Title: Interconnection by bonding of stacked sheets
IPC: H05K3/46
Filed: 1968-08-27
Abstract: 1,234,821. Metal laminates. BUNKERRAMO CORP. 27 Aug., 1968 [8 Sept., 1967], No. 40837/68. Heading B5N. [Also in Division B3]  An assembly comprises at least two stacked sheets bonded together over a predetermined surface area portion, a plurality of grooves being formed in each opposed surface to define a plurality of ribs and a bonding agent being disposed in the grooves to bond the sheets together. The opposed surfaces are arranged so that the grooves are perpendicular to one another and portions of the ribs engage, anomolies on the tops of the ribs having been removed by ductile movement of rib material. In a circuit structure 10, Fig. 1, comprising aluminium, copper, silver, gold, magnesium or steel sheets 11, 12, 34 of thickness from 1 mil. or less to greater than 0À05 inch, bonded together and having a circuit pattern provided by leads 14 in etched vertical channels 25 filled with dielectric material 13, horizontal leads 14<SP>1</SP> and a lead 14<SP>1</SP> in a horizontal channel 26 filled with dielectric material 27, the sheets are bonded together by means of solder, epoxy loaded with conductive material or a non-conductive resin. When non-conductive bonding material is used conductive mating surfaces e.g. gold are under pressure contact. Each facing surface of sheets 11, 12, 34 and of adjacent leads is chemically etched to provide grooves 17, Fig. 5, the dielectric material 13, 27 not being affected. A plating layer 22 may be provided on one of the facing surfaces, the grooves are coated with resin-based flux and a molten lead-tin alloy solder 18 (shown in exploded view in Fig. 5) is caused to fill the grooves. Excess solder is removed by a squeegee and excess flux by alcohol. The sheets are then arranged with the grooves on one sheet at right angles to those on the adjacent sheet and under the application of heat and pressure bonding between the sheets and grooved leads is effected.

IPC: H02G7/12
Filed: 1963-10-21
Abstract: 1,098,813. Spacing overhead conductors. ALUMINIUM WIRE & CABLE CO. Ltd. [Oct. 21, 1963], No.41504/63. Heading H2C. A cable spacer for bundled overhead conductors has clamps pivoted to the spacer arms by members which are placed in shear by relative longitudinal movement of the conductors. The figure shows an H-shaped spacer in which the four conductors to be spaced are mounted in clamps 1. The clamps themselves are attached to the ring members 4 which are mounted between the jaws formed by the upper and lower members 23, 24 of the spacer arms. The inner faces of the jaws are provided with sloping annular faces as are the inner faces of the rings. Between these faces are two rubber or synthetic rubber elements 12 which carry nibs 19 engaging in faces of the jaws and rings. Thus if one cable moves longitudinally relative to the clamp, rubber member 12 is placed in shear. Any other movement introduces at least an element of compression. A similar arrangement is employed for attaching the arms of the H to the cross pieces 25. The rubber member 12 may consist of a number of parallel sections with metal or cloth inserts. An arrangement is also described (Fig. 6, not shown) in which the spacer is X-shaped, the rubber shear member being mounted between the clamp and a central piece carrying four sets of jaws. Stops are provided to limit the clamp movement but in the latter embodiment the rubber members are bonded to the jaws. The jaws may be carried by the clamps (Fig. 7, not shown).

Abstract: 1,066,059. Rotary-piston I. C. engines. CURTISS-WRIGHT CORPORATION. Oct. 22, 1963 [Nov.2, 1962], No.41708/63. Heading F1F. In a rotary-piston I. C. engine of the trochoidal n and n + 1 lobe type, fuel is injected through a nozzle (44), Figs. 3 and 4 (not shown), at an angle of 0 to 10 degrees of arc relative to the adjacent working face of the piston (16) and in the direction of the motion of said face, injection being initiated substantially before the piston reaches a top-deadcentre position and sustained until the piston is at or near said position. The injected fuel is deposited on said face of the piston, which face includes a recess (70), and the fuel is thereby vaporized to effect a combustible mixture with air compressed within the corresponding working space or chamber, ignition of said mixture being initiated by a spark-plug (46). The nozzle may be situated in either the peripheral wall of the housing or one of the end walls or side housings, Fig. 8 (not shown). Alternatively, the jet of fuel issues from the nozzle in opposition with the motion of the adjacent working face of the piston, Figs. 5 and 6 (not shown).

Title: Process for the production of finely-divided copper oxychloride
IPC: C01G3/06
Filed: 1961-11-30
Abstract: Finely-divided copper oxychloride is prepared by oxidizing cuprous chloride in an aqueous medium, which may contain sodium chloride, with an oxygen-containing gas, intensive mixing of the aqueous and gaseous phases being effected by cavitation of the gas bubbles in the aqueous medium.  The concentration may be 50-300 grams of copper per litre as cuprous chloride. Hollow stirrers, preferably with prismatic stirrer elements, which can draw air into the solution, or turbine-like stirrers with drilled apertures for passing gas, may be used.  The temperature may be from room temperature to the boiling point of the aqueous phase.  A suspension of crude cuprous chloride purified by screening out coarser impurities and by hydrocyclone treatment may be used.  The cupric chloride produced in the process may be converted, when sodium chloride is not used in the aqueous phase, to copper oxychloride by the addition of alkaline earth oxides, hydroxides or carbonates.  In Example 1, a cylindrical vessel with four internal vanes is provided with a square stirrer of 60 mm. diagonal and 10 mm. height with 4 holes passing from the centre to the edges with the location of discharge immediately behind the edges in the direction of rotation. The shaft is hollow.  A cuprous chloride suspension is prepared in the vessel, and at 3500 r.p.m. the stirrer draws in 2500 litres of air/hour and distributes it uniformly in the suspension.  At the end of the reaction, the product is filtered, washed and dried at 110 DEG  C. Example 2 is similar, using a stronger cuprous chloride suspension.
