Abstract: 1405962 Shaping magnetic cores TOLYATTINSKY ELEKTROTEKHNICHESKY ZAVOD 10 Aug 1973 37979/73 Heading B3E A device for shaping a rectangular magnetic core 6 from a circular magnetic core 3 comprises shaping jaws 8, 9 of which at least one is movable, a shaping zone 4 between the jaws in which a split mandrel 13, 14 is located to pass through the opening in a circular magnetic core, a drive for actuating the movable jaw and a guide to ensure progressive movement towards an opposite jaw, and a kinematic linkage between the mandrel and the shaping jaws so that closing of the jaws causes spreading apart of the mandrel parts. Circular magnetic cores 3 pass down a shoot 28 and the lowermost core, which is held by a hook 29, is passed into the shaping zone. The parts 13, 14 of the mandrel are in contact and the jaws 8, 9 are spread apart to accommodate the core 3. Stops 11, 12 are provided transversely between the jaws 8, 9 to limit movement of the jaws when shaping is performed. The latter involves the movement of jaws 8, 9 towards the centre of the zone to compress the core and press it against faces of parts 13, 14. The jaw movement is transmitted by shackles 22, 23 and 25, 26, Fig. 3, to respective straps 21, 24 to cause movement of the latter from the centre of the zone. This results in the parts 13, 14 separating to press the core against stops 11, 12. A calibrating mandrel 7, Fig. 1, previously removed from a magazine 48 by a pusher 49, is fed by rammer (50), Fig. 2 (not shown), to a position above the shaping zone 4. A pusher 34 moves upwardly from beneath the shaping zone to transfer the shaped core on to the calibrating mandrel. The rammer then returns to a position below the magazine 48 and upon release of the next circular core 3 by hook 29 the pusher 49 removes the lowermost mandrel 7 from magazine 48, the mandrel 7, in turn pushing the rectangular magnetic core 6 from the rammer (50). The working cycle is then repeated. The device is driven by an electric motor 52 speed reducer 53, a kinematic chain 54 for transmitting motion to the jaws 8, 9 via cranks 74, 79 and connecting rods 75, 80 a kinematic chain 56 for imparting motion to the pusher 34, a kinematic chain 57 for conveying motion to the hook 29 and pusher 49, and kinematic chain 58 for transmitting motion to the rammer 50. Chains 56, 57, 58 comprise cams 84, 85, 104 which actuate movement of levers (45), Fig. 6 (not shown), 90, 107 respectively via respective rollers 46, 89, 105. The speed reducer 53 comprises a worm 59 and worm gear 60 which carries a driving sprocket 67 of a chain drive 68 and driving gear 69 of kinematic chain 54. Driving gear 69 meshes with driven gears 70, 71 which drive shafts 72, 77 respectively for the jaws 8, 9.

Abstract: 920,525. Sodium-potassium alloys; sodiumpotassium - lead alloys; lead tetra-alkyls. ASSOCIATED OCTEL CO. Ltd. Nov. 1, 1961 [Nov. 11, 1960], No. 38844/60. Class 41. Sodium-potassium alloy is produced by electrolysis of a molten mixture comprising 45 to 65% by weight of barium chloride, 15 to 40% by wt. of potassium chloride and 10-30% by wt. of sodium chloride (preferably 50-52%, 24-27% and 22-25% respectively) and conducted at about 600‹ C. in a Downs cell of conventional construction. The alloy so produced is then alloyed with lead to prepare a sodiumpotassium-lead alloy containing equiatomic amounts of alkali metal and lead, i.e. 1 gramatom of lead to 1 gram-atom of alkali metal, by slowly stirring sodium-potassium alloy into molten lead at 400-450 C. The sodium-potassium-lead alloy in flake form is charged into an alkylation reaction autoclave together with an alkyl chloride for conversion under pressure to lead tetra-alkyl. The autoclave is operated at 70-80 p.s.i. for 1¢ to 2 hours after which the tetra-alkyl lead is recovered from the reaction mass by steam distillation. The use of ethyl chloride as the alkyl chloride produces tetra-ethyl lead and methyl chloride produces tetra-methyl lead. The sodium-potassium alloy from the Downs cell using the preferred electrolyte contains 2.3 to 2.6% by weight of potassium, and the potassium content depends on the precise constitution of the electrolyte which can generally be adjusted within narrow limits to form an alloy having the exact proportions of sodium and potassium desired. Higher potassium contents can be obtained but the efficiency of the process decreases as the amount of potassium increases. The preferred electrolyte begins to freeze at 560-565‹ C. and has a density of 2.25 gms. per c.c. at 600‹ C. and an average current efficiency of 72% is mentioned during operation of the cell.

Abstract: 1,097,048. Angular bending. HOUDAILLE INDUSTRIES Inc., Aug. 31, 1966 [Sept. 1, 1965]. No. 38945/66. Heading B3E. [Also in Division F1] A reversible rotary hydraulic motor 21, Fig. 1, for advancing a machine tool holder, e.g. the upper tool support 15 of a press-brake 10 quickly during the approach portion of the stroke and slowly during the work engaging portion through rods 17, 18 and an eccentric on the motor shaft 19 is in fluid connection with two constant delivery hydraulic pumps 24, 25 driven continuously by an electric motor 22 and arranged in parallel through separately controlled reversible spool valves 27, 28 one of which e.g. valve 28 is returned to neutral in response to the position of the motor shaft 19 and hence of the support 15 whereby delivery of pump 25 is disconnected from motor 21 which is thus reduced in speed. At the end of the approach and work-engaging portions of the advance stroke the motor shaft 19 re-opens valve 28 for effecting a quick return stroke, both valves 27, 28 having been reversed. In operation valve 27 is moved from neutral to advance position by means 29 actuated by momentarily pressing a foot lever 33 which acts through a link 35, trip dogs 38, 39, Fig. 3, a spacer 42 fast with a rotatable shaft 41, a spring-centred double bell crank 45 rotatable about shaft 41 and a link 36 connected to the spool of valve 27. Rocking of bell crank 45 closes contacts of a selector switch 55 in the solenoid circuit, Fig. 6, of valve 28 which is thus moved from neutral to advance position. Both pumps 24, 25 deliver to the motor 21. As the tool holder engages the workpiece valve 28 is returned to neutral when a main control switch 79 is opened by an adjustable portion 83, Fig. 5, of a bar 80 which follows a cam 57 carried said end of motor shaft 19 and at the end of the working stroke the spool of valve 27 is returned to neutral by the bell crank 45 being re-centred by the trip dog spacer 42 which is rooked with its shaft 41. For this purpose the end of motor shaft 19 carries an adjustable stop arm 60 which at the end of the advance stroke displaces a slide bar 63 to 65 to the left whereby a control lever 72 is rooked anti-clockwise about a pin 73 and the motion is transmitted through links 76, 77 to shaft 41. The return stroke of tool support 15 is initiated by pressing foot lever 33 which results in both valves 27, 28 being displaced from neutral to the other position and the cam means 57, 80 is so arranged that switch 79 remains closed until the end of the stroke which is thus completed at the higher speed. As shown the solenoids for controlling the spool of valve 28 act on a pilot valve 87 and the delivery of pump 24 may be in part by-passed through a solenoid valve 94 in series with a manually adjustable flow control valve 95.

[Also in Group XIII] In a thermostatic valve having a fluid-vapour thermal medium in a valve operating element, e.g. bellows connected by capillary tube to a probe, the bellows being in thermal-conducting relationship with a heating or cooling fluid, controlled by the valve, the ratios, respectively, of the volumes of the bellows and probe, which are normally substantially equal, to the volume of thermal medium is arranged so that, depending on the temperature of the valve-controlled fluid, evaporation at the surface of the thermal medium takes place either in the probe or in the bellows. When heating fluid is supplied at 30 and bleeds via 33, 34 over bellows 35, 38 the medium in 35 evaporates and condenses to fill the cold probe 37 but has its surface at a high temperature in 35 so that the vapour pressure fully opens valve 41 against temperaturesetting spring 46. The medium in bellows 38 evaporates and condenses with its surface in probe 40. Evaporation then occurs in accordance with the temperature of probe 40 and the valve 43 co-operates with its seat to control flow of heating medium in accordance with the room temperature detected by probe 40. When cooling fluid flows around the bellows, the medium condenses with its surface in 38 and the low vapour pressure allows setting spring 47 to fully open valve 43. Medium condenses in 35 with its surface in probe 37, valve 41 moves towards its seat and controls cooling fluid flow in accordance with vapour pressure in probe 37 determined by room temperature. The valves may be used separately.
