Title: Soldering Flux and Method of Soldering
IPC: B23K35/36
Filed: 1968-08-28
Abstract: 1,181,753. Soldering. ALUMINUM CO. OF AMERICA. 28 Aug., 1968 [14 Sept., 1967], No. 41185/68. Heading B3R. [Also in Division C7] A soldering flux for soldering, e.g. Al and Cu, contains zinc chloride and 0À5-33% by weight ammonium fluoborate and optionally 0À5-25% ammonium chloride. The flux may also contain other metal halides such as stannous chloride and cadmium chloride and ammonium halide other than the chloride. The flux may be used as a powder, paste or liquid formed by solution in a short chain aliphatic alcohol such as methyl, n-propyl, iso-propyl or n-butyl alcohol. The flux is particularly effective in dip soldering Al or Cu stranded cable components which are first dipped into the liquid flux prior to dipping into solder such as 35 Sn-65 Zn or 40 Sn-60 Zn.

Title: Mounting electrodes in electrolytic baths
IPC: C25C3/10
Filed: 1963-10-18
Abstract: <PICT:1032810/C6-C7/1> <PICT:1032810/C6-C7/2> An electrolytic bath, e.g. for producing Al from Al2O3 has means for suspending electrodes so that they can be moved vertically as required. Figs. 1 and 2 show a bath 100 for producing Al which has carbon cathodes blocks 119 on Fe bars 118 and movable anodes 120.  A hood comprises a fixed central portion 151 and four pivoted portions 152, 153, Fig. 1, and 154, 155, Fig. 2.  Baths are connected in series by conductors 130, 140.  The movable anodes 120 are suspended by anode rods 121 clamped to a lower fixed frame 210 and also to an upper vertically movable frame 220. To lower the anodes and so adjust the anode-cathode spacing 1) the clamps on the fixed frame are loosened, 2) the movable frame is lowered, 3) the clamps on the fixed frame are tightened and, to return the movable frame to its original position, 4) the clamps on the movable frame are loosened, 5) the movable frame is raised and 6) its clamps are tightened. Electrical connection to the anodes is by clamping the anode rods 121 to bus bars which, as shown, comprise cladding on the sides of the frames.  Each clamp 240 (Fig. 9, not shown) includes a movable jaw.  241 acted upon by a resilient force-transmitting mechanism 242,243,245, 244 operated by a control member 248 common to a plurality of clamps carried by one frame, each control member being controlled in turn by a rotary cam (e.g. 262 Figs. 10 to 13 not shown), the or each cam associated with the fixed frame being offset angularly in relation to each cam associated with the movable frame, so that as the cams are rotated, the two clamps associated with each movable electrode are never concurrently unclamped. Details of the mechanism for vertically moving the movable frame are illustrated in Fig. 8 (not shown).  At times when it is necessary to add Al2CO3 to the bath to stop an "anode effect" one of the smaller end panels of the load is raised to allow the addition (Fig. 7 not shown).

Abstract: 1,072,006. Automatic exchange systems. SIEMENS A.G. Sept. 29, 1965 [Sept. 29, 1964; Aug. 4, 1965], No. 41297/65. Heading H4K. Codes of an unspecified sort, received over lines Lan 1 to Lan n, are converted to voicefrequency codes, for transmission over lines Lab 1 to Lab n, by common equipment having a highway MS whereby a single set of voicefrequency generators TG are time shared for the transmission of codes and a single code converter V is time shared for the reception of codes. As shown in Fig. 1, the lines Lan have a fixed association with respective outgoing lines Lab. An address generator AGU and decoder DU cyclically scans the circuits U1 to Un, at the junction between incoming and outgoing lines, so that in each time slot a code of the unspecified sort, if present at the input to one circuit U, is gated to the converter V and the output of that circuit is gated to the highway MS. The address or addresses of voice-frequency generators required for the corresponding transmitted code is sent from the converter V to a circulating store S where over a decoder DG they gate the generators to the highway MS. The store S may contain data which directs the converter V as to conversions particular to circuits U. There may be fewer time slots on the highway MS and in the store S than there are circuits U, the circuits U being scanned for codes on lines Lan which are then allocated a time slot for conversion. As shown in Fig. 2, the codes of unspecified sort are received in circuits EU1 to EUN for transmission by any one of circuits AU1 to AUn, a speech path being set up between the receiving circuit EU and the transmitting circuit AU over a switching network K. The circuits EU may outnumber the circuits AU and in place of the space divided network K a time division network may be used. The circuits EU may be subscriber's line circuits and the circuits AU may be outgoing to other exchanges. Codes detected in a circuit EU are converted in the common equipment which controls the gating of the voice-frequency generators TG to the highway MS and from the highway MS to the associated circuit AU.

The position of a control member 3, e.g. a fuel injection pump control rod, actuated by a centrifugal governor 14, is adjusted by a barometric capsule 12 which is not opposed by the force of the governor. The governor 14 actuates a lever 4 which is resiliently connected to the rod 3 through a shaft 19 sliding in a block 18 on the rod, a light spring 20 normally holding the block 18 against a stop nut 22 on the shaft 19. The capsule 12 acts upon the rod through a member 13 and adjusts the rod 3 relative to the shaft 20 against the force of the light spring 20 only, the maximum adjustment being limited by a shoulder on the shaft 19. A hand lever 5, connected to the lever 4 through a spring 6, superimposes a manual control upon the governor control.

Abstract: 1465849 Coating cans KAISER ALUMINIUM & CHEMICAL CORP 23 Sept 1974 [27 Sept 1973] 41380/74 Headings B2E and B2C [Also in Division B8]  Apparatus for coating cans with organic polymer material includes precoating wash and rinse stations and a spray station and which the inside and outside of the cans are coated simultaneously while being stabilized by the force of the spray on the closed end of the inverted can. Cans are advanced on a meshwork conveyor 10 through a wash and rinse station 4 to a station 5 at which they are sprayed with di-ionized water. They are guided throughout by lateral wires 200. The cans pass a baffle 19' onto a dead-plate 65 which may be agitated, and supplemented by a hold-down conveyor engaging the can ends. At station 6 most of the moisture is blown off, however sufficient surface moisture remains to enhance subsequent adhesion of the coating.  The cans are pushed onto a second conveyor 10', driven at the same speed as the first, by a waffle roller 46 for advance through coating and blow-off stations 7, 8. The upper run of the conveyor is raised by a roll 104 to separate the cans after coating, and may be agitated by cams on the idle roller 38. The insides and outsides of the cans are simultaneously deluged by upper and lower, fullcone sprays 67 of an organic polymer dispersible in an aqueous medium. The polymer has a molecular weight of between 200 and 30000 and may be epoxy- or polyester epoxytype or acrylic type. The pressure of the upper sprays is greater than the lower so that the cans are stabilized. Waste spray material is collected in tank 84.  The cans are pushed across a dead-plate 72, similar to plate 65, the leading edge of which scrapes excess material from the rim of the cans, and onto a third conveyor 10" moving faster than 10'. The cans are thus spaced as they progress through the hot-air curing oven 70. A raising roll 104' is also provided.

A vacuum tube grid is made by staking wires 36, 37 into grooves on opposed legs of a frame 27 such that each groove is deformed only along part of its length. The wires are supplied from spools 39 and tensioned by a jig 38. The grooves are formed by machining or chemical or anoidic etching. The sides of the grooves are inclined at 55 degrees, the wires are preferaby stainless steel and the frame is soft iron. The stacking deforms either the outer part of the groove 46 or a central portion. A tool (42), Fig. 10 (not shown), is moved across the grooves to stake the wires in the grooves. Alternatively a tool (43), Fig. 11 (not shown), is vibrated at supersonic or lower frequencies as it is moved across the grooves. The direction of reciprocation may be at 45 degrees to the normal, Fig. 12 (not shown). A prior art method of making a grid is described, Figs. 1-4 (not shown). This includes securing the wires to the grid by an adhesive and coating the adhesive in silver.
