Title: An improved fish dressing machine
IPC: A22C25/00
Filed: 1942-02-02
Abstract: 557,099. Dressing fish. WIND, S. DE., and CRUICKSHANK, J. Feb. 2, 1942, No. 1340. [Class 28 (ii)] A fish-dressing machine comprises a heading unit for decapitating, splitting and gutting herring in one operation whilst stationary, and an independent boning unit for filleting the fish transferred from the heading unit, the two units being assembled together in a single machine. The head of the fish is inserted in an opening 64, Fig. 7, until it rests on an inclined head locator 133, Fig. 1, (shown in its inoperative position). Guides 61 centre the body of the fish with its belly towards a vertical slot 65. In effecting the operations of decapitating, splitting and gutting the fish, a handle 10 is depressed. On the initial movement of the handle the lower part of a tappet 11 permits a spring 19 to rock the head locator 133 into its inclined headsupporting position, and then by means of a telescopic spring rod 26, to close a pair of roughened jaws 37 upon the head. Further movement of the handle engages the tappet 11 with a crank pin 15 and rotates a main shaft 7 to swing a knife 46 quickly in an upward direction to slit open the belly of the fish, and to cause a pair of notched knife blades 55 to sever the head. When the handle 10 is allowed to return, the various parts resume their normal positions and the head of the fish together with its attached entrails falls out through the bottom of the machine. To perform the boning operation, the decapitated fish is inserted, shoulders first and belly upwards, through an opening 129, Fig. 7, on to a pivoted tray 67 until the shoulders of the fish rest against the apex 86a of a fixed hollow boning knife 86. A drank handle 78 is turned to rotate a serrated feed wheel 79. Cam mechanism allows the pivoted tray 67 to rise and press the fish against the feed wheel and at the same time to lift a lever 103 until the bifurcated upper end of a plate 96 straddles the boning knife 86. On further rotation of the crank handle the feed wheel forces the fish against the boning knife. The apex of the knife gouges out the backbone which passes through the hollow knife whilst the flesh passes down the lower inclined outer surface of the knife. The cam mechanism also allows the bifurcated plate 96 to descend and spread the lugs of the fish and press it into contact with a roller 95 rotated by gearing, to draw the fish through the boning unit. Continued rotation of the crank handle rocks a tail fin guide 123 and a knife 12 in a clockwise direction to guide the tail as the knife severs the backbone, allowing the backbone to travel through the hollow boning knife whilst the tail remains on the fish. During the travel of the backbone through the boning knife the curved upper edge 86b of the knife separates the finer belly bones from the flesh. The cam mechanism depresses the pivoted tray 67 and allows the filleted fish to be ejected by the roller 95 after which the mechanism returns to its starting position.

Title: Improvements in the manufacture and production of agents for combating plant pests
Filed: 1932-01-18
Abstract: Organic bases of high molecular weight, probably in part bound to carbonic acid, are prepared by heating an equimolecular mixture of formamide or ammonium formate with an aliphatic ketone, such as acetone.  The reagents are heated in a closed vessel to 150-250 DEG C., but if ammonium formate is used the temperature should be at least 180 DEG  C.  For use as insecticide soap or other wetting-agent is added, but free fatty acids, such as those of palm oil or oleic acid, may be added since these combine with the bases to form compounds with wetting properties.ALSO:Formamide, or ammonium formate, is caused to react with an aliphatic ketone, such as acetone, and the crude reaction products are mixed with wetting agents and water for use as insecticidal plant sprays.  The reagents, in substantially equimolecular proportions, are heated in a closed vessel to a temperature between 150 DEG  and 250 DEG  C.  If ammonium formate be employed the temperature must be at least 180 DEG  C.  The products are stated to be bases of high molecular weight presumably bound in part to carbonic acid.  Wetting agents specified are soap, and water-soluble salts of sulphonic acids of aromatic or aliphatic compounds containing at least 8 carbon atoms, for instance those of naphthalene, mineral oils or brown coal tar oils; or fatty acids such as those of palm oil or oleic acid may be added in the free state since they combine with the insecticidal bases to form compounds with wetting properties.

Title: Improvements relating to the production of substituted carboxylic amides
IPC: C07D295/26
Filed: 1945-01-17
Abstract: N.N-Disubstituted carboxylic acid amides are obtained by heating a carboxylic acid, e.g. at 200-250 DEG  C. with an organic sulphondialkylamide of the general formula R.SO2.N.R.1R2, where R.SO2 is the residue of an organic sulphonic acid and R1 and R2 are the same or different straight or branched chain alkyl groups including methyl groups or may together constitute a divalent polymethylene group which forms with the nitrogen atom a heterocyclic ring.  In cases when the carboxylic acid contains a ring nitrogen atom or other basic atom or group, the yield may be improved by treating either the acid alone or the reaction mixture with another acid prior to or at any early stage in the reaction with the organic sulphondialkylamide. In examples: (1) N.N-dimethylbenzamide is obtained by heating benzoic acid with benzenesulphondimethylamide; nicotinic acid diethylamide is obtained by heating (2) nicotinic acid with benzenesulphondiethylamide, (3) nicotinic acid benzenesulphonate with benzenesulphondiethylamide.  Samples have been furnished under Sect. 2 (5) of: N-methyl-N-ethylchloracetamide prepared from chloracetic acid N-methyl-N-ethylbenzene-sulphonamide; N - methyl - N - n - propylbenzamide prepared from benzoic acid and N-methyl-N-n-propylbenzenesulphonamide; N-benzoylpiperidine prepared from benzoic acid and N-toluene-p-sulphonylpiperidine.

Title: Improvements in or relating to methods of and compositions for conditioning water for steam generation or boiling
IPC: B01D19/04
Filed: 1948-01-21
Abstract: Water for steam generation is conditioned by incorporating with it a protein, tannin, alginate, gum arabic, or polyuronic acid derivative together with a surface active, predominantly hydrophobic substance the molecules of which include a group of hydrophilic radicals directly connected or spaced apart by not more than 5 carbon atoms, at least two of said radicals having attached thereto a hydrocarbon chain containing at least 12 carbon atoms.  These chains may also carry hydrophilic groups consisting of OH, OR, COOH, COR, and CHO. Soluble compounds of heavy metals particularly lanthanum and uranium, but also manganese and chromium, may also be added.  The hydrophilic groups are those mentioned in Specification 602,726 and any of the substances described in that Specification may be employed in the present invention.  Further examples are given of the acylated derivatives of ethylene diamine and polyalkyl polyamines; the acylating acids may be oleic, stearic, palmitic, erucic, linoleic, linolenic, ricinoleic, hydroxystearic, cetyloxy butyric, behenic, ketohydroxystearic, &c. and tall oil.  Also a short chain acyl group such as acetyl may first be introduced into the primary amino groups of a polyalkylene polyamine and the long-chain acyl groups then introduced into the secondary amino groups. Long-chain acyl and/or alkyl groups may also be introduced into hydroxy alkyl amines, yielding substances of the general formul  defined in Specification 602,726 and also structures such as <FORM:0631775/III/1> where Y = H or COR and x = a number of less than 15.  Imidazoline derivatives having a long aliphatic side chain and amino groups acylated with a higher fatty acid may also be used.  An example is 1 oleyl 2 stearyl imidazoline.

Filed: 1955-01-21
Abstract: 764,445. Controlling motor vehicles. DAIMLER-BENZ AKT.-GES. Jan. 21, 1955 [Jan. 21, 1954], No. 1528/55. Class 79(5). [Also in Group XXVII] In a motor vehicle in which an engine is mounted on a flexible suspension, a control member being mounted on the engine and a controlling member being mounted on the vehicle frame, a control linkage between the control and controlling members has an intermediate link arranged parallel to the natural axis of oscillation of the engine, the intermediate link being made to extend along the length of the engine to take advantage of the fact that the longer the link the less is the longitudinal displacement caused by a given angular displacement of the link. As shown, the intermediate link 18 forms part of a linkage between an accelerator pedal 22 and a throttle valve 10. The link 18 is universally jointed at its ends and is arranged parallel to and as close as the engine block and crankcase will permit to the crankshaft, which is assumed to coincide with natural axis of oscillation. The effect on the throttle of play in the joints in the linkage is avoided by having a spring 24 act directly on a lever 14 connected to the throttle, the spring being arranged to give a progressively smaller restoring couple as the throttle is opened wider.

Abstract: 909,985. Type-printing telegraphy. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 18, 1961 [Jan. 21, 1960], No. 2055/61. Class 40 (3). The invention provides an apparatus which, on reception of a randomly occurring pulse, produces a pulse at one or other of two given instants in a cycle, the instant at which the pulse is produced depending upon the time in the cycle at which the random pulse arrives. A pulse arriving at t cocks both storage pulse generators 2, 3. Clock pulses are applied at t 1  and t 7  to fire generators 2, 3, respectively, and hence the generator first fired after time t gives an output pulse. This output pulse, at t 1  or t 7  triggers a blocking oscillator 4. This in turn generates a pulse at t 1  or t 7  which fires both generators 2, 3. An embodiment in which the blocking oscillator is replaced by a storage generator is described with reference to Fig. 2 (not shown). Specifications 877,777 and 909,984 are referred to.
