Title: Improvements in or appertaining to weft replenishing mechanism for looms
IPC: D03D45/20
Filed: 1919-06-27
Abstract: 141,969. Hollingworth, E., (Crompton & Knowles Loom Works). June 27, 1919. Shuttles, changing weft carriers in, automatically; weft-feeler arrangements.-The transferrer 21, Figs. 1 and 2, is moved downwards at each alternate beat-up by means of a link 23, and carries a feeler-lever 27, which, when the weft is substantially exhausted, causes the rotary magazine to be operated to position a weft carrier beneath the transferrer, so that on the next operation of the transferrer, this weft carrier is transferred into the shuttle, the weft-carrier space beneath the transferrer being normally vacant. The lever 27, carrying the weft-detector 25, is pivoted at 28 to a lateral extension of the transferrer and is acted upon by a spring 27<a>, so that normally an upward extension 37 of the detector engages a stop plate 38 on the transferrer. When the transferrer moves downwards, an extension 30 of the lever 27 engages a spring-controlled arm or trip 31 pivoted to a fixed arm. If sufficient weft is present on the weft carrier, the arm 31 is depressed as shown in Fig. 5, but otherwise the detector 25 moves sideways as shown in Fig. 6, and operates a pin or stud 39, which is loosely mounted on the transferrer and upon the upward movement thereof engages a cam 44 on an arm 43 of the magazine feed-lever 42. By means of a spring-controlled pawl 41, the lever 42 turns the magazine the space of one tooth, the foremost weft carrier overcoming the resistance of a spring-controlled stop 17 and moving up to a stop 16 into position beneath the transferrer, the weft carrier tip being supported by the arm 31, which also supports it during the transfer into the shuttle. When the feed-lever 42 returns under the action of a spring 47, a cam 50 on the arm 43 returns the stud 39 to normal position.

Abstract: 991,243. Ball and socket joints. THOMPSON RAMO WOOLDRIDGE Inc. April 20, 1964 [April 30, 1963], No. 16285/64. Heading E2F. [Also in Division F2] A boot seal for a ball and socket joint comprises a resilient sleeve 21 which is formed at one end with an end wall 36 that sealingly engages a member 38 secured to the ball pin 49 and, at the opposite end, with an internal sealing lip 26 which normally engages the socket 28 but is unseated, as shown in Fig. 6, by expansion of the sleeve to relieve any excess pressure occurring in the sleeve, for example during lubrication of the joint. The sleeve is reinforced adjacent the wall 36 by an embedded ring and has at the other end an external bead 24 surrounded by a rigid ring 22 having a skirt 39 which lines the bore 23 of the sleeve terminating at the lip 26, embraces the face 27a of the socket 28 and has axial grooves 44 which interconnect the low pressure side of the lip 26 with the atmosphere. When the joint is charged with lubricant through a nipple 56 any excess pressure in the sleeve interior 61 causes the lip 26 to unseat and excess lubricant then escapes through grooves 44 until the pressure returns to normal and the lip again engages the socket. The sleeve is preferably of synthetic material, such as neoprene, and the ring 22 is preferably of corrosion resistant metal such as zinc or cadmium plated steel. In a modification, the ring 22 is replaced by a segmental L-section ring 62, Fig. 7, having a gap 66 between its ends 63, 64 through which excess pressure can escape as shown in Fig. 10. In a further modification, the ring 72, Fig. 11, has transverse slots 73 in its outer periphery which act as relief passages as shown in Fig. 14. The ball member 48 is supported in the socket 28 by a split bearing ring 51 of nylon urged upwardly by a spring 52.

Title: Improved drawing apparatus
Inventor: BEAUMONT ALBERT GORDON
IPC: D02J1/22
Filed: 1967-04-12
Abstract: 1,215,143. Apparatus for drawing synthetic filaments. COURTAULDS Ltd. 11 April, 1968 [12 April, 1967], No. 16847/67. Heading B5B. An apparatus for drawing bundles of synthetic filaments comprises a feed roll 1 driven by a roller 2, and a guide 4, grooved at the pitch of the three wraps of the running bundle of filaments 3 round the roll 1. The guide 4 is driven to reciprocate axially, parallel to the roll 1 whereby the wraps move to and fro along the surface of the roll 1 and the position at which the bundle 3 leaves the roll 1, in relation to the roll 1, is simultaneously varied. The bundle 3 is taken up on a draw roll 5 and a co-operating bundle-advancing roller guide 6 in two wraps, and leaves the roll 5 to be collected on a bobbin (not shown). Between the rolls 1 and 5 the bundle 3 bears on a pin 7 fixed horizontally on a structural member 8 with its longitudinal axis disposed in a direction at 45 degrees to the axes of both the feed and draw rolls 1 and 5 when the apparatus is viewed in plan. The pin thus functions as a deflector. The path of the bundle 3 from the feed roll 1 to the draw roll 5 is shown in the drawing as a solid line 3 and as two broken lines 3A and 3B which are the paths followed at different stages of the reciprocation of the grooved guide 4. The pin 7 induces the bundle 3 to reciprocate longitudinally of the draw roll 5, thus avoiding the necessity of providing mechanism for the longitudinal reciprocation of the guide 6. The pin 7 may also function as a snubbing pin if the bundle 3 is passed in one turn about the pin 7 instead of bearing on only one side of the pin. The object of causing the paths of the wraps of the bundle of filaments round the feed and draw rolls and the advancing roller guide 6 to reciprocate along the rolls is to prevent localized wear of the rolls and the roller guide due to the abrasive action of the filaments.

Abstract: 789,022. Nuclear reactors. GENERAL ELECTRIC CO., Ltd. June 8, 1956 [June 10, 1955], No. 16850/55. Class 39(4). From a nuclear reactor cooled by a fluid under pressure, fuel elements are removed or inserted by using an auxiliary pressure vessel 16 temporarily sealed to the reactor so that the temperature and pressure of the coolant is maintained. The fuel elements are housed in vertical passages 2 in a graphite core 1 and a tube 13 is aligned with each passage. Preparatory to charging or discharging fuel elements the vessel 16 is attached to the top of a tube 13 by a breech-block device 18, and is filled with coolant gas at the same pressure as exists in the reactor. An oval door 14, Fig. 2, closing the top of each tube 13, is inclined and removed to within the vessel 16 by remote control, taking with it a concrete plug 19 on a chain 20. Still by remote control, pressure is exerted on the top fuel element, causing a pin below the bottom element to shear and allow all elements in that passage 2 to fall and slide on to a plug 28. This plug 28 may be withdrawn into an auxiliary pressure vessel 26 from which it can be extracted. In an alternative arrangement, Figs. 7 and 8 (not shown), a single auxiliary pressure vessel is employed below the reactor and is positioned below one of the passages 2 to charge or discharge fuel elements. The core 1 is supported on a grid 3 and brackets 4 within a pressure vessel 5, supported in turn by brackets 6 on legs 7. Coolant gas is admitted at 8 and extracted at 9. Rods 11 control the reactor. The core 1 has an outer reflector portion 1B comprising graphite blocks without fuel elemerits. A further auxiliary vessel may be used for charging the control rods or for other services.
