Title: Fish gutting machine
IPC: A22C25/14
Filed: 1971-09-09
Abstract: 1358851 Gutting and beheading fish NORDISOHER MASCHINENBAU RUD BAADER 9 Sept 1971 [11 June 1970] 28373/70 Heading A2U Fish are gutted and beheaded in a machine having gripping means by which fish are transported past a number of operating stations, and a tool disposed at each station is arranged to move with a fish whilst performing its operation and thereafter to return to its initial position in readiness for the next fish. A rotary disc 4, Fig. 1, carries gripping means comprising a pair of flank grippers 6 and a back support 7 controlled by a stationary cam 22, the arrangement being such that a fish placed by hand between the grippers 6 at a charging station is engaged by the grippers and located radially with respect to the disc 4 by the support 7 which is interconnected with the grippers to move radially outwardly as the grippers close The grippers may be supplemented by supports (not shown) as described in Specification r.309,359 for supporting the fish behind their pectoral fins. Mounted coaxially with the disc 4 is a tool support 8 on which are carried arms 9, 32 bearing a gullet cutter 10 and a neck cutter 13, respectively, and a further arm (not shown) bearing a combined belly opener and intestine stripper. These three tools, which may be driven by individual motors, as shown, or by a common drive acting through a suitable transmission, are so mounted, as by pivots 14, 16, that they are movable, e.g. by a ram, spring or cam, towards and away from a fish being processed. Thus, as a fish reaches each operative station during rotation of the disc 4, the tools are brought into engagement with the fish, the support 8 is driven in synchronism with the disc so that the tools accompany the fish over a limited arc of movement, the tools are then retracted from the fish, and the support 8 is reversed so that the tools are returned to their initial positions. The combined belly opener and intestine stripper, which executes an upward movement towards the head of the fish during its operative period, consists of a rotary cutting disc 54, Fig. 7, or a pair of such discs mounted with their chamfers 53 facing each other, flanked by discs 61 between which and further discs 63 are spacers 60 carrying stainless steel beater blades 56 which remove the intestines.

Filed: 1950-11-21
Abstract: 681,955. Automatic regulators. BENDIX AVIATION CORPORATION. Nov. 21, 1950 [Nov. 23, 1949], No. 28452/50. Class 38 (iv). In a regulator in which a variable resistance is acted upon by the armature of an electromagnet biased by at least one curved blade spring anchored at one end to a base member on which it wraps to change its radius of curvature, and therefore its stiffness, upon movement of the armature, the base member is adjustable to vary spring stiffness. In Fig. 1, movement of an armature 17 towards its electromagnet in a carbon pile regulator of the type described in Specification 665,284 is opposed by two springs 37 rolling on blocks 38 so that the radius of curvature of the springs decreases to increase their stiffness and so produce the desired force-deflection characteristic. In the present Specification in addition to the adjustment provided by screwed union 33, the relative position of blocks 38 is adjustable by nut and bolt 45, 44 to facilitate initial setting of the regulator, after which blocks 38 are secured to a base-plate 24 by screws 41 extending through slotted holes 42. In a modification, Fig. 4, armature 17 is opposed by a spring 61, rolling on a block 49, the ends of which are relatively adjustable by a nut 59. In a further modification, Fig. 3 (not shown), a spring is connected between block 49 and armature 17.

Patent GB-354604-A (GB)
Title: Improvements in the manufacture and production of metallic cyanates
IPC: C01C3/20
Filed: 1930-09-25
Abstract: Cyanates of the alkali metals and of the metals of the second group of the periodic system having an atomic weight below 200 are prepared by converting ammonium cyanate with oxides or hydroxides of the said metals in monohydric aliphatic alcohols or liquid ammonia.  Generally the temperature should not exceed 30-35 DEG  C., but very low temperatures may be used.  The presence of small amounts, say up to 10 per cent, of water is permissible, especially when using alcohols. When preparing alkaline-earth cyanates, the use of an excess of oxide renders harmless any water present or formed in the reaction.  The cyanates can be worked up by known methods.  Examples describe the preparation of the cyanates of sodium, potassium, magnesium, calcium, strontium, barium, zinc, and cadmium.

Title: Improvements in the manufacture and production of halogenated 3.4.8.9-dibenzopyrene-5.10-quinones
IPC: C09B3/54
Filed: 1929-09-23
Abstract: Halogenated-3.4.8.9-dibenzopyrenc - 5.10- quinones are prepared by treating 3.4.8.9-dibenzopyrene-5.10-quinone or its derivatives with halogen or a halogenating agent in the presence of an organic solvent or diluent and in the presence of one or more halogen transferrers; or by treating the quinone or its derivatives in aqueous suspension or in the absence of a diluent with halogen or a halogenating agent, preferably in the presence of one or more halogen transferrers. Suitable catalysts are metals such as iron, copper and their compounds, or non-metals such as sulphur, phosphorus, and in particular, iodine.  Suitable organic diluents are halogenated and nitro-benzenes and naphthalenes.  When working in aqueous suspension the medium may be rendered slightly acid or alkaline, and the initial material is preferably treated in a finely divided condition.  When working in the absence of a diluent it is advisable to add a buffer compound to keep the reaction mixture about neutral.  The bromination by the above methods yields monobromo derivatives whereas when monochloro derivatives are to be produced the amount of chlorine or chlorinating agent should not substantially exceed theoretical requirements.  The products are uniform, dye cotton from yellow to yellow-red shades, and are valuable as intermediates.  In examples (1) 3.4.8.9 - dibenzopyrene - 5.10 - quinone is treated with bromine in nitrobenzene in presence of iodine and iron, or of iodine alone, or in the absence of a diluent and in presence of iodine, or in aqueous suspension; or the quinone is chlorinated by chlorine gas in the presence of sulphur, or by treating in nitrobenzene with iodinemonochloride, or with sulphuryl chloride in presence of iodine, or by treating in dichlorobenzene or other organic diluent with chlorine in presence of iron chloride, sulphur or other catalyst, or by treating in aqueous suspension with chlorine: (2) Monobromo-3.4.8.9-dibenzopyrene-5 - 10 - quinone (prepared by heating the quinone with 2 1/2 mols. bromine in the presence of iodine in a closed vessel) is treated with sulphuryl chloride in nitrobenzene in presence of iodine: (3) monochloro-3.4.8.9-dibenzopyrene5.10-quinone (see example of Specification 324,964, [Class 2 (iii), Dyes &c.], is treated in aqueous suspension with bromine in a ball mill: (4) monomethoxy-3.4.8.9-dibenzopyrene-5.10-quinone (prepared by methylation of the monohydroxy derivative of example 4 of Specification 324,964) is treated with sulphuryl chloride in nitrobenzene in presence of iodine, and with bromine in aqueous suspension.
