Abstract: 219,108. Nash, A. April 24, 1923. Sampling liquids.-The device comprises an open-ended cylinder, which, on the suspension cord being jerked is adapted to fall over a cylindrical framework and abut against a horizontal base-plate which closes the lower end of the cylinder trapping within it a sample of the liquid at the particular depth to which the device is immersed. The cylindrical framework is made up of a base-plate D<2>, a horizontal plate F and a top plate D<1>, the plates F dividing the framework into equal upper and lower chambers of which the cylindrical side of the lower chamber is cut away to about four-fifths of each quarter of the circumference. The upper chamber is composed of a semi-cylinder together with the top plate D<1> and the plate F. The open-ended outer cylinder C has extensions B which are bored to take the ends of a spring A attached at K<2> to the suspension cord K<1>. An extension of the cord is passed through and knotted below the plate D<1>. The plate F is provided with a hole fitted with a hinged cover which mav be secured by a catch, and a hole M is provided to accommodate a thermometer, the bulb of which dips into the lower chamber. In use the ends of the spring are inserted in the holes in the projections B and the device is lowered into the liquid, the weight being taken at the knot K<2>. When the required depth is reached, the ends of the spring are jerked out of their holes and the cylinder C falls on to the base plate, trapping liquid in the lower part of the inner structure, the weight of the device being taken by the knot K <4>.

The apparatus is used for the remote control of luminaires Fig. 1 (not shown) in a television studio, each group of stores corresponding to a particular luminaire and the input devices corresponding to the pan, tilt, focus, vertical and horizontal beam width and brightness settings being provided in a model luminaire Fig. 2 (not shown). A luminaire is selected by selector 82 and under normal conditions an error detector 78 is used to reset the input devices in the model in accordance with the actual settings of that luminaire; when an operator moves an input device, this is detected by a corresponding proximity detector P.D. and the detector 78 changes the control signal in the corresponding store in buffer store 76 and thereby alters the luminaire setting in accordance with the model. When all the luminaires have been set to a desired condition, a record of this may be transferred from a core store 75 to a file store (not shown) for subsequent use, as disclosed in Specification 1171916.

Valve 21 is normally closed and is associated with operating device 22 which is automatically actuated by fire detectors 23, 24 and control unit 25, and with operating device 28 which is actuated by manual operation of switch button 29. Unit 25 may include a timer to close valve 21 after a predetermined period. Check valve 33 is provided upstream of nozzle 35 and one-way vent valve 38 prevents overpressurising of tank 17. Ullage 16 contains fuel vapour, oxygen from the atmosphere or released from the fuel, and possibly gaseous N 2 . If the O 2  content exceeds 11% and ignition of the ullage gas occurs, detectors 23, 24 open valve 21. Liquid N 2  is sprayed from nozzle 35 in droplets and on vaporising dilutes and cools the ullage gases to the point where combustion stops. Valve 21 can also be opened by button 29 if manual control is required. Conduit 15 is chosen with diameter and length to ensure that N 2  reaches nozzle 35 at least partly in liquid form.

[Also in Divisions F3 and G2] Apparatus for collecting specimens of material from the floor of a body of water comprises a pair of jaws 5 and 6 to gather the specimens, means to cause the jaws to close on reaching the floor, ballast means 12, 13 supported on the jaws to cause the apparatus to descend, and released in response to the closing of the jaws, and buoyancy spheres 9-11 to return the apparatus to the surface upon release of the ballast means. Each jaw is pivoted at 78 or 94 on the base and comprises a pair of side plates with knife edges 71, 92, cutter 80 or 90 and a back composed of a metal plate or of a flexible sample retaining bag 98 or 101 of an imperforate Qr mesh material: Resilient bands 103-105 urge the. jaws into the closed position. When the apparatus reaches the floor cables 127 and 129 which normally hold the jaws in open position are released by cup 123 connected to the buoyancy spheres 10, 11 being urged downwardly due to the momentum of the spheres. The buoyancy sphere 9 comprises a pair of hemispheres of glass or transparent plastic and contain a camera (see Division G2) to take a photograph of the floor. When the apparatus reaches the water surface a smoke and flare assembly 14 (see Division F3) is actuated. Alternatively a radio transmitter may be used. The spheres 10, 11 may be braced or contain low density liquid or be replaced by a sphere of a plastics material impregnated with gas or containing air cells.

Abstract: 1,249,845. Irrigation. C. B. INGRAM and L. E. WATSON. 9 March, 1970 [20 March, 1969], No. 11263/70. Heading AID.  A roll-type irrigation device comprises selfrighting riser-drain units 18 mounted on a rollpipe 12 to which, at intervals, ground wheels 16 are attached. The units 18 may comprise two semi-cylindrical sleeve parts 20 capable of being bolted together. A flexible seal 24 prevents water from seeping out through the annular gap between sleeve 20 and pipe 34 so that water passes through the holes 46 into the space 22 and out through the riser 40 and sprinkler head 42 to the land. The units 18 are provided with rollers 26 which engage on the upper part of the pipe 34. A mass 56, secured by arms 58, ensures that the unit is correctly aligned (with the riser vertical) as the pipe 12 is rotated. When the water supply is turned on the resilient head 54 of the drain valve 52 is pressed against the drain port 50, blocking it. Lack of water pressure allows the head 54 to resume its relaxed shape so that water flows from the pipe 12 facilitating its movement to another station.

A variable hydraulic pump 1 and motor 2 provide a variable ratio drive to the wheels of a tractor which is rendered ineffective on occurrence of draft overload by movement of a draft-responsive member 20. The latter is loaded by two springs 22, 29 so that it may respond to changes either in tension or in compression in the top link of a three-point linkage, the changes actuating a plunger 14 through links 17, 18 forming a toggle. A spring-loaded member 25 connected by a link 24 to the pivot between the links 17, 18 may. be adjusted by a handwheel 27 to vary the degree of overload necessary for the plunger 14 to open a spring-loaded valve 10 in the supply line 3 between the motor and pump. Pressure from a priming pump 5 holds the valve open until a manually operable valve 8 connects the pump 5 to a by-pass 9 when the valve 10 is closed by its spring and the valve 8 is re-opened to prime the hydraulic circuit so that the motor 1, and hence the tractor, may be driven in reverse to clear the obstruction responsible for the overload.
