Title: Cathode ray deflection circuits
IPC: H03K4/43
Filed: 1950-12-29
Abstract: 682,834. Impedance networks. RADIO CORPORATION OF AMERICA. Dec. 29, 1950 [Dec. 31, 1949], No. 31597/50. Class 40 (viii). In cathode-ray deflection apparatus having a transmission line 42 connecting a source to a deflecting coil 40, a resistance Re is connected in series with the coil 40, and a capacity C and resistance RT, connected in series, are connected in parallel with the first combination. If the resistance of the coil 40 is represented by rL, and its inductance by L, and the characteristic impedance of the transmission line is equal to RT, which equals rL+Re, which equals L V -, then the line 42 is terminated effectively C in a pure resistance. Resistances RT and Re may be formed by different portions of a single resistor, with a tap to ground interposed between the portions. Saw-tooth current is supplied from generator 12 for the deflection coils. In order to compensate for the distorting effect of resistance Re on winding 40, pulses from generator 14 are combined in the required quantity with the saw-tooth wave, through the adjustment of potentiometers 20 and 22, to produce a wave with a compensating distortion which, after amplification in valve 30, passes through line 42.

Filed: 1928-10-31
Abstract: 325,867. Cumming, M. W. Gordon-, and Automatic Records Player, Ltd. Oct. 31, 1928. Multiple machines.-In a gramophone, or the like adapted automatically to play a number of records in succession, the records 7 are supported in an inclined position above the turntable 21 by stationary supports 8 and a continuously-rotated disc 2 having a cut-away portion 3 adapted to release the records, a plate 4 adapted to enter periodically between the record next to be released and that above it being so mounted on the disc above the portion 3 as to be capable of a slight movement in the direction of the thickness of the records, whereby the plate can adapt itself to varying thicknesses of records. The movement of the plate, towards the upper surface of the disc is limited by pins 6. As shown, the plate is pivoted to the disc, but it may alter. natively be formed of resilient material secured to the disc at a point remote from the portion 3. The shaft 1 to which the disc is secured and which is carried in a fixed tube 14 is rotated by a ratchet wheel 16 driven through a pawl 17 by a lever 18 engaging an eccentric 20 secured to the turntable 21. When a record is released by the movement of the disc, it slides down a rod 10 carried by a pivoted support 11 and depresses an arm 24 secured to the goose-neck 25. whereby the sound box 26 is raised until a pin 29 on the nrm 24 engages the tone-arm 27. The latter is thus swung outwardly until it engages the tube 14. The record now falls on to the turntable, and, due to the weight of the goose-neck, the arm 24 slides along a stationary inclined surface 30 until it engages the inclined edge 23 of a plate 22 depending from the disc 2. The soundbox is now above the starting position on the record and, as the disc continues to rotate, is lowered on to the record.

Title: Improvements in or relating to a method and apparatus for dynamic filtration of slurries
IPC: B01D33/073
Filed: 1964-08-07
Abstract: During filtration of slurries by a filtration diaphragm, the filtration cake is removed from the diaphragm and mixed with the unfiltered slurry, the mixture being kept in liquid state by agitation.  In one embodiment a pressure vessel (1), Fig. 3, (not shown) of lenticular cross-section, has a neck penetrating one side axially and occupied by a hollow shaft on the inner end of which is mounted a hollow filtration body with filter diaphragms on both sides; the other end of the shaft serves as filtrate outlet.  Slurry is fed continuously into the vessel and is intensively agitated by rapid rotation of the filter body; an outlet for mixed slurry and filter cake is controlled by a valve which is kept closed initially until optimum concentration in vessel (1) is achieved.  Thereafter the valve is controlled to maintain this optimum concentration. Filtrate removal from the filter body interior may be effected by a fixed disc with radiating arms communicating with a pipe inside the hollow shaft; the disc may be replaced by two radial pipes.  Three filters may be connected for filtration and two-stage washing.  In Fig. 11 (not shown) a fixed annular hollow disc with a filter membrane on one side only has a rotatable shaft extending through its central hole, the shaft having on its end a disc which is rotated close to the filter surface to effect the required agitation in the pressure vessel.
