Title: Improvements in or relating to spinning nozzles
IPC: H01J37/31
Filed: 1954-04-15
Abstract: <PICT:0754866/IV(a)/1> A spinning nozzle comprises a plate of quartz or quartz glass having orifices formed by locally evaporating the material by means of a high energy electron beam in a high vacuum.  A suitable beam intensity is of 2 mA. having a voltage drop of 100 KV, the "drilling" being effected at a pressure of 1 mm. of Hg.  The quartz plate is "drilled" in the same direction as the spinning material is to pass through the orifice and so that the orifice is tapered towards its discharge end.  As shown in Fig. 3, the walls 52 of the orifices so formed in the quartz plate 50 are preferably curved asymptotically towards their outlets 53.  The quartz plate is preferably rotated during the "drilling" operation to ensure a symmetrically shaped orifice, and the several orifices in one nozzle are drilled according to an enlarged template by means of which the quartz plate may be accurately positioned in the path of the electron beam.  A suitable apparatus for effecting the "drilling" is shown in Fig. 3 in which a high voltage rectified current is used for producing an electron beam from the heated cathode 4, the beam 28 being concentrated by a Wehnelt cylinder 4a and passing through an earthed anode 5, adjustable aperture 6 and electromagnetic focusing coils 10 to the quartz plate 11 being "drilled."  The chamber 2b is maintained under high vacuum by a diffusion pump 13.  The chamber 2c is maintained under vacuum by pump 29 and is separated from chamber 2b by valve 7 which closes automatically when pressure in chamber 2c is greater than that in chamber 2b, so as to preserve the vacuum in the latter.  Quartz plate 11 being "drilled" is mounted in a chamber 1 so that it can be moved by control 27 from the outside, and its movements may be guided by template 27a to ensure the several holes being "drilled" in their correct positions.  When a hole is completed, the electron beam strikes a collector electrode 20 located behind the quartz plate and this may be arranged to switch off the beam, through control gear 21; normally the beam is switched on and off by push-button 19 and control gear 18.  When the cover 22 of chamber 1 is opened, contacts 23b and switch gear 23 are actuated to open valve 8 to atmosphere, whereupon valve 7 automatically closes to preserve the vacuum in chamber 2b.  Switching is also arranged to ensure that whenever valve 7 opens, valve 9 is closed to isolate pump 29.

Abstract: 397,599. Bridge piers ; foundations. BRAITHWAITE & CO. ENGINEERS, Ltd., Broadway Buildings, Westminster, and YOUNG, R. V., Clive Works, Hilde Road, Kidderpore, Calcutta, India. April 20, 1932, No. 11348. [Classes 20 (i) and 20 (ii).] A bridge or like pier adapted to be located in a flowing stream or tidal river comprises two separate units 3, 4 arranged in side by side relationship with the outer faces of the units in line with the normal direction of the current and the inwardly-directed faces shaped so that the passage between them flares outwardly towards each end to occupy substantially the whole width of both the upstream and downstream ends of the pier. A number of preferred shapes for the units are shown in horizontal cross-section in Figs. 9 to 16. A pair of units may be surmounted by a capping 5 for carrying the superstructure 6, as shown in Fig. 1, or the two units may be entirely independent of each other. The foundation for the piers may comprise a large block of masonry with a hollow well at each end, or the units may be supported on a platform carried on a series of separate masonry wells or piles. The superstructure may, alternatively, be supported on two rows of cylindrical metal or concrete piles 12, Fig. 5, adapted to project through the units 3, 4. which are then formed of metal or other shells. When currents of variable direction are encountered, either the upstream or downstream vertical edges of the units, or both such edges, may be provided with movable vanes.

[Class 29] A zigzag shaped insertion member 11 for forming prism-shaped ice-blocks in a tray 16 is provided with ends 14, 15 adapted to grip over the ends of the tray, the member being stretched during engagement. The member is preferably of general curved form when detached so that the bottoms of the zigzags always contact with the tray when in place. The first ice prism may be detached by manipulating the overhanging part of the front edge 15 of the insertion member, after which the tray, which is of thin aluminium plate, may be flexed to detach the insertion member and all the ice prisms. Preferably several insertion members are used, separated by vertical longitudinal partitions. The ends of the insertion member or the edges of the tray, particularly at the front, are provided with knobs &c. 18 to space apart the engaging surfaces sufficiently to avoid capillary siphoning of water out of the tray. A prism of rubber may be placed in the front space 19 of the tray to prevent the formation of a rigid block of ice and to facilitate release of the insertion member.

[Class 74 (ii)] A fabric knitted upon a circular machine has wales LB formed of knitted loops spaced apart by more than one wale having a lesser number of knitted loops, some or all of such wales C, SB, having floats or tuck stitches therein. A 1x1 rib fabric so formed has an apparent change of rib effect, without changing the lay out of the needles. In the form shown in Fig. 1, the wales LB formed by long-butted dial needles of a rib machine have knitted loops at each course, whereas the thread is floated at each alternate course at each cylinder needle and at the short-butted dial needles, giving an imitation of a 2 x1 rib effect. As shown in Fig. 3, long-butted cylinder needles again form knitted loops at each course, while at the short-butted cylinder needles the thread is held at alternate courses to form tuck stitches, and at the dial needles D the thread is floated at alternate courses. By arranging the short and long-butted needles, various rib effects can be imitated. Specifications 267,876, [Class 74 (ii)], 437,992, and 446,784 are referred to.

Title: Data storage device

Filed: 1973-03-12
Abstract: 1371491 Semi-conductor capacitance memory cells NCR CORP 12 March 1973 [31 March 1972] 11757/73 Heading H3T [Also in Division G4] The binary digit stored on a capacitor 15 is remembered during power supply failures by appropriately setting the threshold of an adjustable threshold F.E.T. 10 connected to it. During normal write-read-refresh cycles, the F.E.T.s 10, 10a are enabled row by row by - 18 v. from 31 via switches 49, 29. Writing is by switching 1 or 0 potentials from 25, 25a, to the capacitors. Reading is by sensing with a differential amplifier 21, 21a, the stored voltages, allowing for the voltage drop due to line capacitances. Refreshing involves closing a switch 18, 18a to feed back the amplified 1 voltage, or zero, to the lines 28, 28a. Failure of power supply 50 is sensed at 59, and the switches 49, 29 are operated in response thereto, to apply to each row in turn, first + 30 v. from 35 and then - 30 v. from 37. The +30 v. presets the F.E.T. thresholds of a row from - 3 v. to - 2 v. by drawing electrons to the nitride-oxide interface of the M.N.O.S. F.E.T.s being used. The - 30 v. then develops a potential between gate and drain, the latter being connected to the capacitor store, which depends upon whether a 1 (-15 v.) or 0 (zero volts) was stored at the drain. If a 1, then the - 15 volt differential is insufficient to repel the stored electrons and the - 2 v. threshold is maintained. If a 0, then the - 30 v. differential does repel the electrons and a - 8 v. threshold is set up. When power supply is resumed, the F.E.T.s are enabled by - 18 v. from 31, and the write circuits 25, 25a supply - 18 v. to recharge the capacitors. The F.E.T.s with a - 8 v. threshold, however, permit only - 10 v. to be placed on their capacitors, while the - 2 v. threshold F.E.T.s permit - 16 volts to be stored. Allowing for line capacitances reducing these voltages during subsequent reading, the amplifiers 16, 16a distinguish them as 0, 1 voltages respectively, and refresh the capacitors correspondingly. In modifications, the capacitor stores may be the gate-source capacitances of further (normal) F.E.T.s (570, Fig. 6, not shown) which F.E.T.s can be made to conduct during reading (by 560) and the resulting currents monitored (578) to indicate the level of stored charge. In "two cells per bit" storage (Figs. 4, 5, not shown), pairs of capacitors store complementary binary levels and their read-refresh circuits employ bi-stables.
