Abstract: 187,241. Pethoud, S. E. Oct. 15, 1921, [Convention date]. Filtering. - A filter element formed of superposed rings of triangular cross-section, Fig. 2, or of a wire, Fig. 1, coiled helically on a bobbin, is supported on the hollow extension 5<3> of a valve plug 5<2> in a casing 4<2> having inlet and outlet connection 4<100>. With the plug in the position shown, petrol or other liquid to be filtered passes downward through the extension 5<3> and filters inward through the coil. Water &c. separated from the petrol collects in a lower chamber 6 which may be provided with inspection holes or formed of transparent material. The valve plug has an aperture 4<10> through which the liquid can pass direct from the inlet to the outlet while the chamber 6 is removed for cleaning. The Specification as open to inspection under Sect. 91 (3) (a) describes also a filtering-partition, Fig. 2 (Cancelled), composed of parallel rods held in position by the turned-up edges of a perforated rectangular metal sheet. Fig. 5 (Cancelled) shows a partition formed of a wire coiled in a shallow perforated cup provided with a central nipple. Wire to form a filtering partition may be coiled upon a conical surface, or it may be arranged on the inner surface instead of on the outer surface of a supporting member. The use of the apparatus for the filtration of fluids in general is suggested. This subject-matter does not appear in the Specification as accepted.

Filed: 1968-06-17
Abstract: 1,210,002. Weft stop motion for shuttleless loom. FATEX S.A. 17 June, 1968 [30 June, 1967], No. 28705/68. Heading D1E. The weft stop motion comprises a pivoted lever 3 having a tensioner 6 at one end and a magnet 15 at the other co-operating with magnetic switches 16-7. Initially when the weft is drawn from the supply the lever is pushed to co-operate with switch 16 by cam 10, or alternatively by an electromagnet. Latterly the lever is free to pivot under the influence of the running yarn. When a weft is selected magnetic switches 39, 40 are closed and opened respectively by magnet 37 on the presenter 36. If the weft is running freely the lever is pivoted to close switch 17 at the same time as switch 20 is closed by rotating magnet 19 to connect a power source 28. Open switches 16, 40 allow the loom to continue operating. If the weft is unselected lever 3 remains vertical (Fig. 10 not shown) and closes switch 16; the loom continues to operate as switches 17, 39 are open. If a weft breaks while being drawn lever 3 remains vertical (Fig. 12 not shown) and a circuit is completed via closed switches 16, 39 to stop the loom. If. an unselected weft is inadvertently drawn switch 17 is closed by the pivoting lever to stop the loom.

Filed: 1968-06-17
Abstract: 1,189,736. Fabric tubes. OSKAR DILO K.G. 17 June, 1968 [4 July, 1967; 9 Oct., 1967; 17 April, 1968], No. 28723/68. Heading F2P. Piping is made from non-woven fabric by winding in overlapping helices on to a drum 2, the layers being secured together by forcing fibres through between the layers by means of needles 4. The dum is provided with circumferential grooves into which the needles reciprocate radially. A fibrous web 6 is fed by conveyer so that it winds in a continuous loop over the drum 2 and a roller 3. The drum tapers from left to right so that the wound tubing 7 may be drawn off axially in flat form by rollers 23 and coiled on to a stone roll 25. In passing from the drum the piping passes through a hole in the frame 1 and, in order to accommodate the rotation of the tubing, the entire take-up mechanism also rotates, driven by motor 29 and gear 26, through which the piping passes at a slot (30, Fig. 5, not shown). In a modification, Fig. 6, the tubing is not flattened but is gripped by pneumatically actuated jaws 41 and drawn off the drum by a reciprocating take-up device riding on rails 31 axially of the drum between limit switches 50, 54. Lengths of piping are cut off by a rotating blade (46, Fig. 8, not shown). The additional roller 3 may be dispensed with. The fabric used may be of synthetic fibres, metal, glass, asbestos or wool. The fabric may include thermoplastic fillers and the tube be subjected to thermal after-treatment. Alternatively, the fabric may contain elastomeric adhesives or other glues or bonding agents. The piping may be used for facing rollers or for filters.

Title: Improvements in or relating to high-voltage isolating switches
IPC: H01H31/28
Filed: 1947-10-28
Abstract: 631,555. Air-break switches. PAROLLE ELECTRICAL PLANT CO., Ltd., and ANDERSON, E. Oct. 28, 1947, No. 28724. [Class 38(v)] A high voltage isolating switch has two relatively movable arms which enable a high contact pressure to be obtained irrespective of the length of the arms. The two arms 2 are pivotally mounted on a rotatable insulator 1 and are connected at their free-ends by a cross-bar 3 which carries a substantially square section contact 4. The fixed contact assembly comprises a 'block 7 with a contact pad 6 and a U-shaped spring 9 carrying a contact pad 8. To close the switch the insulator 1 is turned, which swings the two arms 2 without relative motion between them until the contact 4 is between the contacts 6, 8, as indicated by the chain lines in Fig. 6. In this position the contact 4 abuts a stop 10 and the swinging movement of the. arms 2 is arrested. The further rotation of the insulator 1 causes the arms 2 to move longitudinally in opposite directions so turning the cross bar 3 into the position shown in full lines in Fig. 6. In this position the contact 4 makes contact with the contacts 6, 8 across one of its diagonals..As the contact 6 is rigidly mounted, the contact 4 is offset along the bar 3 so that it makes contact with the contact 6 with a minimum of lateral movement and with the contact 8 with a maximum of lateral movement.

Title: Improvements in or relating to magnetic compasses and correction devices therefor
IPC: G01C17/38
Filed: 1947-10-28
Abstract: 635,108. Magnetic compasses. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MOON, J. H. Oct. 28, 1947, No. 28771. [Class 97 (ii)] An electromagnetic compensator for magnetic compasses to correct the deviation caused by intermittently used interfering electrical equipment comprises a single solenoid having its axis horizontal for generating a D.C. electromagnetic field whose strength and direction relative to the fore-and-aft line of the craft in which the compass is mounted may be adjusted and whose energizing circuit is interlocked with electrical apparatus whose intermittent effects are to be compensated. As shown, the solenoid 4 is mounted horizontally and diametrically in a flanged ring 3 which is rotatably mounted in a non-ferro-magnetic housing 1 adapted to be secured beneath the standard magnetic corrector 2 provided below the compass. During insertion the upward movement of the ring 3 is limited by projections 5 and it is incapable of being rotated until its flange clears three projecting pins 6, 6, 6a for which slots 7 are provided in the ring. A keeper ring 9 for the ring 3 is capable of axial but not of rotational increment with respect to the housing 1. A lock-nut 13 and washer 13a are provided which lock the parts 3 and 9 in adjusted position. The rotation of the .ring 3 is limited to one turn by a ball 8 engaging with the third pin 6a and the amount of rotation is indicated through a window 11, 12 by a scale engraved on the periphery of the ring 3, the two halves of the scale being in different colours. A side housing 16 accommodates a resistance 17 by means of which the current through the solenoid 4 may be varied and a plug-connector for a supply socket 20. The energizing circuit for the solenoid 4 is wired to the supply circuit of the interfering equipment so that the corrector circuit is automatically switched on and off with the interference. In use the aircraft is swung without the electromagnetic corrector in operation both without and with the interfering apparatus in operation. The aircraft is then swung to a heading obtained from the latter operation whereat zero deviation with interference was recorded and the solenoid switched on. The solenoid is then rotated until the compass reading is again correct. The craft is then turned through 90 degrees and the strength of the solenoid current adjusted until the compass shows the same reading whether the interfering apparatus is working or not. The compass is then corrected for all headings. The axis of rotation of the solenoid may be offset with respect to the compass axis in order to compensate for non-linear deviations such as field alignment errors.
