Title: Improvements in or relating to zinc blast furnace
Inventor: DERHAM LESLIE JACK
IPC: C22B19/04
Filed: 1966-09-01
Abstract: 1,140,591. Extracting zinc. IMPERIAL SMELTING CORP. (N. S. C. ) Ltd. Aug.9, 1967 [Sept.1, 1966], No.39087/66. Heading C7D. The zinc condensing efficiency in a zinc producing blast furnace unit which comprises a feed preparation machine, feed transfer apparatus, furnace charging gear, furnace shaft, gas offtakes and at least one condenser for zinc of the leadsplash type, is improved by introducing free or combined chlorine into the furnace unit. Combined chlorine may be used in the form of hydrogen chloride, ammonium chloride, or the chloride of a Group I or II element. The examples relate to (a) the introduction of chlorine gas into the offtake tube between shaft and condenser, and (b) the charging of sodium chloride briquettes to the shaft.

Title: Improvements relating to the fabrication of semiconductor devices
IPC: H01L21/00
Filed: 1969-08-05
Abstract: 1,262,705. Semi-conductor device manufacture. INTERNATIONAL BUSINESS MACHINES CORP. 5 Aug., 1969 [6 Aug., 1968], No. 39125/69. Heading H1K. The carrier lifetime of a selected region of a semi-conductor body is reduced by the ion implantation in that region of lifetime killing impurity. Gold is specified as a killer impurity. An ion beam energy of greater than 1 KeV may be used and irradiation carried out for 5 to 15 minutes to give an implant concentration of about 10<SP>15</SP> to 10<SP>20</SP> atoms cm.<SP>-3</SP>. The semiconductor body should be kept above 100 C. during implantation to prevent cold-working and below 600 C. to avoid diffusion. The preferred temperature range is 300-500 C.; within this range later annealing is not necessary. By suitably choosing the beam energy, implantation may take place at any depth below the surface while the overlying material remains substantially unaffected. Though in other steps diffusion and epitaxial growth may be used, in illustrative description an integrated structure is produced from a uniformly doped body by a series of ion implantation steps involving the killer impurity and dopants determining the conductivity type. In general suitable semi-conductors are Si, Ge, A<SP>II</SP>B<SP>VI</SP> compounds, and A<SP>III</SP>B<SP>V</SP> compounds such as GaAs. Dopants (other than lifetime killers) which may be introduced by ion implantation are Ge, Si, N, Sb, P, As, B, In, and Ga. To produce a steep significant impurity profile He may be implanted in a region and the significant impurity then implanted in the same region. In the structure shown all the regions are formed by ion implantation. Selective implantation may be achieved by beam focusing and scanning, by inserting a metal mask in the beam, or by the provision of a photoresist or metal masking layer on the semi-conductor body. The N<SP>+</SP> collector subregions are formed first and then the beam energy is progressively reduced to provide uniformly doped collector regions 12, 13, 14. Other regions are provided as shown to provide the three NPN transistors with emitters 32, 34, 38 (two of the transistors being connected by an underpass conductor 40), a PN diode 26, 14, a PNP transistor 52, 42, 10 having a steeply graded base region in the first production stage of which He-doping was used, a resistor structure 56 with electrode regions 44, 46 (the resistor could be made subsurface), a linked composite diode structure 48, 10c, 49, 58, and a capacitor 54.

Filed: 1972-08-24
Abstract: 1441573 Flexible hose ALENCO HILYN Ltd 24 Aug 1973 [24 Aug 1972] 39499/72 Heading F2P In manufacturing a reinforced flexible hose a thermoplastic tube is provided with an external reinforcement of braided or spiral form, the assembly is heated whilst applying a positive pressure difference between the inside and the outside of the tube to cause expansion of the tube against the reinforcement such that the outer surface of the tube is deformed to follow the internal contours of the reinforcement and the assembly is then cooled or allowed to cool whilst maintaining the pressure difference whereby the tube is stressed and permanently set in such state. An outer sheath of thermoplastic material may be formed around the deformed tube by extrusion and this may be done before the cooling operation so that the outer sheath is welded or bonded to the softened thermoplastic material of the tube. Alternatively an adhesive or cement may be used. Preferably the pressure difference is created by applying pressure inside the tube whilst the latter is passed continuously through an oven for a time and at a temperature sufficient to soften or melt the outer surface of the tube. The temperature, pressure and heating time may be adjusted so as to soften the inside of the tube sufficiently to cause the bore to assume a true circular shape. The softening or melting of the outer surface of the tube is said to allow any disconformities or tensions in the reinforcement to be relieved thus enhancing the properties of the hose. If desired two or more layers of reinforcement may be provided such layers being separated by thermoplastic material. The material of the tube may comprise a polyolefin, polyamide, polyvinyl chloride, polyester or polytetrafluoroethylene and the reinforcement may be of a natural or synthetic fibre textile or wire.

Abstract: 1,046,869. Monitoring radio transmitters. MARCONI CO. Ltd. July 3, 1964 [Oct. 8, 1963], No. 39602/63. Heading H4L. In a modulated carrier wave transmitting installation standby equipment is automatically brought into use if either the modulation content or the carrier wave should fail. Two equipments 1, 1A produce identical modulated carrier waves which are supplied via gates 2, 2A to detectors 4, 4A which are appropriate to the type of modulation (amplitude or frequency). The outputs of the detectors are compared at 5, 5A respectively and so long as the modulation contents of both signals are equal both gates 2, 2A are conductive but any failure in equipment 1 or 1A causing a difference in the signals from detectors 4, 4A will cause the corresponding gate 2 or 2A to be blocked. The gates 2, 2A are followed by further gates 3, 3A and carrier detectors 6, 6A which provide a D.C. representative of the carrier passed by the corresponding gates, the output from detector 6 blocking gate 3A if the input to that detector is of correct value while that from detector 6A blocks gate 3 if the input to detector 6A is of the correct value. A selector switch 7 determines which of the gates 3, 3A is rendered conductive in the absence of a fault. The outputs of gates 3, 3A are supplied to a common output circuit 9.

Abstract: 347,583. Plant for making and baking bread &c. HARDER, L. S., POINTON, J. E., and BAKER PERKINS, Ltd., Westwood Works, Peterborough. Dec. 27, 1929, No. 39605. [Class 28 (i).] A dough moulding, proving, and baking plant comprises a moulding machine 6 which receives dough lumps from a series of sources and a selecting device 16 which transfers the moulded dough pieces into different paths appropriate to the subsequent treatment required. Thus, a dough divider 5 may discharge lumps alternating with lumps received from the shoot 13 of a first prover 11, the conveyer 8 transferring these alternately arranged lumps to the flap 16 which is so oscillated that the lumps received via the moulding machine 6 from the divider 5 are transferred to the first prover 11, while the lumps received via the moulding machine from the first prover are transferred to a transversely moving conveyer 14 which carries them to a second or final prover 15. The proved dough is removed from the final prover at 15a which is conveniently near the inlet of a continuous oven 18 whose discharge is preferably at the same end as the inlet. According to a modification, the plant may be arranged on two floors, the oven being on the lower floor, while the divider, moulder and final prover are on the second floor, the first prover being arranged on the ceiling of the lower floor.

Filed: 1971-08-25
Abstract: 1303236 Integrated complementary transistors INTERNATIONAL BUSINESS MACHINES CORP 25 Aug 1971 [3 Sept 1970] 39859/71 Heading H1K A complementary pair of transistors is formed in a silicon layer 7 grown epitaxially on the substrate of Fig. 1. In Fig. 1 the p-type diffused regions 4, 5 are boron-doped and the n-type diffused regions are arsenic-doped. During the manufacture the relatively mobile boron (from region 5) converts the overlying part of the n-type epitaxial layer 7 to p-type to form the collector zone of the second transistor T 2  (Fig. 6). The arsenic in zones 2 and 3 moves relatively little. During early stages of processing the p-type isolation diffusions are made and the base region 8 of the first transistor T 1  and the collector contact region 10 of T 2  are formed. Apertures are then formed in a silicon dioxide masking layer 13 to provide for the formation of the emitter of T 1 , the base 18 of T 2 , and the collector contact region of T 1 . Diffusion is effected from an arsenic-doped silicon dioxide layer 12. Part of this layer is removed and a new apertured masking layer 17 formed to provide for the formation of the emitter 20 of T 2 . This is formed by boron diffusion and the process is accompanied by enhanced diffusion of arsenic into the emitter region and collector contact region of T 1  from the residual parts of the arsenic-doped oxide layer 12. This manufacture ensures that the transistors are matched in spite of the difference in hole and electron mobilities.
