Abstract: Soil may be tested for mineral deficiencies by contacting with a device comprising a plurality of isolated zones of absorbent material, each zone carrying soil algae and a proportion of at least one nutritional compound selected from phosphorus, nitrogen and potassium compounds, each zone having a different nutritional capacity with respect to soil algae.  The phosphorus compound e.g. of concentration 0.025-0.3 mg. P/sq.cm., may be sodium or calcium superphosphates, rock phosphate or sodium hydrogen phosphate.  The nitrogen compound e.g. of concentration 0.05-0.10 mg.N/sq.cm., may be calcium cyanamide or an ammonium salt e.g. the sulphate.  The potassium compound e.g. of concentration 0.075-0.15 mg.K/sq.cm., may be potassium sulphate.  One or more trace elements i.e. Fe, Cu, Mn, Mg, Al, Zn, Mo or B may be added e.g. in the form of the iron complex of E.D.T.A., copper sulphate, manganese chloride, magnesium sulphate, aluminium sulphate, zinc sulphate, sodium molybdate and orthoboric acid.  Four isolated zones may be used in the device, the zones carrying compounds of phosphorus, potassium and nitrogen; potassium and nitrogen; potassium and phosphorus; and nitrogen and phosphorus, alternatively two or more zones may carry the same combination of nutritional compounds but at different concentrations.  Suitable soil algae are Chlorella vulgaris, Stichococcus bacillaris Homodium flaccidum and Plectoma Sp, and may be present in concentrations 10 x 1014 to 10 x 1016 algal cells/sq.cm.  The absorbent material may be paper and in the form of a flat sheet having a non-absorbent central zone and a plurality of absorbent peninsula zones extending outwardly from the outer periphery of the central zone.  An alternative design is also disclosed.  The peninsula zones may be edged in wax whilst the central zone may be made non-absorbent by impregnation with polyethylene or a silicone.  An additional absorbent zone e.g. the central zone, may be impregnated with a pH indicator for the range 5-8.  The algae may be introduced by surface, soaked or filtered impregnation.  The nutritional compounds may be added as an aqueous solution or as a concentrate to the centre of the zone and then the device may be dried, or impregnated plastic pellets from which the nutritional compounds are released slowly.  The impregnation of the algae and nutritional compounds may be done simultaneously.  The method of testing is to contact the device with a sample of soil and observe the intensity of growth in the various zones e.g. over a period of 3-6 days at room temperature in artificial light or indirect sunlight.  In a modification the soil algae may be replaced a mould such as Aspergillus niger and a source of assimilable carbon. In another modification, the device comprises a piece of absorbent paper carrying soil algae and a nutritional compound as above.

In a current limiting automatic circuit breaker the movable contact 14 and the normally fixed contact 16 are arranged to be moved in opposite directions by electrodynamic repulsion independently of the usual trip mechanism and held apart by individual overcentre springs 32, 60, the trip mechanism operating a short while later to move the contact 14 to its normal open position and to reset the contact 16 to its normal closed position. The contact 16 is mounted on a fixed pivot 44 and overcentre springs 60 act between a pin 56 on contact 16 and a pin 52 on links 46 freely pivoted on a fixed pivot 48. The contact 14 is pivoted at 22 to a carrier 24 itself mounted on a fixed pivot 26. The overcentre springs 32 act between pins 36, 40 on the contact and carrier respectively. The carrier is coupled by a conventional overcentre spring toggle linkage to a handle 82; the linkage being latched by a conventional trip unit 105 including a bimetal 108 and electromagnet 112. In the closed position springs 32, 60 provide contact pressure. On overload or excess current the mechanism acts conventionally to move the carrier 24 together with contact 14 to its open position (Fig. 4, not shown). Upon the occurence of a short circuit the electrodynamic forces between the parallel contacts 14, 16 are sufficient to throw the contact apart, the springs 32, 60 passing overcentre. Immediately after this the normal electromagnetic trip 112 releases the mechanism to move carrier 24 to the open position, contact 14 engaging a stop 28a to reset spring 32. An overhang 24b on carrier 24 engages a slide 76 freely movable in the housing; the other end of slide 76 drives the contact 16 back to its normal position.

Abstract: 1,210,194. Latches. COMPAGNIE INDUSTRIELLE DE MECANISMES. 27 Jan., 1969 [1 April, 1968], No. 4414/69. Heading E2A. In a door latch, e.g. for vehicle doors, the keeper 10 is engaged by a pawl-shaped latchbolt 4 and an anti-rattling cam or 'wedge' 6 on top and bottom sides respectively, the loading on both being provided by a tension spring 21 whose tension is increased as the keeper engages. The cam 6 also engages a recess 14 to provide an intermediate 'safety' latched engagement. The pawl 4 is of semicylindrical shape and engages keeper notches 12, 13. The manually operable lever 15 is is loaded by spring 17, and has a tab 18 engaging an arcuate slot 19 in a segment 20 secured to the spindle 5 of the pawl 4. This segment is loaded by spring 21 and when it rotates, its limb 24 engages a limb 25 on a lever 26 secured to the spindle 8 of the cam 6. Hence movement of the lever 15 against spring 21 disengages both the pawl 4 and cam 6. Closure of the door causes the keeper 10 to engage the pawl and cam simultaneously to tension the spring 2, Fig. 4. In the fully engaged position, the pawl 4 engages slot 13 and the cam 6 is rotated by frictional engagement with the keeper to an extreme position (Fig. 5, not shown). In the form shown, there is an additional 'safety' latch position 12, but in a modification (Fig. 7-12, not shown) this is dispensed with. In this form, initial entry engages the cam 6 only, further entry rotates the cam by friction as before and the spring tension turns a pawl into its latching position. The cam 6 may be of plastics.
