Title: Improvements in or relating to looms for weaving fashioned fabrics and said fabrics
IPC: D03D49/06
Filed: 1924-02-27
Abstract: 233,469. Barnwell, S., and Barnwell, R. H. Feb. 27, 1924. Fashioned fabrics, looms specially designed for; creel-frame arrangements; take-up motions; temples.-In a loom for weaving fashioned fabrics or garments sectional take-up mechanism is employed, each section being independently actuated and controlled by the harness so that a sectional feed of a particular section of the fabric and consequently of particular warps takes place only as and when required. The warps a<x> are taken from cheeses a mounted on a spindle a<1> on both sides of the horizontal bars a<2> of a two part creel A. Each warp end a<x> is passed under and over a fixed tensioning rod a<4>, is weighted at a<8> and then passed over a ground sleeve a<5> from whence it passes through a comb b and around a roller c, the separate warp ends thus being brought into a horizontal plane. The warps are next passed through the dents of a loosely mounted guiding reed d, then through the healds e which are operated by jacquard, dobby or other harness and then through the beat-up reed f<1> and over the lay f. From the lay f the woven fabric passes through a temple g, the temple roller being mounted in spring- controlled slidable slotted brackets g<1> braced by wires g<2>, from which it passes through sectional rolls i, k and over a breast-beam h to ordinary batching mechanism. Each spring-pressed upper roll i is carried upon a spindle i<1> in a pivoted bent frame i<2>, whilst each lower roller k is driven by pinions l, m, and ratchet wheel n, the wheel n being acted upon at the required times to effect the sectional feed. The arrangement for acting on the wheel n comprises a lever o pivoted at o<1>, having a pivoted spring-controlled pawl o<2> engaging the ratchet wheel n and a contacting face o<4>. The other end of the lever o is flexibly connected by a cord &c. o<x> to one of the ordinary healds or jacquard hooks or to a jacquard hook or a heald specially provided for this purpose. Thus when the cords &c. o<x> for any particular section is actuated by the jacquard &c. mechanism the lever o is mounted on its pivot and the pawl o<2> is carried down and slips over the teeth of the wheel n and is set ready for the sectional feed to be effected. At the same time the contacting face o<4> of the lever o is brought into the path of a constantly vibrating cam p so that on the next upward vibration of the cam the lever o is actuated to effect the sectional feed. In a modified arrangement, worm gear may be made use of to work the sectional feed rolls.

Title: Switch actuating mechanism
Inventor: LAWSON ANTHONY NEWTON
IPC: H01H13/24
Filed: 1971-02-25
Abstract: 1,274,605. Retarding action of switches. STANDARD TELEPHONES & CABLES Ltd. 25 Feb., 1971, No. 5406/71. Heading H1N. A push-button-operated mechanism arranged for releasing a normally-operated biased switch unit for a limited duration comprises a plunger slidably mounted in a push-button and spring- urged out of said button with fluid damping retarding the movement of the plunger out of the button more than its movement into the button, the button being mounted in a housing which limits the return travel of the button. As shown, switch 12 is normally held closed by plunger 5 urged against actuator 13 by a relatively strong spring 6. Depression of button 2 moves an 0-ring seal 9 slightly downwards, venting the interior of button 2 via passages 10, allowing plunger 5 to enter button 2 and compressing spring 6; this has no action on switch 12. On release of button 2 the spring 6 urges plunger 5 outwardly of button 2 but the 0-ring is moved to form a seal such that plunger 5 can move only slowly as air leaks into button 2 via a bleed hole 11; thus the plunger and button assembly is freely lifted by the bias of actuator 13 and switch 12 is released. When the flange 4 of button 2 engages the housing 1, the plunger 5 returns actuator 13 to its normally-operated condition and switch 12 is again closed. Thus the maximum possible continuous release duration of switch 12 occurs when button 2 is completely released after being fully depressed, and is predetermined by the spring 6 and bleed hole 11.

Title: Device for simulating the behaviour of a moving body, for example an aircraft
IPC: G09B9/28
Filed: 1955-02-28
Abstract: 788,070. Grounded aircraft trainers. GIRAVIONS DORAND. Feb. 28, 1955 [March 10, 1954 ; July 13, 1954], No. 5905/55. Class 4. A device for simulating the behaviour of an aircraft comprises a fixed support, a member pivoted thereon for limited angular displacement on either side of a position of unstable equilibrium, and a torsion shaft operatively connected with the member and rotatably mounted on the fixed support so that a torsional strain may be set up in the shaft which is adapted, in a predetermined angular reference position of a part thereof spaced from the member, to change the state of unstable equilibrium of the member to a state of neutral equilibrium. Fig. 12 shows duplicated apparatus, comprising a torsion shaft 2 rigidly connected to an upright shaft at the top of which is a weight forming an inverted pendulum 1, and a similar torsion shaft 2<SP>1</SP> and inverted pendulum 1<SP>1</SP>. A dummy control stick 8 is universally pivoted at 61, and is connected to rotate the torsion shafts through linkages 62, 63, so that movement of the stick 8 in one plane actuates shaft 2 only, and movement in a second plane at right angles to the first actuates shaft 2<SP>1</SP> only. The inverted pendulum 1 is connected through linkage 67, 68 to move a source of light 70 approximately vertically. The inverted pendulum 1<SP>1</SP> is connected through a parallelogram linkage 64 to rotate a rod 65 about its centre, whereby as a trainee pilot manipulates the dummy control stick 8, the shadow 72 of rod 65 cast by source 70 is vertically displaced and rotated relative to a reference line 73 in accordance with simulated pitch and roll. The connection between the control stick and either torsion bar may comprise an arrangement of springs and dashpots, Figs. 3, 4, and 7 (not shown) to alter the response of the inverted pendulum to allow for damping terms in the equations of flight. Two of the devices may be connected in series, the inverted pendulum of the first being linked to the control stick of the second, Fig. 2 (not shown). This apparatus may be used to solve the differential equations arising in the study of helicopter flight. In the modification of Fig. 10, a spring 52 extends between one end of a fixed support 53 and a wire 50 connected at 49 to an extension 48 of the inverted pendulum 1. Abutments 59, 60 on a fixed support are contacted by the wire 50 after the pendulum has been deflected through a predetermined angle in either direction, so that the effect of the spring on the pendulum is substantially constant throughout any further deflection. Specification 759,567 is referred to.

Abstract: 1,178,231. Locating faults in cables. POSTMASTER GENERAL. Jan. 16, 1967 [Feb.11, 1966], No.6159/66. Heading G1U. The resistive position of a fault F, Fig. 5, in a cable AB is found by connecting the cable in a bridge of which one arm includes a calibrated variable resistance R5 and the portion AF of the cable, and a second arm comprises the portion FB of the faulty cable and a length CD of "good" cable, the other arm of the bridge comprising resistance arrangements as shown. The bridge is first balanced with switch SB in position 4 and is then unbalanced by switching SB to position 5 whereby the resistance of arm DG is charged. The value of R5 required to rebalance the bridge gives the resistance X of portion AF of cable AB. The location of the fault is then calculated knowing the resistance/unit length of the cable. With switch SA, Fig.1, in position 1 and SB in any position, a circuit is obtained Fig. 2 (not shown) which is used to calibrate the meter M2. With switch SA in position 2 and SB in any position a circuit is obtained Fig. 3 (not shown) which is used to measure the insulation resistance between one conductor connected to the "Line" terminal and another connected to the "Earth" terminal. A Wheatstone bridge Fig. 4 (not shown) used to measure the resistance of a conductor connected between the "Line" and "Return" terminals is obtained by placing switch SA in position 3 and SB in any one of its first three positions. Another bridge Fig. 7 (not shown) is obtained by placing switch SA in position 5 and SB in position 4, this bridge being used to locate broken conductor faults. One arm of the bridge comprises the capacitance to earth of the broken conductor from one of its ends to the fault, a second arm comprises the capacitance to earth of the remainder of the faulty conductor plus a length of "good" conductor and the other arms comprise resistance arrangements, the bridge being supplied by an oscillator OSC.
