IPC: A22C25/00
Filed: 1959-07-17
Abstract: 880,394. Fish, gutting. FISADCO Ltd. July 18, 1960 [July 17, 1959], No. 24674/59. Class 28 (3). A cod &c. pulled nose first and belly down is slit by a disc knife 15 raised up to cut through the membrane spanning the lug bones, the knife passing between the two liver attachments, and cutting the belly along its length, the guts are struck out by a revolving brush 86, a cut is made by a rotated cup shaped knife 88, Fig. 4, through the liver attachments and the gut at the throat and a final cut is made through the end of the colon at the vent by a pair of horizontal disc knives 104, Fig. 11. The knife carrier 16 and lever 23 are urged to rock clockwise about the pivot 24 by a spring 26 but is limited by a lateral stop 27. A pin 31 on a plate bolted to one of the conveyer sprockets engages a lever arm 30 to rock lever 23 rapidly to raise the carrier 16 and its knife 15 to cut through the lug bone attachment. Quickly the pin 31 disengages from the arm 30, to withdraw the knife 15 into position for slitting the belly skin only being held there by an abutment 34 while the fish is pulled along to have its belly slit. A pinion 41 slides a rack 40 parallel to the fish movement. Thickness feelers 47 on the rack 40 are spaced apart by the fish and causes the knife 15 to move down away from the vent. A sector-shaped brush 86 sweeps down the guts which remain attached at throat and vent until a cup shaped rotated knife 88 severs the gut at each of these places in timed relation to the length of the belly. Specifications 878,957 and 880,176 are referred to.

Filed: 1959-07-17
Abstract: 925,083. Extensible cables. T. G. GARCIA, J. A. M. GUNDIN, and J. L. ALVAREZ. July 17, 1959 [July 19, 1958], No. 24701/59. Class 36. An extensible cable comprises a core a of elastically extensible filaments 1 covered by a tubular sheath b of lesser extensibility and having a conductor c helically wound thereon, this conductor comprising at least one conducting filament 2 helically wound around a flexible dielectric core 3 and with an insulating cover 4. The assembly is provided with an overall sheath d which is also elastically extensible. The inner sheath b is preferably produced with helical corrugations 5 and the conductor c is provided with an additional braided covering e which fits loosely so that some of the loose material will fit into the helical corrugations to lessen any tendency of the conductor to slip upon the core when the cable is extended. The conductor core 3 may be of cotton or nylon thread, the sheath 4 of plastic and the braided coverings b, d and e of "stretch" " nylon thread. An alternative form of conductor (Fig. 6, not shown) comprises a plurality of nylon filaments each having a helical winding of tinsel thereon and laid up together with a binding of nylon thread around them. They are sheathed and covered as before. A method of making the cable consists (Fig. 7-9, not shown) in passing the core a in stretched condition through a braiding head; passing the stretched and braided core through a winding apparatus, which helically winds on the made-up conductor, whilst maintaining tension in the core by pulleys and, as the resultant cable emerges from the pulleys, releasing the tension and winding it on to a drum whilst twisting it about its axis to remove twists imparted to the core by the winding process. It is then passed under tension through a second braiding head where the outer sheath d is braided on under tension and the finished cable is allowed to relax as it emerges through the tensioning pulleys to be wound on to a storage drum.

Filed: 1953-09-08
Abstract: 725,909. Centrifugal pumps. HENSCHEL & SOHN GES. Sept. 8, 1953, No. 24822/53. Class 110 (1). In a centrifugal pump for hot and boiling liquids at a low supply head, the impeller hub i is of whorled or verticillate form so as to impart a rotation to the liquid entering the impeller h. This has the effect of mixing any entrained gas with the liquid to form small bubbles which are carried away by the liquid, thus preventing the formation of a gas core near the hub. The diameter D<SP>2</SP> of the inlet edges of the impeller blades is greater than the diameter D<SP>1</SP> of the inlet openings of the pump housing a, b. A prerotation of the liquid occurs in the annular space between these two differing diameters, producing an increase in the static pressure at the inlet edges of the blades. The pump housing a, b is contained in an outer casing c having a cover-plate d and provided with an inlet g and outlet k. The pump may be of the single-flow type.

Title: Process for making potassium sulphate
IPC: C01D5/08
Filed: 1934-08-29
Abstract: In obtaining potassium sulphate by the reaction of sodium sulphate decahydrate with potassium chloride, one or both of the initial salts are dissolved in water to obtain a low temperature solution or solutions, such low temperature being maintained during the reaction of the solution with the other dry salt or the solution of the other salt whereby potassium sulphate is precipitated.  Alternatively, a substantially dry mixture of potassium chloride and sodium sulphate decahydrate is dissolved in water to obtain a low temperature solution, the low temperature being maintained during the subsequent reaction.  According to an example, a mixture of potassium chloride and Glauber's salt is dissolved in water, the initial ingredients being at a temperature of 25 DEG  C.  The temperature falls to -4 DEG C. and the potassium sulphate which precipitates is recovered.  The mother liquor can be evaporated at high temperature to recover potassium chloride which may be used in the process.  Heat-insulating vessels may be employed so as to maintain the low temperature obtained for a sufficient time.
