Title: Manufacture of cellulosic pulp
IPC: D21C9/10
Filed: 1966-01-24
Abstract: Raw fibrous cellulosic pulp obtained in a chemical pulping process by the chemical digestion of a fibrous cellulosic material is passed to a first bleaching stage in which it is partially bleached with an aqueous solution containing chlorine or chlorine dioxide or both, the aqueous solution containing chlorine or chlorine dioxide or both is removed from the wet mat of partially bleached pulp, the partially bleached pulp is treated with hot alkali in a caustic extraction step, washed and passed to at least one further bleaching stage and a portion of the effluent from the washing of the extracted pulp is recycled to the mat of partially bleached pulp to displace water from the mat. The volume of effluent which is recycled is preferably not greater than the volume of water present in the mat thus displacing an equivalent volume of water from the mat and the partially bleached pulp is preferably washed before the recycled effluent is passed through it. As shown, in Fig. 1 partially bleached pulp is passed from a chlorinator through line 1 to washer 2 where it is taken up as a mat on the wire mesh periphery of rotating drum 3 where it is washed with hot water from a wire 4 and the effluent from the washer is drawn by means of a vacuum pump through line 5 to seal tank 6 to waste, and then passed to repulper 7 where it is mixed with sodium hydroxide solution entering through line 8 and steam entering through line 9 the hot mixture being then passed to caustic extraction tank 10 and washer 13 where it forms a mat on the wire mesh periphery of rotating drum 14 as is washed by means of hot water passing through line 15. The effluent from the washer 13 is drawn through line 16 to seal tank 17 a portion being pumped by pump 23 via lines 18 and 19 to the surface of the washed mat of pulp fibres on the surface of the drum 3 to displace the water from the mat which passes in a line 5 and seal tank 6 to waste, a portion is recycled via line 12 to washer 13 and returned to the seal tank, a portion is pumped by pump 20 via line 21 to extraction tank 10 and a portion is passed out through line 22 for recovery and reuse in the recovery stages for the overall pulping process.

Title: Atomizer for liquid
IPC: B41F7/30
Filed: 1967-04-19
Abstract: An atomizer suitable for spraying a liquid to damp a printing plate in an offset printing machine comprises a plurality of curved screens 23 mounted between a pair of rotating flange members 22 whereby they are sequentially immersed in the liquid 29 in a fountain 1, and a fixed compressed air distributer pipe 13 adapted to supply a stream of air which atomizes the liquid on the screen adjacent a rectangular discharge outlet 7. The screens are so mounted on the flanges by clamps 26 and screws 27 that the openings 24 between the screens are unobstructed. The air may be discharged from the pipe 13 through a plurality of nozzles 14 having convergent/divergent sections, Fig. 3 (not shown), or through an adjustable slot (14d), Fig. 4 (not shown), which is also provided with a convergent/divergent section. The pipe 13 may be curved so that the nozzles 14 at the end thereof are further from the adjacent screen and therefore atomize more liquid. This allows the ends of the printing plates to be more intensely damped. A member 30 removes surplus liquid from the screens and a cover 4 on the fountain is slidable so as to adjust or close the outlet 7. Slides 34 adjacent the outlet 7 may be raised or lowered with aid of a cam-shaft or punched cards in synchronism with the rotation of the screens. The slides, which adjust the opening 7, may be flat, arched, serrated or perforated. The screens may have a locally varying mesh size. The air may be discharged from the nozzles &c. in the sonic region.

Title: Method of providing contact leads for semiconductors
IPC: H01L23/31
Filed: 1968-05-02
Abstract: A lead is connected to a semi-conductor device by positioning a semi-conductor pellet on a substrate, arranging a terminal structure so that a contact member of the structure engages the pellet, securing the terminal structure to the substrate so that the contact member is pressed against the pellet, bonding the contact member to the pellet, and disengaging the terminal structure from the substrate. A plurality of connected supports are formed from a strip of nickel-plated copper so that a plurality of semi-conductor devices can be assembled sequentially or simultaneously. As shown, Figs. 6 and 8, each support 12 is provided with a mounting area 16 surrounded by a dovetailed groove 18. A silicon transistor die 44 having a coating of lead on its lower surface and two bonding pads of lead on its upper surface, is positioned on the mounting area 16 and a nickel " clip " 28 is positioned transversely to the support. The clip 28 comprises two side sections 32 connecting end sections 30 from which extend resilient terminal members 36 having bent down end portions 40 which are pressed against the contact pads on the die 44. The side members 32 have recesses (34) which fit over the support 12 and the clip is secured in position by swaging tabs 201 on the support against the side members 32. The assembly is heated to solder the die to the support and the end portions of the terminal members to the contact pads. Encapsulation material is moulded over die 44 and terminal members 36 and enters the dovetail groove 18 which serves to anchor the encapsulation to the support. Each support is then separated from the original strip of supports, the swaged tabs 201 are removed to release the clip and each end section 30 is cut to leave a single strip extending from the encapsulation to form leads to the terminal members 36, Fig. 10 (not shown). In a modification the semi-conductor die is insulated from the substrate by a ceramic plate, for example of beryllia, and three terminal members are provided on the clip. In a second embodiment, Figs. 11 to 13 (not shown), a plurality of dice are positioned on connected supports and are contacted by terminal members extending from a strip which is secured to one edge of the support strip by deforming the sides of a slot in each support around tabs depending from the strip. The devices are then soldered and encapsulated and the strip is then subdivided to form leads for each terminal member and for the tabs secured to the substrates.

Patent ES-358594-A1 (ES)
Title: Improvements in or relating to Microporous Plastics Members and Process for Making Same
IPC: H01M50/417
Filed: 1968-09-27
Abstract: A microporous plastics member, e.g. battery separator sheet, is made by forming a coherent dough by mixing a thermoplastic resin with a plasticizing amount of a first solvent and with finely divided particles of a filler which contains a volatilizable constituent releasable therefrom by heating and which shrinks irreversibly on release of this constituent, forming the dough into a shaped member, extracting the first solvent from the member by contacting it with a second solvent at a temperature below the b.p. of any liquid present, the second solvent being one which can dissolve the first solvent without dissolving the resin and filler, thereby deplasticizing the member, and then heating the member without softening the resin contained therein until the filler is shrunk within the member by release of its volatilizable content. The resin may be polyethylene, polypropylene, polystyrene or polyvinyl chloride. The filler may be powdered hydrated silica, silica hydrogel or diatomite with absorbed water. The first solvent may be a ketone, e.g. cyclohexanone and the second solvent may be water. In the examples, the dough was shaped by extrusion into a sheet.
