and valves 27 closed ; the toggles 28, 33<1> not yet having reached straight-line position necessitate continued manual operation of the levers 32. Further depression of the levers to a position, not shown, wherein the straight-line position of the toggles 28, 33<1> has been passed-so that the manual control may be released and the levers maintained depressed by the springs 33- is prevented by the engagement beneath the levers 32 of arms 34 mounted on a rock-shaft and connected by rods 35 with the pressclosing mechanism through a lost-motion connection. When the press reaches a predetermined closed position the arms 34 are rocked clockwise, enabling the operator to depress the levers 32 further, lost motion connections 40 being provided between the valves 27 and the levers since the valves 27 have already been fully closed. The press is opened by the operator raising one of the levers ; the other is automatically raised by the reverse movement of the arms 34. In a modification, the arms 34 are rocked by a piston mechanism, the access of fluid pressure to which is controlled by the movements of the main press-operating piston.

Title: Improvements in or relating to a process and installation for separating and storing tar
IPC: C10C1/18
Filed: 1954-11-24
Abstract: 803,700. Separation and storage of tar. STILL, K. F., [trading as STILL, C., [Firm of]]. Nov. 24, 1954 [Nov. 30, 1953], No. 34125/54. Class 55 (2). A process for separating and storing tar includes the step of circulating tar contained in a separating vessel by continuously withdrawing tar therefrom and returning thereto only a part of the withdrawn tar and feeding the remainder thereof to a storage vessel. A tank 7 receives condensates from indirect crude gas coolers via conduit 8 and this is pumped at 9 via conduit 10 to the oven main 1. From the oven main 1, the liquor passes through conduit 11 to a thick tar collector 2 and thence to the tar separating vessel 3 through conduit 12 terminating in a distributer nozzle 13. The tar settles in a conical vessel 14 whence it can be removed by conduit 16 by means of a pump 15. An overflow pot 4 can be connected into conduit 16 by means of valve 17 through conduits 18, 19 at each side of the valve, the pot 4 being vented to atmosphere at 50. When valve 17 is closed, tar flows into pot 4 until the level reaches the outlet to conduit 19, when pump 15 may be used to lower the level. Periodically valve 17 may be opened to allow the vessel 3 and conduit 16 to be emptied of tar to prevent gradual clogging of the pipe. Conduit 16 is joined to conduit 20 and via a valve 21 to conduit 22 which terminates in a discharge nozzle 23 inside a storage vessel 5 with a conical container 24 having discharge pipe 25 controlled by a valve 26. The setting of valve 21 is arranged to give the desired ratio of tar being returned to the vessel 3 to that passing to the storage vessel 5. Conduit 20 is connected to a straining vessel 27 with a filter 28 for the removal of large impurities removable through outlet 29. The outlet of vessel 27 is either joined by conduit 30 directly into the conduit 12, or passes into the container 14 through a discharge nozzle or, as shown, passes into the container 14 through a distributer ring 32 with discharge orifices 33. The tar in vessels 3 and 5 is maintained in a fluid state by heating jackets, the conical vessels 14, 24 having annular chambers 41, 42, the chamber 41 being supplied with hot condensate free from tar from the upper part of vessel 3 by way of overflow pipes 43, 44, the liquid then being pumped via pipe 45 and pump 46 to chamber 42 and then via pipe 47 to a sprinkler 48 in the oven main 1.
