Abstract: 1,144,366. Protecting plants. F. E. J. FRY. 9 Aug., 1967 [17 Aug., 1966], No. 36810/66. Heading A1E. A protective covering for plants comprises bags 14, made of translucent or transparent plastics material, partially filled with liquid, e.g. water, and supported on a frame 12. The liquid in the bags is selected having regard to the climatic conditions so that it changes from the liquid to the solid state at a temperature between the optimum temperature for the plants and lower ambient air temperature undesirable for plant growth. Another layer of bags containing a liquid of lower freezing point than water for example a water and salt solution may be supported above the first layer. A low power heating cable may be placed between the bags 14 and the frame 12. A single plant may be protected by three bags 40, Fig. 6, fused together and supported on a member 22. The liquid layers may be applied either alone or with glass to a greenhouse frame. 1,144,384. Injecting brine into meat. SLAGTERIERNES FORSKNINGSINSTITUT. 6 Oct., 1966 [6 Oct., 1965], No. 44597/66. Heading A2D. A machine, Figs. 1 and 2, for injecting brine into pieces of meat of substantially uniform shape, such as hams or flitches of bacon, comprises a lower bank of injection needles 13, mounted on a holder 8, carried on a jack 6, and an upper bank of similar needles, mounted on a holder 7, carried on a similar jack 5. Each needle 13 is connected, by a flexible tube 14, to a distributer 15, which is connected by a pipe 16, to a piston-pump 17 supplying brine. The machine also comprises a chamber, which is shaped to accommodate a piece of meat, and present it to the needles, so that they can be passed, for example, through corresponding openings in the chamber, into the meat. As shown, the chamber is in the form of a mould comprising two parts, namely, a lower part 2 and an upper part 3. A piece of meat is fed, from a roller conveyer 1, into the lower part 2 of the open mould. The upper part 3 of the mould, carried on a jack 4, is then lowered to enclose the piece of meat tightly in the closed mould. The jacks 5 and 6 are then operated to push the needles, through openings in the mould, into the meat. The pump 17 then makes a single pumping stroke to deliver a definite quantity of brine, namely the contents of its cylinder, through the needles into the meat. Each tube 14 may be dimensioned, preferably in length, so that the fall in pressure along the whole tube is greater than the fall at the discharge aperture of the attached needle, and so that the brine is shared, as desired, among the needles, and thus distributed in the meat. The jacks 5 and 6 are then operated to withdraw the needles from the meat and mould. The jack 4 is then operated to raise the upper part 3 of the mould, and the lower part 2 is then swung downwards, by a jack 9, to discharge the treated piece of meat against a plate 10, which guides the meat down an inclined roller conveyer 11 on to a discharging conveyer 12. Part 2 of the mould is then swung back into a horizontal position to receive another piece of meat. All the above-mentioned jacks may be of the pneumatic-cylinder type.
