IPC: F27D3/08
Filed: 1955-01-27
Abstract: 793,613. Tapping rotary kilns. UNIVERSAL ATLAS CEMENT CO. Jan. 27, 1955 [Dec. 2, 1954], No. 2534/55. Class 51 (2). Apparatus for tapping calcium aluminate cement from a continuously operated rotary kiln 10 comprises a plunger 27 adapted to open the kiln taphole 13 at each revolution, a receiver 51 for cooling and granulating molten material M discharged through approximately 120 degrees of the kiln rotation, and an electric control circuit, Fig. 7, whereby the various operations are controlled cyclically. The plunger 27 is operated by a double-acting pneumatic cylinder 21 mounted on a channel member 19 pivotally connected to a yoke 18 suspended from a beam 15, the cylinder 21 being slightly overbalanced by a counterweight 24. Back and front ports 22 and 23 of the cylinder are connected to the exhaust line and to the air supply line respectively of a four-way valve 30 so that the plunger is normally retracted, but when the taphole 13 moves into alignment with the plunger 27 a timing device reverses the valve 30 and operates the plunger. Mounted by brackets 34 on the beam 15 is a shaft 33 to which is fixed a counterweighted trip arm 35 rocked by a lug 32 on the kiln wall. An operating arm 36 fixed to the shaft 33 is connected by a lever 39 to a link 40 and a roller 41 presses the channel member 19 downwards to keep the plunger in alignment with the taphole. The plunger is connected by a rod 44 passing through the piston rod 25 to a microswitch 43 controlling the kiln drive motor, and if the plunger is broken the switch is opened to stop the motor. The receiver 51 comprises a water-cooled conveyer screw 50 driven by a motor 53 and disposed in a trough 54 surrounded by a water jacket 55 formed with spray holes 57 along its length so that the trough may be flooded. Water is supplied to the jacket just before the charge is tapped, and is cut off after the flow from the taphole ceases. The screw 50 discharges into a pit 59, and a splash guard 58 is fitted to the trough. The control circuit, Fig. 7, incorporates a main switch 66 and timer discs 67 and 68 for the tapping device and the water to the receiver respectively connected to the kiln drive and rotating at the same speed. Disc 67 carries an earthed arm 69 which engages a contact 70, energizes a relay A which is connected to the main switch 66 and also energizes a solenoid 71 shifting the valve 30 to operate the plunger 27. The arm 69 only engages the contact 70 momentarily and the valve 30 is then returned to its original position. A directional relay B prevents operation of the plunger if the kiln motor is reversed. The microswitch 43 is connected to a relay C controlling the kiln motor circuit. The timer disc 68 carries a segment 72 which engages a contact 73 to operate the relay D and the solenoid 74 controlling an air valve 74 which actuates the water valve 76 supplying water to the receiver 51. Specification 793,614, [Group XXX], is referred to.

Title: Improvements in or relating to gas analysing apparatus
IPC: G01N7/04
Filed: 1932-01-28
Abstract: <PICT:0385765/III/1> <PICT:0385765/III/2> The invention relates to apparatus of the type in which a measured volume of gas is passed through an absorbent for one constituent and the consequent reduction in pressure is measured.  According to one feature of the invention a pressure - controlled mercury valve 20, Fig. 1, is fitted between the receiver 6 and the pressure gauge 8 to protect the latter from pressure fluctuations except at the end of each cycle of operations. According to another feature, the discharge vessel 14 is in the form of a tube with liquid seal and having an internal core 15 serving to control the pressure range of the apparatus.  The lower end of this core is enlarged and may be adjusted in position in the tube for the purpose of adjusting the zero of the apparatus.  The device shown in Fig. 1 is actuated by an operating liquid continuously admitted at 17.  As the liquid rises it forces the sample of gas contained in the measuring chamber 7 through the absorbent 5 into the receiver 6, while the residual gas of a previous operation is ejected from the measuring chamber 9 through the discharge tube 14.  When the liquid falls again due to the operation of the siphon 16 the receiver 6 discharges its contents into the vessel 9 and is at the same time placed in communication with the pressure gauge 8 by the fall in the level of the mercury seal 20.  A fresh sample is simultaneously drawn into the vessel 7 from the inlet 1. Fig. 2 shows the construction of the mercury valve 20.  A wick 24 is provided for draining condensed moisture from the surface of the mercury into a collecting chamber 25.

Title: Semiconductor read only memories
IPC: G11C17/16
Filed: 1973-01-18
Abstract: 1422045 Read-only memories INTEL CORP 18 Jan 1973 [19 Jan 1972] 2735/73 Heading G4A [Also in Division H1] A read-only memory comprising an array of active circuit elements formed in a monocrystalline silicon substrate of one conductivity type may be programmed by fusing links in circuit with the elements and consisting of a layer of impurity doped polycrystalline silicon between 2800 and 4000Š thick on a 1000Š or thicker silicon oxide layer on the substrate by passing current through them. A 1-3 Á wide neck is provided in each link and a scratchresistant layer of insulation covering the memory is apertured over the necks to keep the fusing current low and to permit connection of the links to conductive members on the layer. In a typical memory the substrate forms the common collector zone of a matrix of bipolar transistors. Each row conductor is constituted by a diffused strip comprising the bases of the transistor in the row, the inter-base resistance being minimized by provision of a heavily doped strip of the opposite conductivity type which is formed in a common diffusion step with the emitters and is conductively connected to the base zones by metallic links. The metal column conductors, overlying oxide or nitride passivation, are connected to the emitters via the fusible links, which may contact the emitters directly or be connected thereto by metallization. As described the polycrystalline silicon is deposited overall and etched via an oxide mask to form the links, prior to heat treating in phosphorous oxychloride to form a glaze on the passivation. The metallization is then done conventionally. In a modification utilizing a matrix of silicon gated IGFETS the fusible links directly contact the sources and/or drains. In this case after forming source and drain diffusion apertures conventionally in thinned portions of an overall oxide layer polycrystalline silicon is deposited overall and etched via oxide masking to form the gates and fusible links, and desired circuit connections. The source and drains regions are then formed by diffusion and the circuit completed by conventional steps.

Filed: 1945-02-14
Abstract: 601,059. Controlling aircraft. UNITED AIRCRAFT CORPORATION. Feb. 14, 1945, No. 3750. Convention date, April 11, 1944. [Class 4] A low aspect-ratio all-wing aeroplane is provided with spring-loaded stabilizing flaps each fitted with a tab or tabs and located on either side of a central elevator in a re-entrant portion of the trailing edge. In one form, Figs. 1-3, the wing 10 is provided with nacelles 18, 20 supporting oppositely-rotating propellers 14, 16, ailerons 26, 28 and an elevator 30 fitted with a trimming tab 36 and pivoted on an axis 32 in a re-entrant portion 34 of the trailing edge. Stabilizing flaps 56, 58 biassed downwardly by springs 66 are pivoted on the axis 32 on either side of the elevator, and each flap carries an outboard upwardly-directed trimming tab 60 and an inboard downwardly-deflected trimming tab 62, the tabs 60 being disposed in the slipstream of the propellers so that a change in engine power is compensated for by movement of the flaps to change the incidence of the aeroplane. The flaps may be connected for simultaneous operation with the elevator by horns 65, Fig. 3, which carry pins 68 engaging slots 70 in links 72 connected to the operating lever 44 of the elevator. The horns may be coupled by a spring 67 to the lever, either of springs 66, 67 or both being used to provide the bias on the flaps. At moderate or high speeds, the pin 68 is in the central portion of the slots 70 and movement of the elevator does not affect the flaps, but at low speeds the pin is moved to the forward end of the slots due to the downward movement of the flaps under the action of the springs, and upward movement of the elevator also moves the flaps upwardly to augment the action. In a second form, Figs. 4 and 5 (not shown), the tabs 60 are omitted and the flaps 56, 58 each have a single downwardly-deflected tab extending the full length thereof. The Specification as open to inspection under Sect. 91 also describes constructions (see Figs. 6-11 (Cancelled), (not shown), in which the flaps are not fitted with tabs and the central elevator and ailerons are replaced by " elevons," or in which the stabilizing surface comprises a single flap which may be locked in a neutral position, or 5 degrees above the neutral position, by spring-pressed bolts actuated by cables under the pilot's control. This subjectmatter does not appear in the Specification as accepted.
