Title: Method of catching a thread
IPC: B65H67/04
Filed: 1976-04-13
Abstract: 1534951 Winding up continuously supplied thread; thread catching means MASCHINENFABRIK RIETER AG 13 April 1976 [16 April 1975] 15017/76 Heading D1J The invention relates to a method of catching a thread in a yarn winding apparatus and in particular in apparatus of the kind in which a continuously supplied thread has to be wound up on successive bobbin tubes without interruption of the thread flow. The method comprises moving a suction tube 2 and a thread gripper 3, 4 jointly from position A, Fig. 2, into position B so as to extend into the traversing triangle of the thread 12 being wound onto a fully wound bobbin 16; catching the thread in recesses 5, 6 in the thread grippers 3, 4; severing the thread by moving gripper 3 relatively to gripper 4, and sucking off the severed end of the incoming thread into the suction tube 2. The suction tube 2 and thread grippers 3, 4 are then moved jointly back to the start position A. The full bobbin package 16 is then exchanged for an empty bobbin tube 17 by the bobbin change device and the empty bobbin is brought up to speed. The suction tube 2 and grippers 3, 4 are then swung jointly to a setting C in which they are aligned with the bore of the empty bobbin 17 and they are then jointly advanced to a setting in which they extend into the bobbin tube 17 as illustrated in Fig. 3. Since the empty bobbin tube 17 is rotating, the thread extending from the supply into the suction tube 2 becomes snagged in a notch 21 in the end of the tube 17. This causes the thread from the supply to be wound onto the empty bobbin tube and the thread in the suction tube 2 to be wound around the grippers 3, 4. The grippers 3, 4 are, however, continually moving relatively to each other so as to produce a continual cutting action and for this reason the turns that tend to be wound up on the grippers 3, 4 are cut away. The suction tube 2 and grippers 3, 4 can then be retracted from the tube 17 and the normal build up of the package onto the bobbin 17 commenced.

Title: Improvements in or relating to low pressure food steamers
IPC: A47J27/16
Filed: 1934-05-18
Abstract: 437,048. Valves. CLARKE, W. L., 100, Garratt Lane, Wandsworth, and BENHAM & SONS, Ltd., 66, Wigmore Street, both in London. May 18, 1934, No. 15063. [Class 135] [See also Group VI] A food steamer of the kind comprising a steamer body, a boiler in communication therewith and temperature or pressure responsive means for controlling the supply of heat, is provided, in addition, with a safety valve for the steamer body, a self-opening air valve for venting air displaced by the steam and for admitting air to prevent the formation of a vacuum when the steamer is cooling after use, and a constant level automatic water feed to the boiler which prevents the flow of water from the boiler to the water supply under the pressure of the steam. As described, the bottom of the steamer body constitutes the boiler, the heating being effected by gas burners controlled by a thermostat. Fig. 2 shows the water-supply control valve, the float 6 being in the water at the base of the steamer body 1 which is enclosed in an outer casing 21. The arm 7 is pivoted at 8 and is formed in two parts 24, 25 locked together by a finger-operated device 27. The valve 5 is provided with a spring-pressed buffer block 14 and with a finger piece 23 which facilitates removal of the valve when the cap 22 is removed. The water is admitted to the boiler through the opening 18 and the conduit 20. The safety valve, Fig. 3, is in communication with the top of the steamer body, and comprises a base 35, screwed to the upper end of the vent pipe, a screwed cover 39 and a gravity loaded valve block 38 slidable within the cover and arranged to seat normally on the seating 37. The air relief comprises a light valve 41 retained in position by a screwed sleeve 43. When the air is expelled from the steamer, it escapes through the arches 44, past the tapered valve seat 46 and through openings 47 in an upwardly projecting guide extension of the valve 41, the valve remaining on the sleeve 43. When the air is expelled and the steam pressure rises, the valve 41 is raised against the seat 46 and thereafter the valves 38, 41 move as one. The block 38 may be turned on its seat, to clear any deposit, by the handle 54 on a spindle 51 carrying a crosshead 53 slidably engaging pins 52 on the block. A modified water supply control is shown in Fig. 4, the apparatus shown being immersed in a constant level water tank, the pipe 59 being the supply pipe to the boiler. The valve member 60 is loaded with oil 64 so that it will just sink. The pressure of the steam in the boiler tends to return water to the water tank, but this is prevented by the valve 60 rising and seating its washer 62 against the seat 63 on the cover of the casing 55. When the steam pressure drops, e.g. when the cooker door is opened, the valve 60 drops on to the surface 61 and water flows through the openings 57, around and underneath the valve and through the pipe 59 to the boiler. The oil is admitted to the valve 60 through the hollow stem 65 which is guided in the boss 66 of the cover.

Abstract: 457,461. Direct explosion apparatus for raising liquids. CHRISTIE, S. P., 12A, Ennismore Gardens, South Kensington, London. May 27, 1935, No. 15447. [Class 102 (ii)] In a two-stroke internal-combustion liquid piston pump the fuel and/or air inlet valve 33 is timed by a piston 1 loaded by a spring 7 and exposed to the suction existing in the exhaust pipe 4, when the exhaust valve 9 is opened. The opening of the exhaust valve 9 compresses spring 16 and tends to tilt the mercury switch 12 which is held by a detent 14. As the pressure builds up in the combustion space the spring 7 raises the piston 1 and the collar 15 engages a stop on the rod 18 and releases the detent 14, allowing the switch 12 to energize the solenoid 11 and permit valve 33 to open. If an explosion occurs, the spring loaded piston 23 is raised causing the stop 100 to engage the lever 22 and reset the detent. A non-return valve may be fitted between the cylinder 2 and the exhaust pipe 4 and a throttled pipe fitted to connect the two so that there is a delayed action when the spring 7 comes into action. Fig. 3 shows a modification wherein the disc 15 engages a stop 52 and tilts the switch 12, the stop 52 being arranged on a lever 51 connected through a spring to the exhaust valve 9.
