Title: Circuit board pins
IPC: H01R12/58
Filed: 1975-10-09
Abstract: 1502864 Circuit board pins E I DU PONT DE NEMOURS CO 9 Oct 1975 [10 Oct 1974] 41494/75 Heading H2E A circuit board pin comprises a mounting portion having three fins that extend lengthwise of the pin. At least one of the pins, in transverse cross-section has an axis that extends to the central longitudinal axis of the pin, the outermost surfaces of the fins being spaced apart. As described, the pin is square or round in cross-section, one of the fins, fin 28 in Fig. 4, being radially extending. The remaining two are preferably laterally offset from the central longitudinal axis 34 and may be parallel as shown, may flare to diverge, (Fig. 8, not shown), or may each incorporate a twist (54) (Fig. 14, not shown). In the latter two cases, the rounded hole engaging surfaces of the fins are equally spaced. Various hole sizes are accommodated by resilient flexing of the fins. This is effected, as shown by shearing the fins 28, 30. Alternatively, Fig. 9, not shown, the radial fin (168) may be rigid whilst the remaining parallel or flared fins (70) are connected thereto and may resiliently flex toward one another. In the case of an outsize hole, Fig. 11, not shown, after loose insertion of the pin, a longitudinal compressive force is applied to force the fins outwardly so as to frictionally engage the aperture in the circuit board. Fixing of the pin may be completed by soldering. The pin may have square ends for receiving twisted wire, or a female terminal as shown. Alternatively an end may have an integral female terminal whilst the other has a square male terminal (Fig. 13, not shown). For a square cross-sectioned pin of width X at the ends, the preferred dimensions of the mounting portion are fin transverse width and length about X/3 and X respectively, with the hole engaging surfaces of the fins being greater than X/#2 from the central longitudinal axis of the pin, one fin extending perpendicularly outwardly from one side of the pin the other fins being located on opposite sides of said one fin.

A spring-pressed ball 12 engages locking recesses (not shown) in the earthed metal cover 2 to lock switching element 4 at selected positions of displacement along the axis of trunnions 4a, 4b. Spring-pressed ball 11 is engaged by a shoulder 5a of operating member 5 to provide resistance to the further longitudinal displacement of member 5 when it is pushed to engage contact spring 19 from its initial displaced position engaging contact spring 18. Springs 18, 19, are engagable by member 5 in any displaced position of element 4. Two locking recesses 23, 24, fix the zero position of bridging contact 22 of the potentiometer, element 6 being rotatable in either direction to bring in the highest or lowest resistance immediately. Current supply from terminal 28 to contact 22 is via a circular conductor track 27, a wiper 26 and a spring 25. Current supply through the potentiometer arrangement is only possible when switching element 4 is in the zero position, when a terminal 30 on base plate 1 is contacted by a contact spring 29 of the switching element 6.

Exchange highways EHA are each duplicated i.e. EHDA which is phase displaced by, say, one channel delay. A multiple of this delay but less than one frame in total may however be employed. The phase difference so introduced results in the provision of two possible zero delay interconnecting paths between like channels of two highways.

In a hydrocarbon cracking or other process involving continuous heating of a fluid (which may be liquid, vapour or a mixture thereof), the fluid whilst being heated is continuously streamed through tubular conduits in a residence time of from 0À10 to 0À50 seconds and at a mass velocity of from 15 to 35 1bs./sec./sq. ft. of cross-sectional area, whilst the fluid pressure decreases from about 10 to 30 p.s.i. In the hydrocarbon cracking processes described, in which hydrocarbon feeds (e.g. ethane, propylene, propane, butane, pentane, naphtha, gas oil, crude oil) are thermally cracked to produce olefins (particularly ethylene), the fluids are subjected to an average heat flux of from 20,000/35,000 B.T.U.'s/hr./sq. ft. and are heated to a temperature of 1500/1650‹ F. before being rapidly cooled in from 1 to 30 milliseconds down to a temperature below which substantially no deleterious reaction takes place (e.g. 1000/1400‹ F.). The feed may be preheated to a temperature of 1100-1200‹ F. and diluted with steam during which the feed may be partially or wholly vaporized. A furnace for carrying out the process and a process and apparatus for rapid cooling of the hot fluids is described in Specifications 1,165,905, 1,165,906 and 1,165,908.

Title: Phototropic glass composition and method of treating it
IPC: C03C4/06
Filed: 1963-11-05
Abstract: <PICT:0984652/C1/1> A phototropic glass consists essentially, in per cent by weight, of: SiO2, 48-57; Al2O3, 6-10; B2O3, 15-22; Na2O, 0.8-2.0; Li2O, 2.4-3.1; K2O, 0-4; total Li2O+Na2O+K2O, 3.2-7.2; PbO, 4.5-5.3; BaO, 3-9; ZrO2, 0-7.2; Ag, 0.15-06; CuO, 0.01-0.02; Cl, 0.3-1.2; Br, 0-1.0; I, 0-1.0; F, 0-1.2. Batch materials used may include AgNO3, NaCl, NaNO3, Na2SiF6.  The glass is transparent to visible radiation but transmission thereto of a sample of thickness 2 mm. upon exposure to light of wavelength 3000-4500 <\>rA, is less than 45% of its original value, with a half-fading time, i.e. the time taken for the change from absolute minimum transmission to the geometric mean of the absolute minimum and initial transmissions, of less than 300 sec. The refractive index is 1.52-1.54.  The glass is produced by melting the batch, e.g. at 1400-1500 DEG  C. and forming the molten glass. The glass may be cooled during forming to below its softening point 640-670 DEG  C., and the formed article is then optionally cooled to room temperature with annealing.  The article is then heat-treated by exposure to a temperature of 500-750 DEG  C. to cause precipitation of sub-microscopic crystals of radiation-sensitive material within the glass, thereby imparting phototropicity.  The glass is cooled to room temperature; this cooling may be performed in such a manner that the glass is annealed. For ophthalmic lenses, a 1/4 inch annealed slab of glass not yet heat-treated is cut and ground to 2 mm. thickness.  The lens blanks are then heat-treated according to the schedule of the Figure. Specification 950,906 is referred to.
