Title: Electric fastener driving tool
IPC: B25C1/06
Filed: 1976-06-04
Abstract: An electric fastener driving tool includes a body of clamshell construction formed of two, similar, molded plastic body parts. The body includes a head portion and a handle portion, and a magazine for supplying fasteners to be driven is supported by the base of the head portion and by the handle. Walls and projections integral with the body parts define a solenoid chamber within the head cavity and support a switch and circuit board within the handle. The body is held in assembled condition and the magazine is attached to the body by bolts of equal length. A solenoid with a central axial opening is mounted in the solenoid chamber. An armature formed of magnetic and nonmagnetic, electrically insulated segments is slidably mounted in the axial solenoid opening. A spring contacting an integral body wall and the insulating armature segment biases the armature in the return direction. A driver blade carried by the armature may be attached in electrically insulated fashion, and moves in a drive path into which fasteners are supplied from the magazine. A circuit including a switch controls energization of the solenoid, and a switch operating assembly provides for fail-safe operation and prevents unintentional multiple firing.

Title: Liquid crystal cell.
IPC: G02F1/1337
Filed: 1980-04-15
Abstract: A liquid crystal cell includes a cholesteric liquid crytal between two aligning surfaces. The cell has two stable states (A and C) in which the active region is substantially free from disclinations and walls. The cell can be switched between stable states by applying an alternating electric field to bring the cell to an unstable state (B) from which it relaxes to one or other of the stable states depending on how the field is removed, for example whether it is removed abruptly or gradually. Since both of the stable states are stable, no energy is required to maintain them, only to switch between them. The cell has applications to light valves and displays.

Title: Method for preventing polymer scale deposition in the polymerization of ethylenically unsaturated monomers.
IPC: C08F2/00
Filed: 1982-03-23
Abstract: The invention provides a very efficient method with highly durable effect for preventing polymer scale deposition on the reactor walls and other surfaces coming into contact with the monomer during polymerization of an ethylenically unsaturated polymerizable monomer in an aqueous medium such as in the suspension polymerization of vinyl chloride.

Title: Rotor blade or rotor blade component and process for the production thereof.
IPC: B64C27/46
Filed: 1982-04-08
Abstract: A large surface structural component, such as a rotor blade for a windmill or a blade root for a windmill rotor, includes a hollow core (6) of foam material supporting a shell (8, 11) of fiber reinforced synthetic material. Positive templates in the form of disks (5) are inserted into the core (6).
