Title: Capacitors
IPC: H01G9/008
Filed: 1971-04-19
Abstract: 1339166 Electrolytic capacitor UNION CARBIDE CORP 19 April 1971 [2 March 1970] 22766/71 Heading H1M A solid electrolytic capacitor 26 processed from a porous body of anodizable metal by standard methods is hermetically sealed within a metal can 25, initially open at both ends by first bonding a header of insulating material to the top of the casing by means of a metallized margin 33 on the header, passing a length of solderable metal wire 45 through a metallized aperture 40 in the header and welding it to the anode lead, positioning the capacitor body 26 as close to the header as possible, solder sealing the other open end of the can 25 so that solder 54 also holds the capacitor in place, solder sealing wire 45 to the metallizing in the aperture 40, and connecting a second solderable metal wire 56 to the header at a position insulated from the first wire 45 and providing electrical connection between it and a silver or like coating on the capacitor body. Since the top of the can is sealed before the capacitor is inserted high temperature soldering or brazing may be employed and a more reliable seal, which may moveover be tested before further processing, is obtained. As shown, the header sits on the top of the can, but alternatively, it may be inserted into the can and its side surfaces bonded thereto (Fig. 3, not shown). As shown, the metallized margin of the header is continued over its top surface to cover the site of attachment of cathode lead 56 to provide its electrical connection (see also Fig. 1, not shown). Alternatively (Fig. 6, not shown) the cathode lead may be more securely attached by passing it through a second metallized aperture in the header and metallizing on the undersurface of the header provides electrical connection. In another embodiment the cathode lead is connected directly to the capacitor body (Fig. 4, not shown) suitably by passing a hairpin shaped nickel wire through two metallized apertures in the header, connecting one end to the anode lead, the other to the capacitor body, positioning the capacitor body, solder sealing the two wires and severing the bight portion. Suitably the locations of the anode and cathode leads are a standard distance apart for use with a printed circuit board.

Filed: 1935-08-20
Abstract: 440,715. Fire - control apparatus. NAAMLOOZE VENNOOTSCHAP NEDER. LANDSCHE INSTRUMENTEN COMPAGNIE, NEDINSCO, 9, Molensingel, Venlo, Holland. Aug. 20, 1935, No. 23338. Convention date, Sept. 11, 1934. [Class 92 (ii)] [See also Group XIX] A fire direction control device for anti-aircraft guns comprises means for determining the lead corrections to be applied for counteracting the influence of the wind. The means described includes two sets of rotatable and displaceable cam members which control the adjustment of slidable members that cooperate with multiplying gears to give the corrections. For apparatus mounted on board ship, a third set of cams is provided to compensate for the ship's movements. In the form shown in Fig. 2, shafts 2 and 7 are rotated in accordance with the magnitude of the velocity and direction of the wind so as to position a set of cam bodies 11, 12 connected by a sleeve 10 and slide 13. The cams are so constructed as to effect the displacement of slides 21, 22 in accordance with the rectangular components of the wind values in a horizontal plane at right angles to the plane of sight, one axis being in alignment with the horizontal range. Shafts 3 and 8 are rotated in accordance with the speed and direction of the ship's movement so as to adjust a set of cams 14, 15 connected by a sleeve 13<1> and slide 16. These cams are constructed to impart movements to slides 23, 24, corresponding to the components of the values in the plane above referred to. The range and altitude angle are transmitted to shafts 9 and 4, to adjust the position of interconnected cam bodies 18, 19 co-operating with slides 25, 26 to effect their displacement according to amounts, by which, the range and lateral angle must be rectified per unit of wind velocity, for a definite kind of projectile. The slide 21 has pivoted thereto a lever 27 which coacts with the slides 23, 25, and with another slide 30. The slides 25 and 30 are provided with racks engaging pinions 38, 41, on shafts of a multiplying gear 39 which function to determine the lateral angle correction by the rotation of a shaft 42. The other slides are associated with another multiplying gear 45 which actuates a shaft 48 to determine the alteration in range. Additional mechanism, as shown in Fig. 3, is provided for ascertaining the altitude angle adjustment and comprises a third cam body 49 on the shaft 4 and operative connections 53-55 and 57-59 with a multiplying gear 56 operating a shaft 62 to give the correction.

Title: Improvements in or relating to filter presses
Inventor: JOHN WILLY
IPC: B01D25/172
Filed: 1965-06-01
Abstract: 1,096,719. Opening of filter presses. E. NETZSCH [trading as GEBRUDER NETZSCH MASCHINENFABRIK]. June 1, 1965, No. 23406/65. Heading B1D. A slide 7 is movable along a slideway 24 by a cable 6 forming part of an endless loop about an electric motor drive at one end of the press and a pulley at the other end. Space for the slide is provided between the top of each filter plate (e.g. 11, 18) and a pin (e.g. 12, 17) extending transversely between two hangers by which the plate is suspended from a rail 2. A toothed segment 8 pivoted on the slide 7 is normally urged by a spring 19 into the attitude shown in Fig. 5. To withdraw a plate from right to left, the slide is moved to the left. Tooth 9 encounters pin 12 on plate 11, whereby the segment is rotated clockwise against spring 19 to the attitude shown in Fig. 4. When tooth 16 encounters pin 17 on plate 18, the resistance (provided by the stack of contacting plates to the left) is such that the electric motor is automatically reversed. As slide 7 begins to move to the right, tooth 16 is freed from pin 17, whereupon spring 19 rotates segment 8 to the attitude shown in Fig. 5. Tooth 9 is accordingly able to engage the left hand side of pin 12 on plate 11; the resistance of this one plate free to move is insufficient to effect reversal of the motor, and plate 11 is accordingly impelled to the right. When the Fig. 5 position is reached, the resistance to slide 7 provided by end plate 3, fixed temporarily by a hydraulic device, suffices to effect motor reversal once more. The above sequence is then repeated to withdraw plate 18, and so on. The slide 7 is provided on its remote side with a similar segment and spring (not shown). The drive and reversing means may be wholly mechanical. The reverse means may alternatively be hydraulic or pneumatic.
