Patent GB-1026489-A (GB)
Title: Semiconductor device fabrication
Inventor: DUNSTER DAVE FRANCIS THOMAS
IPC: H01L29/00
Filed: 1963-11-15
Abstract: 1,026,489. Transistors. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1964 [Nov. 15, 1963], No. 45228/63. Heading H1K. A bi-polar transistor is made by masking one or more areas of a P(N)-type layer on an N(P)-type substrate with insulating material, and diffusing the masked areas with donor (acceptor) impurity to reconvert them to N(P)-type. A region of N(P)-type is subsequently formed in the thus isolated P(N)- region beneath the mask. In a typical example, employing an N-type silicon wafer or an N-type layer epitaxially grown on an Nt wafer as substrate, the P layer is formed by diffusing in boron or by epitaxial deposition. A dot of silicon oxide grown or deposited over part of this layer masks it during a diffusion with phosphorus to isolate the underlying part of the P-type layer. During this diffusion a layer of oxide forms over the entire layer. Phosphorus is next diffused through a window formed in the oxide to form an N-type emitter zone inside the isolated P region which serves as the base zone. Apertures are then etched in the oxide to accommodate metal contacts to the emitter, base, and, if desired, the collector zone.

Abstract: 1449906 Liquid fuel burners OFR OFFICINE FRATELLI RIELLO SpA 3 Oct 1973 [6 Oct 1972] 46208/73 Heading F4T A liquid fuel burner head comprises a fuel atomising nozzle 14 and means coaxial with the nozzle to deliver combustion air around the fuel jet 'from the nozzle, said means comprising a chamber 26 with a primary air outlet 30, and a chamber 38 around the chamber 26 and having a secondary air outlet around the primary outlet 30, the secondary air outlet being adapted to deliver a secondary air flow in the form of a converging generally laminar flow that defines an inner space wherein initial combustion of the primary air/fuel mixture occurs, combustion being completed and the burning mixture diluted by circulating flow induced by the generally laminar secondary air flow outside said inner space. The secondary air outlet is defined by a continuous or interrupted annular gap between a sharp edge 48 of a portion 46 of an outer tubular member 36 and a frusto-conical surface 32, having a cone angle A of 65 to 75 degrees, on an inner tubular member 24 supported on fuel pipe 12. The surface 32 terminates in a sharp edge 34 to ensure detachment of the laminar secondary air flow. The secondary air outlet cross-section may be adjusted by a device 18, 20 acting via fuel pipe 12 to axially move member 24. The primary air outlet 30 is formed in a reduced-thickness part of a diaphragm 28 and comprises a central aperture with slots radiating therefrom and inclined to induce at least part of the primary air to flow in a vortex. Primary air flows into chamber 26 from the outlet 10 of a centrifugal blower via chamber 38 and passages 40, an adjustable nut 42 varying the proportion of primary/secondary air. The communication between chambers 38 and 26 includes a portion, e.g. between the nut and the inlets of passages 40, of smaller crosssection than outlet 30.

Filed: 1969-09-19
Abstract: 1,274,739. Speed governors. SOC: INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE. Sept. 19, 1969 [Sept. 20, 1968; March 25, 1969], No. 46250/69. Heading G3B. Excess smoke during starting of an I. C. engine is prevented by a regulator comprising a centrifugal governor 1 which moves a pump rack 19 via an arm 20 connected to a sleeve 4 moveable axially with respect to a shaft 2 by the governor 1 against the action of an "excess flow spring" 5, "high-speed spring" 13, and an "idling spring" 14, a socket 10 axially moveable on a guide rod 8 and a stop member 32 slideable thereon with a spring 29 disposed therebetween, a lug 39 carried by the sleeve 4, and a lever 30 pivoted at 31 with an end 38 acted upon by the lug 39 and a forked end 36 coacting with the end 37 of the rack 19. In operation, to start the engine, the lever 30 is rotated anti-clockwise to disengage the end 36 from the flanged end 37 of the rack. The rack 19 is set to the maximum flow position by a spring 22. The engine accelerator is depressed to rotate a cam 15 clockwise to compress springs 5, 13 and 14 to the maximum and the engine is started. As the engine picks up speed it moves the rack to reduce the fuel supply until a shoulder 12 on the sleeve 4 contacts a flange 34 on the stop 32. The lever 30 is then released and a spring 40 moves the end 36 into contact with the end 37 and moves the rack until the end 38 contacts the lug 39. With the cam in the high-speed position the engine speed continues to increase. The spring 29 is calibrated to yield when the engine reaches idling speed. Above this speed the sleeve 4 acts to compress the spring 29 without moving the socket 10 until the flange 34 contacts a flange 35. In Figs. 9 to 14 (not shown) a sleeve (4b) contacts a ring (10a) at idling speed when a spring (5a) has been compressed.

Abstract: 962,876. Photo-electric control circuits. T. A. SCANLON. Dec. 14, 1962, No. 47363/62. Heading G1A. The invention relates to apparatus for automatically energizing an electrical circuit such as a parking lamp circuit of an automobile in response to a predetermined drop in ambient lighting, and comprises a source of D.C. voltage, a circuit to be energized connected across the source and including a normally closed electrically controlled switch 18, and means energized by the source for opening the switch 18 including a transistor 16 and a solenoid 17 which operates the said switch, the solenoid 17 and the emitter and collector of the transistor 16 being connected in series across the source, a resistive voltage divider network 13, 14 also connected across the source and a light sensitive resistor such as a cadmium selenide photocell 15 connected between a point 25 on the divider network and the base of the transistor whereby in response to a pre-determined level of ambient light striking the photo-cell 15, the transistor is biased to allow the solenoid to be energized and hold the switch 18 in the open position. In the Figure shown the switch is in series with the parking lamps 19 of an automobile and in response to high ambient light striking the photo-cell 15 its resistance is low thus biasing the transistor to a conducting state and thereby causing the solenoid to hold open the switch 18. When the level of the ambient light falls to a predetermined value the resistance of the photo-cell 15 is such that the transistor 16 ceases to conduct thereby causing the solenoid to be de-energized thus allowing the switch 18 to close and complete the circuit through the lamps 19.
