Title: Preserving soln. for cut flowers - allowing transport in bud form and ripening at time of sale
Inventor: MAIA ETIENNE
IPC: A01N3/02
Filed: 1975-02-28
Abstract: Preservation of cut flowers, partic. mimosa, is effected by immersing the stems, after cutting off >=2 cms. in a soln. of a powder contg. 100mg. hydroxylamine hydrochloride, 400mg. citric acid, 20mg. benzimidazole, 100mg. 8-oxyquinoline sulphate and 10mg. of saccharose in 1 litre of water, 1 mg. of magnesium silicate is opt. added, partic. when the water is hard.

Title: High pressure discharge lamp thermal switch - has combination of bimetal element and sprung conductor of specified shape
Inventor: STUART KARL DEAN
IPC: H01H37/56
Filed: 1975-06-24
Abstract: The thermal switch for a high pressure vapour discharge lamp has a sprung conductor (24) mounted at the end of a bimetal element (21) and folded back along the same.
