Title: Stable polymer latex and process for making same
IPC: C08G18/08
Filed: 1971-08-16
Abstract: 1356679 Aqueous polyurethane latices MINNESOTA MINING & MFG CO 10 Aug 1971 [17 Aug 1970] 38391/71 Heading C3R Aqueous polyurethane-urea or polyurea latices comprising a continuous, predominantly aqueous phase and particulate water-insoluble polyurethane-urea or polyurea solids selfemulsified therein, the particulate solids containing at least one hydrophilic terminal group for each 9000 theoretical polymer atomic mass units, the hydrophilic groups being attached at the ends of pendant chains, the pendant chains being 15 to 100 atoms in length may be prepared by modifying polyurethane prepolymers with hydrophilic monofunctional reactants and then chain extending these prepolymers in water. The hydrophilic groups are derived preferably from protonatable tertiary amine compounds, hydrophilic monohydric polymers of ethylene oxide or monoisocyanates, e.g. an isocyanato-arylsulphonic acid. Suitable monofunctional reactants are poly-(oxyethylene) glycol monoesters or monoethers and dialkylalkanolamines. These may be used to modify the prepolymer by reaction thereon. Alternatively the polyol used to form the prepolymer may be premodified by partial capping with, for example, an esterifying agent. Additional amounts of hydrophilic groups may be provided by forming the prepolymer partially from such reactants as methyl diethanolamine or diamino sulphonic acids. If desired, diamines may be added to the water soon after emulsification of the prepolymer, to cause chain extension of the prepolymer. In a typical example polyoxypropylene triol is reacted with toluene diisocyanate to form a prepolymer which is then reacted with diethylethanolamine and added to water containing acetic acid to form a stable cationic latex.

Title: Improvements in or relating to electron beam deflecting systems
Inventor: DIXON RALPH DESMOND
IPC: H01J29/74
Filed: 1956-12-17
Abstract: 827,222. Electron beam deflecting apparatus. GENERAL ELECTRIC CO. Ltd. Oct. 10, 1957 [Dec. 17, 1956], No. 38441/56. Class 39(1). An electron beam deflecting system of increased sensitivity includes primary deflecting means and secondary deflecting means which consisting of two pairs of plates which produce a further deflection of the beam, perpendicular to and proportional to the primary deflection. In one embodiment the plates 1, 2, Fig. 1, form the primary means, and plates 3, 4, 5, 6 form the secondary means. These plates are approximately triangular in shape and are placed so that the distance the beam travels between them is proportional to its primary deflection. Plates 3, 5 are connected together and maintained at a positive potential whilst 4, 6 are maintained at a negative potential, both with respect to the final anode of the electron accelerating system. The line PO indicates the position of the undeflected beam, whilst OX represents a deflection produced by a potential difference between plates 1, 2, and OY represents the resultant deflection produced by the entire system. When the beam is to be deflected in two mutually perpendicular directions it is preferable to apply the system to produce that deflection which occurs most frequently, for example the line scan in a television receiver. In a modification the secondary means comprises plates 7, 8, 9, 10, Fig. 2, of equal length and curved to present their convex surfaces to the beam. Plates 7, 9 are connected to a positive voltage source and plates 8, 10 are connected to a negative voltage source, both with respect to the final anode of the electron accelerating systems. The field between the plates increases with the distance from the centre of the system, thus the deflection produced by the secondary deflection system is again perpendicular to and proportional to the primary deflection. A further increase in sensitivity may be obtained by curving the secondary deflection plates to follow the path of the electron beam, thus reducing the necessary spacing between the plates. The primary deflecting means may be either magnetic or electrostatic.
