Patent GB-343285-A (GB)
Title: Process for the manufacture of carrier bodies for catalytic agents
IPC: B01J23/22
Filed: 1930-01-22
Abstract: A catalyst carrier consisting mainly of silicic acid or strongly acid silicates is obtained by heating materials having a high silicic acid content, such as kieselguhr or precipitated silicic acid, but excluding base-exchange bodies such as zeolites, with silicate-forming metallic oxides or salts, the basic constituent being then removed by extraction.  The temperature of reaction depends upon the material used, and the necessity for completeness of the extraction process.  According to an example, kieselguhr, which may contain 10-15 per cent of alumina and iron oxides, is heated with 6-10 per cent of aluminium oxide.  The aluminium oxide is preferably the precipitate obtained by treating an aluminium salt solution with ammonia, and includes the ammonium salt formed, which loosens the mass in the subsequent heating.  The mass may be moulded, dried at 600-800 DEG  C., but not above 850 DEG  C., and treated with hydrochloric or sulphuric acids to remove the sesquioxide.  The carriers are suitable for reactions in an acid medium e.g. sulphuric acid manufacture.  They may be impregnated with alkali vanadate solutions, or platinized by the process described in Specification 265,938, [Class 1 (i), Chemical processes &c.].

Filed: 1943-02-11
Abstract: 566,067. Electron oscillators. FLOWERDALE, Ltd., PERELMANN, A., and YOUNG, L. Feb. 11, 1943, No. 2311. [Class 39 (i)] Apparatus for the generation, amplification or frequency changing of. high .frequency oscillations comprises a cathode 20, Fig. 1, Wehnelt cylinder 21 and accelerating electrode 22 for producing a stream of cathode rays which impinges on a secondary electron emitting target anode 35 ; the secondary stream oscillates between the anode and a cylinder 38 by means of a grid 36 held at a potential positive relatively to both. The oscillations induce a cyclically varying potential in an electrode 37 which is fed back through a tuned circuit 39 to a control grid 34 in the path of the primary cathode-ray stream. Alternatively, the potential variations of the electrode 37 may be used to deflect the primary stream on and off the target electrode. In a modification, the oscillations take place in a magnetic field parallel to the direction of the primary stream. Another form of the invention is shown in Fig. 3 and comprises two hollow resonators 41, 45 coupled at 46. The primary stream from the cathode 20, Wehmet cylinder 21 and accelerator electrode 22, is modulated by passing through the first resonator, and impinges on a secondary electron emitting anode 25. The secondary stream passes through the second resonator to a collector 26.

Drilling-machines. - A pneumatic rotary engine of the rotary vane type is coupled directly or by gearing to a rotary tool such as a drill and is provided with a distributing valve entirely within the inner element of the engine. Packing washers of varying thickness may be used to adjust the degree of admission through the valve ports. An outer stationary casing a, Fig. 2, carries abutments i, Fig. 1, which co-operate with rotary vanes f carried by an inner rotary member c, recesses g in the vanes allowing them to pass the abutment. Motive fluid is admitted by a pipe b to the interior of a distributing valve m whence it passes through ports k and passages j to the working spaces d. The exhaust passes through ports o and passages p to the outlet r. The vanes f are rotated by aear-wheels t meehing with a toothed ring u carried by the outer casing- Handles y are provided for manipulating the arrangement. A drill &.c. may be attached to an extension t'. In a modification, the outer member carrying the abutments rotates and the innermember carrying the rotary vanes is fixed. In this form one of the hollow handles is used as an inlet pipe and a shield is provided to direct the exhaust away from the operator. In a further modification, the exhaust ports are formed in the abutments themselves. In the construction shown in Fig. 7, the valve is arranged to allow the direction of rotation to be reversed. The valve ports h<1>, j<1> are formed in a member n which is moved by the pressure of the motive fluid to reverse the direction of the fluid through passages g<1>, j according as fluid is admitted above or below the member by the interchange of the inlet and outlet connections b, p<1> by movement of a handwheel k<1>. If the positions of the inlet and outletare reversed in Fig. 7, the member n moving downwards will connect the upper port h<1> with the passage g<1> and the lower port j<1> with the passage j.

Title: Voltage regulator with high voltage protection
IPC: H04N3/18
Filed: 1975-01-22
Abstract: 1486134 EHT supplies for TV apparatus RCA CORPORATION 22 Jan 1975 [31 Jan 1974] 2804/75 Heading H2F [Also in Division H4] The occurrence of a fault in the boost voltage regulator in the horizontal deflection circuit of a cathode-ray tube is arranged to cause a circuit breaker in the A.C. main input power supply to open so that the disabling of the horizontal deflection in addition to disrupting the display also, by disabling the fly-back produced EHT, prevents the emission of harmful X-rays through the tube screen. Fig. 1 shows a known retrace driven horizontal deflection circuit including a known boost voltage regulator circuit supplied with operating voltage via the cathode-gate junction of a silicon controlled rectifier (SCR) 30 and a Zener diode 31 conducting in the forward direction, the boost voltage regulator circuit operating to control the duration of conduction of SCR 34 (which supplies boost voltage to a storage capacitor 32) in accordance with variation in the input operating voltage so as to maintain the voltage at terminal V 0  at a predetermined value. Under fault conditions of the regulator circuit the boost voltage would rise to an unacceptably high value and to prevent this the Zener diode 31 is selected to have a breakdown voltage slightly higher than the highest normal boost voltage so that under fault condition it breaks down in the reverse direction. When this occurs the high voltage is applied to the gate of SCR 30 which then conducts and clamps terminal V 0  to the voltage produced by filter 29. Additionally, the conduction of SCR 30 effectively short circuits winding 27b inductance 33, SCR 34 and capacitor 32. The short circuiting of winding 27b effectively reduces the inductance of winding 27a so that a low impedance path for the operating current exists through winding 27a and commutating SCR 12 to ground which causes the circuit breaker 9 to open and disable the operation of the circuit.

With the magnet positioned as shown core 12 is saturated and pulses of opposite polarity are produced through core 14 in the sense winding outputs SENSE 1 and SENSE 2. Similarly with the magnet moved to core 14 only core 12 produces output pulses of opposite polarity, but in this case the output polarities are reversed. The SENSE 1 and SENSE 2 outputs may be applied to respective input terminals of a bi-stable circuit, Fig. 3 (not shown) triggered by polarity reversal.

Title: Improvements in Governors and other Devices of which the Operation is Dependent upon the Speed of Rotation of a Member.
IPC: H02P5/74
Filed: 1918-02-19
Abstract: 123,381. Cleaver, R. L., and Sandycroft, Ltd. Feb 19, 1918. Electric governors.-A speed governor or regulating-device comprises an alternating-current dynamo-electric machine, the rotor of which is driven at a speed proportional to that of the member to be controlled, and the other part or stator is mounted to turn about the rotor under the opposed influences of the electro-magnetic torque and a restraining torque due to a weight, spring, brake, or the inertia of the part itself. The dynamo-electric machine is designed to give a torque-speed or torque-slip cha.racteristic with pronounced changes of torque at a particular speed or speeds, and operates a control device when the torque attains a particular value or direction in the neighbourhood of those speeds. The machine may be of the induction-motor type, one or both elements being supplied with single-phase or polyphase current, the control taking place near synchronism; or it may be of the synchronous type, one element being excited by alternating current, while the other is excited by continuous current or carries a permanent magnet. The induction machine may have a squirrel-cage rotor with high self-induction. The regulators are specially applicable for use in the automatic control of variable-speed induction motors. Fig. 2 shows the application of the invention to the control of a synchronizing switch for a machine of the kind described in Specification 24837/14; this machine a is started as an induction motor from three-phase leads b with connexions for one of its basic pole numbers, and runs as a synchronous machine at a cascade speed when continuous current is supplied by leads c, d through a switch c. The leads g from the slip rings f are controlled by the switch e; the regulator h receives current from the leads g. The rotor of the regulator is driven from the machine a through gearing k, Figs. 2 and 3. The stator part is free to turn within limits determined by a stop l and. a block n between which a weighted projection m on the stator works. When the torque between the stator and rotor reaches its peak value, the projection m comes against stop l, and contacts p, q come together, closing the circuit of a relay o to operate the switch c to close the circuit of the machine a for synchronous running; the regulator may control the switch e directly. The regulator may itself be a variable-pole machine.
