Title: Actuator arm assembly with self-locking arm
Inventor: BAASCH HOLGER JOHAN
IPC: G11B21/26
Filed: 1995-09-11
Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.

Patent CA-2167853-A1 (CA)
Inventor: SZYJKOWSKI JERZY
IPC: E04B9/00
Filed: 1996-01-23
Abstract: This fastening mechanism for access panels and grills is design for use in a variety of applications, where the opening is made in any kind of paneling, plastic or sheet metal structures, or applience. Majority of use will be found in openings in paneling of walls and ceilings and in duct works in building constructions. The system enables for a fast and rigid installation of access panels and grills, in which it is only required to make an adequate opening in paneling or sheet metal etc., without having to install any frame, and/or having to attach the grills to the studs. In this invention the rotation of a single screw enables for the installation or removal of the access panel or grill, which rotation causes the fastening arm to swing in to insert/remove position and to tighten of the panel in place after the arm automatically returns to the installation position.  Reverse rotation of the screw will loosen the panel or grill and enables for removal of the access door from the opening.

Patent CA-2175555-A1 (CA)
Inventor: SCHMITZ CHRISTOPH
IPC: A61F13/15
Filed: 1994-10-26
Abstract: The invention relates to a method of manufacturing an absorbent article, wherein the speed of a part of a continuously moving web comprising a topsheet, backsheet, core or any combination thereof, is periodically varied, while maintaining a constant speed of the upstream and downstream parts of the web. The method comprises feeding the web past rotating transport rollers which are oscillated parallel to the web in the direction of transport and opposite to the direction of transport. Three web sections are during oscillation of the transport rollers maintained in a mutually parallel relationship. Translation- and rotation balancing means allow the transport rollers to be driven at high speeds and low variations in torque. The strain exerted on the web remains relatively low and is limited to the inertia forces that act on the web. <IMAGE>
