Title: Improvements relating to atmospheric burners
IPC: F23D14/00
Filed: 1920-12-20
Abstract: 176,546. Weyman, J. E. Dec. 20, 1920. Gaseous-fuel furnaces.-In a furnace for burning blast-furnace, coke-oven, producer, and like gases, the air-supply regulator is separate from the atmospheric burner and is controlled by a governor operated by the gas pressure but arranged outside the passage of gas to the burner. In one form, the internal and external air supplies pass through a bent tube C, Fig. 2, divided by a partition K to annular chambers M<1>, M<2> surrounding the combustion chamber and thence respectively through a box casting N and a port R to the mixing-chamber O of the burner and to the combustion chamber Q. The entrance to the bent tube C is fitted with a hit-and-miss disc regulator J" connected to a gas-actuated governor as described in Specification 122,890, [Class 75 (i), Burners &c.]. The proportion of the external air supply to the internal air supply is regulated by means of an auxiliary hit-and-miss regulator controlling the external air supply apertures in the main regulator and secured in position by a bolt engaging a slot. In a modification in which the air supply is heated by the waste flue gases or by a heater separate from the combustion chamber, the air supply is admitted to the bent tube C through an elbow tube C', and the main air-regulating disc Y and the auxiliary regulating-disc Y<1> are carried respectively by a spindle S and a sleeve T thereon, a quadrant on the sleeve T being adjustably connected to the operating-arm X on the spindle by a thumb-screw and a slot. The air-regulating discs may be mounted on ball bearings. Separate regulators may be employed for the internal and external air supplies. The tube C may be rectangular with shutters instead of rotary discs. Specification 136,774 also is referred to.

Title: Locking device on hydraulic brakes to prevent theft of automobiles
IPC: B60R25/042
Filed: 1960-10-18
Abstract: 897,622. Vehicles, preventing theft. DUNCAN, D. S. Oct. 18, 1960 [Oct. 20, 1959], No. 35704/60. Class 79(3). [Also in Group XXXIV] A brake lock device in a hydraulic brake control system of a vehicle for locking the hydraulic brakes of the vehicle in the applied position to prevent its unauthorised movement, comprises a valve 8 which in the locked position shown closes passages 7 between a chamber I connected by a pipe 10 to a master cylinder and a chamber 2 connected by a pipe 11 of different diameter (to make it difficult to fit an elbow between the pipes 10 and 11) connected to the brake cylinders. A spring 13 acting between a flange 12 on the end of a valve stem 9 and a ported valve seat 5 biases the valve to its closed position, while a stiffer spring 14 acting between the flange 12 and an externally threaded sleeve 16 tends to open the valve. Rotation of a key 27 turns the threaded sleeve 16 from the locked position shown and raises it to compress the spring 14, so that the valve 8 is lifted clear of the ported valve seat 5 against the bias of the spring 13, to allow normal operation of the brakes. In the position shown a brake application will cause the valve to be lifted due to the hydraulic pressure in the chamber 1, but once the pressure in the two chambers has equalized the valve is closed by the spring 13 and the brakes held applied. A bleed may be incorporated to release the brake pressure slowly. The threaded sleeve 16 has passages 22 to equalize the pressure at its two ends, a sealing ring 20a preventing escape of the brake fluid. In another embodiment, Fig. 2, the valve is lifted by means of an eccentric rod 42 held between two rotatable studs 40 and 41, the rod acting on a tappet 46. If the lock is removed a spring 52 pushes the studs 40, 41 to the right thereby breaking a seal 43 and causing escape of the brake fluid. The springs 13, 14, Fig. 1, may be formed from a single spring joined to the flange 12 and to a yoke connected to a tappet which slides in the stem 9. In alternative forms, a spring may be situated between the head of valve 8 and the member 5, the valve may be of resilient material and be of frustoconical shape or of a ball valve kind, and in place of the seal 30, Fig. 1, gasket compounds may be used. The lock can be associated with the ignition control switch of a vehicle.

Abstract: 1,198,696. Semi-conductor devices. RCA CORPORATION. 9 Aug., 1967 [1 Dec., 1966], No. 36604/67. Heading H1K. A method of manufacturing semi-conductor devices includes the steps of providing on a semi-conductor surface an insulating coating 18 having a relatively thick portion and a thinner portion, simultaneously etching an opening 23 through the thinner portion and a recess 25 partly through the thicker portion, re-covering the exposed surface in the opening 23 with a new insulating coating 26, simultaneously etching through the insulation to expose the semiconductor surface beneath the recess 25 and below the thinner portion of the coating 18, and providing electrodes which contact the respective exposed surface portions through the apertures. The embodiment shown comprises a Si planar transistor having an emitter region 24 and a base region 20, 16 diffused into an epitaxial collector layer 14 on an N + substrate 12. The N + layer 12 may alternatively be diffused into the layer 14. The insulation 18 comprises silicon oxide or nitride, and in the former case is applied in two stages, firstly by oxidation of the Si surface and then by decomposition of SiH 4  and O 2 , the total thickness being 14,000 A. The emitter region 24 is diffused in after the initial etching stage which produces the aperture 23 and recesses 25, and the new insulation 26 is then formed by oxidation. The second etching stage exposes part of the base region beneath the recesses 25 and part of the emitter region 24, after which A1 electrodes are vapour deposited on. In this embodiment the aperture 27 is formed through the new insulation 26, but in a second form this aperture is formed through another part (46), Fig. 19 (not shown), of the thinner portion of the main insulating coating (40). The device in this second form of the invention is a multi-emitter transistor. Field effect transistors and integrated circuits are also referred to in the Specification.

Filed: 1970-07-29
Abstract: 1275196 Loudspeaking telephones; automatic gain control STANDARD TELEPHONES & CABLES Ltd 29 July 1970 36704/70 Heading H4R In an automatic gain control circuit, particularly for the receive channel of a loud-speaking telephone, a gate is provided in the gain control channel which is closed during absence of signal in the receive channel so that the gain will not be increased excessively, e.g. when the loudspeaking telephone is being used in the "transmit" mode. As shown, Fig. 2, the receive channel of the loudspeaking telephone has an attenuator on its input, comprising a fet with a control voltage V L  applied to its gate, to control the gain of the receive channel. During normal signal reception the output of the receive channel is fed to a comparator circuit C1 and signals above a predetermined reference level feed through diode D2 to control the impedance of the fet to tend to maintain the output constant. In the transmit mode the switching logic of the loudspeaking telephone applies a negative potential to D1 causing it to conduct so that D2 is cut off, and the fet is driven to saturation, reducing the gain of the receive channel. Since diode D2 is cut off the voltage previously existing on its cathode is held, for a time dependent on the time constant of the capacitors and the leakage resistance in the circuit A2, so that when the circuit switches back to the receive mode the gain is restored substantially to the value it had previous to switching to the transmit mode.
