Title: Liquid level indicating means
Inventor: ENGLESSON SIXTEN
IPC: G01F23/32
Filed: 1961-11-07
Abstract: 933,422. Fluid actuation of switches. FLYGTS PUMPAR A.B. Nov. 7, 1961, No. 39763/61. Class 38 (5). [Also in Groups XVIII and XXXV] In a device for indicating and/or controlling the level of a liquid in a container a hollow body which is heavier than the liquid it displaces is pendulously suspended in the container and has its centre of buoyancy offset relative to a vertical through the centre of gravity or aligned with and below said centre of gravity when hanging, so that the body takes up a given angular position when immersed in a liquid of given density, and in so doing throws an enclosed electrical switch operating an electric circuit including an audible or visual warning device when the position is assumed. Suspended from a cable 2 such that it can swing about a point near its upper end is a pear-shaped hollow body 1 consisting of three sections, a shell 3, a spacer 5, and a cap 7 screwed together. The shell 3 has mounted within it a mercury switch 8 from which conductors are led to a suitable external relay through the cable 2. Also within the shell is provided a weight 10 to displace the centre of gravity 11 laterally relative to the centre of buoyancy 12. When suspended in air the device will assume a position where the centre of gravity lays on a perpendicular dropped from the pivot point, and when immersed in a liquid will take up an angular position where the gravitational forces acting through the centre of gravity are balanced by the buoyant forces acting through the centre of buoyancy. Assumption of this attitude is utilized to operate the switch 8. Location of the centre of buoyancy 12 and the value of the buoyant force may be selected by use of spacers 5 of different sizes and the use of either semi-spherical caps 7 or discshaped caps. As an alternative to an offset weight in the shell 3 to displace the centre of gravity laterally an irregular form of shell may be used.

Abstract: 1496268 Blasting WORLDWIDE BLAST CLEANING Ltd 29 Sept 1975 [21 April 1975] 39770/75 Heading B3D A method of treating a surface 3 comprises projecting abrasive particles 7 at an inclined angle relative to the surface to abrade the surface and to cause the particles to rebound from the surface, and striking the rebounding particles 9 to throw said particles along a predetermined path 12. An apparatus for carrying out the method has an enclosure 1 formed with an opening 2 which faces the surface 3 to be abraded and has a resilient seal 6. A centrifugal blast wheel 4 projects a stream of particles 5 towards the surface at an inclined angle of between 10 and 60 degrees. The particles rebound along a path 10 and are propelled by an anticlockwise rotating brush 11 along a path 12 to a further clockwise rotating bush 13 which propels the particles along a path 15 to a hopper 14 for feeding the blast wheel 4. Rotating paddles may replace the brushes. The enclosure is made of thin gauge steel or aluminium and the housing 18 for the blast wheel is lined with manganese steel, cast alloy or hardened plate. The abrasive particles may be metal shot, slag, sand, volcanic ash, glass beads, metal oxide particles, zircon, garnet, carborundum, stone, &c. The brushes or paddles 11, 13 are driven by a belt or chain drive 25 from a drive sprocket 19, the lower brush 11 rotating at a higher speed than the upper brush 13. Three or more brushes may be arranged in series. The lower brush may contact the surface 3 or be, as shown, spaced therefrom. The resilient seal 6 may have a portion 28 adjacent a rear zone 27 of the opening formed as a resilient brush to permit the entry of fluid 29, such as air, to the rear zone 27 to remove abrasive particles which may accumulate in the zone. The air flow 29 may be produced by vacuum and proceed along paths 10 and 15. The spent abrasive falls into the hopper and foreign material proceeds along path 31 into a trough 34, where any entrained abrasive particles fall through an adjustable gate 35, the air and remaining foreign material passing along a path 36 to a dust collector. The apparatus may have a steering handle, one or more drive wheels 39 and a front castor wheel assembly 40 and operate on horizontal or vertical surfaces. The apparatus may remain stationary and treat a surface moving past the opening.

Abstract: 1,244,671. Punching apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 30 Aug., 1968 [7 Sept., 1967], No. 41414/68. Heading B4B. A cyclically operating apparatus comprises an incrementor for feeding a workpiece, e.g. a record card 14, Fig. 1, step by step through a work station, an operating mechanism, e.g. a punch 70, for performing an operation on the workpiece in the work station, a single source 52 of alternating current supplied continuously to the incrementor, e.g. a synchronous motor 20 and Geneva mechanism 12, and intermittently through a switching means to the operating mechanism, and a control system 54 including means, e.g. a voltage discriminator 94, Fig. 2, for deriving timing pulses from the source of A.C., and gating means G controlled by the timing pulses for controlling the supply of operating signals to the switching means in order to ensure that the operating mechanism is only supplied with said A.C. so as to operate on the workpiece during the same portion or portions of each cycle of the A.C., which portion or each of which portions corresponds to a dwell time of the feeding operation of the incrementor. As described, the Geneva mechanism 12 drives rolls 42, 46 which advance the card 14 step-by-step, and the punch 70 is operated when coils 61, 62 about a magnetic core 60 are energized. The Geneva mechanism is so positioned on the shaft of the motor 20 that the card is stationary when the A.C. line voltage reaches a peak or trough. At each peak or trough the voltage discriminator 94 sends a timing pulse to an AND circuit in a duo-level pre-driver 98. When a data pulse is also fed via line 102 to the AND circuit the combined pulse energizes gate G of a Triac 88 to allow current to flow via line 86 to the punch coil 62. A line 106 leading to a voltage polarity sensor in pre-driver 98 determines the polarity of the pulse to gate G so that the flow of operating signals can be made possible once every halfcycle of the A.C.
