Title: Method and apparatus for making terminals and for attaching the same to conductors
IPC: H01R43/048
Filed: 1970-11-02
Abstract: 1275497 Making terminals; jointing by stamping; shearing; punching; angular bending GENSTAPE Inc 2 Nov 1970 [3 Nov 1970] 51984/70 Headings B3A B3E B3Q and B3W Electrical terminals are stamped and severed from a continuous strip, placed in a die with a conductor and crimped to the conductor. Brass strip 10 is fed intermittently by cams 12 driven by a motor 2 via a one-revolution clutch and gear 30, the motor rotating continuously. The clutch, which is solenoid actuated via a foot switch 7 drives a crank-pin (37) for actuating slides 32, (33), Fig. 2 (not shown). The cams 12 are angularly adjustable and the feed depends on the period of rotation during which the strip 10 is gripped by arcuate cam surfaces 28. The strip, shown in Fig. 5, is positioned with a T- shaped portion of the end terminal 54 over an anvil 23. The slides 32, (33), then descend. A pin 26 on the slide 32 enters a locating hole 53 and a shear blade 52 cuts off the terminal along a line 55. The slide 32 also drives a bending tool assembly 21 downwardly to bend the flanges of the T-shaped portion over the part 51 of the anvil. The speed of the slide 33 now exceeds that of the slide 32 and a ram 43 is driven downwardly. When it contacts the terminal, cam faces (46), 47, Fig. 3 (not shown), move the anvil out of the path of the ram, which drives the terminal into a crimping die 17, where it is secured to one or two leads previously located therein. As the assembly 21 approaches the die, a boss 36 on the slide 32 engages the bottom end of a slot 35 in a slide 31. This slide drives a punch 19a, which pierces another opening 53, punches 19b, 19c, which remove material about the eyelet circumference, and a punch 19d, which removes a bridge 57. On the upward stroke of the slides 32, 33, a spring 24 returns the anvil 23 as the cam faces (46), 47 separate and the boss 36 raises the slide 31 when it reaches the upper end of the slot 35. A stripper plate 15 prevents the strip moving upwardly with the tools.

Abstract: 1280634 Pneumatic floatation conveyers UNITED KINGDOM ATOMIC ENERGY AUTHORITY 28 Oct 1969 [1 Nov 1968] 52017/68 Addition to 1237861 Heading B8A [Also in Division F2] In a conveyer as described in the parent Specification, support means are provided to hold the valve members 5 in their sealing positions when there is a low pressure in the fluid chambers, the support means being inoperative when the pressure is at the operating pressure. As illustrated the valve member 5 is supported by a member 7 mounted on a flexible diaphragm 6. On pressurization of the conveyer, as the pressure in the chamber 2 passes through a predetermined pressure, the diaphragm is deflected, thereby moving the member 7 out of contact with the valve member 5. When the operating pressure is reached, the valve member 5 is held in its seat by fluid pressure until it is dislodged by an article on the conveyer, so as to supply fluid to support the article. After the article has passed over the orifice, the valve member is returned to its seat by being entrained in an unrestricted flow of fluid. When the fluid pressure supply to the conveyer is cut off, as the pressure falls below the predetermined pressure, the diaphragm deflects causing the support member 7 to hold the ball against the valve seat, thereby sealing the conveyer.

Abstract: 530,727. Fatty oils. RAMSEY, A R. J. (Vegetable Oil Products Co., Inc.). May 18, 1939, No. 14869. [Class 91] Partially polymerized fatty oils are separated into a non-drying fraction and a fraction of enhanced drying power by mixing with at least 1 vol. of methyl " Cellosolve " R.T.M. acetate, a ketone, or a higher alcohol ; the drying fraction may be further fractioned by similar treatment. The process is preferably countercurrent. Oils treated include vegetable, animal, or marine oils, e.g. alkali-refined bleached winterized sardine oil, hemp seed oil, linseed oil, cottonseed oil, soya bean oil, partially polymerized by heating in vacuo, e.g. soya bean oil to 550-610‹F. Solvents specified are: acetone, diethyl-, and methylethyl ketones ; diacetone; butyl-, amyl-, hexyl-, tetrahydro-furfuryl alcohols, primary, secondary, or tertiary ; ethylene-, propylene-, and triethyleneglycols; ester alcohols, e.g. ethyl lactate; and ether alcohols, e.g. ethyl " Cellosolve." Conveniently, partially polymerized sardine oil is fed to the top of a tower 6 from a tank by a pipe 3, proportioning pump 4, and a pipe 5, and about 2¢ vol. of acetone to the bottom of the tower from a tank 8 by pipes 9, 10, 11 and the pump 4. A solution of non-drying constituents is discharged through a pipe 12 to a still 13 ; the acetone passes by a pipe 16 to a condenser 17 and is returned to store by pipes 18, 19 ; the saturated glycerides fall through a pipe 14 to a store 15; they may be deodorized, neutralized, hydrogenated, or otherwise treated, and used as salad oils or to make soap. The more unsaturated glycerides are discharged from the tower 6 with some acetone through a pipe 20, a proportioning pump 21, and a pipe 22 to a second tower 26, to which additional acetone is supplied through a pipe 24. The solution of lesser unsaturateds flows through a pipe 27 to a still 28, acetone passing by a pipe 29 to a condenser 17<SP>1</SP> and being returned to store by pipes 30, 19, while the unsaturateds forming a drying oil flow through a pipe 31 to a store 32. The heavy polymerized constituents and some acetone are taken from the tower 26 by a pipe 33, a pump 34, a pipe 35 to a still 36 ; acetone passes off through a pipe 37 to a condenser 17<SP>2</SP> and is returned to store by pipes 38, 19; the oil of enhanced drying power is discharged through a pipe 39 to a store 40. The tower 6 is maintained at 75-100‹F., e.g. 90‹F., the tower 26 at a higher temperature, e.g. 130‹F., but below the B.P. of the solvent. The initial oil, especially when heavily polymerized, may be fed from the tank 2 as a solution in part of the solvent used. In a modified apparatus the tower 6 is operated at a higher temperture, e.g. 110-130‹F., and the solution discharged through pipe 12 is passed through a cooler into a column in which the heavier of these glycerides are separated by cooling and removed from the bottom; the most polymerized glycerides are discharged direct from the base of the tower 6 to a still.

Abstract: 1,168,275. Springs. H. D. GORDON. 30 Nov., 1966, No. 53695/66. Heading F2S. A volute spring unit, formed of a continuous, uniformly wide, ribbon of resilient material, e.g. steel or plastics, coiled upon itself approximately in the form of a general frustum of a hollow cone and used e.g. as a guard to protect machine parts, has one, or both, end turns of the coiled ribbon formed substantially into a cylinder with the substantially circular. edges of each end turn located in planes substantially normal to the longitudinal axis of the cylinder successive helical turns of the ribbon being in overlapping relationship. In this way end turn distortion, or bulging, is stated to be avoided. As shown in Fig. 1 one end turn 21 is cylindrical the spring being fully extended so that the turns, whose sides form progressively greater angles with the axis of the spring from top to bottom, frictionally engage each other. The spring has a substantially constant rate over the greater part, and stiffens appreciably at the beginning and end, of its characteristic. In a modification. Fig. 6 (not shown), some part of each turn, which diverges upwardly, lies on a straight line instead of on an irregular curve as shown in Fig. 1 and each turn is cylindrical, the characteristic of the spring being linear except for the end portions. In a further modification, Fig. 11 (not shown), in which the characteristic on compression differs from that on expansion, both end turns are cylindrical the intermediate turns, which converge upwardly, frictionally engaging to increase the resistance to compression when they have to be forced into parallel relationship. A substantial initial force is required to unlock the collapsed ribbon the characteristic then rising sharply and subsequently falling away rapidly the whole characteristic being in the form of a hump.
