Title: Display apparatus
IPC: G01S19/15
Filed: 1970-10-07
Abstract: 1328677 Cathode-ray tube displays; pulse amplitude limiting SPERRY RAND CORP 7 Oct 1970 [8 Oct 1969] 47796/70 Headings H3T and H4T Altitude display apparatus for a mobile craft, specifically an aircraft, comprises means for intensity modulation of a spirally scanned time base on a display cathode-ray tube. The display thus produced comprises a horizon 12 (Fig. 1), runway 13, in a single point perspective and ground plane grid 14, also in perspective. Additionally, during the fly-back intervals of the spiral time base, deflection-modulation of the beam is employed to trace horizontal and vertical flight director bars 15 and 16 respectively together with a centre reference marker 17. Fig. 2, shows the general arrangement of the spiral time base generator (which produces an interlaced scan) the detailed circuit of which is given in Figs. 4a and 4b and Fig. 34 shows the overall scheme employed in the production of the display, the various "blocks" of the latter figure also being given in circuit diagrams. Fig. 3, shows the general form of the voltage controlled symmetrical limiter 21 (Fig. 2) in which the level of the output E OUT  derived from the square wave input E IN  from generator 20 is limited by the input to amplifier 30 from ramp generator 22 (Fig. 2). The detailed circuit is shown in block 21, Fig. 4b. The horizon 12 is produced by blanking the beam for one half of its period (i.e. 180 degrees) and by varying the phase of the blanking pulse as a function of roll # the horizon, i.e. 50% of the spiral raster, rotates about the centre of the raster. When, however, lateral deviation X and/or pitch # inputs are present, correct perspective is maintained by causing the rotation to occur about the centre of the display (Figs. 26a and 26b). The runway 13 is produced by a bright-up pulse having a width of 15 degrees and consists of a wedge shaped area the "vanishing- point" of which is situated at the centre of the raster and the perspective of which is controlled by the variable parameters a, b, Á and T derived from the aircraft position and altitude relative to the runway as defined by ILS beams and by the aircraft heading. The ground plane grid 14 is produced and its perspective is controlled in a generally similar manner. After fly-back of the beam has occurred a period of about eight cycles of the time base is allowed for the various filters to recover from the retrace transient and during this period the centre cross mark 17 and the flight director bars 15 and 16 are traced by the application of sinusoidal voltages to the X and Y deflection circuits, the position of the bars 15, 16 being determined by input voltages e and g respectively (Figs. 31a and 31b). Pitch motion # and lateral deviation X are displayed by vertical and lateral movement of the raster as a whole only a portion of the raster being visible in a viewing area (Figs. 9 and 10).

Abstract: 1,028,506. Sewing machines. PRICES TAILORS Ltd. Dec. 29, 1964 [Dec. 6, 1963], No. 48211/63. Heading D1G. The stitch length in a sewing machine is changeable in the same direction by means in operative association with the lever for reversing the stitch direction and operable between fixed limits by a pedal, knee lever or the like, whereby the operative can move the reverse lever temporarily to a predetermined position to deter the stitch length, and can quickly cause the lever to revert to the normal stitch length position. As shown, the feed control lever 1 is normally spring- biased to a pre-set upper position corresponding to long stitches (e.g. 4 per inch). A rod 4, slidable in a fixed bracket 5, carries at its lower end an adjustable nose 3, and carries above bracket 5 an adjustable collar 8. A spring 6, acting between bracket 5 and a collar 7 on rod 4, biases the latter downwards to engage collar 8 with bracket 5 and to depress lever 1 to a pre-set position corresponding to short stitches (e.g. 14 or 16 per inch) which constitute the normal stitch length. Rod 4 is connected by a flexible cable 9 to a treadle which, when depressed, raises rod 4 to allow lever 1 to assume the long stitch position. The upward movement of rod 4 may be limited by a further collar 11 provided thereon. Lever 1 is movable at any time in the reverse stitching direction.

Abstract: 1,212,771. Proximity sensers. WAGNER ELECTRIC CORP. Oct. 11, 1968 [Oct. 12, 1967], No. 48284/68. Addition to 1, 195, 288. Heading GIN. A capacitive sensor for an automatic urinalflushing system includes, inside a ceramic casing 10, electrodes 14, 16, and 30 which form first and second capacitors 14, 30 and 14, 16 respectively, a component #, C, of the capacitance of the first being variable in accordance with the proximity of a moveable object to the antenna electrode 14. Electrode 16 attains a potential between that of earth and the antenna thus acting as an electrostatic screen against spurious signals caused for example, by passers-by. Additionally the earth electrode 30 is extended at 38 to screen the antenna from capacitance charges caused by water flowing from the pipe 52. Alternatively the part 38 may be omitted and its function usurped by a conductive strip 11, engaging the bottom edge 12 of casing 10, being earthed by an extension 13 contacting electrode 30. Thus a stray antenna-earth capacitance component # 2 C 1  remains substantially constant since the intervening ceramic casing is of high relative permittivity. A required capacitance charge is coupled by a coaxial cable 22 to amplifying and switching circuits which control the operation of a flushing valve 42. For calibration purposes a variable capacitor # 3 C 2  is connected between inner 26 and outer 24 conductors of the coaxial cable.

Washer 20 has a part-spherical boss 21 which projects into undercut 19 with its opposite surface 22 dished and bearing on the resilient washer 23, the dished shape helps to exert extra pressure on the periphery of washer 23. The washer 23 has a rib 24, grooves 34 and a boss 25. A thin washer 36 is located between washer 23 and thread 14, to prevent damage to washer 23 by the container or thread 14 during operation.  To operate the device spike 10 is forced into the container until thread 14 engages. Screwing of the device pulls it into the container, the seal eventually contacting the container surface. Further screwing locates the backing washer into the undercut 19 resulting in the rib 14 being pressed on to the container to give a good peripheral seal. The boss 25 is also compressed and gives a radial seal around member 11. The annular grooves 34 contact washer 36 and force it firmly against the container surface, and allow sealing without undue deformation of the whole washer 23. The engagement of boss 21 with undercut 19, can accommodate a crooked position of the device or uneven container surface and still maintain an effective seal of rib 24 on the container.

Title: Production of oligomers of butadiene (1,3)
IPC: C07C11/21
Filed: 1963-12-20
Abstract: Cyclic olefins are obtained by oligomerization of butadiene in the presence of a catalyst formed from nickel carbonyl and a polyolefinic or acetylenic compound while keeping the concentration of carbon monoxide low during the formation of the catalyst and during the reaction, e.g. of the order of 0.066% referred to the oligomerization mixture.  The unsaturated component is preferably a hydrocarbon but may contain carboalkoxy or acyloxy groups; butadiene is particularly preferred. 1-400 mols of unsaturated compound is used per mol of nickel carbonyl and the catalyst may be formed in a hydrocarbon or ether solvent at 0-200 DEG  C. and 1-25 atmospheres.  Concentration of carbon monoxide is kept low by removal of gases continuously or at intervals or when the catalyst is formed in situ from nickel carbonyl and butadiene by having a low concentration of nickel carbonyl, e.g. below 0.1% by wt. of the butadiene.  Otherwise the catalyst concentration may be 0.0005-5% and reaction is effected at 50-150 DEG C.  In one embodiment the reaction is effected in stages adding further butadiene at each stage.  Cyclooctadiene and cyclododecatriene are the principal products.
