Title: Apparatus for manufacturing sausage
IPC: A22C11/00
Filed: 1971-08-17
Abstract: 1311443 Sausage manufacture G KOLLROSS 17 Aug 1971 [15 May 1971] 38491/71 Heading A2B An apparatus for the manufacture of sausages is provided with nozzles having axes parallel to each other and perpendicular to the plane of a circle and spaced apart on the circle, these nozzles being movable about a circular path to the outlet of a filling machine, wherein a squeezing and clip applying device is movable in a direction parallel to the axis of the circular path between release and working positions and is connected to an abutment such that when in the working position, the nozzle to be filled is pressed by the abutment against the outlet of the filling machine. A suitable apparatus is shown in Fig. 1 wherein nozzles 36 are mounted on the disc 32 and by rotation of this disc can be aligned with a fixed filling tube 40 of a filling machine 52 (Fig. 4, not shown). The device 22 which contains drawing up and clipping devices, may be subjected to a reciprocating motion to and from the nozzles by the power drive 26. The bend-resistant arm 114, attached to the device 22, is provided with an adjustable screw 116 which contacts the disc 32 when 22 is brought up into contact with the nozzles. By this means leakage of sausage meat during filling is reduced. There is also provided a casing retainer or brake 64 (Fig. 3, not shown) to grip the casing about the nozzle. Movement of disc 32 is controlled by the means shown in Fig. 5 wherein there is fixed on disc 32 a ratchet plate 92 have recesses 94 corresponding in position and number to the nozzles 36. A drive pawl 98 engages recesses 94 and thus activation of power drive 102 will rotate the plate 92 and hence 32 through the angle separating two adjacent nozzles. This rotation ceases due to the disengaging of pawl 98 from recess 94, the pawl returning to the position shown in Fig. 5. To reliably entrain the disc 92 upon return travel of pawl 98 and to accurately align nozzle and filling pipe, the shaft 30 is fitted with a locking disc 104 with wedge shaped recesses 106 to engage end 108 of the lever 110 which is activated by power drive 112. Operation of the various power drives may be arranged to be inter related.

Abstract: 843,902. Inserting wires into sockets. PLESSEY CO. Ltd. Nov. 28, 1958, No. 38555/58. Class 108(3). A device for threading insulated wires into an elastomer block comprises a chuck having steel jaws 1, the leading portions of which form a mandrel 4. In operation, a knob 15 is first moved towards a handle 16, from the illustrated neutral position, to open the chuck. A wire is then placed into the mandrel from the side opposite to a cam lever 11, and the knob 15 is pushed away from the handle to close the chuck. A narrow portion 7, of a bore 6 will then firmly clasp the wire whereupon the wire and the mandrel 4 are pushed into the hole of the elastomer block. The knob 15 is then pulled towards the handle, forcing the jaws 4 apart against the resistance of the elastomer block, whilst the wire is retained in the hole by the friction of the elastomer block. The mandrel is now withdrawn from the hole. Wires attached to socket pins or socket bushes may also be inserted into an elastomer block as described above.

Abstract: 1422747 Making cylindrical shells; tube expanding; shearing GROTNES MACHINE WORKS Inc 17 Aug 1973 [8 Sept 1972] 39031/73 Headings B3A B3J and B3W A metal cylindrical shell 10, for example, for making vehicle wheels, is made by forming a pipe 22 and cutting off the free end of the pipe while the pipe is being continuously formed. The pipe 22 is made by helically winding metal strip 16 fed to a welding head 24, e.g. electron arc welder, and a weld bead trimmer 26. The cutting off is effected by an expandible segmented die 28 mounted on a rod 30, Fig. 3, for movement with the formed tube. The die segments have a cutting edge 40 and also shape the cut-off shell. The die is expanded by a tapered mandrel 42 advanced into the die as the front end of the pipe is above the roller conveyor 48. After the cutting off and expansion of the shell the mandrel 42 is rapidly retracted and the die contracts and is moved into the pipe to release the shell 10.

Abstract: 1493728 Electroslag refining CENTRO SPERIMENTALE METALLURGICO SpA 2 Dot 1975 [11 Oet 1974] 40254/75 Heading B3F A method for the electroslag refining of metals comprises ascertaining the amount of thermal energy generated in the refining operation by measuring the rate of heat absorption by a coolant passing through a mould in which the operation is effective, and controlling the refining operation in dependence on the rate of heat absorption. In apparatus for carrying out the method, a lining 2 is produced on a metal object 1 having a higher melting point than the metal applied. The apparatus consists of a T-type or rectangular profile mould 3 which is vertically movable. A coolant is circulated through a number of zones 4a ... 4d of a coolant jacket, the zones being defined by a helical baffle 5. Each zone incorporates a thermocouple 6 connected to a recording circuit. The heat absorption in the zone 4c level with the molten metal 9 is higher than in the zone 4b level with the molten slag 7 and where the heat absorption will be proportional to the rate at which power is supplied to the electrodes 8 and in the zone 4d where the heat absorption gradually decreases due to the thickness of the solidified slag formed on the layer 2 and mould 3. The output from the thermocouples indicates the level of the molten metal, the height of the slag above the molten metal, variations in the thickness of the solidified slag, and the rate of refining, and permits optimum adjustment of the power supplied to the electrodes, the rate of movement of the mould and the rate of flow of the coolant. The mould is moved at a substantially constant speed in dependence of the rate at which the electrodes are consumed, the electrodes being moved downwardly to maintain a constant degree of insertion in the molten slag.

IPC: C01B25/234
Filed: 1964-10-08
Abstract: An aqueous solution containing both phosphoric and nitric acids is extracted with a poorly water-miscible aliphatic ketone or ether having from 4 to 13 carbon atoms, the concentration of the starting solution and the weight ratio of the starting solution to the extracting agent being selected so that at least 90% of the nitric acid but not more than 10% of the phosphoric acid passes into the organic phase. The starting solution preferably contains at least 40%, but not more than 75%, by weight of water.  When the starting solution contains from 40% to 70% by weight of water, the weight ratio between the acid solution and the ketone or ether preferably is kept at from 1: 1 to 1: 3, a higher proportion of extracting agent being favoured for more dilute solutions.  The extraction either may be performed batchwise in one or a plurality of stages or may be carried out continuously with countercurrent flow of extracting agent and acid solution.  The ketone or ether may be diethyl ether, diisopropyl ether, dibutyl ether, diisoamyl ether, methyl-isobutyl ketone, methyl-isoamyl ketone, butyl-ethyl ketone, diisobutyl ketone or dibutyl carbitol; the preferred extracting agent is methyl-isobutyl ketone.  The above separation process may be applied in the recovery of phosphoric acid from the liquor resulting from the decomposition of phosphate rock by concentrated nitric acid. Such a procedure, an example of which is fully described and illustrated in the Specification, may entail preparing an aqueous solution of phosphoric and nitric acids by decomposing phosphate rock with nitric acid having a concentration of at least 45% by weight acid, lowering the molar calcium oxide/phosphorus pentoxide ratio of the solution to below 1.5 by cooling to remove calcium nitrate, subjecting the solution to an extraction with a butyl or amyl alcohol, freeing the resulting acids-containing organic extract from residual calcium nitrate by washing with a solution containing phosphoric acid and possibly nitric acid and having a concentration of at least 25% by weight total acid(s), washing the acid-washed organic extract with water in an amount such that not more than three quarters of the total acids present passes from the organic extract to the water, and separating the phosphoric acid from the nitric acid in the resulting aqueous acid solution by the extraction process described previously.
