Abstract: ABSTRACT:              An electromagnet comprising two cylindrical pole-shoes which are coaxially arranged one in the pro-longation of the other and which are magnetically separat-ed from each other by a magnetically non-conductive inter-mediate ring. Around the pole-shoes an electrical excita-tion coil is arranged for moving an armature which is slidable in the pole-shoes. Pole-shoes, intermediate ring and coil are integrally interconnected by a connect-ing member of synthetic material. The armature can be connected, for example, to a recording pin of a printing device. As a result of the use of the connecting member of synthetic material, the number of operations required for assembling the electromagnet is reduced.

Title: Reduced charge montmorillonite pigment and use in record material
Inventor: ISAAC PETER A H
IPC: B41M5/155
Filed: 1976-11-04
Granted: 1980-01-22
Abstract: ABSTRACT OF THE DISCLOSURE A sheet coated with a reduced charge montmorillonite pigment for use in record material, especially pressure-sensitive carbonless copying systems.  The pigment is produced by replacing exchangeable cations of a substantially dioctahedral montmorillonite (exemplified by certain bentonite clays) with a preselected quantity of lithium ions, mildly heating the lithium-exchanged montmorillonite to collapse irreversibly the montmorillonite structure, and grinding the heat-treated material to pigment-size particles.  The sheets produce stabilized intense images when printed with a solution of crystal violet lactone (CVL) dye precursor and thus may be used with CVL without employing secondary slow acting dyes such as benzoyl leuco methylene blue.  The sheets are also useful with other colorless or substantially colorless dye precursors.

Abstract: ABSTRACT OF THE DISCLOSURE        Polymeric products comprising the acidified reaction product of an organic polyepoxide and a polyamine containing at least two tertiary amine groups are disclosed. The polyamine and the organic polyepoxide are reacted with one another under conditions to form an internally ionized, quaternary ammonium salt group-containing polymer which has a high molecular weight, but relatively low equivalent weight. The poly-amine is formed by reacting an organic polyisocyanate with an active hydrogen-containing tertiary amine.  The reaction product is acidified to form the quaternary ammonium salt groups. Preparing the polyamine in this manner gives one wide latitude in determining the final structure of the polyamine. In effect, one can "tailor make" the polyamine by appropriate selection of reactants and exert a great measure of control over the properties of the final polymeric product. The preferred polymeric products are non-gelled, water-dispersible and electrodepositable on the cathode.
