Title: Improvements in or relating to laminated products
Inventor: KNEWSTUBB NORMAN WATSON
IPC: B32B27/00
Filed: 1949-06-23
Abstract: 680,437. Laminated fabric and paper. BAKELITE, Ltd. April 24, 1950. [June 23, 1949] No. 16754/49. Classes 96 and 140. Laminated products, e.g. sheets, are prepared by superposing fibrous sheets impregnated or coated with a thermosetting synthetic ;resin which still retains its flowability under heat to form a stack, placing on one or both surfaces of the stack a fibrous sheet which has been impregnated or coated with a thermosetting synthetic resin and heated so that the resin has lost is flowability under heat, and subjecting the entire stack with the surfacing sheets to heat and pressure to consolidate the laminations and harden the resin. Suitable resins are condensation products of aldehydes with urea, melamine or phenols, fast stoving resins being preferred, at least for the surfacing sheets. The stacks may be pressed between non- metallic surfaces, such as laminated boards, which may carry an embossed pattern; if embossing is not required, separating plates may be omitted. In examples, a stack is composed of sheets of kraft paper impregnated with an alcoholic solution of a resol made by reacting a mixture of cresols with aqueous formaldehyde in proportion greater than equimolecular, in the presence of sodium hydroxide, as catalyst, and dried for 5 minutes at 120‹C, and assembled between two sheets either of the same impregnated paper which had been dried for 15 minutes at 120‹C, after which treatment the resin had lost its .flowability, or of an absorbent wet strengthened kraft paper treated with a solution of a fast stoving melamineformaldehyde resin in a mixture of alcohol and water, and heated at 120‹C until the resin had lost its flowability. The stacks were then pressed for 30 minutes at 1,500 Ibs. per sq. in. between two fully cured phenol formaldehyde resin bonded laminated boards or plates, maintained at 160 ‹C, the pressure was then released, and the moulded laminated board removed while still hot. Specification 628,113 is referred to.

Title: Improvements in or relating to methods of, and devices for, the soldering of semi-conductor crystals
IPC: H01L21/60
Filed: 1960-05-12
Abstract: 945,115. Soldering. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 12, 1960 [May 12, 1959], No. 16805/60. Heading B3R. [Also in Division H1] In a method of soldering a semiconductor crystal to a disc on the end of a wire sealed through a glass bulb a plate of solder is held between the crystal and disc by pressing a tube slidable relative to the bulb against the crystal. A non-oxidizing atmosphere is supplied to the interior of the bulb through the tube and then heat required for the soldering operation is supplied via the tube and wire simultaneously. In one method the bulb is mounted open end uppermost with the solder plate and crystal on the disc and the tube inserted into the bulb and pressed against the crystal. The soldering operation may alternatively be carried out in the apparatus illustrated in Fig. 4 which comprises a tube 30 with a recess 38 (Fig. 4a) in its upper end for holding the crystal and solder. The position of this tube and associated parts through which non-oxidizing gas is supplied, shown in more detail in Fig. 4a, is determined by an adjustable stop 39. The apparatus also comprises a fixed heating coil 52, a pivotally mounted open - sided heating coil 61 described with reference to Figs. 4b and 4c (not shown) and mechanical means for applying pressure to the wire. In operation the crystal and solder are first placed in that order in recess 38. Pressure member 70 is raised and coil 61 swung into position 61b by an upward movement of cam-operated rod 47 against the resilience of spring 49 to enable the glass bulb 5 (Fig. 2a) to be placed over tube 30 with disc 4 located in recess 38. Further movement of the cam allows rod 47 to assume its original position with the coil embracing the wire in position 61a and the pressure member 70 bearing on the end of the wire. To avoid shock loads on the wire during this movement the end section of the pressure member may be resiliently mounted as shown in Fig. 4d. After the bulb has been flushed out by a flow of non-oxidizing gas through tube 30 coils 52 and 61 are energized to supply heat via tube 30 and the wire, respectively, to complete the soldering. A machine for mass production, shown in Fig. 5, includes a rotating table 75 carrying a multiplicity of apparatus 76 of the above type to which crystals and solder plates are automatically fed from containers 78, 79, respectively. The glass bulbs, carried in holders 85, are positioned in the apparatus by arm 90 and, after soldering, are removed therefrom and replaced in the holders by arm 92. The stepping movement of the holders by a pawl mechanism is synchronized with the movement of the tube to allow this.
