Title: Liquid delivery and contaminant extracting device
IPC: B04B11/02
Filed: 1959-01-26
Abstract: 886,384. Centrifugal separators. DYNAMIC FILTERS Inc. Jan. 26, 1959 [March 28, 1958], No. 2793/59. Class 23. [Also in Group XXVI] Liquid, e.g. aircraft fuel, entering at 52 is drawn by a pump impeller 22, consisting of a conical base 107 and a screw type blade 109, into the space between the conical base 107 and a conical housing 50 rotating at a lower speed than the impeller. The liquid emerges at 184 and its direction is reversed by the radial part 119a of a hub 119, the liquid thereafter flowing between the housing 50 and a cylindrical sleeve 133 rotating with it and having openings 135 formed by making cuts in the sleeve and bending up the adjacent metal to form louvres 137. Solids are discharged through the openings 135 and caught in a cylindrical body member 121 also rotating with the sleeve. Liquid is continuously discharged through holes 51 in the end wall 125 of the housing 50. The liquid is received in an outlet passage 55 and finally discharged through an outlet port (not shown). The impeller is keyed to a shaft 37 driven, through an adapter 41, by an aircraft engine for example. The shaft 37 is provided with an integral gear 143 which drives, through an eccentricallymounted idler gear 145, a gear ring 153 fitted to the hub 119, at a speed e.g. two-thirds that of the impeller. The radial part 119a of the hub is secured between the end of the housing 50 (which has several radial vanes 139) and a short flange 121a on the cylindrical body member 121 by bolts 129 which screw into the end wall 125 of the housing 50. The apertured sleeve 133 is located between the shell 50 and body member 121 (which also has several radial vanes 141). Thus hub 119, body 121, sleeve 133 and housing 50 all rotate as a unit. The hub 119 is mounted on bearings 115, 117 on shaft 37 and the housing 50 is a push fit on a tapered member 59 against which a fixed sealing member 63 is pressed by a spring 68. If rotation should cease during use, a by-pass valve 167 opens so as to maintain adequate pressure for any following pump in the fuel line. A further by-pass valve 171 permits flow of liquid from outlet back to inlet should the impeller create too high a pressure. Specification 886,314 is referred to.

Title: Transistor
IPC: H01L27/06
Filed: 1966-01-21
Abstract: 1,088,624. Semi-conductor devices. CENTRE ELECTRONIQUE HORLOGER. Jan. 21, 1966 [Jan. 29, 1965], No. 2851/66. Heading H1K. [Also in Division G3] A planar semi-conductor device comprises a transistor provided with a distributed capacitative-resistive connection between the base and collector regions. As shown, Fig. 1, a P-type base region 2 having an elongated arm 5 is diffused into an N- type silicon wafer 1 which forms the collector, and an N-type emitter region 7 and a further N-type region 8 are then diffused into the base region. Emitter region 7 is located near one end of base region 2 so that the edges of region 8 contact collector region 1 thus burying part of the base region. This increases the basecollector capacitance without a substantial increase in leakage current. Ohmic contacts 3, 4 are applied to base region 2 and emitter region 7 and the end of arm 5 of base region 2 remote from the emitter is shorted to the collector by contact 6. The collector contact is applied to the lower face 9 of wafer 1. The diffusions are performed using photo-masked oxide diffusion masks, the N-type impurity being boron, and the P-type impurity being phosphorus. Arm 5 of base region 2 may alternatively have a serpentine shape. The device may be utilized in a circuit for an electrically maintained mechanical resonator (see Division G3).

Title: Electric discharge apparatus particularly for the generation of high potentials
IPC: H05H9/00
Filed: 1944-02-18
Abstract: 590,594. High - frequency discharge apparatus; detectors. WESTERN ELECTRIC CO., Inc. Feb. 18, 1944, No. 3107. Convention date, Feb. 5, 1941. [Classes 39 (i) and 40 (v)] A high potential generator comprises a number of electrodes 14 ... 17, Fig. 1, through which a beam of electrons passes to a collector electrode 12. The electrodes are interconnected by biassing resistances 20 and are energized alternately in phase opposition through condensers 21 from a high-frequency oscillator 23. When the device is in operation, the D.C. potential difference between successive electrodes is equal to the amplitude of the high frequency oscillation and the time of flight of an electron through an electrode is equal to one half-cycle. As a result, an electron leaving the accelerating grid 13 when the potential of electrode 14 is a minimum, passes into electrode 14 without acceleration. This process, which is illustrated diagrammatically in Fig. 2. is repeated between successive electrodes until finally the electron arrives at collector 12, the most negative electrode, without any substantial variation of velocity. The flow of the collected electrons through the resistances 20 biasses the electrodes automatically to the correct potentials. The potential of electrode 12 follows the variations in amplitude of the highfrequency supply so that, by modulating this supply with a signal, the device may be used as a detector. By providing an aperture in collector 12 and putting an earthed X-ray target behind, part of the electrons may be used to generate X-rays, being accelerated directly by the high potential generated. In a modification, the electrodes may be supported by discs 25, Fig. 3, extending outside the envelope, and forming with flanges 26 a series of cavity resonators which are so coupled by loops or apertures (not shown) that they oscillate in anti-phase. A small amount of gas may be introduced into the discharge device. Heavy ions may be used instead of electrons.

Title: Improvements in methods of and machines for making knitted fabric and stockings
IPC: D04B1/26
Filed: 1933-02-03
Abstract: 408,084. Knitting. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; 55, Cooke Street, Pawtucket, and Cloutier, A. N. ; 495, Broad Street, Lonsdale, both in Rhode Island, U.S.A.) Feb. 3, 1933, No. 3365. Convention date, March 8, 1932. [Class 74 (ii).] Relates to a method of changing from rib to plain knitting upon a circular machine having an auxiliary thread feeder and knitting cams arranged at a position substantially diametrically opposite the main thread feeders and knitting cams. The rib knitting is performed by the dial needles 23 and the intermediate cylinder needles 41 at the auxiliary feeder 33, and after completion of the last rib course the dial needles 23 retain their loops until four courses, 47, 48, 49, 50 of plain knitting have been made. The courses 47, 49 are knitted at the auxiliary feeder, and the courses 48, 50 are knitted at the main feeder 17. At the next course 51, the cylinder needles corresponding to the rib needles hold their loops, and the rib needles knit, the loops 46 formed thereby being elongated by the rib needles taking up thread from the adjacent cylinder needle loops. A plain course 52 is then knitted by all the cylinder needles at the main feeder, and the dial needles continue to knit for one or more courses 53 to provide a tab or extension 15. The course 52 is followed by the plain courses 54 which constitute, e.g. the leg and foot of a stocking. The invention is described in connection with the knitting of a stocking or fabric having a selvage which does not curl or roll. Loopers' rounds 10 are knitted with a comparatively loose stitch, followed by accordion fabric 34. The last accordion course is knitted at the main feeder, and immediately after the loops have been drawn, the main yarn feeder is withdrawn, and the needles 41 intermediate of the rib needles receive thread and knit at the auxiliary feeder with the rib needles, the cylinder needles being actuated at the auxiliary feeder to cast off their loops. A pull course 11 is thus formed. Following the selvage course 42 a French welt 2, or a tuck, half-round, or a turned welt may be provided. Anti-ravel courses 64, Fig. 23, may be formed by causing the rib needles to knit the thread at the auxiliary feeder and all of the cylinder needles to knit at the main feeder.

Filed: 1960-02-01
Abstract: 881,030. Paper-making machines. BELOIT IRON WORKS. Feb. 1, 1960, No. 3492/60. Class 96. Apparatus for installing an endless wire in a papermaking machine includes means for rotatably mounting the wire rolled into a bundle and means for supporting a plurality of wiresupport members for carrying a loop of wire unwound from the bundle, the wiresupport members being arranged to be suspended so as to be capable of movement along the machine in order to elongate the loop. One form comprises the assembly 14 shown in Fig. 1 comprising spaced parallel side frames 15, each having a horizontal portion 17 with depending legs 36, 37 and a standard 19a with supporting eye bolts 30. The standards each carry a mounting for a bearing 20 to which is attached a clamp 21 to secure the ends of the core members 11, 12 on which the wire bundle is wound. A number of poles 13 used to support the wire during installation are supported by their ends on tracks 18 on the frames 15. Rollers 46, 47 on the standard 19a facilitate positioning the poles. Other poles may be placed in clips 38 on the legs 36 and may be secured by links 39, or between prongs 41 on the leg 37 and may be secured by a bar 42. During installation, the loop at the outside of the wire bundle is enlarged and passed round poles in the clips 38 and prongs 41. The whole assembly 14 can then be moved sideways on an overhead track to enclose the cantilever mounted rollers A, B within the loop of the wire. A number of polecarrying assemblies 49 . . . 53, Fig. 6, are provided, all suspended from carriages running on a track 48 and provided with pairs of U-shaped members in which the ends of poles may be secured. Two poles, from a supply carried on the tracks 18, are fixed to the assembly 49 within the loop of the wire which is then pulled out by a rope 58. Two poles are attached to each supporting assembly in turn, one from the tracks 18 within the loop and one, for example, from the prongs 41, outside the loop. The assemblies are interconnected by lines 55a &c. to ensure that they open out to equidistant positions. When the wire is fully extended, one pole from the support 49 is attached to the upper part of the machine pedestal 59 and one is lowered on to supports 64. The lower pole on each other support is also removed. The core members 11, 12 are removed from within the wire and the poles from the members 36, allowing the wire to rest on the rollers A, B. The wire supports may carry additional poles, e.g. at 51m, which may be removed and used as weights to depress particular parts of the lower run of the wire to facilitate reassembly of the machine. If it is required to lift the upper run, this may be done by pulling backwards on the line 72 to pull the carriages along the track 48. All except that of the support 49 are interconnected by lines 54a &c. ; since the support 49 is anchored to the pedestal 59 the supports lean backwards and lift the poles at their lower ends.
