Title: Semi-conductor alloys
IPC: C30B13/08
Filed: 1955-05-12
Abstract: <PICT:0797950/III/1> <PICT:0797950/III/2> <PICT:0797950/III/3> A method of making a monocrystalline alloy ingot comprises melting at least a portion of a mass of semi-conductor material to provide a major constituent of the alloy, and continuously and progressively growing a monocrystalline ingot from the melt while adding thereto a minor constituent of the alloy other than or in addition to a conductivity determining impurity, the minor constituent being added in an amount which increases its content in the melt gradually and progressively or by small increments, whereby an ingot is grown having a minor constituent content which increases along at least a portion of the length of the ingot until an ingot portion having not less than one mol. per cent of the minor constituent is obtained.  In Example (1) a rod-shaped piece of material 2 (see Fig. 4) such as germanium, is placed in a crucible boat 6 with a purified seed crystal 4. Depressions 8 are cut in the surface of the charge 2, and predetermined quantities of an alloying agent 10 placed therein. The crucible 6 is placed in a tube 11 and gradually propelled through a ring-shaped induction heater 12.  The material adjacent to the seed crystal 4 melts first and recrystallizes on the seed crystal 4, successive segments of the charge 2 then being melted and recrystallized.  Larger and larger amounts of the alloying agent are incorporated in the growing crystal.  In Example (2) a tapered bar 21 (Fig. 3) of germanium is placed in the crucible 6 over a bar 11 of silicon with a wedgeshaped end 16, and zone melted as in Example (1), a single crystal growing on a seed crystal 4.  In Example (3) silicon 20 (Fig. 5) is melted in a crucible 18, and a seed crystal 22 is touched on to the surface of the melt and slowly withdrawn so that a single crystal 23 is grown.  As the seed crystal 22 is withdrawn a rod 26 of germanium is gradually fed to the melt 20.  The crystal 23 which is grown is initially pure silicon with the concentration of germanium gradually increasing along its length until a desired composition is reached and maintained by a feed of fresh material to the melt. Tin, lead or titanium may be substituted for germanium or silicon in the examples, and cadmium telluride and gallium antimonide may be alloyed with agents such as germanium and silicon.

Patent GB-792791-A (GB)
Title: A process of preparing substituted amides and intermediates therefor
IPC: C07C233/00
Filed: 1956-05-04
Abstract: Compounds of the formula <FORM:0792791/IV (b)/1> (wherein the benzene nucleus may be substituted by alkyl groups, X is a bivalent aliphatic hydrocarbon radical and Hlg is a halogen atom) are prepared by heating a monohalogenated fatty acid Hlg.X.COOH with an anilide of the formula <FORM:0792791/IV (b)/2> where Z is a monovalent hydrocarbon radical.  This process may be combined with the further step of replacing the halogen atom in the product by a mono- or di-substituted amino group, by reaction with a primary or secondary amine.  The first process is advantageously conducted at 150 DEG  to 200 DEG  C., preferably while passing a stream of dry hydrogen chloride gas through the reaction mixture.  In examples: (1) acetyl-xylidine-2:6 and monochloroacetic acid are heated together and the reaction product is taken up in benzene and heated with diethylamine to give diethylaminoacetyl-xylidine-2:6, identified as the bioxalate and the picrate; (2) butyryl-xylidine-2:6 replaces the acetylxylidine of (1), the final product being identical with the bioxalate of (1); (3) aceto-o-toluidide replaces the acetyl-xylidine of (1), the final product being diethylaminoaceto-o-toluidide bioxalate; (4) the process of (1) is repeated except that dry HCl is passed through the reaction mixture, the yield thereby being increased.  Reference is also made to the reaction of N-butyryl-xylidine-2:6 with alpha-chloro-iso-butyric acid to give N-(chloro-iso-butyryl)-xylidine - 2:6.  Specifications 634,072 and 634,073 are referred to.

Title: Improvements in and relating to electrical remote control systems
IPC: H02J13/00
Filed: 1943-09-04
Abstract: 568,952. Signalling over power circuits. PRICE, D. R., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 4, 1943, No. 14472. [Class 40 (i)] [Also in Group XXXVII] In a system for controlling switching operations over a power circuit in which each receiver is arranged to respond to a characteristic number of impulses of current of a control frequency, which is high compared with the supply frequency, the moving member of the receiver is controlled by a shaded-pole induction motor. As shown, the control frequency operates a tuned relay 4 of the kind described in Specification 517,971, [Group XXXVII], which is coupled to the power circuit by a transformer 7, and may be protected against surges by means of a metal filament lamp 5 and a resistance 11 having a negative voltage characteristic and by the provision of an opposing winding 12, as described in Specification 543,794, [Group XXXVII]. The stator 15 of the induction motor carries an energizing winding 16 connected to the supply, and its poles are provided with shading rings 17 and also with winding 18 connected in series with a winding 19 and normally closed contacts 3 of the relay 4. In the absence of control current, the windings 18 are energized by induction between the windings 16, 19 and the motor tends to drive its shaft and a gear-wheel 32, Fig. 2, in the direction of the arrow, so that a pin 34 on the gear-wheel normally presses against a lever 54 thereby withdrawing a detent 50 from a ratchet 38. The latter is, therefore, urged by a spring 49 into an initial position with a pin 55 against a back-stop 56. When the relay 4 is operated by a control impulse, however, the shading rings 17 become effective to drive the gear-wheel 32 in the reverse direction, and the pin 34 disengages the lever 54 and eventually moves an arm 36 from a fixed stop 43 until it strikes a second fixed stop 44. During this movement of the arm 36, a pawl 47 pivoted thereon slides over a finger 48 and advances the ratchet 38, which is now held against backward rotation by the detent 50. At the end of the impulse the gear-wheel 32 again moves in the direction of the arrow, but the interval between impulses is insufficient for the pin 34 to reach its initial position against the lever 54. The ratchet 38 is, therefore, advanced one step for each impulse until an arm 39 integral therewith closes a pair of contacts 21, which make a circuit for a thermal relay 22. At the end of the series of impulses, the gear-wheel 32 returns to its initial position and the ratchet is released. The final impulse is prolonged sufficiently to allow the thermal relay 22 to operate. Specifications 522,419, 523,360, [Group XXXVII], 535,634 and 536,284 also are referred to.
