Abstract: 1278937 Road barrier ROTAX Ltd 16 Sept 1969 [7 Aug 1968] 37654/68 Heading E2M A road barrier has a pivoted arm which may be swung into both a horizontal trafficblocking position and a substantially vertical inoperative position, the arm being actuated by one or more linear electric motors in combination with electrically operated or controlled latching means for retaining the arm in one or each position. One barrier shown has an arm 10 pivotally mounted on pedestal 13 and carrying armature plate 15 which cooperates with, and separates, two aligned, pedestal-mounted, reversible, linear electric motors 16. Latch 20 is spring-biased to engage slots 18, 19, to maintain the arm raised or lowered, and is disengaged by a solenoid energised simultaneously with the motors. In a modification the latch may engage two notches in the armature plate periphery. Counterweight 17 ensures that the arm remains raised or lowered. An alternative barrier has an arm carrying the two motors which cooperate with a pedestalmounted armature plate. When adapted to fail safe operation, the counterweight is insufficient to hold the arm raised and the latch is held engaged by a solenoid which overcomes a spring biasing the latch to the disengaged position.

Convention date, Dec. 18, 1929. [Classes 25 and 137.] In a ventilator or cowl for inducing a unidirectional flow of gaseous media by relative movement of the cowl and its surrounding media, the cowl is tapered substantially throughout its length so that the flow area increases in the direction of flow so as to effect a velocity-pressure conversion of the gaseous media passing through the cowl. A discharge cowl, Fig. 1, comprises a diverging portion 19 terminating at the bottom in a circular outlet 21 and having at the top a longitudinally extending inlet portion 15 cut diagonally at 16 and joined to a vertically extending portion 17. The inlet and the upper portion of the downtake 19 are of streamline cross section having the major axis in the direction of the wind and the front having a greater radius of curvature than the rear. Curved guide vanes 24 arranged along the diagonal line 16 of the elbow inlet serve to change the direction of the air with a minimum loss of energy and prevent eddv currents. Fig. 5 shows a similarly constructed suction cowl comprising an elbow outlet 34 of stream-lined section connected to a circular inlet 31 at the bottom by a downwardly tapering portion 33.

Abstract: 1,104,859. Knitting. PASOLDS Ltd. 26, May, 1966 [10, Sept., 1965], No. 38683/65. Headings D1C and D1K. A pile fabric is formed on a circular machine by knitting courses of two yarns in plating relationship and extending some of the sinker loops of one of the yarns and knitting intervening courses of a single yarn some of the loops of which extend over the courses containing the plated yarns such that loops of the next single yarn course are drawn through them, Fig. 1. In addition the two plated yarns comprise one of natural fibre such as cotton and the other being a crimped synthetic material such as nylon which is fed to the machine in a stretched condition such that on subsequent relaxation the natural fibre yarn forms further extended loops on the side of the fabric opposite that of the sinker pile loops. The sinker pile loops may extend over two sinkers without the intervening needle knitting either yarn. Also the sinker pile loops may be in a staggered arrangement throughout the fabric. Loop formation is achieved by needle selection obtained by the provision of pattern wheels. The sinkers are also operated selectively by pattern wheels to insure their insertion for the pile loops to be drawn over the sinker nebs.

[Also in Division F2] Apparatus for enabling automatic height adjustment of the crop collecting member of a harvesting machine, which member is height adjustable in response to actuation of a manually operable control valve in a hydraulic circuit, comprises ground engageable fingers, each articulated intermediate its ends, adapted to be mounted on the member and an actuator connected to the fingers and adapted for connection to the control valve. As illustrated the apparatus is connected to a combine harvester and the actuator is a Bowden cable. In operation the header height is preset by manipulation of the manual lever 19 of the control valve 17, and any slack in the inner cable 31 of the Bowden cable is taken up by an adjusting nut 34. One end of the inner cable is connected to a crank 29 which includes a cam 28 adapted to engage a camsurface 27 on one of the fingers. The other end of the inner cable is attached to a camplate 46, and the inner cable is tensioned by a spring 47. For automatic operation a lug 53 of a lever 50 which is pivotally mounted on the lever 19 is engaged with a recess 54 in the cam plate. Any movement of the fingers is then transmitted directly to the spool 18 of valve 17, and the height of the header is adjusted accordingly. The automatic control may be over-ridden by manual lever 19. The Bowden cable also includes an overload shock spring assembly (Fig. 5 not shown). A further manual lever (55) (Fig. 3, not shown) may be provided for table height adjustment when the automatic control is operative.

The'latter includes a chamber 13 which is filled by primary fluid by the control of a diaphragm valve 12 directly operable from the pressure determined from the constriction 3. The time-lag device 5 is connected to a pressure pulse generator 6, the pulses of which are determined by the time taken to fill the chamber 13. The pulse generator which includes a plurality of differential pistons emits pressure pulses which are transmitted to a pulse pump 8 by way of a pulse regulator 7. The pulse pump includes a diaphragm actuated plunger 22, 24 which is displaced by the pulses received to displace a quantity of oil constituting an intermediate actuating fluid which passes into an injection pump 9 having a chamber 27 surrounding a resiliently deformable tube 28, i.e. of P.T.F.E. or similar plastics material through which the secondary fluid can pass from a source (not shown). The displacement of the oil by the pump plunger 24 produces a deformation of the tube 28 causing a correspondingly metered quantity of the secondary fluid to be discharged from the tube 28, through pipe 29 to an injection head 30 in the conduit 1 to be mixed with the primary fluid flowing therein. The apparatus is intended particularly although not exclusively for injecting odorous fluid int onatural gas.
