Title: Improvements in or relating to a removable sealing closure
IPC: B65D39/12
Filed: 1948-05-13
Abstract: 638,258. Tank closures; stoppers. GOODRICH CO., B. F. May 13, 1948, No. 13139. Convention date, Aug. 7, 1947. [Classes 21 and 125(iii)] A removable closure, e.g. for fuel tanks, bottles or jars, comprises an annular resilient body 13 which is closed in the middle by means 26, 30 which compress it axially and thereby expand it laterally to make the seal against the mouth of the vessel, the body being formed with a groove or grooves 22, 23 separating the sealing part 20 of the body from a part or parts, 19, 21 which act to lock the closure against displacement in the mouth of the vessel. The grooves 22, 23 are vented by grooves 24, 25 to avoid suction effects when closure is to be removed. The lower annular faces of the parts 19, 21 and, if desired, the part 20, are outwardly and upwardly inclined so that, when the distortion of the body 13 brings the parts into contact with the mouth of the vessel, any tendency to displace the closure outwardly would be resisted by further distortion of the body 13, the inclined annular faces being brought into perpendicularity with the surface of the mouth. The upper plate 30 rests upon the margin of the mouth opening, and is dished and apertured to receive a cam and cam lever 36, 37, which are pivoted to a central post 28. A washer is interposed between the cam and plate 30. A bar and chain 42, 43 prevent loss of the closure when the latter is removed from the vessel.

Patent GB-1194641-A (GB)
Title: Improvements in Load Handling Apparatus
Inventor: PRESTON HERBERT STANLEY
IPC: B65G1/08
Filed: 1968-03-19
Abstract: 1,194,641. Roller conveyers. RUBERY, OWEN & CO. Ltd. 8 May, 1969 [19 March, 1968], No. 13207/68. Heading B8A. In a live storage system, the downward movement of articles on an inclined roller or wheeled track is controlled by a member 21 attached to a cable 19 paid out by a winch 18. The member 21 is a latch mechanism comprising a plate 23 slidable in a base 22, the slider 23 having a rectangular opening 29 in which a limb 28 of a latch member is normally located. The latch member, which also includes a limb 27, is pivotally mounted on the base 22 and may be retained in the position shown in Fig. 4 by a joggled plate 31 carried by the slider 23. A stop plate 36 on the slider is able to pivot only such that its upper end moves away from the limb 27 of the latch member. The slider also carries an abutment 39 adjacent the end 38 of the base 22 to which the cable 19 is attached. The latch mechanism 21 is guided in a channel 15 between the rollers or wheels 13, 14 of the track, and in a channel 16 of a fork lift truck 12. When a pallet 11 is raised by the truck forks 17, the mechanism 21 is in the guide 16, the latch member limb 27 engages behind the pallet and, as the pallet is placed on the track, the latch mechanism passes into the guide 15. As the pallet approaches its stored position, the stop plate 36 engages an abutment at the lower end of the track or a pallet 10 already on the track and moves the slider 23 towards the upper end of the latch mechanism. The plate 31 is thus moved clear of the limb 28 of the latch member which swings out of engagement with the pallet as the latch mechanism is retracted by reversing the winch. At the same time the stop plate 36 can swing over to clear the pallet. As the mechanism returns to the top end of the track a striker (not shown) on the truck channel 16 engages the abutment 39 on the slider which moves to cause the joggled plate 31 to reengage the limb 28 of the latch member. The latch mechanism is then ready for engagement with another pallet. In a multiple storage system, Fig. 7, rails 40 extend along the upper ends of all the tracks and a powered trolley 40 for feeding a row of tracks has a winch 45 for actuating the latch mechanism cable. If means are provided for moving a trolley vertically as well as horizontally a single trolley may be used for any track in any row. The latch mechanism may be replaced by a gripping device which incorporates magnetic or suction means which is de-energized to release an article.

Filed: 1961-04-12
Abstract: 1,001,264. Lawn-mowers. RANSOMES, SIMS & JEFFERIES Ltd. April 3, 1962 [April 12, 1961], No. 13237/61. Heading A1F. A mowing machine comprises two spaced side plates 1 which provide mountings for a bottom cutting blade 3 and a rotatable cutting reel 5 extending between the side plates, a mounting for a shaft 21 which extends transversely with respect to the side plates and carries on each end a crank arm 22 on which is mounted a wheel disposed outside the side plate, and means whereby the orientation of the shaft relative to the side plates may be readily adjusted, whereby the height of cut of the blade 3 is altered by adjustment of the vertical distance between the axes of the wheels and the blade. Lever arms 25 extend upwardly from the shaft 21 and support a block 26 with a threaded bore 28 in which engages a rod 30 with handle 31, rotation of which moves the block 26 along the rod 30 thereby rotating the shaft 21 causing the side plates 1, and therefore the blade 3, to be raised or lowered. The cutting reel 5 is supported in bearings on arms 9 pivoted to the side plates, a screw member 14 extending through the arm 9 so that the position of the reel relative to the blade 3 may be adjusted. In a further embodiment frame members 60 by which the machine may be coupled to a tractor are secured to each side plate and support a shaft 62 coupled with the wheel-supporting arms 22. A shaft 64 extends through an aperture 63 in one arm 22 and is attached to a disc 68 formed with a boss 73 having radially extending bores engageable by a bar 75 to rotate the disc 68. Rotation of the disc 68 moves the shaft 64 in a circle to rock the arms 22 about the axis of shaft 62, thereby causing the members 60 and hence the cutter reel and blade 3 to be raised or lowered. The machine is preferably coupled to a tractor as disclosed in Specification 1,002,141.

Abstract: 1,189,083. Measuring density of a gas. O. KRATKY, H. LEOPOLD, and H. STABINGER. 19 March, 1968 [21 March, 1967; 4 Aug., 1967], No. 13242/68. Heading G4H. [Also in Division G1] The density of a gas is determined by measuring the resonant frequency of oscillation of a cantilever supporting hollow mass containing a known volume of the fluid. In Fig. 1, a glass sphere 1 is supported by tubular springs which also serve as inlet and outlet connections for the gas under test. A rod shaped permanent magnet 8 is mounted on the cantilever coaxially with pick-up and drive coils (9, 10, Fig. 3, not shown) connected to a direct coupled differential amplifier (11) for maintaining oscillations. The amplifier may have amplitude limiting diodes (12, 13, Fig. 4, not shown) to limit the exciting current and therefore of the mechanical oscillations. The oscillation frequency is determined by counting the number of fast clock pulses which occur while a preset number of oscillations from amplifier 11 are being counted, Fig. 6. The signal from amplifier 11 is fed via AND gate 24, opened by manual setting of flip-flop 23, Schmidt trigger circuit 25 to a multivibrator 26. The output from the latter circuit is fed both to a preset counter 27 and to a flip-flop 28 which causes an AND gate 31 to be opened to allow pulses from oscillator 29 to pass to a counter 32 having a neon display 33. When the preset number of pulses from multivibrator 26 has been counted by counter 27, it emits a pulse resetting flip-flop 34 which causes flip-flop 28 to the reset closing gate 31. The number of pulses indicated at 33 is proportional to the frequency of the input signal from amplifier 11 and therefore indicative of the density of the gas. Two or more density determining oscillators may be connected alternately to one frequency determining circuit.
