Title: Apparatus for forming textile or like fibres into a web
Inventor: CALLAGHAN ALBERT EDWARD
IPC: D04H1/736
Filed: 1958-03-03
Abstract: 919,531. Forming fibre webs. CALLAGHAN & SON Ltd., A. E. June 2, 1959 [March 3, 1958], No. 6753/58. Class 120 (1). Fibres to be formed into a web are blown on to a pair of gas-pervious rotatable rolls, the upper one of which is movable so as to float on the fibrous web as it passes between the rolls. In order partially to counterbalance the weight of the upper roll 7 and thus decrease the pressure of the roll on the web, the rolls are mounted on hollow stub shafts 33, 34 which are connected by calliper arms 35 in turn connected through a spring-loaded device 36 provided with a thumb-nut adjustment 37. Baffle plates 39 mounted within the rolls 6, 7 shroud rear portions of the roll peripheries, the plates being mounted for adjustment by levers 42. Fibrous materials that may be processed include asbestos, leather, paper, wool, flax, cotton, jute, coir, cellulose acetate, rayon and synthetic fibres. These materials may be fed directly to a blower to be carried in a blast of air to the rolls or may be injected into the air blast from a hopper-fed opener or teasing and blending machine. Specification 835,215 is referred to. Reference has been directed by the Comptroller to Specification 895,139.

Title: Hydraulic oscillation-dampers
IPC: F16F9/32
Filed: 1955-03-09
Abstract: 775,221. Hydraulic dampers. BOURCIER DE CARBON, C. M. L. L. March 9, 1955 [March 9, 1954 ; Dec. 14, 1954], No. 6990/55. Class 108(3). The piston of a hydraulic damper comprises respective passages 21, 22, Fig. 9, for liquid flow in both directions through the piston, and controlled by valves formed by flat discs 23, 24, sufficiently flexible to flex under the pressure of liquid in the passages, the discs, the valve seats being so shaped as to provide substantially linear contact between themselves and the valves. The valve may be spaced from the seat by a few tenths of a millimeter in its " closed " position. A part of the seating may be cut away at an angle to the plane of the seating Fig. 4 (not shown), in order to provide a bleed flow through the valve. The same object may be obtained, Fig. 3 (not shown), by arranging the valve 23 or 24 so that it does not quite cover the whole of the port 21. As shown, the valves 23 and 24 are of substantially annular shape in plan view and are retained by a rigid plate 26. The latter has a projecting tongue 28 which limits deflection of the valve 23. In the construction shown in Figs. 6 and 7, a circular stack of valve discs 9, 10, and 11, control the flow through ports 1 in a laterally extending portion of the piston body 14. A second valve 9<SP>1</SP>, 101 and 11<SP>1</SP> controls flow in the opposite direction through ports 1<SP>1</SP> in a portion 16 of the piston body which extends generally at right angles to the portion 14 of the piston body. The portions of each valve which overlap the piston body portions, are supported by stops 17, against excessive deflection. When used as a vehicle damper, the diameter of the ports 1 may depend upon the ratio between the road wheel travel relative to the chassis, and the stroke of the piston 14, 16, in its cylinder. French Specification 1,020,109 is referred to.

The stator comprises legs 5, 6 and a yoke 10 fastened together by rivets 11 and energized by a coil 9 receiving pulses from the divider circuit. The circuit is on a printed board 1 carrying pins 26 connected to the coil and produces one pulse of a half second duration each second. The pinion 20 drives output shafts via gears 19 and 21-25. As shown the bearing 13 is in a recessed portion 12 of the plate 3, the other rotor bearing 15 being in a bridge 16 fixed to the plate. The portion 12 is cut away at 18 for the gear 19 and also supports a magnetically soft yoke 17 ensuring a preferential direction of rotation. Alternatively the bearing 13 is in a block (27), Figs. 3 and 4 (not shown) fixed to the plate 3 while the other rotor bearing is in the plate 4. A projection (31) Fig. 5 (not shown) on the plate 4 engages an aperture in the side plate of a chart recorder to ensure proper alignment. Various circuits for feeding alternating or unidirectional pulses to the coil are described. Fig. 6 shows a crystal oscillator 31 and frequency divider 32 the output stages 36, 37 of which operate in push-pull to pulse the coil 35. The power supply is via a protective resistor 39 and Zener diode 38. For use with a unipolar motor, one end of the coil 35 is earthed and the output stages are both connected to the other end of the coil via similarly poled diodes (40, 41) Fig. 8 (not shown). Sawtooth pulses may be applied, using a transistor circuit Fig. 9 (not shown) between the diode outputs and the other end of the coil.

Pressure and current at distant places, measuring; power meters. -In order to minimize the effect of the resistance of long connecting leads between an instrument transformer and an instrument, the secondary winding of the instrument transformer supplies the primary winding of a second or separating transformer the secondary winding of which consists of a large number of turns of fine wire. As shown applied to an ammeter indicating at a central station the current flowing in a circuit k at a substation, a measuring transformer a has its primary winding h connected in the circuit k and its secondary winding i connected to the primary winding of a separating transformer b, the secondary winding d of which is connected through leads f to the ammeter g at the central station. The secondary winding d of the transformer b consists of a large number of turns of fine wire so that the full-load current therein is of the order of 0.1 or 0.05 ampere, thereby reducing the load on the measuring transformer. Connected across the winding d is a shunt resistance c, or an inductance, or both, of such a value as to limit the voltage across the winding d to say 200 volts if the instrument circuit is opened. A gas discharge lamp e which becomes illuminated at a pressure of 200 volts may be connected across the winding d to serve as a visual signal of undue rise of pressure. The lamp e may be replaced by a spark gap, relay, bell, &c.
