Abstract: 1488410 Oscillating table fans GEC-XPELAIR Ltd 30 April 1976 [22 July 1975] 30602/75 Heading F1C The electric driving motor 3 of a table fan is accommodated within the base 1 and the impeller 7 is rotatably supported by an arm 4 projecting from the base. The impeller 7 is carried by a mounting 6 which is pivoted at 5 to the arm 4 to enable the impeller to be set manually into any position between two extremes A and B, the motor 3 driving the impeller through either a flexible shaft 9 or a rigid shaft connected to the impeller through a gear system having its centre line on the axis of the pivot 5. The lower end of the motor shaft 11 is connected through gearing to rotate an eccentric pin 15 which engages a slot 16 in the wall of the motor stator whereby the stator is oscillated about the axis of the shaft 11. Since the arm 4 is fixed to the stator, it oscillates with the stator. The gearing includes a gear-wheel 24 carried by an arm 23 and meshing with a gear-wheel 25 on the motor shaft 11 and a further gear-wheel 26. To stop the oscillation, a button 18 is operated to pivot the arm 11, via a link 17, to a position in which the gear-wheel 24 is out of mesh with the gear-wheel 26.

Title: Method for the orientation of a continuous sheet material by means of stretching and apparatus for use in the method
IPC: B29C55/08
Filed: 1962-08-10
Abstract: 987,776. Stretching films and sheets. O. B. RASMUSSEN. Aug. 10, 1962 [Aug. 11, 19611, No. 30793/62. Headings B5A and B5B. Apparatus for the transverse stretching of film and sheet material 5, especially low pressure polyethylene or polypropylene, comprises a cross-fluted roller 6, two cross-beams 7, 8 or, alternatively rollers or rods (not shown), a pair of pulling rollers 9, 10 and a series of wheel-shaped members 11, or alternatively, ball-shaped members (not shown), which pass laterally across the film or sheet by means of an endless chain arrangement (not shown) in the direction of arrow 14. The action of the members 11 causes pressure points to repeatedly move transversely across the sheet material as the material passes through the zone, the pressure exerted being sufficient to permanently stretch longitudinally the sheet material as the material passes through the zone. Passage over the cross-fluted roller 6 causes a slight contraction of the film or sheet over the top of the flutes causing the formation of a series of short slipping lines 12 at about 45 degrees, and a slight pleating as indicated by lines 13. The wheel 11 displacing the sheet downwardly between the beams 7 and 8 causes local stretching and smoothing which spreads sideways in the direction of arrow 14 as the wheel passes across. When the wheel has passed the sheet or film returns to the original level and simultaneously, owing to the distension, a fine longitudinal pleating will be formed continuing across the beam 8. The original slipping line system now forms a dense pattern 14 which disappears together with the fine pleatings during a subsequent longitudinal stretching in known manner. In a modification, a pleating apparatus may be included following the cross-fluted roller. The apparatus is suitable for the cold-stretching of film or sheet material, especially of low-pressure polyethylene or polypropylene and for the preliminary treatment of film and sheet material which is to be used for producing fibres by splitting.

[Class 106 (ii)] ' The instrument is intended to indicate the maximum value of a fluctuating pressure and is constructed so that there is interposed between the fluid the pressure of which is to be measured, a liquid that acts as a transmission medium and which is isolated from direct contact with the pressure fluid, means being provided to prevent movement of the liquid away from the gauge proper until operation of a releasing device. The gauge proper 1 is connected by an adapter 4 to a hollow column or handle 5 provided with a houk 25 to hook under a pin 26. on an adapter 24 connected to an engine and upon which the device seats at 23. The part 21 contains a bellows 17 which is acted upon by pressure fluid from the engine. The bellows 17, passages 19, 6 and the gauge 1 contain liquid such as oil or glycerine. The pressure acting on the bellows forces the liquid past a non-return spring pressed ball valve 8 through constriction passages 12 to the gauge in which the pressure builds up until maximum pressure is indicated. To release the liquid, a spindle 31 with a knurled head 38 is pushed in the cam end 32 of the spindle pushing the ball from its seat. In a modification a long rod extends through the passage 6 into the bellows 17 which under the pressure in the bellows is forced up to transmit the pressure to the liquid in passage 6 and hence to the gauge. The rod is gripped by a spring pressed one-way ball and cone clutch which holds 'it in the highest position reached. The clutch is released by turning a spindle from outside the device, a cam end on the spindle lifting a sleeve to push the balls of the clutch towards the broad end of the cone, thus releasing the rod.

In manually-controlled apparatus for regulating the magnitude and direction of thrust produced by two propulsion units H 1 , H 2 , Fig. 6, when manoeuvring a floating structure, e.g. a ship (N), Fig. 1 (not shown), or an offshore drilling platform, two rotatable control elements comprising cylinders 16, 17, Figs. 4 and 5, are coupled with arms 9, 10 on a shaft 8 that is movable both axially and rotatively and is connected to manual control levers or handles L 1 , L 2 , said elements being connected to electric motors (not shown) through synchro-systems T 1 , T 2 , Fig. 6, which motors effect angular displacement of the propulsion units about vertical axes V 1 , V 2  so as to vary the directions of the thrusts developed thereby. The units aforesaid include propellers that are driven by motors M 1 , M 2  whose speed and direction of rotation is regulated by mechanical or electrical devices b 1 , b 2  coupled to the terminal ends e 1 , e 2  of sleeves m 1 , m 2 , which are slidingly lodged within the cylinders 16, 17, respectively, and attached to annular members 30, 31 that engage with bell-crank levers 20, 21 pivotally connected to the arms 9, 10 by shafts 26, 28 extending through elongate diametral apertures 18, 19 in the cylinders 16, 17. Gearing 32, 33 connects the cylinders 16, 17 to synchro-transmitters 34, 35 in the systems T 1 , T 2 . The shaft 8 is connected by an internally-splined rotatable sleeve 13 to an element 4 carrying the handle L 2  and mounted on a rotatable shaft 3 that pivotally supports the handle L 1  in a U-shaped member Z, a block 1 at the lowermost end of the latter handle being pivotally attached to a rod 14 that is connected to the shaft 8 by a ball-andsocket joint 11. The sleeve 13 is coupled to the shaft 3 by links 13 so that it rotates in unison with therewith. In operation, the handle L 1  can be moved in any of four directions B, T, AR, AV, or any direction intermediately thereof, to effect corresponding movement of the levers 20, 21 and rotation of the cylinders 16, 17, and thereby cause displacement of the ship in an analogous direction. Movement of the handle L 2  in either of two directions B<SP>1</SP>, T<SP>1</SP> causes the ship to turn about a vertical axis passing through its centre of gravity (O). In a modification, Fig. 8 (not shown), the handle L 2  is replaced by a wheel connected to a pair of shafts carrying the arms 9, 10 by gearing (41, 42, 43), the shaft 3 and the sleeve 13 being coupled to each other by a chain-and-sprooket system (36, 37, 38).
