Title: Expandable thermoplastic polymeric particles
IPC: C08J9/20
Filed: 1965-03-02
Abstract: Thermoplastic polymeric (e.g. polystyrene) particles (e.g beads) containing uniformly distributed throughout them as an expanding agent, water droplets averaging 5-40m dia., may be prepared by incorporating water as a fine dispersion into the monomer or monomers to be polymerized, and subsequently effecting a suitably catalysed suspension polymerization of the resultant water-in-monomer emulsion in an aqueous medium. The suspension may contain emulsifiers and stabilizers, e.g. ester of an aminated fatty acid mannitol dioleate, methanol, N-vinyl pyrrolidone/methyl acrylate copolymer, polyvinyl alcohol, CMC, water soluble starch, BaSO4 calcium silicate and also foamed polystyrene, or a graft polymer of styrene and ethylene oxides. The polymerization may be catalysed by benzoyl peroxide, tert-butyl perbenzoate, di-tert-butyl peroxide, a -a 1-azobis-isobutyronitrile and/or dicumyl peroxide. Fire retarders e.g. tris-(dibromopropyl)-phosphate dyes and pigments are optional additives. There may additionally be present in the particles a gaseous, volatile or gas-forming compound which is insoluble in water, e.g. pentane or air. Petroleum ether of b.p. 30-70 DEG C. may be added during the polymerization as an anti-coagulant the volatile compound specified above may also be added at this stage. The particles may be foamed by (a) heating in a perforated closed mould (b) extruding at a temperature above the softening-expanding temperature of the particles. They may also be partially expanded e.g. by steam treatment, before finally foaming as above. The particles may be stored, especially if they contain a volatile liquid, for a time sufficient to allow part of this liquid and for the water to evaporate and be replaced by air. The expanded products have a low density, e.g. of the order of 10-15 Kg/M3.

Title: Method of severing a semiconductor wafer
IPC: H01L21/301
Filed: 1968-07-06
Abstract: A semi-conductor wafer is secured to a foil 1 of synthetic resin by electrostatic attraction and is scribed and severed to form a number of segments. The foil 1 is then extended to space the segments apart so as to facilitate inspection and removal thereof, e.g. by a vacuum probe. In the apparatus shown the foil 1 is hermetically sealed to the edge 12 of a housing 15, and is drawn into a chamber 19 and over a plate 29 by vacuum, thereby extending the foil and separating the segments. A lamp arranged above the housing 15 provides the heat necessary to permit stretching. After extension the central part of the foil 1 carrying the spaced segments may be separated from the remainder of the foil. The plate 29 may carry a layer of glue to facilitate manipulation of the separated part of the foil. Initial severing of the scribed wafer is performed by means of a roller which presses the wafer into contact with a resilient pad mounted on a reciprocating support. The method is applicable to the manufacture of transistors or integrated circuits.

Title: Improvements in and relating to integrated capacitor memories
IPC: H03H11/26
Filed: 1969-04-21
Abstract: An integrated capacitor memory used inter alia for delaying transit times of A.F. and V.F. signals comprises a chain of capacitors between which charge can be transferred via a corresponding chain of transistors in response to control signals applied through their bases, the capacitors being constituted by the collector-base capacitances of the transistors, which are formed in islands on a common substrate. Independent signals can be applied to each transistor (Fig. 1, not shown) to give the maximum delay time per transistor but the number of switching sources can be reduced with only a slight loss of delay time by arranging the transistors in a series of groups (Fig. 6) and applying a common signal to the corresponding transistors in each group, which preferably have a common base region with an N+ underlayer, as in the Fig. 10 structure (not shown), which lacks the final diode D of the Fig. 6 circuit. The circuit operates as described in Specification 1,175,600. In Fig. 10 (not shown) the transistors are of lateral type with the emitter and collector zones formed by diffusion into an epitaxial N-type base layer, which may be contacted at one or several points, on a P-type silicon substrate.

Title: Preparation of (cis-1,2-epoxypropyl)phosphonic acid and derivatives thereof
IPC: C07F9/141
Filed: 1969-05-12
Abstract: A compound of the formula wherein R is an ester-forming group is obtained by reacting a phosphite ester P(OR) 3 with a compound of the formula wherein X is a halogen atom or a quaternary ammonium salt radical. The radical R may be alkyl, cycloalkyl, alkenyl, C 2 -C 5 alkynyl, cyano C 1 -C 5 alkyl, aryl, C 1 -C 5 alkyl substituted mononuclear aryl, or aralkyl, and X is halogen, e.g.Cl,Br or I or a quaternary ammonium salt radical, e.g. one having a cation of the formula +-NR1R2R3 wherein R1 is C 1 -C 5 alkyl and R2 and R3 are each C 1 -C 5 alkyl or R2 and R3 together with the N atom form a heterocyclic group, e.g. piperidino. The reaction is generally carried out in an inert solvent and the isomeric ester mixture formed can be separated, e.g. by gas- or adsorption chromatography, to yield the esters of ( ) cis- and ( ) trans - (1,2 - epoxypropyl) phosphonic acid. The esters of the ( ) cis acid can be converted to the free acid or salts thereof, which have antibiotic properties, by various defined methods and the free acid can be converted to alkali metal-or alkaline earth metal salts or to the amine salts by treatment with an appropriate base. The 1,X-1,2-propylene oxide compounds of Formula I in which X is halogen may be obtained by treating a compound of the formula CH 3 CH = CHX with an oxidizing agent, e.g. perbenzoic acid, metachloroperbenzoic acid, trifluoroperacetic acid or perphthalic acid. The compounds I in which X is a quaternary ammonium salt radical are obtained by reacting an a-halopropionaldehyde with a secondary amine, e.g. piperidine, in the presence of a base and then reacting the product with a C 1 -C 5 alkyl iodide. Tricyanoethyl phosphite is obtained by reacting #-hydroxypropionitrile in benzene with PCl 3 in triethylamine at 10 C. Tri-tert butyl phosphite is obtained similarly using tertbutanol instead of the #-hydroxy propionitrile.
