Title: Improvements in warp stop motions for looms for weaving
IPC: D03D51/28
Filed: 1927-09-17
Abstract: 291,269. Hollingworth, E., (Crompton & Knowles Loom Co.). Sept. 17, 1927. Stop-motions, warp; weft forks. -The drop wires D are normally held by the warp threads so that the wider parts 40 of slots in their upper parts allow non-circular bars 42 to oscillate freely in them. When a warp thread breaks, the drop wire, falls so that the bar 42 engages the narrower part 41 of the slot. The drop wire is thereby moved so that its lower end makes contact repeatedly with an insulated bar 60 until an electric circuit is completed through an electromagnet M, Fig. 1, whereby the head 68 of an extension 67 of the weft fork is attracted and prevents the weft from tilting the fork. The weft fork hammer 15 then operates to move the shipper lever 17 to stop the loom, the movement of the lever breaking the circuit through the electromagnet. The bars 42 are oscillated by a cam-operated plate 49 having cam slots through which cranked ends of the bars pass. A hand control 76, 75, 70 is provided for operating the plate 49 to oscillate the drop wire to facilitate the location of the broken warp.

Abstract: 812,188. Filters. STAMICARBON N.V. Aug. 15, 1956, No. 24947/56. Addition to 791,520. Class 46.  In the method and apparatus of the parent Specification the screening deck is curved to define the periphery of a radially symmetrical space with the bars directed so that they may be crossed perpendicularly by liquid flowing along an advancing spiral through the space against the interior of the deck. The screening deck according to Fig. 1, is built up of straight bars 21 each extending obliquely between two co-axial end rings 22, 23, the resulting deck having the form of a hyperboloid. If a band is secured (e.g. by soldering or welding) around the bars at the region of minimum diameter of the hyperboloid and the hyperboloid is then cut in half in a plane perpendicular to the axis two further screening decks according to the invention result, each having opposite ends of different diameters, Fig. 3 (not shown), Fig. 4 shows one such deck (10, 11) at, each end of a hydrocyclone 7 to which material is fed tangentially at 18. Since liquid medium containing particles is supplied by the hydrocyclone to each screening deck as a rotating and advancing liquid body having an axis of rotation coincident with the axis of the screening deck, the whole area of the deck is utilised. Also, the kinetic energy of discharge from the hydrocyclone is utilised as the feeding energy of the screening decks.

Title: Device for detecting and indicating electric potentials
IPC: H03C1/58
Filed: 1947-09-12
Abstract: 654,159. Non-contact-making relays. STANDARD TELEPHONES & CABLES, Ltd. Sept. 12, 1947, No. 25061. Convention date, Dec. 18, 1945. [Class 40 (iv)] In an arrangement, Fig. 4, for detecting an electric potential falling within a specific narrow range, an A.C. source is connected to a discharge tube CC and a relay R through two static electrical switches A, B controlled by the potential vp under test. The switches shown are biassed rectifiers but may be thermistor trigger circuits, hot or cold cathode discharge tubes, hard tube trigger circuits or cathode-ray tubes. One switch A controls the discharge tube when the potential is higher than the specified range and the other B controls the tube when the potential is lower than the range. The output is effective to operate relay R either in the range in which the output characteristics of the two sections overlap or in a gap between the two characteristics. Fig. 5 shows output curves a, b characteristic of the two switches, vb being the voltage required to operate CC and c the combined output of the two sections. The width of the bend xy may be controlled by adjustment of bias potentials x+y, x - y applied to the mid-points of the secondary windings of the input transformer T<SP>1</SP>. By interchanging the bias connections of the two secondary windings, Fig. 13, the output characteristic shown in Fig. 12 is produced. The tube CC<SP>1</SP> is normally operated and is extinguished by a potential within the range. A second discharge tube CC<SP>2</SP> operates with relay R as CC<SP>1</SP> extinguishes. The two switches of Figs. 4, 13 may be separated, Figs. 3, 9 (not shown) the characteristics being as shown in Figs 5, 8. The circuit shown in Fig. 9 is the equivalent of a ring modulator by which it may be replaced. An earthed resistance W is provided in the arrangements of Figs. 4, 13 to prevent false operation when the test potential is disconnected.
