An alkali metal carbonate or bicarbonate may be included in the preparation in stoichiometric quantity relative to the copper salt. The colloidal solution, which may have a therapeutic use, may be prepared by forming an aqueous solution of a high-molecular weight substance such as peptone, gelatin, or a polysaccharide (preferably dextran) with addition of an antiseptic e.g. 0.5% phenol and dividing it into two equal parts: to one part is added a copper salt so as to obtain a concentration of 0.12-2 mg Cu/ml, and to the other part is added a stoichiometric amount of a carbonate or bicarbonate of an alkali metal and the solution is saturated with H 2 S. Both solutions are cooled to 0-5‹C for 12 to 48 hours and mixed, H 2 S being passed in to saturate the solution, preferably in an oxygen-free atmosphere. Excess H 2 S is removed by blowing in oxygen-free nitrogen or by reduced pressure. The solution is filtered, the pH adjusted to 6-7 and then made up into ampoules under nitrogen. To obtain a more concentrated solution the cupric sulphide containing excess H 2 S is divided into two equal parts: one part is freed from excess H 2 S as above, and a copper salt added while cooling to 0-5‹C in order to bring the Cu concentration to 5-10 mg/ml. To the other part a sol stoichiometric amount of an alkali metal carbonate or bicarbonate is added, the solution saturated with H 2 S, the two parts mixed while H 2 S is passed through and the mixture allowed to stand under H 2 S for 12-48 hours at 0-5‹C. Excess crystalloids in the copper containing solution may be removed prior to mixing with the H 2 S saturated carbonate or bicarbonate solution by dialysis. An alternative method of preparation is also described. The preparation may be used parenterally and particularly intramuscularly.

Abstract: 1530997 Analysis by optical methods MONSANTO CO 10 Nov 1975 [11 Nov 1974 26 Sept 1975] 46349/75 Heading G2J [Also in Division G1] The presence and/or quantity of a first material is detected and/or determined by observing the  change in optical transmission of a waveguide whose critically reflective surface bears a reagent specifically reactive to said first material. Many examples are given (i) An optical fibre was coated in polyvinyl alcohol containing sodium picrate. Exposure to CN<SP>-</SP> (e.g. aqueous NaCN or gaseous HCN) changed the transmittance of the waveguide. Adsorbed water in the coating affected the results but could be compensated for by monitoring water adsorbtion in white light and correcting for it in measurements taken in green light (the green being complementary to the coloured (red-brown) product of reaction of picrate with CN<SP>-</SP>). Alternatively the waveguide was thoroughly dried before each measurement. (ii) NH 3  detected by reaction with coating containing Fe 2 (SO 4 ) 3  # violet Fe 2 (SO 4 ) 3 À(NH 4 ) 2  SO 4 . (iii) Antigen on fine polystyrene (latex spheres adhered to a waveguide coated with specific antibody. The adhered spheres affected the light transmitting properties of the waveguide (iv) CO 2  detected by a coating containing sodium carbonate/bicarbonate bulks and methyl red  (v) SO 3  detected by a coating containing BaCl 2  (vi) Phosgene detected by a coating pdimethyl amino benzaldehyde with dimethyl aniline or p-nitrobenzylpyridine and N-benzylaniline. (vii) Tolylene diisocyanate detected by a coating containing p-dimethylaminobenzaldehyde and acetic acid (viii) SO 2  detected by a coating containing p-phenylenediamine and formaldehyde, or iodine and starch, or potassium tetrachlormercurate with pararosaniline and formaldehyde. A suitable optical arrangement is shown in Fig. 2. Light from lamp 1 is condensed by arrangement 2 and passed through a selectable filter 3. After reflection from a 45 degrees mirror an annular aperture 4 transmits a cylinder of rays which is condensed by optics 5 to a hollow cone of rays which is conducted into the waveguide via a hemisphere and central aperture 6. A detector 8 controls an operational amplifier 9 which drives a digital voltmeter 10. Arrangement 7 supports the waveguide with minimal surface contact. The critical reflective surface of the waveguide may be that between the reactive coating and the case, in which case the sensitivity is low due to only the evanescent waves being affected. Alternatively, if the refractive index of the coating exceeds or equals that of the cone, the coating/air boundary is the critical surface and sensitivity is high.

Abstract: 1447759 Cutters for rotary mowers MASSEY-FERGUSON-PERKINS Ltd 21 Sept 1973 [7 Oct 1972] 46381/72 Heading A1F A cutter 38, Fig. 2, for a rotary mower comprises a blade 40, from which projects a mounting portion 42 of circular cross section which is integral with a semi circular end piece 44. The mounting portion passes through an aperture 50 in a rotor 32 and is held in place by the end piece engaging with the free end of a resilient bar 62 which abuts a casing 52 rivetted to the underside of the rotor. The cutter is therefore free to rotate about an axis 72, whilst a chamfered region 46 on the end piece permits the blade to move in a vertical plane upon striking an obstruction. For its removal from the rotor, the cutter is rotated through 180‹ after which the resilient bar 62 may be depressed, the cutter then being drawn out through the aperture in the rotor. In a second embodiment, Fig. 5, the cutter is held on the rotor by a detachable rectangular retaining plate 92 bolted to a support plate 88. The retaining plate has a semicircular slot at its outer end which is aligned with a similar slot in the rotor, the aperture formed by the two permitting the cutter to rotate about a vertical axis 94 and move in a vertical plane upon striking an obstruction. In both embodiments, the region of the rotor surrounding the attachment point of each cutter may be inclined downwards in the direction of rotation, thus causing the blades to tilt in like manner.
