Filed: 1959-01-26
Abstract: 886,314. Centrifugal separators. DYNAMIC FILTERS Inc. Jan. 26, 1959. No. 2792/59. Class 23. [Also in Group XXVI] A centrifugal clarifier comprises a rotor 41 having annular chambers 200, 201 for the reception of separated solids. Fuel to be cleaned from a stationary inlet 13 flows through apertures 63 and annular passage 203 into an annular chamber 204 within the rotor. Vanes 61a, . . . 61d are provided in the chamber 204 to rotate the liquid. During passage of the fuel through the chamber 204 solids pass through louvers 85 and are deposited in the chamber 200. The fuel leaves the chamber 204 through ducts 93 and passes into an annular chamber 205. During passage of the fuel through the chamber 205 solids pass through louvers 97 to deposit in the chamber 201. The chambers 200, 201 have vanes 82, 99 which maintain an even distribution of the deposited solids and so prevent unbalance of the rotor. Cleaned fluid is discharged from the chamber 205 and the rotor through holes 101 into the casing 206 which has an outlet (not shown). Different diameter guides 139 may be attached to the rotor to cover the holes 101 so that the pressure difference on the fuel passing through the rotor may be controlled. The clarifier is dismantled for cleaning by removing screws 30, removing part 29 of the casing, sliding the hollow drive member 45 together with the rotor from the drive shaft 15, sliding the stub shaft 39 from the drive member, unscrewing screws 72 to force off part 71 from the rotor, and separating the interior parts of the rotor.

Title: Protective circuits for intermittently operable electrical circuits
IPC: G01S7/282
Filed: 1945-02-05
Abstract: 591,874. Protective devices. PHILCO RADIO & TELEVISION CORPORATION. Feb. 5, 1945, No. 2924. Convention date, Nov. 2, 1943. [Class 40 (v)] A current limiting device for an intermittent load comprises a series resistance and means including capacity shunted across the load to maintain the voltage substantially constant during an operating period. Fig. 3 shows the device applied to a pulse modulated cavity oscillation generator in which the voltage maintaining means comprises an artificial delay line. During the interval between pulses, when the valve is biassed to cut-off capacitors 15, 16, 17 charge through registor 13. Application of a pulse to the valve causes it to conduct so that the anode voltage falls to 22 (Fig. 4) owing to the surge impedance of the line. This causes a voltage pulse to travel along the line to the open circuited end, where it is doubled and reflected back to the anode, causing a further drop in potential to 23. The time constant of the line being one pulse interval in this case. If grid pulse initiates a flashover, the same action occurs but with larger amplitudes, so that the final voltage is below that required to sustain an arc. In a modification (Fig. 2, not shown), a capacitor may be used instead of the delay line. Application to a pulse modulated Hartley oscillation generator is also described.

Patent GB-1496081-A (GB)
Title: Charge coupled devices
IPC: G11C19/28
Filed: 1975-01-24
Abstract: 1496081 Charge-coupled devices HUGHES AIRCRAFT CO 24 Jan 1975 [25 Jan 1974] 3205/75 Heading H1K Means for injecting charge into a CCD while avoiding firstly the coupling back of voltage spikes from the clocked transfer electrodes into the injecting junction and secondly deleterious charge accumulation and bias voltage build up at the injecting junction during the OFF clock period on the first transfer electrode comprises an electrode structure 41 (Fig. 2) between the injecting junction 19 and the first clocked electrode 17, the electrode structure having applied thereto a steady bias voltage which induces a potential wall in the underlying semi-conductor 13. The wall serves as a reservoir of charge during the OFF clock period of the first clocked electrode 17, and isolates the injecting junction 19 against the coupling back of voltage spikes. The electrode structure 41 comprises a transfer portion 43 adjacent the injecting junction 19 and a storage portion 45 adjacent the first clocked electrode 17, the fixed potential well being deeper under the storage portion 45 than under the transfer portion 43. In the 2-phase arrangement of Fig. 2, in which each clocked electrode consists of electrically connected transfer portion 17a and storage portion 17b respectively on and embedded in SiO 2  layer 15, the two portions 43, 45 of the electrode structure 41 are similarly arranged. An output arrangement including two MOS transistors, only one of which is shown in Fig. 2 (51), is described in detail. The type of construction shown in Fig. 2 is applicable to an infra-red imaging array ineluding a plurality of InSb i-r detectors each of which feeds charge laterally into a corresponding stage of a CCD shift register via a fixed-voltage electrode structure such as 41. Each CCD stage consists of four pairs of clocked transfer and storage electrodes. The clocked transfer and storage electrodes which, in each CCD stage, are located nearest to the charge input arrangement from the detector are specially shaped to facilitate passage of injected charge into the main CCD stream (see Fig. 8, not shown). The clock frequency is synchronized to the rate at which an i-r image is stepped across the detectors, so that all the charges from an element of the image arrive at the final CCD stage simultaneously. Since this means that the charge temporarily accommodated in each successive CCD stage is larger than in its predecessor the channel width, as defined by highly-doped chargestopping strips running alongside opposed edges of the channel, is increased step-wise at each successive stage. Fig. 11 shows the application of the invention to a 3-phase shift register. Here all the electrodes lie in a common metallization level and the transfer and storage portions 145, 147 of the input electrode structure are electrically independent, being connected to different fixed voltages so that a deeper potential well is induced beneath the storage portion 147 than beneath the transfer portion 145.
