Title: Improvements in or relating to wire tying machines
IPC: B65B13/28
Filed: 1944-09-14
Abstract: 615,617. Twisting wires together. STEVENS, A. H. (Gerrard Steel Strapping Co.). Sept. 14, 1944, No. 17607. [Class 83 (iv)] [Also in Groups I and XVII] Shearing-adjuncts.-Relates to an automatic wire-tying machine (see Group I) of the type in which a wire is looped about an article to be bound, drawn taut under tension, twisted to form a tie, and cut beyond the ends of the tie to remove the surplus end portion and disconnect the tied portion from the supply. The twisting mechanism comprises a radiallyslotted pinion 79, Fig, 32, which is journalled in a two-part casing 273 between holding yokes 80, and is rotatable through reduction gears 81, 82, 83, Fig. 12, from a sector-shaped gear 84 on a camshaft 85, the length of the tie being determined by replaceable filler blocks 86. Beyond the yokes, two adjustable cutters 87, Fig. 11, each adapted to sever only one of the overlapped wire portions, are secured to L- shaped holders 88, the lower ends of which engage laterally-elongated slots in a slide plate 89 operated by a cam-follower 90 from a grooved cam 91 in the cam-shaft 85. Immediately beyond the cutters 87 are two sector-shaped plates 92, Fig. 34, provided with wire-holding and wire-ejecting fingers 93, 94, and secured to a rockshaft 95 having a pinion 96 meshing with a rack 97 on a lever 98 which is adapted to be rocked to rotate the pinion by means of a cam and follower device driven from the camshaft 85. The wire is drawn from a supply by feed rolls 46, Fig. 2, and passes through a flexible tube and thence to a looped track 39 surrounding the article to be bound. The leading portion of the wire, after it has been fed around the track 39, is carried by a gripper 160, Fig. 32, to a position overlapping that portion of the wire entering the track, and the two portions are then urged by the finger plates 92 into the slots in the twisting pinion 79 and yokes 80. With the leading end of the wire held by the gripper 160, the wire feeding rolls are reversed so as to strip the wire from the track and tension it around the article. The sector gear 84 is caused to rotate the twisting pinion 79 through three complete revolutions and part of a further revolution in order to set up an over-twist in the tie, after which the pinion is returned through part of a revolution to bring the slot into its original position. The cutters 87 are then operated by the cam 91 so as to sever a single strand of wire at each end of the tie, and the finger plates 92 are swung forwardly in order to force the completed tie away from the twisting pinion and yokes. Specifications 615,657 and 615,658 are referred to.

Title: Apparatus for determining the content of paramagnetic gases in gas-mixtures
IPC: G01N27/74
Filed: 1951-07-25
Abstract: <PICT:0704563/III/1> <PICT:0704563/III/2> <PICT:0704563/III/3> In apparatus for determining the content of a paramagnetic gas (e.g. oxygen) in a mixture, the gas is passed through the circular poles 3, 4 of a horseshoe magnet (Figs. 1, 6) surrounded by an annular concentric heating wire 19 wound as a toroid on a glass ring 2 and connected with resistances 16, 17, 18 and rebalancing potentiometer 21 in a battery energized Wheatstone bridge having an unbalance instrument 22.  The paramagnetic gas constituent is urged by the field towards the centre of the gap where the field is strongest, to set up an area of increased gas pressure and consequently a flow of paramagnetic gas past the annular wire heated by the bridge current. The resultant cooling effect varies the wire resistance to unbalance the bridge so that the indication of instrument 22 is a measure of the parmagnetic gas content in the mixture.  External temperature changes are compensated by replacing resistance 18 by a second heating wire 23 located between unmagnetized pole faces.  The heating wire may be wound diagonally over and through a hollow former defined by four concentric parallel rings 5, (Fig. 2) on projections at the inner ends of rods projecting inwardly from a ring Fig. 3 (not shown), or on a skeleton drum comprising two parallel concentric rings connected by cross pieces Fig. 4 (not shown).  A wirewound spiral may be coated with silicon varnish or quartz or inserted in a capillary with which it is fused and bent into a circle.  The measuring device may be surrounded by a wire gauze guard and enclosed within a chamber having a gas inlet and outlet shielded from the gauze surface by baffle plates Fig. 5 (not shown).

Title: Improvements in and relating to servo-motor controlling systems for vehicles, such as aircraft
IPC: B64C13/00
Filed: 1940-12-20
Abstract: 545,296. Fluid-pressure servomotor control systems. SPERRY GYROSCOPE CO. Dec. 20, 1940, No. 17954. Convention date, Dec. 21, 1939. [Class 135] [Also in Group XXXVIII] A control system for vehicles such as aeroplanes or motor cars comprises a servomotor adapted to operate a controlled member put into operation by the initial movement of a floating lever through which power is transmitted to the controlled member. In the form shown in Figs. 1 and 3 the actuation of an aeroplane control surface such as a rudder, is assisted by an opposed pair of single acting cylinders connected to the surface by a floating bell-crank lever 9 and link 22. The longer arm of the bell crank is connected by a link 4 with a manually actuated control lever or an automatic pilot while the shorter arm is pivoted to a member slidably mounted on a link 11. The link 11 and a similar link 21 connect two similar bell crank levers 12, 13, the lever 13 being mounted on the spindle 14 of a rotary control valve, Fig. 3, for the power cylinders. During continued displacement of the load element the floating bell-crank lever undergoes bodily displacement parallel to itself, whereas rotary displacements of the lever actuate the control valve. In a modification the proportions of the bell crank levers are altered and the floating lever is linked to a manually-actuated tubular member slidably mounted on the link 22. A pin and slot connection is provided between the tubular member and the link adapted to be locked by a V-shaped slot in a sleeve rotatably mounted on the tubular member. The sleeve is rotated by a handle and is connected by gearing with a valve adapted to connect the two power chambers to permit direct hand operation of the control surface. In another form the two ends of the shorter arm of the floating bell-crank are linked to a bell-crank in turn connected by a pair of links with a crank arm actuating the control valve. In still another form the shorter arm is fitted with a toothed quadrant loosely engaging an elongated pinion. In the form shown in Fig. 11 a pair of coaxially mounted drums 70, 71, are connected by cables 72, 73 to the controlling and controlled members respectively. A lever 76 pivoted at 74 to the drum 70 and at 75 to the drum 71 is secured to a shaft 77 rotatably mounted in a sleeve 78 carried by a sleeve 79 in the boss of the drum 71. The lower end of the shaft is fitted with a crank arm, coupled by a link 87 to a sliding member formed with collars engaging a lever 89 coupled to the controller 85 of an electric motor 81. This motor is connected by toothed gearing 82, 83 with a hub 84 pinned to the sleeve 79.
