A thicker layer of the electrode metal is deposited over the thin reducing metal layer, followed in sequence by at least one layer of a dopant and another layer of the electrode metal, and the multi-layer structure is then heated to form a melt of the electrode metal, the dopant and the semi-conductor, from which melt the dopant diffuses into the semi-conductor body. For contact to P- and N- type Si the reducing metal may be Ti, Nb or Zr, the electrode metal may be Ag, Au or Sn and the dopant may be Al or Sb. Transistors and diodes are mentioned, but the main embodiments are contacts for varicaps. In one example, separate layers of Al and Sb alternate with Ag layers in the preliminary structure and diffuse together into the P-type Si body on heating to form the required PN junction. The electrode and dopant layers may be vacuum deposited or, if a layer of Ni is provided immediately on the layer of reducing metal, may be chemically or electrochemically deposited.

Title: Crystalline chlorinated polypropylene
Inventor: ROBINSON IVAN MAXWELL
IPC: C08F8/20
Filed: 1964-08-12
Abstract: A crystalline chlorinated polypropylene having an X-ray crystallinity of at least 50% and a chlorine content of at least 5% is prepared by chlorinating a polypropylene having an X-ray crystallinity of at least 50%.  The chlorination is preferably carried out in an inert liquid organic medium such as carbon tetrachloride and the polymer is preferably suspended in part, and dissolved in part, during the initial stages of the chlorination, the final chlorination generally being carried out in a homogeneous liquid phase.  Alternately, the polypropylene may be chlorinated under actinic light in a chlorine atmosphere.  The polypropylene to be chlorinated may be obtained by polymerizing in cyclohexane using a catalyst comprising TiCl4 + LiAl(ethylcyclohexenyl)4 in xylene to give a polypropylene having a density from 0.87 to 0.89 and a crystallinity of 24%.  By extraction procedures polypropylenes of the desired crystallinity can be obtained.  The polypropylene may be preformed into a shaped structure and then chlorinated.  Stabilizers may be added to the chlorinated polypropylenes to prevent degradation.

Abstract: 1504422 Production of formcoke CARL STILL 8 Aug 1975 [14 Aug 1974] 33166/75 Heading C5E [Also in Division F4] A process for the production of shaped coke comprises mixing caking fine coals with fine coke, pressing the mixture into briquettes in the plastic temperature ranges of the coals, the briquettes then being hardened, degassed and coated; the fine coke is produced by coking a non-compressed stream of particulate coal in a shaft furnace by radiant heat. In the apparatus shown, pulverized coal is conveyed from bunker 1 to shaft furnace 10 by hot combustion gases from burner 2, the fine coke thus produced being mixed in mixer 12 with bituminous caking coal from bunker 13 and briquetted in roller press 23; the briquettes are then hardened in tank 26 at 450-750‹ C. and cooled in bunker 29. Hot coke oven gases from the shaft furnace 10 pass through outlets 34 and are conveyed via line 37 to the hardening tank 26 where they heat the briquettes; the coke oven gases then pass through heat exchanger 39 where they are used to generate steam, and from there to a purifying plant. The steam generated in 39 is fed through pipes 53 to the outlets 34 where it reacts with the coke oven gases using heat provided by flues 35. The Figure also shows the heating flues 32 and regenerators 33 of the shaft furnace 10. Figs. 3-5 (not shown) give in detail the construction of the heating system of the furnace 10. The dimensions of the furnace and the angle of inclination of the gas outlets is specified.

The shaft 6 has a shoulder 15 within the extension 11 and a shoulder 16 within a recess 17 in the control knob 10, a -spring 18 acting between the shoulder 16 and the sleeve 9. A cross-pin 19 on the outer end of the shaft 6 can be engaged in slots 20 in the knob 10 at the bottom of the recess 17. When the knob is pushed inwardly the sleeve 9 engages the shoulder 15 and thus causes the shaft 6 to move axially and engage the pin 12 in the slots 13, the sleeve being held by a ball 24 urged into a groove 23 by a spring 25. When the knob is pulled outwardly so that a groove 22 on the sleeve engages the ball 24, the pin 12 is removed from the slots 13 and the spring 18 compressed. On further outward movement of the knob the recesses 20 engage the pin 19 so that the shaft can be rotated manually. The knob when released is returned by the spring 18 to a position in which both clutches 12, 13 and 19, 20 are disengaged. In a modification described with reference to Fig. 2 (not shown), only two operating positions of the knob are provided, one in which the shaft pin 12 is engaged in the slots 13 of the hub 14 or one in which the pin 12 engages in slots in the end of the sleeve. The sleeve is in two parts slidably coupled together, the inner part having the slots and also restrained from axial movement, but capable of limited rotation.
